A dust cup assembly (100) and a handheld cleaner (1000) having the same are provided. The dust cup assembly (100) includes: a cup casing (1); a device housing (2) configured as a tube shape and disposed in the cup casing (1), wherein an outer end face of the device housing (2) at an axial side thereof abuts against or extends beyond a partial inner surface of the cup casing (1), and a dust removal chamber (A1) is defined between an inner surface of the cup casing (1) and an outer peripheral surface of the device housing (2) and surrounds the device housing (2) along a circumferential direction of the device housing (2); and a negative pressure device (3) located within the device housing (2) and enabling dusty air to enter the dust removal chamber (A1) for dust and air separation.

A filter bag configured for use in a vacuum cleaner is provided. The filter bag includes a first layer of filter material with a selected value of efficiency in removing airborne particulates, and a second layer that is impregnated with silver or a silver compound with antimicrobial properties.

The present disclosure relates to fine filter part kit (63), comprising a replacement fine filter part (15) that is adapted to be mounted to a fine filter section (12) for a dust extractor (1). The fine filter part kit (63) further comprises a filter lid (16) that is adapted to be mounted to a corresponding used fine filter part (15) to be replaced, already mounted to the fine filter section (12), and thereby seal an opening (28) of a particle containing space inside the used fine filter part (15) before removing the used fine filter part (15). In this way, release of particles contained in the particle containing space into the ambient air is prevented and a secure disposal of the used fine filter part (15) is enabled.

A method for operating a vacuum cleaning appliance, having a filter element, a filter element cleaning device, a control device, a turbine, a first pressure sensor and a second pressure sensor. The method includes operating the vacuum cleaning appliance to suck in the air stream through the filter element; determining a first pressure reference value; measuring the pressure difference between the first and second pressure values; dedusting the filter element with the aid of the filter element cleaning device if the value of the pressure difference between the first and second pressure values reaches a first threshold value; determining a second pressure reference value after the end of the dedusting of the filter element; determining a difference value between the second and first pressure reference values; and dedusting the filter element if the difference value between the second and first pressure reference values reaches a second threshold value, or switching off the vacuum cleaning appliance if the difference value between the second and first pressure reference values reaches a third threshold value. A vacuum cleaning appliance for carrying out the method.

A vacuum cleaner for air pollution prevention includes a main body, a blower, a filtering and cleaning assembly, and a gas detection module. The main body is configured to form a flow-guiding path. The blower is disposed in the flow-guiding path to guide air convection. The filtering and cleaning assembly is disposed in the flow-guiding path to filter and clean the air pollution source in the air guided by the blower. The gas detection module is disposed in the flow-guiding path to detect the air pollution source and transmits a gas detection data.

A filter system for a vacuum cleaner is disclosed. The system comprises a housing reconfigurable relative to a bin between an operative configuration in which the housing is disposed upon the bin so that dirt separated from dirt-laden air can collect in the bin, and an idle configuration in which the housing is removed from the bin. The housing comprises an inlet for receiving dirt-laden air into the housing, an outlet via which cleaned air can exit the housing. The system further comprises first filtering means and second filtering means disposed within the housing, the first filtering means being positioned upstream of the second filtering means. The first and second filtering means comprises a filter medium configured to separate dirt from the dirt-laden air passing from the inlet to the outlet through the filter medium. The system further comprises filter cleaning means for removing dirt from the filter medium of the first filtering means when the housing is configured at least in the operative configuration.

A dust collector (1) is provided with a tank section (10) and a head section (20). The tank section (10) has a dust collection chamber (13) for containing dust. The head section (20) has a motor (23) and a dust collection fan (25). The dust collection chamber (13) has a cylindrical filter device (12) which, when air sucked in from the suction opening (11) flows through the filter device (12), separates dust from the air. A passage member (50) forms an air passage by which the outside air and a filter interior space (14) inside the filter device (12) are connected without having the filter device (12) therebetween. A cover body (60) closes the passage member (50) in an openable manner. The passage member (50) has first opening sections (53) facing the filter interior space (14) and located at different positions in the circumferential direction of the filter device (12).

A hand vacuum cleaner comprises a cyclone, a conical pre-motor filter that is positioned rearward of the cyclone and a suction motor. The pre-motor filter has a front end that faces towards the cyclone air outlet. The conical pre-motor filter has an open interior volume, an outer surface, which is an upstream surface of the pre-motor filter, and an inner surface, which is a downstream surface of the pre-motor filter.

A dishwasher comprises a tub that defines a wash space configured to accommodate one or more objects to be washed, a sump that is configured to store wash water, a water supply pump that supplies the wash water to the tub, a base that is disposed below the tub, and provides a space to accommodate the sump and the water supply pump, an air supply device that is configured to supply air to the tub, a first filter that is disposed at the base and in fluid communication with the tub and the air supply device, a second filter that is disposed at the base and in fluid communication with the tub, and a water supply that is connected to the second filter and configured to supply the wash water.
