Description

Technical Field

[0001] This utility model relates to cleaning equipment, specifically to a mobile cleaning machine. Background Technology

[0002] The high-pressure washer includes a handheld spray gun and a water pump. The water pump is housed in a movable pump housing. The handheld spray gun is connected to the water pump via a water hose, and the water pump is connected to a water source via the same hose. A decorative cover can be installed on the outer surface of the pump housing; whether or not to include one is optional. To accommodate this option, pre-drilled holes or connectors are provided on the outer surface of the pump housing. However, this would detract from the aesthetics for users who do not require a decorative cover. Utility Model Content

[0003] The technical problem solved by this utility model is that the connection holes or connectors for the decorative cover reserved on the outer surface of the water pump housing are not aesthetically pleasing.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a decorative cover installation structure for a high-pressure washer, including a buckle and a positioning post set on the decorative cover. The water pump housing is assembled from a front housing and a rear housing. The front housing is provided with a positioning hole that cooperates with the positioning post. The outer periphery of the front housing is provided with a positioning edge. A step is formed between the positioning edge and the end face of the front housing. A buckle protrusion is provided on the step. The buckle is located at the edge of the decorative cover. The buckle can be embedded in the splice seam between the front housing and the rear housing and cooperate with the buckle protrusion.

[0005] The buckle protrusion is hidden in the seam between the front and rear housings, so the aesthetics of the pump housing are not affected even without the cover.

[0006] The positioning edge is provided with a groove, which is located below the buckle protrusion. The buckle, which is embedded in the splice seam between the front and rear housings, is positioned in the groove and cooperates with the buckle protrusion.

[0007] The clip is located at the top of the decorative cover, and the positioning post is located at the bottom. During installation, the bottom of the decorative cover is positioned by the engagement of the positioning post and the positioning hole, while the top of the decorative cover is positioned by the engagement of the clip and the clip protrusion. In this way, the decorative cover is securely attached to the water pump housing.

[0008] The positioning hole is located on the inside of the front housing. The positioning pin pierces through the front housing and engages with the positioning hole. For users who do not require a decorative cover, there is no need to pierce the front housing to expose the positioning hole, thus preserving the aesthetics of the pump housing.

[0009] The outer surface of the front housing has a recessed structure, and the decorative cover fits into the recessed structure, thus effectively positioning the decorative cover on the front housing.

[0010] The decorative cover installation structure of this utility model does not affect the aesthetics of the water pump housing, whether or not the user needs the decorative cover, before or after its installation. Attached Figure Description
