[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] See Figure 1 This utility model provides a detachable constant temperature jacket device for ultrasonic dispersion. The device includes an inner beaker 1, an outer beaker 2, an inner beaker lid 3 and an outer beaker lid 11, a drain port 8, a piston 7 and a circulating inlet / outlet 14, etc.

[0035] The inner beaker 1 is used to hold the sample. In one embodiment, the inner beaker has a capacity of 200 ml, a height of 10 cm, an outer diameter of 75 mm, and an inner diameter of 71 mm. It is preferably made of high borosilicate glass. An inner beaker lid 3 is provided on the inner beaker. The lower surface of the lid has an annular flange 4 to secure the lid to the inner beaker and prevent it from moving. The lid has two through holes, typically a central through hole and an eccentric through hole, used to house the amplitude transformer and temperature probe, respectively. The diameter of the central through hole is slightly larger than the outer diameter of the amplitude transformer at its maximum insertion depth, and the diameter of the eccentric through hole is slightly larger than the outer diameter of the temperature probe. In one embodiment, the diameter of the central through hole 5 is 2 cm, and the diameter of the eccentric through hole 6 is 7 mm. The lid is preferably made of polytetrafluoroethylene (PTFE), which is corrosion-resistant and not easily broken.

[0036] The outer beaker 2 is fitted outside the inner beaker 1, with a lower height, forming a jacket between them for the flow of cooling medium. In the aforementioned jacketed beaker for ultrasonic dispersion, the height of the outer beaker is approximately half that of the inner beaker. For example, for an inner beaker with a capacity of 200 ml, the height of the outer beaker can be 1.2-1.3 times the height of the 100 ml liquid level in the inner beaker. For instance, in one embodiment, the outer beaker 2 has a height of 5.5 cm (compared to 4.5 cm for the 100 ml liquid level in the inner beaker), an inner diameter of 131 mm, and an outer diameter of 135 mm. The preferred material is high borosilicate glass.

[0037] The outer beaker 2 has an annular positioning boss 9 at the bottom center, the size of which matches the outer diameter of the inner beaker, for example, designed so that the inner beaker 1 can be inserted just right. Rubber, such as an annular rubber strip 10, is preferably embedded on both sides of the bottom of the annular positioning boss 9 to increase friction with the inner beaker, facilitating fixation and protection of the inner beaker. For example, in the above embodiment, the annular positioning boss 9 has an inner diameter of 75 mm, an outer diameter of 80 mm, and a height of 1 / 7 to 1 / 8 of the height of the outer beaker. It is made of high borosilicate glass and has a 2.5 mm diameter silicone rubber strip embedded in it, with a semi-circular cross-section.

[0038] The outer beaker has a drain port 8 on its side, and a piston 7 is provided in the middle of the drain port pipe. For example, a dispensing funnel-type piston design is used in the middle of the drain port pipe to facilitate water discharge. In one embodiment, the drain port 8 has a diameter of 8 mm and a length of 5 cm, and the pipe axis is inclined downward at 5° to the horizontal plane, and is equipped with a medical-grade dispensing silicone piston 7.

[0039] There is a certain distance between the annular positioning boss in the middle of the outer beaker and the inner wall of the outer beaker, which facilitates the addition of ice during the ice bath. For example, in the above embodiment of the jacketed beaker for ultrasonic dispersion, the distance between the annular positioning boss and the inner wall of the outer beaker is 2.8 cm. Circulation inlet and outlet ports 14 are provided on both sides of the outer beaker at higher and lower positions, respectively, for the circulation of the cooling medium. The pipe axis is parallel to the horizontal plane and can be used for cooling medium circulation when the ice bath is not used; when condensation is not used, it is plugged by a plunger. In one embodiment, the pipe diameter at the connection between the inlet / outlet port 14 and the outer beaker is 10 mm, and the outlet diameter is 7 mm. The pipe axis is parallel to the horizontal plane and is equipped with a plunger.

[0040] An outer beaker lid 11, preferably made of polytetrafluoroethylene (PTFE), is provided on the outer beaker, with a central hole having a diameter equal to the outer diameter of the inner beaker. In the above embodiment, the diameter of this central hole is, for example, 75 mm, to accommodate the inner beaker. The outer beaker lid has a pull handle 12 for easy lifting of the lid to add ice. In an exemplary embodiment, the pull handle on the lid can be located on both sides of the lid, configured as a curved tube with a height of 2.5-3 mm. A small lid 13 can be provided at the central central hole of the outer beaker lid. The small lid can be composed of a PTFE lid body larger than the central hole and a cylindrical handle. The lower surface has an annular flange with a diameter equal to the diameter of the central hole to secure the outer beaker lid, and the upper handle facilitates lifting the lid.

[0041] When using the ice bath system, plug both inlet and outlet ports with plungers. Insert the inner beaker into the annular positioning boss, pour in 100 ml of the solution to be treated, and then cover it with the lid. Insert the amplitude transformer through the central through-hole to a position 1-1.5 cm from the liquid surface, and insert the temperature probe through the eccentric through-hole. Pour ice water into the outer beaker until it is level with the liquid surface in the inner beaker. When the temperature exceeds the set value, open the drain port to release the cooling medium, and lift the outer beaker lid with the handle. Add ice cubes through the gap between the inner and outer beakers to lower the temperature. After the experiment, the inner beaker can be disassembled for further processing, and the outer beaker can be cleaned of any residue. After cleaning, the small lid can be used to secure the round hole in the outer beaker lid to prevent dust accumulation inside the lid after prolonged storage. When using the condensation system, close the drain port for the ice bath, remove the plungers from both circulation inlet and outlet ports, and connect water pipes to allow the cooling medium to circulate inside the outer beaker.

[0042] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.

[0043] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
