Abstract
Description
Technical Field
[0001] This utility model relates to the field of stationery technology, and in particular to a vertical writing magnetic pen and a storage and wiping assembly. Background Technology
[0002] Whiteboards are widely used as a common information writing tool in daily office work, teaching, and presentations. Traditional whiteboard markers usually rely on ink or dry-erasable refills to write and erase temporarily on surfaces such as whiteboards, which has problems such as the ink drying out or leaving residue that is difficult to remove.
[0003] To address these issues, a new type of magnetic pen has emerged in recent years that enables writing through a magnetic structure. These pens create erasable writing by magnetic attraction between the pen tip and a specific magnetically responsive writing surface (such as a whiteboard with a magnetic coating). They offer advantages such as being inkless, environmentally friendly, and easy to clean.
[0004] However, most existing magnetic pens adopt a structure in which the pen barrel and pen tip are set in a straight line on the same axis. When used on a vertically set writing surface (such as a whiteboard), in order to make the pen tip make positive contact with the writing surface, users often need to raise their wrists or adjust the angle of their grip, resulting in an unnatural writing posture and poor user comfort.
[0005] Therefore, there is an urgent need to provide a vertical magnetic writing pen to improve the problems of unnatural writing posture and poor user comfort in existing magnetic pens; at the same time, there is also an urgent need for a storage and erasing component that can store the vertical magnetic writing pen to improve the overall practicality and convenience of writing.

Where there is no conflict, the various features in the embodiments and examples of this utility model can be combined with each other, all of which are within the protection scope of this utility model.
[0039] Firstly, such as Figures 1 to 6 As shown, this utility model provides a vertical writing magnetic pen, which includes a pen barrel 11, a pen head 12, a pen tip 13, and a guide part 14.
[0040] The pen barrel 11 includes a grip portion and an internal magnetic structure (not shown) for forming visible writing marks on a magnetically responsive medium. This magnetic structure can be connected to or extend to the pen tip 13 to produce visible marks on a matching magnetically responsive surface. The magnetic structure can be a permanent magnet, a soft magnetic alloy, a magnetized pen core, a magnetic ink core, or a magnetically conductive component containing high permeability materials. Its arrangement can include embedding along the pen barrel axis, a ring arrangement, or a spiral arrangement. Through optimized polarity design, a stable and controllable magnetic response color rendering effect can be achieved when in contact with a magnetically responsive surface (such as a whiteboard coated with magnetic powder or a magnetic display coating). This structural design allows the vertical writing magnetic pen 1 to form graphic traces on a magnetically responsive medium without the need for traditional ink media, relying on a magnetic field, offering advantages such as environmental friendliness and durability.
[0041] Furthermore, the pen tip 12 is mounted on one end of the pen barrel 11, and the pen tip 12 is inclined relative to the pen barrel 11; the pen nib 13 is mounted on the end of the pen tip 12 away from the pen barrel 11; the guide part 14 is disposed on the side of the pen barrel 11 and / or the side of the pen tip 12, for guiding the user to form a grip posture that conforms to the pen nib 13 perpendicularly contacting the writing surface, so that the pen nib maintains a perpendicular contact state with the writing surface when writing.
[0042] It should be noted that the structure of the guide part 14 is based on ergonomic design principles. By limiting the contact surface or restricted area of the user's fingers, it guides the user to naturally form a specific angle of pen grip under the dual feedback of vision and touch, so that the pen tip 13 can contact the writing surface such as the whiteboard at a basically vertical angle during writing. The "grip posture that conforms to the vertical contact of the pen tip with the writing surface" means that when the user holds the magnetic pen, their fingers are restricted to a specific position by the structure of the guide part 14, so that the pen barrel 11, pen tip 12 and pen tip 13 are in a downward vertical or nearly vertical state, forming a writing contact angle of approximately 90° with the whiteboard surface. This ensures accurate writing trajectory and clear handwriting, and effectively reduces the risk of writing deviation caused by holding the pen at an angle, making the writing posture natural and thus improving writing comfort.
[0043] Furthermore, such as Figure 2 and Figure 3 As shown, the pen tip 12 includes a first segment and a second segment. One end of the second segment is connected to the pen barrel 11, and the other end of the second segment is connected to the first segment. Specifically, the first segment is connected to the second segment and is inclined towards the pen tip 13.
[0044] In one possible implementation, the outer surface of the second segment of the pen tip 12 is inclined relative to the central axis X of the pen barrel 11, such as... Figure 2 and Figure 3As shown, the second segment has a first outer surface 1221 and a second outer surface 1222 that are arranged opposite to each other. The first outer surface 1221 and the second outer surface 1222 of the second segment form a first angle A and a second angle B with the central axis X of the pen barrel 11, respectively. The first angle A and the second angle B can be the same, for example, the first angle A and the second angle C can both be set to 5.2°, or they can be different, but the pen tip 13 is always positioned within the area between the first boundary line and the second boundary line defined by the extension of the first outer surface 1221 and the second outer surface 1222 of the second segment along the central axis of the pen barrel 11, that is, the first boundary line and the second boundary line are parallel to the central axis. For example, if the pen tip 13 is bent, the pen tip 13 connected to the first segment will not exceed the boundary line parallel to the central axis, so that the pen tip 13 can be inserted into and stored in the storage part 21 of the wiping component 2, avoiding protrusion outside the component, ensuring structural strength, preventing breakage, and ensuring stable and safe storage.
[0045] It should be noted that the first outer surface 1221 and the second outer surface 1222 are relative to each other. Figure 2 or Figure 3 In terms of its Figure 2 and Figure 3 Specifically, it is located above and below the central axis X, and the first boundary line Y and the first boundary line Z are... Figure 2 and Figure 3 They are located above and below the central axis X, respectively. The boundary line extends from the connection between the second segment 122 and the pen barrel 11 towards the pen tip 13 and is parallel to the central axis X of the pen barrel 12, such that the first boundary line Y and the second boundary line Z form a first angle A and a second angle B with the first outer surface 1221 and the second outer surface 1222, respectively, that is, the first boundary line Y and the first boundary line Z are parallel to the central axis.
[0046] Furthermore, the outer diameter of the second segment gradually decreases from the connection end with the pen barrel 11 towards the connection end with the first segment. This design achieves a lightweight pen tip structure and a visually harmonious transition, enhancing the overall aesthetics and providing a more natural hand transition experience during gripping or writing, thus improving comfort and stability.
[0047] In one embodiment, as shown in the figure Figure 2 and Figure 3As shown, the first segment extends obliquely towards the pen tip 13 from the connection point with the second segment, and forms a third angle C between its extension segment and the central axis X of the pen barrel 11. That is, the first segment forms a third angle C with the central axis X of the pen barrel 11 at the first connection part 123. Specifically, the third boundary line P extending from the first connection part 123 away from the pen barrel 11 parallel to the central axis forms the third angle C, which is used to describe the spatial relationship between the oblique direction of the first segment and the overall pen barrel axis.
[0048] Furthermore, the connection between the first segment and the second segment (i.e., the second connection 124) forms a fourth angle D, which is typically an obtuse angle, to define the bending angle between the first segment and the second segment. This structure ensures that the pen tip 13 is located within the geometric range defined by the extension direction of the pen barrel 11, facilitating insertion into the storage portion 21 of the wiping component body 22 of the wiping component 2, and enhancing the natural vertical writing experience when holding the pen. The third angle ranges from 10° to 60°, preferably from 15° to 40°, and more preferably from 25°, 30°, or 35°. This angle range conforms to the natural downward writing posture of the human body and is also suitable for forming a more natural angle with the magnetic whiteboard. The fourth angle D ranges from 130° to 179°, and more preferably from 150° to 175°. This preferred angle range ensures that the structure is only slightly tilted, suitable for a natural pen grip. Specifically, it can be 174.8°. This angled structure helps to make the pen tip tilted overall, thus facilitating the pen tip to make vertical contact with the writing surface under a natural pen grip. Furthermore, the fourth angle D can specifically be 174.8°. This angle setting effectively balances grip comfort and writing stability, improving the overall writing experience. By setting the third angle to an acute angle and the fourth angle to an obtuse angle, while maintaining the simplicity of the pen barrel and pen tip structure, the pen tip is made to contact the writing surface in a nearly vertical direction when held naturally. This helps to improve the user's pen grip angle and enhance the accuracy and stability of writing.
[0049] It should be noted that the selection of the third angle C and the fourth angle D must ensure that the pen tip 13 connected in the first segment does not exceed the area of the boundary line parallel to the central axis of the first angle A and the second angle B, so as to facilitate the pen tip being neatly inserted into the storage compartment. Furthermore, the third angle C and the fourth angle D are relative... Figure 2 and Figure 3 The angle formed in terms of direction, the fourth angle D is the angle formed by the connection of the first segment and the second segment on the side away from the guide part 14.
[0050] Furthermore, the first segment is inclined compared to the second segment and the pen barrel 11, with bends at both ends. This not only ensures that the pen tip 13 can be placed into the storage part 21 of the wiping component body 22 after bending, but also keeps the length of the pen head 12 constant. The leverage force is small, allowing the pen tip 13 to make vertical contact with the writing surface in a natural grip posture. This improves the discomfort of the grip angle caused by the traditional coaxial design, thereby enhancing the naturalness of the writing posture and the comfort of use. It also ensures structural strength and prevents breakage.
[0051] Furthermore, such as Figure 6 As shown, at least part of the outer diameter of the first segment gradually decreases in the direction toward the pen tip 13. The first segment is provided with a chamfered surface 1211 and a connecting portion 1212 at one end near the pen tip 13. The connecting portion 1212 is used to connect the pen tip 13. The chamfered surface 1211 is formed by oblique cutting from the side near the pen tip 13 toward the direction away from the pen tip 13.
[0052] Preferably, the connecting part 1212 is a through hole structure opened on the beveled surface 1211, which facilitates the insertion and fixation of the pen tip 13 and ensures its stability. By setting a gradually decreasing outer diameter structure, combined with the inclined transition design of the beveled surface 1211, a natural connection can be achieved visually and structurally, which helps to reduce the structural thickness and weight of the pen tip area, optimize the force state of the front end, and further improve the operability and comfort when writing.
[0053] In addition, the beveled surface 1211 can provide a beveled guide surface for subsequent injection molding or pen tip 13 insertion, simplifying the assembly process, while enhancing the connection between the connecting part 1212 and the pen tip 13, and improving the overall structural strength and stability of use.
[0054] In one embodiment, such as Figures 1 to 6 As shown, the vertical writing magnetic pen is provided with a guide part 14 to guide the user's fingers to achieve natural positioning and stable contact when holding it.
[0055] The guide portion 14 is disposed on the side of the pen barrel 11 and / or the pen tip 12, for example, in a region of the pen barrel 11 near the pen tip 13, extending in the direction toward the pen tip; or on the outer surface of a region of the second segment of the pen tip 12. The guide portion 14 can be configured as a raised structure or a groove structure according to design needs to meet the usage needs of different users for finger fit and anti-slip.
[0056] In one specific embodiment, the guide portion 14 is a raised rib structure, for example, as shown in the figure. Figure 1The raised arrow shown extends along the inclined direction of the pen tip 12 and its protrusion height can be from 0.5 mm to 2 mm. This structure forms a prominent contact surface that naturally conforms to the index finger or thumb when the user holds the pen, improving the stability and comfort of the grip.
[0057] In another embodiment, the guide portion 14 is a groove structure, such as a V-shaped groove or a U-shaped groove, with a preferred recess depth of 0.3 mm to 1.5 mm and a groove width of 1 mm to 5 mm. This structure is used to restrict finger sliding, forming a limiting area, so that the user can form a fixed pen-holding posture during repeated use, thereby improving the consistency of usage habits and writing accuracy.
[0058] The aforementioned guide section 14 can be optimized according to ergonomics, making the pen-holding posture more natural, especially suitable for vertical writing scenarios, effectively improving writing comfort, accuracy and fatigue control during long-term use.
[0059] It should be noted that the guide part 14 is specifically set on the side of the pen barrel 11 and / or the pen tip 12 away from the pen tip 13 (i.e., the writing end). With this setting, a clear finger contact guide area can be formed when the user holds the pen barrel 11, so that the user can quickly achieve finger positioning every time he holds the pen, thereby forming a more consistent and stable pen grip posture. Especially when facing vertical writing scenarios such as whiteboards, it can effectively guide the fingers to maintain a suitable tilt angle, enabling the user to make more natural posture adjustments and continuous writing control when writing vertically on the writing surface of the whiteboard, thereby improving the overall writing efficiency and writing quality.
[0060] In one embodiment, the pen barrel 11 has an eraser 15 at the end away from the pen tip 13. The eraser 15 includes a magnetic sleeve 151, a magnet 152, and a felt 153. The magnetic sleeve 151 is used to fix the magnet 152 and keep the magnetic orientation of the magnet 152 stable to maintain the adsorption and erasing functions of the eraser 15. The felt 153 is disposed on the outside of the magnetic sleeve 151 of the eraser 15 to provide friction and feedback during erasing, and to disturb the writing area affected by magnetic development, so that the magnetic writing marks formed can be removed.
[0061] In summary, traditional magnetic writing pens typically have the pen tip and pen barrel coaxially aligned. Users must adjust their wrist angle to ensure the pen tip makes perpendicular contact with the writing surface, which can easily lead to an unnatural writing posture. The vertical magnetic writing pen 1 provided in this embodiment of the invention, by tilting the pen tip 12 relative to the pen barrel 11 and providing a guide part 14 on the side of the pen barrel 11 and / or the pen tip 12, guides the user to form a reasonable pen-holding posture, allowing the pen tip 13 to naturally and perpendicularly contact the writing surface of the whiteboard 3, thereby improving writing accuracy and user comfort.
[0062] At the same time, by combining the internal magnetic structure with the writing medium made of specific responsive materials, it can replace the non-contact ink output method. Without the need for inkjet or liquid injection, the writing content can be formed by the action of magnetic field, ensuring clean writing, environmental protection, and strong reusability. It is especially suitable for natural writing at vertical or upward angles.
[0063] Secondly, such as Figures 7 to 9 As shown, this utility model provides a storage and wiping assembly 2, which includes a wiping assembly body 22 and the vertical writing magnetic pen described in the first aspect above. The wiping assembly body has a storage portion 21 for detachably accommodating and fixing the vertical writing magnetic pen 1 described in the first aspect. That is, the storage and wiping assembly 2 includes the vertical writing magnetic pen 1 and the wiping assembly body 22 having a storage portion 21 for accommodating the vertical writing magnetic pen 1.
[0064] The storage part 2 is a through-hole structure that passes through the wiping component body 22 of the storage wiping component 2. The vertical writing magnetic pen 1 can be stored in the storage wiping component body 22 through the through-hole structure, which is convenient for fixing and carrying.
[0065] In addition, the storage and wiping assembly 2 also has a wiping part, which can wipe away the writing content of the vertical writing magnetic pen 1 on the writing surface.
[0066] The storage and wiping component 2 of this utility model has a dedicated storage design, which reduces the risk of component loss and solves the implicit need of users for "convenient component management". Compared with the erasing area of the eraser 15 at the end of the pen barrel 11, the matching storage and wiping component has higher erasing efficiency and improves the user experience.
[0067] In another embodiment, the wiping assembly 2 may also include a connecting part, such as a magnet, through which the wiping assembly body, together with the vertical magnetic writing pen stored in the wiping assembly body, can be connected to the whiteboard to form a writing device that is easy to carry.
[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
