Description

Technical Field

[0001] The utility model relates to the technical field of bathroom hardware, in particular to a lateral impact water flow generator. Background Art

[0002] Currently, a large number of shower bodies or faucets are equipped with water flow generators, which use the electricity generated by the water flow generator to drive the water temperature display device and atmosphere lights, etc., reducing the number of times users directly contact the water flow with their bodies to test the temperature, allowing users to minimize contact with over-cold or over-hot water, making use more comfortable.

[0003] However, the water flow drive mode of the common water flow generators on the market is generally bottom-in and side-out or bottom-in and top-out. In order to meet the requirements of the water flow direction, the water channel part of such a design occupies a relatively large volume, which is not conducive to installation in a small faucet. For example, the Chinese utility model patent with announcement number CN201858076U discloses a pipeline-type hydroelectric power generation device, which is connected to the shower handle pipe, including an impeller and a generator device that rotates as the water flows through. The generator device includes a magnetic rotor and a stator coil. The impeller and the generator device are assembled in a cylindrical shell. The generator device is sealed in a cavity in a way that completely isolates the water flow. The water flows in from the water inlet end of the cylindrical shell, and after impacting the impeller, it flows through the gap between the inner wall of the cylindrical shell and the encapsulation layer of the generator device and flows out from the water outlet end. The impeller is arranged with a magnet that matches the magnetic rotor. The rotation of the magnet drives the magnetic rotor of the motor to rotate in the same direction. The water flow generator of this utility model is a typical bottom-in and top-out mode, in which the water flow in and out direction is the same as the impeller shaft, the water energy impact efficiency is low, and matching water inlet and outlet joints need to be set at both ends of the power generation device during installation, resulting in this structure being less suitable for installation in a shower body through a mounting hole, especially for installation in increasingly lightweight flat shower bodies.

[0006] Furthermore, a streamlined groove is provided on the outer side wall of the water inlet guide ring along the water inlet direction of the water inlet, and the water inlet direction of the water inlet is nearly perpendicular to the blades in the impeller.

[0007] Furthermore, an annular filter screen is provided outside the water inlet of the water inlet guide ring, and a retaining edge for limiting the annular filter screen is provided in the water inlet guide ring.

[0008] Furthermore, a support foot is provided at the bottom of the inner cavity; and the upper end surface of the water inlet guide ring is in contact with the end surface of the support foot.

[0009] Furthermore, it also includes a temperature detection sensor, the temperature detector is arranged in the outer cavity, and the detection probe in the temperature detector extends from the probe hole in the partition into the inner cavity.

[0014] An isolation sealing ring is arranged between the water outlet and the water inlet in the installation body of the utility model, so that the water outlet can be isolated from the water supply waterway in a limited space, so that the waterway structure of the water flow generator can be made more compact.

[0015] The utility model provides a streamlined groove on the side wall of the water inlet of the water inlet guide ring, which makes the water inlet smoother and reduces the water flow power loss; the water flow entering from the water inlet is close to perpendicular to the blades of the impeller, which can convert the kinetic energy of the water into the kinetic energy of the impeller to the maximum extent, thereby increasing the power generation capacity of the power generation device.
