Description

Technical Field

[0001] This invention relates to the field of water container technology, and in particular to a vehicle-mounted heating cup. Background Technology

[0002] Most car-mounted heated cups are currently placed on a cup holder and use the car's power supply to heat the cup body, thereby raising the temperature of the water inside.

[0003] The cup is usually heated and the temperature settings are switched by pressing buttons. However, the limited space in the car makes button operation inconvenient and prone to misoperation. In addition, the driver must stop the car to operate the buttons, and cannot heat the cup or switch the temperature settings while driving, which means blind operation is not possible. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a car-mounted heated cup, which adopts a cup lifting detection program to control the heating control circuit, so as to enable the user to heat the cup and switch the heating temperature level while driving, thereby improving the ease of operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vehicle-mounted heated cup, comprising a cup body and a base;

[0006] The bottom of the cup body is provided with a heating element, a temperature measuring element, a first conductive ring and a second conductive ring. The heating element is connected to the first conductive ring through a conductive wire, and the temperature measuring element is connected to the second conductive ring through a conductive wire.

[0007] The base is equipped with a PCB board, a first conductive pin that works with a first conductive ring, and a second conductive pin that works with a second conductive ring. The PCB board is soldered with an MCU, a temperature detection circuit, a voltage detection circuit, a current detection circuit, a heating control circuit, and a buzzer circuit. The first conductive pin is connected to the current detection circuit, the voltage detection circuit, and the heating control circuit, and the second conductive pin is connected to the temperature detection circuit.

[0008] The signals detected by the temperature detection circuit, voltage detection circuit and current detection circuit are transmitted to the MCU. After being processed by the MCU, they are transmitted to the heating control circuit and the buzzer circuit respectively.

[0009] The MCU detects the temperature of the temperature sensing element in real time through a temperature detection circuit to determine the placement status of the cup on the base;

[0010] The MCU uses a cup-lifting detection program to control the heating control circuit.

[0011] This invention employs a cup-lifting detection program to control the heating control circuit. While driving, the driver can heat the cup and switch heating temperature levels simply by lifting the cup, significantly improving ease of operation. Furthermore, this operation is blind, enhancing driving safety.

[0012] Furthermore, the PCB board is powered by a power supply.

[0013] Furthermore, the heating element and temperature measuring element are installed in direct contact with the inner liner of the cup. The heating element can quickly transfer heat to the inner liner of the cup and make the data measured by the temperature measuring element accurate.

[0014] Furthermore, a certain installation distance d is maintained between the heating element and the sensing point of the temperature measuring element to avoid the direct conduction of heat from the heating element affecting the temperature measurement of the temperature measuring element, thus avoiding a certain leading deviation between the temperature of the liquid in the cup to be sensed and the temperature measurement error.

[0015] Furthermore, the installation distance d is preferably 3mm ≤ d ≤ 20mm.

[0016] Furthermore, the process of the cup-lifting detection procedure is as follows:

[0017] It has multiple temperature settings, D1 to D, arranged from smallest to largest. n When the cup-lifting state is valid, that is, the electrical connection between the second conductive pin and the second conductive ring is broken, the cup-lifting state is valid when the cup-lifting time t>T2, where T2 is the time of erroneous operation caused by the electrical disconnection between the second conductive pin and the second conductive ring due to the bumps and vibrations during vehicle movement. When t≥T3, the default is the cup-lifting state when the user is drinking normally, where T3 is the time boundary between the cup-lifting state for switching temperature levels and the normal drinking state. When the user puts the cup back on the base, the original temperature level is maintained, and no temperature level switching is performed. When T2<t<T3, the default is that the user is using the cup-lifting operation to switch temperature levels.

[0018] During the temperature setting switching process, the MCU will provide status feedback through a buzzer and / or indicator lights to facilitate user operation.

[0019] Furthermore, the preferred range of T2 is 0s < T2 ≤ 1s; the preferred range of T3 is 1s < T3 < 3s.

[0020] Furthermore, during the temperature setting switching process, the system provides prompts for different temperature settings through the number of beeps, the length of the beep, and the frequency / volume of the beep, making it easier for users to quickly identify the corresponding temperature setting when operating while driving.

[0021] Furthermore, the base is equipped with buttons, and the PCB board is also soldered with operation button circuitry and indicator light circuitry; the MCU also uses a temperature level switching program to control the heating control circuit, and the flow of the temperature level switching program is as follows:

[0022] It has multiple temperature settings, D1 to D, arranged from smallest to largest. n When the cup is placed on the base and an electrical connection is established, the base is powered on and starts operating at temperature setting D1 by default.

[0023] When the heating cup is placed on an open platform, the user can perform normal operation using the buttons on the base. After the MCU detects a valid button trigger signal, it will determine whether a temperature level switch has occurred. If the switch is successful, the buzzer and / or indicator light will provide status feedback, and the switched temperature level will be executed. When the button trigger signal time T > T1, T1 is the valid trigger time of the button, which is a long press operation by default, switching between power on and power off states. Conversely, when the button trigger signal time T ≤ T1, it is a short press operation, switching the temperature level.

[0024] In addition to using a cup-lifting detection program to control the heating control circuit, this invention can also use a temperature level switching program to control the heating control circuit, making it suitable for multiple application scenarios.

[0025] Furthermore, the range of T1 is: 1s < T1 < 4s.

[0026] Compared with the prior art, the beneficial effects of this invention are as follows:

[0027] 1. The cup-lift detection program controls the heating control circuit, enabling users to heat the cup and switch heating temperature levels while driving, improving ease of operation; since this operation is blind, it enhances driving safety.

[0028] 2. Increase the filtering time for misoperation during cup lifting detection to avoid accidental triggering of operations due to vehicle bumps and vibrations in in-vehicle use scenarios.

[0029] 3. Added a beeping sound to indicate when shifting gears by lifting the cup, improving the ability to distinguish and identify the gear position during blind operation in vehicle mode.

[0030] 4. It adopts a dual control method with a cup lifting detection program and a temperature level switching program, which is suitable for multiple usage scenarios and solves the inconvenience of limited operating space in the case of car cup holders and cup holders.

Detailed Implementation

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0039] Reference Figure 1-4 A car-mounted heated cup includes a cup body 1 and a base 2. The bottom of the cup body 1 is provided with a heating element 3, a temperature measuring element 4, a first conductive ring 6 and a second conductive ring 7. The heating element is connected to the first conductive ring 6 through a conductive wire 5, and the temperature measuring element 4 is connected to the second conductive ring 7 through a conductive wire 5. The base 2 is equipped with a button, a PCB board 8, a first conductive pin 18 that works with the first conductive ring, and a second conductive pin 19 that works with the second conductive ring.

[0040] The PCB board is equipped with an operation button circuit 15, an MCU 16, a temperature detection circuit 12, a voltage detection circuit 10, a current detection circuit 11, a heating control circuit 14, an indicator light circuit 13, and a buzzer circuit 17. The first conductive pin 18 is connected to the current detection circuit 11, the voltage detection circuit 10, and the heating control circuit 14, and the second conductive pin 19 is connected to the temperature detection circuit 12.

[0041] The signals detected by the temperature detection circuit 12, voltage detection circuit 10, current detection circuit 11 and operation button circuit 15 are transmitted to the MCU 16. After being processed by the MCU 16, they are transmitted to the heating control circuit 14, the buzzer circuit 17 and the indicator light circuit 13 respectively.

[0042] The MCU 16 detects the temperature of the temperature sensing element 4 in real time through the temperature detection circuit 12 to determine the placement status of the cup body 2 on the base 1.

[0043] The MCU 16 uses a cup-lifting detection program and a temperature level switching program to control the heating control circuit 14.

[0044] The PCB board 8 is powered by the power supply 9. The heating element 3 and the temperature sensing element 4 are installed in direct contact with the inner liner of the cup body 2. A certain installation distance d is maintained between the heating element 3 and the temperature sensing point of the temperature sensing element 4, where 3mm ≤ d ≤ 20mm.

[0045] like Figure 5 As shown, the flow of the cup-lifting detection procedure is as follows:

[0046] There are multiple temperature settings D1 to D4 arranged from smallest to largest. When the cup-lifting state is valid, the electrical connection between the second conductive pin 19 and the second conductive ring 7 is disconnected. When the cup-lifting time t > T2, it is a valid cup-lifting state. T2 is the time of erroneous operation caused by the electrical disconnection between the second conductive pin and the second conductive ring due to the bumps and vibrations during vehicle movement. When t ≥ T3, it defaults to the cup-lifting state when the user is drinking normally. T3 is the time boundary between switching the temperature setting and the normal drinking cup-lifting state. When the user puts the cup back on the base, the original temperature setting is executed, and no temperature setting switch is performed. When T2 < t < T3, it defaults to the user switching the temperature setting by using the cup-lifting operation.

[0047] During the temperature setting switching process, the MCU executes the status feedback prompt from the buzzer circuit.

[0048] The range of T2 is: 0s < T2 ≤ 1s; the range of T3 is: 1s < T3 < 3s.

[0049] During the temperature setting switching process, the switching prompts are indicated by the number of beeps, the length of the beep, and the frequency / volume of the beep.

[0050] like Figure 5 As shown, the flow of the temperature setting switching procedure is as follows:

[0051] It has multiple temperature settings D1 to D4 arranged from smallest to largest. When the cup is placed on the base and an electrical connection is established, the base is powered on and the device is turned on by default to execute temperature setting D1.

[0052] When the heating cup is placed on an open platform, the user performs normal operation via the buttons on the base. After the MCU detects a valid button trigger signal, it sequentially determines whether a temperature level switch has occurred. If the switch is successful, the buzzer circuit and / or indicator circuit provide status feedback and execute the switched temperature level. When the button trigger signal time T > T1, T1 is the valid trigger time of the button, which is a long press operation by default, switching between power on and power off states. Conversely, when the button trigger signal time T ≤ T1, it is a short press operation, switching the temperature level.

[0053] The range of T1 is: 1s < T1 < 4s.

[0054] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
