[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-9 The utility model is a sandblasting and cleaning mobile phone with convenient adjustment of sand output amount, comprising a nozzle 1, a body 2 and a sand box 3. The nozzle 1 and the body 2 are detachably connected, the sand box 3 is arranged on the body 2, and the sand box 3 is provided with an air inlet hole 3.1 and a sand outlet hole 3.2. The sand box 3 is a hollow cylindrical shape, and an air inlet pipe 4, a water pipe 5 and a sand outlet pipe 6 are arranged in the body 2. The air inlet pipe 4 and the sand outlet pipe 6 are connected to the sand box 3 through the air inlet hole 3.1 and the sand outlet hole 3.2 respectively. The sand outlet pipe 6 is inserted into the sand outlet hole 3.2 from the outside of the sand box 3, and the sand outlet pipe 6 does not protrude from the inner wall of the sand box 3. The sand box 3 is provided with a sand discharge adjustment mechanism, which includes an adjusting ring 7, an adjusting plate 10 and a limiting mechanism. The adjusting ring 7 is movably sleeved on the outer wall of the sand box 3 and limited by the limiting mechanism. A transverse through groove 3.3 is provided on the side wall of the sand box 3 corresponding to the adjusting ring 7. The adjusting plate 10 is movably provided on the inner wall of the sand box 3 at the sand discharge hole 3.2 and the through groove 3.3. An adjusting rod 12 is connected between the adjusting ring 7 and the adjusting plate 10. The adjusting rod 12 passes through the through groove 3.3 and can slide in the through groove 3.3 under the drive of the adjusting ring 7. Driven by the adjusting rod 12, part of the area of ​​the adjusting plate 10 always covers the through groove 3.3, and another part of the area of ​​the adjusting plate 10 does not cover the sand discharge hole 3.2 or can cover part of the sand discharge hole 3.2, and a sealing device is provided between the adjusting plate 10 and the through groove 3.3.

[0024] When the utility model is implemented, the limiting mechanism includes a supporting ring plate 8 and a limiting plate 11. The supporting ring plate 8 is provided on the outer wall of the sand box 3, and the adjusting ring 7 is provided on the supporting ring plate 8. The lower end of the adjusting ring 7 is provided with a plurality of upper grooves 7.1, and the upper grooves 7.1 open downward. The upper end of the supporting ring plate 8 is provided with an adaptive lower groove, and the lower groove opens upward. After the adjusting ring 7 is rotated, the upper groove 7.1 and the lower groove are aligned, and the limiting plate 11 is inserted into the aligned upper groove 7.1 and the lower groove, which is used to limit the adjusting ring 7 to the supporting ring plate 8. Every time the adjusting ring 7 is rotated to an upper groove 7.1 and a lower groove are aligned, the corresponding adjusting plate 10 adjusts the sand outlet hole 3.2. The range of the upper groove 7.1 is consistent with the range of the through groove 3.3, that is, the adjusting ring 7 is adjusted When the upper groove 7.1 at the outermost end is aligned with the lower groove, the adjusting rod 12 slides at the outermost end of the through groove 3.3, and the through groove 3.3 is located above the sand outlet hole 3.2. The adjusting plate 10 is T-shaped, and the area of ​​the through groove 3.3 covered by the adjusting plate 10 is much larger than the area of ​​the through groove 3.3, that is, the area of ​​the upper part of the T is much larger than the area of ​​the through groove 3.3, so that when the adjusting rod 12 slides in the through groove 3.3, the adjusting plate 10 always covers the through groove 3.3 to prevent sand powder from leaking out. Sealing strips are provided on the inner walls of the sand box 3 corresponding to the upper, lower, left and right sides of the through groove 3.3. The sealing strips are between the inner wall of the sand box 3 and the adjusting plate 10. The sealing strips on the left and right sides have a slide groove of a certain length to facilitate sealing when the adjustment plate moves.

[0025] In the specific implementation of the present invention, the portion of the adjusting rod 12 located in the through slot 3.3 is a smooth rod, and the two ends of the adjusting rod 12 are threaded rods. The threaded rods at both ends cooperate with nuts to connect with the adjusting ring 7 and the adjusting plate 10. This structure can achieve a detachable connection, and can also adjust the distance between the adjusting ring 7 and the adjusting plate 10 so that the adjusting ring 7 and the adjusting plate 10 fit the outer wall and the inner wall of the flask 3 as closely as possible. A needle roller or steel ball 13 is provided on the surface of the adjusting ring 7 facing the flask 3. The needle roller or steel ball 13 rolls on the outer wall of the flask 3 to facilitate the rotation of the adjusting ring 7. The outer wall of the adjusting ring 7 is provided with friction stripes 9, which can be more easily driven.

[0026] When the utility model is working, gas enters the sand box through the air inlet pipe in the machine body, raising sand powder, and the sand powder is transported to the nozzle through the sand outlet pipe to merge with the water in the water inlet pipe and sprayed out. When the amount of sand output needs to be adjusted, the adjusting ring is rotated, and the adjusting ring drives the adjusting plate to adjust the cross-section of the sand outlet hole through the adjusting rod, thereby achieving the purpose of adjusting the amount of sand output. The utility model is simple and convenient to operate and can improve work efficiency.
