Description

Technical Field

[0001] This utility model relates to the field of spray comb technology, and in particular to an infrared detection spray comb. Background Technology

[0002] In related technologies, spray combs typically have an infrared detector on the side with the comb teeth. During combing, the infrared detector detects hair and controls the spraying device accordingly. However, the inventors discovered during the actual research and development process that because the infrared detector is simply placed on the comb teeth, hair needs to be attached to the teeth for it to be detected. If the hair is thin or few in number, and only stays on the teeth without adhering to the comb surface, the infrared detector cannot effectively identify the hair, resulting in an ineffective spraying device and poor reliability.

[0003] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide an infrared detection spray comb that effectively solves the technical defect of unreliable use of spray combs in the existing technology.

[0012] Secondly, since the infrared transmitter and receiver are located near the ends of the comb teeth, even when the user is combing a small amount of hair or thin hair, the infrared transmitter and receiver can still identify it, which improves the sensitivity of the spray comb in identifying hair and further enhances the reliability of the spray comb.

[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0046] Please refer to the following: Figures 1 to 8 The infrared detection spray comb provided in several embodiments of this application will now be described. The infrared detection spray comb includes: a comb head 10 and a spray device 20.

[0047] The comb 10 has a comb tooth surface 11 with multiple comb teeth extending away from the end of the comb tooth surface 11. The comb tooth surface 11 has a spray outlet 12, which can output the atomized liquid generated by the spray device 20 to the outside so that the atomized liquid can be delivered to the hair when the spray comb is combing the hair. The comb tooth surface 11 is equipped with an infrared emitter 13 and an infrared receiver 14, which are used to identify hair and control the operation of the spray device 20. The distance between the infrared emitter 13 and the infrared receiver 14 and the comb tooth surface 11 is set to form a first height h1.

[0048] Specifically, by setting the distance between the infrared transmitter 13 and the infrared receiver 14 and the comb tooth surface 11, the infrared transmitter 13 and the infrared receiver 14 can be positioned close to the end of the comb teeth. When the user combs their hair, the infrared transmitter 13 and the infrared receiver 14 can identify the hair as long as it enters the comb teeth. Compared with the traditional method where the hair needs to be attached to the comb tooth surface 11 for the infrared detector to identify it, the reliability of the spray comb can be improved. At the same time, since the infrared transmitter 13 and the infrared receiver 14 are close to the end of the comb teeth, even when the user combs a small amount of hair or thin hair, the infrared transmitter 13 and the infrared receiver 14 can still identify it, which improves the sensitivity of the spray comb in identifying hair and further enhances the reliability of the spray comb.

[0049] Furthermore, since the infrared transmitter 13 and the infrared receiver 14 transmit and receive signals through a beam, they can monitor the number and thickness of hairs in real time, thereby enabling the spray device 20 to control the amount of atomized liquid output based on the number of hairs.

This structure can improve the installation yield of the first mounting protrusion 15 and the second mounting protrusion 16 and is less likely to cause the problem of reverse installation.

[0059] Specifically, the spray outlet 12 is a plurality of spray through holes or a plurality of spray through slots arranged at intervals along the front-back direction of the comb tooth surface 11. The comb tooth includes a plurality of heat-insulating comb teeth 19 and a plurality of heat-generating comb teeth 110, which are arranged alternately.
