[0002] Currently, spray guns are commonly used tools in industrial production and daily painting operations, but traditional spray guns have many problems. During spraying, the atomized paint easily scatters in all directions, resulting in paint waste, increased production costs, and pollution of the working environment, which can harm the health of workers, such as causing respiratory diseases. After the spray gun is turned off, the residual paint dripping from the nozzle cannot be effectively recovered, further causing resource waste. Utility Model Content
[0003] The purpose of this invention is to provide an energy-saving spray gun to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution, which includes a spray gun body, a mounting shell provided on the outer side of the nozzle of the spray gun body, a detachable anti-spray cover provided on the mounting shell, a mounting rod provided on the lower side of the handle of the spray gun body, a first C-shaped clamping ring provided at the front end of the mounting rod, the first C-shaped clamping ring cooperating with a second C-shaped clamping ring to clamp a residual paint collection tank, and connecting ears symmetrically provided on both sides of the first C-shaped clamping ring and the second C-shaped clamping ring, and the two fitting connecting ears are fixed together by a bolt group.
[0005] As a preferred embodiment of this utility model, the mounting shell has symmetrical mounting holes on its upper and lower sides, the anti-scattering cover has an insertion edge on its back side, the insertion edge is inserted into the mounting shell, the insertion edge has a fixing hole at the position corresponding to the mounting hole, and the corresponding mounting hole and fixing hole are fixed together by screws, the anti-scattering cover has a recycling tray at its bottom, and the recycling tray has an internal thread cap at its bottom.
[0006] As a preferred embodiment of this utility model, the top of the residual paint collection tank is provided with a threaded nozzle, the threaded nozzle being threaded into an internal thread cap; an observation port is provided on the outer wall of the residual paint collection tank, and a transparent plate is provided inside the observation port; a sealed bearing is provided at the bottom of the residual paint collection tank, and a rotating shaft is provided inside the sealed bearing; an array of stirring arms is provided on the wall of a section of the rotating shaft located inside the residual paint collection tank, and an array of stirring claws is provided on each stirring arm; a handle is provided at the top of the end of the rotating shaft located outside the residual paint collection tank.
[0007] As a preferred embodiment of this utility model, the top of the threaded nozzle is provided with several slots, each slot is provided with a positioning rod, and the top of the positioning rods is provided with a diversion baffle.
[0008] As a preferred embodiment of this invention, both the inner walls of the first C-shaped clamp and the second C-shaped clamp are provided with anti-slip textures.
[0009] As a preferred embodiment of this invention, both the anti-scattering cover and the residual paint collection tank are made of polytetrafluoroethylene.
[0010] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:
[0011] This invention effectively prevents atomized paint from scattering in all directions by installing a detachable anti-spray cover on the outer shell of the spray gun nozzle. The anti-spray cover is connected to the mounting shell by inserts, slots, and screws, making it securely installed and easy to disassemble and clean. During spraying, the atomized paint is intercepted by the anti-spray cover and falls onto its inner wall. Due to the non-stick properties of polytetrafluoroethylene, the paint flows into the recovery tray and then into the residual paint collection tank. This process greatly reduces paint waste caused by scattering, lowers production costs, and achieves energy-saving goals.
[0012] This invention connects a stirring arm and a stirring claw to a rotating shaft inside a sealed bearing at the bottom of a residual paint collection tank. A handle is installed on the top of the outer side. During long-term painting operations, operators can manually turn the handle at any time to rotate the stirring component and stir the residual paint in the tank, preventing the residual paint from solidifying. This provides convenience for the subsequent processing and reuse of the residual paint, reducing resource waste and processing costs.
[0013] This utility model uses a first C-shaped clamp and a second C-shaped clamp to clamp and fix the residual paint collection tank through connecting ears and bolts. The anti-slip texture on the inner wall of the C-shaped clamp increases friction, making the fixation more stable. The connection structure between the anti-scattering cover and the residual paint collection tank is simple, and installation and disassembly are easy, which facilitates daily maintenance, cleaning and component replacement, and improves work efficiency.
[0014] This invention uses polytetrafluoroethylene (PTFE) for the anti-spray cover and residual paint collection tank, which has the characteristics of non-stick, corrosion resistance, and high and low temperature resistance. The non-stick property makes it difficult for paint to adhere, making it easy to collect and clean; the corrosion resistance and high and low temperature resistance extend the service life of the components, reduce maintenance costs, and improve the overall performance of the spray gun.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0025] like Figures 1-8 As shown, this utility model proposes an energy-saving spray gun, which includes a spray gun body 1. A mounting shell 10 is provided on the outside of the nozzle of the spray gun body 1 to provide a basic structure for the installation of other components. A detachable anti-spray cover 2 is provided on the mounting shell 10 to effectively prevent atomized paint from scattering. A mounting rod 12 is provided below the front of the handle of the spray gun body 1. A first C-shaped clamping ring 13 is provided at the front end of the mounting rod 12. The first C-shaped clamping ring 13 cooperates with a second C-shaped clamping ring 15 to clamp the residual paint collection tank 3 for collecting residual paint generated during the operation. Connecting ears 14 are symmetrically provided on both sides of the first C-shaped clamping ring 13 and the second C-shaped clamping ring 15. The two connecting ears 14 that fit together are fixed together by a bolt group 4 to ensure a stable clamping of the residual paint collection tank 3.
[0026] Mounting holes 11 are symmetrically provided on the upper and lower sides of the mounting shell 10. The back of the anti-splash cover 2 is provided with an insert edge 20, which is inserted into the mounting shell 10. The insert edge 20 is provided with a fixing hole 22 corresponding to the mounting hole 11. The corresponding mounting hole 11 and fixing hole 22 are fixed together by screws 21. This structure makes the anti-splash cover 2 easy and firm to install, and easy to disassemble, clean or replace when needed. The bottom of the anti-splash cover 2 is provided with a recycling tray 23. The bottom of the recycling tray 23 is provided with an internal thread cap 24 for connecting the residual paint collection tank 3, so that the recycled paint can flow smoothly into the collection tank.
[0027] The top of the residual paint collection tank 3 is equipped with a threaded nozzle 32, which is threaded into an internal threaded cap 24 to achieve a tight connection with the recycling tray 23. An observation port 30 is provided on the outer wall of the residual paint collection tank 3, and a transparent plate 31 is provided inside the observation port 30 to facilitate the operator to observe the collection of residual paint in the tank at any time. A sealed bearing 34 is provided at the bottom of the residual paint collection tank 3, and a rotating shaft 35 is provided inside the sealed bearing 34. An array of stirring arms 36 is provided on the inner wall of the rotating shaft 35, and an array of stirring claws 37 is provided on each stirring arm 36. A handle 38 is provided at the top of the outer end of the rotating shaft 35. When it is necessary to prevent the residual paint from solidifying, the operator can manually turn the handle 38 to drive the rotating shaft 35, stirring arms 36 and stirring claws 37 to rotate and stir the residual paint in the tank.
[0028] The top of the threaded nozzle 32 has several slots 39, and each slot 39 is fitted with a positioning rod 6. The top of the positioning rods 6 is also provided with a diversion baffle 60. The diversion baffle 60 can divert the paint flowing into the threaded nozzle 32, so that it enters the residual paint collection tank 3 more evenly, improves the collection efficiency, and at the same time prevents external impurities from falling into the residual paint collection tank 3.
[0029] The inner walls of the first C-shaped clamping ring 13 and the second C-shaped clamping ring 15 are both provided with anti-slip textures 5, which increase the friction with the outer wall of the residual paint collection tank 3, further ensuring the stability of clamping and preventing the residual paint collection tank 3 from shaking or slipping during use.
[0030] Both the anti-spray cover 2 and the residual paint collection tank 3 are made of polytetrafluoroethylene (PTFE). PTFE has properties such as non-stick, corrosion resistance, and resistance to high and low temperatures, which makes it difficult for paint to adhere to the inner walls of the anti-spray cover 2 and the residual paint collection tank 3, facilitating the collection and cleaning of paint, and extending the service life of the components.
[0031] When installing the equipment, firstly, precisely align the insertion edge 20 of the anti-splash cover 2 with the slot 39 inside the mounting shell 10 and insert it smoothly. This step requires careful operation by the operator to ensure that the insertion edge 20 and the slot 39 are completely fitted without any deviation. Then, gently rotate the anti-splash cover 2 so that the fixing hole 22 is precisely aligned with the mounting hole 11, and then fix it with the screw 21. The tightness of the screw 21 should be moderate. Next, align the spiral nozzle on the top of the residual paint collection tank 3 with the internal thread cap 24 and slowly screw it in clockwise until it is tight, ensuring that the two are tightly connected and there is no leakage. Finally, fix the second C-shaped clamping ring 15 to the first C-shaped clamping ring 13 with the bolt group 4. The bolts should be tightened evenly to further clamp and fix the residual paint collection tank 3, ensuring that it is stable and reliable during use.
[0032] During daily use, the anti-spray cover 2 plays a crucial role when operators are spraying paint. It effectively prevents the sprayed atomized paint from scattering outwards, thereby reducing paint waste. The atomized paint will fall onto the inner wall of the anti-spray cover 2 under its obstruction. Since the anti-spray cover 2 is made of polytetrafluoroethylene, which has non-stick and smooth properties, when a lot of paint accumulates on the inner wall, the paint will converge under the action of gravity and flow into the recycling tray 23 along the inner wall of the anti-spray cover 2, and finally into the residual paint collection tank 3 for unified collection. Similarly, when the spray gun is closed after the spraying operation is completed, the residual paint dripping from the nozzle will also slide down the anti-spray cover 2 to the recycling tray 23 and be recycled, thus realizing the all-round recycling and utilization of residual paint.
[0033] During prolonged painting operations, to prevent the paint collected in the residual paint collection tank 3 from solidifying and affecting subsequent processing and use, operators can manually turn the handle 38 at any time. The handle 38 is connected to the rotating shaft 35. When the handle 38 is turned, the rotating shaft 35 will rotate accordingly, and the stirring arm 36 and stirring claw 37 fixed on the rotating shaft 35 will also rotate together to stir the paint. In this way, the fluidity of the paint is maintained, ensuring that the paint will not solidify due to prolonged standing, thus providing a guarantee for the continuous and efficient operation of the painting work.
[0034] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
