When coefficient of foaming did not meet actual user demand, its required foam solution was bigger than the amount of finishing the required foam solution of coefficient of foaming and water, Air mixing liquid with the amount of the mixed liquor of water, thereby caused the waste of foam solution and water, had increased use cost.
The utility model content
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of mixing quality that improves foam and water is provided, improves the foam mixer of coefficient of foaming.
The purpose of this utility model is achieved through the following technical solutions:
A kind of foam mixer is provided, comprise foaming connector and foams mix tube successively, described foams mix tube comprises into bubble end and blebbing end, the bubble end that advances of described foams mix tube is connected with described foaming connector, described foams mix tube offers air admission hole near described position of advancing to steep end, be provided with foam generation net in the described foams mix tube, described foaming connector offers the throttle orifice that is communicated to described foams mix tube.
Wherein, described foams mix tube is the cylinder setting.
Wherein, to offer into two be conical, the middle circular hole that is to described throttle orifice.
Wherein, described air admission hole is set to any shape in rectangular opening, circular port, the tri-angle-holed and slotted eye.
Wherein, described foam generation net is arranged at the part of close described blebbing end in the described foams mix tube.
Wherein, described foam generation net is along the center line of described foams mix tube and is symmetrical arranged.
Wherein, the end that described foam takes place to net comes together in the center line of described foams mix tube, and its other end is arranged at internal face or the blebbing end of described foams mix tube.
Wherein, described foam generation net multilayer arranges.
Wherein, described foaming connector is connected by fastening glue with described foams mix tube.
Wherein, the blebbing end of described foams mix tube is circumscribed with the sprinkling dish.
The beneficial effects of the utility model: the mixed liquor of foam solution and water with certain flow velocity from the throttle orifice of foaming connector when flowing to the foams mix tube, " jet " phenomenon can appear, the mixed liquor of foam solution and water can will arrange near the air that advances the bubble end in the foams mix tube after flowing through throttle orifice simultaneously, thereby advance near the formation negative pressure bubble end what the foams mix tube was connected with the foaming connector, it is Venturi tube effect, air outside then enters the foams mix tube and carries out secondary with mixed liquor and mix from air admission hole, be mixed with foam solution, the mixed liquor of the water and air foam generation net of flowing through hastily, foaming takes place at foam under the effect of net and arrive certain coefficient of foaming, improve the mixing quality of foam and water, improve coefficient of foaming, the mesh that takes place to net by foam sprays from the blebbing end then, simultaneously, finish the required foam solution of coefficient of foaming and water, the amount of Air mixing liquid is littler than the amount of the mixed liquor of finishing required foam solution and water in prior art, and the utility model has been saved cost.
Description of drawings
The utility model is described in further detail to utilize accompanying drawing, but the embodiment in the accompanying drawing does not constitute any restriction of the present utility model, for those of ordinary skill in the art, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to the following drawings.
