DETAILED DESCRIPTION

[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] As shown in Figures 1 to 3, the present invention discloses a device with hand drying and blowing functions, including a hair dryer 10 and a bracket assembly 20. The hair dryer 10 is electrically connected to a power source via a power cord 14 to ensure the normal operation of the hair dryer 10. The hair dryer 10 includes a connected air cylinder 11 and a handle 12. The front end of the air cylinder 11 is provided with an air outlet 16 and a first sensor 17. The first sensor 17 is used to identify a target object to be dried, such as a human hand or other object. The hair dryer 10 is provided with an air inlet 13, a switch 15, and a second sensor 18. A controller is provided in the hair dryer 10. Specifically, the air inlet 13 and the switch 15 are provided on the handle 12. A protective net is provided on the air inlet 13 to prevent hair or other objects from entering the hair dryer 10, thereby ensuring safety in use.

[0028] The bracket assembly 20 includes a bracket 24 and a positioning hole 21 and a trigger member 23 provided on the bracket 24. In this embodiment, the hair dryer 10 is removably inserted into the positioning hole 21 to position the hair dryer 10. The trigger member 23 cooperates with the second sensor 18 to detect whether the hair dryer 10 is properly installed on the bracket 24. The bracket 24 is a U-shaped plate. The side panels of the bracket 24 are provided with mounting holes for installing the bracket 24, and the bracket 24 is provided with a through hole for the power cord 14 to pass through.

[0029] The controller is electrically connected to the switch 15, the first sensor 17, and the second sensor 18. When the hair dryer 11 is inserted into the positioning hole 21, the trigger 23 triggers the second sensor 18 to operate, recognizing that the hair dryer 10 is properly installed. At the same time, the second sensor 18 transmits a signal to the controller, which controls the hair dryer 10 to operate in hand drying mode. When the first sensor 17 detects a hand or other object, the first sensor 17 transmits a signal to the controller, which controls the hair dryer 10 to operate and dry hands or other objects. The cooperation between the first sensor 17 and the second sensor 18 realizes the automatic hand drying function, eliminating the need for manual operation and improving safety and convenience.

[0030] In this embodiment, the first sensor 17 is located at the air outlet 16. The first sensor 17 is a pyroelectric sensor, an infrared sensor, or an ultrasonic sensor. The heat resistance temperature of the first sensor 17 is greater than the temperature of the hot air blown out of the air outlet 16, thereby ensuring the service life of the first sensor 17. Furthermore, the first sensor 17 is located at the air outlet 16, preferably at the center of the air outlet 16. Multiple air outlet holes are provided at the outer edge of the first sensor 17. The first sensor 17 is coaxial with the air outlet 16. The sensing area of ​​the first sensor 17 also serves as the air outlet area. After the first sensor 17 senses the target object, the air is directly discharged from the air outlet 16. This reasonable sensing area increases the effective area of ​​the first sensor 17 for identifying the target object, ensures the accuracy of target detection, and ensures the drying effect on human hands and other objects. This solves the problem in the prior art where the sensor for identifying the target object is placed on the bracket 24, resulting in only the side close to the hair dryer being the effective area of ​​the sensor, and the side away from the hair dryer being an ineffective area or a misjudgment area, thereby affecting the accuracy of the sensor detection results.

[0031] Specifically, the air duct 11 is an injection-molded part, a support plate is provided on the air outlet 16, the first sensor 17 is arranged at the center of the support plate, and a plurality of circumferentially arranged arc-shaped air outlet holes are provided on the support plate on the outer edge of the first sensor 17. Adjacent air outlet holes are connected by ribs, which can ensure a uniform air output from the air outlet 16 and ensure that the first sensor 17 accurately identifies human hands and other targets.

[0032] Optionally, a support block is provided on the inner wall of the air outlet 16 , and the first sensor 17 is arranged on the support block. The size of the support block is smaller than the size of the air outlet 16 to protect the air output of the air outlet 16 .

[0033] Optionally, the first sensor 17 may also be arranged on the outer wall of the air duct 11, and can also realize the function of identifying human hands and other objects.

[0034] Optionally, the hair dryer 10 is provided with a power supply battery to ensure normal use of the hair dryer 10 and improve the flexibility of use.

[0035] Optionally, a support net is provided at the air outlet 16, and a first sensor 17 is arranged at the center of the support net to ensure sufficient air output, improve the hand and hair drying effects, and prevent foreign objects from entering the air outlet 16, thereby ensuring normal use of the hair dryer 10.

[0036] The second sensor 18 is a Hall effect sensor, and the trigger 23 is a magnet. The Hall effect sensor and the magnet work together to identify the placement of the hair dryer 10 and switch the operating state of the hair dryer 10, ensuring that the hair dryer 10 is properly installed and can perform the hand drying function. This eliminates the need for a separate switch on the bracket 24 to identify the hair dryer 10, reducing the number of parts, making the structure more compact, and simplifying the control logic.

[0037] Furthermore, a positioning block 22 is provided on the bracket 24, and the handle 12 is detachably placed on the positioning block 22. The positioning block 22 positions the handle 12, making it easy to take and place the hair dryer 10, thereby improving the convenience of use.

[0038] There is one, two or more positioning blocks 22, and an arc-shaped groove for accommodating the handle 12 is provided on the positioning block 22. In this embodiment, there are two positioning blocks 22, and the two positioning blocks 22 are arranged along the length direction of the bracket 24. The arc-shaped groove structure ensures the stability of the placement of the handle 12 and prevents the handle 12 from sliding.

[0039] The positioning block 22 is made of rubber or plastic, which can position the handle 12 , reduce wear of the handle 12 , and increase the service life of the handle 12 .

[0040] The second sensor 18 is disposed on the handle 12, and the trigger member 23 is disposed within the arc-shaped groove of the positioning block 22. When the handle 12 is placed within the arc-shaped groove, the trigger member 23 simultaneously activates the second sensor 18. This provides a compact structure, saves installation space, and prevents accidental contact with the trigger member 23, thereby ensuring the accuracy of the detection results.

[0041] Optionally, a step is provided on the wind tube 11, the second sensor 18 is arranged on the step of the wind tube 11, and the trigger member 23 is arranged on the outer edge of the positioning hole 21. When the wind tube 11 is placed in the positioning hole 21, the trigger member 23 triggers the second sensor 18 to work.

[0042] Optionally, a second sensor 18 is provided on the outer wall of the hair dryer 11, and a trigger member 23 is provided on the bracket 24. When the handle 12 is inserted into the positioning hole 21, the trigger member 23 triggers the second sensor 18 to operate, and can also realize the identification of the placement status of the hair dryer 10. The air outlet 16 blows air in the horizontal direction to realize the function of drying hands.

[0043] Optionally, a protective net is provided on the air inlet 13, the air inlet 13 is arranged on the air cylinder 11, and the air inlet 13 is located at one end away from the air outlet 16, which can also realize the normal blowing function of the hair dryer 10.

[0044] Optionally, the switch 15 is provided on the hair dryer 11 , and can also realize the function of controlling the working state of the hair dryer 10 .

[0045] The working process of this utility model is as follows:

[0046] The hair dryer 10 is powered on. If the switch 15 is turned off, the hair dryer 10 is turned off.

[0047] When switch 15 is on:

[0048] (1) If the hair dryer 10 is not placed on the supporting bracket assembly, the trigger member 23 will not trigger the second sensor 18 to operate. At this time, the operation mode of the hair dryer 10 is the same as that of an existing hair dryer. The hair dryer 10 is started, and air enters from the air inlet 13 and is blown out from the air outlet 16, achieving a normal hair drying function;

[0049] (2) If the hair dryer 10 is placed on the matching bracket assembly, and the air cylinder 11 or the handle 12 is placed in the positioning hole 21, the trigger 23 triggers the second sensor 18 to work, and recognizes that the hair dryer 10 is installed in place. The second sensor 18 transmits a signal to the controller, and the controller controls the hair dryer 10 to enter the hand drying mode. At this time, the hair dryer 10 does not work. In order to further increase the stability of the installation of the hair dryer 10, the handle 12 can be placed on the positioning block 22. When a hand or other object is placed in the sensing area of ​​the first sensor 17, in this embodiment, the sensing area is the area in front of the air outlet 16 and within a range of 50 cm from the air outlet 16, the first sensor 17 detects the human hand or other object, and the first sensor 17 transmits a signal to the controller. The controller controls the hair dryer 10 to start, and air enters from the air inlet 13 and blows out from the air outlet 16, thereby achieving the function of drying hands or drying objects. If the hand or object is removed, the first sensor 17 cannot detect the human hand or object, and the controller controls the hair dryer 10 to turn off.

[0050] When the hair dryer 10 is removed from the matching bracket assembly, it can be used as a common hair dryer.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
