Description

Technical Field

[0001] The utility model belongs to the field of printers, in particular to a portable inkjet printer. Background Art

[0002] An inkjet printer is an output device that transmits computer data via a specific print interface to the printer's print logic control unit, which then sprays toner or ink onto the print medium through a printhead, completing the printing process. During operation, the inkjet printer converts digital information from the computer into instructions that the printhead can understand. These instructions are then transmitted to the inkjet printhead, which consists of multiple tiny nozzles, each capable of independently ejecting ink. When the nozzle receives an instruction, it rapidly heats the ink, causing it to form tiny bubbles that rapidly expand, squeezing the ink from the nozzle and ejecting it onto the paper. As the printhead moves, the ink is precisely sprayed onto different locations on the paper according to the instructions, forming the desired image or text.

[0022] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] Example 1:

[0024] As attached Figure 1 To the attached Figure 4 As shown:

[0025] The utility model provides a portable inkjet printer, comprising a body 1 and a protective cover 2. A paper discharge end 3 is provided on the front of the body 1, and a paper feed end 4 is provided on the back. An ink reservoir 5 is provided on one side of the body 1 located at the paper discharge end 3, and a hatch 6 is hingedly connected to the ink reservoir 5. A control panel 7 is provided on one side of the top of the body 1. The top and bottom of one corner of the body 1 are both connected to vertical shafts 8. One end of the two vertical shafts 8 is rotatably connected to the top and bottom of the inner side of the protective cover 2 through bearings. A locking mechanism for locking the top vertical shaft 8 is provided on the outer side of the protective cover 2.

[0026] refer to Figure 2 The protective cover 2 is set as a structure with two side openings, and a clearance opening 9 is opened on the rear side for making way when rotating.

[0027] Wherein, through the structure of openings on both sides, the protective cover 2 can be opened when not needed so as to allow the printer to be used normally.

[0029] The universal wheels 10 can be used to slide the body 1 out of the protective cover 2 when the printer needs to be used, so as to facilitate switching the relative states of the two.

[0030] refer to Figure 1 A handle 12 is provided on the top of the protective cover 2, which is used to apply a pulling force to the protective cover 2.

[0031] Example 2:

[0032] As attached Figure 1 To the attached Figure 4 As shown:

[0033] The present utility model provides a portable inkjet printer. Based on the above embodiment, this embodiment further describes in detail the specific components of the locking mechanism and the specific locking method of the vertical shaft 8.

[0034] refer to Figure 3 and Figure 4 The locking mechanism includes a lifting ear 13, a horizontal column 14, a compression spring 15, a disc 16, a latch 17 and a handle 12. The lifting ear 13 is installed on the inner top wall of the opening side of the body 1. A horizontal column 14 slides through the middle of the lifting ear 13. One end of the horizontal column 14 is connected to the handle 12, and the other end of the horizontal column 14 is connected to the disc 16. A latch 17 is provided on the side of the disc 16. The compression spring 15 is sleeved on the horizontal column 14, and its two ends respectively abut against the opposite sides of the lifting ear 13 and the disc 16.

[0035] refer to Figure 4 Two groups of insertion holes 18 are provided on the outer side wall corresponding to the vertical shaft 8 , and one end of the latch 17 extends to the inner side of the corresponding insertion hole 18 and is plugged into the vertical shaft 8 .

[0036] Among them, when it is necessary to switch the relative state of the protective cover 2 and the body 1, the handle 12 is pushed outward, so that the handle 12 drives the horizontal column 14 to move. When the horizontal column 14 moves, the disc 16 drives the pin 17 to disengage from the originally aligned socket 18, that is, the relative limit of the vertical axis 8 and the protective cover 2 is released. At this time, the body 1 can be pushed into the protective cover 2 or moved out of the protective cover 2.

[0037] refer to Figure 4 A through hole 19 is provided in the middle of the lifting ear 13 for the horizontal column 14 to move, and the cross sections of the through hole 19 and the horizontal column 14 are both arranged in a cross-shaped structure.

[0038] The cross-shaped structure limits the movement trajectory of the cross column 14 to ensure its stability when moving relative to the lifting lug 13 .

[0039] Working principle: When the printer needs to be carried, push the handle 12 outward so that the handle 12 drives the horizontal column 14 to move, and the movement of the horizontal column 14 drives the disc 16 to move. During the movement of the disc 16, on the one hand, it will squeeze the compression spring 15, and on the other hand, it will drive the latch 17 to disengage from the originally aligned socket 18, that is, the relative limit of the vertical axis 8 and the protective cover 2 is released. At this time, the body 1 can be pushed into the protective cover 2 or moved out of the protective cover 2. After moving out, the latch 17 will be realigned with another socket 18. At this time, release the handle 12, and the compression spring 15 releases the elastic restoring force, which will drive the disc 16 to pull the horizontal column 14 to reset and move. During the movement, the latch 17 is inserted into the socket 18 again, completing the locking of the relative state of the protective cover 2 and the body 1.
