Description

Technical Field

[0001] This utility model relates to a magnetic writing pen suitable for magnetic writing boards. Background Technology

[0002] A magnetic pen, through its magnetic tip at the writing end, attracts magnetic particles on the writing surface of a magnetic writing board when writing, causing these particles to come close to the writing surface, thus displaying the written text or pattern.

[0003] Currently, magnetic writing pens use a single magnetic rod structure at the tip. During writing, the tip's position relative to the magnetic writing board remains constant, resulting in a relatively fixed distribution of magnetic lines of force relative to the writing board. However, because the magnetic particles inside the writing board are arranged in different directions, some particles experience insufficient magnetic attraction, preventing them from moving or reaching their intended positions. This results in an insufficient number of magnetic particles near the writing surface, making it difficult to attract all the particles to the vicinity of the pen tip. Consequently, the written content appears blurry and pale on the magnetic writing board. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a magnetic writing pen that solves the problem of difficulty in attracting sufficient magnetic particles, resulting in a blurry and light-colored display on the magnetic writing board.

[0005] A magnetic writing pen is provided, suitable for magnetic writing boards, the magnetic writing pen comprising:

[0006] Hold the pen;

[0007] A pen tip assembly is connected to one end of the pen barrel and includes a flexible connector and a pen tip structure. The pen tip structure includes multiple magnetic rods, each of which has a connecting end and a writing end. The connecting end of each magnetic rod is connected to the flexible connector.

[0008] When the writing end of the magnetic rod is subjected to an external force, the connection point of the connection end of the magnetic rod to which the flexible connector is connected will deform accordingly.

[0009] Optionally, at least one pair of adjacent magnetic rods are spaced apart from each other.

[0010] Optionally, the magnetic bars are arranged in a ring array.

[0011] Optionally, the pen tip assembly further includes a magnetic ring, which is fitted onto the pen tip structure and is used to prevent the circumferential leakage of the magnetic rod.

[0012] Optionally, a plurality of positioning grooves are formed on the inner ring surface of the magnetic ring;

[0013] The magnetic rods are arranged in a ring array;

[0014] Each of the aforementioned positioning grooves positions one of the aforementioned magnetic rods;

[0015] At least a portion of the flexible connector is disposed within the magnetic ring and is used to press the connecting ends of each of the magnetic rods against the magnetic ring.

[0016] Optionally, the flexible connector is a flexible connector formed by dripping adhesive.

[0017] Optionally, the magnetic writing pen further includes a pen tip structure;

[0018] The pen tip structure includes a connecting part and a conical part. The connecting part is detachably connected to the pen grip. The cone tip of the cone part faces away from the connecting part. The cone tip of the cone part has a mounting groove for mounting the pen tip assembly.

[0019] Optionally, the pen grip is provided with a plug-in hole;

[0020] The connecting part is inserted into the insertion hole;

[0021] The outer peripheral surface of the connecting part is provided with one of an annular groove and an annular retaining ring, and the inner wall surface of the insertion hole is provided with the other of an annular groove and an annular retaining ring, wherein the annular groove and the annular retaining ring are engaged with each other.

[0022] Optionally, the magnetic pen further includes a magnetizing magnet;

[0023] The magnetizing magnet is located inside the pen holder and generates a magnetizing magnetic field, which is used to enhance the magnetism of the magnetic rod.

[0024] Optionally, the magnetic pen may further include an electromagnetic component;

[0025] The electromagnetic component is used to generate an electromagnetic magnetic field, which is used to enhance the magnetism of the magnetic rod.

[0026] Based on the structural design of this utility model, in actual use, the writing end of the magnetic rod will abut against the writing surface of the magnetic writing board and be subjected to external force. At this time, the flexible connector can deform accordingly according to the magnitude and direction of the external force, so that the position and angle of the magnetic rod change, thereby changing the distribution of magnetic lines of force. Since the pen tip assembly includes multiple magnetic rods, the position and angle of each magnetic rod change differently. This makes it easier for the magnetic particles with different orientations inside the magnetic writing board to match the magnetic rods that can cause them to move. This ensures that there are enough magnetic particles close to the writing surface of the magnetic writing board, thereby avoiding the problem of blurry and light-colored display of the written content on the magnetic writing board. It significantly improves the writing effect of the magnetic pen on the magnetic writing board, making the display clearer and more vivid. Attached Figure Description

[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0046] This utility model provides a magnetic writing pen suitable for magnetic writing boards.

[0047] Please see Figures 1 to 3 The magnetic pen includes a grip 100 and a pen tip assembly 200.

[0048] The pen grip 100 is for the user to hold, and its specific structure, materials, etc. can be selected and set as needed, and are not limited here.

[0049] The pen tip assembly 200 is connected to one end of the pen barrel and includes a flexible connector 210 and a pen tip structure 220. The pen tip structure 220 includes a plurality of magnetic rods 221, each of which has a connecting end and a writing end. The connecting end of each magnetic rod 221 is connected to the flexible connector 210. It should be noted that the pen tip assembly 200 is a structural component used for interaction with the magnetic writing tablet to attract the magnetic particles of the magnetic writing tablet.

[0050] When the writing end of the magnetic rod 221 is subjected to an external force, the connection point of the flexible connector 210 to the connecting end of the magnetic rod 221 will deform accordingly.

[0051] Based on the structural design of this utility model, in specific use, the writing end of the magnetic rod 221 will abut against the writing surface of the magnetic writing board and be subjected to external force. At this time, the flexible connector 210 can deform accordingly according to the magnitude and direction of the external force, so that the position and angle of the magnetic rod 221 change, thereby changing the distribution of magnetic lines of force. Since the pen tip assembly 200 includes multiple magnetic rods 221, the position and angle of each magnetic rod 221 are different. This makes it easier for the magnetic particles with different orientations inside the magnetic writing board to match the magnetic rods 221 that can make them move. This ensures that there are enough magnetic particles close to the writing surface of the magnetic writing board, thereby avoiding the problem of blurry display and light color of the written content on the magnetic writing board. It significantly improves the writing effect of the magnetic pen on the magnetic writing board, making the display clearer and more vivid.

[0052] It should be noted that whether the writing end of the magnetic rod 221 is the N-pole or the S-pole is set according to the requirements and is not limited here.

[0053] In this embodiment, at least one pair of adjacent magnetic rods 221 are spaced apart. This allows the magnetic rods 221 to retain a certain amount of lateral deformation space.

[0054] It should be noted that the magnetic rods 221 can also be fitted together relatively tightly, and during use, the magnetic rods 221 can still be displaced at least in the vertical direction.

[0055] Preferably, in this embodiment, each of the magnetic rods 221 is arranged in a ring array on the flexible connector 210.

[0056] See Figures 1 to 4 In this embodiment, the pen tip assembly 200 further includes a magnetic ring 230, which is sleeved on the pen tip structure 220 and used to block the circumferential leakage of the magnetic rod 221. This effectively prevents the erasure or fading of surrounding written marks, serving as an isolation mechanism.

[0057] Based on the arrangement of the magnetic rods 221 in a ring array.

[0058] Furthermore, in this embodiment, a plurality of positioning grooves 2301 are formed on the inner ring surface of the magnetic ring 230;

[0059] Each of the positioning grooves 2301 positions one of the magnetic rods 221;

[0060] At least a portion of the flexible connector 210 is disposed within the magnetic ring 230 and is used to press the connecting ends of each of the magnetic rods 221 against the magnetic ring 230.

[0061] Based on this structural design, during the manufacturing process, the connecting ends of each magnetic rod 221 can be placed into their respective positioning grooves 2301 and then placed into the flexible connector 210, which helps to improve production efficiency and reduce manufacturing costs.

[0062] Furthermore, the flexible connector 210 is a flexible connector 210 formed by dripping adhesive.

[0063] In conjunction with the foregoing, during the manufacturing process, the connecting ends of each of the magnetic rods 221 are placed into their respective positioning grooves 2301, and molten adhesive is dripped into the magnetic ring 230. Once the adhesive solidifies, a flexible connector 210 is formed, which facilitates manufacturing and eliminates the need for prefabrication of the flexible connector 210.

[0064] See Figures 1 to 3 In this embodiment, the magnetic writing pen also includes a pen tip structure 300;

[0065] The pen tip structure 300 includes a connecting part 310 and a conical part 320. The connecting part 310 is detachably connected to the pen grip 100. The cone tip of the cone part 320 faces away from the connecting part 310. The cone tip of the cone part 320 has a mounting groove 3201 for mounting the pen tip assembly 200.

[0066] Based on this, firstly, the addition of the pen tip structure 300 makes the magnetic writing pen closer to the shape of an everyday pen, allowing users to use it based on their experience with everyday pens. Secondly, since the connecting part 310 is detachably connected to the pen grip 100, if the pen tip assembly 200 is damaged, the pen tip structure 300 can be removed, leaving the pen grip 100 intact, reducing the number of parts that need to be replaced and lowering the cost of use.

[0067] Furthermore, the pen grip 100 is provided with a plug hole 101;

[0068] The connecting part 310 is inserted into the insertion hole 101;

[0069] The outer peripheral surface of the connecting part 310 is provided with an annular retaining ring, and the inner wall surface of the insertion hole 101 is provided with an annular retaining groove, wherein the annular retaining groove and the annular retaining ring are engaged with each other.

[0070] Therefore, replacement can be achieved simply by plugging and unplugging. Furthermore, the interlocking of the annular groove and the annular retaining ring effectively ensures the reliable connection between the pen tip structure 300 and the pen grip 100.

[0071] In addition, in other embodiments, the outer peripheral surface of the connecting part 310 may be provided with an annular groove, and the inner wall surface of the insertion hole 101 may be provided with an annular retaining ring.

[0072] See Figure 1 and Figure 3 In this embodiment, the magnetic writing pen further includes a magnetizing magnet 400;

[0073] The magnetizing magnet 400 is disposed inside the pen grip 100 and generates a magnetizing magnetic field, which is used to enhance the magnetism of the magnetic rod 221. The magnetizing magnet 400 effectively ensures the magnetism of the magnetic rod 221, thereby ensuring that the magnetic pen achieves the technical effect desired by this invention.

[0074] In other embodiments, the magnetic field used to enhance the magnetism of the magnetic rod 221 can be implemented by an electromagnetic component; specifically, the magnetic pen also includes an electromagnetic component.

[0075] The electromagnetic component is used to generate an electromagnetic magnetic field, which enhances the magnetism of the magnetic rod 221. Similarly, the electromagnetic component effectively ensures the magnetism of the magnetic rod 221, thereby ensuring that the magnetic pen achieves the technical effect desired by this invention.

[0076] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
