Embodiment Construction

[0093] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0094] Such as figure 1 Shown is a schematic diagram of a high-pressure cleaner 1 according to an embodiment of the present invention. The high-pressure cleaner 1 is hand-held and has a handle for holding. The high-pressure cleaner 1 has a casing 10 , and the casing 10 has a motor 2 , a transmission mechanism 3 connected to the motor 2 , and a pump 4 driven by the transmission mechanism 3 . The high pressure cleaner 1 can be powered by AC or DC. Due to the requirement of hand-held portability, the high-pressure cleaner 1 itself does not have a water tank for storing water source, but is connected to an external water source through a water pipe...

Description

technical field [0001] The invention relates to a pump unit. The present invention also relates to a hand-held high-pressure cleaner, especially a hand-held high-pressure cleaner using the pump unit. Background technique [0002] In family life and outdoor activities, the need for cleaning has always been widespread. [0003] In the family life centered on the family courtyard, people often need to clean balconies, walkways, outdoor tables and chairs, barbecue grills, cars, bicycles, garages, pets, garden tools, windows, swimming pools, outdoor steps, etc. Since these items are used outside the house, they will inevitably be stained with mud, oil stains, leaves, dust and other stains. It is extremely inconvenient to clean them with a rag, and they need to be sprayed with water or even high-pressure water. In order to meet the above needs, the solution on the market is to provide household high-pressure cleaners. As disclosed in Chinese patent CN1840246A, these high-pressur...
