[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0024] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0025] The first aspect of the utility model is as follows Figure 1 and Figure 2 As shown, the paint room 01 is just an existing conventional paint room 01, and the focus is on the exhaust assembly 02, which is installed on the top of the paint room 01 and is used to extract the exhaust gas generated by spraying paint.

[0026] Specifically, Figure 3 and Figure 5As shown, the exhaust assembly 02 is composed of an exhaust hood 101, a cable 107 and a power box 106. A filter 102 for filtering dust and paint mist in the exhaust gas is arranged inside the exhaust hood 101. The filter 102 is detachably connected to the exhaust hood 101, and can be connected by snap-on connection or bolt connection, etc., and it is necessary to ensure the stability after installation, as well as the convenience of installation and removal. The power box 106 is fixedly connected to the top of the paint room 01, and a cable reel 109 is arranged inside the power box 106. The upper end of the cable 107 is fixedly connected to the cable reel 109, and the cable 107 is wound on the cable reel 109, and the lower end of the cable 107 is fixedly connected to the exhaust hood 101. In addition, a lifting motor 108 is also provided in the power box 106 , and the lifting motor 108 is fixedly connected to the power box 106 . The cable reel 109 is rotationally connected to the power box 106 , and the cable reel 109 is also fixedly connected to the output shaft of the lifting motor 108 .

[0027] Therefore, after the exhaust assembly 02 is used for a long time, the exhaust hood 101 needs to be cleaned, or the internal filter 102 needs to be cleaned or replaced. The lifting and lowering is controlled by controlling the lifting motor 108. The lifting motor 108 rotates forward to make the cable reel 109 rotate forward, and the cable 107 starts to be released, and the exhaust hood 101 starts to descend. After the exhaust hood 101 descends to the ground, it is not only convenient but also safe to clean and replace it on the ground.

[0028] After the cleaning and replacement is completed, the lifting motor 108 is controlled to reverse so that the cable reel 109 is reversed and the cable 107 is wound up and the exhaust hood 101 starts to rise. When the exhaust hood 101 rises to the installation position, the whole operation is completed.

[0029] On the other hand, Figure 3 and Figure 4 As shown, the exhaust hood 101 is connected to an external exhaust pump through a branch pipe 104 and a main pipe 105, and the exhaust gas is filtered and then extracted to a subsequent treatment facility for subsequent treatment. There are a plurality of branch pipes 104, the lower ends of which are equidistantly arranged in the exhaust hood 101, and the upper ends of all branch pipes 104 are connected to the lower end of the main pipe 105, and the main pipe 105 and the branch pipes 104 are fixedly connected to the top of the paint room 01.

[0030] Specifically, the lower end of the branch pipe 104 is movably connected to the exhaust hood 101, and the lower end of the branch pipe 104 is fixedly connected to the upper connecting tube 103. The exhaust hood 101 is connected to the lower connecting tube 110 protruding upward, and the connecting tube 103 is sleeved on the lower connecting tube 110. The upper connecting tube 103 and the lower connecting tube 110 are slidably connected and can be combined or separated. The lower part of the upper connecting tube 103 is provided with an outward flaring for easy docking. Therefore, the descent and ascent of the exhaust hood 101 do not affect the branch pipe 104.

[0031] Preferably, a sealing ring 111 made of rubber is further provided in the upper connecting tube 103, the sealing ring 111 is located at the top of the lower connecting tube 110, and the diameter of the middle hole of the sealing ring 111 is smaller than the inner diameter of the lower connecting tube 110. The sealing ring 111 is provided to ensure the sealing performance, and the sealing ring 111 is made of thicker rubber. After the lower connecting tube 110 is combined with the upper connecting tube 103, the rubber will be squeezed by applying force, thereby blocking the gap and ensuring the sealing (it is not necessary to ensure complete sealing, even if there is a small amount of exhaust gas leakage, since the upper connecting tube 103 and the lower connecting tube 110 are still in the paint room 01, it will not leak into the external atmosphere, so it will not affect the use). Example

[0032] After the exhaust assembly 02 has been used for a long time, the worker needs to clean or replace the exhaust hood 101 and the filter 102 in the exhaust assembly 02, especially the filter 102. During operation, the worker only needs to control the lifting motor 108 to rotate forward through the remote control to make the cable reel 109 rotate forward, and the cable reel 109 rotates forward to release the wire, and the exhaust hood 101 starts to descend when the cable 107 is released. After the exhaust hood 101 descends to the ground, it is not only convenient but also safe to clean and replace it on the ground.

[0033] Since the lower end of the branch pipe 104 is movably connected to the exhaust hood 101, the upper connecting tube 103 and the lower connecting pipe 110 are slidably connected and can be connected or disconnected. Therefore, the exhaust hood 101 will be disconnected from the branch pipe 104 after it is lowered, so the external exhaust pump must be turned off before cleaning and replacing.

[0034] After the cleaning and replacement is completed, the lifting motor 108 is remotely controlled to reverse so that the cable reel 109 is reversed, and the cable reel 109 reverses and starts to reel in. The cable 107 is retracted and the exhaust hood 101 starts to rise. When the exhaust hood 101 rises to the installation position, the entire operation is completed. When the exhaust hood 101 rises to the installation position, it will dock with the branch pipe 104. The lower part of the upper connecting tube 103 at the lower end of the branch pipe 104 is provided with an outward flared opening, so the docking is convenient and stable.

[0035] After docking, the force generated by the combination of the lower connecting tube 110 and the upper connecting tube 103 will squeeze the rubber sealing ring 111, thereby blocking the gap and ensuring the sealing performance.

[0036] After the whole operation is completed, restart the vacuum pump, and the external vacuum pump creates negative pressure to extract air through the main pipe 105 and the branch pipe 104, and finally the negative pressure is transmitted to the vacuum hood 101, wherein the main pipe 105 is provided as one, and the branch pipes 104 are provided as a plurality of branches, which are arranged on the vacuum hood 101 at a distance, and the vacuum hood 101 is provided as a long strip, so it will bring a good vacuum effect. When the exhaust gas enters the vacuum hood 101, it will first pass through the filter 102 in the vacuum hood 101, and after being filtered once by the filter 102, it will finally be pumped to the subsequent treatment facilities for subsequent treatment.

[0037] Based on the above, the utility model sets an exhaust assembly 02 on the top of the paint room 01 to extract the exhaust gas generated by spraying paint, which does not occupy the operating space below. The exhaust assembly 02 includes multiple branch pipes 104 and a long exhaust hood 101, and a filter 102 is set in the exhaust hood 101 to improve the effect of extracting exhaust gas. The exhaust hood 101 and the filter 102 in the exhaust hood 101 can be controlled to rise and fall by controlling the lifting motor 108. When the exhaust hood 101, especially the filter 102, needs to be cleaned or replaced, it can be lowered, and then the operation on the ground is not only convenient but also safe.
