Description

Technical Field

[0001] The utility model relates to the technical field of fish tanks, and in particular to an external fish tank. Background Art

[0002] With the development of society, more and more people are starting to raise fish. The high ornamental value of fish tanks can not only beautify the living space, but also relax the body and mind and improve the quality of life. Fish tanks need to oxygenate or filter the water quality to improve the living environment of aquatic organisms and avoid illness or death due to water quality problems. However, most of the filtration equipment on the market currently places water pump equipment in the water or in contact with the water body. Water is pumped into the filter tank through a water pump. During the extraction process, impurities in the water will pass through the inside of the water pump and then be transported to the filter tank. Over time, impurities will adhere to the inside of the water pump, causing blockage or bacterial growth inside the water pump. At the same time, water pump equipment placed in water has the risk of leakage.

[0003] Currently, there is a fish tank on the market, in which the tank body and the storage pad are connected by weight combination. However, when the tank body is light, sealed connection cannot be achieved, which may lead to insufficient sealing performance and even affect the normal use of the fish tank. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an external fish tank. Specifically, the technical solution adopted is as follows:

[0005] An external fish tank comprises a cylinder body, a cylinder gasket and a check valve. A cylinder gasket is provided at the bottom of the cylinder body, an opening is provided at the bottom of the cylinder body, the opening is connected to the check valve, the outlet end of the check valve is connected to the inside of the cylinder body, and the inlet end of the check valve leads to the outside of the cylinder body. The cylinder gasket is provided with an air inlet, one end of the air inlet is connected to the inlet end of the check valve, and the other end of the air inlet can be connected to the air outlet of an air pump. When the air pump delivers gas, the gas will pass through the air inlet to the inlet end of the check valve.

[0006] Furthermore, the cylinder gasket is connected to the bottom of the cylinder body, and a vent is provided at one end of the cylinder gasket, and the inlet end of the check valve is connected to the air inlet through the vent.

[0007] Furthermore, the air inlet is connected to one end of a pipeline, and the other end of the pipeline is connected to an inlet end of the check valve through the air vent.

[0008] Furthermore, the air inlet is adapted to the air outlet of the air pump and can be connected or separated.

[0009] Furthermore, an air bubble stone is provided at the outlet end of the check valve, which can oxygenate the water in the cylinder in the form of bubbles to improve the viewing experience.

[0010] Furthermore, the bubble stone at the outlet end of the check valve can be replaced with an upper water pipe, which is a vertically arranged straight tubular structure. The lower end of the upper water pipe is connected to the outlet end of the check valve. A downward inclined water inlet pipe is provided on the side of the lower end of the upper water pipe. A filter box is provided at the upper end of the upper water pipe. The filter box is provided with a pipe hole and a reflux hole. The water outlet at the upper end of the upper water pipe passes through the pipe hole of the filter box, and the water at the outlet will flow back to the inside of the cylinder through the reflux hole to complete the filtration.

[0011] Furthermore, the connection between the water supply pipe and the outlet end of the check valve is arranged to be dockable and separable, so that the water supply pipe and the outlet end of the check valve can be separated and cleaned conveniently.

[0012] Furthermore, the cylinder body is provided with a cover, and the cover can prevent bubbles from bursting or overflowing water from splashing everywhere.

[0013] Connect the air inlet to the air pump, and use the gas delivered by the air pump to push the water inside the water pipe upward to overflow from the water outlet. After the overflowing water is filtered by the filter medium of the filter box, it flows downward through the reflux hole to complete the reflux, and filtration and oxygenation are completed in this process.

[0014] By adopting the above technical solution, the beneficial effects of the utility model are:

[0015] Compared with the prior art, the cylinder gasket of the utility model is connected to the bottom of the cylinder body, and has no requirements on the weight and size of the cylinder body. At the same time, the cylinder gasket can play a decorative and protective role in daily use, preventing the cylinder body from being broken due to bumps when placed. It only needs to connect the air inlet of the cylinder gasket with the air outlet of the air pump, and use the gas delivered by the air pump to achieve the filtering and oxygenation effect, avoiding clogging or breeding of bacteria inside the water pump due to the use of the water pump, and the water inside the cylinder body does not contact with live equipment, avoiding leakage, improving safety, low cost, simple structure, simple use, and easy maintenance.
