[0037] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] This invention relates to an automatic hair dryer fixing device, comprising a fixing base 100, a positioning mechanism 200, and an electrical control mechanism 300.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, the fixing base 100 can be box-shaped or frame-shaped, or other shapes. The fixing base 100 has a cavity 110. In this embodiment, the cavity 110 is a cylindrical through-hole opened vertically in the direction shown in the figure. A positioning mechanism 200 is mounted on the fixing base 100. The positioning mechanism 200 includes an electric drive component 210 and a moving component 220, with the electric drive component 210 connected to the moving component 220. The electric drive component 210 drives the moving component 220 to reciprocate relative to the cavity 110. During movement, the moving component 220 reciprocates radially along the cavity 110, meaning it can move towards the central axis of the cavity 110, which is taken as the forward direction; the moving component 220 can also move away from the central axis of the cavity 110, which is taken as the backward direction. The cavity 110 is used to receive foreign objects. When the moving member 220 moves forward and reaches the foreign object and can no longer advance, the electric drive member 210 will drive the moving member 220 to retreat a short distance, bringing it closer to the foreign object. A small gap is maintained between the moving member 220 and the foreign object; this gap can be, but is not limited to, 2mm. The electric drive member 210 is electrically connected to the electric control mechanism 300, which controls the start and stop of the electric drive member 210. The main body of the electric control mechanism 300 is a circuit board.

[0040] In this embodiment, the aforementioned external object can be an object capable of generating airflow, such as a hair dryer 700. The hair dryer 700 and the automatic hair dryer fixing device work together to form a combined hair dryer and hand dryer device. In actual use, initially, the moving part 220 retracts to an initial position away from the central axis of the cavity 110. For example... Figure 4As shown, the nozzle 710 of the hair dryer 700 is inserted into the cavity 110 from top to bottom. The electric drive unit 210 is activated, controlling the moving part 220 to move forward. The moving part 220 moves forward and abuts against the outer wall of the nozzle 710, pushing the nozzle 710 against the cavity wall of the cavity 110 until the outer wall of the nozzle 710 abuts against the cavity wall of the cavity 110, at which point the moving part 220 can no longer move forward. Then, the electric drive unit 210 drives the moving part 220 to move back a short distance, maintaining a certain gap between the moving part 220 and the outer wall of the nozzle 710, thus completing the positioning of the hair dryer 700. The other parts of the hair dryer 700 rest on the fixed base 100. The user can place their hands under the cavity 110 and use the hair dryer 700 to dry their hands.

[0041] The positioning mechanism 200 automatically adapts to the outer wall size of the object placed into the cavity 110, thus automatically positioning the object within the cavity 110 and accommodating objects of different sizes. The electric drive unit 210 automatically controls the retraction of the moving part 220, preventing excessive pressure on the object and potential damage. The retracted position keeps the object in a fixed position relative to the cavity 110 during use, preventing skew. Because the moving part 220 maintains a gap with the object during retraction, it does not clamp the object within the cavity 110, allowing the user to easily remove the object for individual use. For example, the hair dryer 700 in a hand dryer combo can be directly removed from the cavity 110 for drying hair, making it very convenient. After the object is removed from the cavity 110, the moving part 220 returns to its initial position, waiting for the object to be placed back into the cavity before repositioning.

[0042] The electric drive component 210 is preferably a motor, but can also be a cylinder, hydraulic cylinder, or other similar device. The telescopic movement of the electric drive component 210 can drive the translational movement of the moving component 220. In some embodiments, such as... Figure 2 , Figure 3 and Figure 5As shown, the electric drive component 210 is a motor. A connecting shaft 230 is mounted on the drive shaft 211 of the motor. When the motor rotates, it drives the connecting shaft 230 to rotate around its own axial direction. At least a portion of the movable component 220 is slidably connected to the fixed base 100. The movable component 220 and the connecting shaft 230 are connected by a thread. The threaded connection can be achieved by having a threaded hole inside the connecting shaft 230, or by having a nut inside the connecting shaft 230 and a stud on the movable component 220. When the motor rotates forward, driving the connecting shaft 230 to rotate, the fixed base 100 restricts the rotation of the movable component 220, causing relative rotation at the threaded connection between the connecting shaft 230 and the movable component 220. This pushes the movable component 220 to move linearly along the axial direction of the connecting shaft 230, thus converting the rotational motion of the connecting shaft 230 into the linear movement of the movable component 220. When the moving part 220 comes into contact with the object and cannot move forward, the torque of the motor gradually increases. For example, when the torque of the motor reaches 20N or other preset values, the motor stops rotating forward, and the moving part 220 stops moving forward. Then the motor reverses, rotating several times (the number of rotations is uncertain). If the threaded connection between the connecting shaft 230 and the moving part 220 is an M6 standard thread, without considering the deformation of the outer shell of the object, the motor drives the connecting shaft 230 to rotate in the opposite direction for 2 rotations, with a total thread pitch of 2mm. This ensures that there is a 2mm gap between the moving part 220 and the object after retraction, so that the relative position of the moving part 220 and the cavity 110 after adjustment is slightly larger than the outer diameter of the object. This completes the position adjustment.

[0043] Furthermore, such as Figure 2 and Figure 3 As shown, the fixed base 100 is provided with a guide groove 120. In this embodiment, the cavity 110 is vertically arranged, and foreign objects are inserted through the upper opening of the cavity 110. The guide groove 120 extends radially along the cavity 110 and communicates with the cavity 110. At least a portion of the movable member 220 is slidably mounted in the guide groove 120. When the connecting shaft 230 rotates, the threaded relative rotation between the movable member 220 and the connecting shaft 230 drives the movable member 220 to slide in the guide groove 120. The guide groove 120 restricts the rotation of the movable member 220 and guides its translation. The guide groove 120 is located near the upper opening of the cavity 110, and the positions of the positioning mechanism 200 and the movable member 220 are also located near the upper opening of the cavity 110. When an object is placed into the cavity 110, the moving part 220 is positioned above the part of the object placed into the cavity 110, which can prevent the object from tilting relative to the cavity 110 and keep the part of the object placed into the cavity 110 in a vertical position.

[0044] In some embodiments, such as Figure 1 , Figure 3 and Figure 5As shown, the movable component 220 can be configured as a block structure. The movable component 220 has a pressing surface 221 and a guide surface 222. The pressing surface 221 faces the central axis of the cavity 110. The pressing surface 221 is arc-shaped and mates with the outer wall of the hair dryer 700 when the external object is selected. The guide surface 222 is inclined and faces the upper opening of the cavity 110. When the external object is inserted into the cavity 110 from top to bottom, the external object may touch the upper part of the movable component 220. Through the inclination of the guide surface 222, the external object slides downward along the guide surface 222 into the cavity 110.

[0045] In some embodiments, such as Figure 1 and Figure 4 As shown, the fixed base 100 is also provided with a storage slot 130. The extension direction of the storage slot 130 is the same as the movement direction of the moving member 220. One end of the storage slot 130 is connected to an opening side of the cavity 110. In this embodiment, the movement direction of the moving member 220 is along the radial direction of the cavity 110, and the extension direction of the storage slot 130 is also correspondingly along the radial direction of the cavity 110. The storage slot 130 and the positioning mechanism 200 are located on both sides of the cavity 110, and one end of the storage slot 130 is opposite to the moving member 220. The part of the external object located outside the cavity 110 is placed in the storage slot 130, and the storage slot 130 is shaped to match it. When the external object is a hair dryer 700, the shape of the storage slot 130 is adapted to the shape of the handle part 720 of the hair dryer 700, and the handle part 720 is placed in the storage slot 130, using the storage slot 130 to position the external part of the hair dryer 700. The positions of the positioning mechanism 200 and the storage slot 130 ensure that when the moving member 220 pushes the air duct section 710 to position, the handle section 720 remains in the storage slot 130, preventing the handle section 720 from dislodging from the storage slot 130.

[0046] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a micro switch 400 is also installed on the mounting base 100. The micro switch 400 is electrically connected to the reactance mechanism. The button 410 of the micro switch 400 protrudes from below the storage slot 130 and extends into the storage slot 130. When the nozzle 710 of the hair dryer 700 is placed into the cavity 110, the handle 720 rests in the storage slot 130. Due to the weight of the hair dryer 700, the handle 720 presses down on the button 410 of the micro switch 400, triggering the micro switch 400. The micro switch 400 transmits a signal to the electronic control mechanism 300, which then controls the motor to start. When the hair dryer 700 is removed from the mounting base 100, the handle 720 moves away from the micro switch 400, and the button 410 of the micro switch 400 resets. The reset signal is fed back to the electronic control mechanism 300, which then controls the motor to start and drive the moving part 220 back to its initial position. The relative position setting of the storage slot 130 also ensures that when the positioning mechanism 200 positions the hair dryer 710, the handle 720 remains pressed down on the micro switch 400.

[0047] In some embodiments, such as Figure 1 and Figure 4 The mounting base 100 is also provided with a recess 140. The recess 140 is located at one end of the storage slot 130, which is away from the cavity 110. The wall of the recess 140 is connected to the end of the storage slot 130. The depth of the recess 140, that is, the bottom of the recess 140 is lower than the bottom of the storage slot 130. The handle 720 of the hair dryer 700 is placed in the storage slot 130, and one end of the handle 720 is located in the recess 140. The user can grab the handle 720 at the recess 140 to pull the hair dryer 700 away from the mounting base 100.

[0048] In some embodiments, such as Figure 1 and Figure 4 As shown, the mounting base 100 is also equipped with a shelf 150, which is integrally formed from the mounting base 100. The shelf 150 is frame-shaped and can hold items, such as the external nozzle 730 of the hair dryer 700. Before the hair dryer 700 is placed on the mounting base 100, the nozzle 730 can be removed and stored in the shelf 150.

[0049] In some embodiments, such as Figure 2 As shown, the mounting base 100 includes an upper cover 160 and a base 170. The upper cover 160 and the base 170 are connected vertically. A cylindrical portion 161 is provided on the upper cover 160. The cylindrical portion 161 extends from the upper cover 160 and is integrally formed. The cylindrical portion 161 may be a hollow cylindrical structure. The upper and lower ends of the cylindrical portion 161 are open. The interior of the cylindrical portion 161 forms a cavity 110.

[0050] In some embodiments, such asFigure 1 and Figure 6 As shown, the mounting base 100 is also equipped with an electrical socket 500 and a sensor 600. Both the electrical socket 500 and the sensor 600 are electrically connected to the electronic control mechanism 300. The plug of the hair dryer 700 is plugged into the electrical socket 500 for point detection. The sensor 600 can be an infrared sensor. The sensor 600 is located near the air outlet side of the cavity 110. In this embodiment, the hair dryer 700 blows air downwards, and the air outlet side of the cavity 110 is located at the bottom. When the user's hand is placed below the cavity 110, the sensor 600 senses the hand and feeds a signal back to the electronic control mechanism 300, which then controls the hair dryer 700 to be powered on to deliver air.
