Description

Technical Field

[0001] This utility model relates to the field of dental medical device technology, specifically to a magnetic quick-release structure and a dental light curing machine including the structure. Background Technology

[0002] Dental light curing machines are core equipment in dental clinics for curing composite resins and other materials. They use blue light of a specific wavelength to excite photoinitiators, which promotes the polymerization of resin monomers, enabling dental restoration operations such as caries repair and orthodontic bracket bonding. They are characterized by quick operation, high precision, and good biocompatibility, and are a basic instrument in modern oral diagnosis and treatment.

[0003] Existing direct-connect magnetic structures in dental light-curing machines mainly consist of a ring-shaped permanent magnet at the main unit interface and a magnetic metal sheet or another set of ring-shaped permanent magnets at the component end. They rely on magnetic force for tool-free assembly and disassembly, simplifying the operation. However, this structure has significant drawbacks: First, the magnetic force configuration is limited; axial linear disassembly results in either excessively strong magnetic force making disassembly difficult or insufficient force leading to unreliable adhesion. Second, it lacks an angle locking mechanism; components are prone to detachment when the device is tilted more than 30° or subjected to lateral impact. Third, the blind operation experience is poor; users cannot judge whether the adhesion is in place by sight or touch, easily leading to incomplete connections. Utility Model Content

[0004] The purpose of this invention is to solve the problems of contradictory magnetic force configuration, high risk of falling off, and poor blind operation effect of existing magnetic suction structures, and to provide a magnetic quick-release structure and dental light curing machine that achieves a balance between reliable adsorption and convenient disassembly.

[0005] The technical solution to achieve the purpose of this utility model is: A magnetic quick-release structure is characterized by comprising a main unit component and a detachable battery component. The main unit component is provided with a main unit magnetic chuck, and the battery component is provided with a battery magnetic chuck. Both the main unit magnetic chuck and the battery magnetic chuck are multi-pole magnetic structures, which are formed by alternating arrangements of several sets of N-pole and S-pole or same-pole magnets and magnetic metals. When the two sets of magnetic chucks are close together, they attract each other to achieve positioning. After the main unit component and the battery component are rotated relative to each other to a critical angle, the repulsive force generated by the two sets of magnetic chucks is greater than the attractive force, achieving automatic pop-out separation.

[0006] The multi-pole magnetic attraction structure is formed by at least two sets of alternating N poles and S poles or by at least two sets of alternating magnets and magnetic metals of the same pole.

[0007] The multi-pole magnetic attraction structure consists of two sets of arc-shaped permanent magnets with alternating N and S poles.

[0008] The main unit component also includes a handle housing, a lower circuit fixing component, a lower power supply circuit board, a spring pin fixing component, a metal spring pin, and a tightening collar; the lower power supply circuit board is installed inside the handle housing through the lower circuit fixing component, the main unit magnetic component is fixed on the spring pin fixing component, the metal spring pin is electrically connected to the lower power supply circuit board and passes through the spring pin fixing component; the tightening collar is sleeved on the outside of the spring pin fixing component for limiting and fixing.

[0009] The battery assembly also includes a battery sleeve, a battery, and a sleeve cover; the battery is housed inside the battery sleeve, the sleeve cover seals one end of the battery sleeve, and the battery end magnetic attachment is fixed to the other end of the battery sleeve.

[0010] The battery assembly is connected to the main unit assembly via an embedded method, with the battery sleeve extending into the handle housing.

[0011] The metal spring pin is configured to correspond to the battery, and is used to realize the electrical connection between the host-side component and the battery component.

[0012] A dental light-curing machine includes the aforementioned magnetic quick-release structure, which enables quick assembly and disassembly of the battery assembly and stable electrical connection with the main unit.

[0013] The magnetic quick-release structure and dental light curing machine provided by this utility model have the following advantages compared with the prior art: 1. More rational magnetic force configuration: The multi-pole alternating arrangement of magnets increases the upper limit of magnetic force, which not only ensures the reliability of adsorption, but also enables convenient disassembly through rotation-triggered repulsion, thus solving the problem of magnetic force contradiction in traditional structures.

[0014] 2. Strong connection stability: The design of the battery assembly embedded in the main unit handle, combined with the closed-loop magnetic field, significantly reduces the risk of detachment during lateral collisions or tilting.

[0015] 3. High ease of operation: It supports blind rotation and disassembly without tools, and the change in magnetic resistance during rotation provides clear visual and tactile feedback, avoiding loose connections. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this is not intended to limit the present invention. Example

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the magnetic quick-release structure includes a main unit assembly and a battery assembly. In the main unit assembly, the lower circuit fixing member 5 is fixed inside the handle housing 1, the lower power supply circuit board 6 is mounted on the lower circuit fixing member 5, the spring pin fixing member 10 is limited and fixed by the tightening collar 9, the metal spring pin 11 passes through the spring pin fixing member 10 and is electrically connected to the lower power supply circuit board 6, and the main unit magnet 7 is fixed to the end of the spring pin fixing member 10 facing the battery assembly.

[0019] In the battery assembly, battery 3 is installed inside battery sleeve 2, and sleeve rear cover 4 seals the tail of battery sleeve 2. Battery end magnet 8 is fixed to the head of battery sleeve 2, corresponding to main unit end magnet 7. Both main unit end magnet 7 and battery end magnet 8 are four pairs of quarter-circle permanent magnets, with N / S poles alternately arranged to form a closed loop magnetic field.

[0020] During installation, align the head of the battery sleeve 2 with the port of the handle housing 1. The magnet 7 on the main unit side and the magnet 8 on the battery side will automatically attract each other due to the attraction of opposite magnetic poles, completing the initial positioning. At this time, the metal spring pin 11 is electrically connected to the battery 3 to provide power. During disassembly, rotate the battery assembly with one hand. The relative positions of the two sets of magnets will gradually change. The like magnetic poles will overlap and generate a repulsive force. When rotated to a critical angle, the repulsive force is greater than the attractive force, and the battery assembly will automatically spring open, completing the disassembly.
