[0002] In prior art, air humidification technology is widely used in many fields such as home, industry, agriculture, etc. Among them, wet curtain humidification technology is favored due to its high efficiency, energy saving and other advantages. As the core component of the wet curtain humidification system, the convenience of installation and maintenance of the wet curtain humidification assembly directly affects the performance and user experience of the entire system.

[0003] At present, the common wet curtain assembly usually needs to be directly inserted into the installation cavity of the humidifier shell and fixed by buckle or screw, but when the wet curtain assembly is still connected with accessories such as water supply pipe and water distribution pipe, the installation process needs to be accurately aligned with multiple connection points, which is tedious and time-consuming, and installation errors are easy to occur. That is, the alignment operation needs to consume a lot of time and energy, which reduces the assembly efficiency, and if forced installation is not aligned, it may cause damage to the components and cause unnecessary loss.

[0025] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings, it should be understood that the preferred embodiments described here are only used to illustrate and explain the present application, and are not used to limit the present application.

[0026] As Figures 1 to 5 shown, the first aspect, the present application embodiments provide a wet curtain assembly installation positioning structure, comprising:

[0027] The shell 10 is the main structure of the humidifier, the inside of the shell 10 is provided with an installation cavity 20, the installation cavity 20 is used for accommodating and fixing the wet curtain assembly. On the top of the installation cavity 20, an integral vertical protruding limiting block 30 is provided. The limiting block 30 can be integrally formed with the shell 10 by injection molding process or the like.

[0028] The wet curtain framework 40 is the main support structure of the wet curtain assembly, and the top of the wet curtain framework 40 is provided with an annular protrusion 50. A part of the water distributor on the top of the wet curtain framework 40 constitutes the annular protrusion 50. The circumferential sidewall of the annular protrusion 50 is provided with a positioning notch 51 matched with the limiting block 30, the positioning notch 51 is used to match with the limiting block 30 on the shell 10, in order to facilitate installation and ensure the stability of the rotating cooperation, the positioning notch 51 adopts the groove structure penetrating the upper and lower surfaces of the annular protrusion 50 along the vertical direction, and the arc surface transition design is adopted between the notch bottom surface and the sidewall. The structure of the arc surface transition can better guide the rotation assembly of the annular protrusion 50 to the right position, and improve the smoothness in the rotation process.

[0029] Wherein, the positioning notch 51 of the annular protrusion 50 and the limiting block 30 constitute a limiting cooperation structure, when the wet curtain framework 40 is inserted into the installation cavity 20, the positioning notch 51 needs to be aligned with the limiting block 30 first, then the wet curtain framework 40 is rotated, so that the limiting block 30 is embedded in the positioning notch 51, thereby realizing the rapid positioning of the wet curtain framework 40 and the shell 10. When the positioning notch 51 is aligned with the limiting block 30, the water distribution pipe 22 is also aligned with the water supply pipe 21, so that the insertion installation between the water distribution pipe 22 and the water supply pipe 21 can be accurately completed. When the circumferential sidewall of the annular protrusion 50 is not aligned with the limiting block 30, the sidewall of the limiting block 30 is abutted, so as to limit the depth of the wet curtain framework 40 inserted into the installation cavity 20, and avoid forced installation under the misalignment condition. This structure also effectively limits the installation direction of the wet curtain framework 40.

[0030] Specifically, as Figure 1 , Figure 4As shown, a water supply pipe 21 is provided at the bottom of the installation cavity 20, and a water distribution pipe 22 is provided on the wet curtain frame 40 to cooperate with the water supply pipe 21. When the positioning notch 51 and the limiting block 30 are aligned and assembled, the wet curtain frame 40 can be inserted and installed in the installation cavity 20, and the water distribution pipe 22 can be aligned and inserted with the water supply pipe 21. When the positioning notch 51 and the limiting block 30 are misaligned and assembled, the circumferential sidewall of the annular protrusion 50 abuts against the sidewall of the limiting block 30 to limit the depth of the wet curtain frame 40 inserted into the installation cavity 20. In this way, since the positioning notch 51 penetrates the upper and lower surfaces of the annular protrusion 50 vertically, when assembling the wet curtain frame 40, the operator does not need to painstakingly align the water distribution pipe 22 and the water supply pipe 21. He only needs to align the positioning notch 51 on the annular protrusion 50 with the limiting block 30 outside the installation cavity 20, insert it, and rotate it. This greatly simplifies the installation steps, improves the assembly efficiency, and avoids the previous cumbersome alignment operation, making the installation process simpler and more convenient. In this embodiment, both the water distribution pipe 22 and the water supply pipe 21 are arranged vertically.

[0031] In some embodiments, such as Figure 1 , Figure 2 As shown, the circumferential sides of the positioning notch 51 are rounded. This rounded corner structure guides the limiting block 30 smoothly into the positioning notch 51 and reduces rotational resistance, thereby improving assembly efficiency. In this embodiment, as... Figure 2 As shown, the circumferential sides of the limiting block 30 are rounded. The rounded corners reduce friction and wear between the limiting block 30 and the positioning notch 51 during the mating process.

[0032] In some embodiments, such as Figure 2 As shown, the top of the limiting block 30 serves as a contact terminal. In this way, the limiting block 30 can be used as a contact terminal to connect to the operation panel on the top of the humidifier, achieving the integration of structural and electrical functions. This eliminates the need for additional contact design, saves space, and avoids the use of separate contacts to reduce the number of parts.

[0033] In some embodiments, such as Figure 2 , Figure 5As shown, a radially extending support plate 23 is provided near the top of the housing 10. The support plate 23 defines the opening of the mounting cavity 20. The outer diameter of the annular protrusion 50 is larger than the inner diameter of the opening of the mounting cavity 20, and the lower surface of the annular protrusion 50 abuts against the support plate 23. Thus, the outer diameter of the annular protrusion 50 is designed to be larger than the inner diameter of the opening of the mounting cavity 20. This size ensures that the evaporative cooling pad frame 40 cannot be directly inserted into the mounting cavity 20, but can only be installed by engaging the positioning notch 51 with the limiting block 30. Simultaneously, the support plate 23 at the edge of the opening of the mounting cavity 20 provides a planar structure that abuts against the lower surface of the annular protrusion 50 to form a stable support structure. This effectively bears the weight of the evaporative cooling pad frame 40 and the forces during installation, preventing the evaporative cooling pad frame 40 from shaking after installation, ensuring a stable and reliable installation. In this embodiment, as... Figure 2 As shown, the side wall of the limiting block 30 is flush with the side wall of the support plate 23.

[0034] Secondly, embodiments of this application provide a humidifier, including an installation and positioning structure for the evaporative cooling pad assembly as described in the first aspect. Those skilled in the art will understand that, for the sake of convenience and brevity, the specific working process of the humidifier described above can be referred to the corresponding process in the aforementioned embodiments of the evaporative cooling pad assembly installation and positioning structure, and will not be repeated here.

[0035] The evaporative cooling pad assembly installation and positioning structure and humidifier provided in this embodiment utilize a limiting block and annular protrusion to form a limiting fit structure. This eliminates the need for complex multi-point alignment operations; installation can be quickly completed simply by aligning the positioning notch of the evaporative cooling pad frame with the limiting block on the housing and rotating it into place. This significantly improves assembly efficiency and reduces manual labor intensity and assembly costs. Simultaneously, this limiting fit structure effectively restricts the installation direction of the evaporative cooling pad frame, preventing component damage and performance degradation due to incorrect installation. Furthermore, the mutual obstruction between the limiting block and the annular protrusion when misaligned effectively prevents the evaporative cooling pad frame from being forcibly inserted, thereby further ensuring the reliability and safety of the installation.
