Description

Technical Field

[0001] The invention relates to a disinfection device, in particular to a disinfection cabinet with a drying function. Background Art

[0002] The disinfection cabinet is a commonly used electrical product, and generally a heating component is provided inside it to achieve disinfection. Since the internal air expands due to heat, the disinfection cabinet is usually provided with a vent connected to the outside to discharge hot air and safely and effectively control the internal pressure. Since some items to be disinfected may contain moisture, the moisture will vaporize during the operation of the disinfection cabinet, and the humidity inside the disinfection cabinet will increase. In order to speed up the drying effect, dehumidification is achieved by introducing external air. Specifically: an air supply duct connected to the outside is provided in the disinfection cabinet, and an air valve and a fan are provided in the air supply duct. When it is necessary to dehumidify the interior of the disinfection cabinet, the operator opens the air valve, hoping to introduce external air into the disinfection cabinet to alleviate the humidity. However, this method will have the following problems in implementation: after the external air enters the disinfection cabinet, its mixing effect is not urgent, resulting in uneven humidity inside the disinfection cabinet and low drying efficiency; at the same time When it is operated manually, the degree of automation is low and there is a certain hysteresis. After the air valve is opened, the operator tends to forget to close it, which makes the humidity in the disinfection cabinet unstable. When the humidity of the external air is higher than that of the internal air, the air valve is still opened for air replenishment, and the humidity inside the disinfection cabinet will continue to rise, which has a counterproductive effect. If the external air is directly replenished into the interior of the disinfection cabinet, the temperature inside the disinfection cabinet will drop suddenly, reducing the disinfection efficiency of the disinfection cabinet. In addition, since the installation position of the heating component in the existing disinfection cabinet is relatively fixed, when the heating component is heated, it will cause the local temperature in the disinfection cabinet to be too high. Summary of the invention

[0003] The object of the present invention is to provide a disinfection cabinet with a drying function to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solutions adopted to achieve the above objectives are:

[0005] A disinfection cabinet with a drying function, comprising a cabinet body, an air guide channel, an air valve assembly and a fan, wherein the air guide channel is provided with an air guide inlet, an air guide outlet and an air supply inlet, wherein the air guide inlet and the air guide outlet are both connected to the interior of the cabinet body, and the air supply inlet is connected to the exterior of the cabinet body; the air valve assembly comprises an electrically controlled valve body, a first humidity sensor and a second humidity sensor, wherein the first humidity sensor is used to detect the external air humidity of the cabinet body, and the second humidity sensor is used to detect the internal air humidity of the cabinet body; the electrically controlled valve body comprises an electrically controlled driving element and a damper, wherein the electrically controlled driving element is electrically connected to the first humidity sensor and the second humidity sensor respectively, and the electrically controlled driving element is used to drive the damper to open or cut off the connection between the air supply inlet and the exterior of the cabinet body; the fan is used to drive air to flow in the air guide channel and the cabinet body.

[0006] This technical solution has at least the following beneficial effects: by providing an electronically controlled drive element, a damper, a first humidity sensor and a second humidity sensor, the electronically controlled drive element can control the operation of the damper according to data from the first humidity sensor and the second humidity sensor, thereby automatically adjusting the humidity in the cabinet. Generally, from the perspective of technicians in this technical field, using air with lower humidity to replace air with higher humidity is a conventional means of reducing humidity. Therefore, in actual operation, in order to reduce humidity, the following operation can be performed in combination with conventional control logic: when the second humidity sensor detects that the air humidity inside the cabinet rises to a set high value, and the air humidity outside the cabinet detected by the first humidity sensor is lower than the air humidity inside the cabinet detected by the second humidity sensor, the electronically controlled drive element drives the damper to open the connection between the air supply inlet and the outside of the cabinet. Under the action of the fan, the air outside the cabinet is supplied to the cabinet, and the air outside the cabinet is mixed with the humid air inside the cabinet. When the second humidity sensor detects that the air humidity inside the cabinet is lower than the set low value, or the air humidity outside the cabinet detected by the first humidity sensor is higher than the air humidity inside the cabinet detected by the second humidity sensor, the electronically controlled drive element drives the damper to cut off the connection between the air supply inlet and the outside of the cabinet, thereby realizing automatic opening and stopping of air supply, and effectively avoiding air supply when the air humidity outside the cabinet is still higher than the air humidity inside the cabinet. In addition, by providing an air guide channel and a fan, and arranging the air supplement inlet in the air guide channel, the internal and external air can be fully mixed when the external air is introduced, thereby improving the dehumidification efficiency.

[0007] It can be seen that the disinfection cabinet with drying function provided by the present invention, as a hardware architecture, can be utilized to perform automatic and effective drying operations.

[0008] As a further improvement of the above technical solution, the disinfection cabinet further includes a heating element, which is used to heat the air flowing through the air guide channel, and the air supply inlet is located on the air inlet side of the heating element. When replenishing air and reducing humidity, the external air is heated by the heating element in the process of flowing through the air guide channel, and the heated air is then replenished into the interior of the cabinet to avoid a sudden drop in temperature in the cabinet, so that the interior of the cabinet is kept within the disinfection temperature range; and the heating element heats the internal circulating airflow, so that the air in the cabinet is quickly and evenly heated.

[0009] As a further improvement of the above technical solution, the cabinet body includes a cabinet door, and the air guide inlet, air supply inlet, and air guide outlet are arranged on the side of the cabinet body facing the cabinet door, and the air guide inlet and air supply inlet are located above the air guide outlet. The cabinet door on the cabinet is generally arranged on the front side of the cabinet, and the air guide outlet is arranged on the rear side of the cabinet. The new air enters the cabinet from the air guide outlet, and the new air has a tendency to push the humid air inside the cabinet forward. When the user opens the cabinet door, the internal humid air will be discharged from the cabinet opening. Generally, the disinfection cabinet is provided with an exhaust pipe with a pressure relief exhaust function at the position of its cabinet door. After the new air is added, the pressure inside the cabinet will increase. At this time, the exhaust pipe is opened and the humid air can also be discharged from the exhaust pipe, which can effectively improve the dehumidification effect and efficiency; at the same time, considering the high density of humid air, the humid air will sink and gather at the lower part of the cabinet under the action of gravity. The air guide inlet and the air replenishment inlet are arranged above the air guide outlet. The internal circulating airflow flows from top to bottom in the air guide channel, and the internal circulating airflow flows from bottom to top in the cabinet, thereby driving the humid air to flow from bottom to top, so that the humid air and the new air outside are mixed more fully, so that the air inside the cabinet can be quickly and evenly dehumidified.

[0010] As a further improvement of the above technical solution, an air guide body is arranged in the cabinet, and the air guide body is in the shape of a tube body, and the air guide channel is formed in the air guide body and arranged along the length direction of the air guide body. The air guide body in the shape of a tube body, that is, the air guide body can be a square tube, a round tube or other irregular special-shaped tubes, as long as it is a semi-enclosed part with three ports communicating with each other, it can be regarded as a tube body, and the three ports are respectively an air guide inlet, an air supplement inlet, and an air guide outlet. Such an air guide body has the advantage of being easy to install, and because it is independent of the cabinet body, the air guide inlet, the air supplement inlet, and the air guide outlet can be freely designed, which is convenient for optimizing the air inlet and air outlet of the air guide body. In addition, the air guide body is further arranged in or inside the cabinet body.

[0011] As another improvement of the above technical solution, the air guide body is in the shape of a cover plate, and the air guide channel is formed between the air guide body and a side wall of the cabinet. The cover plate-shaped air guide body refers to an air guide body that is roughly in the shape of a thin-walled sheet metal, including a flat plate, a curved plate, a semi-enclosed shell, and a form with or without holes. In short, the air guide body only serves as a part of the channel wall of the air guide channel, and the rest of the channel wall is composed of the side wall of the cabinet. The above technical improvement solution of the cover plate-shaped air guide body is easy to process and saves the material constituting the air guide channel.

[0012] As a further improvement of the above technical solution, a partial structure of the air guide body is in the shape of a tube, and the other partial structure of the air guide body is in the shape of a cover plate.

[0013] The disinfection cabinet also includes a ventilation body and a fixed air box which are arranged in the cabinet and connected to each other. The ventilation body, the fixed air box and the cabinet together constitute the air guide channel. The fan is installed in the fixed air box. The air guide inlet and the air supply inlet are arranged on the fixed air box and arranged on the negative pressure side of the fan. The ventilation body and the cabinet constitute the air guide outlet, and the air guide outlet is arranged on the positive pressure side of the fan. The fixed air box is mainly used to fix the fan and protect the fan. It also plays a role in collecting the air inlet of the air guide channel. Different fixed air boxes are designed according to different cabinets. In other embodiments, the fixed air box can adopt a split structure, which is convenient for cleaning the inside of the fixed air box and also convenient for the installation and disassembly of the fan. The ventilation body guides the air outlet of the air guide channel. Different ventilation bodies can be designed according to different internal circulations.

[0014] As a further improvement of the above technical solution, the electrically controlled valve body also includes a substrate and a rotating arm, a wind valve port is arranged on the substrate, the air supply inlet is connected with the outside of the cabinet through the wind valve port, one end of the rotating arm is connected with the wind gate, the wind gate covers the wind valve port, the rotating arm is rotatably mounted on the substrate through a rotating shaft, and the electrically controlled driving element can drive the other end of the rotating arm to swing around the rotating shaft, thereby driving the wind gate to open or close the wind valve port. When the electric control drive element drives the rotating arm to rotate, the rotating arm drives the damper to move, mainly creating a flow gap between the damper and the damper port to open the air supply inlet. For the damper movement, the damper can be flipped up toward the inner port or outer port of the damper port relative to the damper port, so that the air supply inlet is connected with the outside of the cabinet. At this time, the axis of the rotating shaft is perpendicular to the axis of the damper port. The damper can also move to the side of the damper port relative to the damper port. At this time, the axis of the rotating shaft is parallel to the axis of the damper port. The shape and size of the damper port match the shape and size of the damper, and can be circular, rectangular or other irregular shaped ports.

[0015] As a further improvement of the above technical solution, the electric control valve body further includes a reset elastic member, which can drive the damper to reset to a state of closing the damper port. The reset elastic member can keep the damper in a state of closing the damper port, improve the stability of the damper closing, and prevent the damper from shifting in a closed state, thereby causing air leakage at the damper port. The reset elastic member can be a spring or an elastic sheet, and the installation position of the reset elastic member needs to be determined according to the action of the damper.

[0016] As a further improvement of the above technical solution, the base plate is one of the side walls of the cabinet. In this case, the damper is directly mounted on the cabinet, which can save space.

[0017] As another improvement of the above technical solution, the air valve assembly also includes a valve body box installed on the side wall of the cabinet, the substrate is one of the side walls of the valve body box, the components of the electric control valve body are installed in the valve body box, an air supply port is provided on the side wall of the cabinet, the air supply inlet is connected to the air valve port through the air supply port, and a ventilating port connected to the outside of the cabinet is also provided on the valve body box. In this case, the rotating arm, air door, and electric control drive element on the air valve assembly can be arranged in the valve body box to form a whole, which is convenient for maintenance and installation, and also prevents other objects from interfering with the movement of the air door. The valve body box can be directly fixed on the side wall of the cabinet.

[0018] As a further improvement of the above technical solution, a columnar fixing seat is installed in the valve body box, and a first detection hole and a second detection hole are respectively arranged at the positions where the side wall of the valve body box and the two ends of the fixing seat are in contact with each other. A detection port connected to the inside of the cabinet is arranged on the side wall of the cabinet, and the second detection hole is opposite to the detection port. The first humidity sensor and the second humidity sensor are respectively installed on the two ends of the fixing seat, and the first humidity sensor detects the external air humidity of the cabinet through the first detection hole, and the second humidity sensor detects the internal air humidity of the cabinet through the second detection hole and the detection port. The first humidity sensor and the second humidity sensor are installed on the fixing seat, which can modularize the air valve assembly, including a power module composed of an electric control valve body and a damper, and an induction detection module composed of the first humidity sensor, the second humidity sensor and the fixing seat. When performing maintenance, different modules can be installed and disassembled. Secondly, the setting of the fixing seat can prevent the first humidity sensor and the second humidity sensor from touching other components when detecting air humidity, which makes the humidity value of the detected air have a large error.

[0019] As a further improvement of the above technical solution, a first mounting groove and a second mounting groove are respectively provided on the two end surfaces of the fixing seat, the first humidity sensor is embedded and installed in the first mounting groove, and the second humidity sensor is embedded and installed in the second mounting groove, so that the first humidity sensor, the second humidity sensor and the fixing seat form an independent component, which can be installed and disassembled together on the valve body box. When disassembling for maintenance, the fixing seat can be directly removed without removing the valve body box. An isolation layer is hollowed out between the two ends of the fixing seat. The isolation layer mainly plays a role of moisture isolation to avoid mutual influence of humidity at the two ends of the fixing seat. It also plays a role of facilitating wiring. The wiring isolation layer of the first humidity sensor and the second humidity sensor passes through the isolation layer and is connected to the electronic control drive element.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Reference Figure 1 and Figure 4 A disinfection cabinet with a drying function, comprising: a cabinet 100, an air guide channel 130, an air valve assembly 500 and a fan 600, the air guide channel 130 is provided with an air guide inlet 200, an air guide outlet 300, and an air supplement inlet 400, the air guide inlet 200 and the air guide outlet 300 are both connected to the inside of the cabinet 100, and the air supplement inlet 400 is connected to the outside of the cabinet 100; the air valve assembly 500 includes an electric control valve body, a first humidity sensor 510 and a second humidity sensor 520, the first humidity sensor 510 is used to The external air humidity of the cabinet 100 is detected. The second humidity sensor 520 is used to detect the internal air humidity of the cabinet 100. The electric control valve body includes an electric control drive element 580 and a damper 530. The electric control drive element 580 is electrically connected to the first humidity sensor 510 and the second humidity sensor 520 respectively. The electric control drive element 580 is used to drive the damper 530 to open or cut off the connection between the air supply inlet 400 and the outside of the cabinet 100; the fan 600 is used to drive the air to flow in the air guide channel 130 and the cabinet 100.

[0032] When the second humidity sensor 520 detects that the air humidity inside the cabinet 100 rises to a set high value, and the air humidity outside the cabinet 100 detected by the first humidity sensor 510 is lower than the air humidity inside the cabinet 100 detected by the second humidity sensor 520, the electric control drive element 580 drives the damper 530 to open the connection between the air supply inlet 400 and the outside of the cabinet 100. Under the action of the fan 600, the air outside the cabinet 100 is supplied to the cabinet 100, and the air outside the cabinet 100 is mixed with the humid air inside the cabinet 100. At the same time, the air inside the cabinet 100 is ventilated through the air guide channel 130 and the inside of the cabinet 100. The air flows so that an orderly internal circulation airflow is formed in the cabinet 100, so that the humidity inside the cabinet 100 is uniform and the dehumidification efficiency is improved. When the second humidity sensor 520 detects that the air humidity inside the cabinet 100 is lower than the set low value, or the air humidity outside the cabinet 100 detected by the first humidity sensor 510 is higher than the air humidity inside the cabinet 100 detected by the second humidity sensor 520, the electronically controlled drive element 580 drives the damper 530 to cut off the connection between the air supply inlet 400 and the outside of the cabinet 100, effectively avoiding air supply when the air humidity outside the cabinet 100 is still higher than the air humidity inside the cabinet 100.

[0033] The disinfection cabinet further includes a heating element 700, which is used to heat the air flowing through the air guide channel 130. The air supplement inlet 400 is located on the air inlet side of the heating element 700. The heating element 700 can be installed in a variety of positions. The heating element 700 can be set beside the air guide inlet 200, beside the air guide outlet 300, and beside the air supplement inlet 400. Although the air flowing through the air guide channel 130 can be heated at each of the above positions, different installation positions have different effects. When the heating element 700 is set beside the air supplement inlet 400, the heating element 700 mainly heats the air supplemented from the outside, and the heated air is then supplemented into the interior of the cabinet 100 to avoid the temperature inside the cabinet 100. The sudden drop in temperature inside the cabinet 100 keeps the interior of the cabinet 100 within the disinfection temperature range; when the heating element 700 is arranged beside the air inlet 200, the heating element 700 mainly heats the circulating air inside the cabinet 100; when the heating element 700 is arranged beside the air outlet 300, the heating element 700 heats the supplementary air together with the air circulating inside the cabinet 100, and the heated mixed air then enters the cabinet 100, thereby avoiding a sudden drop in temperature inside the cabinet 100 and keeping the interior of the cabinet 100 within the disinfection temperature range.

[0034] There are many types of heating elements 700, and the heating element 700 is a PTC heating tube. The PTC heating tube is a modular structure with a heating element and a protective shell, which is more convenient to install. The heating component is an infrared quartz tube. The infrared quartz tube only has a heating structure and requires another protective structure to avoid direct contact, but the use cost is lower.

[0035] There are also many ways to install the heating element 700. In this embodiment, Figure 1 As shown, an installation opening 170 is opened on the outer side of the cabinet 100, and an installation cover 171 and a thermal protector 172 are installed on the installation opening 170. During installation, the heating element 700 is installed in the installation opening 170, and the thermal protector 172 and the installation cover 171 are installed. The thermal protector 172 mainly plays a protective role to prevent the heating element 700 from overheating. When maintaining the heating element 700, the installation cover 171 can be directly opened for easy maintenance.

[0036] In some embodiments, Figure 3 As shown, the cabinet 100 includes a cabinet door 110 , and the air inlet 200 , the air supply inlet 400 , and the air outlet 300 are arranged on a side of the cabinet 100 directly opposite to the cabinet door 110 , and the air inlet 200 and the air supply inlet 400 are located above the air outlet 300 . The cabinet door 110 on the cabinet 100 is generally arranged at the front side of the cabinet 100, and the air guide outlet 300 is arranged at the rear side of the cabinet 100. The new air added enters the cabinet 100 from the air guide outlet 300. The new air has a tendency to push the humid air inside the cabinet 100 forward. When the user opens the cabinet door 110, the humid air inside will be discharged from the cabinet opening. Generally, the disinfection cabinet is provided with an exhaust pipe 180 with a pressure relief exhaust function at the position of the cabinet door 110. After the new air is added, the pressure inside the cabinet 100 will increase. At this time, the exhaust pipe 180 is opened, and the humid air can also be discharged from the exhaust pipe 180, which can effectively improve the dehumidification effect and efficiency; at the same time, considering Due to the high density of humid air, the humid air will sink and gather at the lower part of the cabinet 100 under the action of gravity. The air inlet 200 and the air supply inlet 400 are arranged above the air outlet 300, that is, the air outlet 300 is arranged at the lower part of the cabinet 100, and the air inlet 200 and the air supply inlet 400 are arranged at the upper part of the cabinet 100, so that the internal circulating airflow flows from top to bottom in the air guide channel 130, and the internal circulating airflow flows from bottom to top in the cabinet 100, so that the circulating airflow drives the humid air inside the cabinet 100 to flow from bottom to top, so that the humid air and the new air outside are mixed more fully, so that the air inside the cabinet 100 can be quickly and evenly dehumidified.

[0037] The above-mentioned air guide channel 130 can be arranged on the inside or outside of the cabinet 100. When the air guide channel 130 is arranged on the inside of the cabinet 100, a vent corresponding to the air supplement inlet 400 is arranged on the wall of the cabinet, and the air supplement inlet 400 is connected with the outside of the cabinet 100 through the vent. When the air guide channel 130 is arranged on the outside of the cabinet 100, a vent corresponding to the air guide inlet 200 and the air guide outlet 300 is arranged on the wall of the cabinet to realize the communication between the air guide channel 130 and the inside of the cabinet.

[0038] In some embodiments, an air guide is provided in the cabinet 100, and the air guide is in the shape of a tube. The air guide channel 130 is provided in the air guide and is provided along the length direction of the air guide. The air guide in the shape of a tube, that is, the air guide can be a square tube, a round tube or other irregular special-shaped tubes, and can be regarded as a tube as long as it is a semi-enclosed member with three ports communicating with each other. The three ports are the air guide inlet 200, the air supplement inlet 400, and the air guide outlet 300. Such an air guide has the advantage of being easy to install, and because it is independent of the cabinet 100, the air guide inlet 200, the air supplement inlet 400, and the air guide outlet 300 can be freely designed, which is convenient for optimizing the air inlet and air outlet of the air guide. In addition, the air guide is further provided in the cabinet 100 or in the cabinet 100.

[0039] In other embodiments, the air guide body is in the shape of a cover plate, and an air guide passage 130 is formed between the air guide body and a side wall of the cabinet 100. The cover plate-shaped air guide body refers to an air guide body that is roughly in the shape of a thin-walled sheet metal, including a flat plate, a curved plate, a semi-enclosed shell, and the like, and also includes a form with or without holes. In short, the air guide body only serves as a part of the passage wall of the air guide passage 130, and the remaining passage wall is composed of the side wall of the cabinet 100. The above-mentioned technical improvement scheme of the cover plate-shaped air guide body is easy to process and saves the material constituting the air guide passage 130.

[0040] Of course, in other embodiments, a partial structure of the air guide body is in the shape of a tube, and the other partial structure of the air guide body is in the shape of a cover plate.

[0041] In some embodiments, the disinfection cabinet also includes a ventilation body 131 and a fixed air box 132 that are interconnected. The fixed air box 132 is in the shape of a tube, and the ventilation body 131 is in the shape of a cover plate. The fixed air box 132, the ventilation body 131 and the cabinet body together form an air guide channel 130, which makes the design of the air guide body more flexible and changeable, and also facilitates the cleaning and maintenance of the air guide channel in the air guide body.

[0042] There are many possible installation positions for the fan 600. The fan 600 can be installed in the fixed air vent 131 and the fixed air box 132, or at the air outlet 300. The main thing is to set the air inlet 200 and the air supply inlet 400 on the fixed air box 132 and on the negative pressure side of the fan 600. In this embodiment, the fan 600 is installed in a fixed air box 132, and the air guide outlet 300 is arranged on the ventilation body 131 and on the positive pressure side of the fan 600. The fixed air box 132 protects the fan 600 and also collects the incoming air of the air guide channel 130. Different fixed air boxes 132 are designed according to different cabinets 100. In other embodiments, the fixed air box 132 can adopt a split structure to facilitate cleaning of the interior of the fixed air box 132 and installation and disassembly of the fan 600. The ventilation body 131 guides the air outlet of the air guide channel 130. Different ventilation bodies 131 can be designed according to different internal circulations.

[0043] In some implementations, the electric control valve body further includes a substrate 540 and a rotating arm 550. A damper port 541 is provided on the substrate 540. The air supply inlet 400 is connected to the outside of the cabinet 100 through the damper port 541. One end of the rotating arm 550 is connected to the damper 530. The damper 530 covers the damper port 541. The rotating arm 550 is rotatably mounted on the substrate 540 through a rotating shaft 551. The electric control driving element 580 can drive the other end of the rotating arm 550 to swing around the rotating shaft 551, driving the damper 530 to open or close the damper port 541. The electric control driving element 580 can be of various types, such as a servo motor, a synchronous motor, or a solenoid valve, and can mainly drive the rotating arm 550 to rotate.

[0044] When the electric control drive element 580 drives the rotating arm 550 to rotate, the rotating arm 550 drives the damper 530 to move, mainly to generate a flow gap between the damper 530 and the damper port 541 to open the air supply inlet 400. As for the movement of the damper 530, in some embodiments, the damper 530 can be flipped up toward the inner port or the outer port of the damper port 541 relative to the damper port 541, so that the air supply inlet 400 is connected with the outside of the cabinet 100, and the axis of the rotating shaft 551 is perpendicular to the axis of the damper port 541; in other embodiments, the damper 530 can also move to the side of the damper port 541 relative to the damper port 541, and the axis of the rotating shaft 551 is parallel to the axis of the damper port 541.

[0045] The shape and size of the air valve opening 541 match those of the air door 530 , and may be circular, rectangular or other irregular shaped openings.

[0046] In some implementations, the electric control valve body further includes a reset elastic member 800, which can drive the damper 530 to reset to a state of closing the damper port 541. The reset elastic member 800 can keep the damper 530 in a state of closing the damper port 541, improve the stability of the damper 530 when closed, and prevent the damper 530 from shifting in a closed state, thereby causing air leakage at the damper port 541. The reset elastic member 800 can be a spring or an elastic sheet, and the installation position of the reset elastic member 800 needs to be determined according to the action of the damper 530.

[0047] In some embodiments, Figure 4 As shown, the electric control driving element 580 is a solenoid valve, the reset elastic member 800 is a spring, a connecting column is provided on the side wall of the substrate 540, and a connecting column is also provided on the side wall of the damper 530 facing away from the damper port 541, and the two ends of the spring are respectively connected to the two connecting columns, and the solenoid valve is fixed on the side wall of the substrate 540, as shown in FIG. Figure 5 As shown in FIG. 1 , when the air valve port 541 needs to be opened, the power shaft of the solenoid valve pushes the other end of the rotating arm 550 to swing, and one end of the rotating arm 550 drives the air door 530 to rotate, so that the air door 530 is misaligned with the air valve port 541, and the spring is stretched. At the same time, in order to make the rotation of the air door 530 stable, as shown in FIG. Figure 6 As shown, a circular arc-shaped slide groove 542 is provided on the side wall of the base plate 540, and the damper 530 can slide along the slide groove 542; Figure 6 As shown, when the air valve port 541 needs to be closed, the power shaft of the solenoid valve is reset, and under the elastic force of the spring, the air door 530 is pulled back to its original position and covers the air valve port 541. At the same time, in order to better achieve the positioning of the air door 530, as shown in FIG. Figure 5 As shown, a stopper 543 is provided at the edge of the air valve opening 541, and the air door 530 abuts against the stopper 543 to achieve positioning.

[0048] In some embodiments, the base plate 540 is one of the side walls of the cabinet 100. In this case, the damper 530 is directly mounted on the cabinet 100 to save space.

[0049] In other embodiments, Figure 4As shown, the air valve assembly 500 further includes a valve body box 570 installed on the side wall of the cabinet 100, the substrate 540 is one of the side walls of the valve body box 570, the components of the electric control valve body are installed in the valve body box 570, an air supply port 140 is provided on the side wall of the cabinet 100, the air supply inlet 400 is connected with the air valve port 541 through the air supply port 140, and a vent 571 connected with the outside of the cabinet 100 is also provided on the valve body box 570. At this time, the rotating arm 550, the air door 530, and the electric control driving element 580 on the air valve assembly 500 can be arranged in the valve body box 570 to form a whole, which is convenient for maintenance and installation, and also prevents other objects from interfering with the movement of the air door 530. The valve body box 570 can be directly fixed on the side wall of the cabinet 100. At the same time, the valve body box 570 can be split.

[0050] Furthermore, if Figure 1 As shown, a mounting groove 150 is recessed on the outer side of the cabinet 100, and the valve body box 570 is embedded in the mounting groove 150. During installation, the valve body box 570 is embedded in the mounting groove 150 to improve the firmness and stability of the installation of the air valve body box 570, and avoid misalignment, which causes the air supply port 140 to be staggered with the air valve port 541.

[0051] In some embodiments, Figure 4 As shown, a columnar fixing seat 560 is installed in the valve body box 570, and a first detection hole 572 and a second detection hole are respectively provided at positions where the side wall of the valve body box 570 and the two ends of the fixing seat 560 are relatively in conflict with each other. A detection port 160 connected to the inside of the cabinet 100 is provided on the side wall of the cabinet 100, and the second detection hole is opposite to the detection port 160. The first humidity sensor 510 and the second humidity sensor 520 are respectively installed on the two ends of the fixing seat 560. The first humidity sensor 510 detects the external air humidity of the cabinet 100 through the first detection hole 572, and the second humidity sensor 520 detects the internal air humidity of the cabinet 100 through the second detection hole and the detection port 160. The first humidity sensor 510 and the second humidity sensor 520 are installed on the fixing seat 560. On the one hand, the air valve assembly 500 can be modularized, including a power module composed of an electric control valve body and a damper 530, and a sensing detection module composed of a first humidity sensor 510, a second humidity sensor 520 and a fixing seat 560. During maintenance, different modules can be installed and disassembled. On the other hand, the setting of the fixing seat 560 can prevent the first humidity sensor 510 and the second humidity sensor 520 from touching other components when detecting the air humidity, which may cause a large error in the humidity value of the detected air.

[0052] Furthermore, a first mounting groove 561 and a second mounting groove are respectively provided on the two end surfaces of the fixing seat 560, the first humidity sensor 510 is embedded and installed in the first mounting groove 561, and the second humidity sensor 520 is embedded and installed in the second mounting groove, so that the first humidity sensor 510, the second humidity sensor 520 and the fixing seat 560 form an independent component, which can be installed and disassembled together on the valve body box 570. When disassembling for maintenance, the fixing seat 560 can be directly removed without removing the valve body box 570. An isolation layer 562 is hollowed out between the two ends of the fixing seat 560. The isolation layer 562 mainly plays a role of moisture isolation. The humidity at the two ends of the fixing seat 560 affects each other, and it also plays a role of facilitating wiring. The wiring isolation layer 562 of the first humidity sensor 510 and the second humidity sensor 520 passes through the electric control drive element 580 and is connected.

[0053] The above embodiments can be implemented crosswise if there is no contradiction, and are also applicable to various forms of disinfection cabinets, such as built-in disinfection cabinets. The invention is particularly effective in disinfecting paper items such as banknotes and books.

[0054] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
