Abstract

The utility model provides an air-inflated water lift pump for aquaria. The air-inflated water lift pump for aquaria is characterized in that a water outlet of the water lift pump is provided with a branch pipe, wherein, a water outlet pipe of the branch pipe is connected with a water pipe communicated with a water filtering tank, and the other water outlet pipe of the branch pipe is communicated with the water of an aquarium; the upper part of the branch pipe is provided with an air inlet pipe communicated with atmosphere. The filter also has air inflating and oxygen increasing functions besides the functions of general water lift pumps. With simple and compact structure, easy fabrication, convenient installation and operation and lower energy consumption, the utility model is suitable for aquaria to use.

Description

A kind of aquarium is with inflating lift pump

The utility model belongs to the pump class, and particularly a kind of aquarium is suitable for the aquarium filtering water and uses with the inflation lift pump.

In order to solve aquarium oxygenation problem, way commonly used is with a little electromagnetic pump air to be charged in the water, but not enough be to have occupied a part of volume, and influenced the outward appearance of aquarium, increased expense again.China's utility model patent (ZL95213736.4) discloses " a kind of aquarium inflatable filter device ", the immersible pump of this filter has two delivery ports, one of them is communicated with aquarium, another delivery port is connected with drainage trap by water pipe, be provided with an air inlet in the water inlet of immersible pump, this air inlet is communicated with atmosphere by a breather pipe.This filter is that the negative pressure of utilizing immersible pump water inlet place to produce is brought air in the pump into, is entered in the water tank by delivery port and reaches the purpose of blowing aeration.Through facts have proved after a while, this filtration China ink still has the following disadvantages: the gas that mainly is suction can not enter in the water fully, and some gas can lead to lautertuns with water pipe runs away, and has caused waste, secondly is also inconvenience is installed.Though afterwards air inlet pipe was arranged on outlet pipe that aquarium is communicated with on solve, also have following problem, two delivery ports will be symmetrical arranged, and take more place, and not attractive in appearance.In addition, owing in the immersible pump two delivery ports are arranged, power of motor will increase just can reach the requirement of drawing water.

The purpose of this utility model is the problem that exists at above-mentioned filtration China ink, provide a kind of compact conformation, easy to install, easily make and aquarium that energy consumption is lower with the inflation lift pump.

Fig. 1 is the schematic diagram of the utility model concrete structure.

Above-mentioned task is achieved in that this pump includes a lift pump (1), it is characterized in that locating to be connected to a breeches pipe (3) at the delivery port (2) of lift pump (1), the upper water-out pipe (4) of breeches pipe (3) is connected with lifting pipe (5), another downward-sloping outlet pipe (6) is communicated with the water of aquarium, and is provided with an air inlet pipe that is communicated with atmosphere (7) thereon.

This filter is work like this; After starting lift pump, water sucks from the water inlet of pump, breeches pipe (3) through delivery port (2) is divided into two-way, the one road flows to drainage trap through lifting pipe (5), flow back to after filtering in the aquarium, another road directly sprays in the aquarium, meanwhile through outlet pipe (6), the negative pressure that is produced in water flow process is also taken air the water to from air inlet pipe (7), thereby has realized the blowing aeration requirement.

This filter compared with prior art has following advantage;

1, outlet pipe and air inlet pipe concentrate on one side, seem compact, attractive in appearance.

2, only on existing lift pump, connect a breeches pipe and air inlet pipe just can reach the blowing aeration requirement, do not need, easy manufacturing and applying pump structure transforms of pumping up water.

3, the air of suction can all be poured in the water, and oxygenation effect is good.

4, immersible pump remains a delivery port, not loss power of motor too much.

When implementing, in order to improve the aeration quantity of water pump, the center of water pipe (6) is preferably stretched in the gas outlet of air inlet pipe (7).Because the center flow velocity of water pipe is the fastest, the negative pressure that produces at the place, gas outlet of air inlet pipe (7) is local higher than other, thereby can obtain higher exhaust capacity.

The utility model is suitable for aquarium filter sewage and oxygenation is used.

Claims

1, a kind of aquarium is with inflating lift pump, include a lift pump (1), it is characterized in that locating to be connected to a breeches pipe (3) at the delivery port (2) of lift pump (1), the upper water-out pipe (4) of breeches pipe (3) is connected with lifting pipe (5), another downward-sloping outlet pipe (6) is communicated with the water of aquarium, and is provided with an air inlet pipe that is communicated with atmosphere (7) at it.

2, lift pump according to claim 1 is characterized in that the gas outlet of air inlet pipe (7) stretches into the center of water pipe (6).
