[0046] Fourthly, the internal circulation purification mode.

[0047] In this working mode, the first air port 21 is opened, and the second air exchange assembly 6 is closed.

[0048] In this embodiment, the second air exchange assembly 6 is provided with an air door, which is used for controlling the opening or closing of any port of the second air exchange assembly 6. The air door can be a valve body, a cover body or a capsule body.

[0049] Specifically, the first air port 21 is opened, the second air exchange assembly 6 is closed, the indoor environment input from the first air port 21 is output from the second air port 22, the air output from the second air port 22 is discharged from the purification liquid after being filtered and purified in the purification liquid, enters the indoor environment through the first communication port, and the purification of the indoor environment is realized.

[0050] Wherein, the second end of the second air exchange assembly 6 is communicated with the first purification chamber 1, and the air purification device at least includes the following three working modes.

[0051] One is a green exhaust air purification mode.

[0052] In this working mode, the first communication port is closed, the second air exchange assembly 6 is opened, and the air exchange direction of the second air exchange assembly 6 is from the indoor environment to the outdoor environment.

[0055] It can be understood that due to factors such as decoration, the indoor environment contains harmful substances such as formaldehyde, and directly discharging the harmful substances to the outdoor environment will cause environmental pollution. The present scheme preliminarily filters the control of discharging to the outdoor environment, can remove harmful substances in the air, and discharges clean gas to the outdoor environment, which is green and environmentally friendly.

[0062] The air purification device provided by the application has the functions of exhaust air purification mode, first fresh air purification mode, fresh air deep purification mode, internal circulation purification mode, green exhaust air purification mode, second fresh air purification mode and the like.

[0063] The first purification chamber 1 is provided with the purification liquid, which can be an air purification liquid known in the art.

[0064] It should be noted that the type of the purification liquid in the first purification chamber 1 can be selected according to the harmful substances in the air to be purified, for example, the type of the purification liquid includes water, potassium permanganate, plant extract and the like.

[0065] For example, if dust, sand and other particulate matters in the air need to be removed, water can be selected as the purification liquid, which can effectively remove the particulate matters in the air when the air passes through the purification liquid, so as to achieve the purification effect, and at the same time, the humidity in the air can be increased, which is economic and environmentally friendly.

[0066] Alternatively, if formaldehyde in the air needs to be removed, a purification liquid that can dissolve formaldehyde can be selected, so that the formaldehyde in the air is decomposed or dissolved when the air passes through the purification liquid, thereby achieving the purpose of removing formaldehyde.

[0067] The first air port 21 can be used to communicate with the indoor environment, or can be communicated with the outdoor environment through the second air exchange assembly 6. The air to be purified in the indoor environment enters the first air exchange assembly 2 through the first air port 21; the second air port 22 is located below the liquid level of the purification liquid, so that the air discharged from the second air port 22 is discharged from the purification liquid, so that the harmful substances or particulate matters in the air are removed by the purification liquid.

[0068] In some embodiments, the second air port 22 extends into the purification liquid and extends to the bottom of the first purification chamber 1, so as to increase the residence time and moving path of the air to be purified in the purification liquid, and enhance the purification effect of the purification liquid on the air to be purified.

[0069] In some embodiments, the opening direction of the second air port 22 in the purification liquid can be set in multiple directions, for example, the opening direction of the second air port 22 can be towards the bottom of the first purification chamber 1, or the opening direction of the second air port 22 can be towards the side wall of the first purification chamber 1.

[0070] In some embodiments, the second air exchange assembly 6 comprises an air exchange chamber and a fan; the air exchange chamber is provided with a first port and a second port, the first port is used for communication with the outdoor environment, and the second port is in communication with the first air exchange assembly 2 or the first purification chamber 1.

[0071] The fan in the air exchange chamber is used to suck fresh air or drive air to flow out of the second end of the second air exchange assembly 6, which accelerates air flow and improves the use efficiency of the air purification device.

[0072] In some embodiments, the second air exchange assembly 6 is provided with a third port for communication with the indoor environment, and one of the first port and the third port of the second air exchange assembly 6 is located on the air inlet side of the fan, and the other is located on the air outlet side of the fan.

[0073] In this embodiment, when the air flow direction in the heat exchanger is from indoor to outdoor, the fan is turned on, the damper in the heat exchanger controls the port on the air inlet side of the fan to be closed and the port on the air inlet side of the fan to be opened, which accelerates the speed of air flowing from indoor to outdoor and speeds up the air exchange efficiency.

[0074] Or, when the air flow direction in the heat exchanger is from outdoor to indoor, the fan is turned on, the damper in the heat exchanger controls the port on the air inlet side of the fan to be opened and the port on the air inlet side of the fan to be closed, which accelerates the speed of air flowing from outdoor to indoor and speeds up the air exchange efficiency.

[0075] Further, the first air exchange assembly 2 comprises a gas conveying pipe 23 and a first fan; one end of the gas conveying pipe 23 is provided with a first air port 21, the other end of the gas conveying pipe 23 is provided with a second air port 22, the gas conveying pipe 23 passes through the first purification chamber 1 and extends below the liquid level of the purification liquid, the first air port 21 is located on the air inlet side of the fan, and the first fan is used to drive air to flow from the first air port 21 to the second air port 22; the first communication port is higher than the liquid level of the purification liquid.

[0076] It can be understood that the gas conveying pipe 23 communicates the first air port 21 and the second air port 22, and can transport the air to be purified into the purification liquid, so that the air to be purified flows through the purification liquid, thereby removing harmful substances or particulate matters in the air to be purified.

[0077] In some embodiments, the pipe part of the gas conveying pipe 23 close to the first air port 21 and located on the liquid level of the purification liquid is connected with the second air exchange assembly through a pipeline or other conventional gas conveying equipment.

[0078] In some embodiments, the air supply pipe 23 extends into the purification liquid and extends to the bottom of the first purification chamber 1 to increase the residence time and movement path of the air to be purified in the purification liquid, thereby enhancing the purification effect of the purification liquid on the air to be purified.

[0079] The first fan is installed in the air duct formed by the first air inlet 21 and the second air inlet 22 to create a negative pressure in the air supply pipe 23, draw in the air to be purified, and drive the air to flow from the first air inlet 21 to the second air inlet 22.

[0080] In some embodiments, the first air inlet 21 is located on the air inlet side of the first fan, and the second air inlet 22 is located on the air outlet side of the first fan, which can improve the efficiency of the first fan in driving the air.

[0081] Understandably, the first connection port is higher than the liquid level of the purification liquid. This prevents the purification liquid from flowing out of the connection port and causing leakage, while allowing air to flow out of the connection port without obstruction.

[0082] like Figure 3 As shown, in some embodiments, a filter assembly 11 is also provided in the first cleanroom 1. The filter assembly 11 is installed in at least two of the following locations within the first cleanroom 1.

[0083] Firstly, the filter assembly 11 is located above the surface of the purification liquid. The filter assembly 11 divides the first purification chamber 1 into a first chamber and a second chamber, which are distributed at the top and bottom respectively. The purification liquid is placed in the second chamber, and the first connecting port is connected to the first chamber.

[0084] In this configuration, the air output from the second air outlet 22 is first discharged from the purification liquid after being introduced into the purification liquid, and then enters the first room after being filtered by the filter assembly 11.

[0085] Understandably, the filter assembly 11 in the first purification chamber 1 provides another layer of filtration for the air, further improving the air purification device's filtration effect.

[0086] The filter component 11 can be an air purification device known in the art, such as a filter screen or a porous adsorption layer.

[0087] It should be noted that the type of filter component 11 in the first purification chamber 1 can be selected according to the type of harmful substances in the air to be purified.

[0088] Secondly, the filter assembly 11 is immersed in the purification liquid, and the filter assembly 11 divides the purification liquid into a first chamber and a second chamber distributed at the top and bottom.

[0089] In this arrangement, the air outputted by the second air port 22 is firstly subjected to the filtering treatment of the filtering assembly 11 after being introduced into the purification liquid, and then is discharged from the purification liquid into the first chamber.

[0090] Specifically, the filtering assembly 11 divides the purification liquid into the first chamber and the second chamber distributed in the upper and lower positions, the air outputted by the second air port 22 is subjected to the preliminary filtering by the purification liquid in the first chamber after being introduced into the purification liquid in the first chamber, the particulate matters and harmful substances in the air are preliminarily removed, the preliminarily purified air is then introduced into the purification liquid in the second chamber through the filtering assembly 11, the filtering assembly 11 can remove the particulate matters and harmful substances in the air for the second time, and the purification liquid in the second chamber can remove the particulate matters and harmful substances in the air for the third time.

[0091] It can be understood that the particulate matters and harmful substances in the purification liquid in the first chamber cannot reach the purification liquid in the second chamber after being filtered by the filtering assembly 11, so the particulate matters and harmful substances in the purification liquid in the second chamber are much less than those in the purification liquid in the first chamber. When the purification capacity of the purification liquid in the first chamber reaches the limit, the purification liquid in the second chamber can continue to purify, the purification capacity of the purification liquid is maximized, and the service life of the purification liquid is prolonged. The arrangement of dividing the purification liquid into two layers plays a double purification role compared with the arrangement of only one layer of purification liquid, increases the purification capacity of the purification liquid, and further increases the purification effect of the air purification device.

[0092] Among them, the filtering assembly 11 can not only play a blocking and filtering role on the particulate matters and harmful substances in the purification liquid in the first chamber, but also can play a further filtering role on the air when the air passes through the filtering assembly 11 and enters the first chamber, thereby further improving the filtering effect.

[0093] In some embodiments, the filtering assembly 11 can be arranged in multiple groups, and the multiple groups of filtering assemblies 11 are arranged along the height direction of the first purification chamber 1, which can further improve the purification capacity of the air.

[0094] Among them, the multiple groups of filtering assemblies 11 can filter the same harmful substances by using the same filtering material, or can filter different harmful substances by using different filtering materials.

[0095] In some embodiments, as shown in Figure 3 , the multiple groups of filtering assemblies 11 are detachably connected with the air conveying pipe 23. The detachable connection mode can be sleeving or threaded connection, and the embodiment does not limit the connection mode. The detachable connection mode facilitates the replacement of the filtering assembly 11.

[0096] Further, as shown in Figure 2 and Figure 3As shown, the air purification device further comprises a heating chamber 4, one end of the heating chamber 4 is communicated with the first communication port, and the other end is used for being communicated with the indoor environment.

[0097] Specifically, after the first communication port is opened, the first purification chamber 1 and the heating chamber 4 are communicated, the air purified by the purification liquid and the filtering assembly 11 in the first purification chamber 1 is heated and disinfected by the heating chamber 4, and then enters the indoor environment, so as to achieve the multiple purification effect.

[0098] It should be noted that the heating temperature of the heating chamber 4 can reach 55-70℃, for example, 60℃, and it is verified by experiments that when the air temperature is heated to the range of 55-70℃, the obvious sterilization effect can be achieved.

[0099] It can be understood that one end of the heating chamber 4 is communicated with the first communication port, and the first communication port is higher than the liquid level of the purification liquid, so that the purification liquid can be prevented from flowing into the heating chamber 4 from the communication port, causing damage to the heating assembly 41, and at the same time, the air can flow into the heating chamber 4 from the communication port without obstruction.

[0100] The heating assembly 41 can be a heating element known in the art, such as a heating wire or a ceramic heater.

[0101] In some embodiments, as shown in Figure 2 and Figure 3 As shown, the air purification device further comprises a second purification chamber 3, the second purification chamber 3 is provided with a third air port 31, and the second purification chamber 3 comprises a filtering interval chamber 33, one end of the filtering interval chamber 33 is communicated with the heating chamber 4, and the other end is communicated with the third air port; the filtering interval chamber 33 is provided with a filtering device 34, and the filtering device 34 is used for purifying the air entering the second purification chamber 3.

[0102] The filtering device 34 of the second purification chamber 3 comprises a filter core, which can be an air purification material known in the art.

[0103] It should be noted that the type of the filter core in the second purification chamber 3 can be selected according to the harmful substances in the air to be purified, for example, the type of the filter core can be selected from an adsorption filter core, a catalytic oxidation filter core, etc.

[0104] For example, in order to remove formaldehyde in the air, an adsorption filter core composed of one or more of volcanic rock, activated carbon, molecular sieve, etc. can be used, which is cheap, fast, and can remove various inorganic and organic pollutants.

[0105] The type of the harmful substances in the air to be purified removed by the filtering assembly 11 can be the same as or different from that of the filtering device 34.

[0106] In the case that the harmful substances in the air to be purified removed by the filtering assembly 11 are of the same type as the filtering device 34, the filtering assembly 11 can preliminarily filter the harmful substances, and the filtering device 34 can secondarily filter the harmful substances, so as to achieve the effect of completely removing the harmful substances in the air.

[0107] In the case that the harmful substances in the air to be purified removed by the filtering assembly 11 are of different types from the filtering device 34, the filtering assembly 11 and the filtering device 34 can cooperate to remove different types of harmful substances in the air, so as to achieve the effect of comprehensively purifying the air.

[0108] The third air port 31 is used for communicating with the indoor space, and the clean air purified by the first purification chamber 1, the heating chamber 4 and the second purification chamber 3 is discharged into the indoor space through the third air port 31.

[0109] The first purification chamber 1 and the second purification chamber 3 are communicated through the heating chamber 4, and the air purified by the first purification chamber 1 is heated and disinfected by the heating chamber 4 and then enters the second purification chamber 3, so as to achieve the effect of multi-stage purification.

[0110] Further, as shown in Figure 2 and Figure 3 The second purification chamber 3 includes a first air storage chamber 32, one end of the first air storage chamber 32 is communicated with the heating chamber 4, and the other end is communicated with the other end of a filtering chamber 33.

[0111] The first air storage chamber 32 can be used for storing the air heated by the heating chamber 4, and the heated air gradually accumulates in the first air storage chamber 32, until the air pressure is greater than a certain value, the air pressure drives the heated air to pass through the filtering device 34, which can avoid the phenomenon that the local filtering device 34 filters the air, causing the local failure of the filter element and the replacement of the filter element. In other words, the air uniformly passes through the filter element in the filtering device 34, which can prolong the service life of the filter element and reduce the cost.

[0112] In some embodiments, the area of the communication port through which the first air storage chamber 32 and the filtering chamber 33 are communicated is not less than the area of the filter element in the filtering device 34, so that the air can more uniformly contact one end of the filter element and uniformly pass through the filter element when the pressure reaches a certain value, further prolonging the service life of the filter element and reducing the cost.

[0113] In some embodiments, the opening area of the first end of the filtering chamber 33 is greater than the opening area of the second end of the filtering chamber 33.

[0114] It can be understood that the opening area of the air inlet into the filtering chamber 33 is larger than the opening area of the air outlet from the filtering chamber 33, which can prolong the residence time of the air in the filtering chamber 33, enhance the purification degree of the filter element to the air, and change the flow path of the air in the filtering chamber 33, so that the air moves transversely when being discharged from the second end of the filtering chamber 33, and the air is purified again by the part of the filter element away from the first end of the filtering chamber 33, so as to maximize the purification capacity of the filter element and avoid waste of the filter element due to different use degrees of different parts of the filter element

[0115] Further, as shown in Figure 2 and Figure 3 The second purification chamber 3 further comprises a second air storage chamber 35, one end of the second air storage chamber 35 is in communication with the other end of the filtering chamber 33, and the other end of the second air storage chamber 35 is in communication with the third air port 31.

[0116] The second air storage chamber 35 can be used to store the air output by the filtering chamber 33.

[0117] It should be noted that since the heating chamber 4 heats the air, the heated air still has a certain amount of heat after passing through the filtering device 34, and the air stored in the second air storage chamber 35 can keep the filter element warm, prevent the temperature of the two ends of the filter element from being uneven, and thus improve the purification effect of the filter element on the air. At the same time, since the residence time of the air in the air purification device is increased, the overheated air can be prevented from being directly discharged into the room, thereby affecting the room temperature and improving the use experience of the air purification device.

[0118] In some embodiments, a second fan is arranged in the second air storage chamber 35, and the second fan is used to drive the air to flow from the second air storage chamber 35 to the third air port 31.

[0119] The arrangement position of the second fan in the second purification chamber 3 at least includes the following two kinds.

[0120] First, a second fan is arranged in the first air storage chamber 32, and the second fan is used to drive the air to enter the filtering chamber 33 from the first air storage chamber 32, thereby improving the flow speed of the air and the purification rate of the air purification device.

[0121] Specifically, the air outlet side of the second fan faces the filtering chamber 33, so as to accelerate the flow speed of the air.

[0122] Second, a second fan is arranged in the second air storage chamber 35, and the second fan is used to drive the air to flow from the second air storage chamber 35 to the third air port 31.

[0123] Specifically, the air outlet side of the second fan faces the filter chamber 33, and the air outlet side of the second fan faces the third air inlet 31, further accelerating the air flow speed and improving the purification rate of the air purification device.

[0124] In some embodiments, the air purification device further includes a housing 5; a first purification chamber 1, a second purification chamber 3, a heating chamber 4, a second ventilation assembly 6, and at least a portion of the first ventilation assembly 2 are detachably disposed within the housing 5; the housing 5 has a first opening 51, a second opening 52, and a third opening 53 on its shell wall, the first opening 51 communicating with a first air inlet 21, the second opening 52 communicating with a third air inlet 31, and the third opening 53 communicating with a first end of the second ventilation assembly 6.

[0125] The first purification chamber 1, the second purification chamber 3, the heating chamber 4, the second ventilation component 6, and at least part of the first ventilation component 2 are disposed inside the outer casing 5, which increases the integration of the air purification device, making the air purification device easy to carry and increasing the application scenarios of the air purification device.

[0126] The first purification chamber 1, the second purification chamber 3, the heating chamber 4, and at least part of the first ventilation assembly 2 are all detachable from the housing, which facilitates the inspection and replacement of the internal parts of the air purification device. For example, when it is necessary to replace the purification liquid in the first purification chamber 1, the first purification chamber 1 can be removed from the housing to replace the purification liquid. Or when it is necessary to replace the filter element of the filter device 34 in the second purification chamber 3, the second purification chamber 3 can be removed from the housing to replace the filter element.

[0127] The detachable connection can be a plug-in connection or a snap-fit ​​connection, and this embodiment does not limit the connection method.

[0128] For example, such as Figure 2 As shown, the outer wall of the first purification chamber 1 is provided with a groove, and the shell is provided with a protrusion structure that matches the groove. The first purification chamber 1 can be plugged and unplugged into the groove and the protrusion structure on the shell.

[0129] For example, such as Figure 3 As shown, the first gas storage chamber 32 is provided with a support column on the side facing the filter chamber 33, and the filter chamber 33 is provided with a through hole on the side facing the first gas storage chamber 32. The position and size of the through hole are adapted to the support column so that the first gas storage chamber 32 can be plugged and unplugged into the through hole of the first gas storage chamber 32 through the support column.

[0130] Among them, such as Figure 1 As shown, the first air inlet 21 of the first ventilation component 2 can protrude from the shell wall of the housing and communicate with the first opening 51, or the first opening 51 can protrude from the shell wall of the housing on the side facing the first purification chamber 1 and communicate with the first air inlet 21 of the first ventilation component 2.

[0131] In some embodiments, a filter screen can be arranged on the first opening 51, which can allow large particles in the air to enter the first purification chamber 1, thereby playing a preliminary filtering role.

[0132] In some embodiments, as shown in Figure 1 The shell wall of the shell is provided with heat dissipation holes for dissipating heat from the internal space of the shell.

[0133] The air purification device provided by the present application has the following advantages.

In the third aspect, after the air is heated by the heating chamber 4, the number of collisions of gas molecules increases, harmful substances are decomposed, and when the gas molecules pass through the filter device 34, the harmful substances in the air can be further filtered, so that the air is thoroughly purified. In the fourth aspect, the moving speed of the gas molecules is accelerated by heating, the speed of the gas molecules passing through the filter device 34 is accelerated, and the driving force of the first fan and the second fan is combined, which can effectively improve the purification rate.
