Description

Technical Field

[0001] The present application relates to the technical field of airbrush, and more specifically, to a tail air intake anti-clogging airbrush. Background Art

[0002] An airbrush is a small painting tool that usually contains paint in a small can or container and sprays the paint onto the target surface through a fine nozzle. Airbrushes are usually used for fine painting work, such as automotive parts, electronic product housings, etc. Due to its small size and handheld nature, airbrushes can provide a high degree of control, ensuring that the paint is evenly and accurately sprayed onto the target surface.

[0003] When the existing airbrush is in use, dust and impurities in the air intake pipe will cause the atomizing nozzle to be blocked. The blocked nozzle will reduce the normal flow of paint, affect the atomization effect, make the spraying uneven, and thus reduce the efficiency and quality of painting. Utility Model Content

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0029] Reference Figure 1-Figure 5 , a tail air intake anti-clogging airbrush, comprising a shell 1, one side of the shell 1 is connected to a connecting rod 2, and one side of the connecting rod 2 is provided with an anti-clogging component;

[0030] The anti-clogging component comprises a filter screen 7, the outer side of the filter screen 7 is fixedly connected to a connecting tube 8, the outer side of the connecting tube 8 is fixedly connected to a plurality of blocks 12, and the plurality of blocks 12 are evenly distributed along the outer wall of the connecting tube 8.

[0031] By setting up the anti-clogging component, dust can be prevented from entering the interior of the airbrush housing 1 during air intake. The filter 7 can filter the gas entering from the air intake pipe 4, thereby reducing the accumulation of dust and impurities inside the airbrush, reducing the risk of clogging of the atomizing nozzle, extending the service life of the airbrush, and reducing the number of cleaning and maintenance times required due to clogging, thereby improving the spraying efficiency.

[0032] Reference Figure 1-Figure 2 A placement groove is provided at one end of the connecting rod 2, and the placement groove matches the connecting tube 8. A plurality of L-shaped grooves 11 are provided inside the placement groove, and the plurality of L-shaped grooves 11 are rotatably engaged with corresponding clamping blocks 12 respectively.

[0033] After using it for a period of time, if the flow rate of the spray pen nozzle decreases when spraying, the filter 7 may gradually become clogged, and dust and particles may accumulate on the surface. Separate the fixing rod 3 from the connecting rod 2, rotate the connecting tube 8 on the outside of the filter 7, so that the block 12 on one side of the connecting tube 8 is disengaged from the horizontal section of the L-shaped groove 11, and disengaged from the vertical section of the L-shaped groove 11, and the spring 10 rebounds. After disassembly, clean the filter 7. After cleaning, install the filter 7 into the placement groove of the connecting rod 2.

[0034] Reference Figure 3-Figure 4 A spring 10 is arranged inside the placement groove, and the spring 10 is located on one side of the connecting tube 8.

[0035] The spring 10 can exert force on the connecting tube 8, so that the block 12 is always located in the horizontal section of the L-shaped groove 11, avoiding separation of the block 12 from the horizontal section of the L-shaped groove 11, ensuring that the connecting tube 8 and the filter screen 7 remain stable in the placement groove, and effectively preventing impurities from leaking.

[0036] Reference Figure 1-Figure 5 A fixing rod 3 is provided at one end of the connecting rod 2, and the fixing rod 3 is plugged into the connecting rod 2. An air inlet pipe 4 is connected to one end of the fixing rod 3. A placement cavity 5 is connected to one end of the outer shell 1 away from the air inlet pipe 4. An adjustment key 6 is provided at one end of the outer shell 1 close to the placement cavity 5. A blocking block 9 is provided at the output end of the outer shell 1.

[0037] The placement cavity 5 is provided to place a container for storing paint;

[0038] By setting the adjustment key 6, the spray flow rate can be adjusted;

[0039] The air inlet pipe 4 is arranged at the tail of the airbrush, which can reduce the manufacturing process compared with the bottom air inlet in the prior art;

[0040] By setting the blocking block 9, the output end of the spray gun can be blocked when the spray pen is not in use, so as to prevent dust from entering the environment and causing clogging when the spray pen is in use.

[0041] Working principle: When in use, air is first taken in through the air inlet pipe 4, and then the container storing the paint is placed through the placement cavity 5, and the paint is atomized and sprayed out through the gas. When the air is taken in, the gas is filtered through the filter 7 to prevent dust and other impurities from entering the interior of the spray gun;

[0042] After using it for a period of time, if the flow rate of the nozzle of the airbrush decreases when spraying, the filter 7 may gradually become clogged, and dust and particles may accumulate on the surface. Separate the fixing rod 3 from the connecting rod 2, rotate the connecting tube 8 on the outside of the filter 7, so that the block 12 on one side of the connecting tube 8 disengages from the horizontal section of the L-shaped groove 11 and disengages from the vertical section of the L-shaped groove 11, and the spring 10 rebounds. After the disassembly is completed, clean the filter 7. After the cleaning is completed, install the filter 7 into the placement groove of the connecting rod 2, and then rotate the connecting tube 8. The block 12 on the outside of the connecting tube 8 is inserted into the horizontal section of the L-shaped groove 11. At this time, the spring 10 contracts, and the spring 10 will apply force to the connecting tube 8, so that the block 12 is always located in the horizontal section of the L-shaped groove 11, avoiding separation from the block 12 and the horizontal section of the L-shaped groove 11, so that the filter 7 is stably maintained in the placement groove, and then the fixing rod 3 is inserted into the connecting rod 2 for air intake.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
