Moreover, there are many dead zones in the pipeline connection, which can easily cause contamination risk and is difficult to guarantee the continuous aseptic property inside the reaction container, thereby affecting the accuracy of the reaction result.

In the description of the present application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise explicitly specified and limited.

For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0037] In the present application, unless otherwise explicitly specified and limited, if the first feature is described as "on" or "under" the second feature, etc., it can mean that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium.

[0039] In the biochemical reaction process, especially in the pharmaceutical and medical device industries that have high requirements for reaction conditions, it is necessary to avoid contamination of reaction materials in the reaction container by bacteria and other pollutants as much as possible to ensure the accuracy of the reaction results. Since the reaction container often needs to be connected to various types of equipment such as feeding equipment and discharging equipment through pipelines, the biochemical reaction system requires more equipment, and the overall equipment is poor. At this time, if a complex structure design is used for the reaction container to reduce the risk of pollution, it will increase the complexity of the reaction system, reduce the operation efficiency, and the cost is high. Moreover, when multiple devices are connected through pipelines, there are many dead zones inside the pipeline, which can easily cause material residues and microbial growth and cause pollution risks, making it difficult to ensure the continuous sterile properties inside the reaction container.

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

[0041] Referring to Figures 1 to 9 As shown in the drawings, the reaction device 10 in the embodiment of the present application is shown, and the reaction device 10 provided by the embodiment of the present application includes a shell 100, a light-emitting module 200 and a feeding valve 300.

[0042] The inside of the shell 100 has a reaction cavity 110 for accommodating reaction materials, and the shell 100 is provided with a first feeding channel 141 and a discharging channel 121 which communicate with the reaction cavity 110. Specifically, the shell 100 forms the outer contour of the reaction device 10, the inside of the shell 100 is hollow to form the reaction cavity 110, and the shell 100 is provided with the first feeding channel 141 and the discharging channel 121. Exemplarily, the first feeding channel 141 can be arranged at the top of the shell 100, so as to facilitate the entry of various types of reaction materials into the reaction cavity 110 for mixing and corresponding reaction. The discharging channel 121 can be arranged at the bottom of the shell 100, so as to facilitate the discharge of the reacted materials in the reaction cavity 110.

[0043] The light-emitting module 200 is connected to the shell 100, at least part of the light-emitting module 200 is located in the reaction cavity 110, and the light-emitting module 200 is configured to emit light to irradiate the reaction material in the reaction cavity 110. Specifically, the light-emitting module 200 is configured to penetrate the shell 100 and extend into the reaction cavity 110, and the part of the light-emitting module 200 located outside the shell 100 is used to externally connect a power supply. When the power supply is turned on, the part of the light-emitting module 200 located in the shell 100, i.e., in the reaction cavity 110, is used to emit light of a specific wavelength. The specific wavelength of light emitted by the light-emitting module 200 irradiating the reaction material in the reaction cavity 110 can have a specific effect. For example, when a sterile environment needs to be maintained in the reaction cavity 110, the light-emitting module 200 can be configured to emit ultraviolet light to kill bacteria and the like by using ultraviolet light; or when a photocatalytic reaction needs to be performed in the reaction cavity 110, the light-emitting module 200 can be configured to emit light of a required wavelength to provide a light irradiation environment.

[0044] The feed valve 300 has a first outlet 310, and the feed valve 300 is connected to the outer wall of the shell 100 so that the first outlet 310 is in alignment and communication with the first feed channel 141. Specifically, the feed valve 300 has an inlet and the first outlet 310, the inlet of the feed valve 300 is used to communicate with a feed device, the first outlet 310 of the feed valve 300 is used to align and communicate with the first feed channel 141, and the feed valve 300 is used to control the opening and closing of the path of the reaction material in the feed device to the reaction cavity 110. Wherein, the first outlet 310 is in alignment and communication with the first feed channel 141 means that in the state that the feed valve 300 is installed on the outer wall of the shell 100, the first outlet 310 of the feed valve 300 is attached to the surface of the outer wall of the shell 100 and is in communication with the first feed channel 141 arranged on the shell 100, so that the first outlet 310 of the feed valve 300 and the first feed channel 141 of the shell 100 do not need to be connected through 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 cavity 110 of the shell 100, emits light of a specific wavelength through the light-emitting module 200, and irradiates the reaction material in the reaction cavity 110. For example, by emitting ultraviolet light through the light-emitting module 200 to irradiate the reaction material, the sterilization effect can be achieved to maintain a sterile environment as much as possible. Moreover, the first outlet 310 of the feed valve 300 is arranged to be in alignment and communication with the first feed channel 141 of the shell 100, which can greatly shorten the length of the channel between the feed valve 300 and the shell 100, so that the spacing between the first outlet 310 of the feed valve 300 and the outer surface of the shell 100 is extremely small, i.e., the dead space between the feed valve 300 and the shell 100 is extremely small, thereby effectively reducing the risk of microbial growth caused by the dead space between the feed valve 300 and the shell 100.

[0046] Therefore, the reaction device 10 provided by the embodiments of the present application can realize the sterilization and other functions through the light-emitting module 200, and can also reduce the risk of microbial breeding caused by the dead zone, which is conducive to preventing the breeding of microorganisms inside the shell 100, so as to guarantee the continuous sterile property inside the reaction cavity 110 as much as possible, avoid the influence of the microorganisms and other pollutants on the reaction process in the reaction cavity 110, and ensure the accuracy of the reaction result.

[0047] Exemplarily, in some embodiments, the feeding valve 300 can be a multi-channel valve, that is, the feeding valve 300 has a plurality of inlets, which are all in communication with the first outlet 310. The plurality of inlets of the feeding valve 300 can be respectively used to communicate with different feeding devices, so as to supply different kinds of reaction materials to enter the reaction cavity 110 through the first outlet 310, thereby reducing the pollution risk when feeding multiple kinds of reaction materials.

[0048] In some embodiments, the light-emitting module 200 includes a light-emitting tube 210, a protection tube 220 and a connecting assembly 230, the protection tube 220 is arranged in the reaction cavity 110 and connected with the shell 100 through the connecting assembly 230, and the light-emitting tube 210 is connected with the connecting assembly 230 and extends into the protection tube 220. By sleeving the protection tube 220 outside the light-emitting tube 210, the light-emitting tube 210 can be protected to avoid being corroded and damaged by the reaction materials in the reaction cavity 110.

[0049] Referring to FIGS. 1, 2 and 3, Figure 4 and Figure 6 Exemplarily, in some embodiments, the protection tube 220 is a straight tube structure with an internal hollow, and is connected with the shell 100 through the connecting assembly 230, so as to be fixed in the reaction cavity 110. The main function of the protection tube 220 is to isolate the reaction materials in the reaction cavity 110 from the light-emitting tube 210, so as to avoid the contact and corrosion of the reaction materials to the light-emitting tube 210. Specifically, the light-emitting tube 210 is a straight tube structure with a smaller diameter than the protection tube 220, the light-emitting tube 210 is connected with the shell 100 through the connecting assembly 230, and the top end of the light-emitting tube 210 is used to externally connect the power supply through a pipeline, and the bottom end of the light-emitting tube 210 extends into the inside of the protection tube 220 located in the reaction cavity 110. When the top end of the light-emitting tube 210 is connected with the power supply, the light-emitting tube 210 will emit light and irradiate the reaction materials in the reaction cavity 110 through the protection tube 220, thereby achieving the sterilization and other effects.

[0050] Exemplarily, the protection tube 220 is a quartz tube with an internal hollow, so that the protection tube 220 has a certain structural strength, thereby effectively protecting the light-emitting tube 210 inside the protection tube 220, and at the same time, the protection tube 220 has a certain light transmittance, thereby ensuring that the light emitted by the light-emitting tube 210 can penetrate through the side wall of the protection tube 220.

[0051] It can be understood 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 arranged in the shapes of arc-shaped bent tubes, zigzag tubes, etc.

[0052] In some embodiments, the shell 100 includes a bottom cover 120, a side wall 130, and a top cover 140, two ends of the side wall 130 are connected with the bottom cover 120 and the top cover 140 respectively to enclose the reaction cavity 110, the bottom cover 120 is provided with a first mounting hole 122, the top cover 140 is provided with a second mounting hole 142, and the protection tube 220 is arranged through the first mounting hole 122 and the second mounting hole 142 by the connecting assembly 230. By arranging 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 connected and fixed with the bottom cover 120 and the top cover 140 respectively, which is beneficial to improve the connection strength between the protection tube 220 and the shell 100, thereby ensuring the connection stability between the light-emitting module 200 and the shell 100.

[0053] Referring to Figures 1 to 6 As shown in the drawings, for example, the bottom cover 120 and the top cover 140 are both in the form of circular plates, the side wall 130 is in the form of a hollow cylinder, and the bottom cover 120 and the top cover 140 are connected with the bottom and top of the side wall 130 by bolts and together enclose the cylindrical reaction cavity 110. The bottom cover 120 is provided with a discharge passage 121 and a first mounting hole 122, and the top cover 140 is provided with a first feeding passage 141 and a second mounting hole 142. The feeding valve 300 is connected to the first feeding passage 141 on the top cover 140, so that the first outlet 310 of the feeding valve 300 is in communication with the first feeding passage 141. The bottom of the protection tube 220 is closed, the top of the protection tube 220 is provided with an opening, and the bottom and top of the protection tube 220 are respectively clamped into the first mounting hole 122 and the second mounting hole 142 to be stably connected with the bottom cover 120 and the top cover 140. The light-emitting tube 210 is inserted into the protection tube 220 from the opening at the top of the protection tube 220, and the light-emitting tube 210 is connected to the top cover 140 by the connecting assembly 230, so that the light-emitting tube 210 is suspended in the protection tube 220. In this way, the top, side wall, and bottom of the light-emitting tube 210 are all spaced from the inner wall of the protection tube 220, so that the impact force of the reaction materials in the reaction cavity 110 on the protection tube 220 can not be directly transmitted to the light-emitting tube 210, thereby effectively avoiding damage to the light-emitting tube 210 due to force.

[0054] In some embodiments, the first mounting hole 122 and the second mounting hole 142 are coaxially arranged with the reaction cavity 110, and the protective tube 220 and the light-emitting tube 210 are mounted at the center of the reaction cavity 110 through the first mounting hole 122 and the second mounting hole 142, so that the light emitted by the light-emitting tube 210 is dispersed in all directions to uniformly irradiate all the reaction materials in the reaction cavity 110, thereby improving the sterilization effect of the light.

[0055] In some embodiments, the bottom end of the protective tube 220 is arranged in the first mounting hole 122, and the top end of the protective tube 220 is arranged in the second mounting hole 142; the connecting assembly 230 includes a first connecting piece 231, a second connecting piece 232, and a third connecting piece 233; the first connecting piece 231 is connected to the bottom cover 120, and the first connecting piece 231 is arranged outside the first mounting hole 122 to support the bottom end of the protective tube 220; the second connecting piece 232 is connected to the top cover 140, and the third connecting piece 233 is connected to the second connecting piece 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 piece 233 and extends into the protective tube 220 from the top end of the protective tube 220. In this embodiment, the first connecting piece 231 can support the protective tube 220 to support the bottom end of the protective tube 220, and the second connecting piece 232 and the third connecting piece 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 stably connected to the shell 100.

[0056] Specifically, referring to Figures 4 to 5 As shown in the figure, the first connecting piece 231 is arranged in a nut-like structure, the first connecting piece 231 is provided with external threads, and the first mounting hole 122 of the bottom cover 120 is provided with a threaded hole structure matched with the first connecting piece 231, and the first connecting piece 231 is connected to the bottom cover 120 through threads, thereby supporting the bottom of the protective tube 220. Referring to Figures 6 to 7 As shown in the figure, the second connecting piece 232 can be arranged in a flange structure, and the second connecting piece 232 is detachably connected to the top cover 140 through bolts, and the inside of the second connecting piece 232 is provided with a threaded through hole coaxial with and the same size as the second mounting hole 142. The third connecting piece 233 is threadedly connected to the second connecting piece 232 through the threaded through hole, so that the third connecting piece 233 and the third connecting piece 233 are detachable, and the bottom of the third connecting piece 233 abuts against the top of the protective tube 220, thereby supporting the top of the protective tube 220. The light-emitting tube 210 penetrates and is connected to the third connecting piece 233, thereby being connected and fixed to the second connecting piece 232 and the top cover 140 through the third connecting piece 233. In this way, the second connecting piece 232, the third connecting piece 233, and the top cover 140 are arranged in a detachable connection mode, which facilitates flexible mounting and dismounting of the protective tube 220 and the light-emitting tube 210.

[0057] In some embodiments, the connecting assembly 230 further includes a first seal 234; the first seal 234 is disposed within the first mounting hole 122 and fills the space between the outer wall of the protective tube 220 and the side wall of the first mounting hole 122. The first seal 234 can seal the gap between the protective tube 220 and the bottom cover 120, thereby improving the sealing performance of the reaction chamber 110 and preventing leakage of reactants.

[0058] For example, see Figure 5 As shown, the first seal 234 can be a sealing ring, which surrounds the protective tube 220 and fits against the side wall of the first mounting hole 122. Furthermore, Figure 5 The diagram illustrates a configuration with two sealing rings arranged vertically to enhance the sealing effect. It should be understood that the number of first seals 234 is not limited to two; in other alternative embodiments, the number of first seals 234 may be one, three, four, etc.

[0059] In some embodiments, the connecting assembly 230 further includes a second seal 235; the second seal 235 is disposed within the second mounting hole 142 and fills the space between the outer wall of the protective tube 220 and the side wall of the second mounting hole 142. The second seal 235 can seal the gap between the protective tube 220 and the top cover 140, thereby improving the sealing performance of the reaction chamber 110 and preventing leakage of reactants.

[0060] For example, see Figure 7 As shown, the second seal 235 can be a sealing ring, which surrounds the protective tube 220 and fits against the side wall of the second mounting hole 142. Furthermore, Figure 7 The diagram illustrates a configuration with two sealing rings arranged vertically to enhance the sealing effect. It should be understood that the number of second seals 235 is not limited to two; in other alternative embodiments, the number of second seals 235 may be one, three, four, etc.

[0061] In some embodiments, the light-emitting tube 210 is an ultraviolet lamp. 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, thus helping to meet the sterile environment requirements within the reaction chamber 110 as much as possible.

[0062] In some embodiments, the light emitting module 200 further comprises a light intensity sensor 240 connected to the shell 100 and in communication with the reaction cavity 110. The light intensity sensor 240 detects the light intensity in the reaction cavity 110, so that the light intensity can be adjusted in real time according to the reaction requirements to ensure the light effect. For example, the light intensity sensor 240 can be an ultraviolet intensity sensor, which detects the ultraviolet intensity and adjusts the ultraviolet intensity in real time to ensure the sterilization effect.

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

[0064] In some embodiments, the end of the first feeding channel 141 away from the reaction cavity 110 is in contact with the first outlet 310, and the diameter of the first feeding channel 141 is the same as the diameter of the first outlet 310. Specifically, as shown in Figure 6 and Figure 8 The first feeding channel 141 and the first outlet 310 are coaxially arranged along the vertical direction, and both are cylindrical through holes with the same diameter. In this way, by setting the diameter of the first feeding channel 141 to be the same as the diameter of the first outlet 310 and tightly butting the first feeding channel 141 and the first outlet 310, the dead zone at the connection between the first feeding channel 141 and the first outlet 310 can be reduced, so that the reaction device 10 of the present application can effectively avoid the risk of microbial growth caused by the dead zone in the traditional welding form when applied.

[0065] Further, in some embodiments, a first sealing gasket 320 is arranged between the shell 100 and the feeding valve 300. As shown in Figure 8 The first sealing gasket 320 surrounds the periphery of the first feeding channel 141 and the first outlet 310 in a ring shape, thereby sealing the gap between the shell 100 and the feeding valve 300, which can not only prevent the reaction material from leaking between the shell 100 and the feeding valve 300, but also prevent microbial growth at the gap between the shell 100 and the feeding valve 300, thereby improving the sterilization effect.

[0066] In some embodiments, the top of the shell 100 is provided with a second feeding channel 143 in communication with the reaction cavity 110; and the reaction device 10 further comprises a float ball valve 400 connected to the shell 100 and in communication with the reaction cavity 110 through the second feeding channel 143. Specifically, as shown inFigure 6 and Figure 9 As shown in FIG. 4, the second feeding channel 143 penetrates through the top of the shell 100 for connecting with a feeding device to add materials such as water into the reaction cavity 110. The float valve 400 is installed on the top of the shell 100 in a vertical direction. Depending on the mechanical structure of the float valve 400 itself, the float valve 400 can control the opening and closing of the second feeding channel 143 according to the liquid level in the reaction cavity 110, thereby achieving higher control stability without the need of electric or pneumatic valve control.

[0067] For example, referring to FIG. 4, the float valve 400 is arranged in the second feeding channel 143 and is bolted to the top cover 140 of the shell 100 by the pressing plate 410 to fix the float valve 400. A second sealing gasket 420 is arranged between the float valve 400 and the second feeding channel 143 to avoid liquid or gas leakage. Figure 9 In some embodiments, the reaction device 10 further comprises a discharge valve 500 having a second inlet, and the discharge valve 500 is connected to the outer wall of the shell 100 to make the second inlet abut and communicate with the discharge channel 121. Specifically, the discharge valve 500 can be welded to the outer wall of the shell 100, and the discharge valve 500 has the second inlet and at least one outlet. The second inlet of the discharge valve 500 abuts and communicates with the discharge channel 121, and the outlet of the discharge valve 500 is used to connect with other devices. The material in the reaction cavity 110 can be delivered to other devices through the discharge valve 500. The abutting and communicating of the second inlet with the discharge channel 121 means that the second inlet of the discharge valve 500 is attached to the surface of the outer wall of the shell 100 and communicates with the discharge channel 121 arranged on the shell 100 in the state that the discharge valve 500 is installed on the outer wall of 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 the material remaining between the discharge valve 500 and the shell 100 and further to avoid the growth of microorganisms.

[0068] In some embodiments, the reaction device 10 further comprises a water collecting tray 600 connected to the outer wall of the shell 100 to form a water collecting groove 610, and the opening of the water collecting groove 610 faces the feeding valve 300. Referring to FIG. 4, the water collecting groove 610 is arranged on the outer wall of the shell 100 and is connected to the discharge channel 121. The water collecting groove 610 is used to collect the water discharged from the discharge channel 121, and the water collecting groove 610 is connected to the feeding valve 300 to supply the water to the feeding valve 300.

[0069] Figure 1 ​As shown, the water collecting tray 600 is connected to the side wall 130 of the housing 100 and is formed with a water collecting groove 610, the water collecting groove 610 is located below the feed valve 300, the opening of the water collecting groove 610 faces upward, i.e. toward the feed valve 300, the water collecting groove 610 is used to collect the liquid leakage that may occur at the feed valve 300, so as to avoid the direct dripping of the liquid material to the ground and cause safety risks. Exemplarily, when the feed device is communicated with the inlet of the feed valve 300 through a pipeline, in some scenarios, the material needs to be sampled at the feed valve 300, then the pipeline communicated with the feed valve 300 needs to be disassembled, thereby causing the liquid leakage at the feed valve 300, at this time, the water collecting groove 610 can effectively collect the liquid leakage.
