[0002] The rotary evaporator is an evaporation instrument widely used in laboratories. It is suitable for reflux operation, rapid evaporation of large amounts of solvents, concentration of trace components, and reaction processes that require stirring. The rotary evaporator system can be sealed and decompressed to 400-600 mm Hg; the solvent in the distillation flask (rotary evaporation flask) is heated with a heating bath, and the heating temperature can be close to the boiling point of the solvent; it can also rotate at a speed of 50-160 rpm to form a thin film of the solvent and increase the evaporation area. In addition, under the action of an efficient cooler, the hot vapor can be quickly liquefied to accelerate the evaporation rate.

[0019] Figure 2 It is a schematic structural diagram of the crystal crushing spoon of the rotary evaporator bottle of the utility model in an upright state. DETAILED DESCRIPTION

[0020] The following is a more detailed description of the rotary evaporator crystal crushing spoon of the utility model in conjunction with the schematic diagram, which shows the preferred embodiment of the utility model. It should be understood that those skilled in the art can modify the utility model described herein and still achieve the beneficial effects of the utility model. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation to the utility model.

[0021] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0022] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a rotary evaporator crystal crushing spoon, comprising a spoon head 1, a spoon rod 2 and a spoon handle 3.

[0023] Specifically, the spoon head 1 is fixedly arranged at the end of the spoon rod 2, the spoon head 1 is arranged in a "Y" shape, and the notch of the spoon head 1 is used to crush crystals of different particle sizes.

[0024] The spoon rod 2 is located between the spoon head 1 and the spoon handle 3 , and the spoon rod 2 is used to connect the spoon head 1 and the spoon handle 3 .

[0025] The spoon handle 3 is installed on the end of the spoon rod 2 away from the spoon head 1 , and the spoon handle 3 is used for an operator to clamp and mash the spoon head 1 .

[0026] In this embodiment, after the crystals are added to the rotary evaporator, when the crystals need to be crushed, the spoon head 1 is placed on the surface of the crystals and pressed and moved. The crystals are crushed after being squeezed and slid. At the same time, larger particles of crystals are squeezed out along the "Y"-shaped notch. During the extrusion of the crystals, the crystals are scraped against the side walls of the "Y"-shaped notch and crushed. The above operation is repeated to crush the crystals in the rotary evaporator.

[0027] It should be noted that the spoon head 1 is arranged in a "Y" shape, and the width of its notch gradually increases along the length of the spoon head 1, so that crystals of different particle sizes can be scraped and crushed. In addition, with the large crushing surface of the spoon head, a comprehensive crushing operation of the crystals can be achieved.

[0028] Furthermore, the outer edge of the spoon head 1 is configured to be in an arc shape.

[0029] Specifically, the outer edge of the spoon head 1 is configured to be arc-shaped, which can effectively reduce the risk of the sharp part of the spoon head 1 causing damage to the operator, and also reduce the risk of the rotary evaporator flask being broken due to collision when the sharp part of the spoon head 1 is inserted into the rotary evaporator flask.

[0030] In a specific embodiment, the angle α between the spoon head 1 and the spoon stem 2 is 90°-130°. The angle α between the spoon head 1 and the spoon stem 2 can also be 100°, 110°, 120°, etc.

[0031] In addition, in order to reduce the occurrence of rust on the spoon head 1 and the spoon rod 2 due to moisture after use, the spoon head 1 and the spoon rod 2 are both made of stainless steel.

[0032] Furthermore, the spoon rod 2 is externally covered with a silicone protective sleeve 4, and the length of the spoon rod 2 is 45cm-50cm.

[0033] Specifically, when the crystals in the rotary evaporator are crushed, the spoon rod 2 is likely to collide with the mouth of the rotary evaporator. In order to reduce the risk of the rotary evaporator flask being broken due to the collision between the spoon rod 2 and the rotary evaporator, a silicone protective sleeve 4 is provided on the outside of the spoon rod 2 to have a certain buffering effect, thereby achieving the purpose of protecting the rotary evaporator.

[0034] Furthermore, the spoon handle 3 is sleeved on the end of the spoon rod 2 , and the outer diameter of the spoon handle 3 is greater than the outer diameter of the spoon rod 2 .

[0035] Specifically, since the spoon rod 2 is thin, it is not convenient for the operator to hold and fix it. Therefore, a spoon handle 3 is provided at the end of the spoon rod 2, and the outer diameter of the spoon handle 3 is larger than the outer diameter of the spoon rod 2, so that the operator can hold the spoon rod 2 conveniently and crush the crystals in the rotary evaporator through the spoon head 1.

[0036] In order to prevent the operator from being scalded by the heat conduction of the spoon rod 2 and the spoon handle 3, a heat insulation layer 5 is provided on the outer surface of the spoon handle 3. The heat insulation layer 5 has a heat insulation effect, reduces the heat transfer of the spoon handle 3 to the operator, and thus plays a role in protecting the operator.

[0037] Compared with the prior art, the utility model has at least the following beneficial effects:

[0038] The utility model can crush the crystals in the rotary evaporator bottle by pressing and moving the spoon head, and the "Y"-shaped notch of the spoon head can also be used to scrape the crystals, thereby speeding up the crushing operation of the crystals. The utility model has the characteristics of simple structure, convenient operation and good crushing effect.

[0039] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
