Description

Technical Field

[0001] This utility model relates to the field of spray equipment technology, and in particular to an anti-clogging sprayer with a filtration function. Background Technology

[0002] A sprayer is a very practical tool that uses the principle of air suction to convert liquid into fine mist particles and spray them evenly. This device has been widely used in many fields, including but not limited to sanitation and epidemic prevention, irrigation and fertilization in agricultural planting, pest and disease control of fruit and vegetable crops, and disinfection and cleaning in homes and public places. The use of sprayers has greatly improved work efficiency and brought convenience to people's lives.

[0003] Existing electric sprayers no longer use lead-acid batteries, which are prone to causing environmental pollution, as their power source. Instead, they use lithium batteries. The lithium batteries in lithium-ion sprayers are fixed to the sprayer housing, making charging inconvenient and requiring the sprayer to be fully charged before use, thus affecting work efficiency. To address these issues, Chinese patent CN214234680U discloses an electric sprayer that increases overall structural strength and reduces the likelihood of deformation by adding a lower support bracket to securely connect the liquid tank and housing components. The non-parallel design of the support bracket to the ground also prevents the sprayer from tipping over on slopes, improving safety. Furthermore, the pump is integrated into the liquid tank using a blow-molded insert, saving internal space and allowing the liquid to help dissipate heat, extending the pump's lifespan. The battery pack is detachably connected to the housing components, and the inclusion of elastic components and an inverted structure facilitates battery pack replacement, improving work efficiency. Finally, drainage channels and sealing rings on the housing components enhance the sprayer's safety for outdoor use.

[0004] A pump is used to effectively transfer the liquid medicine from the medicine tank to the spray gun assembly for spraying operations. However, after a period of use, some liquid medicine will inevitably adhere to the inner wall of the spray gun assembly. As the ambient temperature changes, the water in the liquid medicine will gradually evaporate, leaving behind the solid components. This powder will gradually accumulate on the inner wall and eventually adhere to the inner wall of the spray gun assembly. This will not only cause the nozzles on the spray gun assembly to become clogged, but also affect the efficiency and quality of the spraying operation. Utility Model Content

[0033] Reference Figure 1-5 This utility model provides an embodiment of an anti-clogging sprayer with a filtration function, comprising a tank 1, a delivery hose 2 passing through the center of the bottom of the tank 1. It is worth noting that the delivery hose 2 can be bent but cannot be extended or retracted. A placement ring 3 is fixedly connected to one outer wall of the tank 1. A pump body 4 is sleeved on the top of the inner wall of the placement ring 3. The inlet of the pump body 4 is threadedly connected to the top of the delivery hose 2. A nozzle 5 is fixedly connected to the outlet of the pump body 4. When using the sprayer, the pump body 4 can be removed from the placement ring 3, and then the nozzle 5 can be aligned with the designated direction. At the same time, the pump body 4 is turned on, and the solution in the tank 1 will then enter the pump body 4 along the delivery hose 2 and finally be sprayed out from the nozzle 5.

[0034] A filter ring 6 is fixedly connected to the bottom of the inner wall of the tank 1. By setting the filter ring 6, the solution in the tank 1 can be filtered, thereby intercepting the solid raw materials mixed in the solution. A top ring 7 is fixedly connected to the top of the filter ring 6, and an outer ring 8 is fixedly connected to the top of the top ring 7. A rotating ring 9 is rotatably connected to the inner wall of the outer ring 8. An L-shaped scraper 10 is fixedly connected to the top of the outer wall of the rotating ring 9. The concave surface of the L-shaped scraper 10 can rotate closely against the outer wall of the filter ring 6, which can remove the solid raw materials attached to the surface of the filter ring 6, thereby avoiding the clogging of the filter ring 6 structure.

[0035] A through-hole 11 is provided at the center of the top of the tank 1. A reversible motor 12 is fixedly connected to the top of the inner wall of the through-hole 11.
