Description

Technical Field

[0001] The invention relates to the technical field of ventilation equipment, in particular to ventilation equipment with a disinfection function. Background Art

[0002] As a key device for improving indoor air quality, ventilation equipment has been widely used in many fields, such as hospital infection departments, public toilets and other places with high concentrations of bacteria and odors. The air in these places often contains a large number of bacteria, viruses and harmful gases, posing a serious threat to people's health.

[0003] In practical applications, existing disinfection and ventilation equipment generally uses ultraviolet disinfection lamps to sterilize the air or uses purification cotton to filter the air. Patent No. CN115892428B proposes a ship purification and disinfection air conditioning ventilation device, which filters the air through purification consumables installed on the frame; Patent No. CN113074426B proposes a ventilation and disinfection equipment for hospital infection departments, which uses ultraviolet lamps to disinfect the air in a transparent disinfection ball; After research by technicians in this field, some disadvantages were found: On the one hand, after a period of use, the purification capacity of purification consumables will be significantly reduced and they need to be replaced regularly. Since ventilation equipment is usually installed at high positions such as walls or wall tops, the replacement process of purification consumables is still cumbersome, especially in areas where more bacteria are produced. The replacement frequency of purification consumables is higher, which further increases the labor intensity of staff and is accompanied by greater safety risks. On the other hand, the disinfection effect of ultraviolet lamps is limited by their irradiation distance. In large ventilation systems, due to the limitations of air flow and equipment layout, the irradiation range of ultraviolet lamps often cannot cover the entire ventilation system. Therefore, the disinfection effect is strong in areas closer to the ultraviolet lamps, while the disinfection effect is weakened in areas farther away. This may result in incomplete removal of bacteria in the air, resulting in the spread and diffusion of bacteria in the ventilation system.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-12 The present invention provides a technical solution: a ventilation device with a disinfection function, comprising a housing 1 and a support plate 11 installed in the housing 1, an ultraviolet lamp 12 is installed inside the housing 1, and the ultraviolet lamp 12 is located in the middle of the top surface and the bottom surface of the inner wall of the housing 1, and also includes: The fan 13 is mounted on the support plate 11 and connected to the housing 1. The fan 13 is located at one end of the housing 1; A storage box 2 is installed at the bottom of the support plate 11, and an activated carbon plate 21 is placed inside. The activated carbon plate 21 has a plurality of; Quartz glass 3, there are two pieces of quartz glass 3, which are installed inside the housing 1 to clamp the ultraviolet lamp 12, and the half close to the fan 13 is triangular. The quartz glass 3 refracts the ultraviolet light emitted by the ultraviolet lamp 12, and part of the ultraviolet light close to the fan 13 will be refracted to the two sides of the ultraviolet lamp 12 far away from the fan 13; The quartz glass 3 has a very high transmittance to ultraviolet light and almost no absorption, and can penetrate the ultraviolet light into the external environment to the greatest extent, and can refract the ultraviolet light at the same time. The refractive index of the quartz glass 3 is generally between 1.45 and 1.47. Figure 6 , 12 As shown, the ultraviolet light near the fan 13 is refracted by the inclined surface of the quartz glass 3 and irradiated toward the side away from the fan 13, and irradiated toward the position farther from the ultraviolet lamp 12 in the housing 1 in a fan shape, thereby improving the air sterilization effect at a position farther from the ultraviolet lamp 12.

[0020] A feeding mechanism 6, which is installed on the storage box 2 and connected to the housing 1. The feeding mechanism 6 transports the activated carbon plate 21 in the storage box 2 to the end of the housing 1 away from the fan 13, and drives the activated carbon plate 21 to block the end of the housing 1 away from the fan 13; The unloading mechanism 7 is installed on the housing 1 and connected to the support plate 11 . The unloading mechanism 7 removes the used activated carbon plate 21 from the housing 1 .

[0021] A first spring 22 is installed on the inner wall of the storage box 2 close to the fan 13. One end of the first spring 22 is fixed to the storage box 2, and the other end is fixed to a push plate 23. The push plate 23 is suspended inside the storage box 2 by the first spring 22, and the push plate 23 is in contact with the activated carbon plate 21.

[0022] When the activated carbon plate 21 farthest from the push plate 23 in the storage box 2 is taken away, the first spring 22 is deformed, and the subsequent activated carbon plates 21 are driven to be replenished in time through the push plate 23 .

[0023] A replenishing mechanism 4 is installed on the storage box 2, and the replenishing mechanism 4 includes a loading shovel 41 installed through the storage box 2, the outer wall of the loading shovel 41 is in contact with the inner wall of the storage box 2, a cross slide 42 is provided on the loading shovel 41, a cross slider 43 is provided in the cross slide 42, a second spring 44 is installed on the cross slider 43, one end of the second spring 44 is fixed to the cross slider 43, and the other end is fixed to one end of the cross slide 42, and the top of the cross slider 43 is in contact with the activated carbon plate 21; The replenishing mechanism 4 further includes a limiting mechanism 400 installed on the loading shovel 41 .

[0024] When the loading shovel 41 and the storage box 2 are docked, they form a rectangular box with a double bottom layer. Under the thrust of the first spring 22 and the push plate 23 , the activated carbon plate 21 farthest from the fan 13 is always in contact with the inner wall of one side of the loading shovel 41 .

[0025] The limiting mechanism 400 includes an L-rod 401 relatively installed on the side wall of the loading shovel 41, the top of the L-rod 401 is an inclined surface, and a third through hole 402 is opened on the L-rod 401. Square tubes 403 are fixed on both sides of the storage box 2. A limiting rod 404 is installed through the square tube 403, and the top of the limiting rod 404 is an inclined surface. A third spring 405 is installed in the square tube 403, and one end of the third spring 405 is fixed to the storage box 2, and the other end is fixed to the limiting rod 404.

[0026] When the activated carbon plate 21 in the storage box 2 needs to be replenished, the staff uses their fingers or other rod-shaped tools to press the limit rod 404 at the same time. Under the action of the first spring 22 and the push plate 23, the loading shovel 41 moves outward, releasing the limit between the loading shovel 41 and the storage box 2 by the L rod 401 and the limit rod 404. Then the staff pulls the loading shovel 41 out of the storage box 2, pulls open the cross slider 43, and then puts the activated carbon plate 21 into the upper loading shovel 41. Then, the cross slider 43 is released. The cross slider 43 is pressed against the activated carbon plate 21 under the action of the second spring 44. After the replenishment is completed, the staff only needs to insert the loading shovel 41 back into the storage box 2. During the insertion process, the inclined surfaces of the L rod 401 on both sides of the loading shovel 41 contact with the limiting rod 404 at the corresponding position and squeeze the limiting rod 404. The limiting rod 404 compresses the third spring 405 in the square tube 403. When the third through hole 402 on the L rod 401 completely overlaps with the limiting rod 404, the third spring 405 resets, driving the limiting rod 404 to reset, and penetrates the third through hole 402 to complete the docking between the loading shovel 41 and the storage box 2.

[0027] A flow balancing plate 5 is installed in the shell 1. There are two groups of flow balancing plates 5, one group is located between the upper quartz glass 3 and the upper inner wall of the shell 1, and the other group is located between the lower quartz glass 3 and the support plate 11, and each group of flow balancing plates 5 is located on both sides of the inner wall of the shell 1.

[0028] When the airflow passes through the previous flow equalizing plate 5, the airflow enters the larger space between the two flow equalizing plates 5 from the smaller space in the through hole of the flow equalizing plate 5, and the flow velocity slows down. The latter flow equalizing plate 5 partially blocks the airflow between the two flow equalizing plates 5 again, so that the airflow passing through the latter flow equalizing plate 5 is limited. The airflow can stay between the two flow equalizing plates 5 for a longer time, further improving the sterilization effect. At the same time, the airflow distribution through the flow equalizing plate 5 is more uniform, and the activated carbon plate 21 can be efficiently utilized when filtering the airflow.

[0029] The feeding mechanism 6 includes a support member 60 and a supply member 61. The support member 60 includes circular grooves 601 that are relatively opened on the inner wall of the outer shell 1. There are two pairs of circular grooves 601, which are respectively arranged up and down. The center of the circular grooves 601 is installed with a first rotating shaft 602. The first rotating shaft 602 penetrates the outer shell 1. A support rod 603 is installed on the first rotating shaft 602. Both ends of the support rod 603 are arc-shaped and fit the circular groove 601. A limiting groove 604 is opened on the support rod 603. The support rods 603 located in the same horizontal plane are fixed by connecting rods 605. A damping plate 606 is set on the limiting groove 604 on the support rod 603 located on the upper part of the inner part of the outer shell 1.

[0030] Since both ends of the support rod 603 are arc-shaped and fit the circular groove 601, after the activated carbon plate 21 is sealed, the sealing is better, so that the airflow must be filtered by the activated carbon plate 21. The support rod 603 clamps the activated carbon plate 21 through the limiting groove 604, and the damping plate 606 can delay the falling time of the activated carbon plate 21 to ensure that the activated carbon plate 21 below is replenished in time before the activated carbon plate 21 located above falls completely. Both activated carbon plates 21 are replenished, and the end of the casing 1 away from the fan 13 is blocked.

[0031] The supply member 61 includes a first through hole 611 opened at the bottom of the storage box 2, a second through hole 612 is opened on the support plate 11, a support frame 613 is fixed to the bottom of the storage box 2, a slide rail 614 is opened on the support frame 613, a T-shaped plate 615 is installed through the slide rail 614, both ends of the T-shaped plate 615 are respectively slidably connected to the slide rail 614, and the top of the T-shaped plate 615 can pass through the first through hole 611. It also includes a double-output shaft motor 616 installed at the bottom end of the support frame 613, and both ends of the output shaft of the double-output shaft motor 616 are fixed with first gears 617, and second gears 618 are installed on both sides of the support frame 613 through the shaft. A first chain 619 is connected between the first gear 617 and the second gear 618, and the two first chains 619 are respectively fixedly connected to the two ends of the T-shaped plate 615.

[0032] When it is necessary to seal the end of the casing 1 away from the fan 13 through the activated carbon plate 21, the double-output shaft motor 616 is turned on, and the output shaft of the double-output shaft motor 616 drives the first gear 617 to rotate, and the first gear 617 cooperates with the second gear 618 to drive the first chain 619 for transmission. Due to the limitation of the slide rail 614 on the support frame 613, the T-shaped plate 615 can only move in the vertical direction. With the transmission of the first chain 619, the T-shaped plate 615 is synchronously driven to rise vertically in the slide rail 614. During the rising process of the T-shaped plate 615, it passes through the first through hole 611 and contacts the bottom of the activated carbon plate 21 overlapping with the first through hole 611 in the storage box 2. As the T-shaped plate 615 continues to rise, the T-shaped plate 615 drives the activated carbon plate 21 in contact with it to rise, and finally the activated carbon plate 21 is supported by the support frame 613. The limit groove 604 of the support rod 603 is clamped, and at this time, the side of the activated carbon plate 21 is in contact with the damping plate 606, and then the double-output shaft motor 616 rotates in the opposite direction. Similarly, the T-shaped plate 615 is driven to reset. During the resetting of the T-shaped plate 615, the activated carbon plate 21 in the limit groove 604 of the support rod 603 loses the support of the T-shaped plate 615 and begins to slide down under the action of its own gravity. However, the damping plate 606 increases the friction force it encounters when it slides down, so that the descending speed of the activated carbon plate 21 is slowed down, making it convenient for the next activated carbon plate 21 to be pushed into the limit groove 604 of the support rod 603 located below in the same way. In this state, the two activated carbon plates 21 located in the outer shell 1 are distributed up and down, and the end of the outer shell 1 away from the fan 13 is blocked, so that the airflow must be filtered by the activated carbon plate 21 when passing through the inside of the outer shell 1.

[0033] The unloading mechanism 7 includes a sixth gear 71 sleeved on one of the first rotating shafts 602, and the sixth gear 71 is located in the upper part of the inner part of the outer shell 1. A servo motor 74 is installed on the first rotating shaft 602 located on the same side and below the sixth gear 71. One side of the servo motor 74 is fixed to the wall of the installation equipment. The output shaft of the servo motor 74 is fixed to the first rotating shaft 602 and is sleeved with a fourth gear 75. The sixth gear 71 and the fourth gear 75 are connected by a second chain 77. The unloading mechanism 7 also includes an adapter 700 installed on the outer shell 1.

[0034] The adaptor 700 includes an elastic sheet 701 mounted on the top of the inner wall of the housing 1 near one end of the second through hole 612, and an adaptor plate 702 is mounted on the elastic sheet 701. The first through hole 611, the second through hole 612, the elastic sheet 701 and the adaptor plate 702 are located in the same horizontal plane.

[0035] When the activated carbon plate 21 located at the end of the casing 1 away from the fan 13 has been used for a period of time, the servo motor 74 is turned on, and the interval time period can be set according to the actual usage scenario. This is the prior art, so it will not be repeated. The servo motor 74 drives the first rotating shaft 602 connected to it to rotate, and at the same time its output shaft drives the sixth gear 71 to rotate through the fourth gear 75 and the second chain 77, and the first rotating shaft 602 connected to the sixth gear 71 rotates synchronously, that is, the first rotating shaft 602 connected to the output shaft of the servo motor 74 rotates in the same direction as the first rotating shaft 602 directly above it, and the support rod 603 connected to the two rotates in the same direction. During the rotation, under the action of its own gravity, it slides out of the limiting groove 604 of the corresponding support rod 603, and then the servo motor 74 starts in reverse and stops after the support rod 603 is reset, so that the feeding mechanism 6 can provide new activated carbon plates 21 for replenishment.

[0036] Since the activated carbon plate 21 has a certain thickness, the elastic sheet 701 itself has a certain elasticity, which ensures that the activated carbon plate 21 can be turned over smoothly, avoiding large resistance due to rigid contact during the turning of the activated carbon plate 21, thereby causing equipment failure.

[0037] A laser sensor 8 is installed on one side of the storage box 2 near the first through hole 611. When the last set of activated carbon plates 21 is used, the laser sensor 8 detects that the loading shovel 41 and the storage box 2 are empty, and then sends a signal to the system to which the equipment belongs, reminding relevant staff to replenish them in time, which is more intelligent.

[0038] The working principle is as follows: the staff replenishes the activated carbon plate 21 into the upper material shovel 41. As the activated carbon plate 21 is replenished, the second spring 44 is stretched, and at the same time, the cross slider 43 is driven to clamp and fix the activated carbon plate 21. Then, the loading shovel 41 is inserted into the storage box 2. During the insertion process, the inclined surfaces of the L rods 401 on both sides of the loading shovel 41 contact with the limiting rods 404 at the corresponding positions, and squeeze the limiting rods 404. The limiting rods 404 compress the third spring 405 in the square tube 403. When the third through hole 402 on the L rod 401 completely overlaps with the limiting rod 404, the third spring 405 is reset, driving the limiting rod 404 to reset, and passing through the third through hole 402, completing the connection between the loading shovel 41 and the storage box 2. The double-output shaft motor 616 is turned on, and the output shaft of the double-output shaft motor 616 drives the first gear 617 to rotate. The first gear 617 cooperates with the second gear 618 to drive the first chain 619 for transmission. Due to the limitation of the slide rail 614 on the support frame 613, the T-shaped plate 615 can only move in the vertical direction. With the transmission of the first chain 619, the T-shaped plate 615 is synchronously driven to rise vertically in the slide rail 614. During the rising process of the T-shaped plate 615, it passes through the first through hole 611 and contacts the bottom of the activated carbon plate 21 overlapping with the first through hole 611 in the storage box 2. With the continuous rise of the T-shaped plate 615, the T-shaped plate 615 drives the activated carbon plate 21 in contact with it to rise. Finally, the activated carbon plate 21 is clamped by the limiting groove 604 of the support rod 603 located above. At this time, the side of the activated carbon plate 21 is in contact with the damping plate 606. Then the double-output shaft motor 616 rotates in the opposite direction. Similarly, it drives the T The T-shaped plate 615 is reset. Since the activated carbon plate 21 originally located at the position of the first through hole 611 is pushed away, under the action of the first spring 22 and the push plate 23, the push plate 23 pushes the other activated carbon plates 21 in sequence, and the first through hole 611 is replenished by a new activated carbon plate 21. In this process, the activated carbon plate 21 in the limiting groove 604 of the support rod 603 loses the support of the T-shaped plate 615 and begins to slide down under the action of its own gravity. However, the damping plate 606 increases the friction force it receives when it slides down, so that the speed of the activated carbon plate 21 descending is slowed down. At this time, the double-output shaft motor 616 is started again to push the next activated carbon plate 21 into the limiting groove 604 of the support rod 603 located below in the same way. In this state, the two activated carbon plates 21 located in the shell 1 are distributed up and down, blocking one end of the shell 1, so that when the airflow passes through the inside of the shell 1, it must be filtered by the activated carbon plate 21. When the activated carbon plate 21 located at the end of the housing 1 away from the fan 13 has been used for a period of time, the servo motor 74 is turned on, and the interval time period can be set according to the actual use scenario. This is the prior art, so it will not be repeated. The servo motor 74 drives the first rotating shaft 602 connected to it to rotate, and at the same time, its output shaft drives the sixth gear 71 to rotate through the fourth gear 75 and the second chain 77. The first rotating shaft 602 connected to the sixth gear 71 rotates synchronously, that is, the first rotating shaft 602 connected to the output shaft of the servo motor 74 rotates in the same direction as the first rotating shaft 602 directly above it, and the support rod 603 connected to the two rotates in the same direction. During the rotation, under the action of its own gravity, it slides out of the limiting groove 604 of the corresponding support rod 603, and then the servo motor 74 starts in the reverse direction and stops after the support rod 603 is reset, so that the feeding mechanism 6 can provide new activated carbon plates 21 for replenishment; It should be noted that the staff can set a collection box below the activated carbon plate 21 to facilitate the centralized treatment of the used activated carbon plate 21; The device uses two activated carbon plates 21 to block half of the vents at a time. Using a single activated carbon plate 21 of the same size as one side of the shell 1 can also achieve the same disinfection and filtration effect. However, if a single activated carbon plate 21 is used, it means that the height of the storage box 2 needs to be equal to the height of the shell 1. For a factory building with a fixed vent size, the ventilation efficiency is greatly reduced. The device replenishes the activated carbon plate 21 into the upper material shovel 41 once, and can be used for a long time, and the replenishment process is simple to operate. The ultraviolet lamp 12, under the refraction of the quartz glass 3, which is partially inclined, cooperates with the activated carbon plate 21 to eliminate bacteria and viruses in the air and remove odors at the same time, and has a high degree of automation and low labor intensity.
