Description

Technical Field

[0001] The utility model relates to the technical field of press pumps, in particular to an automatic liquid-discharging press bottle. Background Art

[0002] A Chinese utility model patent with publication number CN219791062U discloses an automatic liquid discharge storage bottle, including a storage bottle, a sealing cover is arranged inside the storage bottle port, a bottom tube is arranged on the surface of the sealing cover, and the storage bottle port is connected to an inner cover body; an elastic supporting member is arranged on the top surface of the sealing cover, which is used to support a lifting tube to rise, an outer cover body is rotatably connected to the outer side of the inner cover body, and a pressure assembly is arranged on the top surface of the outer cover body, which is used to overcome the elastic force of the elastic supporting member and make the lifting tube descend.

[0003] The problem with the prior art is that the outer cover adopts a flip-top design. When the bottle falls, the spring will generate a rebound force under the pre-stressed state, so there is a risk of the outer cover being bounced open and liquid leakage. In addition, there are too many empty chambers and the remaining liquid cannot be fully used.

[0004] Therefore, the existing technology needs to be improved. Utility Model Content

[0005] In order to solve the above technical problems, the purpose of the utility model is to provide an automatic liquid discharging pressing bottle with a stable structure and complete liquid discharging.

[0007] The cover is screwed or buckled on the port of the bottle;

[0008] A receiving portion is provided at the opening of the bottle body, the upper part of the main column extends out from the opening of the bottle body, the pressing head is covered on the top of the main column, a spring is provided between the pressing head and the receiving portion, and after the cover body is closed on the bottle body port, the cover body can press the pressing head downward, and the pressing head can press the main column downward.

[0009] The cover is fastened by screw threads or buttons, so it is not easy to pop open even if the bottle falls. The structure is stable and safe.

[0010] As a further improvement of the above technical solution, the pump core comprises a body, a main column, a secondary column and a piston, a sliding cavity is provided in the body, a liquid inlet channel is provided at the bottom of the body, and the liquid inlet channel is communicated with the inside of the bottle body;

The locking cover is used to install, fix and seal the pump core to prevent leakage.

[0018] As a further improvement of the above technical solution, a sinking channel is provided at the center of the head, the sinking channel is plugged into the main column, and a silicone plug is sealed and installed on the sinking channel. The sinking channel is used to connect to the liquid outlet channel of the main column to allow the liquid to flow out, and the silicone plug is used to seal the liquid outlet channel when the user is not using the liquid to prevent leakage.

[0019] The beneficial effects of the utility model are:

[0020] 1. When the bottle cap is closed, the cover body presses the pressing head downward. At this time, the piston closes the liquid inlet channel. After the cover is opened, the pressing head bounces up under the action of the spring, and the piston is driven by the main column and the auxiliary column to absorb the liquid in the bottle into the sliding cavity, and then flows into the liquid outlet channel of the main column through the liquid guide hole for use, realizing the automatic liquid discharge function, which is convenient and fast.

[0021] 2. The cover is fixed to the bottle mouth by screw thread or button fastening. Even if the bottle falls, it is not easy to bounce off. A straw is arranged in the bottle to cooperate with the pump core to absorb the residual liquid. The structure is stable, safe, and the liquid is completely discharged.
