Description

Technical Field

[0001] This utility model relates to the field of high-pressure cleaning technology for automobiles, and specifically to a nozzle for a high-pressure cleaner. Background Technology

[0002] Low-voltage electrical wiring for automobiles refers to wiring harnesses with a nominal voltage of less than 50V used in automotive electrical systems, including single wires. These wiring harnesses are responsible for connecting various electrical and electronic devices in the vehicle to enable the transmission of signals and energy. They are typically composed of multi-core copper wires, including a metallic conductor and an insulating outer layer.

[0003] The applicant discovered through a search that a Chinese patent, "A Nozzle for a High-Pressure Washer," with publication number "CN212702486U," discloses a nozzle for a high-pressure washer, belonging to the field of cleaning machine devices. It includes a nozzle head and a connecting pipe. The nozzle head has a water inlet and a water outlet. The water inlet of the nozzle head is fixedly connected to the connecting pipe. The water outlet of the nozzle head is provided with a first water passage hole and several second water passage holes. A cover plate is hinged to the periphery of the water outlet of the nozzle head. The cover plate is provided with a through hole and several connectors for inserting into the second water passage holes. The cover plate is provided with a first threaded hole, and the water outlet is provided with a second threaded hole. When the cover plate and the water outlet of the nozzle head are parallel, the through hole aligns with the first water passage hole, and the first threaded hole aligns with the second threaded hole. This utility model not only has a simple structure and reasonable design, but also enables the conversion between single-hole and multi-hole nozzles.

[0004] The aforementioned device uses a cover plate to control the water flow on one side. However, when the water flow is large, the cover plate is easily impacted and falls off, making it impossible to achieve single-hole drainage. Utility Model Content

[0025] In this embodiment, the spraying device 2 includes: a spray head 201 fixedly installed on one side of the connecting pipe 1, a spraying channel 202 opened inside the spray head 201, and a spraying control component 203 assembled on one side of the spray head 201.

[0026] In this embodiment, the spray control component 203 includes: a slot 204 formed on the spray head 201; a main spray port 205 formed on one side of the spray head 201; a secondary spray port 206 formed on one side of the spray head 201; four sets of secondary spray ports 206 formed on one side of the spray head 201; and the four sets of secondary spray ports 206 are equidistantly formed on one side of the spray head 201.

[0027] In this embodiment, the flow rate control device 3 includes: an adjustment channel 301 assembled on one side of the connecting pipe 1, a water injection pipe 302 fixedly installed on one side of the adjustment channel 301, a connecting pipe 303 fixedly installed on one side of the adjustment channel 301, and one side of the connecting pipe 303 fixedly connected to the connecting pipe 1.

[0028] In this embodiment, the flow rate control device 3 further includes: a movable ball 304 movably installed inside the adjustment channel 301, a screw 305 threadedly connected to the top of the adjustment channel 301, and a knob 306 fixedly installed on the top of the screw 305.

[0029] In this embodiment, the flow rate control device 3 further includes: a movable ball 307 movably installed inside the adjustment channel 301, a screw 308 threadedly connected to the bottom of the adjustment channel 301, and a knob 309 fixedly installed at one end of the screw 308.

[0030] When using the device, liquid is first injected into the connecting pipe 1 through the water injection pipe 302. By rotating knob 306, screw 305 drives movable ball 304 to move up and down within the adjustment channel 301, thereby adjusting the liquid flow rate. Simultaneously, rotating knob 309 causes screw 308 to move movable ball 307, further precisely controlling the flow rate. The adjusted liquid flows into the spray channel 202 of the spray head 201 through the connecting pipe 303. The slot 204 in the spray control assembly 203 allows the spray head 201 to be installed and removed as needed. The liquid is finally sprayed out through the main spray nozzle 205 and four sets of equidistantly distributed secondary spray nozzles 206, achieving uniform spraying.

[0031] Example 2

[0032] like Figures 1 to 5 As shown, in a first aspect embodiment of the present invention, a nozzle for a high-pressure washer, the water flow control device 4 includes: a locking block 401 detachably installed inside a slot 204, a spring 402 fixedly installed on one side of the locking block 401, and a baffle 403 fixedly installed on one side of the spring 402.

[0034] When using the nozzle of this high-pressure washer, first insert the locking block 401 into the slot 204 of the spray head 201. At this time, the spring 402 is in its natural state, and the baffle 403 blocks the spray nozzle 404. When water flows into the spray head 201 through the connecting pipe 1, the water pressure pushes the baffle 403, compressing the spring 402, and the water flows out through the spray nozzle 404. At the same time, the water pressure also acts on the locking block 406, compressing the spring 405. The locking block 406 contracts inward, and the water flows out further through the gap between the locking block 406 and the baffle 403, achieving dual control of the water flow and a more uniform spraying effect.
