Description

Technical Field

[0001] This utility model relates to the field of nucleic acid contaminant removal technology, and in particular to a nucleic acid contaminant spray removal device. Background Technology

[0002] In molecular biology laboratories, the presence of suspended DNA or RNA particles can lead to false positives in PCR results. Nucleic acid contaminants are cumulative and persistent and difficult to remove. Therefore, nucleic acid contaminant removal sprays are used in experiments to clean nucleic acid contaminants from the surface of instruments.

[0003] Most existing nucleic acid contaminant removal solutions are bottled, sprayed out by a press-type nozzle on the bottle to treat suspended DNA or RNA particles. Afterward, wiping with laboratory paper completes the removal of nucleic acid contaminants. However, because the press mechanism at the nozzle cannot be reattached after the retaining pin is removed, the solution may still be accidentally sprayed out even after use, leading to waste. Therefore, we propose a nucleic acid contaminant spray removal device to solve this problem. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a nucleic acid contaminant spray removal device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a nucleic acid contaminant spray removal device is designed, including a bottle body, a nozzle installed on the top of the bottle body, and limiting plates provided on both sides of the nozzle. The bottom sides of the limiting plates are rotatably mounted on fixed seats via rotating shafts, and the fixed seats are fixed to the bottle body. A torsion spring is sleeved on the rotating shaft, one end of the torsion spring is fixed to the fixed seat, and the other end of the torsion spring is fixed to the limiting plate. A wedge-shaped limiting groove is opened on the top side of the limiting plate near the nozzle.

[0006] A sleeve is fitted on the top of the bottle mouth, and the inner wall of the sleeve is threaded to the outer wall of the bottle mouth. A press pump is installed inside the sleeve, and a suction tube is connected to the bottom of the press pump. A press seat is installed on the top of the press pump. The press seat is a sleeve with an open bottom and is fitted on the sleeve. A nozzle is provided on the side of the press seat and is connected to the press pump through a conduit.

[0007] Wedge-shaped limiting blocks are installed on both sides of the bottom of the pressing seat. The limiting blocks correspond to the limiting grooves. The top of the limiting blocks is a horizontal plane, and the bottom of the limiting blocks is an inclined slope.

[0008] Preferably, the frontal projection of the limiting block is located on both sides of the nozzle.

[0009] Preferably, the suction pipe is a soft tube, and a counterweight is installed at the bottom of the suction pipe.

DETAILED DESCRIPTION

[0022] Clearly and completely describe the technical scheme in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all.

[0023] Referring to Figures 1-4 A nucleic acid contaminant spray removal device, comprising a bottle body 1, a bottle mouth 2 is installed at the top of the bottle body 1, a sleeve 3 is sleeved on the top of the bottle mouth 2, and the inner wall of the sleeve 3 is threadedly connected with the outer wall of the bottle mouth 2, and in order to ensure that the sleeve 3 seals the port of the bottle mouth 2 on the bottle mouth 2, a sealing gasket is installed at the top of the bottle mouth 2, and the sealing gasket corresponds to the top in the sleeve 3.

[0024] As Figure 3 and Figure 4 shown, a pressing pump 4 is arranged in the sleeve 3, and the bottom of the pressing pump 4 is connected with a suction pipe 6, wherein the suction pipe 6 is a hose, and a counterweight 7 is installed at the bottom of the suction pipe 6, so that after the suction pipe 6 is placed in the bottle body 1, the port of the suction pipe 6 is always located at the bottom of the bottle body 1, ensuring that the pressing pump 4 can fully extract the liquid in the bottle body 1; and a pressing seat 5 is installed at the top of the pressing pump 4, the pressing seat 5 is a sleeve with an open bottom and is sleeved on the sleeve 3, a spray head 9 is arranged on the side surface of the pressing seat 5, and the spray head 9 is connected with the pressing pump 4 through a conduit, when the pressing seat 5 is pressed downward, the liquid in the bottle body 1 can be extracted and sprayed from the spray head 9, thereby removing the nucleic acid contaminants.

[0025] As Figure 1 and Figure 2 shown, a limiting plate 11 is arranged on both sides of the bottle mouth 2, the front view projection of the limiting block 8 is located on both sides of the spray head 9, the bottom of the limiting plate 11 is rotatably installed on the fixed seat 14 through the rotating shaft 13 on both sides, and the fixed seat 14 is fixed on the bottle body 1, a torsional spring 15 is sleeved on the rotating shaft 13, one end of the torsional spring 15 is fixed on the fixed seat 14, and the other end of the torsional spring 15 is fixed on the limiting plate 11, a wedge-shaped limiting groove 12 is opened at the top of the side of the limiting plate 11 close to the bottle mouth 2, and under the action of the torsional spring 15, the limiting plate 11 always has a tendency to rotate towards the bottle mouth 2, that is, when not in use, the limiting plate 11 will be attached to the outer wall of the bottle mouth 2 under the action of the torsional spring 15, so that the top of the limiting plate 11 will be opposite to the bottom of the pressing seat 5, thereby resisting the pressing seat 5, so that the pressing seat 5 cannot be pressed down, and when the nucleic acid contaminants do not need to be removed, the situation that the liquid in the bottle body 1 is wasted due to the pressing seat 5 being accidentally touched can be avoided.

[0026] When the nucleic acid contaminant needs to be removed, the wedge-shaped limiting blocks 8 are installed on the two side bottoms of the pressing seat 5, the limiting blocks 8 correspond to the limiting grooves 12, the top of the limiting blocks 8 is a horizontal plane, and the bottom is an inclined slope, which can push the limiting plate 11 outward, and in order to make the stress rotation of the limiting plate 11 more labor-saving, the arc-shaped pushing plate 16 is connected to the side of the limiting plate 11 away from the bottle mouth 2, the inner side of the pushing plate 16 is downwardly arranged, that is, the fingers can be directly pressed on the inner side of the pushing plate 16, so as to drive the limiting plate 11 to rotate outward, then only needs to slightly press the pressing seat 5, and the limiting blocks 8 on both sides of the pressing seat 5 are placed in the limiting grooves 12 of the limiting plate 11, at this time, the limiting plate 11 will be tightly attached to the pressing seat 5 under the action of the torsion spring 15, and the limiting of the limiting blocks 8 also makes the limiting plate 11 unable to rotate back to the bottle mouth 2, so that the pressing seat 5 can be hindered by repeated pressing.

[0027] Further, the arc-shaped pressing plate 10 is arranged above the pressing seat 5, the bottom of the pressing plate 10 is rotationally connected with the pressing seat 5, when the pressing seat 5 is pressed, the fingers can be placed on the pressing plate 10, and the arc-shaped structure of the pressing plate 10 can be more fitted to the fingers, so as to facilitate the force exertion when pressing.

[0028] It should be noted that, as shown in Figure 1 The L-shaped plate 17 is arranged on the side of the bottle body 1 close to the spray head 9, the top of the L-shaped plate 17 is fixed with the top of the bottle body 1, when in use, part of the fingers can be inserted into the inner side of the L-shaped plate 17, and the fingers for pressing the pressing seat 5 are placed on the pressing plate 10, so that the whole bottle body 1 can be held on the hand, which facilitates the single-handed operation when spraying the liquid, and improves the stability of the single-handed holding of the bottle body 1.

[0029] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
