Referring to fig. 1 and 2, a valve cartridge 1000 according to an embodiment of the present invention may be used in a water outlet device to control on/off of a water path, for example, the water outlet device may be a faucet used in a kitchen or a faucet used in a shower, and the control manner may be pressing, rotating, gesture control, etc. All subsequent embodiments of the invention take pressing as an example, water is discharged by pressing once, and water is closed by pressing once again, so that the operation is simple and convenient.

Referring to fig. 3, a valve cartridge 1000 according to an embodiment of the present invention includes a housing 100, a switching seat 300, a switch 200, a spacer 410, a blocking member 420, and a valve seat 430. The switching seat 300 is disposed inside the housing 100, and as shown in fig. 6 and 7, the switching seat 300 includes a valve rod portion 310 and a switching portion 350 that are fixedly connected, for example, the valve rod portion 310 and the switching portion 350 are integrally formed or connected by a fastener. The inside of the switching part 350 defines the water passing cavity 320, and one end of the switching part 350, which faces away from the valve rod part 310, is a first end wall 351, the first end wall 351 is provided with a first water passing hole 330 and a second water passing hole 340 which are both communicated with the water passing cavity 320, the second water passing hole 340 can be one or more, and when a plurality of water passing holes are arranged along the circumferential interval of the first water passing hole 330, for example, the second water passing hole 340 is four and is uniformly arranged on the first end wall 351 at intervals. A part of the switch 200 is disposed inside the housing 100 and connected to the stem 310, and the other part is exposed from the housing 100 for easy pressing. The switch 200 is used for driving the switch base 300 to rotate. For example, once the switch 200 is pressed, the switch 200 can drive the valve rod portion 310 to rotate a predetermined angle, and since the valve rod portion 310 is fixedly connected to the switching seat 300, the valve rod rotation also drives the switching seat 300 to rotate a predetermined angle.

With continued reference to fig. 3, the housing 100 is formed with a structure similar to a step, the spacer 410 is disposed in the housing 100 and positioned in abutment with the step of the housing 100, the spacer 410 is provided with a pressure relief channel 411, and one end facing the switch seat 300 is provided with a second end wall 417, the second end wall 417 is provided with a third water through hole 412, and the second end wall 417 is in contact fit with the first end wall 351. A blocking member 420 is arranged in the housing 100, the blocking member 420 is slidably connected to a side of the spacer 410 facing away from the second end wall 417 and defines a pressure relief chamber 401 with the spacer 410, and the blocking member 420 is provided with a first water passage 421 and a pilot passage 4251. The valve seat 430 comprises an annular structure 433 and an outer valve body 434, the outer valve body 434 is connected with the housing 100, the outer valve body 434 is provided with a water inlet 435, the annular structure 433 is arranged inside the outer valve body 434, a water outlet channel 432 is defined inside the annular structure 433, a water inlet channel 431 is defined between the annular structure 433 and the outer valve body 434, and the water inlet channel 431 is communicated with the water inlet 435. The water inlet passage 431 is connected to the pressure relief chamber 401 through a pilot passage 4251, that is, water enters the water inlet passage 431 from the water inlet 435 and then enters the pressure relief chamber 401 through the pilot passage 4251. The pressure relief chamber 401 can communicate with the water passing chamber 320 through the pressure relief passage 411, and the water passing chamber 320 communicates with the water outlet passage 432 through the first water passing hole 330, the third water passing hole 412, the first water passing passage 421 and the third water passing hole 412.

Wherein the switch base 300 has a first position and a second position, and the switching between the first position and the second position is achieved by pressing the switch 200. When the switch base 300 is located at the first position, for example, the position shown in fig. 4, the pressure relief cavity 401 is communicated with the water passing cavity 320 through the pressure relief channel 411, the second water passing hole 340, i.e., water passes through the water inlet 435, the water inlet 431, the pilot channel 4251, the pressure relief cavity 401, the pressure relief channel 411, the second water passing hole 340, the water passing cavity 320, the first water passing hole 330, the third water passing hole 412, the first water passing channel 421, and finally enters the pressure relief channel 411. Therefore, the pressure in the water inlet channel 431 is greater than the pressure in the pressure relief chamber 401, so that the blocking member 420 moves upward, i.e. the blocking member 420 is separated from the annular structure 433, the water inlet channel 431 is directly communicated with the water outlet channel 432, and the water is discharged from the water outlet 436 of the water outlet channel 432, i.e. the water tap opens the water outlet.

When the switch 200 is pressed again, the switch base 300 is switched to the second position, for example, the position in fig. 3, the first end wall 351 can close one end of the pressure relief channel 411, that is, the second through hole 4133 and the pressure relief channel 411 are not communicated, at this time, the water in the pressure relief cavity 401 cannot enter the water passing cavity 320 through the pressure relief channel 411, that is, the water in the pressure relief cavity 401 cannot be discharged. At this time, the pressure of the water inlet channel 431 is lower than that of the pressure relief chamber 401, so that the blocking piece 420 moves down to abut against the annular structure 433, thereby closing the water outlet channel 432, i.e. the faucet is closed.

It can be understood that a plurality of second water passing holes 340 are provided at intervals along the circumference of the first water passing hole 330, so that the one-time switch 200 is pressed, one of the second water passing holes 340 communicates with the pressure relief channel 411, and when the one-time switch 200 is pressed again, the pressure relief channel 411 is closed by the first end wall 351. The switch of the pressure discharge passage 411 is implemented by converting the linear motion of the switch 200 into the rotational motion of the switching base 300. The large-caliber valve is controlled to be opened and closed by smaller energy, the large-caliber valve is not influenced by water pressure, the pressing is smoother, the switching is more labor-saving, the water inlet channel 431 is slowly opened, and the water hammer phenomenon can be well eliminated. The position of the switching seat 300 is basically not affected by the fluctuation of the water pressure, so that the phenomenon that the abrasion between the switching seat 300 and the spacer 410 is aggravated due to the fluctuation of the water pressure is effectively improved, and the reliability of the switching seat 300 for controlling the switch of the pressure relief channel 411 is improved.

Referring to fig. 2, in the embodiment of the present invention, the switch 200 includes a button 210 and a rotary base 220, the rotary base 220 is disposed in the housing 100, the rotary base 220 is provided with a limit cavity 222, and a valve stem portion 310 is inserted in the limit cavity 222, so that the rotary base 220 can drive the valve stem portion 310 to rotate. For example, the valve stem portion 310 may have a polygonal cross-section, and the check cavity 222 may have a polygonal cross-section, or other shape that is capable of cooperating with the valve stem portion 310 such that the rotary seat 220 is capable of driving the valve stem portion 310 to rotate. The button 210 and the rotary base 220 are connected and part of the structure is arranged outside the casing 100. The button 210 is provided with internal threads, so that the switch of the faucet can be conveniently connected with the button 210, and the universality is improved. The button 210 is provided with a plurality of first fitting columns 211, the plurality of first fitting columns 211 are arranged along the circumferential direction of the button 210 at intervals, the rotating seat 220 is provided with a plurality of second fitting columns 221, and the plurality of second fitting columns 221 are arranged along the circumferential direction of the rotating seat 220 at intervals. The housing 100 is provided with a plurality of grooves (not shown), the first engaging posts 211 and the second engaging posts 221 are respectively engaged with the grooves, and the grooves function as guiding and limiting. The opposite ends of the first and second engaging

posts

211 and 221 are provided with slopes, so that when the button 210 is pressed downward, the rotating base 220 is rotated by the abutting engagement of the slopes, thereby driving the valve rod portion 310 to rotate. A second elastic member 230 is disposed between the rotating seat 220 and the switching seat 300, the second elastic member 230 is a spring or elastic rubber or silica gel, and the second elastic member 230 is sleeved on the valve rod portion 310, and two ends of the second elastic member respectively abut against the rotating seat 220 and the switching portion 350, so that the rotating seat 220 can move upward or return under the action of the elastic force. By adopting the pressing structure, the automatic telescopic locking of the switch 200 can be realized in a manner similar to the pressing manner of a ball-point pen, and the pressing is smooth and reliable.

Referring to fig. 8 and 9, in the embodiment of the present invention, the spacer 410 includes a sheath 413 and a switching head 414. The sleeve body 413 is substantially in a bottle cap shape, the sleeve body 413 is provided with a second end wall 417, the second end wall 417 is recessed towards a direction away from the first end wall 351 to form a mounting portion 4131, the mounting portion 4131 is provided with an accommodating cavity, the mounting portion 4131 is provided with an opening 4132 towards the first end wall 351 and a through hole 4133 communicated with the pressure relief cavity 401, and the through hole 4133 is arranged on the bottom wall of the accommodating cavity. The switching head 414 is installed in the receiving cavity of the mounting portion 4131, and the switching head 414 forms a second water passage 4142, and the second water passage 4142 and the through hole 4133 communicate to form the pressure relief passage 411. Therefore, when the switching base 300 is at the first position, the water in the pressure relief chamber 401 can pass through the through hole 4133, the second water passing channel 4142, the second water passing hole 340 in sequence, and then enter the water passing chamber 320. When the switch base 300 is rotated to the second position, both ends of the switch head 414 respectively abut against the first end wall 351 and the mounting portion 4131, so that water is difficult to seep out from a gap between the switch head 414 and the mounting portion 4131, thereby ensuring the sealing performance of the valve core 1000, effectively reducing the water seepage and leakage of the valve core 1000, and improving the reliability of the valve core 1000.

To further increase the sealing effect, the water is prevented from entering the second water passing hole 340 from the gap between the switching head 414 and the first end wall 351. In an embodiment of the present invention, the switching head 414 has elasticity, and is made of a silicone or rubber material, and two ends of the switching head 414 respectively abut against the first end wall 351 and the bottom wall of the mounting portion 4131, so as to ensure a sealing effect between the switching head 414 and the first end wall 351, and prevent water from leaking out from between the switching head 414 and the inner wall of the accommodating cavity, thereby effectively improving the water leakage. Alternatively, referring to fig. 8 and 9, in another embodiment of the present invention, the spacer 410 further includes a first elastic member 415, two ends of the first elastic member 415 respectively abut against the bottom walls of the switching head 414 and the mounting portion 4131, and the first elastic member 415 may be a resilient component such as a spring, silicon rubber, or rubber. Taking a spring as an example, one of the installation cases may be: the switching head 414 is in a sleeve shape, the spring is arranged in the second water passing channel 4142, and two ends of the spring are respectively abutted against the inner wall of the switching head 414 and the bottom wall of the mounting part 4131.

For example, when the switching base 300 is at the first position, the boss 4141 is located in the second water passing hole 340, and the second water passing channel 4142 is communicated with the second water passing hole 340; when the switch base 300 is at the second position, the first end wall 351 and the end surface of the boss 4141 are in abutting engagement to close the second water passing channel 4142. It will be appreciated that the provision of the boss 4141 and the first end wall 351 cooperate to reduce the mating area of the first end wall 351 and the switching head 414, thereby improving the sealing when the switching head 414 and the first end wall 351 are in abutting engagement. Referring to fig. 3, in the embodiment of the present invention, the height of the switching head 414 along the vertical direction is smaller than the height of the accommodating cavity of the mounting portion 4131, so that the switching head 414 can be completely accommodated in the accommodating cavity, and the situation that the projection height of the boss 4141 is too high and the switching seat 300 is inclined is effectively avoided, so that the switching head 414 is reasonable in design and high in reliability.
