Abstract
Description
Technical Field
[0001] The utility model relates to a front air net installation structure of a desktop fan.
Background Art
[0002] In our daily life, the electric fan is an essential living tool for us. Every hot summer, we use the electric fan to bring us some coolness. The existing desktop fans generally use direct current brushless motors, which belong to the external rotor structure. The motor shaft is embedded in the middle of the wind blade, and the motor shaft is generally directly locked on the bearing of the stator through a circlip. During use, more and more dust will accumulate on the wind blade, and a large number of bacteria in the air will also adhere to the wind blade. If not cleaned for a long time, it will seriously affect the performance of the fan and endanger human health. For the existing desktop fans, their front air nets are generally integrated with the fan housing. When disassembling, a large number of screws need to be disassembled, and the internal electronic components and wires will be exposed, which causes inconvenience to the user's assembly and is not convenient for the user to clean the wind blade after disassembly.
[0003] Therefore, it is necessary to make further improvements to it.
Content of the Utility Model
[0004] To achieve the above object, the utility model provides a front air net installation structure of a desktop fan, which includes a rear net cover and a front air net. An installation surface is provided on the front side of the rear net cover, and a plurality of bayonets are distributed on the installation surface. Hooks corresponding to the bayonets are provided at the positions of the front air net, and the hooks are matched with the bayonets to install the front air net on the rear net cover.
[0005] In one or more embodiments, a part of the plurality of bayonets is provided on the left and right sides of the installation surface, and at least one of the plurality of bayonets is provided on the upper part of the installation surface, and the hooks are arranged upward.
[0006] In one or more embodiments, the front air net is connected and fixed to the rear net cover by screws. Screw holes are provided on the installation surface, and installation holes corresponding to the screw holes are provided at the positions of the front air net.
[0007] In one or more embodiments, the rear net cover is provided with a peripheral wall around the outer edge of the installation surface, and the peripheral wall surrounds the outer edge of the front air net.
[0008] In one or more embodiments, the front air net includes a plurality of annular bodies arranged at intervals from inside to outside. An air passing area is formed between the annular bodies, and the annular bodies are connected by a plurality of connecting ribs.
[0009] In one or more embodiments, the plurality of annular bodies, connecting ribs and hooks are injection-molded into an integral structure.
[0010] Compared with the background technology, the utility model has the following effects: the front air net installation structure can be used to facilitate users to remove the front air net for cleaning, and clean the fan blades to avoid dust accumulation and health problems, and has the advantages of easy installation and disassembly.
Brief Description of the Drawings
[0011] Figure 1 This is a schematic diagram of the structure of the utility model after the front air net and the rear net cover are assembled;
[0012] Figure 2 It is a schematic structural diagram of the utility model after the front air net is disassembled from the rear net cover. [Specific implementation method]
[0013] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.
[0014] See attached Figure 1-2 The present application provides a front wind net installation structure of a desktop fan, which includes a rear net cover 1 and a front wind net 2. The front side of the rear net cover is provided with a mounting surface 3, and a plurality of bayonet holes 4 are distributed on the mounting surface. The front wind net 2 is provided with a hook 5 at a position corresponding to the bayonet hole. The hook cooperates with the bayonet hole to install the front wind net on the rear net cover. The installation of the front wind net is realized by adopting the cooperation of the hook and the bayonet hole. The front wind net has the advantages of easy installation and disassembly, which is convenient for users to clean the front wind net after disassembly and installation, and convenient for cleaning the fan blades.
[0015] The multiple bayonet holes 4 are partially arranged on the left and right sides of the installation surface 3, and at least one of the multiple bayonet holes is arranged on the upper part of the installation surface 3. The hook 5 is arranged upward. During installation, first align the hook with the bayonet, then insert and pull the front air net upward so that the hook buckles the bayonet to complete the installation.
[0016] The front wind net 2 is connected and fixed to the rear net cover 1 by screws 10, and a screw hole 6 is provided on the mounting surface 3. A mounting hole 7 is provided at the position corresponding to the screw hole of the front wind net 2. The screws are used to further install and fix it, which can prevent the hook and the bayonet from suddenly falling off, causing the front wind net to be removed and the fan blades to be exposed.
[0017] The rear mesh cover 1 is provided with a peripheral wall 8 around the outer edge of the mounting surface, and the peripheral wall surrounds the outer edge of the front air mesh 2. The peripheral wall can surround and protect the front air mesh, and strengthen the tightness of the connection between the front air mesh and the rear mesh cover.
[0018] The front air grille 2 includes a plurality of annular bodies 21 arranged at intervals from the inside to the outside. An air passing area 9 is formed between the annular bodies. The annular bodies are connected by a plurality of connecting ribs 22. The plurality of annular bodies 21, the connecting ribs 22 and the hooks 5 are integrally formed by injection molding. Using this structure for the front air grille can ensure uniform air outlet, and the integrally injection-molded front air grille has a light overall structure and low manufacturing cost.
[0019] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modification or change made by those of ordinary skill in the art according to the content disclosed by the present invention shall be included in the protection scope recorded in the claims.
