Humidity sensing intelligent watering timer

Abstract

A humidity sensing intelligent watering timer contains a water-through wet reverser. A gear set of the reverser is wet, and the gears in the gear set are cycloidal and thus durable. Each rocking nozzle (59) is sequentially sleeved with a right slot 1 (5951), a right slot 2 (5952), a right slot 3 (5953), a right slot 4 (5954), a right slot 5 (5955), a right slot 6 (5956), a right slot 7 (5957), a left slot 1 (5951a), a left slot 2 (5952a), a left slot 3 (5953a), a left slot 4 (5954a), a left slot 5 (5955a), a left slot 6 (5956a) and a left slot 7 (5957a), of which the inclination angles gradually increase, of a drive plate (598). A rack-shaped worm (596) is arranged on the drive plate (598) and is meshed with a worm gear (597) arranged on a rocking sprinkler, and the reliability is ensured by making use of the self-locking feature of the worm gear and the worm.

Problems solved by technology

Existing products vary, and none of them are perfect; there is a certain nozzle (55ac), such as Figure 31 As shown, the water is connected to the nozzle seat (55c) of the certain nozzle (55ac) through the matching components and then sprayed out through the only small square hole provided on the nozzle cap as the water nozzle (55a3c). Its disadvantage is that the range of sprayed water is narrow, and it cannot have a 360-degree all-round irrigation effect.

Another nozzle (55ad) for existing products, such as Figure 32 As shown, the water is connected to the nozzle seat (55c) of the certain nozzle (55ad) through the matching components, and is sprayed out through the large through hole opened on the half side of the nozzle cap as the water nozzle (55a3d) , its shortcoming is that the range of sprayed water is only half, and cannot have a 360-degree all-round irrigation effect

The existing electromagnetic flowmeter is made based on Faraday's principle of electromagnetic induction. When the conductor cuts the magnetic force line in the magnetic field, an induced potential proportional to the liquid flow rate is generated, and is detected by the electrode in contact with the liquid, so that it is converted by the cable. After intelligent processing, the communication and control between the flow data and the computer are realized. The existing electromagnetic flowmeter includes a measuring tube, an inlet flange, an outlet flange, electrodes, an excitation wire, a measuring tube housing, a circuit board and The display device, in which the measuring tube, the inlet flange, the outlet flange and the measuring tube housing are all made of metal materials, the disadvantages of using metal materials are: the weight of the entire flowmeter is relatively large, and it is inconvenient to install and maintain. The work is completed with the cooperation of people, which affects work efficiency; and the cost of metal materials is high, making the price of the finished flowmeter more expensive
