[0069] A plurality of water purification components 11 are installed in the box body 1; the air duct 33 is opposite to the cavity region between adjacent water purification components 11, so that the negative ions can go deeper into the inside of the box body 1, further purify the odor in the box body 1 in a directional manner, and improve the taste and safety of drinking water.

[0070] Here, the working principle of the odor removal device 3 is that the generated negative ions combine with odor particles in the box, so that the odor particles are charged with negative electricity, and are attracted to each other to form larger particles, which eventually settle under the action of gravity; the negative ions can also react with harmful gases and odor molecules in the box to reduce odor.

[0071] In this embodiment, the position of the odor removal device 3 is close to the position of the water purification component 11 that generates heat during operation, so that the fan 32 of the odor removal device 3 can be used to cool the water purification component 11 that generates heat during operation, and the hot air generated by the water purification component 11 can be used to further promote the circulation of air in the box 1, thereby enhancing the odor removal effect.

[0072] Please refer to Figure 4 In this embodiment, the odor removal device 3 further includes a fixing member 34, the fan 32 and the negative ion generator assembly 31 are connected to the middle part of the fixing member 34, and the two ends of the fixing member 34 are connected to the two ends of the inner side surface of the lower door panel 2. A predetermined cavity 35 is reserved between the fixing member 34 and the lower door panel 2, and the air duct 33 passes through the predetermined cavity 35. In this way, the fan 32 and the negative ion generator 313 can be fixed at the middle part of the inner side surface of the lower door panel 2, while maintaining a certain distance from the inner side surface of the lower door panel 2, so that the air in the box 1 can be sucked into the fan 32 through the predetermined cavity 35, and then blown to the negative ion generator 313 along the air duct 33, thereby further optimizing the design of the air flow channel and effectively improving the circulation efficiency of the internal air.

[0073] In this embodiment, the middle part of the fixing member 34 is provided with a hole 341 corresponding to the positions of the fan 32 and the negative ion generator assembly 31. The hole 341 is a waist-shaped hole extending along the length direction of the fixing member 34, which can provide the fan 32 with a larger air intake as much as possible while causing less loss of strength of the fixing member 34, thereby further optimizing the design of the air flow channel.

[0074] In this embodiment, the fan 32 is fixed to the middle part of the fixing member 34 by bolts, so that the disassembly and maintenance of the fan 32 can be realized in a relatively simple structure.

[0075] In this embodiment, the negative ion generator assembly 31 is fixed to the middle part of the fixing member 34 by bolts, so that the disassembly and maintenance of the negative ion generator assembly 31 can be realized in a relatively simple structure.

[0076] In this embodiment, the two ends of the fixing member 34 are fixed to the two ends of the inner side surface of the lower door panel 2 by bolts, so that the disassembly and maintenance of the odor removal device 3 can be realized in a relatively simple structure.

[0077] In the embodiment, the negative ion generator assembly 31 comprises a negative ion generator 313 and a shell, the shell comprising a shell body 314, a boss 315 and a mounting 316 matching the shape of the negative ion generator 313; the negative ion generator 313 is embedded in the mounting 316, the mounting 316 is located inside the shell body 314, and the boss 315 is connected to the outside of the shell body 314; the boss 315 is provided with a mounting hole 3151. In this way, the cooperation of the shell body 314 and the mounting 316 can better protect the negative ion generator 313, improve the reliability and service life of the negative ion generator 313; the boss 315 on the shell is designed for easy installation and fixation, which improves the stability of the negative ion generator 313 and facilitates further directional purification of odors in the box body 1.

[0078] In the embodiment, the shell is made of plastic material as a whole, so that the weight of the negative ion generator assembly 31 is relatively light, and the deformation of the fixing member 34 caused by the gravity of the negative ion generator assembly 31 for a long time is avoided.

[0079] In the embodiment, the lower door plate 2 is made of plastic material to further reduce the total weight of the lower door plate 2 and the deodorizing device 3, and avoid deformation of the connection between the lower door plate 2 and the box body 1 due to gravity. Of course, in other embodiments, the lower door plate can also be made of cold-rolled plate, galvanized plate or stainless steel plate to adapt to the site environment.

[0080] In the embodiment, the air outlet side 312 of the negative ion generator assembly 31 faces the box body 1, so that the negative ions can be directly sent to the odor source in the box body 1 from the air outlet side 312, maximizing the deodorizing effect of the negative ion generator 313.

[0081] In the embodiment, the lower door plate 2 is arranged below the water receiving box 5 of the water purifier, and the top is closely arranged with the water receiving box 5, which can improve the sealing performance of the inside of the box body 1 and reduce odor leakage.

[0082] In the embodiment, the water purifier further comprises a compression spring assembly 4, the fixed end 41 of the compression spring assembly 4 is connected to the lower part of the box body 1, and the movable end 42 of the compression spring assembly 4 is detachably connected to the bottom plate 22 of the lower door plate 2, facilitating the disassembly and maintenance of the lower door plate 2. At the same time, through the pressure provided by the spring 43 of the compression spring assembly 4, the sealing performance of the connection between the lower door plate 2 and the box body 1 can be improved, and odor leakage can be reduced.

[0083] In the embodiment, the fixed end 41 of the compression spring assembly 4 is a compression spring shell, the movable end 42 is a central shaft, and the spring 43 is fixed in the compression spring shell and connected to the central shaft. The bottom of the central shaft is connected to the bottom plate 22 of the lower door plate 2, which guides the up-and-down movement of the lower door plate 2 in a relatively simple structure.

[0084] In the embodiment, the movable ends 42 of the two compression spring assemblies 4 are connected to the bottom plate 22 of the lower door plate 2 near the two side plates of the cabinet 1, so that the lower door plate 2 is uniformly stressed during disassembly and assembly, the stability of the lower door plate 2 during disassembly and assembly is improved, and problems such as tilting and jamming of the lower door plate 2 during disassembly and assembly are further reduced.

[0085] In the embodiment, a ventilation opening is formed in the back plate of the cabinet 1 (the back plate is not shown in the figure for the purpose of showing the internal structure of the water purifier), so that the air generated by the fan 32 passes through the air duct 33 from the inner side of the lower door plate 2 of the cabinet 1, enters the negative ion generator assembly 31, and then enters the cabinet 1, and is discharged from the ventilation opening, thereby increasing the air exchange channel between the inside and outside of the cabinet 1 and enhancing the odor removal effect.

When the water purifier is turned on, the control portion controls the negative ion generator 313 to start working after the water purification component 11 operates for a first preset time period, and the fan 32 starts operating at the same time, thereby disturbing the air flow inside the cabinet and discharging the air inside the cabinet, so as to achieve the purpose of removing the odor inside the water purifier. When the negative ion generator 313 operates for a second preset time period, the control portion controls the negative ion generator 313 and the fan 32 to stop working, so as to achieve the purpose of energy saving.
