The invention belongs to the field of air purifier, in particular to an air purifier with independent dual channel.
With the rapid development of industry leading to diversified air pollution emissions accompanying climate change caused by a large number of particulate matters harmful to the living environment, has become one of the main indicators for assessing the degree of air pollution. Particulate matters can stay in the atmosphere for a long time, and can enter the body with respiration, accumulate in the trachea or lungs, which is very harmful to human health. Fog, dust, pollen, dandruff and smog, etc. in daily life can be the particulate matters that may cause human discomfort.
Nowadays, the common way to eliminate indoor particulate matter is to place air purifiers indoors and to purify the air through internal circulation. In the process of purifying the air, the existing air purifier adopts the suction fan and the intake filter mesh to suck the air into the air purifier for preliminary filtration, and then uses the photocatalyst and ultraviolet light set in the air purifier to achieve the purpose of disinfection and sterilization. However, in order to filter fine particulate matters in the air, it is necessary to use the intake filter mesh with finer porosity, so the suction force of the suction fan must be increased to overcome the high resistance of the finer mesh and suck proper amount of air smoothly into the channel of the air purifier for further disinfection and sterilization, for example, using photocatalyst and ultraviolet light. In the above process of the existing air purifier, because the air flow introduced into a single channel has the same speed, it is impossible to simultaneously take into account both the need for high-speed air flow provided by the high-suction fan for overcoming the filtration process of the high flow resistance filter mesh, and the need for low-speed air flow provided by the low-suction fan for carrying out the purification process requiring longer residence time. Therefore, these two purification processes on the existing air purifier lead to the problem of either unable to cope with one without letting go of the other, or the processing effects of both are not complete.
It can be seen that there are still many shortcomings in the conventional air purifier. In order to take into account the two functions of air filtration and air purification to promote the overall efficiency of the air purifier, the conventional air purifier needs to be improved urgently.
The invention provides an air purifier with independent dual channel, which mainly comprises a first channel portion and a second channel portion. The first channel portion filters particulate matters in the air and the second channel portion purifies the air. The first channel portion includes a filtration channel, a suction fan and a filter mesh. The suction fan is arranged between the suction end and the exhaust end in the filtration channel to provide suction for passing the outside air through the filter mesh arranged near the suction fan towards the suction end side of the filtration channel, and then the air of the filtered particulate matters is sucked into the filtration channel and sent out to the exhaust end. The second channel portion includes a purification channel, an intake fan and an air purification module. The intake fan is arranged between an inlet end and an outlet end in the purification channel to provide suction for sucking air into the purification channel, and the purified air is sent out from the outlet end by the air purification module arranged in the inlet end.
The bore of the filtration channel gradually expands from the suction end to the exhaust end. The first channel portion further includes a particulate matter detection module adjacent to the exhaust end.
The bore of the purification channel gradually expands from the inlet end to the outlet end, and the air purification module is one or combination of an ozone generator, a photocatalyst sterilizer and an anion generator.
The suction fan is a swirl-flow fan, which provides greater suction for the outside air to overcome the resistance of the filter mesh and enter the filtration channel to achieve filtering effect. The intake fan is an axial-flow fan, which provides less suction to prolong the residence time of the air in the purification channel to achieve the effect of fully purifying the air.
Air purifier with independent dual channel of the invention further comprises a shell portion which accommodates the first channel portion and the second channel portion therein, and the shell portion comprises a front cover, a rear cover, a left cover, a right cover, an upper cover and a lower cover; wherein the front cover is connected with one end of the purification channel, and an inlet port is arranged on the front cover corresponding to the inlet end of the purification channel; wherein the rear cover is connected with the other end of the purification channel, and an outlet port is arranged on the rear cover corresponding to the outlet end of the purification channel; wherein the left cover is arranged on one side of both the filtration channel and the purification channel; wherein the right cover is arranged on the other side of both the filtration channel and the purification channel, and a suction port is arranged on the right cover corresponding to the suction end of the filtration channel; wherein the upper cover is connected with one end of the filtration channel, and an exhaust port is arranged on the upper cover corresponding to at the exhaust end of the filtration channel; and wherein the lower cover is arranged at the bottom of the purification channel. The right cover further includes a filter mesh fixture, and the filter mesh is clamped between the filter mesh fixture and the suction port of the right cover.

The present invention is based on the fact that the existing air purifier is to complete two processes of air filtration and air purification by air passing through a single channel. However, in practice, the same air velocity in the single channel cannot simultaneously meet the processing requirements of the above two different functions, thereby leading to the problem of either unable to cope with one without letting go of the other, or the processing effects of both are not complete. In order to solve the aforesaid problems of the existing technology, an air purifier with independent dual channel is proposed, which not only separates the channels for processing air filtration and air purification, but also more matches the selection of suction fan and intake fan according to their specific air flow speed requirements, so as to deal with the filtration and purification processes independently. Thus, the overall performance of the air purifier with independent dual channel of the invention can be significantly improved through optimal air filtration and air purification effects.
