Description

Technical Field

[0001] This utility model relates to the field of cleaning and disinfection machines, and in particular to a dental ultrasonic cleaning and disinfection machine. Background Technology

[0002] An ultrasonic cleaning and sterilization machine is a composite device integrating ultrasonic cleaning technology and sterilization functions. It is primarily used for deep cleaning of items while simultaneously killing bacteria, viruses, and other microorganisms. It uses the physical action of ultrasound to remove stains, combined with chemical or physical sterilization methods (such as high temperature, ultraviolet light, ozone, etc.) to achieve thorough sterilization. It is widely used in fields with high cleanliness and hygiene requirements, such as medical, laboratory, catering, jewelry, and electronics industries. The ultrasonic cleaning and sterilization machine has two main functions: "ultrasonic cleaning" and "sterilization." The ultrasonic cleaning principle involves an ultrasonic generator producing high-frequency electrical signals (typically 20-100kHz), which are converted into mechanical vibrations by a transducer and transmitted to the liquid (water or a specialized cleaning agent) in the cleaning tank. Under high-frequency vibration, the liquid molecules generate a "cavitation effect"—countless tiny bubbles are instantly generated and burst, releasing a powerful impact force (up to 1000 atmospheres), penetrating deep into the crevices and pores of the item's surface, removing stubborn stains such as grease, particles, and bloodstains, achieving highly efficient physical cleaning. The sterilization principle mainly utilizes ultraviolet light to destroy the DNA / RNA structure of microorganisms.

[0003] Dental supplies typically include toothbrushes, braces, tweezers, clamps, and scissors. These supplies usually require ultrasonic cleaning and sterilization before or after use. Currently, ultrasonic cleaners for dental supplies are typically box-shaped, consisting mainly of a base and a cover. The base contains a cleaning tank, a control panel, and an ultrasonic device, while the cover houses a UV lamp. This type of ultrasonic cleaner requires opening the cover to load and unload dental supplies each time, which is inconvenient. Furthermore, current ultrasonic cleaners have poor sealing and waterproofing, making them difficult to clean. Therefore, it is necessary to improve current ultrasonic cleaners. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main objective is to provide a dental ultrasonic cleaning and sterilization machine that can effectively solve the problems of inconvenience in use and poor waterproof performance of existing ultrasonic cleaning and sterilization machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dental ultrasonic cleaning and sterilizing machine includes a base, a cover, a control board, an ultrasonic device, and an ultraviolet lamp device. The base includes a housing and an inner liner. The inner liner is disposed within the housing and forms a first mounting cavity with the housing. The inner liner has a cleaning tank with an upward-facing opening for placing dental objects to be cleaned. The cover is closable and mounted on the base. When closed, the cover covers the opening of the cleaning tank. The cover has a second mounting cavity, and insertion holes for inserting dental objects are formed through the upper and lower surfaces of the cover. The insertion holes communicate with the cleaning tank, and a flexible light-shielding element that can open and close automatically is provided in the insertion holes. The control board and the ultrasonic device are both disposed in the first mounting cavity. The ultrasonic device is electrically connected to the control board and contacts the outer bottom of the inner liner. The ultraviolet lamp device is disposed in the second mounting cavity and is electrically connected to the control board. The ultraviolet light generated by the ultraviolet lamp device shines downward into the cleaning tank through the cover.

[0007] As a preferred embodiment, the flexible light-shielding element is a plastic sheet, and a gap is formed through the center of the upper and lower surfaces of the flexible light-shielding element, and the gap is in the shape of a cross.

[0008] As a preferred embodiment, there are at least two insertion holes, which are set separately, and each insertion hole is provided with a flexible light-shielding element that can be opened and closed automatically.

[0009] As a preferred embodiment, the housing includes a bottom housing and a main housing. The bottom end of the main housing is spliced ​​to the top end of the bottom housing, and a first sealing ring is sandwiched between the bottom end of the main housing and the top end of the bottom housing. The top periphery of the inner liner is sealed and fixed to the top periphery of the main housing. The inner liner, the main housing, and the bottom housing form the aforementioned first mounting cavity.

[0010] As a preferred embodiment, the inner liner is made of stainless steel and is fixedly connected to the main shell by multiple screws.

[0011] As a preferred embodiment, the cover includes a lower cover and an upper cover, which are spliced ​​together to form the aforementioned second mounting cavity. A second sealing ring is sandwiched between the upper cover and the lower cover. The insertion hole passes through the upper cover and the lower cover, and the periphery of the flexible light shield is clamped between the upper cover and the lower cover.

[0012] As a preferred embodiment, the lower cover has multiple light-transmitting holes that are connected to the second mounting cavity, and the ultraviolet light generated by the ultraviolet lamp device shines downward into the cleaning tank through the multiple light-transmitting holes.

[0013] As a preferred embodiment, the rear edge of the upper cover is hinged to the rear edge of the top of the housing.

[0014] As a preferred embodiment, the cleaning tank is provided with a removable basket.

[0015] As a preferred embodiment, the ultrasonic device includes an ultrasonic generator and an ultrasonic transducer. The ultrasonic generator is electrically connected to a control board, and the ultrasonic transducer is fixedly attached to the outer bottom surface of the inner liner and electrically connected to the ultrasonic generator.

[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0017] 1. An insertion hole is formed through the upper and lower surfaces of the cover, and a flexible light shield that can open and close automatically is set in the insertion hole. When in use, a long strip of dental object can be inserted through the insertion hole, and the dental object will pass through the flexible light shield and extend into the cleaning tank. The flexible light shield can block the ultraviolet light, avoiding ultraviolet light leakage and causing harm to the human body. Therefore, there is no need to open the cover to insert dental objects every time you use it, which brings great convenience to the user.

[0018] Second, by clamping a first sealing ring between the bottom end of the main shell and the top end of the bottom shell, and sealing and fixing the top periphery of the inner liner with the top periphery of the main shell, the first mounting cavity is fully sealed. In addition, a second sealing ring is clamped between the upper cover and the lower cover to achieve a fully sealed state for the second mounting cavity. Thus, this product has excellent sealing and waterproof performance, and can be rinsed as a whole, bringing convenience to its use.

The sealing plug 14 can be opened or closed. When closed, the sealing plug 14 seals and covers the plug hole 103 to achieve a sealing and waterproofing effect.

[0042] The cover 20 is closable and mounted on the base 10. When closed, the cover 20 covers the opening of the cleaning tank 102. The cover 20 has a second mounting cavity 201, and insertion holes 202 for inserting dental instruments are formed through the upper and lower surfaces of the cover 20. The insertion holes 202 communicate with the cleaning tank 102, and a flexible light-shielding member 21 that can open and close automatically is provided in the insertion holes 202. Specifically, the cover 20 includes a lower cover body 22 and an upper cover body 23. The upper cover body 23 and the lower cover body 22 are joined together to form the aforementioned second mounting cavity 201, and a second sealing ring 24 is sandwiched between the upper cover body 23 and the lower cover body 22. The insertion hole 202 passes through the upper cover body 23 and the lower cover body 22, and the periphery of the flexible light-shielding member 21 is clamped between the upper cover body 23 and the lower cover body 22. The lower cover 22 has multiple light-transmitting holes 203 that communicate with the second mounting cavity 201. A light-transmitting sheet 25 is provided in the second mounting cavity 201, sealingly covering the multiple light-transmitting holes 203. The rear edge of the upper cover 23 is hinged to the rear top edge of the main housing 112 of the casing 11, allowing the cover 20 to be rotated vertically relative to the base 10. The flexible light-shielding element 21 is a plastic sheet with a through-hole 211 shaped like a star at the center of its upper and lower surfaces. Furthermore, there are at least two insertion holes 202, which are separately arranged, and each insertion hole 202 contains an automatically opening and closing flexible light-shielding element 21.

[0043] Both the control board 30 and the ultrasonic device 40 are disposed in the first mounting cavity 101. The ultrasonic device 40 is electrically connected to the control board 30 and contacts the outer bottom of the inner liner 12. In this embodiment, the control board 30 has a power interface 31, which is sealed and fitted with the bottom housing 111 and exposed in the insertion hole 103. The control board 30 is also connected to a control switch 32, which is sealed and fitted with the main housing 112 and exposed on the front side of the main housing 112.

After the ultrasonic cleaning and sterilization of the dental objects are completed, turn off the control switch 32, then open the cover 20 and take out the basket 60.

[0048] For long, narrow dental objects (such as toothbrushes), with the cover 20 closed and the ultrasonic device 40 and ultraviolet lamp device 50 in operation, the dental object can be inserted through the insertion hole 202, so that the head of the dental object passes through the flexible light shield 21 and is inserted into the cleaning tank 102 and immersed in the cleaning solution to perform ultrasonic cleaning and sterilization on the head of the dental object. After the ultrasonic cleaning and sterilization of the head of the dental object is completed, the dental object can be pulled out from the insertion hole 202.

[0049] The key design features of this invention are as follows: First, insertion holes are formed through the upper and lower surfaces of the cover, and a flexible, automatically opening and closing light-shielding component is installed within these holes. During use, long dental instruments can be inserted through the insertion holes, passing through the flexible light-shielding component into the cleaning tank. The flexible light-shielding component blocks ultraviolet light, preventing leakage and potential harm to the user. This eliminates the need to open the cover each time, greatly enhancing convenience. Second, a first sealing ring is sandwiched between the bottom of the main housing and the top of the bottom housing, and the top periphery of the inner liner is sealed to the top periphery of the main housing, achieving a fully sealed first mounting cavity. A second sealing ring is sandwiched between the upper and lower covers, achieving a fully sealed second mounting cavity. This provides the product with excellent sealing and waterproofing performance, allowing for complete rinsing and enhancing usability.
