[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the described embodiments are only a part of the embodiments of the present application, rather than all embodiments. The specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0027] It should be further noted that the drawings and embodiments of the present utility model mainly describe the concept of the present utility model. On the basis of this concept, the specific forms and settings of some connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems, control systems, etc. may not be completely described. However, on the premise that those skilled in the art understand the concept of the present utility model, those skilled in the art can implement the above specific forms and settings in a well-known manner.

[0028] When an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0029] The orientation terms "inside" and "outside" refer to the inside and outside of the contour of each component itself. The terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0030] For the convenience of description, spatial relative terms such as "above", "over", "on the upper surface", "above-mentioned", etc. can be used here to describe the spatial positional relationship between a device or feature shown in the drawings and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the drawings of the device.

Thus, the exemplary term "above" can include both the orientation of "above" and "below". The device can also be positioned in other different ways, and corresponding interpretations should be made for the spatial relative descriptions used here.

[0031] The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, the meaning of "a plurality" is two or more, and the meaning of "several" is one or more, unless otherwise specifically defined.

[0032] The top-illuminating quartz light guide column and the photoreaction device provided by the present utility model will be described hereinafter.

[0033] As Figures 1 to 4 shown, a first embodiment of the present utility model provides a top-illuminating quartz light guide column, which includes a quartz light guide column body 10. The quartz light guide column body 10 is a columnar structure, and its column surface is a smooth curved surface, and both ends are smooth flat surfaces or curved surfaces.

[0034] Compared with the prior art, the top-illuminating quartz light guide column provided in this embodiment, by using the quartz light guide column body 10 made of quartz material, not only has a certain structural strength, but also can be directly in contact with the reaction solution. This makes the light guiding part structure relatively simple. Only one quartz light guide column is needed to complete light guiding, and the light source and the reaction part are separated. Moreover, since the quartz light guide column body 10 is a columnar structure, and its column surface is a smooth curved surface, and both ends are smooth flat surfaces or curved surfaces, most of the light can be introduced into the reaction area, and the light utilization rate is relatively high.

[0035] In some specific embodiments, the quartz light guide column body 10 is made of high-transmission quartz material; one end of the quartz light guide column body 10 is a flat head structure or a round head structure to cooperate with the light source and better allow light to enter.

[0036] Based on the same inventive concept, as Figure 1 and Figure 2 shown, a second embodiment of the present utility model provides a photoreaction device, which includes a reaction vessel 20, a sealing plug assembly 30, a top-illuminating quartz light guide column, and a light source assembly 40. The reaction vessel 20 is provided with a light inlet; the sealing plug assembly 30 is sealingly connected to the light inlet; the top-illuminating quartz light guide column is inserted through the sealing plug assembly 30, and one end is located inside the reaction vessel 20 and the other end is located outside the reaction vessel 20; the light source assembly 40 is connected to or in contact with the end of the top-illuminating quartz light guide column located outside the reaction vessel 20, so as to introduce light into the reaction vessel 20 through the top-illuminating quartz light guide column.

[0037] Compared with the prior art, the photoreaction device provided in this embodiment, by guiding light through the top-illuminating quartz light guide column, can make the structure of the whole device relatively simple. Only one quartz light guide column is needed to complete light guiding, and the light source and the reaction part are separated, and a relatively high light utilization rate can be achieved.

[0038] In some specific embodiments, the sealing plug assembly 30 includes a plug body 31, a threaded sleeve 32, and a sealing ring 33. The lower part of the outer side of the plug body 31 is in sealing fit with the light inlet of the reaction vessel 20, and the upper part of the outer side is provided with an external thread. The plug body 31 is provided with a first through hole for the top-illuminating quartz light guide column to pass through; the threaded sleeve 32 is provided with an internal thread that matches the external thread and a second through hole for the top-illuminating quartz light guide column to pass through; the sealing ring 33 is arranged between the plug body 31 and the threaded sleeve 32, and is deformed under the extrusion of the threaded structures of the plug body 31 and the threaded sleeve 32 to seal the top-illuminating quartz light guide column and prevent leakage channels from being generated between the plug body 31 and the threaded sleeve 32 and the top-illuminating quartz light guide column. Moreover, with this structure, when the threaded sleeve 32 is loosened, the up-and-down movement of the top-illuminating quartz light guide column can be facilitated, so as to adjust the position of the lower end of the top-illuminating quartz light guide column and thus adjust the irradiation height.

[0039] Further, one end of the plug body 31 provided with the external thread is also provided with a sealing ring bayonet for accommodating the sealing ring 33, thereby improving the sealing performance of the sealing ring 33; the light inlet of the reaction vessel 20 is provided with a polytetrafluoroethylene ground joint to facilitate sealing cooperation with the plug body 31.

[0040] In some specific embodiments, a fixed sleeve 41 is provided on the light source assembly 40, and the photochemical reaction device further includes an adapter sleeve 50. The adapter sleeve 50 is sleeved on the top-illuminating quartz light guide column and inserted into the fixed sleeve 41. By providing the adapter sleeve 50, the light source assembly 40 can be stably connected to the top-illuminating quartz light guide column, and the surface of the top-illuminating quartz light guide column can be prevented from being scratched. By adjusting the length and number of the adapter sleeves 50, the coverage degree of the top-illuminating quartz light guide column can be changed, that is, the adapter sleeve 50 can be directly abutted against the threaded sleeve 32 to completely cover the entire quartz light guide column body 10, or the adapter sleeve 50 can be made not to contact the threaded sleeve 32 so that the middle part of the quartz light guide column body 10 is exposed.

[0041] Further, a fastening screw 42 is provided on the fixed sleeve 41. The fastening screw 42 is threaded through the fixed sleeve 41 and used to abut against the adapter sleeve 50 to fix the adapter sleeve 50 and the fixed sleeve 41 to ensure the stability of the connection.

[0042] Specifically, the reaction vessel 20 includes containers made of glass, quartz, steel, copper, aluminum, etc., such as flasks, test tubes, pressure tanks, or photochemical reaction kettles, which can be used for photochemical reactions.
