Description

The foam type nozzle structure

Technical field

The utility model relates to a kind of liquid dispenser, particularly a kind of fluid jetting head structure that produces foam.

Background technology

As cleaning solutions such as hand lotions, common splendid attire mode is to be filled in the bottle, bottle is provided with a pressing structure, and pressing structure can be drawn the cleaning solution in the bottle and flow out from nozzle, can control the consumption of pushing the cleaning solution of being drawn each time by pressing structure.Though can control the consumption of cleaning solution by pressing structure, aqueous cleaning solution when nozzle flows out, run off from palm easily, make most users habitually to push repeatedly, cause the waste of cleaning solution.Moreover, when the user extrudes cleaning solution behind palm, the user also can habitually crumple both hands, make the cleaning solution on the palm form foam-like, the clean degree that reaches is thought by the side, if can't form foam, the user can think that the consumption of cleaning solution is not enough, and this pressing structure of pushing repeatedly flows out cleaning solution again, also is the waste that forms cleaning solution.

In order to solve the above problems, announce No. 409719 patent case and WO9208657 patent case has all proposed a kind of pressure head structure that can extrude foam-like solution as TaiWan, China, known foam type pressure head structure is in below plug-in mounting one suction pipe of a ladder pipe, and suit one pipe covers and spiral cover above the ladder pipe.Must be assembled on the bottle by spiral cover.The piston of packing in the ladder pipe again, wearing a bottom on it is closed and the base with through hole.Be serially connected with adapter in, upper connecting tube and nozzle in regular turn in the base top again.A steel ball is inserted and installing one spring in middle adapter in suction pipe top in the ladder pipe.The top of spring is inserted and is leaned against the base bottom.Ring is established a plurality of pores on the piston, again in piston below suit one circular valves.Upper connecting tube two ends installing filter screen.Position circular valves is not thereunder covered on pore, flowed into and have little air to flow in the ladder pipe and reduce solution.When flow of solution during through the filter screen at upper connecting tube two ends solution mix with air, form foam-like and extrude by nozzle.

Above-mentioned existing foam type pressure head structure forms the foam-like ejection with the solution in the bottle, so can reduce the consumption of solution effectively, also need not user's rubbing both hands repeatedly.Yet, known foam type pressure head structure, its structure is quite complicated, as coming ccontaining piston and spring by design ladder pipe, as a plurality of members such as piston, middle adapter, upper connecting tube and nozzles, and the combination that must consider piston, middle adapter, solution stream that upper connecting tube and nozzle constituted is closed, and increases the cost on manufacturing.Moreover, spring is a metal material, and be located among the solution stream, that is to say, spring can contact with solution, can make spring produce oxidative phenomena gradually for a long time, or makes the spring foul solution, or make spring lose original elasticity because of oxidation, and then shorten the service life of pressure head structure.

The utility model content

Existing foam type pressure head structure is quite complicated, and manufacturing cost is higher, and the spring of metal material directly contacts with solution, will cause the tired of the pollution of solution or spring itself, the optimal design of still non-foam formula pressure head structure.In view of this, the utility model proposes a kind of foam type nozzle structure that can effectively address the above problem.

According to the disclosed foam type nozzle structure of the utility model, include one and draw a body and a pressing member, wherein draw body and have an air chamber, one air inlet, and be communicated with one of air chamber and go into a liquid portion and a fluid portion, go into liquid portion and connect a drinking-water pipe, fluid portion connects a blast tube, and having one, pressing member is inserted into air chamber inner carrier spare, between pressing member and absorption body, be equiped with an elastic parts, make pressing member move and have one first movement travel and one second movement travel with respect to drawing body, pressing member is extracted solution and air to air chamber through drinking-water pipe and air inlet by first movement travel, after second movement travel of pressing member will make solution and air gas-liquid mixed form foamed, spray after making the continuous refinement of foamed solution via the screen member in the blast tube again.

According to the disclosed foam type nozzle structure of the utility model, move in air chamber by the control pressing member and to drive piston piece, the air that can draw the interior solution of container and the external world is to the air chamber gas-liquid mixed, and the blast tube place is provided with screen member again, can be with the foamed solution ejection of gas-liquid mixed, quite simple and easy on the structure, can reach the control liquid measure and form the solution foamed.Moreover elastic parts is arranged on the outside of drawing body, makes elastic parts can not contact with solution, can avoid the elastic parts foul solution of metal material and prolong elastic parts service life.

Below in conjunction with the drawings and specific embodiments the utility model is described in detail, but not as to qualification of the present utility model.
