It includes a flange, one side of which connects to an elbow, and the other end of the elbow connects to a main spray pipe. The other end of the main spray pipe connects to a threaded connector. The other end of the connector is threaded into the inside of one end of the outer casing. In this utility model, when water is sprayed in shower mode, the nozzle is removed from the inside of the pressure cap, and then a bolt is passed through the mounting post and connected to the stop block. A certain gap is left between the small end of the stop block and the inner wall of the connector end.

In this mode, when water flows from the main spray pipe into the connector, the water flow is initially divided by six dividing plates. Then, as the water flow continues, the divided water flow will gush out from the gap between the connector and the stop block, thus allowing the water to spray in shower mode.

Description

Technical Field

[0001] This utility model belongs to the field of spray head technology, specifically relating to a spray head that can switch between water jet focusing and shower modes. Background Technology

[0002] In agricultural production, sprinklers are key equipment for farmland irrigation, and their performance directly affects crop growth and yield. Traditional agricultural irrigation sprinklers usually adopt a single spraying mode or a fixed shower-style spray, which cannot be flexibly adjusted according to the water requirements and irrigation needs of crops at different growth stages.

[0003] During the seedling stage of crops, a gentle, even spray is needed to avoid damaging the seedlings with excessive water flow. However, during the vigorous growth stage, a jet of water is required to irrigate deeper soil layers in order to improve irrigation efficiency and penetration. However, existing sprinklers cannot meet multiple irrigation needs simultaneously. Frequent sprinkler replacements not only increase labor costs but also damage the equipment and reduce its lifespan due to disassembly and reassembly.

[0004] In view of the shortcomings of the existing technology, there is an urgent need for a spray head that can flexibly switch between two spray modes: shower head and column spray. Utility Model Content

[0005] The purpose of this invention is to provide a spray nozzle that can switch between water jet focusing and shower spray modes. This addresses the need for gentle, even shower spraying during the seedling stage of crops to avoid damaging seedlings with excessive water flow; and the requirement for a jet-like water flow to irrigate deeper soil during the vigorous growth stage to improve irrigation efficiency and penetration. However, existing nozzles struggle to meet these diverse irrigation needs, and frequent nozzle replacements not only increase labor costs but also damage the equipment and reduce its lifespan due to disassembly and reassembly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spray nozzle that can switch between water jet focusing and shower modes, including a flange, one side of which is connected to an elbow, the other end of which is connected to a main spray pipe, and the other end of the main spray pipe is connected to a threaded connector.

[0007] The other end of the connector is threaded into the inside of one end of the housing. A pressure cap is threaded into the other end of the housing. A nozzle is installed inside the pressure cap. The nozzle has a frustum structure and a frustum-shaped through hole inside the nozzle. The outer edge of the nozzle with the large end open is pressed and installed inside the housing by the pressure cap.

[0008] To prevent leakage at the connection between the nozzle and the housing during water flow, the spray head of this invention, which allows for switching between water jet focusing and shower modes, preferably includes a sealing ring on the outer wall of the larger end of the nozzle.

[0009] The other side of the ring abuts against the inner wall of the protruding end inside the outer shell, and the outer shell, the pressure cap and the nozzle are connected by the sealing ring to form a partial structure.

[0010] In order to divide the water flowing through the connector into six parts by the dividing plates, as the spray nozzle of this utility model that can switch between water jet focusing and shower mode, preferably, the connector has an internal mounting post at one end inside the outer shell, a set of dividing plates are installed at equal intervals on the outer wall of the mounting post, the other side of the dividing plates is welded to the inner wall of the connector, and six dividing plates are installed at equal intervals on the outer wall of the mounting post.

[0011] A bolt is threaded through the center end of the mounting post, and a stop block is threaded through the other end of the bolt. The end of the stop block extends into the interior of the large end of the nozzle. The stop block has a frustum structure, and the size of the small end of the stop block is smaller than the inner diameter of one end of the connector.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] When water needs to be sprayed in shower mode, remove the nozzle from inside the pressure cap, then pass the bolt through the mounting post and align it with the stop block. Leave a gap between the small end of the stop block and the inner wall of the connector end. Then, install the outer shell and pressure cap sequentially at one end of the connector. In this mode, when water flows from the main spray pipe into the connector, the water flow is initially divided by six dividing plates. Then, as the water flow continues, the divided water will gush out from the gap between the connector and the stop block, thus spraying water in shower mode.

[0014] When it is necessary to concentrate the water flow into a jet, remove the pressure cap, then install the nozzle and sealing ring inside the housing in sequence. After installation, move the pressure cap onto the outer wall of the nozzle and into the housing. Tighten the pressure cap and housing, and the nozzle can be installed at the outlet end of the connector. At this time, the water flow will gush out from the gap between the connector and the baffle and will be concentrated along the frustum-shaped channel inside the nozzle, so that the sprayed water flows out in a jet shape.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4. This utility model provides the following technical solution: a spray nozzle that can switch between water jet focusing and shower mode, including a flange 1, one side of the flange 1 is connected to an elbow 2, the other end of the elbow 2 is connected to a main spray pipe 3, and the other end of the main spray pipe 3 is threadedly connected to a connector 4.

[0022] The other end of the connector 4 is threaded into the inside of one end of the housing 5. The other end of the housing 5 is threaded into a pressure cap 6. A nozzle 7 is installed inside the pressure cap 6. The nozzle 7 has a frustum structure and a frustum-shaped through hole inside the nozzle 7. The outer edge of the nozzle 7, which is open at the large end, is pressed and installed inside the housing 5 by the pressure cap 6.

[0023] The connector 4, housing 5, pressure cap 6, and nozzle 7 are assembled in a groove to form the spray head involved in this technical solution.

[0024] When in use, it is connected to the water supply pipe through flange 1. When the water supply pipe supplies water, the water will flow through elbow 2 into the main spray pipe 3, and then flow into the spray nozzle, and finally flow out from the spray nozzle. In this way, the corresponding agricultural plants can be irrigated through this structure.

[0025] Preferably, a sealing ring 71 is provided on the outer wall of the large end of the nozzle 7, and the other side of the sealing ring 71 abuts against the inner wall of the protruding end inside the housing 5. The housing 5, the pressure cap 6 and the nozzle 7 are connected by the sealing ring 71 to form a partial structure.

[0026] In practical use, when it is necessary to install the nozzle 7 inside the pressure cap 6, first install the sealing ring 71 on the protruding end inside the housing 5, then insert the larger end of the nozzle 7 into the inside of the housing 5, and align the bottom of the nozzle 7 with the sealing ring 71. Then, place the pressure cap 6 on the outer wall of the nozzle 7, move the pressure cap 6 into the inside of the housing 5, and finally fix the pressure cap 6 inside the housing 5 using the threaded structure between the pressure cap 6 and the housing 5.

[0027] After the pressure cap 6 is fixed inside the housing 5, one end of the pressure cap 6 will press the edge of the nozzle 7 tightly against the outer wall of the sealing ring 71. In this way, the other side of the sealing ring 71 will be sealed and fitted with the inner wall of the housing 5. Thus, when in use, the connection end of the housing 5, the pressure cap 6 and the nozzle 7 can form a good sealing structure.

[0028] Preferably, the connector 4 is provided with a mounting post 41 inside one end of the housing 5, and a set of dividing pieces 42 are installed at equal intervals on the outer wall of the mounting post 41. The other side of the dividing pieces 42 is welded to the inner wall of the connector 4, and six dividing pieces 42 are installed at equal intervals on the outer wall of the mounting post 41.

[0029] A bolt 43 is threaded through the center end of the mounting post 41, and a stop block 44 is threaded through the other end of the bolt 43.

[0030] The end of the nozzle 7 extends into the interior of the large end of the nozzle 7. The stop block 44 is a frustum structure, and the size of the small end of the stop block 44 is smaller than the inner diameter of one end of the connector 4.

[0031] In actual use, a certain gap is left between the outer wall of the small end of the baffle 44 and the inner wall of the outlet of the connector 4, so that the water can flow out normally.

[0032] The shower mode adjustment and working principle are as follows:

[0033] When water needs to be sprayed in shower mode, disassembly is performed first. This is done by removing the nozzle 7 from inside the pressure cap 6, while the pressure cap 6 remains separate from the connector 4. Next, select the bolt 43 and pass it through the pre-drilled hole on the mounting post 41, aligning it with the threaded hole of the stop block 44. When installing the stop block 44, a 5-8mm annular gap must be maintained between the smaller end of the stop block 44 and the end of the connector 4; this gap is crucial for creating a shower-like water flow.

[0034] Next, the outer shell 5 and the pressure cap 6 are sequentially fitted onto one end of the connector 4, and the pressure cap 6 is tightly fixed to the connector 4 by screwing them together.

[0035] During shower mode operation, the water flow enters the connector 4 from the main nozzle 3 and first encounters six evenly distributed dividing plates 42 inside the connector 4. These dividing plates 42 are arranged radially, and their edges initially cut the water flow into six fine streams. As the water flow continues to advance inside the connector 4, the divided fine streams gush out from the annular gap between the connector 4 and the baffle 44. Due to the constraint of the gap and the pressure of the water flow itself, the water flow forms a scattering pattern when sprayed, thus achieving a shower-like spraying effect.

[0036] The adjustment and working principle of the water column focusing mode are as follows:

[0037] When it is necessary to concentrate the water flow into a jet, the operation procedure differs from the shower mode. First, the pressure cap 6 needs to be removed from the connector 4. Then, the sealing ring 71 and the nozzle 7 are installed inside the housing 5 in sequence. The sealing ring 71 acts as a seal to prevent water leakage from the connection between the nozzle 7 and the housing 5. During installation, ensure that the sealing ring 71 fits tightly against the bottom of the nozzle 7. After installation, place the pressure cap 6 on the outer wall of the nozzle 7 and move it inward along the inner wall of the housing 5. By rotating the pressure cap 6 clockwise, it is tightly engaged with the threads of the housing 5, thus securely installing the nozzle 7 at the outlet end of the connector 4.

[0038] In columnar mode, the water jet exits through the gap between connector 4 and baffle 44 and directly enters the frustum-shaped channel inside nozzle 7. This channel has a structure that is wider at the top and narrower at the bottom, which can concentrate the dispersed water flow. As the water flows within the frustum-shaped channel, the cross-sectional area of ​​the water gradually decreases, the flow velocity continuously increases, and finally it is ejected in the form of a high-pressure column.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand its limitations.

[0040] Modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
