    TECHNICAL AREA
    The present invention relates to a sanitary field, and more particularly to an easily identifiable switching valve of the adjustable temperature type.
    BACKGROUND
    The operation of the traditional compression switching structure has certain defects. During the opening and closing process by pushing and releasing, the actuating force of the user must overcome the hydraulic pressure of the hydraulic chamber. Since the necessary actuation force is too great, it can not be applied to all users, especially users with little strength. In addition, the actuating rod of the current compression switching structure has a short distance from a plug hole. If the user exerts a large operating force while pushing, the actuating force acts excessively on the shutter hole and then destroys the element having the shutter hole. As a result, a service life of the element having the shutter hole is considerably reduced.
    In addition, the current compression switching structure only has a switching function, without a temperature setting function. In addition, the current compression switching structure has a short compression stroke, and thus it is difficult to identify the state in which the structure is located. In the event of a water cutoff, it is impossible to know the switching status. Therefore, the current compression switching structure needs to be improved.

The temperature setting member 8 comprises a temperature control member 8. mobile ceramic 81 fixedly connected to the inner casing 2 and a static ceramic piece 82 connected to the valve core seat 7, wherein the movable ceramic piece 81 provides thereon an evacuation portion 810 communicating with the discharge opening 20 and the static ceramic piece 82 separately supplies thereon a cold water inlet 821 and a hot water inlet 822.
    Here, the control rod 3 provides thereon a sealing portion 30 made of soft rubber and fitted on one end of the control rod 3. The control rod 3 is caused by the actuating mechanism to move, and the sealing portion 30 of the control rod 3 moves together with the control rod 3 to open or block the depressurizing water passage 421 provided in the pressure seat 42, causing the hydraulic chamber 420 to open or close, so that the first sealing member 41 is detached from the inlet 20 to form a water outlet flow or presses against the discharge opening 20. When turning the actuating mechanism , the inner casing 2 and the movable ceramic part 81 are pivoted, so that the evacuation portion 810 of the movable ceramic piece 81 optionally corresponds to the cold water inlet 821 or to the inlet hot water 822 from the room static ceramic 82 or partially corresponds to the cold water inlet 821 and the hot water inlet 822 of the static ceramic piece 82 for a water inlet flow.
    More specifically, the actuating mechanism includes a compression structure 6 provided with a ratchet pusher rod 61, a rotatable inner rod 62 and a ratchet seat 63, a connecting rod 51 cooperating with the strut structure. 6 and connected to the control rod 3 with one end, a second spring 52 located in the valve core casing 1 and acting between the pressure seat 42 and the compression structure 6, and a third spring 53 located in the connecting rod 51. When the compression structure 6 is caused to move, the third spring 53 then compresses to bring the connecting rod 51 to move, and then brings the sealing portion 30 together with the control rod 3 to move to open or close the depressurizing water passage 421 of the pressure seat 42.
    One end of the ratchet pusher rod 61 is a compression-actuated end 611, which passes through the ratchet seat 63, and the other end of the ratchet pusher rod 61 has a movable pawl 612. The rotatable inner rod 62 is nested in the ratchet push rod 61 and provides on the outer wall thereof a pawl portion 622 engaged with the movable pawl 612, and a limit portion 630 for rotatably suspending the ratchet portion 622 is provided in the seat to Here, when the compression-actuated end 611 is squeezed to push the movable pawl 612 onto the ratchet pusher rod 61 to cause the pawl portion 622 to move, the ratchet portion 622 is caused to pivot and to hang further on the boundary portion 630 or detach, so that the connecting rod 51 engages the rotating inner shaft 62 is moved.
    In a particular embodiment, shown in FIGS. 1 to 6, the invention discloses an easily identifiable switching valve of the adjustable temperature type, mainly including the following: a valve core casing 1, an inner casing 2 , a control rod 3, a sealing portion 30, a first sealing member 41, a pressure seat 42, a connecting rod 51, a second spring 52, a third spring 53, a pusher pusher rod 61, a internal rotating rod 62, a ratchet seat 63, a valve core seat 7, a movable ceramic piece 81 and a static ceramic piece 82.
    In the assembly, at the time of assembling the temperature adjusting member 8, the static ceramic piece 82 is fixedly installed in the valve core seat 7. The movable ceramic piece 81 is fixedly connected to the inner casing 2 by a snap joint, and is rotated by the inner casing 2. The inner casing 2 is then engaged with and connected to the valve core seat 7.
    When assembling the inner casing 2, the first spring 43 is first put in the pressurized seat 42, and the first sealing member 41 is installed and moves in the pressurized seat 42 and pushes against the first spring 43. The sealing piston member 4 is installed in one piece with the inner casing 2 to ensure that the first sealing member 41 is installed corresponding to the position of the opening evacuation 20.
    During the assembly of the actuating mechanism, the sealing portion 30 is first installed on the control rod 3. The second spring 52 is then fitted onto the connecting rod 51. The control rod 3 is then connected to cooperatively at one end of the connecting rod 51, so that the control rod 3 moves in synchronism with the movement of the connecting rod 51. Next, the rotating inner rod 62 is installed to correspond with the ratchet push rod 61 and be fitted therein. The compression actuated end 611 at one end of the pusher pusher rod 61 extends through the valve core casing 1, and the movable pawl 612 at the other end of the pusher pusher rod 61 is in engagement with the ratchet portion 622 of the rotatable inner rod 62. Finally, once the third spring 53 has been put into the connecting rod 51, the rotatable inner rod 62 is engaged with the third spring 53 and connected to this one.
    With regard to the assembly of the body, once the temperature adjusting element 8, the inner casing 2 and the actuating mechanism have been assembled, the core casing 1 is connected in one piece. at the valve core seat 7, and the assembly process is thus fully completed.
    In practical operation, the compression-actuated end 611 of the ratchet pusher rod 61 is compressed, the compressive force on the ratchet pusher rod 61 overcomes the biasing force of the third spring 53 and further pushes the inner rod rotary 62 and connecting rod 51 to move downwards, and then causes the sealing portion 30 and the control rod 3 to move downwardly, so that the water inlet of the water passage of depressurization 421 of the pressure seat 42 is blocked by the sealing portion 30 of the control rod 3. When the compressive force is eliminated, the mobile pawl 612 of the ratchet pusher rod 61 bounces under the force of the second spring 52 and leads the rotating inner shaft 62 to be rotated by a certain degree, so that the pawl portion 622 of the rotating inner shaft 62 is engaged with the boundary portion 630 in the core shell 1 and suspended therefrom. At this stage, the water inlet of the depressurizing water passage 421 is still blocked by the sealing portion 30 of the control rod 3 to be maintained in a sealing state. At this point, under the force of the second spring 52, the depressurizing water passage 421 of the pressurized seat 42 remains firmly locked by the control rod 3 and the soft rubber seal 30 thereon, and the water of the hydraulic chamber 420 can not be removed, so that the hydraulic pressure of the hydraulic chamber 420 is greater than the pressure at the water inlet of the inner casing 2. Because of the higher pressure of the hydraulic chamber 420, the first sealing member 41 presses against the discharge opening 20 and the passage of the water outlet stream can not open.
    When the compression-actuated end 611 of the ratchet pusher rod 61 is compressed again, the rotatable inner shaft 62 is caused to move by the ratchet pusher shaft 61 under the compressive force. When the compressive force is removed, under the force of the second spring 52, the rotating inner rod 62 returns to pivot in the initial position, and the pawl portion 622 detaches from the boundary portion 630. At this point, the pressure on the connecting rod 51 disappears and causes the seal portion 30 together with the control rod 3 to move upward to open the water inlet of the depressurizing water passage 421 of the reflux chamber 423, and the The water thus evacuates outside the depressurizing water passage 421, so that the pressure of the hydraulic chamber 420 and the pressure at the discharge opening 20 are immediately imbalanced. The pressure of the hydraulic chamber 420 is less than the pressure at the discharge opening 20, and the first sealing member 41 is thus pushed back, so that a large amount of water is removed from the outlet of the outlet. water to form a water outflow. The temperature can be adjusted once the water outlet flow has formed: the ratchet seat 63 is rotated to cause the inner casing 2 and the movable ceramic piece 81 to rotate, so that the portion of 810 evacuation of the movable ceramic piece 81 optionally corresponds to the cold water inlet 821 to form a cold water outlet flow or the hot water inlet 822 to form a water outlet flow hot, or partially corresponds to the two water inlets 821,822 to form a mixed water outlet flow. The invention provides a switching valve easily identifiable and temperature-adjustable type, a simple structure and easy to implement. It depressurises the hydraulic chamber via a control rod, so that the switch can be operated with only a low actuation force and thus the necessary compression actuation force is reduced. In addition, the temperature can be effectively controlled by changing the water inlet discharge area through a moving ceramic piece and a static ceramic piece, and an effective temperature setting function is thereby ensured. The invention provides the first spring acting on the sealing member, which can provide the sealing effect, so that the sealing piece can press against the discharge opening or open it. The pressure seat of the invention has a special depressurizing water passage, whose direction of flow is the same as the control direction of the control rod, so as to further reduce the compressive force and facilitate the depressurization. The actuating mechanism of the invention can realize a longer compression stroke, therefore, not only is the compressive force reduced, but an open state or a closed state can also be visually evaluated and the process compression can be felt to the touch. The elements inside the switching valve are not damaged or broken due to excessive actuating force and these elements are protected and their service life is prolonged. The control mechanism of the invention has an additional function of automatically locking the switching water passage, which is achieved by using the limit portion of the ratchet seat as a limit position, without any other mechanism, so that the Blocking effect is better and stable in case of lack of water inlet flow.
