DETAILED DESCRIPTION OF THE INVENTION

[0021] For a clearer understanding of the purposes, technical schemes and advantages of the invention, a further detailed description of the invention is given with the accompanying drawings and embodiments as follows. It should be understood that the specific embodiment in the following description is only used for explaining the invention instead of being used for limiting the invention.

[0022] As is shown in FIG. 1, a multifunctional infrared induction water sprinkler comprises a water inlet pipe 10, and the water inlet pipe 10 is connected with an infrared induction control device 20 and a water outlet device 30; all objects can emit infrared rays, and the higher the temperature is, the higher the intensity of infrared rays is; the infrared induction control device 20 receives mobile infrared rays through an infrared pyroelectric probe so as to judge whether an object is an animal or not, intelligent recognition is conducted when the probe induces mobile infrared rays or variable strong-weak infrared rays, and if the object is an animal, the water outlet device 30 is controlled to spray out water mist to repel the animal; the water outlet device 30 is connected with the infrared induction control device 20 through a universal joint 301, as is shown in FIG. 3, the universal joint 301 is a movable joint and can rotate freely, and thus a sprinkler head 303 can be adjusted by a large elevation angle; the horizontal angle and the sprinkling direction of a sprinkler nozzle 304 can be adjusted through a sprinkling angle regulator 302 located at the upper end of the universal joint and connected with the sprinkler head 303, and thus water mist can be sprinkled at any angle; when animals in the distance or nearby are repelled and water needs to be sprayed at a special angle, the required spraying effect can be achieved by adjusting the universal joint, so that actual requirements are met, and animals can be effectively repelled.

[0023] Specifically, as is shown in FIG. 1 and FIG. 2, the infrared induction control device 20 comprises the infrared pyroelectric probe, a pre-amplifier, a central processing unit, an electromagnetic valve actuator and an electromagnetic valve which are arranged in sequence. As is shown in FIG. 1, the infrared induction control device 20 is located in a shell which is of a spherical structure and is composed of an upper cover 21 and a lower cover 22, an infrared induction window 201 is arranged on the interface of the upper cover 21 and the lower cover 22 and located on the lower cover 22, and the infrared pyroelectric probe is located in the infrared induction window 201; the lower cover 22 is provided with a screw hole 23 used for fixing the upper cover 21 and the lower cover 22 together, and a supply hub 24. When the water sprinkler operates, the infrared pyroelectric probe detects infrared rays emitted by animals through the infrared induction window 201, then an infrared ray signal is amplified through the pre-amplifier and sent to the central processing unit, whether the infrared probe is triggered by animals or not is intelligently identified, and if the infrared probe is triggered by animals, an electromagnet valve control signal is output, the electromagnetic valve is opened to spray out water mist, and thus animals are repelled.

[0024] Furthermore, the infrared induction control device 20 comprises an infrared induction distance adjuster, and the infrared induction distance adjuster is connected with the pre-amplifier. The infrared induction distance adjuster is mainly used for adjusting the infrared ray receiving distance of the infrared pyroelectric probe; when the water sprinkler operates, the infrared induction distance is adjusted, a water pipe is connected to the water sprinkler, the water valve is opened, the infrared induction area, namely the infrared pyroelectric probe, is made to face protected flowers, grass and seedlings; when an animal is about to approach the protected area, the infrared pyroelectric probe detects an infrared ray signal emitted by the animal at the moment, and if it is judged through analysis by the central processing unit that the animal approaches, the electromagnetic water valve is opened to spray out a water column, and the water column swings left and right to repel the animal away. The intensities of infrared ray signals emitted by different animals are different, and the infrared induction distance adjuster can be adjusted to make the infrared pyroelectric probe receive infrared ray signals emitted by different types of animals, so that the selective adaptability to animals of different types is improved, and meanwhile, the repelling effect of the water sprinkler on animals which are different distances away is further improved.

[0025] Furthermore, the central processing unit is further connected with an irrigating/repelling selection controller and an operating time selection controller; through the irrigating/repelling selection controller, the water sprinkler of the invention not only can be used for repelling animals, but also can be used for irrigating flowers, grass and plants, and the application range of the water sprinkler is widened; through the operating time selection controller, the operating time of the water sprinkler can be selected and controlled, the central processing unit operates to judge whether an electromagnetic valve control signal needs to be output or not according to the state of the irrigating/repelling selection controller and the state of the operating time selection controller, and thus whether the water sprinkler needs to sprinkle water or not is intelligently controlled.

[0026] Furthermore, the operating time selection controller can be set in a daytime operating mode, a night operating mode or a 24-hour operating mode; the scene in the daytime and the scene at night are distinguished through a photosensitive detector 202 located on the upper cover 21, the photosensitive 202 transmits an outside light signal to the central processing unit, and after the outside light signal is processed by the central processing unit, whether the water sprinkler needs to operate or not is determined according to the state of the operating time selection controller. In this way, the water sprinkler can be kept in the operating state in the daytime or at night or in 24 hours selectively according to actual requirements of users; meanwhile, after the time limits are set, waste of water resources caused by continuous operating of the water sprinkler is avoided.

[0027] Furthermore, the infrared induction control device comprises a sprinkling duration regulator and a sprinkling interval regulator which are connected with the central processing unit. The sprinkling duration can be set according to requirements through the sprinkling duration regulator, the central processing unit determines the duration of an output electromagnetic valve control signal according to the set condition of the sprinkling duration regulator, and thus the electromagnetic water valve can be closed in real time; compared with the prior art that the sprinkling duration cannot be set, the purpose of saving water resources is achieved; through the sprinkling interval regulator, the sprinkling duration and the sprinkling interval can be set in absence of infrared induction, and thus plants, flowers and grass in parks and gardens can be irrigated automatically. When the irrigation function is selected, the sprinkling duration and the sprinkling interval are regulated, the operating time selection controller is set to operate in the daytime operating mode (or the night operating mode or the 24-hour operating mode), then the transverse sprinkling angle and the longitudinal sprinkling angle are adjusted, and then water can be automatically sprinkled to irrigate vegetable gardens, flower beds, lawns and the like according to the set sprinkling duration and the set sprinkling time interval without infrared induction.

[0028] Furthermore, as is shown in FIG. 1, the water inlet pipe 10 is further connected with a multifunctional blending box 11. As is shown in FIG. 4, a liquid adding port 110 is formed in the upper portion of the blending box 11, and a blended liquid outlet 111 is formed in the side, connected with the water inlet pipe 10, of the blending box 11; a water flow switch 112 is provided with a sealing rubber structure 113 used for sealing the blended liquid outlet 111, a pressure spring 114 is arranged on the upper portion of the water flow switch 112 and used for providing sealing force for the water flow switch 112 to seal the blended liquid outlet 111, an anti-backflow baffle 115 is further arranged below the blended liquid outlet 111, and a stop block 116 is arranged below the anti-backflow baffle 115 and used for supporting the anti-backflow baffle 115. After water enters the water inlet pipe 10, the anti-backflow baffle 115 and the water flow switch 112 are rushed open, liquid in the blending box 11 is then mixed into water to be sprayed out, and the water flow switch 112 and the anti-backflow baffle 115 can return to the original positions after water sprinkling is stopped, so that on the one hand, blended liquid in the blending box is prevented flowing back, and on the other hand, the blended liquid outlet of the blending box is closed; meanwhile, the anti-backflow baffle 115 prevents blended liquid left in the water inlet pipe 10 from flowing back into the portion, below the blending box 11, of the water inlet pipe 10, and thus pollution to a raw water source is avoided. The blending box is additionally arranged on the water sprinkler, and liquid such as a plant nutrient solution is added into the blending box, the liquid in the blending box flows into the water inlet pipe only when water is sprayed and is sprayed out after being mixed with water. For example, when plants in a garden are irrigated and a nutrient solution needs to be sprayed onto the plants, the user just needs to screw the blending box down from the water sprinkler, fill the blending box with the nutrient solution and then screw the blending box back onto the water sprinkle again, the nutrient solution in the blending box cannot flow into water at the moment, and the nutrient solution can be mixed with water and then sprayed to the plants only after the water flow switch is triggered by sprayed water flow; animal-sensitive powdery or aqueous agents can also be added into the blending box 11, and the liquid or powdery agents in the blending box cannot flow out to pollution the water source without water flow impact. In this way, compared with the prior art that only tap water can be sprayed, the application range of the water sprinkler of the invention is further widened through the multifunctional blending box.

[0029] Furthermore, the water sprinkler of the invention comprises a base 40, and as is shown in FIG. 5, the base 40 is provided with a load (located below the base and not shown in the FIGs). The base 40 is a fixed base; an existing water sprinkler is not provided with a base, can only be inserted into soft soil through a ground insert (a pointed object located at the lower end of the water sprinkler) so as to be fixed, and cannot be used on hard ground, and consequentially, the application range is limited. The big base and the load are adopted by the water sprinkler of the invention to replace the ground insert, so that the water sprinkler can be placed on hard ground and flat soft soil and in other environment; the load is added, so that the water sprinkler is prevented from inclining when spraying water, and thus the user can use the water sprinkler quite conveniently. As is shown in FIG. 5, the water sprinkler of the invention can be directly placed on flat hard road surfaces or soft road surfaces through the big chassis type base, and the load is additionally arranged on the base, so that the water sprinkle is prevented from falling when spraying water and can be used more conveniently.

[0030] Furthermore, the base 40 is provided with a water inlet 41 connected with the water inlet pipe 10; the water inlet 41 is formed in the base 40, so that the center of gravity is low when water is sprayed, the stability of the water sprinkler in use is improved, the situation that the center of gravity is instable when a water inlet is arranged at a high position, and consequentially the water sprinkle falls is avoided, and the water inlet 41 is provided with a standby water faucet 42. The standby water faucet is additionally arranged, so that when the user needs an extra water connector in use, the user just needs to turn on the standby water faucet 42 and then connect a water pipe to the standby water faucet 42; meanwhile, the standby water faucet 42 can also be connected to another one or more water sprinklers through water pipes, and thus the water sprinkling area is enlarged. The standby water faucet 42 is covered with a leakage-proof cover when not used. Through the standby water faucet, the user can use extra water connectors conveniently, and the using convenience of the water sprinkler is further improved.

[0031] From the above embodiment, the multifunctional infrared induction water sprinkler of the invention can prevent gardens, lawns, nursery gardens and the like from being infringed by animals and can also effectively repel animals; in addition, the multifunctional infrared induction water sprinkler can be used for automatically irrigating plants in flower gardens, vegetable gardens and the like and spraying nutrient solutions onto the plants. The multifunctional infrared induction water sprinkler of the invention is wide in application range and has good market application prospects.

[0032] Although the invention is disclosed through the above embodiment, the protection scope of the invention is not limited to the above embodiment, and transformations, substitutes and the like of the above components made without deviating from the concept of the invention are all within the claim range of the invention.
