Handheld inkjet printers are flexible, easy to use, and easy to move. They are suitable for occasions where products need to be changed frequently or coding needs to be performed at different locations. Handheld inkjet printers usually use inkjet technology to spray ink or solvent ink onto the surface of the object through a nozzle to complete the marking.

[0003] For example, the application with the publication number CN215883035U discloses a printer head, the printer head includes two nozzles, the nozzle includes a gun body and a nozzle plate, the nozzle plate is installed at the front end of the gun body, an inkjet pipeline is arranged in the nozzle plate, the inkjet pipeline forms a first spray hole opening on the lower surface of the nozzle plate, the inkjet pipeline forms a second spray hole opening on the upper surface of the nozzle plate, the two nozzles are arranged side by side, the distance between the centers of the second spray hole openings of the two nozzles is greater than the distance between the centers of the first spray hole openings of the two nozzles, and the distance between the centers of the first spray hole openings of the two nozzles is less than or equal to 4mm. The printer head of the embodiment of the utility model has a low degree of dependence on the position tracking sensor, the matching error of the two nozzles is greatly reduced, and the printing effect is significantly improved.

[0004] However, in this application, the inkjet printer nozzle cannot be disassembled and replaced, which is not conducive to inkjet coding applications in various scenarios and cleaning of the nozzle, and can easily cause blockage. Utility Model Content

[0005] The purpose of this application is to provide a portable replaceable inkjet printer nozzle for chemical applications in order to solve the problem that the inkjet printer nozzle cannot be disassembled and replaced, which is not conducive to inkjet coding applications in various scenarios and cleaning of the nozzle, and is prone to clogging.

[0006] The technical solution adopted in the present application is as follows: A portable replaceable inkjet printer nozzle for chemical application, comprising a device housing, a limiting slot fixedly connected to the inner surface of the device housing, an inkjet body fixedly connected to the inner surface of the device housing, an inkjet port fixedly connected to the outer surface of the inkjet body, a positioning plate movably connected to the inner surface of the limiting slot, a thin film resistor plate provided on the inner surface of the positioning plate, an adsorption pad fixedly connected to the outer surface of the positioning plate, an inkjet plate fixedly connected to the outer surface of the adsorption pad at one end away from the positioning plate, a side protective plate fixedly connected to the outer surface of the inkjet plate at one end away from the adsorption pad, and a guide strip fixedly connected to the outer surface of the inkjet plate next to the side protective plate.

[0007] By adopting the above technical solution, when in use, the ink cartridge of the device delivers ink to the inkjet body through the ink delivery body through the conduit. The inkjet body is divided into three independent delivery pumps, upper, middle and lower. They can be used separately to output small fonts for coding, or they can be used together to complete the coding of fonts with higher font heights. Similarly, the coding of graphics of different heights can be completed. The positioning plate, inkjet plate, and adsorption pad constitute the nozzle as a whole. The protective cover is inserted obliquely into the corresponding limit slot position after taking out the ink cartridge, and the telescopic motor is turned on to complete the forward push, so that the inner surface of the positioning plate corresponds to the inkjet port. Each time the coding is sprayed, the telescopic motor is pushed forward twice to send the nozzle at the front end of the inkjet plate to the front end of the inkjet port. The positioning plate is quickly heated as a whole to form a large number of bubbles, and the inkjet port quickly sprays ink Water, corresponding to the smaller outer surface outlet of the inkjet plate, is sprayed to the surface to be coded by inertia to complete the spraying. When the spraying is completed, the deformation of the limit card slot will return the nozzle to the corresponding position of the inkjet port and the positioning plate, waiting for the next output. The middle adsorption pad adopts a highly absorbent resin material to absorb the fallen ink to avoid contaminating the functional area and affecting the coding effect. The side protection plate ensures the stability of the ink airflow for coding, so that the ink is released forward. The guide strip will prevent the ink hanging on the surface of the inkjet plate from being guided to the outer surface of the side protection plate to avoid affecting other nozzles. When outputting small fonts for coding, three output ends can be used for coding, which reduces the frequency of nozzle replacement, ensures the use effect of the equipment, and is convenient to remove for cleaning.

[0009] By adopting the above technical solution, the telescopic motor is set with three telescopic areas. The innermost retracted state can be used to take out and replace the nozzle, the middle state is the standby and normal use state, and the forward extension state is the state for coding. The raised block moves the dustproof plate left and right on the inner surface of the device casing through the left and right displacement of the hand. The device is turned off when not in use to prevent the outer surface of the nozzle from contacting with external dust and causing blockage.

[0010] In a preferred embodiment, reference wheels are arranged on both sides of the outer surface of the device housing corresponding to the protruding block, the outer surface of the reference wheel is movably connected to a rubber rope, and the outer surface of the rubber rope away from the reference wheel is movably connected to a passive wheel.

[0011] By adopting the above technical solution, the reference wheel ensures the stability of the coding, and is displaced on the surface to be sprayed to ensure the stable output of the equipment. The displacement of the reference wheel provides rotation for the passive wheel through the rubber rope, and the result is transmitted to the distance measuring body.

[0012] In a preferred embodiment, a distance measuring body is provided on the outer surface of the passive wheel, a control body is fixedly connected to the outer surface of the distance measuring body corresponding to the inside of the device housing, and an ink cartridge connecting body is fixedly connected to the outer surface of the control body.

[0013] By adopting the above technical solution, the distance measuring body enables the device to obtain the parameters of the output distance through the rotation of the passive wheel, so that the device can output the inkjet code at the corresponding position. The control body is the control unit of the entire device, ensuring the mutual coordination of various components. The ink cartridge connecting body supports the ink cartridge and the corresponding device is connected to it at the same time.

[0014] In a preferred embodiment, a power cord is fixedly connected to the outer surface of the control body, a handle is fixedly connected to the outer surface of the device housing, and a trigger switch is provided on the outer surface of the handle.

[0017] By adopting the above technical solution, the ink supplying body supplies the ink of the ink cartridge to the ink jetting body through the conduit to perform coding.

[0018] In a preferred embodiment, an ink cartridge is movably connected to the outer surface of the ink delivery body, and a protective cover is movably connected to the outer surface of the device housing corresponding to the ink cartridge.

[0019] By adopting the above technical solution, the ink cartridge is the main ink supply accessory. Through the limitation of the inside of the device shell and the ink supply body, it can be disassembled to provide convenience for the device. The protective cover opens it through deformation to avoid the stability of the ink cartridge.
