Description

Technical Field

[0001] This utility model belongs to the field of household appliance technology, and in particular relates to an induction hair dryer. Background Technology

[0002] Hair dryers are primarily used for styling and drying hair and are widely used in people's daily lives. Current hair dryers typically use a power switch to turn the hair dryer on and off. Once the switch is pressed, the hair dryer remains in operation. However, users often repeatedly put the hair dryer down to free their hands while styling their hair, making it impossible for it to stop automatically when removed from their hands. Even when placed on a table or countertop, the hair dryer continues to operate. Prolonged continuous operation can easily cause the internal temperature to overheat and damage internal components. The high temperatures generated during operation can also potentially cause a fire, posing a significant safety hazard. Utility Model Content

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] like Figure 1-3 As shown in the figure, an embodiment of the present invention provides an induction hair dryer, including a hair dryer 1, a handle 2, and a power cord 3. The hair dryer 1 and the handle 2 are fixedly connected, and the hair dryer 1 and the handle 2 have a through air duct inside.

[0023] The air duct 1 includes an outer shell 11, a heating module 12, an intelligent control module 13, an intelligent control module bracket 14, and a back cover 15;

[0024] One end of the air duct housing 11 is an air outlet 16, and the other end of the air duct housing 11 is fixedly connected to the rear cover 15. The heating module 12 is fixedly installed in the air duct housing 11 on the side close to the air outlet 16. The intelligent control module bracket 14 is fixedly installed in the air duct housing 11 on the side away from the air outlet 16. The intelligent control module 13 is fixedly installed on the intelligent control module bracket 14. The rear cover 15 is provided with a touch display screen 151.

[0025] The handle 2 includes a handle housing 21, a single-button capacitive touch sensor chip 22, a motor 23, an inner bracket 24, and a copper sheet (not shown). The handle housing 21 is an insulator and includes an upper shell 211, an air inlet 212, and a bottom shell 213. The inner bracket 24 is fixed in the handle housing 21. The copper sheet (not shown) is fixed on the inner surface of the upper shell 211. The single-button capacitive touch sensor chip 22 is fixed on the side of the inner bracket 24 away from the bottom shell 213. The copper sheet 25 is electrically connected to the single-button capacitive touch sensor chip 22. The motor 23 is fixed on the side of the inner bracket 24 near the bottom shell 213.

[0026] The intelligent control module 13 is electrically connected to the heating module 12, the touch display screen 151, the motor 23 and the single-key capacitive touch sensing chip 22 respectively.

[0027] The bottom shell 213 has a hole (not shown) for the power cord 3 to pass through. The power cord 3 passes through the hole (not shown) and is electrically connected to the motor 23, the single-button capacitive touch sensing chip 22, the touch display screen 151, the intelligent control module bracket 14 and the heating module 12 respectively.

[0028] This invention relates to an inductive hair dryer that uses capacitive sensing technology. A copper sheet (not shown) is placed on the inner surface of the handle housing 21. A single-button capacitive touch sensor chip 22 and an intelligent control module 13 are fixed inside the hair dryer. The copper sheet (not shown) and the single-button capacitive touch sensor chip 22 are electrically connected, as are the single-button capacitive touch sensor chip 22 and the intelligent control module 13. When the hair dryer is held by a person, the person's hand and the copper sheet (not shown) form a capacitor. When the person puts down the hair dryer and removes their hand from the handle 2, the capacitance value of the capacitor changes. The intelligent control module 13 detects this capacitance value change through the single-button capacitive touch sensor chip 22 and controls the on / off state of the hair dryer, thereby realizing the function of stopping the hair dryer when the hand is removed. It is simple to operate, convenient to use, and can also avoid safety hazards.

[0029] like Figure 3 As shown, the bottom shell 213 is provided with a buckle (not shown) and at least two elastic limiting strips 2131.

The handle shell 21 is provided with a groove (not shown) that mates with the buckle (not shown) at the end near the bottom shell 213. The inner surface of the handle shell 21 is provided with a groove (not shown) that mates with the limiting strips 2131. A limiting block (not shown) that mates with the wedge-shaped limiting part (not shown) is provided at the end of the groove (not shown) near the bottom shell 213. The limiting strips 2133 can slide within the groove (not shown). The hair dryer is frequently in contact with... When the power cord 3 is being pulled, if the pulling force is too great, the power cord may be pulled off the handle body along with the bottom shell 213 of the handle 2, causing the power cord 3 to break. In this embodiment, a limiting strip 2131 and a limiting block (not shown) are provided. When the bottom shell 213 separates from the handle body of the handle 2 to a certain distance under the action of external force, the wedge-shaped limiting part (not shown) on the limiting strip 2131 will be stuck on the limiting block (not shown), preventing the bottom shell 213 and the handle body of the handle 2 from separating further, so that the bottom shell 213 and the power cord 3 will not be pulled further out of the handle body of the handle 2, thereby preventing the power cord 3 from being easily broken.

[0030] like Figure 3As shown, the outer surface of the inner bracket 24 is provided with an elastic protrusion 241. The inner bracket 24 is interference-fitted with the handle housing 21. This arrangement can make the inner bracket 24 more stably fixed in the handle housing 21.

[0031] like Figure 3 As shown, the air inlet 212 includes a hood 2121 and a filter 2122. The filter 2122 is fitted inside the hood 2121, which can filter out dust in the incoming air.

[0032] like Figure 3 As shown, a plastic protective shell 31 is fitted on the end of the power cord 3 that contacts the bottom shell 213. A limiting part 32 is provided on the power cord 3. The power cord 3 is fixed in the hole (not shown) through the limiting part 32. This arrangement can protect the part of the power cord 3 that contacts the bottom shell 213.

[0033] like Figure 2 As shown, a Bluetooth module 17 is also fixed inside the air duct 1. The Bluetooth module 17 is fixed between the smart control module 13 and the back cover 15. The Bluetooth module 17 is electrically connected to the smart control module 13, so that it can connect to a mobile phone via Bluetooth.

[0034] like Figure 2 As shown, the induction hair dryer of this utility model also includes a nozzle (not shown), which is connected to the end of the air outlet 16 of the air tube housing 11 by a magnetic or snap-fit ​​structure, which facilitates the connection between the nozzle and the air tube housing 11.

[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
