[0038] The present application will be further described by way of examples, but the present application is not limited in the scope of the examples.

[0039] When food is cooked by the stove, if the user is not near the stove, that is, the stove is in a use state without monitoring, if conditions such as dry burning of the pot or pot overflow occur, the user cannot handle it in time. Therefore, when cooking, the user usually needs to stay near the stove to monitor the use state of the stove and turn off the stove in time when conditions such as dry burning of the pot or pot overflow occur to avoid dangerous situations.

[0040] However, this will make the user unable to leave the stove position when cooking if other situations need to be handled, resulting in poor flexibility of the stove use and affecting the user's use experience.

[0041] In view of the above situation, the embodiments of the present application provide a control assembly with human sensing detection function and a stove comprising the same, so as to detect whether there is a person near the stove and realize targeted control of the stove in the absence of a person, thereby improving the user's use experience.

[0042] The above is the core concept of the present invention. The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0043] Example 1

[0044] like Figures 1-7 As shown, an embodiment of the present invention provides a control component with a human sensing detection function, which includes a control module, a radar module 2, and a communication connector 3. The control module includes a control PCB board 1 and a controller, wherein the controller is disposed on the control PCB board 1. The radar module 2 includes a radar PCB board 21 and a mounting bracket 22. The radar PCB board 21 is provided with a radar antenna and a radar processor. The radar PCB board 21 is disposed on the mounting bracket 22, and the mounting bracket 22 is detachably connected to the control PCB board 1. On this basis, the communication connector 3 includes a plurality of connecting pins 31, the two ends of which are respectively connected to the control PCB board 1 and the radar PCB board 21, so that the radar PCB board 21 and the control PCB board 1 are electrically connected through the connecting pins 31.

[0045] Specifically, the controller can be secured to the control PCB 1 using soldering or surface mount technology. Correspondingly, the radar processor can also be mounted on the radar PCB 21 using the same technology. When the radar PCB 21 is connected to the control PCB 1 via the mounting bracket 22, the mounting bracket 22 serves only to secure the radar PCB 21 to the control PCB 1. The mounting bracket 22 does not electrically connect the radar PCB 21 to the control PCB 1. Therefore, the mounting bracket 22 can, for example, be made of an insulating material, such as insulating plastic.

[0046] On this basis, the electrical connection between the radar PCB 21 and the control PCB 1 is achieved through the communication connector 3. Specifically, the ends of the connecting pins 31 are connected to the control PCB 1 and the radar PCB 21 respectively. For example, holes are drilled in both the control PCB 1 and the radar PCB 21, and the ends of the connecting pins 31 are inserted into the holes. The connecting pins are then soldered to the PCBs at the drilled holes. In this way, the radar PCB 21 and the control PCB 1 are electrically connected via the connecting pins 31.

[0047] It should be noted that the "PCB board" mentioned above specifically refers to a Printed Circuit Board, i.e., a printed circuit board, which is a substrate for supporting and connecting electronic components. In the present embodiment, the control PCB board 1 and the radar PCB board 21 both serve as substrates for the control module and the radar module 2, for mounting corresponding components and realizing functions.

[0048] In a specific implementation, the radar antenna on the radar PCB board 21 is electrically connected to the radar processor, wherein the radar antenna is used to transmit radio frequency signals and receive echo signals reflected from a target. The radar processor is used to execute algorithms based on the echo signals received by the radar antenna to obtain distance, speed, or angle information. Further, the connection pin 31 realizes electrical connection between the radar PCB board 21 and the control PCB board 1, so that the information obtained by the radar processor can be transmitted to the controller on the control PCB board 1, enabling the controller to perform timing, cookware temperature monitoring, and other operations.

[0049] For example, the radar module 2 can be configured to be awakened once every certain period of time to collect human body signals, and then send the collected data to the radar processor of the radar module 2, which determines whether there is a person in the area through further built-in algorithms. On this basis, if the personnel disappear during the use of the stove is detected by the radar module 2, continuous monitoring within a set time is performed, and after the set time is exceeded, a control command is sent to the gas valve, igniter, or power switch of the induction cooker, etc. of the stove to execute the mechanism, ultimately realizing the functions of adjusting the firepower or automatic extinguishing. Correspondingly, if the personnel continuously exist during the use of the stove is detected by the radar module 2, the radar module 2 can enter a sleep state to reduce power consumption. Specifically, how the radar module 2 above specifically implements signal transmission and reception, and how the radar processor and the controller specifically implement corresponding program response design are all prior art, and will not be described here.

[0050] As can be seen, by setting the radar module 2 and associating the radar module 2 with the control module, real-time human sensing detection near the stove can be realized, so that the stove can implement a "sentinel mode" during use, i.e., when the user is located near the stove and uses the stove normally, the radar module 2 remains in a sleep state in the state of detecting human body signals, and when the radar module 2 does not detect human body signals for a long time or multiple times, the stove starts the "sentinel mode" accordingly. At this time, the radar module 2 continuously detects the human body signals near the stove, and controls and adjusts the use state of the stove when it is determined that there is no one, such as recording the length of time without supervision, and adjusting the cooking firepower size according to the length of time, or detecting the temperature near the cookware or whether there is liquid overflow to extinguish the fire and close the gas, thereby ensuring the safety of the stove when there is no one near the stove.

[0051] In summary, the control assembly with human sensing detection function provided by the utility model, including control module, radar module 2 and communication connecting piece 3, wherein, control module includes control PCB board 1 and the controller set on control PCB board 1, radar module 2 further includes radar PCB board 21 and mounting bracket 22, radar antenna and radar processor are equipped on radar PCB board 21, radar PCB board 21 is located on mounting bracket 22, mounting bracket 22 is detachably connected with control PCB board 1, so setting, can realize the human body response and monitoring near the stove through radar antenna, so as to realize when radar module 2 detects that there is no person near the stove, the stove can start "sentinel mode", and the control module realizes the takeover of the stove, to ensure that the stove maintains normal use state, in this way, the user can also ensure the normal use of the stove when leaving the vicinity of the stove, therefore, the use experience of the user is improved.

[0052] As shown in the figure, further, in some embodiments, the mounting bracket 22 is provided with an elastic buckle 221, and the control PCB board 1 is provided with a clamping hole 11, and the mounting bracket 22 and the control PCB board 1 are connected by the elastic buckle 221 clamped in the clamping hole 11. In this way, the mounting bracket 22 and the control PCB board 1 can be quickly assembled and disassembled by using the simple elastic buckle 221 and the clamping hole 11, which not only simplifies the installation structure, but also improves the assembly efficiency.

[0053] On the basis of the above, in some embodiments, the mounting bracket 22 further includes a bracket base 222 and two bracket connecting pieces 223, the radar PCB board 21 is arranged on the bracket base 222, and the two bracket connecting pieces 223 are arranged on the two sides of the bracket base 222, and each bracket connecting piece 223 is provided with an elastic buckle 221.

[0054] The bracket base 222 is the body structure of the mounting bracket 22, which is convenient for arranging the bracket connecting piece 223 and other components to realize the corresponding installation and connection between the control PCB board 1 and the radar PCB board 21. For example, the bracket base 222 and the two bracket connecting pieces 223 can be integrally formed to reduce the complexity of structural assembly and avoid installation deviation.

[0055] Specifically, when the mounting bracket 22 is connected with the control PCB 1, the position of the bracket connecting piece 223 provided with the elastic buckle 221 is moved towards the clamping hole 11, and the elastic buckle 221 can be deformed when the bracket connecting piece 223 passes through the clamping hole 11, so that the end of the bracket connecting piece 223 can smoothly pass through the clamping hole 11. After the elastic buckle 221 completely passes through the clamping hole 11, the elastic buckle 221 returns to the deformation, at this time, the elastic buckle 221 abuts to the other side of the clamping hole 11, and the mounting bracket 22 and the control PCB 1 are connected.

[0056] Further, the elastic buckle 221 is located at the end of the bracket connecting piece 223 away from the bracket base 222, and in the state that the elastic buckle 221 is connected in the clamping hole 11, the bottom surface of the mounting bracket 22 abuts to the upper surface of the control PCB 1.

[0057] That is, one end of the bracket connecting piece 223 is connected with the bracket base 222, and the other end of the bracket connecting piece 223 is used for connecting with the control PCB 1, since the two bracket connecting pieces 223 are arranged on the two sides of the bracket base 222, the bracket base 222 can ensure the connection between the bracket base 222 and the control PCB 1 to be reliable by arranging two bracket connecting pieces 223. On this basis, when the elastic buckle 221 is connected with the clamping hole 11, the bottom surface of the mounting bracket 22 abuts to the upper surface of the control PCB 1, so as to further ensure the mounting stability of the mounting bracket 22 relative to the control PCB 1, and ensure the stability of the radar module 2 in use, so as to ensure the detection accuracy.

[0058] Specifically, when the mounting bracket 22 is connected with the control PCB 1, the position of the bracket connecting piece 223 provided with the elastic buckle 221 is moved towards the clamping hole 11, and the elastic buckle 221 can be deformed when the bracket connecting piece 223 passes through the clamping hole 11, so that the end of the bracket connecting piece 223 can smoothly pass through the clamping hole 11. After the elastic buckle 221 completely passes through the clamping hole 11, the elastic buckle 221 returns to the deformation, at this time, the elastic buckle 221 abuts to the other side of the clamping hole 11, and the mounting bracket 22 and the control PCB 1 are connected.

[0059] It should be noted that when the control PCB 1 is placed in a horizontal direction, the bracket base 222 is connected with the control PCB 1 through the two bracket connecting pieces 223, at this time, the mounting bracket 22 can be understood as being placed on a horizontal plane, and correspondingly, the two bracket connecting pieces 223 are arranged on the left and right sides of the bracket base 222 along the horizontal direction. On this basis, the bracket connecting piece 223 can be arranged in a vertical direction to further facilitate the mounting of the mounting bracket 22 and the control PCB 1.

[0060] Please refer to Figure 6 As shown in the drawings, in some embodiments, the mounting bracket 22 further comprises two support steps 224, which are respectively arranged on the two sides of the bracket base 222, and the surface of each support step 224 forms a support surface, and the radar PCB board 21 is placed on the support surface. Further, the outer side edge of each support step 224 is provided with a first top limiting piece 225, and part of the first top limiting piece 225 extends upward of the support surface to form a limiting sliding groove 220 together with the support surface, and the two side edges of the radar PCB board 21 are respectively located in the limiting sliding groove 220 formed by the first top limiting piece 225 and the support surface of the two support steps 224.

[0061] That is, by arranging the two support steps 224 on the two sides of the bracket base 222, the two sides of the radar PCB board 21 can be supported, so that the radar PCB board 21 is placed on the mounting base. And the first top limiting piece 225 arranged on each support step 224 and the support surface can form a limiting sliding groove 220, so that the radar PCB board 21 can be conveniently installed, and the radar PCB board 21 can be positioned in the direction of the first top limiting piece 225 towards the support surface, thereby ensuring the fixing effect of the radar PCB board 21.

[0062] In specific implementation, the outer side edge of the side edge part of the radar PCB board 21 can be in abutment with the groove bottom of the limiting sliding groove 220, and the upper and lower surfaces of the radar PCB board 21 can be in abutment with the first top limiting piece 225 and the support surface, respectively, so that the radar PCB board 21 can be further ensured to be clamped between the first top limiting piece 225 and the support step 224 when sliding in the limiting sliding groove 220, thereby achieving further fixation of the radar PCB board 21.

[0063] It should be noted that when the radar PCB board 21 is placed, the side panel provided with the radar antenna is located upward, so that the radar antenna can conveniently emit and receive signals towards the outside of the structure. In addition, the up-down direction of the radar PCB board 21 mentioned in the above content refers to that in the vertical direction, the top of the radar PCB board 21 is upward, and the bottom of the radar PCB board 21 corresponds to the downward.

[0064] As Figure 6As shown, on the basis of the above, in a specific implementation, the first top limiting piece 225 formed on the two support steps 224 can be staggered along the lateral direction of the support base 222. In this way, the two first top limiting pieces 225 can be arranged at asymmetric positions on the left and right sides of the radar PCB 21, so that the two first top limiting pieces 225 can have a greater range of limiting effect on the radar PCB 21, thereby further ensuring the secure fixing of the mounting bracket 22 to the radar PCB 21.

[0065] It should be noted that the lateral direction of the support base 222 refers to the direction in which one of the support steps 224 faces the other support step 224, that is, the left-right direction of the support base 222. When the control PCB 1 is arranged in the horizontal direction, since the support base 222 as a whole is placed on the horizontal plane, the lateral direction of the support base 222 is also the horizontal direction at this time.

[0066] Further, in some embodiments, the bottom end of each support step 224 is further provided with an elastic abutting piece 226, which can be deformed away from the limiting groove 220, so that the side edge of the radar PCB 21 can be slid into the limiting groove 220, and the elastic abutting piece 226 can abut against the bottom of the radar PCB 21 when the bottom end of the radar PCB 21 moves to the support surface.

[0067] Please refer to Figure 5 and Figure 6 for details. Specifically, when the edge of the radar PCB 21 needs to extend into the limiting groove 220, the elastic abutting piece 226 can be deformed by extrusion to realize the installation of the radar PCB 21 on the mounting bracket 22. When the radar PCB 21 moves to the position where the edge of the radar PCB 21 is on the support surface, the extrusion of the radar PCB 21 to the elastic abutting piece 226 is disabled, and the elastic abutting piece 226 can thus recover from deformation and abut against the bottom of the radar PCB 21, thereby realizing the limiting support of the bottom of the radar PCB 21.

[0068] In this way, the limiting support of the installed radar PCB 21 can be realized without affecting the installation of the radar PCB 21 relative to the mounting base, and the structure is simple and convenient to install, while ensuring the fixing effect of the radar PCB 21.

[0069] Exemplarily, the specific structure of the elastic abutting piece 226 can be a protruding structure extending from the supporting surface of the supporting step 224 towards the upper portion of the supporting step 224. Specifically, the protruding structure extends towards the upper portion of the supporting step 224, which can extend in the vertical direction or extend at a certain inclined angle with the vertical direction, as long as the elastic abutting piece 226 can abut against the bottom of the radar PCB 21 after the bottom of the radar PCB 21 is moved to the supporting surface.

[0070] The elastic abutting piece 226 can limit and support the bottom of the radar PCB 21, and further limit and fix the top of the radar PCB 21.

[0071] Please refer to Figure 5 and Figure 6 In some embodiments, the top of the supporting step 224 is further provided with a second top limiting piece 227, and when the elastic abutting piece 226 abuts against the bottom of the radar PCB 21, the top of the radar PCB 21 abuts against the second top limiting piece 227.

[0072] In this way, when the elastic abutting piece 226 abuts against the bottom of the radar PCB 21, the top of the radar PCB 21 can abut against the second top limiting piece 227, so that the radar PCB 21 is fixed by the elastic abutting piece 226 and the second top limiting piece 227 in the extending direction from the bottom to the top of the radar PCB 21, and the radar PCB 21 is completely fixed relative to the mounting bracket 22, thereby further ensuring the fixing effect of the radar PCB 21 and avoiding the radar PCB 21 from shaking, so as to ensure the detection accuracy of the radar PCB 21 during use.

[0073] Further, the second top limiting piece 227 can be arranged on the supporting step 224, and one second top limiting piece 227 is arranged on each supporting step 224, which can further improve the fixing effect of the radar PCB 21. Exemplarily, the second top limiting piece 227 can be arranged on the top of one supporting step 224, and in other embodiments, the second top limiting piece 227 can be arranged on the top of each supporting step 224.

[0074] As shown in Figure 5 and Figure 7As shown, in some embodiments, the communication connector 3 further comprises a patch panel 32, and all the connection pins 31 are arranged on the patch panel 32. In addition, the mounting bracket 22 is further provided with a side abutting portion 228, which is located at a position of the mounting bracket 22 facing the connection pins 31, and in the connected state of the mounting bracket 22 and the control PCB 1, the patch panel 32 abuts against the side abutting portion 228.

[0075] In this way, after the radar module 2 is connected with the control PCB 1, the side of the communication connector 3 can be positioned and limited, thereby further ensuring the structural reliability of the communication connector 3 in use.

[0076] In specific implementation, the communication connector 3 is first inserted and fixed with the radar PCB 21, and then the radar PCB 21 and the communication connector 3 are fixed on the mounting bracket 22 together, so that the radar module 2 and the communication connector 3 are structurally integrated. Further, the mounting bracket 22 is clamped and fixed with the control PCB 1, in this process, the connection pins 31 of the communication connector 3 can be inserted into the insertion holes on the control PCB 1 correspondingly, and when the mounting bracket 22 is clamped and fixed with the control PCB 1, the connection pins 31 can be connected with the control PCB 1.

[0077] Since the connection pins 31 of the communication connector 3 have weak structural strength, they are easy to be bent when subjected to external force, thereby affecting the connection effect. Therefore, in order to further protect the communication connector 3, in a specific implementation, a mounting gap can be formed between the bottom surface of the patch panel 32 and the control PCB 1. In this way, when the radar module 2 is connected and fixed with the control PCB 1, the control PCB 1 will not abut against the patch panel 32 due to the existence of the gap, so that the connection pins 31 integrated by the patch panel 32 will not be subjected to external force, thereby ensuring the use safety of the connection pins 31.

[0078] For example, the size of the mounting gap can be set to 0.3-0.8 mm. Of course, in other embodiments, the mounting gap can also be set to other sizes of 0.3-0.8 mm.
