[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0024] Example 1 Reference Figure 1 to Figure 7 , which is the first embodiment of the present invention, and this embodiment provides an automatically controlled garden watering device. The automatically controlled garden watering device includes a main component 100, including a delivery pipe 101, a diverter pipe 102, a rotating member 103 and a diverter plate 104. The diverter pipe 102 is arranged on the surface of the delivery pipe 101, the rotating member 103 is located at the end of the diverter pipe 102, and the diverter plate 104 is arranged in the rotating member 103.

[0025] A pulse solenoid valve is arranged on the delivery pipe 101, and an external controller can control the pulse solenoid valve to control whether the delivery pipe 101 delivers water. The water flow can enter the rotating part 103 through the diverter pipe 102. The rotating part 103 is the outer shell of the nozzle, which can drive the diverter disk 104 to rotate. The diverter disk 104 is used to divert the water flow so that the water can be evenly sprayed on the plants. A plurality of diverter pipes 102 are arranged on the surface of the delivery pipe 101.

[0026] The cleaning assembly 200 is arranged in the rotating member 103, including a grinding member 201, which is arranged in the rotating member 103, including a filter disc 201a, a grinding disc 201b, an extrusion disc 201c, a scraper 201d, a connecting shaft 201e and a first spring 201f. The grinding disc 201b is fixed in the filter disc 201a, the extrusion disc 201c is located on one side of the grinding disc 201b, the scraper 201d is rotatably connected to the extrusion disc 201c through the connecting shaft 201e, and the end of the first spring 201f is fixed to one side of the extrusion disc 201c.

[0027] The filter plate 201a is used to filter larger stones and flocs in the water to prevent the larger stones and flocs from clogging the diverter plate 104. The grinding plate 201b is used to cooperate with the extrusion plate 201c, so that the extrusion plate 201c can squeeze the stones on one side of the grinding plate 201b, thereby grinding the stones to reduce the volume of the stones so that the stones will not clog the filter plate 201a and the diverter plate 104. The scraper 201d can cut the flocs on the filter plate 201a so that the flocs are cut off. The connecting shaft 201e is used to support the scraper 201d. The first spring 201f is in a compressed state and is used to push the extrusion plate 201c.

[0028] Specifically, the rotating part 103 includes a nozzle shell 103a, a connecting pipe 103b, a driving blade 103c and a positioning ring 103d. The nozzle shell 103a is rotatably connected to the surface of the diversion pipe 102, the connecting pipe 103b is fixed to the end of the nozzle shell 103a, the driving blade 103c is fixed in the nozzle shell 103a, the positioning ring 103d is fixed to the inner wall of the nozzle shell 103a, and the positioning ring 103d is rotatably connected to the surface of the diversion pipe 102.

[0029] The diverter plate 104 and the filter plate 201a are both fixed in the connecting pipe 103b. When the diverter pipe 102 delivers water to the nozzle housing 103a, the water can push the driving blade 103c, thereby driving the nozzle housing 103a to rotate relative to the diverter pipe 102. The setting of the positioning ring 103d can improve the stability of the connection between the nozzle housing 103a and the diverter pipe 102.

[0030] Specifically, the cleaning assembly 200 also includes a driving member 202, which is arranged in the nozzle housing 103a, including a support rod 202a, a driving column 202b, a positioning block 202c and a protective shell 202d. The support rod 202a is fixed in the diversion pipe 102, the driving column 202b is fixed on one side of the support rod 202a, the positioning block 202c is fixed on the inner wall of the nozzle housing 103a, the driving column 202b is rotatably connected to the positioning block 202c, the protective shell 202d is fixed to the inner wall of the nozzle housing 103a, and the driving column 202b is rotatably connected to the protective shell 202d.

[0031] The support rod 202a is used to fix and support the driving column 202b, the positioning block 202c is used to position the end of the driving column 202b to maintain the stability of the driving column 202b, and the protective shell 202d is used to protect the driving member 202.

[0032] Specifically, the driving member 202 further includes a first bevel gear 202e, a rotating shaft 202f and a second bevel gear 202g. The first bevel gear 202e is fixed to the surface of the driving column 202b. The rotating shaft 202f is rotatably connected to the protective shell 202d. The second bevel gear 202g is fixed to the surface of the rotating shaft 202f.

[0033] The first bevel gear 202e is meshed with the second bevel gear 202g. When the nozzle housing 103a rotates, the rotating shaft 202f can be driven to make a circular motion around the driving column 202b, so that the first bevel gear 202e drives the second bevel gear 202g to rotate, thereby the second bevel gear 202g drives the rotating shaft 202f to rotate.

[0034] Specifically, the driving member 202 further includes a driving gear 202h and a toothed disc 202i. The driving gear 202h is fixed to the surface of the rotating shaft 202f. The toothed disc 202i is located on one side of the driving gear 202h. The driving gear 202h and the toothed disc 202i are meshed. The extrusion disc 201c slides in the toothed disc 202i.

[0035] When the rotating shaft 202f rotates, it can drive the driving gear 202h to rotate, so that the driving gear 202h drives the toothed disc 202i to rotate, so that the toothed disc 202i drives the extrusion disc 201c to rotate, so that the extrusion disc 201c drives the water flow on the side of the filter disc 201a in the nozzle housing 103a to rotate through the scraper 201d, so that the water flow drives the pebbles on one side of the filter disc 201a to move.

[0036] Example 2 Reference Figure 1 to Figure 7 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0037] Specifically, the cleaning component 200 also includes a cleaning piece 203, which is arranged in the filter disc 201a, including a slide rod 203a and a connecting frame 203b. The slide rod 203a slides in the filter disc 201a, and the connecting frame 203b is fixed to the end of the slide rod 203a. The slide rod 203a is provided at both ends of the connecting frame 203b, and the toothed disc 202i is rotatably connected to the surface of the slide rod 203a.

[0038] The connecting frame 203b is used to connect the two sliding rods 203a. The sliding rod 203a is used to support the toothed disc 202i. When the sliding rod 203a moves, it can drive the squeezing disc 201c to approach or move away from the filter disc 201a.

[0039] Specifically, the cleaning component 203 also includes a connecting rod 203c, a second spring 203d, a support arm 203e and a cleaning needle 203f. The connecting rod 203c slides in the sliding rod 203a. The two ends of the second spring 203d are respectively fixed to the inner wall of the connecting rod 203c and the inner wall of the sliding rod 203a. The support arm 203e is fixed to the end of the connecting rod 203c, and the cleaning needle 203f is fixed to one side of the support arm 203e.

[0040] The second spring 203d is in a stretched state, and is used to pull the connecting rod 203c. Through the reset pulling force of the second spring 203d, the connecting rod 203c can be completely retracted into the sliding rod 203a. There are multiple support arms 203e, which are used to support the cleaning needle 203f. The cleaning needle 203f can clean the holes opened on the filter plate 201a, thereby preventing the holes opened on the filter plate 201a from being blocked.

[0041] Specifically, the cleaning part 203 also includes a baffle 203g, a positioning frame 203h and a clearing needle 203i. The baffle 203g is fixed between the support arms 203e, the positioning frame 203h is fixed to one side of the filter plate 201a, the support arm 203e slides in the positioning frame 203h, and the clearing needle 203i is fixed to the other side of the support arm 203e.

[0042] The baffle 203g is used to drive the support arm 203e to move through the impact force of the water flow. The setting of the positioning frame 203h can prevent the support arm 203e from shaking during the movement, so that the cleaning needle 203f and the unblocking needle 203i on both sides of the support arm 203e can move stably.

[0043] Specifically, the through holes formed on the surface of the filter disk 201 a are smaller than the through holes formed on the surface of the diverter disk 104 .

[0044] The through holes on the surface of the filter disc 201a are smaller than the through holes on the surface of the diverter disc 104 , so that the pebbles that pass through the filter disc 201a and enter the connecting pipe 103b will not block the through holes on the surface of the diverter disc 104 .

[0045] Specifically, the number of cleaning needles 203f and unblocking needles 203i is the same, and they correspond one-to-one to the through holes opened on the filter plate 201a and the diverter plate 104.

[0046] The through holes opened on the filter plate 201a and the diverter plate 104 can be cleared by the same number of cleaning needles 203f and unblocking needles 203i to prevent scale from clogging the through holes opened on the filter plate 201a and the diverter plate 104. The cleaning needles 203f and the unblocking needles 203i are much smaller than the through holes opened on the filter plate 201a and the diverter plate 104.

[0047] The present invention has the following beneficial effects: 1. When the water supply of the delivery pipe 101 stops, the through holes in the filter disc 201a can be cleaned to prevent the filter disc 201a from being blocked; 2. During the water delivery process of the delivery pipe 101, when the through hole of the filter plate 201a is blocked, the cleaning needle 203f can clean the through hole of the filter plate 201a to prevent the through hole of the filter plate 201a from being blocked; 3. While the cleaning needle 203f is cleaning the through hole of the filter disc 201a, the dredging needle 203i in the connecting pipe 103b on the other side can clean the through hole of the diverter disc 104 on one side to prevent the through hole of the diverter disc 104 from being blocked by scale; 4. The grinding disc 201b and the squeezing disc 201c cooperate to grind the stones cleaned from the through holes of the filter disc 201a, so that the volume of the stones is gradually reduced, so that they can be discharged smoothly; 5. The flocs blocked on the filter disc 201a can be sheared so that the broken flocs can be discharged with the water flow.

[0048] When in use, the pulse solenoid valve is controlled by an external controller to control the delivery pipe 101 to deliver water. At this time, when the diverter pipe 102 delivers water to the nozzle housing 103a, the water can push the driving blade 103c, thereby driving the nozzle housing 103a to rotate relative to the diverter pipe 102. The water flows through the filter disc 201a into the chamber of the connecting pipe 103b, and can impact the baffle 203g, so that the baffle 203g drives the support arm 203e to move through the impact force of the water flow, thereby moving the cleaning needle 203f out of the through hole of the filter disc 201a.

[0049] When one of the filter discs 201a is clogged by stones, the water flow capacity of the filter disc 201a will be reduced, resulting in a decrease in the flow rate of the water flow in the connecting pipe 103b, which reduces the impact force of the water flow on the baffle 203g, so that the baffles 203g in the two connecting pipes 103b are subjected to different impact forces of the water flow. The baffle 203g in the other connecting pipe 103b will pull the support arm 203e on the side of the filter disc 201a clogged with stones through the sliding rod 203a and the connecting frame 203b, so that the support arm 203e drives multiple cleaning needles 203f to clean the filter disc. The stones in 201a are pushed to push the blocked stones out of the filter plate 201a. The rotation of the squeezing plate 201c can drive the scraper 201d to rotate, so that the scraper 201d stirs the water flow on one side of the filter plate 201a, so that the water flow drives the small stones originally blocked in the through holes of the filter plate 201a to move, so that the small stones have a probability of entering between the grinding plate 201b and the squeezing plate 201c, thereby grinding the stones, making the volume of the stones gradually reduce until they can pass through the through holes of the filter plate 201a and then be discharged from the through holes of the diverter plate 104.

[0050] When the filter plate 201a is clogged with stones, causing the cleaning needle 203f to be inserted into the through hole of the filter plate 201a, the support arm 203e in the other connecting tube 103b will drive the clearing needle 203i to be inserted into the through hole of the diverter plate 104, thereby cleaning the through hole of the diverter plate 104 and preventing the through hole of the diverter plate 104 from being clogged with scale.

[0051] While the squeezing disc 201c drives the scraper 201d to rotate, the scraper 201d can cut the flocs on the filter disc 201a, so that the flocs are cut off. The situation where the flocs are blocked on the filter disc 201a is generally that the two ends of the flocs are respectively inserted into the two through holes of the filter disc 201a. At this time, the flocs are squeezed on the surface of the filter disc 201a by the water flow. When the scraper 201d passes through the through holes of the filter disc 201a where the flocs are inserted, it can cooperate with the through holes of the filter disc 201a to form a certain shear force, thereby cutting the flocs, so that the flocs enter the connecting pipe 103b under the impact of the water flow, and then are discharged from the diverter disc 104.

[0052] When the delivery pipe 101 stops delivering water, the connecting rod 203c can be completely retracted into the sliding rod 203a under the action of the reset tension of the second spring 203d. At this time, the connecting rod 203c can drive the supporting arm 203e to move toward the filter plate 201a, so that the cleaning needle 203f is inserted into the through hole of the filter plate 201a to clean the through hole of the filter plate 201a to prevent the filter plate 201a from being blocked by stones or scale.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
