Description

Technical Field

[0001] The utility model relates to the technical field of glass water cups, in particular to a low-power LED light-emitting glass water cup. Background Technique

[0002] In daily life, in order to prevent children from being scalded when drinking boiling water, parents will try the water temperature in the water cup by themselves to see if it is suitable for the child to drink. Occasionally, when the water temperature is not tried, there will be potential safety hazards such as scalding hands and mouths.

[0003] In order to avoid this situation, temperature-sensitive water cups use temperature sensors to collect the temperature in the water cup in real time, and display the real-time temperature or give a warning reminder through an LED warning light. However, most of the existing temperature-sensitive water cups use two types of temperature sensors, thermocouples and thermal resistors, during the temperature sensing period. The thermocouple outputs a millivolt voltage signal according to the temperature change, and the resistance value of the thermal resistor changes according to the temperature change. Both of them require a triode or an operational amplifier IC for operation and output. Such temperature control and display require continuous power supply or battery to provide power, and they are relatively large in size, relatively high in cost, the electronic control circuit is relatively complex, and the standby power consumption is also large. Due to being in a charged working state for a long time, the internal electronic components age relatively quickly, and their service lives are uneven, affecting the service life.

The top of the inner wall of the bottom cup cover 2 is in close contact with the top of the outer wall of the transparent glass connecting ring 3 through a sealing ring 4 made of silica gel, so as to form a sealed cavity inside the bottom cup cover 2. The low-power LED lighting control board is arranged in the sealed cavity;

[0022] An annular partition 5 extending upward is provided on the inner bottom surface of the bottom cover of the cup. The horizontal height of the top end of the annular partition 5 is lower than the horizontal height of the top end of the bottom cover of the cup 2. The transparent glass connecting ring 3 is located on the outer periphery of the annular partition 5. The low-power LED lighting control board is arranged in the inner circle of the annular partition 5. An annular stepped surface 6 recessed inward is provided on the top end of the annular partition 5, so that the horizontal height at the outer diameter of the annular partition 6 is higher than the horizontal height at its inner diameter.

[0023] The low-power LED lighting control board includes a PCB board 7, a battery holder 8 and a charge and discharge chip 9 provided on the bottom surface of the PCB board 7, a charging interface 10, a temperature control switch 11 (model KSD-01F D045) and an LED light source 12 provided on the top surface of the PCB board 7, and a rechargeable button battery 13 placed in the battery holder 8. The PCB board 7 is mounted and positioned on the annular stepped surface 6 at the top end of the annular partition. The charge and discharge chip 9 is an integrated chip structure, and internally integrates a charging control circuit 91, a discharge protection circuit 92 and a fault protection circuit, etc. The output end of the charging interface 10 is connected to the input end of the charging control circuit 91 of the charge and discharge chip 9, and the output end of the charging control circuit 91 of the charge and discharge chip is connected to the rechargeable button battery 13, so as to charge the rechargeable button battery 13.

When the temperature control switch 11 detects that the temperature does not exceed 45 °C, the normally open contact of the temperature control switch 11 always remains in the open state, and the LED light source 12 is in an open circuit and not lit, indicating that the water temperature in the transparent glass cup body 1 has not exceeded the maximum temperature that can be drunk and can be directly drunk. Since the temperature control switch 11 uses a normally open contact type, the standby power consumption of the water cup is zero when not in use, which is more energy-saving and has a longer service time.
