The anode plate 91 is connected to the positive electrode of the high-voltage direct current power supply, and the cathode plate 92 is connected to the negative electrode of the high-voltage direct current power supply; the air pump 7 The air outlet end of the cavity 105 communicates with the cavity 105, and the side of the lower part of the cavity 105 is provided with an air hole 106 communicating with the inside of the housing 1.
[0024] Preferably, a recessed hole 303 is provided on the circumference of one end of the pedal bar 3, and the elastic component 35 includes a compression spring 351 and a steel ball 352, and the compression spring 351 is arranged in a counterbore 801 inside the gear 8. The steel ball 352 is matched with the concave hole 303.
[0025] Preferably, the U-shaped bracket 6 is provided with a bracket flow channel 601 inside, and the U-shaped bracket 6 is evenly provided with liquid outlet holes 602 for supplying cleaning liquid to the cleaning bar 61 along the axis direction of the footrest bar. The liquid outlet hole 602 communicates with the holder flow channel 601, and one side of the U-shaped holder 6 is connected to the liquid container 12 through the holder branch pipe 62 in a pipeline. The cleaning liquid is uniformly discharged from the liquid outlet 602 to the cleaning strip 61 after passing through the liquid container 12, the pipe, the support branch pipe 62, and the support flow channel 601 to clean the outer circumference of the footrest 3.
[0026] Preferably, one end of the footrest bar 3 is provided with a matching rotary joint 33 (to realize the conversion between pipe rotation and non-rotation connection), and the rotary joint 33 is connected to the air collecting pipe 34 through a hose. 34 is used to collect multiple gases from the inlet 302.
[0027] Preferably, a temperature control switch 24 is electrically connected to the loop of the heating wire 23 (the model may be KSD301). When the temperature of the heating device 2 reaches the set temperature, the temperature control switch 24 cuts off the power supply. When the temperature of the heating device 2 is lower than the set temperature, the temperature control switch 24 reconnects to the power supply and returns to a normal working state.
[0028] Preferably, a fuse 25 is electrically connected to the loop of the heating wire 23. It prevents that when the temperature control switch 24 on the heating device 2 is damaged and the power supply is not disconnected in time, after the fuse 25 is blown, the power supply is disconnected to play a protective role.
[0029] Preferably, a gear switch 4 (which is convenient for the user to set the temperature required for heating) and a power connection wire 5 are provided on the outside of the housing 1 electrically connected to the heating device 2. easy to use.
[0030] Preferably, a protective net 26 is provided on the top and bottom of the heating device 2. Prevent foreign matter from falling on the heating wire 23 and play a protective role.
[0031] Preferably, the passage formed by the anode plate 91 and the cathode plate 92 and the cavity 105 for gas passage is arranged in an S shape. The formation of gas flow is increased, and the treatment effect is better.
[0032] In specific use, when heating, the heating device 2 is turned on to start heating, and the user's foot is placed on the footrest 3 to warm up, and the odor from the user's foot passes through the air inlet 301, air inlet 302, and pipeline After the deodorizing treatment is performed by the suction pump 7, the cavity 105, and the plasma deodorizing device 9, it is discharged from the vent 106 on the side of the lower part of the cavity 105 into the heater to avoid the overflow of peculiar smell, improve the user experience effect and reduce the temperature At the same time, when the user steps on the pedal bar 3, the U-shaped bracket 6 moves down in the slot 104, the return spring 13 is compressed, and the gear 8 matches the rack 14, but due to foot friction The effect of force makes the pedal strip 3 not rotate, and the cleaning fluid reaches the cleaning strip 61 after passing through the liquid container 12 and the pipe. When the user leaves the pedal strip 3 when the user is not using it, the action of the return spring 13 When the U-shaped bracket 6 moves upward, the gear 8 and the rack 14 rotate together, and the gear 8 drives the pedal bar 3 to rotate at a certain angle (preferably 180 degrees) through the elastic component 35. At this time, the cleaning bar 61 is opposite to the pedal bar 3 Clean, sterilize, and disinfect the place just used to ensure that the outer surface of the footrest 3 is clean and does not affect the next use.
