The terms used in the description of this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0057] Please refer toFigure 1 - Figure 2 , an embodiment of the present application provides an electrical appliance. The electrical appliance includes an electrical appliance main body (not shown in the figure) and a filter net 200 magnetically connected to the electrical appliance main body (not shown in the figure). Specifically, a magnet (not shown in the figure) can be provided on the electrical appliance main body, and at least part of the filter net 200 is made of a metal material so that the filter net 200 is magnetically adsorbed by the magnet on the electrical appliance main body. Or, a magnet can be provided on the filter net 200, and at least part of the electrical appliance main body is made of a metal material so that the filter net 200 can be magnetically adsorbed on the electrical appliance main body through the magnet. Or, there are magnets on both the filter net 200 and the electrical appliance main body, and the magnets on the filter net 200 and the electrical appliance main body magnetically attract each other so that the filter net 200 can be magnetically adsorbed on the electrical appliance main body. This embodiment does not make a limitation on this.

[0058] In this embodiment, the electrical appliances are all electrical appliances including the filter net 200. For example, the electrical appliance can be a range hood, an air conditioner, an air purifier, and other electrical appliances with a filter net 200. The filter net 200 is used to filter impurities in the air such as large particles, oil stains, and water vapor. The specific function of the filter net 200 is different from the electrical appliance to which the filter net 200 is applicable. The following takes the electrical appliance as a range hood as an example for illustration.

[0059] Furthermore, the electrical appliance further includes a quick-release structure 100. The quick-release structure 100 is connected to the filter net 200 and is used to abut against the electrical appliance main body. Or, the quick-release structure 100 is connected to the electrical appliance main body and abuts against the filter net 200. By operating the quick-release structure 100, the filter net 200 and the electrical appliance main body can be separated from each other to form a gap, so as to weaken the magnetic attraction between the filter net 200 and the electrical appliance main body, thereby more conveniently and quickly removing the filter net 200 from the electrical appliance main body, and improving the convenience and efficiency of the disassembly process of the filter net 200. After the filter net 200 is removed, the filter net 200 can be cleaned, or a new filter net 200 can be replaced, or the part of the electrical appliance main body that was previously blocked by the filter net 200 can be cleaned or repaired. The quick-release structure 100 and the filter net 200 form a filter net assembly 1000.

[0060] Please refer to Figure 3 - Figure 6 , in some embodiments, the quick-release structure 100 includes a rotating shaft 10 and a rotating member 20.

[0061] The rotating shaft 10 is connected to one of the filter net 200 and the electrical appliance main body, so that the rotating shaft 10 can be fixed to the filter net 200 or the electrical appliance main body. Specifically, the rotating shaft 10 can be directly connected to the filter net 200, that is, the rotating shaft 10 is directly fixed to the filter net 200. The rotating shaft 10 can also be indirectly connected to the filter net 200 through other components to be indirectly fixed to the filter net 200. Similarly, the rotating shaft 10 can be directly connected to the electrical appliance main body, that is, the rotating shaft 10 is directly fixed to the electrical appliance main body. The rotating shaft 10 can also be indirectly connected to the electrical appliance main body through other components to be indirectly fixed to the electrical appliance main body.

[0062] The rotating member 20 is rotatably sleeved on the rotating shaft 10, that is, the rotating member 20 can rotate relative to the rotating shaft 10. Of course, the rotating member 20 can also be fixedly connected to the rotating shaft 10. At this time, the rotating member 20 and the rotating shaft 10 rotate together relative to the filter net 200 or the electrical appliance main body.

[0063] Specifically, the rotating member 20 includes a driving end 2311 and an abutting end 221 that are far away from each other. The driving end 2311 can be acted on by electric, pneumatic or manual means to make the rotating member 20 rotate. When the driving end 2311 is driven, the rotating member 20 rotates and drives the abutting end 221 to abut against the filter net 200 or the electrical appliance main body. It can be understood that when the rotating shaft 10 is installed on the filter net 200, the abutting end 221 abuts against the electrical appliance main body. When the rotating shaft 10 is installed on the electrical appliance main body, the abutting end 221 abuts against the filter net 200. In this way, no matter the abutting end 221 abuts against the electrical appliance main body or the filter net 200, the filter net 200 and the electrical appliance main body can be relatively far away from each other to form a gap, so as to weaken the magnetic suction force between the filter net 200 and the electrical appliance main body, so that the filter net 200 can be more conveniently and quickly detached from the electrical appliance main body, and the convenience and efficiency of detaching the filter net 200 relative to the electrical appliance main body can be improved.

[0064] Please refer to Figure 4 In some embodiments, on the basis that the rotating shaft 10 is directly or indirectly fixedly connected to the filter net 200, the rotating member 20 includes a rotating part 21 and an abutting part 22.

[0065] The rotating part 21 is rotatably sleeved on the rotating shaft 10, and the rotating part 21 also has a driving end 2311. When the driving end 2311 is driven, the rotating part 21 can rotate relative to the rotating shaft 10.

[0066] The top abutting portion 22 is connected to one end of the rotating portion 21 away from the driving end 2311. That is, the driving end 2311 and the top abutting portion 22 are located on two opposite sides of the rotating portion 21. The top abutting portion 22 further has a top abutting end 221. When the driving end 2311 is driven, the entire rotating portion 21 can rotate relative to the rotating shaft 10. At this time, the top abutting portion 22 and its top abutting end 221 also rotate. According to the lever principle, the rotating direction of the top abutting portion 22 and its top abutting end 221 is opposite to the rotating direction of the driving end 2311. In this way, by using the lever principle, driving the top abutting portion 22 to rotate through the driving end 2311 will be more labor-saving and more convenient for the user to perform manual operations.

[0067] Furthermore, the top abutting portion 22 and the rotating portion 21 are arranged at an angle so that the top abutting portion 22 extends from the rotating portion 21 towards the electrical appliance body. In this way, in the rotating direction of the top abutting portion 22, the distance between the top abutting end 221 and the electrical appliance body is closer, and the rotating stroke of the top abutting end 221 from the initial position where it does not abut against the electrical appliance body to the position where it abuts against the electrical appliance body is shorter. In this way, the user can operate the driving end 2311 to rotate a shorter stroke, and the top abutting end 221 can abut against the electrical appliance body, further improving the convenience and efficiency of the disassembly process of the filter net 200.

[0068] In some embodiments, the rotating portion 21 includes a rotating plate 23 and a shaft hole plate 24.

[0069] The rotating plate 23 is in a plate shape to facilitate the arrangement of the shaft hole plate 24 on the rotating plate 23. The rotating plate 23 has a driving end 2311. By operating the driving end 2311, a force can be applied to the rotating plate 23 to make the rotating plate 23 rotate.

[0070] The shaft hole plate 24 is connected to the surface of the rotating portion 21. Exemplarily, the shaft hole plate 24 can be arranged on the surface of the rotating plate 23 facing the electrical appliance body. The shaft hole plate 24 has a shaft hole 24a for the rotating shaft 10 to pass through. In this way, the rotating plate 23 realizes the function of rotating relative to the rotating shaft 10 through the cooperation between the shaft hole plate 24 and the rotating shaft 10.

[0071] Furthermore, the abutting top 22 is a column, one end of which is connected to an end of the rotating plate 23 away from the driving end 2311, that is, the column and the driving end 2311 are respectively located on two sides of the rotating plate 23 away from each other. In this way, when the driving end 2311 is driven, the rotating plate 23 can drive the column to rotate, so that the abutting top 211 of the column abuts against the electrical body. By setting the abutting top 22 as a column, the contact area between the column and the electrical body is smaller. When the same force is applied to the driving end 2311, the smaller contact area between the column and the electrical body can make the force of the column on the unit contact area of ​​the electrical body greater, and the reaction force of the electrical body on the column is also greater. The reaction force is transmitted to the filter 200 through the column, the rotating plate 23 and the rotating shaft 10, so that the filter 200 is away from the electrical body, that is, it is easier for the filter 200 to have a gap with the electrical body, thereby achieving separation between the two.

[0072] Please continue reading Figure 4 In some embodiments, the rotating plate 23 includes a driving sub-plate 231 and a connecting sub-plate 232 .

[0073] The driving sub-board 231 has a driving end 2311 for being manually operated or driven by a user.

[0074] The connecting sub-plate 232 connects the column and the driving sub-plate 231, and along the length direction AA of the rotating plate 23, the connecting sub-plate 232 and the driving sub-plate 231 are respectively located on both sides of the shaft hole plate 24. According to the lever principle, the rotation direction of the driving sub-plate 231 when being driven is opposite to the rotation direction of the connecting sub-plate 232 and the column. For example, when the driving sub-plate 231 is operated to rotate downward, the connecting sub-plate 232 and the column will rotate upward.

[0075] Please continue reading Figure 4 Furthermore, in the driving sub-board 231, a surface located on the same side as the shaft hole plate 24 is provided with a first anti-slip protrusion 2312, that is, a first anti-slip protrusion 2312 is provided on the upper surface of the driving sub-board 231. In this way, the friction between the user's fingers and the first anti-slip protrusion 2312 can be increased, which is convenient for the user's fingers to bend the driving sub-board 231 downward, and the risk of the user's fingers being separated from the upper surface of the driving sub-board 231 is reduced. In particular, when the electrical device is a range hood, there may be oil stains on the upper surface of the driving sub-board 231, resulting in a small friction between the upper surface of the driving sub-board 231 and the user's fingers. By providing the first anti-slip protrusion 2312, even if there is oil stains on the upper surface of the driving sub-board 231, the user's fingers are not easy to separate from the driving sub-board 231.

[0076] See also Figure 5 - Figure 6, in some embodiments, on the sub - connecting plate 232, a second anti - slip protrusion 2321 is provided on the surface facing away from the shaft - hole plate 24, that is, the second anti - slip protrusion 2321 is provided on the lower surface of the sub - connecting plate 232. In this way, the frictional force between the user's finger and the second anti - slip protrusion 2321 can be increased, facilitating the user's finger to drive the sub - connecting plate 232 upward. That is, in the embodiments of the present application, the sub - connecting plate 232 can also be directly driven to rotate upward, causing the column body to follow the sub - connecting plate 232 and upwardly abut against the electrical appliance main body, so that a gap is generated between the filter screen and the electrical appliance main body, without the need to operate the driving sub - plate 231.

[0077] Therefore, similarly, the second anti - slip protrusion 2321 is provided on the lower surface of the sub - connecting plate 232. In this way, the frictional force between the user's finger and the second anti - slip protrusion 2321 can be increased, facilitating the user's finger to rotate and drive the sub - plate 231 upward, reducing the risk of the user's finger detaching from the lower surface of the sub - connecting plate 232. Especially when the electrical appliance is a range hood, there may be oil stains on the lower surface of the sub - connecting plate 232, resulting in a small frictional force between the lower surface of the sub - connecting plate 232 and the user's finger. By providing the second anti - slip protrusion 2321, even if there are oil stains on the lower surface of the sub - connecting plate 232, the user's finger is not likely to detach from the sub - connecting plate 232.

[0078] Please refer to Figure 4 Or Figure 6 , in some embodiments, the quick - release structure 100 further includes a mounting member 30. The rotating shaft 10 is disposed on the mounting member 30, and the mounting member 30 is used for fixedly connecting with the filter net 200. That is, the rotating shaft 10 is indirectly mounted on the filter net 200 through the mounting member 30. In this way, on the one hand, the structure of the mounting member 30 can be flexibly set, facilitating the installation of the rotating shaft 10. On the other hand, the interference of the filter net 200 on the rotating shaft 10 during the rotation process can also be avoided.

[0079] Please continue to refer to Figure 3 - Figure 6 , in some embodiments, the mounting member 30 includes a mounting cover 31 and a connecting cover 32.

[0080] The mounting cover 31 is in the shape of a cover shell. The mounting cover 31 has a mounting cavity 31a (see Figure 6 ). The rotating shaft 10 is mounted on the cavity wall of the mounting cavity 31a, and a part of the rotating member 20 is located inside the mounting cavity 31a. Specifically, the rotating plate 23 is mounted inside the mounting cavity 31a. By providing the mounting cover 31, the rotating shaft 10 and the rotating plate 23 inside the mounting cover 31 can be protected, reducing the influence of the oil fume of the range hood on the rotating shaft 10 and the rotating plate 23. In addition, when the abutting part 22 (such as a column body) rotates, it can sequentially extend out of the mounting cover 31 and the connecting cover 32 to abut against the electrical appliance main body.

[0081] Please refer to Figure 7 - Figure 8, The connecting cover 32 is connected to the mounting cover 31 and is used to sandwich the filter net 200 with the mounting cover 31 so that the mounting member 30 is fixed to the filter net 200. Specifically, the filter net 200 has a mounting opening 200a. During the installation process of the mounting cover 31, the connecting cover 32, and the filter net 200, the mounting cover 31 moves from bottom to top, and a part of the mounting cover 31 passes through the mounting opening 200a. Other structures of the mounting cover 31 abut against the lower surface of the filter net 200. Then, the connecting cover 32 is moved from top to bottom until it abuts against the mounting cover 31, and then the connecting cover 32 and the mounting cover 31 are fixedly connected by screwing or clamping. In this way, by sandwiching the filter net 200 with the connecting cover 32 and the mounting cover 31, the convenient and rapid installation of the quick-release structure 100 and the filter net 200 is realized.

[0082] Furthermore, the wall of the mounting opening 200a has at least one of a guiding portion 3121 and a guiding groove 200b, and the mounting cover 31 has at least the other of the guiding portion 3121 and the guiding groove 200b, and the guiding groove 200b is in guiding cooperation with the guiding portion 3121. In this way, during the process of the mounting cover 31 moving from bottom to top and being installed on the filter net 200, through the guiding cooperation between the guiding groove 200b and the guiding portion 3121, on the one hand, it can prevent the mounting cover 31 from being installed reversely and realize the anti-fooling function. On the other hand, the guiding groove 200b and the guiding portion 3121 guide each other, which can improve the assembly efficiency between the mounting cover 31 and the filter net 200.

[0083] Please refer to Figure 4 , Specifically, the mounting cover 31 has a first mounting hole 311a, the connecting cover 32 has a second mounting hole 32a, and the quick-release structure 100 further includes a screwing member (not shown in the figure). The screwing member passes through the first mounting hole 311a and the second mounting hole 32a so that the connecting cover 32 and the mounting cover 31 are screwed together by the screwing member.

[0084] In a specific embodiment, both the first mounting hole 311a and the second mounting hole 32a can be through holes. The screwing member includes a screw (not shown in the figure) and a nut (not shown in the figure) that are screwed together. The screw passes through the first mounting hole 311a and the second mounting hole 32a, and the mounting cover 31 and the connecting cover 32 are screwed and locked by the nut and the screw.

[0085] In another specific embodiment, among the first mounting hole 311a and the second mounting hole 32a, at least the first mounting hole 311a is a threaded hole with internal threads. The screw connector includes a screw, and the screw is screwed with at least the first mounting hole 311a to lock the mounting cover 31 and the connecting cover 32. Of course, the second mounting hole 32a can also be a threaded hole that cooperates with the screw. In this way, the screw is screwed with both the first mounting hole 311a and the second mounting hole 32a, and the mounting cover 31 and the connecting cover 32 are connected more stably and tightly.

[0086] Please continue to refer to Figure 4 , in some embodiments, the mounting cover 31 has one of the positioning posts 3111 and the positioning holes 32b, and the connecting cover 32 has the other of the positioning posts 3111 and the positioning holes 32b. Exemplarily, the mounting cover 31 has the positioning posts 3111, and the connecting cover 32 has the positioning holes 32b. The positioning posts 3111 are in positioning cooperation with the positioning holes 32b. In this way, the positioning installation between the connecting cover 32 and the mounting cover 31 is realized, so that the first mounting hole 311a and the second mounting hole 32a can be aligned more quickly, which is convenient for the subsequent installation of the screw connector and improves the installation efficiency between the connecting cover 32 and the mounting cover 31.

[0087] In some embodiments, the mounting cover 31 has a first avoidance hole 312a, and the connecting cover 32 has a second avoidance hole 32c. When the abutting top 22 (cylinder) rotates, it passes through the first avoidance hole 312a and the second avoidance hole 32c to abut against the electrical appliance main body. That is, by providing the first avoidance hole 312a on the mounting cover 31 and simultaneously providing the second avoidance hole 32c on the connecting cover 32, when the abutting top 22 rotates upward, it can pass through the mounting cover 31 and the connecting cover 32 in sequence, so that the abutting top 22 can abut against the electrical appliance main body.

[0088] Please refer to Figure 4 and Figure 6 , in some embodiments, the mounting cover 31 includes a top shell 311 and a surrounding shell 312.

[0089] The surrounding shell 312 has an opening 312b for the movable rotation plate 23. The opening 312b is communicated with the mounting cavity 31a. The rotating part 21 can be installed in the mounting cavity 31a through the opening 312b, and during the rotation process, it can also be rotated out of the mounting cavity 31a through the opening 312b. Both ends of the rotating shaft 10 are installed on two opposite side walls of the surrounding shell 312. The first avoidance hole 312a is at least provided on the surrounding shell 312. In order to avoid interference of the top shell 311 with the abutting top 22, the first avoidance hole 312a can also extend to the top shell 311.

[0090] Please refer to Figure 4The top shell 311 is covered on the top of the surrounding shell 312, and the top shell 311 and the surrounding shell 312 jointly define the installation cavity 31a, and the opening 312b is arranged opposite to the top shell 311. The first installation hole 311a and the positioning column 3111 are arranged on the top shell 311, so that the first installation hole 311a is aligned with the second installation hole 32a on the connecting cover 32, and the positioning hole 32b is convenient for positioning and matching with the positioning column 3111.

[0091] In some embodiments, based on the embodiment that the casing 312 has an opening 312b for the rotating plate 23 to move, as shown in FIG. Figure 6 As shown, the rotating plate 23 can be located as a whole in the installation cavity 31a, that is, the driving sub-plate 231 and the rotating sub-plate are both located in the installation cavity 31a. It is inconvenient for the user's fingers to reach into the installation cavity 31a to rotate the driving sub-plate 231 downward. At this time, the user can first contact the second anti-slip protrusion 2321 on the lower surface of the connecting sub-plate 232 with the fingers of one hand, and rotate the connecting sub-plate 232 upward. Correspondingly, the driving sub-plate 231 rotates downward and out of the opening 312b. At this time, the user's other hand can contact the first anti-slip protrusion 2312 on the upper surface of the driving sub-plate 231 to pry the driving sub-plate 231 downward.

[0092] See also Figure 4 or Figure 6 In some embodiments, the quick-release structure 100 further includes an elastic member 33 .

[0093] The elastic member 33 is sleeved on the rotating shaft 10, and the elastic member 33 is connected to the rotating member 20, and is used to drive the rotating member 20 to reset. Specifically, the elastic member 33 can be a torsion spring, one end of which abuts against the upper surface of the connecting sub-plate 232, and the other end of which abuts against the inner wall surface of the top shell 311. In this way, when the user bends the driving sub-plate 231 to rotate downward, the torsion spring is compressed. When the user releases the driving sub-plate 231, the rotating plate 23 is reset and re-positioned in the installation cavity 31a under the action of the restoring force of the torsion spring. In this way, the rotating plate 23 is normally in the installation cavity 31a to avoid bumping against the user, and at the same time, the overall appearance of the electrical device is more concise and beautiful.
