The side passage 11c is a passage for opening the accommodation space 11a and is opened and closed by the door 13 . The door 13 is connected to the main body 11 by a hinge 13a and is handled by a user to open and close the side passage 11c.

By forming the side passage 11c in this way, the sterilization unit 40 can be operated in a detachable manner. That is, the sterilization unit 40 can be taken out through the side passage 11c to the outside, or mounted in the main body 11 through the side passage 11c. As much as the sterilization unit 40 can be separated, maintenance of the sterilization unit 40 is easy, and the sterilization unit 40 itself can be replaced as needed.

The upper portion of the body 11 having the above configuration is covered with a sealing cover 17 . When the foot massager 10 is not in use, the sealing cover 17 covers the receiving space 11a to prevent foreign substances from penetrating into the receiving space. The body 11 and the sealing cover 17 may be connected by a wire 17a.

In addition, an upper switch 31 is installed at the upper end of the main body 11 . The upper switch 31 is connected to the control unit 21, and when the sealing cover 17 is put on, it outputs a signal by being pressed by the weight of the sealing cover. The control unit 21 can know that the sealing cover 17 is installed on the upper end of the main body 11 through the upper switch 31 .

The control unit 21, when receiving a signal from the upper switch 31, operates the sterilization unit (40). This control method is already built into the control unit 21 . Even if the user puts only the sealing cover 17 on, the inside of the main body 11 is sterilized.

The operation of the foot massager 10 having the above configuration is made as follows.

First, the main switch 24 is switched to an on state, a desired operation mode is inputted through the input panel 23 , and a foot is put into the accommodation space 11a. When a foot is put in the accommodation space 11a, the foot sensor 33 detects the foot, and transmits the sensed fact to the control unit 21 .

After receiving the signal from the foot detection sensor 33, the control unit 21 operates the massage unit 27 and the sterilization unit 40 after a set time elapses. The set time may be 3 seconds to 5 seconds. The driving method of the massage unit 27 and the sterilization unit 40 follows the input through the input panel 23 .

Through the above process, if the massage and sterilization process is finished, and the massage unit 27 and the sterilization unit 40 are stopped, the sealing cover 17 is put on the body 11 after removing the foot. When the sealing cover 17 is put on, the upper switch 31 is pressed to generate a signal, and the control unit 21 operates the sterilization unit 40 . The accommodation space (11a) is automatically sterilized in a closed state by the sealing cover (17).

5 is a cross-sectional view for explaining the configuration of the foot massager 10 having a plasma sterilization function according to the second embodiment of the present invention, and FIG. 6 is a block diagram for explaining the operation of the massager shown in FIG.

Hereinafter, the same reference numerals as the above reference numerals indicate the same members having the same functions.

The foot massager 10 according to the second embodiment may perform massage and sterilization at the same time or selectively. For example, both massage and sterilization can be performed, and when the user desires, only massage and no sterilization, or only sterilization without massage, can be performed.

The foot massager of the second embodiment further includes an airbag 55 , a pressure regulator 53 , a bottom dead center switch 59 and a switching column 57 , and a built-in switch 51 compared to the first embodiment.

The airbag 55 is a member provided between the sterilization unit 40 and the massage unit 27, and elevates the massage unit 27 through expansion and contraction. When the airbag 55 is inflated, the massage unit 27 itself rises, and when the airbag 55 is contracted, the massage unit 27 descends.

The inflation and deflation of the airbag 55 are performed by the pressure regulator 53 . The pressure regulator 53 is a device that presses air into the airbag 55 or discharges the pressurized air to the outside, and operates by receiving power from the battery 25 . The operation of the pressure regulator 53 is controlled by the control unit 21 .

The bottom dead center switch 59 is a switch mounted on the bottom surface of the massage unit (27). The bottom dead center switch 59 generates a signal when the massage unit 27 descends and meets the switching column 57 at the moment it finally reaches the bottom dead center. The signal is generated in a state in which the massage unit 27 is descended as much as possible. The signal generated by the bottom dead center switch 59 is transmitted to the control unit 21 , and the control unit 21 stops the pressure regulator 53 .

The built-in switch 51 is a switch operated by the user using the toes. For example, the user can operate the switch by lifting the big toe in the direction of the arrow e. When the built-in switch 51 is touched with a toe, a touch signal is transmitted to the control unit 21 . As will be described later, when the built-in switch 51 is touched once, the massage unit 27 and the sterilization unit 40 operate at the same time. In addition, when the built-in switch is continuously touched twice, the massage unit descends to the bottom dead center, and only the sterilization unit 40 operates in that state.

The operation of the foot massager 10 according to the second embodiment having the above configuration is made as follows.

When the user puts his/her foot in the receiving space 11a, the foot detection sensor 33 generates a signal and transmits it to the control unit 21 . The control unit operates the massage unit 27 after a set time, for example, 3 seconds to 5 seconds have elapsed. The output intensity or operation pattern of the massage unit 27 is previously input through the input panel 23 .

If you want to sterilize your feet in this state, lift your toes and touch the built-in switch 51 once. When the built-in switch 51 is touched once, the control unit 21 additionally operates the sterilization unit 40 .

In this way, while performing the massage and sterilization at the same time, if the massage is unnecessary, lift the big toe again and touch the built-in switch 51 twice. When the built-in switch is touched twice, the control unit 21 stops the massage unit 27 and descends to the bottom dead center. The user's feet descend and are sterilized in a state closer to the sterilization unit 40 .

As described above, if only the sterilization of the foot is desired from the beginning, the built-in switch 51 is touched twice as soon as the foot is put into the receiving space 11a. When the built-in switch 51 is touched twice, the control unit 21 lowers the massage unit 27 and then operates the sterilization unit 40 .

As mentioned above, although the present invention has been described in detail through specific embodiments, the present invention is not limited to the above embodiments, and various modifications are possible by those of ordinary skill within the scope of the technical spirit of the present invention.
