The massage device 100 may include an acupressure protrusion main housing 740 . The acupressure projection main housing 740 may include a groove into which the spiral shaft 730 can be inserted. The thread of the spiral shaft 730 may be engaged with the thread of the inner circumferential surface of the groove of the acupressure projection main housing 740 .

Since the screw thread of the spiral shaft 730 and the screw thread of the acupressure projection main housing 740 are engaged, the acupressure projection main housing 740 may move forward or backward with respect to the foot massage unit based on the rotation of the spiral shaft 730. . For example, when the spiral shaft 730 rotates clockwise, the acupressure projection main housing 740 moves forward, and when the spiral shaft 730 rotates counterclockwise, the acupressure projection main housing 740 can move backward. . Conversely, when the spiral shaft 730 rotates clockwise, the acupressure projection main housing 740 moves backward, and when the spiral shaft 730 rotates counterclockwise, the acupressure projection main housing 740 can move forward. When the spiral shaft 730 rotates once, the acupressure projection main housing 740 may move forward or backward by the lead distance. The lead distance may be predetermined by a screw thread.

The massage device 100 may include an airbag 750 . The airbag 750 may be in the form of a bellows. The airbag 750 may be connected to the valve. The valve may be opened or closed based on a signal from the controller 300 . Air may be trapped in the airbag 750 when the valve is closed. When the valve is opened, air may be injected into or discharged from the airbag 750 .

The valve may be connected to the compressor. The compressor may inject or discharge air based on a signal from the controller 300 . The signal of the control unit 300 may include at least one of information related to whether the compressor operates, whether a valve is opened or closed, and an air supply amount per hour of the compressor.

If the valve is opened while the compressor injects air, air may be injected into the airbag 750 .

Also, when the valve is opened in a state in which the compressor does not inject air, air may be discharged from the airbag 750 . Here, the state in which the compressor does not inject air may mean a state in which the compressor sucks air or does not operate. When the compressor does not operate and the valve is opened, the airbag 750 is reduced by at least one of the weight of the acupressure protrusion 760 and the elastic force of the elastic body 770 , and the air inside the airbag 750 may be discharged.

The massage device 100 may include an acupressure protrusion 760 . The acupressure protrusion 760 may be located in the airbag mounting groove 741 of the acupressure protrusion main housing 740 . The acupressure projection 760 may be located on the airbag 750 .

As shown in the left figure of FIG. 10 , when air is injected into the airbag 750 and the airbag 750 is inflated, the acupressure protrusion 760 may rise. When the acupressure protrusion 760 rises, the massage device 100 may provide a massage by applying pressure to the bottom of the user's foot. Pushing the acupressure protrusion 760 upward is a soft airbag 750 , so the acupressure protrusion 760 may not apply excessively large pressure to the user. Therefore, the user can safely receive a foot massage.

Also, the airbag 750 may include an air damper. The air damper may be opened when the pressure inside the air bag 750 is equal to or greater than the critical pressure. That is, when the pressure inside the airbag 750 is equal to or greater than the critical pressure, the air inside the airbag 750 may be discharged through the air damper. Therefore, the acupressure projection 760 may not apply more than a predetermined pressure to the user.

As shown in the right figure of FIG. 10 , when air is discharged from the airbag 750 and the airbag 750 contracts, the acupressure protrusion 760 may descend.

When the acupressure protrusion 760 rises due to the expansion of the airbag 750, the acupressure protrusion 760 may rotate based on the screw thread of the acupressure protrusion 760 and the thread formed in the groove of the mounting groove cover 780. .

For example, referring to FIG. 10 , when the acupressure protrusion 760 rises due to inflation of the airbag 750 , the acupressure protrusion 760 may rotate in a clockwise direction. Also, when the acupressure protrusion 650 descends due to the contraction of the airbag 750 , the acupressure protrusion 760 may rotate counterclockwise. However, the present invention is not limited thereto, and when the acupressure protrusion 760 rises due to the expansion of the airbag 750, the acupressure protrusion 760 may rotate counterclockwise, and the acupressure protrusion 760 may be rotated counterclockwise by the contraction of the airbag 750. When the 650 is descending, the acupressure projection 760 may rotate in a clockwise direction.

The lead distance, which is the distance the acupressure protrusion 760 moves during one rotation of the acupressure protrusion 760 based on the thread 1110 of the acupressure protrusion 760 and the thread formed in the groove of the mounting groove cover 780, is the lead distance of the acupressure protrusion. It may be the length 1130 of the body part. However, the present invention is not limited thereto, and the lead distance may be changed according to the design of the screw. As the lead distance increases, the airbag 750 may raise the acupressure protrusion 760 with less force. In addition, as the lead distance increases, the elastic body 770 may lower the acupressure protrusion 760 with a small force.

As described above, the acupressure protrusion 760 may move back and forth with respect to the massage device 100, or may rise or fall. In addition, the acupressure protrusion 760 may be rotated about the axis of rotation. The controller 300 may control the movement of the acupressure projection 760 . That is, the acupressure protrusion may rise or fall based on the signal of the controller 300 . For example, the control unit 300 may transmit a signal to the valve. The valve may be opened or closed based on a signal from the controller 300 . The controller 300 may transmit a signal to the compressor. The compressor may inject air, suck air, or perform no operation on the basis of a signal from the controller 300 . The controller 300 may control the air supply amount per hour of the compressor. The controller 300 may control the acupressure protrusion 760 to rise rapidly by allowing the compressor to supply a lot of air per hour. The massage device 100 may adjust the intensity of the foot massage by adjusting the rising speed of the acupressure protrusion 760 .

The control unit 300 may transmit a signal to the driving unit 710 . The driving unit 710 may rotate the spiral shaft 730 based on a signal from the control unit 300 . The acupressure projection main housing 740 may move forward or backward based on the rotation of the spiral shaft 730 . The acupressure projection 760 included in the acupressure projection main housing 740 may also move forward or backward together with the acupressure projection main housing 740 . The massage device 100 may adjust the intensity of the foot massage by adjusting the speed of the forward and backward movement of the acupressure protrusion 760 .

12 is a view showing acupressure projections according to an embodiment of the present disclosure.

The lower surface of the acupressure protrusion 760 may include friction reducing protrusions 1210 and 1220 . More specifically, the lower surface of the pedestal 1122 of the acupressure protrusion 760 may include friction reducing protrusions 1210 and 1220. The friction reducing protrusions 1210 and 1220 may be made of a plastic material. In addition, at least a portion of the upper surface of the airbag may be made of a plastic material. The friction reducing protrusions 1210 and 1220 may reduce frictional force between the lower surface of the acupressure protrusion 760 and the upper surface of the airbag 750 . This is because the lower surface of the acupressure protrusion 760 and the upper surface of the airbag 750 are in line contact or point contact rather than in surface contact by the friction reducing protrusions 1210 and 1220 . Also, a lubricant may exist between the friction reducing protrusions 1210 and 1220 and the upper surface of the airbag 750 .

The friction reducing protrusions 1210 and 1220 on the lower surface of the acupressure protrusion 760 may be ring-shaped. The center of the friction reducing protrusions 1210 and 1220 may be on the axis of rotation of the acupressure protrusions. As shown in the left figure of FIG. 12 , there may be one friction reducing protrusion 1210 . However, the present invention is not limited thereto. As shown in the right figure of FIG. 12 , there may be two or more friction reducing protrusions 1220 .

The shape of the friction reducing protrusion is not limited to a ring shape. The friction reducing protrusion may have a conical shape. The lower surface of the acupressure protrusion 760 may include a plurality of friction reducing protrusions.

13 is a view showing acupressure projections according to an embodiment of the present disclosure.

The upper side of the acupressure protrusion 760 may include at least one sub-protrusion 1310 , 1320 , 1330 extending in the longitudinal direction of the acupressure protrusion 760 . Specifically, the head 1123 of the acupressure protrusion 760 may include sub-protrusions 1310 , 1320 , 1330 . The longitudinal direction of the acupressure protrusion 760 may refer to the longitudinal direction of the body 1121 of the acupressure protrusion 760 of FIG. 11 .

Referring to the left figure of FIG. 13 , the acupressure protrusion 760 may include one sub-protrusion 1310 . One sub-protrusion 1310 may be biased toward one side of the head 1123 . That is, the center of the sub-projection 1310 may not be on the axis of rotation of the acupressure projection 760 . When the acupressure protrusion 760 rotates, the sub-protrusion 1310 may also rotate about the axis of rotation of the acupressure protrusion 760 . According to the present disclosure, the massage device 100 may provide a user with a massage similar to that of a person massaging a foot while turning a thumb.

The upper side of the acupressure protrusion 760 may include a rough surface to remove dead skin cells from the soles of the feet. That is, at least a portion of the head 1123 of the acupressure projection 760 may be a rough surface. In addition, at least a portion of the sub-projection 1310, 1320, 1330 of the acupressure projection 760 may be a rough surface. The rough surface of at least a portion of the head 1123 or the sub-protrusions 1310 , 1320 , and 1330 may remove dead skin cells from the sole of the user's foot.

In addition, under the acupressure projection main housing 740 of the massage device 100 may include a vacuum suction port for collecting the user's dead skin cells. The control unit 300 may control the vacuum suction port to operate only when the acupressure protrusion 760 operates. Alternatively, the control unit 300 may control the vacuum suction port to operate while the user uses the foot massage unit 500 . Alternatively, the controller 300 may control the vacuum suction port to operate while the massage device 100 is turned on. Alternatively, the controller 300 may control the vacuum suction port to operate based on a user's input. The control unit 300 allows the vacuum suction port to operate only under specific conditions, thereby reducing energy consumption of the massage device 100 and suppressing unnecessary noise that may be generated while providing a massage so that the user can enjoy the massage in a comfortable atmosphere. .

The foot massage unit 500 may include an instep airbag. The feet airbag may be an airbag located on the instep of the user's feet. The instep airbag may support the user's instep. When the acupressure protrusion 760 is raised, if the user's feet are lifted, the acupressure protrusions 760 may not apply any pressure to the user's feet. The instep airbag supports the user's instep, thereby preventing the user's foot from being lifted when the acupressure protrusion 760 rises.

When the acupressure protrusion 760 rises, the controller 300 may control to inject air into the instep airbag. In addition, when the acupressure protrusion 760 descends, the control unit 300 may control the air to be discharged from the instep airbag. Also, the control unit 300 may inflate the instep airbag regardless of whether the acupressure protrusion 760 rises or descends. When the user puts a foot in the foot massage unit 500 , the control unit 300 may inflate the instep airbag. Also, the controller 300 may maintain the instep airbag to be inflated while the massage device 100 is operating.

The massage device 100 may include a blower. More specifically, the acupressure projection main housing 740 may further include a blower. The blower may flow air from the user's foot to the sole of the foot based on a signal from the controller 300 . However, the present invention is not limited thereto, and the blower may flow air from the sole of the user's sole to the instep of the foot based on the signal of the control unit 300 . When the massage device 100 provides acupressure to the user, the user may be nervous and sweat. In this case, the foot massage unit 500 may become wet. Moisture may reduce the lifespan of various devices of the massage device 100 . In addition, when the foot massage unit 500 is wet, there is a possibility that mold may grow, which may be harmful to the user.

The control unit 300 may control the blower to turn on while the foot massage unit 500 operates. In addition, the control unit 300 may control the blower to turn on while the massage device 100 is operating. Therefore, the user can receive a foot massage in a non-humid state.

In addition, the control unit 300 may operate the blower for a predetermined time even after the operation of the massage device 100 stops. Therefore, the blower can dry the sweat from previous users. The blower can also cool the previous user's body temperature. The blower can also remove body odors from previous users. The next user can receive a foot massage in a dry state.

In addition, the head 1123 of the acupressure protrusion 760 may include a micro-jet hole. In addition, the upper end of the sub-projection of the acupressure projection 760 may include a micro-jet hole. Acupressure projection 760 may be directly connected to the compressor through the tube.

However, the present invention is not limited thereto, and the acupressure projection 760 may be indirectly connected to the compressor. For example, the acupressure protrusion 760 may be connected to the airbag 750 through a tube. Therefore, when the compressor supplies air to the airbag 750 , air is also supplied to the acupressure protrusion 760 so that the high-pressure air can be discharged toward the user's feet through the micro-injection hole. Conversely, when the compressor discharges air from the airbag 750, a vacuum is formed between the fine injection hole of the acupressure protrusion 760 and the user's firing, so that the micromassage device 100 can provide buoyancy. Also, when the valve of the airbag is opened while the compressor is not operated, the airbag 750 may be contracted by the elastic body 770 . At this time, the high-pressure air is discharged to the user from the micro-injection port to provide a micro-massage to the user.

The compressor may supply air to the fine nozzles, or may suck in air from the fine nozzles. The control unit 300 may transmit a control signal to the compressor to control the fine injection hole to discharge high-pressure air to the sole of the user's sole. The control unit 300 may transmit a control signal to the compressor to control the vacuum to be generated between the fine injection hole and the sole of the user's foot. The fine nozzle may have a diameter of 1 mm or less. The high-pressure air discharged from the fine nozzle may provide a massage to the user. Also, the vacuum between the micro nozzle and the user's sole can provide the user with micro-buoyancy.

If the acupressure protrusion 760 applies pressure to a wide range of the user's sole, the air of the micro-spray can apply pressure to the fine range of the user's sole. There are various acupuncture points on the soles of the feet, and the micro nozzle can spray air to the acupoints. In addition, the fine nozzle can create a vacuum in the acupuncture point to provide buoyancy.

More specifically, the controller 300 may acquire an image of the user's sole of the foot by using an image sensor. The image sensor may use an image sensor of a copier or scanner. The controller 300 may determine the user's sole region and the non-sole region from the image of the user's sole.

The controller 300 may compare the image of the user's sole with the standard acupoint image. The standard acupoint image may include a pre-photographed image of the sole of the foot and location information of the acupoint. The controller 300 may control the acupressure protrusion 760 to reach the position of the acupressure point included in the standard acupoint image by moving the acupressure protrusion 760 by a predetermined distance from the reference position.

The controller 300 may enlarge, reduce, or rotate the standard acupoint image to match the image of the user's sole of the foot. The controller 300 may acquire enlargement information, reduction information, and rotation information for the standard acupoint image. The enlarged information and the reduced information may mean a magnification for matching the standard acupoint image with the image of the user's sole. The magnification information may include magnification information on the x-axis and magnification information on the y-axis. Also, the reduction information may include reduction information on the x-axis and reduction information on the y-axis. The rotation information may be information related to a rotation angle for matching the standard acupoint image with the image of the user's sole.

The controller 300 may move the acupressure projection 760 based on at least one of the standard acupoint image, enlarged information, reduced information, and rotation information. More specifically, the controller 300 may move the acupressure projection 760 from the reference position to the position of the acupoint based on the position information of the acupoint included in the standard acupoint image. The controller 300 may further move the acupressure protrusion 760 based on the magnification information to control the acupressure protrusion 760 to be positioned at the acupoint of the user's sole. The controller 300 may control the acupressure protrusion 760 to be positioned at the acupoint of the user's sole by less moving the acupressure protrusion 760 based on the reduction information. The controller 300 may acquire an x-coordinate or a y-coordinate to which the acupressure protrusion 760 should additionally move based on the rotation information. The control unit 300 may control the acupressure protrusion 760 to move the acupressure protrusion 760 based on the x-coordinate or y-coordinate to be additionally moved.

The controller 300 may control the acupressure protrusion 760 to provide acupressure to the acupressure points of the user's feet.

The foot massage unit 500 may further include a heating wire. The foot massage unit 500 may help the user's blood circulation by warming the user's feet.
