This application claims the priority of Chinese Application No. 201610603794.X, filed on Jul. 28, 2016 and the entirety thereof is herein incorporated with reference.
The preferred embodiment of the present invention is related to the field of a shower head and, more particularly, to a shower head with dual switches to allow the user to single-handed operate the water output pattern as well as water output.
Normally, a shower head provided inside the shower room allows the user to take a shower via a single switch to determine water output. If the user wants to change the water output pattern, the user will have to first remove the shower head from the shower seat and then manually rotate the diverter on the shower head to accomplish the objective. Even though, there are various diverters available on the market to allow the user to change the water output pattern, still, user's manual operation on the diverter is still necessary.
In order to obviate or mitigate the aforementioned problem, the preferred embodiment of the present invention is to provide a shower head with dual switches to allow the user to single-handed operate the water output as well as water output pattern.
It is an objective of the preferred embodiment of the present invention to provide a shower head having two switches to allow the user to operate the water output with one switch and water output pattern with the other switch.
In order to accomplish the abovementioned objective, the shower head constructed in accordance with the present invention includes a body having therein a waterway, a first switch installed on the body to control water output and a second switch to control water output pattern. With such a design, the operator (user) is able to operate the shower head with one hand to control the water output as well as water output pattern.
Still another objective of the preferred embodiment of the present invention is that the first switch is a mechanical, dual-position switch.
Still another objective of the preferred embodiment of the present invention is that the second switch is a mechanical switch with multiple positions.
Furthermore, the second switch of the shower head of the preferred embodiment of the present invention has a front pushbutton hinged to a surface of the body, a rocker operably connected to the front pushbutton, a sliding element one end of which is securely engaged with the rocker so that the sliding element is driven by the rocker to move linearly and the other end of which is provided with a rack formed on a face of the sliding element, a diverter rotatably mounted inside the body and having a shaft integrally extending out from a side face of the diverter, a gear rotatably mounted around the shaft and a rotor securely mounted on the shaft and having wolf teeth formed on a surface thereof to match with slanted teeth formed on a face of the gear such that when the rotor is rotated along with the shaft of the diverter in one direction, the gear is also rotated and when the rotor is rotated along with the shaft of the diverter is the other direction, only the rotor is rotated, but not the gear. A first recoil spring is provided between an inner face of the body and a side face of the rotor to securely abut the rotor against the gear to ensure that the wolf teeth is mated with the slanted teeth on the face of the gear.
Still another objective of the preferred embodiment of the present invention is that the first switch includes a rear pushbutton, a driving rod having a first ratchet teeth formed on a side face thereof, a diverting element having a rod extending into a central through hole defined in the driving rod and a second ratchet teeth formed on a side face thereof to mate with the first ratchet teeth of the driving rod and a second recoil spring provided between the inner surface of the body and a side face of the diverting element to secure that the first ratchet teeth engages with the second ratchet teeth of the driving rod.
Furthermore, a still objective of the preferred embodiment of the present invention is that the first switch and the second switch may be adjacent to one another.
A further objective of the preferred embodiment of the present invention is that a third recoil spring is provided between the side face of the body and the sliding element to return the sliding element to its original position after movement.
Preferred embodiment(s) of the present invention in combination with the attached drawings shall be provided in detail in the following description. However, the given description is for example purpose only and should not be deemed as a limiting to the scope of the present invention in any way.
In order to make it easy to carry out the preferred embodiment of the present invention, a detailed description of the parts of the invention, supported with figures is provided here. As each part of the preferred embodiment of the present invention has many features, it is made easy to read, by referring to each feature with a number included in the parts description text. The number of the parts feature(s) is indicated here by starting it sequentially from the number 1, wherever a part feature appears in a text, an associated serial number is directly assigned.
With reference to
With reference to
The second switch 4 is composed of a front pushbutton 401 hinged onto the body to allow the rear pushbutton 401 to pivot relative to the body 1, a rocker 402 an end of which is securely connected to a distal end of the rear pushbutton 401, a sliding element 403 linearly movable inside the body 1 and provided with a rack 4031 formed on a side face thereof, a diverter 5 rotatably received inside the body 1 for diverting water into different output holes defined in the diverter 5 to form various output patterns and having a shaft 501 integrally extending out from a side face of the diverter 5, a gear 6 rotatably mounted around the shaft 501 and a rotor 7 securely mounted on the shaft 501 and being immovable relative to the diverter 5 and having wolf teeth 8 formed on a surface thereof to match with slanted teeth 601 formed on a face of the gear 6 such that when the rotor 7 is rotated along with the shaft 501 of the diverter 5 in one direction, the gear 6 is also rotated and when the rotor 7 is rotated along with the shaft 501 of the diverter 5 is the other direction, only the rotor 7 is rotated, but the gear 6. A second recoil spring 9 is provided between an inner face of the body 1 and a side face of the rotor 7 to securely abut the rotor 7 against the gear 6 to ensure that the wolf teeth 8 is mated with the slanted teeth 601 on the face of the gear 6. Furthermore, a recoil spring 10 is provided between a distal end of the sliding element 403 and the inner side face of the body to provide a recoil force to the sliding element 403 to return to its original position after movement.
From the showing of
When the rear pushbutton 301 is pushed or pressed, the driving rod 302 is accordingly moved by the movement of the rear pushbutton 301. It is noted that due to the mutual relationship between the first ratchet teeth 304a and the second ratchet teeth 304b, the linear movement of the driving rod 302 drives the diverting element 303 to rotate, which results that the waterway 2 is accordingly and selectively on or off every time the diverting element 303 is rotated.
After a detailed description of the preferred embodiment(s) has been provided, any skilled person in the art would easily understand the description so provided is for example purpose only. The scope for protection of the present invention is defined by the attached claims. Any skilled person in the art would easily amend, modify or alter the elements/devices of the present invention without departing from the principle essence and spirit of the present invention. However, the amendment, modification or alteration shall fall within the protection scope sought of the present invention.
