1. Field of the Invention
The present invention relates generally to a liquid container and more particularly, to a liquid container that can extend the lifespan of a filter core contained therein.
2. Description of the Related Art
A conventional liquid container, such as water filter, mainly comprises a container barrel and a filter core installed inside the container barrel. Usually, the container barrel is provided with a liquid inlet aiming the filter core for introducing non-filtered water into the container barrel, and a wastewater discharging hole located at a lateral side of the container barrel for discharging wastewater generated by washing the container barrel. Because the liquid inlet of the conventional liquid container is designed to be aimed at the filter core, the non-filtered liquid introducing into the container barrel will have a high pressure directly exerting on the filter core to cause a damage of the filter core or to wash the impurities attached on the filter core away from the filter core to lower the quality of the filtered liquid. In addition, the conventional liquid container has a drawback that the wastewater accumulated at the bottom portion of the container barrel can not be totally discharged out of the container barrel through the wastewater discharging hole that is located at the lateral side of the container barrel.
The present invention has been accomplished in view of the above-noted circumstances. It is therefore one objective of the present invention to provide a liquid container that can extend the lifespan of the filter core contained therein and enhance the quality of the filtered water.
Another objective of the present invention is to provide a liquid container that can completely discharge out the wastewater contained therein.
To achieve the above-mentioned objectives, a liquid container provided by the present invention comprises a container barrel and a pressure reducing device. The container barrel includes a liquid inlet and the pressure reducing device is mounted to the container barrel and corresponds to the liquid inlet. Since the pressure reducing device can depressurize the pressure of the liquid entering the container barrel from the liquid inlet, the noise generated by the impact of the liquid on the container barrel can be reduced.
In the liquid container of the present invention, the pressure reducing device may be a vortex generator to reduce the pressure of the liquid entering the container barrel.
In a preferred embodiment of the present invention, the liquid container further comprises a filter core, which is disposed inside the container barrel and corresponds to the liquid inlet, such that the liquid container of the present invention can have a filtering function.
In addition, since the pressure of the liquid entering the container barrel can be effectively reduced, a damage of the filter core can be prevented and the impurities attached on the filter core can hardly be washed out from the filter core, such that the lifespan of the filter core can be extended and the quality of the filtered liquid can be enhanced.
In a preferred embodiment of the present invention, the liquid container further comprises a wastewater discharging member disposed at a bottom portion of the container barrel for facilitating discharge of the wastewater generated by water washing over the container barrel.
Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
The present invention will become more fully understood from the detailed description given herein below and the accompanying drawings which are given by way of illustration only, and thus are not limitative of the present invention, and wherein:
As shown in
The container barrel 20 is made from stainless steel and shaped like a cylinder. As shown in
The cap 30 is made from a stainless steel material and provided with a horizontally extending end edge 31. The cap 30 is capped on the top side of the container barrel 20 to prevent dust from entering into the container barrel 20. As shown in
The pressure reducing device 40, which is realized as a vortex generator 40 in this preferred embodiment, has an outer frame 41 and a plurality of blade 43 inclinedly extending from a center of the pressure reducing device to the outer frame 41. The frame 41 of the vortex generator 40 is mounted to the container barrel 20 in such a way that the blades 43 partially block the liquid inlet 25 to guide the stream of the non-filtered liquid entering the container barrel 20 from the liquid inlet 25 so as to depressurize the pressure of the aforesaid liquid. It will be appreciated that the pressure reducing device 40 is not limited to the aforesaid vortex generator. Any device that can achieve the purpose of reducing the pressure of the entering liquid may be used as the pressure reducing device 40.
The filtering unit 50 is embodied in this preferred embodiment as, but not limited to, a detachable filtering unit. In other words, the filtering unit 50 can be a fixed unit. As shown in
The mounting rod 60 has a driven tab 61 and a rod-like shank 63 connected with the driven tab 61 and provided at a bottom portion thereof with a thread.
The support member 70 is formed of a hollow tube having a shank 71 and a flared head 73 that flares from the top of the shank 71. The flared head 73 has a plurality of through holes 731 for the passing of filtered liquid.
The wastewater discharging member 80 includes a head 81, a body 83, a tail 85, a liquid discharging valve 87, and a through hole 801 penetrating through the head 81, the body 83 and the tail 85, and having a threaded section corresponding in location to the head 81 and an upper portion of the body 83. The lower portion of the body 83 has three liquid discharging holes 831 communicated with the through hole 801. The valve 87 is connected to the tail 85 to open or close the through hole 801.
In assembly of the filtering unit 50, as shown in
In assembly of the liquid container 10, as shown in
When the liquid container 10 of the present invention is in operation, the non-filtered liquid streaming through the liquid inlet 25 will first encounter the vortex generator 40 and then enter the upper compartment 221 of the receiving space 22 of the container barrel 20 with a reduced pressure. When the container barrel 20 is washed with cleaning water, the wastewater accumulated at the bottom portion of the container barrel 20 can be discharged out of the container barrel 20 through the liquid discharging holes 831 of the wastewater discharging member 80. Because the wastewater discharging member 80 is located at the bottommost location of the container barrel 20, the wastewater can be completely discharged out of the container barrel 20.
In conclusion, since a pressure reducing device is installed at the liquid inlet of the container barrel of the liquid container of the present invention, the pressure of the liquid entering the container barrel can be effectively depressurized so as to lower the noise due to impact of the liquid on the container barrel. Further, when filter cores are installed inside the container barrel, the pressure reducing device can prevent a filter core that is located adjacent to the liquid inlet from damage due to a high pressure perpetually exerting on the filter core, or prevent the impurities attached on the filter core from washing out from the filter core due to a high pressure exerting on the aforesaid filter core, such that the lifespan of the filter core can be extended and the quality of the filtered liquid can be enhanced. In addition, since the wastewater discharging member is installed at the bottommost location of the container barrel, the wastewater generated after water washing over the container barrel can be completely discharged out of the container barrel.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
