[0042] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. Now, with reference to the accompanying drawings, the preferred embodiments of the present utility model will be described in detail.

[0043] An embodiment of the present utility model provides a cleaning pen 1000, which is mainly used for cleaning electronic products. As Figures 1 - 6As shown, the cleaning pen 1000 includes a tube body 10, a cleaning member 20, and a pushing member 30. The tube body 10 includes a first end portion 11 at one end in its length direction. A guiding groove 12 communicating with the inside of the tube body 10 is provided through the tube body 10, and the guiding groove 12 extends in the length direction. A protruding portion 13 is provided on the guiding groove 12; the cleaning member 20 includes a first cleaning portion 24. The cleaning member 20 is movably connected to the inside of the tube body 10 in the length direction so that the first cleaning portion 24 extends out of or retracts into the first end portion 11; the pushing member 30 is installed on the cleaning member 20 and passes through the guiding groove 12. A groove 31 adapted to the protruding portion 13 is provided on the pushing member 30; wherein, when the pushing member 30 moves relative to the guiding groove 12, the groove 31 can cooperate with the protruding portion 13 to lock the extending position of the first cleaning portion 24. This application can solve the problem of cumbersome operation of the cleaning pen 1000 in the prior art. It simplifies the operation steps, is more convenient to use, and provides a better user experience.

[0044] Specifically, in the first aspect, during the operation, by pushing the pushing member 30, the protruding portion 13 is engaged with the groove 31, thereby locking the position of the first cleaning portion 24 to ensure its stability and reliability during use. When storing, pushing the pushing member 30 in the reverse direction can disengage the protruding portion 13 from the groove 31, unlocking the first cleaning portion 24 and allowing it to retract into the tube body 10. Compared with the prior art in which the cleaning pen 1000 is unlocked by first pressing and then pushing, the cleaning pen 1000 of this application only needs to push and pull back and forth to complete locking and unlocking. The operation is simpler and more direct. This one-step operation method not only simplifies the operation process but also improves the user experience, making the use of the cleaning pen 1000 more efficient and fast. In the second aspect, since the first cleaning portion 24 can retract into the tube body 10, the cleaning pen 1000 has a more compact structure, is more convenient to carry and store. And when the first cleaning portion 24 retracts into the tube body 10, the tube body 10 can also serve as a protective layer to prevent the first cleaning portion 24 from rubbing or colliding with other objects, improving the durability of the cleaning pen 1000.

[0045] In this application, the tube body 10 can be cylindrical, square, or other special shapes, which are not limited herein;

[0046] There are many ways to arrange the first cleaning portion 24 of the cleaning member 20. It can be arbitrarily adjusted for electronic products to be cleaned, such as keyboards, headphones, mobile phones, etc. Exemplarily, it can be a flocked sponge or a brush head. Of course, it can also be a metal pen tip 2411. Another example is that it can be a combination of a flocked sponge, a brush head, and a metal pen tip 2411, so as to effectively clean different types of electronic products or different parts of the same type of electronic product, improve the cleaning power of the cleaning pen 1000, and achieve multi-functional cleaning. Refer to Figure 3, specifically, in this embodiment, the first cleaning part 24 includes a base body 241 and a cover body 242. A metal nib 2411 is provided on the base body 241, and flocked sponge is provided outside the cover body 242. The cover body 242 is covered at the position of the metal nib 2411, so as to realize multi-functional cleaning.

[0047] Preferably, in order to improve the protection of the flocked sponge, in this application, a protective cover is further provided on the cover body 242. With such a setting, it can effectively prevent the flocked sponge from being exposed to the outside for a long time, reduce the intrusion of dust, and thus maintain its cleaning performance.

[0048] In one embodiment, the cleaning member 20 includes an intermediate part 26 connected to the first cleaning part 24. The intermediate part 26 is used to connect the pushing member 30. In this application, the intermediate part 26 is fixedly connected to the first cleaning part 24; optionally, the first cleaning part 24 and the intermediate part 26 can also be detachably connected, so that by setting a variety of different types of combinations of the first cleaning part 24 and the intermediate part 26, the applicable range of the cleaning pen 1000 can be improved, and the user can replace the first cleaning part 24 by himself according to needs during use.

[0049] In one embodiment, two protruding parts 13 can be provided. The two protruding parts 13 are arranged in sequence in the length direction. The protruding part 13 close to the first end 11 is used to lock the position of the first cleaning part 24 when it extends out, ensuring that the first cleaning part 24 is firmly fixed during use and will not move accidentally. The other protruding part 13 away from the first end 11 is used to lock the position of the first cleaning part 24 when it retracts, so as to prevent the first cleaning part 24 from extending out of the tube body 10 during storage, and improve the reliability of the cleaning pen 1000.

[0050] Preferably, the protruding part 13 can be made of an elastic material. The elastic protruding part 13 has deformation recovery, reduces the resistance of the pushing member 30, improves the smoothness of operation, and can achieve a closer fit with the groove 31.

[0051] Refer to Figure 5 And Figure 6, in one embodiment, the guide groove 12 includes a first side groove wall 121 and a second side groove wall 122 that are oppositely arranged in its width direction; the protruding part 13 is two protrusions 131, and the two protrusions 131 are respectively arranged on the first side groove wall 121 and the second side groove wall 122, and the two protrusions 131 are arranged in a staggered manner in the length direction. There are two grooves 31, and the two grooves 31 are respectively arranged in alignment with the corresponding protrusions 131. With such an arrangement, the two protrusions 131 cooperate with the two grooves 31, and the force on the pusher 30 is more uniform when it is locked, improving the locking stability. Moreover, since the two protrusions 131 are arranged in a staggered manner in the length direction, during the locking process of the first cleaning part 24, the pusher 30 will first contact one of the protrusions 131, and then complete the cooperation with the two protrusions 131 at the same time. Compared with the embodiment in which the two protrusions 131 are arranged opposite to each other, the pusher 30 will be stressed in stages during the locking process, reducing the resistance during the overall locking process and making the operation smoother.

[0052] In addition, in order to further improve the smoothness of locking during the operation. In the first embodiment, a first convex block 321 is provided on the side of the pusher 30 facing the first side groove wall 121, and one of the grooves 31 is arranged on the first convex block 321. The first convex block 321 is provided with a first guiding surface 3211 in the length direction, and the first guiding surface 3211 is used to abut against the protrusion 131 of the first side groove wall 121; in the second embodiment, a second convex block 322 is provided on the side of the pusher 30 facing the second side groove wall 122, and the other groove 31 is arranged on the second convex block 322. The second convex block 322 is provided with a second guiding surface 3221 in the length direction, and the second guiding surface 3221 is used to abut against the protrusion 131 of the second side groove wall 122. In the third embodiment, it is a combination of the first embodiment and the second embodiment.

[0053] Specifically, the pusher 30 includes a connecting part 32, and the connecting part 32 passes through the guide groove 12. The length of the connecting part 32 in the width direction is smaller than the width of the guide groove 12. The connecting part 32 includes a main body 323 and the first convex block 321 and the second convex block 322 located on both sides thereof. Both the first guiding surface 3211 and the second guiding surface 3221 are arranged at an angle with the length direction, and they are arranged in opposite directions in the length direction. Thus, during the process of pushing the pusher 30 back and forth, the first guiding surface 3211 or the second guiding surface 3221 can guide the corresponding protrusion 131 to be inserted into the corresponding groove 31 more smoothly, reducing the friction and resistance during the locking process, making the locking smoother and improving the locking stability.

[0054] Furthermore, the protrusion 131 has an arc surface 1311, and the shape of the groove 31 is adapted to the protrusion 131. In this way, the friction and resistance during the locking process are further reduced, making the operation smoother and improving the locking stability.

[0055] Preferably, the first bump 321 and / or the second bump 322 can be made of an elastic material to further improve the smoothness of operation and achieve a closer fit.

[0056] Referring to Figures 7 - 10 , in one embodiment, the pusher 30 includes a fixing portion 33 and a pressing portion 34. The pressing portion 34 is located outside the tube body 10, and the fixing portion 33 is located inside the tube body 10 and connected to the cleaning member 20. The fixing portion 33 includes two symmetrically arranged hooks 331, and the cleaning member 20 is provided with two blocks 21 adapted to the two hooks 331. With such an arrangement, the two hooks 331 are hooked to the blocks 21, and the pusher 30 can be connected to the cleaning member 20. The structural design is simple and the connection is reliable, not easy to loosen or fall off, which is beneficial to improving the stability and reliability of the operation of the cleaning pen 1000.

[0057] Specifically, the connecting portion 32 is located between the fixing portion 33 and the pressing portion 34, and the two hooks 331 are symmetrically and spaced apart in the length direction on the side of the connecting portion 32 facing away from the pressing portion 34.

[0058] More specifically, the hook 331 includes a hooking portion 3311 and a rod portion 3312. One end of the rod portion 3312 is connected to the connecting portion 32, and the hooking portion 3311 is provided on one side of the other end of the rod portion 3312 in the length direction.

[0059] Referring to Figures 7 - 10 , in one embodiment, the cleaning member 20 is provided with a receiving groove 22 on the side facing the guide groove 12, and the blocks 21 are provided on the groove wall of the receiving groove 22. The hooks 331 are inserted into the receiving groove 22 and hooked to the blocks 21. In this way, the groove wall of the receiving groove 22 can limit the movement of the hooks 331, further improving the connection stability. Moreover, the hooks 331 are inserted into the receiving groove 22, which can reduce the occupied space and the overall size of the cleaning pen 1000. Specifically, two receiving grooves 22 are provided, and the two blocks 21 are oppositely arranged in the two receiving grooves 22. Optionally, the block 21 is arranged close to the groove opening of the receiving groove 22 for faster cooperation between the two. Optionally, the receiving groove 22 penetrates through the cleaning member 20, so that the hooks 331 can be disengaged from the blocks 21 through the groove bottom to achieve a detachable connection.

[0060] Furthermore, the receiving groove 22 is adapted to the hook 331, that is, after the hook 331 is inserted into the receiving groove 22 for connection, there is a certain installation gap between the two, so that the hook 331 is easier to insert and position during connection, improving the installation efficiency and convenience, and at the same time avoiding the problem of poor unlocking and locking adaptation between the pusher 30 and the tube body 10 due to machining errors of parts.

[0061] In one embodiment, the engaging portion 3311 includes an end face facing the locking block 21 and a side face connected to the end face. A chamfer is provided at the connection between the end face and the side face. The chamfer is configured to abut against the locking block 21 when the snap hook 331 is inserted into the receiving groove 22, so as to cause the rod portion 3312 to deform, thereby more quickly inserting into the receiving groove 22 and engaging the engaging portion 3311 with the locking block 21.

[0062] Referring to Figure 10 With Figure 11 , in one embodiment, the cleaning pen 1000 further includes a damping assembly 40.
