[0002] With the development of society and the improvement of people's quality of life, smart homes have begun to be applied to all aspects of life. Many commonly used furniture plus some smart products make people's lives more convenient. At present, most people have the habit of drinking a cup of warm water before going to bed. Therefore, in order to provide users with a more convenient and intelligent water cup heating service, traditional warm cup pads have also begun to be used on bedside tables.

[0003] Among them, the cup warmer is a common heating device, which is mainly used to heat the liquid in containers such as cups and bottles to a suitable temperature. Usually, the cup warmer adopts electric heating to heat the heating material on the surface of the mat by converting electrical energy into thermal energy, thereby achieving the heating effect.

[0004] When existing cup warmers are used on bedside tables, especially when placed in children's rooms or baby rooms, there are often safety hazards. For example, when a child accidentally touches the cup warmer switch or places fingers or other body parts on the cup warmer, it is easy to cause burns. Especially during the heating process, the heating temperature is high. If there are no effective protective measures, when other flammable items are placed on the cup warmer, it is very easy to cause fire or other safety accidents. In addition, once the existing cup warmers are turned on, they are basically in a state of continuous heating, which not only consumes power continuously, but also causes the performance of the cup warmers to decline and the service life to be shortened due to long-term continuous heating. Summary of the invention

[0005] In order to solve the technical defects raised in the above-mentioned background technology, the purpose of the present invention is to provide a safe and reliable bedside table cup warmer to solve the problem that the cup warmer in the prior art is easy to cause burns due to accidental touch and has high energy consumption.

[0038] The following is combined with Figure 1-7 , an embodiment of a safe and reliable bedside table cup warmer of the present invention is further described in detail.

[0039] Embodiment 1

[0040] A safe and reliable bedside table warming cup pad, such as Figures 1 to 3 As shown, it includes a shell 1, a sensor module 2, a heating module 3 and a control module 4 arranged on the shell 1. The shell 1 is provided with a micro switch 5 on one side of the heating module 3, and the micro switch 5 is used to connect or disconnect the power supply; the sensor module 2 is used to identify and detect the material of the heating cup placed on the micro switch 5; the heating module 3 is used to heat the cup; the control module 4 is used to control the heating module 3 to heat or cut off the power; the sensor module 2, the heating module 3 and the control module 4 are interconnected to form an anti-mistaken touch protection structure; when the heating module 3 is heating, the sensor module 2 automatically senses and accurately identifies the type of the heating body, and automatically triggers the anti-mistaken touch protection function, so that the control module 4 cuts off the power supply and stops heating.

[0041] Specifically, the cup warmer is arranged on the bedside table, which can not only automatically heat the cup, but also arrange a sensing device, a heating module 3 and a control module 4 in the cup warmer, so that the cup warmer can automatically detect whether a cup is placed thereon, and automatically control the heating temperature and can automatically cut off the power after preventing accidental touch, thereby solving the problem that the existing bedside table is easily touched by children by mistake or blocked by other objects during the heating process, causing safety hazards; at the same time, in order to better reflect the function of the cup warmer, the surface cabinet panel of the bedside table should be made of rock board, ceramic or metal and other materials, and wooden boards should be avoided, because wooden boards are not resistant to high temperatures and have poor thermal conductivity, and safety hazards are likely to exist during long-term heating; in addition, during use, you only need to place the cup on the cup warmer to press the microswitch 5, and the heating module 3 is energized for heating operation. After the cup is removed, the power can be automatically cut off, and empty burning can be effectively prevented, with good energy-saving effect.

[0042] Among them, the protection operation of the anti-accidental touch protection structure is: when the heating module 3 is heating, when a child's finger or other flammable items are placed on the surface of the warm cup pad, the sensor module 2 automatically senses and accurately identifies the material type of the heating body, and cuts off the power supply through the control module 4 to stop heating.

[0043] It is worth mentioning that in order to enhance the function of the bedside table and facilitate users to charge at night, a wireless charging module is provided on the front side of the bedside table located at the cup warmer, so that users can place their mobile phones on the bedside table for charging after returning home at night.

[0044] In this embodiment, if Figure 4 As shown, a receiving cavity 11 and a mounting cavity 12 are provided on the housing 1 at the positions of the sensor module 2 and the control module 4 . The heating module 3 is arranged in the receiving cavity 11 ; the sensor module 2 and the control module 4 are arranged in the mounting cavity 12 .

[0045] Specifically, in order to further save space for the cup warmer, the accommodating cavity 11 opened on the shell 1 is of a circular structure, the heating module 3 is installed in the accommodating cavity 11, and a through hole is opened in the middle bottom of the accommodating cavity 11, one end of the micro switch 5 extends to the surface of the bedside table through the through hole, and the heating module 3 directly acts on the surface cabinet board of the bedside table, and in order to prevent other areas from being heated, the heating module 3 can only heat the accommodating cavity 11 area, thereby avoiding burns caused by accidental touch; and the installation cavity 12 opened on one side of the accommodating cavity 11 is of a rectangular structure, the control module 4 is installed at the bottom of the installation cavity 12, and the sensor module 2 is arranged inside. Under the detection of the sensor module 2, the objects placed on the heating module 3 area can be effectively identified, so that the control module 4 can select the corresponding heating mode or standby mode according to the object information.

[0046] In this example, the sensing module 2 includes a temperature sensor 21 and an object recognition sensor 22. The temperature sensor 21 is used to detect the ambient temperature in real time, and the object recognition sensor 22 is used to detect the material of the object placed on the micro switch 5. Both the temperature sensor 21 and the object recognition sensor 22 are connected to the control module 4 by signal.

[0047] Specifically, the temperature sensor can be set on the heating module 3 and connected to the control module 4, which can send the detected temperature to the control module 4. The control module 4 can also be used to adjust the unit power-on ratio of the heating module 3 according to the temperature detected by the temperature sensor and the current working temperature. Although the control module 4 has determined the unit power-on ratio of the heating module 3 according to the current working temperature, in actual applications, it may also be due to the influence of various factors (such as the heating time of the heating module 3, environmental factors, etc.), which may cause the temperature of the heating module 3 to deviate from the expected temperature when the heating module 3 works according to the unit power-on ratio corresponding to the current working temperature. At this time, the unit power-on ratio of the heating module 3 can be adjusted according to the actual temperature of the heating module 3 (that is, the temperature measured by the temperature sensor) so that the actual temperature of the heating module 3 can quickly reach the expected temperature and / or maintain at the expected temperature.

[0048] The object recognition sensor 22 adopts an IFM (vision) object recognition sensor 22, which uses vision to identify different types of objects and accurately determine the material of the object. In this way, even if a child accidentally places a finger or other body part in the heating area of ​​the cup warmer, or when a child accidentally presses the micro switch 5, the object recognition sensor 22 can send a related signal to the control module 4, and the control module 4 will then determine whether to perform heating or power-off operations. At the same time, the object recognition sensor 22 can also use vision technology to identify other flammable objects, and transmit the relevant information of the object to the control module 4, thereby recording and saving the information of the object.

[0049] In this embodiment, if Figure 5 As shown, the heating module 3 includes a heating disk 31 and a temperature limiter 32. The heating disk 31 is coiled in the accommodating cavity 11, and the heating disk 31 is connected in series with the micro switch 5. The temperature limiter 32 is arranged on the side wall of the accommodating cavity 11, and the temperature limiter 32 is used to limit the heating temperature of the heating disk 31 to not exceed 100°C.

[0050] Specifically, when the heating plate 31 heats the table top of the bedside table, in order to better limit the heating temperature of the heating plate 31, the heating temperature of the heating plate 31 is controlled by the temperature limiter 32, and the temperature limiter 32 can also control the heating temperature of the heating plate 31 not to exceed 100°C. The purpose of such design is, on the one hand, to avoid excessive temperature exceeding the heat resistance temperature of the bedside table, resulting in excessively high surface temperature of the entire bedside table, which may easily cause burns; on the other hand, it can avoid overheating of the water cup; in addition, it should be noted that the heating plate 31 and the microswitch 5 in the present invention are connected in series, and the microswitch 5 is connected to the power supply, that is, when the microswitch 5 is closed, the heating plate 31 is powered on and is in standby mode; and when the microswitch 5 returns to its original position, the power is disconnected, and the heating plate 31 is powered off and stops heating.

[0051] In this embodiment, the micro switch 5 is in a normally open state, and a transmission contact 51 is provided on the micro switch 5, and the transmission contact 51 passes through the housing 1;

[0052] When a water cup is placed, the transmission contact 51 is pressed and closed to turn on the power;

[0053] When no water cup is placed, the transmission contact 51 is reset to disconnect the power supply.

[0054] Specifically, the control principle of the micro switch 5 is a known technology, so it will not be described in detail here; the micro switch 5 is used as the control switch of the power supply, and the transmission contact 51 on the micro switch 5 is slightly higher than the table top of the bedside table. When a water cup is placed on the bedside table, the water cup presses down the transmission contact 51, and the transmission contact 51 is pressed down to connect the power supply, thereby starting heating; but in order to avoid dry burning, the weight of the cup in the empty cup state cannot press down the transmission contact 51, and the power supply cannot be connected for heating.

[0055] In this embodiment, the control module 4 includes a touch panel 41 and a PCB control board 42. The touch panel 41 is provided with a switch button 411, a child lock button 412 and a temperature setting button 413. The switch button 411, the child lock button 412 and the temperature setting button 413 are all electrically connected to the PCB control board 42. When the water cup is heated, the switch button 411 and the child lock button 412 must be pressed at the same time to unlock the heating module 3. The temperature setting button 413 is used to set the heating temperature.

[0056] Specifically, the touch panel 41 is embedded on the surface of the bedside table, which can not only improve the aesthetics of the bedside table, but also hide the touch panel 41, effectively preventing children from touching them by mistake. At the same time, the switch button 411, the child lock button 412 and the temperature setting button 413 arranged on the touch panel 41 are all controlled by touch. In order to better avoid accidental touching, the temperature setting button 413 is arranged between the switch button 411 and the child lock button 412, thereby increasing the distance between them, better avoiding accidentally touching the switch button 411 and the child lock button 412 at the same time, and effectively ensuring the safety of children.

[0057] When controlling the heating module 3 to heat, the user needs to press the switch button 411 and the child lock button 412 at the same time to power on the heating. Pressing only the switch button 411 or the child lock button 412 will not start the heating. If the switch button 411 is pressed first and then the child lock button 412 is pressed, or the opposite operation order is used, the heating function cannot be started, further enhancing the safety protection function against accidental touch.

[0058] In order to facilitate users to understand the current working status of the warm cup mat, a working warning light 414 is also provided on the touch panel 41. The working warning light 414 is always on in the heating state and flashes in the standby state; further, in addition to displaying the working status, the working warning light 414 can also be used to indicate whether there is an object on the warm cup mat. If there is an object on the warm cup mat, the working warning light 414 will emit a flashing blue light as a reminder. If there is no object on the warm cup mat, the working warning light 414 will not light up; at the same time, in order to further facilitate use, the working warning light 414 can also be set as a reminder function, that is, after heating to the preset temperature, the working warning light 414 can emit a double-sided strobe light, thereby reminding the user to drink water in time.

[0059] Embodiment 2

[0060] In this embodiment, if Figure 6 , 7 As shown, when the control module 4 controls the heating module 3 to perform heating, a heating control method for a warm cup pad is provided, comprising the following steps:

[0061] S1, the sensor module 2 automatically identifies whether there is a water cup placed on the bedside table and automatically identifies the material of the water cup;

[0062] S2, if the cup is placed on the micro switch 5, the micro switch 5 is pressed to turn on the power, the working warning light 414 starts to light up, and the switch button 411 and the child lock button 412 are pressed simultaneously for 1 to 3 seconds through the touch panel 41, and the heating plate 31 of the heating module 3 starts to heat;

[0063] S3, if the water cup is picked up or accidentally touches the heating area, the micro switch 5 is reset, the power is disconnected, the working warning light 414 starts to flash, the heating module 3 stops heating, and the control module 4 is in standby state;

[0064] S4. After the water cup is heated to a preset temperature, the control module 4 controls the heating module 3 to continue heating and keeping warm.

[0065] In this embodiment, when the heating module 3 is controlled to perform heating in step S2, pressing the switch button 411 or the child lock button 412 alone cannot unlock the heating, and the heating temperature can be preset through the temperature setting button 413 during the heating process.

[0066] Specifically, the purpose of setting the child lock button 412 is to prevent children from accidentally touching the switch button 411, causing the cup warmer to heat up. The heating temperature of the cup warmer can reach up to 100°C, so there is a safety hazard. The child lock button 412 can further enhance the safety performance of the cup warmer, so that the cup warmer needs to press the switch button 411 and the child lock button 412 at the same time to unlock the heating, and pressing either one of them will not start; at the same time, a temperature setting button 413 is set between the switch button 411 and the child lock button 412, so that the user can select the heating temperature according to needs.

[0067] In this embodiment, during the continuous heating process in step S4, the control module 4 is provided with an automatic power-off protection mechanism, that is, if the sensor module 2 does not detect the cup within a certain period of time, or after continuous heating and heat preservation for 24 hours, the control module 4 automatically enters sleep mode or automatically shuts down.

[0068] Specifically, in order to improve the safety performance of the cup warmer, when heating the cup, the cup needs to be placed in the designated position area of ​​the bedside table so that it is just on the top of the heater for heating. At the same time, in order to prevent the problem of taking the cup halfway, which causes the heating module 3 to continue heating, the sensor module 2 is used to monitor the heating status in real time. That is, if the sensor module 2 does not detect the cup within a certain period of time, or after continuous heating and heat preservation for 24 hours, the control module 4 automatically enters the sleep mode or automatically shuts down, so that it can reduce energy loss while greatly improving safety performance.

[0069] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
