If steam fumigation can be used to simulate a steam fumigation mode, the above total amount can be solved.

For example, patent application No. 201610866281.8 discloses a foot bath with steam fumigation function, which comprises a water storage tank assembly, a steam boiler assembly and a steam cooling assembly; the steam boiler assembly is arranged adjacent to the water storage tank assembly, self-balancing water supply is realized by the water storage tank assembly and the water storage tank assembly, and the water storage tank assembly is required to be lower than the steam cooling assembly for the self-balancing water supply; the steam cooling assembly is arranged above the steam boiler assembly, and sucks steam and external cold air simultaneously through the fan, cools the steam and sends the steam to the side face. The steam boiler component comprises a boiler body, a PTC heating block, a temperature controller, a furnace cover and the like; water enters from the lower part of the boiler body, and steam is discharged from the furnace cover, so that the structure is simple and convenient.

However, in such equipment, because the steam is required to be discharged quickly, the space of the steam generating chamber is designed rarely, so that water is required to be supplemented continuously, a large load is caused on the liquid level sensor and the electromagnetic valve, and meanwhile, the liquid level sensor is also influenced by water scaling and the like, so that the reaction is insensitive, the misoperation is caused frequently, and the like.

How to optimize the design, make the scheme that supplies water energy self-balancing, become the utility model discloses the object of research.

The invention content is as follows:

the utility model aims at designing a steam foot bath basin self-balancing water supply device which supplies water to a steam assembly through a high-level drop and automatically replenishes water through air pressure balance.

The utility model discloses technical scheme realizes like this: a self-balancing water supply device for a steam foot bath basin comprises a water tank, a heating bin, a bin cover and a PTC heater; the bin cover is arranged at the top of the heating bin and is guided out by a steam channel arranged on the bin cover; the method is characterized in that: the heating chamber is divided into a heating chamber and a water storage chamber which are arranged side by side and the upper part and the lower part of which are communicated, and the PTC heater is arranged on the wall of the heating chamber, which is far away from the water storage chamber, and is arranged vertically; the water tank is arranged in the space above the top of the heating bin and is of a sealing structure, the water tank is introduced into the water storage cavity through a pipeline at the bottom, and the height of a water outlet in the water storage cavity is set in the height range from one third of the height of the PTC heater to the same height.

The diameter of the water outlet in the water storage cavity is not less than 7mm, and the diameter of the communicated pipeline is not less than 7 mm.

The wall of the water storage cavity of the heating bin and the wall of the cavity divided by the heating cavity have thickening structures or hollow structures with heat insulation functions.

The utility model designs a scheme of automatic water supply by a sealed water tank and air pressure balance by utilizing the principle of air pressure balance, meets the requirement of real-time water supply of the heating bin, can realize the accurate control of the water surface, does not need additional sensors and valves, and can reduce various faults caused by water quality; and the heating chamber is divided into a heating chamber and a water storage chamber, so that the problems of high steam generation speed and no influence on the stability of the liquid level of the water storage chamber due to boiling are solved, and the heat loss can be reduced by the divided chamber wall heat insulation design.

The specific implementation mode is as follows:

referring to fig. 1, 2 and 3, the self-balancing water supply device for the steam foot bath comprises a water tank 1, a heating bin 2, a bin cover 3 and a PTC heater 4.

The heating chamber 2 is divided into a heating cavity 21 and a water storage cavity 22 which are in a side-by-side structure, the upper part and the lower part are communicated, namely the lower part supplies water, and the upper part keeps air pressure balance; the upper part of the heating bin 2 is communicated with a steam channel 31 on the bin cover 3, or forms a steam channel together with the bin cover 3; the wall 23 of the water storage cavity 22 and the heating cavity 21 has a thickened structure or a hollow structure 231 as shown in the figure, which has a heat insulation function, so that heat loss is reduced as much as possible, and the water replenishing process and steam generation interfere with each other.

The bin cover 3 is arranged at the top of the heating bin 2 and is guided out by a steam channel 31 arranged on the bin cover 3 for foot bath, and a fan can be arranged on the bin cover 3 for providing power to pump steam.

And the PTC heater 4 is arranged on the wall of the heating cavity 21 far away from the water storage cavity 22 and is vertically arranged so as to rapidly heat and generate hot steam. The cold water is heated by the bottom of the PTC heater 4, boiled in the middle and heated by the upper steam.

The water tank 1 is arranged in the space above the top of the heating chamber 2, is of a sealing structure, is introduced into the water storage cavity 22 through the pipeline 11 at the bottom, and is positioned at the height of the water outlet 221 in the water storage cavity, and is arranged in the height range from one third of the height of the PTC heater 4 to the same height, namely the height of the liquid level submerging the water outlet 221 is in the height range from one third of the height of the PTC heater 4 to the same height. Once the water outlet 221 is submerged, the water supply to the water storage cavity 22 is stopped due to the balance of the air pressure inside and outside the sealed water tank 1, the liquid level falls to expose the water outlet 221 along with the evaporation of the water in the heating cavity 21, the air enters the water tank 1 and is replenished again, and the process is repeated.

In order to reduce the water adsorption of the water outlet 221 and the pipeline 11, the diameter of the water outlet 221 and the pipeline 11 is not less than 7 mm.
