Description

Technical Field

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

[0002] As a key equipment 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] Existing disinfection ventilation equipment generally uses ultraviolet disinfection lamps to sterilize the air or uses purification cotton to filter the air in actual applications. The patent with the publication number CN115892428B proposes a ship purification and disinfection type air conditioning ventilation device, which filters the air through purification consumables on the installation frame; the patent with the publication number CN113074426B proposes a ventilation and disinfection equipment for hospital infection departments, which disinfects the air in a transparent disinfection ball through an ultraviolet lamp;

[0004] After research by those skilled in the art, some drawbacks have been found:

[0005] On the one hand, after the purification consumables are used for a period of time, their purification ability will decrease significantly and need to be replaced regularly. Since ventilation equipment is usually installed at a relatively high position such as on a wall or a ceiling, the replacement process of the purification consumables will still be relatively cumbersome. Especially in areas where a large amount of bacteria are generated, the replacement frequency of the purification consumables is higher, which further increases the labor intensity of the staff and the accompanying safety risks are also greater;

[0006] On the other hand, the disinfection effect of the ultraviolet lamp is limited by its irradiation distance. In a large ventilation system, due to the limitations of air flow and equipment layout, the irradiation range of the ultraviolet lamp often cannot cover the entire ventilation system. Therefore, the disinfection effect is strong in the area close to the ultraviolet lamp, while the disinfection effect is weakened in the area farther away. This may lead to incomplete removal of bacteria in the air, resulting in the spread of bacteria in the ventilation system.

[0007] Therefore, we propose a ventilation equipment with good disinfection effect, convenient maintenance and automatic filter plate replacement. Summary of the Invention

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0042] Please refer to Figure 1-12 , the present invention provides a technical solution: a ventilation device with a disinfection function, including an outer shell 1 and a support plate 11 installed inside the outer shell 1. An ultraviolet lamp 12 is installed inside the outer shell 1, and the ultraviolet lamp 12 is located exactly in the middle of the top and bottom surfaces of the inner wall of the outer shell 1. It also includes:

[0043] A fan 13, the fan 13 is installed on the support plate 11 and is connected to the outer shell 1. The fan 13 is located at one end of the outer shell 1;

[0044] A storage box 2, the storage box 2 is installed at the bottom of the support plate 11, and activated carbon plates 21 are placed inside. There are several activated carbon plates 21;

[0045] Two pieces of quartz glass 3, the quartz glass 3 is installed inside the outer shell 1 to clamp the ultraviolet lamp 12, and the half close to the fan 13 is triangular. The quartz glass 3 refracts the ultraviolet rays emitted by the ultraviolet lamp 12, and a part of the ultraviolet rays near the fan 13 will be refracted to both sides of the ultraviolet lamp 12 in the part far from the fan 13;

[0046] Quartz glass 3 has extremely high transmittance to ultraviolet light and almost no absorption, and can penetrate ultraviolet light into the external environment to the greatest extent. At the same time, it can refract ultraviolet light. The refractive index of quartz glass 3 is generally between 1.45 and 1.47. As Figure 6 、 12 shown, the ultraviolet light near the fan 13 is refracted by the inclined plane of the quartz glass 3 and irradiates to the side away from the fan 13, and irradiates in a fan shape to the position in the housing 1 far from the ultraviolet lamp 12, thereby improving the air sterilization effect at the position far from the ultraviolet lamp 12.

[0047] Feeding mechanism 6, the feeding mechanism 6 is installed on the storage box 2 and is connected to the housing 1. The feeding mechanism 6 transports the activated carbon plate 21 in the storage box 2 to one end of the housing 1 away from the fan 13, and drives the activated carbon plate 21 to block one end of the housing 1 away from the fan 13;

[0048] Discharging mechanism 7, the discharging mechanism 7 is installed on the housing 1 and is connected to the support plate 11. The discharging mechanism 7 removes the used activated carbon plate 21 from the housing 1.

[0049] A first spring 22 is installed on the inner wall of the storage box 2 on the side 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 with a push plate 23. The push plate 23 is suspended in the storage box 2 through the first spring 22, and the push plate 23 is attached to the activated carbon plate 21.

[0050] When the activated carbon plate 21 farthest from the push plate 23 in the storage box 2 is taken away, the first spring 22 deforms, and drives the subsequent activated carbon plates 21 to be replenished in time through the push plate 23.

[0051] A replenishing mechanism 4 is installed on the storage box 2. The replenishing mechanism 4 includes a feeding shovel 41 installed through the storage box 2. The outer wall of the feeding shovel 41 is attached to the inner wall of the storage box 2. A cross-shaped chute 42 is opened on the feeding shovel 41. A cross-shaped slider 43 is arranged in the cross-shaped chute 42. A second spring 44 is installed on the cross-shaped slider 43. One end of the second spring 44 is fixed to the cross-shaped slider 43, and the other end is fixed to one end of the cross-shaped chute 42. The top of the cross-shaped slider 43 is attached to the activated carbon plate 21;

[0052] The replenishing mechanism 4 further includes a limiting mechanism 400 installed on the feeding shovel 41.

[0053] When the feeding shovel 41 and the storage box 2 are docked, it is a rectangular box with a double-layer bottom. 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 attached to the inner wall of one side of the feeding shovel 41.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] The feeding mechanism 6 includes a support member 60 and a supply member 61. The support member 60 includes circular grooves 601 oppositely formed on the inner wall of the outer shell 1. There are two pairs of circular grooves 601, which are arranged vertically. The centers of the circular grooves 601 are each installed with a first rotating shaft 602. The first rotating shaft 602 penetrates through the outer shell 1. A support rod 603 is installed on the first rotating shaft 602. Both ends of the support rod 603 are arcs that fit the circular grooves 601. A limiting groove 604 is formed on the support rod 603. The support rods 603 located between the same horizontal planes are fixed to each other by a connecting rod 605. A damping piece 606 is arranged in the limiting groove 604 on the support rod 603 above the inner part of the outer shell 1.

[0059] Since both ends of the support rod 603 are arcs that fit the circular grooves 601, after the activated carbon plate 21 is blocked, the sealing performance is better, so that the air flow needs to pass through the filtration of the activated carbon plate 21. The support rod 603 clamps the activated carbon plate 21 through the limiting groove 604. The damping piece 606 can delay the falling time of the activated carbon plate 21, ensuring that before the activated carbon plate 21 above completely falls, the activated carbon plate 21 below is replenished in time, and both activated carbon plates 21 are replenished to block one end of the outer shell 1 away from the blower 13.

[0060] The supply member 61 includes a first through hole 611 formed at the bottom of the storage box 2, a second through hole 612 formed on the support plate 11. A support frame 613 is fixed to the bottom of the storage box 2. A slide rail 614 is formed 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 slidably connected to the slide rail 614 respectively. The top end 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. First gears 617 are fixed to both ends of the output shaft of the double-output shaft motor 616. Second gears 618 are installed on both sides of the support frame 613 through shafts. A first chain 619 is connected between the first gear 617 and the second gear 618. The two first chains 619 are respectively fixed to both ends of the T-shaped plate 615.

[0061] When it is necessary to block one end of the housing 1 away from the fan 13 with the activated carbon plate 21, the double-output shaft motor 616 is turned on. 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 vertically rise 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 in the storage box 2 that overlaps with the first through hole 611. With the continuous rising 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 attached to the damping piece 606. Subsequently, the double-output shaft motor 616 rotates in the reverse direction. Similarly, the T-shaped plate 615 is driven to reset. During the reset process of the T-shaped plate 615, 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 its own gravity. However, the damping piece 606 increases the friction force it receives during the sliding process, so that the descending speed of the activated carbon plate 21 is slowed down, which is convenient for the next activated carbon plate 21 to be pushed 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 in the housing 1 are distributed up and down to block one end of the housing 1 away from the fan 13, so that when the air flow passes through the inside of the housing 1, it needs to pass through the filtration of the activated carbon plate 21.

[0062] The discharging mechanism 7 includes a sixth gear 71 sleeved on one of the first rotating shafts 602. The sixth gear 71 is located in the upper part inside the housing 1. A servo motor 74 is installed on the first rotating shaft 602 below the same side of 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 discharging mechanism 7 further includes an adaptor 700 installed on the housing 1.

[0063] The adaptor 700 includes an elastic piece 701 installed at one end of the inner wall top of the housing 1 near the second through hole 612. An adaptor plate 702 is installed on the elastic piece 701. The first through hole 611, the second through hole 612, the elastic piece 701, and the adaptor plate 702 are located on the same horizontal plane.

[0064] When the activated carbon plate 21 at one 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. The interval time period can be set according to the actual use scenario. This is prior art and will not be elaborated here. The servo motor 74 drives the first rotating shaft 602 connected to it to rotate. 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 and the first rotating shaft 602 directly above it rotate in the same direction. The support rods 603 connected to both rotate in the same direction. During the rotation process, under the action of its own gravity, it slides out of the limiting groove 604 of its corresponding support rod 603. Subsequently, the servo motor 74 starts in the reverse direction and stops after the support rod 603 returns to its original position, facilitating the feeding mechanism 6 to provide a new activated carbon plate 21 for replenishment.

[0065] Since the activated carbon plate 21 has a certain thickness and the elastic piece 701 itself has a certain elasticity, it ensures that the activated carbon plate 21 can be turned smoothly during the turning process, avoiding large resistance caused by rigid contact during the turning of the activated carbon plate 21, thereby causing equipment failures.

[0066] A laser sensor 8 is installed inside the storage box 2 near one side of the first through hole 611. When the last group of activated carbon plates 21 are used up, the laser sensor 8 detects that the feeding shovel 41 and the inside of the storage box 2 are empty. Subsequently, it can send a signal to the system to which the device belongs to remind relevant staff to replenish in a timely manner, making it more intelligent.

[0067] The working principle is as follows: The staff replenishes the activated carbon plate 21 into the feeding shovel 41. As the activated carbon plate 21 is replenished, the second spring 44 is stretched, and at the same time drives the cross slider 43 to clamp and fix the activated carbon plate 21. Subsequently, the feeding shovel 41 is inserted into the inside of the storage box 2. During the insertion process, the inclined surfaces of the L-shaped rods 401 on both sides of the feeding shovel 41 come into contact with the corresponding limiting rods 404 and squeeze the limiting rods 404. The limiting rods 404 compress the third spring 405 inside the square cylinder 403. When the third through hole 402 on the L-shaped rod 401 completely coincides with the limiting rod 404, the third spring 405 returns to its original position, driving the limiting rod 404 to return to its original position and penetrate through the third through hole 402, completing the connection between the feeding shovel 41 and the storage box 2;

[0068] Turn on the double-output shaft motor 616. 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 restriction 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 vertically rise 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 that overlaps with the first through hole 611 in the storage box 2. With the continuous rising 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 surface of the activated carbon plate 21 fits with the damping piece 606. Subsequently, the double-output shaft motor 616 rotates in the reverse direction. Similarly, the T-shaped plate 615 is driven to 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 sequentially pushes the other activated carbon plates 21, and the position of the first through hole 611 is replenished by a new activated carbon plate 21. During 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 its own gravity. However, the damping piece 606 increases the friction force it receives during the sliding process, slowing down the descending speed of the activated carbon plate 21. At this time, the double-output shaft motor 616 is started again, and the next activated carbon plate 21 is pushed 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 in the housing 1 are distributed up and down, blocking one end of the housing 1, so that when the air flow passes through the inside of the housing 1, it all needs to pass through the filtration of the activated carbon plate 21;

[0069] When the activated carbon plate 21 at one end of the housing 1 far from the blower 13 has been used for a period of time, the servo motor 74 is turned on. The interval time period can be set according to the actual use scenario. This is prior art, so it will not be elaborated here. The servo motor 74 drives the first rotating shaft 602 connected to it to rotate. 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 rods 603 connected to both rotate in the same direction. During the rotation process, under the action of its own gravity, it slides out of the limiting groove 604 of its corresponding support rod 603. Subsequently, the servo motor 74 starts in the reverse direction and stops after the support rod 603 is reset, facilitating the feeding mechanism 6 to provide a new activated carbon plate 21 for replenishment;

[0070] It should be noted that the staff can set a collection box below the sliding position of the activated carbon plate 21 to facilitate the centralized treatment of the used activated carbon plate 21;

[0071] In this device, two activated carbon plates 21 are used each time to block half of the ventilation opening. Using a single activated carbon plate 21 with the same size as one side of the outer shell 1 can also achieve the same disinfection and filtration effect. However, if a single plate is used, it means that the height of the storage box 2 needs to be equal to the height of the outer shell 1. For a factory building with a fixed ventilation opening size, the ventilation efficiency will be greatly reduced;

[0072] This device can be replenished with activated carbon plates 21 into the feeding shovel 41 once, and can be used for a long time. The replenishment process is simple. Under the refraction of the quartz glass 3 with a sloped part, the ultraviolet lamp 12, in cooperation with the activated carbon plate 21, can 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.
