Pressing head pump structure

Abstract

The invention relates to a pressure head pump structure, which mainly comprises a fixing tube, whose inside containing space is provided with a resetting component, a moveable tube positioned in the fixing tube, and the top of the moveable tube is provided with a communicated head, and the moveable tube can do the fro-and-to motion in an axial manner along the fixing tube to absorb the inside liquid by the pressing of the head and the resetting component, a blocking device connected to the bottom of the moveable tube in a close fitting fixing tube internal wall manner to make the blocking device and the moveable tube form an air blocking chamber with stopping function, and the air blocking chamber makes partial inside liquid stored in the air blocking chamber following the pressing of the moveable tube form an air blocking layer. The invention can prevent the grain of the inside liquid or the dull polish causing breathe freely by the abrasion to the tube wall, and can make the stored inside liquid in the bottle be completely absorbed following the pressing movable tube.

Description

technical field [0001] The invention relates to a pressure head pump structure. Background technique [0002] The container design of the liquid detergent used for general cleaning usually has a head pump that can be pressed elastically to draw the inner solution of the container, so that the need to open and close the lid and pour out the inner solution can be avoided during use. The user can conveniently draw out the internal solution by pressing the pressure head pump without any inconvenience. [0003] Please refer to the No. 90200119 patent application of "indenter safety lock ring structure" in Taiwan, China, which mainly utilizes an indenter with an inner and outer tube body, which is assembled at the open end of a container, and the indenter's The inner tube will move with the pressure of the pressure head. There is a piston and an elastic member at the bottom of the inner tube. When the inner tube is pressed down, the piston can draw out the inner solution of the c...

Problems solved by technology

[0004] However, although the existing structural design can achieve the effect of conveniently drawing the solution in the container, if the solution in the container is in the form of particles, such as industrial hand-washing cream, facial cleanser with scrub effect, etc. When the outer tube and the inner tube of the head are in use, the wall surface is easily worn by the particles of the inner solution, which may cause a gap and cannot be tightly sealed, so that the effect of compressing the piston to draw the inner solution is reduced, and even loses its due effect. On the whole, its practicability is poor, and there is still a need for improvement
