Description

Technical Field

[0001] This utility model relates to the field of testing equipment, specifically to a multifunctional conical flask. Background Technology

[0002] Erlenmeyer flasks are commonly used in chemical experiments for conducting chemical reactions. Their conical shape allows for thorough mixing of the reaction liquid during shaking or stirring, while also effectively preventing splashing. Extraction and separation are also common operations in chemistry teaching. These operations often require a separatory funnel, which necessitates a support frame and involves shaking the liquid inside to ensure thorough mixing before allowing it to settle and separate into layers – a very cumbersome process.

[0003] There is an urgent need for a conical flask capable of performing liquid separation operations to reduce the number of experimental instruments and lower the complexity.

[0004] Therefore, we propose a multifunctional conical flask. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the prior art, this utility model provides a multifunctional conical bottle.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0007] A multifunctional conical flask includes: a flask body, comprising a cylindrical mouth at the top and a conical body at the bottom; an upper liquid outlet located in the middle of the flask body and having an opening and closing structure; a lower liquid outlet located opposite the upper liquid outlet, with the bottom of the lower liquid outlet flush with the bottom surface of the flask body, and also having an opening and closing structure; and a stopper fitted inside the mouth of the flask, wherein a stirring component is provided inside the stopper to stir the liquid inside the flask body.

[0008] By setting an upper liquid outlet in the middle of the bottle and a lower liquid outlet at the bottom, two liquids are added to the bottle during extraction and separation. The mixing is achieved by stirring the liquids with a stirring component on the stopper. After standing and allowing the liquids to separate into layers, separation can be performed. When the separated layer is higher than the upper liquid outlet, the lower liquid outlet is opened first to release the lower liquid. This process continues until the separated layer is almost the same height as the upper liquid outlet. Then, the upper liquid outlet is opened to release the upper liquid. The two liquids are discharged through different outlets, achieving the same function as a separating funnel. However, it does not require a fixing frame or shaking to mix the liquids. It can perform separation and also has the functions of a regular conical flask. It is versatile, simple in structure, and easy to use.

[0009] Further, the upper liquid outlet is set horizontally, and the lower liquid outlet is set upwards; setting the upper liquid outlet horizontally facilitates liquid discharge, and setting the lower liquid outlet upwards facilitates pipeline connection.

[0010] Further defined, the bottle stopper includes a stopper body at the bottom and a limiting shell at the top, the outer diameter of the stopper body and the inner diameter of the bottle mouth are interference fit, and the stopper body is made of a deformable material.

[0011] Further defining the stirring assembly, it includes a stirring rod, a stirring head, stirring blades, a transmission gear, and a drive rack; the transmission gear is horizontally rotatably connected to the limiting shell, the top of the stirring rod passes through the plug and is rotatably connected to the shaft of the transmission gear, the plug has a through hole for the stirring rod to pass through, and there is a gap between the inner wall of the through hole and the outer wall of the stirring rod, the stirring head is fixedly connected to the bottom end of the stirring rod, the stirring blades are evenly spaced on the circumference of the stirring head, and the limiting shell has a stirring hole along the horizontal edge for the drive rack to pass through, the drive rack passes through the stirring hole into the limiting shell and meshes with the transmission gear.

[0012] By setting up a drive rack and a transmission gear meshing, the drive rack can be pushed and pulled manually to achieve forward and reverse rotation of the transmission gear, which in turn drives the stirring blades to rotate in both directions to stir the internal mixed liquid. The advantage of manual pushing and pulling is that the rotation speed of the stirring can be controlled at will.

[0013] Furthermore, the stirring blades are made of a soft material, and in a static state, the stirring blades hang vertically downwards. By making the stirring blades of a soft material, this design can increase the volume of the stirring blades and improve the stirring effect, while also avoiding the difficulty of the blades being too large to fit into or out of the bottle opening.

[0014] Further specifying, the opening and closing structure is a piston; setting the opening and closing structure to be the same as the piston at the bottom of the separating funnel makes it easier to control the liquid discharge rate and reduce the probability of liquid mixing after separation.

[0015] The beneficial effects of this utility model are as follows: by setting the upper liquid outlet and the lower liquid outlet on the bottle body, liquid can be separated by different outlets. Compared with the separating funnel, it does not need to be fixed by a fixed frame or shaken for mixing. It has a simple structure, multiple functions, and is easy to use.

[0020] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0021] Example:

[0022] like Figure 1 and Figure 2 As shown, a multifunctional conical flask includes a bottle body 1, an upper liquid outlet 2, a lower liquid outlet 3, a stopper 4, and a stirring assembly 5. The bottle body 1 includes a bottle mouth 11 with a cylindrical top and a bottle body 12 with a conical bottom. The upper liquid outlet 2 is horizontally located in the middle of the bottle body 12 and is equipped with a piston 6. The lower liquid outlet 3 is opposite to the upper liquid outlet 2, and the bottom of the lower liquid outlet 3 is flush with the bottom surface of the bottle body 12. The lower liquid outlet 3 is also equipped with a piston 6. The lower liquid outlet 3 is inclined upward. The stopper 4 is inserted into the bottle mouth 11, and the stirring assembly 5 is located inside the stopper 4 to stir the liquid in the bottle body 12. The stopper 4 includes a stopper body 42 at the bottom and a limiting shell 41 at the top. The outer diameter of the stopper body 42 and the inner diameter of the bottle mouth 11 are interference-fitted. The stopper body 42 is made of a deformable material. The stirring assembly 5 includes a stirring rod 51, a stirring head 52, and a stirring... The stirring blade 53, the transmission gear 54, and the drive rack 55 are arranged in a series of components. The transmission gear 54 is horizontally rotatably connected to the limiting shell 41. The top of the stirring rod 51 passes through the plug body 42 and is rotatably connected to the shaft of the transmission gear 54. The plug body 42 has a through hole for the stirring rod 51 to pass through, and there is a gap between the inner wall of the through hole and the outer wall of the stirring rod 51. The stirring head 52 is fixedly connected to the bottom end of the stirring rod 51. The stirring blades 53 are evenly spaced on the circumference of the stirring head 52. The limiting shell 41 has a stirring hole 411 horizontally opened on the upper edge for the drive rack 55 to pass through. The drive rack 55 passes through the stirring hole 411 into the limiting shell 41 and meshes with the transmission gear 54. The tail of the drive rack 55 is provided with a pull ring 551. The stirring blades 53 are made of soft material and are vertically hanging down when stationary.

[0023] By setting an upper liquid outlet 2 in the middle of the bottle body 12 and a lower liquid outlet 3 at the bottom, two liquids are added to the bottle body 1 during extraction and separation. The mixing is achieved by stirring the liquids with the stirring component 5 on the stopper 4, allowing them to separate into layers. Once separation is complete, the lower liquid outlet 3 is opened first to release the lower layer of liquid when the layer is almost the same height as the upper liquid outlet 2. Then, the upper liquid outlet 2 is opened to release the upper layer of liquid. The two liquids are discharged through different outlets, achieving the same function as a separating funnel. Furthermore, it does not require a fixing frame or shaking to mix the liquids. It combines the functions of separation with those of a regular conical flask, offering versatility, a simple structure, and ease of use. The design features several advantages: Firstly, the upper liquid outlet 2 is horizontally positioned for easy liquid discharge, while the lower liquid outlet 3 is tilted upwards for convenient pipe connection. Secondly, the active rack 55 meshes with the transmission gear 54, allowing manual pushing and pulling of the active rack 55 to reverse the transmission gear 54, which in turn drives the stirring blades 53 to rotate in both directions to stir the internal mixture. The advantage of manual pushing and pulling is the ability to control the stirring speed. Thirdly, the stirring blades 53 are made of a soft material, which increases their volume and improves the stirring effect while preventing them from becoming too large and causing difficulty in entering and exiting the bottle opening 11. Fourthly, the opening and closing structure is designed to be the same as the piston 6 at the bottom of the separating funnel, making it easier to control the discharge rate and reducing the probability of liquid mixing after separation.
