Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories, in particular to an air suction fan used in a seat ventilation system. Background Art

[0002] The pursuit of comfort in car seats is worthy of attention. The ventilation system of car seats can effectively improve the air circulation environment of the contact part between the human body and the seat. Even if you sit for a long time, the contact surface between the body and the seat will be dry and comfortable, providing a comfortable riding environment for the driver and passengers. In the current seat design, most of the seats on the market are blowing structures. The blowing structure uses a fan to blow air directly at the human body, which is easy to cause adverse effects on human health, especially for seats with air conditioning. The cold air blows directly on the human buttocks and waist, which is easy to cause back pain and other problems. Therefore, some seats with exhaust structures have appeared on the market, and their fans directly blow air at the human body.

[0028] See also Figure 1-8 , the present invention provides a technical solution:

[0029] like Figure 1-2 As shown, the suction fan for the seat ventilation system includes a suction module 100, a silencer module 200, an air inlet module 300 and an air outlet module 400. The suction module 100 is arranged inside the silencer module 200, the air outlet of the silencer module 200 is connected to the air outlet module 400, the air inlet of the suction module 100 is connected to the air inlet module 300, the air inlet module 300 includes an air bag and an air duct, the ends of the air duct are respectively connected to the air inlet of the suction module 100 and the air outlet side of the air bag, when the suction module 100 is working, negative pressure is formed at the air outlet of the air inlet module 300, at this time, the hot air emitted from the user enters the suction module 100 through the air bag and the air duct, the suction module 100 then discharges the hot air through the air outlet module 400, the noise generated when the suction module 100 is working is greatly reduced under the action of the silencer module 200, thereby improving the user's comfort.

[0030] like Figure 3-4As shown, the air suction module 100 includes a shell, the air inlet side of the shell is a convex structure, a plurality of air outlets 104 are arranged on the shell in a surrounding manner, a connecting disk 106 is arranged on the air inlet side of the shell, a plurality of blocks 107 are arranged on the connecting disk 106, and a plurality of connecting strips 105 corresponding to the blocks 107 are arranged on the air inlet side of the shell. The connecting strips 105 can be moved to one side of the connecting disk 106 by rotating the shell, so as to realize the quick connection between the air suction module 100 and the air inlet module 300. The convenient and quick installation can also facilitate the subsequent maintenance or replacement of the air suction module 100. An impeller 109 is connected to the shell through a drive shaft 108, a motor for driving the drive shaft 108 is arranged in the shell, one end of the drive shaft 108 in the shell extends out of the shell and is connected to a fan blade 110, and the fan The blades 110 are arranged between the shell and the rear side wall of the silencer 201. By controlling the operation of the motor, the driving shaft 108 can synchronously drive the fan blades 110 to rotate, so that the air in the space surrounded by the silencer 201 and the silencer disk 204 moves. An air inlet module 300 is arranged on the connecting disk 106, and the air suction module 100 is arranged inside the silencer module 200. An air outlet module 400 is arranged at the air outlet of the silencer module 200. In this embodiment, the number of air outlets 104 is six, which can minimize the resistance during exhaust, increase the air volume, reduce the wind noise generated when the fan runs at high speed, and reduce or avoid the generation of vortexes that cause the fan efficiency to decrease. The air outlet 104 is a worm gear structure, which can increase the suction force of the fan, make the airflow larger and dissipate heat faster.

[0031] The shell includes a lower shell 101 and an upper shell 102, and the lower shell 101 and the upper shell 102 are fixedly connected by screws. The abutting sides of the lower shell 101 and the upper shell 102 are provided with a stopper 103 for positioning the upper shell 102. The stopper 103 facilitates the staff to install the lower shell 101 and the upper shell 102, and a plurality of fixing blocks are provided on the rear side of the lower shell 101.

[0032] like Figure 5-6As shown, the silencer module 200 includes a silencer cover 201, and a plurality of screws 202 on the silencer cover 201 are respectively connected with a plurality of fixing blocks on the shell. The silencer cover 201 is connected with a silencer plate 204 through the screws 202. The silencer plate 204 is provided with a through hole corresponding to the air inlet side of the shell. The screws 202 are provided with a rubber ring 203. The silencer cover 201 is provided with a plurality of exhaust parts corresponding to the plurality of air outlets 104. During installation, the staff first sets the silencer plate 204 on the connecting plate 106, and then After the suction module 100 is installed, the silencer 201 is put on the outside of the suction module 100, and the threaded end of the screw 202 passes through the silencer 201 and the fixing blocks on the shell in turn and is threadedly connected with the silencer plate 204 to complete the fixing work. At the same time, the air outlet 104 is aligned with the air inlet of the exhaust part. After the installation is completed, the silencer 201 and the silencer plate 204 can effectively reduce the noise of the suction module 100, and the setting of the rubber ring 203 can effectively buffer the suction module 100 in operation.

[0033] like Figure 8 As shown, the exhaust member includes a connecting pipe 205, the air inlet side of the connecting pipe 205 is against the air outlet 104, and a silencer pipe 206 is arranged on the air outlet side of the connecting pipe 205, and the end of the silencer pipe 206 extends out of the silencer cover 201, and a plurality of blocking plates 207 are arranged in the silencer pipe 206, and the cross section of the blocking plate 207 is a V-shaped structure, and the blocking plate 207 is provided with a through hole 208, and the central axis of the plurality of through holes 208 coincides with each other. When in use, the wind exhausted by the suction module 100 can enter the silencer pipe 206 through the connecting pipe 205. When the wind passes through the through holes 208 on the plurality of blocking plates 207 in turn, a part of the wind collides with the inclined surface of the blocking plate 207 under the action of the blocking plate 207, and at the same time, the noise generated by the air passing through the blocking plate 207 and part of the noise generated when the suction module 100 is working are gradually reduced through the reflection of the blocking plate 207 and the inner wall of the silencer pipe 206, thereby further improving the noise reduction effect.

[0034] A heat conducting member is provided on the silencer 201, and a connecting piece 213 is provided on the inner circumference of the heat conducting member. A protective cover 215 is provided on the rear side of the silencer 201, and an adjusting screw 214 is provided on the protective cover 215, and the adjusting screw 214 is threadedly connected to the connecting piece 213. When in use, the user can rotate the adjusting screw 214 as needed, and the connecting piece 213 can drive the heat conducting member to start moving under the action of the thread, so that the heat conducting member can be used to exchange heat with the outside world through the heat conducting member as needed. For example, in summer, the cold air from the outside world cools down the space enclosed by the silencer 201 and the silencer disk 204 through the heat conducting member, so that the hot air in the silencer pipe 206 can be cooled down, so that the temperature of the hot air absorbed by the air outlet module 400 is reduced and then blown toward the user's body through the air outlet module 400, thereby improving the user's comfort.

[0035] like Figure 7 As shown, the heat conducting member includes a mounting plate 209, on which a plurality of heat conducting fins 210 are arranged, one end of the plurality of heat conducting fins 210 extends to the interior of the muffler cover 201 and is connected to a plurality of reinforcing ribs 211, and a sealing ring 212 is arranged on the side of the mounting plate 209 opposite to the muffler cover 201. In this embodiment, the plurality of heat conducting fins 210 are divided into six groups, and the number of reinforcing ribs 211 is six, so as to improve the uniformity of heat conduction to the space enclosed by the muffler cover 201 and the muffler plate 204, and the muffler cover When heat is exchanged in the space enclosed by the silencer cover 201 and the silencer disk 204, the heat exchange efficiency of the enclosed space can be changed by controlling the length of the heat-conducting fins 210 extending out of the silencer cover 201. The reinforcing ribs 211 can increase the connection strength between the heat-conducting fins 210 while also increasing the heat-conducting area. By controlling the operation of the motor, the drive shaft 108 can synchronously drive the fan blades 110 to rotate, so that the air in the space enclosed by the silencer cover 201 and the silencer disk 204 moves, thereby making the temperature of the enclosed space uniform.

[0036] like Figure 2 As shown, the air outlet module 400 includes an annular channel 401, which is arranged on the outer peripheral surface of the silencer 201, and the air outlet ends of the multiple silencer pipes 206 are all located inside the annular channel 401. A mounting shell 402 is arranged on the top of the annular channel 401, and the top of the mounting shell 402 is connected to multiple air outlet bags 404 through multiple air outlet pipes 403. An adsorption unit 405 is plugged into one side of the mounting shell 402, wherein the adsorption unit 405 is plugged into the mounting shell 402 and fixed with bolts, and the adsorption unit 405 is sequentially composed of a magma red stone adsorption layer, an activated carbon adsorption layer and a silver ion sterilization layer along the air circulation direction.

[0037] The working process of this embodiment is as follows: after the staff completes the installation of the suction module 100, the silencer module 200, the air inlet module 300 and the air outlet module 400, a negative pressure is formed at the air outlet of the air inlet module 300 by controlling the operation of the suction module 100. At this time, the hot air emitted from the user enters the suction module 100 through the wind bag and the air duct, and the suction module 100 discharges the hot air through the air outlet module 400. During the process of the hot air circulating inside the silencer 206, the hot air enters the annular channel 401 after heat exchange, and then passes through the adsorption and sterilization process of the adsorption unit 405 and is blown to the surface of the human body through the air outlet bag 404, thereby improving the user's comfort.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
