[0027] The utility model provides a kind of spraying device.

[0028] Refer to Figs. 1-2 The utility model embodiment, a kind of spraying device includes:

[0029] Spraying pipe assembly 10, for being communicated with water source;

[0030] Spraying head assembly 20, including multiple spraying heads 21 being spaced apart in the first direction extension on the spraying pipe assembly 10, each spraying head 21 is communicated with the spraying pipe assembly 10, each spraying head 21 has multiple nozzles 211, and the projection of multiple nozzles 211 in the first direction is staggered arrangement.

[0031] The present solution describes a sprinkling device, in particular an irrigation or cleaning apparatus having a specific structure and function. It comprises two main parts: a sprinkling pipe assembly 10, which is the main conveying pipe of the entire sprinkling system, responsible for introducing the water source to the individual sprinkling heads 21. The sprinkling pipe assembly 10 needs to be connected to an external water source and internally forms a continuous channel that ensures the water flow is evenly distributed to each sprinkling head 21. A sprinkling head assembly 20, which is composed of multiple sprinkling heads 21, arranged at intervals along a so-called "first direction" on the sprinkling pipe assembly 10. Each sprinkling head 21 is in communication with the sprinkling pipe assembly 10 and has multiple nozzles 211. It can be understood that the "first direction" mentioned here refers to the direction in which the sprinkling heads 21 are arranged, and the projection of the nozzles 211 in this direction is staggered, which means that from the top, the nozzle positions of different sprinkling heads are not completely aligned, but there is a certain misalignment. The purpose of this design is to optimize the water distribution pattern, making the spraying more uniform, while reducing the interference between adjacent nozzles 211, thereby improving the effect of irrigation or cleaning. The staggered arrangement of nozzles 211 can ensure that even in limited space, extensive coverage can be achieved, and the problem of water flow conflict or excessive or insufficient overlapping areas caused by nozzles 211 directly opposite each other is avoided. Specifically, the sprinkling pipe assembly 10 is first connected to a water source to ensure that water can flow into the sprinkling pipe assembly 10. The water flow is guided to the individual sprinkling heads 21 through the sprinkling pipe assembly 10. The sprinkling heads 21 are arranged at intervals along the first direction on the sprinkling pipe assembly 10, expanding the coverage of the spraying area. Each sprinkling head 21 has multiple nozzles 211, which are arranged in a staggered manner. When water pressure pushes water through the nozzles, the water will be broken into fine droplets and sprayed at a certain angle, forming a spray.

[0032] With reference Figs. 1-2 In the embodiment of the present application, the sprinkling head 21 comprises a nozzle cover 212, a nozzle connector 213 and a nozzle seat 214 that are in communication with each other. The nozzle seat 214 is provided on the sprinkling pipe assembly 10, and the nozzle seat 214 is provided with a water inlet portion that is in communication with the sprinkling pipe assembly 10. The nozzle connector 213 is connected to the nozzle cover 212 and the nozzle seat 214, and multiple nozzles 211 are provided on the nozzle cover 212.

[0033] Specifically, the nozzle cap 212 is located at the foremost end of the spray head assembly 10 and is responsible for forming water droplets and controlling the spray angle. It typically includes multiple nozzles 211 or a specific shape design to achieve different spray patterns. The nozzle connector 213, as a connecting component, connects the nozzle cap 212 to the nozzle seat 214, ensuring that water flow can be smoothly transmitted from the nozzle seat 214 to the nozzle cap 212 and sprayed out through the nozzles 211 on the nozzle cap 212. The nozzle seat 214 is mounted on the spray pipe assembly 10 and has an internal water inlet that communicates directly with the spray pipe assembly 10, thereby receiving pressurized water from the water source and guiding it to the nozzle connector 213 and the nozzle cap 212. Specifically, the water source reaches the water inlet of each nozzle seat 214 through the spray pipe assembly 10. The water entering the nozzle seat 214 flows to the nozzle connector 213 through its internal structure. The water flow is transmitted to the nozzle cap 212 via the nozzle connector 213 and finally sprayed out through the multiple nozzles 211 on the nozzle cap 212 to create the desired spray effect. The spray head 21 is divided into three parts: a nozzle cover 212, a nozzle connector 213, and a nozzle seat 214. This allows each component to be manufactured, replaced, or repaired independently, reducing maintenance costs and increasing flexibility. By clearly distinguishing components with different functions, the water flow path can be better controlled, reducing water loss and improving spraying efficiency. Users can select different types of nozzle covers 212 according to their actual needs, such as changing the size, shape, or number of nozzles to adapt to different spraying requirements. The multi-stage structure helps filter impurities and reduces the possibility of nozzle clogging, especially in cases of poor water quality. This design can extend the service life of the spray system. Understandably, the nozzle cap 212 can be a fan-shaped nozzle design, with a specially shaped channel inside the nozzle cap 212 that allows the water flow to form a flat fan-shaped distribution when it leaves; it can also be a vortex nozzle design, with a spiral guide vane inside that causes the water flow to form a vortex before spraying out, thereby producing a fine water mist; it can also be an adjustable nozzle design, with the nozzle cap 212 equipped with a knob or other adjustment mechanism that can be rotated to change the size or direction of the nozzle opening, thereby adjusting the spray range and intensity; or it can be an anti-clogging design, with a filter screen or self-cleaning device installed at the inlet of the nozzle cap 212, or a larger nozzle size.

[0034] Reference Figs. 1-2 In this embodiment of the present invention, the nozzle connector 213 includes a nozzle head body 2131 and a nozzle head base 2132. The nozzle head body 2131 is disposed at one end of the nozzle head base 2132, the nozzle seat 214 is installed at the other end of the nozzle head body 2131, and the other end of the nozzle head base 2132 is installed on the nozzle cover 212.

[0035] The structure of the nozzle joint 213 is further refined, which is decomposed into two main parts: the nozzle head body 2131 and the nozzle head base 2132. In addition, the nozzle seat 214 is installed at one end of the nozzle head body 2131, while the other end of the nozzle head base 2132 is connected with the nozzle cover 212. The nozzle head body 2131, which is the main part of the nozzle joint 213, is located at one end of the nozzle head base 2132, and the nozzle seat 214 is installed at the other end. It is responsible for transmitting water from the nozzle head base 2132 to the nozzle seat 214. The nozzle head base 2132, as the base part of the nozzle joint 213, is connected with the nozzle head body 2131 at one end and installed on the nozzle cover 212 at the other end. It plays a supporting role and ensures that the water flow can smoothly enter the nozzle cover. The nozzle seat 214, unlike the nozzle seat 213 described earlier, refers to the component installed on the nozzle head body 2131. It directly communicates with the shower pipe assembly 10, receives pressure water from the water source, and guides the water to the nozzle joint through the internal channel. Specifically, the water first reaches the nozzle seat 214 through the shower pipe assembly. The water flows through the channel inside the nozzle seat to the nozzle head body 2131. The water continues to flow through the nozzle head body 2131 and finally enters the nozzle cover 212 through the nozzle head base 2132. Finally, the water flows out through the multiple nozzles 211 on the nozzle cover 212, forming the desired spray effect. It can be understood that the nozzle head body 2131 can be a streamlined internal cavity design, with the internal channel designed as a smooth streamline; It can also be a rotatable or tiltable design between the nozzle head body 2131 and the nozzle cover 212, allowing users to adjust the spray angle; It can also be a multi-stage pressure reduction design, with a multi-stage pressure reduction valve or similar structure built-in, gradually reducing the water pressure to an appropriate level; It can also be a multi-stage pressure reduction design, with a quick connector, buckle or other form of convenient connection between the nozzle head base 2132. It can be understood that the nozzle head base 2132, as a key component connecting the nozzle cover 212 and the nozzle head body 2131, its structural design is crucial to ensure smooth water flow, good sealing and easy maintenance. The outer side of the nozzle head base 2132 is provided with external threads or internal threads for connection with the nozzle cover 212 and the nozzle head body 2131; It can also be a quick release mechanism using a buckle, spring pin or other form of quick connector, which can be connected or separated without tools; It can also be equipped with O-rings, rubber gaskets and other sealing elements at the end in contact with the nozzle cover 212 to prevent water leakage and prolong the service life. Further, the nozzle head body 2131 and the nozzle head base 2132 can be detachably connected, which can be connected by a buckle or through a quick connector consisting of two cooperating half joints, one with a locking device and the other with a spring pin or other form of locking mechanism; It can also be a flange connection, with each part having a flange with a hole, fixed together by screws or bolts.

[0036] Referring toFigs. 1-2 In the embodiment of the utility model, the spraying head 21 further comprises a first sealing piece 215, which is arranged between the nozzle seat 214 and the nozzle connector 213.

[0037] The first sealing piece 215 is arranged between the nozzle seat 214 and the nozzle connector 213 to play a sealing role and prevent water leakage. It can be understood that the first sealing piece 215 can be in the shape of a circular ring and be installed in a groove between the contact surfaces of two components; it can also be a flat gasket, a flat circular shape or a square shape, and be arranged between two surfaces that need to be sealed; or it can be a composite sealing piece.

[0038] Referring to Figs. 1-2 In the embodiment of the utility model, the spraying head 21 further comprises a second sealing piece 216, which is arranged between the nozzle connector 213 and the nozzle cover 212.

[0039] The second sealing piece 216 is arranged between the nozzle connector 213 and the nozzle cover 212 to play a sealing role and prevent water leakage. It can be understood that the second sealing piece 216 can be in the shape of a circular ring and be installed in a groove between the contact surfaces of two components; it can also be a flat gasket, a flat circular shape or a square shape, and be arranged between two surfaces that need to be sealed; or it can be a composite sealing piece.

[0040] Referring to Figs. 1-2 In the embodiment of the utility model, one side of the nozzle seat 214 is in the shape of an arc, and the arc-shaped surface of the nozzle seat 214 is arranged in close contact with the outer surface of the spraying pipe assembly 10.

[0041] It can be ensured that the nozzle seat 214 can be closely attached to the spraying pipe assembly 10, and the sealing performance and structural stability can be improved by optimizing the shape of the contact surface. Since the arc-shaped surface of the nozzle seat 214 matches the outer surface of the spraying pipe assembly 10, the contact area between the two is larger, and water leakage can be more effectively prevented. The close-fitting design reduces the gaps that may cause leakage. The arc-shaped surface helps to guide the nozzle seat 214 to be correctly installed on the spraying pipe assembly 10, ensuring accurate positioning even without strict alignment tools. The arc-shaped design makes the pressure distribution between the nozzle seat 214 and the spraying pipe assembly 10 more uniform, reducing local stress concentration and thus improving the strength of the overall structure. The close-fitting design increases the rigidity of the system, reducing the risk of loosening caused by vibration or other external forces.

A plurality of spraying heads 21 are installed on each spraying pipe, which are responsible for uniformly spraying water to the designated area. Since there are at least two independent spraying pipes, the spraying heads 21 on each pipe can be controlled individually according to actual needs, realizing zoned water supply. If one pipe has a problem, the other can still work normally, improving the redundancy and reliability of the system. Users can add more spraying pipes as needed to cover a larger area or adjust the spraying pattern. Each spraying pipe serves as a module, facilitating flexible configuration according to specific application scenarios. This design provides a more flexible spraying layout that can adapt to larger or more complex irrigation areas.

[0045] The two spraying pipes are connected into a whole through the connecting piece 30, reducing the need for additional support structures or fixing devices, making the entire system more compact and neat. The presence of the connecting piece 30 increases the mechanical connection strength between the two spraying pipes, preventing displacement or loosening caused by external forces such as wind, vibration, etc. It can be understood that the connecting piece 30 can be a T-shaped or Y-shaped tee joint; it can also be a quick plug-in joint; it can also be a flange connection joint, with each part having a flange with a hole, fixed together by screws or bolts.

[0046] Referring to Figs. 1-2 In the utility model embodiment, the spraying device further comprises a water supply pipe 40 and a water supply pipe support 50, the water supply pipe 40 is used for connecting the water source with the first spraying pipe 11 and the second spraying pipe 12, the water supply pipe 40 is installed on the water supply pipe support 50, and the water supply pipe support 50 is connected to the connecting piece 30.

The water supply pipe support 50 is connected to the connecting piece 30, forming an integral structure. The connecting piece 30 connects the first spray pipe 11 and the second spray pipe 12 together and serves as the fixing point of the water supply pipe support 50. The presence of the water supply pipe support 50 increases the mechanical support of the water supply pipe 40, preventing displacement or loosening caused by external forces such as wind, vibration, etc. By reasonably designing the position and shape of the installation support, the water supply pipe 40 can more evenly share the load when under pressure, avoiding local stress concentration. It can be understood that the water supply pipe 40 can be equipped with a flow regulating device to ensure that each spray pipe obtains the appropriate amount of water, maintaining uniform spraying even in different heights or lengths. It can be understood that the water supply pipe support 50 is provided with a groove or clamp matching the outer diameter of the water supply pipe 40, and the installation can be completed by gently pushing the water supply pipe into the groove of the support; it can also be that the water supply pipe support 50 is provided with a hole, and the water supply pipe 40 is tightly pressed on the support by bolts or screws; it can also be that a metal or plastic clamp is used to tightly press the water supply pipe 40 on the water supply pipe support 50, and a rubber gasket is usually placed between the contact surfaces to ensure sealing.
