DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0019] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0020] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0021] like Figure 1-3 The utility model provides an ultrasonic extractor, including a cavity 1, a cover 2 covering the opening of the cavity 1, a stirring rod 3 rotatably arranged inside the cover 2, and an ultrasonic generator 4 is arranged inside the cover 2, and a liquid storage box 5 and a filter screen 6 are installed inside the cavity 1 from bottom to top, and the liquid storage box 5 and the filter screen 6 are both detachably arranged in the cavity 1.

[0022] Place the liquid storage box and the filter in the cavity in turn, and put the cover on the cavity, then put the extracted medicine into the cavity, start the ultrasonic generator for oscillation separation, and start the stirring rod to stir the medicine evenly to improve the extraction effect and efficiency. After the extraction is completed, the filter and the liquid storage box can be taken out of the cavity in turn to facilitate the extraction of the extracted medicine liquid and the cleaning of the filter and the liquid storage box.

[0023] The cover body is provided with a motor, which controls the stirring rod to rotate and stir; the cover body is also provided with a feed port, and the medicine is put into the cavity through the feed port.

[0024] In one embodiment of the present solution, the cover body and the cavity body are connected by threads to form a detachable fit, and a sealing ring is installed at the connection between the cover body and the cavity body to ensure that the drug solution does not leak out.

[0025] Preferably, a mounting groove 7 is circumferentially provided at the opening of the cavity 1, and the inner side of the mounting groove 7 is provided with a conical surface. The filter screen 6 is mounted on a support frame 8, and the support frame 8 is provided with a mounting surface along the circumferential direction, and the mounting surface is a conical structure matching the mounting groove 7.

[0026] Specifically, by matching the conical surface between the mounting surface and the mounting groove, the support frame can be limited in the mounting groove by the deadweight of the support frame and the filter during the lowering process, and when the medicine is placed in the cavity, the stability of the support frame can be further increased by the medicine.

[0027] It is worth mentioning that due to the conical surface setting of the installation groove, there are no cleaning dead corners such as grooves at the installation groove, and the drug residue is usually accumulated on the upper surface of the filter screen, so dead-angle cleaning at the installation groove is particularly important.

[0028] Preferably, a plurality of counterweights 9 are arranged at intervals along the circumferential direction on the lower side of the support frame 8 .

[0029] Specifically, since the stirring rod and the ultrasonic generator will cause a certain degree of vibration to the drug when they are started, in order to avoid the filter mesh being vibrated during the drug vibration process, which in turn causes the filter mesh to shift, etc., a counterweight block is added to improve the stability of the support frame itself to ensure the stability of the filtration.

[0030] Preferably, a plurality of support blocks 10 are disposed on the side of the liquid storage box 5 , and a plurality of guide grooves 11 matching the support blocks 10 are disposed on the inner side of the cavity 1 , so that the support blocks 10 and the guide grooves 11 are movably matched.

[0031] Specifically, when installing the liquid storage box, align the support block with the position of the guide groove so that the support block falls along the guide groove, thereby positioning the installation direction of the liquid storage box, improving the accuracy of the installation position of the liquid storage box, and avoiding the liquid storage box from being offset during use, ensuring that the medicine flowing through the filter screen can accurately drip into the liquid storage box.

[0032] Preferably, a flaring structure 12 is provided at the opening of the liquid storage box 5 .

[0033] Specifically, the opening area of ​​the liquid storage box is increased by the expansion structure, so as to improve the stability of the liquid storage box in containing the liquid medicine and prevent the liquid medicine from dripping to the outside of the liquid storage box.

[0034] Preferably, there is a gap between the bottom of the cavity 1 and the bottom of the liquid storage box 5 .

[0035] Specifically, when the ultrasonic extractor is tilted or other circumstances cause the medicine liquid to drip to the outside of the liquid storage box, this part of the medicine liquid will gather at the bottom of the cavity, which will prevent the medicine liquid gathered at the bottom of the cavity from generating buoyancy on the liquid storage box, thereby causing the liquid storage box to be placed unstable. Therefore, a gap is set between the cavity and the liquid storage box so that the medicine liquid gathered at the bottom of the cavity will not directly contact the bottom of the liquid storage box, thereby ensuring the stable placement of the liquid storage box.

[0036] Preferably, a drain port 13 is provided at the bottom of the cavity 1 , and a plug 14 is detachably provided at the drain port 13 .

[0037] Specifically, the liquid discharge port is blocked by a plug, and when the liquid medicine at the bottom of the cavity needs to be discharged, the plug can be pulled out to conveniently discharge the liquid medicine at the bottom of the cavity.

[0038] Preferably, a push rod 15 is detachably provided at the liquid discharge port 13 , so that after the plug 14 is removed, the push rod 15 can lift the liquid storage box 5 from the liquid discharge port 13 .

[0039] Specifically, when the liquid storage box and the filter screen need to be disassembled, the plug is pulled out, and then the push rod is pushed upward from the discharge port so that the end of the push rod pushes the liquid storage box and the filter screen, so that the liquid storage box and the filter screen can be easily taken out of the cavity.

[0040] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
