Description

Technical Field

[0001] This utility model relates to the field of cleaning machine technology, specifically to a high-pressure cleaner handle. Background Technology

[0002] Key components of a high-pressure washer include a high-pressure pump, a control system, and nozzles. The high-pressure pump serves as the power source, pressurizing the water to a high pressure state; the control system regulates the high-pressure pump's operating status to ensure cleaning effectiveness; and the nozzles are the outlets for the high-pressure water jet, directly affecting the cleaning result.

[0003] A Chinese patent with publication number CN109229071B discloses a high-pressure washer, comprising a battery pack, an external battery casing, and a top of the battery casing being fixed to one end of a connecting pipe via a connecting base plate. Two connecting plates are assembled to a handle via an adjusting assembly. A water inlet pipe is installed on one end of the connecting pipe near the battery pack, with one end connected to a water source and the other end connected to one end of a water pipe. The water pipe passes through the inner connecting pipe of the connecting pipe, then around a motor and a high-pressure water pump, and is connected to the inlet of the high-pressure water pump. The outlet of the high-pressure water pump is connected to one end of an outlet pipe, and the high-pressure water pump is used to pressurize the water and then spray it out from the outlet pipe.

[0004] However, the handles of existing high-pressure washers have the following problems:

[0005] (1) The handle has a single function. The handle with the reel for storage and the ordinary handle without storage cannot be universal and interchangeable, resulting in high development and manufacturing costs. Customers have limited choices, which is not conducive to meeting the needs of different users.

[0006] (2) The handle is not fixed to the body with poor strength. During use, the fixing structure is prone to large gaps and breakage, and the handle fixing function is unreliable.

[0007] (3) The existing high-pressure pipe with the reel handle has no guiding structure. When reeling in the pipe, there is no fixed direction, which easily causes wear on the high-pressure pipe, resulting in a short lifespan. The pipe is messy and loose when reeling in and out, which is laborious and leads to a poor user experience.

[0008] Therefore, there is a need for a high-pressure washer handle that can be interchanged with both a standard handle and a hose reel handle, and that ensures a secure connection between the handle and the machine body, convenient high-pressure hose retraction, and extended service life, thereby improving user satisfaction.

The bottom of the handle 212 has a lip, and the front shell of the body 1 has a step that matches the lip. The lip and the step cooperate to form a U-shaped fixing and limiting connection structure 2124.

[0044] On both sides of the handle 212, symmetrical screw posts 2123 are designed. Screw holes are designed at the mating positions on the top of the front and rear shells. "Protruding ribs" that limit movement up, down, left, and right are designed symmetrically inside the two screw holes. "Protruding" grooves that mate with the front shell are designed at the mating positions. T-shaped ribs are designed at the connection positions of the two side walls, and T-shaped grooves are designed on the front shell, so that the handle 212 can be pushed into the front shell of the body assembly in the corresponding directions and fixed and limited with two self-tapping screws 28. A transverse rib connects the two screw posts 2123. A lip with a certain height is set at the bottom of the handle 212. A step and groove with mating ribs and lip are designed at the mating positions of the front shell of the body 1, so that the handle 212 and the body 1 are fixed and limited in a "U" shape in the vertical direction with a "U" shaped fixing and limiting connection structure 2124, which is fixed with self-tapping screws. Through the effective fixing in six directions (up, down, left, right, front, and back) of the above structure, the strength and reliability of the connection between the handle 212 and the body 1 are guaranteed.

[0045] The stop includes a stop ball 213, and the distance between the two guide tubes 210 is less than the outer diameter of the stop ball 213. A stop ball is installed at the connector at the pull-out end of the high-pressure pipe 27 to prevent the high-pressure pipe 27 from detaching from the guide tube connector when it is retracted. The above-mentioned high-pressure pipe guiding structure, together with the pipe reel 24, can be selectively installed according to customer requirements.

[0046] The high-pressure spray gun 3 is detachably mounted on the handle 212 via the gun mount 214, and the gun mount 214 and the crank assembly 21 are located on the same side of the handle 212.

[0047] This application allows for the detachable installation of the handle assembly onto the machine body and the detachable installation of the hose reel assembly onto the handle. The hose reel assembly is an independent component, enabling interchangeability between two configurations: a handle with a hose reel and a standard handle without a hose reel. The structure is simple, and installation, use, and replacement are convenient, meeting the needs of different customers.

[0048] This application achieves effective fixation of the handle in six directions (up, down, left, right, front, and back) by setting a fixing structure with ribs and grooves in multiple directions on the handle, and a limiting structure with the lip and step engaging, thus ensuring the strength and reliability of the connection between the handle and the machine body.

[0049] This application guides the high-pressure pipe using a guide assembly and winds the high-pressure pipe using a crank assembly and a winding wheel assembly. This not only makes it easier to pull out and wind the high-pressure pipe, but also reduces wear on the high-pressure pipe and extends its service life.
