Abstract
The invention discloses a dual-channel backflow-preventing foam pump structure which comprises a body, a meshed column and a pressing head, wherein the meshed column and the pressing head are arranged on the upper portion of the body. An air piston and a liquid piston are arranged in the body, wherein the air piston is located on the upper portion, and a valve is arranged between the air valve and the liquid valve. A movable rod is sleeved with the liquid piston, and the lower end of the movable rod is mounted in a rod sleeve. When the pressing head is pressed down, the valve is opened, the movable rod drives the liquid piston to be opened at the same time, and liquid and air flow to the direction of the meshed column; when the pressing head rebounds, the valve is closed, liquid backflow is prevented, and the movable rod is matched with the rod sleeve to close the liquid piston to prevent liquid backflow.
Description
Technical field
The present invention relates to the pump housing, be specially a kind of two pass counterflow-preventing foam pump structure.
Background technology
Now, people more and more start the health problem paying close attention to self, in order to keep the clean of human body, present people get used to when washing one's hands, washing one's face or taking a shower being undertaken by some clean liquids, in order to the cleaning solutions such as a large amount of face sanitizers, hand cleanser, shower cream have appearred in needs now on the market that meet people, and it is easy to use in order to place, foam pump is just arisen at the historic moment, and it makes the people when concrete use this kind of liquid quantitative can be extruded to reach the object of cleaning use.
But, there is the problem making bubble ability in existing foam pump, simultaneously, most product after liquid uses half because liquid countercurrent causes still phenomenon to occur, What is more, adverse current cause liquid dry and crystallization on net post, and then pump head normally can not be used, thus affects the intuitional and experiential thinking of customer.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the invention provides a kind of two pass counterflow-preventing foam pump structure.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of two pass counterflow-preventing foam pump structure, comprise body and be arranged at the net post above it, head, air piston and liquid piston are installed in described body, wherein, described air piston is positioned at top, valve is provided with before itself and liquid piston, portable bar is arranged with in described liquid piston, described portable bar lower end is installed in bar cover, when head presses down, valve open, portable bar drives liquid piston to open simultaneously, liquid-to-air flows toward net post direction, when head resilience, valve closing, prevent liquid countercurrent, portable bar depending post cover is closed simultaneously, prevent liquid backflow.
As the improvement of technique scheme, described valve is connected with air piston and liquid piston by glue thin slice to be opened/closed.
As the improvement of technique scheme, described portable bar lower end is set to plush copper, and described bar set upper side is provided with the boss being mated installation, and when portable bar moves up and down to top in bar cover, described plush copper is placed on boss and portable bar is closed.
As the improvement of technique scheme, described portable bar connects head in upper end, is provided with glass ball valve and sebific duct below it.
As the improvement of technique scheme, described body upper end fastens and is provided with blind nut, is provided with folder against pressure above described blind nut.
As the improvement of technique scheme, described bar cover is fixed on body lower end, is provided with spring between itself and described liquid piston.
The beneficial effect that the present invention brings has:
Major design of the present invention has the two controlled counter-current configuration in place, one, liquid piston coordinates with valve glue thin slice, when head is pressed, valve glue thin slice is opened, air is gone out toward net post place, when head resilience, valve glue thin slice is closed, just liquid countercurrent can be prevented, its two, liquid piston coordinates with portable bar, when head is pressed portable bar coordinate liquid piston open, liquid flows to net post by open position, when head resilience, portable bar is closed, and just can prevent liquid backflow, and then solve the problems of the technologies described above.
Accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the invention will be further described,
Accompanying drawing 1 is structure cutaway view of the present invention.
Detailed description of the invention
With reference to accompanying drawing 1, the present invention is for we providing a kind of two pass counterflow-preventing foam pump structure, it mainly comprises body 11 and is arranged at net post 2, the head 1 above it, air piston 5 and liquid piston 8 are installed in body 11, wherein, air piston 5 is positioned at top, is provided with valve 7 before itself and liquid piston 8, be arranged with portable bar 6 in liquid piston 8, the lower end of portable bar 6 is installed in bar cover 10.
When head 1 presses down, valve 7 is opened, portable bar 6 drives liquid piston 8 to open simultaneously, liquid-to-air is toward the flowing of net post 2 direction, and when head 1 resilience, valve 7 is closed, prevent liquid countercurrent, portable bar 6 depending post cover 10 is closed simultaneously, prevents liquid backflow, is formed two pass backflow preventing structure of the present invention with this.
In concrete structure, valve 7 is connected with air piston 5 and liquid piston 8 by glue thin slice to be opened/closed.And portable bar 6 lower end is set to plush copper 14, the upper end of bar cover 10 is provided with the boss 15 being mated installation, and when portable bar 6 moves up and down to top in bar cover 10, plush copper 14 just can be placed on boss 15 and portable bar 6 is closed.
Other aspects; portable bar 6 connects head 1 in upper end; glass ball valve 12 and sebific duct 13 is provided with below it; simultaneously; body 11 upper end fastens and is provided with blind nut 4; be provided with folder 3 against pressure above blind nut 4 to protect product formation, above-mentioned bar cover 10 is fixed on the lower end of body 11, is provided with spring 9 between itself and liquid piston 8.
In a word, major design of the present invention has the two controlled counter-current configuration in place:
One, liquid piston 8 coordinates with valve 7 glue thin slice, and when head 1 is pressed, valve 7 glue thin slice is opened, air is gone out toward net post 2 place, when head 1 resilience, valve 7 glue thin slice is closed, and just can prevent liquid countercurrent, they are two years old, liquid piston 8 coordinates with portable bar 6, when head 1 is pressed, portable bar 6 coordinates liquid piston 8 to open, and liquid flows to net post 2 by open position, and when head 1 resilience, portable bar 6 is closed, just can prevent liquid backflow, and then solve the problems of the technologies described above.
Finally it should be noted that, the above is preferred embodiment of the present invention, and the present invention is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present invention with identical means, all should belong to protection scope of the present invention.
