Dry-tooth power box garden energy-saving water thrower

Abstract

A dry gear type power box garden energy-saving water sprayer comprises an energy-saving novel impeller shaft-free bracket electromagnetic flow meter and further comprises an electromagnetic flow meter, a water sprayer body, a flow-adjustable water dropper, a 360-degree sprayer head, an energy-saving spray irrigation timer and a water distributor. By means of the dry gear type power box garden energy-saving water sprayer, water saving is achieved. A spraying water sprayer water containing reverser can push a water rotating disk to slow down a gear set through water flow and then to drive a shifting swinging rod (5801) through a reverser disk (5821), the shifting swinging rod (5801) is deflected and bent in a deflection mode to enable head shifting plates to each press water flow holes (5801c) of two symmetrically water inlet / outlet pipes to achieve reversing, and inclined openings are formed in the water flow holes. However, the general mutability is unreliable. Tests show that the included angle between diagonal planes, where inclined openings are formed, of the water inlet / outlet pipes is not larger than 22.5 degrees, and namely the deflection angle of the shifting swinging rod (5801) is not larger than 22.5 degrees. The shifting swinging rod (5801) is optionally made of PBT honest materials, the shifting swinging rod is processed for many times, and then the shifting swinging rod is sleeved by an intensive-turn 304 stainless steel swinging rod deflection spring (5802) which is processed in a normalizing thermal mode. Thus, the problem of being difficult, changeable and unreliable in reversing is solved. Furthermore, gears of the dry gear type power box garden energy-saving water sprayer are not contacted with water, so that no incrustation is generated.

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 efficiency is affected by the cooperation of people; and the cost of metal materials is high, which makes the price of the finished flowmeter more expensive; therefore, it is necessary to improve the existing electromagnetic flowmeter
