[0020] In order to better understand the purpose, structure and function of the present invention, the following Figure 1-3 , an evaporator assembly and an air purifier of the present invention are further described in detail.

[0021] like Figure 1-Figure 3 As shown, the present invention provides an evaporator assembly, including a filter 4, a wet curtain 5 is arranged inside the filter 4, air flows through the wet curtain 5 through the filter 4, and is output to the outside after being cooled by the wet curtain 5. It also includes a partition 3 for blocking water on one side of the wet curtain, the partition 3 is arranged between the filter 4 and the wet curtain 5, and a vent is arranged on the partition 3.

[0022] The present invention provides an evaporator assembly, wherein the top of the partition 3 is connected to an upper cover 1, the bottom of the partition 3 is connected to a lower cover 2, the filter 4 is fixed on the partition 3 on the upstream side of the airflow direction, and the wet curtain 5 is fixed on the partition 3 on the downstream side of the airflow direction. After being filtered by the filter 4, the air flows through the partition 3 and the wet curtain 5, and is output to the outside after being cooled by the wet curtain 5. The filter 4, the wet curtain 5 and the partition 3 are designed as an integrated composite filter, which simplifies assembly and further reduces the volume of the evaporator assembly.

[0023] Furthermore, at least two retaining ribs are provided on the upper surface of the upper cover 1, and a water receiving groove 21 is formed between the retaining ribs and the upper surface of the upper cover 1. The retaining ribs extend out of the lower surface of the upper cover 1. At least two retaining ribs are provided on the upper surface of the lower cover 2 at the same position as the upper cover 1, and a water dividing groove 11 is formed between the retaining ribs and the upper surface of the lower cover 2. The retaining ribs are used to prevent water from overflowing from above. The upper cover 1, the partition 3 and the water receiving groove 21 form a groove for accommodating the wet curtain 5, which accommodates the wet curtain 5, so that the humidifying water flows into the wetted humidifying wet curtain 5 from the upper water hole 111, and the excess water is discharged from the lower water hole 111. The porous partition 3 prevents the wetted wet curtain 5 from wetting the filter.

[0024] The evaporator assembly also includes a water receiving tank 21 integrally provided with the upper cover 1 and a water dividing tank 11 integrally provided with the lower cover 2, wherein the water dividing tank 11 is provided at the upper end of the partition 3, and the water receiving tank 21 is provided at the lower end of the partition 3, and the water in the water dividing tank 11 can enter the water receiving tank 21 through the wet curtain 5. When the evaporator assembly is applied to the air purifier product, it effectively prevents the water from flowing to places other than the wet curtain 5 and the water tank due to the poor matching between the water dividing tank 11 or the water receiving tank 21 and the partition 3, and the integrated design also facilitates the user to quickly clean and improve the user experience.

[0025] The upper cover 1, the partition 3 and the lower cover 2 form a groove for accommodating the filter screen 4 and the wet curtain 5. A plurality of water holes 111 are arranged at the bottom of the water receiving groove 21 of the upper cover 1, and a plurality of water receiving holes 211 are arranged at the bottom of the water dividing groove 11 of the lower cover 2. A wet curtain 5 is arranged in the groove formed by the water receiving groove 21 of the upper cover 1, the water dividing groove 11 of the lower cover 2 and the partition 3.

[0026] Furthermore, filter screen 4 and wet curtain 5 are sequentially arranged on both sides of partition 3, partition 3 is arranged between filter screen 4 and wet curtain 5, multiple vents are arranged on partition 3, multiple vents are arranged in an array with equal spacing, each vent is inclined, and the end of each vent adjacent to filter screen 4 is higher than the end adjacent to wet curtain 5. The vents of partition 3 are oriented in a direction that the inside is low and the outside is high, so as to prevent water from flowing out from the inside and wetting filter screen 4. When humidification water flows from water receiving tank 21 into humidification wet curtain 5, excess water is discharged from water receiving hole 211 below, and partition 3 prevents wetting wet curtain 5 from wetting filter screen.

[0027] Preferably, the partition 3 is made of a non-absorbent material, such as plastic, etc., to separate the wetted wet curtain 5 and the filter screen. The wet curtain 5 is made of a water-absorbent material. The partition 3 has a thickness, and the thickness of the partition 3 is 2.5 mm to 5 mm, which further separates the filter screen 4 and the wet curtain 5 to prevent the wet curtain 5 from wetting the filter screen 4.

[0028] As a preferred embodiment of the invention of an evaporator assembly, the upper cover 1 and the lower cover 2 are annular plate structures, the partition 3 is a cylindrical porous plate structure, the wet curtain 5 and the filter 4 are formed as a cylindrical wet curtain 5 and a cylindrical filter 4, and the filter 4, the partition 3 and the humidifying wet curtain 5 are arranged in sequence from the outside to the inside. When the evaporator assembly is working, the overall airflow flows from the outside to the inside in sequence. The airflow first passes through the filter 4 for filtration, and then the clean air passes through the partition 3, and then passes through the moistened humidifying wet curtain 5, bringing out the water vapor in the wet curtain 5, and finally becoming clean moist air.

[0029] The present invention also discloses an air purifier, comprising the above-mentioned evaporator assembly. The present invention provides an integrated humidification and filtration composite filter, which simplifies the assembly of the purifier and further reduces the volume of the whole machine.

[0030] It is to be understood that the present invention is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
