Description

Technical Field

[0001] This utility model relates to the field of nozzle structure technology, and in particular to an adjustable nozzle for a high-pressure cleaning pump. Background Technology

[0002] The nozzle is a key component in high-pressure cleaning equipment, responsible for converting high-pressure water flow into a jet of a specific shape to achieve efficient cleaning. The nozzle of the high-pressure cleaning pump is one of the core components of the high-pressure cleaner. The nozzle bears the pressure and water jet output by the high-pressure pump and is the last step in the cleaning process. Its design directly affects the cleaning effect and efficiency. There are many types of nozzles for high-pressure cleaning pumps, including direct spray nozzles, fan-shaped nozzles and rotary nozzles.

[0003] High-pressure cleaning pump nozzles with fan-shaped nozzles can distribute water flow in a fan shape, expanding the coverage area and playing an important role in cleaning large areas such as squares and parking lots. In existing technology, narrow-angle fan-shaped nozzles with guide surfaces create a flat fan-shaped spray pattern by impacting the high-pressure water flow onto the guide surface. However, this type of fan-shaped nozzle has several problems when in use: firstly, the spray direction cannot be automatically adjusted and fixed; secondly, the guide surface is fixed and cannot be rotated to spray and expand the coverage area. Utility Model Content

[0004] The main objective of this invention is to provide an adjustable nozzle for a high-pressure cleaning pump, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An adjustable nozzle for a high-pressure cleaning pump includes a nozzle body, a threaded connector fixedly installed at the lower end of the nozzle body, a movable collar sleeved on the upper end of the nozzle body, a flow guide block fixedly installed on the upper surface of the movable collar, and a limit adjustment mechanism fixedly installed on the outer side of the nozzle body.

[0007] Preferably, the limiting adjustment mechanism includes a limiting ring, a fixed sleeve, a movable sleeve, a limiting plate, a T-shaped locking head, a short screw, a C-shaped rubber pad, and a mini motor.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, an adjustable nozzle for a high-pressure cleaning pump includes a nozzle body 1. A threaded connector 2 is fixedly installed at the lower end of the nozzle body 1, and a movable collar 3 is sleeved on the upper end of the nozzle body 1. A guide block 4 is fixedly installed on the upper surface of the movable collar 3, and a limit adjustment mechanism 5 is fixedly installed on the outer side of the nozzle body 1. When using the adjustable nozzle of the high-pressure cleaning pump, it is connected to a high-pressure cleaning machine through the threaded connector 2. High-pressure water is sprayed from the upper end of the nozzle body 1 and hits the guide surface of the guide block 4 to form a flat fan-shaped water mist. The guide block 4, in conjunction with the limit adjustment mechanism 5, enables the nozzle of the high-pressure cleaning pump to rotate and spray, and can adjust and fix the spray direction. The flat fan-shaped water mist rotates to expand the coverage area, improve dust reduction efficiency, save water and energy, improve air quality and humidity, and significantly enhance the spraying effect and application value. The movable collar 3 enables the guide block 4 to rotate under the impact of the high-pressure water flow. The guide block 4 is responsible for turning the high-pressure water flow into a flat fan-shaped water mist. The limit adjustment mechanism 5 can automatically limit the rotation of the movable collar 3 and fix the rotation angle of the guide block 4.

[0021] In this embodiment, the limit adjustment mechanism 5 includes a limit ring 501, a fixed sleeve 502, a movable sleeve 503, a limit plate 504, a T-shaped clip 505, a short screw 506, a C-shaped rubber pad 507, and a mini motor 508.

[0022] In this embodiment, the limiting ring 501 is fixedly installed on the outside of the movable collar 3. The lower surface of the limiting ring 501 is provided with a slot. There are eight slots on the lower surface of the limiting ring 501, and the slots on the lower surface of the limiting ring 501 are evenly distributed.

[0023] In this embodiment, the fixed sleeve 502 is fixedly installed on the outside of the nozzle body 1 near the upper end, the movable sleeve 503 is sleeved on the outside of the nozzle body 1 at the middle position, and the limiting plate 504 is fixedly installed on the outside of the nozzle body 1 near the lower end.

[0024] In this embodiment, the lower end of the T-shaped clip 505 is inserted into the rounded through hole of the fixed sleeve 502, the short screw 506 is provided in the threaded through hole of the fixed sleeve 502, and the C rubber pad 507 is fixedly installed on the inner side of the movable sleeve 503. The inner side of the C rubber pad 507 is in contact with the outer side of the nozzle body 1. The C rubber pad 507 plays a role in anti-slip and prevents the movable sleeve 503 from sliding down.

[0025] In this embodiment, the upper end of the T-shaped clamp 505 is inserted into the groove of the limiting ring 501, and the upper end of the short screw 506 is inserted into the groove hole of the T-shaped clamp 505. The upper end of the short screw 506 is movably connected to the upper end of the T-shaped clamp 505. A transverse groove is provided on the inner side of the C-rubber pad 507. The upper end of the short screw 506 can rotate in the groove hole of the T-shaped clamp 505. The transverse groove on the inner side of the C-rubber pad 507 increases the friction.

[0026] In this embodiment, the mini motor 508 is fixedly installed inside the movable sleeve 503, and the drive shaft of the mini motor 508 is fixed inside the short screw 506. The lower end of the T-shaped clamp 505 is fixedly connected to the mini motor 508. The mini motor 508 can drive the short screw 506 to rotate. When the guide block 4 needs to rotate freely, the mini motor 508 drives the short screw 506 to rotate downwards, and the T-shaped clamp 505 descends into the rounded through hole of the fixed sleeve 502. The movable sleeve 503 moves along... The nozzle body 1 descends to the outside until the rear end of the mini motor 508 abuts against the upper surface of the limiting plate 504. The high-pressure water flow hits the guide surface of the guide block 4, causing the movable collar 3 and the guide block 4 to rotate at the upper end of the nozzle body 1. When it is necessary to fix the guide block 4, the mini motor 508 drives the short screw 506 to rotate upward, and the T-shaped clamp 505 rises accordingly until it is inserted into the groove on the lower surface of the limiting ring 501. The limiting ring 501 is fixed, and the movable collar 3 and the guide block 4 are fixed accordingly.

[0027] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
