[0036] In order to make the technical scheme and characteristics of the utility model more clear, the utility model is further explained in detail in the following with reference to the drawings and specific examples, and it should be understood that these examples are only used for explaining the utility model and not for limiting the scope of the utility model, and after reading the utility model, the modification of various equivalent forms of the utility model by the person skilled in the art falls within the range defined by the appended claims of the application.
[0037] REFERENCEFigures 1-9 The embodiment provides a shower device, which comprises a water outlet terminal, a shower controller 1 and a pipeline connecting the water outlet terminal and the shower controller 1. By installing a press switch valve core 2 on the shower controller 1, water supply or water stop of the corresponding water outlet terminal can be controlled.
[0038] In order to install a sufficient number of press switch valve cores 2 so that the shower controller 1 can control more water outlet terminals, the shower controller 1 in the embodiment comprises a control base 11 and four press switch valve cores 2 as described above; part of the press switch valve cores 2 is arranged in the control base 11, namely Figure 3 the dashed part in the middle, and the rest is exposed outside the control base 11 to reduce the volume of the press switch valve core 2 in the control base 11. In this way, part of the press switch valve core 2 is arranged in the control base 11, so only this part occupies the space in the control base 11, thereby greatly reducing the volume of the press switch valve core 2 in the control base 11 compared with the solution of arranging the press switch valve core 2 in the control base 11 as a whole, so that more press switch valve cores 2 can be installed without reducing the volume of the press switch valve core 2, thereby realizing the installation of as many press switch valve cores 2 as possible without sacrificing the flow to control more water outlet terminals. The four press switch valve cores 2 in the embodiment correspond to the control of four water outlet terminals respectively.
[0039] The press switch valve core 2 in the embodiment can reduce the pressing stroke required by the user when operating, thereby achieving a better operation feeling. To this end, the press switch valve core 2 comprises a key 21, a swing piece 22, a switching assembly 23 and a valve body 24, the key 21 is connected with the switching assembly 23 through the swing piece 22 to drive the switching assembly 23 to switch between the water supply position and the water stop position, the distance between the action point of the key 21 and the swing piece 22 and the swing point of the swing piece 22 is S1, the distance between the action point of the swing piece 22 and the switching assembly 23 and the swing point of the swing piece 22 is S2, S1 < S2: Since the action point of the key 21 and the swing piece 22 is closer to the swing point, in the case of swinging the same central angle, the stroke of the key 21 is relatively small, and the stroke of the switching assembly 23 is relatively large. Thus, the stroke brought by the user pressing the key 21 is amplified by the swing piece 22, and the effect of the micro switch is achieved, that is, the user only needs to press the key 21 to bring a relatively small stroke, which is amplified by the swing piece 22 to a relatively large stroke of the switching assembly 23 to complete the whole switching process.
[0040] To realize the opening and closing of the press switch valve core 2, the valve body 24 has a first water inlet cavity 241 and a water outlet flow channel 242, and a sealing assembly 243 and a shell 246 arranged between the first water inlet cavity 241 and the water outlet flow channel 242, and the second water inlet cavity 244 is formed between the sealing assembly 243 and the shell 246; the first water inlet cavity 241 communicates with the second water inlet cavity 244, and the action area of the second water inlet cavity 244 and the sealing assembly 243 is greater than that of the first water inlet cavity 241 and the sealing assembly 243; the valve body 24 further comprises a pressure relief cavity 245; when the switching assembly 23 is located at the water closing position, the switching assembly 23 seals the communication between the pressure relief cavity 245 and the second water inlet cavity 244, at this time the water flow only exists in the first water inlet cavity 241 and the second water inlet cavity 244, and because the action area of the second water inlet cavity 244 and the sealing assembly 243 is greater than that of the first water inlet cavity 241 and the sealing assembly 243, the sealing assembly 243 is subjected to a greater force from the water on the side of the second water inlet cavity 244, and the sealing assembly 243 seals the communication between the first water inlet cavity 241 and the water outlet flow channel 242 under the action of the water in the second water inlet cavity 244, thereby completing the water closing. When the switching assembly 23 is located at the water opening position, the switching assembly 23 opens the communication between the pressure relief cavity 245 and the second water inlet cavity 244, at this time the water in the second water inlet cavity 244 flows to the pressure relief cavity 245, as long as the communication area of the first water inlet cavity 241 and the second water inlet cavity 244 is smaller than that of the second water inlet cavity 244 and the pressure relief cavity 245, the water loss rate of the second water inlet cavity 244 can be greater than the water supply rate, resulting in a decrease in the water pressure in the second water inlet cavity 244. In this way, the sealing assembly 243 is subjected to a greater water pressure on the side of the first water inlet cavity 241, and the sealing assembly 243 opens the communication between the first water inlet cavity 241 and the water outlet flow channel 242 under the action of the first water inlet cavity 241.
[0041] From the above analysis, it can be seen that the switching assembly 23 does not need to directly drive the sealing assembly 243 to move to realize the opening and closing of the water, but only needs to communicate or separate the second water inlet cavity 244 and the pressure relief cavity 245. Because the communication area of the second water inlet cavity 244 and the pressure relief cavity 245 is only required to be greater than that of the first water inlet cavity 241 and the second water inlet cavity 244, the opening of the water can be realized. Therefore, the distance that the switching assembly 23 needs to move is relatively small, and if the switching assembly 23 directly drives the sealing assembly 243 to move, the travel of the sealing assembly 243 is obviously larger considering the water flow, so the mode of the present embodiment of not directly driving the sealing assembly 243 to move through the switching assembly 23 further reduces the movement travel of the switching assembly 23.
[0042] In the embodiment, the switching assembly 23 comprises a reciprocating assembly 231 abutting against the swing member 22, and a switching shaft assembly 232 reversely matched with the reciprocating assembly 231; the swing member 22 drives the reciprocating assembly 231 to move along a first direction between a first position and a second position, and the reciprocating assembly 231 drives the switching shaft assembly 232 to move along a second direction between a third position and a fourth position. The first direction is the axial direction of the reciprocating assembly 231, the second direction is the axial direction of the switching shaft assembly 232, and the first direction and the second direction are perpendicular. During the movement of the reciprocating assembly 231 from the first position to the second position, the force generated by the reciprocating assembly 231 drives the switching shaft assembly 232 to move from the third position to the fourth position, thereby achieving the purpose of driving the switching shaft assembly 232 to move by the reciprocating assembly 231.
[0043] Specifically, the switching shaft assembly 232 comprises a switching shaft 2321, a sealing ring 2322 arranged on the side wall of the switching shaft 2321, and a first reset spring 2323 sleeved on the outer wall of the switching shaft 2321, and one end of the first reset spring 2323 away from the switching shaft 2321 abuts against the valve body 24 to form a fixed end; when the switching assembly 23 is in the water-stopping position, the reciprocating assembly 231 is in the second position, the switching shaft assembly 232 is in the fourth position, the sealing ring 2322 seals the communication between the pressure relief cavity 245 and the second water inlet cavity 244, and the first reset spring 2323 accumulates elastic reset force under pressure; when the switching assembly 23 is in the water-opening position, the reciprocating assembly 231 is in the first position, the switching shaft assembly 232 is driven by the first reset spring 2323 to be in the third position, and the sealing ring 2322 opens the communication between the pressure relief cavity 245 and the second water inlet cavity 244.
[0044] In the embodiment, the valve body 24 further comprises a water distribution body 247 fixed in the outer shell 246; the pressure relief cavity 245 is arranged in the water distribution body 247, and the switching shaft 2321 is partially inserted into the water distribution body 247. The relative movement between the switching shaft 2321 and the water distribution body 247 can open or seal the communication between the pressure relief cavity 245 and the second water inlet cavity 244.
[0045] In addition, the switching shaft 2321 is connected with a ball head 2324 at an end away from the water distribution body 247, and the reciprocating assembly 231 is reversely matched with the ball head 2324 through a slope.
[0046] The reciprocating motion assembly 231 in this embodiment is a ball pen switching structure, that is, the high position and the low position are switched by repeated pressing to achieve the effect of reciprocating motion. The high position is the first position, and the low position is the second position. When moving from the high position to the low position, the reciprocating motion assembly 231 and the switching shaft assembly 232 top and resist the acting force, which can drive the switching shaft assembly 232 to move from the third position to the fourth position. When the reciprocating motion assembly 231 moves from the low position to the high position, the top and resistance force is small, and the switching shaft assembly 232 can return to the third position from the fourth position under the action of the first return spring 2323. Therefore, the reciprocating motion assembly 231 includes a pressing head 2311, a pressing upper seat 2312, a fixed base 2313, a sliding piece 2314 and a push rod 2315; the pressing head 2311 is used for receiving the acting force of the swing piece 22 to drive the pressing upper seat 2312 to move towards the sliding piece 2314 to drive the sliding piece 2314 to rotate a fixed angle around its own axis, so that the sliding piece 2314 has a first relative position and a second relative position with the fixed base 2313; the fixed base 2313 is provided with a first limiting surface and a second limiting surface at different heights; when the sliding piece 2314 is located at the first relative position with the fixed base 2313, the sliding piece 2314 is limited by the first limiting surface, and when the sliding piece 2314 is located at the second relative position with the fixed base 2313, the sliding piece 2314 is limited by the second limiting surface; the sliding piece 2314 is fixedly connected with the push rod 2315, and the push rod 2315 is provided with an inclined surface 23151 which is reversely matched with the switching shaft assembly 232.
[0047] To realize that the pressing upper seat 2312 drives the sliding piece 2314 to rotate a fixed angle around its own axis, a side of the pressing upper seat 2312 towards the sliding piece 2314 is provided with a ratchet 23121 along the circumference, and a side wall of the sliding piece 2314 is provided with a ratchet block 23141 along the circumference; the pressing upper seat 2312 drives the sliding piece 2314 to rotate relative to the fixed base 2313 through the matching of the ratchet 23121 and the ratchet block 23141.

[0049] Finally, the swing member 22 is a lever, one end of which is an axial swing fulcrum, and the key 21 acts on the lever through a top abutting member 211.
