[0035] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model is further described in detail below in combination with the drawings and examples.

[0036] Please refer to Figures 1 to 7 , the handle structure for the hair styling device provided by the embodiment of the present application will be described. The handle structure for the hair styling device comprises a handle shell 10 and a push rod 13.

[0037] The handle shell 10 is provided with an air inlet area at the rear end, and the air inlet area is provided with a switch assembly 11. The switch assembly 11 is used to control the opening or closing of the hair styling device. The push rod 13 is movably installed on the handle shell 10. The first free end of the push rod 13 extends forward and is provided with a switch acting protrusion 131. The second free end of the push rod 13 extends backward and is connected with the switch assembly 11.

[0038] Specifically, by arranging the switch assembly 11 at the air inlet area and arranging the switch acting protrusion 131 forward through the push rod 13, the switch acting protrusion 131 is arranged with a front and back spacing from the switch assembly 11. The defect that the switch assembly 11 invades the air duct 103 in the traditional technology can be solved, and the air speed and air volume of the air duct 103 are improved, so that the blowing effect can be further improved. By arranging the switch acting protrusion 131 forward through the push rod 13, the user can control the opening or closing of the hair styling device with one hand when holding the handle structure with one hand, and the user's convenience is improved.

[0039] In some embodiments of the present application, the handle shell 10 is provided with a limiting groove 104 extending forward and backward, and the push rod 13 is movably installed in the limiting groove 104. The second free end of the push rod 13 is provided with a first clamping groove 132 penetrating the upper and lower surfaces thereof, and the switch assembly 11 has a push button 111 extending upward and inserted into the first clamping groove 132. In this way, when the user controls the opening or closing of the hair styling device, the push rod 13 needs to be moved forward and backward by acting on the switch acting protrusion 131, so as to synchronously move the push button 111 of the switch assembly 11, thereby starting the switch assembly 11 to open or close, and further controlling the opening or closing of the hair styling device.

[0040] Specifically, the handle shell 10 is provided with a mounting site 105 at the air inlet area, and the mounting site 105 is provided with a first mounting cavity 1051, and the switch assembly 11 is fixedly installed in the first mounting cavity 1051. Preferably, the first mounting cavity 1051 in the mounting site 105 is upwardly open, so that when the external airflow enters the air inlet area, it will not blow into the first mounting cavity 1051, which is beneficial to reduce the noise.

[0041] Further, the handle shell 10 is provided with a plurality of support sites 106 at the air inlet area, and the mounting site 105 and the plurality of support sites 106 are arranged in a circular ring shape and surround the air inlet 101. One side of the mounting site 105 is provided with a wire outlet gap 1052, and the switch assembly 11 has a wire terminal 112 which can extend outwardly through the wire outlet gap 1052. The wire terminal 112 extending outwardly is connected to the control unit 18 of the hair styling device through a cable, so as to control the opening or closing of the hair styling device through the switch assembly 11.

[0042] More specifically, the support site 106 is detachably installed with an inner air inlet net 14, and the outer surface of the inner air inlet net 14 is covered with an outer air inlet net 15, and the inner air inlet net 14 is provided with a switch cover sheet 141 covering above the wire outlet gap 1052. By setting the switch cover sheet 141, the position of the wire terminal 112 of the switch assembly 11 can be shielded, so as to avoid the user from touching the live body, thereby improving the safety performance; and it can also prevent the wire terminal from falling off due to the external force acting on the outer air inlet net and the inner air inlet net, thereby further improving the reliability.

[0043] In some embodiments of the present application, the handle housing 10 comprises an upper housing 107 and a lower housing 108, which can be assembled to form an air duct 103 that penetrates through the front surface of the upper housing 107 and the lower housing 108 to form an air outlet 102, and is in communication with an air inlet 101 at the back. The air duct 103 is provided with a heating frame cover 16, a motor support 17 and a control unit 18, which are arranged in sequence from front to back. The axial space of the handle housing 10 can be fully utilized, thereby reducing the diameter of the handle housing 10 for the user to hold.

[0044] Specifically, the heating frame cover 16 is provided with a first passage 161 that penetrates through the front and back surfaces thereof, and a heating frame 162 is installed in the first passage 161; the motor support 17 is provided with a second passage 171 in which a motor assembly 172 is installed; and the control unit 18 is provided with a plurality of control buttons 181 exposed to the handle housing 10. The control unit 18 is connected with a first circuit board, and the control buttons 181 are integrated in the first circuit board and exposed to the handle housing 10, so that the user can trigger different working states of the hair styling device through the control buttons 181.

[0045] The hair styling device further comprises an accessory (not shown in the figure), which is a hair dryer, a hair dryer comb or a curling iron, and is connected with the handle housing 10, so that the air outlet 102 of the handle housing 10 can be in conductive connection with the air duct 103 of the accessory, so as to input the air flow of the handle housing 10 into the accessory to dry or style the hair. When the hair styling device is used, the user holds the handle housing 10, and then pushes the switch action protrusion 131 to displace the push rod 13, thereby driving the push button 111 of the switch assembly 11 to move to turn on or off the hair styling device; when the hair styling device is turned on, the hair styling device can be powered on, and the motor assembly 172 is started to work, so that the external air is input into the air duct 103 through the air inlet 101, and is blown into the accessory along the second passage 171 and the first passage 161 to the air outlet 102. The air flow blown out of the accessory can dry or style the hair.

[0046] More specifically, the upper housing and the lower housing can be assembled by mutual buckling, or can be assembled by buckling the upper housing and the lower housing with the heating frame cover 16 or the motor support 17, respectively. The outer surface of the upper housing and the lower housing is covered with an outer shell 109 to complete the assembly of the entire handle structure.

[0047] The above are only preferred embodiments of the present application, and only the technical principles of the present application are specifically described, and these descriptions are only for explaining the principles of the present application, and cannot be interpreted as limiting the protection scope of the present application in any way. Based on the explanation herein, any modification, equivalent replacement and improvement made within the spirit and principles of the present application, and other specific embodiments of the present application that can be conceived by those skilled in the art without creative labor, should be included in the protection scope of the present application.
