The pressing valve cartridge 100 has a simple structure and is easy to assemble.

Referring to fig. 2, 3 and 4, the housing 110 is substantially cylindrical, and the housing 110 has accommodating cavities 111 penetrating through two opposite ends of the housing 110. The receiving cavity 111 is used for receiving the operating member 130, the fixing seat assembly 160, the water sealing member 180 and the water inlet valve body 150, so that the casing 110 can provide protection for the operating member 130, the fixing seat assembly 160, the water sealing member 180 and the water inlet valve body 150.

The control member 130 extends into the receiving cavity 111 and is connected to the inlet valve body 150. In this embodiment, the control member 130 includes a pressing portion 131 and a rotating portion 133, the rotating portion 133 penetrates through one end of the accommodating cavity 111 and is connected to the water inlet valve body 150, and the rotating portion 133 can rotate relative to the housing 110. The rotating portion 133 is provided with an installation hole 1331, and the installation hole 1331 is used for penetrating the pressing portion 131, that is, the rotating portion 133 is arranged around the pressing portion 131. The pressing portion 131 protrudes from the mounting hole 1331 and can be pressed in the axial direction of the mounting hole 1331. In the present embodiment, the pressing portion 131 and the rotating portion 133 move independently from each other without interference. For example, the pressing portion 131 can be pressed in the axial direction of the mounting hole 1331 by an external force, and the rotating portion 133 can be rotated about the axial direction of the mounting hole 1331 with respect to the housing 110 by an external force.

In the embodiment, as shown in fig. 3, the pressing portion 131 can drive the push rod 170 to move toward the water sealing member 180 under the action of an external force and to be matched with the water sealing member 180, and the push rod 170 maintains the current matching relationship with the water sealing member 180, at this time, the water cannot be discharged by pressing the valve core 100. As shown in fig. 4, the pressing portion 131 can move away from the water sealing member 180 under the action of an external force, and the push rod 170 can be separated from the water sealing member 180, so as to press the valve cartridge 100 to discharge water.

In one embodiment, the control process of the push rod 170 by the pressing portion 131 can be realized by a ball-point pen bouncing structure, so that the current position can be maintained after the pressing portion 131 is pressed. For example, the operating member 130 further includes an engaging portion 135, the engaging portion 135 is received in the rotating portion 133 and connected to a side of the pressing portion 131 facing the accommodating cavity 111, and when the pressing portion 131 moves toward the water sealing member 180 along the axial direction of the mounting hole 1331 under an external force, the engaging portion 135 also moves along with the pressing portion 131. Meanwhile, the matching portion 135 is connected to the push rod 170, so as to drive the push rod 170 to move toward the water sealing member 180.

Further, a guide groove 1333 is provided at the inner side of the rotating portion 133, and a guide block 1351 is provided at the outer circumference of the fitting portion 135. During the movement of the fitting portion 135 with the pressing portion 131, the guide block 1351 is selectively moved along the guide groove 1333 to be disengaged from the guide groove 1333 (refer to a ball-point pen bouncing structure). In the process that the engaging portion 135 moves along with the pressing portion 131, the first state that the guide block 1351 is received in the guide slot 1333 and the second state that the guide block 1351 is separated from the guide slot 1333 are included, and in the first state and the second state, the position of the guide block 1351 is limited by the rotating portion 133, so that the pressing portion 131 can maintain the current position.

In this embodiment, the pressing valve core 100 further includes a first elastic member 120, and the first elastic member 120 may be a spring, an elastic sheet, or other structures having elastic deformation capability. The first elastic member 120 is sleeved on the pressing portion 131, a protrusion (not shown) is disposed on an outer peripheral wall of the pressing portion 131, and the first elastic member 120 abuts between the protrusion and the rotating portion 133. The elastic deformation direction of the first elastic member 120 is substantially the same as the movement direction of the pressing part 131.

The push rod 170 is substantially rod-shaped, and one end of the push rod 170 is connected to the operating member 130. In this embodiment, the push rod 170 is connected to the pressing portion 131 through the fitting portion 135. In other embodiments, the push rod may be directly connected to the pressing portion 131. The pressing portion 131 can drive the push rod 170 to move along the axial direction of the installation hole 1331 when being acted by external force. Further, when the push rod 170 is acted by an external force toward the water sealing member 180, the push rod 170 moves toward the water sealing member 180 along the axial direction of the installation hole 1331, and the push rod 170 can be engaged with the water sealing member 180, thereby preventing water from being discharged by pressing the valve cartridge 100. When the push rod 170 is acted by an external force towards the pressing portion 131, the push rod 170 moves along the axial direction of the mounting hole 1331 in a direction away from the water sealing member 180, and the push rod 170 can be separated from the water sealing member 180, so that the water outlet for pressing the valve core 100 is opened.

In this embodiment, putter 170 includes a club head 171 and a shaft 173, club head 171 being connected to shaft 173, and club head 171 having a radial dimension greater than the radial dimension of shaft 173.

The first fixing seat 161, the sealing gasket 163 and the second fixing seat 165 are used for positioning the push rod 170, so as to define the moving direction of the push rod 170, so that the push rod 170 can move along the axial direction of the mounting hole 1331.

In this embodiment, the first fixing base 161 is provided with a first positioning hole 1611, the second fixing base 165 is provided with a second positioning hole 1651 communicated with the first positioning hole 1611, and the push rod 170 passes through the first positioning hole 1611 and the second positioning hole 1651. The first positioning hole 1611, the second positioning hole 1651 and the mounting hole 1331 are coaxially disposed, so that when the pressing portion 131 moves along the axial direction of the mounting hole 1331, the pushing rod 170 can be driven to move along the axial direction of the first positioning hole 1611 and the axial direction of the second positioning hole 1651.

In this embodiment, the rod 173 of the pushing rod 170 passes through the first positioning hole 1611 and the second positioning hole 1651. The radial dimension of the rod 173 is smaller than the dimension of the first positioning hole 1611 and the dimension of the second positioning hole 1651, so that the rod 173 can pass through the first positioning hole 1611 and the second positioning hole 1651. Meanwhile, the radial dimension of the head 171 is larger than the dimensions of the first positioning hole 1611 and the second positioning hole 1651, so that the head 171 cannot pass through the first positioning hole 1611 and the second positioning hole 1651. Since the radial dimension of the head 171 is larger than the dimension of the first positioning hole 1611 and the dimension of the second positioning hole 1651, the stroke of the push rod 170 in the axial direction of the first positioning hole 1611 can be restricted. If the first positioning hole 1611 and the second positioning hole 1651 are both circular holes, the size of the first positioning hole 1611 is the diameter of the circular hole of the first positioning hole 1611, and the size of the second positioning hole 1651 is the diameter of the circular hole of the second positioning hole 1651. If the first positioning hole 1611 and the second positioning hole 1651 are square or polygonal holes, the first positioning hole 1611 has a size of the maximum diameter of a sphere that can pass through the first positioning hole 1611, and the second positioning hole 1651 has a size of the maximum diameter of a sphere that can pass through the second positioning hole 1651.

In the present embodiment, the gasket 163 includes a main body 1631 and a protrusion 1633, and the protrusion 1633 is connected to the main body 1631. The main body 1631 is disposed between the first fixing seat 161 and the second fixing seat 165, and the protruding portion 1633 is located in the second positioning hole 1651. The protrusion 1633 is located in the second positioning hole 1651 to enhance the connection between the sealing gasket 163 and the second fixing seat 165. Further, the gasket 163 is provided with a through hole (not shown) penetrating the main body 1631 and the protrusion 1633, the through hole being coaxially provided with the first positioning hole 1611 and the second positioning hole 1651, and the push rod 170 passes through the first positioning hole 1611 and the second positioning hole 1651 as well as the through hole. Protrusion 1633 is located between push rod 170 and second fixing seat 165, and protrusion 1633 can fill the gap between push rod 170 and second positioning hole 1651 to fix the position of push rod 170, and prevent push rod 170 from shifting relative to the axis of the through hole during the movement. In addition, the protruding portion 1633 is located in the second positioning hole 1651, so that the sealing effect of water inflow can be enhanced, and water entering the pressing valve core 100 can be prevented from leaking out through the second positioning hole 1651.

The second fixing seat 165 includes a superimposed portion 1653 and a circumferential side portion 1655, the circumferential side portion 1655 is connected to a circumferential edge of the superimposed portion 1653 and extends in an axial direction of the superimposed portion 1653, the circumferential side portion 1655 is connected to the water inlet valve body 150 to form the water inlet chamber 101, and water entering the pressure valve core 100 via the water inlet valve body 150 can be accumulated in the water inlet chamber 101. Further, a second positioning hole 1651 is opened in the overlap portion 1653, and the peripheral side portion 1655 and the first fixing seat 161 are respectively located on both sides of the overlap portion 1653.

Referring to fig. 3, the pressing valve element 100 further includes a second elastic element 140, and the second elastic element 140 may be a spring, a leaf spring, or other structures with elastic deformation capability. In this embodiment, the first fixing seat 161 is provided with a limiting boss 1613 surrounding the inner wall of the first positioning hole 1611, the limiting boss 1613 protrudes toward the axial direction of the first positioning hole 1611, and the second elastic element 140 is provided between the operating element 130 and the limiting boss 1613. Further, the second elastic member 140 is sleeved on the rod body 173 of the putter 170 and located between the limit boss 1613 and the rod head 171. The elastic deformation direction of the second elastic member 140 is substantially the same as the moving direction of the pressing part 131. When the push rod 170 moves towards or away from the water sealing member 180, the distance between the rod head 171 and the limiting boss 1613 changes, and an external force action of the push rod 170 towards the pressing portion 131 can be provided through the deformation of the second elastic member 140, so that the separation of the rod body 173 and the water sealing member 180 is realized.

In the present embodiment, the pressing valve core 100 has two operating states, and the first operating state of the pressing valve core 100 is that the push rod 170 maintains the matching relationship with the water sealing member 180, and water cannot flow out from the pressing valve core 100. The second working state of the pressing valve core 100 is that the push rod 170 and the water sealing member 180 are separated, and the pressing valve core 100 discharges water.

Specifically, when the pressing valve core 100 is in the first working state (as shown in fig. 3), the second elastic element 140 maintains the compression deformation state, and the rod 173 cooperates with the water sealing element 180, so that water cannot flow out from the pressing valve core 100. At this time, the guide block 1351 of the pressing portion 131 moving to the engaging portion 135 is disengaged from the guide groove 1333, so that the guide block 1333 is held by the rotating portion 133 and does not move along the guide groove 1333, so as to maintain the engaging relationship between the push rod 170 and the water sealing member 180 and maintain the pressing valve cartridge 100 in the first working state. When the pressing valve core 100 is in the second working state (as shown in fig. 4), the compression deformation state of the second elastic member 140 is released, and an external force is provided to the push rod 170 toward the pressing portion 131, the push rod 170 moves away from the water sealing member 180 under the external force, the rod 173 of the push rod 170 separates from the water sealing member 180 along with the release of the compression deformation state of the second elastic member 140, and water can be discharged by pressing the valve core 100. In this embodiment, since the rotating portion 133 is kept unchanged, the second elastic member 140 releases the compression deformation state and the pressing portion 131 is displaced relative to the rotating portion 133 along the axial direction of the mounting hole 1331, so that the first elastic member 120 between the pressing portion 131 and the rotating portion 133 is forced to be compressed into the compression deformation state. When the forces between the first elastic member 120 and the second elastic member 140 reach a balance, the position of the rod 173 is relatively fixed to maintain the second working state of the pressing valve core 100.

The inlet valve body 150 is disposed in the receiving cavity 111 and connected to the control member 130. The inlet valve body 150 is provided with an outlet 151 and an inlet 152. In an embodiment, the inlet valve body 150 is connected to the operating member 130 and the fixing seat assembly 160, and accordingly, the inlet valve body 150 includes a connecting seat 153, the connecting seat 153 includes a base 1531, a first connecting portion 1533 and a second connecting portion 1535, and the first connecting portion 1533 and the second connecting portion 1535 are disposed at the base 1531 at intervals. In this embodiment, the first connection portion 1533 and the second connection portion 1535 are connected to a side of the base 1531 facing the second fixing base 165, the first connection portion 1533 is connected to the operating member 130, the second connection portion 1535 is connected to the peripheral portion 1655, the water inlet cavity 101 is formed by the second connection portion 1535 and the peripheral portion 1655, and the water inlet cavity 101 is communicated with the water inlet 152.

The first connecting portion 1533 is a sidewall disposed around the periphery of the base 1531, the first connecting portion 1533 is connected to the rotating portion 133, and the rotating portion 133 drives the connecting seat 153 to rotate together with the housing 110 when rotating relative to the housing 110. The second connection portion 1535 is a sidewall connected to the base 1531, and the second connection portion 1535 is spaced apart from the first connection portion 1533. Further, the water outlet 151 is disposed on the base 1531 and is communicated with the water inlet chamber 101, so that water in the water inlet chamber 101 can be discharged through the water outlet 151.

In an embodiment, the inlet valve body 150 further includes a first inlet 157 and a second inlet 159, and the first inlet 157 is connected to the base 1531. When the connection base 153 rotates with the rotation part 133, the first water inlet member 157 rotates with the connection base 153 with respect to the second water inlet member 159. The first water inlet member 157 is provided with a water inlet 152, and the water inlet 152 is communicated with the water inlet cavity 101 so as to realize water inlet in the water inlet cavity 101. It should be noted that the water outlet 151 of the water inlet valve body 150 also penetrates the first water inlet member 157 and the second water inlet member 159 at the same time, so that the water in the water inlet chamber 101 is discharged from the valve core 100 through the water outlet 151.

Referring to fig. 5, the second water inlet member 159 is provided with a first water inlet 1591 and a second water inlet 1593 at an interval, and when the rotating portion 133 drives the first water inlet member 157 to rotate relative to the second water inlet member 159, the first water inlet member 157 can selectively block at least one of the first water inlet 1591 and the second water inlet 1593. The first water inlet 1591 and the second water inlet 1593 may be connected to different external water sources, for example, the first water inlet 1591 and hot water, respectively, to implement the inflow of hot water; the second inlet 1593 is connected to cold water to allow cold water to enter.

For example, as shown in fig. 6, the first water inlet 157 covers the first water inlet 1591 by rotating the rotating part 133, the water inlet 152 communicates with the second water inlet 1593, and at this time, the water entering the water inlet valve body 150 is cold water and the water outlet valve body 150 discharges the cold water.

The water sealing member 180 is arranged between the water inlet valve body 150 and the second fixing seat 165, the water sealing member 180 is provided with a pressure relief opening 181, and the pressure relief opening 181 is communicated with the water outlet 151. The water seal 180 includes a main body 183 and an extension 185. The pressure relief port 181 penetrates the body 183 and the extension 185, and the extension 185 is located in the water outlet 151. Further, when an external force acts on the pressing portion 131, the matching relationship between the push rod 170 and the water sealing member 180 is that the push rod 170 is driven to extend into or withdraw from the pressure relief opening 181. If the push rod 170 extends into the pressure relief opening 181 (i.e., the valve core 100 is pressed to be in the first working state, the push rod 170 is matched with the water sealing member 180), the push rod 170 and the water sealing member 180 are matched to jointly seal the water outlet 151, and water in the water inlet cavity 101 cannot flow out from the valve core 100; if the push rod 170 exits the pressure relief opening 181 (i.e. the push rod 170 is separated from the water sealing member 180 when the valve core 100 is pressed to be in the second working state), the push rod 170 exits the pressure relief opening 181 of the water sealing member 180, the water outlet 151 is communicated with the water inlet cavity 101 through the pressure relief opening 181, and water in the water inlet cavity 101 flows out from the valve core 100.

In the present embodiment, the water sealing member 180 is disposed between the second fixing base 165 and the second connecting portion 1535, that is, the water sealing member 180 is disposed in the water inlet chamber 101. Further, the water seal 180 divides the water inlet chamber 101 into a first water inlet chamber 1011 and a second water inlet chamber 1013, and the first water inlet chamber 1011 is communicated with the water inlet 152. The water seal 180 is provided with a communication hole 187, and the communication hole 187 communicates the first and second

water inlet chambers

1011 and 1013 so that water passing through the water inlet 152 can enter the first and second

water inlet chambers

1011 and 1013.

When the valve body 100 is pressed to operate, external water enters the first water inlet chamber 1011 from the water inlet 152, and enters the second water inlet chamber 1013 through the first water inlet chamber 1011 and the communication hole 187 in sequence. If the pressing valve core 100 is in the first working state (as shown in fig. 3), the push rod 170 extends into the pressure relief opening 181, water entering the second water inlet cavity 1013 cannot flow out through the pressure relief opening 181 and the water outlet 151, the water pressure of the second water inlet cavity 1013 is greater than the water pressure of the first water inlet cavity 1011, the water sealing member 180 seals the water outlet 151 under the action of the water pressure of the second water inlet cavity 1013, and at this time, the pressing valve core 100 cannot flow out. If the pressing valve core 100 is in the second working state (as shown in fig. 4), the push rod 170 exits the pressure relief opening 181, the water pressure of the second water inlet cavity 1013 is instantaneously lower than the water pressure of the first water inlet cavity 1011, the water outlet 151 is opened by the water sealing member 180, at this time, the water entering the first water inlet cavity 1011 flows out through the water outlet 151, the water entering the second water inlet cavity 1013 flows out through the pressure relief opening 181 and the water outlet 151, and therefore the water outlet of the pressing valve core 100 is achieved.

In the embodiment of the present invention, the pressing valve core 100 further includes a base 190, and the base 190 is connected to one side of the second water inlet 159 away from the operation member 130 and is connected to the housing 110. Through the base 190, the position of the water inlet valve body 150 in the accommodating cavity 111 can be limited, so that the structure of the pressing valve core 100 is more compact.

The utility model provides a press down case 100 can control push rod 170 through pressing according to splenium 131, can control the shutoff of water sealing piece 180 or open delivery port 151. If the water outlet 151 is opened by the water sealing member 180, water can be discharged by pressing the valve core 100; if the water sealing piece 180 seals the water outlet 151, water cannot be discharged by pressing the valve core 100. Also, the ratio between the flow rate of hot water flowing through the first water inlet 1591 and the flow rate of cold water flowing into the water inlet 152 through the second water inlet 1593 can be controlled by rotating the rotating part 133 to provide water of a proper temperature.
