Description

Technical Field

[0001] This utility model relates to the field of spray gun technology, and in particular to a spray gun structure. Background Technology

[0002] Currently, lathes are machine tools primarily used to machine rotating workpieces using cutting tools. Drills, reamers, taps, dies, and knurling tools can also be used on lathes for various machining operations. Lathes are mainly used for machining shafts, discs, sleeves, and other workpieces with rotating surfaces. They are among the most widely used machine tools in machinery manufacturing and repair shops, and are widely applied in various machining fields. During machining, lathes often use air guns to clean the machine tool and prevent debris residue from affecting the machining process. Traditional air guns are directly connected to air compressors, resulting in the ejected gas containing moisture or dust. This moisture-laden gas not only increases the internal humidity of the lathe, causing internal parts to rust and thus damaging the lathe, but the dust carried by the high-speed gas can also scratch internal parts, affecting subsequent machining accuracy.

[0003] Existing jet guns use separate dust and water vapor filters on the pipes connected to the air compressor to filter out dust and water vapor from the gas before it is ejected from the jet gun, thus preventing the water vapor and dust in the gas from affecting the internal components of the lathe. However, its structural design is flawed. Since the dust and water vapor filters are set up separately and connected by pipes, they occupy a lot of space, which is not conducive to deployment in the compact lathe environment. At the same time, the filter elements need to be disassembled one by one when replacing or cleaning them, which is inconvenient to maintain, inefficient, and cannot meet the user's needs, thus limiting its applicability.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a spray gun structure that integrates a dust filter unit and a water vapor filter unit on the filter chamber, eliminating the need for separate dust and water vapor filters in the traditional method. This reduces the space required and facilitates the installation and use of the spray gun in confined spaces such as lathes, thereby reducing manufacturing costs and maintenance complexity, meeting user needs, and having a wide range of applications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A spray gun structure includes an air compressor, an air gun, and a filtering mechanism. The filtering mechanism includes a body and a dust filtering unit and a water vapor filtering unit disposed on the body. The body has a filter chamber with an air inlet and an air outlet. The dust filtering unit and the water vapor filtering unit are both disposed on the filter chamber. The air inlet is connected to the air compressor through a first pipe, and the air outlet is connected to the air gun through a second pipe.

[0008] As a preferred embodiment, both the dust filtration unit and the water vapor filtration unit can be detachably mounted on the machine body.

[0009] As a preferred embodiment, the dust filtration unit includes a first mounting frame and a dust filter element disposed on the first mounting frame. The first mounting frame is detachably mounted on the machine body, and the dust filter element is located on the filter chamber.

[0010] As a preferred embodiment, the water vapor filtration unit includes a second mounting bracket and a water vapor filter element disposed on the second mounting bracket. The second mounting bracket is detachably mounted on the body, and the water vapor filter element is located on the filtration chamber.

[0011] As a preferred embodiment, a water collection tank is provided on the filter chamber corresponding to the water vapor filtration unit. The water collection tank is used to collect the water filtered out by the water vapor filtration unit. A drain pipe connected to the water collection tank is provided on the outside of the machine body, and a drain valve is provided on the drain pipe.

[0012] As a preferred embodiment, a sealing element is provided between the water collection tank and the water vapor filtration unit.

[0013] As a preferred embodiment, two dust filtration units are provided, which are arranged at intervals on the filtration chamber and located between the air inlet and the air outlet. The water vapor filtration unit is located between the two dust filtration units.

[0014] As a preferred embodiment, one water vapor filtration unit is provided; or, two water vapor filtration units are provided and arranged sequentially from the air inlet end to the air outlet end.

[0015] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly uses a filter mechanism design to integrate dust filter unit and water vapor filter unit on the filter chamber. This allows the gas to enter the filter chamber for dust and moisture filtration before being sprayed out from the air gun. This eliminates the need for separate dust and water vapor filters in the traditional method, occupies less space, and is conducive to the installation and use of the spray gun in confined spaces such as lathes. It also reduces manufacturing costs and maintenance complexity, meets user needs, and has a wide range of applications.

[0016] Furthermore, the water collection tank facilitates the collection of water filtered out by the water vapor filtration unit. Combined with the drain pipe, it allows for the periodic discharge of water from the collection tank, ensuring excellent usability. At the same time, the sealing components prevent gas from entering the collection tank through the gap between the water vapor filtration unit and the collection tank, thus ensuring the stability of gas filtration.

Preferably, the first pipe 11 and the second pipe 21 are both flexible hoses, the dust filter element 322 is a sintered metal mesh or glass fiber, and the water vapor filter element 332 is a porous activated alumina. Thus, through the design of the filtration mechanism, the dust filter unit and the water vapor filter unit are integrated on the filter chamber to achieve gas entering the filter chamber for dust and moisture filtration before being sprayed out from the air gun. This eliminates the need for separate dust and water vapor filters in the traditional method, occupies less space, and is conducive to the installation and use of the spray gun in narrow spaces such as lathes. It reduces manufacturing costs and maintenance complexity, meets user needs, and has a wide range of applications.

[0027] Furthermore, the dust filter unit 32 is provided in two or more locations arranged at intervals between the air inlet end 311 and the air outlet end 312, and the water vapor filter unit 33 is located between the two dust filter units 32, and there is one water vapor filter unit 33; or, there are two water vapor filter units 33 arranged sequentially along the air inlet end 311 toward the air outlet end 312; preferably, there are two dust filter units 32 and one water vapor filter unit 33; in this way, the appropriate number of dust filter units and water vapor filter units can be configured according to the usage requirements, thereby meeting the user's jet application in different scenarios.

Additionally, the support column facilitates the support and installation of the water vapor filtration unit on the filter chamber, ensuring stable operation of the water vapor filtration unit.

[0029] The key design feature of this utility model is that it integrates dust filtration and water vapor filtration units into the filtration chamber through a filtration mechanism design. This allows the gas to enter the filtration chamber for dust and moisture filtration before being sprayed out from the air gun. This eliminates the need for separate dust and water vapor filtration in traditional designs, resulting in a smaller footprint. This design facilitates the installation and use of the entire spray gun in confined spaces such as lathes, reduces manufacturing costs and maintenance complexity, meets user needs, and has a wide range of applications.

[0030] Furthermore, the water collection tank facilitates the collection of water filtered out by the water vapor filtration unit.
