Description

Nozzle structure

Technical field

The present application relates to a shower head structure, particularly a shower head structure having a load member and a fan member.

Background technique

With the improvement of the quality of life of clothing, food, living, and entertainment, various modes of transportation have also been upgraded from bicycles and locomotives to cars, recreational vehicles, and so on. When vehicles run on the road, it is inevitable that they will adhere to sand and dirt. Therefore, after driving for a period of time, the vehicle must be cleaned and brushed to keep the car body clean. Therefore, many car owners will use holiday to send the car to the car wash factory for cleaning. When the operator cleans the car body, he uses foam to attach the detergent to the car body, and then rinses the detergent foam with a water column through a water pipe. However, during the cleaning process of the vehicle body, the water column strength of the water pipe is often insufficient, so that the dirt on the vehicle body is not easy to clean, and the marks of dirt and sand will still be left after the vehicle is washed.

Therefore, some industry researchers have developed an air spray gun or an air spray gun, which uses high-pressure air to improve the cleaning effect of the air spray gun or air spray gun. The air spray gun or air spray gun uses a T-shaped tube to connect a grip, a liquid cylinder and a nozzle, respectively, and the bottom of the grip is connected to a tube to an air compressor. The high-pressure air that controls the air compressor enters the T-shaped tube to produce the Venturi effect to draw out the liquid in the liquid cylinder and spray it out from the nozzle.

However, air spray guns or air spray guns have only a small spray area. Therefore, if the cleaning personnel wants to use the air spray gun or the air spray gun to quickly perform cleaning on a large area, it is easy to skip a part of the cleaning area due to rapid scanning, and then generate an unclean area. In this way, 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 becomes a problem that designers need to solve at present.

Summary of the Invention

The embodiment of the present application is to provide a spray head structure, so as to solve the problem of insufficient cleaning ability of the air spray gun in the prior art.

A spray head structure disclosed in an embodiment of the present application is used to spray a high-velocity gas and a liquid, including a gas flow tube, a rotating member, a load member, a fan member, a spoiler tube and a liquid flow tube. . The air duct has an air duct, and the air duct is used for high-speed gas circulation. The rotating member is rotatably sleeved on the air pipe. The load member is installed on the rotating member to increase the load of the rotating member and increase the torque of the rotating member. The fan member is mounted on the rotating member. The spoiler is fixed to the rotating part. The spoiler has a spoiler. The spoiler is connected to the airflow tube. The airflow channel communicates with the spoiler. The spoiler has an outlet end and the spoiler has a spray at the outlet end. The path, the jet path and an axial center of the airflow pipe are at an acute angle. The liquid flow pipe has an opposite liquid inlet end and a liquid outlet end. The liquid inlet end is located outside the air flow tube, and the liquid outlet end passes through the air flow tube to the air flow channel and extends from the air flow channel to the outlet end of the spoiler channel for It is used to spray liquid from the liquid discharge end and mix and atomize with high velocity gas. Among them, the high-velocity gas is used to spray from the airflow channel toward the outlet end, so that the spoiler rotates relative to the axis due to the eccentric force. When the rotating member rotates, it will drive the fan member to rotate to form an airflow. The outlet end is located in the flow path of the airflow.

According to the nozzle structure disclosed in the above embodiment, since the fan member and the load member are mounted on the rotating member together, when the high-velocity gas flows through the spoiler, the fan member and the load member will be driven to rotate. Among them, the rotating fan member generates an airflow, and the airflow flows from the fan member toward the outlet end to increase the liquid and high-velocity gas atomizing effect, or flows from the outlet end toward the fan member to absorb impurities adjacent to the outlet end. In addition, the load increases the load of the rotating member, so that the torque of the rotating member is increased. In this way, under the arrangement of the fan member and the load, the overall cleaning ability of the nozzle structure can be further improved.

detailed description

In order to make the purpose, technical solution, and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described in combination with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

The technical solutions provided by the embodiments of the present application will be described in detail below with reference to the drawings.

Please refer to FIG. 1 and FIG. 2. FIG. 1 is a sectional exploded view of a sprinkler structure disclosed according to a first embodiment of the present application. FIG. 2 is a schematic diagram of the operation of FIG. 1.

The spray head structure 1 of this embodiment is used for spraying a high-velocity gas and a liquid, and the spray head structure 1 can be used, for example, as a cleaning spray gun for cleaning a vehicle body. The shower head structure 1 includes an airflow pipe 10, a gas compressor 20, a rotating member 30, a spoiler pipe 40, a liquid flow pipe 50, a liquid storage tank 60, and a load member 70.

The airflow tube 10 has a through airflow channel 11. The opposite ends of the airflow tube 10 respectively have an air inlet end 12 and an air outlet end 13. The air inlet end 12 is connected to a gas compressor 20, which is used to provide a high flow rate gas.

The rotating member 30 is rotatably sleeved on the air pipe 10. In more detail, the rotating member 30 has a first end 31 and a second end 32 opposite to each other, and the rotating member 30 has a through passage 33 penetrating from the first end 31 to the second end 32. The first end 31 is rotatably sleeved on the airflow tube 10 so that a part of the airflow tube 10 is located in the through passage 33.

The spoiler tube 40 is fixed on the rotating member 30, and the spoiler tube 40 has a spoiler 41. A part of the spoiler tube 40 is connected to the airflow tube 10 so that the airflow channel 11 and the spoiler 41 communicate with each other. In detail, the spoiler 41 has an outlet end 411 and a coupling end 412 opposite to each other. The spoiler 41 and the air flow channel 11 are connected to the air outlet 13 through a joint end 412 and communicate with each other. The high-flow gas provided by the gas compressor 20 can flow through the airflow channel 11 and the spoiler channel 41 in sequence through the intake end 12 and be ejected from the outlet end 411 of the spoiler channel 41. In detail, the spoiler pipe 40 includes a bent pipe body 42 and a combined pipe body 43, and the spoiler 41 passes through the bent pipe body 42 and the combined pipe body 43. The outlet end 411 is located at an end of the bent pipe body 42 away from the combined pipe body 43, and the combined end 412 is located at an end of the combined pipe body 43 away from the bent pipe body 42, and the combined pipe body 43 is connected to the airflow pipe 10. The outlet end 411 and the coupling end 412 are not located on the same coaxial line, so that an ejection path A when a high flow rate gas is ejected from the outlet end 411 forms an acute angle θ with an axis P of the airflow tube 10.

When the high-velocity gas flows to the outlet end 411 through the spoiler 41, the high-velocity gas generates a reaction force to the outlet end 411 at the same time. Since the outlet end 411 is not located on the axis P, and the spray path A is not parallel to the axis P, when the reaction force acts on the outlet end 411, the outlet end 411 is in an eccentric force state, so that the spoiler 40 The rotating member 30 is driven to rotate together. Among them, during the rotation of the spoiler tube 40, because the high-velocity flow gas is ejected from the outlet end 411 by an acute angle θ with the axis P of the airflow tube 10, the outlet end 411 of the spoiler tube 40 surrounds The axis P performs a circular motion.

The liquid flow tube 50 has a liquid inlet end 51 and a liquid outlet end 52 opposite to each other. The liquid outlet end 52 is located outside the airflow tube 10, and the liquid inlet end 51 is located in the liquid storage tank 60. In addition, the airflow tube 10 has an annular sidewall 14 forming an airflow channel 11, and the annular sidewall 14 has a perforation 141 communicating with the airflow channel 11. In detail, the liquid flow tube 50 passes through the perforation 141 and enters the air flow path 11, and the liquid flow tube 50 extends toward the outlet end 411 of the spoiler 41 so that the liquid outlet end 52 is located outside the air flow tube 10. The liquid storage tank 60 stores cleaning liquid 2 such as water, soap liquid, cleaning liquid, and the like, and the liquid flow pipe 50 draws the cleaning liquid 2 through the liquid inlet 51. In addition, the spray head structure 1 further includes a leakage stopper 80 located at the perforation 141 to seal the gap between the liquid flow tube 50 and the perforation 141 to prevent the gas in the air flow channel 11 from leaking out of the gap.

The load member 70 is, for example, a compression spring, and the load member 70 is installed on the second end of the rotating member 30 and covers the spoiler 40 to increase the load of the rotating member 30 and increase the torque of the rotating member 30. In this embodiment, the load member 70 is a compression spring arrangement, and is not intended to limit the present application. In other embodiments, other elements such as a collar may be used instead.

In this embodiment, the spray head structure 1 further includes a nozzle cover 90. The nozzle cover 90 has a third end 91, a fourth end 92 and a nozzle opening 93. The third end 91 and a fourth end 92 are located on opposite sides of the nozzle cover 90, and the nozzle opening 93 is located on the fourth end 92, and the opening outer diameter W1 of the third end 91 of the nozzle cover 90 is smaller than the fourth end 92 The opening outer diameter W2. The nozzle cover 90 is sleeved on the air outlet end 13 of the airflow pipe 10 with a third end 91, so that the rotating member 30, the spoiler 40 and the load member 70 are located in the nozzle cover 90, and the outlet end 411 of the spoiler 40 Corresponds to the nozzle opening 93. In addition, when the outlet end 411 of the spoiler 40 rotates around the axis P, the maximum rotation diameter of the outlet end 411 is smaller than the diameter of the nozzle port 93, so the outlet end 411 does not interfere with the nozzle port 93, so the spoiler 40 can rotate smoothly. In addition, the nozzle cover 90 can also protect the spoiler tube 40 from being damaged by the impact of the external force.

When the high-velocity gas enters the airflow channel 11 and the spoiler channel 41 in sequence from the inlet end 12 and passes through the liquid outlet end 52 of the liquid flow tube 50 in the spoiler channel 41, the The Venturi effect will occur at the liquid outlet end 52, so that the pressure at the liquid outlet end 52 is smaller than the pressure at the liquid inlet end 51. In this way, due to the influence of the pressure difference between the liquid outlet end 52 and the liquid inlet end 51, the cleaning liquid 2 in the liquid storage tank 60 is sucked from the liquid inlet end 51 to the liquid outlet end 52 and discharged. Next, the cleaning liquid 2 discharged from the liquid discharge end 52 is mixed with the high-flow gas in the spoiler 41 to be atomized, and then ejected from the outlet end 411 with the high-flow gas. Among them, while the cleaning liquid 2 and the high-velocity gas are ejected from the outlet end 411, the outlet end 411 rotates around the axis P, so that the gas-liquid mixed washing water column is continuously sprayed in a swirling shape. Therefore, the spraying area of the spray head structure 1 can be increased to increase the cleaning area by using the washing water column of the swirling spray type. On the other hand, the nozzle cover 90 limits the spray range of the outlet end 411 to prevent the spray range of the cleaning water column from being too large and uncontrolled, thereby affecting the operation of the operator.

In addition, since the load member 70 is mounted on the rotating member 30, the load of the rotating member 30 is increased to increase the torque of the rotating member 30, so that the overall cleaning ability of the shower head structure 1 can be improved. For details, please refer to the following table. The following table shows the sprinkler structure 1 and the sprinkler structure 1 without the load 70 in the present embodiment at the same water volume. Comparison of time. Therefore, it can be known that the nozzle structure 1 of this embodiment has better performance in terms of air volume, rotation speed when there is no boiling water, rotation speed when boiling water, and water consumption time compared with the nozzle structure 1 without the load 70. Therefore, the load member 70 can improve the overall cleaning ability of the shower head structure 1.

The air hood 120 is located in the nozzle cover 90 and has an air duct 1201 and an air outlet 1202 communicating with the air duct 1201. One end of the air hood 120 opposite to the air outlet 1202 is sleeved on the air duct 10. More specifically, one end of the air hood 120 relative to the air outlet 1202 is attached to the assembly 110 to be sleeved on the air duct 10. The coupling pipe body 43, the fan member 100, the rotating member 30 and the load member 70 of the spoiler 40 are located in the air duct 1201 of the air hood 120.

As shown in FIG. 2, in this embodiment, when the rotating member 30 rotates, the fan member 100 is driven to rotate together, so that an airflow passes through the opening 94 and enters the air guide hood 120 from the air inlet 1101 and along the first direction. D1 leaves the air hood 120 through the air duct 1201 and the air outlet 1202. Because the air hood 120 has the effect of collecting wind, the airflow can further enhance the degree of mixing and atomization of the high-velocity gas and the cleaning liquid 2, thereby improving the overall cleaning effect of the nozzle structure 1. In addition, in addition to the effect of collecting wind, the wind deflector 120 can also ensure that the load member 70 does not shake excessively when rotating.

In this embodiment, the airflow generated by the fan member 100 flows from the air inlet 1101 to the air outlet 1202 along the first direction D1, but is not limited thereto.
