Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Referring to fig. 1, the venturi tube includes a tube body 4, a water inlet 1 located at one end of the tube body 4, a water outlet 5 located at the other end of the tube body 4, and an air inlet 3 located at the middle of the tube body 4, wherein the tube body 4 further has a water flow sensor 2 capable of detecting whether water flows through the tube body 4.

During the application, ozone generator's ozone delivery outlet links to each other with above-mentioned air inlet 3, is connected rivers inductor 2 and ozone generator electricity, can be in there being rivers to pass through during the pipe body 4, automatic control ozone generator starts, and the ozone of production is inhaled by venturi and is mixed with rivers. I.e. an automatic control of the water purification can be achieved.

The water purifier is constructed by the Venturi tube without arranging a sensor and a controller, so that the water purifier can be conveniently and quickly constructed, and the structure of the water purifier can be simplified.

Further, the water flow sensor 2 is positioned between the air inlet 3 and the water inlet 1, and when water flows through the pipe body 4, the ozone generator can be started in time.

Fig. 2 and 3 show an embodiment of the water flow sensor 2. The water flow sensor 2 comprises a base pipe 22, a first magnetic member 25, a second magnetic member 21 and a position sensor 26, wherein the first magnetic member 25 and the second magnetic member 21 are oppositely installed inside the base pipe 22, the first magnetic member 25 is fixed, the second magnetic member 21 is located on the side of the first magnetic member 25 close to the water inlet 1, is spaced from the first magnetic member 25 by a certain distance, and forms a repulsive magnetic field with the first magnetic member 25, the second magnetic member 21 can move along the direction of the central line of the base pipe 22, the first magnetic member 25 and the second magnetic member 21 are respectively provided with a water flow channel, and the position sensor 26 is installed on the side of the base pipe 22 close to the first magnetic member 25 to sense whether the second magnetic member 21 moves towards the first magnetic member 25. Position sensors 26 that may be used include, but are not limited to, hall switches, photoelectric switches. The base pipe 22 is provided at its side with mounting slots in which the position sensors 26 are disposed. The first magnetic member 25 includes a non-metallic first body and a first magnet 24 provided to the first body; the second magnetic member 21 includes a second body and a second magnet 23 disposed on the second body, and the non-metallic material includes, but is not limited to, plastic and ceramic. As another embodiment, the magnetic powder is dispersed in a non-metallic material, and the first and second

magnetic members

25 and 21 are directly made of the non-metallic material containing the magnetic powder. The water flow sensor 2 has no spring and metal parts inside, can not be rusted, and has the characteristics of long service life and high reliability.

The working principle of the water flow sensor 2 is as follows: when there is no water, the repulsive magnetic field keeps the second magnetic member 21 in the state shown in fig. 2, and when there is water, the water generates pressure on the second magnetic member 21, so that the second magnetic member 21 overcomes the pressure of the repulsive magnetic field and moves in a direction close to the first magnetic member 25, as shown in fig. 3, when the second magnetic member 21 moves to the position, the position sensor 26 senses the position, and the output voltage of the position sensor 26 changes, thereby achieving the purpose of detecting the water flow. Meanwhile, water passes through the water flow channels on the first magnetic member 25 and the second magnetic member 21 and is output from the water outlet 5.

The working principle of the venturi tube is as follows: the water that water inlet 1 got into flows from delivery port 5 behind rivers inductor 2, and at this in-process, the output voltage of rivers inductor 2 changes, triggers supporting ozone generator to start, produces ozone, and venturi inhales ozone through air inlet 3, forms after mixing with water and contains the ozone water, flows out from delivery port 5.

The present invention has been described in detail with reference to the specific embodiments, and the detailed description is only for assisting the skilled person in understanding the content of the present invention, and can not be understood as the limitation of the protection scope of the present invention.
