Wherein, the valve plate 42 is perpendicular to the axis of the flow passage 411. Therefore, when the push rod stretches, the valve plate 42 can be driven to slide back and forth along the sliding groove, so that the overlapping size of the valve plate 42 and the flow channel 411 in the axial direction of the flow channel 411 is changed, the opening degree of the flow channel 411 is further adjusted, and the flow channel 411 is switched between an open state and a closed state.

Wherein the position of the valve sheet 42 corresponding to the closed state of the flow passage 411 can be set at the stroke end point of the push rod, which can simplify the control of the push rod.

In an alternative embodiment, a travel switch may also be provided in the valve body to control the state of motion of the push rod.

In another alternative embodiment, the driving device 43 is a motor, the transmission structure 44 is a rack and pinion engaged with each other, the rack is connected to the valve plate 42, and the pinion is fixedly connected to an output shaft of the motor, so that the valve plate 42 can be controlled to slide back and forth by controlling the motor to rotate forward and backward.

Further, when the driving device 43 is a stepping motor, the sliding distance of the valve plate 42 can be controlled by controlling the rotation angle of the stepping motor, so that the flow area in the flow channel 411 can be adjusted, and the adjustment of fresh air intake in unit time can be realized.

EXAMPLE III

Referring to fig. 5 and 6, the present embodiment provides an air conditioning system including: fresh air pipeline 7, fresh air source and air pipe machine in the above embodiment; the fresh air converter 4 of the air pipe machine is fixedly arranged on the outer side of the shell 1 of the air pipe machine; the fresh air pipeline 7 is connected with the fresh air converter 4 and communicates the fresh air converter 4 with a fresh air source.

Specifically, the fixing surface of the fresh air converter 4 is matched with the fresh air port 13 of the shell 1 in a face-to-face manner, the fresh air converter 4 is fixed on the corresponding fixing hole of the shell 1 by using a screw, and the other end of the fresh air converter 4 is connected with the fresh air exchange pipeline 7 in a sealing manner so as to realize the connection of the fresh air converter 4 with the shell 1 and the fresh air pipeline 7.

Example four

The difference between this embodiment and the third embodiment is that the fresh air converter 4 is an electromagnetic valve, and the electromagnetic valve is connected in series between the fresh air inlet 13 and the fresh air duct 7.

Through the above setting mode, the fresh air converter 4 is convenient to control, is correspondingly rapid, and can be rapidly switched between the opening state and the closing state. Those skilled in the art will appreciate that although some embodiments described herein include some features included in other embodiments instead of others, combinations of features of different embodiments are meant to be within the scope of the invention and form different embodiments. For example, in the claims of the present invention, any of the claimed embodiments may be used in any combination.

So far, the technical solution of the present invention has been described with reference to the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, a person skilled in the art can make equivalent changes or substitutions to the related technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
