Description

Technical Field

[0001] This utility model relates to the field of electrical equipment, and in particular to a vibration reduction and noise reduction device for a hair dryer stator support. Background Technology

[0002] A vibration damping and noise reduction device for the stator bracket of a hair dryer is a technology or component used to reduce the vibration and noise generated by the hair dryer during operation. In a hair dryer, the stator is part of the motor, which works with the rotor to generate rotational force to drive the fan. Since vibration and noise are inevitably generated during motor operation, these vibrations not only affect the comfort of use but may also damage other internal components of the hair dryer, reducing its lifespan.

[0003] In existing hair dryer structures, the electric motor, as the core driving component, generates significant mechanical vibration during high-speed operation. Since the stator is usually connected and fixed to other structural components via a bracket, the vibration is easily transmitted to the entire body through the bracket. This vibration not only leads to unstable operation of the device and reduces comfort during use, but may also accelerate fatigue damage to the stator, bracket, and related connecting components, thereby affecting the overall performance and lifespan of the hair dryer. In addition, long-term vibration may also cause problems such as increased noise, loose structure, and even motor eccentricity, further restricting the reliability of the product and the user experience.

[0004] To address the above issues, a vibration reduction and noise reduction device for the stator support of a hair dryer needs to be designed. Utility Model Content

[0005] To overcome the significant mechanical vibration generated during high-speed operation, since the stator is usually connected and fixed to other structural components through a bracket, the vibration can easily be transmitted to the entire machine body through the bracket. This vibration not only leads to unstable operation of the equipment and reduces the comfort during use, but also provides a vibration reduction and noise reduction device for the stator bracket of a hair dryer.

[0006] The technical solution of this utility model is as follows: a vibration reduction and noise reduction device for a hair dryer stator bracket, comprising a stator, a bracket, a connecting rod, a guide block, a fixing plate, a spring, a damping block, and fixing bolts. The brackets are symmetrically placed on the left and right sides of the outer side of the stator. Two connecting rods are connected to the outer sides of each bracket. A guide block is connected to the outer end of each connecting rod. Each connecting rod slides with the guide block at a corresponding position. A fixing plate is connected between the outer sides of every two guide blocks. A damping block is provided inside each guide block. A spring is connected between each connecting rod and the corresponding fixing plate. Two fixing bolts are threadedly connected to the top and bottom of each of the two brackets.

[0007] Furthermore, it also includes a connecting cylinder, a guide rod, and a second spring. Two connecting cylinders are symmetrically connected on the upper and lower sides of the right side of the bracket. A guide rod is slidably connected inside each connecting cylinder, and a second spring is connected between each guide rod and the corresponding connecting cylinder.

[0008] Furthermore, it also includes heat dissipation fins, with multiple heat dissipation fins evenly spaced on the outer sides of the two brackets.

[0009] Furthermore, multiple shock-absorbing blocks are made of rubber.

[0010] Furthermore, the inner sides of the two supports are designed with an arc shape.

[0011] Furthermore, the multiple heat dissipation fins are evenly spaced.

[0012] The beneficial effects of this utility model are as follows: by setting multiple springs, corresponding compression or tensile deformation can be generated when the stator shifts left or right, effectively absorbing vibration energy; by setting multiple damping blocks, the buffering effect on high-frequency vibration is enhanced and noise is reduced; by designing two supports, the two supports are used to support and clamp the stator; by cooperating with the connecting rod and the guide block, the stable sliding displacement of the two supports is realized, thereby guiding the stator to move in a predetermined direction when it vibrates.

[0018] The present invention will now be described in detail with reference to the accompanying drawings.

[0019] Example: A vibration damping and noise reduction device for a hair dryer stator support, such as... Figures 1-4As shown, the device includes a stator 1, a bracket 2, a connecting rod 3, a guide block 4, a fixing plate 5, a spring 6, a damping block 7, a fixing bolt 8, a connecting cylinder 9, a guide rod 10, a spring 11, and heat dissipation fins 12. The brackets 2 are symmetrically placed on the outer sides of the stator 1. The inner surfaces of the two brackets 2 are arc-shaped. The brackets 2 are used to fix and support the stator 1. Two connecting rods 3 are connected to the outer surfaces of each bracket 2. Each connecting rod 3 has a guide block 4 connected to its outer end. Each connecting rod 3 slides with the corresponding guide block 4. The guide block 4 limits the sliding path of the connecting rod 3, serving as a guide and limiting element. A fixing plate 5 is connected between the outer sides of every two guide blocks 4. Each guide block 4 contains a damping block 7, which is made of rubber. The structure has good elasticity and vibration absorption performance, further improving the shock absorption effect of stator 1 and reducing noise. Each connecting rod 3 is connected to the corresponding fixed plate 5 with a spring 6. The upper and lower sides of the two brackets 2 are symmetrically connected with two fixing bolts 8, which are used to fasten the two brackets 2 together. The upper and lower sides of the right side of the bracket 2 are symmetrically connected with two connecting cylinders 9. Each connecting cylinder 9 is slidably connected with a guide rod 10. Each guide rod 10 is connected to the corresponding connecting cylinder 9 with a spring 11. Multiple heat dissipation fins 12 are evenly spaced on the outer side of the two brackets 2. The multiple heat dissipation fins 12 are evenly spaced, which can increase the heat dissipation area of ​​the overall structure and help the heat generated by stator 1 to dissipate quickly during operation.

[0020] When this device is needed, the operator places the two brackets 2 on both sides of the stator 1 and connects and fixes the two brackets 2 by inserting multiple fixing bolts 8. The specific operation is as follows: insert the fixing bolts 8 through the left bracket 2 and make it contact the right bracket 2, then rotate the fixing bolts 8 to gradually tighten them. During the rotation of the fixing bolts 8, their right end will contact the guide rod 10 and push the guide rod 10 to move outward along the connecting cylinder 9, compressing the spring 11. Stop rotating when the fixing bolts 8 are fully tightened. Repeat this operation until all fixing bolts 8 are installed. At this time, the two brackets 2 are firmly connected together, and the entire device can be installed inside the blower for subsequent use. During the operation of the blower, the stator 1 will vibrate due to its operation. When the stator 1 shifts to the left, it will drive... The left support 2 and the two left connecting rods 3 slide to the left along the two left guide blocks 4. At this time, the two left springs 6 are compressed. At the same time, the right support 2 drives the two right connecting rods 3 to move to the left along the two right guide blocks 4, and the two right springs 6 are stretched. During this process, the two right connecting rods 3 contact the two right damping blocks 7, thus playing a buffering role. Conversely, when the stator 1 is displaced to the right, the right support 2 drives the two right connecting rods 3 to move to the right along the two right guide blocks 4, and the two right springs 6 are compressed. Meanwhile, the left support 2 and the two left connecting rods 3 slide to the right along the two left guide blocks 4, and the two left springs 6 are stretched. This also effectively absorbs the vibration of the stator 1 and reduces noise and vibration.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
