Background technique

my country is a country with a large population and a large water consumption country. At the same time, it is also a country with poor water resources and low per capita water resources. Therefore, the country vigorously advocates saving water resources and avoiding waste. Otherwise, the last drop of water for human beings will be human tears. Although it is a bit exaggerated, it also fully shows Conservation of water is imminent, and the necessity of building an energy-saving and environment-friendly society. In daily family life, people use water in their daily life, such as eating, washing, and bathing. Among them, the water consumption of bathing accounts for a high proportion of the entire domestic water consumption. , the per capita bathing frequency increases, and the bathing is mainly in the form of showers. The long flushing time in the shower will also cause high water consumption, and the reduction of flushing time and shower frequency in the shower will cause insufficient bathing and affect the quality of life. How to reduce the consumption of water from the shower still remains to be solved technically.

detailed description

Embodiment 1 of the present invention, as shown in Figures 1, 2, and 3, the pulsating water-saving shower device with side holes includes a valve body 1 and a valve core 2, and the valve body is a rotary body with inlet connecting threads 3 respectively. And the outlet connection thread 4, the inlet connection thread is connected with the water inlet pipe 5, the outlet connection thread is connected with the nozzle 6, the outlet end of the valve body is provided with a partition 7 for blocking the outlet of the valve body, and the center of the partition is provided with the outer side of the partition. The shaft 8 extending toward the valve body along the axis of the valve body is provided with at least two bottom holes 9 evenly distributed in the circumferential direction of the partition near the periphery of the shaft near the edge of the partition. The number of inner holes in this embodiment is eight. , there must be at least two during implementation. The lower part of the valve core body 20 is provided with a shaft hole set on the shaft, which can rotate around the shaft. The upper part of the valve core body is connected with a synchronously rotating impeller 10, and the blades 11 are evenly distributed in The valve body flows into the inside, a pit 12 is provided at the axial center of the upper end of the main body of the valve core, a support bowl 13 is provided at the outlet, and a protrusion 14 pressed in the pit is provided at the bottom of the support bowl, and a through hole 15 is provided around the protrusion , the support bowl is provided with a filter body 16; the bottom hole is pressed with a conversion ring 17, and the contact surface between the conversion ring and the partition is provided with eight conversion holes 21 corresponding to the bottom holes one by one. There are eight side holes 22 open on the side, matching positioning protrusions and positioning holes are respectively provided on the contact surface of the conversion ring and the partition plate, and the positioning is connected. Half of the valve plate 19, the side of the valve plate can simultaneously block the side holes corresponding to the number of valve plates and release the side holes at the same time. In this embodiment, the inner end of the shaft rod is smooth, of course, it can also be sharp, and it is placed on the top of the shaft hole At the bottom, there is a gap between the valve plate and the partition after it is placed on the top, which can reduce the frictional resistance with the partition when rotating, that is, ensure that there is fluid flowing through the inner hole at all times. There are six valve plates in this embodiment, and the valve plate A group of three can close three adjacent inner holes at the same time, and the two sets of valve plates are evenly arranged in the circumferential direction. When the valve plates close six inner holes, two inner holes with symmetrical positions are opened to provide a balanced blade. Power, when the pulsating water-saving shower device with side holes of the present invention is used, the inlet is connected with a water inlet pipe, and the outlet is connected with a nozzle. The high-pressure water flows through the valve body, and the water impacts the blades to drive the impeller to rotate, and the impeller drives the valve core. The main body and the valve plate rotate, the valve plate closes and releases part of the inner hole at the same time, and the bottom hole is intermittently connected, so that the shower head sprays pulsating water flow, and the pulsating water flow provides comfortable pulse impact massage for the human body, improving comfort. , the amount of water per unit time is reduced, saving water, and the present invention always has part of the inner hole open during the shower process, and the retained flow provides power for the impeller. The pulsating water flow also provides fast recovery power for the impeller, and the rotation resistance of the impeller is small. , The structure is simple and small, which is convenient for installation.

During implementation, the number of inner holes is the same as that of the bottom hole, and the number of inner holes is larger than that of the valve plate, which not only ensures that the inner holes are open at all times, but also has a part of inner holes that switch between open and closed, in order to better adjust the flow rate and facilitate manufacturing. , the number of inner holes is 4 to 16. The number of inner holes is an integral multiple of the number of valve plates. The valve plates that can simultaneously block adjacent inner holes form a group. The number of valve plates in each group is the same and each group is evenly arranged in the circumferential direction. Cloth can provide balanced power for the blades. Of course, asymmetrical power can also drive the blades, and the purpose of the present invention can also be achieved, but the balanced power has a longer service life and smoother operation; during implementation, it can be hard-filled in the inner space of the nozzle Particles, the volume of particles is fixed, there is no change in compression, and the filling rate of particles is greater than 70%, so that the water flow can flow out smoothly, and at the same time, there is a small space for water retention, thereby reducing the volume of water compression deformation and reducing pulse absorption amount, so that the pulsed water flow is more directly transmitted to the sprayed water column.

In summary, the above is only a preferred embodiment of the present invention, and all equivalent modifications and additions made in accordance with the present application are regarded as the technical scope of the present invention.
