Description

Technical Field

[0001] The utility model relates to the technical field of steam type sprayers, and more specifically to a steam type sprayer and a medicine delivery structure thereof. Background Art

[0002] A sprayer refers to agricultural and forestry plant protection machinery and equipment, which is widely used in pest control, disinfection or fertilization. The steam sprayer separates the agent and the auxiliary agent and heats the auxiliary agent separately, and then mixes the agent at room temperature with the auxiliary agent heated at high temperature and sprays it to ensure the medicinal properties of the agent. It has the advantages of small size and light weight.

[0003] For example, Chinese patent document (CN 219125197 U) provides a steam sprayer, including a burner shell, an end shell, an air supply mechanism and a medicine box, an inner coil is provided in the burner shell, the end shell is provided at one end of the burner shell, a burner and an end cover are provided at both ends of the end shell, and a fireproof chamber is formed in the end shell in the area between the burner and the end cover; the air supply mechanism is used to supply air into the fireproof chamber; an exhaust pipe structure is provided on the burner shell, and the exhaust pipe structure is made of metal; the outlets of the medicine box and the inner coil are connected to the nozzle.

[0004] The above device reduces the impact of high-temperature auxiliary agents on the reagents to a certain extent. However, its coil section (part of the auxiliary agent pipe) is connected to the nozzle, and the reagent pipe is also connected to the nozzle. Although the auxiliary agent and the reagent can be converged inside the nozzle and then ejected uniformly from the nozzle, and the carrying rate of the auxiliary agent to the reagent reaches 100%, the medicinal properties are still seriously damaged because the reagent contacts the high-temperature auxiliary agent inside the nozzle.

[0005] Therefore, as an improvement measure to the prior art, the auxiliary agent and the medicine can be delivered by spraying separately. The characteristic of this structure is that a steam sprayer includes two nozzles, namely an auxiliary agent nozzle and a medicine nozzle. The two nozzles have relative jets. This structure can effectively reduce the influence of the auxiliary agent temperature on the medicine property of the medicine. However, since the medicine and the auxiliary agent will only fuse on the outside of the nozzle, the carrying rate of the auxiliary agent to the medicine is significantly reduced. In the subsequent operation of the sprayer, part of the medicine drips directly from the medicine nozzle and cannot fuse with the auxiliary agent, thereby causing problems such as medicine waste and crop burns.

[0006] For the above problems, the related technologies do not provide effective solutions. Utility Model Content

[0007] In order to solve the problems that may exist in the related technology, some embodiments of the present application provide a medicine delivery structure of a steam sprayer, including: an auxiliary agent nozzle, which is connected to an auxiliary agent tube and can spray an auxiliary agent; a medicine nozzle, which is connected to the medicine tube and is used to deliver the medicine, and the medicine nozzle is arranged adjacent to the port of the auxiliary agent nozzle, and the jet direction of the medicine nozzle intersects with the jet direction of the auxiliary agent nozzle; wherein the port of the medicine nozzle is flat-mouthed, which can make the jet range of the medicine nozzle within the jet range of the auxiliary agent nozzle.

[0008] Furthermore, the port of the auxiliary agent nozzle is circular, and the inner wall of the port has an oblique angle structure so that the auxiliary agent nozzle opens outward.

[0009] Furthermore, the port of the medicine nozzle is oval and of an integrated structure, and the medicine nozzle is divided into two parts, the part close to the medicine nozzle port is a flat tube, and the part far from the medicine nozzle port is a round tube.

[0010] Furthermore, the ratio of the short diameter to the long diameter of the medicine port is less than one half.

[0011] Furthermore, the longitudinal section circumference of the inner wall of the medicine nozzle is at least 3 mm to 13 mm.

[0012] Furthermore, the axis of the agent nozzle and the axis of the auxiliary agent nozzle are perpendicular to each other in the horizontal direction, and the angle between the short diameter of the agent nozzle port and the plumb line is 0° to 4°.

[0013] Furthermore, the distance between the center line of the medicine nozzle and the center line of the auxiliary agent nozzle is 0 mm to 1.2 mm.

[0014] Furthermore, the medicine nozzle is detachably connected to the medicine tube.

[0015] Furthermore, the medicine nozzle is inserted into the medicine tube, and a fastener is arranged on the outside of the medicine tube for clamping the matching part of the medicine tube and the medicine nozzle to fix the relative position of the two.

[0016] Furthermore, the shape of the port of the medicine nozzle is adjustable.

[0017] To achieve the above objectives, the present application also provides a steam sprayer, comprising a medicine delivery structure of any steam sprayer in the above solutions.

[0018] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0019] After the additive is sprayed and can intersect with the pesticide, the additive mist can completely wrap the pesticide and spray it onto the work object to prevent waste. It also further avoids the problem of crop burns caused by dripping of high-concentration pesticides. At the same time, some misalignment space is reserved during the assembly process.

[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0033] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0034] In the present application, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These terms are mainly intended to better describe the present application and its embodiments, and are not intended to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation. Moreover, in addition to being used to indicate orientation or positional relationships, some of the above terms may also be used to express other meanings. For example, the term "upper" may also be used to indicate a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present application can be understood according to the specific circumstances.

[0035] like Figure 1 As shown, the present application provides a steam sprayer, including a medicine delivery structure. The medicine delivery structure includes an auxiliary agent nozzle 1 and a medicine nozzle 2. The auxiliary agent nozzle 1 is connected to the auxiliary agent tube, and the auxiliary agent nozzle 1 can spray the auxiliary agent; the medicine nozzle 2 is connected to the medicine tube and is used to transport the medicine. The medicine nozzle 2 is arranged adjacent to the port of the auxiliary agent nozzle 1, and the jet direction of the medicine nozzle 2 intersects with the jet direction of the auxiliary agent nozzle 1. Specifically, the steam sprayer also includes a burner and a combustion shell. The burner is installed at one end of the combustion shell and is used to provide a heat source into the combustion shell. The auxiliary agent tube is at least partially installed in the combustion shell. The heat source can heat the auxiliary agent in the auxiliary agent tube to turn the auxiliary agent into a high-temperature and high-pressure auxiliary agent mist.

[0036] As another comparison scheme, in order to make the auxiliary agent fully carry the medicine, the port of the auxiliary agent nozzle 1 and the port of the medicine nozzle 2 are of equal diameter, and the center lines of the two are aligned, so that the ejected liquid medium can fully intersect and merge. However, although the auxiliary agent is already in a mist form in the auxiliary agent tube, it is difficult to directly diffuse when it is ejected from the port due to pressure reasons. The auxiliary agent mist coverage area of ​​the auxiliary agent nozzle 1 at the port is almost equal to the size of the auxiliary agent nozzle port, and due to assembly process factors, the matching accuracy of the medicine nozzle and the auxiliary agent nozzle is difficult to meet the above requirements. If this comparison scheme is adopted, the effect is difficult to achieve the expected effect.

[0037] As another comparison scheme, there is no restriction on the port of the agent nozzle 2, and the port 1 of the agent nozzle 2 is placed at the place where the auxiliary agent is diffused (where the coverage range of the auxiliary agent is large enough), so that the agent nozzle 2 is not adjacent to the auxiliary agent nozzle 1 and is far apart. Although this structure can make the spray range of the auxiliary agent cover the medicine, the other parts that are not in contact with the medicine after the auxiliary agent is diffused cannot be fused with the medicine, and it is easy for the auxiliary agent mist to carry only a small amount of drug droplets on one side, affecting the operating effect of the steam sprayer.

[0038] In the drug delivery structure of the steam sprayer of the present application, the port of the drug nozzle 2 is flat-mouthed, so that the jet range of the drug nozzle 2 is within the jet range of the auxiliary agent nozzle. It is worth noting that the flat-mouthed shape here specifically means that the port of the drug nozzle 2 is smaller in a certain direction and relatively larger in a dimension perpendicular to the above direction.

[0039] Since the auxiliary agent sprayed by the auxiliary agent nozzle 1 has a certain pressure, it can have a certain width in the jet direction after leaving the auxiliary agent nozzle 1, so the size of the port of the agent nozzle 2 in the jet direction of the auxiliary agent nozzle may not be limited.

[0040] In this way, the additive can fully intersect with the pesticide after being sprayed, and the additive mist can completely wrap the pesticide and spray it onto the work object to prevent waste. It also further avoids the problem of crop burns caused by dripping of high-concentration pesticides. At the same time, some misalignment space is reserved during the assembly process.

[0041] It is worth noting that the "port" in this embodiment is the last flow position of the agent or auxiliary agent before it leaves the nozzle.

[0042] For the convenience of description, the port of the auxiliary agent nozzle 1 is the first port 11 , and the port for spraying the agent is the second port 21 .

[0043] As a comparative solution, the first port 11 and the second port 21 are both circular, and the diameter of the second port 21 is limited to be smaller than the diameter of the first port 11. Although this solution can also solve the fusion problem of pharmaceutical additives, which will reduce the spraying amount of the second port 21, it results in the drug concentration in the unit additive mist being too low, which is difficult to meet work requirements.

[0044] Specifically, refer to Figures 2 to 5 , the axis of the agent nozzle 2 and the axis of the auxiliary agent nozzle 1 are perpendicular to each other in the horizontal direction, the second port 21 is elliptical, and the ratio of the short diameter to the long diameter is less than one-half. In the process of assembling the agent nozzle 2, the short diameter is made as parallel to the plumb line as possible. Compared with the circular second port 21, the short diameter of the second port 21 is compressed and the long diameter is extended to ensure the injection amount of the agent. At the same time, compared with the circular second port 21 that directly reduces the diameter, the agent sprayed from the elliptical second port 21 is flat, so that it is dispersed in the injection direction of the auxiliary agent, further increasing the fusion of the agent and the auxiliary agent. It is worth noting that, Figure 7 , Figure 8 As shown, the second port 21 may also be replaced by any other flat-mouth structure.

[0045] As other feasible implementation plans, Figure 8 As shown, the axis of the agent nozzle 2 and the axis of the auxiliary agent nozzle 1 may also have a certain angle, and the agent nozzle 2 and the auxiliary agent nozzle 1 may also have other matching modes, which will not be described in detail in this embodiment.

[0046] Furthermore, the medicine nozzle is an integrated structure, and its end is flattened. The medicine nozzle is divided into two parts, the part close to the medicine nozzle port is a flat tube, and the part away from the medicine nozzle port is a round tube. During the processing, the manufacturer can directly flatten the end of the round tube-shaped medicine nozzle 2 to meet the assembly requirements of the medicine nozzle 2 and the auxiliary agent nozzle 1, which can not only ensure the flow rate of the medicine nozzle 2, but also save processing costs.

[0047] Preferably, the short diameter of the second port 21 is less than half of the diameter of the first port 11 , for example, if the diameter of the first port 11 is 3 mm, the short diameter of the second port 21 is 1.5 mm, 1.2 mm or 0.08 mm, etc., to reserve sufficient space for assembly error.

[0048] Furthermore, the longitudinal section perimeter of the inner wall of the medicine nozzle 2 is always consistent. It is worth noting that when the end of the medicine nozzle is flattened, the longitudinal section perimeter of the inner wall may change slightly due to the ductility of the material of the medicine nozzle itself. This change should also be within the scope of protection of this application. Specifically, the longitudinal section perimeter of the inner wall of the medicine nozzle 2 is at least 3mm to 13mm, such as 4mm, 4.1mm, 5.5mm, 6mm, 9mm, 11mm, 11.5mm or 12mm, etc., to ensure the spraying amount.

[0049] Specifically, the axis of the agent nozzle 2 and the axis of the auxiliary agent nozzle 1 are perpendicular to each other in the horizontal direction, and the angle between the short diameter of the second port 21 and the plumb line is 0° to 30°, such as 5°, 8°, 15° or 20°. Preferably, the angle between the short diameter of the agent nozzle 2 and the plumb line is 0° to 4°.

[0050] More specifically, the distance between the center line of the medicine nozzle 2 and the center line of the auxiliary agent nozzle 1 is 0 mm to 1.2 mm, preferably 0 mm, so that the auxiliary agent and the medicine can fully collide with each other.

[0051] Preferably, the first port 11 is circular to maximize the spraying range. As another optional solution, the first port 11 may also be circular, elliptical or other structures with edges.

[0052] Specifically, the distance between the first port 11 and the second port 21 along the jet direction of the auxiliary agent nozzle 1 is 0mm to 12mm, preferably 0mm to 6mm, such as 1mm, 3mm, 5mm, to prevent the auxiliary agent from being fused with the medicine after the pressure decreases sharply after being sprayed for a distance, resulting in uneven fusion of the auxiliary agent mist and the medicine.

[0053] Preferably, the second port 21 extends into the jet region of the auxiliary agent nozzle 1 so that the auxiliary agent and the medicine can be quickly merged.

[0054] Specifically, the distance between the second port 21 and the axis of the auxiliary agent nozzle is 0.2 mm to 2.5 mm, preferably 0.3 mm to 2 mm, such as 0.4 mm, 0.8 mm, 1 mm, 1.5 mm, to reserve space for the spray jet.

[0055] More specifically, in order to prevent the agent nozzle 2 from causing excessive interference to the mist flow sprayed by the auxiliary agent nozzle 1, the front end of the outer wall of the agent nozzle 2 gradually shrinks to form a cone-like structure to reduce the jet obstruction to the auxiliary agent nozzle.

[0056] The inner wall of the port of the auxiliary agent nozzle 1 has an oblique angle structure, so that the auxiliary agent nozzle 1 opens outward, the auxiliary agent port is further enlarged, and the medicine is further covered.

[0057] As an extension solution, the shape of the second port 21 is adjustable, and is used to flexibly cooperate with the first port 11 to adapt to different steam sprayer operating environments. For example, the medicine nozzle 2 is movably connected with a baffle, and the user can adjust the relative position of the baffle and the medicine nozzle 2 to interfere with the outlet end of the medicine nozzle, so that the shape of the medicine mist sprayed from the second port 2 changes.

[0058] In combination with the above embodiments, since the medicine has a certain consistency, contains certain particles, and its port is tight, it will cause it to be more easily clogged. Preferably, the medicine nozzle 2 is detachably connected to the medicine tube. When the medicine nozzle 2 is clogged, the user can quickly remove the medicine nozzle 2 from the medicine tube and clean the medicine nozzle 2.

[0059] Specifically, the medicine nozzle 2 is inserted into the medicine tube, and a fastener is provided on the outside of the medicine tube for clamping the matching part of the medicine tube and the medicine nozzle to fix the relative position of the two.

[0060] Furthermore, due to the dusty working environment of the sprayer, both the auxiliary agent nozzle 1 and the medicine nozzle 2 are detachable structures. For example, the auxiliary agent nozzle 1 can be threadedly connected to the auxiliary agent pipe, and the medicine nozzle 2 can be threadedly connected to the medicine pipe. The nozzle and the pipe can also be plugged in or other ways. When the user finds that the nozzle is clogged, the nozzle can be removed, and a cleaning tool such as a brush can be inserted into the nozzle channel to clean the nozzle. After cleaning, the nozzle can be installed back into the pipe.

[0061] In this application, the terms "installed", "set", "provided with", "connected", "connected", and "socketed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0062] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
