Description

Technical Field

[0001] The utility model relates to the technical field of aquarium products, in particular to a filtering device used in an aquarium. Background Art

[0002] Aquariums are glass vessels used to raise aquatic organisms for viewing. Currently, aquariums on the market are generally equipped with filters. The function of the filter is to filter out particulate matter (fish excrement, fish secretions, leftover bait) and other waste in the water through filter elements (filter cotton, filter nets), so as to adjust various water indicators and maintain the stability of the water quality in the aquarium. The filter element needs to be replaced and cleaned frequently. If it is not replaced in time, the filter element may be blocked, making it impossible for water to flow through the filter element, thus causing the water pump to burn out, affecting the health of the organisms in the aquarium.

DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0026] In the embodiment, Figure 1 , Figure 2 , Figure 3 As shown, the filtering device for an aquarium comprises a housing, a water inlet pipe and a water outlet pipe connected to the housing, and further comprises:

[0027] A filter chamber 1 is arranged in the box;

[0028] The sedimentation bin 2 is arranged below the No. 1 filtering bin 1; the top surface of the sedimentation bin 2 is provided with a No. 1 water hole 3 for communicating with the No. 1 filtering bin 1, and the bottom is provided with a sewage pipe 4;

[0029] The filter cylinder 5 is arranged in the first filter chamber 1, the water inlet of the filter cylinder 5 is connected to the water inlet pipe, and the water outlet is connected to the sedimentation chamber 2;

[0030] The second filter chamber 6 is arranged at the side of the first filter chamber 1 and is connected with the first filter chamber 1 . The second filter chamber 6 is installed with a filter box 7 .

[0031] After the water with particulate matter enters the filter cylinder 5, the water can overflow from the circumference of the filter cylinder 5, and the particulate matter is transported to the sedimentation bin 2 for sedimentation, and the particulate matter is discharged through the sewage pipe 4. The No. 1 water hole 3 is used to connect the No. 1 filter bin 1 with the sedimentation bin 2 to facilitate the backflow of water. The filter box 7 is installed with a filter element. The water in the No. 1 filter bin 1 enters the No. 2 filter bin 6 and is filtered by the filter box 7 and then flows back to the aquarium. This structure does not require a filter element to filter the particulate matter, which increases the service life of the filter element and can effectively reduce the number of times the filter element is replaced.

[0032] In the embodiment, Figure 1 , Figure 2 As shown, the first water hole 3 is installed with a joint 8, and the water outlet of the joint 8 is located on the side of the joint 8. When the water in the filter chamber 2 is full, part of the water flows into the first filter chamber 1 from the joint 8, and the inner wall at the top of the joint 8 can play a certain blocking role on floating objects in the water.

[0033] In the embodiment, Figure 1 , Figure 2 As shown, the top surface of the sedimentation bin 2 is also provided with a No. 2 water hole 9 for communicating with the No. 1 filtering bin 1, and the No. 2 water hole 9 is installed with a pressure relief valve 10. When the water pressure in the sedimentation bin 2 increases, the water acts on the pressure relief valve 10, allowing the pressure relief valve 10 to open the No. 2 water hole 9 to relieve the pressure of the sedimentation bin 2.

[0034] In the embodiment, Figure 1 , Figure 2As shown, a guide plate 11 is provided in the sedimentation bin 2, and a dirt collecting frame 12 for communicating with the sewage pipe 4 is provided at the bottom of the sedimentation bin 2, and the upper end of the guide plate 11 corresponds to the water outlet of the filter cylinder 5, and the lower end corresponds to the dirt collecting frame 12. Particulate matter can enter the dirt collecting frame 12 along the guide plate 11 to precipitate, and then be discharged through the sewage pipe 4, ensuring that no sediment is accumulated in the sedimentation bin 2.

[0035] In the embodiment, Figure 2 , Figure 6 As shown, the bottom surface of the dirt collecting frame 12 gradually becomes lower towards the direction close to the sewage discharge pipe 4, and inclined surfaces 13 connected to the bottom surface of the dirt collecting frame 12 are provided on both sides of the dirt collecting frame 12. It is convenient for the sewage discharge pipe 4 to discharge the sediment in the dirt collecting frame 12.

[0036] In the embodiment, Figure 3 , Figure 5 As shown, a shower plate 18 is provided on the top surface of the No. 2 filter bin 6, and a No. 1 gap 14 is provided between the two sides of the shower plate 18 and the side wall of the No. 2 filter bin 6, and the shower plate 18 is provided with a water inlet 15, and the water inlet 15 is lower than the connection point between the No. 1 filter bin 1 and the No. 2 filter bin 6. The shower plate 18 is evenly distributed with water outlet holes, which can evenly drip the water into the filter box 7. When the shower plate 18 is blocked, the water can flow from the connection point between the No. 1 filter bin 1 and the No. 2 filter bin 6 into the No. 2 filter bin 6, which plays an overflow role and prevents the water pump from drying out or the water from overflowing the box.

[0037] In the embodiment, Figure 3 , Figure 4 As shown, a second gap 16 is provided between the filter box 7 and the second filter chamber 6, and the filter box 7 is provided with an overflow port 17 corresponding to the second gap 16. The filter box 7 is a drawer-type filter box. When the filter element in the filter box 7 is blocked, the water flows out from the overflow port 17 and flows into the bottom of the second filter chamber 6 through the second gap 16 to prevent the water pump from drying out.

[0038] Obviously, the above embodiments of the present invention are merely examples for illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to provide all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still fall within the scope of protection of the present invention.
