[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Example: See Figures 1 to 14 A nail polish machine with replaceable batteries includes a body 1, a control panel 2 and a polishing pen 3. The control panel 2 is arranged on the body 1. The polishing pen 3 is electrically connected to the control panel 2 through a cable to provide control signals and driving power for the polishing pen 3. The head of the polishing pen 3 is equipped with a detachable grinding head for polishing nails.

[0041] This embodiment also includes: a mounting cavity 4, a battery pack 5, and an ejection mechanism 6. The mounting cavity 4 is located on the back of the housing 1 and is used to mount the battery pack 5. The battery pack 5 is removably connected to the mounting cavity 4 and electrically connected to the control panel 2, providing power to the control panel 2. The ejection mechanism 6 is provided on the housing 1 and is used to eject the battery pack 5 from the mounting cavity 4, facilitating removal and replacement.

[0042] The following is an introduction to the machine body 1:

[0043] The body 1 includes a bottom cover 101 , an outer frame 102 , a fixing bracket 103 and a top cover 104 .

[0044] The bottom cover 101 is detachably connected to the back of the outer frame 102. Normally, the bottom cover 101 shields the mounting cavity 4, forming a complete device and preventing the battery pack 5 from being exposed. When the battery pack 5 needs to be replaced, the bottom cover 101 must be removed first, and then the battery pack 5 can be taken out. In this embodiment, a plurality of iron sheets 7 are fixedly connected to the side of the bottom cover 101 near the outer frame 102, and magnets 8 corresponding to each iron sheet 7 are fixedly connected to the fixing bracket 103. The bottom cover 101 is detachably connected to the outer frame 102 through the cooperation of the iron sheets 7 and the magnets 8. Normally, the bottom cover 101 is fixed to the back of the outer frame 102 by magnetic force. When the battery needs to be replaced, the bottom cover 101 can be removed manually, or when the ejection mechanism 6 ejects the battery pack 5, the ejection force can be used to overcome the magnetic attraction, thereby lifting the bottom cover 101 and easily removing it.

[0045] In addition, the fixing bracket 103 is detachably connected to the outer frame 102. The cover 104 is located on the front of the outer frame 102 and is fixedly connected to the fixing bracket 103 via screws. The control panel 2, the mounting cavity 4, and the ejection mechanism 6 are respectively disposed on the fixing bracket 103. In this embodiment, a plurality of pressing blocks 9 are fixedly connected to both sides of the fixing bracket 103. A limiting groove 10 corresponding to each pressing block 9 is provided on the inner side of the outer frame 102. The fixing bracket 103 is detachably connected to the outer frame 102 through the cooperation between the pressing blocks 9 and the limiting grooves 10. When the outer frame 102 is placed on the outside of the fixing bracket 103, the pressing blocks 9 are snapped into the limiting grooves 10. The fixing bracket 103 then secures the cover 104 and the control panel 2 together via screws. This allows the outer frame 102, the fixing bracket 103, the cover 104, and the control panel 2 to be fixed and limited.

[0046] The ejection mechanism 6 is introduced as follows:

[0047] The ejection mechanism 6 includes a pressure plate 601 fixed to the bottom of the fixed bracket 103. A rotating shaft 602 is fixedly connected to the top of the pressure plate 601. A push rod 603 is rotatably connected to the rotating shaft 602. The pressure plate 601 is provided with an ejection switch 604 for rotating the push rod 603 along the rotating shaft 602. The lower end of the battery pack 5 is fixedly connected to an ejection boss 11 that adapts to the push rod 603. When the push rod 603 rotates along the rotating shaft 602, the push rod 603 and the ejection boss 11 cooperate to eject the battery pack 5 from the installation cavity 4.

[0048] It should be noted that the ejection switch 604 includes a slot 6041 defined on the pressure plate 601, within which a slide plate 6042 slides. A reset spring 6043 is secured to the pressure plate 601 for resetting the slide plate 6042. A beveled block 6044 is secured to the top of the slide plate 6042, and a lever 6045 is fixedly connected to the bottom of the slide plate 6042. A V-shaped rod 12, adapted to the beveled block 6044, is fixedly connected to the ejector rod 603. A horizontally disposed slot 13 is defined in the outer frame 102, through which the lever 6045 slides. When the lever 6045 is pushed to translate along the slot 13, the beveled block 6044 and the V-shaped rod 12 cooperate to drive the ejector rod 603 to rotate upward along the rotating shaft 602. Consequently, the ejector rod 603 and the ejection boss 11 cooperate to release the battery pack 5 from its original position.

[0049] After the battery pack 5 is removed, the reset spring 6043 causes the lever 6045, the inclined block 6044, and the slide 6042 to return to their initial positions, and the ejector pin 603 also rotates in the opposite direction around the rotating shaft 602 to its initial position. To enable the ejector pin 603 to rotate in the opposite direction to its initial position, a torsion spring can be provided at the junction of the ejector pin 603 and the rotating shaft 602. One torsion spring arm is connected to the ejector pin 603, and the other torsion spring arm is connected to the rotating shaft 602. The torsion force of the torsion spring enables the ejector pin 603 to rotate in the opposite direction to its initial position. Other methods can also be used to enable the ejector pin 603 to rotate in the opposite direction to its initial position.

[0050] The following is an introduction to the battery pack 5:

[0051] The battery pack 5 includes a housing 501 that is removably connected to the mounting cavity 4. A circuit board 502 and a battery body 503 are secured within the housing 501. The battery body 503 is electrically connected to the circuit board 502. A charging port 504 and a battery output port 505 are secured to the circuit board 502, located at the top of the housing 501. The charging port 504 allows for independent charging of the battery body 503. In this embodiment, the control panel 2 is also equipped with a charging port. When the device is idle, the battery pack 5 within the device 1 can be charged through this port. A spare battery pack 5 can also be charged through the charging port 504. A battery input port 14 is provided within the mounting cavity 4, cooperating with the battery output port 505. The battery input port 14 is electrically connected to the control panel 2. The battery output port 505 can be freely inserted into or removed from the battery input port 14, thereby providing power to the entire device.

[0052] It should be noted that the lower end of the housing 501 is provided with a plurality of slots 15, and a retaining spring clasp 16 corresponding to each slot 15 is fixed to the bottom of the mounting cavity 4. The housing 501 is removably connected to the mounting cavity 4 through the cooperation between the slots 15 and the retaining spring clasp 16. The retaining spring clasp 16 engages the slots 15 to secure the battery pack 5 in place. In this embodiment, the housing 501 comprises a removably connected upper cover and lower cover, facilitating the removal and installation of the circuit board 502 and the battery body 503.

[0053] Here’s how it works:

[0054] When the battery pack 5 needs to be removed, the lever 6045 is pushed to move horizontally, thereby driving the top rod 603 to rotate upward along the rotating shaft 602 through the cooperation of the inclined block 6044 and the V-shaped rod 12, and overcoming the suction force of the iron sheet 7 and the magnet 8, while overcoming the pressure of the limit spring buckle 16, so that the bottom cover 101 and the battery pack 5 are separated from their original positions, and then the bottom cover 101 and the battery pack 5 can be easily removed. After removing the battery pack 5, the lever 6045 returns to its original position under the action of the reset spring 6043. The top rod 603 also rotates in the opposite direction around the rotating shaft 602 to its original position. When a new battery pack 5 needs to be installed, just press the battery output interface 505 into the installation cavity 4 in the direction corresponding to the battery input interface 14, and make the limit spring buckle 16 snap into the card slot 15, then cover the bottom cover 101, and you can continue with the nail polishing work.
