The direction of the central axis of the sleeve 1131 extends obliquely. During the process of closing the first delivery hole 2145 of the valve assembly 10, that is, the valve assembly 10 moves upward from the position shown in FIG. 9 to the position shown in FIG. The hole of the first delivery hole 2145 is interference fit along the radial direction 2147 to realize sealing. Since the first sealing part 1132 has a certain slope, the first sealing part 1132 can also play a guiding role.

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

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

In the process of closing the first injection hole 2145 of the valve assembly 10, the first sealing part 1132 is inserted into the first injection hole 2145, and can interfere with the hole of the first injection hole 2145 along 2147 in the radial direction, thereby achieving sealing. The first sealing part 1132 has a certain slope, so the first sealing part 1132 can also play a guiding role.

Further, when the valve assembly 10 is moved into place, the second sealing portion 1133 is in close contact with one side surface of the first delivery hole 2145, specifically, the first sealing lip 11331 is in close contact with the side surface of the first delivery hole 2145 (for example , the plane where the lower end opening of the first injection hole 2145 is located) cooperates, thereby realizing end face sealing.

Therefore, the sealing member 113 in the present application has a double sealing function, and the reliability of the sealing can be improved when the valve assembly 10 closes the first delivery hole 2145 .

Specifically, one end of the push rod 12 is connected to the sealing member 11, and the other end of the push rod 12 is slidably matched with the driving surface 524. When the driving button 51 is pressed, the driving button 51 moves, thereby driving the dosing pump 70 to work. At the same time, the first The driving surface 524 of a transmission structure 54 can push the push rod 12 to move, and the push rod 12 drives the sealing member 11 to move, thereby opening the first injection hole 2145. During this process, the first reset member 14 is compressed to store elastic potential energy.

When the pressing effect on the drive button 51 is cancelled, the drive button 51 moves toward the initial position. During the process of the drive button 51 moving to 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 is The action of the first reset member 14 resets, thereby driving the sealing member 11 to move to close the first injection hole 2145 .

Therefore, the driving surface 524 can transmit the movement trend of the driving button 51 to the valve assembly 10 in the moving direction of the valve assembly 10 to realize the driving of the valve assembly 100 by the driving button 51 , with a simple structure and easy assembly and disassembly.

In some embodiments, the driving surface 524 is inclined and the valve assembly 10 is vertical. By cooperating the driving surface 524 with the valve assembly 10, the driving surface 524 is suitable for driving the valve assembly 10 to move downward under the pressing of the driving button 51 to drive the sealing member 11 to open the first injection hole 2145, which is simple in structure and easy to implement.

Specifically, when the drive button 51 is pressed, the rack 521 moves synchronously. Since the rack 521 meshes with the gear 522, the rack 521 can drive the gear 522 to rotate, so that the dispensing pump 70 can run under the drive of the gear 522. Realize the injection of treatment agent. When the pressing effect on the driving button 51 is cancelled, the driving button 51 moves toward the initial position, so that the dispensing pump 70 stops running, and the structure is simple.

In some embodiments, a matching groove is provided on the inner side of the driving button 51 , and the delivery device 100 further includes a matching plate 525 , and the matching plate 525 is in contact with the bottom wall of the matching groove, and the cooperation is reliable. Wherein, the first transmission structure 54 and the second transmission structure 52 are respectively arranged on the side of the matching plate 525 facing away from the driving button 51 .

As shown in Figures 1, 6, and 11-12, according to some embodiments of the present application, a second reset member 53 is provided between the driving button 51 and the delivery pump 70, for driving the driving button 51 to move toward the initial position The second reset member 53 can be used to control the automatic reset of the driving button 51, so that the valve assembly 10 closes the first injection hole 2145, and stops the operation of the injection pump 70, thereby stopping the injection of the treatment agent and facilitating subsequent control.

When the user presses the driving button 51, the rack 521 moves synchronously, and the second reset member 53 is compressed. Since the rack 521 meshes with the gear 522, the rack 521 can drive the gear 522 to rotate, so that the feeding pump 70 can be driven by the gear 522. Down to run, so that the injection pump 70 injects treatment agent, and at the same time, the first transmission structure 54 can drive the valve assembly 10 to move, the first reset member 14 is compressed, the valve assembly 10 opens the first injection hole 2145, and realizes the injection of the treatment agent.
