Description

Antifouling water reflux unit and fish bowl filter

Technical Field

The utility model relates to a fish bowl filter technical field especially relates to an antifouling water reflux unit and fish bowl filter.

Background

The fish tank filter is a device for purifying water and supplementing oxygen in a fish culture appliance, and the purpose is as follows: remove the dirt such as excrement and urine in the water, keep the water clear, the oxygen is sufficient, do not have harmful substance, pollution-free, be fit for the growth of fish. The fish tank is internally provided with a good filtering device, so that fishes can be cultured and water is changed less.

The water inlet is opened to current small-size fish bowl dive filter all adopts the wall to intake, when needs trade the filter core or wash the filter core, takes out a large amount of sewage in the middle of the filter's the process and can flow back, and the sewage backward flow can cause the inside water of fish bowl to receive the pollution to cause the death of the inside fish of fish bowl easily, and at this time either trades water, or spends a large amount of time to filter again.

Therefore, it is necessary to provide an anti-sewage backflow device and a fish tank filter to solve the above problems.

SUMMERY OF THE UTILITY MODEL

The utility model provides an antifouling water reflux unit and fish bowl filter has solved the problem that sewage can flow back when taking out the filter.

In order to solve the technical problem, the utility model provides an antifouling water reflux unit, include: a clip;

the clamp plate is internally clamped with a silica gel sheet through a groove, the silica gel sheet is evenly provided with a u-shaped slit, and the silica gel sheet and the u-shaped slit form opening and closing conditions for water to flow through.

Preferably, the number of the clips is at least four.

Preferably, the clamping piece can be made of plastic or metal, and the plastic needs to be shaped once to be less than 2 mm in thickness.

Preferably, the thickness in the middle of the silica gel sheet is higher than the thickness around.

A fish tank filter comprises a filter body and an antifouling water backflow device, wherein the antifouling water backflow device is clamped on the filter body through a fixing block.

Compared with the prior art, the utility model provides an antifouling water reflux unit and fish bowl filter have following beneficial effect:

the utility model provides an antifouling water reflux unit and fish bowl filter, this antifouling water reflux unit adopt flexible material such as silica gel, and it is less to influence the filter influence of intaking not influencing the filter during operation when the filter, and when the filter was closed, the inlet opening was plugged up to the silica gel piece, can stop the sewage backward flow completely to avoid sewage to get into the pollution that the fish bowl water caused.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

Please refer to fig. 1-6, wherein fig. 1 is a schematic structural diagram of the sewage backflow prevention device according to the present invention; fig. 2 is a schematic three-dimensional structure diagram of a silica gel sheet of the sewage backflow prevention device provided by the present invention; fig. 3 is a schematic diagram of a three-dimensional structure of a clamping piece of the sewage backflow prevention device provided by the present invention; fig. 4 is a schematic structural view of a fish tank filter provided by the present invention; FIG. 5 is a top view of the filter body shown in FIG. 4; fig. 6 is an enlarged view of the portion a shown in fig. 4. An anti-sewage backflow device comprising: a clamping piece 4;

the clamping piece 4 is internally clamped with a silica gel piece 5 through a groove, the silica gel piece 5 is evenly provided with a u-shaped slit, and the silica gel piece 5 and the u-shaped slit form an opening and closing condition for water flow to flow through.

The clamping piece 4 can be made of plastic or metal, and the plastic needs to be shaped once to be less than 2 mm in thickness.

The number of the clips 4 is at least four, preferably twelve clips 4, and the clips are uniformly distributed in the filter body 1.

The thickness of the middle of the silica gel sheet 5 is higher than the thickness of the periphery.

The utility model provides an antifouling water reflux unit's theory of operation as follows:

when sewage need get into filter body 1's inside, because the impact force of water can make silicon sheet 5 open to make sewage get into filter body 1's inside, and when filter body 1 does not have the impact force of sewage, inlet opening 8 can be plugged up to silicon sheet 5, thereby avoids the backward flow of sewage.

Compared with the prior art, the utility model provides an antifouling water reflux unit has following beneficial effect:

this antifouling water reflux unit adopts flexible material such as silica gel, and it is less to influence filter intake or intake the influence to the filter when the filter during operation, and when the filter was closed, inlet opening 8 was plugged up to silica gel piece 5, can stop the sewage backward flow completely to avoid sewage to get into the pollution that the fish bowl water caused.

Referring to fig. 4 to 6, a fish tank filter includes a filter body 1 and an anti-sewage backflow device according to any one of claims 1 to 4, the anti-sewage backflow device being fastened to the filter body 1 by a fixing block 2.

1 inboard of filter body is provided with fixed block 2, joint groove 3 has been seted up on fixed block 2, the inside and the 4 sliding connection of clamping piece of joint groove 3, shell connecting hole 6 has been seted up on filter body 1 to outer shell base connecting hole 7 has been seted up to filter body 1's bottom, a plurality of inlet openings 8 have been seted up on filter body 1.
