Description

Technical Field

[0001] This utility model relates to the field of aquarium technology, and in particular to a wall-mounted filter and an aquarium. Background Technology

[0002] An aquarium is a container specifically designed for the observation and keeping of aquatic plants and animals. As an animal enclosure, it typically has at least one side made of transparent glass or high-strength plastic for easy viewing. A filter is usually suspended on the outer wall of the aquarium, and a water pump, along with inlet and outlet pipes, circulates water within the aquarium. Externally mounted filters reduce the space occupied within the aquarium and are therefore very popular.

[0003] Currently, to avoid the water pump impeller height being higher than the water level in the aquarium, causing it to run dry during startup, the water pump is usually installed on the inlet pipe and below the water level in the aquarium. However, to ensure the connection strength between the water pump and the inlet pipe, hooks are usually installed on the pump casing for reinforcement, resulting in a complex structure, inconvenient installation, and low installation stability. Utility Model Content

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] like Figures 1 to 7As shown, a wall-mounted filter of this embodiment includes a main housing 1, a filter element, a water pump 2, and a first water pipe 3. A filter chamber 10 and a pump chamber 11 are spaced apart within the main housing 1. The filter element is placed within the filter chamber 10. A first mounting port 12 is provided through the top wall of the pump chamber 11 in a vertical direction (vertical direction is the Z direction shown in the figure), and a second mounting port 13 is provided through the bottom wall of the pump chamber 11. The cross-sectional dimension of the second mounting port 13 is smaller than the cross-sectional dimension of the pump chamber 11 (the cross-sectional dimension refers to the cross-sectional dimension along the X direction), so that the second mounting port 13... The connection between the cavity wall and the cavity wall of the pump cavity 11 forms a first support surface 14. The outer peripheral wall of the water pump 2 is provided with a second support surface 21. The water pump 2 is inserted into the pump cavity 11 along the first mounting port 12. The second support surface 21 abuts against the first support surface 14. Part of the water pump 2 passes through the second mounting port 13 and protrudes from the pump cavity 11. One end of the water pump 2 protruding from the pump cavity 11 is connected to a first water pipe 3. The end of the first water pipe 3 away from the water pump 2 is connected to an external water source. The water pump 2 is connected to the filter cavity 10. The main housing 1 is also provided with a return port 15 that communicates with the filter cavity 10. The return port 15 is connected to an external water source.

[0033] It is understood that in this wall-mounted filter, a first mounting port 12 is opened on the top wall of the pump chamber 11 of the main housing 1, allowing the water pump 2 to be vertically inserted into the pump chamber 11 through the first mounting port 12. The first support surface 14 abuts against the second support surface 21, ensuring the water pump 2 is stably installed within the pump chamber 11, effectively improving the ease of installation, making it convenient, quick, and providing high support stability. The second mounting port 13 allows part of the water pump 2 to protrude from the pump chamber 11, facilitating the installation of the first water pipe 3 and further improving the ease of installation of both the water pump 2 and the first water pipe 3.

[0034] Furthermore, the pump chamber 11 has a first central axis extending vertically. A first engaging portion 16 is provided on the wall of the pump chamber 11 around the first central axis. The top end face of the first engaging portion 16 is a first supporting surface 14. The first engaging portion 16 encloses and forms a second mounting port 13. The water pump 2 has a second central axis extending vertically. A second engaging portion is provided on the outer peripheral wall of the water pump 2 around the second central axis. The bottom end face of the second engaging portion is a second supporting surface 21. The second engaging portion abuts against the first engaging portion 16. The abutment between the second engaging portion and the first engaging portion 16 achieves support for the water pump 2 from the main housing 1. In this embodiment, the first engaging portion 16 is arranged around the first central axis, and the second engaging portion is arranged around the second central axis, ensuring the supporting effect of the first engaging portion 16 and the second engaging portion. Of course, in some embodiments, there may be multiple first snap-fit ​​portions 16, and multiple first snap-fit ​​portions 16 are arranged at intervals around the first central axis. Multiple second snap-fit ​​portions are arranged at intervals on the outer periphery of the water pump 2 relative to the positions of the first snap-fit ​​portions 16. No further limitations are made here.

[0035] Furthermore, the wall-mounted filter also includes a sealing sleeve 4, which is fitted onto the outer peripheral wall of the water pump 2, and at least partially clamped between the cavity wall of the pump chamber 11 and the outer peripheral wall of the water pump 2. The sealing sleeve 4 effectively enhances the sealing performance between the water pump 2 and the main housing 1. Of course, the water pump 2 achieves a sealed connection with the groove wall of the pump chamber 11 through the sealing sleeve 4. The sealing sleeve 4 acts as a buffer and anti-slip agent, reducing loosening caused by vibration or external forces and ensuring the stability of the equipment during long-term operation. In addition, the sealing sleeve 4 also has a certain shock absorption and buffering performance, effectively absorbing the vibration and noise generated during the operation of the water pump 2, reducing the impact on the aquarium and the surrounding environment, and improving the viewing experience.

[0036] In this embodiment, a first snap-fit ​​groove 41 is recessed on the outer peripheral wall of the sealing sleeve 4, and a first snap-fit ​​part 16 snaps into the first snap-fit ​​groove 41. The snap-fit ​​between the sealing sleeve 4 and the main housing 1 is achieved through the snap-fit ​​engagement of the first snap-fit ​​part 16 and the first snap-fit ​​groove 41, resulting in a simple structure and a stable connection. Of course, besides setting the first snap-fit ​​groove 41 on the outer peripheral wall of the sealing sleeve 4 and the first snap-fit ​​part 16 on the groove wall of the pump cavity 11, the first snap-fit ​​groove 41 can also be set on the groove wall of the pump cavity 11, and the first snap-fit ​​part 16 can be set on the outer peripheral wall of the sealing sleeve 4; no further limitations are imposed here.

[0037] Of course, the sealing sleeve 4 is also provided with a first inclined surface 42. The first inclined surface 42 connects the bottom end face of the sealing sleeve 4 and the outer peripheral wall of the sealing sleeve 4. The first inclined surface 42 is inclined from one end adjacent to the bottom end face of the sealing sleeve 4 toward the end away from the bottom end face of the sealing sleeve 4 and toward the direction away from the central axis of the sealing sleeve 4. When the sealing sleeve 4 moves downward in the vertical direction and is engaged with the first engaging part 16, the first engaging part 16 is slidably connected with the first inclined surface 42. By setting the first inclined surface 42, the sealing sleeve 4 is slidably guided when passing through the first engaging part 16, avoiding the bottom end face of the sealing sleeve 4 being blocked above the first engaging part 16 and preventing part of the sealing sleeve 4 from passing through the installation port.

[0038] Furthermore, the water pump 2 includes a housing 22 and a pump body 23. The pump body 23 is disposed inside the housing 22. The first water pipe 3 is connected to the housing 22. The housing 22 includes a first housing 221 and a second housing 222 that are detachably connected. The first housing 221 abuts against the top of the second housing 222. The outer peripheral wall of the first housing 221 is located outside the outer peripheral wall of the second housing 222. The bottom end face of the first housing 221 and the portion located on the outer peripheral wall of the second housing 222 is the second support surface 21. The sealing sleeve 4 is provided with a sealing channel 43 that extends vertically. The sealing channel 43 includes a first channel 431 and a second channel 432 that are connected. The cross-sectional dimension of the first channel 431 is larger than the cross-sectional dimension of the second channel 432, so as to form a third support surface 44 at the connection between the first channel 431 and the second channel 432. The outer peripheral wall of the first housing 221 abuts against the cavity wall of the first channel 431, and the second support surface 21 abuts against the third support surface 44. The second housing 222 abuts against the cavity wall of the second channel 432.

[0039] In other words, the detachable design of the first housing 221 and the second housing 222 improves the ease of installation and maintenance of the water pump 2. The sealing sleeve 4 effectively enhances the sealing performance between the first housing 221 and the second housing 222, reducing the possibility of leakage from the outer casing 22. The outer peripheral wall of the first housing 221 abuts against the cavity wall of the first channel 431, and the outer peripheral wall of the second housing 222 abuts against the cavity wall of the second channel 432, achieving a sealed connection between the sealing sleeve 4 and the first housing 221 and the second housing 222. The design of the first channel 431, and the abutment between the second support surface 21 and the third support surface 44, effectively improves the installation accuracy of the sealing sleeve 4, preventing incomplete or excessive sliding during installation and thus ensuring a tight seal. It also enhances the installation stability of the sealing sleeve 4 and reduces the possibility of it slipping off. The second support surface 21 abuts against the third support surface 44, and the sealing sleeve 4 is engaged with the first engaging portion 16. That is, the groove wall of the first engaging groove 41 of the sealing sleeve 4 is supported on the first support surface 14. Thus, the second support surface 21 is supported on the first support surface 14 by the sealing sleeve 4. In addition, the portion of the first housing 221 that protrudes outward from the second housing 222 in the horizontal direction is the second engaging portion (the horizontal direction is the X direction in the figure).

[0040] Furthermore, the inner wall of the first housing 221 is located between the outer peripheral wall and the inner wall of the second housing 222. The second housing 222 protrudes from the side facing the first housing 221 and has multiple first connecting portions 2221. These first connecting portions 2221 are spaced apart around the second central axis and are adjacent to the inner wall of the second housing 222. One side of the first housing 221 and the first connecting portions 2221 has a third engaging portion 2222, and the other side has a second engaging groove 2211. The third engaging portion 2222 engages within the second engaging groove 2211. For example, the third engaging portion 2222 is provided on the side of the first connecting portion 2221 facing away from the first central axis, and the second engaging groove 2211 is formed on the first housing 221, allowing the third engaging portion 2222 to engage within the second engaging groove 2211, thereby achieving a stable connection between the first housing 221 and the second housing 222. Of course, in addition to setting the third latching part 2222 on the first connecting part 2221 and setting the second latching slot 2211 on the first housing 221, the third latching part 2222 can also be set on the first housing 221 and the second latching slot 2211 can be set on the first connecting part 2221. No further limitations are made here.

[0041] In addition, an annular limiting groove is provided between the sealing sleeve 4 and the first connecting part 2221, and the first housing 221 is locked in the limiting groove, which effectively improves the installation stability between the sealing sleeve 4, the first housing 221 and the second housing 222.

[0042] Optionally, if the first housing 221 is located above the second housing 222, then the third snap-fit ​​portion 2222 is provided with a second inclined surface. The second inclined surface is inclined from the end away from the second housing 222 toward the end adjacent to the second housing 222 and toward the direction away from the second central axis. The first housing 221 can be slidably connected with the second inclined surface to improve the smoothness of the third snap-fit ​​portion 2222 when it snaps into the second snap-fit ​​groove 2211 and to prevent the first housing 221 from blocking the top of the third snap-fit ​​portion 2222.

[0043] Furthermore, at least two positioning parts 45 are spaced around the central axis on the cavity wall of the first channel 431. A positioning groove 2212 is formed on the bottom end face of the first housing 221 corresponding to the positioning part 45, and the positioning groove 2212 penetrates the inner side wall and outer peripheral wall of the first housing 221. The positioning part 45 can be inserted into the positioning groove 2212. Through the insertion and engagement of the positioning part 45 and the positioning groove 2212, the insertion accuracy of the first housing 221 and the connection stability between the first housing 221 and the sealing sleeve 4 can be effectively improved, reducing the possibility of shaking or loosening between the sealing sleeve 4 and the first housing 221.

[0044] Optionally, the positioning part 45 is disposed adjacent to the third support surface 44, and the positioning part 45 abuts against the side of the second housing 222 facing the first housing 221, which can effectively improve the installation stability of the second housing 222 and the sealing sleeve 4. Combined with the above-mentioned abutment between the second support surface 21 and the third support surface 44, that is, the third support surface 44 being flush with the top of the second housing 222, the first housing 221 simultaneously abutting against the third support surface 44 and the top of the second housing 222, and the positioning part 45 abutting against the top of the second housing 222, the stability of the connection between the sealing sleeve 4, the first housing 221, and the second housing 222 can be ensured.

[0045] Preferably, a fourth engaging part 46 is provided at the end of the positioning part 45 away from the cavity wall of the first channel 431. The fourth engaging part 46 and the cavity wall of the first channel 431 are spaced apart to form a third engaging groove 47. The first housing 221 is engaged in the third engaging groove 47, which can further enhance the connection stability between the first housing 221 and the sealing sleeve 4.

[0046] In summary, the installation sequence and connection relationship of the sealing sleeve 4, the first housing 221, and the second housing 222 include: placing the sealing sleeve 4 around the outer periphery of the first housing 221 and making the positioning part 45 abut against the top of the second housing 222, so that the third support surface 44 is flush with the top end face of the second housing 222; inserting the first housing 221 vertically into the third snap-fit ​​groove 47 until the first housing 221 is flush with the third support surface 44 and the top of the second housing 222; at this time, the first housing 221 is snapped into the limiting groove formed by the first connecting part 2221 and the sealing sleeve 4, and the third snap-fit ​​part 2222 is snapped into the second snap-fit ​​groove 2211; the positioning part 45 is inserted into the positioning groove 2212, and the rings are interlocked, effectively ensuring the connection stability of the sealing sleeve 4, the first housing 221, and the second housing 222.

[0047] In addition, in this embodiment, when the water pump 2 is installed, the sealing sleeve 4 is also engaged between the groove wall of the pump chamber 11 and the outer peripheral wall of the first housing 221, and is also engaged between the first engaging part 16 and the bottom end face of the first housing 221 in the vertical direction, effectively ensuring the installation stability of the main housing 1, the sealing sleeve 4 and the outer shell 22 of the water pump 2.

[0048] In some embodiments, the wall-mounted filter further includes an outlet pipe 5. The main housing 1 includes a second connecting portion and a first housing 17 and a second housing 18 spaced apart along a first direction. The first housing 17 is connected to the second housing 18 through the second connecting portion. The first housing 17 and the second housing 18 are spaced apart to form a clamping groove 19 for mounting an aquarium. The second housing 18 is located inside the aquarium. A filter chamber 10 is provided inside the first housing 17, and a pump chamber 11 is provided inside the second housing 18. The first water pipe 3 includes an inlet pipe connected to the bottom of the water pump 2 and extending vertically. The water pump 2 communicates with the filter chamber 10 through the outlet pipe 5. The first direction is angled to the vertical direction. The main housing 1 has a simple structure. The spaced first housing 17 and the second housing 18 not only separate the filter chamber 10 from the pump chamber 11 but also form a clamping groove 19 for mounting the wall-mounted filter. In this embodiment, the main housing 1 also includes a cover, which is used to cover the top of the first housing 17 and the second housing 18 when the tops of the first housing 17 and the second housing 18 are open.

[0049] The installation process of the water pump 2 and the wall-mounted filter being hung as a whole in the aquarium includes: putting the sealing sleeve 4 on the water pump 2, inserting the water pump 2 vertically into the pump chamber 11, and making the first snap-fit ​​part 16 snap into the first snap-fit ​​groove 41 of the sealing sleeve 4. At this time, the water pump 2 is partially exposed at the installation port, the water inlet pipe is located at the bottom of the water pump 2, and the top of the water pump 2 is connected to the filter chamber 10 through the water outlet pipe 5. Then, the wall-mounted filter is hung as a whole on the edge of the aquarium, so that the edge is snapped into the clamping groove 19. At this time, the first box 17 is located outside the aquarium, the second box 18 is located inside the aquarium, and the water inlet pipe extends to below the water level of the aquarium. It should be noted that the impeller of the pump body 23 should also be located below the water level. When the pump body 23 is started, the water in the aquarium is pumped into the outer casing 22 through the inlet pipe, and flows to the filter chamber 10 through the outlet pipe 5. After being filtered by the filter element, it flows back to the aquarium through the return port 15, thus realizing the installation and use of the wall-mounted filter.

[0050] It is worth noting that the connection between the first water pipe 3 and the outer casing 22 is the first connection port, and the connection between the water outlet pipe 5 and the outer casing 22 is the second connection port. Furthermore, the rotation axis of the pump body 23 is aligned with the central axis of the first connection port and the central axis of the second connection port to ensure the pumping efficiency of the pump body 23.

[0051] An embodiment of this utility model also provides an aquarium, including the aquarium and a wall-mounted filter as described in any of the above embodiments. The wall-mounted filter is hung on the aquarium, and the first water pipe 3 of the wall-mounted filter is inserted into the aquarium. The return port 15 of the main housing 1 of the wall-mounted filter communicates with the aquarium. The wall-mounted filter of this aquarium has a first mounting port 12 on the top wall of the pump chamber 11 of the main housing 1. The water pump 2 can be vertically inserted into the pump chamber 11 through the first mounting port 12, and the first support surface 14 abuts against the second support surface 21, allowing the water pump 2 to be stably installed in the pump chamber 11.
