BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 is a schematic view showing a principle of a private part cleaning device according to the present disclosure; and

(2) FIG. 2 is a schematic structural view of a heating apparatus according to the present disclosure.

DETAILED DESCRIPTION OF EMBODIMENTS

(3) The heating apparatus and the private part cleaning device using the apparatus are described hereinafter in conjunction with the drawings.

(4) As illustrated in FIG. 1, the private part cleaning device according to the present disclosure includes a cleaning component 300, a water supply component 100 and a heating apparatus 200. The cleaning component 300 is configured to spray water to a private part of a human body. The water supply component 100 is configured to supply the water to the cleaning component 300. The heating apparatus 200 is configured to heat the water supplied to the cleaning component 300 instantly.

(5) FIG. 2 is a schematic structural view of a heating apparatus according to the present disclosure. The heating apparatus 200 includes a housing 210, a cylindrical heat conducting member 220 accommodated in the housing, and a heating member 230 accommodated in the heat conducting member 220. The housing is provided with a water inlet 211 and a water outlet 212. An inner surface of the housing 210 has a spiral shape winding along an outer peripheral surface of the heat conducting member 220. A first cavity 240 is formed between an outer surface of the heating member 230 and an inner surface of the heat conducting member 220, and a second cavity 250 is formed between an outer surface of the heat conducting member 220 and an inner surface of the housing 210. An inlet of the second cavity 250 is in communication with an outlet of the first cavity 240. The water flow flows into the heating apparatus via the water inlet 211 and is heated by the heating member 230 when flowing through the first cavity 240, then flows through the second cavity 250 and performs heat exchange with the water flow in the first cavity 240 via the heat conducting member 220, and flows out via the water outlet 212 finally.

(6) The heating apparatus 200 further includes a temperature detector 260 and a controller. The temperature detector 260 is configured to detect a temperature of the water flow in the second cavity. The controller is configured to perform heating control on the heating member 230 based on the temperature detected by the temperature detector 260. Preferably, the temperature detector 260 is arranged at the inlet of the second cavity 250, such that the temperature is fed back to the controller quickly, and thus the controller performs control quickly. The temperature of the heated water can be detected by the temperature detector 260 quickly and fed back to the controller. The controller can adjust a heating power of the heating member 230 in response to the feedback, such that the controller can know the temperature of the water expected by a user quickly. In a case that the temperature of the water exceeds a specified temperature, the temperature detector 260 feeds back a signal indicating the excessive temperature to the controller, and the controller cuts off power supplied to the heating member 230.

(7) The heat conducting member 220 is made of a metal heat conducting material, such that heat exchange is fully performed between the fluid in the second cavity 250 and the fluid in the first cavity 240. The temperature after heating is fed back to the temperature detector 260 accurately and quickly, and an outlet water temperature is uniform, thereby avoiding the discomfort caused by a temperature sudden change in some extent. Preferably, the heat conducting member 220 is made of copper. Since copper has an excellent heat conduction performance and corrosion resistance, heat exchange is performed well between the water in the second cavity 250 and the water in the first cavity 240.

(8) The action process of the private part cleaning device according to the present disclosure is as follows. When partial cleaning is required, the water supply component 100 is turned on, and water flows from the outside into the water supply component 100, then flows into the heating apparatus 200. The water conveyed to the heating apparatus 200 is heated to a default temperature instantly while flowing in the heating apparatus 200. Then the water is conveyed to the cleaning component 300 and sprayed to a private part of a human body for cleaning. A water path of the water supply component 100 is turned off after cleaning is completed.

(9) The flowing of the water in the heating apparatus 200 is described specifically hereinafter. The water flows via the water inlet 211 of the housing into the inner surface of the heating member 230, then flows through the first cavity 240 formed between the outer surface of the heating member 230 and the inner surface of the heat conducting member 220. In this case, the water flow is heated by the heat generated on the outer surface of the energized heating member 230 while flowing in the first cavity 240. The heated water flow flows through the second cavity 250 formed between the outer surface of the heat conducting member 220 and the inner surface of the housing 210. In this case, the water flow is supplied to the temperature detector 260 for temperature detection. The temperature detector 260 feeds back the detected temperature data signal to the controller. The controller compares the detected temperature with the default preset temperature, and adjusts a heating power of the heating member 230 to make the detected temperature consistent with the default preset temperature.

(10) Meanwhile, the water flow performs heat exchange with the water flow in the first cavity 240 via the heat conducting member 220 while flowing in the second cavity 250. Since the inner surface of the housing 210 has a spiral shape, the water flow presents a spiral shape extending along the outer surface of the heat conducting member 220. In this case, the water flow has a long flow distance. Not only a mixing time for the water flow itself in the second cavity 250 is long, but also a time for performing heat exchange between the water flow in the second cavity 250 and the water flow in the first cavity 240 arranged in the heat conducting member 220 is long. The water temperature does not change suddenly, and the water flow mixed uniformly flows out via the water outlet 212 finally.

(11) The heat conducting member of the heating apparatus according to the present disclosure may also have upper and lower surfaces with a flat shape or other shape. The heating member is accommodated in a cavity formed between the housing and the lower surface of the heat conducting member, and a second cavity is formed between the upper surface of the heat conducting member and the housing. The upper and lower surfaces here are relative, and the structure of the heat conducting member is not specifically limited.

(12) Compared with the conventional technology, the heating apparatus according to the present disclosure has a small volume since it is not necessary to provide a buffer water tank with a large volume, which is beneficial to a miniaturization of the heating apparatus and the private part cleaning device. When a temperature of the heating apparatus suddenly rises, the controller can quickly acquire the feedback from the temperature detector, and the controller performs heating control on the heating member. The heat exchange is performed between the fluid in the second cavity before the heating control and the fluid in the first cavity after the heating control, such that the temperature can be rapidly adjusted. When abnormal situations occur, such as water supply cutoff, a temperature in the first cavity rises rapidly. Since there is good heat exchange between the first cavity and the second cavity, the temperature in the second cavity also rises rapidly. Then the temperature detector arranged in the second cavity detects the abnormal situations and feeds back the situation to the controller quickly, and the controller cuts off power supplied to the heating apparatus to avoid security risks. In this way, abnormity detection can be performed without adding other devices to the heating apparatus according to the present disclosure, such as a flowmeter, such that the heating apparatus has fewer components and a low cost.
