摘要:
Vacuum cleaner filters, in particular replaceable vacuum cleaner filters suitable for both dry and wet/dry type vacuum cleaners are disclosed, as well as systems incorporating the use of such filters and methods for their use. The filters include a plurality of adjacently positioned pleats arranged in a closed circumferential, cylindrically-shaped path, a top end cap having a central orifice capable of constricting a post on a vacuum filter cage, and optionally a molded end ring oppositely-spaced from the top end cap for engagement with the motor housing of a vacuum cleaner.

A floor brush nozzle assembly for a vacuum cleaner is disclosed. The floor brush nozzle assembly includes an elongated generally rectangular shaped nozzle housing including a connecting passageway for association with the vacuum cleaner. A U-shaped channel surrounds the nozzle housing for receiving an upper formed end of a floor brush. The U-shaped channel includes peripherally spaced ribs that cause a complementary U-shaped formed end of the floor brush to releasably and resiliently engage undercut areas in the U-shaped channel for releasably mounting the floor brush relative to the nozzle housing. The upper formed end of the floor brush may also have an undercut configuration to enhance releasable engagement with the undercut areas in the U-shaped channel. The upper formed end of the floor brush is preferably a metal component while the nozzle housing is a molded plastic component. In order to pick up fine debris as well as larger media such as rocks or wood chips, the floor brush may be provided with shorter leading bristles and longer trailing bristles for this purpose.

A hose clip for flexible hose of the type used in vacuum cleaners or the like is disclosed. The hose clip engages and holds two flexible hose sections in juxtaposed relationship to one another. The hose clip is an integrally molded one-piece plastic clip having opposed generally C-shaped sections which are constructed, arranged and dimensioned to resilient engage, grip and hold the two flexible hose sections in juxtaposed relationship to one another. One of the generally C-shaped sections is dimensioned to securely grip one of the flexible hose sections and prevent easy removal thereof, while the other generally C-shaped section is dimensioned to allow easy insertion and removal from the other flexible hose, to facilitate storage and/or subsequent ready access and availability of the flexible hose sections, for use.

A vacuum appliance capable of picking up both wet and dry material is described, wherein the vacuum appliance includes an impeller configured to induce liquid into the vacuum appliance, a motor configured to turn the impeller, a restrictor assembly to prevent the liquid from being ingested into the motor, and a bypass vent assembly configured to allow sufficient air to reach the motor in order to keep the motor cool while the restrictor is preventing the liquid from being ingested into the motor. The vacuum appliance also includes a drum configured to retain the liquid and an impeller intake between the impeller and the drum. The restrictor may comprise a float configured to rise with a level of the liquid in the drum and prevent the liquid from entering the impeller intake. The bypass vent assembly may be configured to allow airflow to bypass the restrictor and/or the drum.

The present disclosure provides a method, apparatus, and system to switch between direct current (DC) and alternating current (AC) power sources for appliances with a third position to allow on-board recharging of the DC power source. The method involves locking out a power source when the other power source is powering the appliance and locking out both power sources from operating the appliance when the appliance is being recharged. The DC power source can remain coupled to the appliance during operation and during recharging without necessitating removal for remote recharging by the use of a unique switch.
摘要:
An adapter for connecting a hose to a hose receptacle of an object in a locking relationship. The adapter includes a first end adapted to be fixedly attached to one of the hose receptacle or the hose and a second end having a first locking element adapted to selectively engage a second locking element to establish a locking relationship. The adapter is suitable for adapting a friction-based vacuum appliance hose connection receptacle such that it can be used with a hose-locking mechanism to selectively, securely lock the hose to the vacuum appliance.
