Technical Field
[0001] The utility model relates to the technical field of paintbrushes, in particular to a closed telescopic paintbrush with an anti-drying pen head. Background Art
[0002] Paintbrushes mainly refer to oil brushes and gouache brushes. Paintbrushes are generally made of coarse animal hair or delicate fibers. A paintbrush consists of a brush body and a brush head. When painting with an oil brush, the brush cap is usually removed and the brush head is used for painting. However, after painting is completed, the brush head will be exposed to the air for a long time, which can easily lead to drying, weathering and hair loss. Hair loss will affect the effect of painting, and the entire brush needs to be replaced, increasing the cost of use.
[0003] In the prior art, the utility model with the authorization announcement number CN201659778U is named: the pen tip anti-drying sealed retractable paintbrush. The device proposed in the patent document is retractable through the pen holder, so it is easy to carry, and the pen tip can be sealed, so it can prevent the pen tip from drying and is easy to use;
[0004] In the prior art, the utility model with the authorization announcement number CN220390814U is named: a paintbrush with a freely retractable pen tip. The device proposed in the patent document includes a fixing block and a mounting block through a mounting mechanism. The fixing block is provided with a mounting groove inside. The surface of the fixing block is slidably connected with a sliding sleeve. The pen tip and the mounting block are designed as one body. The mounting block can be quickly installed in the fixing block through the mounting mechanism. Then, when the pen tip is seriously depilated or damaged, the pen tip can be quickly replaced without replacing the entire paintbrush, thereby reducing the painting cost and greatly improving the practicality of the paintbrush.
[0005] However, although the devices proposed in the above two patent documents can facilitate the retraction of the pen tip into the pen body and seal the pen tip, in actual painting applications, manual operation is required to retract the pen tip into the pen body and then seal the pen tip for protection. Therefore, the user needs to manually operate the pen tip to retract and protect it, and the pen tip is prone to shaking during retraction, causing the dye on the pen tip to splash, which greatly increases the workload of the painter and is not very practical.

[0026] In this embodiment, reference Figure 3 The setting of the fixing plate 201 can facilitate the installation and fixation of the electric push rod 202, and by starting the electric push rod 202, the output end of the electric push rod 202 drives the first transmission plate 203 to rise and fall, so that the first transmission plate 203 pulls the subsequent transmission components through the pulling plate 204, thereby realizing the extension and retraction of the brush head, and the brush head can be retracted to the inside of the pen body 1 for protection, avoiding exposure to the air and causing hair removal drying and damage.
[0027] A power module 3 is installed on the upper surface of the fixed plate 201, and a charging head 4 is installed on the upper end of the pen body 1. By providing the power module 3, it is convenient to provide energy to the electric push rod 202, so that the brush head can be retracted in an electrically powered manner, thereby eliminating the need for the painter to manually retract the brush head into the pen body 1, thereby greatly improving the ease of use of the device and reducing the workload of the painter.
[0028] The outer surface of the upper part of the pen body 1 is sleeved with a first sealing clamping ring 5, and the outer surface of the lower part of the pen body 1 is sleeved with a second sealing clamping ring 6. By providing the first sealing clamping ring 5, it is easier to clamp the sealing protection component to the upper part of the pen body 1 when in use, so as to carry out painting work, and the provision of the second sealing clamping ring 6 can facilitate the sealing protection of the brush head when not in use.
[0029] A detachable sealing cover 7 is sleeved on the lower part of the pen body 1, and the sealing cover 7 is clamped with the second sealing clamping ring 6. By providing the sealing cover 7, the brush head can be better sealed and protected to avoid the brush head being exposed to the air for a long time after use, thereby avoiding hair loss and dryness damage to the brush head, greatly improving the service life of the brush and avoiding frequent replacement of the brush head.
[0030] The outer surface of the pen body 1 is provided with a circular array of anti-slip strips 8, and the anti-slip strips 8 are located at the lower part of the pen body 1. By providing the anti-slip strips 8, it is convenient for the painter to hold the pen body 1 for painting, and the contact friction with the painter can be improved during painting, thereby avoiding slipping during painting and affecting the painting effect.
[0031] Example 2
[0032] like Figure 3-4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the inner wall of the pen body 1 is provided with a slidable sliding ring 205, and the upper surface of the sliding ring 205 is inlaid with a connecting rod 206, the upper end of the connecting rod 206 is fixedly connected to a second transmission plate 207, and the reserved groove on the outer surface of the second transmission plate 207 is hinged to the lower end of the pulling plate 204.
[0033] In this embodiment, reference Figure 3 to Figure 4 The setting of the second transmission plate 207 can drive the connecting rod 206 and the sliding ring 205 to rise synchronously under the pulling of the pulling plate 204, so that the brush head can be retracted to the inside of the pen body 1 for protection through the connecting rod 206, and the brush head can be sealed and protected by the subsequent sealing component to avoid the risk of drying and hair loss caused by contact with the external air, greatly improving the service life of the brush head and avoiding the cost loss of frequent replacement of the brush head.
[0034] A nib body 208 is installed at the lower end of the connecting rod 206, and the nib body 208 is located at the lower part of the pen body 1. By setting the nib body 208, the nib body 208 is connected to the connecting rod 206 in an installation manner, and different nib bodies 208 can be installed or disassembled for use according to needs, thereby greatly improving the applicability and practicality of the overall device.

By setting the slide grooves 209, the slide grooves 209 can facilitate the limited sliding of the sliding ring 205 through the slider 2010, thereby preventing the sliding ring 205 from rotating and deviating during the contraction movement, causing the pen head body 208 to fall off.
[0036] A protective ring 2011 is fixedly connected to the bottom surface of the pen body 1, and the pen head body 208 is located at the inner circle of the protective ring 2011. By setting the protective ring 2011, the sliding ring 205 and other linkage components can be better protected to prevent the sliding ring 205 and other components from falling, thereby greatly improving the stability and practicality of the brush.
[0037] Working principle: When painting with the paintbrush, first, the sealing cover 7 is taken out and the sealing cover 7 is clamped on the upper end of the pen body 1. At this time, the electric push rod 202 is started, and the output end of the electric push rod 202 drives the first transmission plate 203 to move downward, so that the first transmission plate 203 pushes the second transmission plate 207 to move downward through the pulling plate 204, and the second transmission plate 207 pushes the connecting rod 206 and the connecting rod 206 to move downward, thereby pushing the pen head body 208 out of the pen body 1, which is convenient for the painter to enter. The painting work is performed, and after the painting is completed, the electric push rod 202 is started again, and the above steps are reversed, so that the nib body 208 can be retracted to the inside of the pen body 1 for protection, and the sealing cover 7 is removed from the upper end of the pen body 1 and installed to the lower end of the pen body 1, thereby sealing the nib body 208 to avoid the risk of drying and hair loss caused by contact between the nib body 208 and the external air, greatly improving the service life of the nib body 208 and avoiding the cost loss of frequent replacement of the nib body 208.
[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
