[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] Reference Figures 1 to 3 According to an embodiment of the present invention, a foot dryer includes a base 100, a water absorbent member 300 and an air extraction device 200. The upper surface of the base 100 is provided with an air extraction position; the water absorbent member 300 is provided at the air extraction position, wherein the upper surface of the water absorbent member 300 is used to support the foot, and the water absorbent member 300 is used to absorb moisture from the sole of the foot; the air extraction device 200 is provided on the base 100, and an air extraction channel is connected between the air extraction position and the air extraction device 200, and the air extraction device 200 can extract moisture from the water absorbent member 300.

[0029] With the foot dryer provided by the present invention, people can stand on the water absorbent member 300 and directly absorb water from the soles of their feet through the water absorbent member 300 to dry their feet. The water in the water absorbent member 300 can be extracted by the air suction device 200 to reduce the water content of the water absorbent member 300, so that the water absorbent member 300 maintains its water absorbency and enables the water absorbent member 300 to be reused for a long time. Therefore, by adopting the above-mentioned arrangement, the foot dryer provided by the present invention can eliminate the heating device that consumes a lot of energy and is prone to safety problems, making the foot dryer simple in structure and low in cost, and can reduce energy consumption, making it more energy-saving, environmentally friendly, and safer.

[0030] Existing foot dryers require a heater to evaporate moisture from the feet, resulting in high power consumption (typically around 1 kilowatt). This requires power from the 110V or 220V grid. This can lead to leakage when used in humid environments like bathrooms, where the supply voltage exceeds 36V. This leakage can easily cause electric shock. While insulating some foot dryers can reduce the risk of electric shock, it also increases production costs.

[0031] It is easy to imagine that in the present invention, the time required for each foot drying operation by the water-absorbing member 300 is relatively short, typically around 10 seconds. Furthermore, the moisture content of each person's feet is generally limited, and the water-absorbing member 300 can be used to dry the feet multiple times after the water is extracted by the air extraction device 200, thus meeting the need for multiple uses within a short period of time. However, people typically bathe at certain times of the day, and drying their feet is generally not necessary during other times, leading to long intervals between foot dryers. The foot dryer provided by the present invention can fully utilize the intervals between baths, namely, during the time between two baths, the air extraction device 200 is activated to extract moisture from the water-absorbing member 300. Due to the long interval, the air extraction device 200 can be operated in a low-power, long-duration mode to complete the task of extracting moisture from the water-absorbing member 300. Because the vacuum device 200 has low power consumption, the required power supply voltage can also be designed to be very low. In a specific implementation, the required power supply voltage for the vacuum device 200 is less than 36V. This allows for safe use in humid environments such as bathrooms. Even if a leakage occurs, electric shock accidents are unlikely, resulting in high safety without increasing production costs. Furthermore, when the vacuum device 200 operates at a low power consumption, it generates little noise. Compared to existing foot dryers that generate a lot of noise, the foot dryer provided by the present invention operates silently.

[0032] Specifically, in some embodiments, the base 100 of the foot dryer provided by the present invention may be equipped with a battery, thereby enabling the battery to power the vacuum device 200 at a voltage of less than 36V. Alternatively, in some embodiments, the base 100 may be equipped with a wireless charging device, which is electrically connected to the vacuum device 200 and powers the vacuum device 200 at a voltage of less than 36V. Thus, wireless charging can be used to power the vacuum device 200 at a voltage of less than 36V. With these arrangements, the foot dryer is highly safe and can be flexibly placed, making it convenient for safe use in environments such as bathrooms.

[0033] When existing foot dryers are used in humid environments, the hot air they deliver carries a lot of moisture, resulting in poor foot drying. Compared to existing foot dryers, the foot dryer provided by the present invention uses the air extraction device 200 to extract moisture from the water absorbent element 300, allowing the water absorbent element 300 to maintain its water absorption properties even in humid environments. Consequently, the water absorbent element 300 can still come into contact with the foot and absorb moisture from the soles of the foot, effectively drying the foot.

[0034] In a specific implementation, the foot dryer provided by the present invention includes a control device electrically connected to an air extraction device. It is conceivable that, in some embodiments, the control device may have a timer switch function, which can periodically turn the air extraction device on or off, thereby ensuring that the absorbent member 300 maintains its water absorbency. In some embodiments, the control device may also be electrically connected to a humidity sensor, which can detect the dryness or wetness of the absorbent member, and the control device can control whether the air extraction device is activated based on the information provided by the humidity sensor. Of course, the foot dryer may also adopt other control methods. For example, in some embodiments, the control device may be electrically connected to a gravity sensor, which can detect whether a person is standing on the absorbent member 300, and the control device can control whether the air extraction device is activated based on the signal provided by the gravity sensor.

[0035] With the above arrangement, the foot dryer provided by the present invention allows people to dry their feet simply by standing on the water absorbing member 300 without any other unnecessary operations, and is simple and quick to use.

[0036] During the specific implementation process, the water-absorbing member 300 can be various water-absorbing materials such as foamed water-absorbing sponges, cotton wool pads, etc. These water-absorbing materials are porous water-absorbing materials, and the moisture of the water-absorbing materials can be extracted by the vacuum device 200. These water-absorbing materials are flexible, and when people stand on the water-absorbing member 300, the water-absorbing member 300 can give people a comfortable feeling.

[0037] Reference Figure 1 and Figure 3It is conceivable that in some embodiments, the air extraction channel includes an air extraction chamber 131 and a first discharge hole 132, the air extraction chamber 131 is set at the air extraction position, the water absorbent member 300 is installed in the air extraction chamber 131, the base 100 is provided with a separation chamber 140, the separation chamber 140 is located below the air extraction chamber 131, and the outer surface of the base 100 is provided with a second discharge hole 111 connected to the separation chamber 140, the air extraction device 200 is installed in the separation chamber 140, the air inlet 2221 of the air extraction device 200 is connected to the first discharge hole 132, and the air outlet 223 of the air extraction device 200 is connected to the separation chamber 140. With the above arrangement, when the vacuum device 200 is in operation, a negative pressure is formed in the vacuum chamber 131, thereby drawing the moisture in the water absorbent member 300 into the vacuum chamber 131 along with the outside air. The water and air are then drawn into the separation chamber 140 by the vacuum device 200, causing the pressure in the separation chamber 140 to be higher than that in the outside, i.e., a positive pressure is formed in the separation chamber 140. Under the positive pressure, the air in the separation chamber 140 can be naturally discharged from the second discharge hole 111, while some of the moisture in the air can be converted into liquid and remain in the separation chamber 140, thereby separating some of the water from the air and reducing the humidity of the discharged air. This prevents the discharged air from carrying a large amount of moisture and being reabsorbed by the water absorbent member 300, thereby affecting the water absorption capacity of the water absorbent member 300.

[0038] It is easy to imagine that, since the foot dryer provided by the present invention can reduce moisture in the air, in addition to using the water absorbing member 300 to dry feet, the foot dryer provided by the present invention can also be used to reduce the air humidity in the environment to achieve a dehumidification function.

[0039] In some embodiments, a drawer-type water tray may be provided in the separation chamber 140, and the water may be poured out by taking out the drawer-type water tray; in other embodiments, the separation chamber 140 may also be connected to a drain pipe, and the water in the separation chamber 140 may be discharged to the bathroom, sewer or other places through the drain pipe.

[0040] Reference Figure 1 、 Figure 4 and Figure 5It is conceivable that, in some embodiments, the exhaust device 200 includes a motor 210 and an exhaust fan 220, the exhaust fan 220 including a fan disc 221 and a fan cover 222, the upper surface of the fan disc 221 being provided with a plurality of guide vanes 2211 arranged in a spiral shape, the fan cover 222 being located above the fan disc 221 and covering all of the guide vanes 2211, the output shaft of the motor 210 being connected to the fan cover 222, wherein an air inlet 2221 is provided on the fan cover 222, and the fan disc 221, the upper cover, and the guide vanes 2211 enclose a plurality of air outlets 223 arranged circumferentially along the fan disc 221. Thus, when the motor 210 is operating, the output shaft of the motor 210 can drive the fan disc 221 to rotate, and the guide vanes 2211 can then be used to centrifugally eject the air and moisture in the exhaust fan 220 from the air outlets 223, thereby achieving the exhaust function. When the water extracted from the water absorbing member 300 by the air extraction device 200 passes through the air extraction chamber 131 or the air extraction fan 220, a portion of the water forms a water flow, which is then thrown into the separation chamber 140 by the air extraction fan 220. Meanwhile, the gaseous water in the air also forms water droplets when it hits the inner wall of the separation chamber 140, thereby separating the water from the air and temporarily retaining it in the separation chamber 140. This arrangement allows for effective water vapor separation.

[0041] Reference Figure 1 、 Figure 4 and Figure 5 It is conceivable that, in some embodiments, the air extraction device 200 includes a water retaining shell 400, which is provided with a water collecting chamber 410 with an open top. The sidewall of the water collecting chamber 410 is at least partially located below the fan disk 221, and the vertical projection of the fan disk 221 is located within the water collecting chamber 410. The lower end of the water retaining shell 400 is provided with a water outlet 420, and the water collecting chamber 410 is connected to the separation chamber 140 through the water outlet 420. During the operation of the air extraction device 200, at least part of the air and moisture centrifugally ejected by the exhaust fan 220 can hit the inner wall of the water collecting chamber 410. Due to the high air pressure in the water collecting chamber 410, the air will leave from the top of the water collecting chamber 410, and the inner wall of the water collecting chamber 410 can intercept some of the moisture in the air, thereby improving the efficiency of water vapor separation.

[0042] Reference Figure 1 、 Figure 4 and Figure 5 It is conceivable that in some embodiments, the bottom wall of the water collecting chamber 410 is provided with a mounting portion 430 protruding upward, the lower surface of the water retaining shell 400 is provided with a mounting cavity 440 extending to the mounting portion 430, the upper side wall of the mounting cavity 440 is provided with a relief hole 450, the motor 210 is mounted in the mounting cavity 440, and the output shaft of the motor 210 is passed through the relief hole 450. With this arrangement, the mounting portion 430 can protect the motor 210 and provide a waterproof effect.

[0043] Reference Figure 1 It is conceivable that, in some embodiments, the second discharge hole 111 is vertically greater than the air outlet 223. The above arrangement can prevent the exhaust fan 220 from directly throwing air and moisture to the second discharge hole 111, so that the air in the separation chamber 140 is discharged at a positive pressure.

[0044] It should be noted that the above-mentioned exhaust device 200 can also be set up in other ways. For example, the exhaust device 200 can include a blower, the air inlet of the blower is connected to the first exhaust port, and a water absorption filter is set at the air outlet of the blower to reduce the humidity of the air discharged by the blower.

[0045] Reference Figure 1 and Figure 3 It is conceivable that in some embodiments, a support plate 500 is disposed within the air extraction chamber 131, with a plurality of ventilation holes 510 disposed thereon. The water absorbent member 300 is also placed on the support plate 500. Thus, the support plate 500 can support the water absorbent member 300, allowing the water absorbent member 300 to support the foot. A gap is provided between the support plate 500 and the bottom wall of the air extraction chamber 131. Thus, when the air extraction device 200 is in operation, a negative pressure is generated between the support plate 500 and the bottom wall of the air extraction chamber 131, thereby extracting moisture from the water absorbent member 300.

[0046] A support portion 133 is protruded from the bottom wall of the air extraction cavity 131 , and the support portion 133 abuts against the support plate 500 . Thus, the support portion 133 can support the support plate 500 to improve the bearing capacity of the support plate 500 .

[0047] Reference Figure 1 and Figure 3 It is conceivable that in some embodiments, the base 100 includes a housing 110, a bottom cover 120, and an air extraction chamber 130. The housing 110 is annular, the bottom cover 120 is disposed at the lower end of the housing 110, and the air extraction chamber 130 is detachably mounted on the upper end of the bottom cover 120. The housing 110, the air extraction chamber 130, and the bottom cover 120 together form a separation chamber 140, and the air extraction chamber 131 is disposed in the air extraction chamber 130. The above arrangement can facilitate the production and processing of the base 100 and also facilitate the subsequent maintenance of the air extraction device 200.

[0048] Reference Figure 1 and Figure 3 It is conceivable that in some embodiments, the absorbent member 300 is detachable, so that when the absorbent member 300 becomes dirty, the absorbent member 300 can be removed for cleaning, and if the absorbent member 300 is damaged, the absorbent member 300 can also be replaced.

[0049] Reference Figure 1It is conceivable that, in some embodiments, the water absorbent member 300 is horizontally disposed at the air extraction position so that people can stand stably on the water absorbent member 300 .

[0050] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the scope of the present invention.
