Abstract
The utility model discloses a liquid spraying pump, comprising a pump body, a plunger, a button, a spring and an end cap. One end of the pump body is an imbibition opening and the other end is sealed by the end cap. The inboard of the imbibition opening is provided with an unidirection check valve. The plunger is arranged in the pump body. The connecting rod of the plunger penetrates the end cap and is connected with the button. The spring is arranged in the pump body and one end of the spring is connected with the plunger. The liquid spraying pump is characterized in that the pump body is provided with a liquid spraying opening connected with a liquid spraying pipe; the outlet end of the liquid spraying pipe is provided with an unidirection check valve. The utility model has the advantages of simple structure and good sealability. The liquid spraying pump can spray liquid to any direction. The liquid spraying pump with the structure is easily arranged on other structures.
Description
One, technical field
The utility model relates to a kind of pump, particularly a kind of hand push type Liquid spraying pump.
Two, background technique
The kind of pump is a lot, it meets the tendency very extensive, the hand push type Liquid spraying pump is exactly wherein a kind of, it is mainly used in the daily living article, as daily cosmetics etc., its working principle is to press the button ejection liquid, and release button sucks liquid, therefore structurally need be provided with two one-way valves, its spout operated by rotary motion is at an end of button.There are two shortcomings in existing hand push type Liquid spraying pump: the one, and complex structure, volume are bigger; The 2nd, sealing is poor, can not use in any direction.
Three, summary of the invention
The purpose of this utility model provides the Liquid spraying pump that a kind of simple in structure, good airproof performance, liquid sucting port and mouth spray are positioned at same end.
For achieving the above object, Liquid spraying pump described in the utility model comprises the pump housing, piston, button, spring and end cap, and an end of the pump housing is a liquid sucting port, and the other end is by end bracket enclosed, be provided with unidirectional check valve in the inboard of liquid sucting port, piston places in the pump housing, and its connecting rod links to each other with button after passing end cap, and spring places in the pump housing, one end and piston join, it is characterized in that being provided with on the pump housing mouth spray, this mouth spray links to each other with liquid-spraying pipe, is provided with unidirectional check valve at the outlet end of liquid-spraying pipe.
The unidirectional check valve that is arranged on the outlet end of liquid-spraying pipe is a spring-backed quill, and this spring-backed quill is enclosed within the outlet end of liquid-spraying pipe, is provided with spray orifice on its top.
The unidirectional check valve that is arranged on the liquid sucting port inboard is a spheroid.
Working principle of the present utility model is: pick-up tube is reached in the sucked liquid, the nozzle subtend of liquid-spraying pipe is sprayed the position.Press the button, the liquid in the pump housing is under the piston compressing, and pressure raises, and the unidirectional check valve in the suction port is blocked liquid and entered, and the liquid in the pump housing sprays from ejiction opening.Release button, piston are under the effect of spring, and the fluid pressure in the return, the pump housing lowers, and under negative pressure, the unidirectional check valve in the suction port leaves suction port, thereby liquid is inhaled in the pump housing, and the unidirectional check valve at mouth spray place is only logical.So move in circles, liquid constantly is sprayed onto on the object.
When the unidirectional check valve of the outlet end that is arranged on liquid-spraying pipe is selected spring-backed quill for use, as long as be provided with the big through hole of pin hole, when pressing the button on the top of spring-backed quill, through hole is strutted, and the liquid in the pump housing will spray from through hole, when release button, under negative pressure, through hole shrinks and seals.Therefore this spring-backed quill is unidirectional check valve.
The utility model compared with prior art, its remarkable advantage is: 1, saved another non-return one-way valve on the pump housing, thereby simple in structure; 2, the end at the pump housing seals with end cap, thereby good airproof performance; 3, use this Liquid spraying pump, can carry out the injection of any direction; 4, the Liquid spraying pump of this structure is installed on other structures at an easy rate, thereby applied widely.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model.
Five, embodiment
The Liquid spraying pump that the utility model relates to comprises the unidirectional check valve 8 of unidirectional check valve 6, liquid-spraying pipe 7 and the liquid-spraying pipe of the pump housing 1, piston 2, button 3, spring 4, end cap 5, liquid sucting port.The pump housing 1 is the stepped shape cylindrical structure, and one section diameter is big, one section diameter is little, and a ball recess is arranged at the one section bottom little at diameter, is provided with suction port in the bottom of groove, and this suction port links to each other with pick-up tube, and the unidirectional check valve 6 of spheroidal places in the ball recess.The both sides of end cap 5 are equipped with circular groove, and the opening end eye-splice of the pump housing 1 is provided with gasket seal in the bottom of this circular groove in a side circular groove of end cap 5.The piston head of "T"-shaped piston 2 places in the pump housing, and its connecting rod is enclosed within on the tubular button 3 after passing gasket seal and end cap 5, and button 3 also has an outer cylinder, and button 3 is when moving up and down, and this outer cylindrical wall is slided along the circular groove of the opposite side of end cap 5.Spring 4 places in the pump housing, and one end and piston join, and the other end is supported on the bottom of the pump housing.On little one section of the diameter of the pump housing 1, be reserved with mouth spray, this mouth spray and liquid-spraying pipe join, and the sleeve pipe of being made by rubber material at the oral area cover one of liquid-spraying pipe 8 is as unidirectional check valve.
