The further improvement is that: still include the mixing adjustment ware, the mixing adjustment ware includes barrel, turriform plunger and driving piece, the barrel seal peg graft with on the sunction inlet, the turriform plunger can follow axial through the driving piece and slide set up in the barrel in order to change the passageway sectional area of barrel liquid outlet department, the feed liquor pipe is installed to the lateral wall of barrel.

The further improvement is that: the driving piece includes threaded rod and threaded sleeve, the one end sealing connection that the liquid outlet was kept away from to the barrel has the end cover, the inboard of end cover has an axially extended well cavity section of thick bamboo, threaded sleeve along the axial slide set up in the well cavity section of thick bamboo, the turriform plunger link firmly in threaded sleeve's tip, the threaded rod with threaded sleeve connects, the free end of threaded rod extends to the end cover is outside.

The further improvement is that: and a knob is arranged at the extending end of the threaded rod.

The further improvement is that: nine gear marks are arranged on the end cover, and the gear marks correspond to the feeding distance of the tower-shaped plunger.

By adopting the technical scheme, the beneficial effects of the utility model are that:

the utility model discloses simple structure, high durability and convenient use, the sunction inlet can directly be connected with the foam liquid through the pipe, adopt the venturi principle, when rivers flow into the shrink tube at a high speed, the velocity of flow accelerates and produces the negative pressure, thereby inhale the foam liquid in the larynx and mix with rivers, independently install the foam mixer before removing the pipeline again, the realization is opened promptly and is used, in addition, slide through driving piece drive turriform plunger, thereby change the passageway sectional area of barrel liquid outlet department and adjust with the flow to the foam liquid, and then change the foam liquid mixing ratio, thereby adjust according to actual conditions, it is extravagant to avoid the foam liquid.

Fig. 2 is a partial enlarged view of a self-priming gun with adjustable mixing ratio according to an embodiment of the present invention.

Fig. 3 is a schematic diagram of a knob gear of a self-priming gun with adjustable mixing ratio according to an embodiment of the present invention.

In the figure: the device comprises a fluid channel 1, a Venturi tube assembly 2, a mixing regulator 3, a contraction tube 4, a throat tube 5, a diffusion tube 6, a cylinder 7, a tower-shaped plunger 8, a threaded sleeve 9, a liquid inlet tube 10, a threaded rod 11, an end cover 12 and a knob 13.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

The first embodiment is as follows:

referring to fig. 1-2, the embodiment of the present invention discloses a self-priming gun with adjustable mixing ratio, including the self-priming gun body, the self-priming gun body has a fluid passage 1, a venturi tube assembly 2 is installed on the fluid passage 1, the venturi tube assembly 2 includes a contraction tube 4, a throat tube 5 and a diffusion tube 6, the contraction tube 4, the throat tube 5 and the diffusion tube 6 are connected in sequence along the liquid outlet direction, the throat tube 5 has been provided with a suction inlet.

The suction inlet can be directly connected with the foam liquid through a conduit, and by adopting the Venturi principle, when water flow flows into the contraction pipe 4 at a high speed, the flow speed is accelerated and negative pressure is generated, so that the foam liquid is sucked into the throat pipe 5 and mixed with the water flow, a foam mixer is not independently installed before a pipeline, and the instant use is realized.
