[0023] The specific embodiments of the utility model will be described in detail below. It should be noted that the embodiments described here are only part of the embodiments of the utility model, not all of them. Based on the following embodiments, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides the following technical solutions:

[0025] Embodiment 1:

Through the design of magnetic suction, the filter screen can be quickly assembled when installing the restaurant fan light, and the design of the filter screen can prevent dust from entering the fan motor to affect the working safety of the fan, and at the same time, it can effectively dissipate the heat of the fan light, facilitate disassembly and cleaning, and extend the service life of the restaurant fan light.

[0027] like Figure 2 As shown, the two joint surfaces of the mesh frame 1 are respectively provided with a lower guide card 1.1, an upper guide card 1.2, a lower guide socket 1.3, and an upper guide socket 1.4, the cards and the sockets are respectively arranged on the same joint surface, the lower guide card 1.1 and the lower guide socket 1.3 have the same vertical height, and the horizontal points are symmetrical on both sides of the central axis of the mesh frame 1, the upper guide card 1.2 and the upper guide socket 1.4 have the same vertical height, and the horizontal points are symmetrical on both sides of the central axis of the mesh frame 1.

[0028] like Figure 4 As shown, when two filter screen panels are assembled, assuming that the two panels are A and B, the lower guide card 1.1 and the upper guide card 1.2 of A are respectively inserted into the lower guide jack 1.3 and the upper guide jack 1.4 of B, and the lower guide card 1.1 and the upper guide card 1.2 of B are respectively inserted into the lower guide jack 1.3 and the upper guide jack 1.4 of A, the jacks are provided with grooves, and the cards are provided with buckles. The jack grooves and the card buckles have the same size and the guides are opposite, so that the two filter screen panels can be aligned and assembled together, which plays a role in limiting and stabilizing the structure.

[0029] like Figure 3As shown, circular grooves are provided on the two joint surfaces of the mesh frame 1, and the grooves on a single joint surface are distributed at intervals. The grooves on the joint surface on one side of the mesh frame 1 are larger than the grooves on the joint surface on the other side. The magnetic sheet 3 and the magnet 4 are fixed in the grooves accordingly. The magnetic sheet 3 is a galvanized iron sheet with a diameter of 5 to 5.5 mm, and the magnet 4 is a strong NdFeB magnet with a diameter of 6 to 6.5 mm. The diameters of the magnetic sheet 3 and the magnet 4 are different. In order to ensure a fool-proof design during mold encapsulation and injection molding production, it is ensured that the installation positions of the magnetic sheet 3 and the magnet 4 are prevented from being misaligned during the injection molding.

[0030] Galvanizing can improve the corrosion resistance of the iron sheet and prevent it from moisture, rust or corrosion. Therefore, when there is water vapor in the fan lamp, the iron sheet is more durable; galvanizing can reduce the production cost of the magnetic sheet 3, and the iron sheet maintains a certain magnetic property, which can provide the necessary adsorption force for magnetic installation; the magnet 4 adopts a strong NdFeB magnet, which is a rare earth permanent magnet material with very strong magnetic properties and can provide sufficient magnetic adsorption force for installation; the NdFeB magnet has high chemical stability, is not easy to oxidize and corrode, and can maintain stable magnetic properties; the NdFeB magnet has a high magnetic energy density, so the volume of the magnet can be reduced during design, saving materials and costs; through the magnetic attraction and groove buckle design, the convenience of disassembly of the filter plate is increased, while the firmness of the overall structure is maintained, which is beneficial to improving the service life of the fan lamp.

[0031] like Figure 5 As shown, the mesh frame 1 is a semi-conical sheet structure, the upper port of which is a semicircle with a smaller radius, and the lower port is a semicircle with a larger radius. The side surface of the mesh frame 1 is an inwardly concave arc structure, which increases the contact area between the filter and the air. There are a number of strip air windows on the side surface, which are evenly distributed along the side surface, with the same spacing between each air window, and the symmetry axis of the strip air window passes through the center of the frame port.

[0032] The strip air louver windows are evenly arranged on the mesh frame 1 in a centrally symmetrical manner. The arc angle radius of the strip air louver window near the frame port center end is 70% to 80% of the arc angle radius of the farthest center end, and the symmetry axis of the strip air louver passes through the center of the frame port. The arc angle of the strip air louver window near the frame port center end is close to the upper edge of the mesh frame 1, and the other end has an edge thickness of 2 to 3 cm with the lower edge of the mesh frame 1, which ensures the structural stability of the fan lamp and the ventilation and heat dissipation effects.

[0033] The diameter of the upper port of the assembled mesh frame 1 is 50% to 60% of the diameter of the lower port, and its side surface is concave inward, and the whole is in a trumpet shape. The concave side surface increases the heat dissipation area and enhances the filtering effect.

[0034] The screen frame 1 is an integrally formed structure of an injection molding machine, which improves production efficiency and product consistency.

[0035] like Figure 6 As shown, two decorative ribs 1.5 are provided on both sides of the middle air louver window on the outer surface of the mesh panel frame 1. As the fan lamp in the restaurant rotates, oil smoke will be attached for a long time, and black oil stains will be accumulated on the filter panel structure for a long time. The black oil stains will make the splicing gap between the two mesh panel frames 1 unclear, and misjudgment may occur during disassembly. The operator may force the disassembly at a non-splicing position, causing damage to the filter panel structure. The provision of decorative ribs 1.5 can remind the operator that this is a detachable position, and the two mesh panel frames 1 can be separated by holding or clamping this part with tools.

[0036] An annular groove is provided at the upper end of the mesh frame 1, and the lower end is horizontally provided below. An annular protrusion with a triangular cross-section is provided on the inner side of the lower port. The grooves on the splicing surface of the mesh frame 1 are respectively arranged at the bottom of the annular groove and the annular protrusion. The annular groove on the upper end surface of the mesh frame 1 forms an installation groove after the two pieces are spliced ​​together, and other auxiliary components can be installed. The protrusion on the lower end surface of the mesh frame 1 forms an arc-shaped annular groove with the inner side surface, and its shape is adapted to the shape of the panel protrusion of the restaurant fan light, so as to facilitate the installation and combination of the mesh frame 1 and the fan light.

[0037] like Figure 7 As shown, when the two filter screen structure magnets 4 are aligned with the magnetic attraction sheet 3, and the plug-in card is aligned with the plug-in hole, a complete fan light filter screen is formed.

[0038] Embodiment 2:

[0039] A restaurant fan light filter screen structure comprises a screen frame 1, a main body of the screen frame 1 is provided with a plurality of strip-shaped air windows, the air windows of the screen frame 1 are covered with a filter screen 2, and a plurality of magnetic suction sheets 3 and a plurality of magnets 4 are installed on the screen frame 1.

[0040] The filter screen plate structure is a screen plate that is semicircular and fan-shaped when viewed from above, wherein the upper port is a semicircle with a smaller radius, and the lower port is a semicircle with a larger radius, and the overall structure is a trumpet-shaped structure.

[0041] The side surface of the filter plate structure is an inwardly concave arc structure, which increases the contact area between the filter and the air. There are several strip air windows on the side surface, which are evenly distributed along the side surface. The spacing between each air window is the same. The symmetry axis of the strip air window passes through the center of the frame port. A filter 2 is provided in the strip air window. The filter 2 is arranged inside the interlayer of the filter plate structure. The internal concave surface structure and the design of the air window window improve the heat dissipation performance of the motor inside the fan lamp and prevent dust from entering the fan lamp motor.

[0042] The upper port of the filter plate structure is provided with a horizontal mounting groove, which is used to install and fix the rear cover of the fan light. The lower port of the filter plate structure is provided with a triangular inclined platform, which increases the smoothness of the fan light's lines. The lower surface of the lower port is horizontal and straight, which is convenient for installation with the fan light body.

[0043] A magnetic sheet installation groove is provided on the left end face of the filter screen structure, and a magnetic sheet 3 is embedded in the installation groove. The two magnetic sheets 3 are respectively located at the edge position consistent with the horizontal height of the upper port and the edge position of the inclined platform of the lower port; the magnetic sheet 3 is a galvanized iron sheet with a diameter of 5 mm; the galvanizing treatment can improve the corrosion resistance of the iron sheet and prevent it from moisture, rust or corrosion, so when there is water vapor in the fan light, the iron sheet is more durable; the galvanizing treatment can reduce the production cost of the magnetic sheet 3, and the iron sheet maintains a certain magnetic property, which can provide the necessary adsorption force for magnetic installation.

[0044] The right end face of the filter plate structure is provided with a magnet 4, which is a strong NdFeB magnet. NdFeB is a rare earth permanent magnet material with very strong magnetic properties, which can provide sufficient magnetic adsorption for installation; NdFeB magnets have high chemical stability, are not easy to oxidize and corrode, and can maintain stable magnetic properties; NdFeB magnets have high magnetic energy density, so the volume of the magnet can be reduced during design, saving materials and costs. Therefore, galvanized iron sheets as magnetic sheets have good corrosion resistance and cost advantages, while NdFeB as magnets are selected for such applications due to their strong magnetic properties, stability and size advantages. The combination of these two materials ensures that a durable and effective magnetic connection is provided in the design of the utility model fan lamp.

[0045] An upper guide socket 1.4 and a lower guide socket 1.3 are provided on the joint surface of each filter screen panel structure, and the upper guide socket 1.4 is located at 1 / 3 of the upper middle part of the left end surface, and the lower guide socket 1.3 is located at 1 / 3 of the lower middle part of the left end surface; an upper guide socket 1.2 and a lower guide card 1.4 are provided on the right end surface of each filter screen panel structure, and the upper guide card 1.1 is located at 1 / 3 of the upper middle part of the left end surface, and the lower guide socket 1.1 is located at 1 / 3 of the lower middle part of the left end surface, the magnetic suction sheet 3 and the magnet 4 as well as the upper guide socket 1.4, the lower guide socket 1.3, the upper guide socket 1.2 and the lower guide card 1.4 are respectively arrayed on the left end surface and the right end surface of the filter screen panel structure, and the sockets and the cards are plugged in according to the guide, which increases the firmness of the structure.

[0046] The two fan light filter panels are magnetically attracted, wherein the installation positions of the magnetic sheet 3 and the magnet 4 correspond to each other. When the fan light filter panel is installed, the magnetic sheet 3 and the magnet 4 attract each other, and cooperate with the plug-in connection of the plug-in card and the plug-in socket to form a firm filter panel structure.

[0047] The magnetic sheet 3 and the magnet 4 of the two filter screen structures are located in the same horizontal plane. The magnetic sheet and the magnet are attracted and connected on the horizontal plane. The plug-in cards with different orientations are plugged into the jacks. Since the assembled jacks and the plug-in cards have different orientations, a firm plug-in structure is formed.

[0048] The two-piece filter screen structure is combined with a magnetic suction and a socket to form a complete circular screen structure. Two decorative ribs 1.5 are provided on both sides of the middle air vent window on the outer surface of the screen frame 1. As the fan light in the restaurant rotates, oil smoke will be attached to the filter screen structure for a long time, which will accumulate on the filter screen structure for a long time to form black oil stains. The black oil stains will make the joint gap between the two screen frames 1 unclear, and misjudgment may occur during disassembly. The operator may force the disassembly at a non-joined position, causing damage to the filter screen structure. The decorative ribs 1.5 can remind the operator that this is a detachable position, and the two screen frames 1 can be separated by holding or clamping this part with tools.

[0049] Based on the above embodiments, the present application proposes a fan light filter plate structure. Through the magnetic suction design, the filter plate can be quickly assembled when installing the restaurant fan light. The design of the filter 2 can prevent dust from entering the fan motor and affecting the safety of the fan. At the same time, it can also effectively dissipate the heat of the fan light, facilitate disassembly and cleaning, and extend the service life of the restaurant fan light.
