Description

Technical Field

[0001] The utility model relates to the technical field of calligraphy and painting tools, in particular to a magnetic suction writing brush. Background Art

[0002] As a traditional Chinese writing tool, the brush needs to be cleaned after the ink is dipped in ink and writing is completed. If the brush tip is not cleaned and becomes dry and solidified, the brush tip must be soaked again before use, which is cumbersome and time-consuming; the pen holder is long and inconvenient to carry. The "A Brush Writing Pen Holding Trainer" (Patent No.: CN220220210U) publicly authorized on December 22, 2023 uses magnet blocks installed on the upper end of the brush mounting seat and the lower end of the pen holder fixing rod to attract the brush tip and the pen holder, a positioning shaft is provided at the lower end of the pen holder fixing rod, and a socket is provided at the upper end of the brush mounting seat, and the positioning shaft is inserted into the socket to enhance stability; the separation of the brush tip and the pen holder of the patent also requires holding the brush tip and the pen holder with both hands for operation, which is inconvenient to operate, and the hand holding the brush tip is easy to contaminate the ink; due to the presence of the positioning shaft and the socket, when replacing the brush tip, it is impossible to use a more labor-saving bend at the disconnection point. The nib and the pen holder cannot be separated by bending or sliding horizontally, but must be forcibly pulled apart along the axial direction of the brush pen holder, which requires overcoming a large axial magnetic attraction. The axial separation of magnetic attraction is the most laborious and difficult, which can easily result in the situation that the magnetic attraction is too small to ensure the stability of the nib during writing, and the magnetic attraction is too large to pull apart. In addition, the main purpose of our hope that the nib and the pen holder can be separated and replaced is because the pen holder can be used for a long time and the consumable nib can be easily replaced and the damaged nib can be discarded. The most commonly used magnets are fragile and easy to corrode. It is appropriate to use magnets for consumable nibs, but if magnets are used in the pen holder, it is easy to cause the magnet to be damaged first before the pen holder is damaged, and the entire pen holder has to be discarded, resulting in unnecessary waste, thus losing the meaning of separating the nib and the pen holder. The pen holder adopts a magnet structure, which is more complicated and costly than the use of ferromagnetic materials. So far, most of the brushes on the market still have inseparable nibs and pen holders. The nib is a consumable that is easy to break, but the pen holder is almost never damaged. It is too wasteful to discard the nib and the pen holder together just because the nib is unusable. During the use of the brush, it is necessary to clean the brush if it is not used for a short period of time, otherwise the brush will easily dry out and become hard. Although there are now moisturizing storage boxes for brushes, the storage of the brushes is still inconvenient and not ideal. Only by solving the above-mentioned pain points in the use of brushes can calligraphers and calligraphy enthusiasts who use brushes have a better writing experience. Utility Model Content

[0003] The purpose of the utility model is to provide a magnetic suction brush to solve the problems raised in the above background technology.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The first suction body can be magnetically connected to the second suction body to firmly suck the pen head onto the pen holder, and the positioning convex teeth match the positioning concave teeth, so that there will be no sliding dislocation between the pen holder and the pen head, thereby ensuring the normal use of the magnetic suction brush;

[0013] 2. The pen tip moisturizing box is provided with the pen tip. The pen tip is kept in the special pen tip moisturizing box for moisturizing and standby use, and the pen holder is placed in the pencil case for storage.

[0014] 3. When not in use, you only need to operate with one hand. Clamp the first suction body into the pen tip clamp of the matching special pen tip moisturizing box, and apply a very small force in the horizontal direction to fold the pen shaft to separate the pen shaft and the pen tip. There is no need to hold the pen tip tightly. This is simple and quick, avoiding the disadvantage of the existing detachable brush that the pen tip needs to be held tightly by hand when separating the pen tip and the pen shaft, which easily causes the hand to be contaminated with ink.

[0015] 4. One of the purposes of the pen tip 1 being easily separated from the pen holder 2 is to allow the consumable pen tip 1 to be easily replaced and discarded, while the pen holder 2 can be used for a long time and matched with different pen tips 1, so that one pen holder can be used for multiple purposes and one pen holder can be used frequently, which is more reasonable and economical.

[0024] Unless otherwise defined, all technical terms used in the embodiments of the present invention have the same meanings as commonly understood by those skilled in the art.

[0025] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] See also Figure 1-4 The utility model provides an embodiment: a magnetic suction brush, including a brush head 1, a pen holder 2 is provided on one side of the brush head 1, the brush head 1 includes a pen tip 11, a pen holder 12 is provided on one side of the pen tip 11, a first suction body 13 is fixedly provided on the end of the pen holder 12 away from the pen tip 11, the pen holder 2 includes a pen holder body 22, a second suction body 21 is fixedly provided on the end of the pen holder body 22 facing the brush head 1, the first suction body 13 is magnetically connected to the second suction body 21, and under the action of magnetic attraction, the first suction body 13 attracts the second suction body 21 to realize the connection between the brush head 1 and the pen holder 2.

[0027] The first suction body 13 includes a first suction body shell 131. The interior of the first suction body shell 131 is a hollow structure. A magnetic structural part 132 is fixedly provided inside the first suction body shell 131. A unidirectional shielding iron sheet 133 is fixedly provided on the bottom surface of the magnetic structural part 132. A plurality of positioning protruding teeth 1311 are provided on the side of the first suction body shell 131 facing the pen body 2. The positioning protruding teeth 1311 are cone-shaped or table-shaped, which is more conducive to the alignment of the convex and concave teeth and the folding of the pen body 2. The function of the unidirectional shielding iron sheet 133 is to shield the magnetic field distributed by the magnetic structural part 132 toward the direction of the pen head 1, generate a stronger unidirectional magnetic field facing the second suction body 21, and protect the magnetic structural part 132 at the same time.

[0028] The second suction body 21 comprises a second suction member 211 . A plurality of positioning concave teeth 212 are disposed on a side of the second suction member 211 facing the pen tip 1 .

[0029] The positioning protruding teeth 1311 match the positioning concave teeth 212, and after the pen holder 2 and the pen tip 1 are attracted, the sliding dislocation between the pen holder 2 and the pen tip 1 on the attraction interface can be prevented;

[0030] The magnetic structural part 132 is a magnetic structural part, and the second suction component 211 is a ferromagnetic structural part. The magnetic structural part 132 is intended to adopt neodymium iron boron magnets. Neodymium iron boron magnets have excellent magnetic properties and moderate cost for magnetic suction brushes. The magnetic structural part 213 can also adopt an electromagnet structure. A gap of 0.2 to 2 mm is designed between the second suction component 211 and the upper surface of the first suction body shell 131, which can avoid direct contact and collision between the second suction component 211 and the first suction body shell 131, and can greatly extend the service life of the magnetic structure.

[0031] One of the purposes of the pen tip 1 being able to be easily separated from the pen body 2 is that the consumable pen tip 1 can be easily replaced and discarded, while the pen body 2 can be used for a long time; the most commonly used magnets, such as neodymium iron boron magnets, are fragile and easy to corrode, so it is advisable to use a magnetic structure on the first attraction body 13 of the pen tip 1, and a ferromagnetic structure on the second attraction body 21 of the pen body 2; if a magnetic structure is used on the second attraction body 21 of the pen body 2, it is easy to cause the pen body 2 to be damaged but the magnet alone is damaged first, and the entire pen body 2 has to be discarded, causing unnecessary waste. It is more matching and reasonable to use more durable ferromagnetic structural parts on the pen body 2 that is used for a long time and magnetic structural parts on the consumable pen tip 1; this is also the practical significance of separating the pen tip 1 and the pen body 2.

[0032] The positioning convex tooth 1311 and the positioning concave tooth 212 can be set to multiple or single. In the case of a single positioning convex tooth 1311 and a single positioning concave tooth 212, the positioning convex tooth 1311 is located at the center of a side of the first suction body shell 131 facing the pen shaft 2, and the positioning concave tooth 212 is located at the center of a side of the second suction body shell 131 facing the pen tip 1, and the two match each other.

[0033] The pen tip 11 includes a pen tip 111, and a pen root 112 is provided at one end of the pen tip 111 facing the pen holder 12. The pen tip 1 is equipped with a pen tip moisturizing box. The pen tip 11 is a pen tip 111 and a pen root 112 connected as one body. The pen root 112 is inserted into a cavity at the lower end of the pen holder 12 and fixed. The pen holder 12 is a hollow or partially hollow cylinder or truncated cone, which is a base for installing and fixing the pen root 112, the pen tip 11 and the first suction body 13, and also has the function of a gradual transition section. The relevant structure of the pen tip moisturizing box has been patented and will not be described in detail here.

[0034] Working principle: When in use, the first suction body shell 131 on the pen head 1 is connected with the second suction body 21 on the pen body 2. Since the first suction body shell 131 is provided with a magnetic structure 132 inside, and the second suction body 21 is made of ferromagnetic material, the first suction body shell 131 is magnetically connected with the second suction body 21, and when connected, the positioning convex teeth 1311 and the positioning concave teeth 212 fit each other. When writing, the pen head 1 and the pen body 2 will not rotate, effectively preventing sliding and dislocation. When the pen tip 1 is to be removed, the second suction body is stuck in the pen tip caliper of the matching special pen tip moisturizing box, and the pen body 2 is folded horizontally with one hand. While the joint surface of the second suction body 21 and the first suction body 13 is gradually pried apart, the suction force between the second suction body 21 and the first suction body 13 is sharply weakened, and the positioning convex teeth 1311 and the positioning concave teeth 212 are disengaged therefrom. The pen body 2 and the pen tip 1 can be separated by force, and the pen tip 1 is left in the special pen tip moisturizing box that is tightly covered and sealed to keep moisturized for use, and the pen body 2 is stored in a pencil case.

[0035] It should be pointed out that, in the present utility model, unless otherwise clearly stipulated and limited, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through another feature between them. Moreover, the first feature being "above", "above" and "above" the second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature includes the first feature being directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
