DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0019] On the contrary, the present application covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present application as defined by the claims. Further, in order to make the public have a better understanding of the present application, some specific details are described in detail in the detailed description of the present application below. Those skilled in the art can fully understand the present application without the description of these details.

[0020] Figure 1 It is a schematic diagram of the three-dimensional structure of an exemplary foot bathing device according to some embodiments of the present application. Figure 2 It is a schematic cross-sectional structural diagram of an exemplary foot bathing device according to some embodiments of the present application.

[0021] like Figure 1 and Figure 2 As shown, the foot bath device 100 may include a main body 110 and a foot bath 120. The foot bath 120 may be used to store water and accommodate the feet of a foot bather. In addition to the foot bathing function, the foot bath device 100 may also provide one or more functions such as Chinese medicine foot bathing, negative oxygen ion foot bathing, and foot massage.

[0022] In some embodiments, a negative oxygen ion generating device 111 and a steam generating device 112 may be provided in the main body 110 , and a negative oxygen ion outlet 125 , a steam outlet 126 and a traditional Chinese medicine extraction box 122 may be provided in the footbath 120 .

[0023] The negative oxygen ion generating device 111 can be used to generate negative oxygen ions (such as gas with negative oxygen ions), and the negative oxygen ions are transported to the footbath 120 through the negative oxygen ion outlet 125. In some embodiments, the negative oxygen ion outlet 125 may include one or more. The negative oxygen ion outlet 125 may be arranged at the bottom and / or side of the footbath 120. In some embodiments, a microporous releaser 121 is provided at the negative oxygen ion outlet. The microporous releaser 121 may be provided with multiple outlets with small pore sizes (such as pore sizes less than 1 mm, 1 micron, 50 nanometers, 10 nanometers, etc.). Negative oxygen ions can pass through the microporous releaser 121 and be released from the multiple small pore outlets of the microporous releaser 121. In some embodiments, the microporous releaser 121 may include one or more nanostones, air refiners, etc. In some embodiments, in addition to refining the size of gas bubbles, the microporous releaser 121 may also have the functions of anti-blocking and silencing release. In some embodiments, the microporous releaser 121 may cover and be fixed at the negative oxygen ion outlet. In some alternative embodiments, the microporous releaser 121 may also be provided with a gas inlet, through which negative oxygen ions can enter the microporous releaser and be released from multiple small-aperture outlets. In some embodiments, in order to improve the sealing performance of the interface between the negative oxygen ion outlet 125 and the microporous releaser, a sealing ring (not shown) may be provided at the interface, or the interface may be sealed by a sealant. By providing the microporous releaser 121 at the negative oxygen ion outlet, the negative oxygen ion gas bubbles entering the footbath 120 can be made smaller, thereby effectively increasing the contact area between the negative oxygen ions and the water and increasing the water solubility of the negative oxygen ions. In some embodiments, the size of the microporous releaser 121 may be comparable to the size of the negative oxygen ion outlet 125. In some embodiments, the size of the microporous releaser 121 may also exceed the size of the negative oxygen ion outlet 125.

[0024] In some embodiments, the negative oxygen ion generating device 111 is disposed inside the main body 110, and the generated negative oxygen ions are transported to the negative oxygen ion outlet 125 through the negative oxygen ion transport pipe 114. In some embodiments, the negative oxygen ion generating device 111 may include an oxygen supplier, a negative oxygen ion generating chamber, and a negative ion generator. For more details about the negative oxygen ion generating device 111, please refer to Figure 3 and its related description.

[0025] The steam generating device 112 can be used to generate hot steam, and the hot steam is delivered to the footbath 120 through the steam outlet 126. In some embodiments, the steam outlet 126 may include one or more. The steam outlet 126 may be arranged on the side and / or bottom of the footbath 120. In some embodiments, a steam releaser (not shown) is provided at the steam outlet, and the steam releaser includes a plurality of steam release outlets. In some embodiments, the steam releaser may be a microporous release, and the pore size of the micropores may be less than 1 mm, 1 micron, 50 nanometers, 10 nanometers, etc. In some embodiments, the steam releaser at the steam outlet may also include a steam release muffler for eliminating the noise generated by the release of steam in the water. In some embodiments, in order to improve the sealing performance of the interface between the steam outlet and the steam releaser, a sealing ring may be provided at the interface, or the interface may be sealed by a sealant. By providing a steam releaser, the size of the hot steam bubbles released can be effectively reduced, so that the hot steam focuses on the Chinese medicine closer to the steam release outlet, and when the hot steam diffuses outward again, the temperature drops rapidly, thereby effectively avoiding hot steam scalding the feet.

[0026] In some embodiments, the Chinese medicine extraction box 122 covers the steam outlet for filling Chinese medicine and extracting Chinese medicine using hot steam. In some embodiments, the bottom of the Chinese medicine extraction box is fixed on the steam outlet 126 of the footbath 120. Among them, the fixing method may include but is not limited to snap-on, glue-on, threaded connection and the like. Preferably, the bottom of the Chinese medicine extraction box 122 can be fixed to the steam outlet by a detachable connection (such as threaded connection, snap-on), so that the Chinese medicine extraction box is easy to disassemble and clean. In some embodiments, the bottom and side of the Chinese medicine extraction box 122 have a porous structure. Among them, the bottom pores correspond to the steam outlet 126 (or steam releaser) to facilitate the entry of hot steam; the side pores of the Chinese medicine extraction box 122 can facilitate the water heated by high-temperature steam and / or the extracted Chinese medicine essence to flow out of the Chinese medicine extraction box into the footbath. In some embodiments, the Chinese medicine extraction box 122 may further include a box cover 123, which may be closed after the Chinese medicine is placed in the Chinese medicine extraction box to prevent the Chinese medicine residue from floating out and affecting the foot bathing experience; at the same time, it may prevent the user's hands and feet from accidentally being put into the Chinese medicine extraction box 122 and being scalded. In some embodiments, the footbath 120 may further include a heat insulation cover (not shown), which may be detachably covered on the outside of the Chinese medicine extraction box 122 to prevent the feet from being exposed to hot steam and causing scalding.

[0027] In some embodiments, the steam generating device 112 is disposed inside the main body 110 to generate hot steam. In some embodiments, the steam generating device 112 may include a heating component, a steam boiler, a water storage tank, etc. Among them, the heating component can be any device for heating, providing a heat source for water vaporization into water vapor; the steam boiler is the main place for generating hot steam, and the hot steam generated by the steam boiler is transported to the footbath 120 along the pipeline through the steam outlet 126 and the Chinese medicine extraction box 122. In some embodiments, the temperature range of the generated hot steam can be 100-110°C (such as 100°C, 103°C, 105°C, 108°C, etc.). The hot steam generated by the steam generating device 112 can be transported to the footbath 110 through the steam delivery pipeline 115, on the one hand, for extracting the Chinese medicine placed in the Chinese medicine extraction box 122, and on the other hand, for heating the water in the footbath 120. By arranging the heating component in the steam generating device 112 inside the main body 110 and separating it from the footbath 120, the heating process can be made safe and the risk of leakage can be effectively avoided.

[0028] The present application can effectively improve the extraction effect of the Chinese medicine essence by delivering hot steam to the inside of the Chinese medicine extraction box 122, thereby helping to enhance the health-preserving effect of Chinese medicine foot bathing.

[0029] In some embodiments, the footbath 120 can be made of heat-resistant plastic, wood, or a combination of the two materials. In some embodiments, the footbath 120 can be any shape with an upper opening structure. The footbath 120 can also be provided with a drainage hole for discharging sewage after foot soaking. In some embodiments, the footbath 120 can also include a massage roller 124. The massage roller 124 can be arranged in the left and right parts of the bottom of the footbath 120, and the left and right parts correspond to the footrest positions of the left and right feet respectively. The massage roller 124 can include a foot massage type and / or an electric massage type. Among them, the foot massage type has no external power source, and the massage effect is achieved by rotating the roller by friction with the foot; the electric massage type massage roller is driven to rotate by the power device in the main body of the foot bathing equipment, making foot soaking easier.

[0030] In some embodiments, the main body 110 may also include, but is not limited to, a controller 113, a temperature sensor (not shown), a water level sensor (not shown), a display screen (not shown), a pipeline (e.g., a steam delivery pipeline 115, a negative oxygen ion delivery pipeline 114), or a combination of one or more thereof. The main body 110 can realize various functional operations in the footbath 120, such as negative oxygen ion generation, negative oxygen ion concentration control, steam generation, steam temperature control, electric massage roller speed, water tank water level alarm, water temperature control in the footbath, foot soaking time control, footbath information display, etc. The main body 110 has a certain space inside, which can accommodate the installation of various functional devices required by the present application.

[0031] The controller 113 can control and adjust parameters related to the foot bathing function, such as foot bathing time, foot bathing temperature, control and adjust the negative oxygen ions released (including generation and stop, negative oxygen ion concentration, etc.), control and adjust hot steam (including hot steam generation and stop, hot steam temperature), water tank water level monitoring (when it is lower than a certain threshold, the alarm light is on) and electric massage roller speed, etc. In some embodiments, the controller 113 may include a monitoring module and a control module, and the monitoring data of the monitoring module is transmitted to the control module, so that the control module intelligently regulates the foot bathing device 100 to work according to the set parameters. Among them, the monitoring module may include various sensors, such as temperature sensors, pressure sensors, negative oxygen ion concentration sensors, water level sensors and other devices, which are used to monitor the relevant parameters of each part in the main body 110 and the foot bath 120; the control module can control and adjust the relevant devices of the foot bathing device 100 to work accordingly to meet the functional foot bathing needs. For example, the temperature sensor is used to detect the water temperature in the footbath 120, and the control module in the controller 113 is used to control the steam generating device 112 according to the water temperature in the footbath, so that the temperature in the footbath fluctuates within a small range (such as ±2°C) including a preset parameter value (such as 40°C). Through the control of the controller 113, the foot bathing function setting of the user of the footbath device 100 of the present application can be made more personalized and intelligent.

[0032] The display screen (not shown) can display information related to foot soaking for reference by foot soaking users. In some embodiments, the content displayed on the display screen may include but is not limited to water temperature, negative oxygen ion concentration, foot soaking time, water level in the water tank, suggestions or reminders (for example, recommended foot soaking time, reminder to add water to the water tank), etc. Users can set parameters according to the information displayed on the display screen to meet diverse health needs.

[0033] In some embodiments, a certain pipe section of the negative oxygen ion delivery pipe 114 and the steam delivery pipe 115 can be designed to be U-shaped to prevent the water in the footbath 120 from flowing back.

[0034] In some embodiments, Figure 1-2 As shown, the footbath 120 and the main body 110 can be an integral structure. In some alternative embodiments, the footbath and the main body can be detachably connected. When the footbath 120 and the main body 110 are detachably connected, the upper part of the main body 110 can be adapted to the bottom contour of the footbath 120. Thus, when the footbath is installed on the main body, the relevant parts of the footbath 120 (such as the negative oxygen ion outlet 125, the steam outlet 126, etc.) can be automatically aligned with the relevant parts on the main body (such as the negative oxygen ion generating device 111, the steam generating device 112, etc.).

[0035] It should be noted that the above description of the footbath device is only for illustration and explanation, and does not limit the scope of application of the present application. For those skilled in the art, various modifications and changes can be made to the footbath device under the guidance of the present application. However, these modifications and changes are still within the scope of the present application. For example, the footbath device may not be limited to Figure 1-2 As another example, one or more components in the main body or footbath (such as a water level sensor, a display screen, a massage roller 124, etc.) can be omitted.

[0036] Figure 3 Schematic diagram of the structure of an exemplary negative oxygen ion generating device according to some embodiments of the present application. Figure 3 As shown, the negative oxygen ion generating device 111 may include an oxygen supplier 310 , a negative oxygen ion generating chamber 320 and a negative ion generator 330 .

[0037] The oxygen supply device 310 is connected to the air inlet 324 of the negative oxygen ion generating chamber 320, and is used to provide air (oxygen concentration is 21%) or a mixed gas containing a higher oxygen concentration (such as 30%, 40%, 50%, etc.) to the negative oxygen ion generating chamber 320. In some embodiments, the oxygen supply device 310 includes an air pump 311 and / or an oxygen generator 312. Among them, the air pump 311 can be used to provide air to the negative oxygen ion generating chamber. The oxygen generator 312 can provide high-concentration oxygen (such as oxygen concentration of 60%, 80%, etc.) to the negative oxygen ion generating chamber. The oxygen concentration of the gas provided by the oxygen supply device 310 to the negative oxygen ion generating chamber 320 can be effectively controlled by combining the air pump 311 and the oxygen generator 312. When the oxygen concentration of the gas provided by the oxygen supply device 310 is higher, the concentration of negative oxygen ions generated by the negative oxygen ion generating device 111 is also higher. Using high-concentration negative oxygen ions to soak feet can enhance the health effect to a certain extent. In addition, users can also adjust the concentration of negative oxygen ions by themselves.

[0038] The negative oxygen ion generating chamber 320 is connected to the oxygen supplier 310 and is the main place for generating negative oxygen ions. In some embodiments, the negative oxygen ion generating chamber 320 includes a mixing chamber 321, a partition 322, a buffer chamber 323, an air inlet 324 and an air outlet 325. The mixing chamber 321 and the buffer chamber 323 are separated from each other by the partition 322. The partition 322 is provided with a through hole, and the negative ion generator 330 is arranged at the through hole. The through hole can be arranged at any position on the partition 322. For example, at Figure 3In the illustrated embodiment, the through hole may be provided at the center of the partition 322. In some embodiments, an air inlet 324 is provided on the side wall and / or the bottom of the mixing chamber 321 for delivering the gas prepared by the oxygen supplier 310 to the mixing chamber 321. The air delivered from the air inlet 324 is fully mixed in the mixing chamber 321, so that the oxygen concentration in any space in the mixing chamber 321 remains uniform, thereby ensuring the stability of the concentration of the generated negative oxygen ions. The partition 322 separates the mixing chamber 321 from the buffer chamber 323, and the air in the mixing chamber 321 can be delivered to the buffer chamber 323 through the through hole provided on the partition 322. In the embodiment of the present application, the negative ion generator 330 (such as an ionization head) is arranged near the through hole on the partition 322, so that the gas entering the buffer chamber 323 through the through hole passes through the negative ion generator 330 as much as possible, thereby obtaining an efficient and stable ionization effect. Among them, the size of the through hole can be less than or equal to the outline size of the ionization head of the negative ion generator 330. In some embodiments, the ionization head of the negative ion generator 330 can be close to the through hole to obtain a better ionization effect. The setting of the buffer chamber 323 can not only improve the ionization efficiency of the incoming oxygen (for example, secondary ionization, tertiary ionization, multiple ionization, etc.), but also maintain the negative oxygen ion concentration balance in any space of the buffer chamber 323. In some embodiments, the buffer chamber 323 is provided with an air outlet 325, and the gas passing through the negative oxygen ion generating chamber 320 is discharged through the air outlet 325 and transported to the footbath 120 through the negative oxygen ion outlet 125.

[0039] The beneficial effects that may be brought about by the embodiments of the present application include but are not limited to: (1) it is possible to achieve negative oxygen ion foot bathing, effectively improving the health care function of foot bath equipment; (2) it is possible to achieve Chinese medicine foot bathing, further improving the health care ability of foot bath equipment; (3) it is possible to achieve controllable regulation of the negative oxygen ion content in the foot bath basin; (4) it is possible to perform high-temperature extraction of Chinese medicine, ensuring the rapid release of the effective ingredients of Chinese medicine, thereby improving the disease prevention and health care effect of foot bathing; (5) by heating the water body with steam, water and electricity separation is achieved, which can protect the safety of users. It should be noted that different embodiments may produce different beneficial effects. In different embodiments, the beneficial effects that may be produced may be any one or a combination of the above, or any other possible beneficial effects.

[0040] Regarding the effects of negative oxygen ions, the book Modern Physical Therapy edited by Chen Jingzao points out that normal red blood cells and colloidal particles in the blood carry negative charges, and they repel each other and maintain a certain distance. However, diseased and aged red blood cells carry positive charges due to the competition for electrons. Due to the attraction between positive and negative, the red blood cells are condensed into clusters. Negative ions can effectively repair the membrane potential of aged cells, causing them to become normal negatively charged cells. The negative repulsion between negative and negative effectively reduces blood viscosity and slows down erythrocyte sedimentation. At the same time, negative oxygen ions can strengthen the negative polarity trend of colloidal particles in the blood, increase the colloidal stability of plasma proteins, and maintain the normal and healthy state of the blood. This shows the magical effect of negative oxygen ions in maintaining blood vessels.

[0041] The biological effects of negative oxygen ions may include but are not limited to:

[0042] 1) Blood pressure lowering effect: negative ions → monoamine oxidase (MAO) → oxidative deamination → decreases the concentration of 5-HT, catecholamines, and norepinephrine, thus playing a blood pressure lowering role;

[0043] 2) Stimulate hematopoietic function: normalize blood components, negative ions → blood, increase red blood cell repulsion → slow down erythrocyte sedimentation rate, negative ions → spleen function ↑ (enhanced), red blood cells and blood calcium ↑ (increase);

[0044] 3) Promote the biological redox process of tissue cells and remove positively charged free radicals in the blood;

[0045] 4) Bactericidal effect and enhancing immune function.

[0046] The foot bath equipment of some embodiments of the present application can allow a sufficient amount of small-particle negative oxygen ions to enter the human blood circulation through the foot capillaries, producing physical therapy and health care effects. The actual application of this equipment shows that a sufficient amount of small-particle negative oxygen ions in the blood are effective in promoting wound healing of sores, improving insomnia, and lowering blood pressure.

[0047] The foot bath equipment of some embodiments of the present application generates small-particle negative oxygen ions through negative ion converter technology, and forms a negative oxygen ion airflow with stable concentration through a specially constructed air-negative oxygen ion mixing chamber structure (such as negative oxygen ion generating chamber 320), which is blown into the water basin through the nano-fine pore structure to ensure full dissolution, making it a high-concentration negative oxygen ion water. At the same time, the water in the bucket is heated to 40-45 degrees by steam heating, so that the pores of the feet are opened, and the high-concentration small-particle negative oxygen ions in the water can penetrate the thinner surface layer of the foot skin, immerse into the rich capillaries of the foot, and then enter the human blood circulation. The heated water can speed up the blood circulation of the human body and enhance the absorption effect. The entire equipment structure can ensure that a sufficient amount of small-particle negative oxygen ions can enter the whole body's blood circulation, producing rehabilitation and therapeutic effects (for example, lowering blood pressure, scavenging free radicals, sterilizing, enhancing immunity, etc.).

[0048] When the negative ion converter (for example, the negative ion generator 330) is working, it generates a high-voltage negative electric field, which is proportional to the concentration of small-particle negative oxygen ions. In the case of unreliable grounding, this electric field will charge the metal heat-conducting parts in the basin, causing the water to also generate static voltage, thereby affecting safety and health. Therefore, it is not appropriate to use direct heating methods such as resistance wires and PTCs that rely on metal parts for heat transfer. The foot bath equipment of some embodiments of the present application introduces a steam generator (such as the steam generating device 112), and steam is introduced through a pipeline to heat the soaking basin (such as the foot bath basin 120), isolating the direct connection between the soaking basin and the heated heat-conducting metal parts, ensuring the safety of the immersion process, and enabling the negative ion converter (such as the negative ion generator 330) and the heating device (such as the heating device of the steam generating device 112) to be safely integrated in a small space, and having the practicality of the product.

[0049] The negative oxygen ion generating mixing chamber structure (such as the negative oxygen ion generating chamber 320) enables the air to generate a sufficiently stable airflow when flowing through the negative oxygen ion generating electrode. After the air is ionized by the electric field in the cavity, unstable flow changes will occur. This secondary mixing chamber structure (such as the mixing chamber-buffer chamber) can ensure the stable flow of gas, thereby generating more and more stable negative oxygen ion airflow.

[0050] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
