DETAILED DESCRIPTION

[0039] The following will be described in detail below with reference to the accompanying drawings. Figures 1-9 The present application is further described in detail.

[0040] The embodiment of the present application discloses a heating hair dryer.

[0041] Referring to Figure 1 and Figure 2 , the heating hair dryer comprises a first hair clip plate 1 and a second hair clip plate 2, and the tail end of the first hair clip plate 1 and the tail end of the second hair clip plate 2 are rotationally connected. The second hair clip plate 2 has a clamping state and an unfolded state, when the second hair clip plate 2 is in the clamping state, the front end of the second hair clip plate 2 abuts against the front end of the first hair clip plate 1; when the second hair clip plate 2 is in the unfolded state, the front end of the second hair clip plate 2 is separated from the front end of the first hair clip plate 1.

[0042] Referring to Figure 3 and Figure 4 , the first hair clip plate 1 comprises an outer shell 11 and an inner shell 12 arranged inside the outer shell 11. The tail end of the inner shell 12 is provided with an air inlet 121, and the front end of the inner shell 11 is provided with an air outlet 122. The inner shell 12 has a mounting chamber 123, and the mounting chamber 123 comprises a first cavity 1231 close to the side of the air outlet 122 and a second cavity 1232 close to the side of the air inlet 121.

[0043] Referring to Figure 3 and Figure 4 , a high-speed fan 3 is installed in the first cavity 1231, and a control board 4 matched with the high-speed fan 3 is installed in the second cavity 1232. Wherein, the fan blade of the high-speed fan 3 is arranged towards one side of the control board 4, and the blowing direction of the high-speed fan 3 is from the second cavity 1232 to the first cavity 1231.

[0044] Referring to Figure 1 and Figure 3, the first hair clip plate 1 is provided with an air inlet structure communicated with the second cavity 1232. The air inlet structure includes an air inlet through groove 124 opened in the inner shell 12 towards the side of the second hair clip plate 2 and an air inlet through hole 111 provided in the outer shell 11 opposite to the air inlet through groove 124. The air inlet through groove 124 is arranged opposite to the control panel 4, and there is a certain distance between the air inlet through groove 124 and the control panel 4, so that the airflow can enter the first cavity 1231 from the air inlet through groove 124. The air inlet through hole 111 is an array of through hole structures arranged on the outer shell 11. The diameter of the air inlet through hole 111 is 0.5mm to 1.5mm, so that the airflow can flow to the air inlet through groove 124 through the air inlet through hole 111 while reducing the probability of impurities entering the second cavity 1232. Wherein, when the second hair clip plate 2 is in the clamping state, the first hair clip plate 11 and the second hair clip plate 2 form an air inlet gap for the airflow to enter the air inlet structure.

[0045] Referring to Figure 3 and Figure 5 , the inner shell 12 is provided with a plurality of parallel arranged abutting convex edges 125 on the inner wall of the side of the inner shell 12 towards the second hair clip plate 2 and on both sides of the air inlet through groove 124 along the length direction, and a arrangement groove 126 is formed between adjacent two abutting convex edges 125. A plurality of ventilation grooves 1261 penetrating the upper and lower surfaces and communicated with the second cavity 1232 are opened at the groove bottom of each arrangement groove 126 along the length direction, so that when the airflow enters from the air inlet 121 at the tail end of the inner shell 12, part of the airflow can enter the ventilation groove 1261 along the arrangement groove 126 and then enter the second cavity 1232. Wherein, part of the airflow entering the inside of the outer shell 11 from the air inlet through hole 111 can also enter the ventilation groove 1261 along the arrangement groove 126 and then enter the second cavity 1232. Thus, the air inlet amount of the second cavity 1232 can be increased.

[0046] Referring to Figure 6 , the inner shell 12 is provided with a dust screen 5 arranged opposite to the high-speed fan 3 at the connection between the first cavity 1231 and the second cavity 1232. Wherein, the side wall of the inner shell 12 is circumferentially provided with a clamping ring groove 127, and the dust screen 5 is installed in the clamping ring groove 127 to realize the clamping fixation of the dust screen 5. The middle part of the dust screen 5 is provided with a flow guide through hole 51 opposite to the motor of the high-speed fan 3, and the diameter of the flow guide through hole 51 is smaller than the diameter of the motor of the high-speed fan 3, so that the mesh area of the dust screen 5 is opposite to the blade area of the high-speed fan 3. When the airflow flows from the second cavity to the high-speed fan 3, the dust screen 5 can reduce the impurities such as hair entering the blade area of the high-speed fan 3.

[0047] Referring to Figure 1 and Figure 7, in order to enable the second hair clip plate 2 to be kept in the clamping state, a buckle structure is arranged between the first hair clip plate 1 and the second hair clip plate 2. The buckle structure comprises a sliding buckle 6 slidingly arranged on the second hair clip plate 2, a reset spring 7 abutting against the inner wall of the second hair clip plate 2 at one end and abutting against the sliding buckle 6 at the other end away from the tail end of the second hair clip plate 2, and a clamping groove 112 arranged in the outer shell 11 towards the front end.

[0048] With reference to Figure 7 and Figure 8 , the sliding buckle 6 comprises a sliding portion 61 slidingly arranged in the second hair clip plate 2, a push-pull portion 62 arranged in the sliding portion 61 away from the first hair clip plate 1 and close to the tail end of the second hair clip plate 2, and a hook-shaped portion 63 arranged in the sliding portion 61 close to the first hair clip plate 1 and away from the tail end of the second hair clip plate 2. The second hair clip plate 2 is provided with a sliding groove 21 on the side away from the first hair clip plate 1 for the sliding of the push-pull portion 62. Before the front ends of the first hair clip plate 1 and the second hair clip plate 2 abut against each other, the push-pull portion 62 is pushed towards the direction of the front end of the second hair clip plate 2, so that the reset spring 7 is compressed. When the front end of the first hair clip plate 1 and the front end of the second hair clip plate 2 abut against each other, the push-pull portion 62 is released, and the reset spring 7 can push the hook-shaped portion 63 towards the direction of the clamping groove 112, so that the bottom end of the hook-shaped portion 63 is clamped into the clamping groove 112, thereby enabling the second hair clip plate 2 to be kept in the clamping state.

[0049] With reference to Figure 9 , the tail end of the first hair clip plate 1 and the tail end of the second hair clip plate 2 are further provided with an abutting spring 8, which can drive the second hair clip plate 2 to always have a tendency to be in the unfolded state, so as to facilitate the rotation of the second hair clip plate 2 relative to the first hair clip plate 1.
