[0038] To enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solution in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

These terms are mainly used to better describe this application and its embodiments, and are not used to limit that the indicated device, element or component must have a specific orientation, or be constructed and operated in a specific orientation. And, in addition to being able to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to the specific situation.

[0040] In Embodiment 1 of this embodiment, a steam sprayer is provided, as Figures 1 to 4 shown, which includes a nozzle 1, a combustion housing 3, a burner 32, a medicament 13, an auxiliary agent pipe 14, and a deflector.

[0041] As Figure 1 shown, the burner 32 is installed at one end of the combustion housing 3 for providing a heat source into the combustion housing. At least part of the auxiliary agent pipe 14 is installed in the combustion housing 3, and the heat source can heat the auxiliary agent in the auxiliary agent pipe 14 to turn the auxiliary agent into a high-temperature and high-pressure auxiliary agent mist. A smoke exhaust port is provided on the side wall of the combustion housing for discharging the black smoke generated by fuel combustion in the combustion housing, so as to maintain a good thermal efficiency in the combustion housing.

[0042] Among them, the auxiliary agent pipe 14 and the medicament pipe 13 are connected to the nozzle 1. Specifically, the steam sprayer may include only one nozzle, which is connected to the auxiliary agent pipe 14 and the medicament pipe 13 at the same time; or it may include two nozzles respectively connected to the auxiliary agent pipe 14 and the medicament pipe 13.

[0043] Combined with Figure 1 、 Figure 2As shown, the nozzle 1 is arranged on the outer side of the combustion housing 3 and is used for spraying medicine mist, which is specifically an auxiliary agent mist carrying medicine droplets. The flow guide member is installed near the nozzle 1 and has a flow guide space. The nozzle 1 jets in the flow guide space, and the medicine mist ejected from the nozzle 1 can flow along the inner wall of the flow guide member. The flow guide member is used to guide the flow direction of the medicine mist. It should be noted that "jet flow" means that the fluid jets out from the nozzle, orifice, or slit. The flow guide member can be in the shape of a horn, a cylinder, an eagle's beak, a kettle spout, etc.

[0044] Among them, as Figure 1 , Figure 2 shown, the steam sprayer includes a flow guide ring 2. Both ends of the flow guide ring 2 are through, and it is a ring structure. It is sleeved on the nozzle 1. The port of the nozzle 1 is located inside the flow guide ring 2 and jets along the through direction of the flow guide ring 2. The flow guide ring 2 protrudes from the nozzle 1 along the jet flow direction of the nozzle 1, so that the medicine mist can flow along the inner wall of the flow guide ring 2. The flow guide ring 2 serves as the flow guide member.

[0045] Preferably, the longitudinal section of the flow guide ring 2 is circular to reduce the flow resistance of the mist flow. Optionally, the longitudinal section of the flow guide ring 2 can also be other polygonal structures or flat structures.

[0046] In this way, when the steam sprayer of the present application sprays medicine mist, a pressure difference can be generated between the inner side and the outer side of the flow guide ring 2. The air outside the flow guide ring 2 is sucked into the inner side of the flow guide ring 2, thereby strengthening the air flow of the medicine mist spraying, improving the spraying force of the sprayer, more powerfully pushing the medicine mist, and at the same time, the mist flow is more concentrated, making the operation of the steam sprayer more accurate.

[0047] Specifically, as Figure 1 shown, the flow guide ring 2 and the combustion housing 3 are of a split structure. There is a ventilation gap 5 between the combustion housing 3 and the flow guide ring 2. Air enters the inside of the flow guide ring 2 from the ventilation gap 5. At the same time, enough space is reserved for the auxiliary agent pipe 14 to enter the combustion housing 3. One end of the combustion housing 3 is connected with a cover plate 31. The cover plate 31 and the flow guide ring 2 are also of a split structure, which is convenient for disassembling some auxiliary agent pipes inside the flow guide ring or the combustion housing for maintenance or replacement.

[0048] More specifically, as Figure 3 shown, the combustion housing is connected with an exhaust pipe 34. The outlet end of the exhaust pipe 34 is an exhaust port 33. The exhaust pipe extends upward so that the ventilation gap 5 is staggered from the exhaust port 34, so that the black smoke is as far away from the ventilation gap 5 as possible to prevent the black smoke from entering the flow guide ring 2 and thus affecting the cleanliness of the medicine mist.

[0049] Among them, the flow guide ring 2 is connected to the auxiliary agent pipe 14 or the auxiliary agent nozzle 1 through a connecting member 4. The volume of the connecting member 4 should be as small as possible to reduce the blocking effect on the air. As a specific solution, as Figure 4As shown, the connecting member 4 has a "one" - shaped structure, and an insertion ring 41 is provided in the middle for inserting the auxiliary agent pipe or nozzle. The connecting member 4 can also be a "cross" or "rice" - shaped structure, etc.

[0050] Specifically, the auxiliary agent and the medicament are respectively transported from the auxiliary agent pipe 14 and the medicament pipe 13 and converge inside the diversion ring 2. As an alternative, mounting holes are formed in the side wall of the diversion ring 2 for inserting the medicament pipe 13 or the nozzle 1. As another alternative, a notch is provided at one end of the diversion ring 2 close to the combustion housing for accommodating the medicament pipe 13 or the nozzle 1.

[0051] Preferably, the port of the nozzle 1 is located on the axis of the diversion ring 2 to make the airflow inside the diversion ring 2 as balanced as possible.

[0052] Specifically, the diversion ring 2 protrudes from the nozzle 1 along the jet direction of the nozzle 1. More specifically, the diversion ring 2 protrudes from the nozzle 1 along the jet direction of the nozzle 1 by 15 mm to 50 mm, such as 18 mm, 20 mm, 25 mm, 26 mm, 28 mm, 35 mm, 37 mm or 42 mm, etc. Preferably, the diversion ring 2 protrudes from the nozzle 1 along the jet direction of the nozzle 1 by 15 mm to 35 mm to prevent the diversion ring 2 from being too long and causing excessive interference to the medicine mist.

[0053] Optionally, the inner diameter of the diversion ring 2 is at least 6 times larger than the inner diameter of the port of the nozzle 1 to prevent the diversion ring 2 from causing too much blockage to the nozzle 1 in the radial direction. For example, if the port of the nozzle 1 is 2 mm, the port of the diversion ring 2 is at least 12 mm. Preferably, the inner diameter of the diversion ring 2 is 10 to 15 times the inner diameter of the port of the nozzle 1, so that the radial spraying range of the steam sprayer is wide enough, and at the same time, a good pressure difference is formed between the inner wall of the diversion ring 2 and the outside of the diversion ring 2.

[0054] Optionally, as Figure 5 shown, at least part of the inner wall of the diversion ring 2 is an arc segment, and the arc segment is located in front of the port of the nozzle 1. This arc segment can cause the medicine mist to have an attachment wall effect, so that the medicine mist flows along the arc segment to meet various spraying requirements.

[0055] The nozzle 1 in the related art generally jets in the horizontal direction, with low flexibility. When facing working objects at different heights, the user needs to adjust the arm posture or the rotation angle of the wrist to make the medicine mist spray accurately, and the user is particularly prone to fatigue and even joint damage problems.

[0056] Therefore, preferably, the diversion member has a mating part, and the mating part can be detachably connected to the nozzle 1 or the combustion housing 3. The user can install different types of diversion members at the nozzle 1 of the steam sprayer according to needs, so that the port of the nozzle 1 is located in the diversion space of the diversion member. Specifically, the mating part can be structures such as threads, buckles, etc.

[0057] Specifically, the extension direction of at least part of the inner wall of the flow guide member forms an angle with the jet direction of the nozzle 1 to change the flow direction of the medicine mist.

[0058] As the second implementation manner in this embodiment, on the basis of the first implementation manner, the liquid inlet end of the nozzle 1 is connected to the auxiliary agent pipe 14, and the side wall of the nozzle 1 is connected to the medicine pipe 13 so that the auxiliary agent and the medicine converge in the nozzle 1.

[0059] Specifically, the side wall of the flow guide ring 2 is formed with an installation hole 21, and the medicine pipe 13 is inserted into the installation hole 21. Preferably, the medicine pipe is detachably connected to the nozzle 1. The user can first install the nozzle 1 to the auxiliary agent pipe 14 and then fit the flow guide ring 2 onto the nozzle 1, and then insert the medicine pipe 13 into the nozzle 1 from the installation hole 21 to achieve the transmission of the medicine.

[0060] Among them, the nozzle 1 forms a jet channel, and the middle part of the jet channel contracts to form a pressurizing part, which cooperates with the flow guide ring 2 to further increase the medicine mist spraying force. Specifically, the medicine pipe 13 communicates with the outside of the pressurizing part and is located near the port of the nozzle 1 so that the auxiliary agent converges with the medicine after passing through the pressurizing part. Thus, after passing through the pressurizing part, the flow rate of the auxiliary agent increases, and the pipeline pressure near the port of the nozzle 1 further decreases, sucking the medicine from the medicine pipe 13 into the nozzle 1.

[0061] As the third implementation manner in this embodiment, on the basis of the first implementation manner, as Figure 6 shown, the nozzle is divided into a medicine nozzle 12 and an auxiliary agent nozzle 11. The medicine nozzle 12 is arranged adjacent to the port of the auxiliary agent nozzle 11, and the jet direction of the medicine nozzle 12 intersects with the jet direction of the auxiliary agent nozzle 11. The through direction of the flow guide ring 2 is consistent with the jet direction of the auxiliary agent nozzle 11.

[0062] Among them, the medicine nozzle 12 and the medicine pipe 13 can be of an integral structure, and the auxiliary agent nozzle 11 and the auxiliary agent pipe 14 can be of an integral structure.

[0063] Optionally, the auxiliary agent nozzle 11 extends along the axial direction of the flow guide ring 2, and the medicine nozzle 12 extends along the radial direction of the flow guide ring 2.

[0064] Specifically, the side wall of the flow guide ring 2 is formed with an installation hole 21, and the medicine pipe 13 or the medicine nozzle 12 is inserted into the installation hole 21 and is detachably connected to the nozzle.

[0065] Among them, the auxiliary agent nozzle 11 and the medicine nozzle 12 are detachably connected to the flow guide ring 2. The specific connection method can be plugging, clamping, screw connection, etc. When the user finds that the nozzle is blocked, the nozzle can be removed from the flow guide ring 2, and a cleaning tool such as a brush can be inserted into the channel of the nozzle to clean the nozzle. After cleaning, the nozzle is reinstalled onto the flow guide ring 2.

[0066] In this application, the terms "installed", "set up", "provided with", "connected", "linked", "socketed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral structure; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, or there may be internal communication between two devices, components or parts.
