Description

Technical Field

[0001] This utility model relates to the technical field of liquid spraying cleaning devices, and in particular to a gas-liquid mixing cleaning device adapted to sensors. Background Technology

[0002] With the increasing demand for efficient and environmentally friendly cleaning technologies in industry, agriculture, and daily life, water spray heads, as important cleaning tools, directly affect cleaning effectiveness and efficiency. Traditional water spray heads mainly increase spray force and cleaning range by increasing water pressure or changing nozzle structure, but these methods often suffer from high energy consumption, complex structure, and susceptibility to damage. Several technologies for enhancing water spray head performance already exist on the market, mainly including pressurized shower heads and high-pressure water jet cleaning systems. Pressurized shower heads utilize an energy-saving pressurized water inlet device installed at the showerhead tail, using air pressure to force liquid to accelerate its flow, thereby increasing water speed and pressure. However, while this design can increase water pressure to some extent, its structure limits the significant expansion of the cleaning range. High-pressure water jet cleaning systems utilize high-pressure water pumps and nozzles to form high-speed water jets with powerful impact and cutting capabilities, but these systems are complex, costly, and not suitable for all scenarios. Therefore, this application proposes a gas-liquid mixing cleaning device adapted to sensors. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing a gas-liquid mixing cleaning device suitable for sensor cleaning.

[0004] The technical solution of this utility model is as follows: a gas-liquid mixing cleaning device adapted to a sensor, comprising a sensor body and a sensor mounting housing for mounting the sensor body. The top of the sensor mounting housing is also equipped with a nozzle body for cleaning the sensor body. The nozzle body is provided with a liquid inlet connector and a gas inlet connector. The output end of the liquid inlet connector is provided with a liquid channel opened in the nozzle body. The output end of the liquid channel is provided with a nozzle located in the nozzle body. A spray hole is provided below the nozzle.

[0005] The output end of the air inlet connector is also provided with an air inlet channel opened in the nozzle body. The output end of the air inlet channel is provided with an air port located on one side of the liquid spraying hole. The airflow ejected from the air port changes the coverage area of ​​the liquid sprayed from the liquid spraying hole on the sensor body.

[0006] Optionally, the air inlet is located on one side of the liquid spray hole and is connected to it through a micro-through hole.

[0007] Optionally, both the liquid inlet and the air inlet are equipped with a control mechanism, which includes a liquid volume regulating valve and an air flow control valve.

[0008] Optionally, both the air inlet connector and the liquid inlet connector are equipped with a cleaning execution component for cleaning and sealing their internal cavities;

[0009] The cleaning execution component includes a rotating connecting plate that is threadedly rotatably connected to the inner cavity of the air inlet connector and the liquid inlet connector, and a fixed disc is connected to one end of the rotating connecting plate for cleaning its inner cavity.

[0010] Optionally, the fixed disk has a disc-shaped structure, and the outer ring array of the fixed disk is provided with multiple cleaning brushes.

[0011] Optionally, a connecting post for fixing the fixed disk and the rotating connecting disk is provided between the two, and a pinch block is also fixedly connected to the end of the rotating connecting disk away from the fixed disk.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This invention utilizes a liquid inlet connector and an air inlet connector to allow air to be drawn in through the air inlet channel and mixed with the gas through a small through-hole while the liquid is flowing. Due to the presence of air, the mixed liquid forms bubbles when it is sprayed out. These bubbles expand rapidly under high pressure and burst, producing a micro-explosion effect, thereby enhancing the impact force and diffusion range of the liquid. At the same time, the addition of bubbles also reduces the continuity of the liquid, making it easier for the liquid to form a water mist or water ring after being sprayed out, further expanding the cleaning range.

[0014] This utility model also uses the cleaning execution component to rotate and clean the inner cavity of the liquid inlet or air inlet. For the air channel, cleaning allows for gas flow. The cleaning execution component in the liquid inlet prevents the cleaning liquid from clogging the inner cavity and seals the liquid inlet or air inlet when not in use, ensuring the smooth operation of the channel inside the nozzle body.

[0015] The sensor body in this utility model can also be replaced with components such as radar, or the overall structure of the nozzle body can be replaced for cleaning of industrial equipment and agricultural irrigation, etc.

[0016] In summary, this invention significantly expands the cleaning range of the liquid by adding an air passage and utilizing the micro-explosion effect, improves cleaning efficiency, increases the sprayed liquid pressure for more thorough cleaning, precisely controls the liquid volume and air flow, and uses the airflow size to change the spray coverage area, thereby enhancing the cleaning effect, reducing waste of cleaning resources and energy consumption, and is simple in structure and easy to maintain.

[0033] Example

[0034] like Figure 1 , Figure 3 and Figure 4 As shown, this utility model proposes a gas-liquid mixing cleaning device adapted to sensors, including a sensor body 6 and a sensor mounting housing 4 for mounting the sensor body 6. A nozzle body 1 for cleaning the sensor body 6 is also mounted on the top of the sensor mounting housing 4. The nozzle body 1 is made of corrosion-resistant and high-strength material. The nozzle body 1 is respectively provided with a liquid inlet connector 2 and an air inlet connector 3. Both the liquid inlet connector 2 and the air inlet connector 3 are provided with control mechanisms, including a liquid flow regulating valve and an air flow control valve. Users can adjust the liquid flow and air flow according to actual needs to achieve optimal performance. Cleaning effect: Both the air inlet connector 3 and the liquid inlet connector 2 are equipped with a cleaning execution component 5 for cleaning and sealing their internal cavities. The cleaning execution component 5 includes a rotating connecting disk 54 that is threadedly rotatably connected to the internal cavities of the air inlet connector 3 and the liquid inlet connector 2. One end of the rotating connecting disk 54 is connected to a fixed disk 52 for cleaning its internal cavity. The fixed disk 52 has a disc-shaped structure, and multiple cleaning brushes 53 are arranged in an array on the outer ring of the fixed disk 52. A connecting post 51 for fixing the fixed disk 52 and the rotating connecting disk 54 is provided between the fixed disk 52 and the rotating connecting disk 54. A pinch block 55 is also fixedly connected to the end of the rotating connecting disk 54 away from the fixed disk 52.

[0035] Reference Figure 2As shown, the output end of the liquid inlet connector 2 is provided with a liquid channel 21 opened within the nozzle body 1. The output end of the liquid channel 21 is provided with a nozzle 22 located within the nozzle body 1. Below the nozzle 22 is a spray hole 23. The arrangement of the spray holes 23 can be adjusted according to specific needs to achieve different spray patterns and cleaning ranges. The nozzle body 1 in this invention has a compact structure and reasonable design, facilitating installation and maintenance. Furthermore, the reduced number of complex mechanical parts also lowers the failure rate. The output end of the air inlet connector 3 is also provided with an air inlet channel 31 opened within the nozzle body 1. The output end of the air inlet channel 31 is... An air inlet 32 ​​is provided on one side of the liquid spray hole 23. The air inlet 32 ​​is located on one side of the liquid spray hole 23 and is connected to it through a small through hole. It is used to mix the liquid with air. When the mixed liquid is sprayed out, it forms bubbles. These bubbles expand rapidly under high pressure and burst, producing a micro-explosion effect, thereby enhancing the impact force and diffusion range of the liquid. The mixing of air and liquid reduces the density of the mixed fluid, thereby producing a higher spray speed and pressure under the same pressure. At the same time, the addition of bubbles also reduces the continuity of the liquid, making it easier for the liquid to form water mist or water ring after spraying out, further expanding the cleaning range.

[0036] In this embodiment, the nozzle body 1 is used for cleaning the sensor. Specifically, the cleaning execution component 5 is rotated out of the liquid inlet connector 2 and the air inlet connector 3. While rotating the pinch block 55, the connecting plate 54, the connecting column 51 and the fixed disc 52 rotate synchronously. Therefore, the cleaning brush 53 will rotate and clean the inner wall of the liquid inlet connector 2 or the air inlet connector 3. After opening the liquid inlet connector 2 and the air inlet connector 3, the water pump and the air pump are connected to the liquid inlet connector 2 and the air inlet connector 3 respectively. The liquid enters the nozzle 22 through the liquid channel 21. At the same time, the air is drawn into the tiny through hole through the air inlet channel 31 and enters the nozzle 22 and mixes with the liquid. Due to the presence of air, the mixed liquid forms bubbles when it is sprayed out. These bubbles expand rapidly under high pressure and burst, producing a micro-explosion effect. They are sprayed out through the spray hole 23 to form an air curtain, thereby enhancing the impact force and diffusion range of the liquid. The nozzle body 1 in this solution can also change the number and angle of the nozzles 22 according to the usage scenario, so as to realize different spraying modes and cleaning ranges.

[0037] This embodiment opens the jet channel while spraying the liquid, and increases the coverage area and improves the cleaning effect by adjusting the airflow size and changing the spray angle. Opening the jet channel while spraying the liquid allows the airflow to be mixed with the liquid flow through the micro-channel and the main jet nozzle, thus enhancing the cleaning effect.

[0038] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
