Description

Technical Field

[0001] The utility model relates to the technical field of hair dryers, and particularly relates to a distance measuring device for a hair dryer. Background Art

[0002] With the development of technology, hair dryers have become indispensable electrical appliances in people's lives. However, when using traditional hair dryers, it is often difficult for users to accurately master the distance between the hair dryer and the hair or other objects, which may cause the hair to be over-blown or scalded, and even pose other safety hazards.

[0003] As the number of hair dryer users increases, people no longer only have the simple need for hot air blowing. For example, the patent with the authorization announcement number CN116348011A discloses a hair care appliance, which includes a heat source configured to emit heat, a position determination module configured to determine the position of the target hair, and a guiding mechanism for guiding the emitted heat from the heat source to the position of the target hair in response to the output of the position determination module. The hair dryer provided by the above patent can detect the distance between the hair dryer and the target object, but during the use process after installing the nozzle, there will be a potential problem that the distance measurement fails due to the occlusion of the nozzle. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is: overcoming the deficiencies of the prior art, providing a distance measuring device for a hair dryer, which can solve the problem that the distance measurement fails after installing the nozzle.

[0005] The technical solution of the utility model is as follows:

[0007] Preferably, the distance sensor is an infrared distance sensor or an optical distance sensor.

[0008] Preferably, a bracket is provided inside the hair dryer, the condenser lens is fixed at the front end of the bracket, and the distance sensor is fixed at the rear end of the bracket.

[0011] With the above solution, the light emitted by the distance sensor can be refracted by the condenser lens and projected onto the target object more concentratedly, making the distance measured by the distance sensor more accurate, eliminating the failure of distance measurement caused by the occlusion of the light emitted by the sensor at the air nozzle. The ambient temperature sensor is mainly used for temperature compensation according to the ambient temperature. The controller receives the signals of the distance sensor and the ambient temperature sensor and controls the heating power of the heating element to ensure that when the distance between the hair dryer and the target object changes, the temperature felt by the target object remains unchanged.

[0012] Preferably, the air nozzle is provided in a circular shape, a flat shape and a fan shape.

[0013] Preferably, the air nozzle is designed to be detachable from the hair dryer.

[0014] With the above solution, the hair dryer can achieve distance measurement and intelligent constant temperature control whether the air nozzle is installed or not.

[0015] Compared with the prior art, the present utility model has the following beneficial effects:

[0016] The distance sensor, the condenser lens and the air nozzle are coaxially arranged to ensure the accuracy and consistency of measurement. Using an infrared distance sensor or an optical distance sensor enables the device to adapt to different ranging requirements and environmental conditions, ensuring the accuracy and stability of measurement; the controller can automatically adjust the temperature of the heating element or the wind speed of the motor according to the data of the distance sensor, providing a more comfortable and personalized hair drying experience for users; by setting the condenser lens, distance measurement and intelligent constant temperature control can be achieved whether the air nozzle is installed or not.

[0026] Embodiment

[0027] As Figure 4 shown, the optical signal 7 emitted by the sensor transmitting end 21 of the distance sensor 2 of a conventional hair dryer is likely to hit the nozzle 8, and the nozzle 8 reflects the optical signal 7, which will cause the optical signal 7 received by the sensor receiving end 22 to come from different reflection points, ultimately resulting in the failure of distance measurement and affecting the temperature control of the hair dryer.

[0028] As Figures 1-3 shown, this embodiment provides a hair dryer distance measurement device, including a hair dryer, a nozzle 8 is provided at the front end of the hair dryer, a distance measurement component 1 is provided inside the hair dryer, the distance measurement component 1 includes a distance sensor 2 and a condensing lens 3, the distance measurement component 1 is arranged on the air outlet channel of the hair dryer, the condensing lens 3 is arranged in front of the distance sensor 2, and the distance sensor 2, the condensing lens 3 and the nozzle 8 are coaxially arranged.

[0029] Preferably, the distance sensor 2 is an infrared distance sensor or an optical distance sensor, which is used to improve the accuracy and stability of distance measurement.

[0030] Preferably, it further includes a heating element 4 and a controller 5, and the controller 5 is electrically connected to the heating element 4 and the distance sensor 2, which is used to realize automatic control and temperature adjustment.

[0031] Preferably, the controller 5 is further connected to an ambient temperature sensor 6, and the ambient temperature sensor 6 is electrically connected to the heating element 4. By providing the ambient temperature sensor 6, the controller 5 adjusts the heating power of the heating element 4 according to the data transmitted back by the distance sensor 2 and the ambient temperature sensor 6, so that the temperature felt by the human body is always maintained at a comfortable temperature.

[0032] Preferably, the nozzle 8 is provided in circular, flat and fan shapes. By providing various shapes of the nozzle 8, the blowing requirements of different users and scenarios can be met.

[0033] Working principle: When in use, the user selects a suitable shape of the nozzle 8 according to needs and installs it on the hair dryer. The user starts the hair dryer, and the distance sensor 2 starts to work to detect the distance between the hair dryer and the target object. As Figures 5-6 shown, the condenser lens 3 refracts the optical signal 7 emitted by the distance sensor 2, so that the optical signal 7 is concentrated within a relatively small angle range, and the optical signal 7 is more concentratedly irradiated on the target object. Subsequently, the distance sensor 2 receives the optical signal 7 reflected from the target object, calculates the distance between the hair dryer and the target object. At the same time, the motor 9 rotates, and the air under the grip is drawn into the air inlet under the grip. When the air flows through the ambient temperature sensor 6, the ambient temperature sensor 6 measures the temperature of the air. The controller 5 calculates the result of the temperature measurement and adjusts the power of the heating element 4 in real time according to the calculated result for temperature compensation, so that the temperature felt by the target object is not affected by the change in the position of the hair dryer, and to avoid scalding or other safety problems caused by excessive temperature.

Without departing from the spirit and essence of the present invention, those of ordinary skill in the art can make various equivalent modifications or substitutions to the embodiments of the present invention, and all such modifications or substitutions should be within the scope of the present invention. / Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
