Technical Field
[0001] This invention relates to the technical field of body dryers, and in particular to 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 dryers have the following shortcomings: Since dryers are usually used in environments with high humidity and temperature, the main control board inside the dryer usually cannot be effectively cooled, and its surface is usually covered with a certain amount of water vapor, which is not conducive to extending its service life; dryers are noisy when they are working, which is not good for human health and the environment; dryers have a single air blowing position, resulting in insufficient air volume and uneven air speed, which is not conducive to achieving a fast drying effect. Summary of the Invention
[0004] The present invention aims to overcome the shortcomings of the slow drying speed of existing dryers and provides a dryer that improves the drying speed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A body dryer includes a housing. A circuit board and two air ducts are detachably connected inside the housing. The air ducts are located on the side of the circuit board. Air inlets are located at both the front and rear ends of the housing, each air inlet communicating with one end of one of the two air ducts. The housing has two mounting ports that match the other ends of the two air ducts, located at opposite ends of the same side wall. The other end of each air duct is sealed to its corresponding mounting port and has several air outlets. A filter, a motor, a main control board, and a heater are detachably connected inside the air ducts. The filter, motor, main control board, and heater are sequentially distributed along the air duct from one end connected to the air inlet to the other end. The main control board is electrically connected to the motor, heater, and circuit board. A touch panel and a power cord, both electrically connected to the circuit board, are located outside the housing. The touch panel and power cord are sealed to the housing.
[0006] The housing contains a detachable circuit board and two air ducts, which are located on the side of the circuit board. Air inlets are located at both the front and rear ends of the housing, each connected to one end of one of the two air ducts. The housing has two mounting ports that match the other ends of the two air ducts, located at opposite ends of the same side wall. The other end of each air duct is sealed to its corresponding mounting port and has several air outlets. A filter, motor, main control board, and heater are detachably connected within each air duct. These components are distributed sequentially along the air duct from the end connected to the air inlet to the other end. The main control board is electrically connected to the motor, heater, and circuit board. A touch panel and power cord, both electrically connected to the circuit board, are located outside the housing and are sealed to the housing. Users can control the dryer's start / stop and temperature adjustment via the touch panel. The main control board controls the motor and heater. Natural air, driven by the motor, is filtered and enters the air duct through the air inlet. After flowing through the main control board and being heated by the heater, it is finally blown onto the body through the air outlet to dry it. Therefore, the main control board is located between the heater and the motor, which facilitates heat dissipation and water vapor removal from the main control board by the natural cool air, thus extending its service life. The housing contains two air ducts, each equipped with a filter, motor, main control board, and heater. Through the above process, the heated air from the two air ducts is blown onto the front and back sides of the body through the air outlets at the two assembly ports, increasing the air volume and thus improving the drying speed. The ends of the air ducts are sealed to the corresponding assembly ports, and the touch panel and power cord are also sealed to the housing, improving the dryer's waterproof sealing. At the same time, since the motor is located inside the air duct, it helps to reduce noise.
[0007] Preferably, both ends of the top of the housing protrude outward to form bosses. One end of each boss is fixedly connected to the housing and forms an integral part therewith. The assembly port is located at the other end of the boss, and the end face of the boss containing one assembly port is inclined towards the boss containing the other assembly port, forming an inclined structure. The inclined arrangement of the end faces of the two assembly ports allows hot air to be blown more concentratedly to the front and back sides of the human body, improving the drying effect.
[0008] Preferably, the bottom of the housing is fixed with several foot pads, which are evenly distributed along the edge of the housing. The dryer is placed on the ground by the foot pads, which helps to prevent slipping and also helps to balance the vibration of the dryer and reduce noise.
[0009] Preferably, two circuit boards are detachably connected inside the housing, located on the left and right sides of the air duct, respectively. Human body sensors, electrically connected to each of the two circuit boards, are located on both sides of the housing. The circuit boards are electrically connected to the main control board. The dryer is controlled by human body sensors, providing timely and sensitive response and convenient operation. When a user straddles both sides of the dryer, the human body sensors detect the presence of a person and transmit a signal to the main control board, which then controls the operation of the dryer.
[0010] Preferably, the housing includes a cavity and two air inlet chambers, located at the front and rear ends of the housing respectively. The cavity is situated between the two air inlet chambers. The air duct is detachably connected to the cavity. The air inlet is located on one side of the air inlet chamber. One end of the air duct passes through the corresponding side of the air inlet chamber and connects to it. The portion of the air duct passing through the air inlet chamber is sealed to the side wall of the air inlet chamber. The air inlet chambers facilitate improved intake and filtration of natural wind, and allow for increased airflow through the air duct. The air inlet's location at the front and rear ends of the housing helps prevent hair and other impurities from entering the air duct.
[0011] Preferably, one side of the air inlet chamber where the air inlet is located and the other side of the air inlet chamber connected to the air duct both arch outward to form an arc-shaped structure with the same arc center, and a grille is provided at the air inlet. The arc-shaped structure design on both sides of the air inlet chamber helps to reduce wind resistance, so that the air duct plays a good guiding role in the intake of natural wind, further improving the intake effect of natural wind, and also helps to reduce noise.
[0012] Preferably, the two air ducts are 180-degree rotationally symmetrical. Each air duct includes an inlet pipe, a first straight pipe section, a second straight pipe section, and an outlet pipe. One end of the inlet pipe has its edge folded outwards to form a flange. One end of the inlet pipe passes through the side wall of the inlet chamber and connects to it. This flanged connection seals the inlet pipe to the side wall of the inlet chamber. The other end of the inlet pipe is detachably connected to one end of the second straight pipe section via the first straight pipe section. The other end of the second straight pipe section is snap-fitted to one end of the outlet pipe. The other end of the outlet pipe is sealed to the assembly port. The outlet is located at the other end of the outlet pipe. The filter is detachably installed inside the inlet pipe. The motor and main control board are detachably connected inside the first straight pipe section, and the heater is detachably connected inside the second straight pipe section. The segmented, detachable connection of the air ducts facilitates installation and disassembly.
[0013] Preferably, the other end of the second straight pipe section is located inside one end of the air outlet pipe, the heater is located inside the other end of the straight pipe section, the air outlet pipe is provided with an arc-shaped bending structure, one end of the air outlet pipe is uniformly transitioned to its other end through the arc-shaped bending structure and then sealed and connected to the assembly port, the center of the other end of the air outlet pipe is recessed into the air outlet pipe to form an air guide groove, the bottom of the air guide groove is hemispherical, the opening end of the air guide groove forms an outwardly opening horn mouth, the side wall of the air guide groove is provided with an arc-shaped surface, the bottom side wall of the air guide groove is uniformly transitioned to the horn mouth through the arc-shaped surface, and several air outlets are evenly distributed circumferentially on the end face of the opening end of the air guide groove. The arc-shaped bend in the air outlet duct reduces wind resistance, thereby reducing noise and energy loss during air delivery. The design of the air guide channel further reduces wind resistance, thus reducing noise. The hemispherical bottom shape and flared opening of the air guide channel help prevent water from splashing into the duct, providing good waterproofing. Several air outlets are evenly distributed circumferentially on the opening end face of the air guide channel, ensuring that hot air is evenly directed towards the human body, improving comfort.
[0014] Preferably, an annular groove is provided on the outer wall of the other end of the air outlet duct, and a sealing ring is fitted inside the annular groove. The air outlet duct is sealed to the assembly port through the sealing ring. This helps to improve the waterproof effect at the joint between the assembly port and the air outlet duct.
[0015] Preferably, the straight pipe section includes an upper cover and a lower cover. Both sides of the opening end of the upper cover and the opening end of the lower cover are folded outward to form flange edges. The upper cover is detachably connected to the lower cover through the flange edges. A sealing groove is provided on the flange edge of the upper cover, and a sealing strip is provided in the sealing groove. A pressure strip matching the sealing groove is provided on the flange edge of the lower cover. The lower cover is sealed and connected to the upper cover by the pressure strip matching the sealing groove and pressing the sealing strip, thus forming a cavity. The motor is detachably installed in the cavity. A limiting slot matching the main control board is provided on one side of the opening end of the upper cover and one side of the opening end of the lower cover. One side of the main control board is located in the cavity after matching the limiting slot. The corresponding other side of the main control board passes through the mating part of the corresponding other side of the opening end of the upper cover and the corresponding other side of the opening end of the lower cover and is located outside the cavity and is electrically connected to circuit board one and circuit board two respectively. The corresponding other side of the main control board is sealed and connected to the upper cover and the lower cover respectively. The straight pipe section is assembled using an upper and lower cover, facilitating the installation and disassembly of the main control board and motor inside. The lower cover is sealed to the upper cover with a sealing strip, improving the waterproofness of the straight pipe section and reducing the chance of moisture damage to the motor and main control board, thus extending their service life. One side of the main control board matches the limiting slot, and the corresponding side of the main control board passes through the mating area between the corresponding side of the upper cover opening and the corresponding side of the lower cover opening, thus being located outside the cavity. This makes the positioning of the main control board simple and effective, and the installation and disassembly convenient and quick, while also facilitating circuit connection.
[0016] The beneficial effects of this invention are: it facilitates heat dissipation of the main control board, extending its service life; it increases airflow while simultaneously improving drying speed; it enhances the waterproof sealing of the body dryer; it allows hot air to be more concentrated on the front and back sides of the body, improving the drying effect; the body dryer is placed on the ground with feet, which helps prevent slipping and balances vibration; it reduces noise; the hot air is evenly distributed to the body, improving comfort; the body dryer is controlled by a human body sensor, providing timely and sensitive response and convenient operation; the air inlet is located at both ends of the casing, preventing hair and other impurities from entering the air duct; it is easy to install and disassemble; and it has good waterproof performance.

The other end of the air inlet pipe 20 is detachably connected to one end of the second straight pipe section 22 through the first straight pipe section 21. The other end of the second straight pipe section 22 is snapped to one end of the air outlet pipe 23. The other end of the air outlet pipe 23 is sealed to the assembly port 5. The air outlet 6 is located on the other end of the air outlet pipe 23. The filter 7 is detachably installed in the air inlet pipe 20. The motor 8 and the main control board 9 are detachably connected in the first straight pipe section 21. The heater 10 is detachably connected in the second straight pipe section 22.
[0026] like Figure 3 , Figure 4 and Figure 5As shown, the other end of the straight pipe section 22 is located inside one end of the air outlet pipe 23, and the heater 10 is located inside the other end of the straight pipe section. The air outlet pipe 23 has an arc-shaped bending structure. One end of the air outlet pipe 23 transitions evenly to its other end through the arc-shaped bending structure and is sealed to the assembly port 5. The center of the other end of the air outlet pipe 23 is recessed into the air outlet pipe 23 to form an air guide groove 25. The bottom of the air guide groove 25 is hemispherical, and the opening end of the air guide groove 25 forms an outwardly opening flared mouth 26.

[0028] The JQ808 body dryer allows users to control its start / stop and temperature adjustment via a touch panel 11. When a user straddles the sides of the dryer, a human body sensor 16 detects their presence and sends a signal to the main control board 9, which then controls the airflow. Specifically, the main control board 9 controls the motor 8 and heater 10. Natural air, driven by the motor 8, is filtered by the filter 7 and enters the air duct 3 through the air inlet 4. After flowing through the main control board 9, it is heated by the heater 10 and finally blown onto the body through the air outlet 6, effectively drying the body while simultaneously allowing the cool air to dissipate heat and remove water vapor from the main control board 9, thus extending its lifespan. The housing 1 contains two air ducts 3, each equipped with a filter 7, a motor 8, and a main control board 10. Through the above process, the heated air in the two air ducts 3 is blown from the air outlets 6 at the two assembly ports 5 to the front and back sides of the human body, which increases the air volume and improves the drying speed. The inclined setting of the end face of the boss 13 where the two assembly ports 5 are located means that the air outlets 6 face the direction of the human body, which makes it easier for the hot air to be blown to the front and back sides of the human body more concentrated, thus improving the drying effect. The hot air is blown evenly to the human body through several air outlets 6, which helps to improve the comfort of the human body.
