The terms "first," "second," and so on, in the specification, claims, and drawings, are used to distinguish similar items and are not necessarily used to describe a specific sequence or precedence.

[0029] refer to Figure 1 、 Figure 2 and Figure 3 . Figure 1 This is a schematic diagram of the installation of the air curtain start-stop system based on double doors. Figure 2 This is a schematic diagram of the system connection structure of the air curtain start and stop system based on double doors. Figure 3 This is a schematic diagram of the circuit connection structure of the air curtain start and stop system based on double doors.

[0030] The purpose of the utility model is to provide a non-contact air curtain machine start and stop solution, thereby avoiding the reduction of the reliability of the entire air curtain machine start and stop system due to aging of the control line.

[0031] In order to achieve this technical purpose, the present application provides a double-door air curtain start-stop system, including: a wireless transmitting module, a control module, a Hall switch 100, a permanent magnet 200, a power supply terminal VCC, a ground terminal and a wireless receiving module.

[0032] The power supply terminal VCC is connected to the positive electrode of the external battery BAT, the ground terminal is connected to the negative electrode of the external battery BAT, the wireless receiving module is used to connect to the external air curtain machine 300; the control module is connected to the wireless transmitting module and the Hall switch 100 respectively.

[0033] The Hall switch 100 is provided with a magnetic induction area. When the permanent magnet 200 is located in the magnetic induction area, a first signal is outputted. When the permanent magnet 200 is not located in the magnetic induction area, a second signal is outputted.

[0034] The control module controls the wireless transmitting module to send a stop signal according to the first signal; the control module controls the wireless transmitting module to send a start signal according to the second signal; the wireless receiving module requests the air curtain machine 300 to stop generating the air curtain according to the stop signal; the wireless receiving module requests the air curtain machine 300 to start generating the air curtain according to the start signal.

[0035] In the system, the wireless transmitting module, the control module and the Hall switch 100 are mainly powered by the battery BAT. The positive pole of the battery BAT is connected with the power supply end VCC, and the negative pole of the battery BAT is connected with the ground end. The battery BAT provides power for the wireless transmitting module, the control module and the Hall switch 100 through the power supply end VCC and the ground end.

[0036] In the double-door, the Hall switch 100 is installed on one of the doors of the double-door, and the permanent magnet 200 is installed on the other door of the double-door. For the convenience of description, the Hall switch 100 is installed on the left door 101 of the double-door, and the permanent magnet 200 is installed on the right door 102 of the double-door.

[0037] Since the Hall switch 100 is provided with a magnetic induction area for inducting the magnetism of the permanent magnet 200, when the Hall switch 100 inductes the magnetism of the permanent magnet 200 in the magnetic induction area thereof, the Hall switch 100 outputs the first signal. When the Hall switch 100 cannot induct the magnetism of the permanent magnet 200 in the magnetic induction area thereof, the Hall switch 100 outputs the second signal.

[0038] In this way, when the double-door is horizontally opened, the left door 101 and the right door 102 are separated, at this time, the distance between the Hall switch 100 and the permanent magnet 200 is increased, the magnetic induction area of the Hall switch 100 cannot induct the magnetism of the permanent magnet 200, and the Hall switch 100 outputs the second signal.

[0039] When the double-door is horizontally closed, the left door 101 and the right door 102 are in contact, at this time, the distance between the Hall switch 100 and the permanent magnet 200 is reduced. The magnetic induction area of the Hall switch 100 inductes the magnetism of the permanent magnet 200, and the Hall switch 100 outputs the first signal.

[0040] Since the control module is connected with the Hall switch 100, the first signal or the second signal output by the Hall switch 100 is received by the control module.

[0041] In order to enable the air curtain machine 300 to start when the double-door is opened, the control module controls the wireless transmitting module. The control module controls the wireless transmitting module to send a starting signal according to the second signal. Since the wireless transmitting module and the wireless receiving module are connected wirelessly, the wireless receiving module can wirelessly receive the starting signal. The wireless receiving module is connected with the external air curtain machine 300 and transmits the starting signal to the air curtain machine 300, so that the air curtain machine 300 can start according to the starting signal to generate an air curtain.

[0042] In order to make the air curtain machine 300 can realize double door stop when closing the door, therefore, the control module controls the wireless transmitting module, the control module controls the wireless transmitting module to send a stop signal according to the first signal, because the wireless transmitting module and the wireless receiving module are connected wirelessly, therefore, the wireless receiving module can receive the stop signal wirelessly, the wireless receiving module is connected with the external air curtain machine 300, and the stop signal is transmitted to the air curtain machine 300, so that the air curtain machine 300 can stop according to the stop signal, so as to stop generating the air curtain.

[0043] The utility model discloses a hall switch 100 and permanent magnet 200 are set up, and the opening or closing action of double door is obtained through the hall switch 100 and permanent magnet 200, and then the action is transmitted to the wireless receiving module through the wireless mode through the control module and wireless transmitting module, so that the wireless receiving module can request the air curtain machine 300 to start or stop, the action of double door is transmitted wirelessly, reduces the use of wired wire, and improves the reliability of the start or stop of the air curtain machine 300.
