Abstract
The utility model relates to the technical field of daily necessities, be a rotatory current-limiting press cover particularly, include the base fixed with liquid container, be equipped with a through-hole on the base, still be equipped with on the base can the base free rotation's press cover, be equipped with the extrusion orifice on the press cover, the press cover bottom be equipped with the corresponding opening of through-hole. The utility model provides a rotatory current-limiting press cover, through the cooperation between opening and the through-hole, make the press cover can be opened and close at any time according to the demand, and the liquid in the container has just so been avoided receiving the direct problem that flows out from the lid after the extrusion. Simultaneously the utility model has the advantages of simple structure, convenient to use personnel operate.
Description
Technical Field
The utility model relates to the technical field of daily necessities, a rotatory current-limiting press cover particularly.
Background
In our daily life, a press cap is often used on daily necessities such as hand sanitizer, shampoo and the like to press and squeeze out the liquid inside, but in the process of actual use, the daily necessities with the press cap are very inconvenient to carry, and easily collide with the press cap or a container, so that the liquid inside is squeezed out.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to solve prior art's not enough, provide a novel press cap with current-limiting function to avoid the inside liquid of container to be extruded at will, cause inconvenience to the user.
In order to achieve the purpose, the technical scheme adopted by the rotary current-limiting press cover is as follows:
the rotary current-limiting press cover comprises a base (1) fixed with a liquid container, wherein a through hole (2) is formed in the base, a press cover (3) capable of freely rotating with the base is further arranged on the base (1), an extrusion opening is formed in the press cover (3), and an opening (4) corresponding to the through hole (2) is formed in the bottom of the press cover (3).
The utility model discloses still have following preferred technical scheme:
furthermore, a limiting ring is further arranged on the pressing cover (3) and used for enabling the top of the pressing cover (3) to be exposed above the base (1).
Furthermore, an observation port is arranged on the limiting ring and used for observing the coincidence degree of the opening (4) and the through hole (2).
Further, the pressing cover (3) can move up and down along the base.
Further, when the opening (4) is partially or completely coincident with the through hole (2), the liquid in the liquid container can be squeezed out of the squeezing port, and when the through hole (2) is completely closed, the liquid in the liquid container cannot be squeezed out of the squeezing port.
Beneficial effects of the utility model
The utility model provides a rotatory current-limiting press cover's advantage lies in: the utility model discloses a cooperation between opening and the through-hole, make press the lid can be opened and close at any time according to the demand, has just so avoided the liquid in the container to receive the direct problem that flows from the lid after the extrusion. Simultaneously the utility model has the advantages of simple structure, convenient to use personnel operate.

Detailed Description
The technical solution adopted in the present application is further described below with reference to the following embodiments and the accompanying drawings.
Common press cover on the market has two kinds, one kind in the use, need press the container and extrude inside liquid, this kind of press cover simple structure, but prevent leaking the effect relatively poor, still one kind mainly comprises catheter, feed liquor valve, spring, air discharge valve, piston, drain pipe, stock solution section of thick bamboo etc.. The working principle of the water pump is the same as that of a piston type water pump. The air in the liquid storage cylinder is discharged by utilizing the movement of the piston, so that the difference between the internal air pressure and the external air pressure is caused, and the liquid rises under the action of the air pressure and is discharged out of the liquid discharge pipe from the liquid discharge pipe. When the liquid outlet pipe is pressed downwards by hand, the spring is compressed to make the liquid inlet valve be closed downwards, at the same time, the piston can be moved downwards, and at the same time the air-exhausting valve (opened, the liquid in the liquid storage cylinder can be flowed out of the liquid outlet pipe from the liquid outlet pipe, and when the hand is released, the spring can be restored to original natural state, and can make the piston be moved upwards, and the air-exhausting valve be closed, and the liquid inlet valve is opened, and under the action of external atmospheric pressure the liquid can be fed into the liquid storage cylinder from liquid guide pipe through the liquid inlet valve.
To two kinds of common press lids above, the utility model discloses an above-mentioned problem has been solved to two different embodiments.
Example 1
Referring to fig. 1, for the first technical solution of the present invention, in embodiment 1, the base 1 is fixed on a liquid container, the base 1 is provided with a through hole 2, the liquid can be extruded from the through hole 2, the base 1 is further provided with a pressing cap 3, the pressing cap 3 is a hollow structure, the bottom of the pressing cap is provided with an opening 4, the opening 4 can be matched with the through hole 2, when the opening 4 and the through hole 2 completely coincide or partially coincide, the liquid in the liquid container can flow out from the opening, and since the pressing cap is rotatable, the pressing cap only needs to be rotated to a position completely sealing the through hole, so as to prevent the liquid in the liquid container from leaking.
Example 2
The above, only for the concrete implementation of this utility model, but the scope of protection of this utility model is not limited to this, and any person skilled in this technical field is in the technical scope of this utility model discloses, according to the technical scheme of this utility model and novel design add in equal replacement or change, all should be covered in the scope of protection of this utility model.
Claims (5)
1. The rotary current-limiting press cover is characterized by comprising a base (1) fixed with a liquid container, wherein a through hole (2) is formed in the base, a press cover (3) capable of freely rotating on the base is further arranged on the base (1), an extrusion opening is formed in the press cover (3), and an opening (4) corresponding to the through hole (2) is formed in the bottom of the press cover (3).
2. A rotary current-limiting press cap according to claim 1, wherein the press cap (3) is further provided with a limiting ring for exposing the top of the press cap (3) above the base (1).
