[0030] Reference Figures 1 to 4 According to the first embodiment of the present utility model, a dust collection device with an air purification function includes a main shell 110 and an operating tube 300. The main shell 110 is provided with an exhaust channel 111, and the exhaust channel 111 is provided with an exhaust device 120. The outer wall of the main shell 110 is provided with an air outlet 112 connected to the exhaust channel 111. The lower end of the main shell 110 is provided with a dust cup 210, and the dust cup 210 is provided with a filter chamber 211 connected to the exhaust channel 111. The filter chamber 211 is provided with a filter device 220. The lower side wall of the dust cup 210 is provided with a dust suction inlet 212 connected to the filter chamber 211, and the outer peripheral surface of the dust cup 210 is provided with an air purification inlet 213 connected to the filter chamber 211; the operating tube 300 can be slidably mounted on the dust cup 210 to open and close the air purification inlet 213.

[0031] In some embodiments, when the operating cylinder 300 opens the air purification inlet 213, the dust collection device can be placed through the lower side wall of the operating cylinder 300. At this time, the lower side wall of the dust cup 210 is flush with the lower side wall of the operating cylinder 300 or closer to the main housing 110 than the lower side wall of the operating cylinder 300, so as to prevent the lower side wall of the dust cup 210 from affecting the placement of the dust collection device on a flat surface such as the ground or a table through the lower side wall of the operating cylinder 300. Alternatively, in other embodiments, when the operating cylinder 300 opens the air purification inlet 213, the dust collection device can be placed through the lower side wall of the dust cup 210. At this time, the lower side wall of the dust cup 210 is flush with the lower side wall of the operating cylinder 300 or protrudes from the lower side wall of the operating cylinder 300, so as to prevent the lower side wall of the operating cylinder 300 from affecting the placement of the dust collection device on a flat surface such as the ground or a table through the lower side wall of the dust cup 210.

[0032] Reference Figure 2 and Figure 3 When the dust is collected, the dust collecting device 210 can be opened by operating the operating cylinder 300, and the dust collecting device can be placed on the ground or a table through the lower side wall of the operating cylinder 300 or the lower side wall of the dust cup 210. At this time, the dust collection inlet 212 is closed, so that the exhaust device 120 can draw air from the air purification inlet 213 when working, and the dust collecting device can perform air purification. Through the above arrangement, the dust collecting device provided by the utility model can be switched between the dust collection mode and the air purification mode by operating the operating cylinder 300. The mode switching is simple and convenient, which can meet the dust collection needs and the air purification needs, so that people do not need to configure a vacuum cleaner and an air purifier at the same time, thereby reducing the idle rate of the equipment, reducing space occupancy, and effectively improving product competitiveness.

[0033] In a specific implementation, the main housing 110 is sized to be handheld, or a handle is provided on the main housing 110 for people to hold.

[0034] Reference Figure 2 and Figure 7According to some embodiments of the present invention, the dust collection device can be placed through the lower side wall of the operating cylinder 300, and a first locking structure is provided between the operating cylinder 300 and the dust cup 210. When the operating cylinder 300 opens the air purification inlet 213, the lower side wall of the dust cup 210 is flush with the lower side wall of the operating cylinder 300 or closer to the main housing 110 than the lower side wall of the operating cylinder 300, and the dust cup 210 locks the position of the operating cylinder 300 through the first locking structure; a second locking structure is provided between the operating cylinder 300 and the dust cup 210. When the operating cylinder 300 closes the air purification inlet 213, the dust cup 210 locks the position of the operating cylinder 300 through the second locking structure. Therefore, when the vacuum cleaner is switched from the vacuum mode to the air purification mode, the second locking structure is first released to lock the operating cylinder 300, and then the operating cylinder 300 is slid downward to open the air evolution inlet, and then the position of the operating cylinder 300 is locked by the first locking structure to prevent the operating cylinder 300 from moving automatically, so that the vacuum cleaner can be placed on a flat surface such as the ground or a table through the lower side wall of the operating cylinder 300 and remain in the air purification mode; when the vacuum cleaner is switched from the air purification mode to the vacuum mode, the first locking structure is first released to lock the operating cylinder 300, and then the operating cylinder 300 is slid upward to close the air evolution inlet, and then the position of the operating cylinder 300 is locked by the second locking structure to prevent the operating cylinder 300 from moving automatically, so that the vacuum cleaner remains in the vacuum mode.

[0035] Reference Figure 2 and Figure 7According to some embodiments of the present invention, the first locking structure includes a slide groove 214, a guide portion 310, and a first locking groove 215 arranged on the side wall of the slide groove 214. The slide groove 214 is arranged in the up and down directions. One of the slide groove 214 and the guide portion 310 is arranged on the dust cup 210 and the other is arranged on the operating cylinder 300. The guide portion 310 is inserted into the slide groove 214 and can slide up and down along the slide groove 214. The second locking structure includes a second locking groove 216 arranged on the side wall of the slide groove 214. The second locking groove 216 is located on the upper side of the first locking groove 215. By rotating the operating cylinder 300, the guide portion 310 can enter the first locking groove 215 or the second locking groove 216 from the slide groove 214. Therefore, when the dust collection device switches from the dust collection mode to the air purification mode, the operating cylinder 300 is first rotated to move the guide part 310 out of the second locking groove 216 to unlock the operating cylinder 300, and then the operating cylinder 300 is slid downward to open the air evolution inlet, and then the operating cylinder 300 is rotated to move the guide part 310 into the first locking groove 215 to lock the position of the operating cylinder 300, thereby preventing the operating cylinder 300 from moving automatically, so that the dust collection device remains in the air purification mode; when the dust collection device switches from the air purification mode to the dust collection mode, the operating cylinder 300 is first rotated to move the guide part 310 out of the first locking groove 215 to unlock the operating cylinder 300, and then the operating cylinder 300 is slid upward to close the air evolution inlet, and then the operating cylinder 300 is rotated to move the guide part 310 into the second locking groove 216 to lock the position of the operating cylinder 300, thereby preventing the operating cylinder 300 from moving automatically, so that the dust collection device remains in the air purification mode. With the above arrangement, the mode switching and unlocking and locking of the operating cylinder 300 can be completed by simply operating the operating cylinder 300 . The operation is convenient and simple, and the first locking structure and the second locking structure are simple in structure.

[0036] It is conceivable that in other embodiments, the above-mentioned first locking structure and second locking structure may also be set in other ways. For example, the first locking structure includes a first magnet provided on the dust cup 210 and a second magnet provided on the operating cylinder 300, and the second locking structure includes a third magnet. When the operating cylinder 300 slides downward to open the air purification inlet 213, the first magnet and the second magnet cooperate with each other to generate magnetic damping to lock the position of the operating cylinder 300. When the dust collection device switches from the air purification mode to the dust collection mode, the user can spend a certain amount of effort to slide the operating cylinder 300 upward to close the air purification inlet 213. At this time, the second magnet and the third magnet cooperate with each other to generate magnetic damping to lock the position of the operating cylinder 300.

[0037] It should be noted that in other embodiments, the vacuum cleaner can be placed on a flat surface such as the ground or a table through the lower side wall of the dust cup 210. At this time, the operating cylinder 300 does not need to support the vacuum cleaner, and the position of the operating cylinder 300 can be locked by the friction resistance between the operating cylinder 300 and the dust cup 210 to prevent the operating cylinder 300 from moving automatically. In this way, the above-mentioned first locking structure and second locking structure do not need to be set.

[0038] Reference Figures 4 to 6 According to some embodiments of the present invention, a first sealing structure is provided between the operating cylinder 300 and the dust cup 210 or the main housing 110, and a second sealing structure is provided between the operating cylinder 300 and the dust cup 210. When the operating cylinder 300 closes the air purification inlet 213, the first sealing structure is sealed on the upper side of the air purification inlet 213, and the second sealing structure is sealed on the lower side of the air purification inlet 213. Thus, when the dust collection device is performing dust collection work, air leakage between the dust cup 210 and the operating cylinder 300 can be avoided, thereby avoiding affecting the dust collection work.

[0039] Reference Figure 4 and Figure 5 Specifically, the first sealing structure includes an elastic sealing ring 410, an annular sealing portion 113 and an annular groove 320. One of the annular groove 320 and the sealing portion 113 is set at the upper end of the operating cylinder 300, and the other is set at the main housing 110. The elastic sealing ring 410 is installed in the annular groove 320. When the operating cylinder 300 closes the air purification inlet 213, the sealing portion 113 is inserted into the annular groove 320 and abuts against the elastic sealing ring 410, thereby forming a good seal.

[0040] Reference Figure 4 and Figure 6 Specifically, the second sealing structure includes an annular sealing gasket 420, and an annular support portion 330 is provided at the lower end of the operating cylinder 300. The sealing gasket 420 is installed on the support portion 330. When the operating cylinder 300 closes the air purification inlet 213, the sealing gasket 420 abuts against the dust cup 210 to form a seal.

[0041] It should be noted that the above-mentioned first sealing structure and second sealing structure can also be set up in other ways. For example, the first sealing structure includes a first sealing ring mounted on the dust cup 210, and the second sealing structure includes a second sealing ring mounted on the dust cup 210. The first sealing ring is located on the upper side of the air purification inlet 213, and the second sealing ring is located on the lower side of the air purification inlet 213. When the operating tube 300 closes the air purification inlet 213, the first sealing ring and the second sealing ring both abut against the inner wall of the operating tube 300 to form a seal.

[0042] Reference Figure 2 and Figure 7According to some embodiments of the present invention, the upper end of the dust cup 210 is detachably connected to the main housing 110, the inlet of the filter chamber 211 is provided on the upper side wall of the dust cup 210, and the filter device 220 can be removed and installed from the inlet of the filter chamber 211. Thus, the filter device 220 can be replaced.

[0043] During the specific implementation process, the dust cup 210 and the main housing 110 can be disassembled and assembled through structures such as elastic buckles, magnetic joints, and screw-on buckles, and the dust cup 210 can be disassembled and assembled conveniently and quickly.

[0044] Reference Figure 2 and Figure 7 According to some embodiments of the present invention, the filter device 220 includes an air purification filter 221 and a dust filter 222. The air purification filter 221 is disposed in the filter chamber 211 and located at the air purification inlet 213. The dust filter 222 is disposed in the filter chamber 211 and located at the lower side of the air purification filter 221. A first connecting hole 2211 is formed in the middle of the air purification filter 221, and the first connecting hole 2211 is connected to the exhaust channel 111. With the above arrangement, the dust collection device uses the dedicated dust filter 222 to filter dust and other debris in the air during dust collection, and uses the dedicated air purification filter 221 to filter and purify the air during air purification. As a result, the filtering work in the dust collection mode and the filtering work in the air purification mode are performed by different filter components, which can better achieve the dust collection and air purification functions and reduce the impact of dust and other debris filtered out in the dust collection mode on the filtering work in the air purification mode.

[0045] Reference Figure 2 and Figure 7 In the specific implementation process, the filtering device 220 also includes a partition 223, which has a second connecting hole 2231. The above-mentioned air purification component is installed on the upper side of the partition 223, and the dust filter 222 is installed on the lower side of the partition 223. The second connecting hole 2231 is connected to the first connecting hole 2211.

[0046] Reference Figure 2 According to some embodiments of the present invention, the dust cup 210 is rotatably mounted with a valve disc 230 for opening and closing the dust inlet 212. When the exhaust device 120 is sucking dust, the valve disc 230 can be rotated to open the dust inlet 212. When the vacuum cleaner is placed on the ground or a tabletop via the lower side wall of the operating cylinder 300, the valve disc 230 can rotate under its own gravity to close the dust inlet 212. Alternatively, a reset structure is provided between the valve disc 230 and the dust cup 210, which drives the valve disc 230 to automatically rotate and close the dust inlet 212. With the above arrangement, when the vacuum cleaner is performing air purification, the valve disc 230 can close the dust inlet 212, preventing dust and other debris in the dust cup 210 from leaking out of the dust inlet 212.

[0047] Reference Figure 2 According to some embodiments of the present invention, the main housing 110 is provided with a control device 130. The exhaust device 120 includes a first fan 121 and a second fan 122 disposed in the exhaust duct 111. The first fan 121 and the second fan 122 are arranged in a vertical direction. The control device 130 can control the first fan 121 and the second fan 122 to operate simultaneously or independently. Thus, the vacuum cleaner can achieve different levels of exhaust power adjustment by controlling the operation of the two fans.

[0048] Reference Figure 2 According to some embodiments of the present invention, the power of the first fan 121 is less than the power of the second fan 122, and a mode switching switch that cooperates with the operating cylinder 300 is provided on the dust cup 210 or the main housing 110, and a gear adjustment switch 114 is provided on the main housing 110. The mode switching switch and the gear adjustment switch 114 are both electrically connected to the control device 130. The control device 130 determines whether the operating cylinder 300 opens and closes the air purification inlet 213 through the mode switching switch. When the operating cylinder 300 opens the air purification inlet 213, by operating the gear adjustment switch 114, the control device 130 can control one of the first fan 121 and the second fan 122 to work. When the operating cylinder 300 closes the air purification inlet 213, by operating the gear adjustment switch 114, the control device 130 can control the second fan 122 to work or the first fan 121 and the second fan 122 to work at the same time. Therefore, the vacuum cleaner can adjust the exhaust power to high and low levels when entering the air purification mode, and can also adjust the exhaust power to high and low levels when entering the dust collection mode. Among them, the high-level exhaust power in the air purification mode is not greater than the low-level exhaust power in the dust collection mode. Through the above settings, the vacuum cleaner can better meet people's needs: for example, at the low-level exhaust power in the air purification mode, the vacuum cleaner operates with low noise, which can meet people's low-noise needs when resting; at the high-level exhaust power in the dust collection mode, the vacuum cleaner has strong exhaust and dust collection capabilities, meeting people's needs for strong dust collection.

[0049] During specific implementation, the mode switching switch may be an inductive switch or a contact proximity switch.

[0050] It should be noted that, in other embodiments, the operating power of the fan can also be controlled by the control device 130 to achieve gear adjustment. In this case, the exhaust device 120 can be equipped with only one fan.

[0051] Reference Figure 3 and Figure 4According to some embodiments of the present invention, the vacuum cleaner further comprises a vacuum tube 500, which is detachably mounted on the vacuum inlet 212. Thus, when the vacuum cleaner enters vacuum mode, the vacuum tube 500 can be mounted on the vacuum inlet 212, making vacuuming easier.

[0052] In order to improve the portability of the vacuum cleaner, a battery is installed in the main housing 110, wherein the battery is removable and replaceable, or the battery is rechargeable, so that the vacuum cleaner can work off the power grid and is more convenient to use.

[0053] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiment is described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiment. Various changes can be made within the knowledge of ordinary technicians in the technical field without departing from the present invention.
