Description

Liftable ultraviolet sterilizer

Technical Field

Background

In the environment where people and bacteria and viruses coexist, some bacteria or viruses causing human diseases are often activated on daily utensils such as infant toys, student stationery, computer keyboards, microphones, telephones and the like. Therefore, killing these bacteria or viruses which are harmful to human health by disinfection is an important task for preventing infection and maintaining physical health. One of the commonly used sterilization methods is the ultraviolet sterilization method. When the disinfection is carried out in public places, families or small areas, the disinfection can be carried out by using an ultraviolet sterilization method, so that various types of ultraviolet sterilizers can be manufactured.

The ultraviolet sterilizer can be used in the process of cargo transportation, but sometimes the light source is blocked due to the influence of the installation position, so that the illumination intensity is not enough, and various solutions are provided for the problem in the prior art, for example, in the patent document with the application number of CN201510108530.2, the ultraviolet sterilizer capable of lifting is disclosed, and an ultraviolet lifting seat of the ultraviolet sterilizer can drive an ultraviolet lamp to lift so as to comprehensively sterilize and disinfect the environment near the sterilizer.

Although the operation solves the problem that the ultraviolet sterilizer is easy to block illumination due to the fact that the position of the ultraviolet sterilizer is fixed, the limitation exists when the ultraviolet sterilizer faces illumination dead angles (for example, a blocking object exists between goods and the sterilizer or an area which is difficult to reach by light rays), for example, the goods installation box of the goods is packed through a paper box when the goods are transported, once the surface of a carton box is sunken, when the ultraviolet sterilizer rises, the light irradiation angle of the sterilizer is unchanged, so that the sunken part on the surface of the carton box cannot be irradiated, and the irradiation dead angles exist, so that the sterilization efficiency is influenced.

In the process that the lamp tube 2 extends out of the fixed lamp holder 1, the driving part 7 can drive the light bar deflection part 5 to move in the installation cavity, and taking fig. 1 as an example, when the lamp tube 2 extends out of the fixed lamp holder 1, the driving part 7 can be meshed with the light bar deflection part 5 to move anticlockwise.

The lifting mechanism 3 can realize the rapid lifting of the lamp tube 2 without occupying a large space, when the lifting mechanism is implemented, gas is directly injected into the inflatable bag seat 31 through an external inflation and exhaust part (the part is mainly matched with the action that the lamp tube 2 extends out of the fixed lamp holder 1, namely, the inflatable bag seat 31 is inflated and expanded to push out the lamp tube 2, and the gas in the inflatable bag seat 31 is exhausted to enable the lamp tube 2 to go deep into the fixed lamp holder 1), the specific structure of the inflatable bag seat 31 is shown in figure 1 and consists of a stabilizing block and an air bag, when the inflatable bag seat 31 pushes the lamp tube 2 out of the fixed lamp holder 1, the inserting and embedding column 32 can slide along the sliding groove 11, so that the extending of the lamp tube 2 cannot shake, and the elastic clamping table 12 can play a role of limiting speed in the process that the lamp tube 2 extends out of or goes deep into the fixed lamp holder 1, so that the extending or deep speed of the lamp tube 2 cannot be too fast, and the elastic clamping table 12 can also stabilize the insertion embedding column 32, so that the lamp tube 2 which stops moving cannot easily shake.

As shown in fig. 1 and 5, the light bar deflection component 5 includes a plurality of driving tooth posts 51 and a driving belt 52, the plurality of driving tooth posts 51 are sequentially connected with the plurality of rotating shafts 8 in a one-to-one correspondence manner, the driving belt 52 is disposed in the installation cavity, the driving belt 52 is sleeved on the outer sides of the plurality of rotating shafts 8, one end of the driving belt 52 close to the fixed lamp holder 1 penetrates through the installation cavity and extends to the outer side to be connected with the driving component 7, and the driving belt 52 can be driven by the driving component 7 to slide so as to guide the plurality of driving tooth posts 51 to sequentially rotate;

the limiting component 6 comprises a sliding clamping column 61 with an end connected to the inner wall of the installation cavity (the connection mode at the position can be rotation or sliding, the position is preferably sliding and can be separated from a clamping groove 63 more easily), a pushing part 62 connected with the side wall of the sliding clamping column 61 is installed on the inner wall of the installation cavity, a clamping groove 63 is formed in the position, corresponding to the sliding clamping column 61, of the side wall of the rotating shaft 8, the clamping groove 63 can clamp the sliding clamping column 61 to limit the rotation of the rotating shaft 8, and the sliding clamping column 61 can be pushed by the guide belt 52 to be separated from the clamping groove 63 to release the limitation on the rotating shaft 8.

The lamp strip deflection part 5 can be matched with the limiting part 6 to realize regulation and limitation of irradiation light, when the lamp strip deflection part is implemented specifically, once the inflatable bag seat 31 pushes the lamp tube 2 to extend out of the fixed lamp holder 1, the guide belt 52 can be directly driven by the driving part 7 at the moment, so that the lamp strip can move in the installation cavity, the lamp strip moves anticlockwise in the process of the anticlockwise movement in the figure 1, the guide belt 52 can push the sliding clamping column 61, the sliding clamping column 61 can slide along the inner wall of the installation cavity until the sliding clamping column is separated from the clamping groove 63, the specific structure of the sliding clamping column 61 is shown in the figure 3, the T shape is preferred, the purposes of clamping the clamping groove 63 and compressing the pushing part 62 can be simultaneously realized, and the pushing part 62 can be preferably composed of a transverse plate connected to the inner wall of the installation cavity and a spring (also can be an elastic sheet) arranged on the transverse plate.

After the guiding belt 52 is pushed away from the sliding clamping column 61, the driving toothed columns 51 sequentially drive the driving toothed columns 51 sleeved on the outer sides of the rotating shafts 8, so that the rotating shafts 8 sequentially rotate.

In summary, the guide belt 52 moving counterclockwise pushes the sliding locking pin 61 out of the locking groove 63, and then drives the plurality of rotation shafts 8 to rotate in sequence.

In a daily situation, the sliding locking post 61 is inserted into the locking groove 63, so that the lamp post (specifically, a small ultraviolet germicidal lamp, such as an ultraviolet LED germicidal lamp) is not easily displaced.

As shown in fig. 1, 4 and 5, the specific structure of the guide belt 52 is not unique, but the guide belt 52 in the prior art (corresponding to a small conveyor belt in the prior art) is difficult to achieve the purpose of sequentially driving the plurality of rotating shafts 8 to rotate in practice, so that preferably, the guide belt 52 includes a sliding belt 521 sleeved outside the plurality of rotating shafts 8, both ends of the sliding belt 521 are provided with supporting tooth columns 522, the supporting tooth column 522 at one end of the sliding belt 521 is connected with the inner wall of the installation cavity, the supporting tooth column 522 at the other end of the sliding belt 521 is connected with the inflatable bag holder 31, the inner side wall of one end of the fixed lamp holder 1 far away from the sliding belt 521 is provided with a driving tooth group 523 engaged with the driving tooth column 51, and the sliding belt 521 can drive the driving tooth group 523 to move from the top end of the lamp cylinder 2 to one side of the fixed lamp holder 1 so as to sequentially rotate the plurality of driving tooth columns 51;

the outer surface of the sliding belt 521 is provided with a plurality of catching grooves 524.

In this embodiment, the specific structure of the driving gear set 523 is as shown in fig. 5, and the driving gear set 523 is composed of a plurality of gear sets, and the number of the gear sets should be set according to the angle to be adjusted, for example, because the number of the racks on the driving gear 51 in fig. 5 is 8, the driving gear 51 rotates 45 degrees by being rotated every time when being toggled, if the user sets two gear sets, the rotating angles of the plurality of rotating shafts 8 are all 45 degrees, and if the driving gear set is to be set to other angles, the number of the racks on the driving gear 51 and the number of the gear sets need to be adjusted.

The leading belt 52 needs to work together with the leading part 7 when working.

In this embodiment, the driving gear set 523 can drive the gear column 51 to move only by contacting the driving gear column 51, that is, after the sliding belt 521 drives the driving gear set 523 to pass through the first driving gear column 51, the driving gear column 51 can not move continuously due to being unable to contact the driving gear set 523 any more, and thus can only be stationary, after the driving gear set 523 passes through the second driving gear column 51, the moving state of the second driving gear column 51 is the same as the moving state of the first driving gear column 51, and in order to further prevent the rotation phenomenon of the rotating shaft 8, a friction resistance plate connected with the side wall of the rotating shaft 8 can be arranged on the inner wall of the installation cavity, that is, the rotating friction force of the rotating shaft 8 is increased, and the rotating gear column cannot rotate easily and can only rotate under the driven condition.

As shown in fig. 1 and 3, a clamping piece groove 13 for limiting the driving part 7 is formed on the inner wall of the fixed lamp holder 1;

the driving part 7 includes a rack block 71 disposed along an inner wall of the card slot 13, and the rack block 71 can be inserted into the catching slot 524.

When the balloon seat 31 pushes the lamp tube 2 to extend out of the fixed lamp holder 1 (in a daily situation, the rack block 71 is also inserted into the embedding groove 524, and only then the purpose of driving the sliding belt 521 to move is met), at this time, the embedding groove 524 on the sliding belt 521 is pushed by the rack block 71 to gradually move counterclockwise around the supporting rack 522, and in the process of counterclockwise movement of the sliding belt 521, the driving rack group 523 drives the driving rack group 523 to move from the top end of the lamp tube 2 to one side of the fixed lamp holder 1 so as to sequentially rotate the driving rack 51 until the balloon seat 31 pushes the lamp tube 2 to fully extend out of the fixed lamp holder 1.

The movement principle of the rack block 71 and the sliding belt 521 is equivalent to that of a gear and a rack, the rack is fixed, and the sliding belt 521 is pushed downwards by the rack block 71 when upward traction is applied to the supporting tooth column 522.

As shown in fig. 1, 2, 3, 4 and 5, a thickened belt 525 is mounted on the surface of the sliding belt 521, the thickened belt 525 can push the sliding clamping column 61 to slide out of the clamping groove 63, and an inclined surface is arranged at the end of the thickened belt 525;

the surface of the sliding clamping column 61 is provided with an auxiliary lug 64;

the width of the thickening belt 525 is not smaller than the width of the card slot 13.

The specific structure of the sliding belt 521 is not exclusive, but the sliding belt 521 in this embodiment can realize the action of sliding the sliding clamping column 61 out of the clamping groove 63, and the structure of the auxiliary lug 64 in this embodiment can be as shown in fig. 4, when the sliding belt 521 moves counterclockwise, the inclined surface of the thickened belt 525 contacts the auxiliary lug 64 one step before, and then the auxiliary lug 64 pushes the sliding clamping column 61 to move away from the sliding belt 521 and compress the pushing member 62 until the sliding clamping column 61 slides out of the clamping groove 63.

And the thickened belt 525 can also limit the maximum process that the balloon seat 31 pushes the lamp tube 2 to extend, namely when the thickened belt 525 slides to the block contact card groove 13, the thickened belt 525 can block the card groove 13 and cannot pass through the card groove 13, thereby preventing the lamp tube 2 from extending and transiting.

As shown in fig. 1, 2 and 3, the rotating shaft 8 includes a bearing rotating shaft 81 connected to the inner wall of the installation cavity, a driven rotating sleeve 82 is sleeved on the side wall of the bearing rotating shaft 81, a position corresponding to the lamp post on the surface of the driven rotating sleeve 82 is provided with a clamping sliding groove 83, two ends of the driven rotating sleeve 82 are both connected with secondary tooth posts 84, and the lamp post is also installed on the surface of the driven rotating sleeve 82;

a widening strip 527 is installed on the side wall of the sliding belt 521, and a secondary column hole 526 meshed with the secondary tooth column 84 is formed in the surface of the widening strip 527;

the length of the widening bar 527 is not less than the pitch between the plurality of rotation shafts 8 and the widening bar 527 is provided on the side of the slide belt 521 near the air cylinder 822.

The specific structure of the rotating shaft 8 is not unique, but the light of the sterilizer in the prior art is emitted by a strand of ultraviolet lamp, and if the irradiation angle of the sterilizer is forcibly adjusted, the irradiation range is easily not large enough, so that the rotating shaft 8 in the embodiment can be preferably used for adjusting the irradiated light without affecting the irradiation range.

In specific implementation, whether the irradiation range and the irradiated light are considered simultaneously or only the irradiated light is required to be adjusted according to actual conditions.

Simultaneously, the irradiation range and the irradiated light are considered for adjustment: at this time, it is necessary to control the passive rotating sleeve 82 not to rotate along with the bearing rotating shaft 81, that is, to control the air cylinder 822 to be inactive, when the sliding belt 521 moves counterclockwise, the driving tooth group 523 directly drives the driving tooth post 51 and the bearing rotating shaft 81 to rotate, and at the same time, the widening bar 527 also moves, and then, when the secondary post hole 526 on the widening bar 527 contacts the secondary tooth post 84, because the passive rotating sleeve 82 is limited by the air cylinder 822, when the secondary post hole 526 contacts the secondary tooth post 84, the secondary tooth post 84 is pushed by the widening bar 527 to incline, and after the secondary tooth post 84 is separated from the secondary post hole 526, the secondary tooth post 84 is driven to correct by the right spring 841.

In the above operation, the rotation angle of the lamp post on the driven rotating sleeve 82 is not changed, and only the lamp post on the bearing rotating shaft 81 is changed, so that the purpose of adjusting the irradiation range and the irradiated light is satisfied.

In this embodiment, the depth of the secondary post hole 526 is greater than the thickness of the driven rotating sleeve 82, and the number of the secondary post holes 526 is the same as the number of the teeth in the driving teeth 523, and the set positions are also corresponding to each other, so that the rotation angles of the lamp post on the bearing rotating shaft 81 and the lamp post on the driven rotating sleeve 82 are the same.

Only the irradiated light is adjusted: that is to say, need to open air washed section of thick bamboo 822, after air washed section of thick bamboo 822 is released, in case slip belt 521 drives tooth group 523 and has contacted drive tooth post 51, then bear pivot 81 and just can rotate, secondary post hole 526 on the widening strip 527 also can contact secondary tooth post 84 simultaneously for passive commentaries on classics cover 82 rotates, and the existence of screens spout 83 can play the purpose of restricting the turned angle of passive commentaries on classics cover 82, makes passive commentaries on classics cover 82 can not rotate excessively.

As shown in fig. 1 and 4, a limiting groove 821 is formed on the surface of the driven rotating sleeve 82, an air impact cylinder 822 is installed at a position corresponding to the limiting groove 821 on the inner wall of the installation cavity, a pushing sealing column 823 is connected in the air impact cylinder 822, a blocking column 824 which penetrates through the air impact cylinder 822 and extends into the limiting groove 821 is installed at one end of the pushing sealing column 823, and a return spring 825 which is connected with the inner wall of the air impact cylinder 822 is installed at the other end of the pushing sealing column 823; the air cylinder 822 can introduce air into the inflatable bag seat 31 to guide the push seal 823 and block the movement of the column 824 in the air cylinder 822 in a direction away from the limit groove 821.
