Description

Technical Field

[0001] The utility model relates to the technical field of extraction equipment, in particular to an ultrasonic extraction bottle. Background Art

[0002] Ultrasonic extraction utilizes the strong cavitation effect, mechanical vibration, disturbance effect, high acceleration, emulsification, diffusion, crushing and stirring effects produced by ultrasonic radiation pressure to increase the frequency and speed of molecular movement of substances and increase the penetration of solvents, thereby accelerating the entry of target ingredients into the solvent and promoting the extraction process.

[0003] During the extraction process, the extracting liquid is mixed with the powder to be extracted, and the large particles in the powder are also mixed in the solution, which results in the need to filter the solution after extraction to remove particles that do not meet the size requirements for subsequent instrumental analysis experiments. Based on this, people set an inner tank in the extraction bottle, put the extracting liquid in the extraction bottle, put the powder to be extracted in the inner tank, and at the same time, set a filter membrane on the inner tank to filter the large-sized particles through the filter membrane, so that the solution after extraction can be directly used for instrumental analysis experiments.

[0004] However, due to the thickness of the filter membrane and the characteristics of the soft material, the existing filter membrane is integrated with the inner liner. After each extraction, the inner liner and the filter membrane need to be replaced at the same time, which is costly. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to propose an ultrasonic extraction bottle for solving the problem that the filter membrane and the inner liner are integrally arranged in the prior art, resulting in the need to replace the inner liner and the filter membrane at the same time.

The inner bottle assembly includes: an inner tube having a through hole, and the through hole runs through the upper and lower ends of the inner tube; a fixed tube, which is sleeved on the lower end of the inner tube so that the filter membrane is stuck between the fixed tube and the inner tube and blocks the through hole.

[0009] Furthermore, the filter membrane has an initial state and a snap-in state; in the initial state, the filter membrane is planar; in the snap-in state, the filter membrane includes a planar filter area and an annular snap-in area, the filter area is at the lower end of the inner tube, and the snap-in area is between the outer wall of the inner tube and the inner wall of the fixed tube.

[0010] Furthermore, the fixing tube and the inner tube are interference fit.

[0011] Furthermore, the liquid level of the extraction liquid is higher than or lower than the highest height of the fixed tube.

[0012] Furthermore, the upper end of the outer bottle has a bottle mouth;

[0013] A first hanging portion is provided at the upper end of the inner tube, and the outer diameter of the first hanging portion is greater than the inner diameter of the bottle mouth, so that the inner tube can be hung in the outer bottle.

[0014] Furthermore, a second hanging portion is provided at the upper end of the fixing tube, the second hanging portion is hung at the bottle mouth, and the first hanging portion is hung on the second hanging portion.

[0015] Furthermore, an external thread is provided on the outer wall of the bottle mouth;

[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0029] Please refer to Figure 1-Figure 2 The utility model discloses an ultrasonic extraction bottle, comprising:

[0030] The outer bottle 100 is used to contain the extract;

[0031] The inner bottle assembly is arranged in the outer bottle 100 and is used to hold the powder to be extracted. The inner bottle assembly includes: an inner tube 300, which has a through hole, and the through hole runs through the upper and lower ends of the inner tube 300; a fixed tube 400, which is sleeved on the lower end of the inner tube 300, so that the filter membrane 500 is stuck between the fixed tube 400 and the inner tube 300 and blocks the through hole.

[0032] Specifically, the inner bottle assembly of the present application includes an inner tube 300 and a fixed tube 400. The fixed tube 400 is sleeved on the inner tube 300, and then the filter membrane 500 is inserted between the fixed tube 400 and the inner tube 300 to block the lower end of the inner tube 300, thereby realizing a detachable connection of the filter membrane 500. After the extraction is completed, it is only necessary to remove the fixed tube 400 to separate the fixed tube 400 from the inner tube 300, and the filter membrane 500 can be separated. A new filter membrane 500 is taken out and sleeved on the fixed tube 400, and the new filter membrane 500 is inserted between the fixed tube 400 and the inner tube 300, so that the filter membrane 500 can be replaced alone, without having to replace the inner tube 300 or the fixed tube 400 at the same time, and the cost is lower.

[0033] During the extraction process, the extract passes through the filter membrane 500, enters the inner tube 300 and is mixed with the powder to be extracted for extraction. The mixed solution then passes through the filter membrane 500 and returns to the extraction bottle. When passing through the filter membrane 500, the filter membrane 500 filters the large-sized particles in the solution, so that there are no large-sized particles in the solution after extraction, so as to facilitate direct instrumental analysis experiments on the extracted solution.

[0034] Furthermore, the filter membrane 500 has an initial state and a snap-in state; in the initial state, the filter membrane 500 is planar; in the snap-in state, the filter membrane 500 includes a planar filter area and an annular snap-in area, the filter area is located at the lower end of the inner tube 300, and the snap-in area is located between the outer wall of the inner tube 300 and the inner wall of the fixed tube 400.

[0035] Specifically, the area of ​​the filter membrane 500 is larger than the cross-sectional area of ​​the lower end of the inner tube 300. When installing the filter membrane 500, the filter membrane 500 is first placed flat on the upper end of the fixed tube 400 or the lower end of the inner tube 300, and then the fixed tube 400 is gradually pushed upward from the lower end of the inner tube 300. During the pushing process, a portion of the filter membrane 500 (the filtering area, i.e., the central area of ​​the filter membrane 500) stays in place and blocks the lower end surface of the inner tube 300, and another portion of the filter membrane 500 (the insertion area, and the annular edge area of ​​the filter membrane 500) is gradually inserted between the fixed tube 400 and the inner tube 300 as the fixed tube 400 is pushed, thereby finally achieving the fixed installation of the filter membrane 500.

[0036] Furthermore, the fixing tube 400 and the inner tube 300 are interference fit.

[0037] The fixing tube 400 and the inner tube 300 are interference fit, so that the filter membrane 500 can be inserted into the fixing tube 400 and the inner tube 300 and remain fixed.

[0038] Furthermore, the liquid level of the extraction liquid is higher than or lower than the highest height of the fixed tube 400 .

[0039] It should be noted that the inserted portion of the filter membrane 500 has certain wrinkles. Moreover, although the fixed tube 400 and the inner tube 300 are interference fit, the two cannot fit completely together, and there is still a certain gap between the two tubes. If the solution flows out from the gap, it will flow in. The wrinkled filter membrane 500 at this location cannot effectively filter the solution.

[0040] Based on this, the present application sets the maximum height of the fixed tube 400 to be greater than the liquid level of the extraction liquid, so that the extraction liquid will not pass through the gap between the fixed tube 400 and the inner tube 300 and enter the inner tube 300, and the solution mixed with the powder will not pass through the gap between the two and flow into the extraction bottle, so as to ensure that all solutions pass through the filtration area and ensure its filtration effect.

[0041] Furthermore, the upper end of the outer bottle 100 has a bottle mouth;

[0042] A first hanging portion is disposed at the upper end of the inner tube 300 , and an outer diameter of the first hanging portion is greater than an inner diameter of the bottle mouth, so that the inner tube 300 can be hung in the outer bottle 100 .

[0043] Furthermore, a second hanging portion is provided at the upper end of the fixing tube 400 , the second hanging portion is hung at the bottle mouth, and the first hanging portion is hung on the second hanging portion.

[0044] Furthermore, an external thread is provided on the outer wall of the bottle mouth;

[0045] The bottle cap 200 is also included. The inner wall of the bottle cap 200 is provided with an internal thread, and the internal thread can be engaged with the external thread.

[0046] Furthermore, a sealing gasket is provided between the bottle cap 200 and the first hanging portion, wherein the sealing gasket is used to seal the bottle mouth.

[0047] Place the first hanging part against the second hanging part, and place the second hanging part against the bottle mouth to install the inner tube 300 and the fixed tube 400, then rotate the bottle cap 200 to pre-tighten the inner tube 300, the fixed tube 400 and the outer bottle 100 to quickly assemble the outer bottle 100 and the inner bottle assembly.

[0048] The first hanging part and the second hanging part not only play the role of hanging the inner tube 300 and the fixing part, but also play the role of positioning the fixing tube 400 during the installation of the filter membrane 500 to prevent the fixing tube 400 from slipping out from the upper end of the inner tube 300.

[0049] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0050] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0051] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" 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 the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
