Description

Heat-preservation circulating water bathtub Technical Field The utility model relates to a bathtub, in particular to a heat-preservation circulating water bathtub. Background Currently, there are many types of bathtubs on the market that aim to provide a comfortable use experience. Patent publication number CN202223113U discloses a bathtub having a tub with a structure comprising an annular side wall and a bottom surface. In order to improve the comfort and stability of the human body in the bathtub, the bottom surface is provided with a convex part, two sides of the bottom surface are provided with concave parts respectively, and the side wall is provided with a bulge part. These designs are intended to provide proper body support for the user and effectively prevent the human body from slipping in the bathtub during water filling or use, thereby reducing the risk of runaway and improving safety of use. However, such bathtubs of the prior art are typically constructed with solid sidewalls. Such solid sidewalls, while simple in construction, provide poor insulation. In the use, the hot water in the bathtub can lose heat through the lateral wall more rapidly, leads to the temperature to drop rapidly, and the user needs to add hot water frequently in order to maintain required temperature, and this not only wastes the energy, has also influenced the experience of long-time comfortable shower. Disclosure of utility model In view of the above, the utility model aims to provide a heat-preserving circulating water bathtub, which achieves the aim of improving heat preservation. In order to solve the technical problems, the technical scheme is that the heat-preservation circulating water bathtub comprises an inner cylinder body, an outer cylinder body and a connecting part, wherein the inner cylinder body is positioned in the outer cylinder body, one side of the connecting part is connected with the outer wall of the inner cylinder body, the other side of the connecting part is connected with the inner wall of the outer cylinder body, a heat-preservation cavity is formed among the outer cylinder body, the connecting part and the inner cylinder body, and a foaming heat-preservation layer is filled in the heat-preservation cavity. The technical scheme is realized, a heat preservation cavity is formed by the inner cylinder body, the outer cylinder body and the connecting part, and then a foaming heat preservation layer is injected into the cavity to expand and solidify the cavity. The foamed insulation layer creates an effective thermal barrier that significantly reduces the rate of heat transfer from the hot water within the tub to the external environment. Therefore, the water temperature in the bathtub can be kept warm for a longer time, the problem of quick heat loss of the solid side wall bathtub in the prior art is solved, and the experience of long-time comfortable bath of a user and the heat preservation performance of the bathtub are improved. As a preferable scheme of the utility model, a drain hole is arranged on the bottom wall of the inner cylinder body, a drainer is arranged in the drain hole, a drain pipe is fixedly connected to the side wall of the outer cylinder body, one end of the drain pipe, which is far away from the outer cylinder body, is fixed on the bottom surface of the inner cylinder body, and the drain hole is positioned in the drain pipe. According to the technical scheme, when a user opens the drainer to drain water, water in the inner cylinder body flows out through the drain hole of the bottom wall. Since the drain hole is located inside the drain pipe, the water flow is directly introduced into the drain pipe. The water flows down the drain pipe and eventually drains from the outer cylinder side wall. The water draining pipe has stable and sealed water draining passage, and can ensure water flow to pass through the heat insulating cavity reliably, prevent water from leaking into the foamed heat insulating layer and protect the performance of the foamed heat insulating layer. As a preferable scheme of the utility model, a water inlet is formed in the side wall of the inner cylinder body, a water inlet pipe is fixedly connected in the water inlet, the end parts of a plurality of water inlet pipes are communicated with a water main through a flow divider, the water main is fixed on the side wall of the outer cylinder body, a water outlet is formed in the side wall of the inner cylinder body, a water outlet pipe is fixed on the water outlet, one end of the water outlet pipe, which is far away from the water outlet, is fixed on the side wall of the outer cylinder body, and the water inlet is higher than the water outlet. According to the technical scheme, water flow firstly enters the main water pipe, is distributed to the water inlet pipe through the flow divider, and is injected into the bathtub from the higher water inlet. The water in the bathtub flows out from the water outlet at the l
