Rotary nozzle structure with load member

This embodiment relates to a nozzle structure, and more particularly to a rotary nozzle structure having a load member.

With the improvement of the quality of life of clothing, food, shelter and entertainment, various vehicles have also been upgraded from bicycles and locomotives to cars and recreational vehicles. When vehicles are on the road, it is inevitable that they will be exposed to sand and dirt. Therefore, after the vehicle has been driving for a period of time, it must be cleaned and brushed to keep the car body clean. Therefore, many car owners will use the holiday to send the vehicle to the car wash for cleaning. When cleaning the body of the vehicle, the manufacturer uses the foam to adhere to the cleaning agent to scrub the body, and then rinses the detergent foam with a water column through a water pipe. However, in the cleaning process, the water column of the water pipe is often insufficient, so that the dust on the car body is not easy to clean, and the mark of dust and sand will remain after the vehicle is cleaned.

Therefore, some manufacturers have developed an air spray gun or an air spray gun to use high-pressure air to improve the cleaning effect of the air spray gun or air spray gun. The air spray gun or the air spray gun is connected to a grip, a liquid cylinder and a nozzle by a T-shaped tube, and the bottom of the grip is connected to a nozzle to an air compressor. The grip controls the high pressure air of the air compressor into the T-tube to generate a Venturi Effect to pour out the liquid in the liquid cylinder and then spray it outward from the nozzle.

However, air spray guns or air spray guns have only a small area of spray area. Therefore, if the cleaning staff wants to use the air spray gun or air spray gun to quickly enter When cleaning a large area, it is easy to skip a part of the cleaning area by swiftly sweeping, resulting in an area that is not cleaned. As a result, the cleaning staff must spend a lot of time repeatedly cleaning the same area to maintain a good cleaning effect. Therefore, how to improve the overall cleaning ability of the air spray gun has become a problem that designers need to solve at present.

In view of the above problems, the present invention relates to a rotary nozzle structure with a load member, thereby improving the problem that the overall cleaning ability of the air spray gun is insufficient.

Additionally, the spoiler 30 has a bent structure adjacent the exit end 302. In more detail, the spoiler 30 has a bent pipe body 310 that is connected and pivoted, and a combined pipe body 320. The bent pipe body 310 and the combined pipe body 320 together form a spoiler 300. The outlet end 302 is located at one end of the bent pipe body 310, and the joint end 304 is located at one end of the joint pipe body 320. In other words, the outlet end 302 and the binding end 304 are not located in the same On one axis, an injection path A when the high flow rate gas is ejected from the outlet end 302 is at an acute angle θ with an axis B of the gas flow tube 10.

When the bent tubular body 310 is pivoted relative to the combined tubular body 320, the outlet end 302 is circumferentially moved about the axis B. When the high flow rate gas flows through the spoiler 300 to the outlet end 302, the high flow rate gas simultaneously produces a reaction force to the outlet end 302. Since the outlet end 302 is not located on the axis B, and the injection path A is also not parallel to the axis B, when the reaction force acts on the outlet end 302, the outlet end 302 is in an eccentrically stressed state. The body 310 pivots relative to the tubular body 320.

The flow tube 40 has an opposite liquid inlet end 400 and a liquid outlet end 410. The liquid inlet end 400 is located outside the gas flow tube 10, and the liquid inlet end 400 is located in the liquid storage tank 80. The cleaning liquid 800, such as water, soap liquid, cleaning liquid, and the like, is stored in the liquid storage tank 80, and the liquid flow tube 40 draws the cleaning liquid 800 by the liquid inlet end 400. In addition, the gas flow tube 10 has an annular side wall 130 that forms the air flow path 100. The annular sidewall 130 has a perforation 132 that communicates with the airflow passage 100. The liquid outlet end 410 of the flow tube 40 enters the air flow path 100 via the perforation 132, and the liquid discharge end 410 extends from the air flow path 100 to the outlet end 302 of the spoiler 300. In addition, the rotating spray head structure 5 with the load member further includes a stop member 90, and the stop member 90 is located in the through hole 132. The leak stop 90 is used to seal the gap between the liquid flow tube 40 and the perforation 132 to prevent gas in the air flow path 100 from leaking out of the gap between the liquid flow tube 40 and the perforation 132.

The load member 50 is mounted to the second end 210 of the rotating member 20. In this embodiment, the load member 50 covers the spoiler 30, but is not limited thereto. In this embodiment and other embodiments, the load member 50 is used to increase the weight of the rotating member 20 to increase the rotation of the rotating member 20. Torque, the detailed connection relationship between the load member 50 and the spoiler 30 is not intended to limit the present invention. Further, in the present embodiment, the load member 50 is, for example but not limited to, a spring. Since the load member 50 is mounted on the rotary member 20, the load of the rotary member 20 is increased to increase the torsion of the rotary member 20, so that the overall cleaning ability of the rotary spray head structure 5 having the load member can be improved.

In this embodiment and other embodiments, the rotary spray head structure 5 with the load member further includes a nozzle cover 60. The nozzle shield 60 has a nozzle opening 600. The nozzle cover 60 has an opposite third end 610 and a fourth end 620. The nozzle opening 600 is located at the fourth end 620, and the opening outer diameter of the third end 610 of the nozzle mask 60 is smaller than the opening of the fourth end 620. Outer diameter. The nozzle cover 60 is sleeved at the outlet end 120 of the gas flow tube 10 at a third end 610 such that the spoiler tube 30 is located within the nozzle shield 60 and the outlet end 302 of the spoiler tube 30 corresponds to the nozzle opening 600. Moreover, when the outlet end 302 of the spoiler 30 rotates about the axis B, the maximum rotational diameter of the outlet end 302 is less than the diameter of the nozzle opening 600, so the outlet end 302 does not interfere with the nozzle opening 600.

When the high flow rate gas sequentially enters the airflow path 100, the spoiler 300, and the liquid discharge end 410 of the liquid flow tube 40 in the spoiler 300 from the intake end 110, the flow tube 40 in the spoiler 300 A Venturi effect occurs at the liquid discharge end 410 such that the pressure at the liquid discharge end 410 is less than the pressure at the liquid feed end 400. As a result, due to the influence of the pressure difference between the liquid discharge end 410 and the liquid inlet end 400, the cleaning liquid 800 in the liquid storage tank 80 is sucked by the liquid inlet end 400 to the liquid discharge end 410 to be discharged. Next, the cleaning liquid 800 is mixed and atomized with the high flow rate gas in the spoiler 300, and the gas-liquid mixed washing water column is ejected from the outlet end 302.

Since the load member 50 is mounted on the rotary member 20, the load of the rotary member 20 is increased to increase the torsion of the rotary member 20, so that the overall cleaning ability of the rotary spray head structure 5 having the load member can be improved. While the cleaning liquid 800 and the high flow rate gas are ejected from the outlet end 302, the outlet end 302 is rotated about the axis B, so that the gas-liquid mixed cleaning water column is continuously ejected in a swirling type. And the cleaning area is increased by the swirling spray type cleaning water column to raise the spray area of the rotary head structure 5 with the load member. In addition, the nozzle cover 60 is used to protect the spoiler 30 to prevent the bent pipe body 310 of the spoiler 30 from being damaged by the external force when it is pivoted relative to the combined pipe body 320. On the other hand, the nozzle shroud 60 further limits the spray range of the outlet end 302 to avoid extensive and uncontrolled spraying of the wash water column, thereby affecting the operator's operation.

Please refer to the following table. The following table shows the same amount of air in the rotary nozzle structure 5 with the load member and the rotary nozzle structure without the load member, the air volume, the rotation speed when there is no water, the rotation speed when boiling water, and Comparison of water consumption time.
