The medicated bath method has the effects of cold bath and hot bath, and can make the medicine dissolved in water absorbed through skin orifice to act on human body.
Chinese patent No. CN203400072U discloses an external heating foot bath, including dress water container (1) and base (2), dress water container (1) sets up with base (2) components of a whole that can function independently, base (2) include supporting seat (12) and heater tray (9), heater tray (9) are located the inside below of base, dress water container (1) includes metal bottom (3) and container upper portion (4), inlay in container base (6) metal bottom (3) and container upper portion (4), container base (6) upper portion includes support convex part (7), set up running-board (5) above support convex part (7), form cavity (16) between metal bottom (3) and heater tray (9), external source splendid attire heater in cavity (16). Because the utility model discloses itself does not take heating appliance, low in production cost all can use simple structure, operation safety when components of a whole that can function independently or disjunctor. The water through external source heater in to adorning the water container in the scheme of above-mentioned patent heats, has realized water and electricity separation, has ensured power consumption safety, but if the aquatic products production in the water container flows still need install power consumption parts such as water pump additional, this can cause the structure of adorning water container part still comparatively complicated, if the water container is that the material still makes comparatively easily, if the water container need choose for use the better vat of heat preservation effect, then there is great trouble with power consumption parts such as installation water pump.

Compared with the prior art, the invention has the beneficial effects that: according to the invention, the heating assembly with the heating disc is placed in the barrel body and is matched with the induction cooker below the barrel body, so that water in the barrel body is heated; meanwhile, the water spray pipe is arranged on the heating assembly, when water in the heating assembly is heated to be boiled, the water vapor pushes hot water in the heating assembly to be sprayed out from the water spray pipe, and water flow sprayed out from the water spray pipe generates a massage effect on the soles; after the water level in the heating element descends to the lower limit, the float makes side gas inlet and heating element inside switch on along with the water level descends, make the vapor in the heating element discharge from last gas outlet, atmospheric pressure in the heating element descends simultaneously, make the heating plate upwards float under water pressure effect and throw off with the sealing washer, water in the staving is poured into in the heating group price from the heating plate periphery, thus, can realize that the spray pipe intermittent type nature sprays water, can play the sole effect of massage on the one hand, on the other hand can also make the staving in (outside the heating element) everywhere temperature even, just so need not additionally to install the power consumption part of a class of water pump again in the staving.
Furthermore, the temporary fixation between the lower end of the floater and the lower shell is realized through magnetic force, so that the floater cannot rise along with the water level in a positive proportion in the process of rising the water level in the heating assembly, and only when the water level rises to the extent that the buoyancy of the floater is offset with the magnetic force, the floater rises upwards, and the side air inlet enters the exhaust pipe again to be in a closed state.
In addition, the output power of the induction cooker is controlled to change the air pressure in the heating assembly, so that the position of the inner sliding pipe relative to the water spraying pipe is changed, the strip-shaped holes are aligned with the water spraying ports at different positions, and hot water is sprayed out from different water spraying ports; the fixed same position of sole of impact of the higher temperature water of avoiding following the water jet spun like this causes the scald, and follow different water jets blowout hot water circularly, play the effect of a disturbance for the temperature is comparatively even everywhere in the staving.
Moreover, through setting up the sprinkler bead to set up the suction tube in sprinkler bead side, make the rivers of following sprinkler bead upper end spun produce great disturbance in the staving, the comfort level of foot when having improved the dipping.
In addition, the handle pipe can be used as a handle for lifting the heating assembly, on one hand, the exhaust holes uniformly formed in the handle pipe are inclined to uniformly exhaust water vapor, and the water vapor is sprayed towards the inner wall of the barrel body, so that a user is prevented from being scalded. The exhaust pipe is used for installing the exhaust valve pipe on one hand, and is used for connecting the handle pipe on the other hand, and the dual-purpose effect of one object is achieved.
The heating plate is used for heating water in the heating assembly (the lower end of the heating plate is abutted to the bottom surface of the barrel body, and the contact area of the lower end of the heating plate and the water in the barrel body is small, so most of heat is absorbed by the water in the heating assembly), and on the one hand, the heating plate plays a role of a one-way valve, and when the heating assembly enters water, the heating plate is upwards separated from the sealing ring, so that the water in the barrel enters the heating assembly through the water inlet channel; after the water heater is used, the heating plate is jacked upwards, so that water in the heating assembly can be drained conveniently.
