Description

Technical Field

[0001] This utility model relates to the technical field of body dryers, and in particular to a noise reduction structure for a body dryer. Background Technology

[0002] After showering, people need to dry their bodies. Traditional methods of drying with towels have drawbacks in terms of dryness, hygiene, and convenience. For example, in public shower facilities, the shower stalls and changing rooms are often connected. The steam from the shower can drift into the changing room, making the air already quite humid. Using a towel, especially a semi-dry towel used in the shower, is ineffective in this situation. Not only does it feel uncomfortable to put on clothes, but it also increases the risk of catching a cold. Some customers use a hairdryer to dry themselves completely, which is time-consuming and also increases the risk of catching a cold, especially for people with long hair. Furthermore, given limited facilities, regulations in many public shower facilities often prohibit the use of hairdryers. In addition, from a hygiene perspective, using only one towel to dry oneself from head to toe is unhygienic. Moreover, using a towel to dry oneself in the changing room causes water to be squeezed onto the floor, increasing management costs and difficulties. Similarly, using hotel bath towels or hand towels to dry oneself also poses certain hygiene risks. In household use, the use of towels or bath towels presents challenges related to resource consumption, such as storage, washing, and drying. In medical and elderly care settings, issues like mobility limitations, frailty, and poor self-care abilities for patients or the elderly must be considered. Therefore, body dryers have been designed to address the shortcomings of traditional towel drying.

[0003] Existing hair dryers use a suction motor inside the duct, which heats the air before blowing it out through the outlet. The suction motor vibrates during operation, and this vibration can easily loosen the bolts connecting the duct to the casing, resulting in noise and hindering noise reduction. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of existing dryers that are prone to noise generation, and provides a noise reduction structure for a dryer that is conducive to noise reduction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A noise reduction structure for a body dryer, comprising:

[0007] The housing has air inlet grilles at both the front and rear ends, and air outlet areas at both the front and rear ends of the top of the housing. A touch panel and a power cord are respectively provided on the outside of the housing, and the touch panel and the power cord are sealed to the housing.

[0008] The circuit board is detachably installed inside the housing and is electrically connected to the touch panel and the power cord, respectively.

[0009] Two 180-degree rotationally symmetrical air ducts are located on the side of the circuit board. The air inlet grilles at the front and rear ends of the housing are respectively connected to one end of the two air ducts. The other ends of the two air ducts are respectively installed in the air outlet areas at the front and rear ends of the top of the housing. An air supply component and a heater are provided inside the air duct. The air supply component is located in the end of the air duct corresponding to the air inlet grille, and the heater is located in the other end of the air duct. Both the air supply component and the heater are electrically connected to the circuit board. Several evenly distributed mounting ears are fixed on the left and right sides of the air duct, and bolts are provided on the mounting ears.

[0010] Several mounting posts are provided. One end of each mounting post is provided with a threaded hole that matches the corresponding bolt. The other end of each mounting post is fixedly connected to the inner side wall of the housing. A rectangular opening is provided on the side wall of the other end of the mounting post, which communicates with the threaded hole. A magnetic suction element corresponding to the bolt is provided in the rectangular opening. The magnetic suction element slides up and down with the mounting post along the length of the rectangular opening and is fixedly locked to the mounting post. Both the touch panel and power cord are sealed to the casing, which helps improve the water resistance of the dryer. During operation, the operator connects the power cord and then controls the dryer through the touch panel. Under the action of the air supply component, the airflow enters the air duct from the air inlet grille, is heated by the heater, and then blows towards the body from the air outlet. The air duct is threaded to the mounting post by bolts and threaded holes. During operation, the air supply component will vibrate and transmit the vibration waves to the air duct, which can easily cause the bolts to loosen, resulting in noise. Therefore, after the bolts are properly engaged with the threaded holes, the operator needs to drive the magnetic suction device upward until it attracts the bolts. Once the magnetic suction device locks, it prevents the bolts from loosening and generating significant noise, thus achieving the purpose of noise reduction.

[0011] Preferably, the outer wall of the end of the mounting post that is fixedly connected to the housing is provided with an external thread section. The magnetic component includes a drive ring, a base, and a magnetic strip. The drive ring is sleeved on the mounting post. The inner circumferential surface of the drive ring is provided with an internal thread section and two annular limiting grooves. The internal thread section is located between the two annular limiting grooves. The drive ring is threadedly connected to the outer wall of the mounting post through the matching internal thread section and the external thread section. A limiting plate is provided in the annular limiting groove. The limiting plate is located in the rectangular opening and its two ends respectively cooperate with the two sides of the corresponding annular limiting groove. The base is located in the rectangular opening and is limited between the limiting plates on the two annular limiting grooves. One end of the magnetic strip is fixedly connected to the base, and the other end of the magnetic strip is located in the threaded hole and attracts the bolt. When the magnetic component moves, the operator rotates the drive ring, causing the drive ring to move linearly on the mounting post under the action of the interaction between the internal thread section and the external thread section on the mounting post. During this process, the magnetic strip gradually approaches the bolt until it attracts the bolt. Under the magnetic attraction, the engagement force between the bolt and the threaded hole, as well as the engagement force between the drive ring and the external thread section on the mounting post, is increased, thus locking the bolt in place and preventing it from loosening and generating excessive noise.

[0012] Preferably, one limiting plate is located near the threaded hole and fixedly connected to the upper side of the base. This limiting plate has a clearance hole that matches the magnetic strip, which is fixedly connected to the upper side of the base. The other limiting plate is located away from the threaded hole and fixedly connected to the lower side of the base. This design helps improve the stability of the structure and ensures that the magnetic strip always maintains its corresponding relationship with the bolt.

[0013] Preferably, the mounting ear has a groove that matches the end of the mounting post, and the end of the mounting post is inserted into the groove and connected to the mounting ear. During duct installation, the groove on the mounting ear first mates with the corresponding mounting post, which facilitates the initial positioning of the duct and improves the accuracy of the fit between the bolt and the corresponding threaded hole.

[0014] Preferably, the bottom of the housing is provided with several shock-absorbing pads, which are evenly distributed along the edge of the housing. These shock-absorbing pads serve two purposes: firstly, they reduce vibration during the operation of the dryer, thus further reducing noise; secondly, they improve the positional stability of the dryer.

[0015] Preferably, the shock-absorbing foot pad includes a support leg, one end of which is fixedly connected to the bottom of the housing, and the other end of which is provided with a pad block, which is elastically connected to the support leg. The pad block helps improve the positional stability of the dryer, and the elastic connection between the pad block and the support leg helps to reduce vibration during the operation of the dryer, thereby further reducing noise.

[0016] Preferably, the pad includes a rubber pad and a support block. One end of the support block has a mating groove that matches the support leg. The other end of the support leg is located in the mating groove and has a mounting groove. A shock-absorbing spring is installed in the mounting groove. One end of the shock-absorbing spring is fixedly connected to the bottom of the mounting groove, and the other end of the shock-absorbing spring passes through the opening of the mounting groove and is fixedly connected to the bottom of the mating groove. The other end of the support block is fixedly connected to the rubber pad. The rubber pad has anti-slip textures. The anti-slip textures on the rubber pad further improve the positional stability of the dryer during operation; the shock-absorbing spring helps to reduce vibration during operation and further reduce noise.

[0017] Preferably, the air outlet area protrudes outward to form a circular boss. One end of the boss is fixedly connected to the housing and forms an integral part therewith. The other end of the boss has a fitting port that matches the air duct. The end of the air duct is sealed to the corresponding fitting port, and its end face is on the same plane as the end face of the boss. The end of the air duct has several air outlets, which are evenly distributed along the circumference of the air duct. The protruding design of the boss helps to reduce the risk of water entering through the air outlets.

[0018] Preferably, the end face of the protrusion on one of the air outlet areas is inclined towards the other air outlet area to form an inclined surface. The inclined surface allows the air outlet areas at both ends of the dryer to better blow air onto the front and back parts of the body, which helps to improve the drying efficiency of the body, while further preventing water from flowing in and preventing hair from entering during operation.

[0019] Preferably, the air supply assembly includes a filter, a motor, and a main control board. The filter, motor, and main control board are all detachably connected to the air duct. The filter, motor, main control board, and heater are distributed sequentially from one end of the air duct corresponding to the air inlet grille to the other end. The heater and motor are both electrically connected to the circuit board via the main control board. The main control board controls the operation of the motor and heater. Driven by the motor, the airflow passes through the filter and enters the air duct through the air inlet grille. After flowing through the main control board, it is heated by the heater and finally blown onto the human body through the air outlet, effectively drying the body. Therefore, the main control board is located between the heater and the motor, facilitating heat dissipation and water vapor removal from the main control board by natural cool air, thus extending its service life.

[0020] The beneficial effects of this utility model are: it avoids the noise caused by loosening of the bolts connecting the air duct, thus achieving the purpose of noise reduction; the air inlet grille is set at both ends of the shell, making it difficult for hair to enter; it improves the accuracy of the fit between the bolts and the corresponding threaded holes; the shock-absorbing feet help to reduce vibration during the operation of the dryer, thus further reducing noise; on the other hand, it helps to improve the positional stability of the dryer; the raised design of the boss helps to reduce the risk of water flow entering the air outlet; the inclined surface allows the air outlet areas at both ends of the dryer to better blow towards the front and back parts of the body, which helps to improve the drying efficiency of the body, while further preventing water flow and preventing hair and liquids from entering during operation; the main control board is located between the heater and the motor, which facilitates the natural cool air to dissipate heat from the main control board and remove water vapor, thus achieving the purpose of heat dissipation of the main control board and extending the service life of the main control board.

Inside the air duct 7 at one end corresponding to the air inlet grille 2, the heater 9 is located inside the other end of the air duct 7. Both the air supply assembly 8 and the heater 9 are electrically connected to the circuit board 6. Several evenly distributed mounting ears 10 are fixed on both the left and right sides of the air duct 7. Bolts 11 are provided on the mounting ears 10. Several mounting posts 40 are provided. One end of the mounting post 40 is provided with a threaded hole 12 that matches the corresponding bolt 11. The other end of the mounting post 40 is fixedly connected to the inner side wall of the housing 1.

The magnetic suction member 14 slides up and down with the mounting post 40 along the length direction of the rectangular opening 13 and is fixedly locked with the mounting post 40.

[0033] like Figure 4As shown, the outer wall of the end of the mounting post 40 that is fixedly connected to the housing 1 is provided with an external thread section. The magnetic suction component 14 includes a drive ring 15, a base 16, and a magnetic strip 17. The drive ring 15 is sleeved on the mounting post 40. The inner circumferential surface of the drive ring 15 is provided with an internal thread section and two annular limiting grooves 18.

The drive ring 15 is threadedly connected to the outer wall of the mounting post 40 through the matching internal thread section and the external thread section. A limiting plate 19 is provided in the annular limiting groove 18. The limiting plate 19 is located in the rectangular opening 13 and its two ends are respectively engaged with the two sides of the corresponding annular limiting groove 18. The base 16 is located in the rectangular opening 13 and is limited between the limiting plates 19 on the two annular limiting grooves 18. One end of the magnetic strip 17 is fixedly connected to the base 16, and the other end of the magnetic strip 17 is located in the threaded hole 12 and attracts the bolt 11. One of the limiting plates 19 is located near the threaded hole 12 and is fixedly connected to the upper side of the base 16. The limiting plate 19 has a clearance hole 20 that matches the magnetic strip 17. The magnetic strip 17 is fixedly connected to the upper side of the base 16. The other limiting plate 19 is located away from the threaded hole 12 and is fixedly connected to the lower side of the base 16. The mounting ear 10 has a groove 21 that matches the end of the mounting post 40. The end of the mounting post 40 is inserted into the groove 21 and then connected to the mounting ear 10.

[0034] like Figure 2 As shown, the bottom of the housing 1 is provided with several shock-absorbing pads 22, which are evenly distributed along the edge of the housing 1.

[0035] like Figure 6 As shown, the shock-absorbing foot pad 22 includes a support leg 23. One end of the support leg 23 is fixedly connected to the bottom of the housing 1, and the other end of the support leg 23 is provided with a pad block 24, which is elastically connected to the support leg 23. The pad block 24 includes a rubber pad 25 and a support block 26. One end of the support block 26 is provided with a mating groove 27 that matches the support leg 23. The other end of the support leg 23 is located in the mating groove 27 and is provided with a mounting groove 28. A shock-absorbing spring 29 is provided in the mounting groove 28. One end of the shock-absorbing spring 29 is fixedly connected to the bottom of the mounting groove 28, and the other end of the shock-absorbing spring 29 passes through the opening end of the mounting groove 28 and is fixedly connected to the bottom of the mating groove 27. The other end of the support block 26 is fixedly connected to the rubber pad 25, and the rubber pad 25 is provided with anti-slip texture 30.

[0036] like Figure 1 and Figure 3As shown, the air outlet area 3 protrudes outward to form a circular boss 31. One end of the boss 31 is fixedly connected to the housing 1 and forms an integral part therewith. The other end of the boss 31 is provided with an assembly port 32 that matches the air duct 7. The end of the air duct 7 is sealed to the corresponding assembly port 32, and its end face is on the same plane as the end face of the boss 31. The end of the air duct 7 is provided with several air outlets 33, which are evenly distributed along the circumference of the air duct 7. The end face of the boss 31 on one of the air outlet areas 3 is inclined towards another air outlet area 3 to form an inclined surface 34.

[0037] like Figure 5 As shown, the air supply assembly 8 includes a filter 37, a motor 38, and a main control board 39. The filter 37, motor 38, and main control board 39 are all detachably connected to the air duct 7. The filter 37, motor 38, main control board 39, and heater 9 are distributed sequentially from one end of the air duct 7 corresponding to the air inlet grille 2 to the other end. The heater 9 and motor 38 are both electrically connected to the circuit board 6 through the main control board 39.

[0038] In the first embodiment, during operation, the operator connects the power supply via the power cord 5 and then controls the dryer via the touch panel 4. Under the action of the motor 38, the airflow enters the air duct 7 from the air inlet grille 2, is filtered by the filter 37, flows through the main control board 39, and is finally heated by the heater 9 before being blown towards the human body from the air outlet 33. In the above process, the main control board 39 is located between the heater 9 and the motor 38, which facilitates the natural cool air to dissipate heat from the main control board 39 and remove water vapor, thus extending the service life of the main control board 39. The duct 7 is threadedly connected to the mounting post 40 after the bolt 11 mates with the threaded hole 12. During operation, the motor 38 will vibrate and transmit the vibration waves to the duct 7, which can easily cause the bolt 11 to loosen, resulting in noise. Therefore, after the bolt 11 is properly mated with the threaded hole 12, the operator rotates the drive ring 15, causing the drive ring 15 to move linearly on the mounting post 40 under the interaction of its internal thread section and the external thread section on the mounting post 40. During this process, the magnetic strip 17 gradually approaches the bolt 11 until it attracts the bolt 11. Under the magnetic attraction, the mating force between the bolt 11 and the threaded hole 12, as well as the mating force between the drive ring 15 and the external thread section on the mounting post 40, is increased, thus locking the bolt 11 in place and preventing it from loosening and generating excessive noise.

[0039] In Example 2, the rubber pad 25 is elastically connected to the corresponding support block 26 via the shock-absorbing spring 29, which helps to absorb the vibration generated during the operation of the dryer and further reduce noise; the rubber pad 25 is provided with anti-slip texture 30, which further improves the positional stability of the dryer during operation.

[0040] In embodiment three, the protruding design of the boss 31 helps to reduce the entry of water flow into the air outlet 33. At the same time, the inclined surface 34 allows the air outlet areas 3 at both ends of the dryer to blow better towards the front and back parts of the human body, which helps to improve the drying efficiency of the human body, while further preventing water flow into the body and preventing hair from entering during operation.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
