Detailed Description
A plurality of embodiments of the present invention will be described below with reference to the drawings. For the purpose of clarity, numerous implementation details are set forth in the following description. It should be understood, however, that these implementation details are not to be interpreted as limiting the invention. That is, these implementation details are not necessary in some embodiments of the invention. In addition, for the sake of simplicity, some conventional structures and elements are shown in the drawings in a simple schematic manner; and repeated elements will likely be referred to using the same reference numerals.
Fig. 1A is a top view of a filter device 100 according to a first embodiment of the present invention, fig. 1B is a cross-sectional view taken along line 1B-1B of fig. 1A, wherein fig. 1B is a schematic view of a water-stopping state of the filter device 100, and fig. 1C is a schematic view of a water-passing state (i.e., a water-feeding state) of the filter device 100 according to fig. 1B. Referring to fig. 1A to 1C, the filtering apparatus 100 is used for filtering liquid (not shown), such as water, but not limited thereto. The filtering apparatus 100 includes at least one filter module 140, and the filter module 140 includes a filter unit 145, a water inlet 161, a water outlet 181, and a water inlet switch 163.
The water inlet 161 is communicated with the water inlet area 146 of the filter element unit 145, and the water outlet 181 is communicated with the water outlet area 147 of the filter element unit 145. The water inlet switch 163 selectively allows or disallows the water inlet 161 from communicating with the exterior of the filter element module 140 to respectively allow or disallow the flow of liquid into the filter element unit 145. Therefore, the water leakage amount is reduced when the filter element module 140 is replaced, and a water inlet safety mechanism for controlling the water inlet switch 163 by external force is provided.
In detail, the water inlet switch 163 of the filter element module 140 is movably connected to the water inlet 161 or not connected to the outside of the filter element module 140, and the water inlet switch 163 includes a water inlet blocking portion 164. When the water inlet port 161 is not blocked by the water inlet baffle 164, the water inlet port 161 communicates with the outside of the filter element module 140. When the water inlet port 161 is blocked by the water inlet blocking part 164, the water inlet port 161 does not communicate with the outside of the filter element module 140. Therefore, the replacement and disassembly complexity of the filter element module 140 can be reduced.
The filter unit 145 and the water inlet switch 163 may be both columnar, the length direction of the water inlet switch 163 is perpendicular to the length direction of the filter unit 145, and the water inlet switch 163, the water inlet 161, and the water outlet 181 are all located on the same side of the filter unit 145 (in the same direction outside the filter unit 145, i.e., not part of the filter unit 145). Thereby, it is advantageous to use the water inlet switch 163 directly as a section of the water channel, as shown in fig. 1C, the water filtering direction F is the water channel.
Fig. 1D is a schematic cross-sectional view taken along a section line 1D-1D of fig. 1C, and referring to fig. 1A to 1D, the filter module 140 further includes a housing 142 accommodating the filter unit 145, and the housing 142 is cylindrical. The filter element module 140 may further comprise a water outlet switch 183 which is displaceable to connect or disconnect the water outlet 181 to the outside of the filter element module 140 to respectively allow or prohibit the liquid to flow out of the filter element unit 145, the water outlet switch 183 comprising a water outlet baffle 184. When the water outlet port 181 is not blocked by the water outlet blocking portion 184, the water outlet port 181 communicates with the outside of the filter element module 140. When the water outlet port 181 is blocked by the water outlet blocking portion 184, the water outlet port 181 is not communicated with the outside of the filter element module 140. Therefore, the water leakage phenomenon during the replacement of the filter element module 140 can be avoided, and a water inlet and outlet safety mechanism for controlling the water inlet switch 163 and the water outlet switch 183 by external force is provided. Furthermore, the water outlet switch 183 is cylindrical, the length direction of the water outlet switch 183 is perpendicular to the length direction of the filter unit 145, and the water inlet switch 163, the water outlet switch 183, the water inlet 161 and the water outlet 181 are all located on the same side of the filter unit 145.
In the water passing state of the filter apparatus 100 shown in fig. 1C and 1D, the water inlet switch 163 and the water outlet switch 183 are arranged in a straight line and form several portions of a water passage, and the length of the water inlet switch 163 plus the water outlet switch 183 is substantially equal to the width of the housing 142 in the width direction of the filter element unit 145. The water inlet baffle 164 of the water inlet switch 163 is used as a separation wall to completely separate the water inlet area and the water outlet area of the water channel, the water channel formed by the O-ring of the water inlet switch 163 is used for the liquid to pass through, the opening 165 of the water inlet switch 163 is at least partially aligned with and communicated with the water inlet 161 (the communication area is shown as the intersection area of the opening 165 and the water inlet 161 in fig. 1D), so that the liquid flows into the water inlet area 146 of the filter core unit 145 from the opening 165 and the water inlet 161. The water outlet blocking portion 184 is an O-ring portion of the water outlet switch 183, an opening 185 of the water outlet switch 183 is disposed on the annular housing of the water outlet blocking portion 184, the opening 185 of the water outlet switch 183 is at least partially aligned with and communicated with the water outlet 181 (the communication area is the intersection area of the opening 185 and the water outlet 181 in the enlarged view of fig. 1D, wherein the inverted-oblique-bar area in the enlarged view of fig. 1D indicates the water outlet area 147 of the filter core unit 145, the sprinkling point area indicates the water outlet blocking portion 184, and the cross area indicates other solid structures), so that the liquid flows from the water outlet area 147 of the filter core unit 145 through the water outlet 181 and the opening 185, and then flows into a water channel formed by the O-ring-shaped water outlet blocking portion 184.
Fig. 1E shows a side view of the filter device 100 according to fig. 1A, and fig. 1E is a left side view of the filter device 100 in fig. 1C. Referring to fig. 1A to 1E, the number of the filter element modules 140 may be at least two, and the water outlet switch 183 of one of the filter element modules 140 is connected to and abutted against the water inlet switch 163 of another of the filter element modules 140. Therefore, the filter element modules 140 have a modularized engineering design of quick disassembly and connection in pairs, and the modularized filter element modules 140 in the filter device 100 can be expanded infinitely. For example, the filter apparatus 100 of fig. 1A-1E includes three filter element modules 140, and the liquid flows into the filter apparatus 100 from the water inlet switch 163 of the rightmost filter element module 140 of fig. 1C, wherein the water outlet switch 183 of one of the two adjacent filter element modules 140 is connected to and abuts against the water inlet switch 163 of the other of the two adjacent filter element modules 140. The water inlet switch 163 and the water outlet switch 183 of the three filter element modules 140 of the filter device 100 are alternately arranged along a straight line, so that the liquid sequentially flows through the filter element modules 140 from the rightmost side to the leftmost side. In fig. 1E, the water inlet switch 163 and the water outlet switch 183 of the three filter element modules 140 are disposed in the right water channel in fig. 1E, and can be connected to the right and left water channels in fig. 1E through the water channel connectors (not shown) in the filtering apparatus 100, so that the filtered liquid flows out of the filtering apparatus 100 through the left water channel in fig. 1E.
Compared with the filtering device in the prior art, the water channel of the shell of the filtering device is communicated with the water channels of the two adjacent filter element modules, namely the water channel for filtering is arranged on each filter element module, the water channel for communicating the two adjacent filter element modules is arranged on the shell of the filtering device, and the water-stopping or water-leakage-preventing mechanism is arranged on the shell of the filtering device, so when the filter element modules are replaced, liquid in the water channel of the filter element modules disconnected from the shell of the filtering device can be poured out along with the water channel, and the inconvenience and trouble of replacing the sprinkler filter element modules are brought. In the filtering apparatus 100 according to the present invention, the water-stopping or water-leakage-preventing mechanism is directly disposed on the water channel of each replaceable filter element module 140, so as to effectively avoid the problem of liquid spraying when replacing the filter element module 140.
Referring to fig. 1B to fig. 1D, the water inlet switch 163 and the water outlet switch 183 of the filter element module 140 are linked, and the water inlet blocking portion 164 and the water outlet blocking portion 184 are disposed inside the filter element module 140. This simplifies the mechanical design and switching of the water inlet switch 163 and the water outlet switch 183. For example, the water inlet switch 163 and the water outlet switch 183 of the filter device 100 in fig. 1B to 1D may be two parts of the same structure, or two structures connected, abutted or coupled to each other. As shown in fig. 1C, pushing left from the water inlet switch 163 of the rightmost filter element module 140 in fig. 1C opens the water channel, and pushing right from the water outlet switch 183 of the leftmost filter element module 140 in fig. 1C closes the water channel. In addition, the filtering apparatus 100 may further include a hydraulic pressure detecting unit or a raw water turbidity detecting unit, and when the detected hydraulic pressure or raw water turbidity reaches a threshold value, the water may be automatically cut off (i.e., switched to the water stop state shown in fig. 1B) to avoid damage to the filtering material.
