DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 In this embodiment, a portable hair dryer anti-misoperation and dust removal structure includes a hair dryer body 4, a handle 3 is provided on the lower surface of the hair dryer body 4, a charging port is opened on the lower surface of the handle 3, an anti-misoperation mechanism 1 is provided on the front of the handle 3 to prevent misoperation, and a dustproof mechanism 2 is provided inside the handle 3 to prevent dust from entering the charging port.

[0023] See also Figure 2 In order to prevent the temperature control button 109 from being pressed by mistake, the anti-mis-touch mechanism 1 in this embodiment includes a temperature control button 108 and a baffle 109 fixed on the front of the handle 3. Two limit rods 101 are fixed to the lower surface of the baffle 109. The bottom ends of the two limit rods 101 are fixed with limit plates 103. The upper surfaces of the two limit plates 103 are fixed with reset springs 105. The upper surfaces of the two reset springs 105 are fixed with fixed plates 107 slidably connected to the outer sides of the limit rods 101. The lower surfaces of the two fixed plates 107 are fixed with connecting plates 106. The two connecting plates The lower surface of 106 is fixed with an anti-mistaken touch box 102 that is in contact with the baffle 109. With the cooperation of the reset spring 105, the anti-mistaken touch box 102 can automatically return to the initial position after opening and fit together with the baffle 109 again to close the temperature control button 109. The bottom wall of the inner cavity of the anti-mistaken touch box 102 is fixed with a magnet 104 that is magnetically attracted to the lower surface of the limit plate 103. The magnet 104 magnetically attracts the limit plate 103 so that the anti-mistaken touch box 102 cannot move further after returning to the initial position, thereby preventing the anti-mistaken touch box 102 from continuously shaking under the elastic potential energy of the reset spring 105.

[0024] The anti-false touch box 102 is in the shape of a rectangular parallelepiped with a hollow interior and a missing upper surface. Rubber pads are fixed to the back and upper surfaces of the anti-false touch box 102. The rubber pads on the back of the anti-false touch box 102 reduce the random up and down shaking of the anti-false touch box 102. At the same time, the rubber pads on the upper surface of the anti-false touch box 102 prevent the baffle 109 and the anti-false touch box 102 from directly colliding. A limiting hole for the limiting rod 101 to pass through is provided on the upper surface of the fixing plate 107, and the limiting rod 101 is slidably connected to the fixing plate 107 through the limiting hole. The two limiting plates 103 are fixed to the front of the dustproof mechanism 2 and are located inside the anti-false touch box 102. The reset spring 105 is located on the outside of the limiting rod 101.

[0025] It can be seen that the anti-mistaken touch mechanism 1 protects the temperature control button 108 through the cooperation of the limit rod 101, the anti-mistaken touch box 102, the limit plate 103, the magnet 104, the reset spring 105, the connecting plate 106, the fixing plate 107 and the baffle 109, so as to prevent the temperature control button 108 from being accidentally pressed when the handle 3 of the hair dryer is used, causing the hair dryer to be turned off or the temperature to be adjusted.

[0026] See also Figure 3In order to prevent dust from entering the charging port, the dustproof mechanism 2 in this embodiment includes a fixed rod 203 fixed inside the dustproof mechanism 2, a positioning block 206 is slidably connected to the outer side of the fixed rod 203, a positioning spring 204 located on the outer side of the fixed rod 203 is fixed to the left side of the positioning block 206, a dustproof cover 205 is fixed to the lower surface of the positioning block 206, a limit spring 201 is fixed to the top wall of the inner cavity of the handle 3, and a limit block 202 is fixed to the lower surface of the limit spring 201.

[0027] A limiting groove for the limiting block 202 to be inserted is provided on the upper surface of the positioning block 206, and the shape of the lower surface of the limiting block 202 is semicircular, and a fixing hole for the fixing rod 203 to pass through is provided on the left side of the positioning block 206, and the fixing rod 203 is loosely matched with the positioning block 206 through the fixing hole. After the limiting block 202 is aligned with the limiting groove on the positioning block 206, the limiting spring 201 pushes the limiting block 202 downward through the rebound force so that the limiting block 202 is inserted into the positioning block 206 to limit the movement of the positioning block 206, thereby limiting the movement of the dust cover 205, and further making the dust cover 205 not automatically close for a long time after being opened, so that the charging cable can be inserted into the charging port for long-term charging.

[0028] Therefore, the dustproof mechanism 2 closes the charging port on the lower side of the handle 3 through the cooperation of the fixing rod 203, the positioning spring 204, the dustproof cover 205 and the positioning block 206, so as to prevent dust from entering the charging port when not in use, resulting in poor contact caused by dust obstruction during subsequent use, causing the hair dryer to fail to charge. At the same time, the cooperation of the limit spring 201 and the limit block 202 makes it convenient to open the dustproof cover 205 to use the charging port.

[0029] The working principle of the above embodiment is:

[0030] (1) When the temperature control button 108 is needed to turn on the hair dryer or adjust the temperature of the hair dryer, the anti-false touch box 102 is pressed and pushed downward. The anti-false touch box 102 drives the fixing plate 107 to move downward through the connecting plate 106. The fixing plate 107 compresses the reset spring 105 while moving downward and slides on the outside of the limit rod 101. At the same time, the limit plate 103 separates from the magnet 104. When the reset spring 105 is compressed to the shortest, the anti-false touch box 102 is fully opened. At this time, the temperature control button 108 can be used. After use, release the anti-false touch box 102. The reset spring 105 is released. The rebound force pushes the fixed plate 107 upward, thereby driving the anti-false touch box 102 to move upward through the connecting plate 106 until it fits with the baffle 109, and makes the limit plate 103 and the magnet 104 adsorbed together to close the anti-false touch box 102. The anti-false touch mechanism 1 protects the temperature control button 108 through the cooperation of the limit rod 101, the anti-false touch box 102, the limit plate 103, the magnet 104, the return spring 105, the connecting plate 106, the fixed plate 107 and the baffle 109, so as to avoid accidentally pressing the temperature control button 108 when holding the handle 3 of the hair dryer when using the hair dryer, causing the hair dryer to be turned off or the temperature to be adjusted.

[0031] (2) When the hair dryer needs to be charged, the charging head needs to be inserted into the charging port at the bottom of the handle 3. First, the dust cover 205 is pushed to the left. The dust cover 205 drives the positioning block 206 to move to the left, and the positioning block 206 compresses the positioning spring 204. At the same time, the positioning block 206 slides on the outside of the fixed rod 203. When the limit block 202 is inserted into the interior of the positioning block 206, the dust cover 205 is loosened. At this time, the charging port line can be connected to the charging line for charging. The dustproof mechanism 2 closes the charging port on the lower side of the handle 3 through the cooperation of the fixed rod 203, the positioning spring 204, the dust cover 205 and the positioning block 206, so as to prevent dust from entering the charging port when the charging port is not in use, resulting in poor contact due to dust obstruction during subsequent use, causing the hair dryer to fail to charge. At the same time, the cooperation of the limit spring 201 and the limit block 202 facilitates the opening of the dust cover 205 to use the charging port.
