DETAILED DESCRIPTION
[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0024] like Figure 1-7 As shown, a sterilization device for cleaning a nucleic acid extraction instrument comprises a shell 1, the top of the shell 1 is fixedly connected to an air pipe 1 2, and the bottom of the shell 1 is fixedly connected to an air pipe 2 3, the front of the shell 1 is rotatably connected to a flip cover 4, and a rotating mechanism 5 is provided at the inner bottom of the shell 1, the rotating mechanism 5 comprises a toothed disc 6, the bottom of the toothed disc 6 is rotatably connected to the shell 1, and one side of the toothed disc 6 is meshingly connected to a gear 7, one side of the gear 7 is fixedly connected to a handle 8, the inner side of the toothed disc 6 is rotatably connected to a two-way worm 12, both ends of the two-way worm 12 are meshingly connected to a slider 13, the bottoms of the two sliders 13 are slidably connected to the toothed disc 6, one side of the inner part of the shell 1 is fixedly connected to a vertical rod 9, one side of the vertical rod 9 is fixedly connected to a plurality of brushes 11, and the top of the vertical rod 9 is rotatably connected to two rubber pads 14, a cross bar 10 is rotatably connected between the two rubber pads 14, and the bottom of the cross bar 10 is also fixedly connected to a plurality of brushes 11.
[0025] In this embodiment, the inner side of the air pipe 2 3 is fixedly connected to the wind shield 15 , the bottom of the air shield 15 is fixedly connected to the capillary 16 , and the bottom of the air pipe 2 3 is meshedly connected to the round bottle 17 .
[0026] By setting the wind shield 15, the air pressure increases when the air flows through, so that the air flow speed inside the wind shield 15 is accelerated, and a pressure difference is formed with the round bottle 17, so that the gas or liquid in the round bottle 17 is brought into the top of the capillary 16 by the air pressure, and the round bottle 17 is filled with either chlorine dioxide solution or alcohol.
[0027] In this embodiment, both ends of the wind shield 15 are trumpet-shaped, and a round hole is opened at the bottom of the wind shield 15 .
[0028] The trumpet-shaped shape of the air shield 15 is more conducive to the gathering and diffusion of airflow, and the circular hole at the bottom enables liquid or gas to enter the interior of the air shield 15 .
[0029] In this embodiment, a T-shaped slot is formed on the top of the toothed disc 6 , and through circular holes are formed at both ends of the T-shaped slot.
[0030] The toothed disc 6 accommodates the slider 13 and the bidirectional worm 12 through the T-shaped groove, and the bidirectional worm 12 can rotate inside the toothed disc 6 through the circular hole.
[0031] In this embodiment, a circular hole is opened on one side of the housing 1 and passes through from the inside to the outside, and one end of the handle 8 passes through the circular hole to the outside of the housing 1.
[0032] One end of the handle 8 passes through the circular hole and is connected to the gear 7. The housing 1 limits the movement of the handle 8 through the circular hole, so that the handle 8 can only rotate in the original position.
[0033] In this embodiment, the two sliders 13 are in an inverted T-shape, and a through screw hole is formed on one side of the two sliders 13 .
[0034] The shapes of the two sliders 13 match the grooves of the toothed disc 6 , so that they can move along the grooves inside the toothed disc 6 , and the bidirectional worm 12 provides power through the screw holes of the two sliders 13 .
[0035] In this embodiment, a circular protrusion is provided at one end of the bidirectional worm 12 , and a vertical circular protrusion is provided at the other end of the bidirectional worm 12 .
[0036] By applying a force to a circular protrusion perpendicular to the other end of the bidirectional worm 12 , the bidirectional worm 12 can be rotated, thereby driving the two sliders 13 to start moving.
[0037] It should be noted that the utility model is a sterilization device for cleaning a nucleic acid extraction instrument, which can clamp the nucleic acid extraction instrument when in use. The specific operation method is to open the flip cover 4 at the front of the housing 1, place the nucleic acid extraction instrument in the center of the top of the toothed disc 6, and after the nucleic acid extraction instrument is placed, rotate the bidirectional worm 12;
[0038] Since both ends of the bidirectional worm 12 are restricted by the toothed disc 6, it can only rotate in place when subjected to force. The bidirectional worm 12 drives the two sliders 13 to move through meshing when rotating, and due to the effect of threads in different directions on the bidirectional worm 12, the two sliders 13 will move in opposite directions. At the same time, the two sliders 13 can only move along the direction of the T-shaped groove under the restriction of the T-shaped groove of the toothed disc 6.
[0039] Rotating the bidirectional worm 12 in different directions can control the two sliders 13 to move closer and farther away, and control the two sliders 13 to move closer to each other until the two sliders 13 clamp the nucleic acid extraction instrument. After the nucleic acid extraction instrument is clamped, the nucleic acid extraction instrument will not be displaced or shaken during disinfection and cleaning, thereby avoiding the cleaning effect. When the nucleic acid extraction instrument is clamped, one end of the plurality of brushes 11 on the horizontal bar 10 and the vertical bar 9 contacts the surface of the nucleic acid extraction instrument;
[0040] After the nucleic acid extraction instrument is clamped stably, the flip cover 4 is closed, and then the handle 8 is turned. When the handle 8 is turned, the gear 7 is driven to rotate together, and the gear 7 drives the toothed disc 6 to rotate together through meshing action. After the toothed disc 6 rotates, the nucleic acid extraction instrument is driven to rotate in the same direction. While the nucleic acid extraction instrument is rotating, the brush 11 cleans the surface of the nucleic acid extraction instrument to remove dust and dirt outside the nucleic acid extraction instrument;
[0041] The nucleic acid extraction instrument cleaning sterilization device can sterilize the nucleic acid extraction instrument by gas and spray. When sterilizing by gas, the specific operation method is to connect ozone to the air pipe 2 3 so that the ozone slowly enters the housing 1 of the nucleic acid extraction instrument cleaning sterilization device;
[0042] Since the density of ozone is greater than that of air, when ozone is slowly injected into the housing 1, the ozone will first be deposited at the bottom of the inner side of the housing 1, and as the amount of ozone injected increases, the air in the housing 1 is squeezed out of the housing 1 through the air pipe 2, and the nucleic acid extraction instrument is wrapped by ozone, and the strong oxidizing property of ozone is used to sterilize;
[0043] Since ozone is not easy to preserve, it usually requires special equipment to produce it. When there is no special ozone production equipment, chlorine dioxide solution can be added to the round bottle 17, and the liquid level of the chlorine dioxide solution is lower than the bottom of the capillary 16. The chlorine dioxide solution will continuously evaporate chlorine dioxide gas, and then the air flow is connected to the air pipe 23. The air flow is blocked when passing through the wind shield 15, and the air flow speed increases when passing through the middle of the wind shield 15, so that the air pressure in the middle of the wind shield 15 is lower than that of the round bottle 17;
[0044] Under the action of Bernoulli's principle, high-pressure gas or fluid transfers to low pressure, and the chlorine dioxide gas in the round bottle 17 will flow to the inside of the wind shield 15 through the capillary 16 under the action of the pressure difference, and enter the inside of the housing 1 along with the air flow, thereby sterilizing the nucleic acid extraction instrument through the chlorine dioxide gas;
[0045] If the nucleic acid extraction instrument has a waterproof function, or when the instrument needs to be cleaned, the instrument can be waterproofed and then placed in the toothed disc 6 for clamping, and alcohol can be filled in the round bottle 17, and the liquid level can be higher than the bottom of the capillary 16, and then the air pipe 23 can be connected to the high-speed airflow, and the alcohol liquid in the round bottle 17 can enter the wind shield 15 through the capillary 16, and be broken into mist by the high-speed airflow and sprayed into the housing 1, thereby spraying onto the surface of the nucleic acid extraction instrument, and the nucleic acid extraction instrument can be scrubbed with the help of the brush 11;
[0046] By providing the rotating mechanism 5 and the wind shield 15, the surface of the nucleic acid extraction instrument can be cleaned, and the nucleic acid extraction instrument can be sterilized by gas and liquid, so that the instrument can be cleaned while being sterilized, thereby reducing the time for sterilization and cleaning, improving efficiency, and keeping the inside and outside of the nucleic acid extraction instrument clean, thereby reducing the risk of sample contamination.
[0047] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
