Description

Technical Field

[0001] The present application relates to the field of household electrical appliances, and in particular, to a heating device. Background Art

[0002] The maximum allowable power of electrical appliances set for electrical appliance safety is different in different areas. Therefore, in order for the maximum allowable power of the same multi-burner stove or other heating equipment to be suitable for the requirements of different areas, in the relevant scheme, multiple power modes are generally set on the multi-burner stove and other heating equipment, and the maximum allowable power limited by different power modes is different. At the same time, a method for switching power modes is provided on multi-burner stoves and other heating equipment. After the multi-burner stove and other heating equipment is installed in the household, the power mode of the product can be adjusted according to the local electrical appliance safety management regulations to limit the maximum allowable power of the product to the permitted range. However, in the relevant scheme, the power mode is generally switched by the combination of multiple buttons on the control panel. The specific operation flow chart is as follows. Fig.13 As shown, this switching method, on the one hand, requires the user to carefully study the product manual, resulting in a poor user experience. On the other hand, this method requires the operation of multiple combination keys, so the operation is very cumbersome and it is very easy to make an operational error that leads to a failure in power mode switching.

[0003] Therefore, how to design a power mode switching method for heating equipment that is easy to operate, simple, and not prone to operating errors has become a problem that needs to be solved urgently. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0005] Therefore, one object of the present invention is to provide a heating device.

[0006] To achieve the above-mentioned purpose, the technical solution of the first aspect of the utility model provides a heating device including: a stove; an adjustment switch installed on the stove; a detection device connected to the adjustment switch and used to detect the position of the adjustment switch; and a control device connected to the detection device and used to adjust the allowable power range of the stove according to the detection result of the detection device.

[0007] According to the utility model, a heating device is provided, including a stove, an adjustment switch, a detection device and a control device. The stove can realize a normal heating function. The stove has different allowable power ranges. The adjustment switch is used for users to operate to adjust the actual allowable power range of the stove. The detection device is used to detect the position of the switch, so as to determine the state of the switch. The control device is used to adjust the current allowable power range of the stove according to the result of the detection of the detection device. With this setting, the user can adjust the allowable power range of the stove according to actual needs, so that the same stove can be applied to the electrical safety management requirements of different regions, so that there is no need to design products with different allowable power ranges for different regions, thereby improving the application range of the product. In addition, with this setting, since different positions of an adjustment switch correspond to different allowable power ranges, the user only needs to adjust the adjustment switch to different positions to achieve the switching of different powers, so that the user's operation is relatively simple, and no complicated operation process is required, thereby reducing the error rate and improving the user experience.

[0008] In addition, the heating device in the above technical solution provided by the utility model may also have the following additional technical features:

[0009] In a possible design, the heating device further includes: a control panel arranged on the first area of ​​the stove; and an adjustment switch arranged on the second area of ​​the stove.

[0010] In this technical solution, the heating device also includes a control panel. The normal operation control of the heating device can be realized through the control panel. The control panel is arranged on the first area, and the adjustment switch is arranged on the second area of ​​the stove, that is, the control panel and the adjustment switch are arranged in different positions, so that the user is not easy to touch the adjustment switch during the normal use of the heating device, so that the user can avoid the user from accidentally triggering the power switch during the normal use of the heating device such as the multi-burner stove, for example, when the user is operating other functions, thereby reducing the probability of accidentally touching the power mode.

[0011] In a possible design, the stove includes multiple power modes, each power mode corresponds to a defined allowable power range; the control device is used to adjust the power mode of the stove according to the detection result of the detection device to adjust the allowable power range of the stove.

[0012] In this technical solution, the stove has different power modes. In different power modes, the allowable power range of the stove is different. Therefore, when in use, the heating device can be adjusted to an appropriate power mode according to the area where the heating device is used. In this way, the allowable power range of the heating device can be limited to prevent the working power of the heating device from exceeding the maximum power limit allowed in the local area.

[0013] In one possible design, the detection device includes: a detection terminal; an adjustment switch including two connection terminals, one of the two connection terminals is grounded, and the other of the two connection terminals is connected to the detection terminal; a voltage detection device, used to detect the voltage at the detection terminal; and a control device is used to adjust the allowable power range of the stove according to the voltage signal detected by the voltage detection device.

[0014] In this technical solution, one end of the regulating switch is connected to the detection terminal, and the other end is grounded, so that the grounding control of the detection terminal can be achieved by closing the regulating switch, thereby changing the voltage at the detection terminal. For example, when the switch is closed, the detection terminal is grounded through the regulating switch, and the voltage at the detection terminal is zero. At this time, the voltage detection device can output a low-level signal. Conversely, when the switch is disconnected, the detection terminal is not grounded, and the voltage at the detection terminal is high voltage. At this time, the voltage detection device can output a high-level signal. The control device can adjust the allowable power range of the stove to a value that matches the current position of the regulating switch according to the signal output by the voltage detection device.

[0015] In one possible design, the stove includes a first power mode and a second power mode; when the detection device detects that the adjustment switch is in the open position, the control device controls the stove to operate in the first power mode, and when the detection device detects that the adjustment switch is in the closed position, the control device controls the stove to operate in the second power mode, and the upper limit value of the allowable power range defined by the first power mode is greater than the upper limit value of the allowable power range defined by the second power mode.

[0016] In this technical solution, the stove includes a first power mode and a second power mode. In the first power mode, the allowable power range, that is, the upper limit value of the allowable power range is greater than the allowable power range in the first power mode. Therefore, the first power mode is a high power mode, and the second power mode is a low power mode. The regulating switch includes two positions: on and off. When the regulating switch is closed, the detection terminal is grounded, and the stove works in a low power mode. When the regulating switch is disconnected, the detection terminal is not grounded, and the stove works in a high power mode. The regulating switch is in an open state (i.e., a disconnected state) by default. That is, in the default state, the stove works in a high power mode. In the actual process, the default state of the regulating switch and the default working mode of the stove can be set according to the actual situation of the heating equipment.

[0017] In one possible design, the detection device includes a sensing element, such as a light sensor, an electromagnetic induction device, etc. Such a device can generate different electrical signals according to the position of the adjustment switch, so that the position of the adjustment switch can be determined by the different electrical signals.

[0018] In a possible design, the adjustment switch includes at least one of a toggle switch, a slide switch, or a push switch.

[0019] In a possible design, the regulating switch is a mechanical switch, because a mechanical switch is more durable, safer, and does not require electricity, so it has a longer service life and is not easy to be damaged. Of course, the regulating switch can also be an electronic switch.

[0020] In a possible design, the heating device further includes: a cover plate, which is installed on the stove and forms an installation cavity with the stove, and the cover plate can move relative to the stove to open or close the installation cavity; and the regulating switch is installed in the installation cavity.

[0021] In this technical solution, a cover plate is provided on the stove, and the cover plate can be opened and closed. The regulating switch is installed in the installation cavity formed by the stove and the cover plate. The cover plate can prevent the user from accidentally touching the regulating switch, and can also protect the regulating switch from being damaged by dust, liquid, etc.

[0022] In one possible design, a mounting groove is provided on the stove, and the adjustment switch is installed in the mounting groove, and the adjustment switch is lower than the notch of the mounting groove. An elastic clip is provided on the adjustment switch, and the elastic clip can be snapped into the mounting groove to limit the adjustment switch in the mounting groove.

[0023] In this technical solution, by providing a mounting groove, the regulating switch can be embedded and installed inside the stove, so as to avoid the regulating switch protruding from the surface of the stove, thereby improving the aesthetics of the stove. The regulating switch is provided with an elastic buckle, which can limit the regulating switch in the mounting groove, so that the positioning installation of the regulating switch on the stove can be simply and conveniently achieved.

[0024] Furthermore, a cover plate is provided on the stove, and the cover plate can be opened and closed. The mounting slot can be opened and closed by the cover plate. The regulating switch is installed in the mounting cavity formed by the stove and the cover plate. The cover plate can prevent the user from accidentally touching the regulating switch, and can also protect the regulating switch by the cover plate to prevent the regulating switch from being damaged by dust, liquid, etc.

[0025] In one possible design, the adjustment switch is set on the bottom or back of the heating device. This setting can set the adjustment switch on an uncommon surface of the product, so that the user can avoid accidentally touching the adjustment switch during use of the product, thereby reducing the probability of the user accidentally triggering the power mode switch. Secondly, this setting can also prevent the adjustment switch from being exposed on the front of the product, thereby improving the overall aesthetics of the product.

[0026] In one possible design, a mounting groove is provided on the stove, a first positioning structure is provided on the inner wall of the mounting groove, and a second positioning structure adapted to the first positioning structure is provided on the adjusting switch. Through the cooperation of the first positioning structure and the second positioning structure, the installation angle of the adjusting switch when installed in the mounting groove can be limited.

[0027] In this technical solution, the first positioning structure and the second positioning structure form a fool-proof structure, that is, the adjustment switch can only be correctly installed when the first positioning structure and the second positioning structure are aligned, that is, if the first positioning structure and the second positioning structure are not aligned, the adjustment switch cannot be correctly installed, thus limiting the installation angle of the adjustment switch. Since the present application adjusts the allowable power range of the stove by adjusting the position of the switch, whether the adjustment switch is correctly installed will affect the allowable power range of the stove. In the present application, the fool-proof structure formed by the first positioning structure and the second positioning structure can reduce the probability of incorrect installation of the adjustment switch and ensure the accuracy of the power mode switching of the stove.

[0028] Exemplarily, one of the first positioning structure and the second positioning structure is a protrusion, and the other of the first positioning structure and the second positioning structure is a groove.

[0029] In a possible design, the heating device further includes: an indicator light, installed on the stove, and used to indicate the allowable power range of the current setting of the stove.

[0030] In this technical solution, the current allowable power range of the stove can be understood through the feedback of the indicator light, so that the user can easily grasp the actual working status of the stove at any time.

[0031] In the above technical solution, the number of the indicator lights is one or more, and the control device is connected to the one or more indicator lights, and can control the operation of the one or more indicator lights according to the current allowable power range of the stove.

[0032] In this technical solution, the stove is generally provided with multiple allowable power ranges, and a corresponding indicator light can be set for each allowable power range. After the current allowable power range of the stove is adjusted, the corresponding indicator light can be turned on according to the actual allowable power range of the stove, while the other indicator lights can be turned off. In this way, the current allowable power range of the stove can be understood through multiple indicator lights, thereby making it convenient for users to understand the current status of the stove.

[0033] In addition, when the allowable power range of the stove is displayed by an indicator light, two allowable power ranges can be displayed by turning one indicator light on and off in two states. For example, when the stove has only two allowable power ranges, only one indicator light can be provided.

[0034] Exemplarily, the indicator light includes a first indicator light and a second indicator light. The adjustment switch includes two positions. When the adjustment switch is in the first position, the control device sets the allowable power range of the stove to the first power, the first indicator light is on, and the second indicator light is off. When the adjustment switch is in the second position, the control device sets the allowable power range of the stove to the second power, the first indicator light is off, and the second indicator light is on.

DETAILED DESCRIPTION

[0052] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0053] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0054] like Figure 1 and Figure 2 As shown, an embodiment of the first aspect of the utility model provides a heating device including a stove 1, an adjustment switch 2, a detection device 3 and a control device 4.

[0055] Among them, the stove 1 is the main unit of the device, which can realize the basic heating function. Figure 3 and Figure 4 As shown, the regulating switch 2 is installed on the stove 1. Figure 2 As shown, the detection device 3 is connected to the regulating switch 2 for detecting the position of the regulating switch 2. The control device 4 is connected to the detection device 3 for adjusting the allowable power range of the stove 1 according to the detection result of the detection device 3.

[0056] According to the utility model, a heating device is provided, comprising a stove 1, an adjustment switch 2, a detection device 3 and a control device 4. The stove 1 can realize a normal heating function. The stove 1 has different allowable power ranges. The adjustment switch 2 is used for the user to operate to adjust the actual allowable power range of the stove 1. The detection device 3 is used to detect the position of the switch, so as to determine the state of the switch. The control device 4 is used to adjust the current allowable power range of the stove 1 according to the result of the detection of the detection device 3. With this setting, the user can adjust the allowable power range of the stove 1 according to actual needs, so that the same stove 1 can be applied to the electrical safety management requirements of different regions, so that there is no need to design products with different allowable power ranges for different regions, thereby improving the applicable scope of the product. In addition, with this setting, since different positions of an adjustment switch 2 correspond to different allowable power ranges, the user only needs to adjust the adjustment switch 2 to different positions to achieve the switching of different powers, so that the user's operation is relatively simple, and no complicated operation process is required, thereby reducing the error rate and improving the user experience.

[0057] In one possible design, Figure 5 As shown, the heating device further comprises a control panel 5. The control panel 5 is arranged on the first area 12 of the stove 1. Figure 2 As shown, the regulating switch 2 is arranged on the second area 14 of the oven 1 .

[0058] In this embodiment, the heating device further includes a control panel 5. Conventional operation control of the heating device can be achieved through the control panel 5. The control panel 5 is arranged on the first area 12, and the adjustment switch 2 is arranged on the second area 14 of the stove 1, that is, the control panel 5 and the heating device are arranged at different positions, so that the user is not easy to touch the adjustment switch 2 during normal use of the heating device, so that the user can avoid the user from accidentally triggering the power switch during normal use of the heating device such as a multi-burner stove, for example, when the user is operating other functions, thereby reducing the probability of accidentally touching the power mode.

[0059] In a possible design, the stove 1 includes multiple power modes, each power mode corresponds to a limited allowable power range; the control device 4 is used to adjust the power mode of the stove 1 according to the detection result of the detection device 3 to adjust the allowable power range of the stove 1.

[0060] In this embodiment, the stove 1 has different power modes. In different power modes, the allowable power range of the stove 1 is different. Therefore, when in use, the heating device can be adjusted to an appropriate power mode according to the area where the heating device is used. In this way, the allowable power range of the heating device can be limited to prevent the working power of the heating device from exceeding the maximum power limit allowed in the local area.

[0061] In one possible design, Figure 1 and Figure 2 As shown, the detection device 3 includes: a detection terminal 32; the regulating switch 2 includes two first connection terminals 22 and a second connection terminal 24, the first connection terminal 22 is grounded, and the second connection terminal 24 is connected to the detection terminal 32; a voltage detection device 34, used to detect the voltage at the detection terminal 32; the control device 4 is used to adjust the allowable power range of the stove 1 according to the voltage signal detected by the voltage detection device 34.

[0062] In this embodiment, one end of the regulating switch 2 is connected to the detection terminal 32, and the other end is grounded, so that the grounding control of the detection terminal 32 can be achieved by closing the regulating switch 2, so that the voltage at the detection terminal 32 can be changed. For example, when the switch is closed, the detection terminal 32 is grounded through the regulating switch 2, and the voltage at the detection terminal 32 is zero. At this time, the voltage detection device 34 can output a low-level signal. On the contrary, when the switch is disconnected, the detection terminal 32 is not grounded, and the voltage at the detection terminal 32 is high voltage. At this time, the voltage detection device 34 can output a high-level signal. The control device 4 can adjust the allowable power range of the stove 1 to a value matching the current position of the regulating switch 2 according to the signal output by the voltage detection device 34.

[0063] In one possible design, the stove 1 includes a first power mode and a second power mode; when the detection device 3 detects that the adjustment switch 2 is in the disconnected position, the control device 4 controls the stove 1 to operate in the first power mode, and when the detection device 3 detects that the adjustment switch 2 is in the closed position, the control device 4 controls the stove 1 to operate in the second power mode, and the upper limit value of the allowable power range defined by the first power mode is greater than the upper limit value of the allowable power range defined by the second power mode.

[0064] In this embodiment, the stove 1 includes a first power mode and a second power mode. In the first power mode, the power range is allowed, that is, the upper limit of the power range is greater than the power range allowed in the first power mode. Therefore, the first power mode is a high power mode, and the second power mode is a low power mode. The regulating switch 2 includes two positions, open and closed. When the regulating switch 2 is closed, the detection terminal 32 is grounded, and the stove 1 works in a low power mode. When the regulating switch 2 is disconnected, the detection terminal 32 is not grounded, and the stove 1 works in a high power mode. The regulating switch 2 is in an open state (i.e., a disconnected state) by default. That is, in the default state, the stove 1 works in a high power mode. In the actual process, the default state of the regulating switch 2 and the default working mode of the stove 1 can be set according to the actual situation of the heating device.

[0065] In a possible design, the detection device 3 includes sensing components, such as light sensing, electromagnetic sensing and other devices, which can generate different electrical signals according to the position of the adjustment switch 2, so that the position of the adjustment switch 2 can be determined by different electrical signals.

[0066] In one possible design, Figures 4 to 12 As shown, the regulating switch 2 is a mechanical switch. Because the mechanical switch is more durable, safer, and does not require electricity, its service life is longer and it is not easy to be damaged. Of course, the regulating switch 2 can also be an electronic switch.

[0067] In one possible design, Figure 8 and Fig. 9 As shown, the heating device also includes: a cover plate 6, which is installed on the stove 1 and forms an installation cavity with the stove 1 (i.e., the area enclosed by the cover plate 6 and the stove 1), and the cover plate 6 can move relative to the stove 1 to open or close the installation cavity; the adjustment switch 2 is installed in the installation cavity.

[0068] In this embodiment, a cover plate 6 is provided on the stove 1, and the cover plate 6 can be opened and closed. The regulating switch 2 is installed in the installation cavity formed by the stove 1 and the cover plate 6. The cover plate 6 can prevent the user from accidentally touching the regulating switch 2, and can also protect the regulating switch 2 by the cover plate 6 to prevent the regulating switch 2 from being damaged by contact with dust, liquid, etc.

[0069] In one possible design, Fig.11 and Figure 3 As shown, a mounting groove 16 is provided on the stove 1, and the regulating switch 2 is installed in the mounting groove 16, and the regulating switch 2 is lower than the notch of the mounting groove 16. An elastic buckle is provided on the regulating switch 2, and the elastic buckle can be snapped into the mounting groove 16 to limit the regulating switch 2 in the mounting groove 16.

[0070] In this embodiment, the adjusting switch 2 can be embedded and installed inside the stove 1 by providing the installation groove 16, so as to avoid the adjusting switch 2 protruding from the surface of the stove 1, thereby improving the aesthetics of the stove 1. The adjusting switch 2 is provided with an elastic buckle, which can limit the adjusting switch 2 in the installation groove 16, so that the positioning installation of the adjusting switch 2 on the stove 1 can be simply and conveniently achieved.

[0071] Furthermore, if Figure 8 and Fig. 9As shown, the stove 1 is provided with a cover plate 6, and the cover plate 6 can be opened and closed. The mounting groove 16 can be opened and closed by the cover plate 6. The regulating switch 2 is mounted in the mounting cavity formed by the stove 1 and the cover plate 6. The cover plate 6 can prevent the user from accidentally touching the regulating switch 2, and can also protect the regulating switch 2 by the cover plate 6 to prevent the regulating switch 2 from being damaged by contact with dust, liquid, etc.

[0072] In a possible design, the adjustment switch 2 is arranged on the bottom or back of the heating device. With this arrangement, the adjustment switch 2 can be arranged on an uncommon surface of the product, so that the user can avoid accidentally touching the adjustment switch 2 during use of the product, thereby reducing the probability of the user accidentally triggering the power mode switch. Secondly, this arrangement can also prevent the adjustment switch 2 from being exposed on the front of the product, thereby improving the overall aesthetics of the product.

[0073] In one possible design, Figure 6 As shown, the stove 1 is provided with a mounting groove 16, the inner wall of the mounting groove 16 is provided with a first positioning structure 18, and the regulating switch 2 is provided with a second positioning structure 26 adapted to the first positioning structure 18. Through the cooperation of the first positioning structure 18 and the second positioning structure 26, the installation angle of the regulating switch 2 when installed in the mounting groove 16 can be limited.

[0074] In this embodiment, the first positioning structure 18 and the second positioning structure 26 form a foolproof structure, that is, the regulating switch 2 can be correctly installed only when the first positioning structure 18 and the second positioning structure 26 are aligned, that is, if the first positioning structure 18 and the second positioning structure 26 are not aligned, the regulating switch 2 cannot be correctly installed, thus limiting the installation angle of the regulating switch 2. Since the present application adjusts the allowable power range of the stove 1 by adjusting the position of the switch 2, whether the regulating switch 2 is correctly installed will affect the allowable power range of the stove 1. In the present application, the foolproof structure formed by the first positioning structure 18 and the second positioning structure 26 can reduce the probability of incorrect installation of the regulating switch 2, thereby ensuring the accuracy of the power mode switching of the stove 1.

[0075] For example, Figure 6 As shown, one of the first positioning structure 18 and the second positioning structure 26 is a protrusion, and the other of the first positioning structure 18 and the second positioning structure 26 is a groove.

[0076] In one possible design, Figure 2 As shown, the heating device further includes: an indicator light, which is installed on the stove 1 and is used to indicate the allowable power range of the current setting of the stove 1.

[0077] In this embodiment, the current allowable power range of the stove 1 can be understood through the feedback of the indicator light, so that the user can easily grasp the actual working status of the stove 1 at any time.

[0078] In the above embodiment, the number of the indicator lights is one or more, and the control device 4 is connected to the one or more indicator lights, and can control the operation of the one or more indicator lights according to the current allowable power range of the stove 1.

[0079] In this embodiment, the stove 1 is generally provided with a plurality of allowable power ranges, and a corresponding indicator light may be provided for each allowable power range. After the current allowable power range of the stove 1 is adjusted, the corresponding indicator light may be turned on according to the actual allowable power range of the stove 1, while the other indicator lights may be turned off. In this way, the current allowable power range of the stove 1 may be known through the plurality of indicator lights, thereby facilitating the user to understand the current state of the stove 1.

[0080] In addition, when the allowable power range of the stove 1 is displayed by the indicator light, two allowable power ranges can be displayed by switching one indicator light on and off. For example, when the stove 1 has only two allowable power ranges, only one indicator light can be provided.

[0081] For example, Figure 2 As shown, the indicator lights include a first indicator light 7 and a second indicator light 8. The regulating switch 2 includes two positions. When the regulating switch 2 is in the first position, the control device 4 sets the allowable power range of the stove 1 to the first power, the first indicator light 7 is turned on, and the second indicator light 8 is turned off. When the regulating switch 2 is in the second position, the control device 4 sets the allowable power range of the stove 1 to the second power, the first indicator light 7 is turned off, and the second indicator light 8 is turned on.

[0082] The regulating switch 2 includes a pressing switch.

[0083] The regulating switch 2 comprises a sliding switch. Figure 3 , Figure 7 and Fig. 9 The schematic diagram shows that the adjustment switch 2 is a slide switch.

[0084] The regulating switch 2 includes a toggle switch. Fig.10 , Fig.11 and Fig.12 The schematic diagram shows that the regulating switch 2 is a toggle switch.

[0085] The heating device further includes a heating module 9 connected to the control device 4. The control device 4 can control the maximum allowable power of the heating module 9 according to the power mode. At the same time, the control device 4 can also control the actual operating power of the heating module 9 during operation, but the actual operating power should be less than the maximum allowable power.

[0086] The following uses a multi-burner stove as an example to further introduce the heating device in this application.

[0087] Among them, whole-machine power switching usually occurs in some household appliances. Users want to switch different power limits for the same appliance in different usage environments to limit the whole-machine power limit of the appliance.

[0088] For example, in a multi-burner stove, there are currently two main solutions for implementing power switching. The first is to directly replace the display panel software and use the software to limit the power of the entire machine. The second is to switch different power modes by operating a combination of buttons. The flow chart of switching power by using a combination of buttons is as follows Fig.13 These two switching methods have the following disadvantages: 1. Replacing the display panel software involves two models, and power switching cannot be achieved on the same model. 2. Fig.13 It can be seen that switching power through key combination operation requires multiple operations by the user, and the process is complicated. If the customer does not read the instructions, he will not be able to operate at all. In addition, in this way, the user may accidentally trigger the power switch when operating other functions.

[0089] Based on the above problems, this embodiment proposes the following improvement scheme:

[0090] like Figures 1 to 12 As shown, the solution is to install a mechanical switch (i.e., adjustment switch 2) at the bottom of the appliance. When the switch is turned to one side, the whole appliance is in low power mode, and the corresponding low power indicator light appears. When the switch is turned to the other side, the whole appliance is in high power mode, and the corresponding high power indicator light appears. A box cover (i.e., equivalent to cover plate 6) is added to the mechanical switch to prevent accidental touch.

[0091] This solution opens a recessed mounting hole in the base and installs a mechanical switch into the mounting hole. The elastic buckle of the mechanical switch will be stuck into the inner side of the base, so that it cannot be loosened. The mechanical switch includes two gears (open or closed). The two pins of the mechanical switch are respectively connected to a pin of the main control chip of the display board and GND (ground). The switch is in the open state by default. At this time, the pin is not connected to the ground. The chip scan detects that the pin is at a high level. The default power output is high power, and the high-power indicator light corresponding to the display area appears. When the mechanical switch is closed, the chip pin is pulled low, and the chip scan detects the change in the pin state, and sends a command to the main control board to switch the output power to low power. The low-power indicator light corresponding to the display area appears. Mechanized power switching is realized.

[0092] This solution can quickly switch the upper limit of the power of the whole machine. And the power switching can be realized by directly turning on the mechanical switch. And this solution installs the mechanical switch in the recessed mounting hole on the back of the base. The switch is lower than the bottom surface of the base, and a box cover is added on the upper side of the mechanical switch to avoid the switch being triggered by mistake.
