Detailed Description
The technical solution of the present invention is further described in detail with reference to the drawings and the specific embodiments of the specification.
As shown in fig. 1, the present embodiment provides an air purifier, including:
an outer case 110 having an air inlet 111 and an air outlet 112;
an inner box 120 located inside the outer box 110, and separating a hollow space enclosed by the outer box 110 into a first box and a second box, wherein the second box is located inside the first box;
a screen comprising at least:
the first type filter screen 131 is positioned in the first box body and is used for carrying out first type purification on the gas;
the second type of filter screen 132 is positioned in the second box body and is used for carrying out second type of purification on air;
the wind wheel 140 is used for driving air to enter from the air inlet 111 and to be discharged from the air outlet 112;
a controlled switch 150 for controlling the first type of filter screen 131 and the second type of filter screen 132 to purify air separately or jointly
The wind wheel 140 is used for driving air to enter from the air inlet 111 and to be discharged from the air outlet 112;
a controlled switch 150 for controlling the first type of filter screen 131 and the second type of filter screen 132 to purify air individually or in combination.
The first type of screen 131 and the second type of screen 132 are different types of screens. For example, the first type screen 131 may be a screen for purifying air by using physical interception, for example, a screen for intercepting haze particles in air by using interception holes on the screen. The second type of filter 132 may be a filter for intercepting some toxic or harmful substances in the air by using a chemical reaction, for example, a filter for filtering formaldehyde or sulfide in the air by using a chemical reaction.
Therefore, if the first type of filter 131 is a physical interception type filter, the second type of filter 132 may be a chemical reaction type filter; alternatively, if the first type of filter screen 131 is a chemical reaction type filter screen, the second type of filter screen 132 is a physical interception type filter screen.
In some embodiments, the screen may include a third type of screen in addition to the first type of screen 131 and the second type of screen 132.
The inner case 120 may include a plurality of cases, and different types of filter screens may be disposed in the different cases, respectively.
In some embodiments, the inner box 120 may be divided into N inner boxes 120, for example, the (N + 1) th inner box 120 is nested in the nth inner box 120 to form a nested multi-layer inner box 120. Therefore, the working state of each type of filter screen can be controlled independently, and various filter screens can be filtered sequentially by the air through the nested inner box bodies 120 when various filter screens work. The arrows in fig. 1 indicate the direction of air flow.
In some implementations, the filter screens used with the lowest frequency may be located in the nth layer of casing 120 and the filter screen used with the highest frequency may be located between the outer casing 110 and the 1 st layer of casing 120, depending on the frequency of use of the various types of filter screens.
In some embodiments, the first type of filter screen 131 and the second type of filter screen 132 may be further divided according to intercepted substances, for example, the first type of filter screen 131 and the second type of filter screen 132 may both be chemically reacted filter screens, the first type of filter screen 131 may be a filter screen intercepting the substance a, and the second type of filter screen 132 may be a filter screen intercepting the substance B.
In summary, in the present embodiment, the first type of filter screen 131 and the second type of filter screen 132 are different types of filter screens, and perform different evolutions on air respectively.
It should be noted that, in the embodiment of the present invention, in order to separately control the operations of different types of filter screens,
the first type of strainer 131 and the second type of strainer 132 are separately provided. In this way, whether the first type of filter screen 131 and/or the second type of filter screen 132 are in the cleaning state can be controlled by opening and closing the different boxes.
The controlled switch 150 may be various types of electronic switches and/or electromagnetic switches, and controls the wind field in the first and second cases, and whether the first and second filters 131 and 132 perform air purification may be controlled by controlling the wind field. Therefore, the air purification device can avoid that when air is not required to be purified, the air still needs to pass through the corresponding filter screen, so that the consumption of the filter screen is caused, and meanwhile, the power consumption caused by the filter screen which does not need to pass through is reduced.
Therefore, the purifier provided by the embodiment can respectively control the filter screens of different types to perform air purification through the isolation of the filter screens of different types, reduce unnecessary consumption of the filter screens, reduce the phenomenon of electric energy consumption caused by large wind resistance, and further has the characteristics of small filter screen consumption and small electric energy consumption.
When various filter screens in air purifier carry out air purification alone, then the air that comes out from air purifier this moment only carries out the purification of corresponding type, if when air purifier's various filter screens jointly carried out air purification, then the air that comes out from air purifier this moment has passed through two kinds of purifications at least simultaneously, for example, has passed through the purification of all types of filter screens in the air purifier.
In addition, in this embodiment, by adding the inner box 120 and the controlled switch 150 to the outer box 110, whether air purification is performed on different filter screens can be easily controlled, so that the opening control of different purification functions of the air purifier can be realized, the number of added devices is small, and the size of the air purifier does not need to be increased.
Optionally, the second box is provided with a channel for air in and out of the first box.
The second box body is an isolated hollow inside of the first box body, and channels for air in the first cavity to enter and discharge are arranged on the second box body, and the channels can be air inlet holes and air outlet holes on the inner box body 120, and can also be various openings on the inner box body 120, and are not limited to air holes.
In some embodiments, as shown in fig. 2, the rotor 140 includes:
the first wind wheel 141 is positioned between the first type of filter screen 131 and the air outlet 112, and is used for driving air to enter from the air inlet 111 and to be discharged from the air outlet 112 after passing through the first type of filter screen 131;
and/or the presence of a gas in the gas,
and the second wind wheel 142 is positioned in the second box body, is positioned in the second type of filter screen 132 and enters the air inlet 111, and is discharged from the air outlet 112 after passing through the second type of filter screen 132.
In this embodiment, the different filter screens that the separation set up corresponding wind wheel 140 respectively, and wind wheel 140 here can rotate through self whether to realize producing the drive power whether the air passes through the filter screen that corresponds, thereby makes the filter screen that corresponds whether carry out the control that purifies to the air, thereby to some circumstances, can reduce the filter screen that the air passes through to correspond, thereby reduces the consumption of these filter screens and reduces the consumption.

In this embodiment, the first controlled switch and the second controlled switch may be various electronic components that are controlled to be turned on or off according to the control signal, such as a single transistor and/or a transistor, or a switching circuit including a transistor and/or a transistor.
The first controlled switch can control whether the air in the outer box 110 passes through the first type of filter screen 131 by controlling the working state of the first wind wheel 141. For example, the first controlled switch may be disposed on a power supply circuit of the first wind wheel 141, and the first controlled switch may control the on or off of the first controlled switch to supply power to the first wind wheel 141. When the first wind wheel 141 is powered on, the first wind wheel will enter a working state, so that negative pressure is formed on one side close to the air outlet 112, and air is driven to transfer from one side close to the air inlet 111 to one side close to the air outlet 112, and then the air inevitably passes through the corresponding filter screens positioned on the paths of the air inlet 111 and the air outlet 112, so that the physical structure of the filter screens and/or chemical substances arranged in the modes of coating on the filter screens and the like react, and the physical and/or chemical purification of the air is realized.

In this embodiment, different types of filter screens may share one wind wheel 140, the maximum power of the wind wheel 140 may be greater than a predetermined power, and power consumption required for simultaneously performing air purification on a plurality of filter screens may be provided.
In other embodiments, the operating state of the rotor 140 may include multiple gears. When the wind wheel 140 works at different gears, the rotation speeds of the wind wheel 140 are different, the negative pressure formed at the position close to the air outlet 112 is different, and the power consumption of the corresponding wind wheel 140 is also different.
In this embodiment, the air purifier further includes:
and the controller is connected with the wind wheel 140 and used for determining the working gear of the wind wheel 140 according to the number and/or the type of the current filter screens for air purification and controlling the working signal of the wind wheel 140, which is in the corresponding working gear.
In this embodiment, the controlled switch 150 is a switch connected to the isolation device.
In this embodiment, the isolating means may be various valves which control the connection and disconnection of the passage connecting the first tank and the second tank, and when the passage is connected, air may enter the second tank from the first tank. The isolation device may be an electronic valve and/or a solenoid valve.
In some embodiments, the isolation device may be an isolation door; the controlled switch 150 may be the driving device connected to the isolation door, and the isolation door may block the passage or may conduct the passage by changing a position of the driving isolation door.
In summary, in this embodiment, the isolation device has many kinds, and the above are only some optional devices, and when the isolation device is implemented, the isolation device is not limited to any one of the above.
In the above embodiment, the controlled switch 150 is used to control the wind wheel 140, and in the present embodiment, since the wind wheel 140 is shared by various types of screens, the controlled switch 150 is used to control the isolation device, so that the control of the passage of air inside the outer case 110 is possible.
Optionally, the air outlet 112 includes:
the first type of air outlet is communicated with the first box body;
and the second type air outlet is communicated with the second box body.
