The specific meaning of these terms in this application will be understood by those of ordinary skill in the art as appropriate.

As shown in fig. 1, the present embodiment relates to a steam atomizer including a combustion tube 100, a cover plate 200, a spiral tube 300, and a fuel chamber 400. The spiral tube 300 is disposed in the cavity of the combustion tube, and the spiral tube 300 conveys medium through the head tube section 310 and the tail tube section 320 at the ends thereof, the tail tube section 320 extends from the outer side of the spiral tube 300 to one end of the head tube section 310, and the tail tube section 320 and the head tube section 310 are both penetrated out from the cover plate. The coil 300 and its end sections 310, 320 together form a heating tube, and the side of the burner tube remote from the cover plate is connected to a fuel chamber 400. The connection between the burner tube 100 and the cover plate 200 is not limited to a plug, a snap connection, a screw connection, or the like.

The head section 310 in this embodiment may be used as either an additive inlet or an additive (vapor-like) outlet; the tail section 320 may serve as either an additive inlet or an additive (vaporous) outlet.

Specifically, the side of the fuel chamber 400 facing the cover plate 200 is provided with a flame spraying port 410, and the flame spraying port 410 is located at the axis of the combustion tube 100, so that the fuel-air mixture can be continuously sprayed to the combustion tube 100, and the fuel-air mixture is used for heating the auxiliary agent in the heating tube 300 after being ignited.

After the auxiliary agent in the heating pipe 300 is heated to form high-temperature steam, the high-temperature steam is converged with the pesticide, and the pesticide drops are wrapped by the high-temperature steam and sprayed on the inner part, so that compared with the traditional scheme that the pesticide and the auxiliary agent are heated together and sprayed, the spraying efficiency of the pesticide is improved, and meanwhile, the pesticide property is guaranteed.

To solve the problem of uneven heating of the auxiliary agent in the heating pipe of the related art, the tail pipe section 320 extends from the outer side of the spiral pipe 300 toward the end of the head pipe section 310, and the tail pipe section 320 extends from the outer side of the spiral pipe 300 toward the end of the head pipe section 310. Therefore, the cavity inside the spiral tube 300 is opposite to the flame spraying opening 410, so that the oil-gas mixture is convenient to form vortex, the fuel is more uniformly filled in the combustion tube, meanwhile, the spiral tube 300 and the tail tube section 320 are staggered from the flame spraying opening 410, the tail tube section 320 is prevented from being continuously burnt, the service life of the spiral tube is prolonged, and the heating tube cannot be subjected to the condition that the pressure in the tube is inconsistent due to too fast local heating, so that the auxiliary agent flows smoothly. In addition, the heating pipe of the present embodiment is easier to be demolded during the manufacturing process than the heating pipe of the related art.

As a specific solution, part of the outer surfaces of the tail pipe section 320 and the head pipe section 310 are attached to the side of the cover plate away from the combustion pipe. More specifically, the tailpipe section 320 and the head pipe section 310 are welded to the cover plate 200 so that a user simultaneously brings the heating pipe out when the cover plate is detached from the burner pipe.

Alternatively, the tailpipe section 320 of the heating pipe 300 is a straight pipe and extends in the direction of the central axis 330 of the spiral pipe 300.

Alternatively, the tailpipe section 320 is a straight or curved pipe, which can accommodate a variety of requirements.

As an alternative scheme, the spiral tube is provided with a plurality of spiral ring bodies, the distance between any two adjacent spiral ring bodies in the direction of the central axis is more than or equal to 10mm, and the radial dimension ratio of the two ends of the spiral tube is 0.3-0.8, so that the auxiliary agent in the heating tube can be heated in all directions. Alternatively, the ratio of radial dimensions of the ends of the spiral tube may be 0.3, 0.4, 0.5, 0.6, 0.7 or 0.8.

Since the fuel pipe is filled with the oil-gas mixture from the nozzle 410 of the fuel chamber 400, a certain process is required, and the combustion tube 100 is continuously burned during the operation of the steam atomizer, the oil-gas mixture is ignited just after entering the combustion tube 100, which results in a larger flame and a higher temperature as the oil-gas mixture approaches the nozzle 410.

As an alternative, as shown in fig. 2, the inner diameters of the spirals 312 of the heating tube 300 in the present embodiment are different, the diameter of the spiral tube 300 is gradually contracted toward the cover plate 200 side in the radial direction, that is, the diameter of the spiral tube 300 is larger as it approaches the flame port 410, and the diameter of the spiral tube 300 is smaller as it approaches the flame port 410, so that the heating tube is heated uniformly, more specifically, the spiral tube 300 is formed with a circular truncated cone-shaped space, and the tail tube section 320 extends along the direction of the generatrix of the circular truncated cone-shaped space or along the direction of the central axis 330 of the spiral tube 300.

Furthermore, the terms "mounted," "configured," "provided," "connected," "coupled," and "sleeved" are to be construed broadly. For example, it may be a fixed connection, a removable connection, or a unitary construction; may be a mechanical connection, or an electrical connection; may be directly connected, or indirectly connected through intervening media, or may be in internal communication between two devices, elements, or components. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be.

The foregoing is merely a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and variations may be made to the present application by those skilled in the art.
