Description

Technical Field

[0001] The utility model belongs to the technical field of water spraying sprinklers, in particular to a multifunctional sprinkler for gardening. Background Art

[0002] Shower heads are also called shower heads. Some shower heads are used for showering and washing, while others are used for watering flowers, potted plants and other plants. Currently, shower heads can achieve different water output sizes by rotating their sprinkler covers.

[0003] Currently, some gardens are often planted with different types of flowers and shrubs, each requiring different watering methods. For example, some valuable flowers and plants or flowering plants require misting, some shrubs and grasses require large or small areas of watering, and some bonsai require watering without splashing. Gardens also require regular flushing and cleaning. However, there are currently no gardening sprinklers that can achieve these multifunctional functions. Summary of the Invention

[0004] In order to solve the deficiencies in the prior art, a multifunctional gardening shower head is provided which has multiple watering modes to meet different watering needs.

[0005] The utility model is realized by the following technical solutions: a multifunctional gardening shower head, comprising a water-discharging water-discharging cover fixed with a water distribution plate, the water distribution plate being rotatably connected to a shower gun body, and a water outlet being eccentrically provided at the end of the shower gun body; the water-discharging cover comprises, in radial order from the inside to the outside, a middle water-discharging area, a first annular water-discharging area, a second annular water-discharging area, and a third annular water-discharging area; the middle water-discharging area is provided with a bubbler, the first annular water-discharging area is provided with water outlet holes of at least two different hole types, and the second annular water-discharging area is provided with an atomizing hole , the third annular water sprinkling area is densely covered with small-aperture water holes; the water inlet cavities of the middle water sprinkling area, the first annular water sprinkling area, the second annular water sprinkling area and the third annular water sprinkling area are all evenly spaced along the circumferential direction within the first annular water sprinkling area, and the middle water sprinkling area, the second annular water sprinkling area and the third annular water sprinkling area are all provided with radial channels extending radially into the first annular area and connected with their own water inlet cavities; the water distribution plate is provided with water inlets corresponding to the water inlet cavities one by one; when the water sprinkling cover drives the water distribution plate to rotate, different water outlet modes of the shower can be selectively switched.

[0006] During use, the user can rotate the sprinkler cover to rotate the water distribution plate at the end of the shower gun body. Since the water outlet of the shower gun body is eccentrically set, the water outlet can be made to correspond to the water inlet of the water distribution plate, so that the water flows into different water inlet chambers, thereby realizing different shower water outlet modes. For example, when bonsai needs to be watered without splashing, water is discharged from the middle sprinkler area, which has a bubbler, so that the water flowing out is in the form of foam and not easy to splash; when precious flowers or plants in the flowering period need to be watered, water is switched to the second annular sprinkler area. The second annular sprinkler area has atomization holes, so the water sprayed out is in the form of water mist; when large-area or general irrigation is required, water can be switched to the third annular sprinkler area. Since the area of ​​the third annular sprinkler area is located at the outermost side, it has the largest area and a large number of small-aperture water holes, so large-area irrigation can be achieved without too large a water flow intensity; when it is necessary to wash the courtyard or water tall trees or high-altitude bonsai, water can be switched to a certain water hole in the first annular sprinkler area.

[0007] Among them, the bubbler is a component that can be matched with any existing water outlet to achieve the water flow combined with a large amount of air to flow out in the form of fine bubbles.

[0008] The atomization hole may be any existing small hole that can realize water atomization.

[0009] Among them, each water outlet in the first sprinkler area corresponds to its own water inlet cavity. The aperture of the water outlet holes in the first sprinkler area is larger than that of the second sprinkler area and the third sprinkler area. The water flow is more concentrated, so it can be used to wash the courtyard or tall trees or high-altitude bonsai.

[0010] The shower gun body is a shower handle that can be held by a user, and a water flow channel is provided inside the shower gun body to communicate with the water outlet.

[0011] Through the setting of the above solution, it is possible to switch between multiple functions, and a variety of different watering modes can be achieved through one shower head, which is more versatile.

[0012] Preferably, the number of the atomization holes is at least six and they are evenly distributed circumferentially in the second annular water sprinkling area. Each of the atomization holes is equipped with an atomization core. The atomization core is cylindrical as a whole, and at least two spiral rotating channels are provided on the circumferential outer wall. The atomization hole and the inner cavity of the second annular water sprinkling area are connected through the rotating channels.

[0013] Through the rotating channel of the atomizer core, when the water flows out of the atomizer hole, it will be accelerated in the rotating channel. While the water flow becomes faster, it also has a centrifugal effect, thereby achieving the atomization effect.

[0014] Preferably, the inner cavity of the atomization hole is conical, and the inner diameter gradually decreases from the inside to the outside.

[0015] This arrangement of the inner cavity can further facilitate the acceleration of the water flow when it exits the atomization hole, thereby achieving an atomization effect.

[0016] Preferably, the inner cavity of the second annular water sprinkling area includes a first inner cavity and a second inner cavity which are arc-shaped and connected to each other, the first inner cavity and the second inner cavity are symmetrically arranged, and a diverter is provided between the first inner cavity and the second inner cavity, and the diverter extends toward the radial channel side of the second annular water sprinkling area.

[0017] The radial channel of the second annular water sprinkling area can be split by the splitter when flowing into the inner cavity of the second annular water sprinkling area, thereby ensuring that each atomizing hole can emit mist at the same time when the water is atomized.

[0018] Preferably, the first inner cavity and the second inner cavity are both provided with a plurality of positioning holes corresponding to the atomizer cores one by one, and the ends of the atomizer cores facing away from the rotating channel are inserted into the positioning holes, and the atomizer cores in the first inner cavity and the atomizer cores in the second inner cavity are both connected by arc-shaped connecting strips.

[0019] By inserting the atomizer core into the positioning hole, a positioning effect can be achieved to prevent the atomizer core from shifting due to excessive water flow. At the same time, an arc-shaped connecting strip is provided to connect the atomizer core to prevent the atomizer core from rotating and moving, thereby ensuring the stability of the atomizer core.

[0020] Preferably, the third annular water sprinkling area includes a hollow and annular third inner cavity and an annular cover plate that covers the third inner cavity. The annular cover plate is provided with a number of V-shaped water outlet parts evenly spaced, and two adjacent V-shaped parts are arranged in opposite directions. The end point of each V-shaped part is provided with the small-aperture water outlet hole, and the inner cavity of the small-aperture water outlet hole is conical, and the inner diameter gradually decreases from the inside to the outside.

[0021] By arranging two adjacent V-shaped pieces in opposite directions, all small-aperture water outlets have two inner and outer circles along the circumferential direction, thereby expanding the irrigation area. The inner cavity of the small-aperture water outlet is conical, which accelerates the outflow of water.

[0022] Preferably, five water outlet holes of different shapes are provided in the first annular water sprinkling area, including an elliptical hole shape, a colander hole shape, a circular hole shape, a spline hole shape and an umbrella hole shape.

[0023] Different water outlet hole shapes can be used for irrigation in different scenarios.

[0024] Preferably, the openings of the water inlets corresponding to the water outlet holes of the first annular water sprinkling area are provided with a blocking member extending into the water inlet cavity, and the blocking member is provided with a blocking portion extending radially inward, and the blocking portion is used to slow down the water flow speed of the water inlet.

[0025] By providing the blocking member and the blocking portion, it is prevented that water from the water outlet holes in the first annular water sprinkling area flows out too quickly.

[0026] Preferably, the water diversion tray is provided with a plurality of recessed snap-in grooves, which correspond one-to-one to the water inlet and are located radially outside the water inlet. The end of the shower gun body is provided with a receiving groove which opens to the side of the water diversion tray, and an elastically retractable snap-in protrusion is provided in the receiving groove, and the snap-in protrusion can extend into the snap-in groove.

[0027] The engagement of the engaging groove and the engaging protrusion completes the engagement of each water outlet mode.

[0028] Preferably, the shower gun body is provided with a water flow channel connected to the water outlet, and the shower cavity is provided with a hinge hole running through it in the thickness direction, the water flow channel flows through the hinge hole, a plug body is rotatably connected in the hinge hole, the plug body and the hinge hole are dynamically sealed, and rotating the plug body can control the opening and closing of the water flow channel and the size of the water flow.

DETAILED DESCRIPTION

[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] like Figures 1 to 3 As shown, this embodiment discloses a multifunctional gardening showerhead, comprising a water-dispensing sprinkler cover 1. The sprinkler cover 1 is secured to a water distribution tray 2, which is ultrasonically welded to the water distribution tray 2. The water distribution tray 2 is rotatably connected to a showerhead lance 3, with a dynamic seal provided therebetween. The showerhead lance 3 has a water flow channel 31 extending along the body of the showerhead 3. An outlet 32, which communicates with the water flow channel 31, is eccentrically positioned at the end where the showerhead 3 connects to the water distribution tray 2. A hinge hole 35 extending through the thickness of the showerhead lance 3 is provided at a turning point. The water flow channel 31 flows through the hinge hole 35. A plug 41 is rotatably connected to the hinge hole 35, with a dynamic seal provided therebetween. The plug 41 has a semi-cylindrical middle section. A rotating handle 42 is provided on the outside of the showerhead lance 3 to engage with the plug 41 to enable the user to rotate the plug 41. Rotating the handle 42 causes the plug body 41 to rotate, thereby controlling the water flow rate of the water flow channel 31 .

[0043] like Figure 2 、 Figure 3 、 Figure 7 and Figure 8As shown, the end of the water distribution plate 2 facing the shower gun body 3 is provided with eight water inlets 21 evenly spaced along a circular path.

The snap-in protrusion 33 is designed to snap into the snap-in groove 23, aligning the water outlet 32 ​​with one of the water inlets 21.

[0044] like Figures 4 to 8 As shown, the sprinkler cover 1 includes a middle sprinkler area 5, a first annular sprinkler area 51, a second annular sprinkler area 52 and a third annular sprinkler area 53 from the inside to the outside in the radial direction; the middle sprinkler area 5 is circular, the first annular sprinkler area 51 is enclosed on the outside of the middle sprinkler area 5, the second annular sprinkler area 52 is enclosed on the outside of the first annular sprinkler area 51, and the third annular sprinkler area 53 is enclosed on the outside of the second annular sprinkler area 52.

[0045] The water inlet cavities 6 of the middle sprinkler area 5, the first annular sprinkler area 51, the second annular sprinkler area 52, and the third annular sprinkler area 53 are all evenly spaced along the circumference within the first annular sprinkler area 51. Each of the middle sprinkler area 5, the second annular sprinkler area 52, and the third annular sprinkler area 53 is provided with a radial channel 61 extending radially into the first annular sprinkler area 51 and communicating with its own water inlet cavities 6. The eight water inlets 21 on the water distribution plate 2 correspond one-to-one with the water inlet cavities 6. When the sprinkler cover 1 rotates the water distribution plate 2, different water discharge modes of the shower can be selectively switched. Five of the eight water inlets 21 are provided with retaining members 24 extending into the water inlet cavities 6 at their openings. These five water inlets 21 serve as water outlets for the first annular sprinkler area 51. The retaining members 24 have a radially inwardly extending retaining portion that is used to slow the water flow from the water inlets 21.

[0046] A bubbler 8 is provided in the middle water sprinkling area. The bubbler 8 is provided with a plurality of mesh holes to allow air to mix in and make water flow out in a bubble shape.

[0047] The first annular watering area 51 is provided with five different types of water outlet holes, including a first water outlet 511, a second water outlet 512, a third water outlet 513, a fourth water outlet 514, and a fifth water outlet 515. The first water outlet 511 has an elliptical shape; the second water outlet 512 has an umbrella shape, and a stopper 5121 is provided at the opening of the second water outlet 512, so that water flows out from both sides of the stopper 5121. Since the opening of the second water outlet 512 is an inverted cone, the water sprayed out has an umbrella shape; the third water outlet 513 has a spline shape, the fourth water outlet 514 has a circular shape, and the fifth water outlet 515 has a colander shape.

[0048] The first water hole 511 is used for cleaning the courtyard, the second water hole 512 is used for large-area watering of bushes and grass, the third water hole 513 and the fourth water hole 514 are used for cleaning tall trees, high-altitude bonsai and courtyards, and the fifth water hole 515 is used for small-area watering of bushes and grass.

[0049] like Figures 4 to 9 As shown, the second annular water sprinkling area 52 is provided with six atomizing holes 521 arranged in an annular manner and evenly spaced. Each atomizing hole 521 is equipped with an atomizing core 7. The atomizing core 7 is cylindrical in shape as a whole, and at least two spiral rotating channels 72 are provided on the circumferential outer wall. The rotating channels 72 are used to connect the atomizing holes 521 and the inner cavity 523 of the second annular water sprinkling area. The inner cavity 523 of the second annular water sprinkling area is respectively an arc-shaped first inner cavity and a second inner cavity that are interconnected. The atomizing cores 7 in the first inner cavity and the atomizing cores 7 in the second inner cavity are connected by an arc-shaped connecting strip 71. Six positioning holes 73 corresponding to the atomizing cores 7 are provided on the water distribution plate 2. The end of the atomizing core 7 facing away from the rotating channel 72 is inserted into the positioning hole 73. The inner cavity of the atomizing hole 521 is conical, and the inner diameter gradually decreases from the inside to the outside. A diverter 522 is provided at the connection between the first inner cavity and the second inner cavity. The diverter 522 extends toward the radial channel 61 side of the second annular water sprinkling area 52 .

[0050] like Figures 4 to 9 As shown, the third annular water sprinkling area 53 is densely covered with small-aperture water outlet holes 532. The third annular water sprinkling area 53 includes a hollow and annular third inner cavity 533 and an annular cover plate covering the third inner cavity 533. The annular cover plate is provided with a plurality of evenly spaced V-shaped members 531. The two adjacent V-shaped members 531 are arranged in opposite directions. A small-aperture water outlet hole 532 is provided at the end point of each V-shaped member 531, that is, each V-shaped member 531 has three small-aperture water outlet holes 532. The inner cavity of the small-aperture water outlet hole 532 is conical, and the inner diameter gradually decreases from the inside to the outside.

[0051] During use, the user can rotate the water distribution plate 2 at the end of the shower gun body 3 by rotating the water cover 1, so that the water flows into different water inlet chambers 6, thereby achieving different shower water discharge modes.

[0052] For example, when the bonsai needs to be watered without splashing, water is released from the middle watering area 5 , which is provided with a bubbler 8 , so that the water flowing out is in a foamy form and is not easy to splash.

[0053] When it is necessary to water valuable flowers or plants in the flowering period, the second annular watering area 52 is switched to discharge water. The second annular watering area 52 has atomizing holes 521, so the water sprayed out is in the form of mist.

[0054] When large-scale or general irrigation is required, water can be supplied from the third annular sprinkling zone 53. Because the third annular sprinkling zone 53 is located on the outermost side and has the largest area, and contains a large number of small-diameter water outlet holes 532, it can irrigate a large area without excessive water flow. Alternatively, the second water outlet holes 512 can be used.

[0055] When it is necessary to flush the courtyard or water tall trees or high-altitude bonsai, the fourth water outlet 514 and the fifth water outlet 515 can be switched to.

[0056] When the courtyard needs to be flushed, the first water outlet 511 can be used.
