[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-5 The magnifying glass with a heating function includes a base 1 and a magnifying glass 2. The base 1 includes a heating device inside it and an air outlet 3 on the base 1. The air outlet 3 is located at the front of the magnifying glass 2. The heating device inside the base 1 delivers warm air along the air outlet 3. The warm air is delivered to the front of the magnifying glass 2 and acts on the hand to provide continuous heat, effectively solving the problem of cold hands in low-temperature environments. The magnifying glass 2 is also provided with a magnifying glass 4 for further magnification, which can be used to magnify smaller items.

[0024] The base 1 and the magnifying lens 2 are fixed together by a shaft. The magnifying lens 2 can be folded on the base. The base 1 has a shaft hole 112 inside, and the inner surface of the shaft hole 112 is evenly distributed with limiting ribs 114. The magnifying lens 2 has a rotating shaft 113 on both sides, and a positioning rib 115 is set on the rotating shaft 113. The outer contour of the limiting rib 114 is arc-shaped, and the outer contour of the positioning rib 113 is arc-shaped. The magnifying lens 2 is folded and fixed by the cooperation of the limiting rib 114 and the positioning rib 113. By setting the arc-shaped limiting rib on the inner surface of the shaft hole and the arc-shaped positioning rib on the surface of the rotating shaft, the rotating shaft can be easily rotated when an external force is applied, and when no external force is applied, the rotating shaft is positioned between the limiting ribs, so that the magnifying lens can be adjusted to a suitable angle.

[0025] The magnifying glass 2 shown is equipped with a fill light, which is embedded inside the magnifying glass. The fill light is the same as the existing LED makeup mirror light, which is powered by an LED light strip set on the back of the magnifying glass.

[0026] The heating device shown includes an electric heater, which converts heat into energy through an external power source and then sends it out. The base 1 shown has a heating channel inside, and a heating wire 11 and a blower are installed inside the channel. The heating wire 11 is fixed inside the heating channel, and the blower includes a miniature electric fan 10.

[0027] The base 1 shown has at least two heating channels, including a left heating channel 7 and a right heating channel 8. The dual heating channels can provide a larger heat source and the air supply surface on the left and right sides is wider.

[0028] The base 1 shown includes a temperature sensing device 12 located at the air outlet 3. The temperature sensing device 12 is connected in series with the heating device circuit. The temperature sensing device detects the temperature of the air outlet. The surface of the base 1 is provided with a control panel 111, which is connected to the circuit board inside the base. The circuit board is connected in series with the heating device, the temperature sensing device, and the supplementary light. The base 1 is powered by an external power supply. The control panel is connected to the external power supply through a circuit. The control panel has three preset temperature settings for the heating device: 40°C, 45°C, and 50°C. Users can select the setting as needed. The preset temperature is 55°C when the power is off. When the temperature sensing device detects that the air outlet temperature is higher than 55°C, the circuit board cuts off the power to the heating device.

[0029] The base 1 shown is equipped with a storage battery 13, which can be used as a power source.

[0030] The base 1 shown is equipped with heat insulation cotton, which is placed on the inner surface of the base and located in the heating channel, which can effectively avoid the problem of excessive temperature in the channel.

[0031] This magnifying glass is normally powered by an external household power supply. After being plugged in, the heating device is powered through the control panel. The heating wire heats the air in the heating channel, and a miniature electric fan delivers the hot air to the outside through the air outlet. Then, cold air from the outside is drawn into the heating channel through the air supply channel, and this cycle continues to provide heat. A temperature sensor is installed at the air outlet to monitor the outlet temperature. When the outlet temperature is higher than 55°C, the heating device immediately cuts off the power. When the outlet temperature is lower than 30°C, the heating device starts working again. This cycle continues, effectively saving power while maintaining heating.

[0032] This magnifying glass is primarily intended for use in low-temperature environments for delicate handicrafts, reading by the elderly, and other scenarios requiring magnification. Its built-in warm air device can provide warm air to the hands to prevent them from being affected by the low temperature.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
