As shown in Figure 9, the high-pressure air inlet pipe 6 includes a high-pressure gas inlet 61 and a high-pressure gas outlet 60. The high-pressure gas inlet 61 is connected to a high-pressure gas source, and the high-pressure gas source adopts conventional high-pressure air. It can be realized by using high-pressure air whose air pressure is 0.5-0.8Mpa, which is well known to those skilled in the art. A switch is not necessarily required, because the switch can be set on the high-pressure gas source, and of course, the switch 62 can also be set on the high-pressure air intake pipe; it is further used to control the input of the high-pressure gas source. Obviously, when the high-pressure gas inlet 61 is connected to the high-pressure gas source, it is best to ensure its airtightness, so as not to leak gas from there. Generally, an annular groove can be set at the entrance, and a sealing gasket can be set in the groove to achieve sealing. This method can also be used for the high-pressure gas outlet. For those skilled in the art, it is obviously easy to implement and use other alternative means to seal , so not much description.

The suction pipe is shown in Figure 3. In this example, the suction pipe 1 is a cylindrical tube, the front end 11 is the inlet of the suctioned object, the rear end 10 is the outlet of the suctioned object, and the front end 11 is bent at an obtuse angle near the middle. Certainly also can adopt straight pipe form, adopt the shape of bending in this example to facilitate manual operation. Its bore diameter is 12mm. The rear end 10 is fitted to the second gas inlet 20 of the manifold 2 with which the suction pipe 1 is thus in communication. The suction pipe 1 adopts a pvc pipe, that is, a polyvinyl chloride pipe, and the pvc pipe is well known in the art.

As shown in Figure 4, the confluence 2 is made of duralumin material and has a first gas inlet 22, a second gas inlet 20, and a confluence gas outlet 21. The confluence 2 is a cylindrical tubular shape, and the confluence is installed on In the valve body, an annular cavity 23 is formed between the valve body and the outer wall of the confluence. The annular cavity 23 communicates with the first gas inlet 22, and introduces the high-pressure gas from the high-pressure inlet pipe 6 into the first gas inlet 22. . In this way, due to the action of the high-pressure gas, a negative pressure will be formed at the gas outlet 21 of the confluence, so that a negative pressure will be generated at the second gas inlet 20 of the confluence 2 and in the suction pipe 1, so that the aspirated material will be sucked into the confluence 2, and then discharged from the manifold gas outlet 21 of the manifold 2.

Through the suction gun of the utility model, the aspirated object can be sucked out successfully. When in use, high-pressure gas is passed into the high-pressure intake pipe. After the high-pressure gas enters the confluence, negative pressure will be generated in the suction pipe, so the aspirated material is successfully sucked into the suction pipe, and then enters the confluence from the suction pipe. , and then discharged from the gas outlet of the manifold.

Preferably, as shown in FIG. 5 , a confluence auxiliary device 3 is also provided in the valve body of the suction gun. The confluence auxiliary device 3 is made of duralumin material and is a tubular object. The confluence auxiliary device 3 includes a confluence auxiliary device gas inlet 30 The gas outlet 31 of the confluence assistant is connected to the gas outlet 21 of the confluence assistant. The gas outlet 31 of the confluence assistant is used to discharge the gas and the sucked matter entering the confluence assistant 3 .

Preferably, a through hole 43 is also provided on the valve body 4, and the through hole is arranged between the high-pressure inlet pipe 6 and the first gas inlet 22 of the manifold 2; The first gas inlet of the trachea and the confluence is inconvenient, so first drill a hole through 43 from the surface of the valve body. At this time, the high-pressure intake pipe and the confluence can be easily connected, and then a block is provided in the through hole 43 near the surface of the valve body. Head 521 for sealing.

The valve body will now be described in detail, and the valve body is formed by machining duralumin. Referring to Fig. 6 and Fig. 7, the valve body 4 in this example is roughly in the shape of a cuboid. A confluence 2 is installed at 40, and a confluence auxiliary device 3 is installed at 41 outlets of the horizontal holes.

In the vertical direction of the horizontal hole, a through hole 43 is provided to communicate with the above-mentioned horizontal hole, and a high-pressure air intake pipe installation hole 42 is provided in a direction perpendicular to the through hole 43 and parallel to the horizontal hole; the high-pressure air intake pipe installation hole 42 is used To install the high-pressure intake pipe 6; the through hole 43 is provided with a plug 521 near the surface of the valve body,

As shown in Figure 8, the handle 5 is folded into " "shape, is designed for the convenience of carrying and holding the suction gun; includes a horizontal installation part 52, a connection part 51, and a hand grip part 50; the horizontal installation part 52 is parallel to the hand grip part 50, and is connected with the connection part 51 The horizontal installation part 52 is installed on the valve body 4 through the hole 520, and a small hole 500 is also provided on the handle part 50, which can be used for hanging and placing.

Of course, the handle can also be slightly more complicated, and be made into a manual switch to control the on-off of the high-pressure air source. Those skilled in the art are familiar with the implementation method of this technology, so no more description will be given.

Preferably, as shown in Fig. 1 and Fig. 10, a cloth bag 7 is also provided at the outlet of the confluence auxiliary device, and the cloth bag 7 is used to collect the aspirated matter. Cloth bag 7 is made with dense cloth and gets final product.

As shown in Fig. 11 and Fig. 12, the cloth bag clamping pipe is a circular long strip pipe with a gap in section, through which the opening of the cloth bag can be clamped. The cloth bag can be used to hold the absorbed substance sucked into it, so as to prevent the absorbed substance from being randomly distributed into the air and polluting the environment again. And the cloth bag can be opened and cleaned, easy to replace.

The use process is described as follows: as shown in Figure 1 and Figure 13, when using, turn on the switch of the high-pressure gas source, and then turn on the switch 62, then the high-pressure gas moves in the direction indicated by the arrow in the upper part of the figure, and first passes through the high-pressure intake pipe 6, Then enter the through hole 43, and then enter the first gas inlet 22 from the annular gap 23 of the confluence 2 communicated with the through hole 43, then enter the confluence auxiliary device 3, and finally enter the cloth bag 7 from the confluence auxiliary device.
