The existing blockage controller has an excessively complex structure, and the design purpose can be simplified.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the above-mentioned problem of current, provide a high-pressure squirt valve structure.

The purpose of the utility model can be realized by the following technical proposal: a high-pressure water gun valve structure is arranged in a middle handle in the middle of a water gun and comprises an inner sleeve and a one-way valve, wherein the side edge of the inner sleeve is connected with a side pipe which is communicated with a cavity of the inner sleeve and is connected with a pump body in the head of the water gun,

it is characterized in that the preparation method is characterized in that,

the upper end of the inner sleeve is blocked, only the lower opening and the side opening of the connecting side pipe are arranged,

the lower opening is provided with an annular step and is in threaded connection with an external connecting piece, the check valve is arranged in the lower opening,

the one-way valve is an integrated rubber cap, a circle of brim is arranged below the rubber cap, the brim is clamped between the external connecting piece and the annular step of the lower opening of the inner sleeve, the cap body of the rubber cap is arranged in the inner sleeve,

the top of the cap body is provided with a slit, the outside of the top is an inclined plane, and the inclined plane extends downwards from the slit.

The top of the cap body is provided with two inclined surfaces which clamp the slit in the middle, and a triangular chamfer is formed on the top of the cap body and the section perpendicular to the slit.

The inner sleeve is externally provided with a clamping part, the middle handle is internally provided with a clamping groove and consists of an openable shell, and the clamping part of the inner sleeve is limited in the clamping groove.

Compared with the prior art, the utility model discloses a water piping connection just is in the handle below on external connection spare, consequently holds comparatively balanced laborsaving. The rubber cap is arranged, so that the cost is saved, and the economic benefit is good.

The water pipe is mainly connected with the water barrel and a tap water faucet,

the water tap supplies water automatically, water is always in the water pipe, the pump body can spray when being started, and water in the water pipe cannot flow back after the water tap is closed;

when the water bucket is connected with self-priming water supply, the pump body is used for actively sucking water, and when the pump body is powered off, the water in the water pipe can not flow back, because the water in the inner sleeve pipe presses the inclined plane at the top of the rubber cap to block the slit.

1, a water gun; 1-1 middle handle; 2, inner sleeve; 2-1 annular step; 3, a side pipe; the side of 4 is opened; 5, opening at the lower part; 6 a rubber cap; 7 clamping part; 8, a bevel; 9, fine sewing; 10, a cap peak; 11 external connecting piece

Detailed Description

The invention is further described with reference to the following figures and examples.

As shown in figures 1-2, the rear portion of the water gun 1 is a rear handle, the middle portion of the water gun is provided with a middle handle 1-1, the water gun comprises an inner sleeve 2, a clamping portion 7 is arranged outside the inner sleeve 2, a clamping groove is arranged in the middle handle 1-1, the middle handle 1-1 is composed of a shell which can be opened and closed, and the clamping portion 7 of the inner sleeve 2 is limited in the clamping groove.

The upper end of the inner sleeve 2 is blocked, and only the lower opening 5 and the side opening 4 are arranged, wherein the side opening 4 is connected with the side pipe 3, and the side pipe 3 is connected with the plunger type pump body at the head part of the water gun 1. The lower opening 5 is provided with annular steps 2-1, the lower opening 5 is in threaded connection with an external connecting piece 11, a check valve is arranged in the lower opening 5, the check valve is an integrated rubber cap 6, a circle of brim 10 is arranged below the rubber cap 6, the brim 10 is clamped between the external connecting piece 11 and the annular steps 2-1 of the lower opening 5 of the inner sleeve 2, a cap body of the rubber cap 6 is arranged in the inner sleeve 2, the top of the cap body is provided with a slit 9, the outer surface of the top is an inclined surface 8, and the inclined surface 8 extends downwards from the slit 9. The top of the cap body is provided with two inclined surfaces 8, the two inclined surfaces 8 clamp the slit 9 in the middle, and the section of the top of the cap body, which is vertical to the slit 9, forms a triangular chamfer.

The water pipe is connected with the external connecting piece 11, so that the water pipe is connected below the middle handle, and the holding swing is more in line with the holding habit.

The water pipe is mainly connected with a water bucket and a tap water faucet,

when the water pipe is connected with the water tap, the water tap supplies water automatically, water is always in the water pipe, the pump body can spray when being started, and water in the water pipe cannot flow back after the water tap is closed, so that the rubber cap 6 does not have an effect at the moment.

The water pipe is connected with the water barrel, water is sucked by the pump body actively when self-priming water supply is carried out, air flow enters the pump body when the pump body is powered off, and water in the water pipe flows back into the barrel if no plug is arranged, so that the rubber cap 6 is arranged as a one-way valve, the water in the inner sleeve 2 presses the inclined plane 8 at the top of the rubber cap 6, and the slit 9 is plugged. The structure can completely realize the design purpose and has very low cost.

The valve is intake when the plunger pump motor starts, and the valve is also in synchronous relation.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
