[0076] This example provides a writing pen, such as Figures 1-2 As shown, the writing pen includes a pen barrel 1, a decorative component 2, a reset component 3, a pressing component 4, and a refill component 5. The pen barrel 1 is provided with a positioning through hole 110 (e.g., ...). Figure 7 (As shown); Decorative component 2 is provided with an ejection ramp 2221 and a reset ramp 2222; Reset component 3 is slidably disposed inside the pen barrel 1, and a reset part 3111 is provided on the side of the reset component 3 facing the decorative component 2; Pressing component 4 is provided with a pushing part 411 on the side of the decorative component 2; Pen refill component 5 is disposed inside the pen barrel 1 and passes through the reset component 3 and the pressing component 4. The pressing component 4 is configured to drive the pen refill component 5 to move along the axial direction of the pen barrel 1, causing the pushing part 411 to contact and engage with the ejection ramp 2221, and pushing the decorative component 2 out of the positioning through hole 110. The decorative component 2 can also press against and reset component 3, allowing the reset component 3 to move towards the pressing component 4 and relative to the pen barrel 1. The reset part 3111 contacts and engages with the reset ramp 2222, and pushes the decorative component 2 back into the positioning through hole 110.

[0077] When needed, such as Figures 3-4 As shown, when the user presses the pressing component 4, the pressing component 4 drives the pen refill component 5 to move along the axial direction of the pen barrel 1. After the pressing component 4 moves a certain distance, the pushing part 411 of the pressing component 4 abuts against the ejection inclined surface 2221 of the decorative component 2. The force exerted by the pushing part 411 on the ejection inclined surface 2221 can be decomposed into a first component force along the axial direction of the pen barrel 1 and a second component force along the radial direction of the pen barrel 1. Under the action of the second component force, the decorative component 2 is pushed through the positioning through hole 110 along the radial direction of the pen barrel 1, so that the decorative component 2 extends out of the positioning through hole 110.

[0078] At the same time, the reset inclined surface 2222 of the decorative component 2 and the reset part 3111 of the reset component 3 make contact and cooperate. The force applied by the reset inclined surface 2222 to the reset part 3111 can be decomposed into a third component force along the axial direction of the pen barrel 1 and a fourth component force along the radial direction of the pen barrel 1. Under the action of the third component force, the reset component 3 is pushed to move and the reset component 3 is provided with a reset pre-pressure.

[0079] After the pen refill assembly 5 extends out of the pen barrel 1, the pressing assembly 4 is stopped. Under its own restoring force, the reset assembly 3 will push the decorative assembly 2 in the opposite direction. The reset part 3111 of the reset assembly 3 abuts against the reset inclined surface 2222 of the decorative assembly 2, causing the decorative assembly 2 to retract to the positioning through hole 110 along the radial direction of the pen barrel 1.

[0080] The writing pen provided in this embodiment, when the pressing component 4 presses the pen core assembly 5 to eject the core, the pushing part 411 of the pressing component 4 contacts and cooperates with the ejection inclined surface 2221, and the decorative component 2 extends out of the positioning through hole 110. The resetting part 3111 contacts and cooperates with the resetting inclined surface 2222, and the decorative component 2 retracts into the positioning through hole 110. This realizes the linkage between the pressing and ejection of the core and the decorative component 2, so that the decorative component 2 can jump with the protrusion and retraction of the pen core assembly 5, simulating the jumping effect of the decorative component 2, enhancing the fun and interactivity of the writing pen, and meeting the diverse usage needs of users.

[0081] The pen barrel 1, pen refill assembly 5, reset assembly 3, decorative assembly 2, and pressing assembly 4 are described below.

[0082] In one embodiment, such as Figures 5-7 As shown, the pen barrel 1 includes a main body 11, which is similar in shape to a cylindrical structure. The main body 11 is hollow and has a receiving cavity, which provides space for the pen refill assembly 5, the reset assembly 3, the decorative assembly 2, and the pressing assembly 4.

[0083] The positioning through hole 110 is provided in the main body 11. The inner wall shape of the positioning through hole 110 is adapted to the outer wall contour of the decorative component 2, and can provide a guide path for the extension and retraction of the decorative component 2.

[0084] In one embodiment, the pen barrel 1 further includes a tip sleeve 12. Along the axial direction of the pen barrel 1, one end of the tip sleeve 12 is connected to the main body 11, and the other end is provided with an opening. The pen refill assembly 5 extends out of the opening to allow the user to write. The pen refill assembly 5 retracts from the opening to facilitate storage of the pen refill assembly 5.

[0085] In one embodiment, such as Figure 8 As shown, the pen refill assembly 5 includes a pen refill 51 and an elastic element 52. The pen refill 51 passes through the pen barrel 1 and can extend out of the opening. The elastic element 52 can be a cylindrical spring. The elastic element 52 is sleeved on the outside of the pen refill 51 and is disposed between the tip sleeve 12 and the pen refill 51, for the pen refill 51 to return to its original position after being pressed.

[0086] In one embodiment, such as Figures 8-10 As shown, the writing pen also includes a support member 6, which is disposed inside the pen barrel 1 and sleeved on the outside of the pen refill assembly 5. The reset assembly 3 is disposed between the support member 6 and the decorative assembly 2.

[0087] The support member 6, also known as the fixing ring, is fixed in position relative to the pen barrel 1. It provides a support position for the reset assembly 3. When the decorative assembly 2 pushes the reset assembly 3, the reset assembly 3 comes into contact with the support member 6. Both ends of the reset assembly 3 abut against the support member 6 and the decorative assembly 2 respectively, allowing the reset assembly 3 to generate a reset preload under pressure. Simultaneously, the support member 6 provides a stable installation reference for the reset assembly 3, limiting its radial displacement during axial sliding. This ensures a more precise fit and smoother movement between the reset assembly 3 and the decorative assembly 2, reducing jamming or failure caused by component vibration.

[0088] In one embodiment, the inner wall of the pen barrel 1 is provided with a first protrusion 111 (e.g., ...). Figure 7 As shown), the outer wall of the support member 6 is provided with a second protrusion 611 (as shown). Figure 9 As shown, the first protrusion 111 abuts against the second protrusion 611. Exemplarily, the second protrusion 611 is disposed on the fixing sleeve 61. This arrangement keeps the distance between the support member 6 and the positioning through hole 110 of the pen barrel 1 within a certain range, thus limiting the axial movement of the support member 6 and preventing the reset assembly 3 and decorative assembly 2 from reliably contacting due to a large displacement of the support member 6.

[0089] In some embodiments, the first protrusion 111 and the second protrusion 611 may be annular bosses, and the first protrusion 111 and the second protrusion 611 are continuous structures, which increases the contact area between the first protrusion 111 and the second protrusion 611, improves the fixing effect of the support member 6 relative to the pen barrel 1, and thus provides a stable supporting force for the reset assembly 3.

[0090] In some other embodiments, the support member 6 can be directly fixed to the inner wall of the pen barrel 1. For example, the support member 6 can be connected to the pen barrel 1 by means of threads, snap-fit, etc.; or the support member 6 and the pen barrel 1 can be integrally formed.

[0091] In one embodiment, such as Figure 8 , Figures 11-13 As shown, the reset assembly 3 includes a slider 31, which is slidably disposed within the pen barrel 1. A reset part 3111 is disposed on the side of the slider 31 facing the decorative assembly 2. The slider 31, as a component that directly cooperates with the decorative assembly 2, transmits the reset force through the reset part 3111.

[0092] In one embodiment, the reset assembly 3 includes a reset member 32, which is disposed between the support member 6 and the slider 31.

[0093] The reset member 32 can be a cylindrical spring. The reset member 32 is positioned between the support member 6 and the sliding member 31. The reset member 32 can store and release elastic potential energy to provide power for the reset action. Specifically, when the sliding member 31 is pressed by the decorative component 2, the sliding member 31 compresses the reset member 32. Then, under its own restoring force, the compressed reset member 32 pushes the sliding member 31 to reset. Furthermore, through the cooperation between the reset part 3111 of the sliding member 31 and the reset inclined surface 2222 of the decorative component 2, the action of the decorative component 2 retracting into the positioning through hole 110 is made smoother, avoiding problems such as the decorative component 2 getting stuck or not resetting properly due to the deviation in the transmission of reset force.

[0094] In one embodiment, such as Figure 8 , Figures 9-10 As shown, the support member 6 includes a fixed sleeve 61, wherein the fixed sleeve 61 provides a fixed force reference for the reset member 32, avoiding radial displacement or tilting during compression or rebound of the reset member 32, and ensuring that the elastic force of the reset member 32 can act on the sliding member 31 along the axial direction of the pen barrel 1.

[0095] In one embodiment, the support member 6 further includes a first positioning post 62, which is disposed within the fixing sleeve 61, and the reset member 32 is sleeved on the first positioning post 62 and disposed between the fixing sleeve 61 and the first positioning post 62.

[0096] The first positioning post 62 provides an installation position for the reset component 32 and also limits its movement, preventing it from shifting radially along the pen barrel 1 during compression or rebound, ensuring that the reset component 32 always extends and retracts axially along the pen barrel 1. Simultaneously, the fixing sleeve 61 and the first positioning post 62 together form an axial spatial limit, restricting the installation position and extension range of the reset component 32, preventing it from losing its elasticity due to excessive compression or from excessively rebounding out of its preset working area. This method achieves dual limiting of the reset component 32, improving its positioning accuracy and reliability.

[0097] The fixing sleeve 61 and the first positioning post 62 are integrally formed, which reduces the number of parts assembly steps and lowers production costs.

[0098] In one embodiment, such as Figure 8 , Figures 11-13As shown, the slider 31 includes a sliding sleeve 311, which can slide within the pen barrel 1. A reset part 3111 is disposed at the end of the sliding sleeve 311 facing the decorative component 2. Specifically, the reset inclined surface 2222 of the decorative component 2 contacts the reset part 3111, pushing the sliding sleeve 311 to slide within the pen barrel 1, thereby compressing the reset member 32. Under its own restoring force, the compressed reset member 32 can move towards the decorative component 2 through the sliding sleeve 311. The reset part 3111 of the sliding sleeve 311 contacts and engages with the reset inclined surface 2222 of the decorative component 2, thereby causing the decorative component 2 to reset.

[0099] In one embodiment, the reset part 3111 is a chamfer provided at the end of the sliding sleeve 311.

[0100] Specifically, the chamfer angle is set according to the angle of the reset slope 2222 to achieve a tight fit between the reset slope 2222 and the chamfer, avoiding local wear or jamming caused by insufficient contact area. When the reset component 32 pushes the sliding sleeve 311 to move axially, the chamfer can slide smoothly along the reset slope 2222 of the decorative component 2. The component force between the slopes evenly drives the decorative component 2 to retract into the positioning through hole 110, ensuring the smoothness of the extension and retraction of the decorative component 2. At the same time, there is no need to add independent reset protrusions, buckles or other structures to the sliding sleeve 311. The chamfer can be formed simply by cutting and grinding the end of the sliding sleeve 311, simplifying the overall structure of the sliding sleeve 311 and reducing the processing difficulty and production cost of the sliding sleeve 311.

[0101] In one embodiment, such as Figure 8 , Figures 11-13 As shown, the sliding member 31 also includes a second positioning post 312, which is disposed on the side of the sliding sleeve 311 away from the decorative component 2. The reset member 32 is sleeved on the outside of the second positioning post 312 and can abut against the sliding sleeve 311.

[0102] For example, the second positioning post 312 provides a guiding reference for the assembly of the reset member 32. During assembly, the reset member 32 only needs to be fitted onto the second positioning post 312 to quickly achieve coaxial positioning of the reset member 32 and the sliding sleeve 311, without the need for manual adjustment of the relative positions of the reset member 32 and the sliding sleeve 311, thus simplifying the assembly process. The reset member 32 is fitted onto the outside of the second positioning post 312 and abuts against the end face of the sliding sleeve 311, forming a surface contact force state, which improves the uniformity of force between the reset member 32 and the sliding sleeve 311.

[0103] In addition, the two ends of the reset member 32 are respectively inserted through the first positioning post 62 and the second positioning post 312. The first positioning post 62 and the second positioning post 312 play a dual positioning role for the reset member 32, further preventing the reset member 32 from tilting or shifting during compression or rebound, and ensuring that the reset member 32 always extends and retracts along the axial direction of the pen barrel 1, so as to ensure the smoothness and stability of the sliding of the entire reset assembly 3.

[0104] In one embodiment, such as Figures 14-16 As shown, the decorative component 2 includes a decorative element 21, which passes through the positioning through hole 110 and slides in cooperation with the positioning through hole 110.

[0105] The decorative part 21 can be shaped like a heart. The decorative part 21 extends and retracts relative to the positioning through hole 110, so that the decorative part 21 can bounce with the exposure and retraction of the pen core 51 to simulate the process of a heart beating, thereby increasing the fun and interactivity of the writing pen.

[0106] In one embodiment, such as Figure 14 As shown, the decorative component 2 also includes a connector 22, which includes a mounting portion 221. The mounting portion 221 is connected to the decorative component 21, so that the connector 22 and the decorative component 21 form an integral structure.

[0107] Specifically, such as Figures 16-17 As shown, the positioning through hole 110 includes a first through hole 1101 and a second through hole 1102. The first through hole 1101 is heart-shaped, and its inner wall shape matches the outline shape of the decorative piece 21. The decorative piece 21 is located within the first through hole 1101 and can extend and retract relative to it. The second through hole 1102 is slightly smaller than the first through hole 1101. The first through hole 1101 and the second through hole 1102 are connected, and the step formed between them serves to limit the decorative piece 21. The size and shape of the second through hole 1102 are adapted to the connecting piece 22. As the decorative piece 21 slides within the first through hole 1101, the connecting piece 22 passes through the second through hole 1102 and extends and retracts relative to it.

[0108] In one embodiment, such as Figure 14 , Figures 18-20 As shown, the decorative part 21 has a mounting groove 211 facing the connector 22, and the mounting part 221 is provided in the mounting groove 211. One of the inner wall of the mounting groove 211 and the outer wall of the mounting part 221 is provided with a snap-fit ​​part 212, and the other is provided with a snap-fit ​​mating part 2211.

[0109] For example, the inner wall of the mounting groove 211 is provided with a snap-fit ​​portion 212, which may be a protrusion. The mounting portion 221 of the decorative part 21 is provided with a snap-fit ​​mating portion 2211, which may be a snap-fit. The decorative part 21 and the connector 22 are fixed by snapping the snap-fit ​​portion 2211 onto the snap-fit ​​mating portion 2212.

[0110] In one embodiment, such as Figures 20-21 As shown, the connector 22 also includes a drive unit 222, and the push-out inclined surface 2221 and the reset inclined surface 2222 are disposed on both sides of the drive unit 222 along the radial direction of the pen barrel 1.

[0111] Specifically, the push-out slope 2221 and the reset slope 2222 of the drive unit 222 correspond to the push part 411 of the pressing component 4 and the reset part 3111 of the reset component 3, respectively. This allows the two key actions of pushing the decorative piece 21 out and pulling the decorative piece 21 back to be concentrated on the same drive unit 222, giving the drive unit 222 the function of centralized force transmission. Simultaneously, the push-out slope 2221 and the reset slope 2222 are respectively located on both sides of the drive unit 222 along the radial direction of the pen barrel 1. This functional partitioning design avoids interference between the processes of pushing the decorative piece 21 out and pulling the decorative piece 21 back, and ensures the synchronicity of the movement of the decorative piece 21 and the drive unit 222.

[0112] In one embodiment, such as Figure 20 , Figure 22 As shown, the connector 22 also includes a limiting part 223, which is disposed between the mounting part 221 and the driving part 222. The limiting part 223 can increase the connection strength between the mounting part 221 and the driving part 222, and can also be referred to as a reinforcing rib. The limiting part 223 passes through the second through hole 1102 and can move with the extension and retraction of the decorative part 21.

[0113] In one embodiment, the reset component 3 is provided with a limiting groove 3112 (e.g., Figure 13 As shown, the limiting part 223 passes through the limiting groove 3112 and is used to limit the rotation of the reset assembly 3 relative to the pen barrel 1.

[0114] For example, the limiting groove 3112 is provided on the side of the slider 31 facing the decorative component 2, and the limiting part 223 passes through the limiting groove 3112 to form a circumferential constraint, which restricts the slider 31 from radial rotation during the sliding along the axial direction of the pen barrel 1, and ensures that the reset part 3111 of the slider 31 always maintains a preset angular alignment relationship with the reset inclined surface 2222 of the drive part 222, so as to avoid poor contact caused by the rotation of the slider 31.

[0115] In one embodiment, such as Figure 8 , Figures 23-24 As shown, the pressing assembly 4 includes a pressing member 41, which can also be referred to as a rotating wheel. The pressing member 41 is at least partially disposed inside the pen barrel 1 and can slide relative to the pen barrel 1. The pressing member 41 is sleeved on the outside of the pen refill assembly 5. The pushing part 411 is disposed on the side of the pressing member 41 facing the decorative assembly 2. The pushing part 411 is provided with a pushing inclined surface 4111, and the pushing inclined surface 4111 and the pushing inclined surface 2221 are in contact with each other.

[0116] The pressing element 41 is fitted onto the outside of the pen refill assembly 5, ensuring that the pressing action directly drives the axial movement of the pen refill assembly 5. Simultaneously, the pushing slope 4111 of the pushing part 411 and the ejection slope 2221 of the decorative component 2 form a sloped engagement, efficiently converting the axial force of the pressing element 41 into a component force driving the radial extension of the decorative component 2. In this way, pressing simultaneously ejects the pen refill 51 and triggers the ejection of the decorative component 2, enhancing the enjoyment of writing. Furthermore, the contact engagement between the pushing slope 4111 and the ejection slope 2221 is a progressive force application process, resulting in more uniform pressing pressure and improved user experience.

[0117] The pen barrel 1 is equipped with a guide rail, and the pressing member 41 can move along the guide rail in the axial direction of the pen barrel 1 to ensure that the pressing member 41 moves in the axial direction of the pen barrel 1 during the pressing process of the pen core 51. The end of the guide rail facing the pen core 51 is provided with a toothed groove, and the outside of the pressing member 41 is provided with gear teeth. When the pressing member 41 moves to the end of the guide rail, the pressing member 41 can rotate relative to the pen barrel 1, so that the gear teeth engage with the toothed groove. This restricts the position of the pen core 51 relative to the pen barrel 1 by the pressing member 41, preventing the pen core 51 from retracting into the pen barrel 1 during the user's writing process.

[0118] In one embodiment, the pressing component 4 further includes a lifting head 42, which is at least partially disposed within the pen barrel 1 and is slidable relative to the pen barrel 1. The lifting head 42 is sleeved on the outside of the pressing member 41 and located between the pressing member 41 and the pen barrel 1.

[0119] For example, the lifting head 42 is sleeved on the outside of the pressing member 41, which can increase the pressing contact area and make it easier for the user to press the pressing member 41 through the lifting head 42. At the same time, the lifting head 42 can prevent external dust, moisture and other impurities from entering the gap between the pressing member 41 and the pen barrel 1, reduce the corrosion of the internal structure by contaminants and extend the service life of the pressing assembly 4.

[0120] The writing pen provided in this embodiment is used as follows:

[0121] When needed, the user presses the lifting head 42 of the pressing component 4. The lifting head 42 drives the pen core assembly 5 to move along the axial direction of the pen barrel 1 through the pressing member 41. After moving a certain distance, the pushing part 411 of the pressing member 41 abuts against the pushing inclined surface 2221, pushing the decorative component 2 through the positioning through hole 110 along the radial direction of the pen barrel 1, so that the decorative component 21 protrudes from the positioning through hole 110.

[0122] At the same time, the reset inclined surface 2222 of the decorative component 2 and the reset part 3111 of the reset component 3 make contact and cooperate. The force applied by the reset inclined surface 2222 to the reset part 3111 pushes the sliding member 31 to move and compresses the reset member 32, and provides a reset pre-pressure for the reset member 32.

[0123] After the pen refill assembly 5 extends out of the pen barrel 1, the pressing of the lifting head 42 is stopped. Under its own restoring force, the reset member 32 pushes the decorative component 2 in the opposite direction through the sliding member 31. The reset part 3111 of the sliding member 31 abuts against the reset inclined surface 2222 of the decorative component 2, causing the decorative component 21 to retract along the radial direction of the pen barrel 1 to the positioning through hole 110. Thus, the decorative component 21 completes one exposure and reset action, achieving the linkage between pressing the pen refill and the decorative component 21, simulating the effect of the heart ornament jumping.
