Description

Technical Field

[0001] The present invention relates to the technical field of dot plotting pens, and in particular to an electromagnetic vibration dot plotting pen structure. The present invention also relates to a dot plotter provided with the electromagnetic vibration dot plotting pen structure. Background Art

[0002] The dot painting method, also known as pointillism, is a painting technique of Neo-Impressionism. This technique uses many small, dense colored dots or black and white dots to create a dazzling effect, and the arrangement, color, size and other changes of the dots form lines and surfaces to shape the entire picture.

[0003] Dot drawing is not only done with a brush on paper, but also with tattoo pens, embroidery pens, etc. There are many types of pens for drawing on paper, such as pencils, fountain pens, and colored pencils, which can create different painting styles. Each type of pen can be divided into multiple refills of different colors according to the color.

[0004] Therefore, the workload of painting with the pointillism method is large, and the painter needs to have extremely high hand control ability and patience. In addition, since the size, density and arrangement of each dot in the pointillism method need to be carefully designed to express different light and shade and color changes, this requires the painter not only to have certain requirements on the strength of the brushstrokes, but also to make precise plans for the layout of the density of the dot painting, which increases the difficulty of painting and often cannot guarantee an accurate painting cycle. As a result, the learning threshold of pointillism painting is relatively high, which is not conducive to the widespread promotion of this painting method.

[0005] In the prior art, there is a method of using a computer to control the pen tip to draw, so as to increase the speed of drawing and the uniformity of the pen stroke, but this method cannot achieve different painting effects due to different pen stroke strengths, and this method is cumbersome when replacing pen refills of different colors, and the drawing efficiency is low. Summary of the invention

[0006] In view of this, the present invention aims to propose an electromagnetic vibration dot painting pen structure to reduce the painting difficulty of the painter, and to enable quick replacement of the pen core, thereby effectively shortening the dot painting creation time.

[0007] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0008] An electromagnetic vibration dot painting pen structure comprises an electromagnetic sleeve, a vibration tube slidably connected in the electromagnetic sleeve, and a clamping member detachably connected to the bottom end of the vibration tube;

[0009] A coil portion is provided on the outside of the electromagnetic sleeve, and the coil portion is electrically connected to an external power supply;

[0010] A first magnet is sleeved on the outer side of the vibration tube, a second magnet is arranged at the lower end of the vibration tube, and a third magnet attracted to the second magnet is arranged on the clamping member;

[0011] When the coil portion is energized, the vibration tube vibrates along the axial direction of the electromagnetic sleeve due to the electromagnetic force formed by the first magnet and the coil portion;

[0012] The clamping piece is used for installing the pen core, and a receiving cavity for receiving the pen core is formed in the vibration tube.

[0013] Furthermore, a protective sleeve is provided on the outside of the electromagnetic sleeve, and the protective sleeve is fixedly connected to the body;

[0014] The upper end of the casing is provided with a screw-connected protective cap;

[0015] The clamping piece is partially exposed below the casing.

[0016] Furthermore, a second limiting member is provided at the lower end of the body, and the second limiting member is sleeved on the vibration tube;

[0017] The protective sleeve has a cylindrical inner cavity, and the electromagnetic sleeve is arranged in the inner cavity;

[0018] A radially arranged retaining ring is further provided in the casing, and the inner diameter of the retaining ring is smaller than the outer diameter of the second limiting member;

[0019] The retaining ring is disposed below the second limiting member to prevent the vibration tube from escaping from the casing.

[0020] Further, the vibration tube includes a cylindrical section and a conical section disposed below the cylindrical section;

[0021] The first magnet is sleeved on the cylindrical section, and the second magnet is arranged at the end of the conical section;

[0022] The taper of the conical section is gradually increased from the cylindrical section toward the second magnet.

[0023] Furthermore, the clamping member further comprises a connecting section and a clamping section, the third magnet is arranged on the connecting section; the clamping section is provided with a plurality of clamping claws evenly distributed around the circumference;

[0024] The clamping claw is used for clamping the pen core.

[0025] Furthermore, the clamping claw is made of elastic material.

[0026] Furthermore, the third magnet and the connecting section are integrally formed, and / or the second magnet and the conical section are integrally formed.

[0027] Furthermore, the vibration tube is made of carbon fiber.

[0028] Compared with the prior art, the present invention has the following advantages:

[0029] The electromagnetic vibration dot painting pen structure of the present invention is provided with an electromagnetic sleeve having a coil part and a vibration tube slidably connected in the electromagnetic sleeve. When the coil part is energized, a magnetic field is formed to form electromagnetic induction with the first magnet, driving the first magnet and the vibration tube to vibrate along the axial direction of the electromagnetic sleeve. And through the attraction performance of the second magnet and the third magnet, it is convenient to quickly disassemble and install the clamping part and the vibration tube, so as to replace different pen cores for painting. The pen core vibrates up and down with the vibration tube. The painter does not need to exert effort to hold the dot painting pen, but only needs to control the moving direction of the dot painting pen and the force of the pen to complete the painting, which reduces the painting difficulty of the dot painting method and shortens the painting time of the dot painting method.

[0030] In addition, an elastic member is arranged on the outside of the vibration tube, so that after the pen core is lowered into place and the coil is powered off, the elastic member releases energy to make the vibration tube rise and reset. A first limiter is arranged on the upper end of the elastic member to prevent the elastic member from falling out of the vibration tube. A protective sleeve is also arranged on the outside of the electromagnetic sleeve to protect the coil from being exposed, thereby increasing the stability of the dot drawing pen structure in use, and a nut threadedly connected to the protective sleeve is arranged to adjust the compression of the spring, thereby adjusting the vibration amplitude of the pen core.

[0031] In addition, by setting the vibration tube to carbon fiber material, the axial strength and modulus of the vibration tube are improved, so as to increase the structural strength of the vibration tube, enable it to withstand high pressure and weight, adapt to the replacement of multiple specifications of pen cores, and increase the service life of the dot pen structure.

[0032] Another object of the present invention is to provide a dot plotter, which includes the electromagnetic vibration dot plotter structure as described above and an electromagnetic pulse transmitter electrically connected to the coil portion.

[0033] The dot plotter of the present invention transmits current signals to the coil part by arranging an electromagnetic pulse transmitter so that the coil part forms magnetic fields in different directions to drive the vibration tube to carry the pen core to vibrate, thereby achieving the effect of dot plotting, improving the drawing efficiency of the dot plotter and reducing the work intensity of the painter.

[0053] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0054] This embodiment relates to an electromagnetic vibration dot painting pen structure, such as Figure 1 to Figure 2 As shown, the electromagnetic vibration dot drawing pen structure includes an electromagnetic sleeve 1, a vibration tube 2 slidably connected in the electromagnetic sleeve 1, and a clamp 3 detachably connected to the bottom end of the vibration tube 2. A coil portion 4 is provided on the outside of the electromagnetic sleeve 1, and the coil portion 4 is electrically connected to an external power supply. A first magnet 5 is sleeved on the outside of the vibration tube 2, a second magnet 6 is provided at the lower end of the vibration tube 2, and a third magnet 7 attracted to the second magnet 6 is provided on the clamp 3. When the coil portion 4 is energized, the vibration tube 2 vibrates along the axial direction of the electromagnetic sleeve 1 due to the electromagnetic force formed by the first magnet 5 and the coil portion 4. The clamp 3 is used to install the pen core 8, and a accommodating cavity 301 for accommodating the pen core 8 is formed in the vibration tube 2.

[0055] As described above, the electromagnetic vibration dot painting pen structure of this embodiment is provided with an electromagnetic sleeve 1 having a coil part 4, and a vibration tube 2 slidably connected in the electromagnetic sleeve 1. When the coil part 4 is energized, a magnetic field is formed to form electromagnetic induction with the first magnet 5, driving the first magnet 5 and the vibration tube 2 to vibrate along the axial direction of the electromagnetic sleeve 1. And through the attraction performance of the second magnet 6 and the third magnet 7, it is convenient to quickly disassemble and install the clamping part 3 and the vibration tube 2, so as to replace different pen cores 8 for painting. The pen core 8 vibrates up and down with the vibration tube 2. The painter does not need to exert effort to hold the dot painting pen, and only needs to control the moving direction of the dot painting pen and the force of the pen to complete the painting, which reduces the painting difficulty of the dot painting method and shortens the painting time of the dot painting method.

[0056] Based on the above overall introduction, an exemplary structure of the electromagnetic vibration dot painting pen structure of this embodiment is as follows: Figures 4 to 5 As shown, the vibration tube 2 and the electromagnetic sleeve 1 are both rotary column structures. Preferably, the electromagnetic sleeve 1 includes a body 101, and the coil part 4 is wrapped outside the body 101; the coil part 4 is a coil sleeve formed by copper wire. The body 101 is made of materials such as plastic, ceramic, etc.

[0057] like Figures 4 to 6 As shown, in order to facilitate the winding of the coil, a groove for winding the coil is provided on the body 101, and the coil is wound layer by layer on the outside of the body 101. An elastic member 9 is sleeved on the outside of the vibration tube 2, and a first limiter 10 is provided on the upper end of the elastic member 9, and the lower end of the elastic member 9 abuts against the body 101. The first limiter 10 is sleeved on the vibration tube 2 to limit the displacement of the elastic member 9. The first limiter 10 of this embodiment adopts an O-ring, of course, it is not limited to this structure, and parts such as a shaft retaining ring, a nut, etc. that play a limiting role can also be used.

[0058] The first magnet 5 is a circular ring structure and is sleeved and fixed on the vibration tube 2. The first magnet 5 is arranged at a position corresponding to the coil part 4. The elastic member 9 in this embodiment adopts a telescopic spring. When the vibration tube 2 is driven to move downward to the extreme position, the elastic member 9 is compressed to store energy. One end of the elastic member 9 abuts against the upper end of the main body 101, and the other end is limited by the first limit member 10. Because the coil part 4 needs to be powered off when reversing, in order to ensure the smooth reversing process, the elastic energy release and rebound of the elastic member 9 can be used to reset the vibration tube 2. As a preferred implementation mode, Figures 1 to 3 As shown, a protective sleeve 11 is provided on the outside of the electromagnetic sleeve 1, and the protective sleeve 11 is fixedly connected to the body 101. A screwed protective cap 12 is provided on the upper end of the protective sleeve 11, and the clamping member 3 is partially exposed below the protective sleeve 11. The protective sleeve 11 is a straight tube structure, and the protective sleeve 11 is provided to protect the coil part 4 from being exposed outside, thereby increasing the service life of the dot pen structure and reducing the failure rate.

[0059] In addition, if Figure 2 and Figure 3 As shown, the casing 11 has a cylindrical inner cavity, and the electromagnetic sleeve 1 is arranged in the inner cavity. A radially arranged retaining ring 1101 is also arranged in the casing 11, and the inner diameter of the retaining ring 1101 is smaller than the outer diameter of the second stopper 13. The retaining ring 1101 is placed below the second stopper 13 to prevent the vibration tube 2 from slipping out of the casing 11. Figure 3 As shown, the protective cap 12 of this embodiment adopts a box body structure with an opening at one end. The opening of the protective cap 12 faces downward and is connected to the inner cavity of the protective tube 11. When the upper end of the vibration tube 2 rises, it abuts against the top wall of the protective cap 12. By adjusting the distance between the top wall of the protective cap 12 and the protective tube 11, the vibration stroke of the vibration tube 2 can be adjusted.

[0060] It should be noted that, for ease of use, in this embodiment, the coil of the negative pole of the coil is connected to the external sheath 11, the sheath 11 is made of, for example, aluminum alloy, and a negative lead is connected to the outside of the sheath 11 for connection to the negative pole of the external power source. The positive pole line of the coil extends upward along the inner cavity of the sheath 11 and passes through the protective cap 12, and the positive pole line is used to connect to the positive pole of the power source.

[0061] like Figure 7 As shown, the vibration tube 2 includes a cylindrical section 201 and a conical section 202 arranged below the cylindrical section 201. The first magnet 5 is sleeved on the cylindrical section 201, and the second magnet 6 is arranged at the end of the conical section 202. The taper of the conical section 202 is gradually increased from the cylindrical section 201 to the direction of the second magnet 6. The outer diameter of the cylindrical section 201 is adapted to the inner hole of the body 101. By setting the conical section 202, the setting area of ​​the second magnet 6 can be increased, and the adsorption of the second magnet 6 and the third magnet 7 can be improved to adapt to the adsorption of brushes of various specifications.

[0062] Preferably, the vibration tube 2 of this embodiment is made of carbon fiber. By setting the vibration tube 2 to be made of carbon fiber, the axial strength and modulus of the vibration tube 2 are improved, so as to increase the structural strength of the vibration tube 2, so that it can withstand high pressure and weight, adapt to the replacement of multiple specifications of the refill 8, and increase the service life of the dotting pen structure.

[0063] like Figure 3 and Figure 8 As shown, the clamping member 3 also includes a connecting section 301 and a clamping section, and the third magnet 7 is arranged on the connecting section 301. The clamping section is provided with a plurality of clamping claws 302 evenly distributed around the circumference, and the clamping claws 302 are used to clamp the pen core 8. The third magnet 7 is annular, and the connecting section 301 and the clamping section are arranged at one end of the conical section 202 of the third magnet 7. Figure 8 As shown, the connecting section 301 is tapered from the upper end to the lower end, so as to gradually tighten the pen core 8.

[0064] In order to adapt to various refills 8, the clamping jaw 302 is made of elastic material. More specifically, the connecting section 301 and the clamping section of this embodiment are made of rubber material, and the clamping section can also add elastic steel sheets such as spring steel to improve the rigidity of the clamping section. In actual use, for example, an embroidery pen or a tattoo pen or a pen with a thinner diameter can be connected to the refill 8 and the adapter by making an intermediate adapter, and then connected to the clamping section.

[0065] Preferably, the third magnet 7 is integrally formed with the connecting section 301 by injection molding, and the second magnet 6 is integrally formed with the conical section 202 by injection molding. In other embodiments, the third magnet 7 and the connecting section 301 or the second magnet 6 and the conical section 202 can be integrally formed by bolt fixing or hot melting.

[0066] This embodiment also relates to a dot plotter, which includes the electromagnetic vibration dot plotter structure as described above, and an electromagnetic pulse transmitter electrically connected to the coil part 4. The structure of the electromagnetic pulse transmitter is the same as that of the prior art, and is also provided with a main board, in which a chip for transmitting pulses is provided, and the chip transmits a pulse current, so that the coil part 4 generates a frequency magnetic field. The electromagnetic pulse transmitter is also integrated with a battery, a charging port, etc.
