Description

Technical Field

[0001] The invention belongs to the technical field of agricultural spraying tools, in particular to a recyclable spray head. Background Art

[0002] In the agricultural field, sprinklers are one of the common irrigation or fertilization tools. When used, high-speed water is usually flowed into the sprinkler, and then the liquid is squeezed out of the sprinkler by pressure to achieve a wider spraying range. There are two types of irrigation or fertilization: fixed and mobile. The fixed type is mostly used in greenhouses, while the mobile type is mostly used in places where water sources cannot reach.

[0003] Regardless of which method is used for irrigation or fertilization, the current sprinkler nozzles basically use the "Laval principle" in the ejection part to increase the jet flow rate, but these sprinklers all have a common problem. Because the ejection part has a small aperture and a fast flow rate, or the hole is not smooth enough to hinder the water flow, some water cannot form a jet and forms water droplets falling down; irrigation or fertilization is a long process, the water consumption is huge, and a sprinkler nozzle has more than one ejection part, which means that more water may be wasted and not play a role, which is a huge waste especially for areas with scarce water resources;

[0004] In addition, different chemical salts of drugs will be added to the water according to actual conditions. For mobile sprinklers, such as the Chinese patent document "CN117958003A, a garden water supply and fertilization device and its operation method", the side wall of the sprinkler cover is provided with multiple groups of second through holes distributed in a circumferential state, and multiple groups of the spray pipes are fixedly arranged at the positions of the corresponding second through holes of the sprinkler cover, and the lower end surface of each of the spray pipes is connected to multiple groups of evenly spaced atomizing nozzles. Figure 1 , these waters containing medicines will inevitably spray onto the frame or other parts, which will cause corrosion of the frame or parts over a long period of time. Summary of the invention

[0005] The object of the present invention is to provide a recyclable spray head to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A recyclable spray head comprises a connecting portion, a diverting portion and a retrieving portion;

[0008] The connecting part is used to connect with an external water pipe, and a flow channel 1 is provided inside the connecting part;

[0009] The flow dividing part is fixedly arranged at the bottom of the connecting part, and a plurality of flow channels 2 connected with the flow channel 1 are arranged inside the flow dividing part, and the flow channels 2 extend to the side wall, and a plurality of spraying parts are arranged on the side wall of the flow dividing part, and the spraying parts are connected with the flow channel 2;

[0010] The recovery part includes a supporting part with a conical surface, the conical surface covers the spraying part, a through hole 1 is provided at the center of the conical surface, a hard connecting pipe which is connected with the through hole 1 is provided at the bottom of the supporting part, and the other end of the connecting pipe is fixedly arranged at one side of the connecting part and is connected with the flow channel 1;

[0011] The high-speed water flow in the flow channel 1 generates negative pressure at the connecting pipe, so that the liquid accumulated at the cone surface is sucked from the through hole 1 and flows back into the flow channel 1.

[0012] According to a further technical solution, the spraying part includes a fixed block and a nozzle, the fixed block is provided with a water outlet hole 1, the nozzle is connected to the fixed block by threads, the nozzle is provided with a funnel-shaped water outlet hole 2, and one end of the water outlet hole 2 is connected to the water outlet hole 1.

[0013] According to a further technical solution, at least one through hole 2 is provided on the outer side of the connecting portion, and the through hole 2 can be connected to an external medicine box through a pipeline.

[0014] According to a further technical solution, a plurality of irregularly distributed semicircular protrusions are provided on the inner side of the connecting portion.

[0015] According to a further technical solution, a plurality of regularly distributed semicircular protrusions 2 are provided on the inner side of the connecting portion, and the semicircular protrusions 2 gradually become larger from top to bottom.

[0016] According to a further technical solution, the flow channel 1 includes channel 1 and channel 2, the channel 1 is conical, the channel 2 is connected to the conical end of the channel 1, and an arc-shaped transition is formed at the connection.

[0017] A method for using a recyclable nozzle, comprising the recyclable nozzle, and the specific steps are as follows:

[0018] In the first step, the connection part is connected to the external pipe, and a high-speed water flow is introduced into the flow channel 1, and finally the water flow is sprayed outward from the spray part. At the same time, the high-speed water flow flows in the flow channel 1, so that a negative pressure is generated in the connecting pipe and acts on one through hole;

[0019] In the second step, if liquid drips from the end of the spraying part to the conical surface of the bearing part and converges at the center, it will be sucked in from the through hole and flow back to the flow channel one; if there is no liquid on the conical surface, the through hole one will suck in the external air and enter the flow channel one, forming bubbles in the high-speed water flow to assist the mixing of the medicine in the water.

[0020] In a further technical solution, if there is medicine in the high-speed water flow, the second through hole does not need to be connected to the external medicine box. At this time, the negative pressure generated at the second through hole will inhale the external air, so that bubbles are generated in the high-speed water flow to assist the mixing of the medicine;

[0021] When there is no medicine in the high-speed water flow, the second through hole is connected to the external medicine box to suck the liquid medicine in the medicine box into the high-speed water flow for mixing.

[0022] Beneficial effects of the present invention:

[0023] The present invention utilizes the negative pressure generated by high-speed water flow to reflow the liquid gathered in the recovery part into flow channel 1, so that these inconspicuous but consumed water are concentrated and recycled, which can greatly save water resources in areas where water resources are scarce. Secondly, since the medicines in the liquid may cause corrosion to the equipment, these can be collected by the support part 31 to prevent the liquid from dripping or splashing directly onto the mobile device.

[0024] Other features and advantages of the present invention will be described in detail in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] Please refer to Figure 1-6 ;

[0034] The nozzle described in the present invention aims to collect the water that would otherwise be wasted and return it to the nozzle, and specifically includes a connecting portion 11, a diverting portion 2 and a recovery portion, wherein the connecting portion 11 is used to connect to an external water pipe, and a flow channel 1 4 is provided inside the connecting portion 11. In this embodiment, the external shape of the connecting portion 11 is not limited, and it can be determined specifically according to the connected components, but the flow channel 1 4 is cylindrical, and is intended to reduce the resistance generated by the flow of the liquid. The diverting portion 2 is fixedly arranged at the bottom of the connecting portion 11, and a plurality of flow channels 2 5 connected to the flow channel 1 4 are provided inside the diverting portion 2, and the flow channel 2 5 extends to the side wall, and a plurality of spraying portions 6 are provided on the side wall of the diverting portion 2, and the spraying portions 6 are connected to the flow channel 2 5; the recovery portion includes a supporting portion 31 provided with a conical surface 32, a through hole 1 33 is provided at the center of the conical surface 32, and a connecting pipe 34 penetrating the through hole 1 33 is provided at the bottom of the supporting portion 31, and the other end of the connecting pipe 34 is fixedly arranged on one side of the connecting portion 11 and is connected to the flow channel 1 4;

[0035] Specifically, a small-diameter hole connected to the flow channel 4 is provided on the outer side of the connecting portion 11, and the other end of the connecting pipe 34 is inserted into the hole, and then fixed and sealed by welding. In this embodiment, the connecting pipe 34 is made of a hard material, such as stainless steel, copper or other high-strength alloys that are not easy to deform, and its shape is roughly "C"-shaped. After one end of the connecting pipe 34 is fixed to the connecting portion 11, the supporting portion 31 can be fixed below the spraying portion 6 by utilizing the characteristics of the hard material; in addition, in order to completely catch the liquid dripping from the spraying portion 6, the outermost edge of the conical surface 32 covers the spraying portion 6; preferably, a retaining edge can be provided on the outer edge of the conical surface 32 to prevent the liquid falling on the conical surface 32 from splashing;

[0036] During operation, the external device flows high-speed water into the flow channel 1 4, and then into each flow channel 2 5 in the diversion part 2. The cross-sectional diameter of the flow channel 2 5 is smaller than the cross-sectional diameter of the flow channel 1 4. When the water flows from the flow channel 1 4 into the flow channel 2 5, it will be accelerated, and finally sprayed out from the spraying part 6 to the outside. A small part of the liquid output to the outside by the spraying part 6 cannot be sprayed out due to various factors, but will form water droplets. Since irrigation or fertilization is a long process, several spraying parts 6 continue to spray liquid, and water droplets will continue to fall at several spraying parts 6. In this embodiment, the falling water droplets will drip onto the conical surface 32 of the supporting part 31 and will gather at the center of the conical surface 32.

[0037] At the same time, the high-speed water flow will form a negative pressure at the connecting pipe 34. This is a continuous process. The negative pressure will suck the liquid gathered at the center of the cone 32 from the through hole 33 and re-enter the flow channel 4 through the connecting pipe 34 to form a circulation. Since this is a continuous process, these inconspicuous but consumed water can be concentrated and recycled, which can greatly save water resources in areas with scarce water resources. Secondly, since the drugs in the liquid may cause corrosion to the equipment, they can be collected by the supporting part 31 to prevent the liquid from dripping or splashing directly onto the mobile device.

[0038] In addition, for fertilization or insecticide, chemicals are usually fully mixed with water before being sprayed. If the amount of absorbable reflux is greater than the amount of liquid gathered at the cone 32, that is, no water is sucked into the cone 32, but negative pressure is still generated at the through hole 33, external air will be sucked in and bubbles will be formed in the high-speed water flow when entering the flow channel 4. The bubble rupture process assists the further mixing of chemicals and water. In particular, for solid drugs, there are still undissolved solid particles in the preliminary mixing in the water tank. By mixing the bubbles at the flow channel 4 and then performing the final mixing process, the solids gathered together are broken up by bubble rupture, thereby improving the mixing effect and avoiding blockage of the spraying part 6. Furthermore, the bottom surface of the diversion part 2 is inclined to guide the water droplets to the center.

[0039] It should be noted that the nozzles in the drawings of the present invention are for illustration of the principle and do not represent the final form. For example, the spraying portion 6 in the drawings is arranged in a circular array, but in actual production the spraying portion 6 may be arranged to one side, etc.

[0040] In one of the embodiments of the spraying part 6 of the present invention, it specifically includes a fixed block 61 and a nozzle 62. A water outlet hole 1 63 is provided at the fixed block 61. The nozzle 62 is connected to the fixed block 61 by a thread. A funnel-shaped water outlet hole 2 64 is provided in the nozzle 62. One end of the water outlet hole 2 64 is connected to the water outlet hole 1 63. In the prior art, the "Laval principle" is usually adopted to further accelerate the sprayed water. The water outlet hole 2 64 in this embodiment is usually the same principle. In this implementation, a detachable and replaceable method is adopted. Specifically, water outlet holes 2 64 with different apertures can be set to achieve different water outlet effects. Users can choose according to actual conditions without replacing the nozzle as a whole.

[0041] In the embodiment of the present invention, at least one second through hole 12 is provided on the outer side of the connecting portion 11. In one use mode, the second through hole 12 is not connected to an external component. At this time, the second through hole 12 is directly connected to the outside world, and the high-speed water flow will also form a negative pressure at the second through hole 12, thereby sucking in external air to form bubbles in the high-speed water flow;

[0042] Another use method is that the through hole 12 is connected to an external medicine box through a pipeline, and liquid medicine is stored in the medicine box; usually, a high-speed water flow needs to be increased by a high-pressure pump to form. In the traditional method, chemical drugs are mixed with water and then transported to the nozzle through a water pump, which means that the liquid containing drugs will contact the water pump, causing corrosion or blockage to the water pump after a long time;

[0043] The liquid in the medicine box is sucked into the flow channel 14 by the high-speed water flow, and then the medicine is mixed with the high-speed water flow, that is, the water pump only needs to be responsible for providing water, and the cost of replacing the nozzle is lower than that of replacing the water pump; in addition, under normal circumstances, the medicine and water are mixed in a large proportion, so the amount of medicine sucked in per unit time does not need to be too much;

[0044] In the early stage, the medicine box can be pressurized to discharge the air in the pipe. Even if the pressure in the medicine box is restored to the same value as that in the outside world, as long as there is a continuous high-speed water flow in flow channel 1-4, the air pressure in flow channel 1-4 will always be lower than the pressure in the medicine box, and the medicine can be smoothly sucked into flow channel 1-4.

[0045] Of course, a connecting portion 11 may be provided at the second through hole 12 , and the connecting portion 11 is sealed and connected to the pipeline.

[0046] In the embodiment of the present invention, a plurality of irregularly distributed semicircular protrusions 13 are provided on the inner side of the connecting portion 11, and the semicircular protrusions 13 play a role in assisting the mixing of medicine and water.

[0047] In another embodiment, referring to Figure 5 A number of regularly distributed semicircular protrusions 14 are provided on the inner side of the connecting portion 11, and the semicircular protrusions 14 gradually become larger from top to bottom. In addition to assisting the mixing of drugs and water, this method can also gradually reduce the space of the flow channel 4, thereby further compressing the high-speed water flow and increasing the flow rate.

[0048] In another embodiment, referring to Figure 6 , flow channel 1 4 includes channel 1 41 and channel 2 42, channel 1 41 is tapered, channel 2 42 is connected to the tapered end of channel 1 41, and there is an arc transition at the connection. Simply put, it gradually becomes smaller from channel 1 41 to channel 2 42, thereby achieving the effect of further increasing the flow rate.

[0049] The present invention also discloses a method of use, including the recyclable nozzle in the above embodiment, and the specific steps are as follows:

[0050] In the first step, the connection part 11 is connected to the external pipe, and a high-speed water flow is introduced into the flow channel 1 4, and finally the water flow is sprayed outward from the spray part 6. At the same time, the high-speed water flow flows in the flow channel 1 4, so that a negative pressure is generated in the connecting pipe 34 and acts on the through hole 1 33;

[0051] In the second step, if liquid drips from the end of the spraying portion 6 to the conical surface 32 of the bearing portion and converges at the center, it will be sucked in from the through hole 33 and flow back into the flow channel 4; if there is no liquid at the conical surface 32, the through hole 33 will suck in external air and enter the flow channel 4, forming bubbles in the high-speed water flow to assist in mixing the medicine in the water.

[0052] Furthermore, if there is medicine in the high-speed water flow, the second through hole 12 does not need to be connected to the external medicine box. At this time, the negative pressure generated at the second through hole 12 will suck in external air, so that bubbles are generated in the high-speed water flow to assist in mixing the medicine;

[0053] When there is no medicine in the high-speed water flow, the second through hole 12 is connected to the external medicine box to suck the liquid medicine in the medicine box into the high-speed water flow for mixing.

[0054] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
