Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, specifically to a gas-liquid mixing nozzle. Background Technology

[0002] Sprinkler spraying is currently the most common method of irrigation, pest control, and fertilization in orchards. Given the large area and numerous units within orchards, a well-designed sprinkler system can bring significant benefits while simultaneously controlling the costs of pesticides and fertilizers, thus avoiding waste.

[0003] A Chinese patent with publication number CN214708763U discloses a micro-nozzle based on gas-liquid mixing spray. To facilitate installation, this micro-nozzle has spikes at both ends of a connecting tube. These spikes are inserted into an infusion tube or gas delivery tube to connect the two ends of the connecting tube. The liquid or gas in the infusion tube and gas delivery tube mixes in a mixing chamber in the middle of the connecting tube and is then sprayed out from a strip-shaped or circular nozzle at the bottom of the mixing chamber. However, in actual use, it has been found that neither the infusion tube nor the gas delivery tube, whether made of hard plastic or soft rubber hose, can be directly inserted through the spikes of the connecting tube. Drilling is required before insertion, making the installation process more complex and labor-intensive than connecting multiple pipe sections. Furthermore, the connecting pipe is only connected to the infusion or gas supply pipe at both ends via spikes, resulting in extremely poor sealing. Due to thermal expansion and contraction, gaps easily appear at the connection points when the temperature of the transported liquid or gas changes, leading to gas or liquid leakage. Additionally, the design of this miniature sprinkler head limits its application to only two pipes, restricting its use to a single infusion or gas supply function. Moreover, the pressure difference between the infusion and gas supply pipes cannot be too large; otherwise, the connecting pipe will act as an intermediary, causing backflow of fluid within the infusion or gas supply pipe. These factors render this miniature sprinkler head highly impractical and unable to meet the normal needs of garden plants. Therefore, it is necessary to provide a more practical sprinkler head that meets the requirements of garden plants. Utility Model Content

[0004] The purpose of this invention is to provide a gas-liquid mixing nozzle that can atomize pesticides, water, fertilize, and regulate the temperature of the covered area.

[0005] This utility model is achieved through the following technical solution: a gas-liquid mixing nozzle, including a housing, the outer side of which is provided with a connecting pipe structure and the inner cavity is provided with a guide channel. Two guide channels with gradually approaching but not contacting each other pass through the housing to form a converging nozzle. Each set of connecting pipe structures consists of two connectors provided on the upper and lower opposite sides of the housing. The two connectors that make up the same set of connecting pipe structures are interconnected and connected to the converging nozzle through the guide channel.

[0006] The working principle is as follows: By combining pipe joints with nozzles, multiple joints can be connected in series on the pipe to achieve uniform distribution of nozzles and ultimately achieve atomized spraying. The housing contains relatively independent guide channels. One end of each guide channel connects to the joint, i.e., to the pipe, while the other end exits at the confluence nozzle on the side of the housing. Therefore, the different pipes installed on the housing are not connected; the fluids within them converge and are sprayed out through independent guide channels at the confluence nozzle. This allows for independent and mixed operation of each pipe, ensuring a certain atomization effect during gas-liquid mixed spraying and individual liquid spraying, and achieving temperature regulation of the covered area when spraying gas alone.

[0007] To better realize this utility model, further, a guide pipe extending out of the converging nozzle is also installed in the guide channel, and the openings of the two guide pipes at the same converging nozzle are opposite to each other and do not contact each other.

[0008] To better realize this utility model, further, when the guide pipe is not installed, the outlet heights of the two guide channels at the same confluence nozzle are different; when the guide pipe is installed, the outlet heights of the two guide pipes at the same confluence nozzle are different.

[0009] To better realize this utility model, at least one of the two opposite sides of the housing is provided with a buckle for assisting in positioning and installation.

[0010] To better realize this utility model, the buckle opening is further perpendicular to the plane of the housing, or the buckle opening is parallel to the plane of the housing.

[0011] To better realize this utility model, the housing further includes an upper housing and a lower housing, and the upper housing and the lower housing are respectively provided with through joints; the inner surface of the upper housing and the inner surface of the lower housing are both provided with guide grooves, and the guide grooves corresponding to the positions of the upper housing and the lower housing are combined to form a guide channel inside the housing; the upper housing and the lower housing are connected by a convex key and a keyway embedded on opposite surfaces.

[0012] To better realize this utility model, the side of the housing with the converging nozzle is further inclined upward or downward, so that the spray direction of the converging nozzle is inclined upward or downward.

[0013] To better realize this utility model, the connector is further provided with a fixing component for connecting the external pipe to the connector.

[0014] To better realize this utility model, a sealing ring is further provided between the fixing member and the inner wall of the connector.

[0015] To better realize this utility model, the fixing member is further provided with a locking member for locking the external pipe.

[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0017] (1) This utility model combines pipe joints and nozzles, and multiple joints can be connected in series on the pipe to achieve uniform distribution of nozzles and ultimately achieve the purpose of atomized spraying. Due to the structural design of the pipe joint, the pipe and joint can be sealed and there will be no leakage of liquid or gas due to thermal expansion and contraction.

[0018] (2) The present invention has relatively independent guide channels in the shell, so that the different pipes installed on the shell are not connected. The fluids in them are sprayed out at the converging nozzle through independent guide channels. This can realize the independent operation and mixed operation of each pipe. This can avoid the backflow phenomenon caused by the pressure difference of the pipe. It can realize individual liquid or gas spraying, as well as mixed spraying of gas and liquid. Its functionality is greatly improved and its practical effect is enhanced.

[0019] (3) Since this utility model can achieve gas spraying independently, heat source gas can be introduced to achieve air agitation and circulation within the coverage area, thus solving the problem of heating at low temperatures;

[0020] (4) By setting a buckle integrated with the housing, this utility model enables the nozzle to be applicable to various spraying scenarios, solving the problems of variability and stability in actual application scenarios, and effectively reducing installation costs;

[0021] (5) The structure of this utility model is reasonable and the functions are complete. It can make adaptive structural adjustments according to the actual situation to better meet the spraying needs of plants. It can significantly reduce production and usage costs, has good market prospects, and is suitable for widespread promotion and application. Attached Figure Description

For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] Example 1:

[0038] The main structure of this embodiment is as follows: Figure 1 , Figure 2 As shown, the device includes a housing 1. Two pairs of connectors 2 are arranged opposite each other on the upper and lower sides of the housing 1, and these opposite connectors 2 penetrate the housing 1 and communicate with each other. One pair of connectors 2 connects to an infusion tube, and the other pair connects to a gas infusion tube. Inside the housing 1, there is a guide channel 13 communicating with the infusion tube and another guide channel 13 communicating with the gas infusion tube. A converging nozzle 14 is provided on one side of the housing 1. The openings of the two guide channels 13 are located at the converging nozzle 14, and the openings of the two guide channels 13 are opposite each other, with different outlet heights at the converging nozzle 14.

[0039] In practical use, the infusion tube and gas infusion tube are respectively installed at the connectors 2 at both ends of the housing 1, ensuring normal connection between the infusion tube and the gas infusion tube, thus completing the installation of the gas-liquid mixing nozzle. This gas-liquid mixing nozzle has multiple functions, specifically including:

[0040] A. Atomizing Spray Function: Simultaneously opening the valves of the gas supply pipe and the liquid supply pipe allows gas and liquid to be output from these pipes. When the liquid and gas enter the housing 1 through connector 2, the gas or liquid flows through the corresponding guide channel 13 to the converging nozzle 14. The pressure of the gas effectively breaks up the liquid, achieving an atomization effect. The atomization distance and area can be adjusted by regulating the pressure, flow rate, and velocity of the liquid and gas. This function is suitable for spraying pesticides and applying fertilizers.

[0041] B. Spraying Function: Only the valve of the infusion pipe is opened, allowing liquid to be output. As the liquid enters the housing 1 through connector 2, it flows through the corresponding guide channel 13 to the confluence nozzle 14. The liquid impacts the confluence nozzle 14, breaking up large water droplets. The spray distance and coverage area can be adjusted by regulating the pressure, flow rate, and velocity of the liquid supply. This function is suitable for watering or liquid fertilization. Alternatively, the air supply pipe can be replaced with an infusion pipe, i.e., two infusion pipes can be installed on the nozzle. This allows large water droplets to be sprayed directly from the confluence nozzle 14, improving the efficiency of watering or fertilization.

[0042] C. Temperature regulation function within the coverage area: This mainly involves introducing heat source gas through a gas delivery pipe. As the heat source gas passes through the housing 1, it flows through the guide channel 13 to the converging nozzle 14, achieving air agitation and circulation within the coverage area. This solves the heating problem at low temperatures. To improve heating efficiency, the liquid delivery pipe can be replaced with a gas delivery pipe, thus increasing the efficiency of heat source gas delivery. Cooling is relatively simple; ordinary atomizing spray function can achieve a cooling effect at high temperatures.

[0043] Example 2:

[0044] This embodiment, based on the above embodiment, further adds a guide pipe 3 and a fixing component 5, such as... Figure 1 , Figure 2 As shown, a guide pipe 3 is also installed inside the guide channel 13, and the guide pipe 13 can extend from the opening of the guide channel 3 at the confluence nozzle 14. A fixing member 5 is also installed inside the connector 2 to connect the external pipe to the connector 2. The guide pipe 3 can slide within the guide channel 13, thus allowing it to extend at different lengths from the opening of the guide channel 3. This adjustment of the extension length of the guide pipe 3 at the confluence nozzle 14 allows for adjustment of the atomization or water spray effect at the confluence nozzle 14. When using this nozzle for atomization spraying, the guide pipe 13 for the incoming gas can be extended further, allowing for gas-liquid counter-current flow and improved atomization. In water spraying mode, the guide pipe 13 for the incoming water can be extended further, bringing the water flow closer to the confluence nozzle 14 on the other side, resulting in more uniform liquid splashing. The fastener 5 is designed to securely fix the water pipe or infusion pipe to the connector to prevent leakage of liquid or air. It is a common structure in this field and will not be described in detail here.

[0045] Example 3:

[0046] This embodiment further defines the structure of the shell 1 based on the above embodiments, such as... Figure 3As shown, the side of the housing 1 with the converging nozzle 14 is an upward or downward inclined surface, so that the converging nozzle 14 is tilted upward or downward, and the angle between the inclined surface and the plane of the housing 1 is no greater than 35°. In order to achieve a better spraying effect on the plants, depending on the scene and the plant, the side of the converging nozzle 14 of the housing 1 is an inclined surface with an angle of no more than 35° between the plane of the housing 1 and the plane of the housing 1. This can achieve an upward spraying effect, which is beneficial to the coverage of the underside of the plant leaves. The other parts of this embodiment are the same as those of the above embodiment, and will not be repeated here.

[0047] Example 4:

[0048] This embodiment, based on the above embodiment, further adds a buckle 4 structure, such as... Figures 4-7 As shown, the housing 1 has clips 4 for fixing on one or both sides, and the opening of the clips 4 is perpendicular or parallel to the plane of the housing 1. The clips 4 are designed to better fix the gas-liquid mixing nozzle. With a clip on one side, one end of which is fixed to a fixing rod, and clips on both sides, the nozzle is fixed between two fixing rods.

[0049] If the opening of the clip 4 is perpendicular to the plane of the housing 1, then the fixing rod is parallel to the plane of the nozzle housing 1, which is suitable for fixing the nozzle to the horizontal fixing rod for longitudinal spraying. Figure 5 As shown.

[0050] If the opening of the clip 4 is parallel to the plane of the housing 1, then the fixing rod is perpendicular to the plane of the nozzle housing 1, which is suitable for fixing the nozzle to the vertical fixing rod for horizontal spraying. Figure 6 As shown. The other parts of this embodiment are the same as those in the above embodiments, and will not be repeated here.

[0051] Example 5:

[0052] This embodiment further defines the structure of the housing 1 based on the above embodiments, such as... Figure 7 As shown, the device includes a housing 1. Two pairs of connectors 2 are arranged opposite each other on the upper and lower sides of the housing 1, and these opposite connectors 2 penetrate the housing 1 and communicate with each other. One pair of connectors 2 connects to an infusion tube, and the other pair connects to a gas infusion tube. Two guide channels 13 connected to the infusion tube and two guide channels 13 connected to the gas infusion tube are provided inside the housing 1. Converging nozzles 14 are symmetrically arranged on the front and rear sides of the housing 1. The openings of two guide channels 13 are at the front converging nozzle 14, and the other two guide channels 13 are at the rear converging nozzle 14. The openings of the two guide channels 13 at the same converging nozzle 14 are opposite each other, and the outlet heights of the two guide channels 13 at the same converging nozzle 14 are different.

[0053] A converging nozzle 14 is provided at both the front and rear ends of the housing 1. Correspondingly, each converging nozzle 14 is provided with two guide channels 13 with opposite openings. This arrangement enables the spraying process of the plants at both the front and rear ends of the housing 1, thereby improving the spraying efficiency.

[0054] After installing clip 4, the nozzle, such as Figure 8 As shown.

[0055] The specific usage process is as follows: during longitudinal spraying, such as Figure 9 As shown, during horizontal spraying, as Figure 10 As shown, the other parts of this embodiment are the same as those in the above embodiments, and will not be repeated here.

[0056] Example 6:

[0057] This embodiment further defines the structure of the housing 1 based on the above embodiments, such as... Figure 2 , Figure 11 As shown, the housing 1 includes an upper housing 11 and a lower housing 12. A connector 2 penetrating the upper housing 11 is provided on the outer surface of the upper housing 11, and a connector 2 penetrating the lower housing 12 is provided on the outer surface of the lower housing 12. Guide grooves are provided on the inner surfaces of both the upper housing 11 and the lower housing 12, and these guide grooves combine to form a guide channel 13 inside the housing 1. The upper housing 11 and the lower housing 12 are connected by a key and a keyway embedded in their opposing surfaces. Other parts of this embodiment are the same as those in the previous embodiment and will not be described again here.

[0058] Example 7:

[0059] This embodiment further defines the structure of the fastener 5 based on the above embodiment, such as... Figure 11 As shown, a sealing ring 6 is also provided between the fixing member 5 and the inner wall of the connector 2, and the fixing member 5 is also provided with a locking member 7 to lock the external pipe. In order to achieve a better sealing effect and avoid leakage due to thermal expansion and contraction, a sealing ring 6 is specially provided on the fixing member 5 to maintain its better sealing effect, while the addition of the locking member 7 is to lock the pipe and the fixing member 5 to ensure the stability between the pipe and the connector 2. The other parts of this embodiment are the same as those in the above embodiment, and will not be described again.

[0060] It is understood that the working principle and working process of the gas-liquid mixing nozzle structure according to one embodiment of the present invention, such as the fixing member 5 and the locking member 7, are existing technologies and are well known to those skilled in the art, and will not be described in detail here.
