Description

Technical Field

[0001] The utility model relates to a fish tank water changing device, in particular to an automatic water changing siphon drainer for a fish tank. Background Art

[0002] In daily life, users who like to raise fish in fish tanks know that the water in the fish tank needs to be replaced regularly. When changing the water, in order to ensure the activity of the fish, the water in the fish tank is usually replaced in multiple times, such as only replacing 1 / 4 or 1 / 3 of the total water each time, and each water change cycle is about one week, which makes the water change process very troublesome and requires regular supervision by fish enthusiasts. For this reason, technicians in this field have proposed a drainer that relies on the siphon principle to automatically change the water in the fish tank. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides an automatic water-changing siphon drainer for a fish tank, which solves the problems raised by the above-mentioned background technology.

[0004] To achieve the above purpose, the utility model is implemented through the following technical scheme: an automatic water-changing siphon drainer for a fish tank, comprising a bracket movably arranged on the edge of the fish tank, a water pump and a liquid level sensor are respectively installed on the back of the bracket, the liquid level sensor is located on the upper part of the water pump, the liquid outlet end of the water pump is connected to a water pipe, the liquid outlet end of the water pipe is connected to the inlet of a three-way pipe, and the outlet of the three-way pipe is respectively connected to a drain pipe and an exhaust pipe.

[0005] Furthermore, the front and top of the bracket are provided with a first wiring path and a second wiring path.

[0006] Furthermore, a plurality of wiring limiters are connected inside the wiring channel 1 and the wiring channel 2.

[0007] Furthermore, the water pipe extends along the direction of the first wiring path, and the exhaust pipe extends along the direction of the second wiring path.

[0008] Furthermore, a water pump installation position and a sensor installation position are respectively provided on the back side of the bracket.

[0009] Furthermore, the water pump is installed inside the water pump installation position, and the liquid level sensor is installed on the sensor installation position.

[0010] The utility model provides a siphon drainer for automatically changing water in a fish tank. Compared with the prior art, it has the following beneficial effects:

[0011] When changing water in a fish tank, the drainer can progressively perform different automatic drainage modes according to the changes in the water level in the fish tank. On the basis of the previous water pump drainage, negative pressure is formed in the pipeline, thereby forming the latter siphon drainage mode. The entire water changing process is automatic, without the need for human intervention, and is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-6The utility model provides a technical solution: an automatic water-changing siphon drainer for a fish tank, comprising a bracket 1 movably arranged at the edge of a fish tank 8, a water pump 2 and a liquid level sensor 3 are respectively installed on the back of the bracket 1 (the water pump 2 and the liquid level sensor 3 are connected to a power supply through a cable plug), the liquid level sensor 3 is located at the upper part of the water pump 2, the liquid outlet end of the water pump 2 is connected to a water delivery pipe 4, the liquid outlet end of the water delivery pipe 4 is connected to the inlet of a three-way pipe 5, and the outlet of the three-way pipe 5 is respectively connected to a drainage pipe 6 and an exhaust pipe 7.

[0022] In addition, a wiring path 11 and a wiring path 2 12 are provided on the front and top of the bracket 1. The water pipe 4 extends along the direction of the wiring path 11, and the exhaust pipe 7 extends along the direction of the wiring path 2 12. The insides of the wiring path 11 and the wiring path 2 12 are both connected with a plurality of wiring limit members 13 (the water pipe 4 and the exhaust pipe 7 are limited and constrained by the wiring limit members 13). The back of the bracket 1 is respectively provided with a water pump installation position 14 and a sensor installation position 15. The water pump 2 is installed inside the water pump installation position 14, and the liquid level sensor 3 is installed on the sensor installation position 15.

[0023] When in use, place the siphon drain as follows: Figure 6 Place it in the position shown, see Figure 7 When the water is not changed, the initial height of the liquid level is L1. When the water needs to be changed, turn on the faucet, the liquid level of the water in the fish tank 8 will continue to rise. When the liquid level reaches the position of the liquid level sensor 3, the height at this time is L2, and the water pump 2 starts to work. The water is pumped away through the water pipe 4 and discharged through the drain pipe 6. The gas is discharged from the exhaust pipe 7, thereby pumping out the water in the fish tank 8. At this time, the liquid level begins to drop. The arbitrary height between L1 and L2 is L3. When the liquid level is lower than the position of the liquid level sensor 3, the water pump 2 stops working. However, based on the previous negative pressure, although the water pump 2 does not work, the water in the fish tank 8 is still continuously discharged under the action of siphon, that is, when the liquid level is at L3, this stage is the siphon effect, and automatic water change can be achieved without electrical energy. Water is pumped here and released there. Eventually, the liquid level will return to L1, and the water will no longer be discharged. Just turn off the faucet, and the water change work is also completed.
