Description

Technical Field

[0001] This invention relates to the field of quick-drying fan technology, and in particular to an adjustable, multifunctional quick-drying fan for intimate areas. Background Technology

[0002] A quick-drying fan for intimate areas is a bathroom appliance specifically designed for the rapid drying and care of the private parts of the body after bathing or cleaning. This device uses a gentle, controlled airflow to replace traditional towel wiping, providing non-contact drying of the genital area. This avoids skin damage caused by mechanical friction, reduces bacterial growth in damp environments, and improves personal hygiene. With the increasing demands for personal health care in modern society and the continued penetration of smart home technology into the bathroom sector, quick-drying fans for intimate areas are gradually becoming an important auxiliary appliance in the family health care system, and their functionality and user experience are receiving increasing attention.

[0003] However, existing quick-drying fans for intimate areas still have many shortcomings in practical use. First, regarding height adjustment, the height of existing devices is usually fixed, unable to be flexibly adjusted according to different user body shapes and heights. This forces users to frequently adjust their posture to adapt to the airflow position, resulting in a poor user experience and failing to meet the needs of multiple people sharing the device in a family setting. Second, in terms of ease of installation and disassembly, existing devices offer limited installation options, mostly supporting either fixed placement or wall mounting. This makes it difficult to accommodate diverse needs in different usage scenarios, and the disassembly and maintenance process is cumbersome, often requiring additional tools, making daily cleaning or replacement inconvenient for users. Furthermore, regarding temperature control and safety, existing products generally lack precise temperature control mechanisms, resulting in fluctuating airflow temperatures. This poses a risk of burning the delicate skin of the intimate area with high temperatures, or poor drying effects due to excessively low temperatures. In terms of hygiene, most devices lack integrated sterilization functions, failing to effectively inhibit the growth of bacteria and mold in the humid bathroom environment, posing a risk of secondary contamination. Regarding intelligent operation, existing products still require manual button operation, which is inconvenient when operating with wet hands and easily leads to cross-contamination. These shortcomings collectively restrict the improvement of existing quick-drying fans for intimate areas in terms of safety, hygiene, convenience, and adaptability, making it difficult to fully meet the higher overall quality requirements of modern users for intimate care devices.

[0034] The present disclosure will be further described below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solutions of the present disclosure more clearly, and should not be used to limit the scope of protection of the present disclosure.

[0035] Please see Figure 1-5 In this embodiment, each module (device, component, etc.) will be discussed in detail.

[0036] An adjustable multi-functional quick-drying fan for intimate areas includes a base 1, a square outer shell 2, a hollow rod 3, a lifting mechanism 4, and a hair dryer 6;

[0037] The square outer shell 2 is fixed to the base 1, and the hollow rod 3 is fixed to the end of the square outer shell 2 away from the base 1. The lifting mechanism 4 is installed on the base 1 and is used to drive the hair dryer 6 to adjust its height.

[0038] The lifting mechanism 4 includes a motor 41, a drive shaft 42, a drive bevel gear 43, a driving bevel gear 44, a threaded rod 45, a threaded block 46, a connecting rod 47, and a slide rod 48;

[0039] The motor 41 is fixed to the base 1, and the drive shaft 42 is fixed to the output end of the motor 41. The drive bevel gear 43 is fixed to the end of the drive shaft 42 away from the motor 41. The drive bevel gear 44 is meshed with the drive bevel gear 43. The threaded rod 45 is fixed to the drive bevel gear 44 and is rotatably connected to the square housing 2. One end of the threaded rod 45 is rotatably connected to the base 1. The threaded block 46 is threaded to the threaded rod 45, and the connecting rod 47 is fixed to the threaded block 46. The sliding rod 48 is fixed to the end of the connecting rod 47 away from the threaded block 46. The end of the sliding rod 48 away from the connecting rod 47 is fixed to the mounting plate 5. The blower 6 is mounted on the mounting plate 5 and is used to dry the private parts.

[0040] Further: The hair dryer 6 can be placed directly on the table, allowing for flexible placement and easy repositioning. The motor 41 is bolted to the inside of the base 1. The drive shaft 42 is fixed to the output end of the motor 41 via a coupling. The drive bevel gear 43 is keyed to the end of the drive shaft 42 furthest from the motor 41. The driving bevel gear 44 meshes with the driving bevel gear 43 at a 90-degree angle. The threaded rod 45 passes through and is fixed in the center hole of the driving bevel gear 44. The two ends of the threaded rod 45 are rotatably connected to the top plate of the base 1 and the square outer plate via bearings. On the bottom plate of shell 2, threaded block 46 is fitted onto threaded rod 45 and threadedly engaged with it. Connecting rod 47 is welded to one side of threaded block 46, and sliding rod 48 is welded to the end of connecting rod 47 away from threaded block 46. Mounting plate 5 is welded to the top of connecting rod 47. Hair dryer 6 is mounted on mounting plate 5 through self-locking mechanism 8. When motor 41 rotates forward and reverse, threaded block 46 moves up and down along threaded rod 45. The mounting plate 5 and hair dryer 6 are raised and lowered through connecting rod 47 and sliding rod 48, thus adapting to users of different heights.

[0041] Secondly, the hairdryer 6 uses a dedicated temperature control module inside, which keeps the constant air temperature between 28℃ and 33℃, close to the comfortable temperature range of human skin, avoiding the high temperature air from burning the delicate private skin. It is equipped with a brushless motor 41, which operates quietly and has a gentle airflow. It is adjusted to the optimal comfortable wind speed for the human body, dries quickly without the discomfort of strong wind, and gently dries water stains, protecting the private skin barrier.

[0042] Meanwhile, the hairdryer 6 integrates a UVC ultraviolet sterilization module inside the body, with a closed air duct sterilization design that prevents ultraviolet light from leaking out throughout the process, thus preventing ultraviolet rays from harming human skin and eyes. It can continuously sterilize the air duct and airflow of the body, inhibiting bacteria and mold that grow in the humid environment of the bathroom, reducing the risk of private parts infection from the source, and making it more hygienic to use. In addition, the hairdryer 6 is equipped with a high-precision human infrared sensor on the outside. It can automatically sense when you are near the device and turn on the airflow. It will automatically turn off after a delay when you leave. There is no need to touch the body of the device at all, avoiding secondary contamination. It is suitable for the humid and hygienic use scenario of the bathroom and is extremely easy to operate.

[0043] In addition, the Hair Dryer 6 has a built-in voice recognition module, which supports voice commands to turn the hair dryer on and off, and adjust the wind speed and temperature. When showering with wet hands, there is no need to touch the buttons. The entire process can be controlled by voice, which greatly improves the ease of use.

[0044] Secondly, the air inlet of the hair dryer 6 is equipped with a filter that can be removed for easy cleaning of hair, water stains and dirt, ensuring unobstructed airflow. At the same time, the bottom of the hair dryer 6 has an air outlet with an adjustable guide plate to accommodate different heights and sitting or standing postures for men and women, accurately targeting the private parts. In addition, the drive end of the hair dryer 6 is equipped with a silent brushless fan motor, which provides gentle airflow and avoids strong winds that irritate the mucous membranes of the private parts.

[0045] As a preferred embodiment, the mounting plate 5 has grooves 7 on both sides, and the blower 6 is equipped with a self-locking mechanism 8 for quick installation and removal of the blower 6.

[0046] The self-locking mechanism 8 includes a telescopic rod 81, a locking ball 82, a return spring 83, and a socket 84. The telescopic rod 81 is fixedly connected to the groove 7, and the locking ball 82 is fixedly connected to the end of the telescopic rod 81 away from the groove 7. The return spring 83 is sleeved on the telescopic rod 81, and the two ends of the return spring 83 are fixedly connected to the groove 7 and the locking ball 82 respectively. At the same time, the locking ball 82 is slidably connected through the socket 84, which is located on the hair dryer 6.

[0047] like Figure 4-5 As shown: When installing the hair dryer 6, align the hair dryer 6 with the mounting plate 5 and press it down. The retaining ball 82 compresses the return spring 83 under the action of the inclined plane and retracts inward. When the socket 84 is aligned with the retaining ball 82, the return spring 83 rebounds and pushes the retaining ball 82 into the socket 84 to complete the locking. When disassembling, pull the hair dryer 6 outward to make the retaining ball 82 disengage from the socket 84, and then the hair dryer 6 can be taken out upward, realizing tool-free quick disassembly and assembly.

[0048] In a preferred embodiment, the hollow rod 3 is provided with a groove 9, and the connecting rod 47 is slidably connected through the groove 9 to limit and guide the movement of the threaded block 46.

[0049] like Figure 3 As shown: When the threaded block 46 moves up and down, the connecting rod 47 slides synchronously in the slide groove 9. The two side walls of the slide groove 9 form a lateral limit on the connecting rod 47 to prevent the threaded block 46 from rotating circumferentially with the threaded rod 45, ensuring that the mounting plate 5 and the blower 6 only move smoothly up and down in the vertical direction and avoid shaking.

[0050] In a preferred embodiment, a telescopic column 10 is fixedly connected to the base 1 to limit and support the lifting of the mounting plate 5, and the end of the telescopic column 10 away from the base 1 is fixedly connected to the mounting plate 5.

[0051] like Figure 3 As shown: When the mounting plate 5 is raised or lowered, the telescopic column 10 extends and retracts synchronously, forming a support structure with the self-locking mechanism 8, which enhances the stability of the mounting plate 5. At the same time, the telescopic column 10 mechanically limits the extreme lifting and lowering position of the mounting plate 5 to prevent the threaded block 46 from dislodging from the threaded rod 45, thus playing a safety protection role.

[0052] As a preferred embodiment, the mounting plate 5 is provided with a square opening 11, through which a slider 12 is slidably connected. One end of the slider 12 is fixed to the hair dryer 6, and the end of the slider 12 away from the hair dryer 6 is fixed to a hook 13 for hanging the hair dryer 6 on the wall.

[0053] like Figure 4 As shown: When the hair dryer 6 needs to be removed from the wall for use, it can be hung on a wall nail or adhesive hook in the bathroom via the hook 13 on the back, achieving wall-mounted drying and expanding the usage scenarios.

[0054] In a preferred embodiment, the bottom of the base 1 is fixed with casters 14 for moving the device.

[0055] like Figure 2 As shown: There are four sets of casters 14, which are evenly distributed at the bottom of the base 1.

[0056] Working principle: First, the motor 41 is started. Its output end drives the drive bevel gear 43 to rotate through the drive shaft 42. The drive bevel gear 43 meshes with the active bevel gear 44, which in turn causes the threaded rod 45, which is fixed to the active bevel gear 44, to rotate inside the square housing 2. The threaded block 46, which is threaded to the threaded rod 45, cannot rotate with the threaded rod 45 due to the circumferential limiting effect of the connecting rod 47, which is slidably connected to the slide groove 9. Thus, it moves vertically up and down along the threaded rod 45. Through the connecting rod 47 and the slide rod 48, it drives the mounting plate 5 and the hair dryer 6 mounted on it to move up and down synchronously, thereby realizing the flexible adjustment of the height of the hair dryer 6 to adapt to different needs. To meet the user's needs, the hair dryer 6 is quickly installed into the grooves 7 on both sides of the mounting plate 5 via the self-locking mechanism 8. During installation, the telescopic rod 81 in the groove 7 drives the locking ball 82 to compress the return spring 83 and then locks into the insertion hole 84 on the hair dryer 6 to achieve fixation. When disassembling, the hair dryer 6 can be quickly removed by pulling it outward. In addition, a slider 12 is slidably connected in the square opening 11 on the mounting plate 5. One end of the slider 12 is fixed to the hair dryer 6, and the other end is fixed to a hook 13. The hair dryer 6 can be removed from the mounting plate 5 and wall-mounted for use. After the hair dryer 6 is turned on, it can quickly dry the user's private parts, achieving a multi-functional and adjustable quick-drying effect.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
