[0025] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0026] Combined with appendix Figures 1-8 A drawer-type filter box aquarium with dry and wet separation includes a water tank 1. The water tank 1 has a partition 2. One side of the water tank 1 is separated into a filter chamber by the partition 2. The filter chamber is equipped with a second partition 3, a guide plate 4, a limiting strip 5, and a third partition 7. A guide plate 4 is located on the upper part of one side of the second partition 3 in the filter chamber. The cavity on the side of the first partition 2 away from the guide plate 4 in the filter chamber is a water pump chamber 11. The upper part of the guide plate 4 is a water inlet guiding area. 12. Below the guide plate 4 is a dry-wet separation filtration area. Several drawer-type filter boxes 8 are slidably installed in the dry-wet separation filtration area. The dry-wet separation filtration area is provided with a limiting strip 5 to restrict the position of the drawer-type filter boxes. Filter cotton is placed in the drawer-type filter boxes 8. Below the dry-wet separation filtration area is a biochemical culture chamber 13. The biochemical culture chamber 13 is provided with a partition 7. The partition 7 divides the biochemical culture chamber 13 into a lower water chamber 131 and an upper water chamber 132.

[0027] The drawer-type filter box 8 has several drain holes 80. The bottom of the filter chamber near the water tank 1 has a water inlet 14 and a water outlet 15 on one side of the filter chamber. The water outlet 15 corresponds to the upper part of the upper water chamber 132. The water outlet uses an overflow method to discharge water, which can reduce water flow noise.

[0028] The water pump and water pipes are installed in the water pump compartment 11.

[0029] The water inlet 14 includes several vertical water inlet openings and one horizontal water inlet opening.

[0030] The filter chamber is covered with a light-shielding plate 16; the light-shielding is conducive to the reproduction of microorganisms such as digestive bacteria.

[0031] The guide plate 4 has several drain holes 40 and a water pipe support plate 41. The drain holes 40 allow the water to be filtered to flow relatively evenly onto the filter cotton of the drawer-type filter box 8, preventing local filter material accumulation from affecting the filtration efficiency. The top of the partition plate 2 and the top of the water pipe support plate 41 are provided with slots for supporting and fixing the water pipe.

[0032] The drawer-type filter box 8 is provided with a handle 81 on one side; the handle 81 makes it easy to pull out the drawer-type filter box 8 to replace the filter cotton.

[0033] The upper water chamber 132 of the biochemical culture chamber 13 is connected to the bottom of the lower water chamber 131. Biochemical filter media is placed in the lower water chamber 131 and the upper water chamber 132. The biochemical filter media is used to cultivate nitrifying bacteria in the aquarium.

[0034] The drawer-type filter box 8 has two layers. The drain holes 80 of the upper drawer-type filter box 8 are evenly arranged in the middle of the drawer-type filter box 8, and the drain holes 80 of the lower drawer-type filter box 8 are opened in the upper area corresponding to the drain compartment 131.

[0035] In this design, the drawer-type filter box 8 has two arrangement options. In the dry-wet separation filtration area, the opening for the drawer-type filter box 8 can be located on partition 2, allowing it to be pulled into the water tank 1. Alternatively, it can be located on the outer wall of the water tank 1, allowing it to be pulled out of the water tank 1. Both arrangements are very convenient. Pulling the drawer-type filter box 8 into the water tank 1 maintains the integrity of the water tank's exterior, making it suitable for users who prioritize the aquarium's aesthetics. Pulling the drawer-type filter box 8 out of the water tank 1 makes replacing the filter cotton in the drawer-type filter box 8 more convenient, suitable for users who prioritize practicality. Both specific setups achieve the effect of quickly replacing the filter cotton, making it very convenient to use.

[0036] When this device is in use, water in the water tank 1 is drawn from the inlet 14 by a water pump and pumped to the guide zone through the water pipe. The water flows through the drain hole 40 of the guide plate 4 onto the filter cotton in the drawer-type filter box 8 for filtration. The filtered water then flows through the drain hole 80 of the drawer-type filter box 8 onto the biochemical filter media in the biochemical culture chamber 13. The water flows through the lower chamber 131 and the upper chamber 132 in sequence and then flows back to the water tank 1 through the outlet 15. During this process, excrement and impurities in the water can be effectively filtered, while maintaining a stable content of microorganisms in the water tank.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
