[0027] The activated carbon dust with smaller particle size in the activated carbon filter will flow out with the water when passing water, resulting in the phenomenon of black water. The conventional treatment method is to add a filter membrane at the water outlet of the activated carbon filter element to intercept the activated carbon dust through the filter membrane, thereby avoiding the phenomenon of black water. However, the carbon powder will accumulate on the filter membrane and even block the filter membrane. As the carbon powder accumulates on the filter membrane, the resistance of water flowing through the filter membrane increases, resulting in a decrease in the filtration speed and a slower water output.
[0028] To this end, the utility model proposes a filtration system, which includes an activated carbon filter element and an activated carbon collector. The activated carbon collector is connected to the water outlet side of the activated carbon filter element, and a bypass valve is connected in parallel to the activated carbon collector.
[0029] The parallel bypass valve on the activated carbon collector means that a bypass flow path is set outside the main flow path of the activated carbon collector, and a valve is arranged on the bypass flow path. When the activated carbon collector is full of carbon powder or is blocked, the bypass valve can be opened to allow water to flow through.
[0030] The utility model is connected with an activated carbon collector at the water outlet side of the activated carbon filter element, and the carbon powder in the activated carbon filter element is collected by the activated carbon collector to avoid the occurrence of black water; when the carbon powder collected in the activated carbon collector accumulates and blocks the activated carbon collector, the bypass valve is opened to allow water to flow through, thereby improving the problem of reduced filtration speed caused by the accumulation of carbon powder.
[0031] In addition, compared with conventional systems that require flushing for 15-30 minutes and require professional personnel to perform the flushing operation, the filtration system of the utility model only needs to be flushed for 3-5 minutes when installed and used for the first time, which can save water resources and labor costs.
[0032] It should be noted that when multiple activated carbon filter elements are provided in the filtration system, an activated carbon collector may be provided on the water outlet side of each activated carbon filter element, or an activated carbon collector may be provided only on the water outlet side of the activated carbon filter element at the end.
[0033] In an embodiment of the utility model, the bypass valve is a constant pressure starting valve or a flow control valve.
[0034] A constant pressure start valve is a valve that automatically starts when the system pressure reaches a set value. It contains a pressure sensing device inside, which is connected to the valve core through a mechanical connecting rod or other transmission mechanism. When the system pressure reaches the preset value, the valve can be opened by mechanical force.
[0035] In this embodiment, when carbon powder accumulates in the activated carbon collector and blocks the activated carbon collector, the pressure in the activated carbon filter element will increase. When the pressure in the activated carbon filter element increases to a set value, the constant pressure start valve opens to allow water to flow through.
[0036] A flow control valve is a valve that can monitor fluid flow and automatically start when the fluid flow reaches or exceeds a set value. It contains a flow sensing device inside. When the flow reaches the preset value, the flow sensing device will mechanically trigger the valve core to open.
[0037] In this embodiment, when carbon powder accumulates in the activated carbon collector and blocks the activated carbon collector, the flow on the main flow path of the activated carbon collector will decrease, while the flow on the bypass flow path will increase. When the flow increases to a preset value, the flow control valve opens to allow water to flow through.
[0038] In an embodiment of the utility model, the bypass valve is a solenoid valve; the filtration system also includes a pressure monitoring unit and / or a flow monitoring unit, the pressure monitoring unit is arranged inside the activated carbon filter element, and the flow monitoring unit is arranged on the water outlet side of the activated carbon collector.
[0039] In this embodiment, the bypass flow path can be opened by cooperating with the pressure monitoring unit or the flow monitoring unit and the solenoid valve. When the carbon powder in the activated carbon collector accumulates and blocks the activated carbon collector, the pressure in the activated carbon filter element will gradually increase to the preset value of the pressure monitoring unit, and the solenoid valve will be controlled to open to allow water to flow through; when the carbon powder in the activated carbon collector accumulates and blocks the activated carbon collector, the flow rate on the water outlet side of the activated carbon collector gradually decreases to the preset value of the flow monitoring unit, and the solenoid valve will be controlled to open to allow water to flow through. The pressure monitoring unit can be one of a pressure gauge, a pressure sensor, and a pressure switch, and the flow monitoring unit can be a flow meter.
[0040] In an embodiment of the utility model, the activated carbon collector comprises a shell, one end of the shell is provided with a water inlet, and the other end of the shell is provided with a water outlet, and the water inlet is connected to the water outlet of the activated carbon filter element.
[0041] In the embodiment of the utility model, the activated carbon collector further comprises a membrane assembly, which is arranged in the housing. The membrane assembly can be a conventional filter material such as filter cotton or filter membrane, and this embodiment does not make any specific restrictions.
[0042] In an embodiment of the utility model, the filtration system further comprises a PP cotton filter element, which is connected to the water inlet side of the activated carbon filter element. The PP cotton filter element can be used as a pre-filtration unit to remove large particles such as suspended matter, silt, rust, etc. in the water.
[0043] In an embodiment of the utility model, the filtration system further comprises an RO filter element, which is connected to the water outlet side of the activated carbon collector. The RO filter element further filters the water after being filtered by the activated carbon filter element, and can remove most of the dissolved solids, organic matter, heavy metal ions, bacteria and viruses in the water.
[0044] In an embodiment of the utility model, the filtration system further comprises an alarm unit, which responds when the bypass valve is opened. When the bypass valve is opened, it indicates that the activated carbon collector is blocked, so the alarm unit is provided to remind the user to replace the activated carbon collector. The alarm unit may be a buzzer or a warning light.
[0045] The utility model also provides a water purifier, including the above-mentioned filtration system. The specific configuration of the filtration system refers to the above-mentioned embodiment. Since the water purifier of the utility model adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.
[0046] The following describes the invention in conjunction with specific embodiments.

[0050] The activated carbon collector 300 is connected to the water outlet side of the activated carbon filter element 200, and a constant pressure start valve 400 is connected in parallel to the activated carbon collector 300. Specifically, a main flow path 201 and a bypass flow path 202 are provided on the water outlet side of the activated carbon filter element 200, the activated carbon collector 300 is arranged on the main flow path 201, and the constant pressure start valve 400 is arranged on the bypass flow path 202.

The membrane assembly is arranged in the housing, and the membrane assembly is specifically an ultrafiltration membrane.
[0052] When the filtration system of this embodiment is in operation, the carbon powder in the activated carbon filter element 200 enters the activated carbon collector 300 through the main flow path 201 and is collected, and the carbon powder cannot flow out, thereby avoiding the phenomenon of black water flowing out; when the carbon powder in the activated carbon collector 300 gradually accumulates to the point where the activated carbon collector 300 is blocked, the pressure in the activated carbon filter element 200 will increase. When the pressure gradually increases to the set value of the constant pressure start valve 400, the constant pressure start valve 400 opens to allow water to flow through, thereby improving the problem of reduced filtration speed due to the accumulation of carbon powder.
