A paper outlet hole 111 is provided between the first housing 11 and the second housing 12 for the printed paper to pass through. The shielding member 2 can be switched between an open state and a closed state. In the open state, the paper outlet hole 111 can normally output paper and print normally; in the closed state, the shielding member 2 blocks the paper outlet hole 111 to prevent dirt such as water, oil, and dust from entering the interior of the printer 100 through the paper outlet hole 111 and causing a malfunction, so as to protect the printer 100, reduce maintenance costs, and extend the service life of the printer 100.

[0022] Optionally, the first shell 11 and the second shell 12 may be integrated or separated.

[0023] In some embodiments, the shielding member 2 includes a first end 21 and a second end 22 that are disposed opposite to each other, the second end 22 is rotatably connected to the first shell 11 , and the first end 21 fits with the second shell 12 to close the paper outlet hole 111 .

[0024] Optionally, the second end 22 is axially connected to the first housing 11 to ensure smooth rotation.

[0025] In some embodiments, the shielding member 2 is retractable. The shielding member 2 is extended to the closed state to cover the paper outlet hole 111 , and the shielding member 2 is retracted to the open state to allow normal paper outlet.

[0026] In some embodiments, the shielding member 2 may be extended and retracted by a power source.

[0027] In some embodiments, the printer 100 includes a housing 1 and a cover 3 , the cover 3 can be opened relative to the housing 1 , the housing 1 includes the first shell 11 , and the cover 3 includes the second shell 12 .

[0028] In some embodiments, the hardness of the shielding member 2 is less than that of the housing 1 , and may be made of silicone or rubber, etc., which not only increases the fitting effect but also prevents the shielding member 2 from scratching the cover plate 3 .

[0029] In some embodiments, only the first end 21 of the shielding member 2 may have a hardness smaller than that of the housing 1 , so as to facilitate the installation of the shielding member 2 and ensure the stability of the shielding member 2 .

[0030] The printer 100 includes a core assembly 4 located below the cover plate 3 , and the shielding member 2 shields the paper outlet hole 111 to prevent dirt such as water, oil, and dust from entering the interior of the printer 100 through the paper outlet hole 111 , thereby protecting the core assembly 4 .

[0031] The printer 100 includes a circuit board 5 located in a space surrounded by a housing 1 , and the core assembly 4 is electrically connected to the circuit board 5 .

[0032] In some embodiments, a protruding portion 121 is provided on the second shell 12, and the protruding portion 121 includes a side wall 1211 and a top wall 1212 connected to the side wall 1211, the top wall 1212 is higher than the top surface of the first shell 11, the first end 21 is in contact with the side wall 1211, and the top wall 1212 is located above the shielding member 2 to further provide shielding to prevent water, oil, dust and other contaminants from entering the interior of the printer 100 through the paper outlet hole 111.

[0033] In some embodiments, the thickness of the first end 21 is smaller than the thickness of the second end 22 to ensure the fit between the shielding member 2 and the second shell 12 ; the space occupied by the shielding member 2 can also be saved.

[0034] In some embodiments, the shielding member 2 gradually becomes thinner from the second end 22 to the first end 21 .

[0035] In some embodiments, the shielding member 2 is attracted by magnetic force to rotate to the open state.

[0036] In some embodiments, when the printer 100 is printing normally, the shielding member 2 is attracted by magnetic force to rotate to the open state; after printing is completed, the magnetic force disappears, and the shielding member 2 rotates to the closed state. Optionally, the printer 100 includes an electromagnet, and when the printer 100 is working normally, the electromagnet is powered on to generate an adsorption force, and after printing is completed, the electromagnet is powered off and the adsorption force disappears.

[0041] In some embodiments, the printer 100 includes a coupled detection device 71 and a control device 72, and the control device 72 controls the motor 6 according to the detection result of the detection device 71 to realize the automatic closing and opening of the shielding member 2, which is more user-friendly. Optionally, the shielding member 2 can also be opened and closed manually.

[0042] In some embodiments, the printer 100 includes a torsion spring 8, and the torsion spring 8 is located between the shielding member 2 and the first housing 11. The elastic force of the torsion spring 8 keeps the shielding member 2 in the closed state, ensuring that the shielding member 2 can be closed normally. Optionally, when the shielding member 2 is closed, the elastic force of the torsion spring 8 does not need to be too large, and the printing paper can still be pulled out from the paper outlet 111.

[0043] The housing 1 is provided with a paper bin 112. The printing paper is in a roll and is stored in the paper bin 112. The printer 100 includes a print head 91 and a rubber roller 92, and the print head 91 and the rubber roller 92 clamp the printing paper. When printing, the print head 91 is heated to make the printing paper visible; at the same time, the rubber roller 92 rotates to drive the printing paper to be discharged from the paper outlet 111.

[0044] Optionally, the detection device 71 can be used to detect whether the printer 100 is printing, for example, it can detect whether the rubber roller 92 is rotating, etc. The detection device 71 can be a camera, a sensor, or a switch, etc.
