Technical Field

[0001] This utility model relates to the field of water purification equipment technology, and in particular to a shell structure and a water purification device containing the same. Background Technology

[0002] The performance and structural design of water purification equipment directly affect its ease of use and maintenance costs. The construction of the middle shell is particularly crucial, as it requires the assembly of various core components such as heating elements, power supply components, and electronic control elements.

[0003] In existing technologies, the shell structure design of water purification equipment tends to be integrally cast or injection molded. While this can ensure structural integrity to a certain extent, it also presents several significant drawbacks. First, the integrally molded shell is prone to uneven filling and shrinkage deformation during the injection molding process, affecting the dimensional accuracy and sealing performance of the shell. Second, the complex internal structure results in high mold design costs and complex mold maintenance. Once the mold is damaged, the repair cycle is long, threatening the continuity of production. Third, when internal parts of the equipment need repair or replacement, the integral or tightly assembled shell often requires destructive disassembly, greatly increasing the difficulty and cost of subsequent maintenance.

When the power assembly 15 is working, the heat generated can be dissipated through the left-facing opening 11121, ensuring the stability and reliability of the housing structure 1.

[0077] Further, please refer to Figure 9 As shown, the housing structure 1 also includes an outer shell 16 with openings at both ends and a rear cover plate 17. The rear cover plate 17 is disposed opposite to the front cover plate 13 and its two ends are respectively connected to the first middle shell 11 and the second middle shell 12. The outer shell 16 covers the first middle shell 11 and the second middle shell 12 and its two openings are covered by the front cover plate 13 and the rear cover plate 17.

[0078] Specifically, the connection between the front cover plate 13 and the rear cover plate 17 and the first middle shell 11 and the second middle shell 12 can enhance the stability of the entire shell structure 1. The outer shell 16 can prevent external dust, moisture and other impurities from entering the components inside the middle shell, thereby protecting the internal components from damage. Moreover, the outer shell 16 with openings at both ends is covered by the front cover plate 13 and the rear cover plate 17, which not only makes the assembly and disassembly process more convenient, but also makes the shell structure 1 more resistant to deformation and damage when subjected to external forces, thereby improving the durability and reliability of the shell structure 1.

[0079] Example 2

[0080] The second embodiment of this utility model discloses a water purification device, which includes the shell structure 1 in the first embodiment. The function of the water purification device provided in the second embodiment of this utility model is the same as that of the shell structure 1 provided in the first embodiment, and will not be repeated here.

[0081] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0082] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
