The air condenser is provided with a bracket for installation and fixation. The air condenser gradually converges from the bottom to the top. The bottom of the air condenser is open to form an air inlet. The top of the air condenser is provided with an air outlet. The exhaust device is installed on the air condenser and corresponds to the air outlet. The filter is arranged at the air inlet and covers the air inlet. The air condenser is provided with a mounting structure for installing the filter at the air inlet.

[0004] In the above technical solution, the filter can be disassembled by means of a mounting structure provided on the wind collecting hood so that the filter can be reused. The mounting structure mainly comprises two relatively arranged L-shaped supporting parts, and a slide groove adapted to the filter is formed between the L-shaped supporting part and the wind collecting hood. After the filter slides into the slide groove, the filter can be limited in the vertical direction, thereby achieving the fixation of the filter. However, the horizontal direction of the slide groove is still an open structure, and the filter is prone to horizontal deviation after sliding into the slide groove, resulting in a deviation between the filter and the air inlet, making it impossible to ensure that the particulate matter in the exhaust gas passing through the air inlet is fully intercepted. Summary of the Invention

[0021] like Figures 1 to 5 As shown, the utility model discloses an exhaust gas collection device for advertising cloth printing equipment, including a wind condenser 1, with brackets 9 for fixing on both sides of the wind condenser 1, the bottom to the top of the wind condenser 1 gradually converges, and an air outlet and an air inlet are formed at the top and bottom respectively, an exhaust mechanism 2 is provided on the top of the wind condenser 1, the exhaust mechanism 2 is opposite to the air outlet, a detachable filter 3 is provided at the air inlet, a supporting portion 4 is provided on the inner side of the wind condenser 1, and a slide 5 for the filter 3 to slide in or out is formed between the supporting portion 4 and the wind condenser 1, and the filter 3 is connected to the wind condenser 1. A locking mechanism 6 is provided between the wind collecting hood 1, and the locking mechanism 6 is used to fix the filter 3 to ensure the stability of the filter 3 during installation. After the filter 3 is installed at the air inlet, the filter 3 can be locked to avoid deviation between the filter 3 and the air inlet during use, and failure to ensure sufficient retention of particulate matter in the exhaust gas passing through the air inlet, thereby ensuring the stability of the filter 3 after installation. The specific structure of the exhaust mechanism 2 is the same as that in the prior art, that is, the exhaust mechanism 2 is composed of fan blades and a motor.

[0022] In this embodiment, the specific structure of the locking mechanism 6 includes a lock hook 61 fixed to the outer periphery of the filter 3, the lock hook 61 is located at one end away from the filter 3 and is in the form of a hook-shaped portion 611, the wind condenser 1 is provided with a through hole 7, the through hole 7 is opposite to the lock hook 61, the through hole 7 is used for the lock hook 61 to pass through the wind condenser 1, the outer side of the wind condenser 1 is provided with a protruding mounting seat 62, the mounting seat 62 is rotatably connected to the lock seat 63, the lock seat 63 is provided with a lock groove 631 adapted to the hook-shaped portion 611, the lock seat 63 is rotated to allow the hook-shaped portion 611 to pass through the wind condenser 1, and the lock seat 63 is provided with a lock groove 631 adapted to the hook-shaped portion 611. The lock hook 61 is inserted into the locking groove 631 to form a limited fit between the two. After the filter 3 slides into the sliding groove 5, the locking hook 61 can pass through the air collecting cover 1 from the through opening 7, so that the hook-shaped portion 611 of the locking hook 61 can cooperate with the locking seat 63. That is, after the locking hook 61 moves toward the locking seat 63, it can drive the locking seat 63 to rotate, so that the hook-shaped portion 611 can slide into the locking groove 631 of the locking seat 63 to form a limited fit between the two, thereby limiting the horizontal position of the filter 3, thereby ensuring the stability of the filter 3 after installation;

[0023] Among them, in order to prevent the lock seat 63 from malfunctioning and causing the hook portion 611 to fall out of the lock groove 631, a connecting seat 64 is further provided below the lock seat 63, and the connecting seat 64 is fixed to the mounting seat 62. A spring 65 is provided between the connecting seat 64 and the lock seat 63, and one end of the spring 65 is fixed to the lock seat 63, and the other end is fixed to the connecting seat 64.

[0024] When the locking hook 61 is moved toward the locking seat 63, the spring 65 compressed by the rotation of the lock seat 63 can drive the lock seat 63 to return to its original position and support the lock seat 63, so that a stable limit fit can be formed between the hook portion 611 and the lock slot 631.

[0025] In this embodiment, a pressure rod 8 extending outward is further provided on the side of the lock seat 63 away from the lock hook 61. The setting of the pressure rod 8 can facilitate manual driving of the lock seat 63 to rotate, that is, when the filter 3 needs to be removed, the pressure rod 8 is pressed to drive the lock seat 63 to rotate, so that the hook portion 611 can be disengaged from the lock groove 631. After the hook portion 611 is disengaged from the lock groove 631, the filter 3 can be pulled out of the slide groove 5 to realize the replacement of the filter 3, thereby improving the installation stability of the filter 3 without affecting the disassembly of the filter 3.

[0026] In this embodiment, a penetrating connecting waist hole 91 is further provided on the bracket 9. The bracket 9 is mainly installed by bolts and nuts. Through the setting of the connecting waist hole 91, the connection position of the bolts and nuts can be adjusted to a certain extent, thereby achieving a certain adjustment of the installation position of the bracket 9, so as to facilitate the installation of the wind collecting hood 1 through the bracket 9.

[0027] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
