Description

Technical field

[0001] The invention relates to a brush attachment for a hand blender, also known as a one-handed blender, magic wand or immersion blender, which can be used in particular for cleaning cookware (e.g. pots, pans), kitchen surfaces (e.g. baking trays), household surfaces and vehicle surfaces (e.g. headlights, car rims).

[0002] The brush attachment is designed for use with standard hand blenders, which are usually equipped with a bayonet fitting and are electrically powered by mains adapter or battery. State of the art

[0003] For cleaning dirty pots, pans, or baking trays, commercially available dish sponges with an abrasive side, steel wool pads such as AKO Pads or Abrazo are used. Electric cleaning brushes are also available on the market.

[0004] Well-known immersion blenders are used as kitchen appliances for chopping and pureeing, whipping or emulsifying foods such as cream or egg whites.

[0005] Cleaning soiled surfaces typically requires considerable manual effort. Currently, no brush attachments for hand blenders are known to offer mechanical assistance in cleaning soiled pots, pans, or painted metal sheets. Object of the invention

[0006] The aim is to create a universal attachment for commercially available hand blenders that enables a simple, hygienic, interchangeable brush cleaning system and safe cleaning of cookware and surfaces. Description of the invention / Solution to the problem

[0007] The task is solved by a brush attachment with a detachable connection to the drive shaft / drive unit of the hand blender.

[0008] The invention relates to a brush attachment (1) that can be attached to commercially available stick blenders, one-handed mixers, magic wands or immersion blenders.

[0009] The fastening can be done optionally by means of • a magnetic connection (3, 5), or • a mechanical threaded connection (6), • a bayonet fitting (2), • a click system (15), • via a striking disc (14), - directly onto the drive shaft (4).

[0010] A hand blender typically consists of two main components: 1. the upper part - the handpiece (20) with the integrated motor, and 2. the lower part - the mixing foot (19) (also called the drive unit) in which the drive shaft is located, at the end of which there is typically a blade or stirring unit.

[0011] In a first embodiment, the brush attachment can be designed as an integral part of a specially designed drive unit (mixing foot). In this case, the brush is permanently connected to the mixing foot, so that no change between different attachment tools is possible. The mixing foot thus designed can be connected directly to the upper motor part of the hand blender by means of a bayonet fitting (2) or an equivalent coupling mechanism.

[0012] In a second embodiment, the existing blade unit or beater disc (14) is removed, and the brush attachment (1) is placed, attached or screwed directly onto the drive shaft (4) of the mixing foot using a bayonet fitting or a click system.

[0013] In a third embodiment, the brush attachment can be arranged on an existing impact disc, which serves as a support or coupling element. The connection can be, for example, magnetic, mechanically locking, or pluggable.

[0014] In a first variant of this third embodiment, a magnetic metal plate is located on the drive shaft (3), on which a brush unit with a ferromagnetic counter plate is attached.

[0015] In a second variant of this third embodiment, the magnet is located in the brush unit (5), while the drive shaft carries a ferromagnetic metal plate. This could, for example, be a striking disc provided with positive locking mechanisms.

[0016] To improve adhesion and operational reliability, especially with magnetic connections, positive locking mechanisms are provided between the connecting surfaces for additional anti-rotation protection. These prevent the attachment from unintentionally loosening or rotating during operation, both clockwise and counterclockwise.

[0017] In a fourth embodiment, there is no magnetic connection. Instead, a self-locking thread (6) is used which tightens itself in the direction of operation.

[0018] When the direction of rotation is changed via a toggle switch (17) on the upper part of the housing, the thread automatically loosens so that the brush attachment can be removed.

[0019] The brush attachment can be fitted with different brush units (7), including plastic, metal or steel wool brushes, polishing pads (23) or sponges. The bristles of the brush attachment can also be arranged laterally (18), for example, to better clean the corners of cooking pots.

[0020] Optionally, a gripping clamp (12) can be provided, which is connected to the drive shaft. This gripping clamp can be used to clamp standard cleaning sponges. The gripping clamp is activated by a built-in pressure mechanism on the drive shaft.

[0021] An integrated LED light (9) in the lower part of the hand blender illuminates the work area. The energy can be generated via a dynamo (10), a battery (11), or a combination of both, so that the LED can also be operated without active rotation.

[0022] Alternatively, the LED can be positioned on the upper motor part (handle) (16). The LED is oriented so that the working area is illuminated from above. The energy is supplied via the battery or power supply positioned at the top of the handpiece; a dynamo in the lower part of the immersion blender is then not necessary.

[0023] A flexible shaft (8) is provided for hard-to-reach areas. A flexible section is located at the outer end of the lower part of the hand blender, allowing the brush attachment to be bent in any direction.

[0024] The brush attachment is compatible with existing and commercially available hand blender systems, especially devices from ESGE (Zauberstab), Bosch, Philips, Braun, WMF, Kitchen-Aid and similar.

[0025] This means the brush attachment can be retrofitted to both new and existing devices. Advantages of the invention • Can be retrofitted to existing stick blenders, one-handed mixers, magic wands and immersion blender systems • Hygienic through magnetic or mechanical connection • Positive locking mechanisms to prevent rotation between the connecting surfaces • Tool-free change (magnet, click, bayonet, thread) • LED lighting with dynamo / battery unit, also without rotation • Gripping pliers for standard sponges • Flexible shaft for hard-to-reach areas • Compatible with common brands (ESGE, Bosch, Philips, Braun, Kitchen-Aid) • Expandable with polishing and cleaning attachments • Suitable for use on cookware, ovens, bathroom surfaces, car headlights and car rims
