In the embodiment, when the screen door is used, if the screen door is always closed, the power supply and the conductive wire mesh 3 are disconnected, mosquitoes are prevented from entering a room by the screen mesh 2, when someone needs to come out of the room or someone needs to enter the room outside the room, the opening button of the remote controller is pressed down, the infrared emission module emits first infrared rays, after the first infrared rays are received by the infrared receiver, the controller controls the power supply to be communicated with the conductive wire mesh 3, at the moment, the conductive wire mesh 3 is electrified, mosquitoes flying to the screen mesh 2 can be timely and cleanly treated, sounds can be given out when some mosquitoes are treated by the conductive wire mesh 3, and the mosquitoes near the screen door can be favorably driven, so that the possibility that the mosquitoes enter the room can be reduced in the period from the moment that the screen door is closed by someone after the screen door is opened; after the screen door is closed, a closing button of the remote controller is pressed down, so that the infrared transmitting module transmits second infrared rays, and after the second infrared rays are received by the infrared receiver, the controller controls the power supply and the conductive wire mesh 3 to be disconnected, so that the conductive wire mesh 3 is in a power-off state after the screen door is closed, and electric energy is saved.
In addition, here, it is preferable that the conductive wire net 3 is woven with conductive copper wiresThe distance between the conductive copper wires is 2 mm-3 mm, and the cross section area of the conductive copper wires is 1mm2。
As an embodiment, as shown in fig. 2, the door further comprises at least one light source 6, and the light source 6 is fixed on the top of the inner frame of the door frame 1. More mosquitoes can be attracted to the conductive wire mesh 3 before the screen door is opened through the light source 6, so that more mosquitoes around the doorframe 1 can be treated.
As an embodiment, as shown in fig. 2, the door frame further comprises a barrier net, the barrier net is arranged in a direction of the conductive wire net 3 towards the outside of the door frame 1, and the conductive wire net 3 is isolated from a person through the barrier net, so that the conductive wire net 3 is prevented from being touched by the person when the electric power is supplied, and the person is prevented from being electrically injured.
There are several ways of mounting the barrier, for example, the barrier may be embedded in the door frame 1 so that it is fixed and acts as a barrier to the conductive mesh 3.
However, considering that the barrier net may have a reduced pulling force after being applied by an external force for a plurality of times, and there is a possibility that the human body may contact the conductive net 3 after the pulling force is reduced to a certain degree, as shown in fig. 2, 3, 4 and 5, the barrier net includes a longitudinal pulling portion and a transverse pulling portion, the barrier net includes a longitudinal barrier net 4 and a transverse barrier net, the bottom of the longitudinal barrier net 4 is fixed to the bottom of the inner frame of the door frame 1, the top of the inner frame of the door frame 1 is provided with a top groove 9, the longitudinal pulling portion is fixed to the top groove 9 and is in dynamic connection with the top of the longitudinal barrier net, the left side of the transverse barrier net is fixed to the left inner frame portion of the door frame 1, the right portion of the door frame 1 is provided with a lateral groove, and the transverse pulling portion is fixed to the lateral groove and is in dynamic connection with the right side of the transverse barrier net 5.
In this embodiment, when the pulling force of the barrier net is reduced, the longitudinal pulling portion and the transverse pulling portion allow the interior of the barrier net to have sufficient pulling force, so that the possibility that the human body contacts the conductive wire net 3 after the pulling force is reduced to a certain degree can be avoided.
As an embodiment, as shown in fig. 3, the longitudinal pulling portion includes a first motor 8 and a first rotating shaft 7, the first motor 8 is fixed to the left portion of the top slot 9, an output shaft of the first motor 8 is connected to the left end of the first rotating shaft 7 through a coupling, and the right end of the first rotating shaft 7 is connected to the right portion of the top slot 9 through a bearing;
the transverse pulling part comprises a second motor 11 and a second rotating shaft 12, the second motor 11 is fixed at the bottom of the side groove 10, an output shaft of the second motor 11 is fixedly connected with the bottom end of the second rotating shaft 12 through a coupler, and the top end of the second rotating shaft 12 extends into the top groove 9 and is connected with the top side wall of the top groove 9 through a bearing;
the first rotating shaft 7 and the second rotating shaft 12 are crossed in the top groove 9 and are perpendicular to each other.
In this embodiment, after the net pulling force is reduced, the first motor 8 and the second motor 11 may be started, the first motor 8 may increase the pulling force of the longitudinal net pulling force to a suitable magnitude again through the first rotating shaft 7, and the second motor 11 may increase the pulling force of the transverse barrier net 5 to a suitable magnitude again through the second rotating shaft 12.
When the barrier has the appropriate tension within it, if only the first motor 8 and the second motor 11 are used, it is required that the first motor 8 and the second motor 11 are always in the on state, which not only consumes power, but also because both the first motor 8 and the second motor 11 cannot rotate, the service life of the first motor 8 and the second motor 11 is greatly reduced, and therefore, as an embodiment, as shown in fig. 4 and 5, the device further comprises a cylinder 13 and a fastening member 14, wherein an upper end surface of the fastening member 14 is provided with a fastening groove 16 along the axial direction of the first rotating shaft 7, a lower end surface of the fastening member 14 is provided with a groove 15 along the axial direction of the second rotating shaft 12, a part of the side surface of the first rotating shaft 7 is located in the fastening groove 16, the cylinder 13 is fixed in the top groove 9, and an output shaft of the cylinder 13 is fixed to one side of the fastener 14 for driving the fastener 14 to move in the axial direction of the first rotary shaft 7.
In this embodiment, the fastening member 14 has a certain elasticity, and when the pulling force inside the net is appropriate, the side surface of the second rotating shaft 12 contacts with the lower end surface of the fastening member 14, and at this time, the first rotating shaft 7 has an extrusion force on the fastening member 14 and the second rotating shaft 12 has an extrusion force on the fastening member 14, so that the first rotating shaft 7 and the second rotating shaft 12 cannot rotate, and thus, after the pulling force of the net is adjusted, the first motor 8 and the second motor 11 can be powered off. When the internal pressure of the net puller needs to be adjusted, at this time, the cylinder 13 is started firstly, the cylinder 13 drives the fastening piece 14 to move axially along the first rotating shaft 7, so that a part of the side surface of the second rotating shaft 12 coincides with the groove 15, the extrusion force of the first rotating shaft 7 to the fastening piece 14 and the extrusion force of the second rotating shaft 12 to the fastening piece 14 are reduced, and at this time, the pulling force in the net puller can be adjusted after the first motor 8 and the second motor 11 are started.
