[0002] In modern dental treatment, disposable dental handpieces are commonly used instruments, and their portability, ease of operation, and aesthetic appeal are crucial to dentists' work efficiency and patient experience. Currently, most disposable dental handpieces on the market use button batteries as their power source. However, these products have a significant design flaw: the button battery protrudes from the handle. This design causes several problems. First, because the battery protrudes from the handle, the overall size of the handle increases. This not only increases the space occupied by the dentist during operation but may also hinder hand movements, reducing flexibility and precision. Especially during delicate dental treatments, such as dental restorations and root canals, dentists need to concentrate highly and precisely control the movement of the dental handpiece; the increased handle size undoubtedly increases the difficulty of operation. Second, the protruding battery design also affects the overall shape and appearance of the handle. In the trend of modern medical equipment pursuing humanization and aesthetics, this design appears less refined and may even give patients an unprofessional impression. Utility Model Content

[0027] To reduce costs, disposable dental handpieces typically use button batteries (300) to power the illumination lamp (120). A common method for installing the button battery (300) involves a slightly larger circular opening than the battery itself. Since the handle of a disposable dental handpiece is small and cannot accommodate a circular opening, conventional disposable dental handpieces have a protruding battery compartment (110) with a circular opening for battery installation. However, this protrusion affects the dentist's operation. The battery protrudes beyond the handle (100), increasing the overall size of the handle. This not only increases the space occupied by the dentist during operation but may also hinder hand movements, reducing dexterity and precision. Therefore, referring to… Figures 1 to 3 This utility model provides a button battery mounting structure for a disposable dental handpiece, and provides the following embodiments:

[0028] The button battery mounting structure includes a handle 100 and a head 200. The head 200 is fitted with a needle 210. The handle 100 has an operating end and a connecting end at its two ends, respectively. The head 200 is located at the operating end, and a light 120 protrudes from the operating end, positioned close to the head 200. The light 120 is positioned opposite the cutting part of the needle 210 to illuminate the cutting area, facilitating the doctor's operation. In other embodiments, the light 120 may be embedded within the handle 100, reducing visual interference and further enhancing the doctor's operation.

[0029] The handle 100 is embedded with a battery compartment 110, which has a cover 111 and an opening 112. The conductive sheet of the battery compartment 110 is electrically connected to the lighting lamp 120, directly guiding electricity to the lighting lamp 120 and reducing light efficiency loss. Some dental handpieces place the lighting lamp 120 at the quick connector and then guide the light to the lighting location through an optical fiber, resulting in greater light efficiency loss. This application improves lighting efficiency by electrically connecting the button battery 300 to the lighting lamp 120 with a wire.

[0030] In this application, the opening 112 is elongated, allowing the battery compartment 110 to be embedded within the handle 100, eliminating the need for the battery compartment 110 to protrude from the outer wall of the handle 100. The opening 112 is located on the outer peripheral wall of the handle 100, and the outer surface of the cover 111 smoothly transitions to the outer peripheral wall of the handle 100 for easy gripping. The battery compartment 110 houses a button battery 300, facilitating its insertion into the handle.

[0031] The button battery 300 meets the manufacturing cost requirements of disposable dental handpieces. Compared to traditional button battery installation methods, the button battery 300 of this application, being embedded in the handle 100, does not affect the original volume of the handle 100, which is beneficial for the doctor's operation. Secondly, this structure does not affect the overall shape and appearance of the handle 100, which helps to improve aesthetics.

[0032] During dental procedures, dental handpieces, as critical instruments, frequently come into contact with various liquid media and may require cleaning as needed. To effectively prevent liquid from seeping into the battery compartment 110 of the dental handpiece during cleaning, thus avoiding damage such as corrosion or short circuits to the button battery 300 inside, and ensuring the performance and lifespan of the dental handpiece, a sealing structure is installed at the contact point between the cover 111 and the opening 112 of the battery compartment 110. Specifically, a sealing ring is used to achieve a reliable seal. The sealing ring is typically made of elastic rubber. This material not only has good elasticity, allowing it to fit tightly against the edge of the opening 112 when the cover 111 is closed, filling the tiny gaps between them and forming a waterproof barrier, but also has chemical corrosion resistance, resisting the erosion of various cleaning agents and disinfectants that may be used during cleaning, ensuring stable and reliable sealing performance over long-term use.

[0033] By setting up such an elastic rubber sealing ring, not only is it effective to prevent cleaning liquid from entering the battery compartment 110 and protect the safety of the dental handpiece, but it also greatly reduces the risk of equipment failure caused by liquid seepage, reduces maintenance costs and downtime, and improves the efficiency and reliability of dental treatment.

[0034] To minimize the concealment of the button battery 300 within the handle 100, the extending plane of the button battery 300 passes through the axis of the handle 100, meaning the extending plane of the battery compartment 110 also passes through the axis of the handle 100. The button battery 300 is located at the position of the handle 100's maximum cross-section, maximizing the size of the button battery 300 that can be installed. Simultaneously, the installation of the button battery 300 does not affect the installation of other wiring within the handle 100, such as the air intake pipe, air return pipe, and atomizing pipe. Of course, if the radial width of the handle 100 is sufficient, the extending plane of the button battery 300 can also be positioned in other locations.

[0035] Furthermore, the battery compartment 110 is provided with a first abutting surface and a second abutting surface that respectively contact the two end faces of the button battery 300. The first abutting surface is provided with an electrode plate, and the second abutting surface is provided with a fixing spring. When the button battery 300 is inserted into the battery compartment 110, the two end faces of the button battery 300 abut against the first abutting surface and the second abutting surface respectively. At the same time, the fixing spring securely fixes the button battery 300, improving conductivity and reducing the occurrence of poor contact.

[0036] Furthermore, the cover 111 is snapped into the battery compartment 110. The cover 111 is provided with a buckle that snaps into the battery compartment 110. The handle 100 is provided with a clearance groove. The clearance groove is located on the outer periphery of the cover 111. When removing the cover 111, the tool is inserted into the clearance groove and force is applied to the cover 111 to remove it.

[0037] To ensure the cover 111 is securely mounted on the battery compartment 110 while allowing for easy removal, the cover 111 is connected to the battery compartment 110 via a snap-fit ​​mechanism. Specifically, the cover 111 has a snap-fit ​​structure specifically adapted to the battery compartment 110. Meanwhile, considering that battery replacement and maintenance of the battery compartment 110 may be required in actual use, easy removal of the cover 111 from the battery compartment 110 is necessary. Therefore, a clearance groove is provided on the handle 100. This clearance groove is located on the outer periphery of the cover 111, and its width and depth are rationally designed to ensure that it does not affect the overall structural strength and grip comfort of the handle 100, while providing sufficient operating space for disassembly tools.

[0038] When it is necessary to remove the cover 111, the operator only needs to insert a suitable tool, such as a small screwdriver or pry bar, into the clearance groove, and then apply appropriate external force to the cover 111. Utilizing the elastic deformation characteristics of the clips, the locking structure between the cover 111 and the battery compartment 110 can be easily disengaged, thus enabling the cover 111 to be removed smoothly. This design not only greatly simplifies the disassembly process of the cover 111 and improves the convenience of operation, but also avoids damage to the cover 111 or battery compartment 110 caused by forced disassembly, extending the service life of the equipment.

[0039] Furthermore, the inner wall of the battery compartment 110 is provided with an arc-shaped groove 113. The shape of the arc-shaped groove 113 matches the circumferential side surface of the button battery 300, which is used to snap and fix the button battery 300, so that the button battery 300 can be stably snapped in and prevent longitudinal displacement or shaking. The end of the battery compartment 110 near the compartment opening 112 is provided with a reserved area 114. When the compartment cover 111 is closed, the inner side of the compartment cover 111 abuts against the circumferential surface of the button battery 300. When the compartment cover 111 is closed, the inner side of the compartment cover 111 abuts against the circumferential surface of the battery to further fix the button battery 300, improve the conductivity, and reduce the occurrence of poor contact.

[0040] Meanwhile, the reserved area 114 is located between the circumferential side of the button battery 300 and the inner wall of the battery compartment 110. When removing the button battery 300, a finger or tool can be inserted into the reserved area 114 for easy removal. The user pushes the button battery 300 into the battery compartment 110 along the arc-shaped groove 113, and the battery automatically snaps into the correct position.

[0041] Overall, the button battery 300 mounting structure not only does not increase the original size of the handle 100, making it easier for doctors to operate, but also has the characteristics of firmly and reliably fixing the button battery 300, and the operation of removing and installing the button battery 300 is very convenient.

[0042] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
