The present invention relates to a shower, and more specifically to a rotary switched shower which has multiple functions of water outlet and its method of switching.
The shower in existing technology has already not only had the function of sprinkling water, but also had multiple functions of water outlet to satisfy the demands of different people and different time, which has been used extensively. In order to exchange functions of water outlet, people often use the switch set up in the existing multifunction shower. In order to make it more convenient to switch water channels, sometimes a plectrum, which is used to turn the front cover to rotate, is set up on the front cover. But because of the smaller volume of the front cover, when user is holding it, the contact area is too small to hold it easily, which makes it difficult to turn the front cover to rotate. For example, the inventions published in the Chinese patent applications No. CN101041146A and No. CN201042681Y both have the above shortage.
The main purpose of the present invention is to overcome the shortage of the inconvenience of switching different function water channels and the present invention supplies a rotary switched shower and its method of switching.
The present invention adopts the following technology programme:
A rotary switched shower includes a shell, a front cover, a handle, and a device of water outlet. The handle is connected with the shell and could rotate around it. The shell and the front cover are fixed to each other, and they form a chamber in which the device of water outlet is laid out. The device of water outlet and the front cover form at least two function water channels. In the chamber, a turntable fixed to the handle and an upper water segregator fixed to the shell are in contact with each other, and a water inlet hole is set up in the turntable. At least two function water holes set up in the upper water segregator, each of which is constantly connecting with a function water channel. When turn the shell a certain angle relative to the upper water segregator, the water inlet hole in the turntable is connected with a function water hole in order to make the relevant function water channel connected with the water inlet hole.
In one preferable embodiment of the present invention, the said device of water outlet includes a lower water segregator, an impeller, a commutator and a TPR cover, which together with the said front cover form a massage water channel, a spray water channel and a shower water channel. Correspondingly, the said water upper segregator has a massage water hole, a spray water hole and a shower water hole.
In one preferable embodiment of the present invention, additionally a blind hole for assembly is set up in the upper water segregator.
In one preferable embodiment of the present invention, the said lower water segregator and the said front cover fit together and form a shower water chamber, a massage water chamber and a spray water chamber which are arranged from outside to inside.
In one preferable embodiment of the present invention, the said impeller laid out in the massage water chamber rotates with water flow in the massage chamber, which consists of a horizontal arc plate and several vertical blades on the arc plate.
In one preferable embodiment of the present invention, the said shell covers and encloses the front cover.
In one preferable embodiment of the present invention, an assembly hole is set up at the top of the shell, and at the end of the said handle a head is added down-facing, which is inserted into the assembly hole and is fixed to the turntable with a screw.
A switching method of the rotary switched shower, comprises the following steps: (1) turn the shell to rotate relative to the handle, when the water inlet hole in the turntable fixed to the handle connects with the one of the function water holes, the relevant function water channel is connected. (2) continue to turn the shell to rotate relative to the handle, when the water inlet hole in the turntable fixed to the handle connects with another one of the function water holes, the relevant function water channel is connected.
From the above description of the present invention, we can see, compared with the existing technology, the rotary switched shower has the following advantage: the present invention makes the turntable fixed to the handle, the upper water segregator fixed to the shell, and user could turn the shell to rotate relative to the handle so as to switch the relevant function water channel. And because of the larger volume of shell, when user is holding it, the contact area is lager and the hand feel is nicer, which make it more convenient to switch.
Referring to
The turntable 40 is in contact with the upper water segregator 50 which connects with the device of water outlet; a water inlet hole 41 is set up in the turntable, and because of the turntable fixed to the head 21 of the handle 20, after flowing out of the head 21 of the handle 20 water only flows from the water inlet hole 41 of the turntable 40 to the upper water segregator 50. In the upper water segregator 50, a shower water hole 51, a massage water hole 52, a spray water hole 53 and a blind hole 54 are set up, and the blind hole 54 is used for alignment assembly of the present invention in production.
The device of water outlet includes a lower water segregator 61 under the upper water segregator 50, an impeller 62, a commutator 63 and a TPR cover 64. The lower water segregator 61 and the front cover 30 fit together and form a shower water chamber 65, a massage water chamber 66 and a spray water chamber 67 which are arranged from outside to inside. The TPR cover 64 is embedded in the front cover 30 in the shower water chamber 65, so shower water flows out of the shower water chamber 65. The impeller 62 set up in the massage water chamber 66 rotates with water flow, which consists of a horizontal arc plate 621 and several vertical blades 622 on the arc plate 621. In the massage water chamber 66, water flow impacts the impeller 62 to rotate so as to generate massage water. In the spray water chamber the commutator 63 is set up to generate spray water.
The upper water segregator 50, the lower water segregator 61, the impeller 62, the commutator 63, the TPR cover 64 and the front cover 30 together form a shower water channel S1, a massage water channel S2, a spray water channel S3.
In the present invention, the seal rings 71, 72, 73 are set up at junctions of all the parts to form a sealed internal environment where water flows.
In the present invention, because the turntable 40 is fixed to the handle 20 with a screw 74, the upper water segregator 50, the front cover 30, and the shell 10 are fixed together, and the turntable 40 and the upper water segregator 50 are contact with each other, when turn the shell 10 to rotate relative to the handle 20, the water inlet hole 41 in the turntable 40 is in turn connected with the shower water hole 51, the massage water hole 52 and the spray water hole 53 in the upper water segregator. As a result, the rotary switched shower of the present invention could generate shower water, massage water and spray water in turn.
In the present invention, because of the larger volume of the shell, when user is holding it, the contact area is larger and the hand feel is nicer, which makes it more convenient to switch.

In addition, although in the embodiment, the upper water segregator, the device of water outlet and the front cover form together the shower water channel, the massage water channel and the spray water channel in order to make the rotary switched shower of the present invention could generate shower water, massage water and spray water. But actually, the importance of the claims in the present invention is not how many water channels are and what types of water channels are, but the rotation of the shell and the handle, and in this invention the way of switching water channels is to turn the shell to rotate relative to the handle by hand. Because of the larger volume of shell, when user is holding it, the contact area is lager and the hand feel is nicer, which make it more convenient to switch. Therefore all the showers having two types of water outlet are in the scope and spirit of this invention, no matter how many types of water channels are and no matter what types of water channels are.
In a word, all above is just one of the embodiments in the present invention, but the present invention is not limited in the embodiment. It should be understood that according to the design concept of the present invention, all the unessential modifications and alterations of the present invention will be apparent in the scope of claims of this invention.
