Background

Patent document CN201505593U discloses a solution distributor with a rotary switch at 6/16/2010, in which a one-way valve is fixedly arranged at the bottom of a body, and the structure is high, which further results in a large vacuum bottle height to which the solution distributor is applied, and a short vacuum bottle cannot adopt the solution distributor, so that the vacuum bottle type adopting the solution distributor is not diversified enough.

The common structure of cosmetic solution distributor valve that has now on the current market all is fixed, unable activity, and the pressure that the valve can bear is generally less, and the inner passage of valve is usually thinner, often can't carry out effective short-term test to its function to judge whether the product has gas leakage, off-position, adorn bad phenomenon such as part less in producing the kind.

Disclosure of Invention

The invention provides a sealing and reinforcing pump core with a movable valve for a solution distributor, which can enlarge the range of the solution which can be filled, reduce the height of a vacuum bottle and enhance the sealing performance before use.

The technical scheme adopted by the invention for solving the technical problems in the prior art is as follows: a sealed and reinforced pump core with a movable valve for a solution distributor comprises a body, wherein a piston is arranged in the body and connected to a piston rod, a valve port is formed in the bottom of the body, a push rod is arranged in the valve port and is plugged in the valve port, a central overflowing channel is arranged in the push rod, a valve seat is arranged at the upper part of the central overflowing channel, and a valve body is arranged on the valve seat; the lower end of the piston rod is provided with a push head, and before the valve body is used, the valve body is pressed on the valve seat by the push head.

the piston rod is an auxiliary column, the upper end of the auxiliary column is fixedly connected with the main column, the main column is arranged in the collar piece in a penetrating mode and is in sliding connection with the collar piece, the collar piece is fixedly arranged on an upper inner opening of the body, a large spring is clamped between the upper end face of the collar piece and the lower edge of the upper end of the main column, a small spring is clamped between the main column and the piston, and the piston is in sliding connection with the auxiliary column.

Before use, the lower part of the push rod extends out of the body.

The valve body is of a spherical structure, and a valve body limiting structure is arranged at the top of the inner side of the push rod.

The valve body adopts an umbrella-shaped structure.

The valve body is equipped with the hemisphere main part and encircles the annular support around the hemisphere main part, the hemisphere main part through the connection slat that diverges with the annular support is connected.

The invention has the advantages and positive effects that: the push rod is used as the valve seat, so that the inner diameter of the valve seat can be increased, the pressure born by the one-way valve can be increased, the viscosity of the solution which can be filled can be further increased, the range of the solution which can be filled can be enlarged, the height of the vacuum bottle is reduced, and the type of the vacuum bottle is diversified; the push rod is used as the valve seat, so that the valve is convenient to assemble, the defects of air leakage, dislocation, few parts and the like can be conveniently and quickly detected, and meanwhile, the valve body can be effectively prevented from being misplaced; by adopting the push rod as the valve seat, a consumer can judge whether the materials in the packaging container are used or not by observing the position of the push rod. Before the use, the valve body is pressed and closed on the valve seat by the push head, so that the inverted leakage of a container and the pumping of a solution can be effectively avoided before the use, and the sealing performance can be enhanced. By adding a small spring between the main column and the piston, the suction force of the pump core can be increased from-20 MPa to-30 MPa. Before the pump core is used, the lower part of the push rod extends out of the body, so that the suction pipe can be connected to the lower end of the push rod, and the application range of the pump core is expanded.

In this embodiment, the piston rod is an auxiliary column 6, the upper end of the auxiliary column 6 is fixedly connected with a main column 1, the main column 1 is inserted into a collar 3 and is slidably connected with the collar 3, the collar 3 is fixedly arranged in an upper inner opening of the body 4, a large spring 2 is clamped between the upper end surface of the collar 3 and the upper end lower edge of the main column 1, a small spring 11 is clamped between the main column 1 and the piston 5, and the piston 5 is slidably connected with the auxiliary column 6. The suction force of the pump core can be increased by adding the small spring 11.

In this embodiment, before use, the lower part of the push rod 7 extends out of the body 4, so that a suction pipe can be connected to the lower end of the push rod, and the application range of the pump core is expanded.

referring to fig. 1-1 and 2-1, the valve body 8 is of a spherical structure, and a valve body limiting structure 10 is arranged at the top of the inner side of the push rod 7.
