Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a clamping and swinging device for a hair dryer. Background Art

[0002] At present, since a hand-held hair dryer needs to be held up for a long time during use, it often causes fatigue of the user's arm. To solve this problem, a swinging bracket for a hair dryer has been introduced in the market, which can swing the hair dryer left and right, thus liberating the user's hands. Generally, such a swinging bracket fixes the hair dryer through a special mounting base and is equipped with a driving device to realize the swinging function of the hair dryer. However, there are some problems in the structure of the existing hair dryer swinging brackets in the market: First, since the driving device is usually installed on one side of the mounting base of the hair dryer, the weight of the upper end of the bracket is too large, which to a certain extent limits the length of the bracket. Because once the bracket is too long, the center of gravity of the whole device will be unstable, which is likely to cause safety problems. Second, if the driving device is installed on the base, the torque requirement for the motor is extremely high, and the motor needs to have enough torque to drive the whole bracket to rotate. This usually requires an AC motor with a relatively high cost, which undoubtedly increases the production cost. Therefore, it is necessary to develop a clamping and swinging device for a hair dryer, which can install a DC motor with low torque on the base and realize the swinging function of the bracket.

[0023] The following will describe in detail the implementation manners of the present utility model with reference to the accompanying drawings.

[0024] As Figures 1-4 shown, a clamping and swinging device for a hair dryer includes a support rod 2, a base 1 connected to one end of the support rod 2, and a fixed seat 3 connected to the other end of the support rod 2. The base 1 includes a second cover plate 12, a first cover plate 11 that can rotate relative to the second cover plate 12, and a DC drive assembly 13 respectively connected to the first cover plate 11 and the second cover plate 12. The first cover plate 11 is provided with a sliding assembly 112 connected to the second cover plate 12. The DC drive assembly 13 includes a torque amplifier 133 for increasing the torque of the DC drive assembly 13. The support rod 2 is connected to the first cover plate 11. When the base 1 abuts against the horizontal plane, the DC drive assembly 13 drives the first cover plate 11 to swing relative to the second cover plate 12 through the sliding assembly 112, so that the support rod 2 drives the hair dryer fixed on the fixed seat 3 to swing.

[0025] By adding a torque amplifier 133 to the DC drive assembly 13 in the present utility model, the low-torque driver 131 can generate sufficient torque to drive the entire bracket to rotate, effectively solving the problem of the high-torque requirement of the traditional swinging bracket for the motor. At the same time, by providing a sliding assembly 112 on the first cover plate 11, when the DC drive assembly 13 drives the first cover plate 11 to rotate relative to the second cover plate 12, the friction between the first cover plate 11 and the second cover plate 12 can be reduced, thereby driving the fixed seat 3 to swing, effectively reducing the requirement for high torque of the motor.

[0026] Specifically, in the present utility model, a torque amplifier 133 is added to the DC drive assembly 13. By optimizing the motor output, the torque amplifier 133 amplifies the relatively small motor torque, enabling the low-torque driver 131 to generate sufficient torque to drive the entire bracket to rotate. Thus, the problem of the traditional swing bracket's high torque requirement for the motor is effectively solved. This setting not only improves the performance of the device but also reduces the dependence on high-power motors, saving costs and energy. Further, by providing a sliding assembly 112 on the first cover plate 11, when the DC drive assembly 13 drives the first cover plate 11 to rotate relative to the second cover plate 12, the sliding assembly 112 can reduce the friction between the first cover plate 11 and the second cover plate 12, thereby achieving smooth movement between the first cover plate 11 and the second cover plate 12. This setting not only improves the operating efficiency of the device but also reduces the wear caused by friction, extending the service life of the device. Further, the setting of the sliding assembly 112 makes the movement of the first cover plate 11 smoother, further reducing the requirement for high motor torque, reducing energy consumption, and improving the economy of the device. Further, the low-torque driver is a DC motor, and this setting effectively reduces the production cost by using a low-torque DC motor to replace the relatively expensive AC motor.

[0027] Further, as Figures 2-4 shown in a clamping and swinging device for a blowing device, wherein the DC drive assembly 13 further includes a low-torque driver 131 and a connecting rod assembly 132 respectively connected to the torque amplifier 133. The first cover plate 11 is provided with a first inner cavity 111 and a first fixed end 113 located in the first inner cavity 111. The second cover plate 12 is provided with a second cover plate surface 125 and a limiting end 121 extending from the second cover plate surface 125 towards the first cover plate 11. The limiting end 121 and the second cover plate surface 125 enclose a second inner cavity 122. The second inner cavity 122 is provided with a connecting end 123. The first fixed end 113 is cooperatively connected with the low-torque driver 131, and the connecting end 123 is cooperatively connected with the connecting rod assembly 132, so that the DC drive assembly 13 is connected to the first cover plate 11 and the second cover plate 12.

[0028] The utility model adopts the cooperative connection between the first fixed end 113 and the low-torque driver 131, so that the low-torque driver 131 can be stably fixed in the first cover plate 11, avoiding the problem of loosening of the low-torque driver 131 due to vibration or external force, thereby improving the overall stability and reliability of the device; further, the cooperative connection between the connection end 123 and the connecting rod assembly 132 enables the DC drive assembly 13 to effectively transmit torque to the second cover plate 12 through the connecting rod assembly 132, realizing a large swing movement of the blowing device; further, the first cover plate 11 is provided with a first inner cavity 111 and the second cover plate 12 is provided with a second inner cavity 122, which not only provides sufficient installation space for the DC drive assembly 13, but also provides an operating space for the movement of the connecting rod assembly 132.

[0029] Further, as Figures 2-4 shown in a clamping and swinging device of a blowing device, wherein the torque amplifier 133 is provided with an eccentric shaft, the connecting rod assembly 132 includes a second connecting rod 1322, a first connecting rod 1321 connected to one end of the second connecting rod 1322, and a third connecting rod 1323 connected to the other end of the second connecting rod 1322. One end of the first connecting rod 1321 is connected to the eccentric shaft, a positioning portion 13231 is provided at the end of the third connecting rod 1323 away from the second connecting rod 1322, a plurality of uniformly distributed positioning steps 13232 are provided on one side of the positioning portion 13231, and a plurality of uniformly distributed positioning grooves 1231 are provided on the connection end 123. The positioning steps 13232 cooperate with the positioning grooves 1231 to enable the DC drive assembly 13 to cooperate with the second cover plate 12.

[0030] In the utility model, an eccentric shaft is provided on the torque amplifier 133 and the eccentric shaft is connected to the connecting rod assembly 132. This setting enables the rotation of the eccentric shaft to be converted into a more stable and large swing through a multi-link structure; further, a plurality of positioning steps 13232 are provided on the positioning portion 13231 to cooperate with a plurality of positioning grooves 1231 on the connection end 123. This setting not only improves the stability and reliability of the connection between the DC drive assembly 13 and the second cover plate 12, but also enables the device to maintain high-precision positioning during operation, thereby reducing the problem of displacement error caused by vibration during movement.

[0031] Further, as Figure 3 shown in a clamping and swinging device of a blowing device, wherein the first fixed end 113 includes a connecting rod 1131 and a fixed cavity 1132. The torque amplifier 133 extends out of the matching ends on both sides. The low-torque driver 131 is fixed in the fixed cavity 1132, and the matching ends cooperate with the connecting rod 1131 to enable the DC drive assembly 13 to be cooperatively connected with the first cover plate 11.

[0032] In the present utility model, by providing a fixing cavity 1132 for fixing the low-torque driver 131 in the first inner cavity 111, this arrangement ensures the effective positioning of the low-torque driver 131 during the operation of the device, guaranteeing that the low-torque driver 131 will not be displaced due to vibration or external forces, thereby improving the stability and reliability of the device; further, the mating end is preferably connected to the connecting rod 1131 by a threaded manner, ensuring that the DC drive assembly 13 can be firmly connected to the first cover plate 11, and at the same time making the assembly and disassembly of the DC drive assembly 13 more convenient, improving the assembly and maintenance efficiency.

[0033] Further, as Figures 1-3 shown in a clamping and swinging device of a blowing device, wherein the first inner cavity 111 further has a second fixed end 115, the second fixed end 115 is provided with a fixing hole 1151, and the support rod 2 is cooperatively connected with the first cover plate 11 through the fixing hole 1151.

[0034] In the present utility model, by providing the fixing hole 1151 for fixing the support rod 2 on the second fixed end 115, this arrangement enhances the connection stability between the support rod 2 and the first cover plate 11; further, the second fixed end 115 is arranged in the first inner cavity 111, so that the fixing hole 1151 has sufficient depth for inserting the support rod 2, providing sufficient guidance to ensure the direction of the support rod 2, effectively avoiding the situation of instability or shaking of the support rod 2 during operation.

[0035] Further, as Figures 1-3 shown in a clamping and swinging device of a blowing device, wherein the base 1 further includes a pressing plate 14, a first avoidance hole 13233 is provided in the middle of the positioning portion 13231, a second avoidance hole 126 is further provided on the other side of the connecting end 123 where the second cover plate 12 is located, a third avoidance hole 12310 is further provided in the connecting end 123, the second avoidance hole 126 communicates with the third avoidance hole 12310, the second fixed end 115 extends into the second avoidance hole 126 through the first avoidance hole 13233 and the third avoidance hole 12310, and is cooperatively connected with the pressing plate 14 extending into the second avoidance hole 126, so that the first cover plate 11 and the second cover plate 12 are cooperated.

[0036] In the present utility model, a second avoidance hole 126 is provided on the surface of the second cover plate 12 that abuts against the horizontal plane. When the base 1 is placed on the horizontal plane, the second cover plate 12 abuts against the horizontal plane, the pressing plate 14 extends into the second avoidance hole 126 and is connected to the first cover plate 11. Under the action of gravity, the sliding assembly 112 of the first cover plate 11 abuts against the second cover plate 12, so that the first cover plate 11 will no longer move towards the horizontal plane, thereby ensuring that the pressing plate 14 will not extend out of the second avoidance hole 126 to contact the horizontal plane. This setting avoids the friction between the pressing plate 14 and the horizontal plane during the rotation of the first cover plate 11 driving the pressing plate 14 when the device is running; further, when the device is running, the pressing plate 14 will not contact the second cover plate 12 in the second avoidance hole 126, ensuring that no additional friction is generated when the first cover plate 11 rotates relative to the second cover plate 12. This setting not only improves the smoothness and stability of the device operation, but also reduces the wear between components and extends the service life of the device; further, the pressing plate 14 is connected to the first cover plate 11 by means of threaded connection or the like, further enhancing the stability of the overall structure.

[0037] Further, as Figures 1-3 shown in a clamping and swinging device of a blowing device, wherein a support end 124 extending from the second cover plate surface 125 towards the first cover plate 11 is provided in the second inner cavity 122, a sliding surface 1241 is provided on the side of the support end 124 away from the second cover plate surface 125, the sliding assembly 112 is provided with a support column extending from the first cover plate 11 towards the second cover plate 12 and a rolling bead located at one end of the support column, and the rolling bead rolls on the sliding surface 1241 to achieve the sliding fit between the first cover plate 11 and the second cover plate 12, and the limiting end 121 extends into the first inner cavity 111 and cooperates with the inner wall of the first inner cavity 111 to limit the rotation trajectory of the first cover plate 11.

[0038] The utility model realizes the smooth sliding between the first cover plate 11 and the second cover plate 12 through the rolling cooperation between the rolling beads on the sliding assembly 112 and the sliding surface 1241. This setting effectively reduces the friction during the rotation of the first cover plate 11, ensures the smoothness of its rotation, thereby reducing noise and wear. Further, the limiting end 121 extends into the first inner cavity 111 and cooperates with its inner wall, accurately restricting the rotation trajectory of the first cover plate 11, so that the first cover plate 11 can only rotate around the center of the second cover plate 12 by a certain angle, ensuring the stability of the device during operation. Further, the limiting end 121 and the inner wall of the first inner cavity 111 are in clearance fit, further ensuring the smoothness when the first cover plate 11 rotates relative to the second cover plate 12. Further, the diameter of the limiting end 121 gradually increases upward from the second cover plate surface 125, and the diameter of a part at the uppermost end remains unchanged. Only this part cooperates with the inner wall of the first inner cavity 111. This setting reduces the contact area between the first cover plate 11 and the second cover plate 12 during rotation, thereby reducing the friction during rotation and making the rotation process smoother.

[0039] Further, as Figures 1-3 shown in a clamping and swinging device of a blowing device, wherein the supporting end 124 and the second cover plate surface 125 enclose a counterweight area 127, at least one counterweight block 1271 is provided in the counterweight area 127, and at least one anti-slip pad 128 is further provided on the surface of the second cover plate 12 in contact with the horizontal plane.

[0040] The utility model increases the friction between the second cover plate 12 and the horizontal plane by providing the counterweight block 1271 in the counterweight area 127 and the anti-slip pad 128 on the surface of the second cover plate 12 in contact with the horizontal plane, so as to avoid the phenomenon of sliding or displacement of the second cover plate 12 when the first cover plate 11 rotates, and enhances the stability of the device.

[0041] Further, as Figures 1-3 shown in a clamping and swinging device of a blowing device, wherein the support rod 2 further has a first connection portion 21 at one end, a second connection portion 22 at the other end, and a first adjustment assembly 23 between the first connection portion 21 and the second connection portion 22. The second connection portion 22 is fixedly connected to the fixing hole 1151 so that the support rod 2 is fixedly connected to the first cover plate 11, and the first adjustment assembly 23 can adjust the length of the support rod 2.

[0042] In the present utility model, the second connecting portion 22 is fixedly connected to the first cover plate 11 through the fixing hole 1151. The connection between the support rod 2 and the fixing hole 1151 can be achieved by various methods such as fastener connection, interference fit, mortise and tenon connection, and groove key connection. This setting makes the process of disassembling the support rod 2 more convenient, and users can select the most suitable connection method according to different working conditions to ensure the stability and reliability of the device in different usage environments. Further, the length of the support rod 2 is adjusted by the first adjusting assembly 23, enabling the device to adapt to different working environments and usage requirements. This setting not only improves the versatility and adaptability of the device but also provides users with more usage options.

[0043] Further, as Figures 1-5 shown in a clamping and swinging device for a blowing device, wherein the fixed seat 3 is provided with a clamping portion 32, a second adjusting assembly 31 respectively connected to the clamping portion 32, and a third connecting portion 33. The third connecting portion 33 is provided with a rotating shaft 331 and a locking assembly 332. The first connecting portion 21 is provided with a rotating hole 221. The second adjusting assembly 31 adjusts the opening degree of the clamping portion 32. The rotating hole 221 is rotationally matched with the rotating shaft 331 so that the fixed seat 3 and the support rod 2 are rotationally matched. The locking assembly 332 is used to fix the position of the fixed seat 3.

[0044] In the present utility model, by providing the fixed seat 3 with a clamping portion 32 whose opening degree can be adjusted and a second adjusting assembly 31 for opening the clamping portion 32, the fixed seat 3 can be installed with blowing devices of different specifications, bringing great convenience to users. Further, through the rotating hole 221 and the rotating shaft 331, users can adjust the angle between the blowing device and the horizontal plane, and adjust the blowing direction angle according to practical needs, enhancing the practicality and flexibility of the device. Further, through the locking assembly 332, the blowing device can be locked at a specific required angle, thereby preventing angle deviation caused by vibration or other external factors and ensuring a continuous and stable wind direction output.

[0045] As Figures 1-6 shown, the implementation manner of this embodiment is as follows:

[0046] The device is composed of a base 1, a support rod 2 and a fixing seat 3. The base 1 adopts a double-cover design. The first cover plate 11 is slidably mated with the second cover plate 12 through a sliding component 112, and the first cover plate 11 rotates and swings around the center of the second cover plate 12 at a specific angle. A DC drive component 13 is installed inside the first cover plate 11. This component includes a low-torque driver 131 and a torque amplifier 133, which are used to provide sufficient torque for the first cover plate 11 to achieve the swinging function of the first cover plate 11. The support rod 2 is connected to the first cover plate 11 through a fastener, so that one end of the support rod 2 is connected to the base 1 and the other end is connected to the fixing seat 3. The fixing seat 3 is provided with a clamping part 32, and the opening degree of the clamping part 32 can be adjusted through a second adjustment component 31 to adapt to and install hair-drying devices of different specifications. In this embodiment, the hair-drying device is a hair dryer. In addition, a rotating shaft 331 and a locking component 332 are provided on the fixing seat 3, and a rotating hole 221 and a first adjustment component 23 are provided on the support rod 2. Through the cooperation of the rotating hole 221 and the rotating shaft 331, the user can conveniently adjust the angle of the hair-drying device, and use the locking component 332 to lock the angle of the fixing seat 3 at the required position. The first adjustment component 23 can be used to adjust the length of the support rod 2.

[0047] The specific operation is as follows:

[0048] During use, the user first needs to adjust the second adjustment component 31 according to the size of the hair-drying device to open the clamping part 32 to a width suitable for installing the hair-drying device, and then install the hair-drying device on the fixing seat 3. Then, the length of the support rod 2 is adjusted through the first adjustment component 23 to adjust the hair-drying device to a suitable height. When the hair-drying device is fixed, the user can easily rotate the fixing seat 3 through the cooperation of the rotating shaft 331 and the rotating hole 221, and then adjust the up-and-down angle of the hair-drying device. After the adjustment is completed, the locking component 332 is used to lock the angle of the hair-drying device on the fixing seat 3. Finally, the DC drive component 13 is started, and the low-torque driver 131 will generate sufficient torque through the torque amplifier 133 to drive the first cover plate 11 to swing relative to the second cover plate 12, and then drive the hair-drying device on the support rod 2 and the fixing seat 3 to swing, realizing the function of blowing hair without holding.
