The atomizer 100 according to the embodiment of the present application will be described below with reference to FIGS. 1 to 11. The atomizer 100 can be used for movable vehicles 200 such as unmanned aerial vehicles, unmanned vehicles, and unmanned ships. It should be noted that the vehicle 200 is a collective term for vehicles. For example, cars, motorcycles, etc. are collectively referred to as ground vehicles 200. Airplanes, helicopters, etc. are collectively referred to as flying vehicle 200, also known as aircraft. Vessels are collectively referred to as marine vehicles 200. The three are collectively referred to as "vehicle 200". For example, in FIG. 11, the vehicle 200 is an unmanned vehicle.

As shown in FIG. 1 and FIG. 2, the atomizer 100 according to the embodiment of the present application includes: a housing assembly 20, a mist making device 10 and a blowing device 30.

Specifically, as shown in Figure 1, Figure 2 and Figure 5, at least a part of the housing assembly 20 is used to guide the air flow, the housing assembly 20 is provided with a first installation cavity 52, and the housing assembly 20 is provided with a first mounting cavity 52. The fluid inlet 5611 and the fluid outlet 71 communicated with the installation cavity 52. In other words, the fluid inlet 5611 and the fluid outlet 71 are in communication through the first mounting cavity 52. The air flow can flow into the first installation cavity 52 through the fluid inlet 5611 and then flow out of the atomizer 100 through the fluid outlet 71.

As shown in FIG. 2, the mist-making device 10 is used to produce and spray mist droplets. A part of the mist-making device 10 is provided in the first mounting cavity 52 and the other part extends toward the fluid outlet 71. The air blowing device 30 is arranged in the first installation cavity 52, and the air blowing device 30 is located upstream of the mist making device 10 in the flow direction of the air flow. It can be understood that, in the direction of the air flow, the mist outlet 141 of the mist making device 10 is more reasonably arranged close to the fluid outlet 71, which is beneficial to the atomizer 100 to spray mist droplets, thereby ensuring the working efficiency of the atomizer 100.

It can be seen from this that the atomizer 100 can use the atomizer 10 to produce mist, and the mist droplets emitted by the atomizer 10 can be ejected from the atomizer 100 through the fluid outlet 71. The arrangement of the housing assembly 20 can protect the mist making device 10 to a certain extent, thereby ensuring the reliability of spraying droplets of the atomizer 100 to a certain extent, and improving the reliability of the atomizer 100. At the same time, it can be known that the atomizer 100 of the embodiment of the present application has a simple structure and is easy to assemble.

Due to the structural arrangement of the air blowing device 30 and the mist making device 10, when the atomizer 100 is working, the air blowing device 30 can send the air flow from the fluid inlet 5611 into the first mounting cavity 52 to the fluid outlet 71, which can be The flow velocity of the airflow in the first installation cavity 52 is increased to a certain extent. The housing assembly 20 can also guide the airflow in the first installation cavity 52 to the fluid outlet 71, thereby helping to increase the flow rate of the airflow and the gas pressure in the housing assembly 20. It can be seen that the mist droplets sprayed by the mist making device 10 can be sprayed farther under the action of the high-pressure and high-speed airflow, thereby increasing the range of the atomizer 100 and improving the working efficiency of the atomizer 100 .

According to the atomizer 100 of the embodiment of the present application, a part of the mist making device 10 is arranged in the first installation cavity 52, the other part is extended toward the fluid outlet 71, and the air blowing device 30 is arranged in the first installation cavity 52, In the flow direction of the airflow, the air blowing device 30 is located upstream of the mist making device 10. Therefore, the range of the atomizer 100 can be increased, and the working efficiency of the atomizer 100 can be improved. At the same time, the structure of the atomizer 100 is simple and easy to assemble.

As shown in FIGS. 3 and 8, according to some embodiments of the present application, the mist making device 10 includes: a housing 1, a power assembly 2 and an atomization assembly 3. Wherein, the housing 1 is provided with an air inlet 151 and a mist outlet 141, and the mist outlet 141 is arranged opposite to the fluid outlet 71. The power assembly 2 is arranged in the housing 1, and the power assembly 2 includes a fan 21 and an electric control board 22, and the electric control board 22 is connected with the fan 21 to control the running state of the fan 21. The atomization assembly 3 is arranged in the housing 1. The atomization assembly 3 includes a nozzle 31 and a liquid guide tube 32. The liquid inlet 3111 of the nozzle 31 is connected to the liquid guide tube 32, and the liquid outlet 3112 of the nozzle 31 and the mist outlet 141 are connected. Relative settings.

It can be seen that when the mist making device 10 is operating, the atomizer 100 can control the rotation of the fan 21 through the electronic control board 22, so that the airflow can enter the housing 1 through the air inlet 151, and finally flow to the mist outlet 141 . The liquid guide tube 32 can guide the liquid to be atomized to the nozzle 31 and spray it from the nozzle 31 to the mist outlet 141. At this time, because the gas pressure in the casing 1 is stronger than the gas pressure outside the casing 1, the nozzle 31 sprays The spray is refined and atomized under the action of the high-speed flow of the airflow, and is finally sprayed out of the housing 1 through the mist outlet 141. In turn, the process of mist making and spraying mist droplets of the mist making device 10 is realized. It can be understood that the fan 21 is provided in the mist making device 10, so that the fan 21 can cooperate with the air blowing device 30, which can not only atomize the liquid, but also make the atomized droplets spray a long distance. This is beneficial to reduce the energy consumption of the air supply device 30 and the fan 21 and extend the service life.

As shown in Figures 3 and 4, in some embodiments of the present application, the mist making device 10 further includes a spacer 4, which is provided in the housing 1 and connected to the housing 1 to connect the inside of the housing 1. It is divided into a first working chamber 161 and a second working chamber 162. The first working chamber 161 is in communication with the air inlet 151, the second working chamber 162 is in communication with the mist outlet 141, and the power assembly 2 is located in the first working chamber 161. The chemical assembly 3 is located in the second working cavity 162, the spacer 4 is provided with a vent 41, and the first working cavity 161 and the second working cavity 162 are in communication through the vent 41.

It can be seen from this that in the atomizer 100 of the embodiment of the present application, the spacer 4 can effectively prevent the spray from returning to the housing 1 and contacting the electronic control board 22 to cause a short circuit and other failures. To a certain extent, the reliability of the operation of the power assembly 2 is improved, the reliability of the operation of the mist making device 10 is improved, and the reliability of the operation of the atomizer 100 is ensured.

It is understandable that the spray returned to the housing 1 cannot flow to the first working chamber 161 through the vent 41 and contact the electronic control board 22, because when the fan 21 in the first working chamber 161 rotates, the air flows through the inlet The gas port 151 enters the first working chamber 161, so that the gas pressure in the first working chamber 161 is significantly greater than the gas pressure in the second working chamber 162, so that under the action of the pressure difference, the air flow is caused by the first working chamber. 161 flows to the second working chamber 162, so that the air flow can directly blow away the spray flowing to the vent 41. In this way, the spray isolation effect of the spacer 4 can be ensured, and the reliability of the operation of the mist making device 10 can be ensured, thereby ensuring the reliability of the operation of the atomizer 100.

As shown in FIGS. 3 and 4, in some embodiments of the present application, a part of the spacer 4 is recessed in a direction away from the mist outlet 141 to form a water receiving portion 42. From this, it can be seen that the water receiving part 42 can collect the liquid liquefied from the isolated spray to a certain extent on the water receiving part 42, so as to further improve the spray isolation effect of the spacer 4, and further prevent the spray from returning to the housing. The failure phenomenon such as a short circuit occurs after contact with the electric control board 22 inside 1, which improves the reliability of the operation of the power assembly 2 and the reliability of the operation of the fog making device 10. At the same time, it is also beneficial to improve the structural strength of the spacer 4 and the reliability of the spacer 4. In turn, the reliability of the operation of the atomizer 100 is ensured.

It can be seen that the arrangement of the first reinforcing rib 421 can further improve the structural strength of the spacer 4 and improve the reliability of the spacer 4. In addition, the plurality of water receiving grooves 422 can improve the ability of the water receiving portion 42 to collect liquid, thereby further improving the reliability of the mist making device 10 and the reliability of the atomizer 100.

Specifically, as shown in FIG. 4, the first reinforcement ribs 421 are multiple and are provided on the inner wall of the water receiving portion 42 at intervals. Therefore, the reliability of the spacer 4 can be further improved, and more water receiving grooves 422 are formed on the water receiving portion 42, thereby improving the reliability of the mist making device 10. Optionally, each of the first reinforcing ribs 421 is formed in a plate shape, and the central axis of the plurality of first reinforcing ribs 421 and the central axis of the water receiving portion 42 intersect at the same point. Optionally, an annular rib 423 is further provided on the inner wall of the water receiving portion 42, the central axis of the annular rib 423 coincides with the central axis of the water receiving portion 42, and the annular rib 423 intersects with a plurality of first reinforcing ribs 421. There may be a plurality of annular ribs 423, and the plurality of annular ribs 423 are sequentially spaced and distributed along the extending direction of the first reinforcing rib 421. As a result, the structural strength of the spacer 4 can be further improved, the reliability of the spacer 4 can be improved, and the reliability of the mist making device 10 can be improved.

In some embodiments of the present application, in the flow direction of the airflow, the air vent 41 and the mist outlet 141 are arranged in a staggered manner. As a result, the installation effect of the partition 4 can be further improved, which is beneficial to avoid the influence of the spray returning into the housing 1 on the air flow, so that the gas flows more smoothly near the air vent 41, which is beneficial to make the air flow from the mist outlet 141 The sprayed mist droplets are more refined, which is beneficial to enhance the mist-making effect of the mist-making device 10.

As shown in FIG. 4, in some embodiments of the present application, the vent 41 is located at the edge of the spacer 4 and extends along the circumferential direction of the spacer 4. It is known that the fan 21 in the power assembly 2 is an axial fan 21, and the pressure of the air flow is the largest near the inner peripheral wall of the casing 1, so that the position of the air vent 41 is set, which is beneficial to increase the gas flow speed in the mist making device 10 This further helps to make the mist droplets sprayed from the mist outlet 141 more refined and enhance the mist-making effect of the mist-making device 10.

As shown in FIG. 4, in some embodiments of the present application, the vents 41 are multiple and are distributed along the circumferential direction of the spacer 4. Therefore, the arrangement of a plurality of vents 41 is beneficial to increase the flow area of the gas when flowing through the partition 4, thereby helping to increase the flow velocity of the gas in the mist making device 10, so that the mist sprayed from the mist outlet 141 The droplets are more refined, and the fog-making effect of the fog-making device 10 is enhanced.

As shown in FIG. 4, in some embodiments of the present application, a second reinforcing rib 43 is provided between two adjacent vents 41. Therefore, the structural strength of the spacer 4 can be further enhanced, the reliability of the spacer 4 can be improved, and the reliability of the mist making device 10 can be improved.

In some embodiments of the present application, the spacer 4 and the housing 1 are integrally formed. Therefore, the production efficiency of the mist making device 10 can be improved, and the structural reliability of the mist making device 10 can be improved.

As shown in FIG. 4, in some embodiments of the present application, a part of the outer peripheral wall of the spacer 4 and a part of the inner peripheral wall of the housing 1 jointly define a vent 41. From this, it can be seen that the setting method of the vent 41 is simple and reliable. At the same time, the production and processing of the housing 1 and the spacer 4 are facilitated.

According to some embodiments of the present application, the mist-making device 10 includes a centrifugal nozzle, and the centrifugal nozzle is arranged close to the fluid outlet 71. It can be seen that the mist produced in the mist making device 10 can be sprayed out of the mist making device 10 through a centrifugal nozzle, and the sprayed mist droplets are sprayed out of the fluid outlet 71 under the action of the air flow guided by the wind deflector 7.

According to some embodiments of the present application, the mist-making device 10 includes a pressure spray head, and the pressure spray head is arranged close to the fluid outlet 71.

It can be seen that the structure of the housing assembly 20 is simple, which facilitates the installation and disassembly of the mist making device 10. When the atomizer 100 is working, the air blowing device 30 can send the air flow from the fluid inlet 5611 into the first installation cavity 52 to the fluid outlet 71 on the air guiding shell 7, and the air guiding shell 7 can transfer the air flow into the first installation cavity 52 The airflow is guided to the fluid outlet 71, which is beneficial to increase the flow velocity of the airflow and the gas pressure in the air guiding shell 7. It can be seen that the mist droplets sprayed by the mist making device 10 can be sprayed farther under the action of the high-pressure and high-speed airflow, thereby increasing the range of the atomizer 100 and improving the working efficiency of the atomizer 100 .
