[0035] Figure 1 schematically illustrates a foot massager according to one embodiment. Figure 2 illustrates a cross-section of a foot massager according to one embodiment. Figure 3 is a control block diagram of a foot massager according to one embodiment.

[0036] Referring to FIGS. 1 to 3, the foot massager (10) is a device that can help with falling asleep by easily implementing the effect of a foot bath without discomfort even when worn for a long time.

[0037] A foot massager (10) may include a main body (30) that wraps around the user's foot (1) and ankle (2), and a control box (20) provided with a pump unit (40) and an air supply unit (50) for controlling the operation of the main body (30).

[0038] The main body (30) may be provided in the form of a shoe that covers only the user's ankle (2) so that the user does not feel uncomfortable or stuffy when wearing it for a long time. A receiving portion (31) for receiving the user's foot (1) and ankle (2) may be provided inside the main body (30).

[0039] The main body (30) may include a plurality of expandable and contractible air cells (32). The plurality of air cells (32) may be configured to expand and contract on a surface forming the receiving portion (31) of the main body (30). The plurality of air cells (32) may expand and contract by receiving air pressure from the pump portion (40).

[0040] The pump unit (40) can provide and maintain a preset pressure to a plurality of air cells (32). The pump unit (40) can be provided in the control box (20). The pump unit (40) can be connected to a plurality of air cells (32) via a cable (11).

[0041] The cable (11) may include hoses for power, communication, fluid communication, etc. The cable (11) may be provided with hoses for fluid communication between the pump unit (40) and a plurality of air cells (32).

[0042] The pump unit (40) may include an air pump (41) that supplies air, and a plurality of valves (42) that control the air supplied from the air pump (41) to a plurality of air cells (32). The pump unit (40) may be operated according to a control signal of the control unit (70).

[0043] The air pump (41) can supply air to a plurality of air cells (32) or suck air from a plurality of air cells (32).

[0044] A plurality of valves (42) may be provided in a number corresponding to a plurality of air cells (32). The plurality of valves (42) may include solenoid valves that open and close passages that are respectively connected to the plurality of air cells (32). When the valve (42) is opened, the passages of the corresponding air cells (32) and the air pump (41) are connected, so that the air cells (32) can expand and contract, and when the valve (42) is closed, the passages of the corresponding air cells (32) and the air pump (41) are blocked, so that the air cells (32) can be maintained in an expanded state. Although not shown, a passage for supplying air pressure to the plurality of air cells (32) may be provided in the main body (30).

[0045] The main body (30) may include a plurality of protrusions (34) protruding from the bottom surface (33) of the receiving portion (31). The plurality of protrusions (34) may come into contact with the user's soles and / or toes. The plurality of protrusions (34) may provide a meridian massage effect to the user's soles and / or toes when the air cell (32) expands and contracts.

[0046] A plurality of protrusions (34) may protrude from the upper surface of a euro pad (35) provided on the bottom of the receiving portion (31) of the main body (30). The euro pad (35) may be positioned on the upper surface of the air cell (32). The euro pad (35) may have a shape corresponding to the bottom surface (33) of the receiving portion (31).

[0047] An air path (36) may be provided inside the euro pad (35). The air path (36) may be in fluid communication with an air supply unit (50). The euro pad (35) may be provided with a plurality of air discharge ports (37) for discharging air flowing in the air path (36) to a receiving unit (31).

[0048] The plurality of air outlets (37) may be positioned at a lower height than the plurality of protrusions (34). This is to prevent the air outlets (37) from being blocked when the plurality of air cells (32) expand while inducing smooth air flow on the bottom surface (33) of the receiving portion (31). That is, when there are no plurality of protrusions (34), when the plurality of air cells (32) expand, the air outlets (37) of the euro pad (35) come into close contact with the soles (3) of the user's feet, making it difficult to discharge air toward the receiving portion (31). In addition, since the space through which fluid can flow between the soles (3) of the user's feet and the bottom surface (33) of the receiving portion (31) is narrow, air circulation does not occur within the receiving portion (31).

[0049] The air supply unit (50) can supply temperature-controlled air to the air passage (36). The temperature-controlled air can include cold air.

[0050] The air supply unit (50) can be installed in the control box (20). The air supply unit (50) can include a thermoelement (51) and a fan (52).

[0051] The thermoelectric element (51) absorbs or generates heat by the Peltier effect, which creates a temperature difference at the junction of two different conductors when current flows, so that one side becomes cold and the other side releases heat. The air supply unit (50) can provide air cooled by heat absorption to the air passage (36) through the fan (52). The air supply unit (50) can be in fluid communication with the air passage (36) through a hose provided in the cable (11).

[0052] The main body (30) may be provided with a heating unit (60) to provide a feeling of warmth to the user. The heating unit (60) may be operated according to a control signal from the control unit (70). The heating unit (60) may be configured to increase the temperature inside the receiving unit (31).

[0053] According to one embodiment, the heating unit (60) may include a heating wire (61) provided on the euro pad (35). The heating wire (61) may be positioned below the protrusion (34). The heating wire (61) may be positioned adjacent to the lower side of the protrusion (34). The heating wire (61) may be positioned directly below the protrusion (34). The heat generated from the heating wire (61) may first heat the protrusion (34) and then provide heat to the inside of the receiving unit (31). Through this, rapid heat can be provided to the user when acupressure is applied to the protrusion (34).

[0054] According to one embodiment, the heating unit (60) may be composed of a heating pad capable of implementing a steaming effect. The heating pad may include a material that emits far infrared rays or negative ions.

[0055] According to one embodiment, the heating unit (60) may include a surface heating element using carbon fiber or carbon black.

[0056] The main body (30) may be provided with a temperature sensing unit (71) for sensing the user's body temperature. The temperature sensing unit (71) may include a contact or non-contact temperature sensor for sensing the user's body temperature. The temperature sensing unit (71) may be a thermistor, a thermocouple, an infrared sensor, or another suitable temperature sensor. The temperature sensing unit (71) may include one or more temperature sensors configured to detect the user's body temperature at different locations in the receiving unit (31).

[0057] The temperature sensing unit (71) can be electrically connected to the control unit (70). A signal sensed by the temperature sensing unit (71) can be transmitted to the control unit (70). The control unit (70) can control the operation of at least one of the heating unit (60) and the air supply unit (50) based on the sensed temperature of the temperature sensing unit (71).

[0058] The input unit (72) is for receiving various control information from the user. The input unit (72) may be provided in the control box (20). When information is input through the input unit (72), the control unit (70) can control the operation of the foot massager (10) to correspond to the input information. The input unit (72) may include a touch-type input means or a mechanical input means. The input unit (72) may include a number of buttons, switches, etc. for selecting the operation of the foot massager (10). The input unit (72) may include a display unit. The display unit may display an image for a mode selected by the user and display operation information of the foot massager (10).

[0059] The control unit (70) may be composed of a microprocessor, a microcontroller, etc., which has a central processing unit (CPU) that executes a number of computer commands to control the operation of the foot massager (10) or perform various control operations, and may include a memory device such as a random access memory (RAM), a read-only memory (ROM), a flash memory, etc.

[0060] The control unit (70) can heat the receiving unit (31) by operating the heating unit (60) to generate heat, and supply cold air to the receiving unit (31) by operating the air supply unit (50).

[0061] Fig. 4 is a flowchart of a method for controlling a foot massager in a sleep induction mode according to one embodiment. Fig. 5 is a flowchart of a method for controlling a foot massager in a sleep maintenance mode according to one embodiment.

[0062] Referring to FIGS. 4 and 5, the control unit (70) may include a sleep induction mode (73) and a deep sleep maintenance mode (74). When the control unit (70) receives a user's usage signal through the input unit (72), the control unit (70) may sequentially perform the sleep induction mode (73) and the deep sleep maintenance mode (74).

[0063] The sleep induction mode (73) can help the user fall asleep easily, and the deep sleep maintenance mode (74) can help the user maintain deep sleep during sleep.

[0064] Referring to Fig. 4, the sleep induction mode (73) can help the user fall asleep by raising the user's body temperature, maintaining it for a certain period of time, and then lowering it to relieve tension in the user's body and maintain a relaxed state.

[0065] The control unit (70) can control the heating unit (60) to operate at a first set temperature for a first set time in the face-induction mode (73). Here, the first set temperature may be approximately 50 to 60 degrees, and the first set time may be approximately 15 to 30 minutes. At this time, the control unit (70) can perform a thermal massage operation by controlling the pump unit (40) to expand and contract a plurality of air cells (32) while heating through the heating unit (60).

[0066] The control unit (70) can control the operation of the air supply unit (50) to supply cold air to the receiving unit (31) after the first set time has elapsed.

[0067] Through this, the user's core body temperature (inside the skin) can be increased through a thermal massage before going to sleep, and then drowsiness can be induced by lowering the core body temperature using the cold air function.

[0068] The deep sleep maintenance mode (74) can maintain the user's body temperature at a constant level during deep sleep. The deep sleep maintenance mode (74) detects the user's body temperature in real time, and if the user's body temperature deviates from the set temperature, it can provide warm or cold air to the receiving unit (31) to maintain the set temperature.

[0069] Referring to FIG. 5, the control unit (70) determines the user's body temperature in real time based on a detection signal transmitted from the temperature detection unit (71) in the deep sleep maintenance mode (74), and if the user's body temperature deviates from a preset temperature, the control unit (70) can control the operation of either the heating unit (60) or the air supply unit (50).

[0070] For example, the control unit (70) can operate the heating unit (60) to perform a heating function when the user's body temperature is lower than the set temperature, and can operate the air supply unit (50) to perform a cooling function when the user's body temperature is higher than the set temperature.

[0071] Fig. 6 schematically illustrates a cross-section of a foot massager according to one embodiment. Fig. 7 is a control block diagram of a foot massager according to one embodiment. In the following, components having the same functions as the aforementioned components are assigned the same drawing numbers, and detailed descriptions are omitted.

[0072] Referring to FIGS. 6 and 7, a foot massager (10) according to one embodiment of the present disclosure may be configured to omit the heating unit (60) and supply cold or warm air through the air supply unit (50).

[0073] The air supply unit (50) may include a thermoelectric element (51), a fan (52), and a polarity converter (53) for controlling the direction of current flow to the thermoelectric element (51).

[0074] The polarity converter (53) may include a switch, H-bridge circuit, etc. that can change the voltage polarity of the thermoelectric element (51).

[0075] The air supply unit (50) generates cold air or warm air from the thermoelectric element (51) according to the switching operation of the polarity converter (53), and the generated cold air or warm air can be supplied to the air path (36) by the blowing force of the fan (52).

[0076] Specifically, when power is applied to the thermoelectric element (51), one side becomes cold and the other side releases heat due to the Peltier effect. The fan (52) can supply the cold air to the air passage (36) through the hose provided on the cable (11). Conversely, when the polarity of the power applied to the thermoelectric element (51) is changed by switching the polarity converter (53), one side of the thermoelectric element (51) releases heat and the other side becomes cold. Therefore, the fan (52) can supply air heated by the released heat to the air passage (36) through the hose provided on the cable (11).

[0077] Fig. 8 is a flowchart of a method for controlling a foot massager in a sleep induction mode according to one embodiment. Fig. 9 is a flowchart of a method for controlling a foot massager in a sleep maintenance mode according to one embodiment.

[0078] Referring to Fig. 8, the control unit (70) can control the operation of the air supply unit (50) to supply warm air to the receiving unit (31) for a first set time at a first set temperature in the elevation induction mode (75). Then, after the first set time, the control unit (70) can control the polarity converter (53) to change the polarity of the power applied to the thermoelectric element (51), thereby supplying cold air from the air supply unit (50).

[0079] Referring to FIG. 9, the control unit (70) determines the user's body temperature in real time based on a detection signal transmitted from the temperature detection unit (71) in the deep sleep maintenance mode (76), and if the user's body temperature deviates from a preset temperature, the control unit (50) can be controlled to supply warm or cold air by controlling the polarity converter (53).
