[0021] The following will be described in more detail with reference to the schematic diagram of the water bath with drainage function of the utility model, wherein the preferred embodiment of the utility model is shown, and it should be understood that the utility model described herein can be modified by a person skilled in the art, while still achieving the advantageous effects of the utility model. Therefore, the following description should be understood as being widely known to a person skilled in the art, and not as a limitation of the utility model.

[0022] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0023] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a water bath pot 2 with a drainage function, including an electrical base 1, a water bath pot 2 and a drainage component.

[0024] Specifically, the electrical base 1 is used to support the water bath 2 and electrically control the heating temperature of the water bath 2 .

[0025] The water bath pot 2 is mounted on the electrical base 1 . A heating tube 3 is provided inside the water bath pot 2 , and the heating tube 3 is electrically connected to the electrical base 1 .

[0026] The drainage assembly includes a connector disposed on the bottom surface of the water bath 2, and the connector is connected to the inside of the water bath 2. The output end of the connector is connected to a drain pipe 4, and the drain pipe 4 passes through the electrical base 1 and is installed with a drain valve 5.

[0027] In this embodiment, when the water in the water bath 2 needs to be drained, the drain valve 5 is opened, and the water in the water bath 2 is discharged along the drain pipe 4 and from the drain valve 5, thereby realizing the rapid drainage function of the water bath 2.

[0028] It should be noted that in order to ensure that the water in the water bath 2 can be drained and the drainage does not remain in the drainage pipe 4, the drainage end of the drainage pipe 4 is arranged to be inclined downward so that the drainage can be drained downward along the drainage pipe 4.

[0029] In addition, in order to prevent the water in the water bath 2 from overflowing, a marking line 6 for indicating the maximum water injection amount is provided on the inner wall of the water bath 2. During the water injection process of the water bath 2, the water injection amount must not exceed this marking line 6.

[0030] Furthermore, a positioning cavity 7 matching the water bath 2 is provided on the electrical base 1 , and a protective pad 8 for heat insulation is provided on the inner wall of the positioning cavity 7 .

[0031] Specifically, the water bath 2 is fixed in the positioning cavity 7, and the inner wall of the positioning cavity 7 can position and support the water bath 2, thereby ensuring that the water bath 2 can be stably located in the positioning cavity 7. In addition, in order to reduce the heat loss in the water bath 2, a protective pad 8 is arranged between the water bath 2 and the inner wall of the positioning cavity 7, and the heat transfer from the water bath 2 to the electrical base 1 is reduced by heat insulation, thereby reducing heat loss.

[0032] In order to facilitate the adjustment of the water bath heating temperature of the water bath pot 2, the electrical base 1 is also provided with an adjustment knob 9 for adjusting the heating power of the heating tube 3, and the adjustment knob 9 is connected in series with the heating tube 3. By turning the adjustment knob 9, the water bath heating temperature of the water bath pot 2 can be adjusted.

[0033] Furthermore, the bottom surface of the water bath pot 2 is arranged to be concave, and a drain outlet is arranged at the concave bottom of the water bath pot 2, and the connecting piece is detachably mounted on the drain outlet.

[0034] Specifically, the connecting piece includes an L-shaped elbow 10, an end of the L-shaped elbow 10 passes through the drain port from the bottom of the water bath 2 and is threadedly mounted with a sealing sleeve 11.

[0035] The L-shaped elbow 10 includes a bending portion 12 and a threaded connection portion 13 . The outer diameter of the threaded connection portion 13 is smaller than the outer diameter of the bending portion 12 . The threaded connection portion 13 passes through the drain port and is threadedly connected to the sealing sleeve 11 .

[0036] When installing the connector, the threaded connection part 13 on the L-shaped elbow 10 is passed through the drain port, and the sealing sleeve 11 is used for connection and sealing. At this time, the L-shaped elbow 10 is connected to the bottom of the water bath pot 2. In order to improve the sealing between the threaded connection part 13 and the bottom of the water bath pot 2, a sealing gasket 14 is provided between the sealing sleeve 11 and the inner bottom surface of the water bath pot 2.

[0037] Furthermore, the drain pipe 4 is threadably connected to the bent portion 12 .

[0038] Specifically, the electrical base 1 is provided with a support positioning hole matching the drain pipe 4. When installing the drain hole, the drain pipe 4 is passed through the support positioning hole and threadedly installed on the threaded connection portion 13. When the drain valve 5 needs to be maintained or replaced, the drain valve 5 and the drain pipe 4 can be directly removed from the threaded connection portion 13, which facilitates the replacement operation of the drain valve 5.

[0039] It should be noted that, while ensuring that the water in the water bath 2 can be drained along the drain pipe 4, the support positioning hole can be set in the middle of the electrical base 1, or at the bottom of the electrical base 1. Correspondingly, the drain pipe 4 can be set in the middle of the electrical base 1, or at the bottom of the electrical base 1.
