[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figures 1 to 3 As shown, a preferred embodiment of the antifreeze water purification device of this utility model includes a housing 1, a heating device 2, and a filtering device 3. Both the heating device 2 and the filtering device 3 are housed within the housing 1. The housing 1 is equipped with a water inlet 101, a wastewater inlet 102, and a water outlet 103. The water inlet 101 is connected to the heating device 2, through which raw water enters the heating device 2, which heats the raw water. The heating device 2 is connected to the filtering device 3 via a connecting pipe, and the heated raw water enters the filtering device 3 for filtration. The heating device 2 and the filtering device 3 are electrically connected, allowing the heating device 2 to supply power to the filtering device 3. The filtering device 3 is simultaneously connected to both the water outlet 103 and the wastewater inlet 102. Drinking water produced by the filtering device 3 is discharged from the housing 1 through the water outlet 103, and wastewater produced by the filtering device 3 is discharged through the wastewater inlet 102. The heating device 2 is used to heat the raw water, ensuring that the raw water will not condense and become stagnant due to low temperature within the entire filtration device 3. This ensures that the filtration device 3 can always purify the raw water and continuously discharge clean water, without being affected by low external temperatures.

[0024] The heating device 2 includes a fuel cell 21, a circulating pump 22, and a heat exchanger 23. The fuel cell 21 generates electricity and is electrically connected to the filter device 3, supplying power to the filter device 3. The heat exchanger 23 has a first medium inlet, a second medium inlet, a second medium outlet, and a second medium outlet. The first medium inlet of the heat exchanger 23 is connected to the fuel cell 21 via a connecting pipe. The first medium outlet of the heat exchanger 23 is connected to the water inlet of the circulating pump 22 via a connecting pipe. The second medium inlet is connected to the water inlet 101 via a connecting pipe. The second medium outlet is connected to the filter device 3. The water outlet of the circulating pump 22 is connected to the fuel cell 21 via a connecting pipe. The electrolyte of the fuel cell 21 enters the heat exchanger 23 through a connecting pipe, and the water to be purified enters the heat exchanger 23 through the water inlet 101. The electrolyte heats the water to be purified through the heat exchanger 23, while simultaneously cooling the electrolyte. The heated water is discharged from the second medium outlet and enters the filter device 3 for purification. After heat exchange in the heat exchanger 23, the electrolyte is discharged from the first contact outlet and enters the circulation pump 22. The circulation pump 22 pumps the cooled electrolyte into the fuel cell 21, thus ensuring that the fuel cell 21 has sufficient electrolyte and that the electrolyte in the fuel cell 21 is kept within the operating temperature range to prevent malfunctions due to excessive temperature.

[0025] like Figure 4As shown, the fuel cell 21 is provided with a groove 211, which is used to cooperate with the housing 1 to position the fuel cell 21 and also serves as a point of leverage when picking up the fuel cell 21. Grooves 211 are provided on both sides of the fuel cell 21 to facilitate more stable handling. The fuel cell 21 is also provided with positioning posts 212, located at the bottom of the fuel cell 21. The positioning posts 212 are arranged in two rows along the width direction of the fuel cell 21, and are used to cooperate with the housing 1 to limit the swaying of the fuel cell 21 in the width direction.

[0026] like Figures 5 to 7As shown, the housing 1 includes a frame 11 and an outer shell 12. The outer shell 12 is fixed to the frame 11, forming a first chamber and a second chamber. The filter device 3, heat exchanger 23, and circulation pump 22 are all located in the first chamber, and the fuel cell 21 is located in the second chamber. A mounting plate 13 is also provided on the frame 11, corresponding to the first chamber, and the circulation pump 22 is mounted on the mounting plate 13. A positioning spring 14 is also provided on the mounting plate 13, corresponding to the second chamber. The positioning spring 14 is used to position the fuel cell 21. The groove 211 on the fuel cell 21 cooperates with the positioning spring 14, thus positioning the fuel cell 21 for quick placement. In other embodiments, the positioning spring 14 can also be fixed to the frame 11, and the installation position of the positioning spring 14 can be selected according to actual needs. The mounting plate 13 is also equipped with clips (not shown in the figure), which are used to fix the nanofiltration membrane assembly 325, the ultrafiltration membrane assembly 312, and the security filter 313. The positioning post 212 of the fuel cell 21 cooperates with the frame 11 to confine the positioning post 212 within the frame 11, thereby confining the fuel cell 21 within the frame 11. The frame 11 is formed by fixing multiple profiles, which is convenient for processing and manufacturing; the two profiles that cooperate with the positioning post 212 are L-shaped, which also confines the lower end of the positioning post 212. The frame 11 is provided with a handle 15 for easy lifting of the entire device, and the handle 15 passes through the outer shell 12 and connects to the frame 11. The water inlet 101, wastewater inlet 102, and water inlet 102 are all located on the outer shell 12. The outer casing 12 includes a frame 121 and a panel 122. The frame 121 is fixed to the skeleton 11. The frame 121 consists of two left and right sides, and the panel 122 consists of two left and right sides. The panel 122 is fixed to the frame 121. Specifically, the left panel 122 is fixed to the left frame 121, and the right panel 122 is fixed to the right frame 121. The periphery of the panel 122 extends towards the frame 121 to form fixing posts 1221. The frame 121 is provided with fixing blocks 1211. The fixing posts 1221 are detachably fixed to the fixing blocks 1211, usually by screws. Thus, when maintenance is required, the fuel cell 21 can be removed and the internal structure can be maintained simply by disassembling the panel 122.

[0027] By directly exchanging heat between the electrolyte of fuel cell 21 and the raw water, the temperature of the raw water entering the filter device 3 can be guaranteed to be above 0°C. This ensures that the water can flow within the filter device 3 without condensing into ice, enabling continuous filtration to produce potable water. The outer casing 12 locks in the heat, further ensuring that the water temperature remains above 0°C during the filtration process, guaranteeing smooth operation.

[0028] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structure made using the contents of this utility model specification and drawings, whether directly or indirectly applied to other related technical fields, shall also be within the patent protection scope of this utility model.
