The present invention relates to a bathroom accessory, and more particularly to a shower head structure able to provide a water discharge flow that is grouped or bunched to improve the feel of the discharged water.
With the improvement of people's living standards, people pay more attention to the quality of life and also whether a product is environmentally-friendly and efficient so as to not be wasteful of resources. For taking a shower, people now pay attention to the feeling of the water flow that falls on them during the shower and the water-saving effect. Numerous existing shower heads provide discharged water flow that does not provide physical ease and relaxation, instead, the water flow sprays in an uneven pattern that wastes some water, and is not environmentally friendly.
Accordingly, the present invention is intended to solve this problem and other shortcomings that are common to conventional shower heads. A full discussion of the features and advantages of the present disclosure is deferred to the following detailed description, which proceeds with reference to the accompanying drawings.
The present invention provides a shower head assembly which can increase the force of the outflow of water or discharge water effectively. The discharged water flow is grouped or arranged to provide “bubble water flow” that feels soft and comfortable to the user or person taking a shower under the inventive shower head. The discharged water flow avoids random spray that conserves water and improves the water-saving effect of the shower head. The shower head of the present invention is also suitable for low water pressure environment.
The shower head assembly includes a main body, a face plate or panel that is provided with at least one water outlet unit where the water outlet unit includes at least two jet orifices. The water outlet unit include a plurality of water outlet units that are spaced from each other. The water outlet units comprises a cluster of jet orifices that include the at least two jet orifices of the water outlet unit, such that the clusters of jet orifices are spaced from each other. The at least two jet orifices of each of the clusters are spaced from each other by a predetermined distance between the jet orifices. The jet orifices of the clusters of the plural water outlet units being structured to jet water therefrom at the same time.
In one example, the jet orifices each have a diameter of 0.2 mm-0.7 mm. In one example, the jet orifices each have a diameter of 0.2 mm-0.5 mm. In one example, the jet orifices each have a diameter of 0.5 mm-0.7 mm. In one example, the jet orifices each have a diameter of 0.2 mm-0.3 mm. In one example, the jet orifices each have a diameter of 0.3 mm-0.5 mm.
In one example, the predetermined distance between the jet orifices is more than 1 mm.
According to another aspect of the invention, the shower head assembly further comprises a bubbler installed in an intermediate or middle portion of the face plate. The at least one water outlet unit is disposed on a circumferential portion of the face plate around the bubbler such that the clusters of jet orifices are arranged circumferentially around the bubbler.
According to another aspect of the invention, the main body comprises a housing and a water diversion body. The housing and the water diversion body are separate structures to be assembled together to form a combined component of the shower head assembly. Alternatively, the housing is integrally formed with the water diversion body.
According to another aspect of the invention, the face panel or plate is directly formed to the main body. The face panel is made of a plastic material by injection molding.
In one example, the at least one water outlet unit is formed of rubber materials by molding and then the face panel is formed by over-molding the plastic materials onto the at least one water outlet unit.
In one example, the face panel and the at least one water outlet unit are assembled together, wherein the at least one water outlet unit is formed as one or more pieces with rubber materials by molding. Also, the face plate is formed from plastic materials by molding.
According to another aspect of the invention, a switching device is installed inside the main body for controlling an outflow of water from the face plate. The face panel of the present invention has a plurality of water outlet units, wherein each water outlet unit includes a plurality of jet orifices. The water discharged or flowing from the plurality of jet orifices forms a bunched or arranged spout of discharged water flow that includes a plurality of fine spouts that avoids random, inefficient spray. Since the diameter of the jet orifice is small, the force of the fine spouts is strong and the water-saving effect is good. The shower head of the present invention can be used for low pressure water environments.
Other features and advantages of the shower head assembly will be apparent from the following specification taken in conjunction with the following drawings. Additional advantages and novel features will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following and the accompanying drawings or may be learned by production or operation of the examples.
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.
As shown in
The center of the front of the face plate 2 has an installation trough 21 for installation of the bubbler 3. The bubbler 3 is removably connected to the installation trough 21 by a fastener, such as a threaded fastener. A searing ring is provided between the bubbler 3 and the installation trough 21. The center of the rear of the face plate 2 has a cylindrical first outlet chamber 22 communicating with the installation trough 21. The rear of the face plate 2 further has an annular second outlet chamber 23.
The circumferential portion of the front of the face plate 2 is provided with at least one water outlet unit 24. The water outlet unit 24 communicates with the second outlet chamber 23. The number of the water outlet units 24 is dependent on the required water discharge amount. The water outlet unit 24 includes at least two jet orifices 241. The water outlet unit 24 is shaped by the arrangement of the jet orifices 241. As shown in
The diameter of each of the jet orifices 241 is in a range of 0.2 mm-0.7 mm. In this way, it can ensure that water outlet unit 24 provides the desired water discharge flow and pattern while still being suitable for use in different water pressure environments. That is, even if the water pressure environment is relatively low, the water outlet unit 24 still can provide “clusters” of thin water jets with a mist shape and a relatively strong force, without any unsuitable feeling of the water flow for the person taking a shower.
This enables the shower head assembly to generate and discharge “clusters” of thin water jets for purposes of modulating a force of an outflow of water such that the water flow provides a relatively “soft” feeling for uses and undesired splashing of water can be reduced. This helps to save water and allows the shower head assembly to function normally even in a low pressure environment.
Preferably, in one example, the diameter of the jet orifices 241 each is between 0.5 mm and 0.7 mm. In another example, the diameter of the jet orifices 241 each is between 0.2-0.5 mm. The diameter of the jet orifices 241 can also have any other suitable ranges, for example in a range of 0.2 mm-0.3 mm or 0.3 mm-0.5 mm. The distance between the two jet orifices 241 is more than 1 mm.
The face panel 2 is directly formed, or it may be made of a plastic material by injection molding or a rubber material by molding, or assembled by molding. In one example, the at least one water outlet unit 24 is formed of rubber materials by molding and then the face panel 2 is formed by over-molding the plastic materials onto the formed at least one water outlet unit 24. In another example, the face panel 2 and the at least one water outlet unit 24 are assembled together, wherein the at least one water outlet unit 24 is formed as one piece or more pieces with rubber materials by molding and the face plate 2 is formed by plastic materials or metal materials by molding.
