Description

TECHNICAL FIELD

[0001] The utility model relates to a dry body machine related technical field, especially a waterproof and dustproof structure of dry body machine. BACKGROUND

[0002] People need to dry the body after bathing. 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 dressing room are often connected together, and the mist in the shower room will drift into the dressing room, resulting in a high humidity in the dressing room. At this time, the effect of using a towel, especially a semi-dry towel used for showering, to dry the body is very poor. At this time, not only the body feels uncomfortable, but also it is easy to catch a cold when going out. Some customers will use a hair dryer to blow all over the body, which is time-consuming and also easy to catch a cold, especially for people with long hair. Moreover, in the case of limited equipment, the management regulations of those public shower places often do not allow the use of a hair dryer to dry 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. Moreover, if a towel is used to dry the body in the dressing room, the water used for drying will be squeezed onto the ground, resulting in an increase in management cost and difficulty. For example, in hotels, using hotel towels or towels to dry the body also has certain hygiene risks. As for household use, the use of towels or bath towels also has the problem of consumption of resources such as placement, cleaning and drying of these bathing products. As for medical and elderly care, the problems of inconvenience, weak constitution and poor self-care ability of patients or the elderly also need to be considered. Therefore, people have designed a dry body machine to dry the body, which can solve the above-mentioned defects of the traditional way of drying the body with a towel.

[0003] The existing dry body machine has the problem that hair and liquid are easy to enter the air outlet, especially in a humid environment, which affects the normal operation of the dry body machine and is not conducive to prolonging the service life of the dry body machine. UTILITY MODEL CONTENTS

[0004] The utility model discloses to overcome the insufficient that the dry body machine air outlet place easy to enter hair and liquid in the prior art, provide a kind of waterproof and dustproof structure of dry body machine of air outlet place not easy to enter hair and liquid.

[0005] In order to realize the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A waterproof and dustproof structure of a dry body machine, comprising:

[0007] A shell, the front and rear ends of the shell are provided with air inlet grilles, the front and rear ends of the top of the shell are provided with air outlet areas, the air outlet areas are outwardly protruding to form circular bosses, a touch panel and a power cord are respectively arranged outside the shell, and the touch panel and the power cord are both in sealed connection with the shell.

[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 air ducts are 180 degrees rotate symmetrically and are detachably connected to the housing. They 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. One end of the boss is fixedly connected to the housing and forms an integral part. The other end of the boss is provided with an assembly port that matches the other end of the corresponding air duct. The end of the air duct is sealed to the corresponding assembly port and its end face is on the same plane as the end face of the boss.

[0010] Several air outlets are evenly distributed at the ends of the air duct along its circumference;

[0011] The cover is rotatably and sealingly connected to the protrusion, and the cover has several through holes corresponding to the air outlets. The touch panel and power cord are both sealed to the housing, improving the dryer's waterproof and dustproof sealing performance. The protruding design of the protrusion reduces the risk of water entering through the air outlets. During use, the operator rotates the cover, connecting the through holes to the air outlets, allowing airflow to reach the body and dry it. When not in use, the operator rotates the cover again to block the air outlets, further improving the dryer's waterproof and dustproof effect, preventing hair and liquids from entering through the air outlets.

[0012] 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 flow and hair from entering during operation.

[0013] Preferably, a sealing gasket corresponding to the air outlet is provided between every two adjacent through holes. The sealing gasket is fixedly connected to the bottom of the cover, and the area of ​​the sealing gasket is larger than the area of ​​the air outlet and is interference-fitted with the air outlet. The design of the sealing gasket further improves the sealing effect of the air outlet, thereby improving the waterproof and dustproof effect.

[0014] Preferably, a rotating ring is fixedly protruding from the inner side of the opening end of the cover, and a rotating groove matching the rotating ring is provided on the edge sidewall of the boss. The cover is rotatably connected to the boss through the matching of the rotating ring and the rotating groove. This improves the connection strength between the cover and the boss, while ensuring an interference fit between the sealing gasket and the air outlet.

[0015] Preferably, the duct is equipped with an air supply component and a heater. The air supply component is located at one end of the duct corresponding to the air inlet grille, and the heater is located at the other end of the duct. Both the air supply component and the heater are electrically connected to the circuit board. Several evenly distributed mounting ears are fixed on both sides of the duct, and bolts are provided on the mounting ears. Several mounting columns are provided inside the housing. One end of each mounting column is provided with a threaded hole that matches the corresponding bolt. The other end of each mounting column 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 column. A magnetic suction component corresponding to the bolt is provided in the rectangular opening. The magnetic suction component slides up and down with the mounting column along the length of the rectangular opening and is fixedly locked to the mounting column. During operation, the operator connects the power cord to the power source and then controls the dryer via the touch panel. Under the action of the air supply component, the airflow enters the duct from the air inlet grille, is heated by the heater, and then blows onto the body from the air outlet. The duct is threaded onto the mounting post by bolts and threaded holes. During operation, the air supply component vibrates and transmits the vibration waves to the 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 upwards until it attracts the bolts. Once the magnetic suction device locks in place, it can prevent the bolts from loosening and generating significant noise.

[0016] 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.

[0017] 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.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] The beneficial effects of this utility model are as follows: The raised design of the boss reduces the risk of water entering through the air outlet. During use, the operator rotates the cover to connect the various through holes with the air outlet, facilitating airflow towards the body for drying. When not in use, the operator rotates the cover again to block the air outlet, further improving the dryer's waterproof and dustproof performance, preventing hair and liquid from entering the air outlet. The inclined surface allows the air outlets at both ends of the dryer to better direct airflow towards the front and back of the body, improving drying efficiency and further preventing water from entering and causing damage during operation. The design of the sealing gasket further improves the sealing effect of the air outlet, thereby improving the waterproof and dustproof effect; the air inlet grille is set at both ends of the housing, making it difficult for hair to enter; it avoids the bolts connecting the air duct from loosening and generating more noise, which helps to reduce noise; it improves the accuracy of the bolt and corresponding thread hole fit; the shock-absorbing feet help to reduce vibration during the operation of the dryer, thereby further reducing noise; on the other hand, it helps to improve the positional stability of the dryer; 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, thereby achieving the purpose of heat dissipation of the main control board and extending the service life of the main control board.

[0037] The end face of the protrusion 31 on one of the air outlet areas 3 is inclined toward the other air outlet area 3 to form an inclined surface 36.

[0038] like Figure 1 and Figure 7 As shown, a sealing gasket 37 corresponding to the air outlet 33 is provided between every two adjacent through holes 35. The sealing gasket 37 is fixedly connected to the bottom of the cover 34. The area of ​​the sealing gasket 37 is larger than the area of ​​the air outlet 33 and is interference-fitted with the air outlet 33. A rotating ring 38 is fixedly protruding from the inner side of the opening end of the cover 34. A rotating groove 39 matching the rotating ring 38 is provided on the edge side wall of the boss 31. The cover 34 is rotatably connected to the boss 31 through the matching of the rotating ring 38 and the rotating groove 39.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the air duct 7 is equipped with an air supply component 8 and a heater 9. The air supply component 8 is located in the end of the air duct 7 corresponding to the air inlet grille 2, and the heater 9 is located in the other end of the air duct 7. Both the air supply component 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 43 are provided. One end of the mounting post 43 is provided with a threaded hole 12 that matches the corresponding bolt 11. The other end of the mounting post 43 is fixedly connected to the inner side wall of the housing 1. A rectangular opening 13 is opened on the side wall of the other end of the mounting post 43, which communicates with the threaded hole 12. A magnetic suction component 14 corresponding to the bolt 11 is provided in the rectangular opening 13. The magnetic suction component 14 slides up and down with the mounting post 43 along the length direction of the rectangular opening 13 and is fixedly locked with the mounting post 43.

[0040] like Figure 4 As shown, the outer wall of the end of the mounting post 43 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 43. The inner circumferential surface of the drive ring 15 is provided with an internal thread section and two annular limiting grooves 18. The internal thread section is located between the two annular limiting grooves 18. The drive ring 15 is threadedly connected to the outer wall of the mounting post 43 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 43. The end of the mounting post 43 is inserted into the groove 21 and then connected to the mounting ear 10.

[0041] 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.

[0042] like Figure 6As 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.

[0043] like Figure 5 As shown, the air supply assembly 8 includes a filter 40, a motor 41, and a main control board 42. The filter 40, motor 41, and main control board 42 are all detachably connected to the air duct 7. The filter 40, motor 41, main control board 42, 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 41 are both electrically connected to the circuit board 6 through the main control board 42.

[0044] In Embodiment 1, the raised 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 36 allows the air outlet areas 3 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 and further prevents water flow and hair from entering during operation. When in use, the operator rotates the cover 34 so that several through holes 35 are connected to the air outlet 33 one by one, which facilitates the airflow to blow onto the body and dry the body. When not in use, the operator rotates the cover 34 again so that the cover 34 can block the air outlet 33, which further improves the waterproof and dustproof effect of the dryer.

[0045] In the second 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 41, the airflow enters the air duct 7 from the air inlet grille 2, is filtered by the filter 40, flows through the main control board 42, 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 42 is located between the heater 9 and the motor 41, which facilitates the natural cool air to dissipate heat from the main control board 42 and remove water vapor, thus extending the service life of the main control board 42. The duct 7 is threadedly connected to the mounting post 43 after the bolt 11 is engaged with the threaded hole 12. During operation, the motor 41 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 engaged with the threaded hole 12, the operator rotates the drive ring 15, which causes the drive ring 15 to move linearly on the mounting post 43 under the action of the interaction between the internal thread section and the external thread section on the mounting post 43. During this process, the magnetic strip 17 gradually approaches the bolt 11 until it attracts the bolt 11. Under the magnetic attraction, the engagement force between the bolt 11 and the threaded hole 12 and the engagement force between the drive ring 15 and the external thread section on the mounting post 43 are increased, so that the bolt 11 is locked on the original basis, preventing the bolt 11 from loosening and generating more noise.

[0046] In Example 3, the rubber pad 25 is elastically connected to the corresponding support block 26 through the shock-absorbing spring 29, which helps to absorb the vibration generated when the dryer is working and further reduce noise; the rubber pad 25 is provided with anti-slip texture 30, which further improves the positional stability of the dryer when it is working.

[0047] 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.
