As shown in fig. 1-2 and 6-9, according to some embodiments of the present invention, the valve assembly 10 includes a sealing member 11 and a movable push rod 12, the sealing member 11 is used for opening and closing the first delivery hole 2145, the push rod 12 is connected to the sealing member 11, the push rod 12 is adapted to move under the pressing action of the driving key 51, and the movement of the push rod 12 can drive the sealing member 11 to move, so that the sealing member 11 opens the first delivery hole 2145.

Further, the valve assembly 10 further includes a first reset element 14, where the first reset element 14 is sleeved outside the push rod 12, and the first reset element 14 can drive the push rod 12 to reset, so as to drive the sealing component 11 to close the first delivery hole 2145. The valve assembly 10 can be used for controlling the opening and closing of the first feeding hole 2145, so that not only can the liquid leakage phenomenon be prevented, but also the liquid discharging rule of the first feeding hole 2145 can be controlled, and the liquid discharging requirement can be met.

Specifically, when the valve assembly 10 is in the initial state, the valve assembly 10 closes the first delivery orifice 2145; when the driving key 51 is pressed, the driving key 51 drives the valve assembly 10 to move, so that the valve assembly 10 opens the first delivery hole 2145; when the pressing action of the driving key 51 is removed, the valve assembly 10 is reset under the action of the first reset element 14, that is, the first reset element 14 drives the valve assembly 10 to move towards the initial position, so that the valve assembly 10 closes the first delivery hole 2145.

In some embodiments, the push rod 12 includes a boss 122, the boss 122 is located at one end of the push rod 12 near the first transmission structure 54, a hemispherical structure is disposed on one side of the boss 122 near the first transmission structure 51, and a tangential contact point is always formed between the first transmission structure 54 and the push rod 12 by setting one side of the boss 122 to be a hemispherical structure, so that resistance is reduced, and the push rod 12 can be smoothly pushed to move downwards by the driving key 51, so that smoothness of movement is ensured.

In some embodiments, the boss 122 has an outer diameter greater than the outer diameter of the first restoring member 14, ensuring that the first restoring member 14 abuts the boss 122, preventing the first restoring member 14 from being disengaged from the valve assembly 10.

According to some embodiments of the present invention, the sealing member 11 is detachably connected to the push rod 12, so that the valve assembly 10 is not only convenient to install in a position to be installed, but also convenient to detach and maintain.

As shown in fig. 2, in some embodiments, one of the push rod 12 and the sealing member 11 has an external thread structure 121, and the other of the push rod 12 and the sealing member 11 has an internal thread structure 1111, and the push rod 12 and the sealing member 11 are engaged by the external thread structure 121 and the internal thread structure 1111.

Specifically, one end of the push rod 12 is provided with an external thread structure 121, one end of the sealing component 11 is provided with a matched blind hole, the hole wall of the matched blind hole is provided with an internal thread structure 1111, one end of the push rod 12 is inserted into the matched blind hole, and the external thread structure 121 is matched with the internal thread structure 1111, so that the connection reliability of the push rod 12 and the sealing component 11 is ensured. Of course, the arrangement positions of the male screw structure 121 and the female screw structure 1111 may be interchanged.

As shown in fig. 1 and 2, according to some embodiments of the present invention, the sealing member 11 includes a mounting base 111, the mounting base 111 is connected with the push rod 12, a sidewall of the mounting base 111 is provided with a connection arm 112, one end of the connection arm 112 is connected with the sidewall of the mounting base 111, and the other end of the connection arm 112 extends in a direction away from a center line of the mounting base 111.

Further, the sealing member 11 further includes a sealing member 113, where the sealing member 113 is disposed on the connection arm 112, for example, the sealing member 113 may be disposed in a middle portion of the connection arm 112 in a length direction (for example, a direction perpendicular to an axis of the mounting seat 111), or may be disposed at another end of the connection arm 112 (i.e., a free end of the connection arm 112), and the sealing member 113 is configured to open and close the first delivery hole 2145.

That is, the connection between the mounting seat 111 and the sealing member 113 is realized through the connection arm 112, and by providing the connection arm 112, the sealing member 113 can be arranged at a position different from the push rod 12, that is, the arrangement position of the sealing member 113 is reasonably arranged, so that the occupied space of the valve assembly 10 in the axial direction of the push rod 12 is reduced. In addition, the mounting base 111 may be provided with a plurality of connecting arms 112, so that the plurality of sealing members 113 are connected with the mounting base 111, which is advantageous in achieving synchronous movement of the plurality of sealing members 113.

The sealing member 113 may be made of a silicone material or plastic.

In some embodiments, the number of connecting arms 112 is equal to and mates with the number of seals 113 in a one-to-one correspondence. For example, the side wall of the mounting base 111 is provided with two oppositely arranged connecting arms 112, and a free end of each connecting arm 112 is provided with a sealing member 113, so that two dispensing holes (a first dispensing hole 2145 and a second dispensing hole 2146 as described below) can be simultaneously opened and closed by using one sealing member 11.

Of course, the number of the connecting arms 112 and the sealing members 113 may be three or more, and may be specifically selected according to practical situations.

As shown in fig. 2, in some embodiments, the free end of the connecting arm 112 is provided with a positioning post 1121, and the sealing member 113 is sleeved outside the positioning post 1121. By adopting the positioning column 1121, not only the sealing member 113 can be positioned, but also the sealing member 113 can be supported, so that the sealing of the first delivery hole 2145 is prevented from being influenced by the fact that the sealing member 113 is deformed too much under force.

It should be noted that, the outer diameter of the positioning post 1121 may be smaller than the radial dimension of the first dispensing hole 2145, the sealing member 113 covers the peripheral wall of the positioning post 1121 and the end of the positioning post 1121 is exposed, or the sealing member 113 covers the peripheral wall and the end of the positioning post 1121, so that the sealing member 113 may be located between the side wall of the positioning post 1121 and the hole edge 2147 of the first dispensing hole 2145 when the first dispensing hole 2145 is closed.

Of course, the outer dimension of the positioning post 1121 may be greater than or equal to the dimension of the first delivery hole 2145, and the sealing member 113 covers the end of the positioning post 1121, so that the sealing member 113 may be located between the end of the positioning post 1121 and one side of the first delivery hole 2145 when the first delivery hole 2145 is closed.

In some embodiments, the sealing member 113 includes a sleeve 1131, a first sealing portion 1132 and a second sealing portion 1133, where the sleeve 1131 is matched with the connecting arm 112, for example, the sleeve 1131 may be sleeved on the outer side of the positioning column 1121 of the connecting arm 112, the first sealing portion 1132 and the second sealing portion 1133 are disposed on the peripheral wall of the sleeve 1131, and the first sealing portion 1132 and the second sealing portion 1133 are arranged along the axial direction of the sleeve 1131, and the first sealing portion 1132 and the second sealing portion 1133 may be matched with the hole edge 2147 of the first feeding hole 2145, so as to realize double sealing.

In some examples, the first seal 1132 surrounds the sleeve 1131, the first seal 1132 extends obliquely outward in a radial direction of the sleeve 1131, i.e., the first seal 1132 extends obliquely from a direction closer to the central axis of the sleeve 1131 to a direction away from the central axis of the sleeve 1131. During closing of the first delivery hole 2145, that is, during upward movement of the valve assembly 10 from the position shown in fig. 9 to the position shown in fig. 8, the first sealing portion 1132 is inserted into the first delivery hole 2145 and can be in interference fit with the hole edge 2147 of the first delivery hole 2145 in the radial direction, so that sealing is achieved, and the first sealing portion 1132 can also play a guiding role due to a certain inclination of the first sealing portion 1132.

As shown in fig. 1 and 2, in some examples, the second sealing portion 1133 includes a first sealing lip 11331 and a second sealing lip 11332 that are connected, the first sealing lip 11331 and the second sealing lip 11332 respectively surround the sleeve 1131, the first sealing lip 11331 extends obliquely in a radial direction of the sleeve 1131 toward the first sealing portion 1132, the second sealing lip 11332 is located between the first sealing portion 1132 and the first sealing lip 11331, and the second sealing lip 11332 extends obliquely in a radial direction of the sleeve 1131 toward the direction away from the first sealing lip 11331.

That is, the inner rings of the first sealing lip 11331 and the second sealing lip 11332 are joined and the outer rings extend in a direction away from each other, so that the second sealing portion 1133 forms a double-layer sealing structure having a V-shaped cross section.

In the process of closing the first delivery hole 2145, the valve assembly 10 is inserted into the first delivery hole 2145 by the first sealing portion 1132, and can be in interference fit with the hole edge 2147 of the first delivery hole 2145 in the radial direction, so that sealing is achieved, and the first sealing portion 1132 can also play a guiding role due to the fact that the first sealing portion 1132 has a certain inclination.

Further, after the valve assembly 10 is moved into position, the second sealing portion 1133 is abutted against a side surface of the first delivery hole 2145, specifically, the first sealing lip 11331 is engaged with a side surface of the first delivery hole 2145 (for example, a plane in which a lower end of the first delivery hole 2145 is opened), thereby achieving an end face seal.

Thus, the sealing member 113 in the present application has a double sealing function, and the valve assembly 10 can improve the reliability of sealing during the process of closing the first delivery hole 2145.

As shown in fig. 12, according to some embodiments of the present invention, the first transmission structure 54 has an actuating surface 524, where the actuating surface 524 may be slidably engaged with the valve assembly 10, and the actuating surface 524 may drive the valve assembly 10 to move during pressing of the actuating key 51, so that the valve assembly 10 opens the first delivery hole 2145.

Specifically, one end of the push rod 12 is connected to the sealing component 11, the other end of the push rod 12 is in sliding fit with the driving surface 524, when the driving key 51 is pressed, the driving key 51 moves, so as to drive the delivery pump 70 to work, meanwhile, the driving surface 524 of the first transmission structure 54 can push the push rod 12 to move, the push rod 12 drives the sealing component 11 to move, so that the first delivery hole 2145 is opened, and in the process, the first reset piece 14 is compressed to store elastic potential energy.

When the pressing action on the driving key 51 is removed, the driving key 51 moves toward the initial position, and in the process of moving the driving key 51 toward the initial position, the driving surface 524 of the first transmission structure 54 is separated from the push rod 12, and the push rod 12 resets under the action of the first resetting piece 14, so as to drive the sealing component 11 to move to close the first delivery hole 2145.

Therefore, the driving surface 524 can transmit the movement trend of the driving key 51 to the movement direction of the valve assembly 10 to the valve assembly 10, so as to realize the driving of the driving key 51 to the valve assembly 100, and the valve assembly has simple structure and easy assembly and disassembly.

In some embodiments, the drive surface 524 is disposed at an incline and the valve assembly 10 is disposed vertically. By matching the driving surface 524 with the valve assembly 10, the driving surface 524 is suitable for driving the valve assembly 10 to move downwards under the pressing of the driving key 51 so as to drive the sealing part 11 to open the first throwing hole 2145, so that the valve assembly is simple in structure and easy to realize.

In some embodiments, the second transmission structure 52 includes a worm and gear mechanism.

As shown in fig. 12 and 13, in other embodiments, the second transmission structure 52 includes a rack and pinion mechanism, where a rack 521 of the rack and pinion mechanism is engaged with the driving button 51, and a gear 522 of the rack and pinion mechanism is engaged with the dispensing pump 70, where the rack 521 extends along a moving direction of the driving button 51, for example, the rack 521 may extend in a horizontal direction or may extend in a diagonally downward direction.

Specifically, when the driving button 51 is pressed, the rack 521 moves synchronously, and the rack 521 is meshed with the gear 522, so that the rack 521 can drive the gear 522 to rotate, so that the delivery pump 70 can operate under the driving of the gear 522, and the delivery of the treating agent is realized. When the pressing action on the driving key 51 is canceled, the driving key 51 moves toward the initial position, so that the operation of the delivery pump 70 is stopped, and the structure is simple.

In some embodiments, the inner side of the driving key 51 is provided with a matching groove, and the dispensing device 100 further comprises a matching plate 525, wherein the matching plate 525 is in abutting matching with the bottom wall of the matching groove, and the matching is reliable. The first transmission structure 54 and the second transmission structure 52 are respectively disposed on a side of the matching plate 525 facing away from the driving key 51.

As shown in fig. 1, 6 and 11-12, according to some embodiments of the present invention, a second reset member 53 is disposed between the driving button 51 and the dispensing pump 70, for driving the driving button 51 to move toward the initial position, and the driving button 51 can be controlled to be automatically reset by the second reset member 53, so that the valve assembly 10 closes the first dispensing hole 2145, and the dispensing pump 70 is stopped, thereby stopping the dispensing of the treating agent and facilitating the subsequent control.

When the user presses the driving button 51, the rack 521 moves synchronously, the second reset member 53 is compressed, and because the rack 521 is meshed with the gear 522, the rack 521 can drive the gear 522 to rotate, so that the dispensing pump 70 can operate under the driving of the gear 522, and the dispensing pump 70 dispenses the treating agent, and meanwhile, the first transmission structure 54 can drive the valve assembly 10 to move, the first reset member 14 is compressed, and the valve assembly 10 opens the first dispensing hole 2145, so as to achieve dispensing of the treating agent.

When the pressing action on the driving key 51 is removed, the second transmission structure 52 moves towards the initial position under the action of the second reset element 53, so that the delivery pump 70 stops running, the driving surface 524 is separated from the push rod 12 in the process of moving the driving key 51 and the second transmission structure 52 towards the initial position, and the push rod 12 resets under the action of the first reset element 14, so that the sealing part 11 is driven to move to close the first delivery hole 2145.

Wherein the second reset member 53 is disposed between the mating plate 525 and the dispensing pump 70 to move the drive key 51 toward the initial position. That is, when the user removes the pressing action on the driving key 51, the second reset member 53 can return the driving key 51 to the initial position by driving the second transmission structure 52, so as to facilitate the subsequent control.

In some embodiments, the second transmission structure 52 has a first positioning portion 523, the dispensing pump 70 has a second positioning portion 703, and two ends of the second reset element 53 are respectively matched with the first positioning portion 523 and the second positioning portion 703, so that the second reset element 53 can be stably arranged between the second transmission structure 52 and the dispensing pump 70, and stable reset of the driving key 51 is achieved.
