    Description
    Technical Field [0001] The present invention relates to a suction brush intended to be connected to a suction system for cleaning and deburring small components.
    STATE OF THE ART [0002] Known suction brushes, intended to be connected to a suction system generally comprise a connection part connectable to the suction system and a brush part comprising bristles. These are generally fixed to the brush part directly by gluing. The hairs are also held together by a string. Often the bristles are tied in tufts and the tufts are then attached to the brush part, for example by gluing. In this case, mounting the bristles on the brush part is laborious. In document DE1246951, the bristles are attached to the nozzle of the brush by means of magnets.
    Brief summary of the invention The present invention relates to a suction brush which can be connected to a suction system, the brush comprising: a first tube having a first bore and a second bore; a second tube comprising a proximal portion configured to be driven into the first bore, and a distal portion extending into the second bore; the distal portion and the second bore being configured to form a cavity capable of receiving a plurality of brush bristles and to hold said plurality of bristles fixed so that they extend distally, when the proximal portion is driven into the first bore.
    The present invention also relates to a mounting method comprising the steps of; provide the brush; driving the distal portion of the second tube into the first bore; and fixing the plurality of hairs in the cavity.
    The present invention further relates to a suction system comprising suction means and a suction tube configured to come and connect the proximal part of the brush.
    This solution has the particular advantage over the prior art of providing a simplified brush. Maintaining the bristles on the brush is improved compared to known brushes. The absence of a twine to hold the hairs avoids pollution due to loss of particles from the twine. The bristles of the brush is also easier to clean. The solution also includes a simplified method for mounting the bristles on the brush.
    Brief description of the figures [0007] Examples of implementation of the invention are indicated in the description illustrated by the appended figures in which:
    fig. 1 a sectional view of a suction brush, according to one embodiment;
    fig. 2 shows another sectional view of the suction brush, according to one embodiment; and fig. 3 shows a detail of the distal part of the suction brush, according to one embodiment.
    Example (s) of embodiment [0008] FIG. 1 shows a sectional view of a suction brush 1, according to one embodiment. The brush 1 comprises a first tube 2 comprising a first bore 23 and a second bore 24. The first tube 2 also includes a proximal part 25 intended to be connected to a suction system (not shown). In the example illustrated, the proximal part 25 is provided with flexible elements 26 allowing the mounting, for example by clipping, of the proximal part 25 in a suction tube of a suction system.
    A second tube 3 includes a proximal portion 31 which is configured to be driven into the first bore 23 of the first tube 2. The second tube 3 also includes a distal portion 32 extending distally in the second bore 24 when the portion proximal 31 is driven into the first bore 23. When the second tube 3 is driven, the latter as well as the first tube 2 extend coaxial with the axis 10.
    In this way, a cavity 33 is formed between the internal wall 27 of the second bore 24 and second tube 3. The cavity 33 is configured to receive a plurality of bristles 4 of the brush and to keep the bristles 4 fixed between the wall internal 27 of the second bore 24 and second tube 3, so that they extend distally, when the proximal portion 31 is driven into the first bore 23. FIG. 2 shows a sectional view of a suction brush 1 in which the bristles are not shown.
    The second tube 3 is provided with a third bore 35. Once the distal portion 32 of the second tube 3 is driven into the first bore 23, the first bore 23 and the third bore 35 form a suction channel 20
    CH 713 084 A2 when the proximal part 25 is connected to the suction system. The second tube 3 may include a flared tip 36 (drowning). The recess 36 can be used for the operation of driving the proximal portion 31 of the second tube 3 into the first bore 23, for example by allowing to apply a pressure aligned in a proximal direction. To this end, the top 37 (see FIG. 2) of the recess 36 can advantageously be flat.
    The distal portion 32 and the second bore 24 may have a circular section, so that the plurality of bristles 4 fixed in the cavity 33 form a circular crown. The distal portion 32 and the second bore 24 may have a section having a shape other than circular, for example a square, hexagonal or other section.
    Alternatively, the distal portion 32 and the second bore 24 have a frustoconical shape widening distally so that the bristles 4 widen distally, that is to say extend distally forming an angle 9 with the axis 10. The distal portion 32 of the second tube may also comprise an external wall 28 inclined at substantially the same angle 9 with the axis 10 so that the internal internal wall 27 of the second bore 24 and the outer wall 28 of the distal portion 32 are substantially parallel. It will be understood that other arrangements of the distal portion 32 and of the second bore 24 are also possible. For example, the distal portion 32 and the second bore 24 can extend distally substantially parallel to the axis or even be inclined at an angle 9 closed with the axis 10 so that the bristles 4 are tightened distally. The distal portion 32 and the second bore 24 can also extend distally substantially parallel to the axis 10.
    According to one embodiment, the distal portion 32 is provided with a collar 34 at its periphery. When the distal portion 32 of the second tube 3 is driven into the first bore 23, the flange 34 presses the bristles 4 against the internal internal wall 27 of the second bore 24, making it possible to keep the bristles fixed in the cavity 33.
    [0015] FIG. 3 shows a detail of the distal part of the suction brush. The configuration of the collar 43 can vary according to the type of bristles to fix the cavity 33. For example, the ratio of the depth d! of the cavity 33 over the distance d 2 between the bottom of the cavity 33 and the flange 43 is between 10 and 5 and preferably between 6 and 7. The ratio of the width d 3 of the flange 34 to the depth di of the cavity 33 can be between 10 and 4 and preferably between 6 and 5. The ratio of the spacing between the inner inner wall 27 of the second bore 24 and the outer wall 28 of the distal portion 32 and the spacing e 2 between the internal wall 27 and the collar 34 is between 1.5 and 1.2.
    Still according to one embodiment, when the proximal portion 31 is driven into the first bore 23, the distal portion 32 of the second tube 3 extends distally beyond the second bore 24.
    According to one embodiment, a method of mounting the brush 1 comprises driving the distal portion 32 of the second tube 3 into the first bore 23 and fixing the bristles 4 in the cavity 33. The bristles 4 can be fixed in the cavity 33 before hunting or after. During assembly, the bristles 4 can be glued into the cavity 33.
    The suction brush 1 described here can advantageously be used for cleaning and / or deburring small components such as, for example, electronic components or watch components.
    The present invention also relates to a suction system (not shown) comprising the brush 1 described above. The suction system comprises suction means (motor, etc.) and a suction tube to which the proximal part 25 of the brush 1 is connected, for example by mounting / clipping (see above). The suction system can be configured so that it can be connected to several variants of brush 1.
    For example, a brush 1 in which the distal portion 32 and the second bore 24 have a frustoconical shape so that the bristles 4 widen or tighten distally, or a brush 1 in which, when the proximal portion 31 is driven into the first bore 23, the distal portion 32 of the second tube 3 extends distally beyond the second bore 24 or even at the same distance (so as to provide a more flexible brush).
