[0033] In order to enable more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below with reference to the accompanying drawings, which are only used for reference and do not limit the embodiments of the present application.

[0034] The embodiments of the present application provide an information interaction method, Figure 1 The first flowchart of the information interaction method in the embodiments of the present application is shown in FIG. 1.

[0035] Figure 1 The information interaction method shown in the embodiments of the present application is applied to an air conditioner, which includes a main machine and a sub-machine. The main machine includes a first socket, and the sub-machine includes a second socket corresponding to the first socket. In this regard, the present application provides an air conditioner structure diagram, Figure 2 The air conditioner structure diagram in the embodiments of the present application is shown in FIG. 2. Figure 2 As shown in FIG. 2, the air conditioner structure includes an upper air conditioner main component and a lower extended function component. The upper air conditioner main component implements basic functions of the air conditioner such as refrigeration and heating. The lower extended function component includes a lower air duct air inlet side part and an upper air duct air outlet side part. The air duct cavities of the upper air duct and the lower air duct are connected. The lower air duct air inlet side part includes an air inlet valve assembly. The upper air duct air outlet side part includes an installation cavity (including the first socket) of one or more sub-machines (which can also be referred to as plug-in function modules) and an air outlet valve assembly. The sub-machines can be pushed into and pulled out of the installation cavity structure in a drawer-like manner (plug and play). After the multiple sub-machines are inserted, they share the air duct. Exemplarily, the sub-machines at least include a HEPA filter screen device, an ion generator device, a humidifying device, or an oxygen generating device. The HEPA filter screen device is used to remove fine particulate matter (including fine particulate matter with a diameter of less than 2.5 microns) in the air. The ion generator device generates negative ions by using a high-voltage transformer to step up the power frequency voltage to the required voltage and releases the negative ions into the air to purify the air. The humidifying device can increase the moisture content in the air to make the air humid. The oxygen generating device can increase the oxygen content in the air to increase the oxygen content of the blood of the human body when breathing, so that the human body is in a better mental state.

[0036] As shown in FIG. 3, the specific steps of the information interaction method can include: Figure 1

[0037] Step 101: When it is determined that the sub-machine is installed in place on the main machine, and it is determined that the output voltage and the output current of any one of the communication sockets meet the communication condition when the first communication socket and the second communication socket are connected, the main machine sends a first instruction to the sub-machine through the information transmission line composed of the first communication socket and the second communication socket.

[0038] Here, the first socket on the main machine includes the first communication socket, and the second socket on the sub-machine includes the second communication socket.

[0039] ​It should be noted that when the first communication socket on the host is connected with the second communication socket on the slave machine, there is a contact resistance (including a shrinkage resistance and a film layer resistance) at the connecting contact. After a long time of plugging and unplugging operation, the connecting contact will be deformed, and it can also be oxidized due to environmental pollution, resulting in an increase in the contact resistance, and a situation that the film layer resistance cannot be broken through can occur, thereby causing a situation of information interaction failure. In order to avoid the situation of information interaction failure, the present application determines whether the output voltage and the output current of the first communication socket or the second communication socket satisfy the communication condition when the first communication socket is connected with the second communication socket after the slave machine is installed in place on the host, and determines that the film layer resistance is directly broken through when the first communication socket is connected with the second communication socket when the communication condition is satisfied, so as to ensure that the host and the slave machine can interact information. Conversely, when the communication condition is not satisfied, the film layer resistance cannot be broken through when the first communication socket is connected with the second communication socket, that is, the host and the slave machine cannot interact information.

[0040] In some embodiments, the first socket further comprises a first power supply socket, and the second socket further comprises a second power supply socket; the first communication socket is connected with the first voltage and current detection module, and the second communication socket is connected with the second voltage and current detection module; after the slave machine is installed in place on the host, the method further comprises: controlling the host to supply power to the slave machine through the first power supply socket and the second power supply socket; controlling the host to send a first self-check signal to the first voltage and current detection module, and detecting whether the output voltage and the output current of the first communication socket satisfy the communication condition by using the first voltage and current detection module; or, controlling the slave machine to send a second self-check signal to the second voltage and current detection module, and detecting whether the output voltage and the output current of the second communication socket satisfy the communication condition by using the second voltage and current detection module.

[0041] That is, the first voltage and current detection module is installed on the host side, and whether the output voltage and the output current of the first communication socket satisfy the communication condition is detected by using the first voltage and current detection module. When the communication condition is satisfied, it is indicated that the host and the slave machine can interact information. Here, the host can send instruction information (i.e., the first instruction mentioned above) to the slave machine through the information transmission line composed of the first communication socket and the second communication socket.

[0042] Or, the second voltage and current detection module is installed on the slave machine side, and whether the output voltage and the output current of the second communication socket satisfy the communication condition is detected by using the second voltage and current detection module. When the communication condition is satisfied, it is indicated that the host and the slave machine can interact information. Here, the host can send instruction information (i.e., the first instruction mentioned above) to the slave machine through the information transmission line composed of the first communication socket and the second communication socket.

[0043] For example, when the slave machine is an oxygen generating device, the first instruction can be an oxygen generating instruction.

[0044] In some embodiments, the communication condition comprises: the output voltage of the first communication jack is greater than a preset voltage threshold value, and the output current is greater than a preset current threshold value; or, the output voltage of the second communication jack is greater than a preset voltage threshold value, and the output current is greater than a preset current threshold value.

[0045] Here, the preset voltage threshold value is a voltage allowable value of the contact resistance, and the preset current threshold value is a current allowable value of the contact resistance.

[0046] That is, the output voltage of the first communication jack is greater than a preset voltage threshold value, and the output current is greater than a preset current threshold value, or, the output voltage of the second communication jack is greater than a preset voltage threshold value, and the output current is greater than a preset current threshold value, the first communication jack and the second communication jack are in contact with the film layer resistance, and the normal interaction of information between the host and the slave is ensured.

[0047] In some embodiments, the output end of the host is connected with the first voltage and current detection module in series, and the output end of the slave is connected with the second voltage and current detection module in series; wherein the first voltage and current amplification module is used to amplify the output voltage and the output current of the host, so that the output voltage of the first communication jack is greater than a preset voltage threshold value, and the output current of the first communication jack is greater than a preset current threshold value; the second voltage and current amplification module is used to amplify the output voltage and the output current of the slave, so that the output voltage of the second communication jack is greater than a preset voltage threshold value, and the output current of the second communication jack is greater than a preset current threshold value.

[0048] In practical application, because the output voltage and the output current of the host, and the output voltage and the output current of the slave are too low to break through the film layer resistance, the first voltage and current amplification module is connected to the output end of the host, and the second voltage and current amplification module is connected to the output end of the slave, so as to use the first voltage and current amplification module to amplify the output voltage of the host to be greater than a preset voltage threshold value and to amplify the output current of the host to be greater than a preset current threshold value, and use the second voltage and current amplification module to amplify the output voltage of the slave to be greater than a preset voltage threshold value and to amplify the output current of the slave to be greater than a preset current threshold value, so that the first communication jack and the second communication jack are in contact with the film layer resistance, so as to ensure that the host and the slave can interact information.

[0049] Step 102: the slave generates response information in response to the first instruction, and controls the host to receive the response information sent by the slave through the information transmission line.

[0050] In some embodiments, the communication mode of the information transmission line is a single-wire half-duplex communication mode.

[0051] It should be noted that the general information interaction includes 4 lines, namely the VCC power line, the RXD receiving line, the TXD sending line and the GND ground line, the more signal bits, the more the structure design and installation errors affect the possibility of alignment failure of the socket. In order to reduce the risk of alignment failure, the RXD receiving line, the TXD sending line and the GND ground line are shared in one line, that is, the information interaction is adjusted from 4 lines to 2 lines (including the power supply socket and the communication socket), so as to reduce the risk of alignment failure. Among them, the power supply socket and the communication socket can be set as single-hole alignment, and can also be set as spring type, magnetic type docking.

[0052] Specifically, the host and the slave machine are set to adopt a single-wire half-duplex communication mode, which refers to a single-wire half-duplex communication mode that can switch direction, that is, the host to the slave machine (corresponding to step 101) and the slave machine to the host (corresponding to step 102) are both based on a single-wire half-duplex communication mode to send information through the same information transmission line.

[0053] For example, when the slave machine is an oxygen generating device and the first instruction is an oxygen generating instruction, the host sends the oxygen generating instruction to the slave machine until the slave machine responds to the oxygen generating instruction, and the slave machine sends the response information corresponding to the oxygen generating instruction to the host through the information transmission line. When the host receives the response information, the host stops sending the oxygen generating instruction to the slave machine. When the first instruction is a stop instruction, the host sends the stop instruction to the slave machine, the slave machine responds to the stop instruction, and the slave machine sends the stop information to the host through the information transmission line. When the host receives the stop information, the host stops supplying power to the slave machine.

[0054] Here, the execution subject of steps 101 to 102 can be the processor of the information interaction device.

[0055] By using the above technical solution, when the first communication socket on the host and the second communication socket on the slave machine are in contact and the output voltage and current of any communication socket meet the communication condition, it is ensured that the information transmission line composed of the first communication socket and the second communication socket is in a conduction state, and the information interaction between the host and the slave machine can be successfully realized, avoiding the information interaction failure caused by the connection failure of the host and the slave machine.

[0056] The above embodiments point out that due to the low voltage and current at the output terminals of the host and sub-machine, the contact resistance may not be broken down, resulting in the failure of information exchange. The present application installs corresponding voltage and current amplification modules on both the host and sub-machine. It also points out that in order to ensure the correct information exchange, by installing corresponding voltage and current detection modules on either the host or the sub-machine, the correctness of the information exchange between the host and the sub-machine can be guaranteed when the voltage and current detection modules are used to detect that the output voltage and output current of the communication socket meet the communication conditions. In this regard, the present application provides a first voltage and current amplification circuit for the first voltage and current amplification module on the host, and a second voltage and current amplification circuit for the second voltage and current amplification module on the sub-machine. Figure 3 This is a schematic diagram of the structure of the first voltage-current amplifier circuit and the second voltage-current amplifier circuit in the embodiment of the present application, wherein: Figure 3 In the embodiment, a first voltage and current detection module is installed on the host, or a second voltage and current detection module is installed on the slave (schematic diagram is not shown here).

[0057] Here, before the circuit structure is specifically described, it should be noted that in the above embodiment, the RXD receiving line, the TXD transmitting line and the GND ground line are on the same line, that is, they share a communication socket, corresponding to Figure 3 The CN1 end of the host (i.e. the first communication socket) and the CN2 end of the slave (i.e. the second communication socket).

[0058] like Figure 3 As shown, taking the first output voltage of the host as 5V and the second output voltage of the slave as 5V as an example, they are amplified to 12V by the first voltage-current amplifying circuit and the second voltage-current amplifying circuit respectively, and the current in the circuit is also amplified. The first voltage-current detection module is used to detect that the amplified voltage of 12V is greater than the preset voltage threshold at the connecting contact between CN1 and CN2, and the amplified current is greater than the preset current threshold at the connecting contact between CN1 and CN2, so the membrane resistance can be directly broken down to achieve normal information interaction between the host and the slave.

[0059] The first voltage and current amplifying circuit corresponding to the host includes a first sub-circuit (i.e., an information receiving circuit) and a second sub-circuit (i.e., an information sending circuit); the second voltage and current amplifying circuit corresponding to the slave includes a third sub-circuit (i.e., an information receiving circuit) and a fourth sub-circuit (i.e., an information sending circuit); that is, when the host sends information to the slave, the host sends the information via the second sub-circuit, and the slave receives the information via the third sub-circuit; when the slave sends information to the host, the slave sends the information via the fourth sub-circuit, and the host receives the information via the first sub-circuit.

[0060] Specifically, the first sub-circuit is a corresponding circuit when the host receives information sent by the slave, and specifically comprises resistors R10, R14, R15, R16, transistors NPN5, NPN6 and a diode D4, and is connected in the following manner: the negative electrode of D4 is connected to the 1 port of CN1 through the first voltage and current detection module, the positive electrode of D4 is connected to the collector of NPN5 through R10, the emitter of NPN5 is grounded through R16, the base of NPN5 is connected to a 5V output voltage through R14, the collector of NPN6 is connected to a 5V output voltage through R15 and is also connected to KT-RXD (i.e. a receiving information port), the base of NPN6 is connected to the emitter of NPN5, and the emitter of NPN6 is grounded.

[0061] The second sub-circuit is a corresponding circuit when the host sends information to the slave, and specifically comprises resistors R9, R11, R12, R13, transistors NPN4, PNP2 and a diode D3, and is connected in the following manner: the negative electrode of D3 is connected to the 1 port of CN1 through the first voltage and current detection module, the positive electrode of D3 is connected to the collector of PNP2 through R9, the emitter of PNP2 is connected to a 12V voltage source and is also connected to its base through R11, the base of PNP2 is connected to the collector of NPN4 through R12, the base of NPN4 is connected to a 5V output voltage through R13, and the emitter of NPN4 is connected to KT-TXD (i.e. a sending information port).

[0062] The third sub-circuit is a corresponding circuit when the slave receives information sent by the host, and specifically comprises resistors R5, R6, R7, R8, transistors NPN2, NPN3 and a diode D2, and is connected in the following manner: the negative electrode of D2 is connected to the 1 port of CN1, the positive electrode of D2 is connected to the collector of NPN2 through R5, the emitter of NPN2 is grounded through R7, the base of NPN2 is connected to a 5V output voltage through R6, the collector of NPN3 is connected to a 5V output voltage through R8 and is also connected to ZY-RXD (i.e. a receiving information port), the base of NPN3 is connected to the emitter of NPN2, and the emitter of NPN3 is grounded.

[0063] The fourth sub-circuit is a corresponding circuit when the slave sends information to the host, and specifically comprises resistors R1, R2, R3, R4, transistors NPN1, PNP1 and a diode D1, and is connected in the following manner: the negative electrode of D1 is connected to the 1 port of CN1, the positive electrode of D1 is connected to the collector of PNP1 through R4, the emitter of PNP1 is connected to a 12V voltage source and is also connected to its base through R3, the base of PNP1 is connected to the collector of NPN1 through R2, the base of NPN1 is connected to a 5V output voltage through R1, and the emitter of NPN1 is connected to ZY-TXD (i.e. a sending information port).

[0064] It should be noted that, Figure 3The first voltage and current amplification circuit and the second voltage and current amplification circuit shown in the above embodiment are only example circuits, and other circuits capable of achieving the above functions can also be used.

[0065] Based on the above embodiment, the application further provides an information interaction method, Figure 4 FIG. 2 is a second flowchart of the information interaction method in the embodiment of the application.

[0066] As shown in Figure 4 The information interaction method is applied to an air conditioner, the air conditioner includes a host and a slave, the host includes a first socket, and the slave includes a second socket corresponding to the first socket; the information interaction method can include the following steps:

[0067] In step 401, when the host receives a second instruction, the host detects whether the slave is installed in place on the host in response to the second instruction.

[0068] Here, the second instruction is a detection instruction. For example, the host receives the detection instruction by clicking a detection button on a terminal application (APP), clicking a detection button on a remote control panel of the host, or clicking a detection button on the host.

[0069] Here, after the host receives the detection instruction, to avoid the host directly supplying power to the slave and other operations when the slave is not installed in place, which can cause unsafe problems, the host needs to first detect whether the slave is installed in place on the host.

[0070] To solve the problem of how to detect whether the slave is installed in place on the host, in some embodiments, the host further includes a first switch and a second switch, an open and close state of the first switch represents whether the slave is covered by a panel on the host, and an open and close state of the second switch represents whether the slave is inserted into a mounting cavity of the host; the detection of whether the slave is installed in place on the host includes: detecting whether the first switch and the second switch are both in a closed state; if both are in the closed state, it is determined that the slave is installed in place on the host; if any one of the switches is in an open state, it is determined that the slave is not installed in place on the host.

[0071] That is, the open and close states of the panel switch covering the slave on the host and the second switch in the mounting cavity of the host are detected; if the panel switch is detected to be in an open state and the second switch is detected to be in a closed state, a child can pull out the slave due to curiosity, at this time, the slave is in an electrified state, and sparks are easy to be generated when the slave is directly pulled out, which can cause electric shock and is very unsafe; if the second switch is detected to be in an open state, at this time, the panel switch is in either a closed state or an open state, and the slave is not inserted into the mounting cavity of the host; therefore, only when the panel switch and the second switch are both in the closed state, the slave is installed in place on the host and there is no unsafe problem.

[0072] The setting for the first switch (for example, a panel switch), Figure 2 The middle and lower expansion function component includes a panel and a chassis, and the panel switch is installed on the chassis. For example, the panel switch can be a magnetic control switch or a button switch.

[0073] The setting for the second switch. For example, the application provides an external structure diagram of a sub-machine (for example, an oxygen generating device), Figure 5 The external interface of the oxygen generating device is shown in the schematic diagram of the external interface of the oxygen generating device in the embodiments of the application. As shown in the figure, the external interface of the oxygen generating device includes an air flow interface, a positioning contact, a power input (that is, a second power supply socket), and an information interaction (that is, a second communication socket). Figure 5

[0074] The positioning contact refers to a magnetic assembly that can be recognized by the magnetic control switch (that is, the second switch) or a mechanical assembly that can push the button switch (that is, the second switch). The magnetic control switch or the button switch used in cooperation with the positioning contact is installed in the oxygen generating device installation cavity on the main machine. The air flow interface includes an air inlet, an oxygen outlet, and a nitrogen outlet. After the oxygen generating device is installed in the air conditioner, the air inlet of the oxygen generating device is in communication with the upper and lower air ducts of the lower expansion function component of the air conditioner. After the air inlet valve of the lower air duct is opened, air reaches the air inlet of the oxygen generating device through the upper and lower air ducts. The oxygen outlet of the oxygen generating device is in communication with the air outlet of the lower expansion function component, and oxygen can be discharged to the indoor environment through the air outlet. The nitrogen outlet pipeline is also pre-buried on the lower expansion function component, and the nitrogen outlet pipeline extends to the outdoor environment. After the oxygen generating device is installed in the air conditioner, the nitrogen outlet is directly connected to the pre-buried nitrogen outlet pipeline of the air conditioner to discharge nitrogen to the outdoor environment.

[0075] Step 402: determining whether the output voltage and the output current of any one of the first communication socket and the second communication socket meet the communication condition when the sub-machine is installed in place on the main machine and the first communication socket is connected to the second communication socket;

[0076] Here, the first socket includes the first communication socket, and the second socket includes the second communication socket.

[0077] In some embodiments, the first socket further includes a first power supply socket, and the second socket further includes a second power supply socket. The first communication socket is connected to the first voltage and current detection module, and the second communication socket is connected to the second voltage and current detection module. After the sub-machine is installed in place on the main machine, the method further includes: controlling the main machine to supply power to the sub-machine through the first power supply socket and the second power supply socket; controlling the main machine to send a first self-check signal to the first voltage and current detection module, and using the first voltage and current detection module to detect whether the output voltage and the output current of the first communication socket meet the communication condition; or, controlling the sub-machine to send a second self-check signal to the second voltage and current detection module, and using the second voltage and current detection module to detect whether the output voltage and the output current of the second communication socket meet the communication condition. ​

[0078] In some embodiments, the communication condition comprises: the output voltage of the first communication socket is greater than a preset voltage threshold, and the output current is greater than a preset current threshold; or, the output voltage of the second communication socket is greater than a preset voltage threshold, and the output current is greater than a preset current threshold.

[0079] In some embodiments, a first voltage and current amplification module is connected in series between the output end of the host and the first voltage and current detection module, and a second voltage and current amplification module is connected in series between the output end of the slave and the second voltage and current detection module; wherein the first voltage and current amplification module is configured to amplify the output voltage and the output current of the host, so that the output voltage of the first communication socket is greater than a preset voltage threshold, and the output current of the first communication socket is greater than a preset current threshold; the second voltage and current amplification module is configured to amplify the output voltage and the output current of the slave, so that the output voltage of the second communication socket is greater than a preset voltage threshold, and the output current of the second communication socket is greater than a preset current threshold.

[0080] Step 403: When the communication condition is met, the host is controlled to send a first instruction to the slave through the information transmission line composed of the first communication socket and the second communication socket.

[0081] In actual application, when the first communication socket and the second communication socket meet the communication condition, the host is controlled to send the first instruction to the slave through the information transmission line according to a preset time period, and the host stops sending the first instruction to the slave until the slave receives and responds to the oxygen production instruction.

[0082] Step 404: The slave generates response information in response to the first instruction, and the host is controlled to receive the response information sent by the slave through the information transmission line.

[0083] In some embodiments, the communication mode of the information transmission line is a single-wire half-duplex communication mode.

[0084] For example, when the slave is an oxygen production device and the first instruction is an oxygen production instruction, the slave responds to the oxygen production instruction, controls the slave to send the response information corresponding to the oxygen production instruction to the host through the information transmission line, and the host stops sending the oxygen production instruction to the slave.

[0085] For example, if the response information is fault information, the host stops supplying power to the slave and sends an alarm information to prompt the user that the slave has a fault.

[0086] In some embodiments, the method further comprises: when the host receives a shutdown instruction or detects that the first switch is in an open state, the host is controlled to send the shutdown instruction to the slave through the information transmission line; the slave responds to the shutdown instruction and returns corresponding shutdown information to the host through the information transmission line; and the host is controlled to control the slave to be in an inoperative state based on the shutdown information.

[0087] Here, the sub-machine is taken as an example of the oxygen generating device, the host machine receives the stop command, which may be because the host machine sends the oxygen concentration query command to the sub-machine through the information transmission line, the sub-machine returns the current oxygen concentration in the air to the host machine through the information transmission line, the host machine detects that the oxygen concentration in the air reaches the threshold value, and sends an alarm information to prompt the user to click the oxygen generating stop button on the terminal APP, click the oxygen generating stop button on the remote control panel of the host machine, or click the oxygen generating stop button on the host machine, so that the host machine receives the stop command. The host machine sends the received stop command to the sub-machine, and after the sub-machine stops generating oxygen in response to the stop command, the host machine stops supplying power to the sub-machine, so that the sub-machine is in an inactive state.

[0088] Alternatively, when it is detected that the panel switch (i.e. the first switch) is in an open state, there is an unsafe problem, so the host machine also needs to send a stop command to the sub-machine through the information transmission line, and after the sub-machine stops generating oxygen in response to the stop command, the host machine stops supplying power to the sub-machine, so that the sub-machine is in an inactive state. The above-mentioned way of controlling the sub-machine to be in an inactive state can prolong the service life of the sub-machine compared with the way of directly stopping the power supply to the sub-machine after the host machine receives the stop command.

[0089] By adopting the above technical solution, when the output voltage and current of any communication socket meet the communication condition, it is ensured that the information transmission line composed of the first communication socket and the second communication socket is in a conduction state, and the information interaction between the host machine and the sub-machine can be successfully realized, avoiding the information interaction failure caused by the connection failure of the host machine and the sub-machine.

[0090] Based on the above embodiment, the host machine is taken as an example of the air conditioner, and the sub-machine is taken as an example of the oxygen generating device, and a control structure diagram of the oxygen generating device is given, Figure 6 The control structure diagram of the oxygen generating device in the embodiment of the present application is shown in FIG. 1.

[0091] As Figure 6As shown, when the air conditioner 61 receives the detection instruction, the control detection component 614 detects whether the first switch and the second switch in the above embodiment are both in the closed state. When both are in the closed state, the air conditioner control board 615 receives the relevant instruction information, controls the opening and closing of the air inlet and outlet valve assembly 618, controls the on-off of the high-power switching power supply module 610 through the relay driving circuit 616, and after the high-power switching power supply module 610 is turned on and off, the air conditioner 61 cannot supply power to the oxygen generating device 60 through the first power supply socket 612 in the oxygen generating load interface board 611 and the second power supply socket 606 in the oxygen input interface 605, that is, the oxygen generating device 60 is turned on and off. After the oxygen generating device 60 is powered on, it waits to receive the oxygen generating start instruction sent by the air conditioner 61 through the first communication socket 613 and the second communication socket 607. After receiving the oxygen generating start instruction, the oxygen generating device 60 controls the oxygen generating core component 601 to work and start oxygen generation. After receiving the fault or oxygen concentration query information, the oxygen generating device 60 returns the information queried by the air conditioner 61 in advance. After receiving the shutdown instruction, the oxygen generating device 60 controls the oxygen generating core component 601 to execute the shutdown operation and then sends the shutdown information to the air conditioner 61. The air conditioner 61 controls the oxygen generating device 60 to be powered off and closes the air inlet valve assembly 618. Among them, the first voltage and current amplification circuit 617 pre-adjusts the output voltage of the first communication socket 613, and the second voltage and current amplification circuit 604 pre-adjusts the output voltage of the second communication socket 607. When the first communication socket 613 and the second communication socket 607 are in contact, the membrane resistance between the communication contacts can be directly broken down to realize the information interaction between the oxygen generating device 60 and the air conditioner 61. Figure 6 The voltage and current detection module is not shown in the embodiment, and can be connected in series between the first communication socket 613 and the first voltage and current amplification circuit 617, or can be connected in series between the second communication socket 607 and the second voltage and current amplification circuit 604.

[0092] Based on the above embodiment, the application also provides an information interaction method, Figure 7 The third flowchart of the information interaction method in the embodiment of the application is shown.

[0093] As Figure 7 shown, the information interaction method is applied to an air conditioner, which includes a host and a slave. The host includes a first socket, and the slave includes a second socket corresponding to the first socket. The information interaction method can include the following steps:

[0094] Step 701: When the slave is installed in place on the host, the host supplies power to the slave through the first power supply socket and the second power supply socket.

[0095] Here, the first socket includes a first power supply socket, and the second socket includes a second power supply socket.

[0096] In some embodiments, the host further comprises a first switch and a second switch, the open / close state of the first switch representing whether the sub-device is covered by the upper panel of the host, and the open / close state of the second switch representing whether the sub-device is inserted into the installation cavity of the host; when both the first switch and the second switch are detected to be in the closed state, it is determined that the sub-device is installed in place on the host, i.e., the sub-device is inserted into the host, and at this time the host can supply power to the sub-device through the first power supply socket and the second power supply socket.

[0097] Step 702: control the electric suction device to be in the closed state to ensure that the sub-device cannot be pulled out of the host in the case of live electricity;

[0098] In some embodiments, the host further comprises an electric suction device, and the sub-device further comprises a suction head corresponding to the electric suction device; or the sub-device further comprises an electric suction device, and the host further comprises a suction head corresponding to the electric suction device.

[0099] Here, in view of the unsafe problems of strong electricity plug-in, such as sparks and electric shock, the electric suction device is arranged on the host, and the suction head is arranged on the sub-device, or the electric suction device is arranged on the sub-device, and the suction head is arranged on the host, so that the electric suction device is in the closed state when the sub-device is live, and cannot be pulled out of the host, to ensure safety.

[0100] Step 703: when the output voltage and output current of any one of the first communication socket and the second communication socket connected to each other meet the communication condition, control the host to send a first instruction to the sub-device through the information transmission line composed of the first communication socket and the second communication socket according to a preset time period;

[0101] Here, the first socket comprises the first communication socket, and the second socket comprises the second communication socket.

[0102] Here, when the output voltage and output current of any one of the first communication socket and the second communication socket connected to each other meet the communication condition, i.e., the host and the sub-device can exchange information, the host can send the first instruction to the sub-device through the information transmission line according to the preset time period until the sub-device receives the first instruction and responds to the first instruction. Otherwise, the host needs to send the first instruction to the sub-device according to the preset time period.

[0103] The above-mentioned preset time period can be set by artificial experience or obtained by experiment.

[0104] Step 704: the sub-device generates response information in response to the first instruction, and controls the host to receive the response information sent by the sub-device through the information transmission line.

[0105] In some embodiments, the communication mode of the information transmission line is a single-wire half-duplex communication mode.

[0106] In some embodiments, if the response information is fault information or shutdown information, the method further comprises: controlling the host to stop supplying power to the slave machine via the first power supply socket and the second power supply socket.

[0107] In actual application, the host sends a fault query instruction to the slave machine via the information transmission line, the slave machine returns fault information to the host via the information transmission line, and the host stops supplying power to the slave machine via the first power supply socket and the second power supply socket. Alternatively, the host sends a shutdown instruction to the slave machine via the information transmission line, the slave machine returns shutdown information to the host via the information transmission line, and the host stops supplying power to the slave machine via the first power supply socket and the second power supply socket.

[0108] In some embodiments, after stopping supplying power to the slave machine, the method further comprises: the slave machine performs a discharging operation, and when it is determined that the discharging time of the slave machine is greater than a preset time threshold, controlling the electrically operated attraction device to be in an open state.

[0109] Here, the preset time threshold can be understood as the average discharging time of the slave machine. After the host stops supplying power to the slave machine, the slave machine starts discharging. When the discharging time is greater than the preset time threshold, it indicates that the slave machine is not electrified at this time, and the electrically operated attraction device is controlled to be in an open state, ensuring that the slave machine can be safely pulled out of the host in the case of power failure. Conversely, if the slave machine has not completed discharging, i.e., the slave machine is electrified at this time, the electrically operated attraction device is controlled to be in a closed state, so that the slave machine cannot be pulled out of the host, avoiding the risk of electric shock when the slave machine is pulled out of the host in the case of electrification.

[0110] By using the above technical solution, when the output voltage and current of any communication socket meet the communication condition, it is ensured that the information transmission line composed of the first communication socket and the second communication socket is in a conductive state, and the information interaction between the host and the slave machine can be successfully realized, avoiding information interaction failure caused by connection failure of the host and the slave machine.

[0111] To implement the method of the embodiments of the present application, based on the same inventive concept, the embodiments of the present application also provide an information interaction device, Figure 8 For the structural schematic diagram of the information interaction device in the embodiments of the present application, as shown in Figure 8 The information interaction device is applied to an air conditioner, the air conditioner includes a host and a slave machine, the host includes a first socket, and the slave machine includes a second socket corresponding to the first socket; the first socket includes a first communication socket, and the second socket includes a second communication socket; the information interaction device includes:

[0113] The control unit 802 is configured to control the host machine to receive the response information sent by the slave machine through the information transmission line in response to the first instruction.

[0114] By using the above technical solution, when the first communication jack of the host machine and the second communication jack of the slave machine are in contact, and the output voltage and the output current of any one of the communication jacks satisfy the communication condition, it is ensured that the information transmission line composed of the first communication jack and the second communication jack is in a conduction state, and the information interaction between the host machine and the slave machine can be successfully realized, and the information interaction failure caused by the connection failure of the host machine and the slave machine is avoided.

[0120] In the embodiment, the purpose of arranging the electrically-driven suction device is to ensure that the electrically-driven suction device is in the closed state in the live condition of the slave, so that the slave cannot be pulled out of the host, thereby ensuring the safety of power utilization.

[0121] In some embodiments, if the response information is fault information or shutdown information, the host is controlled to stop supplying power to the slave through the first power supply jack and the second power supply jack.

[0122] In some embodiments, after the slave stops being supplied with power, the slave performs a discharging operation, and when it is determined that the discharging time of the slave is greater than a preset time threshold, the electrically-driven suction device is controlled to be in an open state.

[0123] In the embodiment, after the slave completes discharging, the electrically-driven suction device is in the open state, so that the slave can be safely pulled out of the host.
