DETAILED DESCRIPTION OF THE INVENTION
The purpose, construction, features, functions and advantages of the present invention can be appreciated and understood more thoroughly through the following detailed description with reference to the attached drawings.
With reference to FIGS. 1 and 6, a single pushbutton device for outputting water with multiple spray patterns in accordance with present invention includes a housing 1, a bubbler 2, a bushing 3, a water channel assembly 15, a rotary assembly 16, and a button 8.
The housing 1 is tubular and has a front end, a rear end and a hole 1-1. The hole 1-1 is formed through a peripheral wall of the housing 1. The button 8 is mounted through the hole 1-1 of the housing 1 and protrudes beyond the hole 1-1. The button 8 controls the rotary assembly 16 to rotate to adjust the water channel assembly 15.
The bushing 3 is mounted inside the front end of the housing 1, and the bubbler 2 is centrally mounted inside of the bushing 3. The bushing 3 has multiple waterways formed through the bushing 3 and outputting water with multiple spray forms.
The water channel assembly 15 includes multiple abutting inserts 4, multiple first spring 5 and a water tube 6. The water tube 6 has a front portion 6-1, a rear portion 6-2 and multiple recesses 6-3. The front portion 6-1 of the water tube 6 is connected with the bushing 3. The recesses are formed in the water tube 6, are located around the water tube 6, and communicate with corresponding waterways of the bushing 3. The water channel assembly 15 is collaborated with the bushing 3 to output water with multiple spray patterns through the corresponding waterways of the bushing 3. The abutting inserts 4 are mounted and are movable in the respective recesses of the water tube 6. Each first spring 5 is mounted between a corresponding abutting insert 4 and the water tube 6. Each abutting insert 4 has a nose 4-1 formed on a top of the abutting insert.
The rotary assembly 16 is mounted around the water tube 6 and includes a pressing frame 7, a rotary sleeve 9, a ratchet 10, a driving pawl 11 and a stop pawl 12. The rotary sleeve 9 has a front end and a rear end, and the ratchet 10 is mounted on the rear end of the rotary sleeve 9. The water channel assembly 15 is mounted inside of the rotary sleeve 9, and the rear portion 6-2 of the water tube 6 is connected with the ratchet 10. The rotary sleeve 9 has a bump 14 formed on an inner wall of the rotary sleeve 9 and selectively connected with the noses 4-1 of the abutting inserts 4. The pressing frame 7 is mounted around the ratchet 10, is mounted inside the housing 1, and has a projected portion 7-1 formed on a top portion of the pressing frame 7. The driving pawl 11 is mounted between the pressing frame 7 and the ratchet 10. Multiple second springs 13 are mounted between the pressing frame 7 and the housing 1. The stop pawl 12 is mounted between the ratchet 10 and the housing 1.
The button 8 is mounted through the hole 1-1 of the housing 1 and is mounted on the projected portion 7-1.
With reference to FIGS. 7 to 10, before the button 8 is pressed, the stop pawl 12 engages an initial tooth of the ratchet 10. When the button 8 is pushed down, the button 8 presses down the pressing frame 7, the pressing frame 7 further presses the second spring 13 and drives the driving pawl 11, the driving pawl 11 then drives the ratchet 10 to rotate, such that the stop pawl 12 engages a tooth of the ratchet 10 next to the initial tooth. When the button 8 is released, the restoring elastic force of the second spring 13 pushes the driving pawl 11 back to its original position.
As the pressing frame 7 is reciprocally moved inside of the housing 1 by the force exerted on the pressing frame 7 and the restoring elastic force of the second spring 13, when the ratchet 10 is moved and the stop pawl 12 engages a next tooth of the ratchet 10, the forces exerted on the pressing frame 7 can be balanced by the restoring elastic force in return, thereby causing no discomfort to user's hand upon pressing the button 8 because of unilateral force application.
After the button 8 is pushed down, the rotary sleeve 9 is rotated. Thus, the bump 14 is rotated with the rotary sleeve 9 and the bump 14 is rotated along the noses 4-1 of the abutting inserts 4. Only one of the abutting inserts 4 is pressed down by the bump 14 at a time for water to flow into a corresponding recess of the water tube 6 uncovered by the abutting insert 4 and flow out through different waterways of the bushing 3 to provide multiple water outputs and bubbling functions.
