Description

Technical Field

[0001] This utility model relates to the field of backpack hair dryer technology, specifically to a comfortable backpack hair dryer with a shock-absorbing structure. Background Technology

[0002] A backpack hair dryer is a portable hair dryer carried on the back, mainly used for cleaning and blowing operations in agriculture, landscaping, and sanitation. Its core design involves securing the main body of the device to the operator's back with a strap, freeing their hands to flexibly control the air nozzle, thus combining portability and work efficiency.

[0003] For example, Chinese patent CN220079866U discloses a backpack-style hair dryer, relating to the field of garden tool technology. It consists of a base, a damping rod, rubber shock absorbers, a spring, a slide rail, a sleeve shock absorber, a back frame, a motor, a pressurized air duct, a heat-dissipating frame, a flexible shaft air duct, a telescopic buckle, an operating handle, and a shoulder strap. When the motor's vibration is transmitted to the rod on the inner surface of the base, the first spring is compressed, causing the damping rod to extend and retract. The pressure is reduced by the damping rod and the rubber shock absorber at the bottom. The motor's vibration and the vertical vibration during walking are transmitted through the slide rail to the upper and lower fixedly connected sleeve shock absorbers. The vibration is reduced by the sliding of the slide rail and the sleeve shock absorbers. This device has a simple structure, is easy to operate, and improves user comfort.

[0004] However, the aforementioned backpack hair dryers have a single shock absorption dimension, which affects the actual experience when carrying them. Furthermore, the rigid back frame is in direct contact with the human body, causing pressure to concentrate on the shoulders, obstructing blood circulation, causing numbness in the shoulders, and affecting carrying comfort. Utility Model Content

[0005] The present invention aims to solve the problems mentioned in the background art by providing a comfortable backpack hair dryer with a shock-absorbing structure.

[0006] The specific technical solution is as follows:

[0007] A comfortable backpack hair dryer with a shock-absorbing structure includes: a hair dryer body, a back plate support on one side of the hair dryer body, a shock-absorbing component fixedly installed on one side of the back plate support, the shock-absorbing component including a U-shaped spring, the U-shaped spring being fixedly installed on one side of the back plate support, two slots on one side surface of the U-shaped spring, and a silicone block being glued to each of the two slots, and a soft cotton patch being glued to one side of each silicone block.

[0008] As a preferred embodiment of this utility model, a corrugated board is bonded between the two soft pads. The corrugated board is made of elastic polyurethane foam, and a shoulder strap is provided at one end of the upper surface of the back panel support.

[0009] As a preferred embodiment of this utility model, a reinforced V-shaped spring is installed at one end of the upper surface of the inner wall of the U-shaped spring, and the two ends of the reinforced V-shaped spring are connected to both sides of the inner wall of the U-shaped spring.

[0010] As a preferred embodiment of this utility model, two fixing rods are fixedly installed on one side of the inner wall of the U-shaped spring, and springs are provided around the two fixing rods, with a damper connected to the other end of the springs.

[0011] As a preferred embodiment of this utility model, a sleeve is connected to one side of the damper, and the sleeve is fixedly installed on the other side of the inner wall of the U-shaped spring. The sleeve has a circular groove with a diameter larger than that of the fixed rod.

[0012] As a preferred embodiment of this utility model, a linkage plate is fixedly installed on one end of the upper surface of the sleeve, a rotating shaft is rotatably installed on one end of the upper surface of the linkage plate, a connecting plate is rotatably connected to one end of the upper surface of the rotating shaft, a rotating shaft is rotatably connected to one side of the connecting plate, and the other end of the rotating shaft is rotatably installed on one side of the inner wall of the U-shaped spring.

[0013] This utility model has the following beneficial effects:

[0014] 1. The comfortable backpack hair dryer with shock absorption structure provided by this utility model, through the design of back plate support, U-shaped spring sheet and silicone block, when the user carries the hair dryer body through the shoulder strap, the body pressure is transmitted to the silicone block through the soft pad. The high elastic deformation of silicone absorbs high-frequency fine vibration. The wave plate is located between the two soft pads. The wave structure of the wave plate deforms when under pressure, disperses the pressure and increases the buffer stroke, improves the user's comfort when carrying it, reduces the fatigue of long-term use, and is suitable for long-term work. The U-shaped spring sheet, as the core load-bearing component, undergoes elastic deformation when walking or moving, offsetting low and medium frequency vibration. The reinforcement of the V-shaped spring sheet can improve the bending strength of the U-shaped spring sheet, prevent overload deformation, and extend its service life.

[0015] 2. The comfortable backpack hair dryer with shock absorption structure provided by this utility model, through the design of a fixed rod, spring, damper, and linkage plate, has a U-shaped spring sheet fixedly installed on one side of the back panel support. Therefore, only one side can deform. When the U-shaped spring sheet deforms due to the movement of the person carrying it and bends towards the back panel support, the sleeve side of the spring sheet undergoes relative displacement towards the fixed rod side. The two side walls are compressed near the spring, storing elastic potential energy. Then, the damper suppresses the rebound vibration, causing the sleeve to move closer to one end of the fixed rod. This causes the fixed rod to move axially within the sleeve's circular groove, eliminating lateral friction interference and improving shock absorption efficiency. When the sleeve moves closer to the fixed rod, the linkage plate fixedly connected to the upper surface of the sleeve moves along with it, pushing the rotating shaft. The connecting plate rotates around the rotating shaft and cooperates with the linkage plate to force the rotating shaft to rotate. The friction of the rotating shaft consumes low-frequency residual vibration, thereby improving shock absorption efficiency. Attached Figure Description

[0029] Example 1

[0030] The comfortable backpack hair dryer with a shock-absorbing structure provided in this embodiment, such as Figures 1-5 As shown, the device includes: a hair dryer body 1; a backplate bracket 2 on one side of the hair dryer body 1; a shock-absorbing component 3 fixedly installed on one side of the backplate bracket 2; the shock-absorbing component 3 includes a U-shaped spring 301, which is fixedly installed on one side of the backplate bracket 2; two slots are provided on one side surface of the U-shaped spring 301, and silicone blocks 303 are respectively adhered to each of the two slots; soft pads 302 are respectively adhered to one side of each silicone block 303; a corrugated board 304 is adhered between the two soft pads 302; the corrugated board 304 is made of elastic polyurethane foam; a shoulder strap 201 is provided at one end of the upper surface of the backplate bracket 2; a reinforcing V-shaped spring 306 is installed at one end of the upper surface of the inner wall of the U-shaped spring 301, and the two ends of the reinforcing V-shaped spring 306 are connected to the two sides of the inner wall of the U-shaped spring 301.

[0031] Through the design of the backplate bracket 2, U-shaped spring sheet 301, and silicone block 303, when the user carries the hair dryer body 1 on their back via the shoulder strap 201, the body pressure is transmitted to the silicone block 303 through the soft pad 302. The high elasticity of the silicone absorbs high-frequency micro-vibrations. The wave plate 304 is located between the two soft pads 302. The wave structure of the wave plate 304 deforms under pressure, dispersing pressure and increasing the cushioning stroke, improving the user's comfort when carrying the hair dryer, reducing fatigue during long-term use, and making it suitable for long-term work. The U-shaped spring sheet 301, as the core load-bearing component, undergoes elastic deformation during walking or movement to offset low- and medium-frequency vibrations. The reinforcement of the V-shaped spring sheet 306 can improve the bending strength of the U-shaped spring sheet 301, prevent overload deformation, and extend its service life.

[0032] Example 2

[0033] The comfortable backpack hair dryer with a shock-absorbing structure provided in this embodiment, such as Figures 1-5 As shown, the device includes: two fixing rods 312 fixedly installed on one side of the inner wall of a U-shaped spring 301, and springs 311 are provided around the two fixing rods 312. The other end of the springs 311 is connected to a damper 310. A sleeve 309 is connected to one side of the damper 310 and is fixedly installed on the other side of the inner wall of the U-shaped spring 301. The sleeve 309 has a circular groove with a diameter larger than that of the fixing rods 312. A linkage plate 308 is fixedly installed on one end of the upper surface of the sleeve 309. A rotating shaft 307 is rotatably installed on one end of the upper surface of the linkage plate 308. A connecting plate 305 is rotatably connected to one end of the upper surface of the rotating shaft 307. A rotating shaft 313 is rotatably connected to one side of the connecting plate 305. The other end of the rotating shaft 313 is rotatably installed on one side of the inner wall of the U-shaped spring 301.

[0034] Through the design of the fixed rod 312, spring 311, damper 310, and linkage plate 308, one side of the U-shaped spring piece 301 is fixedly installed on one side of the back plate bracket 2, so only one side can deform. When the U-shaped spring piece 301 deforms due to the carrier's movement and bends towards the back plate bracket 2, its sleeve 309 undergoes relative displacement towards the fixed rod 312. The two side walls near the spring 311 are compressed, storing elastic potential energy. This elastic potential energy is then suppressed by the damper 310, causing the sleeve... The sleeve 309 moves closer to one end of the fixed rod 312, causing the fixed rod 312 to move axially within the circular groove of the sleeve 309, eliminating lateral friction interference and improving damping efficiency. Then, as the sleeve 309 moves closer to the fixed rod 312, the linkage plate 308 fixedly connected to the upper surface of the sleeve 309 moves accordingly, pushing the rotating shaft 307. The connecting plate 305 rotates around the rotating shaft 313 and cooperates with the linkage plate 308 to force the rotating shaft 307 to rotate. The friction of the rotating shaft 307 consumes low-frequency residual vibration, thereby improving damping efficiency.

[0035] In summary, the comfortable backpack hair dryer with shock absorption structure provided in this embodiment has the following advantages: it can perform multi-dimensional shock absorption, improve the user's comfort when carrying it, and avoid the problem of shoulder numbness affecting the user experience during short-term carrying work.

[0036] When in use, when the user carries the hair dryer body 1 on their back using the shoulder strap 201, body pressure is transmitted to the silicone block 303 through the soft pad 302. The high elasticity of the silicone absorbs high-frequency micro-vibrations. The wave plate 304 is located between the two soft pads 302. The wave structure of the wave plate 304 deforms under pressure, dispersing pressure and increasing the cushioning stroke, improving user comfort and reducing fatigue during long-term use. One side of the U-shaped spring 301 is fixedly installed on one side of the back support 2, so only one side can deform. When the U-shaped spring 301 deforms due to the user's movement, it bends towards the back support 2, and its sleeve 309 laterally fixes the rod 31. When relative displacement occurs on both sides, the two side walls near the spring 311 are compressed, storing elastic potential energy. Then, the damper 310 suppresses the rebound vibration, causing the sleeve 309 to move closer to one end of the fixed rod 312. This causes the fixed rod 312 to move axially within the circular groove of the sleeve 309, eliminating lateral friction interference and improving shock absorption efficiency. As the sleeve 309 moves closer to the fixed rod 312, the linkage plate 308 fixedly connected to the upper surface of the sleeve 309 moves accordingly, pushing the rotating shaft 307. The connecting plate 305 rotates around the rotating shaft 313 and cooperates with the linkage plate 308 to force the rotating shaft 307 to rotate. The friction of the rotating shaft 307 consumes low-frequency residual vibration, thereby improving shock absorption efficiency and enhancing user comfort when carrying the load.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
