First embodiment

As shown in fig. 1 to 3, a dust collecting apparatus according to a first embodiment of the present invention includes a filtering device, an air flow generating device 2, and a collecting unit 3.

It should be understood that in fig. 3 to 5 and later fig. 6 to 13, a dust suction apparatus according to embodiments of the present invention is more conceptually and schematically illustrated, and therefore, in fig. 3 to 13, some components are simplified or omitted as compared to fig. 1 and 2. The dust collecting device of the present application is only a customary name and does not represent that the dust collecting device can only collect dust. For the sake of simplicity, the following dust also includes other solid waste, solid and liquid mixed waste and liquid waste, such as food scraps, fruit residues, fruit juices, leaves, and the like.

It will be appreciated that the filtering means may be a cyclonic separating apparatus or a sieve, in this embodiment the filtering means is a cyclonic separating apparatus 1.

As shown in fig. 1 and 3, the airflow generating device 2 includes a motor, a fan driven by the motor, and a housing 21 surrounding the motor and the fan, and the housing 21 includes an air inlet portion 22 and an air outlet portion 23. The airflow generating device 2 can form a negative pressure near the air inlet portion 22 by the rotation of the fan, so that air is sucked into the housing 21 from the air inlet portion 22 and blown out from the air outlet portion 23.

Further, the airflow generating device 2 may further include a secondary filter device, and the air is filtered by the secondary filter device and then blown out from the air outlet portion 23. It will be appreciated that the secondary filter means is intended to further filter the air separated by the cyclonic separating apparatus 1. For example, the secondary filter means may comprise cyclonic separating apparatus or a sieve, and in this embodiment the secondary filter means comprises a sieve. Specifically, the filter screen can be HEPA filter screen or waterproof HEPA filter screen, can select according to the in-service use needs, for example, need not collect liquid can use the HEPA filter screen, need collect liquid can select waterproof HEPA filter screen. The air inlet part 22 of the air flow generating device 2 is positioned at the top or upper part of the shell 21, and the air outlet part 23 is arranged along the circumferential direction of the shell 21.

As shown in fig. 3 and 4, the air inlet part 22 of the air flow generating device 2 is communicated with the cone air outlet 13 of the cyclone separation device 1 through a pipeline 6, and the pipeline 6 is positioned between the filtering device and the air flow generating device. The conduit 6 is detachably connected to the filtering means (cyclone 1) and the airflow generating means 2. For example, the conduit 6 may be a rigid, rigid conduit. The airflow generating means 2 causes dirt-laden air to enter the cyclonic separating apparatus 1 via the airflow inlet 12. After being separated by the cyclone separation device 1, dust in the air can be discharged out of the cyclone separation device 1 through the dust outlet 11, and the air after being separated from the dust can be discharged out of the cyclone separation device 1 through the cone air outlet 13 and enter the airflow generation device 2 through the air inlet part 22.

The bottom of the housing 21 of the airflow generating device 2 is connected to the mounting seat 32, and the dust outlet 11 of the cyclone separating apparatus 1 is coupled to and communicated with the first through hole 321. It will be appreciated that the mounting of the cyclonic separating apparatus 1 to the mounting block 32 may be either a direct mounting arrangement or an indirect mounting arrangement via, for example, a sealing member.

It will be appreciated that the cyclonic separating apparatus 1 can be sealingly coupled to the first aperture 321. The sealing engagement may be a sealing engagement by a form fit, i.e. a seal which is not provided but is achieved directly by a form fit of the cyclonic separating apparatus 1 with the mounting block 32. The sealing engagement may also be a resilient engagement, i.e. at least one of the cyclonic separating apparatus 1 and the mounting block 32 is provided with a seal, the sealing engagement being achieved by deformation of the seal. It is of course also possible to achieve a sealing fit by providing a separate seal between the cyclonic separating apparatus 1 and the mounting block 32. By arranging the sealing member, the sealing performance of the collecting unit 3 can be ensured after the cyclone separating device 1 and the mounting seat 32 are mounted, and dust is prevented from flying out. Meanwhile, as the cyclone separation device 1 is communicated with the collection unit 3, the sealing effect between the cyclone separation device 1 and the collection unit 3 is ensured by arranging the sealing piece, so that the negative pressure inside the cyclone separation device 1 and the collection unit 3 is ensured, and the cleaning efficiency is ensured.

As shown in fig. 4, in the transport/storage mode, the other side of the mounting seat 32 cooperates with the collection unit 3, the mounting seat 32 having a mounting surface for mounting the filter device, said mounting surface facing the housing. The cyclonic separating apparatus 1 and the airflow generating device 2 are accommodated in the housing 31 so that the dimensions of the dust collecting apparatus in the up-down direction are reduced relative to the operating mode, and space and cost can be saved during packaging, transportation and storage.

As shown in fig. 1, the mount 32 has a shape matching the opening of the housing 31. A stepped mating portion is provided at the periphery of the opening, and the mount 32 can be attached to the mating portion. The mount 32 and the housing 31 are fixed together by a locking mechanism 4, the locking mechanism 4 being used to lock the mount 32 to the collection unit 3. The locking mechanism 4 includes a latch 42. The peripheral wall of the mount 32 is provided with a detent 41 projecting therefrom and located in the middle of the mount in the thickness direction, and the housing 31 includes the aforementioned catch 42, and the catch 42 is engageable with the detent 41 to fix the mount 32 to the housing 31 in both the operating mode and the transportation/storage mode.

As shown in fig. 1, a groove 311 is provided at the opening of the housing 31, and when the mount 32 closes the opening, the lock pin 41 is fitted into the groove 311. The lock pin 41 is located at the middle position in the thickness direction of the mount 32 so that the mount 32 closes the opening of the housing 31 regardless of the inversion, the lock pin 41 can be located at the same position in the groove 311 so that the lock catch 42 can be engaged with the lock pin 41.

As shown in fig. 3, the housing 31 may have a cylindrical shape, for example, and a garbage bag may be inserted into the cavity through the opening, and the garbage bag may be fixed by connecting the mounting seat 32 and the housing 31.

Second embodiment

The overall structure of the dust collecting apparatus of the second embodiment of the present invention is the same as that of the dust collecting apparatus of the first embodiment of the present invention. In the present embodiment, the same or similar components as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

As shown in fig. 6 to 9, the dust collecting apparatus of the second embodiment of the present invention comprises cyclonic separating apparatus 1, airflow generating means 2 and a collecting unit 3.

The airflow generating device 2 can form negative pressure near the air inlet part 22 by the rotation of the fan, so that air is sucked into the casing 21 from the air inlet part 22, filtered by the secondary filtering device and blown out from the air outlet part. The inside of the secondary dust collection unit 24 communicates with the inside of the housing 21, and dust filtered by the secondary filter device can fall into the secondary dust collection unit 24. The secondary filter means is for further filtering the air separated by the cyclone device 1. The secondary dust collecting unit is used for collecting dust collected after being filtered by the secondary filtering device.

It will be appreciated that the secondary filter means may comprise cyclonic separating apparatus or a screen, and in this embodiment the secondary filter means comprises a screen.

It will be appreciated that when the airflow generating device 2 is used alone as a dust extraction tool, the secondary filtering means is necessary because of the absence of the cyclonic separating apparatus to separate dust, and the effect is different from that of the first embodiment in that further filtering is more complicated. The secondary filtering device is, for example, a HEPA filter or a waterproof HEPA filter, and can be selected according to actual use requirements.

Further, the housing 21 and the sub dust collection unit 24 are detachably coupled, and the sub dust collection unit 24 can be detached when dust collected in the sub dust collection unit 24 needs to be dumped.

As shown in fig. 6 and 7, the dust collecting apparatus is switched between the operation mode and the transportation/storage mode by turning the mount 32 over on the housing 31. In the operating mode one side of the mounting 32 cooperates with the collecting unit 3 and in the transport/storage mode the other side of the mounting 32 cooperates with the collecting unit 3. In the operating mode, the mounting seat 32 has a mounting face for mounting the filter device, said mounting face facing away from the cavity, and in the transport/storage mode, said mounting face facing towards the cavity.
