Detailed Description

Referring to fig. 1-4, the housing (body portion) 10 of such a boiler may take the form of a conventional steamer or other suitable shape, the peripheral surface (side) of the housing may be substantially cylindrical, the bottom (bottom of the housing, or pan bottom) 12 may be a flat bottom (see fig. 3), or a downwardly convex bottom, the convex bottom may take the form of a sphere (crown) or a truncated cone, or the outer portion of the bottom may be truncated cone, the middle portion may be flat (horizontal) circular, etc. (see fig. 1 and 2). When the bottom of the pan is a convex bottom, a plurality of supporting feet 16 can be arranged according to actual needs, and the number of the supporting feet can be three or more than three, and the supporting feet can be distributed on a circumference, for example, below the side wall of the shell at equal angular distances. If necessary, a support (or pot holder) can also be provided for stable support of the housing. According to actual needs, a water outlet (or called water outlet pipe) 14 can be arranged on the bottom or the side wall near the bottom of the shell for outputting the liquid medicine, a valve or a tap is arranged on the water outlet, and the valve is opened to lead out the liquid medicine when necessary. Since the inner casing is provided in the casing, the liquid medicine above the inner casing bottom 41 is filtered through the bottom of the inner casing (the casing bottom), so that the residues or other impurities cannot pass through the filtering holes and reach below the casing bottom. The housing (and other parts) may be made of stainless steel or metal/alloy materials thereof suitable for use in medicine to facilitate processing and use. If appropriate, materials such as ceramics may be used.

The inner casing has two main functions, namely, filtering/blocking the residue (or called impurities, generally refers to solid matters in the casing, including added medicinal materials or other matters) along with the medicinal liquid (or called water, generally refers to liquid matters in the casing, including added water and medicinal liquid formed after decoction) by means of the bottom, entering the space below the inner casing, and providing a middle cylinder 45 for accommodating the electric heating element 30 and realizing isolation and diversion of ascending medicinal liquid.

Any material capable of filtering and supporting the dregs can be adopted for the bottom of the medicine, for example, a metal pore plate (or a screen plate) or a metal filter screen (a filter screen frame can be arranged for fixing and supporting the filter screen if necessary), the through holes on the pore plate and the mesh holes of the filter screen form filter holes of the bottom, the pore diameter/size of the filter holes are set according to the filtering requirement, the filtering effect is poor due to the overlarge pore diameter/size, and the resistance is increased due to the overlarge pore diameter/size, so that the circulation of the medicine liquid is hindered.

The bottom of the bottom plate can be a flat bottom (see fig. 3) or can be a cone (frustum) with an upward convex middle part (see fig. 1 and 2). When the bottom of the pan is conical, frustum-shaped or other convex bottom with the middle part protruding downwards, a gap with a small middle large periphery is formed between the bottom of the cover and the bottom of the pan, and water passing through the filter screen (the bottom of the cover) enters the gap and then flows into the inner hole of the middle cylinder to realize circulating flow. Therefore, with this configuration, the outer edge (periphery) of the casing bottom can be directly supported on the outer edge (the peripheral area of the casing bottom adjacent to the side wall of the casing) of the casing bottom (see fig. 2), and no support (inner casing bracket) for the inner casing is provided.

In the case of a flat bottom, if the inner casing is supported without a support structure/bracket, the bottom is stuck to the bottom, which hinders the flow of water. Thus, the inner housing 46 may be provided in the casing, for example, a wire holder may be provided in an existing pressure cooker, supported between the inner housing and the bottom of the pan, and a certain space may be provided below the bottom of the casing.

When the lower port of the middle tube is a bell mouth, the bell mouth and the middle tube communication hole (hole wall) at the bottom of the casing can be in smooth transition to form a smooth plane (see fig. 2). When the lower port of the middle tube is a straight port, a rib may be formed at the junction of the middle tube and the casing bottom (see fig. 1 and 3). Under the background of the prior art, the middle cylinder and the casing bottom can be integrally formed in a pressure processing mode, or can be manufactured into two independent pieces, and then the two independent pieces are continuously sealed and welded into a whole and polished to be smooth.

Depending on the user's needs, the inner casing may be provided without a side wall, in which case the water outlet 14 is preferably provided on the side wall of the casing below the inner casing or on the bottom of the casing (e.g., the center of the bottom). When in use, the inner container is placed into the shell, then the medicine is placed into the shell, the placed medicine is accumulated on the upper surface of the bottom of the casing, and after the medicine is boiled, the valve of the water outlet is opened to lead out the medicine liquid. And then taking out the inner casing to remove the residues in the shell, and cleaning.
