[0017] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0018] In one embodiment, Figure 1-Figure 6 As shown: The present embodiment provides an oral impression disinfection device, including a disinfection cabin 1, a disinfection seat 2 is provided in the disinfection cabin 1, a support frame 3 is provided in the disinfection cabin 1, the support frame 3 is located below the disinfection seat 2, a lifting column 4 is connected to the bottom of the disinfection seat 2, a support spring 6 is sleeved on the lifting column 4, the top end of the support spring 6 is supported on the bottom surface of the disinfection seat 2, and the bottom end of the support spring 6 is supported on the support frame 3, a swing rod 5 is provided in the disinfection cabin 1, the lifting column 4 passes downward through the support frame 3 and is hinged on the swing rod 5, when the swing rod 5 swings downward, it brings the lifting column 4 down, and the lifting column 4 is lifted by the lifting rod 5. The descending column 4 drives the disinfection seat 2 to descend. A plurality of immersion holes 7 are provided at the bottom of the disinfection seat 2. The disinfection chamber 1 is filled with disinfectant. The liquid level of the disinfectant is close to the bottom surface of the disinfection seat 2. A cover 8 is hinged on the top of the disinfection seat 2. A hole 9 is provided on the cover 8. A disinfection tube 10 is installed in the disinfection chamber 1. The disinfection tube 10 corresponds to the top of the hole 9 and is on the same vertical axis as the hole 9. The cover 8 can be opened upward. When the disinfection seat 2 descends, the disinfectant in the disinfection chamber 1 is immersed into the disinfection seat 2 through the immersion holes 7, and the oral impression is immersed and disinfected; When the disinfection seat 2 descends, the cover 8 will also be brought down with it, so that the hole 9 on the cover 8 is moved downward away from the disinfection tube 10. When the disinfection seat 2 rises with the cover 8, the bottom of the disinfection seat 2 is separated upward from the disinfectant in the disinfection chamber 1, and the disinfectant immersed in the disinfection seat 2 leaks into the disinfection chamber 1 through the immersion hole 7. When the disinfection seat 2 rises with the cover 8, the hole 9 will also rise along the disinfection tube 10, and the disinfection tube 10 will be inserted into the disinfection seat 2, so as to perform secondary sterilization on the oral cavity impression whose moisture is controlled in the disinfection seat 2.

[0019] When in use, the cover 8 is opened, and the concave surface of the oral impression is placed downward in the disinfection seat 2. Since a plurality of support rods 11 are provided in the disinfection seat 2, when the oral impression is placed in the disinfection seat 2, the concave surface is pressed downward. Figure 1The shape shown is supported on the top of the support rod 11, that is, the open end of the impression faces downward), and it is convenient to quickly control the liquid after soaking in the disinfectant. The oral impression forms an immersion space between the disinfection seat 2 and the immersion hole 7, and the cover 8 is closed. The swing rod 5 is operated to bring the lifting column 4 down, and the lifting column 4 brings the disinfection seat 2 down, so that the disinfection seat 2 with the immersion hole 7 sinks into the disinfectant. The disinfectant is poured into the disinfection seat 2 from the immersion hole 7 and does not cover the oral impression, so that the oral impression is immersed and disinfected. After a few seconds, the swing rod 5 is operated to deflect upward, and the swing rod 5 brings the lifting column 4 up, and the lifting column 4 brings the disinfection seat 2 up, so that the disinfection seat 2 leaves the disinfectant and rises. As the disinfection seat 2 rises, the disinfectant falls back into the disinfection cabin 1 through the immersion hole 7, and the disinfectant residue on the oral impression will also drip rapidly downward along the surface of the impression, avoiding deformation of the impression caused by long-term immersion in the disinfectant. The swing rod 5 is operated to deflect up and down frequently, and the lifting column 4 is lifted and lowered frequently, and the lifting column 4 is used to drive the disinfection seat 2 to frequently reciprocate in the disinfectant, and the residual disinfectant is quickly drained after each disinfection of the oral impression, so that the oral impression is immersed in the disinfectant again for disinfection, and the disinfection quality is greatly improved. Moreover, this fast soaking and fast drying method can prevent the impression from being deformed due to being immersed in the liquid for a long time.

[0020] Each time the disinfection seat 2 rises, the hole 9 at the top thereof will rise once along the disinfection tube 10 (ultraviolet disinfection lamp), and each time the disinfection seat 2 rises along the disinfection tube 10, the disinfection tube 10 will be close to the oral cavity impression once, and the disinfection light emitted by the disinfection tube 10 will be shot into the disinfection seat 2 and reflected onto the oral cavity impression, so that the oral cavity impression is sterilized for a second time. When the disinfection seat 2 rises, it is taking the oral cavity impression away from the disinfectant, and the disinfectant on the surface of the oral cavity impression is controlled downward to dry, thereby enabling the disinfection light to be better shot onto the oral cavity impression. The oral cavity impression is subjected to multiple immersions and multiple light sterilization treatments, so that the disinfection efficiency is greatly improved. After the oral cavity impression is taken out, it does not need to be manually dried by suction paper, and no additional waste is generated. During the disinfection process, the operation is standardized relative to a closed environment.

[0021] The top of the disinfection cabin 1 is provided with a top seat 13, on which an electrical box 14 is installed, and the top end of the disinfection tube 10 is connected to the bottom surface of the top seat 13 and is electrically connected to the electrical box 14; the electrical box 14 includes at least a timing module, and the electric cylinder 16 is electrically connected to the timing module, and the timing module connects the electric cylinder 16 and the disinfection tube 10. During actual assembly, an operation panel will be installed outside the disinfection cabin 1, and the user inputs the timing time through the buttons on the operation panel. The timing module controls the working time of the electric cylinder 16 according to the set timing time, and also controls the working time of the disinfection tube 10. After the electric cylinder 16 and the disinfection tube 10 work within the set time, the disinfection work is stopped, and the appropriate disinfection time is selected for oral prints of different materials to disinfect them.

[0022] The top seat 13 is a rubber seat, which can be bent up and down. When the oral impression is placed in the disinfection seat 2, the top seat 13 is first bent upward, and the disinfection seat 2 is moved downward to make the disinfection seat 2 descend with the hole 9, so that the hole 9 leaves the disinfection tube 10, and then the cover 8 is opened upward.

[0023] In another embodiment, a connecting seat 12 is installed on the periphery of the disinfection seat 2, and the outer surface of the connecting seat 12 slides on the inner wall surface of the disinfection chamber 1, and the connecting seat 12 plays a role in guiding the disinfection seat 2 to be smoothly raised or lowered.

[0024] A track 15 is provided on the inner wall of one side of the disinfection chamber 1, and an electric cylinder 16 is installed in the track 15. The track 15 is connected to the inner cavity of the disinfection chamber 1. One end of the swing rod 5 extends to the track 15 and is installed with a pressure rod 17. The action rod of the electric cylinder 16 extends vertically downward along the track 15 and is installed with a pressure frame 18. One end of the pressure frame 18 extends into the disinfection chamber 1 along the track 15 and presses on the pressure rod 17. The other end of the swing rod 5 is tilted downward and transferred to the inner wall of the other side of the disinfection chamber 1. A rotating shaft 24 is provided in the middle of the swing rod 5, and the rotating shaft 24 is also transferred to the bottom end of the lifting column 4. The electric cylinder 16 is electrically connected to the timing module in the electrical box 14.

[0025] like Figure 2 , Figure 3As shown, the disinfection tube 10 is a composite structure. The disinfection tube 10 is composed of an outer rubber tube 19 and a plurality of lamp tube units 20 bound in the rubber tube 19. All the lamp tube units 20 are electrically connected in series with each other in the rubber tube 19 and are connected to the electrical box 14. The lamp tube units 20 are LED light strips. All the parts of the lamp tube units 20 exposed at the bottom of the rubber tube 19 are bent toward the surrounding direction. A control sleeve 21 that can move up and down is sleeved on the outer wall of the rubber tube 19. A spring 22 is sleeved on the outer periphery of the rubber tube 19. The top end of the spring 22 is elastically supported on the top seat 13, and the bottom end of the spring 22 is elastically supported on the control sleeve 21. A metal ring 23 is fixed to the bottom end of the rubber tube 19. The control sleeve 21 is located above the metal ring 23. The metal ring 23 prevents the control sleeve 21 from falling off from the rubber tube 19. The aperture of the hole 9 is larger than the outer diameter of the metal ring 23, and the aperture of the hole 9 is smaller than the outer diameter of the control sleeve 21. The outer diameter of the sleeve 21; when the disinfection seat 2 rises with the oral impression, it will also rise with the cover 8, and the cover 8 will rise along the rubber tube 19 with the hole 9, and the cover 8 will also hit the bottom surface of the control sleeve 21 while rising, pushing the control sleeve 21 to rise, and the spring 22 is compressed to shorten and store elastic force. When the control sleeve 21 rises, it is equivalent to making the distance between the control sleeve 21 and the bottom curved part of the lamp tube unit 20 gradually become farther, thereby making the clamping force of the control sleeve 21 on its curved part smaller, and at the same time, the relaxation degree of the bottom end of the rubber tube 19 becomes larger, and the restraining force on the bottom curved part of the lamp tube unit 20 is reduced. As the disinfection seat 2 continues to rise, and the hole 9 passes over the metal ring 23 to the top of the metal ring 23, in addition to gradually approaching these lamp tube units 20 with the oral impression, these lamp tube units 20 will further release the bending degree toward the outer direction due to the reduction of the restraining force, so that their curved parts are Figure 1 The shape shown is filled in the disinfection seat 2, increasing the sterilization area. When the disinfection seat 2 descends, the thrust of the cover 8 on the control sleeve 21 is reduced, and the spring 22 changes from being compressed and shortened to being elastic and lengthened. At this time, the bottom end of the spring 22 pushes the control sleeve 21 to slide along the rubber tube 19 until the control sleeve 21 falls on the metal ring 23. After the control sleeve 21 descends, it will approach the curved sections of these lamp tube units 20, thereby forcing their bending degrees to become smaller, preventing obstructive effects on the continued descent of the disinfection seat 2. The disinfection seat 2 continues to descend for a distance and then falls into the disinfectant, and the disinfectant is poured into the seat through the immersion hole 7.

[0026] The timing module in the electrical box 14 controls the frequent telescopic movement of the action rod of the electric cylinder 16, which drives the frequent lifting and lowering movement of the pressure frame 18 by the action rod, and the inner end of the pressure frame 18 drives the frequent lifting and lowering movement of the pressure rod 17, which drives the pendulum rod 5 to frequently deflect up and down, and the pendulum rod 5 drives the lifting column 4 to frequently lift and lower, and the lifting column 4 drives the disinfection seat 2 to frequently lift and lower, and the disinfection seat 2 drives the oral impression to work back and forth between disinfectant immersion and ultraviolet sterilization, thereby realizing automation and accelerating disinfection efficiency. In addition, a display screen is installed on the disinfection cabin 1, and the display screen has a timing display function for observing the processing time. There is a button near the display screen. The operator only needs to start the button to start the work, and can also stop the work according to the timing time.

[0027] It should be particularly pointed out that in order to make the structure more reasonable, facilitate the opening of the cover 8, and make it convenient to put the oral impression into the disinfection seat 2, the installation method of the cover 8 in the present invention is not limited to rotating up and down. Figure 6 As shown, the cover 8 can also be installed on the disinfection seat 2 in other ways, for example, a pin is installed at the top of the disinfection seat 2, and the cover 8 is installed on the pin. In order to facilitate the opening of the cover 8, the cover 8 can also be made into two semicircular shapes, and the two semicircular parts are respectively installed on the pins. The two semicircular parts are installed on the disinfection seat 2 through the pins in a forward and backward rotating manner, that is, the hole 9 is divided into two parts along with the two semicircular parts. When opening, the two semicircular parts are rotated to both sides to open, and then the oral impression is placed in the disinfection seat 2.

[0028] A method for disinfecting an oral impression comprises the following disinfection steps: Step S01, a disinfectant is added into the disinfection chamber 1, wherein the disinfectant is a sodium chlorate solution added to water at a ratio of 0.5%; Step S02, turn the oral cavity impression upside down, place the oral cavity impression with the concave side facing downward in the disinfection seat 2, and support the concave side with the support rod 11 to form a distance between the oral cavity impression and the immersion hole 7; Step S03, the lifting column 4 drives the disinfection seat 2 to move up and down, and the oral impression is reciprocated between the disinfectant and the disinfection tube 10 to speed up the disinfection efficiency.

[0029] The lamp tube unit mentioned in the present invention is an LED light strip, such as a UV sterilizing soft light strip, and the electric cylinder mentioned in the present invention is a micro electric cylinder.

[0030] The pressure rod, pressure frame, rocker arm and other structures mentioned in the present invention can be simply understood as the connecting rod structure commonly used in mechanical transmission. The connecting rod structure is a common prior art in mechanical transmission, so its specific structure and length setting are not repeated in the present invention.
