Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, for this embodiment discloses a water tank is with preventing flowing backward air exchange system, including water tank body 1, water tank body 1 top intercommunication has vertical blast pipe 2, the upper end intercommunication of blast pipe 2 has intake pipe 3 and outlet duct 4 to form the tee bend pipeline, intake pipe 3 is mutually opposite with the mouth of pipe of outlet duct 4, intake pipe 3 is linked together with 4 one end of outlet duct, the other end extends the setting downwards to one side, the preferred 10-20 degrees of contained angle of intake pipe 3 and outlet duct 4 and top horizontal plane play and prevent that the rainwater from getting into can.

Referring to fig. 3 and 4, the bottom of the exhaust pipe 2 is rotatably connected with the water tank body 1 through a bearing, the outer side wall of the exhaust pipe 4 is a frosted surface with a large friction coefficient, a guide plate 6 for increasing the contact surface with natural wind is arranged on the outer side wall of the exhaust pipe 4, and the guide plate 6 is vertically arranged. When natural wind blows to the side faces of the air outlet pipe 4 and the air inlet pipe 3, the air resistance received by the air outlet pipe 4 is larger than that received by the air inlet pipe 3, so that the pipe opening of the air inlet pipe 3 is easy to deflect to the direction blown by the natural wind.

Referring to fig. 2 and 4, the exhaust pipe 2 includes a connection pipe 7 disposed at the bottom of the connection between the exhaust pipe 4 and the intake pipe, and a mounting pipe 8 connected to the water tank body 1, and the connection pipe 7 is axially parallel to the vertical direction. The lower end of the outer wall of the connecting pipe 7 is provided with an external thread, and the upper end of the inner wall of the mounting pipe 8 is provided with an internal thread matched with the external thread of the connecting pipe 7. Through the external screw thread with connecting pipe 7 and the internal thread spiro union cooperation of installation pipe 8, can install connecting pipe 7 on installation pipe 8. The top of the inner wall of the connecting pipe 7 is provided with a filter screen 5 at the position communicated with the air inlet pipe 3 and the air outlet pipe 4, and the upper surface of the filter screen 5 is upwards protruded and is an arc surface. The connecting parts among the connecting pipe 7, the air inlet pipe 3 and the air outlet pipe 4 are in welded connection.

Referring to fig. 2 and 4, in order to prevent rainwater from pouring into the connecting pipe 7, the highest point on the pipe orifice of the air inlet pipe 3 and the pipe orifice of the air outlet pipe 4 which are opposite to each other is lower than the pipe orifice of the upper end of the connecting pipe 7. In order to increase the flow rate of air at the upper end of the connecting pipe 7, the pipe diameters of the air inlet pipe 3 and the air outlet pipe 4 are gradually increased from the upper end of the connecting pipe 7 to a direction away from the connecting pipe 7.

The implementation principle of the embodiment is as follows: when natural wind blows to this device, because be provided with frosted surface and deflector 6 on outlet duct 4, so outlet duct 4 will receive the windage bigger than intake pipe 3, again because blast pipe 2 rotates through the bearing to be connected on water tank body 1 to make intake pipe 3 deflect easily to the direction that natural wind blows, make in partial natural wind blows in intake pipe 3, and blow off from outlet duct 4. Referring to the direction of the arrow in fig. 4, when the gas flow velocity above the pipe orifice at the upper end of the connecting pipe 7 is faster, a negative pressure region will be formed above the connecting pipe 7, so that the gas below the exhaust pipe 2 is sucked upwards, and finally the ventilation effect of the exhaust pipe 2 is enhanced. Under the windless condition, air can still enter the water tank body 1 from the air inlet pipe 3 and the air outlet pipe 4 to play a role in air exchange.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
