[0001] The invention relates to the technical field of garden maintenance, in particular to a spraying device. Background Art

[0002] Spraying devices are commonly used by garden maintenance personnel in daily garden maintenance. They are mainly used to spray liquids such as water, liquid pesticides and liquid fertilizers onto plants in the garden to ensure the normal growth of plants in the garden.

[0003] Traditional spraying devices mainly include fixed spraying devices and rotary spraying devices. In the fixed spraying device, the direction of liquid spraying is fixed, so the area covered by the liquid sprayed during use is limited, and multiple fixed spraying devices are often required to meet the use requirements. The rotary spraying device uses rotation to spray liquid along its circumference. Although this can increase the area covered by the sprayed liquid, it will also cause the position that does not need to be sprayed to be sprayed, thereby causing a waste of resources.

[0016] Further, the driving part can rotate together with the shell, and when the driving part contacts the stop part, the driving part can cooperate with the stop part and drive the shell to move from the first station to the second station or from the second station to the first station.

[0017] Further, the driving part includes a rotating base mounted on the liquid supply pipe and connected to the shell, and a lever component rotatably mounted on the rotating base and connected to the shell, the lever component includes a first lever and a second lever connected to the first lever at a certain angle, the end of the second lever away from the first lever can cooperate with the slide groove structure provided on the shell, and the stop part is a first lever component and a second lever component rotatably mounted on the liquid supply pipe, when the first lever contacts the first lever component, the first lever component can force the first lever to drive the second lever to rotate, so as to drive the shell to move from the first station to the second station, and when the first lever contacts the second lever component, the second lever component can force the first lever to drive the second lever to rotate, so as to drive the shell to move from the second station to the first station.

[0019] Furthermore, the spray device also includes a water-blocking paddle rotatably connected to the shell, for shielding the liquid sprayed out through the nozzle.

[0020] Furthermore, the spray device also includes a blocking component which is sleeved on the liquid supply pipe and located on both sides of the shell, and is used to prevent the spray head component from detaching from the liquid supply pipe.

DETAILED DESCRIPTION

[0031] The object of the present invention is to provide a spraying device which can not only increase the area covered by the liquid sprayed by the spraying device, but also avoid waste of resources, and the spraying device has a simple structure, which can reduce the production cost and use cost of the spraying device.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Please refer to Figures 1 to 4 , Figure 1 is a schematic structural diagram of a spraying device according to an embodiment of the present invention; Figure 2 is a cross-sectional view of a spraying device according to an embodiment of the present invention; Figure 3 It is a schematic structural diagram of the housing of the spraying device according to an embodiment of the present invention when it is in the first working position; Figure 4 It is a schematic structural diagram of the shell of the spraying device according to an embodiment of the present invention when it is in the second working position.

[0034] In a specific embodiment, the present invention provides a spraying device, which includes a liquid supply pipe 1, a spray head component 2 and a drive assembly 3. One end of the liquid supply pipe 1 is provided with a liquid inlet 11 for connecting to the liquid supply device, and the side wall of the other end of the liquid supply pipe 1 is provided with a lower liquid outlet 12, and an upper liquid outlet 13 spaced from the lower liquid outlet 12 and located on the side of the lower liquid outlet 12 away from the liquid inlet 11. The spray head component 2 includes a shell 21 which is sleeved on one end of the liquid supply pipe 1 provided with the lower liquid outlet 12 and the upper liquid outlet 13 and has a first station and a second station, and a nozzle 22 arranged on the shell 21, and the drive assembly 3 is connected to the shell 21.

[0035] When the shell 21 is in the first station, it can be driven by the liquid sprayed through the lower liquid outlet 12 to rotate clockwise or counterclockwise, and can be driven by the driving component 3 to move from the first station to the second station; when the shell 21 is in the second station, it can be driven by the liquid sprayed through the upper liquid outlet 13 to rotate counterclockwise or clockwise, and can be driven by the driving component 3 to move from the second station to the first station. It should be noted that the rotation direction of the shell 21 when it is in the first station is opposite to the rotation direction when it is in the second station. Specifically, when the shell 21 in the first station is driven to rotate clockwise, the shell 21 in the second station is driven to rotate counterclockwise; when the shell 21 in the first station is driven to rotate counterclockwise, the shell 21 in the second station is driven to rotate clockwise.

[0036] The following describes the working process of the spraying device in detail by taking the initial position of the housing 21 of the spraying device at the first working position as an example:

[0037] The high-pressure liquid provided by the liquid supply device enters the liquid supply pipe 1 through the liquid inlet 11 and is ejected through the lower liquid outlet 12. The ejected liquid drives the shell 21 to rotate clockwise. When the shell 21 rotates, the driving part 31 drives the shell 21 to move from the first station to the second station. At this time, the liquid ejected through the upper liquid outlet 13 drives the shell 21 to rotate counterclockwise. When the shell 21 rotates, the driving part 31 drives the shell 21 to move from the second station to the first station. This cycle is repeated until the spraying of the liquid is completed.

[0038] Alternatively, the high-pressure liquid provided by the liquid supply device enters the liquid supply pipe 1 through the liquid inlet 11 and is ejected through the lower liquid outlet 12. The ejected liquid drives the shell 21 to rotate counterclockwise. When the shell 21 rotates, the driving part 31 drives the shell 21 to move from the first station to the second station. At this time, the liquid ejected through the upper liquid outlet 13 drives the shell 21 to rotate clockwise. When the shell 21 rotates, the driving part 31 drives the shell 21 to move from the second station to the first station. This cycle is repeated until the spraying of the liquid is completed.

[0039] According to the spraying device of the present embodiment, the spraying device comprises a liquid supply pipe 1, a spray head component 2 and a driving assembly 3. A lower liquid outlet hole 12 and an upper liquid outlet hole 13 are provided on one end of the liquid supply pipe 1. The shell 21 of the spray head component 2 is sleeved on one end of the liquid supply pipe 1 provided with the lower liquid outlet hole 12 and the upper liquid outlet hole 13, and has a first station and a second station. First, the spraying device drives the shell 21 to rotate by the impact force of the liquid sprayed through the liquid outlet hole, thereby increasing the area covered by the liquid sprayed by the spraying device. Secondly, the driving assembly 3 can drive the shell 21 to move from the first station to the second station or from the second station to the first station. Since the first station and the second station correspond to the lower liquid outlet hole 12 and the upper liquid outlet hole 13 respectively, and the lower liquid outlet hole 12 and the upper liquid outlet hole 13 drive the shell 21 to rotate in opposite directions, the rotation direction of the shell 21 can be switched, so that the spraying device can only spray in the position where the liquid needs to be sprayed, thereby avoiding the waste of resources. Moreover, using different workstations corresponding to different liquid outlets to change the rotation direction can also simplify the structure of the spray device, reduce the difficulty of maintaining the spray device, and thus reduce the production cost and use cost of the spray device. In summary, the spray device can not only increase the area covered by the liquid sprayed by the spray device, but also avoid waste of resources, and the spray device has a simple structure, which can reduce the production cost and use cost of the spray device.

[0040] In the above specific embodiment, the center lines of the lower liquid outlet 12 and the upper liquid outlet 13 do not intersect with the axial center line of the liquid supply pipe 1, and the shell 21 includes a shell body 211 having a liquid holding chamber, a lower protrusion 212 connected to the outer wall of the lower bottom plate of the shell body 211, and an upper protrusion 213 connected to the outer wall of the upper bottom plate of the shell body 211. When the shell 21 is in the first working position, the lower liquid outlet 12 can be exposed in the liquid holding chamber and the upper liquid outlet 13 can be blocked by the shell body 211 and / or the upper protrusion 213. When the shell 21 is in the second working position, the upper liquid outlet 13 can be exposed in the liquid holding chamber and the lower liquid outlet 12 can be blocked by the shell body 211 and / or the lower protrusion 212.

[0041] Specifically, when the shell 21 is in the first working position, the upper liquid outlet 13 is blocked by the shell body 211 and / or the upper protrusion 213, and only the liquid sprayed through the lower liquid outlet 12 can enter the liquid containing chamber of the shell body 211, and the liquid sprayed into the liquid containing chamber forces the shell 21 to rotate by impacting the side wall of the shell body 211 or causing the liquid in the liquid containing chamber to rotate; when the shell 21 is in the second working position, the lower liquid outlet 12 is blocked by the shell body 211 and / or the lower protrusion 212, and only the liquid sprayed through the upper liquid outlet 13 can enter the liquid containing chamber of the shell body 211, and the liquid sprayed into the liquid containing chamber forces the shell 21 to rotate by impacting the side wall of the shell body 211 or causing the liquid in the liquid containing chamber to rotate.

[0042] On the basis of the above specific embodiment, the spraying device further comprises a first rib plate 4 provided on the inner wall of the lower bottom plate of the housing 21 and a second rib plate 5 provided on the inner wall of the upper bottom plate of the housing 21. When the housing 21 is in the first position, the liquid sprayed from the lower liquid outlet 12 can hit the first rib plate 4 to drive the housing 21 to rotate; when the housing 21 is in the second position, the liquid sprayed from the upper liquid outlet 13 can hit the second rib plate 5 to drive the housing 21 to rotate. Providing the rib plates and allowing the liquid sprayed from the liquid outlet holes to hit the rib plates can ensure that the housing 21 can rotate smoothly and continuously during the use of the spraying device, which can avoid the situation where the housing 21 cannot be driven to rotate due to insufficient liquid pressure or the like.

[0043] In the above specific embodiments, there is no specific limitation on the structure and shape of the first rib 4 and the second rib 5, as long as they can drive the housing 21 to rotate under the impact of the liquid sprayed through the liquid outlet. However, in a specific embodiment, the first rib 4 and the second rib 5 are preferably arc-shaped, and the liquid sprayed from the lower liquid outlet 12 can hit the concave side of the first rib 4, and the liquid sprayed from the upper liquid outlet 13 can hit the concave side of the second rib 5. This structure can increase the area where the liquid sprayed from the liquid outlet can contact the ribs, thereby further ensuring that the housing 21 can rotate smoothly and continuously during the use of the spraying device.

[0044] In the above specific embodiment, the number of the lower liquid outlet holes 12 and the upper liquid outlet holes 13 are both three, and the number of the first ribs 4 and the second ribs 5 are both four, thereby ensuring that at least one rib is opposite to the liquid outlet hole during the rotation of the shell 21, and further ensuring that the shell 21 can rotate smoothly and continuously during the use of the spray device. It should be noted that in other embodiments, those skilled in the art can select the number of the lower liquid outlet holes 12 and the upper liquid outlet holes 13, as well as the number of the first ribs 4 and the second ribs 5 according to their needs, and no further description is given here.

[0045] On the basis of the above specific implementation, the driving assembly 3 includes a driving part 31 connected to the shell 21 and a stopper 32 connected to the liquid supply pipe 1. The driving part 31 can rotate with the shell 21, and when the driving part 31 contacts the stopper 32, the driving part 31 can cooperate with the stopper 32 and drive the shell 21 to move from the first station to the second station or from the second station to the first station. First of all, this structure enables garden maintenance personnel to adjust the rotation angle of the shell 21 according to the requirements of the spraying area, thereby improving the applicability of the spraying device. At the same time, this structure can complete the action of driving the shell 21 to move only by the kinetic energy brought by the rotation of the shell 21, thereby avoiding the increase of power consumption due to the use of motor drive, and further avoiding the waste of resources.

[0046] On the basis of the above specific implementation manner, the driving part 31 includes a rotating base 311 which is sleeved on the liquid supply pipe 1 and connected to the shell 21, and a lever component 312 which is rotatably provided on the rotating base 311 and connected to the shell 21, the lever component 312 includes a first lever 3121 and a second lever 3122 which is connected to the first lever 3121 at a certain angle, wherein preferably, an angle between the first lever 3121 and the second lever 3122 is greater than 90° and less than or equal to 180°, and an end of the second lever 3122 away from the first lever 3121 can cooperate with a slide groove structure provided on the shell 21. The stopper 32 is a first stopper component 321 and a second stopper component 322 rotatably mounted on the liquid supply pipe 1. When the first lever 3121 rotating with the housing 21 at the first station contacts the first stopper component 321, the first stopper component 321 can force the first stopper component 3121 to rotate and drive the second stopper component 3122 to rotate, so as to drive the housing 21 to move from the first station to the second station. When the first lever 3121 rotating with the housing 21 at the second station contacts the second stopper component 322, the second stopper component 322 can force the first stopper component 3121 to rotate and drive the second stopper component 3122 to rotate, so as to drive the housing 21 to move from the second station to the first station. The two stopper components rotatably mounted on the liquid supply pipe 1 allow the garden maintenance personnel to adjust the rotation angle of the housing 21 according to the requirements of the spraying area, etc., thereby improving the applicability of the spraying device.

[0047] In the above specific implementation, those skilled in the art can select the connection method between the rotating base 311 and the housing 21 according to their needs, as long as it can ensure that the rotating base 311 can rotate with the housing 21 and the housing 21 can reciprocate between the first station and the second station. However, in a specific embodiment, the connection method between the rotating base 311 and the housing 21 is preferably a bolt 3111 and a socket 3112 that are easy to process. Specifically, when the bolt 3111 is provided on the rotating base 311, the socket 3112 is provided on the housing 21, or when the socket 3112 is provided on the rotating base 311, the bolt 3111 is provided on the housing 21, or when the bolt 3111 and the socket 3112 are provided on the rotating base 311 at the same time, the socket 3112 and the bolt 3111 that match them are also provided on the housing 21 at the same time. Among them, the length of the pin 3111 is greater than the moving distance of the shell 21 from the first station to the second station, thereby ensuring that the rotating base 311 can always rotate with the shell 21, and avoiding the situation where the spraying device cannot be used normally due to the separation of the shell 21 and the rotating base 311.

[0048] Based on any one of the above-mentioned specific embodiments, the spraying device also includes a water-blocking paddle 6 rotatably connected to the shell 21, which is used to block the liquid sprayed through the nozzle 22. When the water-blocking paddle 6 is moved to the outlet of the nozzle 22, it can disperse the liquid sprayed through the nozzle 22 into a mist, thereby making the liquid spray more even.

[0049] Based on any of the above-mentioned specific embodiments, the spray device also includes a blocking component 7 which is sleeved on the liquid supply pipe 1 and located on both sides of the shell 21, and is used to prevent the nozzle component 2 from detaching from the liquid supply pipe 1. By setting the blocking component 7, the movable position of the shell 21 on the liquid supply pipe 1 can be limited, thereby avoiding the situation where the spray device cannot be used normally due to the shell 21 detaching from the liquid supply pipe 1.

[0050] Based on any of the above-mentioned specific embodiments, the spraying device also includes a first sealing ring 8 which is mounted on the liquid supply pipe 1 and is used to prevent the liquid from flowing out from between the liquid supply pipe 1 and the lower protrusion 212, thereby preventing the liquid from flowing out from between the lower protrusion 212 and the liquid supply pipe 1, thereby further avoiding the waste of resources.

[0051] Based on any of the above-mentioned specific embodiments, the spray device also includes a pressure cap 9 connected to the upper protrusion 213, and a second sealing ring 10 is provided between the pressure cap 9 and the upper protrusion 213. The pressure cap 9 can not only prevent the liquid from flowing out from between the upper protrusion 213 and the liquid supply pipe 1 to avoid waste of resources, but also prevent the spray device from being unable to be used normally due to the shell 21 being detached from the liquid supply pipe 1.

[0052] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
