[0003] Specifically, during the air intake process, a filter element, such as a filter screen, is arranged at the air inlet to filter the incoming gas. However, due to the limited filtration area of the filter screen, in order to ensure the filtration effect of the filter screen on the gas, the user needs to frequently clean or replace the filter screen, which easily increases the labor cost and affects the normal use of the air conditioner.

[0023] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without making creative efforts shall fall within the protection scope of the present application.
[0024] The gas filtering device disclosed in the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.
[0025] Please refer to Figures 1-7 , the present application discloses a gas filtering device, and the disclosed gas filtering device 100 includes a housing 110, a filtering member 120 and a driving mechanism 130.
[0026] The gas filtering device 100 disclosed in the present application is used to filter the gas entering the air conditioner so that there are fewer impurities such as dust in the gas discharged from the air conditioner. The housing 110 is the peripheral structure of the gas filtering device 100. An air flow channel 111 is formed in the housing 110. Gas can move in the air flow channel 111, and the housing 110 is also provided with a first air inlet 112 and a first air outlet 113 communicated with the air flow channel 111. The first air inlet 112 is used to communicate with the second air inlet 210 of the air conditioner, and the first air outlet 113 is used to communicate with the second air outlet 220 of the air conditioner. That is, the gas entering through the second air inlet 210 can enter the air flow channel 111 through the first air inlet 112. The gas moves in the air flow channel 111 to the first air outlet 113 and is finally discharged to the outside of the air conditioner through the first air outlet 113 and the second air outlet 220 in sequence.
[0027] The filtering member 120 can filter impurities such as dust in the gas. Optionally, the filtering member 120 can be a component with a filtering function such as a filter screen or a filter cloth. The filtering member 120 is movably disposed in the air flow channel 111, that is, the filtering member 120 can move relative to the air flow channel 111. The driving mechanism 130 is disposed in the air conditioner, and the driving mechanism 130 is connected to the filtering member 120 to drive the filtering member 120 to move relative to the air flow channel 111 so that different filtering areas of the filtering member 120 are located in the air flow channel 111, and thus different filtering areas of the filtering member 120 can filter the gas in the air flow channel 111.
[0028] Specifically, when the first part of the filter element 120 is located within the air flow channel 111, the corresponding filter area of this first part can filter the gas within the air flow channel 111. After a period of filtration, a relatively large amount of dust and other impurities adhere to this first part. To ensure the gas filtration effect of the filter element 120, the driving mechanism 130 can drive the filter element 120 to move relative to the air flow channel 111, so that the second part of the filter element 120 connected to the first part enters the air flow channel 111. At this time, the corresponding filter area of this second part can filter the gas within the air flow channel 111, and so on, which can ensure the gas filtration effect of the gas filtration device 100.
[0029] In this application, since the filter element 120 is connected to the driving mechanism 130, the driving mechanism 130 can drive the filter element 120 to move relative to the air flow channel 111, so that different filter areas of the filter element 120 can be located within the air flow channel 111, thereby achieving the effect of filtering gas using different filter areas of the filter element 120. While ensuring the intake air filtration effect, it is not necessary to frequently replace or clean the filter element 120, which makes the intake air dust removal of the gas filtration device 100 more convenient and operable. Therefore, the gas filtration device 100 disclosed in this application can solve the problem that the gas filtration device in the related art needs to frequently clean or replace the filter element 120.
[0030] Optionally, a part of the filter element 120 can be filled within the air flow channel 111, that is, the air flow channel 111 can be filled with the filter element 120. In this way, the contact area between the gas and the filter element 120 can be relatively large, and thus the gas filtration effect is relatively good. Moreover, the driving mechanism 130 can drive the filter element 120 to slide along the extending direction of the air flow channel 111, so that different parts of the filter element 120 enter the air flow channel 111, and then different filter areas of the filter element 120 filter the gas.
[0031] Optionally, a part of the filter element 120 can pass through the air flow channel 111, that is, a part of the filter element 120 can pass through the air flow channel 111 along the extending direction of the cross-section of the housing 110. Specifically, the housing 110 is provided with a horizontal sliding hole along the direction where the cross-section of the housing 110 extends. This sliding hole passes through the air flow channel 111, and a part of the filter element 120 can be laid flat within the sliding hole. At this time, when the gas moving within the air flow channel 111 passes through the sliding hole, it can pass through the filter element 120 and be filtered by the filter element 120. In this embodiment, since a part of the filter element 120 is laid flat within the sliding hole of the housing 110, it makes it easier for the driving mechanism 130 to drive the filter element 120 to slide relative to the air flow channel 111.
[0032] Optionally, the housing 110 has a top surface 114 and a bottom surface 115 arranged opposite to each other. A first air inlet 112 may be provided on the bottom surface 115, and a first air outlet 113 may be provided on the top surface 114.
[0033] In another embodiment, at least two first air inlets 112 spaced apart may be provided on the bottom surface 115, and at least two first air outlets 113 spaced apart may be provided on the top surface 114. The efficiency of gas entering the air flow channel 111 can be improved through the multiple first air inlets 112, and the efficiency of gas discharging from the air flow channel 111 can be improved through the multiple first air outlets 113. That is, this setting method can improve the efficiency of the gas filtering device 100 in processing gas.
[0034] Optionally, the air flow channel 111 may be a horizontal channel, and the air flow channel 111 may extend along the extension direction of the cross-section of the housing 110.
[0035] In another embodiment, the air flow channel 111 may be a curved channel. The curved air flow channel 111 has a guiding effect on the gas, and moreover, the curved air flow channel 111 can accommodate more gas, so that the gas filtering device 100 can process more gas simultaneously, thereby meeting the user's usage requirements.
[0036] Specifically, the air flow channel 111 may include at least two first channels 1111 close to the top surface 114 and at least two second channels 1112 close to the bottom surface 115. That is, with respect to the second channels 1112, each first channel 1111 is arranged closer to the top surface 114, and with respect to the first channels 1111, each second channel 1112 is arranged closer to the bottom surface 115. The first channels 1111 and the second channels 1112 are connected in sequence, and each first air inlet 112 corresponds to and is connected to a second channel 1112, and each first air outlet 113 corresponds to and is connected to a first channel 1111. At the same time, each first air inlet 112 is used to communicate with the second air inlet 210, and each first air outlet 113 is used to communicate with the second air outlet 220.
[0037] Optionally, please refer to Figure 1, the second channel 1112 at one end of the air flow channel 111 can be a vertical air flow channel 111, and the first channel 1111 at the other end of the air flow channel 111 can be a vertical air flow channel 111 or an L-shaped air flow channel 111. Except for the second channel 1112 and the first channel 1111 at both ends of the air flow channel 111, the shapes of all the other first channels 1111 and second channels 1112 can be U-shaped, that is, all the other first channels 1111 and second channels 1112 are U-shaped air flow channels 111. The adjacent first channels 1111 are connected by the second channels 1112, and the adjacent second channels 1112 are connected by the first channels 1111. That is, after the first channels 1111 and the second channels 1112 are connected in sequence, a bent air flow channel 111 can be formed. Of course, the shapes of all the other first channels 1111 and second channels 1112 can be S-shaped or wavy.
[0038] Optionally, please refer to Figure 1 , Figure 4 and Figure 5 , the gas filtering device 100 may further include a winding mechanism 140. The winding mechanism 140 and the driving mechanism 130 are arranged at intervals in the air conditioner. Specifically, the winding mechanism 140 and the driving mechanism 130 may be located on opposite sides of the housing 110. Specifically, the winding mechanism 140 may include a first mounting bracket 141 and a winding roller 142. The first mounting bracket 141 is arranged on the inner wall of the air conditioner, and the winding roller 142 is rotatably arranged on the first mounting bracket 141. One end of the filter element 120 is connected to the winding roller 142, and a part of the filter element 120 is wound around the winding roller 142. That is, the winding roller 142 can wind the filter element 120. The other end of the filter element 120 passes through the first side plate 116, the air flow channel 111 and the second side plate 117 of the housing 110 in sequence and is connected to the driving mechanism 130. The first side plate 116 and the second side plate 117 are located on opposite sides of the housing 110, so that the winding mechanism 140 and the driving mechanism 130 are also located on opposite sides of the housing 110.
[0039] In this embodiment, when the driving mechanism 130 drives the filter element 120 to move, the amount of the filter element 120 wound around the winding roller 142 will gradually decrease. Different parts of the filter element 120 will enter the air flow channel 111 through the openings on the first side plate 116, and the used filter element 120 will slide out of the air flow channel 111 through the openings on the second side plate 117. In addition, since the winding roller 142 can wind the filter element 120, the present application can provide a larger size or a greater amount of the filter element 120 in the air conditioner. The filter element 120 is wound around the winding roller 142 to make the filter element 120 arranged more compactly, so that the overall occupied space is smaller. And providing a larger size or a greater amount of the filter element 120 in the air conditioner can increase the usage time of the filter element 120 to further reduce the frequency of replacing or cleaning the filter element 120. Of course, the gas filtering device 100 may not include the winding mechanism 140 either.
[0040] Optionally, the present application can control the rotation of the winding roller 142 through a motor, so that when the driving mechanism 130 drives the filter element 120, the winding roller 142 will not rotate too fast following the filter element 120. As a result, the winding roller 142 will not release too much of the filter element 120. That is, this setting method can make the winding roller 142 release the filter element 120 stably and make the filter element 120 released by the winding roller 142 always in a taut state, thus facilitating the more stable movement of the filter element 120.
[0041] In another embodiment, the present application can control the rotation of the winding roller 142 through a torsion spring 143. That is, the winding mechanism 140 can further include a torsion spring 143. The torsion spring 143 is sleeved outside the winding roller 142, and one end of the torsion spring 143 is connected to the winding roller 142, and the other end of the torsion spring 143 is connected to the first mounting bracket 141. When the driving mechanism 130 drives the filter element 120 to move, the filter element 120 will drive the winding roller 142 to rotate. Under the limiting action of the torsion spring 143, the winding roller 142 will not rotate too fast, which makes the filter element 120 released by the winding roller 142 always in a taut state. In this embodiment, since the rotation of the winding roller 142 is controlled by the torsion spring 143, the overall control difficulty is relatively low. And this setting method makes the overall structure relatively simple while reducing the production cost.
[0042] Optionally, the first end of the winding roller 142 passes through the first mounting bracket 141, and a baffle 144 is protrudingly provided at the first end of the winding roller 142. The baffle 144 and the filter element 120 are located on two opposite sides of the first mounting bracket 141, and the torsion spring 143 is located between the baffle 144 and the first mounting bracket 141, so that the torsion spring 143 and the filter element 120 are located on two opposite sides of the first mounting bracket 141. The baffle 144 can prevent the torsion spring 143 from detaching from the winding roller 142, and one end of the torsion spring 143 is connected to the baffle 144. In this embodiment, since the torsion spring 143 and the filter element 120 are located on two opposite sides of the first mounting bracket 141, that is, on different sides of the first mounting bracket 141, when the filter element 120 accidentally slides on the winding roller 142, it can be avoided that the filter element 120 contacts the torsion spring 143, resulting in the situation that the torsion spring 143 damages the filter element 120. That is, this setting method can avoid damaging the structure of the filter element 120, thereby avoiding affecting the filtering function of the filter element 120. Of course, the torsion spring 143 and the filter element 120 can also be located on the same side of the first mounting bracket 141. At this time, a preset distance can be provided between the torsion spring 143 and the filter element 120, and the preset distance can be set to be relatively large.
[0043] Optionally, the driving mechanism 130 can be a telescopic driving component. In the initial state, the end of the telescopic driving component can be in the extended state. When the telescopic driving component retracts, the end of the telescopic driving component can drive the filter element 120 to move relative to the air flow channel 111.
[0044] In another embodiment, the driving mechanism 130 can be a driving component for winding the filter element 120. Specifically, the driving mechanism 130 can include a second mounting bracket 131, a mounting roller 132, and a driving member. The second mounting bracket 131 and the driving member are both provided on the air conditioner. The mounting roller 132 is rotatably provided on the second mounting bracket 131. One end of the filter element 120 is connected to the mounting roller 132, and the driving member is connected to the mounting roller 132 to drive the mounting roller 132 to drive the filter element 120 to slide relative to the air flow channel 111. During the rotation of the mounting roller 132, a part of the filter element 120 can be wound around the mounting roller 132. That is, a relatively large amount of the used filter element 120 can be wound by the rotatable mounting roller 132. And because the filter element 120 will be wound on the mounting roller 132, the overall structure of the used filter element 120 is relatively compact, and thus the overall occupied space is relatively small.
[0045] Optionally, the driving member may include a driving rod 133. One end of the driving rod 133 is connected to the mounting roller 132. The other end of the driving rod 133 passes through the housing 200 of the air conditioner, and the driving rod 133 is rotatably disposed in the housing 200, that is, a part of the driving rod 133 is disposed outside the air conditioner. Optionally, an operating portion 136 may be provided at the other end of the driving rod 133. The user manually drives the operating portion 136 to rotate, thereby manually driving the driving rod 133 to rotate, and further driving the mounting roller 132 to rotate through the driving rod 133, so as to ensure the movement of the filter element 120 relative to the air flow channel 111. That is, this setting method can facilitate the user to determine whether the filter element 120 moves relative to the air flow channel 111. Of course, the entire driving rod 133 may be disposed inside the air conditioner. At this time, a driving source with a driving function such as a motor or a cylinder disposed inside the air conditioner may be used to drive the driving rod 133 to rotate, thereby driving the mounting roller 132 to rotate through the driving rod 133.
[0046] Optionally, please refer to Figure 1 , Figure 6 and Figure 7 , a turbine 134 may be provided at the end of one of the driving rod 133 and the mounting roller 132, and a worm 135 may be provided at the end of the other of the driving rod 133 and the mounting roller 132. The turbine 134 and the worm 135 are engaged with each other, so that the driving rod 133 can drive the mounting roller 132 to rotate, and the transmission stability of the entire transmission process can be improved by adopting the method of using the turbine 134 and the worm 135 to transmit the driving force of the driving rod 133.
[0047] Optionally, the present application also discloses an air conditioner, including a housing 200 and the gas filtering device 100 described above. The housing 200 is provided with a second air inlet 210 and a second air outlet 220 which are spaced apart. At least a part of the gas filtering device 100 is disposed inside the housing 200, and the first air outlet 113 is communicated with the second air outlet 220, and the first air inlet 112 is communicated with the second air inlet 210. Specifically, the first air inlet 112 and the second air inlet 210 may be oppositely disposed to communicate with each other.
[0048] Optionally, both the first air inlet 112 and the second air inlet 210 extend along a first direction. The first direction may be the length direction of the first air inlet 112 and the second air inlet 210. And in this first direction, the first air inlet 112 has a first dimension, and the second air inlet 210 has a second dimension. The first dimension may be smaller than the second dimension.
[0049] In another embodiment, the first dimension is greater than or equal to the second dimension. At this time, since the first air inlet 112 and the second air inlet 210 are oppositely arranged, the first air inlet 112 can just cover the second air inlet 210, so that the two are connected and communicated. Thus, it can be ensured that the gas entering from the second air inlet 210 can enter the air flow channel 111 through the first air inlet 112, that is, the gas entering from the second air inlet 210 can be filtered by the gas filtering device 100.
[0050] Optionally, the air conditioner may further include a refrigerating component and a heating component. The refrigerating component and the heating component are arranged at intervals in the housing 200, and the gas discharged through the first air outlet 113 can be processed by the refrigerating component or the heating component and then discharged to the outside of the air conditioner through the second air outlet 220.
[0051] In the above embodiments of the present application, the differences between the embodiments are mainly described. As long as the different optimization features between the embodiments are not contradictory, they can be combined to form a more optimal embodiment. For the sake of brevity of the description, they will not be elaborated here.
[0052] The above description is only for the embodiments of the present application and is not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
