[0002] Hair dryers are common small household appliances that quickly dry hair after washing, making them an essential tool for modern hair care. However, the hot air they produce can burn the hair while drying it. Statistics show that over 50% of consumers have experienced scalp burns from hair dryers, some even resulting in scalp sensitivity or minor burns. To address this, we have developed a new type of hair dryer with automatic distance measurement and temperature control. Utility Model Content

[0005] To elaborate further, the first mounting base is provided with a plurality of first air outlets around the light-transmitting hole, and the second mounting base is provided with a second air outlet corresponding to the first air outlets.

[0006] To further elaborate, the second mounting base has a recessed portion, and at least two screw connecting posts are provided in the recessed portion. The screws pass through the ranging module and are threadedly connected to the screw connecting posts, thereby installing and fixing the ranging module at the second mounting base.

[0007] To elaborate further, the second mounting base is provided with several cable routing grooves, which are connected to the recessed portion.

[0008] To elaborate further, the wiring groove of the second mounting base is located between two adjacent second air outlets.

[0009] To elaborate further, the rear side of the second mounting base is provided with slots for engaging with the card holder, and the number of slots is the same as the number of wiring slots.

[0010] To elaborate further, a temperature sensor is provided at the rear end of the air duct housing, and the temperature sensor is fixedly installed at the rear air inlet seat.

[0011] The beneficial effects of this utility model are as follows: This utility model can adjust the temperature of the hot air blown out according to the distance between the air outlet of the hair dryer and the human head, thereby effectively avoiding burns to the scalp.

Detailed Implementation

[0021] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0022] Combined with appendix Figure 1 To be continued Figure 3As shown, a novel hair dryer with automatic distance measurement and temperature control includes a hair duct housing 10. A distance measurement module 20 is provided at the front end of the hair duct housing 10. The distance measurement module 20 is fixedly installed at the second mounting base 40. The distance measurement module 20 includes a distance measurement sensor 21, which is specifically a miniature, highly integrated dToF distance measurement sensor. The distance measurement module 20 is electrically connected to the temperature control module of the hair dryer.

[0023] The distance measuring module 20 can measure the distance between the air outlet of the hair dryer and the human head when using a hair dryer. When the distance between the air outlet of the hair dryer and the human head is too close, the temperature control module can automatically adjust the temperature of the air blown out by the hair dryer, thereby effectively avoiding burns to the scalp.

[0024] Combined with appendix Figure 4 As shown, a cover plate 211 is provided in front of the ranging sensor 21. The cover plate 211 is both transparent and blocks dust, oil, etc., to avoid affecting the normal operation of the ranging sensor 21. The cover plate 211 is fixedly installed at the first mounting base 30. The second mounting base 40 is located between the first mounting base 30 and the clamping bracket 50. The first mounting base 30 has a light-transmitting hole 31 at the location of the ranging sensor 21. The first mounting base 30 has several first air outlet holes 32 around the light-transmitting hole 31. The second mounting base 40 has second air outlet holes 41 corresponding to the first air outlet holes 32.

[0025] As attached Figure 7 As shown, the second mounting base 40 has a recessed portion 42, and at least two screw connecting posts 43 are provided in the recessed portion 42. The screws pass through the ranging module 20 and are threadedly connected to the screw connecting posts 43, thereby fixing the ranging module 20 in the second mounting base 40.

[0026] As attached Figure 7 As shown, the second mounting base 40 has several cable routing grooves 44, which are connected to the recessed portion 42. The wires of the ranging module 20 can pass through the recessed portion 42 of the second mounting base 40 and be laid along the cable routing grooves 44. The cable routing grooves 44 of the second mounting base 40 are located between two adjacent second air outlets 41.

[0027] As attached Figure 8 As shown, the rear side of the second mounting base 40 is provided with a slot 45 for engaging with the card holder 50, and the number of slots 45 is the same as the number of wiring slots 44.

[0028] Combined with appendix Figure 5 and attached Figure 6 As shown, a temperature sensor 60 is provided at the rear end of the air duct housing 10, and the temperature sensor 60 is fixedly installed at the rear air inlet seat 70. The temperature sensor 60 is specifically an NTC thermistor, used to detect the ambient temperature.
