Description

Technical Field

[0001] This invention relates to the field of air disinfection technology for edible mushroom inoculation rooms, and specifically to an ozone air disinfection machine for edible mushroom inoculation rooms. Background Technology

[0002] The inoculation of edible fungi requires a sterile environment, so the inoculation room must be air-sterilized to achieve a suitable level of biological cleanliness for inoculation. Currently, there are roughly three methods for disinfecting inoculation rooms in China: ultraviolet (UV) sterilization, chemical disinfection, and ozone disinfection. Comparing these three methods, UV lamps are affected by factors such as light distance, humidity, and light intensity reduction, making it difficult to guarantee stable disinfection results; chemical disinfection requires a high degree of indoor airtightness and is harmful to human health; ozone is generated on-site by an ozone generator, and its strong oxidizing effect causes various components in microbial cells to react, resulting in irreversible changes and death. Therefore, ozone sterilization machines are used for disinfection in edible fungi inoculation rooms.

[0003] Existing ozone sterilizers generate and release large amounts of ozone into the edible mushroom inoculation room. Due to the large molecular weight of ozone, it sinks, resulting in a higher ozone concentration in the lower layer than in the upper layer during the sterilization process. For edible mushroom inoculation rooms that require multi-layer sterilization, the upper layer ozone sterilization effect is lower than the lower layer sterilization effect. The gas circulation sterilization efficiency is low, and people need to wait for the ozone to naturally decay and decompose into oxygen before they can enter the edible mushroom inoculation room, which affects the inoculation progress.

[0004] In view of the above, in order to overcome the above technical problems, the present invention designs an ozone air sterilizer for edible fungi inoculation rooms, which solves the above technical problems. Summary of the Invention

[0005] The technical objective of this invention is to balance the ozone concentration difference between the upper and lower spaces in the inoculation room during the disinfection process, accelerate the ozone and air circulation rate, improve the disinfection efficiency of the upper layer, and reduce the waiting time for the ozone concentration in the room to decrease after disinfection.

[0006] To achieve the above-mentioned technical objectives, the present invention provides the following technical solution:

[0007] This invention provides an ozone air sterilizer for an edible fungus inoculation room, comprising a housing, a telescopic support, a fixing block, a sliding groove, and a chamber cover. The housing is equipped with the telescopic support, the fixing block, and the chamber cover. The fixing block has a sliding groove for the chamber cover to slide. The sliding groove on one side of the fixing block also includes a generation and reduction mechanism and a circulation mechanism. The generation and reduction mechanism is fixedly installed inside the housing. This mechanism ionizes and heats a portion of the flowing air through a processing chamber, causing the treated gas to be discharged at a high angle through an exhaust port, thereby controlling the rapid rise and fall of ozone concentration in the inoculation room. The circulation mechanism, by opening and closing the chamber cover, achieves three working states: ozone generation, circulating disinfection, and ozone reduction. Air circulation efficiency is improved through an air chamber and a guide groove. Air in the edible fungus inoculation room quickly enters the generation and reduction mechanism through the circulation mechanism for rapid exchange, thereby shortening the disinfection time.

[0008] The reduction mechanism further includes a processing chamber, an ionization plate, a heating element, and an exhaust port. The processing chamber is arranged in a ring array within the housing. The ring array distribution structure allows gas entering the circulating gas chamber to quickly enter the processing chamber through the vents and balances the impact stress of the gas within the chamber. The horizontal cross-sectional shape of the processing chamber is fan-shaped. The small-radius arc surface of the fan-shaped chamber is the inlet wall, and the large-radius arc surface is the exhaust wall. The small-radius arc surface of the fan-shaped chamber allows the gas to flow rapidly towards the large-radius arc surface after entering the processing chamber, thereby accelerating its entry into the processing chamber for ozone reduction and subsequent discharge. The ionization plate is fixedly installed on the chord edge of the fan-shaped processing chamber. The space between the ionization plate and the inlet wall is the inlet layer. The lower end of the ionization plate is connected to the processing chamber. The lower wall of the chamber forms a gas sedimentation layer. The gas flows from the circulation mechanism into the inlet layer, then through the gas sedimentation layer, and finally to the ionization plate in a U-shaped trajectory. This U-shaped trajectory ensures that the oxygen to be ionized is fully ionized after passing through the ionization plate. The heating resistance wire is fixedly installed between the ionization plates. After ozone generation and circulation disinfection are completed, the ionization plate stops ionizing, and the ozone is accelerated to enter the ozone reduction working state by heating the resistance wire. One end of the exhaust hole is fixedly installed on the exhaust wall on one side of the treatment chamber, and the other end of the exhaust hole is fixedly installed on the housing. The treatment chamber can both generate and reduce ozone. The exhaust hole discharges the gas treated by the generation and reduction mechanism into the edible fungus inoculation chamber.

[0009] The horizontal cross-sectional shape of the ionization plate is an arc shape that matches the fan-shaped processing cavity. The curvature of the arc is consistent with the curvature of the processing cavity. The two ionization plates have the same angle but different radii. The arc-shaped structure fits snugly with the fan-shaped structure of the processing cavity, and the presence of the arc-shaped ionization plate increases the surface area of ​​ionized oxygen, thus ensuring sufficient contact with the oxygen entering the processing cavity. Due to the different radii of the two ionization plates, the ionized oxygen is affected by different electric field strengths when passing through the ionization plates, increasing the number of oxygen ions released during ionization and thus improving the efficiency of ozone generation. The upper end of the ionization plate is connected to the... The upper wall of the treatment chamber is fixed in place to prevent gas from being discharged directly without ionization by the ionization plate. The lower end of the ionization plate and the lower wall of the treatment chamber form the gas sedimentation layer, which allows oxygen entering the reduction mechanism to be fully ionized to form ozone before settling and being discharged. The ionization plate and the air inlet wall of the treatment chamber form the air inlet layer, which allows the air outlet to quickly deliver gas to the treatment chamber. The space between the ionization plate and the exhaust wall forms the exhaust layer, which allows oxygen entering the reduction mechanism to be fully ionized to form ozone before being discharged through the exhaust port, thereby generating a large amount of ozone required for the disinfection process.

[0010] The heating resistance wires are arranged in a linear array with a sparse upper section and a dense lower section in the vertical direction. Since the high-temperature reduction mainly targets the ozone that sinks in the processing chamber, the resistance wires at the bottom of the processing chamber are more densely distributed. On the upper surface of the processing chamber, they are arranged in a local ring shape consistent with the arc-shaped bending direction of the ionization plate. The local ring shape on the processing chamber is consistent with the fan-shaped structure of the processing chamber, which reduces the dead angle of the heat radiation range in the processing chamber, allowing the gas to be fully heated and reduced. The heating temperature of the heating resistance wires is controlled within 50-100 degrees Celsius. Ozone itself is unstable and easily decays and is reduced to oxygen, especially above 50 degrees Celsius, where decay and reduction are rapid. Below 100 degrees Celsius, the generation of water vapor at high temperatures is avoided. The sparse upper section and dense lower section structure and temperature control improve the ozone reduction rate of the reduction mechanism and reduce the impact of high temperature on various components and the edible fungus inoculation chamber.

[0011] The exhaust port has a "Y"-shaped structure. The "Y" shape splits the gas after treatment in the processing chamber into two streams before exiting into the edible mushroom inoculation chamber, resulting in superior impact resistance and service life. The upper end of the "Y" is the diversion port connected to the casing. The channel design of this diversion port lengthens the gas flow path and increases the contact area, resulting in relatively slow changes in gas velocity, reducing gas impact and eddy current generation, thereby reducing noise and vibration. The lower end of the "Y" is the exhaust port connected to the exhaust wall. The included angle of the diversion port is obtuse. Gas flow through the obtuse-angled diversion port experiences some resistance, reducing gas velocity and pressure in the pipe, thus lowering the overall pressure loss of the exhaust system and improving system efficiency. The "Y"-shaped pipe structure ensures that the gas treated by the reduction mechanism maintains a stable flow state during exhaust, improving the stability and reliability of the reduction mechanism.

[0012] The diversion port is located at one-sixth of the side of the box body, allowing the gas to be discharged into the inoculation chamber at a higher height. The exhaust port is located at one-sixth of the exhaust wall, allowing the sinking ozone to rise and be discharged, thus improving the purity of the discharged ozone. The treated gas is discharged into the edible fungus inoculation chamber at a higher height. The exhaust port is inclined at 60°-90° to the horizontal plane, allowing the treated gas to be discharged obliquely upward at a higher height. Under the action of the gas molecules in the chamber, the discharged gas quickly and evenly fills the edible fungus inoculation chamber. The ozone generated by the ionization plate and deposited in the gas precipitation layer is continuously generated and rises and is discharged. In conjunction with the fan-shaped linear array distribution of the heating resistance wire with a sparse upper and dense lower section, the oxygen generated after reduction is quickly discharged, realizing the rapid discharge of gas in the reduction mechanism.

[0013] The circulation mechanism further includes an air inlet, a ventilation fan, an air chamber, a guide channel, and vents. The air inlet is located at the bottom of the housing, and the ventilation fan is fixedly installed above the air inlet. The air chamber is fixedly installed above the ventilation fan. The cross-sectional shape of the air chamber is an isosceles trapezoid, which restricts the gas movement path by the inclined plane, thereby accelerating the gas flow within the air chamber. The air inlet is located at the lower end of the air chamber. The air inlet is the same size as the air inlet and is vertically connected, thereby reducing gas diffusion and loss before entering the air chamber. The air outlet is located at the upper end of the air chamber. The air outlet can be closed by the chamber cover, so that the air chamber is in a sealed state during ozone generation and ozone reduction. During the circulation disinfection process, the air chamber is opened. The guide channel is located inside the air chamber, and multiple vents are located within the guide channel. A processing chamber is installed at the other end of the vents. The upwardly radially tapering cylindrical structure of the air inlet accelerates the airflow entering the circulation mechanism.

[0014] The air inlet is an arc-shaped groove that runs vertically through the air chamber and gradually narrows towards the air inlet. The arc-shaped groove structure gradually narrows and concaves towards the air inlet, allowing the gas to be drawn into the groove by the ventilation fan through the large-radius arc opening. The upper and lower ends of the arc-shaped groove are circular through holes of different sizes, with the radius of the upper end being larger than that of the lower end. When the gas passes through the arc-shaped groove, the curved shape can change the direction of gas flow, causing the gas to bend within the air inlet. As the bending path becomes smaller, the gas movement speed is accelerated. The structure of the groove causes the gas to be compressed, reducing its volume and increasing its density, thereby increasing the gas flow velocity within the air inlet and improving the working efficiency of the circulation mechanism.

[0015] The guide groove is a spiral structure surrounding the air cavity with equal pitch. The equal pitch allows the vent holes to be evenly opened on the guide groove. The spiral groove cooperates with the radial narrowing structure of the air cavity to concentrate the impact of the gas in the groove. The spiral guide groove can guide the gas in the air cavity, thereby reducing the vibration caused by the gas impact when the circulation mechanism is working.

[0016] The vent is opened along the axial direction of the inner surface of the guide groove, so that the gas guided by the guide groove is concentrated into the vent and accelerated to be discharged. The end of the vent near the air chamber is the vent, and the end of the vent near the processing chamber is the air outlet. The vent is a through hole with a radially decreasing diameter from the vent to the air outlet. The radially decreasing structure can control the direction and speed of air flow. The large structure of the vent increases the gas throughput and reduces the gas retention in the air chamber. The small structure of the air outlet concentrates the gas flow stress and reduces gas diffusion, so that the gas entering the circulation mechanism quickly passes through the vent and quickly enters the reduction mechanism.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. By setting up a reduction mechanism and a circulation mechanism, the present invention accelerates the circulation rate of ozone with the air in the inoculation room and the reduction of ozone after disinfection, thereby reducing the ozone concentration difference between the upper and lower spaces during disinfection and stabilizing and improving the disinfection effect of the upper space, improving the efficiency of circulating disinfection and allowing humans to enter the inoculation room for inoculation more quickly after disinfection.

[0019] 2. This invention, through the setting of a reduction generation mechanism, accelerates the entry of gas into the gas chamber by the fan-shaped processing chamber distributed in a ring array, and the locally ring-distributed ionization plates ensure that the gas entering the processing chamber is fully ionized to form ozone. The electric heating resistance wire with a sparse upper section and a dense lower section accelerates the rate at which ozone is reduced to oxygen. The upwardly inclined "Y"-shaped exhaust pipe ensures that the gas discharged from the reduction generation mechanism fills the edible fungus inoculation chamber more evenly and quickly, thus ensuring the ozone generation rate while accelerating the emission of ozone required during the disinfection process.

[0020] 3. By setting up a circulation mechanism, the air inlet with an arc-shaped groove accelerates the air intake rate, the design of the guide groove forms a spiral upward gas impact, and the design of the vent with a large inlet and a small outlet allows the gas to enter the processing chamber quickly, so that the gas in the edible fungus inoculation chamber circulates rapidly.

Detailed Implementation

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] like Figures 1 to 9 As shown, an ozone air sterilizer for edible mushroom inoculation rooms allows the sterilization time to be set based on the room's space and the amount of inoculum cells. After sterilization, ozone generation stops, and ozone reduction begins. It is easy to use and includes a housing 1, a telescopic support 2, a fixing block 3, and a chamber cover 4. The housing 1 is equipped with the telescopic support 2, the fixing block 3, and the chamber cover 4. The fixing block 3 has a sliding groove 31 for the chamber cover 4 to slide. The telescopic support 2 is used to adjust the height of the housing 1 according to the size of the inoculation room. It also includes a generation and reduction mechanism 5 and a circulation mechanism 6. Mechanism 5 is fixedly installed inside the housing 1. The ozone generation and reduction mechanism 5 ionizes and heats a portion of the flowing air through the processing chamber 51, causing the treated gas to be discharged at a high angle through the exhaust port 542, thereby controlling the rapid rise and fall of ozone concentration in the inoculation chamber. The circulation mechanism 6 relies on the opening and closing chamber cover 4 to realize three working states: ozone generation, circulating disinfection, and ozone reduction. The air circulation efficiency is improved through the air chamber 63 and the guide channel 64. The air in the edible fungus inoculation chamber quickly enters the ozone generation and reduction mechanism 5 through the circulation mechanism 6 to achieve rapid exchange, thereby shortening the disinfection time.

[0035] like Figure 2 , Figure 3 and Figure 5As shown, the ozone generation and reduction mechanism 5 also includes a processing chamber 51, an ionization plate 52, a heating wire 53, and an exhaust port 54. The fan-shaped processing chamber 51 is arranged in a ring array within the housing 1. The ring array distribution structure allows gas entering the circulating gas chamber 63 to quickly enter the processing chamber 51 through the ventilation port and balances the impact stress of the gas within the chamber 63. The horizontal cross-sectional shape of the processing chamber 51 is fan-shaped. The small-radius arc surface of the fan-shaped chamber is the inlet wall 511, and the large-radius arc surface is the exhaust wall 512. The small-radius arc surface of the fan-shaped chamber allows the gas to flow rapidly towards the large-radius arc surface after entering the processing chamber 51, thereby accelerating its entry into the processing chamber 51 for ozone generation and reduction before discharge. The ionization plate 52 is fixedly installed on the chord edge of the fan-shaped processing chamber 51. The space between the ionization plate 52 and the inlet wall 511 is the inlet layer 521, and the space between the lower end of the ionization plate 52 and the lower wall of the processing chamber 51 is the gas sedimentation layer. The gas deposition layer 522 causes the gas flow trajectory from the circulation mechanism 6 into the air intake layer 521, then through the gas deposition layer 522 to the ionization plate 52 to form a "U" shape. The "U" shaped gas movement trajectory ensures that the oxygen drawn in by the circulation mechanism 6 enters the treatment chamber 51 and is fully ionized after passing through the ionization plate 52. An electric heating resistance wire 53 is fixedly installed between the ionization plates 52. When ozone generation and circulation disinfection are completed, the ionization plate 52 stops ionizing. The ozone in the edible fungus inoculation chamber is drawn into the treatment chamber 51 through the circulation mechanism 6 and is heated and accelerated by the resistance wire 53, thus entering the ozone reduction working state. One end of the exhaust port 54 is fixedly installed on one side of the treatment chamber 51, and the other end of the exhaust port 54 is fixedly installed on the box body 1. The treatment chamber 51 can both generate and reduce ozone. The exhaust port 54 discharges the gas drawn in by the circulation mechanism 6 into the edible fungus inoculation chamber after being processed by the generation and reduction mechanism 5.

[0036] like Figure 3 and Figure 4As shown, the horizontal cross-sectional shape of the ionization plate is an arc shape that matches the fan-shaped processing cavity. The curvature of the arc is consistent with the curvature of the processing cavity. The two ionization plates 52 have the same angle but different radii. The arc-shaped structure fits the fan-shaped structure of the processing cavity 51, and the presence of the arc-shaped ionization plates 52 can increase the surface area of ​​ionized oxygen, thereby ensuring sufficient contact with the oxygen entering the processing cavity 51. Due to the different radii of the two ionization plates 52, the ionized oxygen will be affected by different electric field strengths when passing through the ionization plates, increasing the number of oxygen ions released during ionization, thereby improving the efficiency of ozone generation. The radius of the arc surface is equal to the radius of the fan-shaped arc of the processing cavity 51. The insulation between the two electrodes is air. When the voltage between the two electrodes rises to a certain level, the air is broken down, and at this time the oxygen... Ozone is generated by the ionization of gas molecules. The upper end of the ionization plate 52 is attached and fixed to the upper wall of the treatment chamber 51 to prevent the gas from being discharged directly without the ionization effect of the ionization plate 52. The lower end of the ionization plate 52 and the lower wall of the treatment chamber 51 form the gas precipitation layer 522, so that the oxygen entering the reduction mechanism 5 is fully ionized to form ozone before being discharged. The air inlet wall 511 of the ionization plate 52 and the treatment chamber 51 forms the air inlet layer 521, so that the air outlet 652 can quickly send the gas in the gas chamber 63 to the treatment chamber 51. The space between the ionization plate 52 and the exhaust wall 512 forms the exhaust layer 523, so that the oxygen entering the reduction mechanism 5 is fully ionized to form ozone and then discharged through the exhaust hole 54, thereby producing a large amount of ozone required for the disinfection process.

[0037] like Figure 4 and Figure 5 As shown, the heating resistance wires 53 are arranged in a linear array with a sparse upper section and a dense lower section in the vertical direction, and in a local ring-shaped distribution in the horizontal direction. Since the high-temperature reduction mainly involves the ozone that sinks in the processing chamber 51, the heating resistance wires 53 at the bottom of the processing chamber 51 are more densely distributed. On the upper surface of the processing chamber, they are arranged in a local ring-shaped distribution consistent with the arc-shaped bending direction of the ionization plate. The local ring-shaped distribution on the processing chamber is consistent with the fan-shaped structure of the processing chamber, which reduces the dead angle of the heat radiation range in the processing chamber, so that the gas is fully heated and reduced. During the growth stage of most edible fungi mycelia in the inoculation chamber, the room temperature is best controlled at 25±1℃. Therefore, the heating temperature of the heating resistance wires 53 is controlled within 50-100 degrees Celsius. Ozone itself is unstable and easily decays and is reduced to oxygen, especially above 50 degrees Celsius, where decay and reduction are rapid. Below 100 degrees Celsius, the generation of water vapor at high temperature is avoided. The sparse upper section and dense lower section structure and temperature control improve the reduction rate of ozone generated by the reduction mechanism 5 and reduce the impact of high temperature on various components and the temperature in the edible fungi inoculation chamber.

[0038] like Figure 1 , Figure 2 and Figure 3As shown, the exhaust port 54 has a "Y"-shaped structure. The "Y" shape means that the gas processed in the treatment chamber is discharged into the edible fungus inoculation chamber in a two-way split, resulting in better impact resistance and service life. The upper end of the "Y" shape is the diversion port 541 connected to the box body 1. The channel design of the diversion port 541 lengthens the gas flow path and increases the contact area, making the gas velocity change relatively slowly, reducing gas impact and eddy current generation, thereby reducing noise and vibration. The lower end of the "Y" shape is the exhaust port 542 connected to the exhaust wall 512. The included angle of the diversion port 541 is an obtuse angle. The gas will encounter certain resistance during the flow process in the obtuse angle diversion port, thereby reducing the gas velocity and pressure in the pipeline, thus reducing the overall pressure loss of the exhaust system and improving the system efficiency. The "Y"-shaped pipeline structure ensures that the gas processed by the reduction mechanism 5 maintains a stable flow state during the exhaust process, improving the stability and reliability of the reduction mechanism 5.

[0039] like Figure 3 As shown, the diversion port 541 is located at one-sixth of the height of the housing 1, allowing the discharged gas to be rapidly distributed in the inoculation chamber at a higher height. The exhaust port 542 is located at one-sixth of the height of the exhaust wall 512, allowing the sinking ozone to rise and be discharged, thus improving the purity of the ozone discharge. The treated gas is discharged into the edible fungus inoculation chamber at a higher height and is inclined at 60°-90° to the horizontal plane, allowing the treated gas to be discharged obliquely upward at a higher height. Thus, under the action of the gas molecules in the chamber, the discharged gas quickly and evenly fills the edible fungus inoculation chamber. The ozone generated by the ionization plate 52 and deposited in the gas precipitation layer 522 is continuously generated and rises and is discharged. In conjunction with the fan-shaped linear array distribution of the heating resistance wire 53 (sparse on top and dense on the bottom), the oxygen generated after reduction is quickly discharged, realizing the rapid discharge of gas in the reduction mechanism 5.

[0040] like Figure 2 and Figure 6As shown, the circulation mechanism 6 further includes an air inlet 61, a ventilation fan 62, an air chamber 63, a guide channel 64, and ventilation holes. The air inlet 61 is located at the bottom of the housing 1. The ventilation fan 62 is fixedly installed on the air inlet 61. The air chamber 63 is fixedly installed above the ventilation fan 62. The cross-sectional shape of the air chamber 63 is an isosceles trapezoid, which restricts the movement path of the gas by the inclined plane. The air inlet 631 is located at the lower end of the air chamber 63. The air inlet 631 is the same size as the air inlet 61 and is vertically connected, thereby reducing the gas flow rate. The air cavity 63 diffuses outwards, and the air outlet 632 is provided at the upper end of the air cavity 63. The air outlet 632 can be closed by the cavity cover 4, so that the air cavity 63 is in a sealed state during ozone generation and ozone reduction. During the circulation disinfection process, the air cavity 63 is opened. The air guide groove 64 is provided in the air cavity 63, and multiple ventilation holes 65 are provided in the air guide groove 64. The processing cavity 51 is fixedly installed at the other end of the ventilation hole 65. The upward radially tapering cylindrical structure of the air inlet 61 accelerates the airflow into the circulation mechanism 6.

[0041] like Figure 6 As shown, the air inlet 61 is an arc-shaped groove that runs vertically through the air chamber 63 and gradually narrows towards the air inlet 631. The arc-shaped groove structure gradually narrows and concaves towards the air inlet 631. The upper and lower ends of the arc-shaped groove are circular through holes of different sizes, with the radius of the upper end being smaller than that of the lower end. The gas is drawn into the groove by the ventilation fan 62 through the large-radius arc opening. When the gas passes through the arc-shaped groove, the curved shape can change the direction of gas flow, causing the gas to bend within the air inlet 61. Due to the change in the bending path, the gas is subjected to centrifugal force within the arc-shaped groove, thereby accelerating the gas's movement speed. The structure of the groove causes the gas to be compressed, reducing its volume and increasing its density, thus increasing the gas flow velocity within the air inlet 61 and improving the working efficiency of the circulation mechanism 6.

[0042] like Figure 2 and Figure 6 As shown, the guide groove 64 is a spiral structure surrounding the air cavity 63 with equal pitch, so that the gas entering the air cavity 63 rises spirally within the air cavity 63. The spiral groove cooperates with the radially reduced cylindrical structure of the air cavity 63 to concentrate the impact of the gas in the groove. The spiral guide groove 64 can guide the gas in the air cavity 63. The equal pitch allows the vent holes 65 to be evenly opened on the guide groove 64, thereby reducing the vibration caused by gas collision when the circulation mechanism 6 is working.

[0043] like Figure 6As shown, the vent 65 is opened along the axial direction of the inner surface of the guide groove 64, so that the gas guided by the guide groove 64 is concentrated into the vent 65 and accelerated for discharge. The end of the vent 65 near the air chamber is the vent 651, and the end of the vent 651 near the processing chamber 51 is the air outlet 652. The vent 65 is a through hole with a radially decreasing diameter from the vent 651 to the air outlet 652. The radial structure can control the airflow direction and speed. The large structure of the vent 65 increases the gas throughput and reduces the gas retention in the air chamber 63. The small structure of the air outlet 652 concentrates the gas flow stress and reduces gas diffusion, so that the gas entering the circulation mechanism quickly passes through the vent 65 and quickly enters the reduction mechanism. The vent 65 causes the spiraling gas to concentrate stress and enter the processing chamber 51 through multiple vent 65s, so that the gas entering the circulation mechanism 6 quickly passes through the vent 65 and quickly enters the reduction mechanism 5.

[0044] like Figure 7 As shown, during ozone generation, oxygen enters the air chamber 63 through the air inlet 61 and spirals upward under the guidance of the guide channel 64. At this time, the chamber cover 4 is closed, and the oxygen is accelerated into the processing chamber 51 through multiple ventilation holes 65 on the guide channel 64. The ionization plates 52 on both sides of the processing chamber 51 discharge, ionizing the oxygen passing between the ionization plates 52 into ozone that sinks. The ozone is discharged obliquely upward outside the box 1 through the "Y"-shaped exhaust hole 54 that accumulates and rises to the top after continuous generation, filling the edible fungus inoculation chamber for disinfection.

[0045] like Figure 8 As shown, during the cyclic disinfection process, oxygen enters the air chamber 63 through the air inlet 61 and spirals upward under the guidance of the guide channel 64. At this time, the chamber cover 4 is opened, and part of the oxygen returns to the inoculation chamber through the air outlet 632. The other part of the gas enters the processing chamber 51 through the multiple ventilation holes 65 opened on the guide channel 64. Through ionization, the generated ozone is discharged obliquely upward to the outside of the box 1 through the "Y"-shaped exhaust hole 54 and circulated for disinfection in the edible fungus inoculation chamber.

[0046] like Figure 9 As shown, during the ozone reduction process, a large amount of ozone generated during the disinfection of the edible fungus inoculation chamber is re-entered into the treatment chamber 51 through the circulation mechanism 6. At this time, the chamber cover 4 is closed, and the ozone is reduced to oxygen by the high temperature of the electric heating wire 53. Then, it is discharged into the edible fungus inoculation chamber through the "Y"-shaped exhaust hole 54, so that the ozone concentration in the edible fungus inoculation chamber returns to the normal state.

[0047] During operation, the gas is drawn into the air chamber 63 in large quantities by the ventilation fan 62 through the arc-shaped air inlet 61, undergoing three working states: ozone generation, circulating disinfection, and ozone reduction. Under the action of the guide channel 64 opened within the air chamber 63, the gas rises in a spiral shape and impacts within the guide channel 64. Multiple vents 65 on the guide channel 64 concentrate the impact stress of the gas within the guide channel 64. The gas then accelerates through the vents 65 into the processing chamber 51. The ionization plates 52 on both sides of the processing chamber 51 discharge, ionizing the oxygen in the gas passing between the ionization plates 52 into ozone, which then sinks. The ozone continuously accumulates and rises to the upper "…". The Y-shaped exhaust port 54 discharges ozone diagonally upwards and outwards from the casing 1, filling the mushroom inoculation chamber and completing the ozone generation disinfection process. When the ozone concentration in the mushroom inoculation chamber reaches the required concentration for disinfection, the chamber cover 4 is opened to allow some of the air entering the air chamber 63 to be discharged for circulation disinfection. After disinfection, a large amount of ozone from the mushroom inoculation chamber is re-entered into the treatment chamber 51 through the circulation mechanism 6. After being heated at high temperature by the electric heating wire 53, the ozone is reduced to oxygen and discharged back into the mushroom inoculation chamber through the Y-shaped exhaust port 54, restoring the ozone concentration in the mushroom inoculation chamber to a normal state and completing the entire process of ozone air disinfection in the mushroom inoculation chamber.
