[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1 and Figure 2 As shown in Example 1, a bottle cap for preventing splashing during the pouring of reagents includes a cover body 5 detachably mounted on the bottle mouth, a pouring spout 3 provided in the middle of the cover body 5, a sealing plug 1 detachably connected to the pouring spout 3, an air guide tube 6 cooperating with the pouring spout 3 provided on the cover body 5, and an air guide tube plug 7 detachably connected to the air guide tube 6. The anti-splash bottle cap extends the service life of experimental equipment, saves experimental costs and manpower and material resources, makes pouring liquids faster and smoother, reduces the error rate, ensures the safety of experimental personnel, and improves the operability of the experiment.

[0027] In this embodiment, the cover body 5 is provided with a pipe fitting 4 for connecting to the bottle body, and the pouring spout 3 is provided on the pipe fitting 4. The pouring spout 3 includes a V-shaped guide port, which is provided on the upper part of the pipe fitting 4. A transition outer edge is provided between the V-shaped guide port and the pipe fitting 4, and the transition outer edge is flush with the upper plane of the pouring spout. The V-shaped guide port serves as a guide outlet for pouring, which can ensure that the reagents are gathered together to form a thin stream of water when poured out, which can buffer the liquid and greatly prevent the reagents from spilling or splashing. The sealing plug 1 is provided with a connector 2 connected to the pipe fitting 4. The connector 2 includes a connecting rope, and the other end of the connecting rope is connected to a buckle, which is provided on the pipe fitting 4. The connecting rope and the buckle are both elastic structural parts used to always connect the sealing plug 1 to the pipe fitting 4.

[0028] In the present embodiment, the air duct 6 is a "7"-shaped air duct 6. The air duct 6 includes a vertical tube, the upper portion of the vertical tube is connected to a vertically arranged horizontal tube, the lower portion of the vertical tube is connected to an oblique tube arranged obliquely, the horizontal tube, the vertical tube and the oblique tube are an integrally formed structure, and the end of the oblique tube is arranged close to the inner wall of the reagent bottle to prevent the gas entering through the air duct 6 during the pouring process from affecting the stable outflow of the liquid. The air duct 6 is a polypropylene tube or a polytetrafluoroethylene tube or a high-density polyethylene tube or a styrene-butadiene rubber tube. As an additional small branch tube, the air duct 6 can balance the air pressure, allowing the liquid to be poured out more smoothly.

[0029] In this embodiment, the inner wall of the cover 5 is provided with an internal thread that cooperates with the bottle mouth. The spiral pattern provided in the cover 5 can tightly fit together with the reagent bottle, ensuring that the cover 5 can seal the reagent bottle and prevent leakage from the connection. The inner wall of the cover 5 is provided with an annular protrusion that cooperates with the bottle mouth, and the annular protrusion is provided with a plurality of annular grooves. The annular grooves cooperate with the annular protrusion to facilitate the sealing of the cover 5 at the bottle mouth of the reagent bottle.

[0030] like Figure 1 As shown in Example 2, a bottle cap for preventing splashing during the pouring process of a reagent comprises

[0031] Sealing plug: used to seal the bottle mouth to prevent the reagent in the bottle from being contaminated when not in use;

[0032] Pour mouth: The pointed mouth is convenient for pouring reagents and making it easier to take them;

[0033] Cap: Use threaded connection between the bottle mouth and the bottle cap to ensure good sealing performance and replace the original bottle cap handle to avoid the tedious operation of changing the cap back and forth;

[0034] Air guide tube: Balances the air pressure to facilitate smooth outflow of liquid and avoids the impact of air pressure difference when pouring liquid.

[0035] Airway Plug: Seals the airway to prevent contamination of the reagents in the bottle when not in use. The seal, cap, airway, and airway plug can be made of materials such as polypropylene (PP), polytetrafluoroethylene (PTFE), high-density polyethylene (HDPE), and styrene-butadiene rubber (BR). This innovative feature enhances the safety and operability of chemical experiments and production processes, while also adding a splash-proof function to the existing solution pouring function.

[0036] When in use, replace the original bottle cap with a splash-proof bottle cap. When pouring liquid, the design of the pouring spout ensures smooth liquid flow and eliminates the need for water cut-off. When there is too much liquid in the bottle and it is difficult to flow out, open the air tube plug. The design of the air tube is conducive to balancing the air pressure inside and outside the bottle. The design of the sealing plug and the air tube plug prevents the liquid from deteriorating when in contact with air during storage.

[0037] Specifically, this device can improve user experience. Avoiding spills during liquid transfers in the laboratory can reduce unnecessary hassles and cleaning work. This design allows users to transfer and use liquids more easily and conveniently.

[0038] Improve laboratory safety. When handling toxic, hazardous, or flammable liquids, spills can lead to serious consequences such as environmental pollution, personal injury, and even fire. Innovative designs can reduce or prevent these spills, effectively ensuring personnel safety and environmental protection.

[0039] This device uses polypropylene (PP), polytetrafluoroethylene (PTFE), high-density polyethylene (HDPE), or styrene-butadiene rubber (BR) materials to promote efficient resource utilization. In daily life and industrial production, liquid spills often mean resource loss. Reducing this loss through innovative design not only reduces production costs but also improves resource utilization efficiency, in line with the concept of sustainable development.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
