Description

Technical Field

[0001] This application belongs to the field of lighting technology, and more specifically, relates to a special box for explosion-proof lighting fixtures in the fermentation room of a koji-making workshop. Background Technology

[0002] In the winemaking industry, the auxiliary material used in the fermentation room of the koji-making workshop during the fermentation process of the koji is straw, which is flammable. Therefore, fire safety requirements do not allow the installation of fixed lighting fixtures in the fermentation room.

[0003] Currently, workers in the fermentation room need outdoor lighting or hand-held flashlights to illuminate their work when turning and removing koji. However, outdoor lighting sometimes fails to meet the required illumination. Using hand-held flashlights also disrupts work and reduces efficiency. Therefore, there is an urgent need for a fire-safe lighting device that can be installed indoors in the fermentation room. Summary of the Invention

[0004] The purpose of this application is to provide a special box for explosion-proof lighting fixtures in the fermentation room of a koji-making workshop, so as to solve the problem that existing lighting devices in the related technology cannot meet the lighting needs of workers when working in the fermentation room while meeting fire safety requirements.

[0005] To achieve the above objectives, the technical solution adopted in the embodiments of this application is as follows:

[0006] On the one hand, a special box for explosion-proof lighting fixtures in the fermentation room of a koji-making workshop is provided.

[0007] include:

[0008] The housing includes a housing having a receiving chamber and a front cover and a rear cover respectively covering both ends of the housing. A fixing plate is provided inside the housing, and the fixing plate divides the receiving chamber into a first mounting chamber and a second mounting chamber.

[0009] An explosion-proof lamp is installed in the first mounting cavity, with the light-emitting end of the explosion-proof lamp extending out of the front cover;

[0010] An air inlet assembly is installed in the second mounting cavity. The air inlet end of the air inlet assembly is connected to the outside of the housing, and the air outlet end of the air inlet assembly is connected to the first mounting cavity.

[0011] An exhaust assembly is installed in the second mounting cavity and spaced apart from the air inlet assembly. The air inlet end of the exhaust assembly is connected to the first mounting cavity, and the air outlet end of the exhaust assembly is connected to the outside of the housing.

[0012] In one embodiment, a mounting cylinder is provided on the side of the fixing plate facing the front cover, the explosion-proof lamp is installed inside the mounting cylinder, and the end of the mounting cylinder away from the fixing plate abuts against the front cover; a first through hole and a second through hole are respectively opened on the side wall of the mounting cylinder, the first through hole connects the first mounting cavity and the mounting cylinder, and the air inlet end of the exhaust assembly extends into the second through hole.

[0013] This structure facilitates the installation of explosion-proof lighting fixtures by incorporating a mounting cylinder. The mounting cylinder also limits the position of the fixing plate, preventing the light-emitting end of the explosion-proof lighting fixture from extending excessively out of the front cover. Simultaneously, a first and second through-hole are provided on the side wall of the mounting cylinder. The air inlet of the exhaust assembly extends into the second through-hole, preventing excessive pressure inside the mounting cylinder from causing hot air generated by the explosion-proof lighting fixture to escape from the front cover of the outer casing.

[0014] In one embodiment, the front cover has an assembly hole for the light-emitting end of the explosion-proof lamp to extend out, and a sealing ring is installed between the light-emitting end of the explosion-proof lamp and the assembly hole.

[0015] This structure uses a sealing ring to seal the light-emitting end of the explosion-proof lamp with the mounting hole, preventing the heat generated by the explosion-proof lamp from escaping from the front cover of the housing.

[0016] In one embodiment, an annular groove is formed on the outer peripheral surface of the sealing ring for the edge of the mounting hole to extend into.

[0017] This structure prevents the sealing ring from falling off the assembly hole.

[0018] In one embodiment, the air intake assembly includes an air intake duct and an air intake fan. The air intake fan is mounted on the housing. The air intake end of the air intake duct is connected to the air intake fan. The air outlet end of the air intake duct passes through the fixing plate and extends into the first mounting cavity.

[0019] The exhaust assembly includes an exhaust duct and an exhaust fan. The exhaust fan is mounted on the housing. The air inlet of the exhaust duct is connected to the second through hole of the mounting cylinder. The air outlet of the exhaust duct passes through the fixing plate and is connected to the exhaust fan.

[0020] This structure allows the intake fan to draw in cool outdoor air into the first mounting chamber when it rotates, and the exhaust fan to expel hot air from the first mounting chamber when it rotates.

[0021] In one embodiment, the explosion-proof lighting box for the fermentation room in the koji-making workshop further includes a filter screen and an air inlet grille. The air inlet grille is installed on the side of the air inlet fan away from the air inlet duct, and the filter screen is installed between the air inlet fan and the air inlet grille.

[0022] This structure, by incorporating filters and air inlet grilles, prevents outdoor impurities and dust from entering the casing and affecting the reliable operation of the explosion-proof lighting box in the fermentation room of the koji-making workshop.

[0023] In one embodiment, the explosion-proof light fixture box in the fermentation room of the koji-making workshop further includes a conduit through which the cable of the explosion-proof light fixture passes, one end of the conduit being connected to the explosion-proof light fixture, and the other end of the conduit extending out of the outer shell.

[0024] This structure allows the cables of the explosion-proof lighting fixtures to be routed to the outside of the housing via conduits.

[0025] In one embodiment, a perforation is formed on the sidewall of the conduit.

[0026] With this structure, the cables for the intake and exhaust fans can be inserted into the conduit through the through-hole and then exit to the outside of the housing.

[0027] In one embodiment, both the inner and outer surfaces of the housing are coated with a corrosion-resistant and thermally conductive coating.

[0028] This structure features a corrosion-resistant and thermally conductive coating that prevents the outer shell from corroding. Furthermore, when air flows through the first mounting cavity, it can carry away the heat from the cavity more quickly, thus improving the heat dissipation efficiency of the explosion-proof lighting box in the fermentation room of the koji-making workshop.

[0029] In one embodiment, the edges of the front cover and the rear cover are respectively provided with flanges parallel to the sidewalls of the housing, and the flanges of the front cover and the rear cover respectively cover the sidewalls of the housing.

[0030] This structure increases the sealing effect of the housing, preventing the heat generated by the explosion-proof lamp from escaping through the gap between the housing and the front or rear cover.

[0031] The beneficial effects of the explosion-proof lighting box for the fermentation room in the koji-making workshop provided in this application are as follows: A fixing plate is installed inside the shell, dividing the accommodating chamber of the shell into a first mounting chamber and a second mounting chamber. The explosion-proof lighting fixture is installed in the first mounting chamber, with the light-emitting end of the fixture extending out of the front cover. An air inlet assembly and an air outlet assembly are installed in the second mounting chamber. The air inlet assembly introduces cold outdoor air into the first mounting chamber, and the air outlet assembly exhausts hot air from the first mounting chamber. In use, the explosion-proof lighting box for the fermentation room in the koji-making workshop can be pre-embedded in the wall of the fermentation room, with the light-emitting end of the explosion-proof lighting fixture facing the interior of the fermentation room. The air inlet of the air inlet assembly and the air outlet of the air outlet assembly are both located outdoors. In this way, the explosion-proof lighting box for the fermentation room in the koji-making workshop can meet the lighting needs of workers during operation, and the heat generated by the explosion-proof lighting fixture is dissipated outdoors through the air inlet and air outlet assemblies, complying with fire safety regulations.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0060] Throughout this specification, references to "an embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic described in connection with an embodiment is included in at least one embodiment of this application. Therefore, the phrases "in one embodiment" or "in some embodiments" appear in various places throughout the specification, and not all refer to the same embodiment. Furthermore, in one or more embodiments, particular features, structures, or characteristics may be combined in any suitable manner.

[0061] Please see Figures 1-3 The explosion-proof lighting box for the fermentation room of a koji-making workshop provided in this application will now be described. This explosion-proof lighting box includes a shell 1, an explosion-proof lighting fixture 2, an air inlet assembly 3, and an exhaust assembly 4. The shell 1 is a rectangular box structure, specifically comprising a housing 11 with a accommodating chamber and a front cover 12 and a rear cover 13 respectively covering both ends of the shell 11. Indicatively, fasteners can be used to secure the front cover 12 and the rear cover 13 to the shell 11 to ensure the structural stability of the shell 1.

[0062] An internal fixing plate 14 is provided inside the housing 1, dividing the accommodating chamber into a first mounting cavity and a second mounting cavity. Specifically, the area inside the housing 1 located on the side of the fixing plate 14 facing the front cover 12 is the first mounting cavity, and the area located on the side of the fixing plate 14 facing the rear cover 13 is the second mounting cavity. The explosion-proof lamp 2 is installed in the first mounting cavity, wherein the explosion-proof lamp 2 can be installed in the mounting cavity by fastening with fasteners. The light-emitting end 21 of the explosion-proof lamp 2 extends out of the front cover 12. It is easy to understand that the front cover 12 has a mounting hole for the light-emitting end 21 of the explosion-proof lamp 2 to pass through. In one possible implementation, the light-emitting end 21 of the explosion-proof lamp 2 can be sealed to the mounting hole, for example, by applying sealant to the gap between the light-emitting end 21 and the mounting hole to prevent the heat generated by the explosion-proof lamp 2 from escaping from the gap between the light-emitting end 21 and the mounting hole. This embodiment does not limit the specific structure of the explosion-proof lamp 2. Those skilled in the art can select a suitable explosion-proof lamp 2 according to actual needs. Of course, commercially available explosion-proof lamps 2 can also be selected. Using explosion-proof lamp 2 as the light source for the explosion-proof lamp box in the fermentation room of the koji-making workshop can ensure the safety of the explosion-proof lamp box. At the same time, explosion-proof lamp 2 has a good heat dissipation effect, and the air inlet component 3 and the air outlet component 4 can dissipate the heat generated by explosion-proof lamp 2 more quickly.

[0063] The air inlet assembly 3 is installed in the second mounting cavity. The air inlet end of the air inlet assembly 3 communicates with the outside of the housing 1, and the air outlet end of the air inlet assembly 3 communicates with the first mounting cavity. Those skilled in the art can fix the air inlet end of the air inlet assembly 3 to the side wall or rear cover 13 of the housing 11 according to actual needs. The air outlet end of the air inlet assembly 3 passes through the fixing plate 14 and extends into the first mounting cavity. When the air inlet assembly 3 is working, it can blow cold outdoor air into the first mounting cavity. The exhaust assembly 4 is installed in the second mounting cavity and spaced apart from the air inlet assembly 3. The air inlet end of the exhaust assembly 4 communicates with the first mounting cavity, and the air outlet end of the exhaust assembly 4 communicates with the outside of the housing 1. Specifically, the air inlet end of the exhaust assembly 4 is located in the first mounting cavity, and the air outlet end of the exhaust assembly 4 can be fixed to the side wall or rear cover 13 of the housing 11 after passing through the fixing plate 14. In one possible implementation, the air intake assembly 3 and the air exhaust assembly 4 are respectively arranged on opposite sides of the explosion-proof lamp 2, so that the air intake assembly 3 and the air exhaust assembly 4 can carry away the heat generated by the explosion-proof lamp 2 when they are working.

[0064] The beneficial effects of the explosion-proof lighting box for the fermentation room in the koji-making workshop provided in this embodiment are as follows: A fixing plate 14 is installed inside the shell 11, which divides the accommodating chamber of the shell 11 into a first mounting chamber and a second mounting chamber. The explosion-proof lighting fixture 2 is installed in the first mounting chamber, and the light-emitting end 21 of the explosion-proof lighting fixture 2 extends out of the front cover 12. When the explosion-proof lighting fixture 2 is working, the heat generated by it is relatively concentrated in the first mounting chamber. The explosion-proof lighting box for the fermentation room in the koji-making workshop is also provided with an air inlet assembly 3 and an air outlet assembly 4. The air inlet assembly 3 introduces cold outdoor air into the first mounting chamber, and the air outlet assembly 4 exhausts the hot air from the first mounting chamber. When in use, the explosion-proof lighting box for the fermentation room in the koji-making workshop can be pre-embedded in the wall of the fermentation room, with the light-emitting end 21 of the explosion-proof lighting fixture 2 facing the interior of the fermentation room, and the air inlet end of the air inlet assembly 3 and the air outlet end of the air outlet assembly 4 both located outside the fermentation room. In this way, the explosion-proof light fixture box in the fermentation room of the koji-making workshop can meet the lighting needs of workers during operation, and the heat generated by the explosion-proof light fixture 2 is dissipated to the outside of the fermentation room through the air intake component 3 and the exhaust component 4, which meets fire safety requirements.

[0065] In one embodiment, see Figure 2 and Figure 6 As a specific embodiment of the explosion-proof lighting fixture box for the fermentation room of the koji-making workshop provided in this application, a mounting cylinder 15 is provided on the side of the fixing plate 14 facing the front cover 12. The cross-sectional shape of the mounting cylinder 15 can be circular or square, or other suitable shapes, and is not limited to a single shape. The explosion-proof lighting fixture 2 is installed inside the mounting cylinder 15. Exemplarily, a support base for supporting the explosion-proof lighting fixture 2 is provided inside the mounting cylinder 15, and a mounting seat abutting against the support base is provided on the edge of the explosion-proof lighting fixture 2. Fasteners can be used to fasten the mounting seat to the support base. Indicatively, the mounting cylinder 15 and the fixing plate 14 can be fixed by welding. The end of the mounting cylinder 15 away from the fixing plate 14 abuts against the front cover 12. The installation cylinder 15 facilitates the installation of the explosion-proof lamp 2. The installation cylinder 15 can limit the fixing plate 14 to prevent the light-emitting end 21 of the explosion-proof lamp 2 from extending too far from the front cover 12. This ensures that after the explosion-proof lamp box is installed in the fermentation room of the koji-making workshop, the explosion-proof lamp 2 will not emit heat into the fermentation room, which complies with fire safety.

[0066] A first through hole 151 and a second through hole 152 are respectively provided on the side wall of the mounting cylinder 15. The first through hole 151 connects the first mounting cavity and the mounting cylinder 15, and the air inlet end of the exhaust assembly 4 extends into the second through hole 152. Exemplarily, the first through hole 151 and the second through hole 152 are located on opposite sides of the side wall of the mounting cylinder 15, and the first through hole 151 and the second through hole 152 are directly opposite each other. When the explosion-proof lamp 2 is in operation, the heat it generates is relatively concentrated inside the mounting cylinder 15 compared to the first mounting cavity. When the air inlet assembly 3 is working, it brings in cool outdoor air into the first mounting cavity. When the exhaust assembly 4 is working, it extracts the hot air from the mounting cylinder 15. At this time, the cooler air in the first mounting cavity enters the interior of the mounting cylinder 15 through the first through hole 151. The above arrangement can achieve common heat dissipation between the first mounting cavity and the interior of the mounting cylinder 15. Because the space inside the mounting cylinder 15 is smaller than that inside the first mounting cavity, the airflow speed inside the mounting cylinder 15 is faster, enabling faster heat dissipation. The mounting cylinder 15 is connected to the first mounting cavity through the first through hole 151. During heat dissipation, this prevents excessive pressure inside the mounting cylinder 15 from causing the hot air generated by the explosion-proof lamp 2 to escape from the front cover 12 of the outer shell 1. When the light-emitting end 21 of the explosion-proof lamp 2 is sealed to the front cover 12, the above arrangement can prevent the seal between the light-emitting end 21 and the front cover 12 from failing.

[0067] In one embodiment, see Figure 2 , Figure 3 and Figure 7 As a specific embodiment of the explosion-proof lamp box for the fermentation room of the koji-making workshop provided in this application, the front cover 12 has an assembly hole 121 for the light-emitting end 21 of the explosion-proof lamp 2 to extend out. A sealing ring 16 is installed between the light-emitting end 21 of the explosion-proof lamp 2 and the assembly hole 121. It is easy to understand that the sealing ring 16 can be made of an elastic material such as rubber. When the light-emitting end 21 of the explosion-proof lamp 2 is located inside the sealing ring 16 and the assembly hole 121 is located outside the sealing ring 16, the light-emitting end 21 and the sealing ring 16 together compress the sealing ring 16, causing the sealing ring 16 to undergo elastic deformation. The elastic deformation of the sealing ring 16 serves to seal the light-emitting end 21 and the assembly hole 121.

[0068] In this structure, a sealing ring 16 is provided between the light-emitting end 21 and the mounting hole 121. The elastic deformation of the sealing ring 16 can seal the light-emitting end 21 and the mounting hole 121, preventing the hot gas generated by the explosion-proof lamp 2 from escaping from between the light-emitting end 21 and the mounting hole 121.

[0069] In one embodiment, see Figure 2 and Figure 7As a specific embodiment of the explosion-proof lighting box for the fermentation room in the koji-making workshop provided in this application, an annular groove 161 is formed on the outer peripheral surface of the sealing ring 16 for the edge of the assembly hole 121 to extend into. Indicatively, the sealing ring 16 can be formed as a single piece through a one-time molding process. After the sealing ring 16 is formed in the mold, an inwardly recessed annular groove 161 is formed on the outer peripheral surface of the sealing ring 16. When the edge of the assembly hole 121 extends into the interior of the annular groove 161, the opposite sides of the annular groove 161 can clamp the edge portion of the assembly hole 121. By forming the annular groove 161 on the outer peripheral surface of the sealing ring 16, the edge of the assembly hole 121 can be extended into the annular groove 161 during the assembly process, preventing the sealing ring 16 from falling off the assembly hole 121.

[0070] In one embodiment, see Figure 3 and Figure 4 As a specific embodiment of the explosion-proof lighting fixture box for the fermentation room in the koji-making workshop provided in this application, the air inlet assembly 3 includes an air inlet duct 31 and an air inlet fan 32. The air inlet fan 32 is mounted on the housing 11. The air inlet end of the air inlet duct 31 is connected to the air inlet fan 32, and the air outlet end of the air inlet duct 31 passes through the fixing plate 14 and extends into the first mounting cavity. The air inlet fan 32 is located in the second mounting cavity. One end of the air inlet fan 32 is fixed to the housing 11, and the end of the air inlet fan 32 away from the housing 11 is fixed to the air inlet end of the air inlet duct 31, ensuring the air intake efficiency of the air inlet fan 32. Exemplarily, fasteners can be used to fix both ends of the air inlet fan 32 to the housing 1 and the air inlet duct 31 respectively. Schematably, the air inlet duct 31 can be an approximate L-shaped structure, with one end of the L-shaped structure fixed to the air inlet fan 32, and the other end of the L-shaped structure passing through the fixing plate 14 and extending into the first mounting cavity.

[0071] Please see Figure 3 and Figure 5 The exhaust assembly 4 includes an exhaust duct 41 and an exhaust fan 42. The exhaust fan 42 is mounted on the housing 11. The air inlet end of the exhaust duct 41 communicates with the second through hole 152 of the mounting cylinder 15, and the air outlet end of the exhaust duct 41 passes through the fixing plate 14 and is connected to the exhaust fan 42. It is easy to understand that the exhaust fan 42 is also located within the second mounting cavity. One end of the exhaust fan 42 is fixed to the housing 11, and the end of the exhaust fan 42 away from the housing 11 is fixed to the air outlet end of the exhaust duct 41, ensuring the exhaust efficiency of the exhaust fan 42. For example, the exhaust duct 41 includes two bent sections. Specifically, after the air outlet end of the exhaust duct 41 is connected to the exhaust fan 42, it first bends towards the fixing plate 14, passes through the fixing plate 14, and then bends towards the mounting cylinder 15, so that the air inlet end of the exhaust duct 41 extends into the second through hole of the mounting cylinder 15.

[0072] In this embodiment, when the intake fan 32 rotates, it can bring cold outdoor air into the first mounting cavity; when the exhaust fan 42 rotates, it can exhaust hot air from the first mounting cavity.

[0073] In one embodiment, see Figure 3 As a specific embodiment of the explosion-proof lighting fixture box for the fermentation room of the koji-making workshop provided in this application, the explosion-proof lighting fixture box for the fermentation room of the koji-making workshop also includes a filter screen 5 and an air inlet grille 6. The air inlet grille 6 is installed on the side of the inlet fan 32 away from the air inlet duct 31, and the filter screen 5 is installed between the inlet fan 32 and the air inlet grille 6. In one possible implementation, both the filter screen 5 and the air inlet grille 6 are located on the outside of the outer shell 1. Fasteners can be used to sequentially pass through the air inlet grille 6, the filter screen 5, the outer shell 1, and the inlet fan 32 to fix the air inlet grille 6, the filter screen 5, the outer shell 1, and the inlet fan 32 together, and the replacement and disassembly of the filter screen 5 are relatively easy. It is easy to understand that when the inlet fan 32 is rotating, the air inlet grille 6 can prevent large particles of impurities from entering the outer shell 1 and affecting the normal operation of the inlet fan 32 and the explosion-proof lighting fixture 2, and the filter screen 5 can prevent dust from entering the outer shell 1 and affecting the normal operation of the inlet fan 32 and the explosion-proof lighting fixture 2.

[0074] In one embodiment, see Figure 2 and Figure 3 As a specific embodiment of the explosion-proof lighting fixture box for the fermentation room of the koji-making workshop provided in this application, the box also includes a conduit 7 through which the cable of the explosion-proof lighting fixture 2 passes. One end of the conduit 7 is connected to the explosion-proof lighting fixture 2, and the other end of the conduit 7 extends out of the outer shell 1. Specifically, the other end of the conduit 7 extends from the rear cover 13 of the outer shell 1. Exemplarily, the end of the conduit 7 facing the explosion-proof lighting fixture 2 is provided with an external thread, and the end of the explosion-proof lighting fixture 2 facing the rear cover 13 is provided with an internal threaded hole that is threadedly connected to the conduit 7. In one possible implementation, a galvanized steel pipe can be used as the conduit 7 to ensure its corrosion resistance. By providing the conduit, the cable of the explosion-proof lighting fixture can be led out to the outside of the outer shell.

[0075] In one embodiment, see Figure 2 and Figure 3As a specific embodiment of the explosion-proof lighting box for the fermentation room in the koji-making workshop provided in this application, a through hole 71 is provided on the side wall of the conduit 7. It should be noted that the through hole 71 is located inside the outer shell 1, and the cables of the inlet fan 32 and the exhaust fan 42 can extend into the conduit 7 through the through hole 71. There can be two through holes 71, which can be respectively located on opposite sides of the conduit 7. The cables of the inlet fan 32 and the exhaust fan 42 extend into the conduit 7 through their respective through holes 71. By providing through holes on the side wall of the conduit 7, the cables of the inlet fan 32 and the exhaust fan 42 can pass through the conduit 7 to the outside of the outer shell 1.

[0076] In one embodiment, as a specific implementation of the explosion-proof lighting box for the fermentation room in the koji-making workshop provided in this application, both the inner and outer surfaces of the outer shell 1 are coated with a corrosion-resistant and thermally conductive coating. Nano-composite ceramic coating can be used as the corrosion-resistant and thermally conductive coating. By coating the surface of the outer shell 1 with a corrosion-resistant and thermally conductive coating, the corrosion resistance of the outer shell 1 is improved, and the heat dissipation performance of the outer shell 1 is increased. When air flows inside the outer shell 1, the heat inside the outer shell 1 can be carried away more quickly, improving the heat dissipation efficiency of the explosion-proof lighting box for the fermentation room in the koji-making workshop.

[0077] Please see Figure 12 and Figure 13 The explosion-proof lighting box for the fermentation room in the koji-making workshop provided in this application can be embedded in the wall 8 of the fermentation room during use. The light-emitting end 21 of the explosion-proof device is located inside the fermentation room, while the intake fan 32 and exhaust fan 42 are exposed outside the fermentation room. When the wall 8 of the fermentation room is relatively thick, the intake fan 32 and exhaust fan 42 can be installed on the rear cover 13; when the wall 8 of the fermentation room is relatively thin, the intake fan 32 and exhaust fan 42 can be installed on the side wall of the housing 11.

[0078] In one embodiment, see Figures 1-3As a specific embodiment of the explosion-proof lighting box for the fermentation room in the koji-making workshop provided in this application, the edges of the front cover 12 and the rear cover 13 are respectively provided with flanges parallel to the side walls of the housing 11. Schematic, the front cover 12 includes a bottom wall and four flanges surrounding the bottom wall, and the rear cover 13 also includes a bottom wall and four flanges surrounding the bottom wall. The flanges of the front cover 12 and the rear cover 13 respectively cover the side walls of the housing 11. Specifically, after the flanges of the front cover 12 and the rear cover 13 respectively cover the side walls of the housing 11, fasteners can be used to fix the flanges of the front cover 12 to the side walls of the housing 11, and fasteners can be used to fix the flanges of the rear cover 13 to the side walls of the housing 11. The above arrangement can increase the sealing effect of the housing 1, preventing the heat generated by the explosion-proof lighting 2 from escaping from the gap between the housing 11 and the front cover 12 or the rear cover 13.

[0079] Based on the above embodiments, this application also provides an assembly method for assembling the explosion-proof lighting fixture box for the fermentation room of a koji-making workshop provided in any of the above embodiments. The assembly method includes:

[0080] Assemble the air intake assembly 3 and the air exhaust assembly 4 separately. Specifically, fasteners can be used to fasten the air intake fan 32 to the air intake end of the air intake duct 31, and fasteners can be used to fasten the air exhaust fan 42 to the air outlet end of the air exhaust duct 41.

[0081] Please see Figure 8 and Figure 9 The explosion-proof light fixture 2 is installed on the mounting plate 14, and the cable of the explosion-proof light fixture 2 is passed through the mounting plate 14. Fasteners can be used to install the explosion-proof light fixture 2 on the mounting plate 14. After the explosion-proof light fixture 2 is assembled with the mounting plate 14, a conduit 7 can be installed on the explosion-proof light fixture 2, and the cable of the explosion-proof light fixture 2 passes through the mounting plate 14 and is run through the conduit 7.

[0082] Please see Figure 10 The air inlet assembly 3 and the air outlet assembly 4 are respectively installed on the fixing plate 14, and the air inlet assembly 3, the air outlet assembly 4, the explosion-proof lamp 2 and the fixing plate 14 are combined to form an assembly. Specifically, the air outlet end of the air inlet assembly 3 passes through the fixing plate 14 so that the air outlet end of the air inlet assembly 3 and the mounting cylinder 15 are located on the same side of the fixing plate 14, and the air inlet end of the exhaust assembly 4 passes through the fixing plate 14 and extends into the second through hole of the mounting cylinder 15.

[0083] Please see Figure 11The assembly is installed in a predetermined position within the housing 11. The air inlet end of the air inlet assembly 3 is installed on the housing 11, and the air outlet end of the exhaust assembly 4 is installed on the housing 11. For example, a limiting block can be installed inside the housing 11, with the fixing plate 14 of the assembly abutting against the limiting block. There can be four limiting blocks, each positioned at one of the four corners of the housing 11. The limiting blocks prevent the assembly from being inserted too deeply into the housing 11, thus avoiding interference with the lighting in the fermentation chamber. After the assembly is installed in the housing 11, fasteners can be used to secure the exhaust fan 42 to the housing 11, and fasteners can be used to secure the air inlet fan 32, the housing 11, the filter 5, and the air inlet grille 6.

[0084] The front cover 12 and the rear cover 13 are respectively placed on both ends of the housing 11, with the light-emitting end of the explosion-proof lamp 2 extending out of the front cover 12. Before placing the front cover 12 and the rear cover 13, the cables for the inlet fan 32 and the exhaust fan 42 are respectively inserted into the conduit 7 through the through hole 71. The sealing ring 16 is fixed to the front cover 12 by inserting the edge of the mounting hole 121 into the annular groove 161 on the outer circumference of the sealing ring 16. After the front cover 12 and the rear cover 13 are placed on the housing 11, fasteners can be used to fix the housing 11 to the front cover 12 and the rear cover 13 respectively.

[0085] The above assembly method can ensure the structural stability of the explosion-proof lighting box for the fermentation room in the koji-making workshop. At the same time, the assembly process of the explosion-proof lighting box for the fermentation room in the koji-making workshop is relatively easy, which is conducive to improving the production efficiency of the explosion-proof lighting box for the fermentation room in the koji-making workshop.

[0086] The above are merely optional embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
