DETAILED DESCRIPTION

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the drawings in the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0023] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can refer to the same reference numerals and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed.

[0024] Please refer to Figures 1 to 4 The embodiment of the present application provides a net cover assembly 10, which comprises a rear net 100 and a front net 200. One of the rear net 100 and the front net 200 is provided with a first positioning member 300 and a first magnetic attraction member 500, and the other is provided with a second positioning member 400 and a second magnetic attraction member 600. The front net 200 is detachably connected to the rear net 100. When the front net 200 is connected to the rear net 100, the second positioning member 400 is positioned and matched with the first positioning member 300, and the second magnetic attraction member 600 is magnetically attracted and matched with the first magnetic attraction member 500.

[0025] In this way, the magnetic attraction and positioning cooperation is used instead of the traditional screw connection, so that the user can more easily and quickly disassemble or install the net cover assembly 10, and the user's use convenience is improved.

[0026] In addition, even without tools, the user can quickly separate the rear net 100 and the front net 200, which facilitates cleaning of the impeller while ensuring the safety of the operation.

[0027] Moreover, the positioning cooperation between the first positioning member 300 and the second positioning member 400 ensures that the rear net 100 and the front net 200 will not easily separate due to vibration and other reasons when the fan is working, and the magnetic attraction member provides additional fixing force, enhancing the stability of the overall structure.

[0028] In some embodiments, the number of first positioning members 300, the number of second positioning members 400, the number of first magnetic attraction members 500, and the number of second magnetic attraction members 600 can all be multiple, wherein the number of second positioning members 400, the number of first magnetic attraction members 500, and the number of second magnetic attraction members 600 are all adapted to the number of first positioning members 300.

[0029] In some embodiments, the first positioning member 300 and the second positioning member 400 can be in the form of protrusions and grooves, that is, one component (for example, the rear net 100) is provided with protrusions, and the other component (for example, the front net 200) is provided with corresponding grooves, and the two are positioned by precise matching. This helps to ensure that the two parts are correctly aligned and can provide a guide function during assembly.

[0030] In some embodiments, the second magnetic attraction member 600 and the first magnetic attraction member 500 can be permanent magnets or electromagnets. When the rear net 100 and the front net 200 are close, the magnetic force will automatically attract them and keep them together, so that no additional mechanical fasteners such as screws are needed. The position of the first magnetic attraction member 500 should be coordinated with the first positioning member 300, and the position of the second magnetic attraction member 600 should be coordinated with the second positioning member 400 to ensure optimal attraction force and stability.

[0031] In some embodiments, the first positioning member 300 is provided with a first accommodating space, and the first magnetic attraction member 500 is arranged in the first accommodating space. In this way, arranging the first magnetic attraction member 500 in the first accommodating space inside the first positioning member 300 can effectively prevent the first magnetic attraction member 500 from falling off during long-term use or under external force, increasing the durability and reliability of the entire mesh cover assembly 10.

[0032] In addition, the first magnetic attraction member 500 is hidden in the accommodating space, avoiding external visible screws or other fixing devices, improving the appearance neatness and aesthetics of the product. Pre-installing the first magnetic attraction member 500 into the first accommodating space of the first positioning member 300 can simplify the assembly steps during production, reduce assembly time, and improve efficiency.

[0033] Moreover, the first accommodating space provides physical protection for the first magnetic attraction member 500, reducing the risk of damage due to collision or friction, and prolonging its service life.

[0034] The second positioning member 400 is provided with a second accommodating space, and the second magnetic attraction member 600 is arranged in the second accommodating space. In this way, the second magnetic attraction member 600 is arranged in the second accommodating space inside the second positioning member 400, which can effectively prevent the second magnetic attraction member 600 from falling off during long-term use or under external force, thereby increasing the durability and reliability of the entire mesh cover assembly 10.

[0035] In addition, the second magnetic attraction member 600 is hidden in the accommodating space, avoiding external visible screws or other fixing devices, thereby improving the appearance neatness and aesthetics of the product. The second magnetic attraction member 600 is pre-installed in the second accommodating space of the second positioning member 400, which can simplify the assembly steps during production, reduce the assembly time, and improve the efficiency.

[0036] Moreover, the second accommodating space provides physical protection for the second magnetic attraction member 600, reducing the risk of damage caused by collision or friction, and prolonging the service life.

[0037] In some embodiments, the first accommodating space has a first mounting hole, and the outer diameter of the first magnetic attraction member 500 is greater than the hole diameter of the first mounting hole, so that the first magnetic attraction member 500 is almost impossible to accidentally fall out of the first accommodating space after assembly.

[0038] The second accommodating space has a second mounting hole, and the outer diameter of the second magnetic attraction member 600 is greater than the hole diameter of the second mounting hole, so that the second magnetic attraction member 600 is almost impossible to accidentally fall out of the second accommodating space after assembly.

[0039] It can be understood that the material around the mounting hole (the first mounting hole or the second mounting hole) can be expanded by heating, so as to more easily install the magnetic attraction member (the first magnetic attraction member 500 or the second magnetic attraction member 600), and the material shrinks after cooling, thereby completing the assembly.

[0040] In some embodiments, when the front mesh 200 is connected to the rear mesh 100, the end of the second positioning member 400 is inserted into the first mounting hole. In this way, through the positioning cooperation between the end of the second positioning member 400 and the first mounting hole, it can be ensured that the rear mesh 100 and the front mesh 200 can be accurately aligned when connected, thereby avoiding the problems of functional failure or appearance inconsistency caused by position deviation.

[0041] In addition, the user only needs to align the second positioning member 400 with the first mounting hole during installation, and the correct connection can be completed, without the need for additional calibration or adjustment, thereby reducing the possibility of misoperation.

[0042] In some embodiments, the first receiving space inside the first positioning member 300 contains a first mounting hole, which is designed to have a diameter and shape that can accept the end of the second positioning member 400. The mounting hole can have a slight chamfer or taper around it to help guide the second positioning member 400 to easily enter, and once fully inserted, to form a tight fit.

[0043] In some embodiments, the second positioning member 400 can be a protruding structure extending from the front mesh 200, with its end designed to have a form that precisely matches the first mounting hole. For example, if the first mounting hole is circular, then the end of the second positioning member 400 should also be cylindrical, with a diameter slightly smaller than the hole diameter of the mounting hole, to ensure smooth insertion and a tight fit.

[0044] In some embodiments, the first positioning member 300 is integrally formed with the back mesh 100; and the second positioning member 400 is integrally formed with the front mesh 200. In this way, due to the reduction in the number of independent components, the integrally formed design reduces the possibility of failure caused by loose or missing parts, increasing the reliability of the product. In addition, by molding at one time through a mold, the number of parts and assembly steps is reduced, reducing production costs and improving production efficiency.

[0045] The first positioning member 300 can be directly used as a part of the back mesh 100, and manufactured together in an injection molding or other molding process. For example, if the back mesh 100 is made of plastic, the complete shape including the first positioning member 300 can be designed in the injection mold, so that the two become an indivisible whole.

[0046] The second positioning member 400 can also be molded at the same time as the front mesh 200. For a metal front mesh 200, it can be integrally formed through processes such as stamping or casting; for a plastic front mesh 200, it can be integrally formed through injection molding.

[0047] In some embodiments, the rear net 100 comprises a mesh cover portion 110 and a first connecting portion 120 connected thereto, the first connecting portion 120 being disposed around the edge of the mesh cover portion 110 and extending along the axial direction of the mesh cover portion 110, and the first positioning member 300 is disposed on the first connecting portion 120; the front net 200 comprises a mesh plate portion 210 and a second connecting portion 220 connected thereto, the first connecting portion 120 being disposed around the edge of the mesh plate portion 210 and extending along the radial direction of the mesh cover portion 110, and the second positioning member 400 is disposed on the second connecting portion 220, and the second connecting portion 220 is detachably connected to the first connecting portion 120. The mesh cover portion 110 of the rear net 100 is a mesh structure made of metal or plastic, and the first connecting portion 120 around the edge thereof is a thicker material extending along the axial direction of the mesh cover portion 110. The first positioning member 300 is located on the inner side of the first connecting portion 120, which ensures that the front net 200 can be accurately aligned and mechanically constrained when connected. The mesh plate portion 210 of the front net 200 is also a mesh structure, and the second connecting portion 220 around the edge thereof is a material extending along the radial direction of the mesh cover portion 110. The second positioning member 400 is located on the second connecting portion 220 and is designed to accurately match the first positioning member 300 of the rear net 100.

[0048] In some embodiments, the first connecting portion 120 is formed with an opening 121, and the second connecting portion 220 is inserted into the opening 121. In this way, through the design of the opening 121 and the insertion, the user can easily insert the front net 200 into the rear net 100 without using any tools, greatly simplifying the installation and disassembly process.

[0049] In addition, the design of the opening 121 provides a clear assembly guide, ensuring that the second connecting portion 220 can be accurately inserted into the specified position, avoiding assembly problems caused by positional deviation.

[0050] The size of the opening 121 is slightly larger than the maximum cross-section of the second connecting portion 220, to ensure that no excessive force is applied during insertion. When the second connecting portion 220 is completely inserted into the opening 121, a tight mechanical fit is formed between the two, and the first positioning member 300 and the second positioning member 400 are also positioned, and the first magnetic member 500 and the second magnetic member 600 are magnetically attracted.

[0051] In some embodiments, the rear net 100 further comprises a plurality of support portions, which are arranged along the circumference of the first connecting portion 120 in sequence and at intervals, each of the support portions being arranged at the connection between the mesh cover portion 110 and the first connecting portion 120 and located at the opening 121, and when the second connecting portion 220 is connected to the first connecting portion 120, the second connecting portion 220 abuts against the plurality of support portions. In this way, the presence of the plurality of support portions significantly increases the connection strength between the first connecting portion 120 and the mesh cover portion 110, so that the entire mesh cover assembly 10 is more robust and durable.

[0052] In addition, when the second connecting portion 220 is inserted into the opening 121 and abuts against the support portions, an additional mechanical constraint is formed, which ensures that the connection between the front and rear nets 200 is more tight and reduces the risk of loosening or falling off.

[0053] The mesh cover portion 110, as the main part of the rear net 100, is generally a grid structure and is used to block foreign matters from entering the inside of the fan. The first connecting portion 120 is arranged around the edge of the mesh cover portion 110 and extends along the axial direction of the mesh cover portion 110, forming a ring-shaped structure. The first connecting portion 120 is provided with an opening 121, which is specially designed to receive the second connecting portion 220 of the front net 200. The mesh plate portion 210 of the front net 200 is also a grid structure, and the second connecting portion 220 is a ring of material arranged around the edge thereof and extending along the radial direction of the mesh cover portion 110. The second connecting portion 220 is designed to perfectly match the opening 121, and after being inserted, it is tightly connected to the first connecting portion 120 of the rear net 100 and abuts against the support portions.

[0054] In some embodiments, the first magnetic member 500 and the second magnetic member 600 are both magnets. The magnets have strong attractive force and can quickly and stably connect the rear net 100 and the front net 200 together, improving the assembly speed and connection efficiency.

[0055] The utility model embodiment further provides a fan, which comprises the mesh cover assembly 10 and the impeller of any of the above embodiments, and the impeller is rotatably arranged in the inside of the mesh cover assembly 10. The structural design of the mesh cover assembly 10 helps to guide the airflow to pass through the impeller more uniformly, improving the working efficiency and cooling effect of the fan.

[0056] The fan further comprises a motor, and the output shaft of the motor penetrates through the front net 200 and is connected to the impeller so as to drive the impeller to rotate.

[0057] The device embodiments described above are merely illustrative, in which the units illustrated as separate components can or can not be physically separate, and the components illustrated as units can or can not be physical units, i.e., can be located in one place, or can be distributed to multiple network units. Part or all of the modules can be selected according to actual needs to achieve the purpose of the embodiment.
