[0002] Atomizing nozzles and road maintenance vehicles are equipment related to road maintenance and upkeep, playing an important role in the maintenance of urban infrastructure and helping to improve road safety and service life.

[0003] According to the publication (announcement) number CN110241768A, published (announcement) date 2019-09-17, a water sprinkler truck with an easy-to-adjust water spraying mode is disclosed, including a vehicle body, a water tank, a bracket, a water pump, a bottom spray assembly, a side spray assembly, and a top spray assembly. The water tank is fixedly mounted on the vehicle body, and a bracket is fixedly mounted at the rear end of the vehicle body. A water pump is fixedly mounted on the bracket, and the inlet end of the water pump is connected to the water tank pipeline. A bottom spray assembly is fixedly mounted at the lower end of the bracket, a side spray assembly is fixedly mounted on the side of the bracket, and a top spray assembly is fixedly mounted at the upper end of the bracket. The bottom spray assembly, side spray assembly, and top spray assembly are all connected to the outlet end pipeline of the water pump.

[0004] However, in the prior art, including the aforementioned patent, the spraying location is changed by operating different spraying components and connecting them to the water pump. In order to meet the spraying effect, different specifications of nozzles need to be installed, which makes it very troublesome for users to not only change the water pump, but also change the nozzles.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-5 As shown, an atomizing nozzle and a road maintenance vehicle include a base 2 and a vehicle body 1, with the base 2 arranged in a linear array on the vehicle body 1;

[0026] Multiple nozzle paddles 4 are arranged in a circular array on the base 2, and an elastic membrane 42 is provided between adjacent nozzle paddles 4. The nozzle paddles 4 and the elastic membrane 42 surround to form a nozzle.

[0027] The limiting member 3 is slidably set on the base 2, and it is used to adjust the opening of the nozzle pawl 4;

[0028] The impact plate 31, which moves axially at the nozzle outlet, blocks the outlet when the nozzle deflector 4 is at its lowest opening.

[0029] Specifically, the base 2 is provided with a telescopic rod 21 for controlling the sliding of the limiting member 3. The contact surface between the limiting member 3 and the nozzle tweezers 4 is an inclined surface, and the nozzle tweezers 4 have a notch. The nozzle tweezers 4 are bent along the notch by the limiting member 3, so that multiple nozzle tweezers 4 bend synchronously, and the bending amplitude varies with the sliding distance of the limiting member 3. The nozzle tweezers 4 have a groove 41 for the limiting member 3 to slide. As the limiting member 3 moves closer to the base 2, the bending amplitude of the nozzle tweezers 4 increases, so that the spraying range of the nozzle formed by the nozzle tweezers 4 is adjustable. The expansion of the elastic membrane 42 can prevent liquid leakage from the nozzle, and the impact plate 31 is always moving on the axis of the nozzle, so that the sprayed liquid is atomized at the impact plate 31. The smaller the opening between the nozzle tweezers 4, the smaller it is than the diameter of the impact plate 31. Stop the liquid supply and drive the limiting member 3 to the limit distance close to the base 2. At this time, the impact piece 31 completely blocks the nozzle formed by the nozzle lever 4, which plays a role in preventing dripping.

[0030] Furthermore, the telescopic rod 21 can be an electric telescopic rod, a hydraulic rod, or other drive structures known to those skilled in the art. The impact plate 31 is connected to the limiting member 3 via the fixing rod 32, ensuring that the impact plate 31 and the limiting member 3 move synchronously. A pointed cone 33 is also fixedly provided on the impact plate 31, and through holes 34 are provided on the impact plate 31 and the pointed cone 33. When the opening of the nozzle lever 4 is large, the angle of the liquid flow is large, and it will directly impact the impact plate 31 to atomize. When the opening of the nozzle lever 4 is reduced, the angle of the liquid flow decreases and the distance between it and the impact plate 31 is shortened. The liquid flow will first impact the pointed cone 33 and then flow along the through hole 34 to the impact plate 31. When the opening of the nozzle lever 4 is at its smallest, the impact plate 31 completely blocks the nozzle opening. At this time, the side hole of the through hole 34 is offset from the nozzle opening to prevent droplets from leaking through the through hole 34.

[0031] In the above technology, the nozzle lever 4 is bent by the lower edge notch pressed against the limiting member 3, thereby causing multiple nozzle levers 4 to bend synchronously, and the bending amplitude varies with the sliding distance of the limiting member 3, making the spraying range of the nozzle formed by the nozzle levers 4 adjustable. Moreover, after the liquid supply stops, the impact piece 31 completely seals the nozzle formed by the nozzle levers 4, playing a role in preventing dripping.

[0032] As a further embodiment of this utility model, it also includes a fixing seat 6 fixedly disposed on the base 2, and the port of the fixing seat 6 is provided with an infusion chamber 5, and a piston 51 for sealing is disposed in the infusion chamber 5.

[0033] Specifically, the piston 51 is provided with an elastic element 52 that pushes the piston 51 toward the liquid inlet direction. When the liquid inlet pressure is sufficient, the hydraulic pressure overcomes the elastic force of the elastic element 52 and creates a gap between the piston 51 and the inlet chamber 5. The liquid enters the inlet chamber 5 through this gap and is sprayed through the nozzle formed by the nozzle flap 4.

[0034] As a further embodiment of this utility model, it also includes an air delivery channel 61 opened in the fixed base 6 and used to guide gas to push the piston 51, and the fixed base 6 is provided with a plurality of liquid delivery channels 62 pointing to the liquid delivery chamber 5.

[0035] Specifically, the end of the gas delivery channel 61 pointing towards the infusion chamber 5 is a narrow opening, which makes the inner diameter of the gas delivery channel 61 decrease along the gas delivery direction, thus concentrating the airflow and further increasing the gas pressure. The infusion channels 62 are all facing the narrow opening of the gas delivery channel 61. When the high-speed airflow passes through the narrow opening, it generates low pressure due to the speed difference. This low pressure will actively draw the liquid in the infusion channel 62 into the infusion chamber 5 for mixing.

[0036] As another embodiment of the present invention, the end of the elastic membrane 42 is provided with an arc-shaped portion 43, and the arc-shaped portion 43 has a bulging state when the nozzle tweezers 4 are at their lowest opening.

[0037] Specifically, the structure of the arc-shaped portion 43 is as follows: Figure 4 As shown. When the opening of two adjacent nozzle flaps 4 is at its maximum, the time interval is at its maximum, and the elastic membrane 42 is completely flat. When the opening of adjacent nozzle flaps 4 is at its minimum, the time interval is at its minimum. Both sides of the elastic membrane 42 are subjected to the pressure of the nozzle flaps 4, causing the elastic membrane 42 to bulge into an O-shape and the two sides to stick tightly to each other. The inside of the elastic membrane 42 is tubular, and the inner diameter of the tubular structure decreases along the liquid outlet direction of the nozzle. When a droplet is suspended at the end of the nozzle flap 4, the droplet will contact the arc-shaped part 43. Due to the capillary effect of the tubular structure formed by the elastic membrane 42 on the droplet, the droplet enters the elastic membrane 42 under the action of surface tension, which further plays a role in preventing dripping.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
