Description

Technical Field

[0001] The utility model belongs to the technical field of laboratory instruments, and in particular relates to a flow guide funnel. Background Art

[0002] Glass rods are commonly used in laboratories. One of the functions of glass rods is to drain fluids. Glass rods are needed for drainage during filtration or fluid transfer. However, in actual operations, accidents often occur when the fluid is poured onto the outer wall of the glass rod. Pouring too fast or the inclination of the glass rod is not appropriate, which can cause the fluid to splash or drip onto other areas or the operator.

[0003] In order to reduce the risk in the glass rod drainage operation, a diversion funnel can be configured on the glass rod to reduce the occurrence of accidents. Utility Model Content

[0004] The utility model aims to provide a flow guide funnel, wherein the fluid enters the funnel by pouring, finally flows along the inner wall of the funnel to the surface of the glass rod, and then is drained by the glass rod, thereby preventing the occurrence of problems such as fluid splashing and spilling caused by improper operation.

[0005] In order to achieve the above purpose, the technical solution of the utility model is to design a diversion funnel, which is installed on a drainage rod (i.e., a glass rod) for use, including a funnel and a mounting sleeve for connecting the drainage rod; the outer wall of the mounting sleeve is connected to the funnel, and the funnel is wide at the top and narrow at the bottom.

[0006] Furthermore, the installation sleeve is an elastic sleeve structure with an opening on one side.

[0007] Furthermore, the funnel and the mounting sleeve maintain a relatively inclined state.

[0008] Furthermore, the outer wall of the far end of the funnel forms an inwardly curved surface.

[0009] Furthermore, protective walls are respectively provided on both sides of the proximal end of the lower edge of the funnel.

[0010] Furthermore, a slope is provided at the lower portion of the mounting sleeve, located at the lower edge of the funnel.

[0011] Furthermore, an anti-slip end is provided on the upper portion of the mounting sleeve.

[0012] Furthermore, the lower edge of the funnel extends downward to form a baffle, and both sides of the baffle are connected to the mounting sleeve.

[0013] The advantages and beneficial effects of the utility model are as follows: the utility model provides a diversion funnel, the fluid enters the funnel by pouring, and finally flows along the inner wall of the funnel to the surface of the glass rod, and then is drained by the glass rod, which can prevent the occurrence of problems such as fluid splashing and spilling caused by improper operation.

[0021] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0022] Embodiment 1:

[0023] like Figure 2 , Figure 3 As shown, a guide funnel comprises a funnel 1 and a mounting sleeve 2; the mounting sleeve 2 is an elastic clamping sleeve structure with one side open, and a glass rod A can be clamped into the mounting sleeve 2 along one side of the opening of the mounting sleeve 2.

[0024] The outer wall of the mounting sleeve 2 is connected to a funnel 1, which is wide at the top and narrow at the bottom. The funnel 1 and the mounting sleeve 2 are kept in a relatively inclined state. When the glass rod A is tilted and placed into the beaker B, the inclination angle between the mounting sleeve 2 and the horizontal plane is consistent with the inclination angle between the glass rod A and the horizontal plane. Since there is a certain angle between the funnel 1 and the mounting sleeve 2, the mounting sleeve 2 is tilted, and the funnel 1 is lifted upward to obtain a certain inclination supplement. At this time, the inclination angle between the funnel 1 and the horizontal plane is small, which is conducive to the smooth entry of the fluid into the funnel 1 on the one hand, and prevents the fluid from splashing out of the funnel 1 on the other hand.

[0025] The outer wall of the far end of the funnel 1 (the far end is the end of the funnel 1 away from the mounting sleeve 2) forms an inward arc surface D, which is conducive to the fluid flowing downward along the arc surface D, reducing the sputtering caused by the fluid directly impacting the inner wall of the funnel 1. In addition, the fluid can also be guided toward the direction of the glass rod A.

[0026] Protective walls 4 are respectively provided on both sides of the proximal end of the lower edge of the funnel 1 (the proximal end is the end where the funnel 1 is connected to the mounting sleeve 2), which also serves the purpose of preventing splashing.

[0027] A slope 5 is provided at the lower part of the mounting sleeve 2 , at the lower edge of the funnel 1 . Since the mounting sleeve 2 is between the glass rod A and the funnel 1 , when the fluid flows out from the lower edge of the funnel 1 , the fluid needs to be guided to the surface of the glass rod A through the slope 5 .

[0028] An anti-skid end 3 is provided on the upper portion of the installation sleeve 2 to increase the friction between the finger and the installation sleeve 2 and play an anti-skid role.

[0029] Embodiment 2:

[0030] like Figure 4 , Figure 5 As shown, on the basis of Example 1, the protective wall 4 in Example 1 is cancelled, and a baffle 6 is extended downward along the lower edge of the funnel 1, and the two sides of the baffle 6 are connected to the mounting sleeve 2.

[0031] like Figure 1 , Figure 6 As shown, when in use, the guide funnel C is installed on the glass rod A, and the glass rod A is tilted into the beaker B. The position of the guide funnel C on the glass rod A can be adjusted according to personal operating habits, the volume of the beaker B, and the physical and chemical properties of the added fluid.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
