The low electrode point group 12111, the middle electrode point group 12112, and the water overflow prevention electrode point group 12113 correspond to three water level heights of the waterproof inner container layer 121, respectively.

[0073] More specifically, the low electrode point group 12111, the middle electrode point group 12112, and the water overflow prevention electrode point group 12113 each include a plurality of positive and negative electrode points. The positive and negative electrode points are adjacent to and correspond to the three water level heights of the waterproof inner container layer 121. When the water level of the waterproof inner container layer 121 reaches the corresponding electrode point group, the water of the waterproof inner container layer 121 will act like a wire to connect the positive and negative electrode points. By measuring the resistance change of the positive and negative electrode points at the water level, the water level of the waterproof inner container layer 121 can be determined. It should be understood that the number and arrangement of the electrode point groups 1211 and the positive and negative electrode points can be adjusted according to actual needs.

At the same time, the boot body structure 11 is provided with a gas supply structure 13 for controlling the inflation degree of the air bag groups 1231, and the boot body structure 11 is provided with a power supply structure 15 for controlling the operation of the heating sheet. By arranging the air bag groups 1231 in this way, the foot bath boots 1 not only can massage the feet of the user, but also can massage the legs of the user, and the massage experience effect is better. It should be noted that the air bag groups 1231 can be air bags in a region of the air bag layer 123, or can be single air bags in the air bag layer 123.

[0076] With reference to Figure 16 The gas supply structure 13 includes a gas pump 131 arranged in the cavity between the instep structural member 112 and the sole structural member 111, a plurality of gas valves 132, and a plurality of air pressure sensors. The gas pump 131 is connected with the plurality of gas valves 132, the plurality of gas valves 132 are connected with and correspond to the plurality of air pressure sensors, and the plurality of air pressure sensors are connected with and correspond to the plurality of air bag groups 1231. The gas pump 131 is used to provide gas for the air bags, the gas valves 132 are used to control the on-off and direction of the gas path, and the air pressure sensors are used to detect the air pressure value of the air bag groups 1231.

[0077] The power supply structure 15 includes a circuit board 151 arranged in the cavity between the instep structural member 112 and the sole structural member 111, and a battery 152 electrically connected with the circuit board 151. The battery 152 is used to provide power for each component of the foot bath boots 1, and the battery 152 is connected with a charging interface 153 used to cooperate with a power supply interface of a base station. When the foot bath boots 1 are placed in the matching base station 2, the base station 2 will charge the foot bath boots 1. By arranging the battery 152 and using the battery 152 to supply power to the heating sheet layer 122, the use safety of the foot bath boots 1 can be effectively improved.

[0078] With reference to Figure 16 and Figure 17The boot body structure 11 is further provided with a detection structure 14. Specifically, the detection structure 14 comprises a touch sensor 141 electrically connected with the power supply structure 15 and a strain gauge 142. The touch sensor 141 is arranged in a cavity between the instep structure 112 and the sole structure 111, and has a retractable free end 1411 which penetrates the sole structure 111 and faces away from one end of the foot bath boot 1. When the user lifts the foot, the free end 1411 will extend from the sole structure 111, and at this time it can be known that the user is in a walking state. The strain gauge 142 is arranged on one side of the instep structure 112 close to the inner container structure 12. The strain gauge 142 is a resistance strain element. When the user stands, the strain gauge 142 will be deformed, and the resistance of the strain gauge 142 will change. When a large change in the resistance of the strain gauge 142 is detected, it can be known that the user is in a standing state.

[0079] The use process of the foot bath equipment is as follows: the user takes out the water tank 22 to get water, and after getting the water, the user puts the water tank 22 into the matching base station 2. The instant heating structure 23 of the matching base station 2 draws water in the water tank 22 to heat and then injects the water into the foot bath boot 1. The user uses the foot bath boot 1 to perform foot bath massage. After completing the foot bath massage, the user pours out the water in the foot bath boot 1 and puts it back into the matching base station 2. The matching base station 2 sterilizes, cleans and dries the foot bath boot 1.

[0080] Embodiment two

[0081] Reference Figure 18 In a second aspect, the application provides a control method of the foot bath equipment, comprising the following steps:

[0082] S1: The matching base station 2 injects a preset amount of water into the foot bath boot 1, and then judges whether the user is in a walking state;

[0083] Specifically, the specific steps of S1 are as follows: the matching base station 2 starts to inject hot water into the foot bath boot 1, and after a preset time, the state of the free end 1411 of the touch sensor 141 and the strain gauge 142 is acquired. If the free end 1411 of any foot bath boot 1 is in an extended state, and at the same time the resistance of the strain gauge 142 changes greatly, it is judged that the user is in a walking state. If the free end 1411 is not extended, it is judged that the user is not in a walking state.

[0084] S2: If the user is in a walking state, the foot bath boot 1 is controlled to clamp the leg of the user; if the user is not in a walking state, the foot bath boot 1 is controlled to massage the foot and leg of the user;

[0085] Specifically, if the user is in a walking state, the air supply structure 13 drives a plurality of air bag groups 1231 at the top of the air bag layer 123 to expand. In this embodiment, the expanded air bag groups 1231 are the air bag groups 1231 at the top of the air bag layer 123, which will wrap the user's legs tightly, so that the foot bath boots 1 are fixed on the user's legs. At the same time, the remaining air bag groups 1231 contract, so that the water level in the foot bath boots 1 drops, and the water in the foot bath boots 1 will not spill out because the user is walking;

[0086] If the user is in a stopped state, the air supply structure 13 drives a plurality of air bag groups 1231 in the air bag layer 123 to uniformly expand to a first preset degree, and then the air supply structure 13 drives a plurality of air bag groups 1231 in the air bag layer 123 to intermittently expand and contract on the basis of the first preset degree, thereby massaging the user's feet and legs.

[0087] S3: Obtain the water level in the foot bath boots 1, and divide the water level into three situations: less, appropriate, and excessive;

[0088] Specifically, when the water level of the waterproof inner liner layer 121 reaches the corresponding electrode point group, the water in the waterproof inner liner layer 121 will act like a wire to connect the positive and negative electrode points, and by measuring the resistance point change of the positive and negative electrode points of this water level, the water level of the waterproof inner liner layer 121 can be obtained:

[0089] When the low electrode point group 12111 is triggered, and the middle electrode point group 12112 and the anti-overflow electrode point group 12113 are not triggered, the water level is in the less situation; when the low electrode point group 12111 and the middle electrode point group 12112 are triggered, and the anti-overflow electrode point group 12113 is not triggered, the water level is in the appropriate situation; when the low electrode point group 12111, the middle electrode point group 12112, and the anti-overflow electrode point group 12113 are triggered, the water level is in the excessive situation.

[0090] S4: Adjust the subsequent water injection amount according to the water level in S3;

[0091] Specifically, during the massage, when the air bag groups 1231 are in a fully inflated state, i.e., the pressure of the air bag groups 1231 is about 30 kpa, the water level of the foot bath boots 1 is in the appropriate water level situation where the middle electrode point group 12112 is triggered and the anti-overflow electrode point group 12113 is not triggered, which is the best state for the foot bath boots 1 to work, but since the volume of the user's feet and legs is unknown, in order to obtain the optimal water injection amount, the specific steps of S4 are as follows:

[0092] S4.1: Obtain the preset water amount X injected by the matching base station 2 into the foot bath boots 1 in S1, and then the air bag groups 1231 are fully inflated and the water level is obtained;

[0093] When the water level is more, the air pressure P1 at which the median electrode point is triggered is recorded, and the data (P1, X) is obtained, and the next water injection amount is reduced by Y, i.e., the next water injection amount is X2 = X-Y;

[0094] When the water amount is appropriate, the subsequent water injection amount is kept stable and unchanged;

[0095] When the water amount is less, the next water injection amount is increased by Y, i.e., the next water injection amount is X3 = X+2Y.

[0096] S4.2: After adjusting the water injection amount according to S5.1, the current water injection amount X2 and the water level condition are obtained,

[0097] When the water level is more, the air pressure P2 at which the median electrode point is triggered is recorded, and the data (P2, X2) is obtained, and a straight line can be obtained from the data (P1, X) and (P2, X2) of S5.1, and the water amount X3 when the pressure is 30 kPa can be calculated, which is used as the next water injection amount;

[0098] When the water level is appropriate, the water amount X2 at this time is recorded as the subsequent water injection amount and kept unchanged.

[0099] When the water amount is less, the next water injection amount is increased by Y, i.e., the next water injection amount is X3 = X+2Y.

[0100] S4.3: After adjusting the water injection amount according to S5.2, the current water injection amount X3 and the water level condition are obtained,

[0101] When the water level is more, the air pressure P3 at which the median electrode point is triggered is recorded, and the data (P3, X3) is obtained, and a curve can be obtained from the data (P1, X) of S5.1 and the data (P2, X2) and (P3, X3) of S5.2, and the water amount X4 when the pressure is 30 kPa is calculated, which is used as the next water injection amount;

[0102] When the water amount is appropriate, the water amount X3 at this time is recorded as the subsequent water injection amount and kept unchanged;

[0103] When the water amount is less, the next water injection amount is increased by Y, i.e., the next water injection amount is X4 = X+3Y.

[0104] S4.4: The above steps are repeated until the foot soaking boot 1 reaches the best working state.
