Description

Technical Field

[0001] This utility model relates to the field of paint spraying auxiliary equipment technology, and in particular to a paint spraying bottle assist mechanism. Background Technology

[0002] Spray paint cans, as a common painting tool, are widely used in various fields such as model making, small furniture refurbishment, automotive touch-up painting, industrial marking, and home DIY. Traditional spray paint cans rely on manual pressing of the nozzle by the operator. During prolonged, large-area spraying operations, the operator's fingers, especially the index finger and thumb, need to exert continuous force, easily leading to fatigue, soreness, and even spasms. This results in unstable spraying movements, affecting the uniformity of paint quality and significantly reducing work efficiency. To address these problems, some assistive devices have emerged on the market. These devices typically employ levers, gears, or clamping structures to reduce the pressure exerted by the operator's fingers through mechanical force amplification. For example, a Chinese utility model patent (patent application number: 201520945236.2) discloses a "hand spray gun" that amplifies the user's pressing force through a lever mechanism and transmits it to the spray nozzle of the paint can, thereby saving effort.

[0003] Existing paint assist mechanisms are too simplistic in function, their design intent and actual effect limited to the basic function of "assistance," failing to meet the increasingly diverse painting needs of users. For example, the nozzles of commercially available spray paint bottles are typically designed with a fixed mode, defaulting to spraying a cone-shaped mist of paint. This mist spraying is suitable for uniform coverage of large areas. However, in many specific work scenarios, such as drawing precise straight or thin lines on walls or floors for area division and marking, or precisely touching up small gaps and corners, mist spraying results in diffused paint mist, blurred boundaries, and extremely poor accuracy, failing to meet the work requirements. In other words, existing paint assist devices cannot simultaneously meet the needs for labor-saving and diversified painting modes. Summary of the Invention

[0004] The main purpose of this utility model is to provide a paint spray bottle assist mechanism, which aims to make the painting operation more labor-saving, while further expanding the painting modes and meeting the needs of different scenarios.

[0005] To achieve the above objectives, the present invention proposes a paint bottle assist mechanism, which is applied to a paint bottle. The paint bottle includes a bottle body and a nozzle connected together. The nozzle is provided with a first spray nozzle. The paint bottle assist mechanism includes: The outer shell is provided with a slot, and the bottle body can be snapped into the slot; A booster lever is rotatably connected to the housing. The booster lever has a force-applying end and a pressing end that are oppositely arranged, and the pressing end can abut against the surface of the nozzle; and The nozzle is detachably connected to the pressing end, and the nozzle is provided with a second nozzle that is connected to the first nozzle.

[0006] In an optional embodiment, the nozzle includes a tube body and a fixing seat. The fixing seat is detachably connected to the pressing end and has an insertion hole facing the first nozzle. The tube body is provided with a second nozzle and can be inserted into the insertion hole.

[0007] In an optional embodiment, the pressing end is provided with a fixing post, the fixing seat has a fixing hole, and the fixing post is sleeved in the fixing hole to connect the fixing seat and the pressing end.

[0008] In an optional embodiment, the sidewall of the fixing hole is provided with a plurality of spaced positioning ribs, the surface of the fixing post is provided with a plurality of positioning grooves, and the fixing seat is rotatable relative to the fixing post so that one of the positioning ribs is embedded in one of the positioning grooves.

[0009] In an optional embodiment, the fixing base includes a fixing ring, a base body, and an elastic connecting arm. The base body is provided with the insertion hole, the fixing ring is formed with the fixing hole, and the elastic connecting arm is connected to the base body and the fixing ring.

[0010] In an optional embodiment, the mounting base further includes an elastic flow guide shield connected to the side of the base body away from the tube body and surrounding the periphery of the insertion hole.

[0011] In an alternative embodiment, the fixing ring, the seat, and the elastic connecting arm are integrally formed.

[0012] In an optional embodiment, the outer casing has at least one storage slot, and the tube can be stored in the storage slot.

[0013] In an optional embodiment, the outer casing includes a left casing and a right casing. The left casing is detachably connected to the right casing and together with the right casing forms a mounting cavity, a clearance hole, and the slot. The assisting pressure rod is rotatably connected to the mounting cavity, and the force-applying end extends out from the clearance hole.

[0014] This utility model also proposes a spray painting device, including a spray paint bottle and a spray paint bottle assist mechanism. The spray paint bottle assist mechanism is the spray paint bottle assist mechanism as described above. The spray paint bottle includes a bottle body and a nozzle connected to each other. The nozzle is provided with a first spray port. The paint bottle assist mechanism includes a housing, an assist lever, and a spray pipe. The housing is provided with a slot, and the bottle body can be snapped into the slot. The assisting rod is rotatably connected to the housing, and the assisting rod has a force-applying end and a pressing end that are arranged opposite to each other. The pressing end can abut against the surface of the nozzle.

[0015] The paint bottle assist mechanism of this utility model is applied to a paint bottle, which includes a bottle body and a nozzle connected together. The nozzle is provided with a first spray nozzle. The paint bottle assist mechanism includes a housing, an assisting rod, and a spray pipe.

When a mist spraying is required, the user can directly press the original nozzle using the assist lever without installing the spray nozzle, making the painting operation more labor-saving. When the user needs to achieve precise straight-line, fine-line, or other spraying effects, different spray nozzles can be quickly installed. After installation, the second nozzle of the spray nozzle connects to the first nozzle of the nozzle, forming a new outflow channel. This can constrain and guide the originally diffused mist paint flow into a concentrated straight-line paint flow or other shapes, thus further expanding the painting modes and meeting the needs of different scenarios to a greater extent.

[0022] Reference Figures 1 to 6 This utility model proposes a paint spray bottle assist mechanism 100.

[0023] In this embodiment of the utility model, the paint bottle assist mechanism 100 is applied to a paint bottle 200. The paint bottle 200 includes a bottle body 210 and a nozzle 220 connected together. The nozzle 220 is provided with a first spray port 220a. The paint bottle assist mechanism 100 includes: a housing 10 with a slot 10a, into which the bottle body 210 can be engaged; an assisting pressure rod 20 rotatably connected to the housing 10, the assisting pressure rod 20 having a force-applying end 21 and a pressing end 22 disposed opposite to each other, the pressing end 22 abutting against the surface of the nozzle 220; and a spray pipe 30 detachably connected to the pressing end 22, the spray pipe 30 having a second spray port 30a communicating with the first spray port 220a.

[0024] The paint spray bottle assist mechanism 100 of this invention is applied to a paint spray bottle 200, which includes a bottle body 210 and a nozzle 220 connected to each other. Specifically, the bottle body 210 is made of metal and is filled with a mixture of paint and liquid propellant. The propellant vaporizes at room temperature, forming a stable high-pressure environment inside the sealed bottle body 210. The nozzle 220 is connected to the top of the bottle body 210 and forms a first nozzle 220a. The first nozzle 220a communicates with the inside of the bottle body 210 through a connecting pipe. A mechanical valve (not shown) is provided in the first nozzle 220a. When the user presses the nozzle 220, the mechanical valve of the first nozzle 220a is opened, and the high pressure inside the bottle body 210 forces the paint mixture to flow upward through the connecting pipe and be sprayed out at high speed from the first nozzle 220a. The sprayed paint forms a uniform fan-shaped paint curtain, achieving large-area spraying. After releasing the spray nozzle 220, the mechanical valve resets, and spraying stops. The structure and working principle of the paint can 200 are existing technologies and will not be elaborated upon here.

[0025] The paint spray bottle assist mechanism 100 includes a housing 10, an assisting lever 20, and a spray nozzle 30. The housing 10 comprises a left shell and a right shell made of plastic or metal. The left shell is detachably connected to the right shell by screws. The left and right shells together form a mounting cavity 10c, a clearance hole 10d, and a slot 10a. A mounting shaft is formed within the mounting cavity 10c. The assisting lever 20 can also be made of metal or plastic, and has a shaft hole formed by mechanical or molding methods. The mounting shaft passes through the shaft hole, rotatably connecting the assisting lever 20 and the housing 10. The two ends of the assisting lever 20 are a force-applying end 21 and a pressing end 22, respectively. The force-applying end 21 extends from the clearance hole 10d, and the pressing end 22 is partially exposed through the slot 10a. The lever arm from the force-applying end 21 to the mounting shaft is greater than the lever arm from the pressing end 22 to the mounting shaft, meaning the assisting lever 20 and the housing 10 form a force-saving lever.

[0026] The slot 10a is U-shaped with a rib at the bottom. When the bottle 210 is inserted into the slot 10a, the rib engages with the annular groove of the bottle 210, vertically limiting the position of the outer shell 10 and the bottle 210. This structure is existing technology and will not be described in detail here. After the bottle 210 is inserted into the slot 10a, its nozzle 220 is placed inside the slot 10a and below the pressing end 22. When the user presses the force application end 21, the assist lever 20 rotates relative to the outer shell 10 around the mounting shaft, and the pressing end 22 abuts against the surface of the nozzle 220, thereby causing the paint in the paint bottle 200 to be sprayed out through the first nozzle 220a.

[0027] This application allows for the detachable connection of an independent spray nozzle 30 to the pressing end 22 of the assistive pressure lever 20. When the user requires mist spraying, the nozzle 30 can be removed, and the user can directly use the assistive pressure lever 20 to press the original nozzle 220 for operation, making the painting operation more labor-saving. When the user needs to achieve precise spraying of straight lines, fine lines, or other spraying effects, different spray nozzles 30 can be quickly installed. After installation, the second nozzle 30a of the nozzle 30 is connected to the first nozzle 220a of the nozzle 220, forming a new outflow channel. This can constrain and guide the originally diffused mist paint flow into a concentrated straight paint flow or other shapes of paint flow. In this way, the painting modes are further expanded, which can meet the needs of different scenarios to a greater extent.

[0028] Please see again Figure 4 and Figure 5The nozzle 30 includes a tube body 31 and a fixing seat 32. The fixing seat 32 includes a fixing ring 321 integrally formed from metal or plastic material, a seat body 322, and an elastic connecting arm 323. The fixing ring 321 has a fixing hole 321a, and the seat body 322 has an insertion hole 322a, the position of which corresponds to the first nozzle 220a. The elastic connecting arm 323 connects the seat body 322 and the fixing ring 321. The pressing end 22 protrudes to form a fixing post 221, which can be fitted into the fixing hole 321a of the fixing ring 321, connecting the seat body 322 and the pressing end 22. The tube body 31 is inserted into the insertion hole 322a, connecting the second nozzle 30a to the first nozzle 220a. The structure and installation method of the nozzle 30 of this application are relatively simple, making it convenient for users to disassemble and assemble. Meanwhile, the fixed base 32 is connected to the fixed post 221 of the pressing end 22, ensuring that the positions of the insertion hole 322a and the first nozzle 220a always correspond, thereby ensuring the communication between the first nozzle 220a and the second nozzle 30a. It should also be noted that there is a certain gap between the base 322 and the nozzle 220, and the elastic connecting arm 323 has a certain elastic deformation. This prevents interference between the base 322 and the nozzle 220 or breakage of the elastic connecting arm 323 when pressed downwards, thus ensuring the effectiveness of the nozzle 30.

[0029] Please refer to the above. Figure 6 Furthermore, the sidewall of the fixing hole 321a is provided with multiple spaced positioning ribs 3211. In this application, there are four positioning ribs 3211, evenly spaced, and the cross-section of each positioning rib 3211 is semi-circular. The surface of the fixing post 221 is provided with multiple positioning grooves 221a, which also have semi-circular cross-sections. The positioning ribs 3211 can be embedded in the positioning grooves 221a to prevent relative rotation between the fixing seat 32 and the fixing post 221, which would affect the alignment of the first nozzle 220a and the second nozzle 30a. When it is necessary to switch to a mist spraying mode, the tube body 31 can be removed from the fixing seat 32, and the fixing seat 32 can be rotated 90° so that the positioning ribs 3211 are re-embedded in the positioning grooves 221a, and the seat body 322 is offset from the first nozzle 220a, exposing the first nozzle 220a.

[0030] Please see again Figure 4 In this application, the mounting base 32 also includes an elastic guide shield 324, which is made of silicone or rubber. The elastic guide shield 324 is connected to the side of the base 322 away from the tube body 31 and is arranged around the periphery of the insertion hole 322a. The elastic guide shield 324 can concentrate and guide the mist-like paint to one side of the tube body 31, thereby making the paint trajectory sprayed from the second nozzle 30a more concentrated and achieving better results.

[0031] Please see again Figure 5 In this application, the outer casing 10 is provided with a storage slot 10b, which can store the disassembled tube 31 for easy access by the user.

[0032] This utility model also proposes a spray painting device 1, which includes a paint bottle 200 and a paint bottle assist mechanism 100. The specific structure of the paint bottle assist mechanism 100 is as described in the above embodiments. Since this spray painting device 1 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The painting device 1 includes a paint bottle 200 and a paint bottle assist mechanism 100. The paint bottle assist mechanism 100 is as described above. The paint bottle 200 includes a bottle body 210 and a nozzle 220 connected together. The nozzle 220 is provided with a first nozzle 220a. The paint bottle assist mechanism 100 includes a housing 10, an assisting lever 20, and a spray pipe 30. The housing 10 is provided with a slot 10a, into which the bottle body 210 can be engaged. The assisting lever 20 is rotatably connected to the housing 10. The assisting lever 20 has a force-applying end 21 and a pressing end 22 arranged opposite to each other. The pressing end 22 can abut against the surface of the nozzle 220. The spray pipe 30 is detachably connected to the pressing end 22. The spray pipe 30 is provided with a second nozzle 30a that communicates with the first nozzle 220a.
