Description

Technical Field

[0001] This utility model relates to the field of ventilation structure technology, specifically to an automotive air conditioning ventilation structure. Background Technology

[0002] In the utility model application titled "A Guide Structure for Automotive Air Conditioning Vents" (publication number: CN218054797U, publication date: 2022-12-16), the following features: an installation pipe installed inside the air conditioning vent; a guide pipe screwed onto the inner wall of the installation pipe; the inner wall of the guide pipe connected to two guide plates via a rotating shaft; and the ends of the two guide plates connected via a linkage assembly. A filter unit perpendicular to the airflow direction is inserted into the inner wall of the guide pipe. This utility model utilizes a detachable filter unit, which not only filters and prevents dust from entering the inner cavity of the guide pipe but also facilitates the disassembly and assembly of the filter unit. Compared to a combined guide pipe and installation pipe structure, this improves the flexibility of disassembly and assembly, enabling quick disassembly and maintenance of the guide structure.

[0003] In the prior art, including the aforementioned patent, in order to accelerate the ventilation efficiency of air conditioning, an exhaust fan is usually installed in the vent. As the exhaust fan rotates, it generates static electricity through friction with the air, causing dust to adhere to the surface of the exhaust fan. Therefore, it is necessary to clean the dust on the exhaust fan blades every once in a while. This is usually done by brushing. However, the cleaning is affected by factors such as space, which makes it difficult to clean the dust on the surface of the fan blades thoroughly. Utility Model Content

[0004] The purpose of this invention is to provide an automotive air conditioning ventilation structure to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automotive air conditioning ventilation structure includes a bracket; it also includes a ventilation fan rotatably connected to the bracket, wherein the ventilation fan and the bracket are connected by a sleeve shaft, and the sleeve shaft and the ventilation fan are detachably connected by a locking assembly.

[0007] Preferably, the locking assembly includes a connector and a drive component, the drive component being used to lock and limit the ventilation fan by driving the connector.

[0008] Preferably, the connector includes a plurality of connector blocks slidably connected in the radial direction of the sleeve shaft, and each connector block is fixedly connected with a transmission pin.

[0009] Preferably, the driving component includes a rotating handle coaxially arranged with the sleeve shaft, and the rotating handle is provided with a plurality of waist-shaped grooves adapted to the transmission pins, with each waist-shaped groove corresponding to a transmission pin.

[0010] Preferably, a plug groove adapted to each plug block is provided on the periphery of the connecting shaft of the ventilation fan at the position corresponding to each plug block.

[0011] In the above technical solution, the present invention provides an automotive air conditioning ventilation structure that connects the sleeve shaft and the ventilation fan through a locking component, so that the ventilation fan and the sleeve shaft can be detachably connected, thereby making it convenient for users to remove the ventilation fan for cleaning, and making the dust attached to the ventilation fan more thoroughly removed.
