Description

Technical Field

[0001] This utility model relates to the field of stove technology, and in particular to a human detection device, an anti-dry burning control component, and a stove for stoves. Background Technology

[0002] When cooking with a stove, if the user is not nearby and the stove is in unattended use, situations such as dry-burning or overflowing pots cannot be addressed promptly. Therefore, users typically need to remain near the stove while cooking to monitor its operation and promptly shut it off in case of issues like dry-burning or overflowing pots, thus preventing dangerous situations.

[0003] However, this prevents users from leaving the stove when other situations arise while cooking, resulting in poor flexibility in stove use and affecting the user experience. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defect in the prior art that users cannot leave the stove when cooking, resulting in poor flexibility in the use of the stove. The present invention provides a human detection device, an anti-dry burning control component, and a stove for stoves.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] In a first aspect, this utility model provides a human detection device for a stove, which includes a radar module and a mounting bracket. The radar module includes a radar PCB board and a communication connector. One end of the communication connector is electrically connected to the radar PCB board, and the other end of the communication connector is used to electrically connect to the control module of the stove. The radar PCB board is provided with a radar antenna and a radar processor. The radar PCB board is mounted on the mounting bracket, and the mounting bracket is provided with a pre-positioning component and a connector. The mounting bracket is used for pre-positioning relative to the control PCB board of the control module through the pre-positioning component, and for connecting relative to the control PCB board through the connector.

[0007] This utility model provides a human detection device for stoves, comprising a radar module and a mounting bracket. The radar module includes a radar PCB board and a communication connector. The radar PCB board has a radar antenna and a radar processor. The communication connector enables electrical connection between the radar PCB board and the stove's control module. Furthermore, a pre-positioning component on the mounting bracket allows for pre-positioning of the mounting bracket relative to the control PCB board of the control module, facilitating convenient and quick installation of the radar module. The mounting bracket also includes a connector for connecting the mounting bracket and the control PCB board, ensuring the radar module's position relative to the control module's control PCB board. With the control module fixed and reliable, the human detection device provided in this embodiment of the invention can sense and monitor human presence near the stove through a radar antenna. This allows it to identify whether there is someone near the stove and send the presence status to the control module, enabling the control module to take over the stove and ensure its normal operation. This ensures the stove can still be used normally even when the user leaves the vicinity, thus improving the user experience. At the same time, the radar module ensures the reliability of the connection between the radar module and the control module, avoiding signal instability and ensuring the stability of the human detection device.

[0008] Preferably, the communication connector includes a power strip and a plurality of connection pins, all of which are disposed on the power strip; the radar PCB has a plurality of first sockets, one end of each connection pin is disposed in a corresponding first socket and soldered to the radar PCB, so that the communication connector and the radar PCB together form the radar module.

[0009] This configuration not only integrates all the connector pins through the connector board, facilitating docking with the radar PCB board, but also ensures the reliability of the connection and signal transmission between the connector pins and the radar PCB board through corresponding insertion and soldering with the first socket.

[0010] Preferably, the mounting bracket includes a bracket base and two lateral limiting members, which are respectively disposed on both sides of the bracket base; each of the two lateral limiting members has a limiting groove on its adjacent side, and the two sides of the radar PCB board are respectively located in the limiting grooves formed by the two lateral limiting members.

[0011] This configuration allows the two sides of the radar PCB board to be fixed relative to the bracket base, thus ensuring that the radar PCB board is fixed in the lateral direction relative to the mounting bracket. At the same time, the two sides of the radar PCB board are located in the limiting grooves formed by the two lateral limiting members, which also restricts the radar PCB board from being fixed in the direction perpendicular to the placement surface relative to the bracket base. Therefore, the lateral limiting members are used to fix the radar PCB board as a whole, ensuring the structural stability of the human detection device.

[0012] Preferably, a clearance groove is formed on the front side of the bracket base, the clearance groove being recessed from the front surface of the bracket base into the interior of the bracket base; when the mounting bracket and the control PCB board are connected, at least a portion of the connector's plug plate is located within the clearance groove and abuts against the groove wall. This arrangement achieves both limiting the movement of the communication connector and limiting the movement of the radar module as a whole.

[0013] Secondly, this utility model provides an anti-dry-burning control component for a stove, which includes the human detection device for the stove as described above; the anti-dry-burning control component also includes a control module, the control module includes a control PCB board and a controller, the controller is disposed on the control PCB board, and the other end of the communication connector is electrically connected to the control PCB board.

[0014] The anti-dry-burning control component described in this utility model has the same beneficial effects as the aforementioned human sensory detection device, and will not be repeated here.

[0015] Preferably, a positioning hole is formed on the control PCB board, and the pre-positioning member is a positioning post. The positioning post extends from the bottom of the mounting bracket in a direction away from the mounting bracket, and the positioning post can be inserted into the positioning hole on the control PCB board to pre-position the mounting bracket relative to the control PCB board. The positioning post extends in a direction perpendicular to the bottom surface of the mounting bracket, and when the mounting bracket is pre-positioned relative to the control PCB board, the bottom surface of the mounting bracket is in contact with the surface of the control PCB board.

[0016] This setup allows for easy and quick installation of the human detection device by simply inserting the positioning pin into the positioning hole on the control PCB board.

[0017] Preferably, the connector is provided with an elastic buckle, the control PCB board has a locking hole, and the mounting bracket and the control PCB board are connected to each other by the elastic buckle being engaged in the locking hole.

[0018] This design not only makes the connection more convenient and faster, but also enables a detachable connection between the mounting bracket and the control PCB board. This allows for easy disassembly when the human detection device malfunctions or needs to be replaced, which not only facilitates maintenance but also reduces maintenance costs.

[0019] Preferably, the communication connector includes a power strip and a plurality of connection pins, all of which are disposed on the power strip; the control PCB has a plurality of second sockets, and the other end of each connection pin is disposed in a corresponding second socket and soldered to the control PCB to ensure the stability of the connection between the communication connector and the control PCB and the signal transmission.

[0020] Thirdly, this utility model provides a stove that includes the anti-dry-burning control component as described above.

[0021] The stove described in this utility model has the same beneficial effects as the aforementioned human detection device and anti-dry burning control group, and will not be repeated here.

[0022] Preferably, the stove includes a control device, the control device includes a housing, the interior of the housing forms a receiving cavity, and the anti-dry-burning control component is located in the receiving cavity; the housing has a clearance opening at the top position corresponding to the anti-dry-burning control component, and the radar module can be exposed from the clearance opening.

[0023] This design facilitates the installation of anti-dry-burning control components and prevents structural interference. It also benefits radar antenna signal transmission and reception, preventing signal interference, obstruction, or misinterpretation. For example, the clearance opening is specifically located on the top cover.

[0037] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0038] Example 1

[0039] like Figure 1-7 As shown, this embodiment of the invention provides a human detection device 10 for a stove, which includes a radar module 1 and a mounting bracket 2. The radar module 1 includes a radar PCB board 11 and a communication connector 412. One end of the communication connector 412 is electrically connected to the radar PCB board 11, and the other end is used for electrical connection to the stove's control module. Furthermore, the radar PCB board 11 is equipped with a radar antenna and a radar processor.

[0040] Specifically, the radar controller can be fixed to the radar PCB board 11 by soldering or surface mounting technology, and signal transmission between the radar antenna and the radar controller can be achieved through the traces designed on the radar PCB board 11. The communication connector 412 is electrically connected to the control module of the stove, specifically to the control PCB board 20 of the control module, thus realizing the electrical connection between the radar PCB board 11 and the control PCB board 20.

[0041] For example, at least a portion of the communication connector 412 may be made of metal, such as copper or aluminum, to enable signals emitted by the radar processor to be transmitted to the control module. When the radar antenna is mounted on the radar PCB board 11, the required antenna structure and orientation can be formed on the PCB surface using a PCB etching process.

[0042] Furthermore, the radar PCB board 11 is mounted on the mounting bracket 2, which is provided with a pre-positioning component 3 and a connecting component 4. The mounting bracket 2 is used to pre-position relative to the control PCB board 20 via the pre-positioning component 3, and the mounting bracket 2 is used to connect relative to the control PCB board 20 via the connecting component 4.

[0043] The radar PCB board 11 is used to connect to the control PCB board 20 of the control module via the mounting bracket 2. In this way, the radar PCB board 11 can be fixed on the control PCB board 20, which not only secures the human detection device 10, but also facilitates the electrical connection between the radar PCB board 11 and the control PCB board 20.

[0044] In practical implementation, the radar antenna on the radar PCB board 11 is electrically connected to the radar processor. The radar antenna is used to transmit radio frequency signals and receive echo signals reflected from the target. The radar processor executes algorithms based on the echo signals received by the radar antenna to obtain information such as distance, speed, or angle. Furthermore, the communication connector 412 enables an electrical connection between the radar PCB board 11 and the control PCB board 20. Therefore, the information obtained by the radar processor can be transmitted to the controller on the control PCB board 20, enabling the controller to perform corresponding operations such as timing and cookware temperature monitoring.

[0045] For example, radar module 1 can be configured to be woken up periodically to collect human signals, and then send the collected data to the radar processor of radar module 1. The radar processor uses further built-in algorithms to determine whether there is a person in the area. Based on this, if the stove detects the disappearance of a person through radar module 1 during use, it will continuously monitor for a set time, and after the set time has elapsed, it will send control commands to the gas valve, igniter, or power switch of the induction cooker, ultimately achieving functions such as adjusting the flame or automatically shutting off the flame. Conversely, if the stove detects the continuous presence of a person through radar module 1 during use, radar module 1 can enter a sleep state to reduce power consumption. Specifically, how radar module 1 transmits and receives signals, and how the radar processor and controller implement the corresponding program response design, are existing technologies and will not be elaborated here.

[0046] In summary, the human detection device 10 for stoves provided by this utility model includes a radar module 1 and a mounting bracket 2. The radar module 1 includes a radar PCB board 11 and a communication connector 412. The radar PCB board 11 is equipped with a radar antenna and a radar processor. The communication connector 412 enables the radar PCB board 11 to be electrically connected to the control module of the stove. Furthermore, the pre-positioning component 3 on the mounting bracket 2 enables the pre-positioning of the mounting bracket 2 relative to the control PCB board 20 of the control module, thus facilitating the quick and easy installation of the radar module 1. The mounting bracket 2 also includes a connector 4, which is used to establish communication between the mounting bracket 2 and the control PCB board 20. The radar module 1 is connected to the control module to ensure its fixed and reliable position. Thus, the human detection device 10 provided in this embodiment can sense and monitor the human body near the stove via the radar antenna, thereby identifying whether there is a person near the stove. This information is then sent to the control module, allowing the control module to take over control of the stove and ensure its normal operation. This ensures the stove can still be used normally even when the user leaves the vicinity, thus improving the user experience. Simultaneously, the radar module 1 ensures reliable connection with the control module, avoiding signal instability and guaranteeing the stability of the human detection device 10.

[0047] It should be noted that the "PCB board" mentioned above specifically refers to a Printed Circuit Board, which is a substrate used to support and connect electronic components. In this embodiment, the radar PCB board 11 serves as a substrate for mounting the radar antenna and radar processor, and is used for installing the corresponding components and realizing their functions.

[0048] like Figure 4 and Figure 6As shown, in some embodiments, the communication connector 412 includes a connector plate 121 and a plurality of connector pins 122. All connector pins 122 are inserted through the connector plate 121. Based on this, the radar PCB board 11 has a plurality of first sockets. One end of each connector pin 122 is inserted into a corresponding first socket 111 and soldered to the radar PCB board 11, so that the communication connector 412 and the radar PCB board 11 together form the radar module 1. This arrangement not only integrates all connector pins 122 through the connector plate 121, facilitating docking with the radar PCB board 11, but also ensures the reliability of the connection and signal transmission between the connector pins 122 and the radar PCB board 11 through the corresponding insertion and soldering connection with the first sockets 111.

[0049] In practice, the connecting pin 122 is electrically connected to the radar processor on the radar PCB board 11 to transmit the instructions output by the radar processor to the control module of the stove for program response. When the connecting pin 122 is soldered to the radar PCB board 11, one end of the connecting pin 122 is first passed through the first socket 111 on the radar PCB board 11, and then the connecting pin 122 is soldered to the radar PCB board 11 at the position of the first socket 111, so that the two are physically and electrically connected.

[0050] In addition, when installing the human detection device 10, the radar PCB board 11 can be soldered and fixed to the connecting pin 122 to form the radar module 1 as a whole, and then the radar module 1 as a whole can be installed on the mounting bracket 2 as a component.

[0051] Regarding the fixation of the control PCB board 20 relative to the mounting bracket 2, in some embodiments, the mounting bracket 2 specifically includes a bracket base 21 and two lateral limiting members 22. The two lateral limiting members 22 are respectively disposed on both sides of the bracket base 21, and a limiting groove 23 is formed on the side of the two lateral limiting members 22 that are close to each other. The two side parts of the radar PCB board 11 are respectively located in the limiting grooves 23 formed by the two lateral limiting members 22.

[0052] By setting the lateral limiting members 22 on both sides of the bracket base 21, the two sides of the radar PCB board 11 can be limited and fixed relative to the bracket base 21, thereby ensuring that the radar PCB board 11 is fixed in the lateral direction relative to the mounting bracket 2. At the same time, the two sides of the radar PCB board 11 are located in the limiting grooves 23 formed by the two lateral limiting members 22, which can also limit the radar PCB board 11 in the direction perpendicular to the placement surface relative to the bracket base 21. Therefore, the setting of the lateral limiting members 22 realizes the overall limiting and fixing of the radar PCB board 11, ensuring the structural stability of the human detection device 10.

[0053] In a specific implementation, the lateral limiting member 22 can be configured to extend from the outer edge of the mounting base toward the top of the mounting base, so as to form a limiting groove 23 together with the edge portion of the upper surface of the mounting base. In this way, the radar PCB board 11 can be placed directly on the upper surface of the mounting base, and the two side edges are respectively located in the limiting grooves 23 formed by the two lateral limiting members 22.

[0054] In addition, the outer edge of the radar PCB board 11 can be made to abut against the side wall of the limiting groove 23 opposite to the groove opening, thereby further ensuring the limiting effect achieved by the radar PCB board 11 through the limiting groove 23.

[0055] In addition to limiting the radar PCB board 11 to a certain extent through the lateral limiting member 22, it is also necessary to limit the communication connector 412 to a certain degree. Therefore, in some embodiments, a relief groove 211 is formed on the front side of the bracket base 21, which is recessed from the front surface of the bracket base 21 into the interior of the bracket base 21. Furthermore, when the mounting bracket 2 and the control PCB board 20 are connected, at least a portion of the connector plate 121 of the communication connector 412 is located within the relief groove 211 and abuts against the groove wall of the relief groove 211.

[0056] For details, please refer to Figure 4 As shown, when installing the radar PCB board 11, the radar PCB board 11 can be inserted into the limiting groove 23 along one side opening of the limiting groove 23. When inserted into the limiting groove 23 and moved along the extension direction of the limiting groove 23, during the movement, part of the communication connector 412 enters into the clearance groove 211 until the plug plate 121 of the communication connector 412 abuts against the side wall of the clearance groove 211 opposite to the opening, thereby preventing the radar PCB board 11 and the communication connector 412 from continuing to move. At this time, not only is the communication connector 412 limited, but the radar module 1 as a whole is also limited.

[0057] It should be noted that when the radar PCB board 11 is placed, the side with the radar antenna facing upwards, which facilitates the radar antenna transmitting and receiving signals towards the outside of the structure. Furthermore, the vertical direction of the radar PCB board 11 mentioned above refers to the top of the radar PCB board 11 being above it, and the bottom of the radar PCB board 11 being below it.

[0058] In addition to the aforementioned human detection device 10, this utility model embodiment also provides an anti-dry-burning control component for a stove, which includes the aforementioned human detection device 10 and a control module.

[0059] Specifically, the control module includes a control PCB board 20 and a controller. The controller is mounted on the control PCB board 20, and the other end of the communication connector 412 is electrically connected to the control PCB board 20. Alternatively, the controller can be fixed to the control PCB board 20 using soldering or surface mount technology.

[0060] Based on the above, in order to achieve electrical connection between the radar PCB board 11 and the control PCB board 20 via the communication connector 412, in some embodiments, the control PCB board 20 is provided with several second sockets, and the other end of each connecting pin 122 passes through a corresponding second socket and is soldered to the control PCB board 20. This arrangement ensures reliable structural connection between the communication connector 412 and the control PCB board 20, and also ensures reliable electrical connection.

[0061] Regarding how the mounting bracket 2 achieves pre-positioning with the control PCB board 20 via the pre-positioning element 3, in some embodiments, positioning holes are formed on the control PCB board 20. The pre-positioning element 3 is specifically a positioning post, which extends from the bottom of the mounting bracket 2 in a direction away from the mounting bracket 2. The positioning post can be inserted into the positioning hole on the control PCB board 20 to pre-position the mounting bracket 2 relative to the control PCB board 20. With this configuration, positioning can be achieved simply by inserting the positioning post into the positioning hole on the control PCB board 20 when installing the human detection device 10, making installation more convenient and faster.

[0062] Based on this, the positioning post can be configured to extend along a direction perpendicular to the bottom surface of the mounting bracket 2, and the bottom surface of the mounting bracket 2 is in contact with the surface of the control PCB board 20 when the mounting bracket 2 is pre-positioned relative to the control PCB board 20. This ensures that after the mounting bracket 2 and the control PCB board 20 are pre-positioned, the structure of the mounting bracket 2 relative to the control PCB board 20 is stable and will not move relative to the control PCB board 20.

[0063] For example, the number of positioning posts can be set to multiple, and the multiple positioning posts can be arranged at intervals along the horizontal or vertical direction of the mounting bracket 2. The positioning holes are set one-to-one with the multiple positioning posts to further improve the positioning effect.

[0064] When the mounting bracket 2 is connected to the control PCB board 20 through the connector 4 of the mounting bracket 2, in some embodiments, an elastic buckle 41 can be provided on the connector 4, and a locking hole can be opened on the control PCB board 20. The mounting bracket 2 and the control PCB board 20 are connected to each other by the elastic buckle 41 locking into the locking hole.

[0065] This setup not only makes the connection more convenient and faster, but also enables a detachable connection between the mounting bracket 2 and the control PCB board 20. This makes it easy to disassemble the human detection device 10 when it malfunctions or needs to be replaced, which not only facilitates maintenance but also reduces maintenance costs.

[0066] For details, please refer to Figure 4 As shown, the number of connectors 4 can be set to two, with the two connectors 4 located on both sides of the bracket base 21, and each connector 4 is provided with an elastic buckle 41.

[0067] For example, the bracket base 21 and the two connectors 4 can be integrally molded, and the connectors 4 and the elastic buckles 41 disposed thereon can be integrally molded to reduce the complexity of structural assembly and avoid installation deviations.

[0068] Specifically, during the engagement of the mounting bracket 2 and the control PCB board 20, as the positioning post is inserted into the positioning hole, the position of the elastic buckle 41 on the connector 4 moves towards the hole. Furthermore, the elastic buckle 41 deforms as the connector 4 passes through the hole, allowing the end of the connector 4 to pass smoothly through the hole. Once the elastic buckle 41 has completely passed through the hole, it returns to its original shape, abutting against the other side of the hole, thus achieving engagement between the mounting bracket 2 and the control PCB board 20.

[0069] Furthermore, with the elastic buckle 41 engaged in the buckle hole, the bottom surface of the mounting bracket 2 can abut against the upper surface of the control PCB board 20. This further ensures that the mounting bracket 2 is installed stably and reliably relative to the control PCB board 20, thus ensuring the stability of the radar module 1 during use and guaranteeing detection accuracy.

[0070] Based on the above, after the radar module 1 is connected and fixed to the control PCB board 20 through the mounting bracket 2, the radar PCB board 11 needs to be structurally configured relative to the control PCB board 20.

[0071] Specifically, in some embodiments, the plane where the radar PCB board 11 is located intersects with the plane where the control PCB board 20 is located, forming a first angle of 45°. This arrangement enables the radar PCB board 11 to have a better spatial detection range, allowing the signal to radiate spherically from the radar antenna, thereby improving the radar's signal transmission and reception performance.

[0072] Based on the above, the communication connector 412 can be configured with two connector plates 121, with all connection pins 122 passing through the two connector plates 121. Furthermore, one connector plate 121 is used to abut against the surface of the radar PCB board 11, while the other connector plate 121 is used to abut against the surface of the control PCB board 20, thereby further ensuring that the position of the communication connector 412 relative to the control PCB board 20 and the radar PCB board 11 is fixed.

[0073] To accommodate the tilted arrangement of the radar PCB board 11 relative to the control PCB board 20, the connecting pin 122 can be designed in two sections, with one section for connecting to the radar PCB board 11 and the other section for connecting to the control PCB board 20. In this way, the two sections of the connecting pin 122 form a 135° angle, so that they can be inserted and fixed onto the radar PCB board 11 and the control PCB board 20 respectively.

[0074] like Figure 3 As shown, in some embodiments, the control PCB board 20 is also provided with a software programming interface 30, which can be connected to the controller for programming or modifying the control program.

[0075] Furthermore, by setting a software programming interface 30 on the control PCB board 20, it is convenient to update or upgrade the software later, and to upgrade the software by directly connecting the programming tool pin to the software programming interface 30, thereby achieving rapid iterative upgrades of the software without disassembling the top cover 1013.

[0076] Furthermore, such as Figures 1-3 As shown, the control PCB board 20 is also equipped with an indicator light 40, which is used to realize corresponding reminder functions. For example, the indicator light 40 is electrically connected to the anti-dry-burning control component, so as to indicate whether the human detection function is turned on or running.

[0077] For example, the indicator light 40 can be displayed as a green light or a red light, and the light has corresponding sticker text attached to it. When the light is off, no text effect can be seen on the whole machine. When the light is on, the text and text color of the corresponding light group can be seen, which can be used to indicate the status of the pot or the food in the pot during the cooking process.

[0078] In addition, other types of indicator lights 40 can be installed on the control PCB board 20, such as those simultaneously displaying reminders for human detection protection, dry burning protection, and healthy oil temperature, thereby improving the flexibility and user experience of the stove. Specifically, how each indicator light 40 connects to its corresponding module to achieve illumination is existing technology and will not be elaborated upon here.

[0079] Example 2

[0080] This utility model provides a stove, which includes a human detection device 10 as described in Embodiment 1 and an anti-dry burning control component including the human detection device 10.

[0081] The stove provided in this embodiment of the utility model includes a radar module 1 and a mounting bracket 2 via a human detection device 10. The radar module 1 includes a radar PCB board 11 and a communication connector 412. The radar PCB board 11 is equipped with a radar antenna and a radar processor. The communication connector 412 enables the radar PCB board 11 to be electrically connected to the control module of the stove. Furthermore, a pre-positioning component 3 on the mounting bracket 2 enables the mounting bracket 2 to be pre-positioned relative to the control PCB board 20 of the control module, thereby facilitating the quick and easy installation of the radar module 1. The mounting bracket 2 also includes a connector 4 for connecting the mounting bracket 2 and the control PCB board 20. The radar module 1 is connected to the control module to ensure its fixed and reliable position. Thus, the human detection device 10 provided in this embodiment can sense and monitor the human body near the stove through the radar antenna, thereby identifying whether there is a person near the stove. The status of whether someone is near the stove is then sent to the control module, allowing the control module to take over the stove and ensure it maintains normal operation. This ensures the stove can still be used normally even when the user leaves the vicinity, thus improving the user experience. Simultaneously, the radar module 1 ensures reliable connection with the control module, avoiding signal instability and guaranteeing the stability of the human detection device 10.

[0082] like Figures 1-2 As shown, the stove provided in this embodiment of the present invention also includes a control device 100, which includes a housing 101. Further, a receiving cavity is formed inside the housing 101, and the anti-dry-burning control component is located within the receiving cavity.

[0083] Based on this, the outer casing 101 of the control device 100 specifically includes a casing body 1012 and a top cover 1013, wherein the top cover 1013 is detachably connected to the opening of the casing body 1012. When installing the anti-dry-burning control component inside the control device 100, the control PCB board 20 can be mounted on the casing body 1012. The entire control device 100 can be installed on the inside of the glass panel of the stove by adhesive curing.

[0084] like Figure 2As shown, a recessed platform 1015 can be provided on the bonding surface of the upper cover 1013 of the control device 100. During adhesive curing, hot melt adhesive can be applied directly to the recessed platform 1015, which enables rapid curing of the adhesive. Compared with the traditional method of providing initial adhesion by pasting adhesive strips and then applying adhesive for curing, the method of applying adhesive for curing at the recessed platform 1015 provided by this utility model embodiment reduces the curing time cycle of the adhesive, improves production turnover, and reduces adhesive costs.

[0085] In practice, the recessed platform 1015 can be set to one or more, and the shape of the recessed platform 1015 can be set to a circle or a square according to the requirements.

[0086] like Figure 1 and Figure 2 As shown, in some embodiments, the control PCB board 20 of the control module is fixed to the accommodating cavity of the housing 101 by at least one of fastener connection or snap-fit. Based on the above, a clearance opening 1011 is provided at the top position of the corresponding anti-dry-burning control component of the housing 101, through which the radar module 1 can be exposed.

[0087] This design facilitates the installation of anti-dry-burning control components and prevents structural interference. It also benefits the signal transmission and reception of the radar antenna, preventing signal interference, obstruction, or misinterpretation. For example, the clearance opening 1011 is specifically located on the upper cover 1013.

[0088] When the anti-dry-burning control component is equipped with an indicator light 40, a display window 1014 is provided on the upper cover 1013 of the control device 100 at the position corresponding to each indicator light 40, so that the light of the indicator light 40 on the control PCB board 20 can be transmitted.

[0089] Since the glass panel connected to the control device 100 is light-transmitting, in order to ensure that the light from the indicator lights 40 can be emitted well, and to avoid light interference between adjacent indicator lights 40 when multiple indicator lights 40 are set, in some embodiments, a separation bar 103 can be set in the gap between each display window 1014 to separate the light generated by adjacent indicator lights 40.

[0090] In practice, the separation bar 103 can be located on the side of the upper cover 1013 facing the glass panel.

[0091] Correspondingly, to further improve the light-blocking effect, in some embodiments, a first flange 104 may be provided on the side of the upper cover 1013 facing away from the glass panel, and the first flange 104 surrounds the edge of each display window 1014, as detailed in the following figures. Figure 7As shown. By setting the first flange 104 structure, after the top cover 1013 is installed in place, the first flange 104 can effectively surround the indicator light 40 on the control PCB board 20, thereby further preventing the indicator light 40 from overflowing.

[0092] like Figures 1-3 As shown, in some embodiments, the control PCB board 20 of the control module is provided with multiple buttons 50. The buttons 50 are used to input operation signals to start and end the timing, or to input operation signals to set the timing time.

[0093] Furthermore, each button 50 includes a conductive sheet 501 and a return spring 502. The conductive sheet 501 is mounted on the control PCB board 20 via the return spring 502. Correspondingly, multiple mounting slots are provided on the upper cover 1013 of the control device 100, and the buttons 50 pass through the mounting slots. The return spring 502 extends out of the mounting slot, and the conductive sheet 501 is located on the outside of the upper cover 1013.

[0094] When a user presses the area of ​​the glass panel corresponding to the conductive sheet 501 with their finger, the pressure is transmitted through the panel to the conductive sheet 501, compressing the return spring 502 and electrically connecting the conductive sheet 501 to the control PCB board 20. When the user releases their finger, the return spring 502 undergoes elastic deformation under the action of elastic potential energy, causing the conductive sheet 501 to move to its initial position and adhere to the panel, thereby improving the reliability of operation.

[0095] like Figure 7 As shown, for example, the upper cover 1013 is provided with a second flange at the position corresponding to each mounting groove, and the second flange surrounds the edge of the mounting groove. By providing the second flange structure, the deformation of the return spring 502 can be guided, ensuring that the return spring 502 will not be skewed when it deforms under the action of pressing.

[0096] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
