Microwave reaction cavity and microwave equipment using the same

Abstract

The present invention provides a microwave reaction chamber and a microwave device using the same. The advantages of the microwave reaction chamber are that it is not necessary to completely remove a device carrying a microwave reaction tank from a main body before taking out the microwave reaction tank, which facilitates operation for an operator and can prevent chemical reagents from harming the operator, thereby ensuring the operator's safety. The operator only needs to push or pull the end of a top cover close to the operator to open or close the microwave reaction chamber, which greatly shortens the operator's operating distance. Moreover, after the microwave reaction chamber is opened, the top cover is placed above the microwave reaction chamber and does not occupy space outside the microwave reaction chamber in the horizontal direction, thereby greatly increasing space utilization.

Description

Technical Field

[0001] The present invention relates to the field of microwave reaction equipment, in particular to a microwave reaction cavity and microwave equipment using the microwave reaction cavity. Background Art

[0002] Figure 1A This is a schematic diagram of the closed structure of an existing microwave reaction cavity. Figure 1A The microwave reaction chamber includes a main body 10. The microwave reaction tank (not shown in the drawings) is placed in the main body 10. An opening 12 is provided on the side of the main body 10, and a cover 11 is provided on the side of the main body 10 and covers the opening 12. Since the opening 12 is blocked by the cover 11, it is drawn with dotted lines in the drawings. When the microwave reaction tank needs to be taken out of the microwave reaction chamber, the cover 11 needs to be opened. There are two ways to open the cover 11. One way to open it is to open it in Figure 1A In the embodiment, a handle 111 is provided on the right side of the cover 11, and the handle 111 on the cover 11 is pulled to the left to open the cover 11 horizontally; another opening method is that the handle can be provided at the upper end of the cover 11, and when opening the cover, the handle needs to be pulled downward to open the cover. Figure 1A For the corresponding schematic diagram of opening the cover 11, please refer to Figure 1B .

[0003] A disadvantage of this type of microwave reaction chamber is that when taking out the microwave reaction tank, the microwave reaction tank needs to be lifted up in the vertical direction and then taken out, but the height of the main body is limited. Therefore, the device carrying the microwave reaction tank needs to be completely removed from the main body 10 before the microwave reaction tank is taken out. This will cause a lot of inconvenience to the operator and may cause chemical reagents to harm the operator.

[0004] In view of the above-mentioned shortcomings of the microwave reaction cavity, researchers have developed a new type of microwave reaction cavity.

[0005] Figure 1C This is a schematic diagram of an existing structure for closing a microwave reaction cavity. Figure 1CThe microwave reaction chamber includes a main body 10 and a cover 11. The sample can (not shown in the drawings) is placed in the main body 10. An opening 12 is provided at the top of the main body 10, and the cover 11 is provided at the top of the main body 10 and covers the opening 12. Since the opening 12 is blocked by the cover 11, it is drawn with dotted lines in the drawings. When the sample can needs to be taken out of the microwave reaction chamber, the cover 11 needs to be opened. The cover 11 is opened by pushing the handle 111 on the cover 11 so that the cover 11 moves horizontally around the rotating shaft 112, thereby opening the cover 11. This actuation of the cover 11 is similar to that of a pendulum valve. For a schematic diagram of the opening of the cover 11, please refer to Figure 1D .

[0006] Although this type of microwave reaction chamber can avoid the defect of having to completely remove the device carrying the microwave reaction tank from the main body before taking out the microwave reaction tank, it also has a disadvantage: after the cover 11 is opened, the cover 11 will occupy the space outside the microwave reaction chamber in the horizontal direction. When multiple microwave reaction chambers are stored in the same space, adjacent microwave reaction chambers need to be separated by a certain distance to facilitate opening the cover 11, which occupies more fixed horizontal space.

[0007] Figure 1E This is another existing schematic diagram of the structure of a microwave reaction chamber. Figure 1E The microwave reaction chamber includes a main body 10 and a cover 11. The sample can (not shown in the drawings) is placed in the main body 10. An opening 12 is provided at the top of the main body 10, and the cover 11 is provided at the top of the main body 10 and covers the opening 12. Since the opening 12 is blocked by the cover 11, it is drawn with dotted lines in the drawings. When the sample can needs to be taken out of the microwave reaction chamber, the cover 11 needs to be opened. The cover 11 is opened by pulling the handle 111 on the cover 11 in the vertical direction to lift the cover 11 in the vertical direction, thereby opening the cover 11. For a schematic diagram of opening the cover 11, please refer to Figure 1F .

[0008] Although this type of microwave reaction chamber can avoid the defect of having to completely remove the device carrying the microwave reaction tank from the main body before taking out the microwave reaction tank, it also has disadvantages: the height of the main body 10 is relatively high, and the size of the cover 11 is large. As the cover 11 is opened, the position of the handle 111 becomes higher and higher. This makes it difficult for the operator to pull the handle 111 vertically, and requires the use of other external objects to pull the handle 111, which brings a lot of inconvenience to the operation.

[0009] Therefore, there is an urgent need for a microwave reaction cavity that can overcome the above shortcomings. Summary of the Invention

[0033] The specific embodiments of the microwave reaction cavity provided by the present invention and the microwave equipment using the microwave reaction cavity are described in detail below with reference to the accompanying drawings.

[0034] Figure 2 This is a schematic structural diagram of the microwave reaction chamber in a closed state of the present invention. Figure 3 This is a schematic structural diagram of the microwave reaction chamber of the present invention in a semi-open state; Figure 4 This is a schematic structural diagram of the microwave reaction chamber of the present invention in an open state. Figure 5 is a partial cross-sectional view of an embodiment of a microwave reaction chamber of the present invention. Figure 6 This is another partial cross-sectional view of an embodiment of the microwave reaction chamber of the present invention. Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The microwave reaction chamber of the present invention includes a main body 20 and a top cover 21.

[0035] The main body 20 has a first cavity 200. Specifically, the main body 20 is hollow, forming the first cavity 200. A microwave reaction tank 30 for microwave reaction can be placed within the first cavity 200. Specifically, the bottom of the microwave reaction tank 30 contacts the bottom of the first cavity 200, and the top of the microwave reaction tank 30 faces the top of the first cavity 200.

[0036] The top of the main body 20 has an inclined portion 201. The orthographic projection area of the inclined portion 201, in a direction perpendicular to the top of the main body 20, is smaller than the orthographic projection area of the top of the main body 20. That is, the inclined portion 201 does not occupy the entire top of the main body 20, but only a portion of the top of the main body 20. For example, a portion of the top of the main body 20 may be tilted relative to a horizontal plane to form the inclined portion 201. Specifically, in this embodiment, one side of the top of the main body 20 is tilted toward a side of the main body 20 to form the inclined portion 201.

[0037] An opening 202 is provided in the inclined portion 201 to expose the first cavity 200. The opening 202 may expose the entire first cavity 200 or a portion thereof. For example, when the projection of the opening 202 in the vertical direction (such as the Y direction in the figure) coincides with the projection of the first cavity 200 in the vertical direction, the opening 202 exposes the entire first cavity 200. In this embodiment, however, the projection of the opening 202 in the vertical direction (such as the Y direction in the figure) does not coincide with the projection of the first cavity 200 in the vertical direction, and thus the opening 202 exposes a portion of the first cavity 200.

[0038] The top cover 21 is disposed at the top end of the main body 20. The top cover 21 has a second cavity 210 that is recessed away from the main body 20. The top cover 21 is movable between a first position and a second position. The first position refers to the position of the top cover 21 when it covers the opening 202, and the second position refers to the position of the top cover 21 when it completely does not cover the opening 202. Specifically, when the top cover 21 is in the first position, the microwave reaction cavity is closed, and when the top cover 21 is in the second position, the microwave reaction cavity is open. That is, when the microwave reaction cavity is closed, the top cover 21 covers the opening 201, sealing the main body 20. Removing the top cover 21 from the opening 202 opens the microwave reaction cavity. At this point, the opening 202 is no longer blocked by the top cover 21, exposing the interior of the first cavity 200. The microwave reaction tank 30 can then be placed in and out of the opening 202.

[0039] When the top cover 21 is in the first position, the top cover 21 covers the opening 202, and the first cavity 200 and the second cavity 210 form a microwave reaction cavity of a preset shape. In other words, the first cavity 200 and the second cavity 210 are complementary structures, and together they form a microwave reaction cavity of a preset shape. The preset shape includes, but is not limited to, a cuboid, a cube, or a cylinder. In other words, after the shape of the microwave reaction cavity is set, a cutting surface can be used to divide the microwave reaction cavity into two parts, one of which serves as the shape of the first cavity 200 and the other serves as the shape of the second cavity 210, so that when the top cover 21 covers the opening 202, the first cavity 200 and the second cavity 210 can form a microwave reaction cavity of the preset shape.

[0040] To ensure a sufficient and efficient microwave reaction, the microwave reaction chamber requires a specific shape. As described in the background art, existing microwave reaction chambers meet these specific shape requirements, but their top covers are poorly designed, making them inconvenient for operators. The microwave reaction chamber of the present invention, however, has a complementary structure with its first cavity 200 and second cavity 210. The opening 202 is angled, and the inclined portion 201 only occupies a portion of the top of the main body 20. This ensures that the microwave reaction chamber meets these specific shape requirements while facilitating access to the microwave reaction tank 30.

[0041] in, Figure 5 is a partial cross-sectional view of an embodiment of a microwave reaction chamber of the present invention. Figure 6 This is another partial cross-sectional view of an embodiment of the microwave reaction chamber of the present invention. Figure 5 and Figure 6 When the top cover 21 is in the first position, the edge of the second cavity 210 of the top cover 21 contacts the edge of the opening 202, so that the first cavity 200 and the second cavity 210 form a microwave reaction cavity of a preset shape. Figure 5 In the embodiment, the cross-sectional shape of the first cavity 200 formed by cutting through the plane where the opening 202 is located overlaps with the shape of the opening 202, and the projection of the second cavity 210 on the plane where the opening 202 is located overlaps with the shape of the opening 202. That is, the first cavity 200 and the second cavity 210 can form a regularly shaped microwave reaction cavity. For example, in this embodiment, the preset shape of the microwave reaction cavity is a rectangular parallelepiped, the second cavity 210 is the upper left corner of the rectangular parallelepiped, and the first cavity 200 is the remaining portion of the rectangular parallelepiped. Of course, in other embodiments of the present invention, the microwave containing cavity can also be divided into other ways to form the first cavity 200 and the second cavity 210. Furthermore, in this embodiment, the outer edge of the opening 202 has a first contact member 204, and the outer edge of the second cavity 210 has a second contact member 211. That is, the first contact member 204 surrounds the outer edge of the opening 202, and the second contact member 211 surrounds the outer edge of the second cavity 210. When the top cover 21 covers the opening 202, the first contact member 204 contacts the second contact member 211. The first contact member 204 and the second contact member 211 increase the contact area between the top cover 21 and the main body 20, thereby facilitating the fixing of the top cover 21.

[0042] In this embodiment, the top of the main body 20 further includes a horizontal portion 203. The horizontal portion 203 and the inclined portion 201 are sequentially arranged along the direction from the first position to the second position of the top cover 21. This has the advantage that, given a specific opening size, the opening 202 can be brought closer to the operator, thereby facilitating operation.

[0043] In the present invention, the microwave reaction chamber can be closed by covering the opening 202 with the top cover 21, and can be opened by removing the top cover 21 from the opening 202. A person skilled in the art can obtain methods for moving the top cover 21 from the prior art, for example, by using a mechanical structure to assist or directly moving the top cover 21.

[0044] In this embodiment, a structure for moving the top cover 21 is described. The details are as follows:

[0045] The microwave reaction chamber further includes a supporting mechanism, and the supporting mechanism includes at least one supporting unit 22 .

[0046] The support unit 22 includes a first support rod 220 and a second support rod 221. The first support rod 220 has two ends rotatably connected to the side walls of the main body 20 and the top cover 21, respectively. The second support rod 221 has two ends rotatably connected to the side walls of the main body 20 and the top cover 21, respectively. Specifically, in this embodiment, the first support rod 220 has two ends rotatably connected to the side walls of the main body 20 and the top cover 21, respectively, via a rotating shaft (not shown in the drawings). The second support rod 221 also has two ends rotatably connected to the side walls of the main body 20 and the top cover 21, respectively, via a rotating shaft (not shown in the drawings). In other words, the first support rod 220 is rotatable relative to the side walls of the main body 20 and the top cover 21, while the second support rod 221 is rotatable relative to the side walls of the main body 20 and the top cover 21. When the top cover 21 moves between the first position and the second position, the first support rod 220 and the second support rod 221 support the top cover 21.

[0047] The first support rod 220 and the second support rod 221 may be of equal length or of different lengths, as long as the microwave reaction cavity of the present invention can be opened and closed.

[0048] Preferably, the support structure includes two support units 22, which are symmetrically arranged on either side of the main body 20. That is, the first support rods 220 of the two support units 22 are symmetrically arranged, and the second support rods 221 of the two support units 22 are symmetrically arranged. This has the advantage of enabling the support mechanism to more stably support the top cover 21.

[0049] In this embodiment, the method of opening and closing the microwave reaction chamber is described in detail as follows:

[0050] See also Figure 2 The top cover 21 is in the first position as the initial state of the top cover 21. The operator lifts and pushes the top cover 21 toward the horizontal portion 203. Under the force of the operator's upward movement, the top cover 21 moves toward the horizontal portion 203, driving the first support rod 220 and the second support rod 221 to rotate with it. Since the distance between the connection point between the first support rod 220 and the top cover 21 and the connection point between the first support rod 220 and the side wall of the main body 20 remains unchanged, and the distance between the connection point between the second support rod 221 and the top cover 21 and the connection point between the second support rod 221 and the side wall of the main body 20 remains unchanged, when the top cover 21 is pushed, it is supported by the first support rod 220 and the second support rod 221 and is released from contact with the edge of the opening 201. At this point, the top cover 21 is not in contact with the top end of the main body 20, but rather maintains a distance therebetween.

[0051] See also Figure 3 , continue to push the top cover 21, the top cover 21 moves toward the horizontal portion 203, at this time, the first support rod 220 and the second support rod 221 can support the top cover 21, the top cover 21 and the top end of the main body 20 are still not in contact, but there is a distance between them.

[0052] See also Figure 4 , push the top cover 21 to move it to the second position. At this time, the top cover 21 is placed on the horizontal portion 203, and the opening 202 is completely exposed, thereby opening the microwave reaction cavity.

[0053] To close the microwave reaction chamber, the top cover 21 is pulled to move in the reverse direction, and the movement process is not described again.

[0054] In this embodiment, the operator only needs to lift and push the end of the top cover 21 closer to the operator to open or close the microwave reaction chamber, which greatly shortens the operator's operating distance. Moreover, after the microwave reaction chamber is opened, the top cover 21 is placed above the microwave reaction chamber and does not occupy the space outside the microwave reaction chamber in the horizontal direction, which can greatly increase space utilization.

[0055] In this embodiment, the horizontal portion 203 can support the top cover 21 . In other embodiments of the present invention, other structures may also be used to support the top cover 21 , which is not limited herein.

[0056] In this embodiment, the support mechanism further includes a first fixing member 23 and a second fixing member 24. The first fixing member 23 is fixed to the top cover 21, and the second fixing member 24 is fixed to the side wall of the main body 20. The two ends of the first support rod 220 are rotatably connected to the first fixing member 23 and the second fixing member 24, respectively, and the two ends of the second support rod 221 are rotatably connected to the first fixing member 23 and the second fixing member 24, respectively. In other words, the two ends of the first support rod 220 are fixed to the top cover 21 and the side wall of the main body 20 through the first fixing member 23 and the second fixing member 24, and the two ends of the second support rod 221 are fixed to the top cover 21 and the side wall of the main body 20 through the first fixing member 23 and the second fixing member 24.

[0057] Furthermore, the first fixing member 23 is concave, and one end of the first support rod 220 and one end of the second support rod 221 are respectively rotatably connected to the same side wall of the concave, and the other side wall of the concave is connected to the top cover 21; the second fixing member 24 is concave, and one end of the first support rod 220 and one end of the second support rod 221 are respectively rotatably connected to the same side wall of the concave, and the other side wall of the concave is connected to the side wall of the main body 20.

[0058] Furthermore, the distance from the connection between the first support rod 220 and the top cover 21 to the connection between the first support rod 220 and the side wall of the main body 20 is greater than the distance from the connection between the first support rod 220 and the side wall of the main body 20 to the top end of the main body 20; the distance from the connection between the second support rod 221 and the top cover 21 to the connection between the second support rod 221 and the side wall of the main body 20 is greater than the distance from the connection between the second support rod 221 and the side wall of the main body 20 to the top end of the main body 20, thereby ensuring that the top cover 21 can be detached from the top end of the main body 20 during the movement of the top cover 21, thereby facilitating the movement of the top cover 21.

[0059] The present invention also provides a microwave device using the microwave reaction cavity, which includes but is not limited to microwave digesters, microwave extractors, microwave synthesizers, and other devices well known to those skilled in the art.

[0060] The above description is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
