Description

Technical Field

[0001] This application relates to the technical field of spray painting devices, and more specifically to a bottom-lifting, no-wash paint sprayer. Background Technology

[0002] As a component of the spray gun, the paint can is mainly used to hold paint and supply paint to the spray gun, which then disperses the paint into a mist and sprays it onto the surface of the object being coated.

[0003] Currently, existing spray paint cans generally consist of an inner can, an outer can, and a lid. The inner can is placed inside the outer can, and the lid tightly seals the outer can, with a connector attached to the lid. During use, the paint in the inner can is drawn out and atomized by the external force of the spray gun. As the paint flows out, the amount of paint remaining in the inner can decreases, internal air is drawn out, and the remaining paint in the inner can is not easily extracted, thus affecting the uniformity and atomization of the paint, resulting in an unsightly painted surface.

[0004] Regarding the aforementioned technologies, the inventors believe that as the paint flows out, the amount of paint remaining in the inner container decreases, and the internal air is extracted. However, the paint in the inner container is not easily extracted, which has the defect of affecting the uniformity and atomization effect of the paint spraying, resulting in an unsightly painted surface. Utility Model Content

[0005] To alleviate the problem of reduced air inside the paint sprayer affecting the painting effect, this application provides a bottom-lifting, no-wash paint sprayer.

[0006] This application provides a bottom-lifting, no-wash paint sprayer, which adopts the following technical solution: A bottom-opening, no-wash paint spray bottle includes a bottle body and a flip-type switch mechanism. An air inlet is located at the bottom of the bottle body near the edge. The flip-type switch mechanism is connected to the bottom of the bottle body and controls the opening and closing of the air inlet. The flip-type switch mechanism includes a connecting boss and a flip plug. The connecting boss is fixedly connected to the bottle body and has a connecting hole. The connecting boss is cylindrical, and the connecting hole is coaxially arranged with the connecting boss, away from the air inlet. One end of the air vent is frustoconical, and the end of the connecting hole near the air inlet is cylindrical. The diameter of the connecting hole at the end away from the air inlet is larger than the diameter at the end near the air inlet. The lifting plug includes a connecting part, a bending part, and a plug body. The connecting part is fixedly connected to the kettle body via a fixing post. One end of the bending part is fixedly connected to the connecting part, and the other end of the bending part is fixedly connected to the plug body. The connecting part and the bending part are flexible components, and a bending groove is provided between the connecting part and the bending part. The plug body is used to seal the end of the connecting hole away from the air inlet.

[0007] By adopting the above technical solution, when the paint spraying pot body contains paint, the flip - type switch mechanism controls the air inlet hole to close, preventing the paint from flowing out; during use, the paint spraying pot body is connected and fixed to the pot lid and the spray gun, and the paint spraying pot body is in an inverted state. At this time, the flip - type switch mechanism is on top and the pot body is at the bottom. The flip - type switch mechanism opens the air inlet hole, starts the spray gun, and part of the air and paint in the pot body are sucked out. The air pressure inside the paint spraying pot body is less than the external air pressure, and the external air enters the pot body through the air inlet hole. Under the external action of the spray gun, the paint in the paint spraying pot body is discharged smoothly and evenly, alleviating the problem that the paint spraying effect is affected due to the reduction of air in the paint spraying pot; in addition, during the paint spraying process, the pot body is likely to tilt. By setting the air inlet hole at a position near the edge of the bottom of the pot body, the possibility that the paint in the pot body enters the flip - type switch mechanism or flows out of the pot body is reduced; furthermore, the connection boss away from the air inlet hole is sealed by the flip - plug, and the end of the communication hole away from the air inlet hole is designed as a frustum of a cone. When the plug body presses towards the conical hole opening, the conical surface can guide the plug body to be automatically centered, so that the plug body inserts into the cylindrical area of the communication hole, thereby closing the air inlet hole. Even if there are minor assembly deviations or wear, good contact can be maintained; when the air inlet hole needs to be opened, the flip - plug is lifted to make the flip - plug脱出 from the cylindrical area of the communication hole, and the plug body overlaps on the frustum - shaped area of the communication hole under the action of the bending part. The external air enters the communication hole through the gap between the flip - plug and the inner wall of the frustum - shaped area of the communication hole, while alleviating the problem that the paint spraying effect is affected due to the reduction of air in the paint spraying pot, reducing the possibility that foreign objects enter the pot body through the air inlet hole.

[0008] Optionally, three fixing columns are provided, and the three fixing columns are arranged in a "pin" shape. The connecting part is penetrated through the fixing columns, and a stop block for preventing the connecting part from脱出 is provided at one end of the fixing column away from the bottom of the pot body.

[0009] Optionally, the plug body includes a pressing plate and a plug. The pressing plate is fixedly connected to the connecting part, the plug is fixedly connected to the pressing plate, and the plug is in interference fit with the cylindrical area of the communication hole.

[0010] By adopting the above technical solution, the plug is in interference fit with the cylindrical area of the communication hole. The aperture of the communication hole at the end away from the air inlet hole is larger than that at the end close to the air inlet hole. The plug overlaps on the frustum - shaped area of the communication hole under the action of the bending part, and the external air enters the communication hole through the gap between the side wall of the plug and the inner wall of the frustum - shaped area of the communication hole.

[0011] Optionally, anti - slip lines are provided on one side of the pressing plate away from the plug.

[0012] By adopting the above technical solution, anti - slip lines are provided on the pressing plate, improving the convenience of using the flip - plug.

[0013] Optionally, the pressure plate and the plug are integrally formed.

[0014] Optionally, a support portion is provided at the bottom of the kettle body. The support portion has a ring-shaped structure, and the flip-type switch mechanism is located inside the support portion.

[0015] By adopting the above technical solution, a support part is set at the bottom of the pot body. The support part supports the space at the bottom of the pot body to accommodate the flip-type switch mechanism, so that the pot body can be placed stably on the table, improving the convenience of using the pot body.

[0016] Optionally, the support portion is integrally formed with the pot body.

[0017] Optionally, a venting groove is provided on the inner wall of the connecting boss, and the venting groove is provided along the generatrix direction of the frustum-shaped region of the connecting hole.

[0018] By adopting the above technical solution, a ventilation groove is opened on the inner wall of the connecting boss. When the plug blocks the cylindrical area of ​​the connecting hole away from the air inlet under the action of air pressure during the painting process, air can still enter the pot body through the ventilation groove and the air inlet, thereby improving the stability of the painting effect.

[0019] Optionally, multiple ventilation slots are provided, and the multiple ventilation slots are provided along the circumference of the connecting hole.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. When the paint can is filled with paint, the flip-type switch mechanism closes the air inlet to prevent paint from flowing out. During use, the paint can is connected and secured to the lid and spray gun, with the can inverted position (flip-type switch mechanism on top, can body below). The flip-type switch mechanism opens the air inlet, and the spray gun is activated. Some air and paint are drawn out of the can. The internal air pressure of the paint can is lower than the external air pressure, allowing external air to enter through the air inlet. The external action of the spray gun ensures that the paint in the can is smoothly and evenly discharged, mitigating the problem of reduced air volume affecting the painting effect. Furthermore, during the painting process, the can inevitably tilt. By placing the air inlet near the bottom edge of the can, the possibility of paint entering the flip-type switch mechanism or flowing out of the can is reduced. 2. By using a lifting plug to seal the end of the connecting boss away from the air inlet, and designing the end of the connecting hole away from the air inlet as a frustum, when the plug body is pressed against the conical orifice, the conical surface guides the plug body to automatically center itself, allowing the plug body to insert into the cylindrical area of ​​the connecting hole, thereby sealing the air inlet. Even with minor assembly deviations or wear, good contact can be maintained. When it is necessary to open the air inlet, the lifting plug is lifted to disengage it from the cylindrical area inside the connecting hole. The plug body overlaps the frustum-shaped area of ​​the connecting hole under the action of the bending part. External air enters the connecting hole through the gap between the lifting plug and the inner wall of the frustum-shaped area of ​​the connecting hole. This not only alleviates the impact of reduced air in the paint can on the painting effect, but also reduces the possibility of foreign objects entering the can through the air inlet. 3. By opening a ventilation groove on the inner wall of the connecting boss, when the plug blocks the end of the cylindrical area of ​​the connecting hole away from the air inlet under the action of air pressure during the painting process, air can still enter the pot body through the ventilation groove and the air inlet, thus improving the stability of the painting effect.

Detailed Implementation

[0023] To more clearly illustrate the overall concept of this application, the following is in conjunction with the appendix. Figure 1-5 This application will be described in further detail.

[0024] Exemplary embodiments of this application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are for teaching those skilled in the art how to implement this application only, and are not intended to exhaustively describe all possible methods of this application, nor to limit the scope of this application.

[0025] The technical solution of this application and how it solves the above-mentioned technical problems will be described in detail below with specific embodiments. It should be noted that, unless otherwise specified, the following embodiments can be referenced, learned from, or combined with each other. The same terms, similar features, and similar implementation steps in different embodiments will not be described again.

[0026] This application discloses a bottom-lifting, no-wash paint sprayer. (See also...) Figure 1 and Figure 2 A bottom-opening, no-wash paint sprayer includes a sprayer body 100 and a flip-type switch mechanism 200. An air inlet 110 is located at the bottom of the sprayer body 100 near the edge. The flip-type switch mechanism 200 is connected to the bottom of the sprayer body 100 and is used to control the opening and closing of the air inlet 110.

[0027] When the paint can body 100 is filled with paint, the flip-type switch mechanism 200 closes the air inlet 110 to prevent paint from flowing out. In use, the paint can body 100 is connected and fixed to the can lid and spray gun, with the paint can body 100 in an inverted position (flip-type switch mechanism 200 on top, can body 100 on the bottom). The flip-type switch mechanism 200 opens the air inlet 110, and the spray gun is activated. Some air and paint inside the can body 100 are drawn out. The internal air pressure of the paint can body 100 is lower than the external air pressure, allowing external air to enter the can body 100 through the air inlet 110. Under the external action of the spray gun, the paint inside the paint can body 100 is smoothly and evenly discharged, alleviating the problem of reduced air inside the paint can affecting the painting effect.

[0028] In addition, during the painting process, the paint container 100 will inevitably tilt. By setting the air inlet 110 at the bottom of the paint container 100 near the edge, the possibility of paint in the paint container 100 entering the flip-type switch mechanism 200 or flowing out of the paint container 100 is reduced.

[0029] Reference Figure 2 and Figure 3 The bottom of the kettle body 100 is provided with a support part 120, which is a ring structure. The flip-type switch mechanism 200 is located inside the support part 120. The support part 120 and the kettle body 100 are integrally formed.

[0030] By providing a support portion 120 at the bottom of the kettle body 100, the support portion 120 is used to prop up the space at the bottom of the kettle body 100 to accommodate the flip-type switch mechanism 200, so that the kettle body 100 can be stably placed on the table, improving the convenience of using the kettle body 100.

[0031] Refer to Figure 2 and Figure 4 As shown in FIGS. and, the flip-type switch mechanism 200 includes a connecting boss 210 and a flip plug 220. The connecting boss 210 is fixedly connected to the kettle body 100. A communication hole 211 is provided on the connecting boss 210. The connecting boss 210 has a cylindrical structure, and the communication hole 211 is coaxially arranged with the connecting boss 210. One end of the communication hole 211 away from the air inlet hole 110 is frustum-shaped, and one end of the communication hole 211 close to the air inlet hole 110 is cylindrical. The aperture of the communication hole 211 at the end away from the air inlet hole 110 is larger than the aperture at the end close to the air inlet hole 110. The flip plug 220 includes a connecting portion 221, a bending portion 222 and a plug body portion 223. The connecting portion 221 is fixedly connected to the kettle body 100 through a fixing column 225. One end of the bending portion 222 is fixedly connected to the connecting portion 221, and the other end of the bending portion 222 is fixedly connected to the plug body portion 223. The connecting portion 221 and the bending portion 222 are flexible members, and a bending groove 224 is provided between the connecting portion 221 and the bending portion 222. The plug body portion 223 is used to block one end of the communication hole 211 away from the air inlet hole 110.

[0032] The flip plug 220 closes one end of the connecting boss 210 away from the air inlet hole 110. One end of the communication hole 211 away from the air inlet hole 110 is designed to be frustum-shaped. When the plug body portion 223 presses against the conical hole opening, the conical surface can guide the plug body portion 223 to automatically center, so that the plug body portion 223 is inserted into the cylindrical area of the communication hole 211, thereby closing the air inlet hole 110. Even if there are minor assembly deviations or wear, good contact can be maintained. When the air inlet hole 110 needs to be opened, the flip plug 220 is lifted to make the flip plug 220脱出 from the cylindrical area inside the communication hole 211. The plug body portion 223 is lapped on the frustum-shaped area of the communication hole 211 under the action of the bending portion 222. External air enters the communication hole 211 through the gap between the flip plug 220 and the inner wall of the frustum-shaped area of the communication hole 211. While alleviating the influence on the painting effect due to the reduction of air in the paint spray kettle, the possibility of foreign objects entering the kettle body 100 through the air inlet hole 110 is reduced.

[0033] Refer to Figure 2 As shown in FIG., three fixing columns 225 are provided. The three fixing columns 225 are arranged in a "pin" shape. The connecting portion 221 is inserted through the fixing columns 225, and a stop block for preventing the connecting portion 221 from脱出 is provided at one end of the fixing columns 225 away from the bottom of the kettle body 100.

[0034] Refer to Figure 2 and Figure 4 The plug body 223 includes a pressing plate 226 and a plug 227. The pressing plate 226 is fixedly connected to the connecting part 221, and the plug 227 is fixedly connected to the pressing plate 226. The plug 227 is interference-fitted with the cylindrical area of ​​the connecting hole 211. The diameter of the connecting hole 211 at the end away from the air inlet 110 is larger than the diameter at the end closer to the air inlet 110. Under the action of the bending part 222, the plug 227 overlaps the frustum-shaped area of ​​the connecting hole 211. External air enters the connecting hole 211 through the gap between the side wall of the plug 227 and the inner wall of the frustum-shaped area of ​​the connecting hole 211.

[0035] Reference Figure 4 The pressure plate 226 has anti-slip texture 228 on the side away from the plug 227, and the pressure plate 226 and the plug 227 are integrally formed. By creating anti-slip texture 228 on the pressure plate 226, the ease of use of the lifting plug 220 is improved.

[0036] Reference Figure 5 In another preferred embodiment, a venting groove 212 is provided on the inner wall of the connecting boss 210, and the venting groove 212 is provided along the generatrix direction of the frustum-shaped region of the connecting hole 211. By providing a venting groove 212 on the inner wall of the connecting boss 210, when the plug 227 blocks the end of the cylindrical region of the connecting hole 211 away from the air inlet 110 under the action of air pressure during the painting process, air can still enter the interior of the pot body 100 through the venting groove 212 and the air inlet 110, thereby improving the stability of the painting effect.

[0037] In another preferred embodiment, multiple ventilation slots 212 are provided, and the multiple ventilation slots 212 are provided circumferentially along the connecting hole 211.

[0038] For any parts not mentioned in this application, existing technologies may be used or referenced.
