[0007] Furthermore, a limit plate is provided in the bottleneck of the bottle body, the limit plate is placed above the sealing rubber, and the bottom end of the spring abuts against the limit plate.

[0008] Furthermore, a limiting protrusion is provided on the outer wall of the pressing rod, and the limiting protrusion is placed between the limiting plate and the sealing rubber.

[0009] Furthermore, a sealing ring is sleeved on the outer wall of the limiting protrusion.

[0010] Furthermore, the bottle body is a split structure, including an upper bottle body and a lower bottle body, the upper bottle body and the lower bottle body are threadedly connected, the bottleneck is arranged on the upper bottle body, the drainage hole is arranged on the lower bottle body, and the drainage hole is connected to the one-way valve.

[0011] Furthermore, a nut is provided on the lower end surface of the pressing cover, and the top end of the pressing rod is threadedly connected to the nut.

[0012] The present invention has the following beneficial effects:

[0013] The present invention utilizes the air pressure principle to realize accurate control of the volume of detergent pressed each time, and can press multiple times until the liquid stored in the cavity is completely drained, while saving the self-priming pump and liquid level sensor in the automatic dispensing device, thereby greatly saving costs. Description of the drawings:

[0014] Figure 1 It is a cross-sectional view of the present invention.

[0015] Figure 2 This is a structural diagram of the present invention. Specific implementation method:

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] like Figure 1 and Figure 2 The device for pressing and dispensing liquid detergent for washing equipment of the present invention comprises a pressing cover 1, a spring 2, a sealing rubber 3, a pressing rod 4 and a bottle body 5, wherein the sealing rubber 3 is arranged in the bottleneck of the bottle body 5, the pressing rod 4 penetrates the sealing rubber 3, and the top end of the pressing rod 4 extends out of the bottle body 5. A nut is arranged on the lower end surface of the pressing cover 1, and the top end of the pressing rod 4 is threadedly connected with the nut. The bottom end of the pressing rod 4 is arranged in the bottle body 5, a horizontal pressing plate portion 41 is arranged at the bottom end of the pressing rod 4, and a drainage hole 53 is arranged on the bottom surface of the bottle body 5. The spring 2 is sleeved on the pressing rod 4, and the top end of the spring 2 abuts against the pressing cover 1, and the bottom end abuts against the bottleneck of the bottle body 5.

[0018] In order to limit the travel of the pressing rod 4, a limit plate 50 is provided in the bottleneck of the bottle body 5, the limit plate 50 is placed above the sealing rubber 3, and the bottom end of the spring 2 abuts against the limit plate 50. A limit protrusion is provided on the outer wall of the pressing rod 4, and the limit protrusion is placed between the limit plate 50 and the sealing rubber 3.

[0019] In order to further ensure the sealing effect, a sealing ring 6 is sleeved on the outer wall of the limiting protrusion.

[0020] The bottle body 5 in the present invention is a split structure, including an upper bottle body 51 and a lower bottle body 52, the upper bottle body 51 and the lower bottle body 52 are threadedly connected, the bottleneck is arranged on the upper bottle body 51, the drainage hole 53 is arranged on the lower bottle body 52, and the one-way valve 54 is connected to the drainage hole.

[0021] When in use, the detergent is introduced into the bottle body 5. Then the device is directly assembled on the matching structure of the washing machine by relying on the needle port (drain hole 53) at the bottom of the bottle body, and the pressing cover is pressed to use air pressure to press out the detergent. When pressed, the sealing ring 6 is sealed with the top of the sealing rubber 3, the sealing rubber 3 opens, and the air pressure enters the bottle body 5, and the liquid is pushed out through the drainage hole 53 and the one-way valve 54; when the pressing action is released, the pressing cover 1 returns to the position before pressing under the elastic force of the spring 2, driving the pressing rod and the sealing ring 6 to reset, at this time the limit plate 50 opens, and the horizontal pressure plate part 41 seals the lower end of the sealing rubber 3, and a negative pressure is formed in the cavity. The one-way valve of the drainage port is closed, and the discharged liquid cannot flow back. The air is filled into the cavity through the opening of the upper sealing ring, and the air pressure in the cavity is restored to the same as that outside the cavity.

[0022] The above description is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
