Abstract
Description
Technical Field
[0001] This utility model relates to the field of nail polishing technology, specifically a nail polishing machine with a display screen. Background Technology
[0002] There are many types of nail filers on the market, but they are all used in a similar way. When using a filer, select the file head you need, attach it to the main unit, and then slowly bring the rotating file head close to your fingernails or toenails. This way you can file the nails into the shape you want. It can also be used for polishing and removing cuticles, so it is very convenient to use.
[0003] However, existing nail file equipment requires certain operating skills from users, and beginners are not very adaptable, which can easily lead to uneven filing, inconsistent thickness, or even nail burn-through. Therefore, we propose a nail file machine with a display screen. Utility Model Content

A controller, a motor, and a second data cable are fixedly mounted inside the handle. The motor and the second data cable are electrically connected to the controller. The controller is electrically connected to the main unit through the first data cable. A mounting head is fixedly mounted at the output end of the motor, and a polishing head is mounted on the outside of the mounting head. The camera is fixedly mounted at the end of the second data cable away from the controller. A display panel electrically connected to the main unit is fixedly mounted on the outside of the main unit. The sleeve engages with the external thread on the outside of the handle through an internal thread. The outside of the sleeve has through holes corresponding to the polishing head and the camera. The auxiliary components are located inside the sleeve for protecting the camera.

[0022] Example
[0023] Please see Figures 1-4 The illustration shows a nail file with a display screen, comprising a main unit 1, a camera 9 electrically connected to the main unit 1, a sleeve 11, and an auxiliary component 13. A first data cable 2 is fixedly mounted on the outside of the main unit 1, and a handle 3 is fixedly mounted at the end of the first data cable 2. A controller 4, a motor 5, and a second data cable 6 are fixedly mounted inside the handle 3. The motor 5 and the second data cable 6 are electrically connected to the controller 4 (the controller 4 can adopt the control board structure in the patent with publication number CN220607655U). The controller 4 is electrically connected to the main unit 1 via the first data cable 2. The output end of the motor 5 is fixed... The device is equipped with an installation head 7, and a grinding head 8 is installed on the outside of the installation head 7. A camera 9 is fixedly installed at the end of the second data cable 6 away from the controller 4. A display panel 10 electrically connected to the host 1 is fixedly installed on the outside of the host 1. A sleeve 11 is engaged with an external thread on the outside of the handle 3 through an internal thread. The sleeve 11 has through holes 12 on the outside corresponding to the grinding head 8 and the camera 9. When the grinding head 8 is grinding the nail, the camera 9 records the situation of the grinding area in real time and transmits the information to the display panel 10 for the user to view, so that the user can control the grinding force.
[0024] The auxiliary component 13 is located inside the sleeve 11 to protect the camera 9 and prevent external debris from soiling the camera 9 and making it difficult to clean.
[0025] The following describes some embodiments of this application in detail with reference to the accompanying drawings:
[0026] Please see Figures 1-4 By setting a camera 9 at the grinding head 8, the camera 9 can be used to observe the nail grinding process and transmit the status of the grinding area to the display panel 10 in real time, thus assisting the user in controlling the grinding head 8 to grind the nails.
[0027] The auxiliary component 13 includes an auxiliary cylinder 14, which is slidably disposed inside the sleeve 11. The auxiliary cylinder 14 is fixedly provided with uniformly distributed protective lenses 15 on the side near the through hole 12. By setting a rotatable auxiliary cylinder 14 inside the sleeve 11 and setting multiple protective lenses 15 on the auxiliary cylinder 14, the protective lenses 15 are used to protect the camera 9 inside the through hole 12, preventing external debris from contaminating the camera 9. At the same time, when one protective lens 15 is dirty, it is only necessary to rotate the auxiliary cylinder 14 to rotate the other clean protective lenses 15 on the auxiliary cylinder 14 to the camera 9 to protect the camera 9.
[0028] Meanwhile, the handle 3 has a ring-shaped slot 16 on its outer side. The slot 16 is located inside the sleeve 11. The bottom of the auxiliary cylinder 14 has a plug that mates with the slot 16. The auxiliary cylinder 14 is pressed into the ring groove by the sleeve 11, which can prevent the auxiliary cylinder 14 from shaking.
[0029] At the same time, a limiting sleeve 17 is fixedly provided on the inner side of the protective goggles 15. The camera 9 cooperates with the inner side of the limiting sleeve 17. The limiting sleeve 17 can cover the protective goggles 15 on the camera 9, which can prevent the camera 9 and the protective goggles 15 from being misaligned and affecting the normal recording of the camera 9.
[0030] In addition, a retaining ring 18 is provided in the through hole 12 located at the grinding head 8. One end of the retaining ring 18 is fixed to the sleeve 11, and the other end of the retaining ring 18 is sealed and fitted to the handle 3, which can minimize the amount of dust entering the camera 9.
[0031] The principle behind this technical solution for facilitating personnel control of the nail-grinding head 8 is as follows:
[0032] First, align the limiting sleeve 17 with the camera 9, then insert the auxiliary tube 14 into the slot 16 through the insert block, and then screw the sleeve 11 onto the outside of the handle 3 through the thread. Use the sleeve 11 to press the auxiliary tube 14 against the outside of the handle 3, and the protective lens 15 can be attached to the camera 9 to protect the camera 9.
[0033] Afterwards, the controller 4 inside the handle 3 controls the operation of the motor 5 and the camera 9. The motor 5 drives the grinding head 8 to rotate through the mounting head 7. The person can hold the handle 3 to perform the grinding operation. During the grinding process, the camera 9 transmits the situation of the grinding area to the display panel 10 in real time to help the person control the grinding force and avoid uneven grinding or inconsistent thickness.
[0034] In this technical solution, when too much dust adheres to the protective goggle 15, the sleeve 11 and the auxiliary sleeve 14 are removed, the auxiliary sleeve 14 is rotated, the clean protective goggle 15 on the auxiliary sleeve 14 is attached to the camera 9, and then the sleeve 11 is reinstalled.
[0035] In this technical solution, a rubber pad is fixedly provided on the side of the retaining ring 18 that contacts the handle 3, which can further improve the sealing between the retaining ring 18 and the handle 3.
[0036] In this technical solution, such as Figure 3 As shown, the sleeve 11 has an anti-slip groove on the outside, which makes it convenient for personnel to rotate the sleeve 11.
[0037] In this technical solution, such as Figure 2 As shown, a limiting ring 19 is fixed on the outside of the handle 3 to limit the travel range of the sleeve 11, so as to prevent the sleeve 11 from rotating excessively. After the control sleeve 11 and the handle 3 are installed together, the camera 9 is exactly in the through hole 12.
[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
