Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0031] The present application embodiment provides a water purification device for quickly replacing a filter element, such as Figure 1-8As shown, the water purification device includes a housing 1 and a filter element assembly 2, wherein the housing 1 has an inner cavity and an opening 11, and the filter element 2 is placed in the inner cavity. The opening 11 is covered with a lid 3, that is, the lid 3 can be removed from the opening 11. The filter element 2 includes a filter element 21, a waterway plate 22 and a base 23, wherein the waterway plate 22 is mounted on the base 23, and a filter element mounting seat 221 is provided on the waterway plate 22. The filter element 21 is inserted into the inner cavity through the opening 11, and a grip portion 213 is provided on the top of the filter element 21, and the bottom of the filter element 21 is detachably mounted with the filter element mounting seat 221. When installing the filter element 21, first insert the bottom of the filter element 21 from the opening 11, insert the filter element 21 into the inner cavity, grab the grip portion 213 by hand, and rotate the filter element 21 clockwise so that the bottom of the filter element 21 is mounted with the filter element mounting seat 221. When the filter element 21 needs to be replaced, the gripper 213 is grasped, the filter element 21 is rotated counterclockwise to separate the bottom of the filter element 21 from the filter element mounting seat 221, and then the filter element 21 is extracted from the opening 11. The water purification device of the present application can directly and quickly disassemble the filter element without using other auxiliary tools.

[0032] It should be noted that a water inlet and a water outlet are provided at the bottom of the filter element 21, and a water inlet connection port and a water outlet connection port are correspondingly provided on the filter element mounting seat 221. After the filter element 21 is installed on the filter element mounting seat 221, the water path between the inside of the filter element 21 and the waterway plate 22 can be connected.

[0033] like Figure 4 and Figure 5 As shown, the filter element 21 is provided with a buckle 211 and a first protrusion 212, and the filter element mounting seat 221 is provided with a guide groove 2211, a slot 2212 and a first limiting groove 2213, the guide groove 2211 is communicated with the slot 2212, when installing the filter element 21, the bottom of the filter element 21 is inserted into the opening 11, the buckle 211 is located in the guide groove 2211, the grip portion 213 is grasped, the filter element 21 is rotated clockwise, the buckle 211 slowly slides into the slot 2212, when the filter element 21 is installed on the filter element mounting seat 221, the buckle 211 is located in the slot 2212, and the first protrusion 212 is located in the first limiting groove 2213. When removing the filter element 21, rotate the filter element 21 counterclockwise, the buckle 211 disengages from the slot 2213, and slowly slides into the guide groove 2211. At this time, the first protrusion 212 also disengages from the first limiting groove 2213, and then the filter element is taken out from the opening 11.

[0034] Further, such as Figure 3 and Figure 8 As shown, the filter element assembly 2 further includes a filter element sleeve 24, which is mounted on the base 23. The filter element sleeve 24 is provided with a cavity 241, which is located below the opening 11. The filter element 21 is inserted into the cavity 241 through the opening 11. By providing the filter element sleeve 24, the filter element 21 can be more stably mounted on the waterway plate 22, and the upper end of the filter element 21 can be prevented from tilting, and the installation and removal of the filter element 21 are also more convenient.

[0035] Specifically, the filter cartridge sleeve 24 is provided with a positioning column 242, and the base 23 is provided with a screw column 231. The positioning column 242 is inserted into the screw column 231 to fix the filter cartridge sleeve 24 on the base 23. The waterway plate 22 is provided with a protrusion 222, and the filter cartridge sleeve 24 is provided with a fixing groove 243. The protrusion 222 is stuck in the fixing groove 243. At this time, the filter cartridge mounting seat 221 is located in the cavity 241, which makes it easier to assemble the filter cartridge sleeve 24 and can also prevent the cavity 241 from being misaligned with the opening 11.

[0036] Further, such as Figure 3 , Figure 6 and Figure 7 As shown, the filter element assembly 2 further includes a support seat 25, which is installed above the filter element sleeve 24. The support seat 25 is provided with a through hole 251, and the position of the through hole 251 corresponds to the position of the opening 11, so that the filter element 21 can pass through the through hole 251 and enter the cavity 241 after being inserted into the opening 11. It should be noted that the support seat 25 can be integrated with the filter element sleeve 24, or can be separated.

[0037] Specifically, in this embodiment, a buckle 252 is provided on the support seat 25, and a flat plate 244 is provided outside the filter cartridge sleeve 24. The buckle 252 is buckled on the edge of the flat plate 24, so that the support seat 25 is more firmly installed on the filter cartridge sleeve 24.

It can be understood that when the cover 3 is covered, the second protrusion 31 is aligned with the position of the second limiting groove 2511. At this time, the cover 3 is stuck on the support seat 25, which can prevent the cover 3 from falling during transportation. When the filter element needs to be replaced, the cover 3 is disassembled upward, and the second protrusion 31 slides out of the second limiting groove 2511.

[0039] Specifically, the through hole 251 is provided with a cylindrical ring 2512 extending outward toward the filter sleeve 24, and the side wall of the cavity 24 is provided with a boss 2411. When the cover 3 is closed on the opening 11, the ring 2512 is located on the boss 2411, which can further limit the cover 3.

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0041] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
