Description

Technical Field

[0001] This utility model relates to the field of air filter technology, specifically to a quick-connect device for the air outlet of a fresh air filter. Background Technology

[0002] A fresh air filter is a device that uses porous filter materials to capture dust from a gas-solid two-phase flow and purify the gas. It typically has multiple air vents. Currently, the connection between an external air duct and these vents usually involves using a guide sleeve, rubber rings, and clamps. The guide sleeve is installed on the fresh air filter, with the vents corresponding to the external air ducts. Then, the rubber ring is placed on the guide sleeve, followed by the external air duct, which is then fitted onto the guide sleeve and rubber ring. Finally, clamps are used to secure the external air duct to the guide sleeve, thus connecting it to the filter. However, because there are multiple vents, this connection method is time-consuming and labor-intensive, reducing the efficiency of installing external air ducts and providing a poor user experience.

[0026] Please see Figures 1-6This application provides a technical solution: a quick-connect device for the air outlet of a fresh air filter, including a fresh air filter body 110, an air guide sleeve 140, a screw 160, an air guide tube 170, a sealing ring 190, and a locking mechanism 192. The fresh air filter body 110 has air holes 120. The air guide sleeve 140 is fixed to the upper surface of the fresh air filter body 110 by the screw 160. A threaded groove 130 is formed on the shell of the fresh air filter body 110, and the lower end of the screw 160 is threaded into the threaded groove 130. The air guide sleeve 140 and the air holes 120 are correspondingly arranged. It also includes a sealing gasket 150, which is disposed between the upper surface of the fresh air filter body 110 and the lower surface of the air guide sleeve 140. The sealing ring 190 is sleeved on the air guide tube 170, and the air guide tube 170 is inserted into the air guide sleeve 140. Within 40, several air guide sleeves 140 are provided, and these air guide sleeves 140 are linearly and equidistantly arranged on the fresh air filter body 110. The air guide sleeves 140 and the air holes 120 correspond one-to-one. Each air hole 120 is surrounded by multiple threaded grooves 130. The multiple threaded grooves 130 make the air guide sleeve 140 more firmly fixed on the fresh air filter body 110. It also includes a slider 180, which is fixed on the outer wall of the air guide tube 170. The air guide sleeve 140 is provided with a sliding groove 194, and the slider 180 is slidably inserted into the sliding groove 194. The arrangement of the slider 180 and the sliding groove 194 allows the end of the U-shaped rod 1923 to be quickly positioned together with the positioning groove 191. The air guide sleeve 140 is provided with a limiting groove 193, and the sealing ring 190 is inserted into the limiting groove 193. The setting of the limiting groove 193 realizes the limiting of the sealing ring 190.

[0027] The locking mechanism 192 is installed on the air guide sleeve 140 and the air guide pipe 170. The locking mechanism 192 enables the air guide pipe 170 to be quickly installed onto the air guide sleeve 140. The locking mechanism 192 includes a spring 1922 and a U-shaped rod 1923. The air guide sleeve 140 has a countersunk hole 1921. One end of the spring 1922 is fixed in the countersunk hole 1921. The U-shaped rod 1923 slides through the countersunk hole 1921. The other end of the spring 1922 is fixed on the outer wall of the U-shaped rod 1923. One end of the U-shaped rod 1923 is inserted into the air guide pipe 170. The air guide pipe 170 has a positioning groove 191. One end of the U-shaped rod 1923 is inserted into the positioning groove 191. The U-shaped rod 1923 has an inclined surface 1924.

[0028] The working principle and process of this utility model are as follows: In use, the sealing gasket 150 is placed under the air guide sleeve 140, and the air guide sleeve 140 is installed on the fresh air filter body 110 using screws 160, so that the air guide sleeve 140 and the air hole 120 correspond. Then, the sealing ring 190 is fitted onto the air guide tube 170. Then, the slider 180 and the slide groove 194 are aligned. Then, the air guide tube 170 is pressed down. The air guide tube 170 is pressed through the inclined surface 1924, so that one end of the U-shaped rod 1923 enters the countersunk hole 1921 until the air guide tube 170 is lowered to the designated position, the sealing ring 190 enters the limiting groove 193, and the spring... The reaction force of 1922 causes one end of the U-shaped rod 1923 to be inserted into the positioning groove 191, realizing the quick connection of the air duct 170 and the air guide sleeve 140. When the air duct 170 needs to be removed, both U-shaped rods 1923 are pushed at the same time, so that one end of the U-shaped rod 1923 enters the countersunk hole 1921. Then, the air duct 170 is pulled up to separate the air duct 170 and the air guide sleeve 140. This quick connection device for the air outlet of the fresh air filter can realize the quick assembly and disassembly of the air duct 170 and the air guide sleeve 140 by using the locking mechanism 192, saving time and effort, improving the installation efficiency of the air duct 170, and bringing a better user experience.

[0029] The embodiments of this utility model have been described in detail above, but the content is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
