[0053] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in 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] See also Figure 1-Figure 2 , the embodiment of the present application provides an electrical device, which includes an electrical main body (not shown in the figure) and a filter 200 magnetically connected to the electrical main body (not shown in the figure). Specifically, a magnet (not shown in the figure) can be provided on the electrical main body, and the filter 200 is at least partially made of metal material, so that the filter 200 is magnetically adsorbed by the magnet on the electrical main body, or a magnet can be provided on the filter 200, and the electrical main body is at least partially made of metal material, so that the filter 200 can be magnetically adsorbed on the electrical main body by the magnet, or there are magnets on both the filter 200 and the electrical main body, and the magnets on the filter 200 and the electrical main body are magnetically attracted to each other, so that the filter 200 can be magnetically adsorbed on the electrical main body. This embodiment does not limit this.

[0058] In this embodiment, the electrical equipment is an electrical equipment including a filter 200. For example, the electrical equipment may be a range hood, an air conditioner, an air purifier, or other electrical equipment having a filter 200. The filter 200 is used to filter out impurities in the air such as large particles, oil, and water vapor. The specific function of the filter 200 is different from the type of electrical equipment the filter 200 is suitable for. The following description takes the range hood as an example.

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

[0060] See also 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 200 and the main body of the electrical appliance, so that the rotating shaft 10 can be fixed to the filter 200 or the main body of the electrical appliance. Specifically, the rotating shaft 10 can be directly connected to the filter 200, that is, the rotating shaft 10 is directly fixed to the filter 200, and the rotating shaft 10 can also be indirectly connected to the filter 200 through other components to be indirectly fixed to the filter 200. Similarly, the rotating shaft 10 can be directly connected to the main body of the electrical appliance, that is, the rotating shaft 10 is directly fixed to the main body of the electrical appliance, and the rotating shaft 10 can also be indirectly connected to the main body of the electrical appliance through other components to be indirectly fixed to the main body of the electrical appliance.

[0062] The rotating member 20 is rotatably mounted 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 200 or the electrical appliance body.

[0063] Specifically, the rotating member 20 includes a driving end 2311 and a top end 221 that are far away from each other. The driving end 2311 can be acted on by electric, pneumatic or manual means to rotate the rotating member 20. When the driving end 2311 is driven, the rotating member 20 rotates and drives the top end 221 to abut against the filter 200 or the electrical appliance body. It can be understood that when the rotating shaft 10 is installed on the filter 200, the top end 221 abuts against the electrical appliance body, and when the rotating shaft 10 is installed on the electrical appliance body, the top end 221 abuts against the filter 200. In this way, no matter whether the top end 221 abuts against the electrical appliance body or the filter 200, the filter 200 and the electrical appliance body can be relatively far away and a gap can be formed to weaken the magnetic attraction between the filter 200 and the electrical appliance body, so that the filter 200 can be more conveniently and quickly removed from the electrical appliance body, which can improve the convenience and efficiency of removing the filter 200 relative to the electrical appliance body.

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

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

[0066] The abutment top 22 is connected to an end of the rotating part 21 away from the driving end 2311, that is, the driving end 2311 and the abutment top 22 are located on two sides of the rotating part 21 away from each other. The abutment top 22 also has an abutment top 221. When the driving end 2311 is driven, the rotating part 21 as a whole can rotate relative to the rotating shaft 10. At this time, the abutment top 22 and its abutment top 221 also rotate. According to the lever principle, the rotation direction of the abutment top 22 and its abutment top 221 is opposite to the rotation direction of the driving end 2311. In this way, by utilizing the lever principle, it will be more labor-saving to drive the abutment top 22 to rotate through the driving end 2311, and it will be more convenient for users to perform manual operation.

[0067] Furthermore, the abutting top portion 22 is arranged at an angle to the rotating portion 21 so that the abutting top portion 22 extends from the rotating portion 21 toward the electrical appliance body. In this way, in the rotation direction of the abutting top portion 22, the distance between the abutting top portion 221 and the electrical appliance body is closer, and the rotation stroke of the abutting top portion 221 from the initial position where it never abuts 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 to make the abutting top portion 221 abut against the electrical appliance body, thereby further improving the convenience and efficiency of the disassembly process of the filter 200.

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

[0069] The rotating plate 23 is in a plate shape so that the shaft hole plate 24 can be arranged on the rotating plate 23 . The rotating plate 23 has a driving end 2311 . By operating the driving end 2311 , 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 part 21. For example, 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 an shaft hole 24a for the rotating shaft 10 to pass therethrough. 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 6In some embodiments, in the connecting sub-plate 232, a surface facing away from the shaft hole plate 24 is provided with a second anti-slip protrusion 2321, that is, a lower surface of the connecting sub-plate 232 is provided with a second anti-slip protrusion 2321. In this way, the friction between the user's fingers and the second anti-slip protrusion 2321 can be increased, which is convenient for the user's fingers to drive the connecting sub-plate 232 upward. That is, the embodiment of the present application can also directly drive the connecting sub-plate 232 to rotate upward, so that the column follows the connecting sub-plate 232 to press upward against the electrical body, so that a gap is generated between the filter and the electrical body without the need to operate the driving sub-plate 231.

[0077] Therefore, similarly, a second anti-slip protrusion 2321 is provided on the lower surface of the connecting sub-plate 232. In this way, the friction between the user's fingers and the second anti-slip protrusion 2321 can be increased, making it easier for the user's fingers to rotate the driving sub-plate 231 upward, thereby reducing the risk of the user's fingers being separated from the lower surface of the connecting sub-plate 232. In particular, when the electrical device is a range hood, there may be oil stains on the lower surface of the connecting sub-plate 232, resulting in less friction between the lower surface of the connecting sub-plate 232 and the user's fingers. By providing the second anti-slip protrusion 2321, even if there is oil stains on the lower surface of the connecting sub-plate 232, the user's fingers are not easy to separate from the connecting sub-plate 232.

[0078] See also Figure 4 or Figure 6 In some embodiments, the quick-release structure 100 further includes a mounting member 30, on which the rotating shaft 10 is disposed, and the mounting member 30 is used to be fixedly connected to the filter 200, that is, the rotating shaft 10 is indirectly mounted on the filter 200 through the mounting member 30. In this way, on the one hand, the structure of the mounting member 30 can be flexibly arranged to facilitate the installation of the rotating shaft 10, and on the other hand, the interference of the filter 200 during the rotation of the rotating shaft 10 can also be avoided.

[0079] Please continue reading 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 housing, and has a mounting cavity 31a (see Figure 6 ), the rotating shaft 10 is mounted on the wall of the mounting cavity 31a, and the rotating member 20 is partially located in the mounting cavity 31a, specifically, the rotating plate 23 is mounted in the mounting cavity 31a. By providing the mounting cover 31, the rotating shaft 10 and the rotating plate 23 in the mounting cover 31 can be protected, and the influence of the oil smoke of the range hood on the rotating shaft 10 and the rotating plate 23 can be reduced. In addition, when the abutting top 22 (such as a column) rotates, it can extend out of the mounting cover 31 and the connecting cover 32 in sequence to abut against the electrical appliance body.

[0081] See also Figure 7-Figure 8The connecting cover 32 is connected to the mounting cover 31 and is used to clamp the filter 200 with the mounting cover 31 so that the mounting member 30 and the filter 200 are fixed. Specifically, the filter 200 has a mounting opening 200a. During the installation process of the mounting cover 31, the connecting cover 32 and the filter 200, the mounting cover 31 moves from bottom to top, and part of the mounting cover 31 passes through the mounting opening 200a. The other structures of the mounting cover 31 abut against the lower surface of the filter 200. After that, the connecting cover 32 is moved from top to bottom to abut 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 clamping the filter 200 between the connecting cover 32 and the mounting cover 31, the quick-release structure 100 and the filter 200 are conveniently and quickly installed.

[0082] Furthermore, the mouth wall of the installation opening 200a has at least one of the guide portion 3121 and the guide groove 200b, and the installation cover 31 has at least the other of the guide portion 3121 and the guide groove 200b, and the guide groove 200b is guided and matched with the guide portion 3121. In this way, in the process of the installation cover 31 moving from bottom to top to be installed on the filter 200, the guiding cooperation between the guide groove 200b and the guide portion 3121 can prevent the installation cover 31 from being installed upside down, thereby realizing the foolproof function, and on the other hand, the mutual guidance between the guide groove 200b and the guide portion 3121 can improve the transfer efficiency between the installation cover 31 and the filter 200.

[0083] See also 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 also includes a screw connection (not shown in the figure), which is passed 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 through the screw connection.

[0084] In a specific embodiment, the first mounting hole 311a and the second mounting hole 32a can both be through holes, and the screw connection 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 together 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 screw hole, the screw hole has an internal thread, and the screw-connector includes a screw, and the screw is screwed at least to 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 screw hole that cooperates with the screw. In this way, the screw is screwed to the first mounting hole 311a and the second mounting hole 32a at the same time, and the mounting cover 31 and the connecting cover 32 are connected more stably and more tightly.

[0086] Please continue reading Figure 4 In some embodiments, the mounting cover 31 has one of the positioning column 3111 and the positioning hole 32b, and the connecting cover 32 has the other of the positioning column 3111 and the positioning hole 32b. For example, the mounting cover 31 has the positioning column 3111, and the connecting cover 32 has the positioning hole 32b. The positioning column 3111 is positioned and matched with the positioning hole 32b. In this way, the positioning installation between the connecting cover 32 and the mounting cover 31 is achieved, so that the first mounting hole 311a and the second mounting hole 32a are aligned more quickly, which is convenient for the subsequent installation of the screw connection 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, and the abutting top 22 (column) passes through the first avoidance hole 312a and the second avoidance hole 32c when rotating to abut the electrical appliance body. That is, by providing the first avoidance hole 312a on the mounting cover 31 and 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 the electrical appliance body.

[0088] See also Figure 4 as well as 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 rotating plate 23 to move. The opening 312b is connected to the installation cavity 31a. The rotating part 21 can be installed in the installation cavity 31a through the opening 312b, and can also be rotated out of the installation cavity 31a through the opening 312b during the rotation process. The two ends of the rotating shaft 10 are respectively installed on the two opposite side walls of the surrounding shell 312. The first avoidance hole 312a is at least set in the surrounding shell 312. In order to avoid the top shell 311 from interfering with the top 22, the first avoidance hole 312a can also extend to the top shell 311.

[0090] See also 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.
