[0016] Preferably, a side of the clamping frame away from the driving rod is fixedly connected with an anti-skid pad, and the material of the anti-skid pad is rubber.

[0017] The effects achieved by the above components are as follows: the anti-skid pad achieves the effect of increasing the friction with the arc surface of the spray rod, while improving the stability of the device.

[0018] Preferably, a positioning rod is fixedly connected to one side of the clamping frame close to the driving rod, and the arc surface of the positioning rod is slidably connected to the connecting plate.

By setting the protective device 3, the effect of shielding the returned mist is achieved, and it is avoided that when the staff uses the sprayer body 1, the mist sprayed by the spray rod 2 is blown back by the reverse wind, causing the mist to flow back to the body surface of the staff, thereby affecting the safety of the staff, and improving the protection of the device. The arc surface of the spray rod 2 is provided with a clamping device 4. By setting the clamping device 4, the effect of adjusting the position of the folded cloth 301 is achieved, and it is avoided that when the spray angle of the spray rod 2 is different, the returned mist spreads, and the folded cloth 301 at a close distance is difficult to completely shield the returned mist, resulting in a reduction in the protective effect of the folded cloth 301, thereby improving the practicality of the device.

[0029] The specific arrangement and function of the protection device 3 and the clamping device 4 will be described in detail below.

[0030] Reference Figure 2 and Figure 3As shown, in this embodiment: the protective device 3 includes a folded cloth 301, the folded cloth 301 is slidably connected to the arc surface of the spray rod 2, the material of the folded cloth 301 is TPR material, one end of the folded cloth 301 is fixedly connected to a strip block 302, the end of the folded cloth 301 away from the strip block 302 is fixedly connected to a fixed block 303, the surface of the fixed block 303 is fixedly connected to a fixed rod 304, the arc surface of the fixed rod 304 is slidably connected to an operating panel 305, the side of the operating panel 305 close to the fixed block 303 is fixedly connected to an insertion rod 306, the surface of the strip block 302 is fixedly connected to a fixed rod 304, and the surface of the fixed rod 304 is fixedly connected to a fixed rod 306. The surface is provided with a slot, and the end of the fixing rod 304 away from the fixing block 303 is fixedly connected to the limiting plate 307. The size of the plug rod 306 is adapted to the size of the slot of the strip block 302. When the staff pulls the operating plate 305, the operating plate 305 slides on the arc surface of the fixing rod 304. At this time, the limiting plate 307 has the effect of limiting the maximum sliding distance of the operating plate 305 on the arc surface of the fixing rod 304, thereby avoiding the situation that when the staff pulls the operating plate 305, the operating plate 305 is separated from the arc surface of the fixing rod 304 due to excessive pulling force. The arc surface of the fixing rod 304 is sleeved with a first spring 308, and the two ends of the first spring 308 are fixedly connected to the operating plate 305 and the fixing block 303 respectively. When the staff releases the operating plate 305, the resilience of the first spring 308 drives the operating plate 305 to slide on the arc surface of the fixing rod 304, and at the same time, the operating plate 305 drives the insertion rod 306 to move until the insertion rod 306 is inserted into the slot of the strip block 302. At this time, the first spring 308 improves the stability of the insertion rod 306 when limiting the strip block 302, and the fixing block 303 is fixedly connected to the side close to the fixing rod 304 It is connected to a threaded rod 309, and the arc surface thread of the threaded rod 309 is connected to a support plate 310. When the staff releases the limit of the bar block 302 by the insertion rod 306, the operating plate 305 continues to be pulled until the operating plate 305 moves to the highest point of the fixed rod 304. At this time, the support plate 310 is rotated, and the support plate 310 moves on the arc surface thread of the threaded rod 309 until the support plate 310 moves below the operating plate 305. At this time, the support plate 310 has achieved the effect of limiting the movement of the operating plate 305, so that the staff can quickly disassemble and replace the folded cloth 301.

[0031] Reference Figure 4As shown, specifically, the clamping device 4 includes a circular plate 41, which is slidably connected to the arc surface of the spray rod 2, and two connecting plates 42 are fixedly connected to the lower surface of the circular plate 41. A driving rod 43 is inserted into the internal thread of the connecting plate 42, and one end of the driving rod 43 is rotatably connected to a clamping frame 44, and a side of the clamping frame 44 away from the driving rod 43 is fixedly connected to an anti-skid pad 45, and the material of the anti-skid pad 45 is rubber. When the staff rotates the driving rod 43, the driving rod 43 moves on the internal thread of the connecting plate 42, and at the same time, the driving rod 43 drives the clamping frame 44 to move, and the clamping frame 44 drives the anti-skid pad 45 to move until the anti-skid pad 45 is The sliding pad 45 abuts against the arc surface of the spray rod 2. At this time, the anti-skid pad 45 achieves the effect of increasing the friction with the arc surface of the spray rod 2, and at the same time improves the stability of the device. The clamping frame 44 is fixedly connected with a positioning rod 46 on the side close to the driving rod 43. The arc surface of the positioning rod 46 is slidably connected to the connecting plate 42. When the staff rotates the driving rod 43, the driving rod 43 moves in the inner thread of the connecting plate 42. At the same time, the driving rod 43 drives the clamping frame 44 to move, and the clamping frame 44 drives the positioning rod 46 to slide in the connecting plate 42. At this time, the positioning rod 46 achieves the effect of limiting the clamping frame 44 from rotating with the driving rod 43.

[0032] Working principle: when the staff needs to use the folding cloth 301 to block the backflow mist, the folding cloth 301 is pressed to make the folding cloth 301 slide with the arc surface of the spray rod 2. At this time, the strip block 302 is pulled, and the fixed block 303 is pulled at the same time, so that the strip block 302 and the fixed block 303 move in a circular direction toward each other. At the same time, the folding cloth 301 is stretched and supported into a circle. At this time, the operating plate 305 is pulled to make the operating plate 305 slide on the arc surface of the fixed rod 304, and the first spring 308 is stretched. At the same time, the operating plate 305 drives the insertion rod 306 to move until the insertion rod 306 no longer blocks the movement of the strip block 302. At this time, the operating plate 305 is continued to be pulled until the operating plate 305 moves to the highest point of the fixed rod 304. At this time, the support plate 310 is rotated, and the support plate 310 moves in a threaded manner on the arc surface of the threaded rod 309 , until the support plate 310 moves to the bottom of the operating plate 305, at this time, continue to pull the strip block 302 until the strip block 302 is fitted with the fixed block 303, at this time, rotate the support plate 310 again, and the support plate 310 moves on the arc surface of the threaded rod 309 until the support plate 310 is separated from the bottom of the operating plate 305, at this time, the resilience of the first spring 308 drives the operating plate 305 to slide on the arc surface of the fixed rod 304, and at the same time, the operating plate 305 drives the insertion rod 306 to move until the insertion rod 306 is inserted into the slot of the strip block 302, at this time, the effect of shielding the refluxed mist is achieved, avoiding that when the staff uses the sprayer body 1, the mist sprayed by the spray rod 2 is blown back by the reverse wind, causing the mist to flow back to the staff's body surface, thereby causing a situation that affects the safety of the staff, thereby improving the protection of the device.

[0033] When the staff needs to adjust the position of the folding cloth 301, the driving rod 43 is rotated, and the driving rod 43 moves in the inner thread of the connecting plate 42. At the same time, the driving rod 43 drives the clamping frame 44 to move, and the clamping frame 44 drives the positioning rod 46 to slide in the connecting plate 42. At the same time, the clamping frame 44 drives the anti-skid pad 45 to move until the anti-skid pad 45 no longer abuts against the arc surface of the spray rod 2. At this time, the circular plate 41 is pulled to make the circular plate 41 slide on the arc surface of the spray rod 2. At this time, the folding cloth 301 has a larger moving space. The folding cloth 301 continues to fit with the circular plate 41 due to gravity. At this time, the effect of adjusting the position of the folding cloth 301 is achieved, and the diffusion of the backflow mist when the spray angle of the spray rod 2 is different is avoided. The folding cloth 301 at a close distance is difficult to completely block the backflow mist, resulting in a reduction in the protective effect of the folding cloth 301, thereby improving the practicability of the device.
