Cosmetic bottle hydraulic pump

Abstract

The invention relates to a cosmetic bottle hydraulic pump which comprises a shell. A liquid storage barrel is arranged in the shell. A sealing cover is arranged at the upper end of the liquid storagebarrel. Multiple liquid outlet holes are formed in the peripheral face of the liquid storage barrel. A liquid extraction pipe is arranged at the lower end of the shell. One end of the liquid extraction pipe penetrates through the lower end of the shell and communicates with the lower end of the liquid storage barrel, a liquid extraction filter element is arranged at the other end of the liquid extraction pipe, and the peripheral face of the liquid extraction pipe is sleeved with a protection cover. A liquid extraction bag is arranged at the position of the side of the lower end of the shell, an air introduction pump is arranged at the outer end of the liquid extraction bag, and a one-way valve is arranged between the inner end of the air introduction pump and the side position of the liquid storage barrel. A spray head is arranged at the end of the shell and connected with the liquid storage barrel. By means of the cosmetic bottle hydraulic pump, the efficiency of carrying out stirringtreatment on cosmetic liquid is greatly improved; and the cosmetic liquid can be conveniently pressed and pumped, and the cosmetic liquid can be sprayed out through the spray head.

Description

technical field [0001] The invention relates to a hydraulic pump, in particular to a cosmetic bottle hydraulic pump. Background technique [0002] The hydraulic pump is the power component of the hydraulic system. It is driven by an engine or an electric motor. It sucks oil from the hydraulic oil tank, forms pressure oil and discharges it, and sends it to the actuator. Hydraulic pumps are divided into gear pumps, plunger pumps, vane pumps and screw pumps according to their structure. Types of commonly used hydraulic pumps: 1. According to whether the flow rate can be adjusted, it can be divided into: variable pump and quantitative pump. The output flow can be adjusted according to the needs is called the variable pump, the flow can not be adjusted called the quantitative pump. 2. According to the pump structure commonly used in the hydraulic system, it is divided into three types: gear pump, vane pump and plunger pump. The drive shaft of the hydraulic pump cannot bear rad...

AI Technical Summary

Problems solved by technology

If due to manufacturing reasons, the coaxiality of the pump and the coupling exceeds the standard, and there is a deviation during assembly, the centrifugal force will increase the deformation of the coupling as the pump speed increases, and the large deformation will increase the centrifugal force.

Causes a vicious cycle, resulting in vibration and noise, which affects the service life of the pump

In addition, there are other influencing factors such as the coupling pin is loose and not fastened in time, and the rubber ring is worn and not replaced in time.

The existing hydraulic pump is inconvenient to be installed on the end of the cosmetic bottle, and the efficiency of pumping the liquid in the cosmetic bottle is low. The existing cosmetic bottle does not have the function of pressing and transporting the cosmetic liquid. low efficiency
