The foot bath device with the novel control device comprises a main machine as shown in figure 1, wherein a tub body 1 is arranged inside the main machine, a foot bath cavity is formed in the tub body 1, the main machine comprises a massage disc 11, hemispherical bulges are formed on the upper portion of the massage disc 11, the massage disc 11 is driven to rotate by a motor in the main machine, the main machine further comprises an electric heater (the electric heater is not shown in each figure) for heating water in the tub body 11, and a temperature sensor for detecting water temperature is further arranged in the main machine. When the foot bath is needed, water is poured into the foot bath cavity of the barrel body 1, feet of a person are placed into the foot bath cavity to be soaked, feet can be placed on the massage disc 11 to be massaged, and water is discharged through the water outlet at the bottom of the barrel body 1 after the foot is soaked. The above description is prior art of a foot bath and is not the focus of the present invention and therefore will not be described in detail.

As shown in fig. 1, the host of the present invention is provided with a control device 3, as shown in fig. 1 to 8, the control device 3 includes a knob 31, a transmission mechanism 32, an encoder 35 and a key 36, the knob 31 is connected to the encoder 35 through the transmission mechanism 32, the knob 31 can trigger the key 36 through axial movement, in other words, the knob 31 can rotate through proper limit to the knob 31, and can also move along the axis of the knob 31 itself for a distance sufficient to trigger the key 36, and the control device includes a control system, and the control system is electrically connected to the encoder 35 and the key 36. Encoder 35 is prior art's product, the inside grating dish that is equipped with of encoder 35, be formed with the slot hole of circumferential arrangement on the grating dish, encoder 35's input and grating dish coaxial axle fixed connection, inside emitting diode and the receiver of being equipped with of encoder 35, emitting diode and receiver set up the both sides at the grating dish respectively, the light of emitting diode transmission can see through the slot hole on the grating dish and pass through the receiver again and receive, when the grating dish rotates, the receiver just can obtain optical signal, rethread photoelectric conversion is pulse electrical signal, from the function of speaking, encoder 35 can convert the rotation angle and the direction of encoder 35's input into digital signal output. The key 36 is an electrical element in the prior art, and the key 36 may be a micro-motion key (also called "tact switch") on the market, in which a reset reed is provided. The transmission mechanism 32 may be a synchronous belt drive or a gear drive. The control system controls and is connected with a motor and an electric heater which drive the massage disc 11, and the temperature sensor is electrically connected with the control system.

The working principle of the embodiment is as follows: the knob 31 is rotated by hands, the knob 31 drives the input end of the encoder 35 to rotate, the encoder 35 converts the rotation angle and the direction of the knob 31 into digital signals, and the control system controls the motor for driving the massage disc 11 by using the digital signals, so that the rotation speed of the massage disc 11 can be adjusted, for example, when the knob 31 is rotated clockwise, the rotation speed of the massage disc 11 can be controlled to be increased, and when the knob 31 is rotated anticlockwise, the rotation speed of the massage disc 11 can be controlled to be decreased; when the knob 31 is pressed, the button 36 is activated by the knob 31, and the knob 31 can be reset by the button 36. As shown in fig. 3 and 7, the number of the keys 36 may be two, two keys 36 are connected in parallel, and the two keys 36 are symmetrically arranged on the axis of the knob 31, which is beneficial to balance the force applied to the knob 31. The control system obtains the signal of the key 36, the control system can switch the control function of the knob 31, for example, the control system switches to water temperature control after pressing the knob 31, the control system monitors the water temperature in the barrel 1 through the temperature sensor, when the water temperature rises to the set upper limit value of the control system, the control system turns off the electric heater, and when the water temperature drops to the set lower limit value of the control system, the control system controls the electric heater to be turned back on, for example, when the set upper limit value of the water temperature is 50 ℃, the lower limit value of the water temperature can be set to 47 ℃, thus the water temperature can be stabilized in an interval, the knob 31 can increase the set upper limit value and the lower limit value of the temperature of the control system in a water temperature control mode, for example, when the knob 31 is rotated clockwise, thus the electric heater can heat the water to a higher temperature, and when the knob; the main body can be turned off by pressing the knob 31 again, and in addition, the functions of other prior art foot baths can be switched to by pressing the knob 31.
