Technical Field

[0001] This invention belongs to the field of smart home, specifically relating to a foot bath device including a medicine dispenser. Background Technology

[0002] In recent years, smart homes have gained attention. The core of smart homes is to meet people's lifestyle needs, ideally through interconnected systems to satisfy multiple requirements. Foot baths are a common health practice, but traditional methods have some inconveniences, such as difficulty in maintaining water temperature and the need for manual water refilling. Therefore, a medicinal foot bath device that can meet people's needs is needed.

[0003] In the prior art, Chinese patent CN 218106358 U discloses a foot bath device including a drug dispensing mechanism. This device has a container for storing the drug and a drug dispensing port located at the bottom of the container. The opening and closing of the drug dispensing port is controlled by a drive assembly. This device is only suitable for liquid drugs such as medicinal wines that evaporate quickly. Summary of the Invention

[0004] This invention aims to provide a dosing device suitable for foot bath devices, capable of dispensing various forms of foot bath medications such as medicinal wine, medicinal powder, and traditional Chinese medicine. Furthermore, to facilitate user observation and control of the dosage during the foot bath, the dosing device should be positioned at the top of the foot bath device, dispensing medication from top to bottom.

[0005] This invention is achieved through the following technical solution: A dosing device for foot bath equipment includes a medicine storage compartment for storing foot bath medicine, characterized in that the dosing device further includes: A valve is located at the bottom of the medicine storage compartment; the valve constitutes a control structure for dispensing the foot bath medicine, and the opening degree of the valve is positively correlated with the outlet size of the foot bath medicine dispensing channel; A slider, which drives the valve to open and close; A lead screw, which engages with the slider via a threaded pair, wherein the feed direction of the lead screw is consistent with the movement direction of the valve component; A dosing motor, wherein the dosing motor and the lead screw transmit power through a linkage; The dosing motor and the lead screw are located on opposite sides of the same area of ​​the drug storage chamber. The dosing motor, the lead screw, the drug storage chamber, and the linkage form an active area. The movement path of the valve when it is opened and closed is part of the active area.

[0006] The dosing device controls the opening degree of the medicine storage chamber by adjusting the valve components through the dosing motor, thereby controlling the total amount of medicine dispensed. Considering that rapid or large-volume drug dispensing may cause water to splash out, the dosing device is designed with an active area to accommodate the valve components. During rapid or large-volume dispensing, the space of the active area is entirely used to accommodate the valve components, which can then block the splashing water, preventing water from the foot bath device from splashing onto the external ground or into the dosing motor.

[0007] Preferably, the output end of the dosing motor is located at the end furthest from the drug storage chamber. When the output end of the dosing motor is located at the far end relative to the drug storage chamber, the range of the active area is correspondingly expanded, and the valve component has a longer movement path, making it easier for the user to make more precise adjustments to the position of the valve component.

[0008] Preferably, the output shaft of the dosing motor is parallel to the feed direction of the lead screw, and the linkage includes a synchronous belt chain that connects the output end of the dosing motor and the lead screw. This parallel arrangement improves the transmission efficiency of the linkage and maximizes the space utilization of the moving area, allowing sufficient space for valve components without creating redundant space.

[0009] The present invention also proposes a foot bath device, comprising a tank for containing feet and foot bath liquid, and further comprising the dosing device described in any of the above claims.

[0010] Preferably, the dosing motor is located at the top of the side wall of the tank, and the output shaft of the dosing motor is parallel to the side wall.

[0011] Preferably, the linkage is located at the top of the side wall of the groove, and the extension direction of the linkage is parallel to the side wall.

[0012] When the dosing motor or linkage is attached to the top of the side wall, the dosing device is also located at the edge of the tank, and the valve can also be attached to the side wall of the tank to the greatest extent, further improving the space-saving effect and the water splash blocking effect.

[0013] Preferably, the foot bath device includes a heater disposed in the lower inner part of the tub.

[0014] Preferably, the foot bath device further includes a temperature sensor, the temperature measuring area of ​​which is the lower inner part of the tank; the heater uses the temperature signal detected by the temperature sensor as the standard for starting and stopping.

[0015] Preferably, the foot bath device includes a drain outlet and a drain valve located on the lower part of the side wall of the tank.

[0016] Preferably, the drain valve is connected to a drain valve drive; the drain valve drive includes a motor for driving.

[0017] Preferably, the foot bath device includes multiple sets of massage rollers, which are disposed at the bottom of the tank.

[0018] This invention proposes a dosing device for foot bath devices, suitable for various forms of foot bath medications such as medicinal wine, medicinal powder, and traditional Chinese medicine. The dosing device features a screw-slider structure to control the opening degree of the valve, allowing for adjustment of the medication dispensing speed and more accurate dosage control. Mounted on top of the foot bath device, the dosing device utilizes the movable area formed between the screw and the dosing motor as the movement path for opening and closing the valve, saving space occupied by the dosing device on top of the foot bath device. The foot bath device itself also incorporates a temperature control system to maintain the temperature during the foot bath process; the temperature measuring position is located inside the lower part of the tank, ensuring the measured temperature is closer to the temperature felt by the feet, improving the foot bath experience. Massage rollers are installed at the bottom of the foot bath device, providing massage during the foot bath and enhancing the medicinal bath effect. Furthermore, the foot bath device is equipped with an automatically opening and closing drain, allowing for effortless and convenient drainage after the foot bath. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Those skilled in the art will be able to implement the present invention based on these descriptions. Furthermore, the embodiments of the present invention described below are generally only some, not all, of the embodiments of the present invention. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0022] This embodiment is a functional structure scheme designed by college students based on the concept of intelligent home.

[0023] Please see Figure 1 The dosing device 1 has a compact design. The figure shows a three-dimensional view of the dosing device 1. For ease of description, the axis of the lead screw 104 will be referred to as the left-right direction, and the side of the lead screw 104 near the medicine storage chamber 101 will be referred to as the left side; the side of the linkage 106 near the lead screw 104 will be the front side, and the side near the dosing motor 105 will be the rear side. The top surface of the medicine storage chamber 101 is a rotating and opening cover 108, suitable for adding various forms of medicinal bath materials such as medicinal wine, medicinal powder, and whole Chinese medicinal herbs. The bottom surface of the medicine storage chamber 101 is a valve 102. Moving the valve 102 to the right corresponds to opening the medicine storage chamber 101, and moving the valve 102 to the left corresponds to closing the medicine storage chamber 101. The greater the opening degree of the valve 102, the larger the outlet of the foot bath medicine dispensing channel; the smaller the opening degree of the valve 102, the smaller the outlet of the foot bath medicine dispensing channel. The opening and closing degree of valve 102 is controlled by dosing motor 105, lead screw 104, slider 103, and linkage 106. The user controls the total dosage by adjusting the opening and closing degree of valve 102. Valve 102 is directly connected to slider 103, which is connected to lead screw 104 via a threaded connection, allowing it to slide left and right along the axis of lead screw 104. The feed direction of lead screw 104 to slider 103 is the same as the movement direction of valve 102. Both lead screw 104 and dosing motor 105 are located on the right side of drug storage chamber 101, arranged opposite each other, with lead screw 104 at the front and drug storage chamber 101 at the rear. The output end of dosing motor 105 is located at its right end, away from drug storage chamber 101; the output shaft of dosing motor 105 is parallel to the feed direction of lead screw 104, and power is transmitted between them via linkage 106. In this embodiment, the linkage 106 is a synchronous belt chain structure, with the rack perpendicular to the feed direction of the lead screw 104. The lead screw 104, the medicine storage chamber 101, the dosing motor 105, and the linkage 106 enclose an active area 107, which accommodates part of the movement path of the valve 102 when it opens and closes. Rapid or large-volume drug administration may cause water splashing; therefore, the dosing device 1 is designed with an active area 107 to accommodate the valve 102. The output shaft of the dosing motor 105 is parallel to the feed direction of the lead screw 104, which improves the transmission efficiency of the linkage 106 and maximizes the space utilization of the active area 107, fully accommodating the valve 102 without creating redundant space. During rapid or large-volume administration, the space of the active area 107 is entirely used to accommodate the valve 102, which effectively blocks splashing water, preventing water from the foot bath device from splashing onto the external ground or into the dosing motor 105.

[0024] Please see Figure 2The basic structure of this foot bath device includes a tank 2 for accommodating feet and foot bath liquid, with the dosing device 1 integrally mounted on top of the tank 2. A dosing motor 105 is located on top of one side wall of the tank 2, with its output shaft parallel to the side wall. A linkage 106 is located on top of the side wall adjacent to the location of the dosing motor 105, and its extension direction is also parallel to the side wall. At this point, the dosing device 1 is positioned at the edge of the tank 2, and the valve 102 is as close as possible to the side wall of the tank 2, further enhancing space-saving and splash-blocking effects.

[0025] Please see Figure 2 The foot bath device includes an automatic drainage structure. A drain outlet 401 and a drain valve 402 are located at the bottom of the side wall of the tank 2. The opening and closing of the drain valve 402 is powered by a drain valve drive component 403. In this embodiment, the drain valve drive component 403 is a rack and pinion structure, and the rotation of the gear is controlled by a motor. When the motor starts, the gear rotates forward, and the rack meshing with the gear drives the drain valve 402 upward, opening the drain outlet 401; when the gear rotates in the reverse direction, the rack meshing with the gear drives the drain valve 402 downward, closing the drain outlet 401. The drain valve drive component 403 is located on the outer side of the side wall of the tank 2 to prevent water splashing.

[0026] Please see Figure 3 The foot bath device includes a temperature sensor 302 and a heater 301 for temperature control. Both the temperature sensor 302 and the heater 301 are located at the bottom of the inner side wall of the tank 2. When the temperature sensor 302 detects that the water temperature is lower than the set value, it will automatically start the heater 301. After the water temperature reaches the set value, the heater 301 will be turned off to ensure the medicinal bath effect.

[0027] Please see Figure 3 The foot bath device includes massage rollers 5. The massage rollers 5 are located on the bottom inner side of the tank 2, allowing the user to massage their feet while taking a medicinal bath.

[0028] When using this device, the user can first start the heater 301 to preheat the foot bath liquid in the tank 2. During the foot bath, if the liquid temperature in the tank 2 is lower than the set value, the heater 301 will automatically start to reheat and maintain the water temperature. The user can first put the foot bath herbs into the medicine storage chamber 101, and after the water temperature is suitable, start the medicine dosing motor 105 and open the valve 102. By controlling the opening degree of the valve 102, the user can adjust the speed of medicine dosing and more accurately control the amount of medicine added. The user can also use the massage rollers 5 at the bottom of the tank 2 for foot massage to enhance the foot bath experience.
