Description

Technical Field

[0001] This utility model belongs to the field of garden irrigation technology, and specifically relates to a water-saving sprinkler head. Background Technology

[0002] With the continuous improvement of urban greening levels, the maintenance and irrigation of garden plants are becoming increasingly frequent. Sprinkler irrigation systems, as a common method of garden irrigation, offer uniform spraying and convenient operation, effectively improving the efficiency of greening maintenance. However, in long-term use, traditional sprinkler structures generally suffer from problems such as fixed water output, insufficient atomization, and poor response to water pressure fluctuations. This not only leads to waste of irrigation water but also affects the absorption efficiency of plant roots, reducing the scientific and economical nature of irrigation.

[0003] Most existing garden sprinklers use a fixed-hole structure to deliver water for irrigation. When the water pressure in the water supply system fluctuates greatly, the water output of the sprinkler is unstable. For example, under high pressure, a large amount of water is sprayed directly from the sprinkler, which not only aggravates local waterlogging and damages plant roots, but also wastes a lot of water resources. Under low pressure, the water output of the sprinkler is insufficient and cannot meet the irrigation needs of plants, resulting in poor irrigation quality. Utility Model Content

[0004] The present invention provides a water-saving sprinkler head that automatically adjusts the water output of the sprinkler head according to the water pressure of the water supply system, thereby improving the stability of the water output, improving irrigation quality, and saving water resources.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This utility model discloses a water-saving sprinkler head, comprising a connecting seat and a nozzle. The connecting seat includes a threaded joint and a turbulence chamber connected in communication. The nozzle is disposed at the other end of the turbulence chamber opposite to one end of the threaded joint. A pressure regulating mechanism is provided inside the turbulence chamber. The pressure regulating mechanism includes a dividing plate, a guide ring, and a flow regulating plate. A guide hole, a second through hole, and a first through hole are sequentially opened from the center outward along the radial direction of the dividing plate. A support column is vertically arranged on the upper end face of the dividing plate along the periphery of the guide hole. The guide ring is fixedly disposed on the upper end of the support column. A guide column is fixedly disposed at the top of the flow regulating plate. The free end of the guide column passes through the guide hole and the guide ring in sequence. A limiting ring is fixedly sleeved on the outer wall of the guide column. The limiting ring is located above the dividing plate. The outer diameter of the limiting ring is larger than the inner diameter of the guide hole. A spring is sleeved on the guide column. The two ends of the spring are respectively connected to the limiting ring and the guide ring. When the spring is compressed, causing the flow regulating plate to fit against the dividing plate, the flow regulating plate covers the second through hole.

[0007] Furthermore, there are four of each of the second and first through holes, and the second and first through holes are evenly spaced around the guide hole in the circumferential direction.

[0008] Furthermore, the three support columns are evenly arranged along the periphery of the guide hole, and the guide ring is fixedly disposed at the top of the support columns.

[0009] Furthermore, a sealing ring is provided at the bottom of the dividing plate to cooperate with the flow regulating plate. When the flow regulating plate is in contact with the dividing plate, the outer side wall of the flow regulating plate is in contact with the inner side wall of the sealing ring.

[0010] Furthermore, a flow-dispersing component is fixedly installed inside the flow-dispersing chamber. The flow-dispersing component is an inverted funnel-shaped structure, and spiral blades are arranged around the inner sidewall of the flow-dispersing component. The outlet of the flow-dispersing component is connected to the nozzle.

[0011] Furthermore, the nozzle has a base at its bottom, which is connected to the turbulence chamber. The base has a connecting pipe, and the inlet of the connecting pipe is connected to the outlet of the turbulence element.

[0012] Furthermore, multiple atomizing heads are evenly distributed on the top of the nozzle.

[0013] The beneficial effects of this utility model are:

[0014] This application discloses a water-saving sprinkler head. One end of the turbulence chamber is equipped with a threaded connector, and the other end with a nozzle. The threaded connector is mounted on a connector on a water delivery pipe. Water flows from the water delivery pipe into the threaded connector, then through the threaded connector into the turbulence chamber, and is sprayed out from the nozzle to irrigate garden plants. A pressure regulating mechanism is installed inside the turbulence chamber. This mechanism includes a dividing plate, a guide ring, and a flow regulating plate. Along the radial direction of the dividing plate, from the center outwards, there are a guide hole, a second through hole, and a first through hole. A support column is vertically installed on the upper end face of the dividing plate along the periphery of the guide hole. The guide ring is fixedly installed on the upper end of the support column. A guide column is fixedly installed at the top of the flow regulating plate. The free end of the guide column passes through the guide hole and the guide ring in sequence. A limiting ring is fixedly sleeved on the outer wall of the guide column, located above the dividing plate. The outer diameter of the limiting ring is larger than the inner diameter of the guide hole. A spring is sleeved on the guide column. The two ends of the spring are connected to a limiting ring and a guide ring, respectively. When the spring is compressed, the flow regulating plate and the dividing plate are in contact, and the flow regulating plate covers the second through hole. The dividing plate, the first through hole, the second through hole, the guide hole, the guide ring, the flow regulating plate, the guide column, the limiting ring, the spring, and the support column constitute a pressure regulating mechanism. The dividing plate divides the turbulence chamber into an upper chamber near the nozzle and a lower chamber near the threaded joint. The water flows from the water delivery pipe into the threaded joint, enters the lower chamber of the turbulence chamber through the threaded joint, and enters the upper chamber of the turbulence chamber through the first and second through holes of the dividing plate and is sprayed out from the nozzle. Initially, the spring is in its initial state. When the water pressure in the water supply system is high, the impact force of the water flow on the regulating plate is greater than the spring force. Under the impact of the water flow, the regulating plate moves towards the dividing plate, causing the guide column to move towards the guide ring. This causes the limiting ring on the guide column to move towards the guide ring, causing the spring connected between the limiting ring and the guide ring to compress and store energy along the guide column until the regulating plate and the dividing plate are in contact. The regulating plate then covers and seals the second through hole, limiting the water flow. The water flow can only enter the upper chamber of the turbulence chamber through the first through hole. The limited water flow is then sprayed out from the nozzle, reducing the nozzle output. Water volume is controlled to avoid localized waterlogging and conserve water resources. When the water pressure in the water supply system decreases, the impact force of the water flow on the regulating plate is less than the spring force. At this time, under the action of the spring force, the spring releases its stored elastic potential energy and extends, causing the limiting ring and guide column to move away from the guide ring, and causing the regulating plate to move away from the dividing plate until the regulating plate separates from the dividing plate. The second through hole opens to supplement the water flow. The water flows through the first and second through holes into the upper chamber of the turbulence chamber, ensuring that more water flows into the upper chamber of the turbulence chamber, and then sprays out from the nozzle to meet the irrigation needs of plants, improve the stability of the nozzle water output, and improve irrigation quality.In summary, the water-saving sprinkler of this application automatically opens and closes the second through hole according to the water pressure changes in the water supply system. Under high water pressure, the second through hole is blocked by the flow regulating plate, leaving only the first through hole open for flow restriction, thus avoiding local soil water accumulation and saving water. Under low water pressure, the flow regulating plate separates from the second through hole, the second through hole opens to supplement the water flow, and the first and second through holes are open for flow, thereby effectively controlling the water output of the sprinkler, improving the stability of the sprinkler output, and enhancing the water-saving effect and irrigation quality.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, an embodiment of this utility model provides a water-saving sprinkler head, including a connecting seat 1 and a nozzle 4. The connecting seat 1 includes a threaded connector 11 and a flow-dispersing chamber 12 that are connected in communication. The nozzle 4 is disposed at the other end of the flow-dispersing chamber 12 opposite to one end of the threaded connector 11. A pressure regulating mechanism 2 is provided inside the flow-dispersing chamber 12. The pressure regulating mechanism 2 includes a dividing plate 21, a guide ring 22, and a flow-adjusting plate 23. A guide hole 213, a second through hole 212, and a first through hole 211 are sequentially opened from the center outward along the radial direction of the dividing plate 21. A support column 221 is vertically arranged on the upper end surface of the dividing plate 21 along the periphery of the guide hole 213. The guide ring 22 is fixedly disposed on the upper end of the support column 221. The flow-adjusting plate... A guide post 24 is fixedly provided at the top of the 23. The free end of the guide post 24 (the free end of the guide post 24 is the other end of the end that is fixedly connected to the flow regulating disk 23) passes through the guide hole 213 and the guide ring 22 in sequence. A limiting ring 241 is fixedly sleeved on the outer wall of the guide post 24. The limiting ring 241 is located above the dividing disk 21. The outer diameter of the limiting ring 241 is larger than the inner diameter of the guide hole 213. A spring 25 is sleeved on the guide post 24. The two ends of the spring 25 are respectively connected to the limiting ring 241 and the guide ring 22. When the spring 25 is compressed and drives the flow regulating disk 23 to fit with the dividing disk 21, the flow regulating disk 23 covers the second through hole 212. The spring 25 is a compression spring. When the spring 25 is at its free length, the limiting ring 241 is in contact with the dividing plate 21. The distance between the limiting ring 241 and the flow regulating plate 23 is less than the maximum compression length of the spring 25, ensuring that the compression of the spring 25 drives the flow regulating plate 23 to contact and cover the second through hole 212. The number of the second through hole 212 and the first through hole 211 is at least two, such as two, three, or four. In order to better support the guide ring 22, the number of support columns 221 is at least two. The threaded connector 11 is used to install the nozzle on the connecting seat on the water delivery pipe. The threaded connector 11 and the water delivery pipe can also be replaced with existing detachable connection methods such as snap-fit ​​or flange connection. The dividing plate 21 is fixedly snapped or welded in the turbulence chamber 12, dividing the turbulence chamber 12 into an upper chamber near the nozzle 4 and a lower chamber near the threaded connector 11.

[0027] A water-saving sprinkler based on the above structure has a threaded connector 11 at one end of the turbulence chamber 12 and a nozzle 4 at the other end. The threaded connector 11 is installed on a connector on the water delivery pipe. Water flows from the water delivery pipe into the threaded connector 11, enters the turbulence chamber 12 through the threaded connector 11, and is sprayed out from the nozzle 4 to irrigate the plants in the garden. A pressure regulating mechanism is installed inside the turbulence chamber 12. This mechanism includes a dividing disc 21, a guide ring 22, and a flow regulating disc 23. Along the radial direction of the dividing disc 21, from the center outwards, there are sequentially formed guide holes 213, a second through hole 212, and a first through hole 211. A support column 221 is vertically arranged along the circumference of the guide hole 213 on the upper end face of the dividing disc 21. The guide ring 22 is fixedly installed at the upper end of the support column 221. A guide column 24 is fixedly installed at the top of the flow regulating disc 23. The free end of the guide column 24 passes through the guide hole 213 and the guide ring 22 sequentially. A limiting ring 241 is fixedly fitted onto the outer wall of the guide column 24. The limiting ring 241 is located above the dividing disc 21, and its outer diameter is larger than the inner diameter of the guide hole 213 to prevent it from sliding out of the guide hole 213 and detaching from the dividing disc 21. 1. A spring 25 is fitted onto the guide post 24. The two ends of the spring 25 are connected to the limiting ring 241 and the guide ring 22, respectively. When the spring 25 is compressed, the flow regulating plate 23 is brought into contact with the dividing plate 21, and the flow regulating plate 23 covers the second through hole 212. The dividing plate 21, the first through hole 211, the second through hole 212, the guide hole 213, the guide ring 22, the flow regulating plate 23, the guide post 24, the limiting ring 241, the spring 25, and the support post 221 form a pressure regulating mechanism. The dividing plate 21 divides the turbulence chamber 12 into an upper chamber near the nozzle 4 and a lower chamber near the threaded joint 11. The water flows from the water delivery pipe into the threaded joint 11, enters the lower chamber of the turbulence chamber 12 through the threaded joint 11, and enters the upper chamber of the turbulence chamber 12 through the first and second through holes of the dividing plate 21 and is sprayed out from the nozzle.Initially, spring 25 is in its initial state. When the water pressure in the water supply system is high, the impact force of the water flow on the regulating plate 23 is greater than the spring force. Under the impact of the water flow, the regulating plate 23 moves towards the dividing plate 21, causing the guide column 24 to move towards the guide ring 22. This causes the limiting ring 241 on the guide column 24 to move towards the guide ring 22, which in turn causes the spring 25, connected between the limiting ring 241 and the guide ring 22, to compress and store energy along the guide column 24 until the regulating plate 23 and the dividing plate 21 come into contact. The regulating plate 23 then covers the second through hole 213, sealing it and limiting the water flow. The water can only enter the upper chamber of the turbulence chamber 12 through the first through hole 211. The limited water flow is then sprayed out from the nozzle 4. Reducing the water output of the nozzles avoids localized water accumulation in the soil and conserves water. When the water pressure in the water supply system decreases, the impact force of the water flow on the regulating plate 23 is less than the elastic force of the spring 25. At this time, under the action of the elastic force of the spring 25, the spring 25 releases the stored elastic potential energy and extends, causing the limiting ring 241 and the guide post 24 to move away from the guide ring 22, and causing the regulating plate 23 to move away from the dividing plate 21, until the regulating plate 23 separates from the dividing plate 21. The second through hole 212 opens to supplement the water flow. The water flows through the first through hole 211 and the second through hole 212 into the upper chamber of the turbulence chamber 12, ensuring that more water flows into the upper chamber of the turbulence chamber 12, and then sprays out from the nozzle 4 to meet the irrigation needs of plants, improve the stability of the nozzle water output, and improve the irrigation quality. In summary, the water-saving sprinkler of this application automatically opens and closes the second through hole 212 according to the water pressure changes in the water supply system. Under high water pressure, the second through hole 212 is blocked by the flow regulating plate 23, leaving only the first through hole 211 open for flow restriction, thus avoiding local soil water accumulation and saving water. Under low water pressure, the flow regulating plate 23 separates from the second through hole 212, the second through hole 212 opens to supplement the water flow, and the first through hole 211 and the second through hole 212 flow together, thereby effectively controlling the water output of the sprinkler, improving the stability of the sprinkler output, and improving the water-saving effect and irrigation quality.

[0028] As one possible implementation method, such as Figure 3 , Figure 4 As shown, there are four of each of the second through holes 212 and the first through holes 211, and the second through holes 212 and the first through holes 211 are evenly spaced around the guide hole 213 in the circumferential direction.

[0029] Four second through holes 212 and four first through holes 211 are evenly spaced around the guide hole 213, which helps the water flow evenly through the dividing plate 21 to the nozzle 4.

[0030] As one possible implementation method, such as Figure 3As shown, the three support columns 221 are evenly arranged along the periphery of the guide hole 213, and the guide ring 22 is fixedly arranged at the top of the support column 221.

[0031] Three support columns 221 are evenly distributed around the guide hole 213, which provides better stable support for the guide ring 22, while reducing manufacturing costs and weight.

[0032] As one possible implementation method, such as Figure 3 , Figure 4 As shown, the bottom of the dividing disk 21 is provided with a sealing ring 214 that cooperates with the flow regulating disk 23. When the flow regulating disk 23 is in contact with the dividing disk 21, the outer side wall of the flow regulating disk 23 is in contact with the inner side wall of the sealing ring 214.

[0033] The sealing ring 214 is embedded in the annular groove of the dividing plate 21 and is made of elastic material, which has good sealing performance. When the flow regulating plate 23 moves upward after being impacted by water flow under high water pressure, it fits and is sleeved in the sealing ring 214, thereby sealing the second through hole 212. Water flow can only enter the turbulence chamber 12 through the first through hole 211, thus achieving better flow restriction and water saving function.

[0034] As one possible implementation method, such as Figure 1 , Figure 5 As shown, a flow-disrupting component 3 is fixedly installed inside the flow-disrupting chamber 12. The flow-disrupting component 3 is an inverted funnel-shaped structure. Spiral blades 31 are arranged around the inner sidewall of the flow-disrupting component 3. The outlet of the flow-disrupting component 3 is connected to the nozzle 4.

[0035] The inverted funnel-shaped baffle 3 has spiral blades 31 arranged around its inner wall. Before entering the nozzle 4, the water flow forms a vortex-like disturbance, which enhances the water flow velocity and uniformity. This helps the atomizing head 41 of the nozzle 4 to refine the water flow into uniform small droplets, improving atomization quality and spray uniformity. The funnel-shaped baffle 3 is inverted above the dividing plate 21, and the outlet diameter of the baffle 3 is smaller than the inlet diameter.

[0036] As one possible implementation method, such as Figure 1 , Figure 2 , Figure 6 As shown, the nozzle 4 has a base 42 at its bottom, which is connected to the turbulence chamber 12. The base 42 is provided with a connecting pipe 43, and the inlet of the connecting pipe 43 is connected to the outlet of the turbulence component 3.

[0037] The connecting pipe 43 is a hollow straight pipe structure, serving as a channel for water flow from the baffle 3 to the nozzle 4. The outlet end of the baffle 3 is inserted into the inlet of the connecting pipe 43. The base 42 is an annular fixing component, connected to the inner top of the baffle chamber 12. It reliably connects the nozzle 4 to the baffle chamber 12, ensuring overall sealing and coaxial alignment to prevent leakage and uneven spraying. The base 42 has external threads on its sidewall, and the baffle chamber 12 has internal threads that mate with the external threads of the base 42. The base 42 is threadedly connected to the baffle chamber 12, and PTFE tape is wrapped around the external threads of the base 42 to enhance sealing.

[0038] As one possible implementation method, such as Figure 1 , Figure 6 As shown, multiple atomizing heads 41 are evenly distributed on the top of the nozzle 4.

[0039] The atomizing head 41 is a hollow conical spray hole structure connected to the nozzle 4, arranged in a ring or fan shape. For example, 37 atomizing heads 41 are evenly distributed on the top of the nozzle 4. The atomizing head 41, together with the baffle 3, atomizes the high-speed swirling water flow into fine water droplets, achieving efficient fine mist spraying. The water droplets have a wide distribution range, small particle size, and strong adhesion, reducing evaporation loss, improving irrigation uniformity and water utilization efficiency, and enhancing spray uniformity and water-saving efficiency. Therefore, it is suitable for intelligent water-saving sprinkler irrigation in landscaping scenarios, meeting the current needs of landscaping irrigation for high efficiency and water-saving atomized spraying.

[0040] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
