[0039] In the process of biochemical reactions, especially in industries such as pharmaceuticals and medical devices that have high requirements for reaction conditions, it is necessary to avoid contamination of the reaction materials in the reaction vessel by bacteria and other pollutants as much as possible to ensure the accuracy of the reaction results. Since the reaction vessel often needs to be connected to various types of equipment such as feeding equipment and discharging equipment through pipelines, the entire biochemical reaction system requires a large number of equipment and the equipment integrity is poor. At this time, if a complex structural design of the reaction vessel is adopted to reduce the risk of contamination, it will increase the equipment complexity of the reaction system, reduce operating efficiency, and be costly. In addition, when multiple devices are connected through pipelines, there are many dead zones inside the pipeline, which can easily lead to material residues and microbial growth, causing contamination risks, and it is difficult to ensure the continuous sterility of the reaction vessel.

[0040] In order to solve at least part of the above technical problems, an embodiment of the present application provides a reaction device.

[0041] See Figures 1 to Fig. 9 As shown, there is a structural schematic diagram of the reaction device 10 in the embodiment of the present application. The reaction device 10 provided in the embodiment of the present application includes a shell 100, a light emitting module 200 and a feed valve 300.

[0042] The shell 100 has a reaction chamber 110 for accommodating reaction materials inside, and the shell 100 is provided with a first feed channel 141 and a discharge channel 121 connected to the reaction chamber 110. Specifically, the shell 100 forms the outer profile of the reaction device 10, the inside of the shell 100 is hollow to form the reaction chamber 110, and the shell 100 is provided with a first feed channel 141 and a discharge channel 121. Exemplarily, the first feed channel 141 can be arranged at the top of the shell 100, so as to facilitate various types of reaction materials to enter the reaction chamber 110 for mixing and corresponding reactions. The discharge channel 121 can be arranged at the bottom of the shell 100, so as to facilitate the discharge of the materials in the reaction chamber 110 after the reaction is completed.

[0043] The light-emitting module 200 is connected to the housing 100, and at least part of the light-emitting module 200 is located in the reaction chamber 110. The light-emitting module 200 is configured to emit light to illuminate the reaction materials in the reaction chamber 110. Specifically, the light-emitting module 200 is configured to penetrate the housing 100 and extend into the reaction chamber 110, and the part of the light-emitting module 200 located outside the housing 100 is used for an external power supply. When the power is turned on, the part of the light-emitting module 200 located in the housing 100, that is, in the reaction chamber 110, is used to emit light of a specific wavelength. The light of a specific wavelength emitted by the light-emitting module 200 irradiating the reaction materials in the reaction chamber 110 can have a specific effect. For example, when a sterile environment needs to be maintained in the reaction chamber 110, the light-emitting module 200 can be configured to emit ultraviolet rays to use ultraviolet rays to sterilize; or, when a photocatalytic reaction needs to be performed in the reaction chamber 110, the light-emitting module 200 can be configured to emit light of a required wavelength to provide a lighting environment.

[0044] The feed valve 300 has a first outlet 310, and the feed valve 300 is connected to the outer wall of the housing 100 so that the first outlet 310 is docked and communicated with the first feed channel 141. Specifically, the feed valve 300 has an inlet and a first outlet 310, the inlet of the feed valve 300 is used to connect with the feed device, the first outlet 310 of the feed valve 300 is used to dock and communicate with the first feed channel 141, and the feed valve 300 is used to control the on-off of the path of the reaction material in the feed device entering the reaction chamber 110. Among them, the first outlet 310 docking and communicating with the first feed channel 141 means that when the feed valve 300 is installed on the outer wall of the housing 100, the first outlet 310 of the feed valve 300 is attached to the outer wall surface of the housing 100 and communicated with the first feed channel 141 provided on the housing 100, so that the first outlet 310 of the feed valve 300 and the first feed channel 141 of the housing 100 do not need to be connected by an additional pipeline.

[0045] Through the above structural design, the reaction device 10 of the embodiment of the present application sets the light emitting module 200 to extend into the reaction chamber 110 of the shell 100, and emits light of a specific wavelength through the light emitting module 200 and irradiates the reaction material in the reaction chamber 110, for example, the light emitting module 200 emits ultraviolet rays to irradiate the reaction material, so as to achieve a sterilization effect, so as to maintain a sterile environment as much as possible. In addition, the first outlet 310 of the feed valve 300 is set to dock and communicate with the first feed channel 141 of the shell 100, so that the length of the channel between the feed valve 300 and the shell 100 can be greatly shortened, so that the distance between the first outlet 310 of the feed valve 300 and the outer surface of the shell 100 is extremely small, that is, the dead zone between the feed valve 300 and the shell 100 is extremely small, so that the risk of microbial growth caused by the dead zone between the feed valve 300 and the shell 100 can be effectively reduced.

[0046] Therefore, the reaction device 10 provided in the embodiment of the present application can achieve functions such as sterilization through the light-emitting module 200, and at the same time can reduce the risk of microbial growth caused by the dead zone, which is beneficial to prevent the growth of microorganisms inside the shell 100, thereby ensuring the continuous sterility of the inside of the reaction chamber 110 as much as possible, avoiding microorganisms and other contaminants from affecting the reaction process in the reaction chamber 110, and ensuring the accuracy of the reaction results.

[0047] For example, in some embodiments, the feed valve 300 may be a multi-channel valve, that is, the feed valve 300 has multiple inlets, and the multiple inlets are all connected to the first outlet 310. The multiple inlets of the feed valve 300 can be used to connect different feeding devices, so that different types of reaction materials can enter the reaction chamber 110 through the first outlet 310, thereby reducing the risk of contamination when multiple types of reaction materials are added.

[0048] In some embodiments, the light-emitting module 200 includes a light-emitting tube 210, a protective tube 220, and a connecting assembly 230. The protective tube 220 is disposed in the reaction chamber 110 and connected to the housing 100 through the connecting assembly 230. The light-emitting tube 210 is connected to the connecting assembly 230 and extends into the protective tube 220. By sleeved over the light-emitting tube 210, the light-emitting tube 210 can be protected to prevent the reaction materials in the reaction chamber 110 from corroding and damaging the light-emitting tube 210.

[0049] See also Figure 4 and Figure 6 As shown, in some embodiments, the protection tube 220 is a straight tube structure with a hollow interior, and is connected to the housing 100 through a connecting assembly 230, so as to be fixed in the reaction chamber 110. The main function of the protection tube 220 is to isolate the reaction materials in the reaction chamber 110 from the light-emitting tube 210 to prevent the reaction materials from contacting and corroding the light-emitting tube 210. Specifically, the light-emitting tube 210 is a straight tube structure with a diameter smaller than that of the protection tube 220. The light-emitting tube 210 is connected to the housing 100 through the connecting assembly 230, and the top end of the light-emitting tube 210 is used to connect an external power source through a pipeline, and the bottom end of the light-emitting tube 210 extends into the protection tube 220 located in the reaction chamber 110. When the top end of the light-emitting tube 210 is connected to the power source, the light-emitting tube 210 will emit light and irradiate the reaction materials in the reaction chamber 110 through the protection tube 220, thereby achieving sterilization and other effects.

[0050] Exemplarily, the protection tube 220 is a hollow quartz tube, which makes the protection tube 220 have a certain structural strength, thereby effectively protecting the light-emitting tube 210 inside it, and at the same time makes the protection tube 220 have a certain light transmittance, thereby ensuring that the light emitted by the light-emitting tube 210 can penetrate the side wall of the protection tube 220.

[0051] It is understandable that in other optional embodiments, the structures of the protection tube 220 and the light-emitting tube 210 are not limited to straight tube shapes. For example, the protection tube 220 and the light-emitting tube 210 can also be configured as arc-shaped tubes, broken-line tubes, and the like.

[0052] In some embodiments, the housing 100 includes a bottom cover 120, a side enclosure 130, and a top cover 140, the two ends of the side enclosure 130 are respectively connected to the bottom cover 120 and the top cover 140 to enclose the reaction chamber 110, the bottom cover 120 is provided with a first mounting hole 122, and the top cover 140 is provided with a second mounting hole 142; the protection tube 220 is passed through the first mounting hole 122 and the second mounting hole 142 through the connection assembly 230. By simultaneously passing the protection tube 220 through the first mounting hole 122 on the bottom cover 120 and the second mounting hole 142 on the top cover 140, the two ends of the protection tube 220 are respectively connected and fixed to the bottom cover 120 and the top cover 140, which is conducive to improving the connection strength between the protection tube 220 and the housing 100, thereby ensuring the connection stability between the light emitting module 200 and the housing 100.

[0053] See Figures 1 to Figure 6 As shown, illustratively, the bottom cover 120 and the top cover 140 are both circular plate-like structures, and the side enclosure 130 is a hollow cylindrical structure. The bottom cover 120 and the top cover 140 are respectively connected to the bottom and top of the side enclosure 130 by bolts and together form a cylindrical reaction chamber 110. The bottom cover 120 is provided with a discharge channel 121 and a first mounting hole 122, and the top cover 140 is provided with a first feed channel 141 and a second mounting hole 142. The feed valve 300 is connected to the first feed channel 141 on the top cover 140 so that the first outlet 310 of the feed valve 300 is connected to the first feed channel 141. The bottom of the protection tube 220 is closed, and the top of the protection tube 220 is provided with an opening. The bottom and top of the protection tube 220 are respectively inserted into the first mounting hole 122 and the second mounting hole 142 so as to be firmly connected with the bottom cover 120 and the top cover 140. The light-emitting tube 210 is inserted into the protective tube 220 from the opening at the top of the protective tube 220, and the light-emitting tube 210 is connected to the top cover 140 through the connecting assembly 230, so that the light-emitting tube 210 is suspended in the protective tube 220. Therefore, there is a gap between the top, side wall and bottom of the light-emitting tube 210 and the inner wall of the protective tube 220, so that the impact force of the reaction material in the reaction chamber 110 on the protective tube 220 can be prevented from being directly transmitted to the light-emitting tube 210, thereby effectively preventing the light-emitting tube 210 from being damaged by the force.

[0054] In some embodiments, the first mounting hole 122 and the second mounting hole 142 are coaxially arranged with the reaction chamber 110. At this time, the protection tube 220 and the light-emitting tube 210 are installed at the center of the reaction chamber 110 through the first mounting hole 122 and the second mounting hole 142, so that the light emitted by the light-emitting tube 210 can be diffused to all sides to evenly illuminate all the reaction materials in the reaction chamber 110, thereby improving the sterilization effect of the light.

[0055] In some embodiments, the bottom end of the protective tube 220 is passed through the first mounting hole 122, and the top end of the protective tube 220 is passed through the second mounting hole 142; the connecting assembly 230 includes a first connecting member 231, a second connecting member 232 and a third connecting member 233; the first connecting member 231 is connected to the bottom cover 120, and the first connecting member 231 is arranged outside the first mounting hole 122 to form a support for the bottom end of the protective tube 220; the second connecting member 232 is connected to the top cover 140, and the third connecting member 233 is connected to the second connecting member 232 and extends into the first mounting hole 122 to abut against the top end of the protective tube 220; the light-emitting tube 210 is connected to the third connecting member 233 and extends into the protective tube 220 from the top end of the protective tube 220. In this embodiment, the first connecting member 231 can support the protective tube 220 to form a support for the bottom end of the protective tube 220, and the second connecting member 232 and the third connecting member 233 can support the top of the protective tube 220 and fix the light-emitting tube 210 on the top cover 140, thereby ensuring that the protective tube 220 and the light-emitting tube 210 are firmly connected to the shell 100.

[0056] Specifically, see Figures 4 to 5 As shown, the first connecting member 231 is configured as a nut-like structure, the first connecting member 231 is provided with external threads, the first mounting hole 122 of the bottom cover 120 is provided with a threaded hole structure matched with the first connecting member 231, and the first connecting member 231 is connected to the bottom cover 120 through threads, thereby forming a support for the bottom of the protection tube 220. Figure 6 to Figure 7 As shown, the second connecting member 232 can be set as a flange structure, and the second connecting member 232 is detachably connected to the top cover 140 by bolts, and a threaded through hole coaxial with the second mounting hole 142 and having the same size is provided inside the second connecting member 232. The third connecting member 233 is threadedly connected to the second connecting member 232 through the threaded through hole, so that the third connecting member 233 and the third connecting member 233 are detachable, and the bottom of the third connecting member 233 abuts against the top of the protective tube 220, thereby forming a support for the top of the protective tube 220. The light-emitting tube 210 penetrates and is connected to the third connecting member 233, so as to be connected and fixed to the second connecting member 232 and the top cover 140 through the third connecting member 233. Thus, the second connecting member 232, the third connecting member 233 and the top cover 140 are set in a mutually detachable connection mode, which is convenient for flexible installation and removal of the protective tube 220 and the light-emitting tube 210.

[0057] In some embodiments, the connection assembly 230 further includes a first seal 234; the first seal 234 is disposed in the first mounting hole 122, and the first seal 234 is filled between the outer wall of the protection tube 220 and the side wall of the first mounting hole 122. The first seal 234 can seal the gap between the protection tube 220 and the bottom cover 120, thereby improving the sealing of the reaction chamber 110 and preventing the reaction material from leaking.

[0058] For example, see Figure 5 As shown, the first sealing member 234 may be a sealing ring, which surrounds the protection tube 220 and fits against the side wall of the first mounting hole 122. Figure 5 2 shows a case where two sealing rings are arranged in the vertical direction to enhance the sealing effect. It should be understood that the number of the first sealing members 234 is not limited to two. In other optional embodiments, the number of the first sealing members 234 can be one, three, four, etc.

[0059] In some embodiments, the connection assembly 230 further includes a second seal 235; the second seal 235 is disposed in the second mounting hole 142, and the second seal 235 is filled between the outer wall of the protection tube 220 and the side wall of the second mounting hole 142. The second seal 235 can seal the gap between the protection tube 220 and the top cover 140, thereby improving the sealing of the reaction chamber 110 and preventing leakage of reaction materials.

[0060] For example, see Figure 7 As shown, the second sealing member 235 may be a sealing ring, which surrounds the protection tube 220 and fits the side wall of the second mounting hole 142. Figure 7 2 shows a case where two sealing rings are arranged in the vertical direction to enhance the sealing effect. It should be understood that the number of the second sealing members 235 is not limited to two. In other optional embodiments, the number of the second sealing members 235 can be one, three, four, etc.

[0061] In some embodiments, the light-emitting tube 210 is an ultraviolet lamp tube. When the light-emitting tube 210 is powered on, it can emit ultraviolet light, which can remove pollutants such as residual chlorine, organic matter, and microorganisms, thereby helping to meet the aseptic environment requirements in the reaction chamber 110 as much as possible.

[0062] In some embodiments, the light emitting module 200 further includes a light intensity sensor 240, which is connected to the housing 100 and communicates with the reaction chamber 110. The light intensity in the reaction chamber 110 is detected by the light intensity sensor 240, so that the light intensity can be adjusted in real time according to the reaction needs to ensure the lighting effect. Exemplarily, the light intensity sensor 240 can be an ultraviolet intensity sensor, which detects the ultraviolet intensity and can perform real-time ultraviolet intensity frequency adjustment to ensure the sterilization effect.

[0063] In some embodiments, the inner wall of the reaction chamber 110 is subjected to surface polishing. Specifically, in this embodiment, the inner wall of the reaction chamber 110 may be electropolished to a mirror effect, so that the inner wall surface of the reaction chamber 110 can achieve a total light reflection effect, thereby enhancing the penetration ability of the light emitted by the light-emitting tube 210, such as ultraviolet rays, and further continuously killing microorganisms in the reaction chamber 110, thereby improving the sterilization effect.

[0064] In some embodiments, one end of the first feed channel 141 away from the reaction chamber 110 is in contact with the first outlet 310, and the diameter of the first feed channel 141 is the same as the diameter of the first outlet 310. Figure 6 and Figure 8 As shown, the first feed channel 141 and the first outlet 310 both extend in the vertical direction and are coaxially arranged, and the first feed channel 141 and the first outlet 310 are both cylindrical through holes with the same diameter. Therefore, by setting the diameter of the first feed channel 141 to be the same as the diameter of the first outlet 310, and the first feed channel 141 and the first outlet 310 are closely connected, it is helpful to reduce the dead zone at the connection between the first feed channel 141 and the first outlet 310, so that the reaction device 10 of the embodiment of the present application can effectively avoid the risk of microbial breeding caused by the dead zone of the traditional welding form when used.

[0065] Furthermore, in some embodiments, a first sealing gasket 320 is disposed between the housing 100 and the feed valve 300. Figure 8 As shown, the first sealing gasket 320 is annularly arranged around the first feed channel 141 and the first outlet 310, thereby blocking the gap between the shell 100 and the feed valve 300. This can prevent the reaction material from leaking from between the shell 100 and the feed valve 300, and can also prevent the growth of microorganisms in the gap between the shell 100 and the feed valve 300, so as to improve the sterilization effect.

[0066] In some embodiments, the top of the housing 100 is provided with a second feed channel 143 communicating with the reaction chamber 110; the reaction device 10 further includes a float valve 400, which is connected to the housing 100 and communicates with the reaction chamber 110 through the second feed channel 143. Figure 6 and Fig. 9 As shown, the second feed channel 143 runs through the top of the housing 100 and is used to connect an external feed device to add materials, such as water, into the reaction chamber 110. The float valve 400 is vertically mounted on the top of the housing 100. Relying on the mechanical structure of the float valve 400 itself, the float valve 400 can control the on-off of the second feed channel 143 according to the liquid level in the reaction chamber 110, thereby eliminating the need for electric or pneumatic valve control, and providing higher control stability.

[0067] For example, see Fig. 9 As shown, the float valve 400 is inserted into the second feed channel 143 and is bolted to the top cover 140 of the housing 100 through the pressing plate 410 to fix the float valve 400. A second sealing gasket 420 is provided between the float valve 400 and the second feed channel 143, and sealing by the second sealing gasket 420 can prevent liquid or gas leakage.

[0068] In some embodiments, the reaction device 10 further includes a discharge valve 500, the discharge valve 500 has a second inlet, and the discharge valve 500 is connected to the outer wall of the housing 100 so that the second inlet is docked and communicated with the discharge channel 121. Specifically, the discharge valve 500 can be welded to the outer wall of the housing 100, the discharge valve 500 has a second inlet and at least one outlet, the second inlet of the discharge valve 500 is docked and communicated with the discharge channel 121, and the outlet of the discharge valve 500 is used to connect to other equipment. The discharge valve 500 can be used to control the material in the reaction chamber 110 to be transported to other equipment. Among them, the second inlet is connected and connected with the discharge channel 121, which means that when the discharge valve 500 is installed on the outer wall of the shell 100, the second inlet of the discharge valve 500 is attached to the outer wall surface of the shell 100 and is connected with the discharge channel 121 arranged on the shell 100, so that the second inlet of the discharge valve 500 and the discharge channel 121 of the shell 100 do not need to be connected by an additional pipeline, which is beneficial to avoid material residue between the discharge valve 500 and the shell 100, and further avoid the growth of microorganisms.

[0069] In some embodiments, the reaction device 10 further includes a water collecting tray 600, which is connected to the outer wall of the housing 100 and forms a water collecting tank 610, and the opening of the water collecting tank 610 faces the feed valve 300. Referring to FIG. 1, the water collecting tray 600 is connected to the side 130 of the housing 100 and is formed with a water collecting tank 610, which is located below the feed valve 300, and the opening of the water collecting tank 610 faces upward, that is, toward the feed valve 300. The water collecting tank 610 is used to collect the leakage that may occur at the feed valve 300 to prevent the liquid material from directly dripping onto the ground and causing safety risks. For example, when the feed device is connected to the inlet of the feed valve 300 through a pipeline, in some scenarios, it is necessary to sample the material at the feed valve 300, and it is necessary to disassemble the pipeline connected to the feed valve 300, which may cause leakage at the feed valve 300. At this time, the leakage can be effectively collected through the water collecting tank 610.
