Description

Technical Field

[0001] The present invention relates to the technical field of signal control and detection of small household appliances, and in particular to a signal detection conversion module. Background Art

[0002] With the improvement of living standards in modern society, people pay more and more attention to health and wellness. Pure glassware has been widely used due to its harmless characteristics. In contrast, stainless steel or metal utensils commonly used in traditional small household appliances are prone to scale formation during heating and may release heavy metals that are harmful to the human body. For example, the above problems often occur in health pots, coffee machines, electric kettles and electric hot pots. Therefore, these devices gradually turn to the use of pure glassware.

In order to improve the safety of the equipment and the user experience, it is usually necessary to detect whether there is a vessel placed on the equipment and to detect the water temperature and water level in the vessel. Only when the presence of the vessel is detected can the subsequent heating process be carried out; the detection of water temperature can ensure that the heated liquid reaches the ideal temperature; and the detection of water level can effectively prevent the occurrence of dry burning.

[0032] With the improvement of living standards in modern society, people pay more and more attention to health and wellness. Pure glassware has been widely used due to its harmless characteristics. In contrast, stainless steel or metal utensils commonly used in traditional small household appliances are prone to scale formation during heating and may release heavy metals that are harmful to the human body. For example, the above problems often occur in health pots, coffee machines, electric kettles and electric hot pots. Therefore, these devices gradually turn to the use of pure glassware.

[0033] However, in the manufacturing process of pure glassware, such as blowing, molding, extrusion and other processes, it is difficult to open holes in the vessel or assemble structural functional parts. As a result, pure glassware usually exists as an independent individual, completely separated from the components that need to be powered. In order to improve the safety of the equipment and the user experience, it is usually necessary to detect whether there is a vessel placed on the equipment and to detect the water temperature and water level in the vessel. Only when the presence of the vessel is detected can the subsequent heating process be carried out; the detection of water temperature can ensure that the heated liquid reaches the ideal temperature; and the detection of water level can effectively prevent the occurrence of dry burning.

[0034] In insulating containers such as pure glass products, due to the limitations of the application of traditional pressure sensors, temperature sensors and water level sensors in insulating containers, they cannot be directly applied inside existing insulating containers. Therefore, it is necessary to develop new sensor technologies to meet the application needs of insulating containers in small household appliances.

[0035] The present invention proposes a signal detection conversion module 100, which is intended to detect the presence or absence of an insulating container, and the water temperature and water level of the insulating container.

[0036] See also Figures 1 to 4In one embodiment of the present invention, the signal detection conversion module 100 includes a PCB circuit substrate 1, a water level detection component 2, a temperature detection component 3, a coupling control switch 4 and an integrated signal processing component 5. The water level detection component 2 is arranged on the PCB circuit substrate 1, and is used to detect whether there is liquid and the height of the liquid in the container; the temperature detection component 3 is movably arranged on the PCB circuit substrate 1, and is used to detect the temperature of the container; the coupling control switch 4 is arranged between the temperature detection component 3 and the PCB circuit substrate 1; the integrated signal processing component 5 is arranged on the PCB circuit substrate 1, and is connected to the water level detection component 2 circuit. Among them, the temperature detection component 3 is pressed, driving the coupling control switch 4 to move relative to the PCB circuit substrate 1 to form a first position and a second position. In the first position, the coupling control switch 4 is connected to the integrated signal processing component 5; in the second position, the coupling control switch 4 is disconnected from the integrated signal processing component 5.

[0037] The signal detection conversion module 100 includes a PCB circuit substrate 1, a water level detection component 2, a temperature detection component 3, a coupling control switch 4 and an integrated signal processing component 5. The water level detection component 2 is arranged on the PCB circuit substrate 1. The integrated signal processing component 5 senses the weak current change of the conductive mineral in the liquid in the insulating container through the water level detection component 2 to judge whether there is liquid and the height of the liquid. The temperature detection component 3 is not only used for the function of detecting the temperature of the insulating container, but also can move relative to the PCB circuit substrate 1, using the gravity of the insulating container itself or the extrusion tension of the structure as a trigger action to drive the coupling control switch 4 to connect or disconnect with the integrated signal processing component 5. The integrated signal processing component 5 converts the connection or disconnection signal of the circuit into a signal for identifying whether there is a container, thereby intelligently judging whether the signal detection conversion module 100 has contacted the insulating container. Only when the signal detection conversion module 100 contacts the insulating container, the temperature detected by the temperature detection component 3 is considered to be a valid detection temperature, thereby solving the problem of invalid temperature detected by the signal detection conversion module 100 when it does not contact the insulating container. Secondly, the integrated signal processing component 5 processes the collected signals and then issues instructions to control the small household appliances to complete various simulation states, such as: zero-power standby, automatic water addition, automatic tea brewing, automatic recovery of memory programs, automatic constant temperature and other simulation scene functions, thereby realizing artificial intelligence home.

[0038] In one embodiment, see Figures 2 to 4The PCB circuit substrate 1 is provided with a bracket 11, and the bracket 11 and the PCB circuit substrate 1 are enclosed to form a movement space 13; the PCB circuit substrate 1 is provided with a first through hole 12, and the bracket 11 is provided with a second through hole 112 corresponding to the first through hole 12, and the temperature detection component 3 is movably inserted into the first through hole 12 and the second through hole 112; the coupling control switch 4 is sleeved on the outside of the temperature detection component 3 and is located in the movement space 13, and the signal detection conversion module 100 also includes an elastic member 6, and the two ends of the elastic member 6 are elastically connected to the coupling control switch 4 and the bracket 11 respectively.

[0039] In this embodiment, the PCB circuit substrate 1 is not only the structural basis of the entire signal detection conversion module 100, but also a contact terminal 141 is provided on the PCB circuit substrate 1. The contact terminal 141 is connected to the integrated signal processing component 5 through the judgment circuit 14 to judge whether there is a vessel. The temperature detection component 3 is movably arranged on the PCB circuit substrate 1 for directly contacting the insulating vessel. After the temperature detection component 3 is subjected to pressure, it can move along its own axial direction. The coupling control switch 4 is sleeved on the outside of the temperature detection component 3. When the temperature detection component 3 is not subjected to pressure, the coupling control switch 4 is maintained in connection with the contact terminal 141 under the support of the elastic member 6, the judgment circuit 14 is in a connected state, and the coupling control switch 4 is in the first position. At this time, the signal detection conversion module 100 is in a standby state, ready to respond to the upcoming detection task. Once an insulating vessel is placed on the signal detection conversion module 100, the temperature detection component 3 is pressed and moves along its axial direction, driving the coupling control switch 4 and the elastic member 6 to move until reaching the second position. In the second position, the elastic member 6 is in a compressed state due to being compressed, and the connection between the coupling control switch 4 and the contact terminal 141 is disconnected. The integrated signal processing component 5 can judge that a vessel is placed in the signal detection conversion module 100 at this time through the disconnection signal sent by the judgment circuit 14. In this way, the detection of the presence or absence of a vessel is achieved by changing the on-off state of the judgment circuit 14. Among them, the elastic member 6 can be a spring, a shrapnel or rubber and other elastic materials. The elastic member 6 can withstand large deformation and quickly return to its original state after the external force is removed. When the temperature detection component 3 is subjected to an external force, the elastic member 6 can ensure that the coupling control switch 4 moves smoothly to disconnect the judgment circuit 14; when the external force is removed, the elastic member 6 releases the elastic potential energy, returns to its original state, and holds the coupling control switch 4 against the PCB circuit substrate 1, thereby ensuring that the judgment circuit 14 is connected.

[0040] A bracket 11 is provided on the PCB circuit substrate 1. The bracket 11 is installed on the PCB circuit substrate 1 by rivets. The PCB circuit substrate 1 is provided with a first through hole 12. The bracket 11 is correspondingly provided with a second through hole 112. The temperature detection component 3 is movably provided through the first through hole 12 and the second through hole 112, and can move along the axis direction of the first through hole 12 and the second through hole 112. A motion space 13 is formed between the PCB circuit substrate 1 and the bracket 11. The coupling control switch 4 and the elastic member 6 are provided in the motion space 13. The two ends of the elastic member 6 respectively abut against the PCB circuit substrate 1 and the bracket 11, so that the coupling control switch 4 can move smoothly along the axis direction of the temperature detection component 3 in the motion space 13.

[0041] In one embodiment, see Figures 2 to 4 The temperature detection assembly 3 includes a sensing tube 31 and a temperature detection body 32. The sensing tube 31 is movably inserted into the first through hole 12 and the second through hole 112. The coupling control switch 4 is sleeved on the outside of the sensing tube 31. The sensing tube 31 is provided with a receiving cavity 311. The temperature detection body 32 is disposed in the receiving cavity 311 and abuts against an end of the sensing tube 31 away from the opening.

[0042] In this embodiment, the temperature detection component 3 is provided with a sensing tube 31, and a receiving chamber 311 is provided inside the sensing tube 31. The receiving chamber 311 not only provides an installation environment for the temperature detection component 3, but also ensures the accuracy of temperature detection and prevents the temperature detection component 3 from external interference.

[0043] In one embodiment, see Figures 2 to 4 The sensing tube 31 includes a column 312 and a sensing portion 313. The column 312 is formed with a third through hole 3121 penetrating the column 312. The sensing portion 313 is connected to one end of the column 312 to close one end of the third through hole 3121. The column 312 and the sensing portion 313 are arranged to form a receiving cavity 311, and the temperature detection body 32 is in contact with the sensing portion 313.

[0044] It can be understood that the temperature detection body 32 is arranged in the accommodating cavity 311, and can contact one side of the sensing part 313. When the other side of the sensing part 313 contacts the insulating container, the sensing part 313 can transfer heat so that the temperature detection body 32 can detect the temperature of the insulating container. Among them, a spherical protrusion is arranged on the side where the sensing part 313 contacts the insulating container. The spherical protrusion not only increases the contact area between the sensing part 313 and the insulating container, improves the efficiency of heat transfer, but also reduces the friction with the surface of the insulating container through the spherical shape, thereby extending the service life of the sensing tube 31.

[0045] In one embodiment, see Figures 2 to 4The temperature detection body 32 includes a thermistor 321 and a harness 322. The thermistor 321 is disposed in the accommodating cavity 311 and abuts against the sensing portion 313. One end of the harness 322 is connected to the thermistor 321.

[0046] In this embodiment, the thermistor 321 is disposed in the accommodating cavity 311, and is used to receive heat transfer from the sensing portion 313, thereby realizing the measurement of the temperature of the vessel. The thermistor 321 has the characteristic of significantly changing the resistance value as the temperature changes, so that the thermistor 321 can convert the temperature change into the resistance value change, and then into a readable electrical signal. The wiring harness 322 is connected to the thermistor 321 and is connected to other circuit systems. When the thermistor 321 adjusts its resistance value as the temperature changes, the wiring harness 322 transmits this signal to the circuit system, and the circuit system can obtain the current temperature of the insulating vessel through the signal.

[0047] In one embodiment, see Figures 2 to 4 The coupling control switch 4 includes a coupling block 42 and a connecting block 41. The coupling block 42 is connected to the temperature detection component 3, and a mounting groove 4221 is provided on the side of the coupling block 42 facing the PCB circuit substrate 1. The connecting block 41 is arranged in the mounting groove 4221. The temperature detection component 3 drives the coupling block 42 and the connecting block 41 to move, so that the connecting block 41 is connected or disconnected with the integrated signal processing component 5.

[0048] In this embodiment, the coupling block 42 is directly connected to the sensing cylinder 31, and a mounting groove 4221 for mounting the connecting block 41 is provided on the side of the coupling block 42 facing the PCB circuit substrate 1, so as to ensure that the connecting block 41 can stably move with the coupling block 42. The connecting block 41 can move relative to the contact terminal 141 of the judgment circuit 14 under the drive of the sensing cylinder 31, so as to connect or disconnect the two contact terminals 141. Generally, the connecting block 41 is made of metal and is used to connect the two contact terminals 141.

[0049] In one embodiment, see Figures 2 to 4 The coupling block 42 includes a first coupling portion 421 and a second coupling portion 422. The first coupling portion 421 is connected to the temperature detection component 3, and the first coupling portion 421 is provided with a limiting groove 4211, and one end of the elastic member 6 is inserted into the limiting groove 4211. The second coupling portion 422 is connected to the first coupling portion 421, and a mounting groove 4221 is formed on the side of the second coupling portion 422 away from the first coupling portion 421.

[0050] In this embodiment, a limiting groove 4211 is provided on the side of the first coupling portion 421 facing the elastic member 6, and the limiting groove 4211 not only provides a movement space 13 for the elastic member 6, but also ensures that the elastic member 6 can be deformed along the extension direction of the limiting groove 4211 when subjected to force, thereby ensuring the stability of the coupling block 42 when moving. The mounting groove 4221 is provided on the side of the second coupling portion 422 facing the PCB circuit substrate 1, so that the connecting block 41 can be connected or disconnected with the two contact terminals 141 during the movement of the connecting block 41.

[0051] In one embodiment, see Figures 2 to 4 The first coupling part 421 and the second coupling part 422 are both cylindrical, and the radius of the first coupling part 421 is smaller than the radius of the second coupling part 422 . The first coupling part 421 and the second coupling part 422 are coaxially arranged, and the temperature detection component 3 passes through the first coupling part 421 and the second coupling part 422 .

[0052] In this embodiment, the first coupling portion 421 and the second coupling portion 422 are both cylindrical, and the first coupling portion 421 and the second coupling portion 422 are coaxially arranged, and the induction tube 31 is arranged through the central axis of the first coupling portion 421 and the second coupling portion 422, so that the coupling block 42 is subjected to balanced force during the movement. The radius of the first coupling portion 421 is smaller than the radius of the second coupling portion 422, which not only makes the coupling block 42 have a certain sense of hierarchy in structure, but also the radius of the second coupling portion 422 is larger, which is more convenient to provide stable support, so as to ensure that the connecting block 41 can be stably connected with the contact terminal 141.

[0053] In one embodiment, see Figures 2 to 4 The water level detection component 2 includes an isolation shell 21 and a water level detection rod 22. The isolation shell 21 is disposed on the PCB circuit substrate 1, and the isolation shell 21 and the PCB circuit substrate 1 are surrounded to form an isolation cavity 211. The water level detection rod 22 is disposed on the PCB circuit substrate 1, and a portion of the water level detection rod 22 is located in the isolation cavity 211, and the water level detection rod 22 is connected to the integrated signal processing component 5.

[0054] In this embodiment, a water level detection rod 22 is also provided on the PCB circuit substrate 1. The water level detection rod 22 determines whether there is liquid and the height of the liquid by sensing the weak current change of the conductive minerals contained in the liquid in the insulating container. The integrated signal processing component 5 is connected to the water level detection rod 22 through the water level circuit 15. When the liquid level in the water level detection rod 22 is lower than the preset safety height, the water level detection rod 22 cannot detect the liquid, and the integrated signal processing component 5 controls the alarm and automatically cuts off the power supply to ensure the safe operation of the device. Optionally, an isolation shell 21 is provided outside the water level detection rod 22 to prevent users or other objects from directly contacting the water level detection rod 22, thereby avoiding safety hazards such as electric shock.

[0055] In one embodiment, see Figures 2 to 4 The PCB circuit substrate 1 is also provided with a power port 16 and an output port 17, and the integrated signal processing component 5 is respectively connected to the power port 16 and the output port 17 circuits.

[0056] In this embodiment, the integrated signal processing component 5 is used to receive and process the conductive signal from the water level circuit 15, and to perform the logic judgment task in the judgment circuit 14. In particular, the integrated signal processing component 5 is a touch chip, which can not only monitor the water level of the liquid in the vessel in real time, and perform corresponding operations according to the preset logic judgment rules, but also interact with the user through touch operations, thereby improving the practicality and user experience of the device. A power port 16 and an output port 17 connected to the integrated signal processing component 5 circuit are also provided on both sides of the integrated signal processing component 5. The power port 16 can be connected to a standard power plug or a battery pack, thereby providing a stable power supply for the integrated signal processing component 5. When the integrated signal processing component 5 processes the signals of the water level circuit 15 and the judgment circuit 14, it will immediately transmit the results to the external device through the output port 17 for the user to view or perform corresponding operations.

[0057] The detection process of the signal detection conversion module 100 of the present invention is as follows:

[0058] The insulating container is placed on the signal detection conversion module 100. The insulating container generates pressure on the sensing part 313, and the sensing tube 31 moves accordingly, so that the connecting block 41 is disconnected from the judgment circuit 14, and the signal detection conversion module 100 detects the placement of the insulating container. The temperature detection body 32 located in the accommodating cavity 311 detects the temperature of the insulating container through the heat transfer of the sensing part 313. The water level detection rod 22 located on the PCB circuit substrate 1 detects whether the liquid height in the insulating container is higher than the safe height based on the weak current change of the conductive minerals in the liquid. Once the liquid height is lower than the safe height, an alarm is sounded and heating is stopped. After the insulating container is taken away, the elastic member 6 is reset, so that the connecting block 41 is reconnected with the judgment circuit 14.

[0059] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
