[0026] Figure 1 It is a schematic diagram of the detection structure of an ion blower without a high-voltage electrode cartridge installed. Figure 2 It is a schematic diagram of the usage state of the detection structure of an ion blower without a high-voltage electrode cartridge installed. Figure 3 It is Figure 2Schematic diagram of the enlarged part, including the first PCB board 4, on which a mesh cover connection thimble 7, a detection negative thimble 5, and a detection positive thimble 6 are installed. It also includes a main control PCB board 3. Combining Figure 3 , the main control PCB board 3 is provided with a mesh cover thimble connection port 304, a negative thimble connection port 302, and a positive thimble connection port 303. The mesh cover connection thimble 7 can be connected to the mesh cover thimble connection port 304 to detect whether the mesh cover is installed. The detection negative thimble 5 can be connected to the negative thimble connection port 302, and the detection positive thimble 6 can be connected to the positive thimble connection port 303 to detect whether the electrode cartridge is installed.

[0027] A thimble mounting block is provided on the first PCB board 4. The mesh cover connection thimble 7, the detection negative thimble 5, and the detection positive thimble 6 are all installed on the thimble mounting block. The three thimbles are first installed on the thimble mounting block, and then the thimble mounting block is installed on the first PCB board 4, so that the first PCB board 4 and the three thimbles form a whole module, which is convenient for installation into the mesh cover 2.

[0028] The main control PCB board 3 is provided with a thimble connection end face 301. The mesh cover thimble connection port 304, the negative thimble connection port 302, and the positive thimble connection port 303 are all arranged on the thimble connection end face 301. A special end face is provided on the main control PCB board 3 for the thimble connection port, and this end face is arranged on the side of the main control PCB board 3. After the main control PCB board 3 is installed, this end face can be exposed for easy connection with the thimble.

[0029] The main control PCB board 3 is also provided with a positive high-voltage connection thimble 8 and a negative high-voltage connection thimble 9.

[0030] The first PCB board 4 is installed on the mesh cover 2, and the main control PCB board 3 is installed on the electrode cartridge 1.

[0031] The utility model also includes a detection circuit. As Figure 4 shown, the first box from left to right represents the metal mesh cover, the second box represents the first PCB board 4, the third box represents the three thimbles, the fourth box represents the main control PCB board 3, the fifth box represents the high-voltage generation module, GND below represents the mesh cover connection thimble 7, GND above represents the detection negative thimble 5, and the XH1 port represents the detection positive thimble 6. Among them, the main control PCB board 3 includes a main control MCU. The MCU accesses the XH1 port as a detection signal port. The XH1 port is provided with a pull-up resistor R1. The MCU outputs a high-voltage control signal to the high-voltage generation module. The high-voltage generation module has a positive high-voltage output port and a negative high-voltage output port.

[0032] When the electrode cartridge is properly installed, the current of the XH1 port is connected to the pin mounting PCB of the electrode cartridge, i.e., the first PCB board 4, through the detection positive electrode pin 6, and returns and shorts to the ground terminal through the detection negative electrode pin 5. The XH1 is at a low level, and the MCU controls the operation of the high-voltage generation module. When the electrode cartridge is not installed or is installed poorly, the XH1 terminal is floating. Due to the pull-up effect of the resistor R1, the input of the XH1 port is at a high level, and the control signal for shutting down the high-voltage generation module output by the MCU causes the high-voltage generation module not to work, thus avoiding safety accidents of electric shock to the human body and protecting other control circuits from high-voltage discharge.

[0033] The above description is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention all fall within the scope of the technical solution of the present invention.
