Technical Field
[0001] This utility model relates to the field of high-speed hair dryer technology, specifically a high-speed hair dryer and its TOF sensor structure. Background Technology
[0002] High-speed hair dryers have multiple safety protection measures. They are usually equipped with NTC temperature control technology, which uses a built-in real-time temperature control sensor chip to monitor the temperature of the air outlet and ensure it is within a safe range, thus avoiding damage to the hair and scalp from high temperatures. High-speed hair dryers usually have a constant temperature control function, which can maintain the air temperature at around 60℃, avoiding the critical temperature that damages the hair cuticle.
[0003] A high-speed hair dryer, as disclosed in Chinese Utility Model Patent Publication No. CN219699274U, includes a hair dryer body. A head assembly is detachably mounted on one side of the hair dryer body, and a motor body is fixedly mounted on the end of the head assembly away from the hair dryer body. The head assembly includes an inner shell on a handle, within which a central air duct is formed. Two connecting keys are symmetrically arranged on the outer edge of the inner shell facing the head assembly. Connecting seats for the connecting keys are formed on both sides of the head assembly. An annular groove is formed on the outer edge of the inner shell facing the head assembly, and an O-ring seal is movably disposed within the annular groove. This high-speed hair dryer, through its closed design, forms a fully enclosed, seamless air duct, significantly reducing airflow loss, lowering manufacturing costs, simplifying assembly, and enhancing practicality.
[0004] However, if a high-speed hair dryer is left stationary on a table or bed for an extended period of time while operating at high speed and high heat, it may cause a safety hazard. This not only poses a safety risk but also affects the performance of the high-speed hair dryer. Utility Model Content

[0009] Preferably, the side of the arc-shaped block furthest from the accelerometer has a V-shaped structure.

[0012] Preferably, the arc-shaped limiting block has an M-shaped structure on the side away from the spring, and the arc-shaped limiting block is in contact with the inner wall of the limiting groove.
[0013] In addition, this application also relates to a high-speed hair dryer TOF sensor structure.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This utility model uses an accelerometer sensor to detect when the high-speed hair dryer is held still or placed flat on a table.

[0016] 2. This utility model, by setting a positioning component, allows the receiving block to be inserted into the receiving groove after the handle is disassembled, and the arc-shaped fixed block to slide in the horizontal groove of the positioning groove until the end face of the receiving block contacts the inner side wall of the receiving groove. At this time, the arc-shaped fixed block slides to the intersection of the positioning groove.

[0017] 3. By setting a limiting component, when the arc-shaped block slides in the vertical groove of the positioning groove, the inclined surface of the V-shaped end of the arc-shaped block will press against the inclined surface of the M-shaped end of the arc-shaped limiting block, causing the arc-shaped limiting block to slide in the limiting groove. This causes the spring to contract under force until the side of the arc-shaped block contacts the inner wall of the vertical groove of the positioning groove. At this time, under the action of the spring, the V-shaped end of the arc-shaped block will contact the M-shaped end of the arc-shaped limiting block, fixing the position of the arc-shaped block in the positioning groove, thereby improving the stability of the accelerometer position.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

The core, an MCU chip with a maximum operating frequency of 128MHz, implements software high-frequency conversion technology to drive high-power transistors, thereby controlling the high-speed operation of the matching BLDC motor.

Equipped with a high-speed motor, the rotation speed can reach up to 108,000 revolutions per minute, and it can spray a powerful airflow of 60m / s, saving time. It can achieve a low-temperature quick-drying effect, bringing efficient, smooth, and gentle hair drying results from the fundamental performance.

The control system enables the intelligent hair dryer to switch between multiple speeds, multiple temperatures, and intelligent hot and cold alternation modes, as well as various abnormal alarm and protection functions.
[0026] This invention uses an accelerometer 2 to sense when the high-speed hair dryer body 1 is held still or placed flat on a table. It automatically switches to a low-power mode, illuminates the indicator light 104, and disconnects the heating element to protect itself and prevent accidents. Shaking the high-speed hair dryer body 1 will automatically return it to the sensing mode.
[0027] As a preferred embodiment, the positioning component 3 includes a fixed base 301, a receiving groove 302, a receiving block 303, a positioning groove 304, and an arc-shaped fixing block 305; the fixed base 301 is fixedly connected to the inner wall of the handle 102; the fixed base 301 has a receiving groove 302 on the side near the accelerometer 2; the receiving block 303 is inserted into the receiving groove 302 and fixedly connected to the accelerometer 2; three positioning grooves 304 are arranged in a circular array in the receiving groove 302; the arc-shaped fixing block 305 slides through the positioning groove 304 and is fixedly connected to the circumferential surface of the receiving block 303; the positioning groove 304 has an L-shaped structure, and the size of the positioning groove 304 on the side near the accelerometer 2 is smaller than the size of the positioning groove 304 on the side away from the accelerometer 2; the arc-shaped fixing block 305 has a V-shaped structure on the side away from the accelerometer 2.
[0028] This utility model, by setting a positioning component 3, allows the receiving block 303 to be inserted into the receiving groove 302 after the handle 102 is disassembled, and the arc-shaped fixing block 305 to slide in the horizontal groove of the positioning groove 304 until the end face of the receiving block 303 contacts the inner side wall of the receiving groove 302. At this time, the arc-shaped fixing block 305 slides to the intersection of the positioning groove 304. Then, the acceleration sensor 2 is rotated to make the receiving block 303 rotate in the receiving groove 302, and the arc-shaped fixing block 305 slides in the vertical groove of the positioning groove 304 until the side of the arc-shaped fixing block 305 contacts the inner side wall of the vertical groove of the positioning groove 304.
[0029] As a preferred embodiment, it also includes a limiting component 4; the limiting component 4 is arranged in the positioning groove 304; the limiting component 4 includes a limiting groove 401, an arc-shaped limiting block 402 and a spring 403; the positioning groove 401 is provided in the positioning groove 304; the arc-shaped limiting block 402 slides through the limiting groove 401 and is inserted into the arc-shaped fixed block 305; both ends of the spring 403 are fixedly connected to the limiting groove 401 and the arc-shaped limiting block 402 respectively; the side of the arc-shaped limiting block 402 away from the spring 403 has an M-shaped structure, and the arc-shaped limiting block 402 contacts the inner wall of the limiting groove 401; the size of the M-shaped end of the arc-shaped limiting block 402 is smaller than the size of the V-shaped end of the arc-shaped fixed block 305.
[0030] By setting a limiting component 4, when the arc-shaped fixed block 305 slides in the vertical groove of the positioning groove 304, the inclined surface of the V-shaped end of the arc-shaped fixed block 305 will press against the inclined surface of the M-shaped end of the arc-shaped limiting block 402, causing the arc-shaped limiting block 402 to slide in the limiting groove 401. This causes the spring 403 to contract under force until the side of the arc-shaped fixed block 305 contacts the inner sidewall of the vertical groove of the positioning groove 304. At this time, under the action of the spring 403, the V-shaped end of the arc-shaped fixed block 305 will contact the M-shaped end of the arc-shaped limiting block 402, fixing the position of the arc-shaped fixed block 305 in the positioning groove 304, thereby improving the stability of the position of the acceleration sensor 2.
[0031] In addition, this application also relates to a high-speed hair dryer TOF sensor structure.
[0032] Working principle: Using accelerometer 2, the high-speed hair dryer body 1 is automatically switched to a low-power static mode when held still or placed flat on a table, based on gravity sensing. This mode illuminates indicator light 104 and disconnects the heating element, providing protection and effectively preventing accidents. Shaking the hair dryer body 1 automatically returns it to the sensing mode. When installing accelerometer 2, after disassembling the handle 102, the receiving block 303 is inserted into the receiving groove 302, and the arc-shaped fixing block 305 slides within the horizontal groove of the positioning groove 304 until the end face of the receiving block 303 contacts the inner wall of the receiving groove 302. At this point, the arc-shaped fixing block 305 slides to the intersection of the positioning groove 304. Rotating accelerometer 2 then causes the receiving block 303 to rotate within the receiving groove 302. The arc-shaped fixed block 305 slides within the vertical groove of the positioning groove 304, causing the V-shaped inclined surface of the arc-shaped fixed block 305 to press against the M-shaped inclined surface of the arc-shaped limiting block 402. This causes the arc-shaped limiting block 402 to slide within the limiting groove 401, resulting in the spring 403 being compressed until the side of the arc-shaped fixed block 305 contacts the inner wall of the vertical groove of the positioning groove 304. At this point, under the action of the spring 403, the V-shaped end of the arc-shaped fixed block 305 will contact the M-shaped end of the arc-shaped limiting block 402. During disassembly, the acceleration sensor 2 is rotated in the opposite direction to prevent the V-shaped end of the arc-shaped fixed block 305 from contacting the M-shaped end of the arc-shaped limiting block 402, and the arc-shaped fixed block 305 slides to the intersection of the positioning groove 304. Then, the acceleration sensor 2 is moved in the opposite direction until the receiving block 303 is moved out of the receiving groove 302.
