[0006] Optionally, a movable outlet is further provided in the movable sealing plate, and the movable outlet passes through the outer cavity of the counterweight, and a torsion spring is further connected between the movable sealing plate and the connecting shaft.

[0007] Optionally, the counterweight inner cavity is located at the center of the movable sealing plate, the counterweight outer cavity is fan-shaped, and the counterweight outer cavity is obliquely arranged, and the side of the counterweight outer cavity close to the counterweight inner cavity is lower than the side away from the counterweight inner cavity.

[0008] Optionally, a sealing ring is installed around one side of the fixed outlet close to the movable sealing plate, and the sealing ring abuts against the movable sealing plate.

[0009] Optionally, an angle formed between the movable outlet and the fixed outlet with the connecting axis as the center is between 30° and 90°.

[0010] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. Due to the setting of the sealing component, the movable sealing plate can be set. When the reagent bottle needs to be used intermittently, the reagent bottle can be placed on the desktop. Under the action of the torsion spring on the connecting shaft, the movable outlet and the fixed outlet can be staggered, thereby achieving the effect of automatic sealing, that is, the bottle can be sealed at any time without screwing on the bottle cap, effectively preventing dust from entering the reagent bottle. At this time, if the bottle cap is continued to be screwed on, the double sealing effect can be achieved, thereby enhancing the sealing of the reagent bottle. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0021] As shown in Figure 1-7, a dust-proof reagent bottle includes a bottle body 10, which is characterized in that: a bottle mouth 11 is fixed on the bottle body 10, the bottle mouth 11 is hollow, a sealing assembly is fixed in the bottle mouth 11, the sealing assembly includes a fixed sealing plate 12 fixed on the inner wall of the bottle mouth 11, the bottom of the fixed sealing plate 12 is rotatably connected to a movable sealing plate 14 through a connecting shaft 19, a sealing ring 20 is installed around the side of the fixed outlet 13 close to the movable sealing plate 14, the sealing ring 20 abuts against the movable sealing plate 14, a counterweight outer cavity 15 and a counterweight inner cavity 16 are opened inside the movable sealing plate 14, a plurality of counterweight balls 17 are arranged in the counterweight outer cavity 15 and the counterweight inner cavity 16, the counterweight inner cavity 16 is located at the center of the movable sealing plate 14, the counterweight outer cavity 15 is fan-shaped, and the counterweight outer cavity 15 is obliquely arranged, and the side of the counterweight outer cavity 15 close to the counterweight inner cavity 16 is lower than the side away from the counterweight inner cavity 16.

[0022] A movable outlet 18 is also provided in the movable sealing plate 14, and the movable outlet 18 passes through the counterweight outer cavity 15. A torsion spring is also connected between the movable sealing plate 14 and the connecting shaft 19. The angle formed between the movable outlet 18 and the fixed outlet 13 with the connecting shaft 19 as the center is between 30° and 90°.

[0023] During use, when the reagent bottle is placed on the table, since the counterweight outer cavity 15 is set obliquely, the counterweight ball 17 will be completely stored in the counterweight inner cavity 16. Under the action of the torsion spring on the connecting shaft 19, the movable outlet 18 is staggered with the fixed outlet 13, thereby achieving the effect of automatic sealing. If it is only used temporarily, there is no need to screw on the bottle cap to achieve the effect of sealing at any time, which effectively prevents dust from entering the reagent bottle. At this time, if the bottle cap continues to be screwed on, a double sealing effect can be achieved, thereby enhancing the sealing of the reagent bottle.

[0024] When the liquid in the reagent bottle needs to be poured out, the fixed outlet 13 is directly tilted to the side and downward. At this time, the counterweight ball 17 in the counterweight inner cavity 16 will enter the counterweight outer cavity 15, increasing the weight of the movable sealing plate 14 at the movable outlet 18. The movable outlet 18 can then rotate under the action of gravity to overcome the elastic force of the torsion spring until the movable outlet 18 is connected to the fixed outlet 13, and the liquid can be poured out.

[0025] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
