[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a magnetic quick-change curling iron mold device, including a handle 1, one end of which is magnetically connected to a connecting seat 2. A magnetic block 11 is fixedly installed on the outer side of the upper middle part of the handle 1. Pressing grooves 13 are opened at both ends of the upper middle part of the handle 1. Moving grooves 15 are opened on both sides of the magnetic block 11. Limiting grooves 14 are opened on both sides of the middle part of the pressing groove 13. A pressing block 16 is slidably engaged in the middle of the pressing groove 13. Limiting blocks 17 are fixedly installed on both sides of the pressing block 16. A spring piece 18 is fixedly installed in the middle of the pressing block 16. One end of the spring piece 18 is fixedly connected to the inner wall of the pressing groove 13. The upper end of the pressing block 16 is... An L-shaped card plate 19 is fixedly installed. A magnetic block 21 is fixedly installed on the outer side of the lower middle part of the connecting seat 2. L-shaped slots 23 are opened on both sides of the magnetic block 21. A cross slot 12 is opened in the middle of the upper end of the handle 1. A cross rod 22 is fixedly installed in the middle of the lower end of the connecting seat 2. The cross rod 22 and the cross slot 12 are inserted together. The limiting block 17 is slidably engaged in the middle of the limiting groove 14. The L-shaped card plate 19 is slidably engaged in the middle of the moving groove 15. Magnetic block 11 and magnetic block 21 are magnetically connected. The corner of the L-shaped card plate 19 is engaged with the corner of the L-shaped slot 23. The diameter of the L-shaped slot 23 and the moving groove 15 are both larger than the diameter of the L-shaped card plate 19.
[0024] In this embodiment, the magnetic connection between magnetic block 11 and magnetic block 21 provides basic attraction force. The insertion structure of the cross-shaped insert 22 and the cross-shaped slot 12 achieves precise positioning and auxiliary fixation, effectively preventing the mold from shifting during the connection process. Simultaneously, the L-shaped locking plate 19 and the L-shaped slot 23 engage to form a mechanical locking structure. When the L-shaped locking plate 19 slides into the corner of the L-shaped slot 23 and locks in place, the connection strength is further enhanced. This dual protection of magnetic attraction and mechanical locking ensures that even when curling hair... Even with frequent wrist movements and hair pulling on the mold during the process, the connecting seat 2 and handle 1 remain firmly connected, preventing the mold from loosening or falling off and causing burns. The press-to-unlock structure, consisting of the pressing block 16, the limiting block 17, and the spring piece 18, is very convenient to operate. When the mold needs to be replaced, simply press the pressing block 16, the spring piece 18 is compressed, and the L-shaped locking plate 19 exits from the L-shaped locking slot 23. Combined with the magnetic structure, the connecting seat 2 and handle 1 can be quickly separated. When installing a new mold, the cross-shaped insert 22 is aligned with the handle 1. When the cross-shaped slot 12 is inserted, the connecting seat 2 automatically approaches the handle 1 under the action of magnetic attraction. The L-shaped card plate 19 slides into the L-shaped slot 23 and locks in place. Without the need for complicated alignment and adjustment, quick and accurate shape change can be achieved, greatly improving the efficiency of use. After daily use, users can easily disassemble the connecting seat 2 to perform deep cleaning on the magnetic block 11, magnetic block 21, and other parts that easily attract hair and dust. This effectively prevents impurities from weakening the magnetic force, extends the service life of the device, and maintains the stability of the magnetic connection effect. The limiting groove 14 limits the limiting block 17, and the moving groove 15 guides the L-shaped card plate 19, ensuring the smoothness of the pressing operation and the stability of the structure, and preventing damage to the parts due to uneven force. At the same time, the design of the L-shaped slot 23 and the moving groove 15 having a larger diameter than the L-shaped card plate 19 not only provides space for the sliding of the L-shaped card plate 19, but also prevents it from accidentally coming out when not pressed. Through clever size design and structural cooperation, the durability of the entire device is improved.
[0025] Example 2: As Figure 1-5 As shown, a detachable curling iron 27 is fixedly installed on the upper end of the connecting base 2. Multiple heat dissipation holes 28 are evenly opened on the surface of the detachable curling iron 27. A hair comb 29 is fixedly installed on one side of the detachable curling iron 27. A heating rod 30 is fixedly installed in the middle of the upper end of the connecting base 2. The detachable curling iron 27 is located on the outside of the heating rod 30. A switch button 26 is provided in the middle of the lower end of the handle 1. Multiple indicator lights 24 are evenly arranged in the middle of one side of the handle 1. Control buttons 25 are provided at both ends of the middle of one side of the handle 1.
[0026] In this embodiment, the multiple heat dissipation holes 28 evenly distributed on the surface of the detachable curling iron 27 can accelerate the heat dissipation during the curling process and prevent the curling iron from becoming too hot in some areas. The hair comb 29 fixedly installed on one side of the detachable curling iron 27 can comb the hair before the curling operation, straighten the knotted and tangled hair strands, and make the hair wrap more smoothly around the curling iron, thereby creating a neater and more beautiful hairstyle. During the curling process, the hair comb 29 can also help adjust the position and angle of the hair, helping users to more easily create the ideal curl and style without the need for an extra comb, simplifying the operation process and improving the convenience of use. The heating rod 30 in the middle of the upper end of the connecting base 2 is located inside the detachable curling iron 27, which can quickly and evenly curl the hair. The curling iron is heated to ensure a uniform surface temperature, guaranteeing even heating of the hair during curling. This ensures consistent and long-lasting curls, preventing uneven curls in some areas and improving the overall curling effect and quality. The switch button 26 at the bottom of the handle 1 allows users to easily turn the curling iron on or off, providing simple and direct operation. Multiple indicator lights 24 clearly display the curling iron's working status, such as whether the power is on, whether heating is complete, and the temperature setting, allowing users to monitor the equipment's operation and make timely adjustments. The control buttons 25 on both sides can be used to adjust the heating temperature, select curling modes, and precisely control the curling process to meet diverse user needs.
[0027] like Figure 1-5As shown, when connecting the connector 2 to the handle 1, first insert the cross-shaped insert 22 at the lower end of the connector 2 into the cross-shaped slot 12 at the upper end of the handle 1. At this time, the first magnetic block 11 and the second magnetic block 21 approach each other and automatically attract each other under the action of magnetic force, so that the connector 2 and the handle 1 are initially connected. At the same time, the L-shaped slot 23 on the connector 2 corresponds to the L-shaped plate 19 on the handle 1. As the connector 2 moves closer to the handle 1, the L-shaped plate 19 slides into the L-shaped slot 23 along the moving groove 15 under the action of magnetic attraction and its own elasticity. When the corner of the L-shaped plate 19 engages with the corner of the L-shaped slot 23, a stable mechanical connection is formed, ensuring that the connector 2 and the handle 1 are tightly fixed, preventing loosening or falling off during use. The curling iron can be turned on or off by the switch button 26 at the lower middle of the handle 1. After being turned on, the temperature of the heating rod 30 can be adjusted or different curling modes can be selected using the control button 25 in the middle of one side of the handle 1. At this time, the indicator light 24 will display the working status of the curling iron, such as the current temperature setting and whether heating is complete, so that users can understand the operation of the device and perform corresponding operations. The heating rod 30 starts to work, and the heat generated is transferred to the detachable curling iron 27. Since the heating rod 30 is located inside the detachable curling iron 27, and the structural design of the detachable curling iron 27 allows the heat to be evenly distributed on its surface. Before curling, users can first use the hair comb 29 to comb their hair to make it smooth, and then wrap the hair around the detachable curling iron 27. During the curling process, the evenly spaced heat dissipation holes 28 on the surface of the detachable curling iron 27 can dissipate heat in a timely manner. This prevents the detachable curling iron 27 from overheating and damaging the hair, and also ensures safety during the curling process. When it is necessary to change to a curling iron mold of a different shape or size, press down the pressing block 16. The pressing block 16 slides in the pressing groove 13, and the limiting blocks 17 on both sides slide synchronously in the limiting groove 14, ensuring the stability of the moving trajectory of the pressing block 16. At the same time, the spring piece 18 is deformed by the pressure of the pressing block 16, and the L-shaped locking plate 19 moves with the pressing block 16 and exits from the L-shaped locking groove 23, releasing the mechanical locking. At this time, under the action of magnetic force and external force, the connecting seat 2 separates from the handle 1, and the current detachable curling iron 27 can be removed. Then, replace it with the new detachable curling iron 27 as needed, and repeat the connection and fixing steps to achieve quick shape change.
