Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a cover assembly and a filter. Background Technology

[0002] Due to the presence of leftover food, fish waste, algae, and other factors, the water in aquariums can gradually become cloudy if no water quality intervention is performed over a long period, affecting the survival and visual appeal of the fish. Therefore, the common practice is to install a filter in the aquarium. The filter circulates and filters the water to remove cloudy impurities, ensuring that the water quality in the aquarium remains good.

[0003] However, for filters, the water pump is often fixed to the outlet pipe to prevent leakage. The common practice is to make the outlet pipe and the water pump into an integrated module. However, when the water pump needs to be replaced, the large module needs to be removed, which is inconvenient for disassembly and assembly and has very low convenience. Utility Model Content

In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0040] like Figure 1 and Figure 2 As shown, a preferred embodiment of this utility model discloses a filter and its cover assembly 10. The filter includes a cover assembly 10, a filter housing 20, and a filter assembly 30. The filter housing 20 has an installation cavity 21, and the filter assembly 30 is disposed in the installation cavity 21. The filter housing 20 has an inlet pipe 22 and an outlet pipe 23 communicating with the installation cavity 21, forming a water flow channel between the inlet pipe 22 and the outlet pipe 23. The outlet pipe 23 is located on the side wall of the filter housing 20. Figures 3 to 5 The cover assembly 10 includes a cover 11 and a water pump 12. The water pump 12 is installed at the bottom of the cover 11, and its projection area is located within the projection area of ​​the cover 11 along the axial direction of the cover 11. The water pump 12 can be fixed to the bottom of the cover 11 by snap-fit, fastener connection, or other means. The top of the filter box 20 forms an installation port 24, and the cover 11 is detachably installed in the installation port 24. The water pump 12 extends into the installation cavity 21, and its inlet 122 communicates with the installation cavity 21. The inlet 122 of the water pump 12 can be located on the side wall or bottom of the water pump 12. The outlet 123 of the water pump 12 is located on the side wall of the water pump 12 and communicates with the outlet pipe 23. Figure 6 and Figure 7 The filter assembly 30 is located in the water flow channel formed between the water inlet 122 of the water pump 12 and the water inlet pipe 22. The water inlet pipe 22 and the water outlet pipe 23 extend into the water body of the fish tank. As the water pump 12 works, the water in the fish tank flows from the water inlet pipe 22 into the water flow channel in the filter box 20, and then enters the water inlet 122 of the water pump 12 after being filtered by the filter assembly 30. Finally, it flows back into the fish tank from the water outlet 123 of the water pump 12 into the water outlet pipe 23.

[0041] In some embodiments, the outlet pipe 23 can be directly inserted into and fixed to the side wall of the filter housing 20 to communicate with the outlet 123 of the water pump 12. Figures 8 to 11 In some embodiments illustrated, the outlet pipe 23 can also be fixed to the filter box 20 via a connecting pipe 232. The first end of the connecting pipe 232 is located inside the mounting cavity 21, and the first end of the connecting pipe 232 is provided with a sealing sleeve 231. The sealing sleeve 231 is fitted onto the pipe wall of the first end of the connecting pipe 232 without blocking the pipe opening at the first end. The outlet 123 of the water pump 12 abuts against the sealing sleeve 231, and the outlet 123 of the water pump 12 is connected to the pipe opening at the first end of the connecting pipe 232. The second end of the connecting pipe 232 extends out of the filter box 20 and is fixedly connected to the outlet pipe 23. The second end of the connecting pipe 232 is connected to the outlet pipe 23, which can improve the stability and airtightness of the pipe installation and prevent water leakage. Furthermore, both the cover 11 and the water pump 12 are cylindrical. The first end of the connecting pipe 232 forms a beveled surface 2321 that matches the side wall of the water pump 12. The sealing sleeve 231 has a water passage hole 2311 in the middle. The end shape of the sealing sleeve 231 matches the beveled surface 2321, which not only avoids hindering the rotation and removal of the cover 11, but also improves the adaptability of the structure and prevents water leakage. Furthermore, the second end of the connecting pipe 232 is provided with a thread 2323. A screw cap 233 with an internal thread is fitted onto the water outlet pipe 23. The screw cap 233 is fitted onto the water outlet pipe 23 and can move relative to the water outlet pipe 23. The screw cap 233 is screwed into the second end of the connecting pipe 232 by means of a threaded connection to fix the water outlet pipe 23 and the connecting pipe 232 together. A sealing ring can be provided in the screw cap 233 to seal the connection gap between the connecting pipe 232 and the water outlet pipe 23 to prevent water leakage. In other embodiments, the first end of the water outlet pipe 23 extends into the mounting cavity 21, and the first end of the water outlet pipe 23 is directly fitted with a sealing sleeve 231. The sealing sleeve 231 is fitted onto the pipe wall of the first end of the water outlet pipe 23, and the water outlet 123 of the water pump 12 abuts against the sealing sleeve 231, which can also improve the airtightness of the pipe and prevent water leakage.

[0042] An annular boss 121 is provided at the outlet 123 of the water pump 12. The annular boss 121 is a closed annular structure, surrounding the outlet 123 of the water pump 12. The top of the annular boss 121 abuts against the sealing sleeve 231, so that the outlet 123 of the water pump 12 is directly opposite the water passage hole 2311 of the sealing sleeve 231, and is also connected to the water outlet pipe 23, thereby further preventing water leakage. An auxiliary positioning structure can be provided between the cover 11 and the mounting port 24 so that after the cover 11 is fully installed on the mounting port 24, the outlet 123 of the water pump 12 is directly facing and abutting against the sealing sleeve 231.

[0043] The filter housing 20 has a through-hole 27 on its side wall. The water outlet pipe 23 is directly or indirectly fixed to the through-hole 27 via the connecting pipe 232. Furthermore, the outer wall of the connecting pipe 232 is provided with a retaining ring 2322. The radial dimension of the retaining ring 2322 is larger than that of the through-hole 27. One end of the connecting pipe 232 passes through the through-hole 27 from the inside of the mounting cavity 21. The retaining ring 2322 stops against the inner wall of the mounting cavity 21 to limit the movement and prevent the connecting pipe 232 from coming out of the through-hole 27. The first end of the connecting pipe 232 extending out of the through-hole 27 is fixedly connected to the water outlet pipe 23. In one embodiment, the end of the sealing sleeve 231 away from the water pump 12 abuts against the retaining ring 2322. Furthermore, the retaining ring 2322 is provided with an axially extending locking protrusion on the side near the sealing sleeve 231, and the sealing sleeve 231 is provided with an axially extending locking groove. During installation, the sealing sleeve 231 is inserted into the locking protrusion through the locking groove to achieve quick positioning and assembly, and can prevent the sealing sleeve 231 from rotating relative to the connecting pipe 232.

[0044] See again Figures 2 to 5 The cover 11 has a locking block 111 on its side wall, and the wall of the mounting port 24 has a screw hole 241. The cover 11 is screwed into the screw hole 241 by the locking block 111 to be installed at the mounting port 24. The water inlet 122 of the water pump 12 is directly opposite the filter assembly 30. In the axial direction of the cover 11, the filter assembly 30 is directly opposite the mounting port 24, and the projection area of ​​the filter assembly 30 is located within the projection area of ​​the mounting port 24. Specifically, the top of the filter housing 20 is provided with a cover plate 26, which covers the mounting cavity 21. The mounting opening 24 is opened on the cover plate 26. The cover body 11 is detachably installed on the mounting opening 24, and a sealing ring 124 is fitted on the water pump 12. When the cover body 11 is screwed into the opening 241 by the locking block 111, the sealing ring 124 is tightly clamped between the water pump 12 and the cover plate 26, so that the cover body assembly 10 is sealed and fixed on the cover plate 26 to prevent water leakage. The locking block 111 cannot be rotated further after it is screwed to the end of the opening 241. The screw opening 241 on the mounting port 24 extends to the edge of the mounting port 24 to form an opening. The locking block 111 can be screwed into the guide screw opening 241 through this opening and rotated along the screw opening 241. Furthermore, the opening section of the screw opening 241 is an inclined slide groove structure, and the end is a horizontal slide groove structure. The locking block 111 is screwed into the horizontal slide groove structure through the inclined slide groove structure and will be pressed and fixed by the horizontal slide groove structure.

[0045] See again Figure 6 and Figure 7The filter assembly 30 includes a first filter assembly 31 and a second filter assembly 32, which are arranged sequentially along the water flow channel. The second filter assembly 32 is located directly below the mounting port 24. The maximum radial width of the second filter assembly 32 is less than or equal to the radial dimension of the mounting port 24. That is, the projection area of ​​the second filter assembly 32 along the axial direction of the cover 11 is located within the projection area of ​​the mounting port 24, allowing the second filter assembly 32 to be pulled out from the mounting port 24. (See also...) Figure 3 A handle 112 is provided on the top of the cover 11 for convenient operation such as turning or pulling out the cover 11. (See also...) Figure 4 The bottom of the water pump 12 is the water inlet 122, which can draw water filtered by the second filter component 32 and discharge the water from the outlet 123, and then discharge it back into the fish tank through the outlet pipe.

[0046] See again Figure 1 In this specific embodiment, the inlet pipe 22 is also located on the side wall of the filter housing 20, which helps to reduce the overall size of the filter. A wall-mounting bracket 25 is provided on the side wall of the filter housing 20, and the inlet pipe 22 and the outlet pipe 23 are respectively located on the wall-mounting bracket 25, which allows the entire filter to be hung on the outside of the aquarium glass wall, while the inlet pipe 22 and the outlet pipe 23 are located inside the aquarium to realize water inlet and outlet.

[0047] The cover assembly 10 disclosed in the preferred embodiment of this utility model integrates the water pump 12 below the cover 11, and can be removed together with the cover 11. The cover 11 can be a screw cap with a rotational installation method, or a cover with a vertical snap or other fixing method. When the cover assembly 10 is installed on the filter box 20 of the filter, the outlet 123 of the water pump 12 can be restricted by the rotation limiting structure to just abut against the water outlet pipe 23 provided on the filter box 20, and a sealing sleeve 231 is provided between the water outlet pipe 23 and the outlet 123 of the water pump 12, so that the water outlet 123 of the water pump can be transmitted through the water outlet pipe 23 without leakage. The water outlet pipe 23 does not need to be integrated with the water pump 12 on the same module, thereby achieving the effect of convenient disassembly and assembly. Furthermore, after the cover 11 is turned or pulled out from the mounting port 24, the filter assembly 30 in the corresponding filter box 20 below it can also be pulled out from the mounting port 24 for replacement. This setting makes it very convenient to inspect and replace the water pump 12 and the filter assembly 30 below.
