Description

Technical Field

[0001] This utility model relates to the technical field of photochemical experimental equipment, and in particular to a photochemical reaction device that is easy to operate. Background Technology

[0002] Photochemical reactions refer to chemical reaction processes that occur under the illumination of an external light source. They are reactions initiated by the absorption of photons by molecules of a substance. However, when demonstrating in the classroom, due to environmental limitations, it is not possible to use standard instruments that correspond one-to-one to conduct photochemical reaction experiments. The space is also not large enough, which is very inconvenient. Moreover, the types and directions of light are generally not well demonstrated. Utility Model Content

[0003] This invention aims to overcome the shortcomings of existing experimental instruments that are too complex to adapt to the teaching environment and lack clarity regarding changes in experimental conditions. It provides a simpler, more user-friendly photochemical reaction device that is adaptable to the teaching environment and enhances the understanding of changes in experimental conditions.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A user-friendly photochemical reaction apparatus includes a multi-necked flask, a glass spring tube, a peristaltic pump, a raw material cup, a flask rack, a baffle frame, and an arc-shaped lamp top. The multi-necked flask is placed on the upper surface of the flask rack. A connecting tube is provided on the multi-necked flask, one end of which passes through the outer side of the multi-necked flask and is placed inside the flask. The multi-necked flask is connected to one end of the glass spring tube via the connecting tube and is in communication with the glass spring tube. The other end of the glass spring tube is connected to one end of the peristaltic pump pipe, and the other end of the peristaltic pump pipe is placed in the raw material cup. The baffle frame has an L-shaped cross-section and its position corresponds to that of the glass spring tube. The arc-shaped lamp top is placed above the glass spring tube, and its upper surface is fixedly connected to the lower surface of the L-shaped horizontal section of the baffle frame. Several illumination lamps are provided on the arc-shaped lamp top, and the illumination lamps are slidably connected to the lower surface of the arc-shaped lamp top.

[0006] When in use, the multi-necked flask, glass spring tube, peristaltic pump, raw material cup, flask rack, baffle, and curved lamp top are adapted according to the experimental content. The multi-necked flask and glass spring tube are connected by a connecting tube, and the other components are also connected together. If heating is required, an alcohol lamp can be added under the multi-necked flask in the flask rack. The experimental equipment consists of common laboratory equipment, which is small in size and convenient for experiments in limited spaces. The baffle can reduce interference from other light sources. The curved lamp top can be equipped with different lighting lamps to illuminate various positions of the experimental raw materials in the glass spring tube. Different light sources can also be installed to diversify the experimental conditions and make the direction of the light source easy to observe, which is convenient for teaching. This achieves the goal of making the experimental instruments simpler, adapting to the teaching environment, and enhancing the understanding of changes in experimental conditions.

[0007] Preferably, the multi-necked flask has several nozzles and several nozzle plugs, with each nozzle plug corresponding to a nozzle. The lower end of each nozzle plug is placed inside a nozzle and engages with it. The nozzle plugs facilitate sealing of other nozzles, reducing experimental errors.

[0008] Preferably, some of the stoppers have through holes, through which one end of the connecting tube on the multi-necked flask passes and is placed inside the flask. A rubber tube is attached to one end of the connecting tube, which is connected to a glass spring tube. The through holes in some of the stoppers facilitate the installation and fixing of the connecting tube, and the rubber tube is easy to bend and twist, saving space and providing a seal to prevent gas from escaping from the multi-necked flask after the experiment.

[0009] Preferably, the lower surface of the curved lamp top is provided with a sliding groove, the sliding groove having a T-shaped cross-section. The lamp has a retaining strip, which is fixedly connected to the lamp. The shapes of the retaining strip and the lamp are opposite to the shape of the sliding groove. The lamp engages with the curved lamp top through the cooperation of the retaining strip and the sliding groove. The T-shaped sliding groove facilitates both engagement with the retaining strip of the lamp and allows for sliding adjustment of its position.

[0010] Preferably, a color-transmitting plate is provided on the lower surface of the lamp, and the color-transmitting plate is snapped into the lower surface of the lamp. The color-transmitting plate can visually reflect the type of light used.

[0011] Preferably, the lower surface of the lamp is provided with a snap-fit ​​groove, and the color-transmitting plate is provided with a second snap-fit ​​strip. The second snap-fit ​​strip is fixedly connected to the color-transmitting plate, and the color-transmitting plate is snapped into the lower surface of the lamp through the cooperation of the second snap-fit ​​strip and the snap-fit ​​groove. The snap-fit ​​groove and the second snap-fit ​​strip facilitate the rotation and removal of the color-transmitting plate.

[0012] The beneficial effects of this utility model are: the experimental instruments are simpler, thus adapting to the teaching environment and enhancing the understanding of changes in experimental conditions; the tube plugs facilitate sealing other tube openings, reducing experimental errors; some tube plugs have through holes, facilitating the installation and fixing of connecting tubes; the rubber tubes are easy to bend and twist, saving space and providing a seal to prevent gas from escaping from the multi-necked flask after the experiment; the sliding slot is T-shaped, allowing it to both engage with and slide to adjust the position of the light lamp's clip; the color light-transmitting plate can visually reflect the type of light used; the snap-fit ​​slot and clip two facilitate the rotation and removal of the color light-transmitting plate.

[0020] like Figure 1 and Figure 3 As shown, the multi-necked flask 1 is provided with a number of nozzles 9 and a number of nozzle plugs 10. The nozzle plugs 10 correspond one-to-one with the nozzles 9, and the lower end of the nozzle plug 10 is placed inside the nozzle 9 and engaged with the nozzle 9.

[0021] like Figure 1 and Figure 3 As shown, a through hole 11 is provided on part of the tube stopper 10. One end of the connecting tube 4 on the multi-necked flask 1 passes through the through hole 11 and is placed inside the multi-necked flask 1.

[0022] like Figure 1 and Figure 4 As shown, a sliding groove 13 is provided on the lower end surface of the arc-shaped lamp top 7. The cross-sectional shape of the sliding groove 13 is T-shaped. A locking strip 14 is provided on the lamp 8. The locking strip 14 is fixedly connected to the lamp 8.

The sliding slot 13 of the curved lamp top 7 allows for the attachment of different lamps 8 via the clip 14 on the lamp 8, enabling illumination of various locations within the glass spring tube 2. Different light sources can also be installed. Since the colors of different lights cannot be observed with the naked eye, different colored light-transmitting plates 15 are inserted into the latch slots 16 on the lamp 8 via their clip 2 17, allowing light to pass through the plates and produce different colors. This diversifies experimental conditions and makes the direction and type of light source immediately apparent, facilitating teaching. The goal is to simplify experimental equipment, adapt it to the teaching environment, and enhance understanding of changing experimental conditions.
