Description

Technical Field

[0001] The present invention relates to the technical field of dry body machines, and in particular to a low-noise dry body machine. Background Art

[0002] After taking a bath, people need to dry their bodies. The traditional way of drying the body with a towel has defects in terms of dryness, hygiene, convenience, etc. For example, in public shower places, the shower room and the changing room are often connected together, and the mist in the shower room will drift into the changing room, resulting in high humidity in the air of the changing room itself. At this time, relying solely on a towel, especially a semi-dry towel used for showering, to dry the body has a very poor effect. At this time, not only does it feel uncomfortable to put on clothes, but it is also easy to catch a cold when going out. Some customers will use a hair dryer to blow their whole body, which is time-consuming and also easy to catch a cold. Especially for people with long hair, it is very time-consuming and troublesome. Moreover, under the condition of limited equipment, the management regulations of those public shower places often do not allow using a hair dryer to blow the body. In addition, from the perspective of hygiene, if only one towel is brought, it is not hygienic to use it to dry the body from head to toe. And when drying the body with a towel in the changing room, the water from drying the body will be squeezed on the ground, resulting in an increase in management costs and difficulties. Another example is using the hotel's bath towel or towel to dry the body in the hotel, which also has certain hygiene risk problems. In terms of household use, there are also problems of resource consumption such as the placement, cleaning, and drying of these bath products when people use towels or bath towels. In the medical and elderly care aspects, problems such as the inconvenience of movement, weakness of constitution, and poor self-care ability of patients or the elderly also need to be considered. Therefore, people have designed dry body machines to blow dry people's bodies, which can solve the above-mentioned defects of drying the body with a towel.

[0003] In the existing dry body machine, a suction motor is arranged in the air duct, and then after being heated by a heater, it is blown out from the air outlet. During the operation of the suction motor, vibrations will be generated, and the vibrations are very likely to cause the bolts connecting the air duct and the housing to become loose, thus easily generating noise and being not conducive to noise reduction. Summary of the Invention

[0004] The present invention is to overcome the deficiency that the dry body machine in the prior art is prone to generate noise, and provides a low-noise dry body machine that is conducive to noise reduction.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A low-noise dry body machine, which includes: A housing, air inlet grilles are provided at both the front and rear ends of the housing, air outlet areas are provided at both the front and rear ends of the top of the housing, a touch panel and a power cord are respectively provided outside the housing, and the touch panel and the power cord are both hermetically connected to the housing; A circuit board, which is detachably installed in the housing and is electrically connected to the touch panel and the power cord respectively; Two air ducts that are rotationally symmetric by 180 degrees are both located on the sides of the circuit board. The air inlet grilles at the front and rear ends of the housing respectively correspond to and communicate with 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. A air supply component and a heater are provided in 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. A number of evenly distributed mounting ears are fixed on both the left and right sides of the air duct, and bolts are provided on the mounting ears; A number of mounting posts, one end of the mounting post is provided with a threaded hole matching the corresponding bolt, the other end of the mounting post is fixedly connected to the inner side wall of the housing, a rectangular opening communicating with the threaded hole is opened on the side wall of the other end of the mounting post, and a magnetic attraction member corresponding to the bolt is provided in the rectangular opening. The magnetic attraction member is slidably connected to the mounting post along the length direction of the rectangular opening and is fixedly locked with the mounting post. The touch panel and the power cord are both hermetically connected to the housing, which is beneficial to improving the waterproof and airtightness of the body dryer; during operation, after the operator connects the power supply through the power cord, the body dryer is controlled to work through the touch panel; under the action of the air supply component, the air flow enters the air duct from the air inlet grille, and then is blown to the human body from the air outlet area after being heated by the heater; the air duct is threadedly connected to the mounting post through the cooperation of the bolt and the threaded hole. Since during the working process, the air supply component will generate vibrations and transmit the vibration waves to the air duct, it is easy to cause the bolt to become loose, thus bringing noise. Therefore, after the bolt and the threaded hole are properly matched, the operator needs to drive the magnetic attraction member to move upward until the magnetic attraction member can attract the bolt. After the magnetic attraction member is locked, the bolt can be prevented from becoming loose and generating a large amount of noise, thus achieving the purpose of facilitating noise reduction.

[0006] Preferably, an external thread section is provided on the outer side wall of the end of the mounting post fixedly connected to the housing. The magnetic attraction member includes a driving ring, a base, and a magnetic attraction strip. The driving ring is sleeved on the mounting post. An internal thread section and two annular limiting grooves are provided on the inner circumferential surface of the driving ring. The internal thread section is located between the two annular limiting grooves. The driving ring is threadedly connected to the outer side wall of the mounting post through the matching of the internal thread section and the external thread section. A limiting plate is provided in the annular limiting groove. The limiting plate is located within the rectangular opening and its two ends are respectively matched with the two sides of the corresponding annular limiting groove. The base is located within the rectangular opening and is limited between the limiting plates on the two annular limiting grooves. One end of the magnetic attraction strip is fixedly connected to the base, and the other end of the magnetic attraction strip is located in the threaded hole and attracts the bolt. When the magnetic attraction member moves, the operator rotates the driving ring, so that the driving ring generates a linear motion on the mounting post under the action of the cooperation between the internal thread section and the external thread section on the mounting post. During this process, the magnetic attraction strip gradually approaches the bolt until it attracts the bolt. Under the magnetic attraction effect, the matching strength between the bolt and the threaded hole and the matching strength between the driving ring and the external thread section on the mounting post are increased, so that the bolt is locked on the original basis, avoiding the bolt from loosening and generating a large noise.

[0007] Preferably, one of the limiting plates is close to the threaded hole and fixedly connected to the upper side of the base. An avoidance hole matching the magnetic attraction strip is provided on this limiting plate. The magnetic attraction strip is fixedly connected to the upper side of the base, and the other limiting plate is away from the threaded hole and fixedly connected to the lower side of the base. Such a design is beneficial to improving the structural stability and facilitating the magnetic attraction strip to always maintain a corresponding relationship with the bolt.

[0008] Preferably, a groove matching the end of the mounting post is provided on the mounting ear. After the end of the mounting post is embedded in the groove, it is connected to the mounting ear. When installing the air duct, first, the groove on the mounting ear is matched with the corresponding mounting post, which is beneficial to the preliminary positioning of the air duct and improves the accuracy of the bolt matching with the corresponding threaded hole.

[0009] Preferably, a plurality of shock-absorbing foot pads are provided at the bottom of the housing, and the plurality of shock-absorbing foot pads are evenly distributed along the edge of the housing. On the one hand, the shock-absorbing foot pads are beneficial to shock absorption during the operation of the hair dryer, thereby facilitating further noise reduction; on the other hand, they are beneficial to improving the position stability of the hair dryer.

[0010] Preferably, the shock-absorbing foot pad includes a support leg. One end of the support leg is fixedly connected to the bottom of the housing, and a cushion block is provided at the other end of the support leg. The cushion block is elastically connected to the support leg. The cushion block is beneficial to improving the position stability of the hair dryer. At the same time, the cushion block is elastically connected to the support leg, which is beneficial to shock absorption during the operation of the hair dryer, thereby further reducing noise.

[0011] Preferably, the cushion block includes a rubber pad and a support block. One end of the support block is provided with a fitting groove matching with the support leg. The other end of the support leg is located in the fitting groove and is provided with a mounting groove. A damping spring is arranged in the mounting groove. One end of the damping spring is fixedly connected to the bottom of the mounting groove. The other end of the damping spring passes through the opening end of the mounting groove and is fixedly connected to the bottom of the fitting groove. The other end of the support block is fixedly connected to the rubber pad. The rubber pad is provided with anti-slip lines. The anti-slip lines on the rubber pad further improve the position stability during the operation of the body dryer. The damping spring is beneficial to shock absorption during the operation of the body dryer and is conducive to further reducing noise.

[0012] Preferably, the air outlet area bulges outwards to form a circular boss. One end of the boss is fixedly connected to the housing and forms an integral body. The other end of the boss is provided with a fitting port matching with the air duct. The end of the air duct is hermetically connected 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 is provided with a plurality of air outlets, and the plurality of air outlets are evenly distributed along the circumference of the air duct. The convex design of the boss is beneficial to reducing the risk of water flow entering the air outlets.

[0013] Preferably, the end face of the boss on one of the air outlet areas is inclined towards the other air outlet area to form an inclined surface. The inclined surface facilitates the air outlet areas at both ends of the body dryer to better blow towards the front and back parts of the human body, which is beneficial to improving the drying efficiency of the human body. At the same time, it further prevents water from flowing in and prevents hair from entering during the operation.

[0014] Preferably, the air supply assembly includes a filter, a motor and a main control board. The filter, the motor and the main control board are all detachably connected to the air duct. The filter, the motor, the main control board and the heater are distributed in sequence from one end corresponding to the air inlet grille to the other end of the air duct. The heater and the motor are both electrically connected to the circuit board through the main control board. The main control board controls the operation of the motor and the heater respectively. The air flow is filtered by the filter under the drive of the motor and enters the air duct from the air inlet grille, flows through the main control board and is heated by the heater, and finally blows towards the human body through the air outlet, playing the role of drying the human body. Therefore, the main control board is located between the heater and the motor, which is beneficial to the natural cold air to dissipate heat from the main control board and remove water vapor, achieving the purpose of facilitating the heat dissipation of the main control board and being conducive to extending the service life of the main control board.

[0015] The beneficial effects of the present invention are as follows: It avoids the bolts for the air duct connection from loosening and generating significant noise, thus achieving the purpose of facilitating noise reduction; the air inlet grille is arranged at the front and rear ends of the housing, 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 foot pads, on the one hand, facilitate shock absorption during the operation of the hair dryer, thus further facilitating noise reduction, and on the other hand, facilitate improving the position stability of the hair dryer; the convex design of the convex platform helps reduce the risk of water flow entering the air outlet; the inclined surface facilitates the air outlet areas at both ends of the hair dryer to better blow towards the front and back parts of the human body, which is conducive to improving the human body drying efficiency, while further preventing water from flowing in and preventing the entry of hair and liquid during the working process; the main control board is located between the heater and the motor, which is conducive to the natural cold air for heat dissipation of the main control board and the removal of water vapor, achieving the purpose of facilitating heat dissipation of the main control board and prolonging the service life of the main control board.

[0024] As Figure 2 shown, a plurality of shock-absorbing foot pads 22 are provided at the bottom of the housing 1. The plurality of shock-absorbing foot pads 22 are evenly distributed along the edge of the housing 1.

[0025] As Figure 6 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. A cushion block 24 is provided at the other end of the support leg 23. The cushion block 24 is elastically connected to the support leg 23. The cushion block 24 includes a rubber pad 25 and a support block 26. A matching groove 27 matching the support leg 23 is provided at one end of the support block 26. The other end of the support leg 23 is located in the matching 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. 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 matching groove 27. The other end of the support block 26 is fixedly connected to the rubber pad 25. Anti-slip lines 30 are provided on the rubber pad 25.

[0026] As Figure 1 、 Figure 3 and Figure 5As shown, the air outlet area 3 bulges outward to form a circular boss 31. One end of the boss 31 is fixedly connected to the housing 1 and integrated therewith. The other end of the boss 31 is provided with an assembly port 32 matching the air duct 7. The end of the air duct 7 is hermetically connected to the corresponding assembly port 32, and its end face is in the same plane as the end face of the boss 31. The end of the air duct 7 is provided with a plurality of air outlet openings 33, and the plurality of air outlet openings 33 are evenly distributed along the circumference of the air duct 7. The end face of the boss 31 on one air outlet area 3 is inclined towards the other air outlet area 3 to form an inclined surface 34.

[0027] As Figure 5 shown, the air supply assembly 8 includes a filter 37, a motor 38 and a main control board 39. The filter 37, the motor 38 and the main control board 39 are all detachably connected to the air duct 7. The filter 37, the motor 38, the main control board 39 and the heater 9 are sequentially distributed from one end corresponding to the air inlet grille 2 to the other end of the air duct 7. The heater 9 and the motor 38 are both electrically connected to the circuit board 6 through the main control board 39.

[0028] In the first embodiment, during operation, after the operator connects the power supply through the power cord 5, the operator then controls the operation of the drying machine through the touch panel 4; under the action of the motor 38, the air flow enters the air duct 7 from the air inlet grille 2, flows through the filter 37 for filtration and then through the main control board 39, and finally is blown towards the human body from the air outlet 33 after being heated by the heater 9; during the above process, the main control board 39 is located between the heater 9 and the motor 38, which is conducive to the natural cold air to dissipate heat from the main control board 39 and remove water vapor, facilitating the heat dissipation of the main control board 39, thereby facilitating the extension of the service life of the main control board 39. The air duct 7 is threadedly connected to the mounting post 40 through the cooperation of the bolt 11 and the threaded hole 12. Since during the working process, the motor 38 will generate vibrations and transmit the vibration waves to the air duct 7, it is easy to cause the bolt 11 to become loose, thereby generating noise. Therefore, after the bolt 11 is fitted with the threaded hole 12, the operator rotates the driving ring 15, so that the driving ring 15 makes a linear motion on the mounting post 40 under the action of the cooperation between the 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 cooperation force between the bolt 11 and the threaded hole 12 and the cooperation force between the driving ring 15 and the external thread section on the mounting post 40 are increased, so that the bolt 11 is locked on the original basis, avoiding the bolt 11 from becoming loose and generating greater noise.

[0029] In the second embodiment, the rubber pad 25 is elastically connected to the corresponding support block 26 through the shock absorption spring 29, which is conducive to absorbing the vibrations generated during the operation of the drying machine and further reducing noise; anti-slip patterns 30 are provided on the rubber pad 25, further improving the position stability of the drying machine during operation.

[0030] Embodiment 3. The convex design of the convex platform 31 helps to reduce the entry of water flow at the air outlet 33. At the same time, the inclined surface 34 facilitates the air outlet areas 3 at both ends of the drying machine to better blow towards the front and back parts of the human body, which helps to improve the drying efficiency of the human body, further prevent the entry of water flow, and prevent the entry of hair during operation.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
