Detailed Embodiments

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application. It should be noted that, without conflict, the embodiments and features in the embodiments of the present application may be arbitrarily combined with each other.

[0032] When performing chromatographic analysis, it is usually necessary to place the reagent in an oven to maintain temperature stability during the sample analysis process. In the traditional oven design, there are the following two connection methods between the door and the oven body: The first method is to use a hinge connection to enable the door to rotate to one side to complete the door opening action; the second method is to use a magnetic attraction connection. At this time, the door and the oven body are detachable. However, in the hinge connection method, it does not support the quick disassembly between the door and the oven body. At the same time, when multiple ovens are arranged side by side, the doors cannot be opened to 180° simultaneously, which is not convenient for cleaning or maintaining the inside of the oven. In the magnetic attraction connection method, when multiple doors are disassembled simultaneously, it will cause chaos at the work site. Different staff members have different preferences for the operation of the detachable or hinged door connection method, and the connection method between the door and the oven body in the prior art cannot meet the operation preferences of different personnel.

[0033] Based on this, an exemplary embodiment of the present application provides a detachable structure for the oven door and an oven. The detachable structure for the oven door includes a first connection structure provided on the upper part of the oven body, a second connection structure provided on the upper part of the door, and a third connection structure provided on the lower part of the oven body. The first connection structure and the second connection structure adopt a coupling method, so that after the oven body and the door are rotated by a preset angle, the first connection structure can be separated from the second connection structure by pulling, thereby realizing the separation of the upper part of the door from the oven body; then the door is lifted at an angle inclined upward to separate the lower part of the door from the third connection structure, thereby realizing the quick separation between the door and the oven body. In the present application, the oven body and the door can be opened and closed either by a hinge method or by a quick disassembly method to separate the oven body and the door, so as to meet the various operation preferences of different staff members.

[0034] An exemplary embodiment of the present application provides a detachable structure for the oven door, such as Figures 1 to 3As shown, the column oven includes a column oven body 100 and a column oven door body 200. The detachable structure includes: a first connection structure 300 disposed on the upper part of the column oven body 100; a second connection structure 400 disposed on the upper part of the door body 200; and a third connection structure 500 disposed on the lower part of the column oven body 100. Among them, the first connection structure 300 and the second connection structure 400 adopt a coupling method, so that between the column oven body 100 and the door body 200, they can not only be opened and closed by means of hinge, but also, after the door body 200 is rotated by a preset angle, the first connection structure 300 and the second connection structure 400 are separated by a pulling method, so as to realize the separation of the upper part of the door body 200 from the column oven body 100; then the door body 200 is lifted at an angle inclined upward to separate the lower part of the door body 200 from the third connection structure 500, so as to realize the rapid separation between the door body 200 and the column oven body 100. Between the column oven body 100 and the door body 200, they can be opened and closed by means of hinge, or the column oven body 100 and the door body 200 can be separated by a rapid disassembly method to meet the various operation preferences of different staff.

[0035] As Figure 3 and 4 shown, the first connection structure 300 includes a first connecting member 301 disposed in the column oven body 100, and an elastic element 302 and a ball 303 which are sequentially and movably disposed in the first connecting member 301 from top to bottom. Preferably, the elastic element 302 is a spring. Under the action of an external force, the ball 303 can move up and down in the first connecting member 301, but will not fall off from the first connecting member 301.

[0036] In one embodiment, as Figure 3 , Figure 5 , Figure 6 shown, the second connection structure 400 includes a mounting portion 401 disposed in the door body 200; a connecting portion 402 connecting the mounting portion 401, and a connecting groove 404 is formed on the connecting portion 402. The connecting groove 404 is preferably an arc-shaped groove to facilitate the rolling of the ball 303; an avoidance portion 403 connected to the connecting portion 402, the top of the avoidance portion 403 is an arc surface, and an avoidance groove 405 is formed on the avoidance portion 403. The avoidance groove 405 is preferably arranged along the arc surface, and one end of the avoidance groove 405 is close to the mounting groove. When the column oven body 100 and the door body 200 are hinged through the first connection structure 300, the second connection structure 400, and the third connection structure 500, the ball 303 is movably disposed in the connecting groove 404. When the door body 200 is rotated, the ball 303 acts as a hinge to realize the relative rotation between the door body 200 and the column oven body 100.

[0037] The third connection structure 500 is a connecting pin. When the door body 200 rotates a preset angle relative to the column oven cabinet 100, for example, to facilitate pulling out the door body 200, the door body 200 can be rotated 90° relative to the column oven cabinet 100. Of course, it can also be rotated by any other angle. Then, the door body 200 is pulled out along the direction extending the width of the door body 200. At this time, the ball 303 disengages from the installation groove and disengages from the second connection structure 400 along the avoidance groove 405, realizing the separation between the upper part of the door body 200 and the column oven cabinet 100.

[0038] In one embodiment, a receiving chamber for receiving the third connection structure 500 is provided at the bottom of the door body 200, and the volume of the receiving chamber is larger than the volume of the third connection structure 500. In this way, when pulling out the door body 200, the receiving chamber can provide a space for the third connection structure 500 to move relative to the receiving chamber.

[0039] After the upper part of the door body 200 is separated from the column oven cabinet 100, the door body 200 can be separated from the third connection structure 500, thereby realizing the complete separation between the door body 200 and the column oven cabinet 100.

[0040] In one embodiment, mounting holes for mounting the first connection structure and the third connection structure 500 are provided on both sides of the column oven cabinet 100, and mounting holes for mounting the second connection structure 400 are provided on both sides of the door body 200. In this way, according to different operation requirements, the door body 200 can be connected to one side of the column oven cabinet 100 or the other side of the column oven cabinet 100 to meet different requirements, enabling the door body 200 to be opened in both directions.

[0041] In one embodiment, a plurality of magnetic components are distributed on the door body 200 to achieve a tight fit between the door body 200 and the column oven cabinet 100. These magnetic components can be evenly distributed on the edge of the door body 200 to ensure the sealing performance between the door body 200 and the column oven cabinet 100 when the door body 200 is closed. In this way, not only can the stability of the temperature inside the column oven be improved, but also the influence of external environmental factors on the temperature inside the column oven can be prevented, thereby ensuring the accuracy of chromatographic analysis.

[0042] An exemplary embodiment of the present application provides a column oven, which includes a detachable structure for the column oven door body. The column oven cabinet 100 and the door body 200 are rotatably or detachably arranged through the detachable structure for the column oven door body. In this way, the column oven cabinet 100 and the door body 200 can be opened and closed by means of hinging, or the column oven cabinet 100 and the door body 200 can be separated by means of quick disassembly to meet the various operation preferences of different staff.
