Detailed implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1: The existing automotive air-conditioning blower is inconvenient for convenient shock absorption and disassembly and installation, resulting in continuous vibration of the blower during vehicle driving and reducing its service life. To solve this technical problem, the following technical content is disclosed in this embodiment. Please refer to Figures 1-6 as shown; An automotive air-conditioning blower with shock-absorbing disassembly type includes a fixed seat 1 fixedly connected to the air-conditioning duct through bolts, and a mounting seat 6 is arranged on the fixed seat 1, and a motor 7 is fixedly installed on the mounting seat 6. At the same time, the output end of the motor 7 is fixedly connected to a fan blade assembly; A shock-absorbing seat 2 is elastically lifted and installed on the fixed seat 1, and an adjusting seat 11 is slidably sleeved outside the motor 7. At the same time, a connecting rod 12 is evenly rotatably connected to the outside of the adjusting seat 11. The upper end of the connecting rod 12 is rotatably connected to a positioning pin 13, and the positioning pin 13 penetrates through the mounting seat 6 and is inserted into the shock-absorbing seat 2; The shock-absorbing seat 2 is arranged in a ring structure, and guide posts 3 are evenly fixedly connected to the lower surface of the shock-absorbing seat 2. A guide cylinder 5 is fixedly connected to the lower end of the fixed seat 1. At the same time, the guide posts 3 penetrate through the lower end of the fixed seat 1 and the guide cylinder 5, and a piston piece 4 is fixedly connected to the outer side of the lower part of the guide posts 3. The piston piece 4 is located on the inner wall of the guide cylinder 5, and the piston piece 4 and the guide cylinder 5 are in interference sliding connection. The fixed seat 1 and the shock-absorbing seat 2 are elastically connected by a spring.

[0022] The fan blade assembly includes a lower blade seat 8 fixedly installed at the output end of the motor 7, and an upper blade seat 10 is arranged in parallel above the lower blade seat 8. At the same time, fan blades 9 are evenly fixedly connected between the lower blade seat 8 and the upper blade seat 10.

[0023] The adjusting seat 11 is annularly structured and is sleeved on the outside of the motor 7 in a lifting manner. During the lifting process of the adjusting seat 11, the positioning pin 13 is driven by the connecting rod 12 to perform telescopic adjustment at the lower part of the mounting seat 6. A spring is fixedly connected between the positioning pin 13 and the mounting seat 6. At the same time, the positioning pin 13 is moved by the elastic force of the spring and is clamped outside the shock-absorbing seat 2.

[0024] By adopting the above technical solution, when the blower needs to be installed, the adjusting seat 11 outside the motor 7 is pulled downwards, so that the adjusting seat 11 drives the positioning pin 13 to move elastically through the connecting rod 12. Then, the fixing seat 1 and the shock-absorbing seat 2 are sleeved on the outside of the mounting seat 6. When the positioning pin 13 moves to the corresponding positioning hole position of the shock-absorbing seat 2, the adjusting seat 11 is released. At this time, the positioning pin 13 will automatically snap into the positioning hole on the shock-absorbing seat 2 under the action of the elastic force of the spring, realizing the installation of the shock-absorbing seat 2 and the mounting seat 6. Then, the fixing seat 1 is fixedly connected to the air duct housing through bolts, thus realizing the quick shock absorption installation of the blower. Subsequently, by pulling down the adjusting seat 11, the assembly of the shock-absorbing seat 2 and the mounting seat 6 can be released, facilitating the subsequent maintenance of the blower. When the air duct housing shakes due to bumps during the subsequent vehicle driving, the shock-absorbing seat 2 will cause the guide post 3 to drive the piston piece 4 to slide inside the guide cylinder 5, realizing effective shock absorption, avoiding the shock-absorbing seat 2 and the blower from shaking with the air duct housing, and thus extending the service life of the blower.

[0025] Embodiment 2: The technical content disclosed in this embodiment is a further improvement based on the above Embodiment 1. The existing automotive air-conditioning blower is inconvenient to automatically clean the blades during use. In order to further solve this technical problem, the following technical content is disclosed in this embodiment, as Figures 3-9 shown; a cleaning component driven by centrifugal force is arranged on the fan blade assembly. The inside of the mounting seat 6 is elastically connected with a pressing plate 18 through a spring. The outside of the pressing plate 18 is fixedly installed with an adapter column 19. A gas transmission bag 20 is fixedly connected between the pressing plate 18 and the mounting seat 6. At the same time, an air inlet pipe and an exhaust pipe are connected to the outside of the gas transmission bag 20. A collection bin 21 for collecting dust and impurities is also installed at the upper end of the mounting seat 6.

[0026] The cleaning component includes centrifugal rods 14 evenly and rotatably installed on the outside of the upper blade seat 10, and the centrifugal rods 14 rotate by the action of centrifugal force when the upper blade seat 10 rotates.

[0027] The cleaning component further includes a scraping plate 17 sleeved on the outside of the fan blade 9. The scraping plates 17 are fixedly connected to each other through a support frame 15. A pull rope 16 is fixedly connected between the centrifugal rod 14 and the support frame 15. When the centrifugal rod 14 rotates centrifugally, the support frame 15 is pulled by the pull rope 16 to perform lifting adjustment. During the lifting process of the support frame 15, the outside of the fan blade 9 is cleaned by the scraping plate 17.

[0028] On the outer side of the pressing plate 18, a connecting column 19 is fixedly installed, and the connecting column 19 is telescopically installed on the mounting seat 6. One end of the connecting column 19 close to the fixed seat 1 is arranged in an inclined plane. At the same time, the inclined plane arranged at the end of the connecting column 19 fits against the hole wall of the air-conditioning air duct. Moreover, during the shock-absorbing lifting and adjusting process of the mounting seat 6, the connecting column 19 drives the pressing plate 18 to perform elastic movement adjustment.

[0029] One-way valve structures are arranged on both the air inlet pipe and the exhaust pipe connected to the air delivery balloon 20. The air inlet pipe is connected to the collection bin 21. During the compression and stretching processes of the air delivery balloon 20, air is inhaled through the air inlet pipe and discharged through the exhaust pipe.

[0030] The collection bin 21 is arranged in an annular structure. Collection holes 22 are formed in the inner wall of the collection bin 21, and the collection holes 22 face the lower part of the fan blade assembly. A baffle 23 is elastically lifted and installed on the collection bin 21, and the baffle 23 covers the collection holes 22. At the same time, a magnetic sheet 24 is fixedly installed on the outer side of the lower part of the support frame 15. The baffle 23 is made of a magnetic material, and the magnetic poles of the opposite faces of the baffle 23 and the magnetic sheet 24 are opposite. When the support frame 15 drives the magnetic sheet 24 to move downward, the baffle 23 is elastically lifted and adjusted by magnetic force.

[0031] By adopting the above technical solutions, when the motor 7 drives the lower blade seat 8, the fan blade 9, and the upper blade seat 10 to rotate, air can be delivered. At the same time, when the upper blade seat 10 rotates at a high speed, the centrifugal rod 14 thereon will rotate under the action of centrifugal force. At this time, the centrifugal rod 14 will pull the support frame 15 to move upward through the pull rope 16. At this time, the scraper 17 installed on the support frame 15 can move upward synchronously with the fan blade 9. At the same time, the shock-absorbing seat 2 and the mounting seat 6 will perform shock-absorbing movements. At this time, the air duct shell will reciprocally squeeze the inclined plane of the connecting column 19, so that the connecting column 19 pushes the pressing plate 18 to perform elastic reciprocating movement. At this time, the pressing plate 18 can reciprocally squeeze and stretch the air delivery balloon 20, so that the air delivery balloon 20 extracts the air inside the collection bin 21 through the air inlet pipe (at this time, the baffle 23 blocks the collection holes 22) and discharges it through the exhaust pipe, so that a certain negative pressure state is maintained inside the collection bin 21. When the blower stops working, the centrifugal force received by the centrifugal rod 14 decreases, so that the centrifugal rod 14 rotates and resets. At this time, the support frame 15 will drive the scraper 17 to move downward synchronously to realize automatic cleaning of the fan blade 9. When the support frame 15 moves downward, the magnetic sheet 24 on its outer side will gradually approach the baffle 23, so that the baffle 23 moves upward under the action of magnetic force, so that the collection holes 22 are opened. At this time, the collection bin 21 can suck up the swept impurities, dust, etc. to realize centralized collection, which is convenient for subsequent processing and cleaning.

[0032] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
