Description

Technical Field

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

[0002] Due to the presence of leftover food, fish feces, algae, and other factors, the water in an aquarium will gradually become cloudy if no intervention is made to improve water quality over a long period, affecting the survival of the fish and their visual appeal. In particular, oily or low-density debris will float on the surface of the water and is difficult to be sucked up by the filter inlet pipe located below the water level. This causes floating debris to continuously cover the upper layer of the water, hindering the fish's breathing and continuously polluting the water in the aquarium.

[0003] While conventional filters have an oil film extractor on the inlet pipe to remove oil film and other contaminants from the water surface, the inlet flow rate cannot be controlled. Once the floating contaminants on the water surface are removed, the inlet channel of the oil film extractor at the water surface will affect the normal inlet flow rate of the inlet pipe below the water surface, causing the filter to be unable to effectively extract and filter the water below the water surface. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model proposes an inlet pipe and filter for a filter, which can continuously and effectively extract and filter water below the water surface.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] In a first aspect, this utility model discloses an inlet pipe for a filter, comprising a float, an inlet pipe assembly, and a rotating sleeve coaxially arranged. The inlet pipe assembly has an inlet. The float is slidably sleeved around the periphery of the inlet pipe assembly along the axial direction. The rotating sleeve is rotatably connected to the inlet pipe assembly. The rotating sleeve includes a bottom wall, a rotating outer wall, and a baffle plate connected together. The rotating outer wall and the baffle plate are radially spaced apart. The inner wall surface of the baffle plate abuts against the outer wall surface of the inlet pipe assembly. The inner wall surface of the float and the outer wall surface of the inlet pipe assembly are radially spaced to form an oil film inlet channel. The oil film inlet channel communicates with the space between the rotating outer wall and the baffle plate. The inlet pipe assembly has an outlet corresponding to the baffle plate, and the outlet communicates with the pipe inside the inlet pipe assembly. The baffle plate can block or avoid the outlet as the rotating outer wall rotates, thereby controlling the communication area between the oil film inlet channel and the pipe inside the inlet pipe assembly.

[0007] Preferably, the water inlet pipe assembly includes an inlet pipe and a through pipe, with the through pipe sleeved over the outlet of the inlet pipe.

[0008] Preferably, the water inlet pipe assembly further includes a silicone sleeve, the outer wall of the water inlet pipe is provided with a limiting block, the silicone sleeve is fitted at the water inlet of the water pipe, and the first end of the silicone sleeve abuts against one end of the rotating sleeve, the silicone sleeve is also fitted on the water inlet pipe and the second end of the silicone sleeve abuts against the limiting block.

[0009] Preferably, the baffle is disposed at the inner edge of the bottom wall, and the baffle is a non-circular closed structure, and the water outlet corresponds to the height position of the baffle at the height position of the water inlet pipe assembly.

[0010] Preferably, the water baffle includes at least two sub-water baffles with an arc-shaped structure, the sub-water baffles extending upward from the bottom wall, and multiple sub-water baffles spaced apart along the circumferential direction at the inner edge of the bottom wall, with the inner wall surface of each sub-water baffle abutting the outer wall surface of the water inlet pipe assembly.

[0011] Preferably, the water outlet includes at least two sub-water outlets, each of which is distributed circumferentially along the water inlet pipe assembly. The height position of the sub-water outlets corresponds to the height position of the sub-baffle plate at the water inlet pipe assembly, and the size of each sub-water outlet is smaller than the size of the sub-baffle plate.

[0012] Preferably, the bottom end of the float is located between the rotating outer wall and the baffle plate.

[0013] Preferably, the outer wall of the water inlet pipe assembly is provided with a circumferentially extending rotating groove, and the inner wall of the rotating sleeve is provided with a buckle, which is engaged in the rotating groove and can rotate along the extending direction of the rotating groove.

[0014] Preferably, the inner edge of the bottom wall abuts against the outer wall of the water inlet pipe assembly.

[0015] Secondly, this utility model discloses a filter, including a filter box, a filter assembly, an outlet pipe and the inlet pipe mentioned in the first aspect, wherein the outlet of the inlet pipe assembly and the outlet pipe are respectively connected to the filter box, and the filter assembly is disposed in the flow channel between the inlet pipe and the outlet pipe in the filter box.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The water inlet pipe and filter disclosed in this utility model are designed with the float rod, water inlet pipe assembly and rotating sleeve coaxially, which realizes the compression of the volume of the water inlet pipe and eliminates the need for an additional oil film pipe; the total water inlet volume of the water inlet pipe is composed of the sum of the water inlet volume of the oil film water inlet channel and the water inlet of the water inlet assembly. The rotation adjustment structure of the rotating sleeve relative to the water inlet assembly can adjust the water inlet volume of the oil film water inlet channel into the water inlet assembly according to user needs, thereby indirectly controlling the water inlet volume of the water inlet of the water inlet assembly below the water surface. The structure is simple and the operation is convenient; for example, if the water inlet volume of the oil film water inlet with the opening at the water surface decreases, the water inlet volume of the water inlet of the water inlet assembly with the opening below the water body will increase, thereby enabling continuous and effective extraction and filtration of water below the water surface.

[0017] In a further embodiment, this utility model also has the following beneficial effects:

[0018] (1) The water inlet pipe assembly includes a water inlet pipe and a water passage pipe sleeved on the water inlet pipe. A silicone sleeve is provided between the water inlet pipe and the water passage pipe. The silicone sleeve is pressed between the rotating sleeve and the limiting block of the water inlet pipe, which can prevent the water inlet pipe from easily detaching from the water passage pipe and avoid structural loosening.

[0019] (2) A rotating groove is provided on the outer wall of the water inlet pipe assembly, and a buckle is provided on the inner wall of the rotating sleeve, so that the rotating sleeve only rotates relative to the water inlet pipe assembly and does not move along the axial direction, thus avoiding structural loosening.

[0020] (3) The inner edge of the bottom wall abuts against the outer wall of the water inlet pipe assembly, which can prevent water flow between the bottom wall and the water inlet pipe assembly, so that water can only enter the interior of the water inlet pipe assembly from the water inlet and the oil film water inlet channel.

[0035] The embodiments of this utility model are described in detail below. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of this utility model.

They are only for the convenience of describing the embodiments of this utility model and simplifying the description, 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.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0039] like Figure 1 As shown, Embodiment 1 of this utility model discloses a filter inlet pipe 100, including a float 10, an inlet pipe assembly 20, and a rotating sleeve 30 coaxially arranged. The inlet pipe assembly 20 has an inlet 201. The float 10 is slidably sleeved on the periphery of the inlet pipe assembly 20 along the axial direction. The rotating sleeve 30 is rotatably connected to the inlet pipe assembly 20. Figure 2 and Figure 3 The rotating sleeve 30 has a U-shaped structure, including a connected bottom wall 31, a rotating outer wall 32, and a baffle plate 33. The rotating outer wall 32 and the baffle plate 33 are radially spaced. The inner wall surface of the baffle plate 33 abuts against the outer wall surface of the inlet pipe assembly 20. The inner wall surface of the float 10 and the outer wall surface of the inlet pipe assembly 20 are radially spaced to form an oil film water inlet channel 40. The oil film water inlet channel 40 communicates with the space 35 between the rotating outer wall 32 and the baffle plate 33. Figure 4 and Figure 5 The water inlet pipe assembly 20 has a water outlet 202 at the position corresponding to the water baffle 33. The water outlet 202 is connected to the pipe inside the water inlet pipe assembly 20. The water baffle 33 can block or avoid the water outlet 202 as the outer wall 32 rotates, so as to control the connection area between the oil film water inlet channel 40 and the pipe inside the water inlet pipe assembly 20.

[0040] Combination Figure 6 In this embodiment, the water inlet pipe assembly 20 includes an inlet pipe 21 and a through pipe 22, with the lower end opening of the through pipe 22 fitted onto the outlet of the inlet pipe 21. Further, the water inlet pipe assembly also includes a silicone sleeve 23 disposed between the inlet pipe 21 and the through pipe 22. A limiting block 211 is provided on the outer wall of the inlet pipe 21. The silicone sleeve 23 is fitted onto the inlet (lower end opening) of the through pipe 22, with the upper end of the silicone sleeve 23 abutting against the lower end of the rotating sleeve 30. The silicone sleeve 23 is also fitted onto the inlet pipe 21, with its lower end abutting against the limiting block 211. The elastic force of the silicone sleeve 23 prevents the inlet pipe 21 from easily detaching from the through pipe 22. Specifically, the rotating sleeve 30 is fixed to the through pipe 22, while one end of the silicone sleeve 23 is fitted onto the outer wall of the rotating sleeve 30, and the other end is fitted onto the inlet pipe 21, thereby achieving elastic clamping and fixation between the two. In addition, the water inlet pipe 21 can also achieve a certain interference fit when it extends into the water outlet pipe 22, making it less likely to come out.

[0041] The baffle plate 33 is located at the inner edge of the bottom wall 31. The baffle plate 33 is not a closed annular structure around the water pipe 22, but rather a non-closed structure. Therefore, when the baffle plate 33 rotates relative to the water pipe 22, it does not continuously block the water outlet 202. Referring to the embodiment shown in the figure, the bottom wall 31 can be connected to the bottom end of the rotating outer wall 32 and the baffle plate 33. The inner wall of the baffle plate 33 abuts against the water pipe 22. The water outlet 202 is located on the water pipe 22 at a height corresponding to the baffle plate 33. Thus, when the rotating sleeve 30 rotates relative to the water pipe 22, the baffle plate 33 can gradually block or avoid the water outlet 202. The oil film inlet channel 40 can communicate with or close the water outlet 202 depending on the degree of blockage by the baffle plate 33 and the water outlet 202, thereby controlling the water inlet volume at the top of the float 10. Furthermore, the baffle plate 33 includes at least two arc-shaped sub-baffle plates, which extend upward from the bottom wall 31. Multiple sub-baffle plates are spaced apart along the circumferential direction at the inner edge of the bottom wall 31, with the inner wall surface of each sub-baffle plate abutting the outer wall surface of the inlet pipe assembly. Correspondingly, the water outlet 202 includes at least two sub-water outlets, which are spaced apart along the circumferential direction of the inlet pipe assembly. The height position of the sub-water outlets on the water outlet pipe 22 corresponds to the height position of the sub-baffle plates, and the size of each sub-water outlet is smaller than the size of the sub-baffle plates.

[0042] The bottom end of the float rod 10 is located between the rotating outer wall 32 and the baffle plate 33. When the bottom outer wall of the float rod 10 is blocked by the rotating outer wall 32, water flow is less likely to enter between the float rod 10 and the rotating sleeve 30, and can only enter from the top of the float rod 10 and the inlet 201 of the inlet pipe assembly 20. The float rod 10 has a hollow columnar structure, and the inner diameter of the float rod 10 is larger than the outer diameter of the baffle plate 33. This allows the bottom end of the float rod 10 to descend into the space 35 between the baffle plate 33 and the rotating outer wall 32, increasing the floating range of the float rod 10 and thus better adapting to the low water level of the aquarium. The rotating outer wall 32 has a ring structure, and the height of the rotating outer wall 32 is higher than the height of the baffle plate 33. The outer diameter of the float rod 10 is smaller than the inner diameter of the rotating outer wall 32. This allows the rotating outer wall 32 to surround the bottom end of the float rod 10 as much as possible, preventing water flow from entering the inlet 202 from the bottom end of the float rod 10. The inner diameter of the baffle plate 33 is larger than the outer diameter of the water pipe 22. Therefore, there is a radial gap between the float 10 and the water pipe 22. This gap is the oil film water inlet channel 40, which extends upward to the water inlet of the oil film water inlet channel 40. The oil film water inlet channel 40 is actually connected to the gap space 35 between the rotating outer wall 32 on the rotating sleeve 30 and the baffle plate 33.

[0043] In some embodiments, a circumferentially extending rotating groove 221 is provided on the outer wall of the water pipe 22, and a buckle 34 is provided on the inner wall of the rotating sleeve 30, specifically below the bottom wall 31. The buckle 34 engages with the rotating groove 221 and can rotate along the extending direction of the rotating groove 221 under a certain external force, allowing the rotating sleeve 30 to rotate relative to the water pipe 22. By providing the corresponding rotating groove 221 and buckle 34, the rotating sleeve 30 can rotate only relative to the water pipe 22 without moving axially.

[0044] In some embodiments, the inner edge of the bottom wall 31 abuts against the outer wall of the water inlet pipe 22, which can prevent water from flowing between the bottom wall 31 and the water inlet pipe 22, so that water can only enter the interior of the water inlet pipe assembly 20 from the water inlet 201 and the oil film water inlet channel 40.

[0045] The water inlet pipe 100 also includes a connecting pipe 50, which has a bent structure. One end of the connecting pipe 50 is connected to the outlet of the water inlet pipe assembly 20, and the other end is used to connect to the filter box of the filter.

[0046] In this embodiment, the float 10, acting as an oil film generator, is sleeved around the outer periphery of the water passage pipe 22, and the rotating sleeve 30 is also sleeved around the outer periphery of the water passage pipe 22. The top end of the float 10 (the top end of the oil film generator) and the water passage pipe 22 are radially spaced to form the inlet of the oil film inlet channel 40. By coaxially integrating the float 10 and the rotating sleeve 30 on the inlet pipe assembly 20, the water passage pipe 22 is connected to the filter housing of the filter, and the water flow therein enters the filter housing. The float 10 is buoyantly sleeved around the outer periphery of the water passage pipe 22, and the oil film inlet channel 40 of the float 10 extends into and is located within the rotating sleeve 30. The rotating sleeve 30 is equipped with a baffle plate 33. By rotating the angle between the rotating sleeve 30 and the water passage pipe 22, the blocking area of ​​the baffle plate 33 on the inlet 202 is adjusted, thereby adjusting the water flow rate from the oil film inlet channel 40 of the float 10 into the water passage pipe 22.

[0047] The coaxial structure design of the float 10, the water inlet pipe assembly 20, and the rotating sleeve 30 can greatly compress the volume of the overall water inlet pipe. At the same time, the water inlet ratio between the float 10 and the water inlet 201 of the water inlet pipe assembly 20 can be adjusted by rotating the rotating sleeve 30 on the outer periphery of the water inlet pipe assembly 20. The structure is simple and the operation is convenient.

[0048] like Figure 7As shown in the figure, Embodiment 2 of this utility model discloses a filter, including a filter housing 200, a filter assembly (not shown in the figure), a water outlet pipe 300, and the water inlet pipe 100 mentioned in Embodiment 1 above. The water outlet of the water inlet pipe assembly 20 and the water outlet pipe 300 are respectively connected to the filter housing 200. The filter assembly is disposed in the flow channel between the water inlet pipe 100 and the water outlet pipe 300 within the filter housing 200. The water outlet of the water inlet pipe assembly 20 is either the water outlet of the water pipe 22 or the water outlet of the connecting pipe 50.

[0049] The present invention discloses a filter with an inlet pipe 100 and a filter. The coaxial structure of the inlet pipe 100 reduces its volume, eliminating the need for a separate oil film pipe. The total water intake of the inlet pipe 100 is the sum of the water intake from the oil film inlet channel 40 and the inlet of the inlet pipe 21. The rotation adjustment structure of the rotating sleeve 30 relative to the water pipe 22 allows for adjustment of the water intake from the oil film inlet channel 40 into the water pipe 22 according to user needs, thereby indirectly controlling the water intake from the inlet pipe 21 below the water surface. The structure is simple and easy to operate. For example, if the water intake of the oil film inlet channel 40, which opens at the water surface, decreases, the water intake of the inlet pipe 21, which opens below the water body, increases, thus enabling continuous and effective extraction and filtration of water below the water surface.
