A current powder spray marker includes a main body with an inner cavity, a valve core slidably assembled into the inner cavity, and a drive assembly for pushing the valve core to move back and forth along the axial direction of the inner cavity. This drive assembly is based on electronic components such as switches, motors, and reducers, forming an electrically driven system. Its operation depends on a power source, which significantly increases the cost of using and maintaining the drive assembly. Furthermore, the overall assembly occupies a large space, hindering the miniaturization of the powder spray marker. Summary of the Invention

[0003] Therefore, it is necessary to provide a powder-spraying marker to reduce the usage and maintenance costs of the drive components.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A powder-spraying marker includes a spray pen body with an inner cavity, a valve core slidably assembled in the inner cavity, and a driving assembly for pushing the valve core to move back and forth along the axial direction of the inner cavity, wherein the outer wall of the spray pen body is provided with a sliding groove communicating with the inner cavity, and the driving assembly includes:

[0005] A lever, with its inner end extending into the inner cavity and pivotally connected to the cavity wall, and its outer end protruding from the slide groove for the user to press and actuate, wherein the extended end of the lever abuts against a corresponding abutment portion disposed on the outer surface of the valve core; when the lever is actuated, the lever pushes the valve core to slide from the initial position to the trigger position; and,

[0006] A reset elastic element is provided in the inner cavity to apply an elastic counterforce to the valve core so that the valve core slides back to its initial position.

[0007] In one embodiment, the inner end of the lever is provided with a fork, the fork having two fork arms, and the abutment portion being an abutment boss formed by the radial extension of the valve core. The valve core is correspondingly housed within the fork, and the outer surface of the abutment boss abuts against the side walls of the two fork arms.

[0008] In one embodiment, the two fork arms extend to each other on opposite sides, forming a pivot. The cavity wall of the inner cavity has a pivot hole for mounting the pivot. The groove sidewall of the slide is provided with a stop portion that stops the lever in the section of the slide. The stop portion and the pivot hole are obliquely arranged.

[0009] In one embodiment, the arm surface on the fork arm that abuts against the abutting boss is further recessed inward to form a positioning recess. The stepped surface on the abutting boss that abuts against the arm surface is provided with a positioning protrusion at a position corresponding to the positioning recess, which abuts against the positioning recess. The shapes of the positioning recess and the positioning protrusion are adapted to each other. The abutment between the arm surface and the stepped surface positions the lever and the valve core axially, and the abutment between the positioning recess and the positioning protrusion positions the lever and the valve core radially.

[0010] In one embodiment, the portion of the lever exposed in the slide groove constitutes an operating part, and the outer surface of the operating part is provided with an anti-slip texture.

[0011] In one embodiment, the top walls of the groove on both sides of the operating part are further protruding to form side guard plates for correspondingly shielding the outer ends of the operating part.

[0012] In one embodiment, a tongue protrudes from one of the sidewalls of the slide along the length of the slide, and the lever is provided with a corresponding insertion hole for the tongue to be inserted at the position of the section of the slide directly opposite the tongue. The outer end face of the tongue is provided with an identification structure for identifying the insertion direction of the lever.

[0013] In one embodiment, the lever, the slide, and the abutment are all located in the middle section of the airbrush body.

[0014] In one embodiment, a first guide groove and a second guide groove are respectively provided at the front end and the rear end of the inner cavity of the inkjet body for guiding the valve core to slide.

[0015] In one embodiment, the reset elastic element is a compression spring whose opposite ends abut against the stepped portion formed at the end of the valve core and the cavity wall of the inner cavity, respectively.

[0016] The beneficial effects of this utility model are as follows: This utility model provides a powder-jetting marker pen by further configuring the drive assembly as a lever and a reset elastic element. The outer end of the lever, as the operating end, is assembled onto a corresponding groove on the corresponding side of the pen body. The inner end of the lever is pivotally connected to the inner cavity. The extended end of the lever abuts against a corresponding contact portion on the outer surface of the valve core. Thus, the user can press the exposed lever and slide it along the groove. Simultaneously, the lever internally rotatably pushes the valve core to move, causing the valve core to slide from its initial position to the trigger position, thereby triggering the opening of the airflow channel within the valve core. When the user releases the force applied to the lever, the valve core, under the elastic counterforce provided by the reset elastic element, returns to its initial position. This utility model's drive assembly uses a mechanical drive method, which reduces the usage and maintenance costs of the drive assembly and results in a more compact structure.

[0026] In one embodiment, such as Figures 1-5 As shown, a powder-jet marker includes a marker body 1 with an inner cavity 10, a valve core 3 slidably assembled in the inner cavity 10, and a drive assembly for pushing the valve core 3 to move back and forth along the axial direction of the inner cavity 10. The outer wall of the marker body 1 has a groove 11 communicating with the inner cavity 10. The drive assembly includes:

[0027] A lever 51, with its inner end extending into the inner cavity 10 and pivotally connected to the cavity wall of the inner cavity 10, and its outer end protruding from the slide groove 11 for the user to press and actuate, has its inserted end abutting against a corresponding abutment portion 31 provided on the outer surface of the valve core 3. When the lever 51 is actuated, it pushes the valve core 3 to slide from the initial position to the trigger position; and...

[0028] A reset elastic element 53 is provided in the inner cavity 10 to apply an elastic counter-thrust force to the valve core 3 so that the valve core 3 slides back to its initial position.

[0029] Compared with the prior art, the present invention has at least the following advantages: The powder-jetting marker provided by the present invention further configures the driving component as a lever 51 and a reset elastic element 53. The outer end of the lever 51 is assembled as the operating end on the corresponding side of the slide groove 11 of the inkjet body 1, and the inner end of the lever 51 is pivotally connected to the inner cavity 10. The rod body of the extended end of the lever 51 abuts against the abutment part 31 correspondingly provided on the outer surface of the valve core 3. In this way, the user can press the exposed lever 51 and slide it along the groove of the slide groove 11. Simultaneously, the lever 51 rotatably pushes the valve core 3 to move, causing the valve core 3 to slide from the initial position to the trigger position. When the user releases the force applied to the lever 51, the valve core 3 will be reset to the initial position under the elastic counter-force provided by the reset elastic element 53. The driving component of the present invention adopts a mechanical driving method, which can reduce the use cost and maintenance cost of the driving component, and the structure is more compact.

[0030] In one embodiment, such as Figures 1-5 As shown, the inner end of the lever 51 is provided with a fork 511, which has two fork arms 5111. The abutment portion 31 is an abutment boss 310 formed by the radial extension of the valve core 3. The valve core 3 is correspondingly housed in the fork 511, and the outer surface of the abutment boss 310 abuts against the side walls of the two fork arms 5111. In this embodiment, by providing a fork 511 at the inner end of the lever 51, and after the valve core 3 is correspondingly housed in the fork 511, the two ends of the abutment boss 310 on the valve core 3 abut against the two fork arms 5111 of the fork 511, the lever 51 can stably push the valve core 3 to slide.

[0031] In one embodiment, such as Figures 1-5 As shown, pivots 5111 extend from each other on opposite sides of the ends of the two forks 5111. The cavity wall of the inner cavity 10 has a pivot hole 101 for mounting the pivot 5111. The groove sidewall of the slide groove 11 is provided with a stop part 111 that stops the lever 51 in the section of the slide groove 11. The stop part 111 and the pivot hole 101 are obliquely intersecting each other. In this embodiment, a pivot 5111 is integrally formed at the end of the two fork arms 5111. The pivot 5111 is pivotally connected to the pivot hole 101 in the corresponding inner cavity 10. When the outer end of the lever 51 slides along the slide groove 11, the inner end of the lever 51 can rotate smoothly. Simultaneously, the corresponding section of the lever 51 will push the valve core 3, achieving precise rotation control. In addition, a stop part 111 is provided on the side wall of the slide groove 11. The stop part 111 is obliquely arranged with the pivot hole 101. When the valve core 3 is in the initial position, the valve core 3 pushes the lever 51 in the opposite direction under the action of the reset elastic member 53. The obliquely arranged stop part 111 can provide stable and reliable support for the lever 51, ensuring smooth operation.

[0032] In one embodiment, such as Figures 1-5As shown, the arm surface 5112 on the fork arm 5111 that abuts against the abutting boss 310 is also recessed inward to form a positioning recess 5113. The stepped surface 3101 on the abutting boss 310 that abuts against the arm surface 5112 is provided with a positioning protrusion 3103 at a position corresponding to the positioning recess 5113. The shapes of the positioning recess 5113 and the positioning protrusion 3103 are adapted to each other. The abutment between the arm surface 5112 and the stepped surface 3101 positions the lever 51 and the valve core 3 in the axial direction. The abutment between the positioning recess 5113 and the positioning protrusion 3103 positions the lever 51 and the valve core 3 in the radial direction. In this embodiment, the arm surface 5112 of the fork arm 5111 is provided with a positioning recess 5113, and the stepped surface 3101 of the abutment boss 310 is provided with a positioning protrusion 3103. The positioning recess 5113 and the positioning protrusion 3103 have an arc surface structure that matches the shape, which can ensure that the arc surface structure of the two can always maintain smooth contact during the rotation of the lever 51 against the valve core 3. Moreover, the abutment between the arm surface 5112 and the stepped surface 3101 positions the lever 51 and the valve core 3 in the axial direction, and the abutment between the positioning recess 5113 and the positioning protrusion 3103 positions the lever 51 and the valve core 3 in the radial direction. The positioning structure between the fork arm 5111 and the abutment boss 310 is easy to process and has a good positioning effect.

[0033] In one embodiment, such as Figures 1-5 As shown, the portion of the lever 51 exposed in the slide groove 11 constitutes the operating part 513, and the outer surface of the operating part 513 is provided with an anti-slip texture 5130. In this embodiment, the section of the lever 51 exposed in the slide groove 11 is designated as the operating part 513, and an anti-slip texture 5130 is processed on the outer surface of the operating part 513 to enhance the friction during operation.

[0034] In one embodiment, such as Figures 1-5 As shown, the top walls of the groove 11 on both sides of the operating part 513 are also provided with side guard plates 113 for correspondingly shielding the outer ends of the operating part 513. In this embodiment, the side guard plates 113 are provided on the groove 11 to prevent accidental contact with the operating part 513 and to effectively prevent fingers and other parts from getting too close to the outer ends of the operating part 513, thus reducing the risk of fingers being pinched.

[0035] In one embodiment, such as Figures 1-5As shown, a tongue 115 protrudes from one side wall of the slide groove 11 along its length. The lever 51, located within the slide groove 11 and directly opposite the tongue 115, has a corresponding insertion hole 515 for the tongue 115 to be inserted into. The outer end face of the tongue 115 has an identification structure 1150 for marking the insertion direction of the lever 51's insertion hole 515. In this embodiment, by providing mutually interlocking tongues 115 and insertion holes 515 at corresponding locations on the slide groove 11 and the lever 51, when the lever 51 slides along the slide groove 11, the insertion hole 515 accurately leads to the tongue 115, forming a stable positioning fit and improving the accuracy of the lever 51's operation. In specific implementations, the identification structure 1150 can be formed by screen printing or laser engraving.

[0036] In one embodiment, such as Figures 1-5 As shown, the lever 51, the slide 11, and the abutment 31 are all located in the middle section of the airbrush body 1. This embodiment optimizes the center of gravity of the airbrush body 1 by arranging the lever 51, the slide 11, and the abutment 31 all in the middle section of the airbrush body 1. Simultaneously, the user can easily control the lever 51 with their fingers and operate smoothly along the slide 11.

[0037] In one embodiment, such as Figures 1-5 As shown, a first guide groove 105 and a second guide groove 106 are respectively provided at the front and rear ends of the inner cavity 10 of the airbrush body 1 to guide the valve core 3 to slide. In this embodiment, by providing the first guide groove 105 and the second guide groove 106 at the front and rear ends of the airbrush body 1, the accuracy of the valve core 3 sliding can be improved.

[0038] In one embodiment, such as Figures 1-5 As shown, the reset elastic element 53 is a compression spring whose two ends respectively abut against the stepped portion 35 formed at the end of the valve core 3 and the cavity wall of the inner cavity 10. In this embodiment, by using a compression spring as the reset elastic element 53, with its two ends assembled to the stepped portion 35 and the cavity wall of the inner cavity 10, an elastic counterforce can be effectively provided to the valve core 3 to reset it. In specific implementations, the reset elastic element 53 can also be other components such as torsion springs or spring sheets to achieve the same effect.

[0039] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
