Generally, the ballpoint pen ratchet structure includes a pressing rod, a moving ratchet and a fixed ratchet; the pressing rod moves up and down in the axial direction, and the moving ratchet needs to move up and down in the axial direction and rotate around the axis; the fixed ratchet is generally arranged on the housing to provide the high and low position limits of the moving ratchet; the working spring abuts against the moving ratchet. Since the movement stroke of the ballpoint pen structure is relatively large, when driving the pressing valve core switch through a button, a button with the same large stroke is also required, so that the user has a relatively large stroke and poor feel when switching.

[0012] In a preferred embodiment: A ball head is connected to one end of the switching shaft away from the water distributor, and the reciprocating motion component forms a commutation cooperation with the ball head through an inclined surface.

[0013] In a preferred embodiment: The reciprocating motion component includes a pressing head, a pressing upper seat, a fixed base, a sliding member and a push rod;

[0015] In a preferred embodiment: The side of the pressing upper seat facing the sliding member is provided with ratchet teeth along the circumferential direction, and the side wall of the sliding member is provided with ratchet blocks at intervals along the circumferential direction; the pressing upper seat drives the sliding member to rotate relative to the fixed base through the cooperation of the ratchet teeth and the ratchet blocks.

[0016] In a preferred embodiment: Along the radial direction, the switching shaft assembly is disposed outside the reciprocating motion assembly.

[0017] In a preferred embodiment: Along the axial direction, the sealing assembly is disposed below the reciprocating motion assembly.

[0018] In a preferred embodiment: The distance between the acting point of the key and the swinging member and the swinging fulcrum of the swinging member is S1, and the distance between the acting point of the swinging member and the switching assembly and the swinging fulcrum of the swinging member is S2, where S1 < S2.

[0023] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0024] The present invention provides a push-button switch valve core. By acting on different positions of the swinging member with the key and the switching assembly, the stroke brought by the user pressing the key can be amplified by the swinging member, achieving the effect of a micro switch, that is, the user only needs to press the key to bring a relatively small stroke, which can be amplified by the swinging member into a relatively large stroke of the switching assembly to complete the entire switching process.

[0025] The present invention provides a push-button switch valve core. When the switching assembly switches, as long as the second water inlet cavity and the pressure relief cavity are connected or separated, the water pressure in the second water inlet cavity can be changed, so as to drive the sealing assembly to move by the water pressure to realize opening and stopping the water. Therefore, the switching assembly does not need to directly drive the sealing assembly, and thus the required switching stroke of the switching assembly is further reduced.

[0026] The present invention also provides a shower controller. A part of the pressing switch valve core is placed in the control base, and the rest is exposed outside the control base to reduce the volume occupied by the pressing switch valve core in the control base. In this way, on the premise of not sacrificing the flow rate, as many switch valve cores as possible can be installed in the same-sized control base, thereby increasing the number of water outlet terminals that the shower controller can control and enhancing the functions of the shower controller.

[0036] In order to make the technical solutions and features of the present invention clearer, the following further elaborates on the present invention in detail in combination with the drawings and specific examples. It should be understood that these examples are only used to illustrate the present invention and not to limit the scope of the present invention. After reading the present invention, various equivalent modifications made by those skilled in the art to the present invention fall within the scope defined by the appended claims of this application.

[0037] Reference Figures 1 - 9, this embodiment provides a shower device, including a water outlet terminal and a shower controller 1, as well as a pipeline connecting the water outlet terminal and the shower controller 1. By means of the push-switch valve core 2 installed on the shower controller 1, the corresponding water outlet terminal can be controlled to discharge water or stop water.

[0038] In order to be able to install a sufficient number of push-switch valve cores 2 so that the shower controller 1 can control more water outlet terminals, the shower controller 1 in this embodiment includes a control base 11 and four push-switch valve cores 2 as described above; a part of the push-switch valve core 2 is placed in the control base 11, that is Figure 3 the dotted part in the figure, and the rest is exposed outside the control base 11 to reduce the volume occupied by the push-switch valve core 2 in the control base 11. In this way, a part of the push-switch valve core 2 is installed in the control base 11, so only this part will occupy the space inside the control base 11. Therefore, compared with the scheme of placing the push-switch valve core 2 entirely inside the control base 11, the volume occupied by the push-switch valve core 2 on the control base 11 is greatly reduced. In this way, more push-switch valve cores 2 can be placed without reducing the volume of the push-switch valve core 2, so as to install as many push-switch valve cores 2 as possible without sacrificing the flow rate to control more water outlet terminals. In this embodiment, the four push-switch valve cores 2 respectively control four water outlet terminals.

[0039] The push-switch valve core 2 in this embodiment can reduce the pressing stroke required by the user during operation, so as to achieve a better operation feel. For this purpose, the push-switch valve core 2 includes: a button 21, a swing member 22, a switching component 23, and a valve body 24. The button 21 is linked with the switching component 23 through the swing member 22 to drive the switching component 23 to switch between the open-water position and the water-stop position. The distance between the acting point of the button 21 and the swing member 22 and the swing fulcrum of the swing member 22 is S1, and the distance between the acting point of the swing member 22 and the switching component 23 and the swing fulcrum of the swing member 22 is S2, and S1 < S2: Since the acting point of the button 21 and the swing member 22 is closer to the swing fulcrum, in the case of the same central angle of swing, the stroke of the button 21 is relatively small, while the stroke of the switching component 23 is relatively large. Thus, it realizes the amplification of the stroke brought by the user pressing the button 21 by the swing member 22, achieving the effect of a microswitch, that is, the user only needs to press the button 21 to bring a relatively small stroke, which can be amplified by the swing member 22 into a relatively large stroke of the switching component 23 to complete the entire switching process.

[0040] To achieve the opening and stopping of water flow by pressing the switch valve core 2, the valve body 24 has a first water inlet chamber 241, a water outlet flow channel 242, a sealing assembly 243 and a housing 246 arranged between the first water inlet chamber 241 and the water outlet flow channel 242. A second water inlet chamber 244 is formed between the sealing assembly 243 and the housing 246. The first water inlet chamber 241 communicates with the second water inlet chamber 244, and the acting area of the second water inlet chamber 244 and the sealing assembly 243 is larger than the acting area of the first water inlet chamber 241 and the sealing assembly 243. The valve body 24 further includes a pressure relief chamber 245. When the switching assembly 23 is in the water stopping position, the switching assembly 23 seals the connection between the pressure relief chamber 245 and the second water inlet chamber 244. At this time, water flow only exists in the first water inlet chamber 241 and the second water inlet chamber 244. Since the acting area of the second water inlet chamber 244 and the sealing assembly 243 is larger than the acting area of the first water inlet chamber 241 and the sealing assembly 243, the sealing assembly 243 is subjected to a greater acting force of the water on the second water inlet chamber 244 side. Under the action of the water in the second water inlet chamber 244, the sealing assembly 243 seals the connection between the first water inlet chamber 241 and the water outlet flow channel 242, thus completing the water stopping. When the switching assembly 23 is in the water opening position, the switching assembly 23 opens the connection between the pressure relief chamber 245 and the second water inlet chamber 244. At this time, the water in the second water inlet chamber 244 flows into the pressure relief chamber 245. As long as the conduction area between the first water inlet chamber 241 and the second water inlet chamber 244 is set to be smaller than the conduction area between the second water inlet chamber 244 and the pressure relief chamber 245, the water loss speed of the second water inlet chamber 244 can be made greater than the water replenishment speed, resulting in a decrease in the water pressure in the second water inlet chamber 244. In this way, the sealing assembly 243 is subjected to a greater water pressure on the first water inlet chamber 241 side. Under the action of the first water inlet chamber 241, the sealing assembly 243 opens the connection between the first water inlet chamber 241 and the water outlet flow channel 242.

[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 achieve the opening and stopping of water flow. Instead, it only needs to conduct or separate the second water inlet chamber 244 and the pressure relief chamber 245. Also, since the conduction area between the second water inlet chamber 244 and the pressure relief chamber 245 only needs to be larger than the conduction area between the first water inlet chamber 241 and the second water inlet chamber 244 to achieve the opening of water flow. Therefore, the distance that the switching assembly 23 needs to move is relatively small. If the switching assembly 23 directly drives the sealing assembly 243 to move, considering the water flow rate, the moving stroke of the sealing assembly 243 is significantly larger. Therefore, in this embodiment, the method of not directly driving the sealing assembly 243 to move by the switching assembly 23 further reduces the moving stroke of the switching assembly 23.

[0042] In this embodiment, the switching component 23 includes a reciprocating motion component 231 that abuts against the swinging member 22, and a switching shaft component 232 that is commutatively matched with the reciprocating motion component 231; the swinging member 22 drives the reciprocating motion component 231 to move between a first position and a second position along a first direction, and the reciprocating motion component 231 drives the switching shaft component 232 to move between a third position and a fourth position along a second direction. The first direction is the axial direction of the reciprocating motion component 231, the second direction is the axial direction of the switching shaft component 232, and the first direction and the second direction are perpendicular. During the process of the reciprocating motion component 231 moving from the first position to the second position, the acting force generated on the switching shaft component 232 will drive the switching shaft component 232 to move from the third position to the fourth position, thereby achieving the purpose of driving the switching shaft component 232 by the reciprocating motion component 231.

[0043] Specifically, the switching shaft component 232 includes a switching shaft 2321, a sealing ring 2322 provided on the side wall of the switching shaft 2321, and a first return spring 2323 sleeved on the outer wall of the switching shaft 2321. One end of the first return spring 2323 away from the switching shaft 2321 abuts against the valve body 24 to form a fixed end; when the switching component 23 is in the water stop position, the reciprocating motion component 231 is in the second position, the switching shaft component 232 is in the fourth position, the sealing ring 2322 seals the communication between the pressure relief chamber 245 and the second water inlet chamber 244, and the first return spring 2323 is compressed to accumulate elastic restoring force; when the switching component 23 is in the hot water position, the reciprocating motion component 231 is in the first position, the switching shaft component 232 is in the third position driven by the first return spring 2323, and the sealing ring 2322 opens the communication between the pressure relief chamber 245 and the second water inlet chamber 244.

[0044] In this embodiment, the valve body 24 further includes a water distributor 247 fixed in the housing 246; a pressure relief chamber 245 is provided in the water distributor 247, and a part of the switching shaft 2321 is inserted into the water distributor 247. By the relative movement between the switching shaft 2321 and the water distributor 247, the communication between the pressure relief chamber 245 and the second water inlet chamber 244 can be opened or sealed.

[0045] In addition, a ball head 2324 is connected to one end of the switching shaft 2321 away from the water distributor 247, and the reciprocating motion component 231 forms a commutation cooperation with the ball head 2324 through an inclined surface.

[0046] In this embodiment, the reciprocating motion assembly 231 is a ballpoint pen switching structure, which realizes the switching between the high position and the low position through repeated pressing to achieve the reciprocating motion effect. 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 abut against each other to generate a 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, when the abutting force is small, the switching shaft assembly 232 can return from the fourth position to the third 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 member 2314, and a push rod 2315; the pressing head 2311 is used to receive the force of the swinging member 22 and drive the pressing upper seat 2312 to move towards the sliding member 2314, so as to drive the sliding member 2314 to rotate around its own axis by a fixed angle, so that the sliding member 2314 and the fixed base 2313 have a first relative position and a second relative position; the fixed base 2313 is provided with a first limiting surface and a second limiting surface at different heights; when the sliding member 2314 and the fixed base 2313 are in the first relative position, the sliding member 2314 is in limiting cooperation with the first limiting surface, and when the sliding member 2314 and the fixed base 2313 are in the second relative position, the sliding member 2314 is in limiting cooperation with the second limiting surface; the sliding member 2314 is fixedly connected to the push rod 2315, and the inclined surface 23151 is provided on the push rod 2315 for reverse cooperation with the switching shaft assembly 232.

[0047] To realize that the pressing upper seat 2312 drives the sliding member 2314 to rotate around its own axis by a fixed angle, the side of the pressing upper seat 2312 facing the sliding member 2314 is provided with ratchet teeth 23121 along the circumferential direction, and the side wall of the sliding member 2314 is provided with ratchet blocks 23141 at intervals along the circumferential direction; the pressing upper seat 2312 drives the sliding member 2314 to rotate relative to the fixed base 2313 through the cooperation of the ratchet teeth 23121 and the ratchet blocks 23141.

[0048] In this embodiment, the sealing assembly 243 includes a leather cup 2431, a leather cup seat 2432, and an anti-scaling spring 2433. The leather cup 2431 is fixed on the leather cup seat 2432, and the anti-scaling spring 2433 is connected between the second water inlet cavity 244 and the leather cup seat 2432. In this way, in the water-off state, the anti-scaling spring 2433 is in a pre-compressed state. When the water is turned on, under the action of the water pressure in the first water inlet cavity 241, the leather cup 2431 is driven to move, and the anti-scaling spring 2433 is compressed to accumulate elastic restoring force, opening the communication between the first water inlet cavity 241 and the water outlet channel 242.

[0049] Finally, the swinging member 22 is a lever, one end of which along the axial direction is a swinging fulcrum, and the button 21 acts on the lever through the abutting member 211.

[0050] The above is only a specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantive modification made to the present invention using this concept shall fall within the scope of infringement of the protection scope of the present invention.
