    Figure 1 is a perspective view of a sensor cleaning device 1 according to one embodiment. FIG. 2 is an exploded perspective view of an injection nozzle 10 included in the sensor cleaning device 1. The sensor cleaning device 1 is a cleaning device intended to clean foreign bodies fixed on an external sensor (not shown; an example of the object to be cleaned) mounted on a vehicle and which acquires information outside the vehicle by blowing a cleaning liquid (an example of the cleaning fluid) onto the external sensor. Examples of the external sensor include a laser radar, a camera, a millimeter wave sensor, and the like.
    As shown in Figures 1 and 2, the sensor cleaning device 1 comprises a cylinder 2, a piston 3, and a pair of injection nozzles 10, 10 (an example of the device nozzle vehicle cleaning).
    The cylinder 2 is formed in a cylindrical shape, and a connecting part 4 is formed on the rear side thereof. A pipe connected to a cleaning liquid tank (not shown) in which cleaning liquid is stored is connected to the connecting portion 4, so that the cleaning liquid is supplied from the cleaning liquid tank into the cylinder 2. The cylinder is provided in an opening part (not shown; corresponding to a second opening part) formed in a part of a body panel (not shown) of the vehicle (not shown).
    The piston 3 is slidably received in the cylindrical cylinder 2. The piston 3 can move back and forth along the central axis of the cylinder 2.
    The injection nozzles 10, 10 are provided in pairs on the left and on the right in the vicinity of the front end of the piston 3. The injection nozzles 10, 10 are nozzles capable of injecting liquid cleaning to a sensor (not shown) of a vehicle. The pair of injection nozzles 10, 10 has the same configuration. Consequently, in the description which follows, the injection nozzle 10 on the right side will be described. Furthermore, the injection nozzle 10 can be provided only on one side in the vicinity of the front end of the piston 3.
    The injection nozzle 10 comprises a nozzle housing 12, a nozzle tip 14, and a nozzle holder 16. The nozzle housing 12 receives the nozzle tip 14. The nozzle housing 12 is assembled on the nozzle holder 16 in a state where the nozzle tip 14 is received in the nozzle housing 12. As shown in Figure 2, the nozzle housing 12, the nozzle tip 14, and the nozzle holder 16 can be assembled along the same direction D. That is, the nozzle housing 12 receives the nozzle tip 14 along the direction D and is assembled on the nozzle support 16 along the direction D in a state where the nozzle tip 14 is received.
    FIG. 3A is a perspective view from above of the nozzle housing 12, and FIG. 3B is a perspective view from below of the nozzle housing 12.
    As shown in Figures 3A and 3B, the nozzle housing 12 has a cylindrical base part 21, and a tip receiving part 22 provided above the base part 21. The interior of the base 21 and the tip receiving part 22 function as a receiving space 23. A projecting part 24 intended to form an oscillation chamber 50 (to be described later) is provided to protrude into the receiving space 23. An injection port 25 for injecting cleaning liquid towards an external sensor is formed on the rear side of the tip receiving part 22.
    Figure 4A is a perspective view from above of the nozzle tip 14, and Figure 4B is a perspective view from below of the nozzle tip 14. As shown in Figures 4A and 4B, nozzle tip 14 has a flat base portion 31, and a pair of protrusions 32 provided to project upward from the base portion 31. In addition, a recessed portion 33 is formed on a bottom surface of the portion base 31 so as to be recessed upwards. The recessed portion 33 is surrounded by a frame portion 34 constituting a portion of the base portion 31. The front side of the frame portion 34 is cut. This cut portion 35 constitutes a communication passage 52 through which cleaning fluid flows from the recessed portion 33 to the oscillation chamber 50 (see Figures 7 and 8) in a state where the nozzle tip 14 is received in the nozzle housing 12.
    Returning to FIG. 2, the nozzle support 16 has a piston connection part 41 connected to the piston 3, and a nozzle holding part 42 provided so as to extend to the right of the piston connection part 4L A cylindrical nozzle connection part 43 is provided on an upper surface of the nozzle holding part 42. The base part 21 of the nozzle housing 12 is connected to the nozzle connection part 43, so that the nozzle housing 12 is assembled on the nozzle support 16. An opening part 44 is formed inside the nozzle connection part 43.
    Figure 5 is a side view of the front side of the sensor cleaning device 1. Figure 6 is a sectional view along the line AA in Figure 5, Figure 7 is a sectional view along the line BB in Figure 5, and Figure 8 is a sectional view taken along line CC in Figure 5. As shown in Figures 6 and 8, in a state where the nozzle housing 12 receives the nozzle tip 14 is assembled on the nozzle support 16, a space 51 is defined between the recessed portion 33 of the nozzle tip 14 and the nozzle connection portion 43 of the nozzle support 16. In addition, the oscillation chamber 50 (l the receiving space 23) is defined between the tip receiving portion 22 of the nozzle housing 12 and the base portion 31 of the nozzle tip 14. In addition, the communication passage 52 communicating the space 51 and the oscillation chamber 50 with each other is defined by the peak receiving part 22 of the nozzle housing 12 and the cut-out part 35 of the nozzle tip 14. In this way, the cleaning liquid supplied from the connection part 4 of the cylinder 2 passes through the interior of the holding part of the nozzle. nozzle 42 via the piston connection part 41, is further supplied to the space 51 via the opening part 44, and is then supplied to the oscillation chamber 50 by the communication passage 52.
    As shown in Figure 7, the injection nozzle 10 operates as a fluid type nozzle (oscillating injection nozzle) by means of the oscillation chamber 50 which is formed by the receiving part of tip 22 of the nozzle housing 12 and of the nozzle tip 14. The fluid type nozzle relates to a nozzle which performs a control by interfering with the flow of fluid and by deflecting its flow passage. As shown in FIG. 9, the injection nozzle 10 such as the fluid type nozzle can change an injection direction P of the cleaning liquid in the left and right direction by deflecting the flow passage of the cleaning liquid. cleaning injected from injection port 25.
    More specifically, as shown in Figure 7, in a state where the nozzle tip 14 is received in the tip receiving portion 22 of the nozzle housing 12, the communication passage 52, the chamber oscillation 50, a pair of return flow passages 55, 56, and the injection port 25 are formed inside the injection nozzle 10. The oscillation chamber 50 is formed continuously with the communication passage 52, and the cleaning liquid is supplied to the oscillation chamber 50 from the communication passage 52.
    The passages of the pair of return flow passages 55, 56 are flow passages defined between the projecting part 24 of the tip receiving part 22 and the projecting parts 32 of the nozzle tip 14 and are provided respectively on the left and right sides of the oscillation chamber 50. The return flow passages 55, 56 have inlets 55A, 56A which open onto the oscillation chamber 50 on the outlet side of the oscillation chamber 50 (on the side of the injection orifice 25) and outlets 55B, 56B which open onto the oscillation chamber 50 on the inlet side of the oscillation chamber 50 (on the side of the communication passage 52). In this way, the return flow passages 55, 56 are configured to respectively branch and guide a part of the cleaning liquid supplied from the communication passage 52 to the oscillation chamber 50 from the inputs 55A, 56A to the outlets 55B, 56B and to return the cleaning liquid to the oscillation chamber 50 again.
    More specifically, part of the cleaning liquid flowing in the oscillation chamber 50 from the communication passage 52 first flows in the return flow passage 55 through the inlet 55A of the return flow passage 55 and flows into the oscillation chamber 50 through the outlet 55B. Then, part of the cleaning liquid in the oscillation chamber 50 flows into the return flow passage 56 through the inlet 56A of the return flow passage 56 and flows into the return chamber. oscillation 50 through output 56B. Then, part of the cleaning liquid in the oscillation chamber 50 again branches to the return flow passage 55 and flows back into the oscillation chamber 50 through the outlet 55B. When this cycle is repeated, the cleaning liquid alternately guided by the return flow passages 55, 56 becomes what is called a "return control flow" to self-oscillate the cleaning liquid which flows to through the oscillation chamber 50, so that the cleaning liquid can be swept and injected (diffused and injected) in the left and right direction from the injection port 25. In this way, the nozzle housing 12 and the nozzle tip 14 are assembled, so that the injection nozzle 10 can be configured as the fluid type nozzle. As a result, the injection nozzle 10 can inject the cleaning liquid to the external sensor at high pressure while sweeping the cleaning liquid in the left and right direction.
    Figures 10 and 11 are perspective views of the sensor cleaning device 1, showing a pivoted state of the injection nozzle 10. As shown in Figure 10, the injection nozzle 10 is mounted so that the nozzle housing 12 can pivot relative to the nozzle holder 16 about an axis along the up and down direction. In addition, as shown in Figure 11, the injection nozzle 10 is mounted such that the nozzle holder 16 can pivot relative to the piston 3 about an axis along the left and right direction. In this way, by appropriately rotating the nozzle housing 12 and the nozzle holder 16 when fixing the injection nozzle 10 on the piston 3, the injection orifice 25 of the injection nozzle 10 can be oriented in an appropriate position depending on the positional relationship between the external sensor and the injection nozzle 10. In this way, the position of the injection nozzle 10 can be adjusted so that the cleaning properly hits the external sensor.
    As described above, the injection nozzle 10 for the sensor cleaning device 1 according to the present embodiment comprises the nozzle housing 12 (an example of the housing), the nozzle tip 14 received inside the nozzle housing 12, and the nozzle support 16 (an example of the support) for supporting the nozzle housing 12 in a state of reception of the nozzle tip 14. In addition, in the nozzle d Injecting 10, the nozzle tip 14 is received in the nozzle housing 12, so that the return flow passages 55, 56 for sweeping and injecting the cleaning liquid are formed. According to this configuration, the return flow passages 55, 56 are formed between the nozzle housing 12 and the nozzle tip 14 received in the nozzle housing 12, so that the cleaning liquid can be swept and injected. In addition, since the nozzle housing 12 itself is configured as part of an element for forming the return flow passages 55, 56, the nozzle housing 12 and the nozzle tip 14 can be formed in a small size, and the injection nozzle 10 can be miniaturized.
    In addition, according to the injection nozzle 10 of the present embodiment, the nozzle housing 12 has the inner wall (the projecting part 24) intended to form the receiving space 23 (first opening part ) in which the nozzle tip 14 is received, and the nozzle tip 14 has the pair of projections 32 forming the oscillation chamber 50 (the oscillation space) between the receiving space 23 of the nozzle housing 12 and the nozzle tip 14. In a state where the nozzle tip 14 is received in the nozzle housing 12, the pair of return flow passages 55, 56 is formed between the projection 24 of the nozzle housing 12 and each part of the pair of protrusions 32 of the nozzle tip 14. According to this configuration, the oscillation chamber 50 and the return flow passages 55, 56 can be easily formed with a simple configuration to receive in a manner single nozzle tip 14 in the receiving space 23 of the nozzle housing 12.
    In addition, according to the injection nozzle 10 of the present embodiment, during the assembly of the injection nozzle 10 on the piston 3, first of all, the nozzle tip 14 is assembled on the nozzle housing 12 along direction D (an example of the first direction) shown in Figure 2. In this way, the return flow passages 55, 56 for sweeping and injecting the cleaning liquid injection port 25 are formed. Then, the nozzle housing 12 in a state of reception of the nozzle tip 14 is assembled on the nozzle support 16 supported by the piston along the direction D. In this way, the nozzle housing 12, the tip of nozzle 14, and the nozzle holder 16, which constitute the injection nozzle 10, can be assembled along the same direction (direction D), so that it is possible to improve the working efficiency at when the injection nozzle 10 is assembled.

In addition, the materials, shapes, dimensions, numerical values, shapes, number, and arrangement locations and the like of each component in the embodiments described above are arbitrary and are not limited, as long as this presentation can be implemented.
    The injection nozzle 10 in the above embodiments is fixed on the sensor cleaning device 1 to inject a cleaning liquid to an external sensor which acquires information outside of a vehicle. However, the injection nozzle 10 is not limited to this example. The injection nozzle having the above configuration can be fixed on a fire cleaning device which is used to clean a vehicle fire by injecting a cleaning liquid on the vehicle fire.
