[0039] The container mouth 100 is in communication with the inside of the container; the pump sleeve 200 is arranged in the container mouth 100 and extends into the inside of the container, the pump sleeve 200 has a cavity 210 for accommodating a pump component 400, and the pump sleeve 200 is provided with a liquid inlet 221 on an end opposite to the container mouth 100, the liquid inlet 221 being in communication with the cavity 210; the first check valve 300 is arranged between the liquid inlet 221 and the cavity 210 and can be unidirectionally conducted in the direction from the liquid inlet 221 to the container mouth 100.

[0040] It can be understood that the liquid in the container is separated from the pump component 400 by the pump sleeve 200, so that the pump head cannot be disassembled or replaced to a refill bottle when it is in a liquid contact state, and the first check valve 300 is used to prevent the liquid in the bottle from contacting the bacteria outside to cause cross infection, so that the use operation is more sanitary, fast and convenient.

[0041] In some embodiments, by the design of the embedded and fixed pump sleeve 200, only the pump sleeve 200 is used to realize liquid suction, so that when replacing and refilling, whether it is a manual pump or an automatic pump, the liquid can be replaced and refilled without soaking in the liquid, and the use operation is more sanitary, fast and convenient. In addition, the pump sleeve 200 and the first check valve 300 are arranged in cooperation with each other, thereby providing a replacement packaging structure without liquid contact and liquid dripping.

[0042] In some embodiments of the present application, the end of the pump sleeve 200 that is relatively far from the container mouth 100 is provided with a gradually narrowing flow guide portion 220 in the direction from the container mouth 100 to the liquid inlet 221. The liquid inlet 221 is provided at the relatively smallest end of the flow guide portion 220, the relatively largest end of the flow guide portion 220 is in communication with the cavity 210, and the first check valve 300 is arranged in the flow guide portion 220. It can be understood that the main function of the pump sleeve 200 is to isolate the pump component 400 from the liquid in the container, so that the pump component 400 is not soaked in the liquid and the liquid is not contaminated. Therefore, the liquid inlet 221 of the pump sleeve 200 is designed to allow the pump component 400 to smoothly contact the liquid in the container. In addition, the structure of the liquid inlet 221 is designed to further avoid the occurrence of liquid contamination and leakage, thereby further improving the user experience.

[0043] In some embodiments, the relatively large end of the flow guide portion 220 is used for interference sealing connection with the liquid inlet pipe 410 of the pump component 400, so that the liquid can flow smoothly. The relatively small end of the flow guide portion 220 is used to set a liquid pipe that extends into the liquid surface of the container, and the first check valve 300 is arranged between the two ends of the flow guide portion 220, so as to ensure that the first check valve 300 has better check effect.

[0044] In some embodiments of the present application, the pump sleeve 200 is arranged on the container mouth 100 by snap connection. It can be understood that the one-way pump sleeve 200 is matched with the packaging bottle by means of buckle + blocking point positioning. The outer side of the one-way pump sleeve 200 is interference sealed on the inner side of the bottle mouth by the sealing ring 230, and the inner side is sealed by the one-way valve, so as to ensure the sealing effect, so that the pump component 400 can still work normally after the pump sleeve 200 is arranged.

[0045] In some embodiments, the automatic liquid outlet device mainly pumps out the liquid in the bottle through the suction pipe and the one-way valve of the pump sleeve 200, and then enters the pump component 400 from the bottom of the liquid outlet device and is pumped out. The gas in the bottle mainly enters through the position where the pump component 400 is threadedly connected with the one-way pump sleeve 200, then passes through the step at the position where the one-way pump sleeve 200 is matched with the top surface of the bottle mouth (the position where the one-way pump sleeve 200 is matched with the top surface of the bottle mouth is designed with a circumferential small rib, which mainly ensures that the air passage is formed between the pump body and the pump sleeve 200), then enters the inside of the one-way pump sleeve 200 through the gap between the reinforcing ribs on the inside of the one-way pump sleeve 200, and then returns to the bottle through the air return on the inside of the one-way pump sleeve 200 to supplement the gas, so as to realize the pumping out of the liquid.

[0046] In some embodiments, the manual liquid outlet device pumps out the liquid in the bottle mainly through the suction pipe and the one-way valve of the pump sleeve 200, and then from the bottom of the liquid outlet device into the pump component 400 and is pumped out. The gas in the bottle is mainly returned through the gap between the main column and the locking cap component of the manual liquid outlet device into the body, and then through the gas return hole on the inner side of the body to the inside of the one-way pump sleeve 200, and then through the gas return hole on the inner side of the one-way pump sleeve 200 to return to the bottle to supplement the gas, so as to realize the pumping of the liquid.

[0047] In some embodiments of the present application, the inner side of the pump sleeve 200 is provided with a sealing ring 230, which is used to seal the connection between the pump sleeve 200 and the container port 100. It can be understood that the sealing ring 230 is arranged on the pump sleeve 200 and there is a predetermined distance between the sealing ring 230 and the connecting inner wall for snap connection. When the pump sleeve 200 is snap-fitted on the container port 100, the container port 100 will be embedded in the gap between the sealing ring 230 and the connecting inner wall. By designing the position of the sealing ring 230, the outer side of the one-way pump sleeve 200 is in interference sealing with the inner side of the bottle port through the sealing ring 230.

[0048] In some embodiments of the present application, the bottle port structure includes a pump component 400 which is detachably arranged on the pump sleeve 200 and partially extends into the cavity 210.
