Background

The daily chemical products belong to daily consumables, and the liquid daily chemical products are generally stored in a container and are discarded after being used up; for the convenience of use, the containers adopted by common liquid daily chemical products all comprise a liquid outlet pump structure, so that the single product selling price of the daily chemical products is higher, and the liquid containers are discarded integrally after the daily chemical products are used up. The consumer needs to buy a new packaging unit each time, which not only increases the burden of the consumer, but also causes a great deal of waste; the liquid outlet pump structure containing the liquid guide pipe on the market at present can not completely pump out the liquid, so that the liquid is remained in the container. The user can only remove the pump body to remove the liquid remaining in the container. In the case of a relatively viscous solution, it is difficult to pour the solution from the container. This affects the chemical properties of the liquid in the container if the water is poured out. In order to save trouble, part of consumers directly abandon the container containing the residual solution, directly buy new containers, and when the container plastics need to be recycled, the containers contain residual daily chemical products, and the containers need to be cleaned in a large amount, so that the environmental pollution is caused; at present, in most liquid container liquid outlet pump structures on the market, when the liquid outlet pump structures are used for the first time, the liquid outlet heads are popped up and pressed for use, but if the liquid outlet heads are locked again, the liquid outlet heads need to be pressed down and screwed, a certain amount of liquid can be pumped out in the process, and redundant waste is caused.

In summary, the existing liquid outlet pump mechanisms are mostly in an upper pressing type, and the liquid outlet pump mechanisms pump out the liquid in the form of liquid guide pipes, so that the liquid in the container cannot be completely pumped out, and the waste of the liquid is caused; and if the locking is required to be locked again, the operation is inconvenient and the waste of liquid can be caused.

Also chinese patent CN 208307412.U discloses an inverted horizontal pressing vacuum bottle, including the body that is used for holding liquid and inverts, the body top is equipped with the through-hole, body inside is equipped with piston one that can reciprocate along with how much of the inside content of body, the body lower part can be dismantled and be connected with the lantern ring, lantern ring inside is equipped with be used for with the pump core subassembly that the inside content of body was pumped, pump core subassembly is linked together and sliding seal with the nozzle that is fixed in the lantern ring bottom, the pump core subassembly passes through the button adaptor and links to each other with the button of level setting. However, the Chinese patent CN 208307412.U does not disclose a replaceable pump core component, and the nozzle is transversely sprayed, so that the use is not very convenient.
