A filter connectable to a filter housing assembly. When the filter is disconnected from the filter housing assembly, a driven cover of the filter housing assembly is in a closed position preventing unfiltered fluid from flowing through an inlet of the assembly. When the filter is connected to the filter housing assembly, a filter bag ring of the filter moves the driven cover to an open position uncovering the inlet allowing filtered fluid to flow through the inlet.

A handheld vacuum assembly for the capture and collection of small insects that includes a vacuum body defining a suction chamber, a motor operably configured to generate a vacuum downstream in the suction chamber, a funnel member defining a suction channel located downstream of the suction chamber and a suction channel area therein, a valve disposed within the suction channel that is configured to open and close to inhibit or prevent insects from leaving the funnel member, and a filter assembly disposed upstream of the suction channel, downstream of the motor, having a porous membrane member, having a filter cap selectively removably coupled to the porous membrane member and having a plurality of selectively removable strips disposed thereon and each having an adhesive surface oriented in a direction facing the distal tip of the funnel member.

A hand vacuum cleaner has a cyclone assembly comprising a cyclone and a dirt collection chamber. The cyclone assembly has a cyclone assembly axis extending centrally between a front end of the cyclone assembly and a rear end of the cyclone assembly. The cyclone has a horizontally extending cyclone axis and the dirt collection chamber has a lower end which is at a lower elevation than a lower end of the cyclone chamber. A line that extends in a common direction with the cyclone assembly axis intersects the dirt collection chamber at an elevation below the cyclone chamber, a pre-motor filter and a handle of the hand vacuum cleaner.

A hand vacuum cleaner has an airflow path from a dirty air inlet to a clean air outlet and an air treatment member provided in the airflow path. The air treatment member has a front end, a rear end, and a centrally positioned longitudinal axis extending between the front and rear ends. The hand vacuum cleaner further has a pistol grip handle and a motor and fan assembly. The motor and fan assembly has a volume and a motor axis of rotation. At least 50% of the volume is positioned in the pistol grip handle.

The invention discloses a multifunctional car vacuum cleaner, which relates to the field of car vacuum cleaners and includes a handle housing, a speed control switch, a constant current plate, a switch motherboard, a motor, a battery, a charging board, and a vacuum head. The inner side of the handle housing is fixedly mounted with a bottom plate, and the charging board is fixedly installed at the upper end of the bottom plate.

A portable surface cleaning apparatus is removably mounted from a wheeled base. The portable surface cleaning apparatus is provided with an energy storage member and a suction motor.

A changeover valve includes: a valve body and an internal-communication air duct and a driving device arranged in the valve body; wherein the valve body is connected with a housing of a vacuum cleaner, the housing is provided with a ventilation opening, an air inlet duct for driven inlet air and an air outlet duct for driven outlet air, the ventilation opening is provided with a filter element, a first end of the internal-communication air duct is connected with the ventilation opening, an outer side of the internal-communication air duct is connected with the driving device, so that the driving device drives a second end of the internal-communication air duct to rotate by a preset angle, the second end of the internal-communication air duct is connected at the air inlet duct and the air outlet duct communicates with the external space.

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 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 cleaning system achieving a plurality of cleaning paths by using a single vacuum source is disclosed, including a dust collector body, forming a first air path or serving as a component of a second air path, where the dust collector body comprises a housing, internally provided with: a dust storage cavity, provided with a dirt inlet; a vacuum source, used as a power source of the cleaning system; and a switching module is disposed between the dust storage cavity and the vacuum source, and configured to switch the first air path and the second air path; where a path of the first air path is: an air inlet-the dust storage cavity-the switching module-the vacuum source-an air outlet. The cleaning system further includes a dirt collection assembly, which is used for docking with dust collector body to form the second air path.
