In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] Example 1

[0025] Please see Figures 1-5As shown, this embodiment discloses an inkjet gun compatible with various pen-shaped markers, including a housing assembly 1, an inkjet gun assembly 2, an air pump assembly 3, a rechargeable lithium battery 4, and a button 5. The inkjet gun assembly 2 includes a pen-shaped guide tube 201 and a nozzle 202. The inner diameter of the pen-shaped guide tube 201 is approximately 20mm. For ease of assembly, the housing assembly 1 includes a front housing 103 and a rear housing 104, which are fastened together to form a receiving space 10. 5. The accommodating space 105 is divided into an upper cavity 101 and a lower cavity 102. An insertion port 1021 is provided on one side of the upper cavity 101, and a nozzle 202 partially protruding from the outer side of the outer shell assembly 1 is inserted into the other end of the upper cavity 101. An inkjet nozzle 2021 is provided at the end of the nozzle 202 away from the upper cavity 101. To achieve limiting, a limiting ring 8 and a limiting ring 9 are provided inside the upper cavity 101. The outer side of the pen-shaped guide tube 201 is provided with... The nozzle 202 has a limiting groove 10 that mates with the limiting ring 8, and a limiting groove 11 that mates with the limiting ring 9 on the outer side. The air pump assembly 3 is fixed inside the lower cavity 102. The air pump assembly 3 is connected to the nozzle 202 via an air pipe 19, thereby driving the nozzle 202 to work. The button 5 is connected to the air pump assembly 3 and is used to control the operation of the nozzle 202. The rechargeable lithium battery 4 is electrically connected to the air pump assembly 3. The pen-shaped guide tube 201 is disposed in... Inside the upper cavity 101, one end of the pen-shaped guide tube 201 is inserted into the nozzle 202. A small pen fixing sleeve 6 is detachably inserted into the insertion port 1021. The inner through hole 601 of the small pen fixing sleeve 6 has a diameter of about 1 cm. One end of the small pen fixing sleeve 6 is inserted into the other end of the pen-shaped guide tube 201. The small pen fixing sleeve 6 is provided with an inner through hole 601 that connects the two ends. A soft silicone layer 602 is provided on the inner side of the inner through hole 601.

[0026] Preferably, for convenient charging, the bottom of the housing assembly 1 is provided with a USB charging port 7, which facilitates charging later.

[0027] Preferably, to effectively secure the marker, a pen-shaped adjusting sleeve 12 is provided inside the end of the pen-shaped guide tube 201 near the nozzle 202. The pen-shaped adjusting sleeve 12 is made of soft silicone. Inside the nozzle 202, one or more positioning brackets 13 are arranged in a ring around the inkjet nozzle 2021. All positioning brackets 13 constitute a clamp for holding the pen. One end of the pen-shaped adjusting sleeve 12 abuts against one end face of the positioning bracket 13. This structure, by adding the pen-shaped adjusting sleeve 12, utilizes a soft material... Therefore, when markers of different sizes are inserted into the pen-shaped adjustment sleeve 12, markers of different sizes can be clamped. However, considering that the adjustment range of the pen-shaped adjustment sleeve 12 is not large, it can only fix markers with small size differences. When the diameter is smaller than the inner diameter of the pen-shaped adjustment sleeve 12, the clamping effect becomes relatively poor, which is the case for small markers. At this time, it can be fixed by the small pen fixing sleeve 6 above. At the same time, several positioning brackets 13 cooperate to form an adjustable clamping opening to achieve the clamping operation of the marker head.

[0028] As a preferred option, to improve the sealing effect and prevent air leakage from affecting the inkjet effect, a sealing ring 14 is provided between the pen-shaped guide tube 201 and the nozzle 202. By providing a sealing ring 14 between the pen-shaped guide tube 201 and the nozzle 202, the sealing effect is improved and air leakage is prevented from affecting the subsequent inkjet effect.

[0029] This structure features a detachable pen retainer 6 inserted into the insertion port 1021. The pen retainer 6 is used to limit and fix relatively small-diameter markers. That is, when the pen retainer 6 is not used, this structure can fix markers with a diameter slightly smaller than the pen-shaped guide tube 201 (i.e., standard-sized markers). After inserting such a marker into the pen-shaped guide tube 201 through the insertion port 1021, the head is locked into the nozzle 202, and then the air pump assembly 3 is driven to work, achieving ink ejection. When the marker is small (i.e., the diameter of the marker differs significantly from that of a standard-sized marker), this structure can achieve ink ejection. When the diameter of such markers is generally around 1 cm, a small pen holder 6 can be used. The small pen holder 6 is first inserted into the insertion port 1021, and then the head of the marker is inserted into the small pen holder 6 and locked in the nozzle 202. This achieves the positioning and fixing of the small marker, and avoids the problem of it shaking due to the large gap between it and the pen-shaped guide tube 201. In addition, since the inner side of the inner through hole 601 is provided with a soft silicone layer 602, the small pen holder 6 has a certain degree of elasticity, which can also clamp some small markers with slight diameter errors.

[0030] Example 2

[0031] Please see Figure 6As shown, this embodiment discloses an inkjet gun that can be used with various pen-shaped markers. Preferably, to further achieve the fixing function of different pens, the pen-shaped guide tube 201 is further provided with a C-shaped pen barrel positioning assembly arranged in a vertically mirrored configuration. The C-shaped pen barrel positioning assembly includes a C-shaped positioning clip 15 with its opening facing the central axis of the pen-shaped guide tube 201. One or more adjusting rods 16 are arranged in a ring around the outside of the C-shaped positioning clip 15. One end of each adjusting rod 16 is hinged to the C-shaped positioning clip 15, and the other end extends out of the pen-shaped guide tube 201. In addition, a spring 17 is sleeved on the adjusting rod 16. One end of the spring 17 abuts against the inner wall of the pen-shaped guide tube 201, and the other end abuts against the hinge point between the C-shaped positioning clip 15 and the adjusting rod 16. A soft anti-slip layer 18 is provided inside the opening of the C-shaped positioning clip 15. Through the above structure, markers of different diameters can be fixed. When the marker is inserted into the pen-shaped guide tube 201, the C-shaped pen barrel positioning components arranged vertically and horizontally can clamp markers of different sizes, realizing the versatility of this device.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
