Description

Technical Field

[0001] The present invention belongs to the technical field of air sterilization, and particularly relates to an air sterilization and purification integrated machine. Background Art

[0002] An air sterilization and purification integrated machine is a machine that disinfects air through principles such as filtration, purification, and sterilization. Existing air purification often removes odors from the air through an activated carbon filter screen to achieve the purpose of purification. For air sterilization, there are many principles, and existing air sterilization uses ultraviolet lamp sterilization, photocatalyst mesh sterilization, ion generator sterilization, ozone generator sterilization, etc.; among them, ultraviolet lamp sterilization has the advantage of low production cost, so it is produced and used more.

[0003] However, during the long-term use of the ultraviolet lamp tube, a layer of dust will adhere to the surface of the ultraviolet lamp tube, which easily blocks the ultraviolet irradiation, reduces the ultraviolet irradiation received by the bacteria entering the machine body with the air, thus reducing the sterilization effect of the ultraviolet ray. And when cleaning the ultraviolet lamp tube, the staff needs to turn off the power of the entire machine and then take out the ultraviolet lamp tube for cleaning. During the cleaning process, the ultraviolet lamp tube cannot operate normally, thereby reducing the sterilization efficiency of the ultraviolet lamp tube.

[0027] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0028] As Figures 1 to 4 shown, an air sterilization and purification all-in-one machine according to the present invention includes:

[0029] A body 1, one end of the body 1 is provided with an installation opening 11, and the other end is fixedly installed with a ventilation fan 12; an installation plate 2 is slidably installed on the inner wall of the body 1; an ultraviolet lamp tube 21 is provided between the installation plate 2 and the ventilation fan 12; the ultraviolet lamp tube 21 is detachably installed on the installation plate 2; the inner wall of the installation opening 11 is threadedly connected with a filter screen 13;

[0030] A cleaning mechanism, the cleaning mechanism is installed on one side of the installation plate 2 close to the ventilation fan 12; the cleaning mechanism is located at the center of the installation plate 2; the cleaning mechanism is used for cleaning the ultraviolet lamp tube 21;

[0031] A controller, the controller is used to control the automatic operation of the entire air sterilization and purification all-in-one machine;

[0032] In the prior art, during the long-term use of the ultraviolet lamp tube 21, a layer of dust will adhere to the surface of the ultraviolet lamp tube 21, which easily blocks the ultraviolet irradiation, resulting in a reduction in the ultraviolet irradiation received by the bacteria entering the body 1 with the air, thereby reducing the sterilization effect of the ultraviolet ray. Moreover, when cleaning the ultraviolet lamp tube 21, the staff needs to turn off the power of the entire machine and then take out the ultraviolet lamp tube 21 for cleaning. During the cleaning process, the ultraviolet lamp tube 21 cannot operate normally, thereby reducing the sterilization efficiency of the ultraviolet lamp tube 21;

[0033] During operation, the staff controls the operation of the ventilation fan 12 and the ultraviolet lamp 21 through the controller, so that the ventilation fan 12 discharges the air in the body 1, making the inside of the body 1 in a negative pressure state, and enabling the outside air to enter the body 1 through the installation port 11 of the body 1. During the process of air entering the installation port 11, the air will be filtered by the filter screen 13, so that large solid impurities in the air are filtered by the filter screen 13, thereby purifying the air. The air entering the body 1 is irradiated by the ultraviolet lamp 21, so that bacteria and other microorganisms in the air die under the radiation of the ultraviolet lamp 21, and bacteria and other tiny dust will fall on the ultraviolet lamp 21. And with long-term use, it is easy for dust to accumulate on the ultraviolet lamp 21, blocking the radiation of ultraviolet rays; Therefore, when the staff wants to clean the ultraviolet lamp 21, the cleaning mechanism is controlled by the controller to clean the dust accumulated on the ultraviolet lamp 21, so as to ensure the normal radiation of ultraviolet rays, and further improve the sterilization effect of the ultraviolet lamp 21;

[0034] Through the setting of the cleaning mechanism of the present invention, the cleaning mechanism cleans the dust accumulated on the surface of the ultraviolet lamp 21 without turning off the power supply, thereby avoiding the blockage of the ultraviolet rays released by the ultraviolet lamp 21 by the dust. Furthermore, the intensity of the radiation of the ultraviolet lamp 21 received by the bacteria entering the body 1 with the air is increased, and there is no need for the staff to turn off the power supply of the entire machine, ensuring that the ultraviolet lamp 21 is still in the sterilization state during the cleaning process, thereby improving the sterilization efficiency of the ultraviolet lamp 21 and enhancing the practicability of the present invention.

[0035] As an implementation manner of the present invention, the cleaning mechanism includes a support rod 22; a cleaning frame 3 is slidably connected to the support rod 22; a sponge sheet 31 is installed at one end of the cleaning frame 3 close to the ultraviolet lamp 21; the sponge sheet 31 is arc-shaped; the sponge sheet 31 is in sliding contact with the ultraviolet lamp 21; a driving module is installed on the mounting plate 2; the driving module is used to drive the cleaning frame 3 to move, so that the cleaning frame 3 drives the sponge sheet 31 to clean the ultraviolet lamp 21; an ash outlet 14 is opened below the body 1;

[0036] During operation, in the initial state, the ash outlet 14 is in the closed state. The cleaning rack 3 is driven by the driving module to be located at one end of the ultraviolet lamp tube 21 close to the mounting plate 2, and the sponge sheet 31 is always in sliding contact with the ultraviolet lamp tube 21. When it is necessary to clean the ultraviolet lamp tube 21, the controller controls the driving module to drive the cleaning rack 3 to move along the support rod 22 in the direction close to the ventilation fan 12, so that the cleaning rack 3 drives the sponge sheet 31 to push the dust accumulated on the surface of the ultraviolet lamp tube 21 towards the position of the ventilation fan 12, causing the dust on the ultraviolet lamp tube 21 to fall off the ultraviolet lamp tube 21 under the push of the sponge sheet 31 and fall onto the inner wall of the machine body 1 below the ultraviolet lamp tube 21. When it is necessary to clean the dust in the machine head, the staff opens the ash outlet 14 and then uses tools to scrape the dust in the machine body 1 to the ash outlet 14, so that the dust falls from the ash outlet 14. After the dust in the machine body 1 is cleaned, the ash outlet 14 is closed again. Through the setting of the ash outlet 14, the staff can clean the dust in the machine body 1 from the ash outlet 14, so there is no need to disassemble and clean the air sterilization and purification machine, thereby reducing the labor intensity of the staff and improving the practicability of the present invention.

[0037] As an embodiment of the driving module of the present invention, the driving module includes a lead screw-slider pair 32; a bracket 33 is fixedly connected to the inner wall of the machine body 1; one end of the lead screw of the lead screw-slider pair 32 is rotatably connected to the mounting plate 2, and the other end is rotatably connected to the bracket 33; the cleaning rack 3 is helically connected to the lead screw of the lead screw-slider pair 32; a driving motor 34 is fixedly installed on one side of the mounting plate 2 close to the filter screen 13; the output end of the driving motor 34 is fixedly connected to the lead screw of the lead screw-slider pair 32;

[0038] During operation; the support rod 22 serves as the smooth rod of the lead screw-slider pair 32; when the staff needs to clean the ultraviolet lamp tube 21, the staff controls the driving motor 34 to drive the lead screw to rotate through the controller, so that the lead screw drives the cleaning rack 3 to move along the support rod 22 in the direction close to the ventilation fan 12, causing the cleaning rack 3 to drive the sponge sheet 31 to push the dust accumulated on the surface of the ultraviolet lamp tube 21 to fall off the ultraviolet lamp tube 21. By setting the driving module as the lead screw-slider pair 32 in the present invention, the sponge sheet 31 driven by the lead screw-slider pair 32 scrapes the dust on the ultraviolet lamp tube 21 more smoothly and accurately. And by controlling the driving motor 34 to rotate in the reverse direction, the driving motor 34 drives the lead screw to drive the cleaning rack 3 to move away from the ventilation fan 12, so that the mounting rack drives the sponge sheet 31 to reset, and the sponge sheet 31 cleans the ultraviolet lamp tube 21 again during the reset process, thereby improving the cleaning effect of the sponge sheet 31 and enhancing the practicability of the present invention.

[0039] As another embodiment of the driving module of the present invention, the driving module includes a first steel wire rope 35; on one side of the mounting plate 2 close to the filter screen 13, a driving motor 34 is fixedly installed; one end of the steel wire rope is fixedly connected to one side of the cleaning frame 3 close to the mounting plate 2, and the other end passes through the mounting plate 2 and is fixedly connected to the output shaft of the driving motor 34; on one side of the cleaning frame 3 away from the mounting plate 2, a spring is fixedly connected; one end of the spring away from the cleaning frame 3 is fixedly connected to the inner wall of the machine body 1;

[0040] During operation; in the initial state, the mounting frame is located at one end of the ultraviolet lamp tube 21 close to the ventilation fan 12. When the staff needs to clean the ultraviolet lamp tube 21, the staff controls the driving motor 34 to rotate through the controller, so that the steel wire rope pulls the cleaning frame 3 to move in the direction close to the mounting plate 2, so that the cleaning frame 3 pulls the spring to stretch, so that the cleaning frame 3 drives the sponge sheet 31 to slide along the surface of the ultraviolet lamp tube 21, so that the sponge sheet 31 scrapes off the dust on the surface of the ultraviolet lamp tube 21, so that the dust accumulated on the surface of the ultraviolet lamp tube 21 falls off from the ultraviolet lamp tube 21 under the scraping of the sponge sheet 31. When the dust on the ultraviolet lamp tube 21 needs to be cleaned again, the controller controls the driving motor 34 to rotate in the reverse direction, so that the driving motor 34 continuously releases the steel wire rope. At this time, the cleaning frame 3 moves in the direction close to the ventilation fan 12 under the pulling force of the restoring force of the stretched spring. Since the cleaning frame 3 is pulled by the steel wire rope, the moving speed of the cleaning frame 3 is consistent with the speed at which the driving motor 34 releases the steel wire rope, avoiding the cleaning frame 3 hitting the ventilation fan 12 due to inertia when the spring pulls the cleaning frame 3 to move to the end of the support frame away from the mounting plate 2, ensuring that the ventilation fan 12 is not hit by the cleaning frame 3, improving the service life of the ventilation fan 12, and improving the practicability of the present invention.

[0041] As an implementation manner of the present invention, it is characterized in that: two sponge sheets 31 are provided on both sides of each ultraviolet lamp tube 21; on the side of the sponge sheet 31 away from the ultraviolet lamp tube 21, a shell 4 made of PTFE material is fixedly installed; one end of the shell 4 is rotatably installed on the cleaning frame 3 through a torsion spring 41; a stretching module is installed on the cleaning frame 3; the pushing module is used to pull the two sponge sheets 31 to open;

[0042] During operation; in the initial state, the stretching module is in the closed state. At this time, the two sponge pieces 31 located on both sides of the ultraviolet lamp tube 21 are attached to the surface of the ultraviolet lamp tube 21. The controller controls the driving module to drive the cleaning rack 3 to drive the two sponge pieces 31 to move towards the other end of the ultraviolet lamp tube 21, so that the sponge pieces 31 push the dust on the ultraviolet lamp tube 21 to move along the surface of the ultraviolet lamp tube 21 towards the other side of the ultraviolet lamp tube 21. When the sponge pieces 31 push the dust on the surface of the ultraviolet lamp tube 21 to move to the other end of the ultraviolet lamp tube 21, the controller controls the stretching module to pull the outer shell 4 to rotate away from the ultraviolet lamp tube 21 against the torsion of the torsion spring 41, so that the two outer shells 4 open, thereby causing the outer shell 4 to drive the two sponge pieces 31 to move away from each other. During the process of the sponge pieces 31 opening, the dust scraped by the sponge pieces 31 on the surface of the ultraviolet lamp tube 21 accumulates, and the dust blocked by the body 1 at one end of the ultraviolet lamp is shoveled off by the rotation of the sponge pieces 31, so that the rotating outer shell 4 drives the sponge pieces 31 to shovel the dust blocked by the body 1 away from the upper surface of the ultraviolet lamp, thereby improving the cleaning effect of the sponge pieces 31 and enhancing the practicability of the present invention.

[0043] As an embodiment of the present invention, the stretching module includes a slider 42; a groove 36 is formed on the cleaning rack 3; the slider 42 is slidably connected in the groove 36; a second steel wire rope 43 is fixedly connected to the slider 42; the end of the second steel wire rope 43 away from the slider 42 is fixedly connected to the outer shell 4; an electromagnet 44 is fixedly connected to the bottom of the groove 36; the slider 42 is made of iron material;

[0044] During operation; in the initial state, the slider 42 is located at the notch end of the groove 36 under the pulling of the steel wire rope; when the sponge piece 31 pushes the dust on the surface of the ultraviolet lamp tube 21 to move to the other end of the ultraviolet lamp tube 21, the controller controls the electromagnet 44 to be energized, so that the electromagnet 44 generates a magnetic force and adsorbs the slider 42 to slide towards the bottom of the groove 36, so that the slider 42 pulls the outer shell 4 through the steel wire rope to move away from the ultraviolet lamp tube 21 against the torsion of the torsion spring 41, so that the slider 42 pulls the outer shell 4 through the second steel wire rope 43 to rotate away from the ultraviolet lamp tube 21 against the torsion of the torsion spring 41, so that the outer shell 4 drives the sponge piece 31 to rotate away from the ultraviolet lamp tube 21; so that the rotating outer shell 4 drives the sponge piece 31 to shovel the dust blocked by the body 1 away from the upper surface of the ultraviolet lamp; when the cleaning is completed, the controller controls the electromagnet 44 to be powered off, so that the outer shell 4 rotates towards the ultraviolet lamp tube 21 under the action of the restoring force of the torsion spring 41. During the rotation of the outer shell 4, the outer shell 4 can pull the slider 42 away from the electromagnet 44 through the second steel wire rope 43, so that the slider 42 is reset.

[0045] As an embodiment of the present invention, a semicircular groove 36 is formed on the surface of the sponge piece 31 close to the ultraviolet lamp tube 21; the diameter of the groove 36 is the same as the diameter of the ultraviolet lamp tube 21;

[0046] During operation, by providing a semi-circular groove 36 on one side of the sponge sheet 31 close to the ultraviolet lamp tube 21, the ultraviolet lamp tube 21 in the initial state is located within the semi-circular grooves 36 of the two sponge sheets 31. At this time, the two sponge sheets 31 wrap the ultraviolet lamp tube 21 in the vertical cross-section direction through the concave surfaces of the semi-circular grooves 36. When the two sponge sheets 31 move along with the cleaning frame 3, the sponge sheets 31 can clean the entire cylindrical surface of the ultraviolet lamp tube 21, increasing the cleaning area of the sponge sheets 31 for the ultraviolet lamp tube 21 and improving the cleaning effect of the sponge sheets 31 on the ultraviolet lamp tube 21; thus, the practicality of the present invention is further enhanced.

[0047] As an implementation manner of the present invention, a card slot 45 is provided on one side of the housing 4 close to the lamp tube; a T-shaped block 311 is fixedly installed on the side of the sponge sheet 31 away from the ultraviolet lamp tube 21; the T-shaped block 311 is inserted into the card slot 45; a cleaning port 15 is provided on the outer wall of the machine body 1; the cleaning port 15 is directly opposite to the lamp tube; a baffle 16 is slidably and sealingly connected to the inner wall of the cleaning port 15;

[0048] During operation, since the sponge sheet 31 is used multiple times, dust will accumulate on the sponge sheet 31, causing the surface of the sponge sheet 31 to be contaminated by dust, thereby affecting the cleaning effect of the sponge sheet 31 on the dust on the surface of the ultraviolet lamp tube 21. Therefore, the sponge sheet 31 needs to be replaced after long-term use; when the sponge sheet 31 needs to be replaced, the staff controls the ultraviolet lamp tube 21 to turn off through the controller, and at the same time controls the stretching module to pull the two housings 4 apart, then removes the baffle 16 at the cleaning port 15. At this time, the sponge sheet 31 installed on the housing 4 can be seen from the cleaning port 15. The staff uses tools to pull out the sponge sheet 31, so that the sponge sheet 31 drives the T-shaped block 311 to slide along the card slot 45, causing the sponge sheet 31 to drive the T-shaped block 311 to be pulled out from the card slot 45 of the housing 4 and replace the sponge sheet 31. After the replacement is completed, the baffle 16 at the cleaning port 15 is covered; by providing the baffle 16 to be slidably and sealingly connected at the cleaning port 15, the baffle 16 can seal the cleaning port 15, thereby ensuring that after the ventilation fan 12 extracts the air in the machine body 1, the outside gas can only enter from the installation port 11, thereby improving the ventilation effect of the ventilation fan 12 and further improving the actual application effect of the present invention.

[0049] The specific working process is as follows:

[0050] The staff controls the operation of the ventilation fan 12 and the ultraviolet lamp 21 through the controller, so that the ventilation fan 12 discharges the air in the body 1, making the inside of the body 1 in a negative pressure state, and enabling the outside air to enter the body 1 through the installation port 11 of the body 1. During the process of air entering the installation port 11, the air will be filtered by the filter screen 13, so that large solid impurities in the air are filtered by the filter screen 13, thereby purifying the air. The air entering the body 1 is irradiated by the ultraviolet lamp 21, causing bacteria and other microorganisms in the air to die under the radiation of the ultraviolet lamp 21, and bacteria and other tiny dust will fall onto the ultraviolet lamp 21. And with long-term use, dust is likely to accumulate on the ultraviolet lamp 21, blocking the radiation of ultraviolet rays; therefore, when the staff needs to clean the ultraviolet lamp 21, the controller controls the cleaning mechanism to clean the dust accumulated on the ultraviolet lamp 21, thus ensuring normal ultraviolet radiation and further improving the sterilization effect of the ultraviolet lamp 21; in the initial state, the ash outlet 14 is in a closed state, and the cleaning rack 3 is located at one end of the ultraviolet lamp 21 close to the mounting plate 2 driven by the driving module, and the sponge sheet 31 is always in sliding contact with the ultraviolet lamp 21; when it is necessary to clean the ultraviolet lamp 21, the controller controls the driving module to drive the cleaning rack 3 to move along the support rod 22 in the direction close to the ventilation fan 12, so that the cleaning rack 3 drives the sponge sheet 31 to push the dust accumulated on the surface of the ultraviolet lamp 21 towards the position of the ventilation fan 12, making the dust on the ultraviolet lamp 21 fall off from the ultraviolet lamp 21 under the push of the sponge sheet 31, and the dust falls onto the inner wall of the body 1 below the ultraviolet lamp 21. When it is necessary to clean the dust in the machine head, the staff opens the ash outlet 14 and then uses tools to scrape the dust in the body 1 to the ash outlet 14, so that the dust falls from the ash outlet 14. After the dust in the body 1 is cleaned, the ash outlet 14 is closed again.
