Technical Field

The invention relates to the technical field of machinery, in particular to a spring-triggered periodic water-saving faucet and a water saving method thereof.

background

According to the investigation result of the daily water condition investigation and water-saving consciousness analysis of people, the people who adopt the flowing clear water washing mode account for 66.67 percent, which shows that the phenomenon that the flowing clear water washing dominates, thereby causing unnecessary waste of water generated by continuous water flow between hand holding water receiving and washing, and having great water-saving potential.

at present, common water-saving taps on the market comprise time-delay self-closing taps, induction taps, mechanical water-saving taps and the like. For the water waste caused by washing with flowing clear water, a water-saving product is not targeted for the time. For popularization of the water-saving faucet, survey data shows that 94.3% of residents commonly use common mechanical faucets in families, only 5.7% of users purchase delay self-closing faucets and induction faucets at home, and the popularization effect of the delay self-closing faucets and the induction faucets in the residents is poor.

Disclosure of Invention

in order to effectively avoid the water waste phenomenon caused by continuous water flow between hand holding water receiving and washing room, the invention provides a clockwork spring triggered water-saving faucet which can control the periodic water outlet of a common mechanical faucet and does not influence the normal continuous water outlet of the common mechanical faucet.

the invention provides a spring-triggered periodic water-saving tap, which comprises: the spring is arranged on the rotary knob, and the spring is connected with the first gear, the second gear, the third gear, the fourth gear, the water pipe and the wafer; wherein the first gear is fixed on the knob; the spring is connected with the knob; the second gear is meshed with the first gear; the bottom of the second gear is provided with a sliding space, the sliding space is formed by connecting a third gear and the second gear through a threaded bar, the second gear and the threaded bar are integrated, the third gear can drive the threaded bar to rotate along with the rotation of the second gear, and the third gear rotates along with the rotation of the threaded bar and is in contact with or separated from the third gear through rotation; the fourth gear is meshed with the third gear; the wafer is arranged in the water pipe and is connected with the fourth gear to rotate.

In the present invention, the third gear may slide on the screw by rotating, and may contact or separate from the second gear by rotating and sliding.

In the invention, all materials of the water faucet are stainless steel, PVC or UPVC materials.

In the invention, the diameter of the water pipe is 15-30 mm and 0.12-0.16 MPa.

In the invention, the size of the water tap is 0.1 × 0.1 m-0.8 × 0.8 m.

Based on the faucet provided above, the invention also provides a water saving method of the spring-triggered periodic water-saving faucet, which comprises the following steps:

a force accumulation step: the first gear is rotated by rotating the knob, so that the second gear is driven, and meanwhile, the torque of the spring is gradually increased; in the process that the second gear rotates clockwise/anticlockwise under stress, the second gear is separated from the third gear due to the fact that the bottom of the second gear is provided with a sliding space; at the moment, the wafer loses external force and keeps parallel to water flow under the water pressure, so that the water flow is maximized;

force releasing step: when the moment of the spring reaches a large enough value, the knob stops rotating and is released; the spring drives the first gear to rotate reversely; the second gear meshed with the first gear rotates along the anticlockwise/clockwise direction, so that the second gear is contacted with the third gear, and the fourth gear is driven to rotate; the fourth gear drives the wafer to rotate, so that the water flow is periodically changed.

The technical scheme adopted by the invention for solving the technical problems is as follows: according to the lever moment principle, when the clockwork spring is full and the moment is maximum, after the clockwork spring runs for a period of time, the clockwork spring tightly wound on the clockwork spring shaft can be slowly loosened, the wafer is driven to rotate by the gear to control water outlet, and therefore the purpose that the water quantity is periodically changed is achieved. When the spring is completely restored, the wafer is kept parallel to the water flow under the pressure generated by flowing water, and the faucet can normally and continuously discharge water.

the innovation of the invention is as follows: when the flowing clear water is used for washing, a newly-added periodic water outlet function can be selected independently, and the aim of saving water is fulfilled under the condition of meeting the water use requirement; the water faucet does not use electric energy, has low energy consumption, and is favorable for popularization by combining with a common mechanical water faucet.

The invention has the advantages that when the flowing clear water is used for washing, a newly increased periodic water outlet function can be selected independently, and the purpose of saving water is achieved under the condition of meeting the water use requirement. The water faucet does not use electric energy, has low energy consumption, and is favorable for popularization by combining with a common mechanical water faucet. The faucet device is simple in structure, low in material price and beneficial to large-scale popularization. Compared with the traditional mechanical faucet, the mechanical faucet is simpler to operate, and the aim of saving water can be fulfilled by utilizing the periodic water outlet function. And the energy consumption is low, which is more beneficial to environmental protection. At present, most of users are provided with traditional mechanical faucets at home, and the purpose of environmental protection and water saving is difficult to achieve.
