A dual turbine showerhead provides multiple spray modes emanating from the head. The showerhead includes an inlet orifice, a backplate, a first turbine located side-by-side with a second turbine, a faceplate forming a first orifice group and a second orifice group, a first fluid channel in fluid communication with the first and second turbines and the first orifice group, and a second fluid channel in fluid communication with the second orifice group. In another embodiment, the showerhead includes first and a second turbines located side-by-side and a valve body that channels a fluid to the first turbine and the second turbine. In another embodiment, the showerhead includes a first and a second turbine located side-by-side along a centerline of the showerhead, a corresponding outlet region is arranged along the centerline and additional outlet regions are laterally spaced therefrom.

A switching method of a button switching shower includes: step 1, pressing a button slidingly connected to the shower, and then the button slides; step 2, the button acts on the linking seat of the pawl for rotating the pawl; step 3, the pawl rotates the ratchet wheel through the control end of the pawl, and the shape of the elastic claw of the pawl is changed for restoring energy; step 4, the rotation of the ratchet wheel rotates the water diversion disc, and then the water diversion disc is in place, and then the water diversion disc switches the outlet functions, the stopping claw of the pawl is against the ratch of the ratchet wheel for stopping the ratchet wheel inversion; step 5, the pressing is loosened for resetting the button, and the elastic energy of the elastic claw is released for resetting the pawl.

The present disclosure is related to a showerhead including a housing, a turbine, and a shutter. The housing defines a fluid inlet and a chamber in fluid communication with the fluid inlet. The chamber includes a plurality of engagement teeth and defines outlets for a first nozzle bank and a second nozzle bank. The turbine is received in the chamber. The shutter is received in the chamber and rotatably coupled to the turbine such that rotation of the turbine causes movement of the shutter. The shutter includes a plurality of shutter teeth positioned around a perimeter of the shutter. Engagement of the shutter teeth and the engagement teeth act to restrict the shutter from rotating while allowing the shutter to move across the chamber in a sliding motion.

A garden watering device is configured for use in handheld and ground-based operation. The garden watering device includes a device body having a water inlet and a handle. The garden watering device also includes at least one water distribution member adapted to spray in multiple patterns. In one example, the at least one water distribution member includes an elongate tube with a series of discharge outlets and a multi-pattern head with at least one flow outlet. The garden watering device also includes a flow route selector that routes water to either the elongate tube or the multi-pattern head.

A coupling structure of a spray head and a connector of a water spray gun is provided. An outer wall of the connector is provided with a positioning flange. The rear end of the spray head is provided with a stop plate. The rear end of the spray head is provided with a positioning rim. When the connector is inserted into the accommodation space of the spray head, the stop plate is secured in the positioning rim and connected with the rear end of the spray head. The stop plate has an annular area to get contact with the positioning flange provided on the outer wall of the connector, such that the spray head and the connector are assembled to become one-piece. The size of the spray head is reduced, so it is light and cost-effective. The water spray gun is able to provide different spray modes.

A method of generating a building assembly that includes spraying a coating material onto a plurality of pieces of substrate disposed on a first assembly face. The spraying includes spraying the coating material onto the plurality of pieces of substrate via a sprayer configured to apply the coating material to a target surface via a nozzle coupled with a mobile storage container storing the coating material, the coating material impregnating voids of the substrate. The method also includes allowing the coating material impregnating the voids to dry and harden and become rigid to generate the building assembly.

A water sprayer head has a guiding base and a positioning cover. The guiding base has a main body with a plurality of guiding columns, each guiding column having a respective central guiding hole and at least one distributing aperture at a front end connected to the guiding hole, a diameter of the distributing aperture being smaller than a diameter of the guiding hole. The positioning cover has a front end portion and a rear end portion, the rear end portion has a plurality of sleeve holes corresponding to the number and positions of the guiding columns, each sleeve hole has at least one aperture passing through the front end portion and having a diameter smaller than the diameter of the respective distributing aperture.

A water spray gun includes a main body, an operating member and a switch part. The main body includes a handle portion and a tube portion extended from the handle portion and provided with a spray head. A control assembly is enclosed in the main body for control of water outflow and adjustment of the amount of the water outflow. The operating member is pivotally connected to the position where the handle portion meets the tube portion. The switch part is arranged at the operating member and is engaged with the control assembly. The amount of water outflow is controlled by relative movement between the switch part and the operating member.

Provided is a gas showerhead with controllable airflow distribution, disposed in a cavity of a thin film deposition device and including: a first-layer panel, having a plurality of first gas supply holes distributed according to a first rule; and a second-layer panel, seated on the first-layer panel and having a plurality of second gas supply holes distributed according to a second rule. The first rule is different from the second rule, and one of the first-layer panel and the second-layer panel is capable of rotating at least by a specific angle relative to the other, so that the two panels have a first position and a second position that are different relative to each other. At the first position, none of the first gas supply holes is covered by the second-layer panel; and at the second position, a portion of the first gas supply holes are aligned with the corresponding second gas supply holes, and the other portion of the first gas supply holes are covered by the second-layer panel. The gas showerhead can adjust the airflow distribution and the airflow rate, which helps to meet the spraying requirements of different thin film deposition processes, and improves the uniformity of a deposited thin film.
