Description

Technical Field

[0001] The utility model mainly relates to the technical field of fish tank cleaning, and specifically relates to a fish tank water changer. Background Art

[0002] A fish tank water changer is a tool specifically used for changing water in a fish tank. It usually uses the siphon principle or electric pump suction technology to extract the old water in the fish tank and can add fresh water source at the same time. The valves of the existing fish tank water changers are prone to poor sealing, resulting in water leakage. Moreover, during the water changing process of the fish tank water changer, the valve cannot be controlled to close the water outlet, and it cannot flexibly respond to emergencies. For example, after a foreign object blocks the water suction port, it is necessary to stop working and quickly close the valve. Therefore, the utility model provides a fish tank water changer. Content of the Utility Model

[0003] In order to solve the problems of the existing technology, the utility model provides a fish tank water changer.

[0004] To achieve the above object, the utility model is realized through the following technical solutions:

[0005] A fish tank water changer includes a water pipe fitting. A rotary valve is arranged on the upper part of the water pipe fitting. The water pipe fitting includes a vertical water pipe, a horizontal water pipe and a connecting pipe. The rotary valve includes a rotary handle and a water control joint. A first through hole horizontally penetrating is opened at the bottom of the water control joint. A second through hole communicating with the first through hole is opened at the bottom end of the water control joint. A plurality of semi-circular grooves are arranged on the water control joint from top to bottom. The semi-circular grooves are respectively provided with a first sealing ring, a second sealing ring and a third sealing ring. First sealing gaskets are symmetrically arranged at both ends of the first through hole. Second sealing gaskets are symmetrically arranged on both sides of the symmetric first sealing gaskets.

[0006] An annular groove and a clamping groove are arranged at the top of the connecting pipe. A clamping block is arranged inside the rotary valve. The rotary valve is rotationally connected with the connecting pipe through the annular groove.

[0007] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0008] The utility model uses multiple sealing rings for sealing, and the sealing effect is good. By arranging the first sealing gasket and the second sealing gasket, and further controlling the first sealing gasket or the second sealing gasket corresponding to the horizontal water pipe by rotating the rotary valve, the on-off of the water flow can be realized, and the size of the water flow can also be adjusted by controlling the size of the first through hole corresponding to the horizontal water pipe. It is more convenient and flexible to use. Description of the Drawings

Detailed implementation manners

[0015] In combination with the drawings and specific embodiments, the present utility model will be further described. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0016] As Figure 1 shown, a fish tank water changer includes a water pipe fitting 1, a rotary valve 2 is arranged on the upper part of the water pipe fitting 1. The water pipe fitting 1 includes a vertical water pipe 101, a horizontal water pipe 102 and a connecting pipe 103. The rotary valve 2 includes a rotary handle 201 and a water control joint 202. A horizontally penetrating first through hole 3 is opened at the bottom of the water control joint 202. A second through hole 4 communicating with the first through hole 3 is opened at the bottom end of the water control joint 202. A plurality of semi-circular grooves 5 are arranged on the water control joint 202 from top to bottom. The semi-circular grooves 5 are respectively provided with a first sealing ring 6, a second sealing ring 7 and a third sealing ring 8. First sealing pads 9 are symmetrically arranged at both ends of the first through hole 3. Second sealing pads 10 are symmetrically arranged on both sides of the symmetric first sealing pads 9.

[0017] An annular groove 11 and a clamping groove 12 are arranged at the top of the connecting pipe 103. A clamping block 13 is arranged inside the rotary valve 2. The rotary valve 2 is rotationally connected to the connecting pipe 103 through the annular groove 11.

[0018] Working principle:

[0019] By setting the first sealing ring, the second sealing ring and the third sealing ring, a better sealing effect can be achieved. The first sealing gasket and the second sealing gasket are set. Further, by rotating the rotary valve to control the first sealing gasket or the second sealing gasket corresponding to the horizontal water pipe, the on-off of the water flow can be realized, which is convenient for controlling the water change process. When, for example, a foreign object blocks the water suction port and it is necessary to stop working, the valve can be quickly closed to stop the water change. Also, the size of the water flow can be adjusted by controlling the size of the first through hole corresponding to the horizontal water pipe, making it more convenient and flexible to use.

[0020] During use, the second sealing gasket is directly opposite to the horizontal water pipe. The second sealing gasket bulges and has the function of sealing water. The device is in a closed state. Hold the rotary head and drive the water control joint to rotate 90°, so that the first sealing gasket is directly opposite to the horizontal water pipe. At this time, the device is turned on and the fish tank water changer can work. Continue to rotate 90°, and the device returns to the closed state.
