[0044] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0047] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0048] In addition, the terms "disposed", "connected", and "fixed" should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present disclosure can be understood according to specific circumstances.

[0049] Unless otherwise stated, the term "plurality" means two or more.

[0050] As can be seen from the background technology, the knob structure is a component of an electrical device and can be used to input instructions to the electrical device to control the operating state of the electrical device. For example, the push-pull knob of a range hood usually includes a mounting seat and a knob. The mounting seat is provided with a mounting slot, and the knob can be rotatably arranged in the mounting slot. The knob can be pressed or popped out. When the knob is pressed, the knob is embedded in the mounting seat as a whole, which is more beautiful and helps to reduce the adhesion of oil smoke on the surface of the knob; when the knob pops out, the user can input instructions through the knob to control the operating state of the range hood.

[0051] The inner wall of the mounting groove may be coated with lubricating grease to reduce the friction resistance encountered by the knob when it moves in the mounting seat, thereby ensuring that the knob can move smoothly in the mounting seat. In order to prevent the knob surface from being contaminated with lubricating grease, which affects the user experience, the outer diameter of the knob is usually set to be smaller than the inner diameter of the mounting groove, which will form a certain gap between the knob and the mounting seat, making it difficult for the side wall of the knob to contact the mounting seat.

[0052] Due to the gap between the knob and the mounting base, in actual applications, due to factors such as assembly errors, it is easy to cause the concentricity of the knob and the mounting base to be poor. Concentricity refers to whether the rotation center of the knob completely coincides with the center of the mounting slot when the knob is in the mounting slot. Once the concentricity deviates, that is, the knob is eccentric, it will not only cause poor rotation or jamming, affecting the user's operating experience, but may also cause unnecessary wear on the internal mechanical structure of the electrical equipment, thereby affecting the overall performance and life of the electrical equipment.

[0053] In order to solve the above problems, the embodiment of the present application provides a knob structure and an electrical device, wherein the knob structure includes a mounting seat and a knob; the mounting seat is provided with a mounting groove, and the inner wall of the mounting groove is provided with a limiter; the knob is provided with a guide structure, and the guide structure abuts against the surface of the limiter away from the inner wall of the mounting groove. By providing a guide structure on the knob, and the guide structure abuts against the limiter, the guide structure can be arranged in the gap between the knob and the mounting seat, reducing the matching clearance between the knob and the inner wall of the mounting groove, so that the knob and the mounting seat can remain concentric regardless of the first state or the second state, thereby improving the concentricity of the knob and the mounting seat.

[0054] The guide structure includes a first abutment joint; the knob is movably arranged in the mounting groove, and the first abutment joint is close to or away from the limiting member; when the knob is in the first state, the knob is located in the mounting groove, and the first abutment joint is spaced apart from the surface of the limiting member away from the notch of the mounting groove; when the knob is in the second state, at least part of the knob extends out of the notch of the mounting groove, and the first abutment joint abuts against the surface of the limiting member away from the notch of the mounting groove. By arranging the first abutment joint in the guide structure, the first abutment joint abuts against the limiting member in the second state, which can prevent the knob from excessively extending out of the mounting groove, thereby improving the stability of the knob structure in the second state.

[0055] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments may exist independently or in combination with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0056] Combination Figures 1 to 4 As shown, on the one hand, an embodiment of the present application provides a knob structure, including a mounting seat 100 and a knob 200; the mounting seat 100 is provided with a mounting groove 101, and a limiting member 110 is provided on the inner wall of the mounting groove 101; the knob 200 is provided with a guide structure 300, and the guide structure 300 abuts against the surface of the limiting member 110 away from the inner wall of the mounting groove 101; the guide structure 300 includes a first abutment head 311; the knob 200 is movably arranged in the mounting groove 101, and the first abutment head 311 is close to or away from the limiting member 110; when the knob 200 is in a first state, the knob 200 is located in the mounting groove 101, and the first abutment head 311 is spaced apart from the surface of the limiting member 110 away from the notch of the mounting groove 101; when the knob 200 is in a second state, at least a portion of the knob 200 extends out of the notch of the mounting groove 101, and the first abutment head 311 abuts against the surface of the limiting member 110 away from the notch of the mounting groove 101.

[0057] It can be understood that the mounting base 100 can usually be mounted on an electrical device to provide a mounting position for the knob 200. A switch shaft that can be connected to the knob 200 is usually provided inside the mounting base 100. By rotating the knob 200, the switch shaft can be controlled to rotate to drive the control member connected to the switch shaft to operate. Through this structure, the user can control the electrical device through the knob 200.

[0058] A limit member 110 is disposed on the inner wall of the mounting groove 101, and the limit member 110 is disposed protruding toward the inside of the mounting groove 101. The setting of the limit member 110 helps to limit the range of motion of the knob 200 in the mounting groove 101, and helps to ensure that the rotation center of the knob 200 is consistent with the center of the mounting groove 101, thereby improving concentricity.

[0059] A guide structure 300 is provided on the knob 200. The function of the guide structure 300 is to cooperate with the limit member 110. Through the abutment between the guide structure 300 and the limit member 110, the knob 200 can maintain a stable center position during movement and rotation, thereby improving the concentricity of the knob 200 and reducing the poor rotation or jamming caused by eccentricity.

[0060] When the knob 200 is in the first state, it is in the pressed state. At this time, the knob 200 is located in the mounting groove 101, and the knob 200 can abut against the surface of the stopper 110 facing the notch of the mounting groove 101. The knob 200 is embedded in the mounting seat 100 as a whole, so that the knob 200 remains beautiful when not in use and reduces the adhesion of external pollutants.

[0061] When the knob 200 is in the second state, it is in the pop-up state. At this time, at least part of the knob 200 extends out of the slot of the mounting slot 101, and the user can rotate the knob 200 to input instructions to the electrical device and control the operation of the electrical device. The abutment between the first abutment head 311 and the limiter 110 can prevent the knob 200 from excessively extending out of the mounting slot 101, thereby improving the stability of the knob structure in the second state.

[0062] As a part of the guide structure 300, the first abutment 311 can be close to or away from the stopper 110 when the knob 200 moves in the mounting slot 101. This arrangement allows the knob 200 to switch between the pressed and ejected states while maintaining effective contact with the stopper 110.

[0063] Specifically, by providing the guide structure 300 on the knob 200, the guide structure 300 abuts against the stopper 110, and the guide structure 300 can be provided in the gap between the knob 200 and the mounting seat 100, thereby reducing the matching clearance between the knob 200 and the inner wall of the mounting groove 101, so that the knob 200 and the mounting seat 100 can remain concentric regardless of the first state or the second state, thereby improving the concentricity of the knob 200 and the mounting seat 100. The knob 200 and the mounting seat 100 remain concentric, which can reduce the phenomenon of poor rotation or jamming of the knob 200, reduce the wear of the knob structure, and help improve the overall performance of the electrical equipment.

[0064] In some embodiments, the guide structure 300 can be extended and retracted along the depth direction of the mounting groove 101 .

[0065] The guide structure 300 is designed to be extendable and retractable along the depth direction of the installation groove 101. When the knob 200 is pressed, the guide structure 300 can be shortened so that the knob 200 is embedded in the installation groove 101; when the knob 200 is popped out, the guide structure 300 can be extended to ensure effective contact with the limit member 110.

[0066] Through the telescopic function, the guide structure 300 can always maintain contact with the limit member 110 at different positions of the knob 200, thereby improving the concentricity of the knob 200 and reducing the possibility of eccentricity of the knob 200.

[0067] Combination Figure 3 and Figure 4 As shown, in some embodiments, the guide structure 300 includes a first guide member 310 and a second guide member 320 that match each other; the second guide member 320 is sleeved on the outside of the knob 200; the first guide member 310 is located on the outside of the second guide member 320, and the first guide member 310 is provided with a first abutment head 311; in the process of the knob 200 being converted from the first state to the second state, the knob 200 is at least used to drive the second guide member 320 to move toward the slot of the installation slot 101, and the second guide member 320 is at least used to drive the first guide member 310 to move toward the slot of the installation slot 101.

[0068] The guide structure 300 is composed of two matching parts, namely a first guide member 310 and a second guide member 320. The first guide member 310 and the second guide member 320 are both rotating bodies, wherein the second guide member 320 is sleeved on the outside of the knob 200, and the first guide member 310 is located on the outside of the second guide member 320.

[0069] The guide structure 300 composed of the first guide member 310 and the second guide member 320 is connected to the peripheral side of the knob 200 and is located in the gap between the knob 200 and the mounting seat 100. The guide structure 300 can reduce the matching gap between the knob 200 and the inner wall of the mounting groove 101, provide support for the knob 200, provide a stable guide path for the knob 200, keep the knob 200 on a predetermined track during movement, and reduce the eccentricity and shaking of the knob 200.

[0070] When the knob 200 is converted from the first state to the second state, the knob 200 moves toward the outside of the slot of the mounting slot 101, and the knob 200 drives the second guide member 320 to move toward the slot of the mounting slot 101, and the second guide member 320 drives the first guide member 310 to move toward the slot of the mounting slot 101. This linkage mechanism ensures the coordinated movement between the knob 20 and the guide structure 300, avoiding the deviation and instability that may be caused by the independent movement of a single component. In addition, during the linkage process, the first guide member 310 and the second guide member 320 are always located in the gap between the knob 200 and the mounting seat 100, which can ensure that the knob 200 maintains good concentricity with the mounting slot 101 during the entire movement process.

[0071] When the knob 200 is switched from the second state to the first state, the knob 200 needs to be pressed toward the inside of the mounting groove 101. During the pressing process, the knob 200 drives the second guide member 320 to move away from the notch of the mounting groove 101 until the knob 200 abuts against the side of the first guide member 310 facing the notch of the mounting groove 101, and the knob 200 can continue to drive the first guide member 310 to move away from the notch of the mounting groove 101 until the knob 200 completely enters the mounting groove 101. During this process, the first guide member 310 and the second guide member 320 are also always located in the gap between the knob 200 and the mounting seat 100, which can prevent the knob 200 from deviating in a certain direction, thereby ensuring the stability of the knob 200 and the concentricity of the knob 200 and the mounting seat 100.

[0072] By designing the guide structure 300 to be composed of a first guide member 310 and a second guide member 320 that cooperate with each other, the operating force of the knob 200 can be better dispersed and carried, and the shaking and deviation of the knob 200 during operation can be reduced. The mutual cooperation of the first guide member 310 and the second guide member 320 can also more flexibly adapt to different operating states of the knob 200, provide a more accurate guide path, and effectively reduce the eccentricity of the knob 200.

[0073] In some embodiments, the first guide member 310 is provided with a first limiting portion 312, the first limiting portion 312 is located on the inner side of the first guide member 310, and the first limiting portion 312 is close to the slot of the installation groove 101 relative to the first abutment joint 311; the second guide member 320 is provided with a second abutment joint 321, and the second abutment joint 321 is used in conjunction with the first limiting portion 312; when the knob 200 is in the second state, the second abutment joint 321 abuts against the surface of the first limiting portion 312 away from the slot of the installation groove 101.

[0074] The first limiting portion 312 and the first abutment joint 311 are distributed at both ends of the first guide member 310 along the extension direction of the installation groove 101 , and the first limiting portion 312 is located on the inner side of the first guide member 310 , and the first abutment joint 311 is located on the outer side of the first guide member 310 .

[0075] It should be noted that the inner side of the first guide member 310 is the side of the first guide member 310 facing the installation groove 101 , and the outer side of the first guide member 310 is the side of the first guide member 310 away from the installation groove 101 .

[0076] The first limiting portion 312 provides a clear limiting position for the second guide member 320 , thereby ensuring that the second guide member 320 does not exceed a predetermined range during movement.

[0077] When the knob 200 is in the second state, i.e., the pop-up state, the first abutting head 311 of the first guide member 310 abuts against the surface of the limiting member 110 away from the notch of the installation slot 101, and the position of the first guide member 310 along the axial direction of the mounting seat 100 is fixed. The second abutting head 321 abuts against the surface of the first limiting portion 312 of the first guide member 310 away from the notch of the installation slot 101, and the first limiting portion 312 can limit the second guide member 320 from continuing to move toward the notch of the installation slot 101, so that the position of the second guide member 320 along the axial direction of the mounting seat 100 is also stable, and the knob 200 remains stable in the pop-up state.

[0078] In some embodiments, when the knob 200 is transformed from the first state to the second state, the second abutment head 321 abuts against the inner side of the first guide member 310 , and the second abutment head 321 is close to the first limiting portion 312 .

[0079] When the knob 200 is converted from the first state to the second state, the knob 200 moves toward the outside of the slot of the mounting groove 101, and the knob 200 drives the second guide member 320 to move toward the slot of the mounting groove 101. The second abutment head 321 of the second guide member 320 abuts against the inner side of the first guide member 310, and the gap between the first guide member 310 and the second guide member 320 is small, which can ensure the concentric effect of the first guide member 310 and the second guide member 320, and further ensure the concentricity of the knob 200 and the mounting seat 100.

[0080] The second abutment joint 321 of the second guide member 320 is close to the first limiting portion 312. When the second abutment joint 321 abuts against the surface of the first limiting portion 312 away from the notch of the installation groove 101, it can drive the first guide member 310 to move toward the notch of the installation groove 101, thereby realizing the linkage between the first guide member 310 and the second guide member 320.

[0081] In some embodiments, the second guide member 320 is provided with a second limiting portion 322, which is located on the inner side of the second guide member 320; the knob 200 is provided with a mounting member 210, which is located on the side of the second limiting portion 322 away from the slot of the mounting slot 101, and the mounting member 210 abuts against the second limiting portion 322.

[0082] The second limiting portion 322 and the second abutment joint 321 are distributed at both ends of the second guide member 320 along the extension direction of the installation groove 101 , and the second limiting portion 322 is located on the inner side of the second guide member 320 , and the second abutment joint 321 is located on the outer side of the second guide member 320 .

[0083] It should be noted that the inner side of the second guide member 320 is the side of the second guide member 320 facing the installation groove 101 , and the outer side of the second guide member 320 is the side of the second guide member 320 away from the installation groove 101 .

[0084] Exemplarily, the mounting member 210 may be a plurality of hooks disposed on the knob 200. The plurality of hooks are spaced apart along the circumference of the knob 200. The hook has a hook head extending toward the second limiting member 110, the hook head is located at a side of the second limiting portion 322 away from the notch of the mounting groove 101, and the hook head abuts against a surface of the second limiting portion 322 away from the notch of the mounting groove 101.

[0085] When the knob 200 is converted from the first state to the second state, the knob 200 moves toward the outside of the slot of the installation slot 101, and the mounting member 210 of the knob 200 abuts against the second limiting portion 322, which can drive the second guide member 320 to move toward the slot of the installation slot 101, and further drive the first guide member 310 to move toward the slot of the installation slot 101, thereby realizing the linkage between the knob 200 and the guide structure 300. During the linkage process, the guide structure 300 is located on the peripheral side of the knob 200, which can reduce the matching clearance between the knob 200 and the inner wall of the installation slot 101, and provide support for the knob 200, provide a stable guide path for the knob 200, so that the knob 200 remains on a predetermined track during movement, and reduces the eccentricity and shaking of the knob 200.

[0086] Combination Figure 6 As shown, in some embodiments, the second guide member 320 is provided with a fixing portion 323 ; the fixing portion 323 is fixedly connected to the second guide member 320 , and the surface of the fixing portion 323 facing the notch of the installation groove 101 abuts against the installation member 210 .

[0087] For example, the fixing portion 323 may be a groove formed on the inner wall of the second guide member 320. The groove is adapted to the mounting member 210, and the mounting member 210 may be snapped into the groove. The side of the mounting member 210 that is away from the notch of the mounting groove 101 abuts against the bottom surface of the groove, so that when the knob 200 is pressed, the knob 200 may drive the second guide member 320 to move away from the notch of the mounting groove 101.

[0088] The side surface of the mounting member 210 close to the notch of the mounting groove 101 abuts against the top surface of the groove. In this way, when the knob 200 pops out, the knob 200 can drive the second guide member 320 to move toward the notch of the mounting groove 101.

[0089] The two ends of the mounting slot 101 are connected to the outside. One end of the mounting seat 100 is used to be arranged outside the electrical device so that the knob 200 is exposed to the outside for user operation. The other end of the mounting seat 100 is used to be arranged inside the electrical device.

[0090] When installing the knob structure, the first guide member 310 and the second guide member 320 can be sequentially installed from one end of the installation slot 101 toward the inner side of the electrical device, and then the knob 200 can be installed into the second guide member 320 from one end of the installation slot 101 away from the inner side of the electrical device.

[0091] The mounting member 210 may be a hook with a certain degree of deformation. When the mounting member 210 is connected to the second guide member 320, the hook may be squeezed to shrink inwards to enter the interior of the second guide member 320. When the hook moves to a position corresponding to the fixing portion 323, the deformation may be restored and the fixing portion 323 may be engaged.

[0092] Combination Figure 3 and Figure 4 As shown, in other embodiments, the knob 200 may be provided with a support member 500, the support member 500 is located on the inner side of the mounting member 210, and the side wall of the support member 500 abuts against the mounting member 210. The support member 500 can support the mounting member 210, so that the mounting member 210 is closely abutted against the inner wall of the second guide member 320, so that when the knob 200 is pressed, a large friction resistance can be formed between the knob 200 and the second guide member 320, so that the knob 200 can drive the second guide member 320 to move away from the notch of the mounting groove 101.

[0093] When installing the knob structure, the first guide member 310 and the second guide member 320 can be sequentially installed from one end of the installation slot 101 toward the inner side of the electrical device, and then the knob 200 can be installed into the second guide member 320 from one end of the installation slot 101 away from the inner side of the electrical device.

[0094] The mounting member 210 may be a plurality of hooks with a certain deformation capability, and the plurality of hooks are distributed at intervals along the circumference of the knob 200. When the mounting member 210 is connected to the second guide member 320, the hooks may be squeezed to shrink inwardly so as to enter the interior of the second guide member 320. When the hook head of the hook passes the position where the second limit portion 322 is located, the deformation may be restored. Finally, the support member 500 is installed from one end of the mounting groove 101 toward the inner side of the electrical equipment, so that the support member 500 is supported on the inner side of the mounting member 210, so that the mounting member 210 abuts against the second guide member 320.

[0095] The outer diameter of the support member 500 may be slightly larger than the diameter of the cylindrical cavity enclosed by the mounting member 210 , so that when the support member 500 is supported on the inner side of the mounting member 210 , the mounting member 210 can be closely abutted against the second guide member 320 .

[0096] Combination Figure 5 As shown, in some embodiments, the limit member 110 is provided with a plurality of balls 120, and the plurality of balls 120 are arranged at intervals along the circumference of the limit member 110; at least part of the balls 120 extend out of the surface of the limit member 110 away from the inner wall of the mounting groove 101, and the guide structure 300 is connected to the portion of the surface where the balls 120 extend out of the limit member 110.

[0097] It should be noted that the maximum length of the ball 120 extending out of the stopper 110 is smaller than the radius of the ball.

[0098] The ball 120 can form effective contact with the guide structure 300 , reduce direct friction between the guide structure 300 and the limiter 110 , reduce wear of the guide structure 300 , and improve the smoothness of relative movement between the guide structure 300 and the limiter 110 .

[0099] The balls 120 are arranged at intervals along the circumference of the limiting member 110 to ensure that the circumference of the guide structure 300 is evenly stressed when the guide structure 300 moves, thereby improving the stability of the guide structure 300 and reducing the possibility of eccentricity and shaking of the knob 200.

[0100] Specifically, when the knob 200 switches between the first state and the second state, the guide structure 300 moves along the axial direction of the mounting groove 101. By arranging the ball 120 on the stopper 110, the ball 120 and the guide structure 300 are in point contact, which can reduce the friction force of the relative movement between the guide structure 300 and the stopper 110, and improve the smoothness of the switch of the knob 200 between the first state and the second state.

[0101] When the user rotates the knob 200, the guide structure 300 rotates axially around the mounting groove 101. By setting the ball 120 on the limit member 110, the ball 120 makes point contact with the guide structure 300, which can reduce the friction of the relative movement between the guide structure 300 and the limit member 110 and improve the smoothness of rotating the knob 200.

[0102] Combination Figure 3 and Figure 4 As shown, in some embodiments, the knob structure further includes a reset member 400 , which abuts against the knob 200 ; the reset member 400 is at least used to apply a pushing force to the knob 200 extending out of the notch of the installation slot 101 .

[0103] It can be understood that the reset member 400 can drive the knob 200 to switch from the first state to the second state, thereby improving the user's operational convenience.

[0104] The reset member 400 directly abuts against the knob 200, which reduces the complexity of the reset mechanism and ensures that the reset member 400 can directly transmit the driving force to the knob 200, thereby providing an effective reset effect.

[0105] Specifically, the reset member 400 can keep the knob 200 in the first state. When the knob 200 does not need to be operated, the knob 200 is pressed so that the knob 200 enters the installation slot 101. In this state, the reset member 400 is locked and will not drive the knob 200 to extend out of the installation slot 101.

[0106] When the knob 200 needs to be operated, the knob 200 is pressed again. At this time, the reset member 400 can be unlocked and a pushing force is applied to the knob 200 to extend out of the notch of the installation slot 101 so that the knob 200 pops out of the installation slot 101.

[0107] Exemplarily, the reset member 400 may be a spring self-locking and releasing mechanism. The spring self-locking and releasing mechanism can switch between two states, one is a state in which the spring is compressed and locked, and the other is a state in which the spring is released and rebounds.

[0108] When the user presses the knob 200 to a certain stroke, the locking structure inside the spring self-locking and release mechanism will lock the spring to keep it in the current compressed state. This locking structure can be locked by a ratchet, a buckle or a slider. In the state where the spring is locked, even if the external force pressing the knob 200 disappears, the spring will not rebound, and the knob 200 can be kept in the installation slot 101.

[0109] When the user presses the knob 200 again, the locking effect of the locking structure will be released, and the spring will rebound quickly, driving the knob 200 to pop out of the installation slot 101.

[0110] Among them, the spring self-locking and releasing mechanism can be any existing structure that can achieve the above functions, and the embodiments of the present application do not impose any restrictions on this.

[0111] Another aspect of an embodiment of the present application provides an electrical device, comprising the knob structure provided by any of the above embodiments.

[0112] It should be noted that electrical equipment may include kitchen appliances such as ovens, steamers or gas stoves; it may also include environmental conditioning appliances such as air conditioners, humidifiers or dehumidifiers; it may also include cleaning appliances such as washing machines and dryers; it may also include entertainment appliances such as televisions, audio equipment or gaming equipment; it may also include other household or commercial appliances such as electric water heaters and water dispensers.

[0113] Combination Figure 1 As shown, the electrical device has an operation panel 10 , and a bracket 20 is arranged on the side of the operation panel 10 facing the interior of the electrical device. The bracket 20 may be provided with a connected rotary switch and a switch shaft.

[0114] The mounting base 100 of the knob structure can be installed on the bracket 20, and the end of the mounting base 100 away from the bracket 20 is inserted into the operation panel 10 and extends to the side of the operation panel 10 away from the bracket 20, and the mounting groove 101 of the mounting base 100 faces the outside of the electrical equipment.

[0115] The switch shaft is located in the mounting base 100, and the knob 200 is connected to the switch shaft. By rotating the knob 200, the rotary switch can be controlled through the switch shaft to input instructions to the electrical device and control the operating status of the electrical device.
