the first embodiment is as follows:
when purifier air-purifying, air admission purifier's purification module 2, remove dust and detach harmful substance after in purification module 2, by purification module 2 air duct 11 in getting into purifier's casing 1, then discharge by air duct 11, the air is a non-visual process at the process that purification module 2 purified, so the effect user after the air purification can not audio-visual experience, and purification module 2 uses after a period, purification performance can the variation, if the user is not in time to purification module 2 business turn over handles, can influence indoor air quality. The downstream air channel comprises a space for exhausting air treated by the purification module under the condition of air flow, and at least comprises a space at the periphery of the air outlet. The purifier with light source of this embodiment provides a visual and visual purifier of purifying effect, and the air after purification module 2 purifies when discharging, and the user can audio-visually see purifying effect to after purifier's purification performance variation, the user also can be through observing the dust quantity in the air that purifies 2 exhalations and judge, can make the user in time handle purification module 2, can not influence indoor air quality.
Referring to fig. 1 and 2, in this embodiment, the purification apparatus with a light source includes a housing 1, an air duct 11 and a purification module 2, the air duct 11 and the purification module 2 are disposed in the housing 1, the indoor air firstly enters the purification module 2, the air purified by the purification module 2 enters the air duct 11, and then is discharged into the room through the air duct 11, in order to make the effect of the purification module 2 on the purified air intuitive and visible, a first light source 3 for irradiating the air duct cavity is disposed in the air duct 11 at the downstream of the purification module 2, the projection position of the first light source 3 is a light-tight wall, and the housing 1 is provided with a light channel for observing the first light source 3 from the outside of the housing 1 to irradiate the air duct cavity.
That is, the air purified by the purification module 2 enters the air duct 11 and flows along the air duct 11, in the flowing direction of the air, the part of the air which just enters the air duct 11 is called as the upstream of the air duct 11, the part of the air which is to be discharged from the air duct 11 is the downstream of the air duct 11, the first light source 3 is arranged at the part of the air which is to be discharged from the air duct 11 or the air outlet of the air duct 11, when the first light source 3 is started, the light emitted by the first light source 3 is projected to the lighttight wall surface, at this time, the light emitted by the first light source 3 can be seen through the viewing channel, meanwhile, because the brightness of the light emitted by the first light source 3 is high, the dust in the air flow can be seen when the air flow passes through the light emitted by the first light source 3, the air flow is irradiated by the first light source 3, and the user can see the clearer dust particles in the range of the wind speed, thereby realizing the perception of the quality of the air treated by the purification module 2, if purification module 2 is better to the effect of air purification, the user can see through looking light passageway that less dust floats in the air current, if purification module 2 is not good to the purifying effect of air, or purification module 2's purification performance goes wrong, the user passes through looking light passageway this moment, can see that a lot of dust floats in the air current, the quantity of the dust that the user saw through looking light passageway can be as the foundation of judging purification module 2 to the purifying effect of air, make purification module 2 visual to the effect of air purification, and when purification module 2 function breaks down or life expires, the user also can be according to the dust quantity in the air after purification module 2 purifies in time discovery problem, and make corresponding processing to purification module 2.
It can be understood that the wall surface illuminated by the first light source 3 may be a portion of the housing 1 opposite to the first light source 3, or may be a wall surface separately disposed in the housing 1, in order to avoid light transmission of the first light source 3, when the wall surface illuminated by the first light source 3 is a portion of the housing 1 opposite to the first light source 3, the housing 1 needs to be made of a light-tight material, so that the light emitted by the first light source 3 does not pass through the housing 1; if the wall surface illuminated by the first light source 3 is an independent wall surface disposed in the housing 1, the wall surface illuminated by the first light source 3 in the housing 1 needs to be made of opaque material, and the light source and the reflected light from the reflected illumination portion thereof cannot pass through the wall surface.
Referring back to fig. 1 to 3, in order to prevent the user from stabbing the eyes of the user by the light emitted from the first light source 3 when observing the air purification effect and to make the user more easily observe the dust in the air flow, the light emitting surface of the first light source 3 forms an angle of 90 degrees with the air outlet direction, that is, when the air outlet direction is vertical and upward, the light emitting surface of the first light source 3 is horizontally disposed, when the first light source 3 emits light, the air flow vertically passes through the light emitted from the first light source 3, at this time, when the user observes the direction of the air flow, the line of sight of the user is opposite to the air flowing direction, the light emitted from the first light source 3 cannot enter the eyes of the user, and at the same time, the user can observe the dust in the air flow when the air flow passes through the light emitted from the first light source 3.
Referring to fig. 3, in order to further ensure that the user can clearly see the dust in the air flow, the light emitted from the first light source 3 has a sufficient coverage area, in this embodiment, the light emitted from the first light source 3 is emitted in a fan shape, so that when the air flows, a large amount of air passes through the light emitted from the first light source 3, and the user can more easily see the dust in the air flow.
In order to ensure sufficient brightness of the light emitted by the first light source 3 and safety of the first light source 3, in the present embodiment, the light emitted by the first light source 3 is the atom stimulated emission light, the power of the atom stimulated emission light is 0.1mW to 5mW, the wavelength is 300-700nm, and the atom stimulated emission light is emitted by continuous emission or interval with period of 0.1s to 5 s; the light excited by the atoms forms a scattering angle of 15 degrees through the scattering device.
It will be appreciated that the power of the light emitted by the excited atoms determines the brightness of the light, the greater the power, the greater the brightness of the light emitted by the excited atoms, the more easily dust can be observed by the user when the air flows through the light emitted by the first light source 3, and the greater the power consumption of the first light source 3. In practical use, the power of the light emitted by the atoms can be determined according to practical situations, as long as the brightness of the light emitted by the first light source 3 is ensured, so that the dust in the air can be seen clearly by the user through the light channel, and the safety of the first light source 3 is ensured.
In the present embodiment, in order to ensure that dust in the air flow can be clearly seen when the user observes the air flow in the air duct cavity through the viewing channel when the first light source 3 illuminates the wall surface, the power of the light emitted by the atoms is 0.1mW to 5mW, optionally, the power of the light emitted by the atoms is 0.1mW to 1mW, 1mW to 2mW, 2mW to 3mW, 3mW or 3mW to 5mW, when the power of the light emitted by the atoms is 0.1mW to 1mW, 1mW to 2mW and 2mW, the power of the light emitted by the atoms is small, and when the air flows through the light emitted by the first light source 3, the light emitted by the first light source 3 is not only bright enough to enable the user to clearly see the dust in the air, but also low in energy consumption and high safety; when the power of the light emitted by the excited atomic emission is 2mW to 3mW, 3mW or 3mW to 5mW, the power of the light emitted by the excited atomic emission is relatively high, the brightness of the light is relatively high, the dust is more easily observed by a user when the air flows through the light emitted by the first light source 3, the dust in the air can be more easily observed by the user, and the light safety performance with the power less than 5mW is still relatively high.
The light that atom stimulated emission goes out can high frequency emission, also can send emission continuously, its purpose is when light is launched, can let the user observe the condition of the dust in the air current, in this embodiment, when the light that atom stimulated emission goes out adopts continuous emission, the orbit of the light that atom stimulated emission goes out is clear visible, when the user observes the air in the wind channel intracavity through looking at the light passageway, not only can see the dust in the air, still can see the orbit of light, simultaneously by the light of the light that atom stimulated emission goes out is thinner, the scattering angle that light formed through the scattering device is 15 degrees, can make light become thick, not only can make the user observe the emission orbit of light, can also make the user more clear see the dust in the air current.
In other embodiments, the light emitted by the first light source 3 is light emitted by atoms in an interval emission manner of 0.1s to 5s, and the light emitted by atoms is emitted at intervals, so that dust in the air can be emitted for multiple times when passing through the propagation path of the light emitted by the first light source 3 along with the air flow, and the dust seen by a user is relatively clear.
It can be understood that, when the light excited and radiated by the atoms adopts an interval emission mode, as long as the emission frequency of the light is ensured to be high enough, the light track is also visible, and when a user observes the air in the air duct cavity through the visual light channel, the dust condition in the air flow can still be seen, optionally, the emission frequency of the light excited and radiated by the atoms is 0.1s, 0.1s to 0.3s, 0.3s to 3s, 3s and 3s to 5s, and when the emission frequency of the light excited and radiated by the atoms is 0.1s and 0.1s to 0.3s, the emission frequency of the light is higher, and the light track is the same as the light emitted by the atoms in a continuous emission mode, the track is clearly visible, and when the user observes the air in the air duct cavity through the visual light channel, the dust in the air and the light track can also be seen; especially when the interval emission frequency of the light emitted by the atom excited radiation is between 0.3s and 3s, the first light source 3 emits light with high frequency, dust in the air can be reflected for multiple times, and the effect of the dust in the air when a user penetrates through the optical difference of the optical channel is better than the effect that the light emitted by the first light source 3 irradiates the dust by adopting the light emitted by the atom excited continuous emission; when the interval emission frequency of the light emitted by the atoms is 3s and 3s to 5s, the frequency of the light emitted by the first light source 3 can still ensure that the dust in the air can be seen when the user observes the air in the air duct cavity through the optical channel.
In this embodiment, the wall surface irradiated by the excited radiation of the atoms is provided with a diffuse reflection layer, the diffuse reflection layer is composed of high reflection scattering particles, high refraction scattering particles and high heat conduction scattering particles with whiteness of more than 90, the thickness of the diffuse reflection layer is 30-100 μm, the reflectivity of the diffuse reflection layer is more than 90%, the diffuse reflection layer is arranged on the wall surface irradiated by the first light source 3, the high reflection scattering particles, the high refraction scattering particles and the high heat conduction scattering particles which form the diffuse reflection layer increase the roughness of the wall surface, when the light emitted by the first light source 3 is irradiated to the diffuse reflection layer on the wall surface, because the surface of the diffuse reflection layer on the wall surface is rough, the diffuse reflection layer can reflect light rays towards all directions, therefore, after the first light source 3 passes through the diffuse reflection layer, the reflected light is irregularly reflected towards different directions, so that the energy of the light emitted by the excited atoms can be lost, and the light pollution is reduced.
In other embodiments, the wall surface irradiated by the atom stimulated radiation may also be a mirror, the mirror has a deflection angle, when the atom stimulated radiation irradiates the mirror, two beams of light are formed, the light-gathering light column area and the light stroke are increased, so that the dust condition is easier to find when the user observes the air in the air duct cavity through the light viewing channel.
In other embodiments, the light emitted from the first light source 3 is the light condensed by the light-emitting body through the condensing lens, the center of the light-emitting body is located at the focal point of the condensing lens, and the light condensed by the condensing lens is divided into a light pillar region having the condensed light and a region having no condensed light. The user can observe the dust situation in the air duct cavity at the downstream of the air duct 11 through the sight light channel, because the light beam area with the light gathering has a relatively large brightness, the user can observe the dust situation more clearly, when the user observes the dust situation through the sight light channel, if it is observed that the dust in the light beam area with the light gathering is less through the light emitted by the first light source 3, it is better to explain that the purifying module 2 purifies the air, if it is observed that the dust in the light beam area with the light gathering is more through the light emitted by the first light source 3, it is worse to explain that the purifying module 2 purifies the air, the filter screen of the purifying module 2 needs to be replaced, or the dust collecting plate of the purifying module 2 needs to be cleaned. It can be understood that the luminous body can be a luminous body which can emit parallel light beams, such as an LED point light source, and the like, and the condensing lens has stronger condensing capacity, so that the brightness of the light emitted by the luminous body is enhanced after the light emitted by the luminous body is condensed by the condensing lens, and the dust condition can be found more easily when a user observes the air in the air duct cavity through the sight channel.
In this embodiment, the purification module 2 is used to reduce the number of dust particles in the air, the purification module 2 can filter the dust in the air by using a filter screen, an HEPA filter screen (high efficiency air filter screen) is carried inside the purification module 2, the filtering precision of the HEPA filter screen is in micron level, when the purification device with a light source works, the air can pass through the gap of the HEPA filter screen, but tiny particles in the air can be intercepted, and the filtering efficiency of the HEPA filter screen can exceed 99.97% for particles with the diameter below 0.3 micron; but the HEPA filter screen needs periodic replacement, if be in the haze high-speed period or the use frequency is comparatively frequent, the change frequency of HEPA filter screen is also higher. In other embodiments, the purification module 2 can also reduce the number of dust particles in the air by adopting an electrostatic dust removal mode, the electrostatic dust removal mode is to carry charges inside, an electric field is formed between a positive electrode and a negative electrode by the principle that the positive electrode and the negative electrode attract each other, and then some particulate matters are adsorbed inside the purification module 2 by a large amount of electrons and ions in the electric field.
Therefore, no matter which dust removal method is adopted by the air purification device with the first light source 3 in the present embodiment, when the user turns on the air purification device with the first light source 3 in the present embodiment, the user only needs to observe the condition of the air in the air duct 11 when passing through the light emitted by the first light source 3 from the viewing light channel, and the cleaning condition of the air purification module 2 on the dust particles in the air can be determined by looking at the amount of the dust in the air flow, when the user observes the condition of the dust through the viewing light channel, and observes that a large amount of dust floats in the air flow when passing through the light emitted by the first light source 3, which indicates that the air purification effect of the air purification module 2 is poor, and the filter screen of the air purification module 2 needs to be replaced, or the dust collection plate of the air purification module 2 needs to be cleaned.
Purifier is at the in-process of long-term use, because 1 top of casing is located to the air outlet in wind channel 11, under the condition that does not have the covering, not only is the dust stained with easily in 11 air outlet in wind channel when purifier is out of operation state to inside the dust also got into casing 1 through 11 air outlet in wind channel easily, influenced purifier's performance, reduced purifier's life. Referring to fig. 2 again, in the present embodiment, an air valve device 4 is disposed at an air outlet of the air duct 11, the air valve device 4 is used for opening or closing the air outlet of the air duct 11, the air valve device 4 includes a guide vane and a guide vane driving member, the guide vane is made of opaque material and is connected to a driving end of the guide vane driving member, and the guide vane driving member is used for driving the guide vane to rotate so as to open or close the air outlet. When the purification device works, the guide vane driving piece drives the guide vane to rotate, so that the guide vane opens the air outlet of the air channel 11, the air purified by the purification module 2 flows along the air channel 11 and is discharged through the air outlet of the air channel 11, when the purification device with the light source is in an out-of-operation state, the guide vane driving piece drives the guide vane to rotate, so that the guide vane closes the air outlet of the air channel 11, dust in the air cannot be adhered to the air outlet of the air channel 11, and the dust cannot enter the shell 1 through the air outlet of the air channel 11.
In this embodiment, the purification device with the light source has an open state and a close state, when the purification device is in the open state, the guide vane driving member drives the guide vane to rotate and open the air outlet, and the air channel cavity irradiated by the first light source 3 can be observed along the air passage on one side of the guide vane; when the air conditioner is in a closed state, the first light source 3 is closed, and the guide vane driving piece drives the guide vane to rotate and close the air outlet. That is to say, when the purification apparatus with light source of this embodiment starts to work, the first light source 3 can be turned on or off according to the needs of the user, when the user needs to observe the air purification effect of the purification module 2, the user can turn on the first light source 3 in the process of starting up, and then observe the air condition after purification of the purification module 2 through the optical channel, so as to determine the purification effect of the purification module 2, or determine whether the filter screen of the purification module 2 needs to be replaced or whether the dust collecting plate needs to be cleaned, after the purification effect is observed, the user has the option to continue to turn on the first light source 3 or turn off the first light source 3, when the purification apparatus with light source of this embodiment is turned off by the user, the guide vane driving part drives the guide vane to rotate, so that the guide vane closes the air outlet of the air duct 11, and if the first light source 3 is in the on state, when the purification apparatus is turned off, the first light source 3 is also automatically turned off, which may facilitate the operation and may also prevent the user from turning off the first light source 3.
In this embodiment, the viewing channel includes a transparent member disposed on the housing 1, the transparent member faces the irradiation path of the first light source 3, and neither the first light source 3 nor the irradiated reflected light can directly exit from the transparent member. That is, the transparent member is not located on the propagation path of the light emitted from the first light source 3 and is not located on the propagation path of the light after the light emitted from the first light source 3 is diffusely reflected, so that when the user looks through the transparent member into the air duct 11, the dust in the air flow of the light emitted from the first light source 3 can be seen, and since neither the first light source 3 nor the reflected light emitted therefrom can be directly emitted from the transparent member, when the user looks at the air processed by the purification module 2, neither the first light source 3 nor the reflected light emitted therefrom can be emitted to the human eyes, and the user can be prevented from being hurt by the eyes when he looks at the air processed by the purification module 2.
In other embodiments, the viewing channel comprises a through hole provided in the housing 1, facing the illumination path of the first light source 3, and the first light source 3 and the reflected light irradiated by the first light source cannot directly emit from the through hole, that is, the through hole is not located on the propagation path of the light emitted by the first light source 3, nor on the propagation path of the light after the light emitted by the first light source 3 is diffused, so that when the user looks into the air duct 11 through the through hole, the dust in the air flow of the light emitted by the first light source 3 can be seen, and since the first light source 3 and the reflected light emitted therefrom cannot be directly emitted from the through hole, therefore, when the user observes the condition of the air treated by the purification module 2, the first light source 3 and the reflected light irradiated by the first light source cannot be emitted into human eyes, so that the eyes of the user can be prevented from being punctured when the user observes the condition of the air treated by the purification module 2.
That is, whether the transparent member is disposed in the direction of the housing 1 facing the irradiation path of the first light source 3 or the through hole is disposed in the direction of the housing 1 facing the irradiation path of the first light source 3, the purpose of the viewing path is to facilitate the user to observe the dust condition in the air when the first light source 3 irradiates the air duct cavity, and the eyes of the user are not pricked by the first light source 3 and the reflected light irradiated by the first light source 3 during the observation process.
