[0002] With the increasing popularity of fishkeeping, more and more families are placing aquariums in their homes for enjoyment during their leisure time. The water quality in the aquarium affects both its aesthetic appeal and the health of the fish.

[0003] Existing aquarium filters often have large inlets, resulting in a small water flow per unit area. This makes them unable to provide sufficient suction to draw water from the aquarium, which can easily lead to the accumulation of a large amount of impurities at the bottom of the aquarium. This significantly degrades the water quality, affecting not only the aquarium's aesthetics but also the health of the fish. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model proposes a bottom suction accessory and a fish tank, which can increase the suction force at the water inlet and effectively increase the water flow speed at the water inlet, thereby effectively adsorbing fish feces and other impurities at the bottom of the fish tank.

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

[0006] In a first aspect, this utility model discloses a bottom suction accessory, including a bottom suction cover and a filter body. A flow channel is formed in the bottom suction cover, and the filter body is installed in the flow channel of the bottom suction cover. A water inlet and a water outlet are provided on the bottom suction cover. The water inlet is connected to one end of the flow channel, and the water outlet is connected to the other end of the flow channel. The bottom suction cover is also provided with mounting accessories.

[0007] Furthermore, the water inlet is located at the bottom of the bottom suction cover, and the opening direction of the water inlet is inclined downwards.

[0008] Furthermore, the water inlet extends along the bottom edge of the bottom suction cover.

[0009] Furthermore, the fitting includes at least two snap fasteners or elastic clips, which are disposed on the side of the bottom suction cover where the water outlet is located.

[0010] Furthermore, the inner wall of the bottom suction cover is provided with a guide plate, one edge of which faces the water inlet and the other edge of which faces the filter body.

[0011] Furthermore, the guide plate is located above the water inlet, the extension direction of the guide plate is towards the water inlet, and there are multiple guide plates, which are spaced apart from each other and arranged in parallel along the perpendicular direction of the extension direction.

[0012] Furthermore, the bottom suction cover includes a top wall, a bottom wall, a side wall, and a front wall. The top wall, bottom wall, and side wall are arranged to form an annular structure. The top wall and the side wall are respectively connected to the front wall. The bottom wall is spaced apart from the front wall to form the water inlet. The guide plate is connected to the inner wall surface of the front wall.

[0013] Furthermore, the inner wall surface of the front wall of the bottom suction cover is inclined relative to the bottom wall, the ends of each guide plate on the side away from the front wall are located on the same plane, and the filter body abuts against the end face of the guide plate on the side away from the front wall.

[0014] Furthermore, the bottom end of the guide plate is spaced apart from the bottom wall.

[0015] Secondly, this utility model discloses a fish tank, which is provided with a filter chamber and the bottom suction accessory described in the first aspect. The filter chamber is provided with a filter, and the wall of the filter chamber is provided with a water outlet.

[0021] (4) Multiple guide plates are arranged in parallel inside the bottom suction hood, which can divide the water channel and make the water flow to the filter body more uniform and controllable.

[0022] (5) The inner wall of the front wall of the bottom suction cover is inclined, which can guide the incoming water flow, so that the water flow can reach the higher position of the filter body more evenly, make full use of the filtration function of each area of ​​the filter body, and increase the service life of the filter body.

[0023] (6) The guide plate is spaced from the bottom wall of the bottom suction hood, which allows some slightly larger impurities to enter the larger space between the bottom end of the guide plate and the bottom wall, without easily blocking the water inlet and avoiding blockage problems.

[0024] Other beneficial effects of the embodiments of this utility model will be further described below. Attached Figure Description

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.

[0044] 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.

[0045] like Figures 1 to 5This utility model discloses a bottom suction accessory 10 and a fish tank 100 in a preferred embodiment. The fish tank 100 includes a tank body 30, a top cover 40, a filter chamber 20, and the bottom suction accessory 10. The filter chamber 20 is disposed inside the tank body 30 and contains a filter (not shown in the figure). The wall of the filter chamber 20 has a water passage, which is a water passage grille 21 as shown in the figure, or it can also be a perforated structure. Water in the tank body 30 enters the filter chamber 20 through the water passage grille 21 to reach the filter. The water inlet of the filter is close to and directly opposite the water passage grille 21. The bottom suction accessory 10 is installed at the water inlet of the water passage grille 21, so that the water inlet of the filter is directly opposite the bottom suction accessory 10. The bottom suction accessory 10 can reduce the cross-sectional area of ​​the water flow, which is beneficial to increasing the suction force of the water inlet 111 of the bottom suction accessory 10; and the assembly method is simple, and it can be directly applied to any fish tank with a water passage grille 21. Water flowing within the tank 30 passes through the bottom suction fitting 10 and then through the water grate 21, before entering the filter for filtration. The filtered water then returns to the tank 30. The filter chamber 20 can be located anywhere within the tank 30, such as the left or right side space, and is not limited to any particular location. Figure 2 The rear space of the cylinder body 30 shown. In addition to the grille structure, if the cylinder body 30 has a perforated structure, the shape of the mounting accessory 113 on the bottom suction cover 11 can be adapted to change. In this way, the bottom suction accessory 10 can also be directly installed on the perforated structure, for example, by snapping it onto the perforated structure. That is, the specific installation relationship can be a snap-fit ​​or other method that is easy to install and remove.

[0046] Combination Figure 6 The bottom suction accessory 10 includes a bottom suction cover 11 and a filter body 12. A flow channel is formed in the bottom suction cover 11, and the filter body 12 is installed in the flow channel of the bottom suction cover 11. The bottom suction cover 11 has an inlet 111 and an outlet 112. The inlet 111 is connected to one end of the flow channel, and the outlet 112 is connected to the other end of the flow channel. The bottom suction cover 11 is provided with a fitting 113 for mounting the bottom suction cover 11 at the inlet of the water-passing grid 21. The filter body 12 is, for example, a filter cotton, a filter screen, or other filter media. The filter body 12 can cover the cross-section of the flow channel, that is, the filter body 12 abuts against the four sides of the flow channel to ensure that the water entering through the inlet 111 can be filtered by the filter body 12.

[0047] In some embodiments, the water inlet 111 is located at the bottom of the bottom suction shroud 11, and the opening direction of the water inlet 111 is inclined downwards, specifically inclined downwards towards the side away from the water outlet 112; this facilitates the suction of impurities attached to the bottom of the cylinder 30. Further, refer to... Figure 3 and Figure 7 The water inlet 111 extends along the bottom edge of the bottom suction cover 11, which can increase the suction range.

[0048] refer to Figure 6 and Figure 9 The inner wall of the bottom suction shroud 11 is provided with a guide plate 114, with one edge of the guide plate 114 facing the water inlet 111 and the other edge facing the filter body 12. The guide plate 114 guides the water entering the bottom suction shroud 11, allowing the water flow to reach every area of ​​the filter body 12 more fully. Furthermore, the guide plate 114 is located above the water inlet 111, with its extension direction facing the water inlet 111. Multiple guide plates 114 are arranged parallel to each other and spaced apart along the perpendicular direction of their extension. The parallel arrangement of multiple guide plates 114 divides the water channel, making the water flow to the filter body 12 more uniform and controllable, and preventing large particles from being sucked into the filter body 12.

[0049] refer to Figure 10 The bottom suction hood 11 includes a top wall 1101, a bottom wall 1102, a side wall 1103, and a front wall 1104. The top wall 1101, bottom wall 1102, and side wall 1103 form a ring structure. The top wall 1101 and side wall 1103 are respectively connected to the front wall 1104. The bottom wall 1102 is spaced apart from the front wall 1104 to form a water inlet 111. A guide plate 114 is connected to the inner wall surface of the front wall 1104. The rear part of the bottom suction hood 11 is hollowed out to form a water outlet 112. Specifically, the guide plate 114 can be in the form of a triangular plate structure, with its front side connected to the front wall 1104, its bottom edge facing the water inlet 111, and its rear edge facing the water outlet 112. Further, combined with Figure 9 The inner wall surface of the front wall 1104 of the bottom suction cover 11 is inclined relative to the bottom wall 1102, and the bottom suction cover 11 has an overall structure that is thicker at the bottom and thinner at the top. The ends of each guide plate 114 on the side away from the front wall 1104 are located on the same plane, and the filter body 12 abuts against the end face of the guide plate 114 on the side away from the front wall 1104, so that the water guided by the guide plate 114 directly enters the filter body 12. By inclining the inner wall surface of the front wall 1104, the water flow entering the bottom suction cover 11 can be guided, so that the water flow can reach the higher position of the filter body 12 more evenly, making full use of the filtration function of each area of ​​the filter body 12 and increasing the service life of the filter body 12. The bottom end of the guide plate 114, i.e. the bottom edge, is spaced apart from the bottom wall 1102. By spacing the guide plate 114 from the bottom wall 1102, some slightly larger impurities can enter the larger space between the bottom end of the guide plate 114 and the bottom wall 1102, without easily blocking the inlet 111 and avoiding blockage problems.

[0050] refer to Figure 5 , Figure 6 and Figure 8In some embodiments, the mounting accessory 113 includes at least two snap-fit ​​elements or elastic clips, which are disposed on the side of the bottom suction cover 11 where the water outlet 112 is opened. The bottom suction accessory 10 can be secured to the water-passing grid 21 of the filter chamber 20 using the two snap-fit ​​elements or elastic clips. In one embodiment, the mounting accessory 113 is disposed on the side wall 1103, with mounting accessories 113 located on both the left and right side walls 1103, for example, each having a snap-fit ​​element or elastic clip. This allows the snap-fit ​​elements or elastic clips on both sides to extend into and secure the water outlet, thus firmly fixing the bottom suction accessory 10 to the water outlet.

[0051] The preferred embodiment of this utility model proposes a bottom suction accessory 10 and a fish tank 100. By adding a bottom suction accessory 10 with a smaller inlet diameter to the conventionally large-opening water inlet, such as the water grid 21, inside the fish tank 100, the suction force at the water inlet 111 is increased, effectively increasing the water flow velocity at the filter inlet, thereby effectively adsorbing fish feces and other impurities at the bottom of the tank 30. Moreover, a filter body 12 (such as filter cotton, filter screen, etc.) is installed inside the bottom suction cover 11 of the bottom suction accessory 10, which can adsorb dirt / fish feces on the surface of the filter body 12 and also avoid problems such as easy clogging of the filter. Furthermore, the bottom suction cover 11 completely covers the water inlet of the filter chamber 20, so that the water flow can only pass through the bottom suction accessory 10 before passing through the water inlet. Combined with the setting of the front wall 1103 and the guide plate 114, the problems of low adsorption efficiency of impurities at the bottom of the fish tank and low utilization rate of the filter body are solved simultaneously through the optimization of the flow channel structure.
