[0002] Water dispensers have greatly improved the convenience of drinking water in people's lives, such as traditional desktop water dispensers, instant water dispensers, etc. Taking instant water dispensers as an example, instant water dispensers are a kind of water heater that can quickly heat running water through a heating device and control the water temperature, flow rate, power, etc. through circuits to make the water temperature reach the target temperature.

[0003] The water heating parts of the heating devices currently installed on water dispensers are all similar in structure, that is, water is stored in a cavity and then heated. However, this method is prone to multiple heating of the cavity, and when there is no water, the power supply must be turned off, otherwise dry burning may occur and damage the heating device. Utility Model Content

[0004] The utility model aims to provide a heating device for a water dispenser, which solves the problem that the existing heating device is prone to multiple heating of the content in the cavity, and when there is no water, the power supply must be turned off, otherwise dry burning may occur and the heating device may be damaged.

[0006] The utility model discloses a heating device for a water dispenser, comprising a water inlet pipe, a heating pipe, a heat-insulating water storage chamber and a slider, wherein one end of the water inlet pipe is connected with a spiral tube, the spiral tube is arranged on the peripheral side of the heating pipe and is attached to the surface of the heating pipe, the interior of the heating pipe is fixedly connected with a connecting inner tube, one end of the connecting inner tube is arranged in the heat-insulating water storage chamber and is connected thereto, one end of the spiral tube is connected with the connecting inner tube, a slide rail is arranged on one side of the inner wall of the heat-insulating water storage chamber, the slider is arranged in the slide rail and slidably cooperates with the slide rail, one end of the slider is fixedly connected with a linkage rod, one end of the linkage rod is fixedly connected with an inclined rod, the interior of the inclined rod is rotatably connected with a fixed shaft, and one end of the fixed shaft is fixedly connected with the inner wall of the heat-insulating water storage chamber.

[0007] One end of the inclined rod is fixedly connected to a circular plate, one side of the circular plate is fixedly connected to a connecting rod, one end of the connecting rod is fixedly connected to a floating ball, and a pressure touch switch is installed on one side of the inner wall of the heat-insulating water storage chamber, and the pressure touch switch is arranged on one side of the slider.

[0008] A heat preservation wire is installed inside the heat preservation water storage cavity, and the heat preservation wire is electrically connected to the pressure touch switch.

[0009] A micro water pump is installed on the peripheral side of the water inlet pipe, a one-way valve is provided at the connection between the spiral tube and the connecting inner tube, and the pressure touch switch is electrically connected to the micro water pump and the heating tube; in the above structure, when the pressure touch switch is pressed by the slider, the insulation wire is energized and the micro water pump and the heating tube are de-energized; when the slider is moved away from the pressure touch switch, the micro water pump and the heating tube are energized and the insulation wire is de-energized.

[0010] A sealing plate is provided at the connection between the communicating inner tube and the heat-insulating water storage cavity, and the sealing plate is provided on the upper surface of the heat-insulating water storage cavity.

[0011] The utility model has the following beneficial effects:

[0012] The utility model is provided with a micro water pump, a spiral tube, a heating tube, a connecting inner tube and a heat-insulating water storage chamber. When there is no water in the heat-insulating water storage chamber, the slider does not squeeze the pressure touch switch, and the pressure touch switch energizes the micro water pump and the heating tube, so that drinking water enters the spiral tube from the water inlet pipe. When the water flows through the spiral tube, it is heated by the heating tube in turn, and then enters the heat-insulating water storage chamber from the connecting inner tube. As the water level rises, the float drives the connecting rod to swing along the fixed axis through the circular plate, and then drives the slider to move in the slide rail through the linkage rod, and squeezes the pressure touch switch, so that the pressure touch switch energizes the heat-insulating wire, and at the same time, the micro water pump and the heating tube are powered off, so as to effectively avoid the generation of thousands of boiling water. With the cooperation of the sealing plate and the one-way valve, the hot steam generated by the water in the heat-insulating water storage chamber will only be in the connecting inner tube and the heat-insulating water storage chamber, so as to improve the heat-insulating effect of the heat-insulating water storage chamber.
