Description

Technical Field

[0001] The present application relates to the technical field of filters, and in particular to a filter for fish tanks. Background Art

[0002] When raising fish, the accumulation of fish feces and leftover bait in the water can pollute the aquarium water, producing harmful substances and causing a drop in oxygen levels, leading to hypoxia or even death from poisoning. Currently, there are two main methods for filtering fish feces: physical filtration and biochemical filtration. Physical filtration requires frequent cleaning and replacement of the filter screen. If fish feces are not cleaned promptly, the constant flow of water can easily pollute the water.

[0033] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0034] Reference Figure 1-5A fish tank filter 100 is used to filter water in a fish tank 101, and includes a support plate 102, a filter barrel 103, an end cap 104, a mounting ring 105, a connecting ring 106, a filter screen 107, a retaining ring 108, a first push plate 109, and a fixing member for fixing the end cap 104 to the filter barrel 103. The support plate 102 is located outside the fish tank 101 and is fixedly connected to the fish tank 101.

[0035] The filter barrel 103 is fixedly connected to the support plate 102. The end cover 104 abuts against the filter barrel 103. The mounting ring 105 abuts against the filter barrel 103. The connecting ring 106 is fixedly connected to the mounting ring 105. The filter screen 107 is fixedly connected to the connecting ring 106. The mounting ring 105 is located at the upper end of the connecting ring 106, and the filter screen 107 is located at the lower end of the connecting ring 106. The limiting ring 108 is rotatably connected to the filter barrel 103. Specifically, the filter barrel 103 is provided with a guide groove 103b extending along the circumferential direction of the filter barrel 103, and the limiting ring 108 is partially located in the guide groove 103b and rotates along the guide groove 103b. The first push plate 109 is fixedly connected to the limiting ring 108. Among them, the filter barrel 103 includes a mounting groove 103a, and the mounting ring 105 is provided with a mounting block 105a, and the mounting block 105a is located in the mounting groove 103a.

[0036] The limiting ring 108 is provided with a first avoidance groove 108a, and the first avoidance groove 108a is for the installation block 105a to pass through. A water inlet pipe is provided on one side of the end cover 104, and the water inlet pipe transports water to the filter barrel 103 through a water pump. A water outlet pipe is provided on one side of the filter barrel 103, and the water outlet pipe transports the filtered water to the fish tank 101 through a water pump. Push the first push plate 109, and the first push plate 109 moves to drive the limiting ring 108 to rotate. When the first avoidance groove 108a of the limiting ring 108 moves to the position of the installation block 105a, the installation block 105a can be freed from the restriction of the limiting ring 108, thereby removing the filter screen 107, making it easy to replace the filter screen 107 of the row, and the operation is convenient.

[0037] The fixing parts are used to fix the end cover 104 to the filter barrel 103. There are two groups of fixing parts, which are located on both sides of the filter barrel 103. The fixing parts include: a first fixing plate 110, a second fixing plate 112, a screw 113, and a nut 114. The first fixing plate 110 is fixedly connected to the filter barrel 103. The second fixing plate 112 is fixedly connected to the end cover 104. The screw 113 is fixedly connected to the first fixing plate 110. The nut 114 is threadedly connected to the screw 113. The second fixing plate 112 is provided with a second air avoidance groove 112a, and the second air avoidance groove 112a is for the screw 113 to pass through. The end cover 104 is provided with a first cavity 104a, and the limiting ring 108 and the first push plate 109 are both located in the first cavity 104a. The mounting ring 105 is located at the upper end of the connecting ring 106, and the filter screen 107 is located at the lower end of the connecting ring 106.

[0038] Working process: Push the first push plate 109, and the movement of the first push plate 109 drives the limiting ring 108 to rotate. When the first avoidance groove 108a of the limiting ring 108 moves to the position of the mounting block 105a, the mounting block 105a can be freed from the restriction of the limiting ring 108, thereby taking out the filter 107. After replacing the new filter 107, place the mounting block 105a in the mounting groove 103a of the filter cartridge, and then rotate the limiting ring 108 to limit the mounting block 105a to complete the replacement. The operation is convenient.
