[0001] The present invention relates to the technical field of air purifiers, in particular to an air disinfecting and purifying machine. Background Art

[0002] With the increasing severity of air pollution and the continuous improvement of people's living standards, air purifiers are used more and more widely. For example, air purifiers can clean the air indoors and in cars to prevent people from inhaling harmful gases, which would endanger people's safety.

[0003] However, the existing air purifiers have complex structures, single functions, high energy consumption, and only have a passive purification mode, which is difficult to meet people's needs. For this reason, we propose an air disinfection and purification machine. Summary of the invention

[0004] The main purpose of the present invention is to provide an air disinfection and purification machine with a simple structure, diverse functions, low energy consumption, and a mode combining active disinfection and passive purification, so as to solve the deficiencies raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an air disinfection and purification machine, comprising an outer cover, a cover, a passive purification device and an active purification device for releasing a disinfection medium, wherein the cover is arranged in front of the outer cover and a first air outlet is formed therebetween, an air inlet is arranged at the rear of the outer cover, and a passage connecting the air inlet and the first air outlet is arranged inside the outer cover; the passive purification device comprises a fan and a physical filter module, and the fan, the physical filter module and the active purification device are installed in the passage in sequence from back to front.

[0006] The beneficial effects of the present invention are as follows: the present invention has a simple structure and a reasonable layout; it can turn on the fan to suck air from the air inlet into the channel, and the sucked air is filtered by the physical filter module and then discharged from the first air outlet, thereby achieving the purpose of passive air purification; it can also turn on the active purification device to release the disinfection medium to disinfect the air, thereby achieving the purpose of disinfection, active deodorization, and active formaldehyde removal, and further achieving the purpose of active air purification; a dual purification function is achieved by combining active purification and passive purification, thereby achieving the dual purification functions of active disinfection, active deodorization, active formaldehyde removal, freshness preservation and physical interception of particulate matter, which greatly increases the applicability of the product.

[0007] Preferably, it also includes a control system, the control system includes an intelligent display screen, electronic components and function buttons, the intelligent display screen, electronic components, function buttons, active purification device and fan are electrically connected; the intelligent display screen and electronic components are installed inside the outer cover, the function buttons are installed on the cover, and the cover is provided with an opening for observing the intelligent display screen. The advantage is that intelligent control can be achieved through the control system.

[0008] Preferably, a transparent display screen cover is provided on the opening, which has the advantage of protecting the smart display screen and extending the service life of the smart display screen.

[0009] Preferably, the front of the cover and the outer circumference surrounding the opening are integrally recessed backward to form an annular receiving groove, a light strip electrically connected to the function button is arranged in the receiving groove, and a lampshade is provided on the receiving groove. The advantages are: on the one hand, when the air disinfection and purification machine is installed on the wall, the light strip can play the role of a wall lamp, and the functions are more diversified. On the other hand, under the effect of the receiving groove, the installation of the light strip will not appear abrupt, which greatly improves its overall aesthetics. In addition, the lampshade can protect the light strip and extend the service life of the light strip; in addition, the lampshade can also play an anti-glare role.

[0010] Preferably, the front of the cover is located between the receiving groove and the opening and is integrally recessed to form an annular mounting groove, and tooth blocks are integrally protruded at equal intervals in the mounting groove, and the root of the tooth block is provided with a second air outlet connected to the channel. The advantages are: under the action of the tooth block, the overall aesthetics is further improved; and under the action of the second air outlet, the air throughput of the air disinfection and purification machine is greatly improved; in addition, compared with the single first air outlet, after adding the second air outlet, the size of the first air outlet can be greatly reduced, which is conducive to making the gap between the outer cover and the cover smaller, and further conducive to preventing dust from entering.

[0011] Preferably, the physical filter module includes a first filter screen made of a combined sponge and a second filter screen made of a combined filter paper, and the first filter screen and the second filter screen are stacked and arranged in the channel from back to front. The advantages are: on the one hand, the first filter screen made of the combined sponge and the second filter screen made of the combined filter paper can physically filter the air entering the channel, intercept the particulate matter in the air, and output pure air; on the other hand, because the material of the first filter screen is the combined sponge, its special porous structure can absorb the noise generated when the fan is working.

[0012] Preferably, the active purification device is a plasma generator, which is installed in the channel and embedded in the second filter. The advantage is that the plasma generator can increase the input 12V voltage to 7000V through voltage transformation to discharge the air, thereby generating active oxygen O3 molecules for active sterilization and disinfection, thereby killing viruses and bacteria in the air, blocking the risk of infectious diseases, and removing various odors, formaldehyde, mold, etc. In addition, the plasma generator is embedded in the second filter, which is conducive to reducing the overall volume of the purifier.

[0013] Preferably, a first annular mounting surface for fitting the first filter screen and a second annular mounting surface for fitting the second filter screen are integrally formed in the channel, and the radial dimension of the second annular mounting surface is larger than the radial dimension of the first annular mounting surface. The advantages are: since the air flows from the first filter screen to the second filter screen, and since the pores of the combined sponge are large, the air flow rate is large, while the pores of the combined filter paper are small, the air flow rate is small; therefore, when the radial dimension of the second annular mounting surface is larger than the radial dimension of the first annular mounting surface, the radial dimension of the second filter screen is larger than the radial dimension of the first filter screen, so as to ensure a stable air flow rate in the channel; in addition, if the assembly gap between the first filter screen and the first annular mounting surface and between the second filter screen and the second annular mounting surface is too large, when the radial dimension of the second filter screen is larger than the radial dimension of the first filter screen, it is also helpful to avoid air passing through the channel directly through the gap between them.

[0014] Preferably, a fixing plate is installed behind the cover, and a pressing block for preventing the second filter from falling off is integrally protruded behind the fixing plate. The advantage is that under the action of the fan, the air is blown from the direction of the first filter to the direction of the second filter, and the first filter and the second filter both have a blocking effect on the circulating air, so the circulating air can easily blow out the first filter and the second filter, and under the limit of the pressing block, the first filter and the second filter can be prevented from being blown out.

[0015] Preferably, a hollow mounting frame with an open lower end is provided at the rear end of the outer cover, and a through hole for connecting the air inlet and the interior of the mounting frame is provided on the mounting frame.

The passive purification device 3 includes a fan 31 and a physical filter module 32. The fan 31, the physical filter module 32, and the active purification device 4 are sequentially installed in the channel 12 from back to front. After the fan 31 is turned on, air can be sucked into the channel 12 from the air inlet 11, and the sucked air is filtered by the physical filter module 32 and discharged from the first air outlet 10, thereby achieving the purpose of passive air purification. After the active purification device 4 is turned on, the disinfection medium released by it can disinfect the air, thereby achieving the purpose of disinfection and sterilization, active deodorization, and active formaldehyde removal, thereby achieving the purpose of active air purification.

[0023] In this embodiment, in order to facilitate intelligent control, a control system 5 can also be provided, the control system 5 includes an intelligent display screen 51, electronic components 52 and function buttons (the function buttons are not shown in the attached drawings), the intelligent display screen 51, electronic components 52, function buttons, active purification device 4 and fan 31 are electrically connected; the intelligent display screen 51 and electronic components 52 are installed inside the outer cover 1, the function buttons are installed on the cover 2, and the cover 2 is provided with an opening 21 for observing the intelligent display screen 51. By operating the function buttons and observing the intelligent display screen 51, the working state (start / stop / automatic), working mode (active mode / passive mode), wind speed, etc. of the purifier can be changed.

[0024] In this embodiment, a transparent display screen cover plate 6 is provided on the opening 21 to protect the smart display screen 51 and extend the service life of the smart display screen 51 .

[0025] In this embodiment, the front of the cover 2 and the outer circumference surrounding the opening 21 are integrally recessed backward to form an annular receiving groove 22, and a light strip electrically connected to the function button is arranged in the receiving groove 22 (the light strip is not shown), and a lampshade 7 is provided on the receiving groove 22. When the air disinfection and purification machine is installed on the wall, the light strip can play the role of a wall lamp, and the functions are more diversified. In addition, under the action of the receiving groove 22, the installation of the light strip will not appear abrupt, which greatly improves its overall aesthetics. In addition, the lampshade 7 can protect the light strip and extend the service life of the light strip; in addition, the lampshade 7 can also play an anti-glare role.

[0026] In this embodiment, the front of the cover 2 is located between the receiving groove 22 and the opening 21 and is integrally recessed to form an annular mounting groove 23, and tooth blocks 24 are integrally protruded at equal intervals in the mounting groove 23. The root of the tooth block 24 is provided with a second air outlet 25 (such as Figure 3 As shown). Under the action of the tooth block 24, the overall aesthetics is further improved. Under the action of the second air outlet 25, the air throughput of the air disinfection and purification machine is greatly improved; and, compared with the single first air outlet 10, when the second air outlet 25 is added, the size of the first air outlet 10 can be greatly reduced, which is conducive to making the gap between the outer cover 1 and the cover 2 smaller, and further conducive to preventing dust from entering.

[0027] In this embodiment, the physical filter module 32 includes a first filter screen 321 made of a combined sponge and a second filter screen 322 made of a combined filter paper, and the first filter screen 321 and the second filter screen 322 are sequentially stacked from back to front in the channel 12. On the one hand, the first filter screen 321 made of a combined sponge and the second filter screen 322 made of a combined filter paper can physically filter the air entering the channel 12, intercept the particulate matter in the air, and output pure air; on the other hand, since the material of the first filter screen 321 is a combined sponge, its special porous structure can absorb the noise generated when the fan 31 is working, thereby playing a noise reduction role.

[0028] In this embodiment, the active purification device 4 is preferably a plasma generator, which is installed in the channel 12 and embedded in the second filter 322. The plasma generator can increase the input 12V voltage to 7000V through a voltage transformer to discharge the air, so as to produce active oxygen O3 molecules for active sterilization and disinfection, thereby killing viruses and bacteria in the air, blocking the risk of infectious diseases, and removing various odors, formaldehyde, mold, etc. In addition, the plasma generator is embedded in the second filter 322, which is conducive to reducing the overall volume of the purifier. Among them, the generating head of the plasma generator adopts 5 layers of nano-ceramic protection technology to ensure the durability of the product (its release durability is continuously used for 8000 hours). Moreover, the product is designed and manufactured in accordance with the national GB4706 household appliance safety standard. The plasma generator uses 12V voltage to draw electricity, which is increased to 7000V through transformer to ensure zero risk of high-voltage discharge of the product; at the same time, the circuit integrated board uses filling technology to ensure that the disinfection module has waterproof, flame retardant, fireproof, anti-electric shock, and durable characteristics. In addition, through the use of current technology control and software programming technology, the disinfection module can accurately control the production of active oxygen O3 molecules for low-concentration sterilization and disinfection at 1 to 80mg / h, thereby realizing the use of low-concentration, human-machine coexistence, and disinfection and sterilization disinfection modules to kill viruses and bacteria in the air, block the risk of infectious diseases, and remove various odors and formaldehyde, mold, and environmentally friendly preservation solutions.

[0029] In this embodiment, a first annular mounting surface 13 for fitting the first filter screen 321 and a second annular mounting surface 14 for fitting the second filter screen 322 are integrally formed in the channel 12 , and the radial dimension of the second annular mounting surface 14 is greater than the radial dimension of the first annular mounting surface 13 . Since the air flows from the first filter screen 321 to the second filter screen 322, and since the pores of the combined sponge are large, the air flow rate is large, while the pores of the combined filter paper are small, the air flow rate is small; therefore, when the radial dimension of the second annular mounting surface 14 is larger than the radial dimension of the first annular mounting surface 13, the radial dimension of the second filter screen 322 is larger than the radial dimension of the first filter screen 321, so as to ensure a stable air flow rate in the channel 12; in addition, if the assembly gaps between the first filter screen 321 and the first annular mounting surface 13 and between the second filter screen 322 and the second annular mounting surface 14 are too large, when the radial dimension of the second filter screen 322 is larger than the radial dimension of the first filter screen 321, it is also beneficial to avoid air passing through the channel 12 directly through the gap between them.

[0030] In this embodiment, a fixing plate 8 is installed at the rear of the cover 2, and a pressing block 81 is integrally protruded at the rear of the fixing plate 8 for preventing the second filter 322 from falling off. Under the action of the fan 31, air is blown from the direction of the first filter 321 to the direction of the second filter 322, and the first filter 321 and the second filter 322 both have a blocking effect on the circulating air, so the circulating air can easily blow out the first filter 321 and the second filter 322, and under the limit of the pressing block 81, the first filter 321 and the second filter 322 can be prevented from being blown out.

[0031] In this embodiment, the fan 31 includes a motor 311 and a fan 312. The motor 311 is installed in the channel 12 through a motor fixing plate 8313, and the fan 312 is installed on the output shaft of the motor 311 (such as Figure 5 The motor fixing plate 8313 cannot block the air flow in the channel 12, and can be a cross, a cross, or a porous structure, etc., to avoid blocking the channel 12. In addition, a protective cover can be provided on the outside of the fan 312 (the protective cover is not shown).

[0032] In this embodiment, a mounting frame 9 having a hollow structure and an open lower end is provided at the rear end of the outer cover 1. The mounting frame 9 can be fixed to the wall by screws, so that the purifier is installed on the wall; and because the upper end of the mounting frame 9 is closed, dust can be prevented from falling into the air inlet 11. The mounting frame 9 is provided with a through hole 91 for connecting the air inlet 11 and the inside of the mounting frame 9. After the fan 31 is started, air can be sucked into the mounting frame 9 through the bottom of the mounting frame 9 and enter the air inlet 11 from the through hole 91.

[0033] Here’s how it works:

[0034] Active mode: When powered on, the plasma generator is started through the function button. The plasma generator increases the input 12V voltage to 7000V through voltage transformation to discharge the air, releasing active oxygen O3 molecules for active sterilization and disinfection, thereby killing viruses and bacteria in the air, blocking the risk of infectious diseases, and removing various odors, formaldehyde, mold, etc. in the air.

[0035] Passive mode: The motor 311 is started, and the fan 312 is able to draw in external air, and physically filter it through the first filter 321 and the second filter 322 to remove particulate impurities in the air, thereby outputting pure air into the room.

[0036] The present invention adopts a dual purification mode combining an active mode and a passive mode, that is, a design scheme combining active disinfection and physical interception. This enables the product to fundamentally solve the concept of combining air disinfection and purification, thereby truly blocking the cross-infection of infectious diseases and also having the function of purifying air PM2.5.

[0037] The above description is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
