Detailed Description
The invention will be further illustrated with reference to specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.
The filter element 1 referred to in this patent is a generic term for a member having a filtering function, and includes, but is not limited to, a filter flask, a filter member (e.g., an activated carbon rod filter element 15, a reverse osmosis membrane 81, etc.), and other support members.
Referring to fig. 1 to 10, embodiment 1, this embodiment 1 provides a filter cartridge and pressure unit integrated filter device, including a filter cartridge 1 and a pressure unit 2, where the filter cartridge 1 and the pressure unit 2 are connected to form an integrated filter device.
By "the filter element 1 and the pressure unit 2 are integrally connected" it is meant that the filter element 1 and the pressure unit 2 are connected together, i.e. the filter element 1 and the pressure unit 2 are integrated, no additional connecting parts, such as pipe connectors, pipelines, etc., are needed between the filter element 1 and the pressure unit 2, the filtering space 11 of the filter element 1 is communicated with the water storage space 21 of the pressure unit 2, and as long as water enters the filtering space 11 and/or the water storage space 21, the operations of filtering and increasing the water storage for the water storage space 21 of the pressure unit 2 can be completed. This filter core and pressure unit integration filter equipment because of the integrated design, can be more miniaturized, and the rational utilization space, occupation space is littleer because of having left out and needing extra connecting piece (such as pipe connector, pipeline etc.), practices thrift the cost, also can avoid through the secondary pollution that extra connecting piece produced and reduce the possibility of leaking.
A filtering space 11 for filtering water in the filter element 1; the pressure unit 2 comprises a water storage space 21 for storing water and pressurizing and a pressure space 22 for providing pressure to the water storage space 21; the filtering space 11 is communicated with the water storage space 21.
Preferably, the power of the water source flowing out of the pressure unit in the water storage space 21 (i.e. the water supply power) comes from the air power provided by the pressure space 22, or comes from the spring power provided by the pressure space 22, or comes from the water pressure power provided by the pressure difference between the water storage space 21 and the outside.
The water delivery power refers to the power or pressure of the water in the water storage space 21 flowing out of the pressure unit 2, such as the pressure provided by the pressure space 22 in the pressure unit 2 to the water storage space, which helps the water in the water storage space 21 to flow out of the pressure unit 2. For example, a pressure difference between the water pressure in the water storage space 21 and the external water pressure is utilized, and the pressure difference helps the water in the water storage space 21 to flow out of the pressure unit 2. The pressure space 22 in the pressure unit 2 supplies pressure to the water storage space 21 in three modes, i.e., an air mode, a spring mode, and a water pressure mode.
The air type is that the pressure space 22 is communicated with the atmosphere or an air charging device, and the pressure inside the pressure space 22 is adjusted by the atmospheric pressure or by adjusting the gas pressure inside the pressure space 22, so as to achieve the purpose of adjusting the pressure force provided by the pressure space 22 to the water storage space 21.

The water storage space 21 increases its internal water source with the increase of its internal pressure, the pressure space 22 is squeezed, for example, by the first partition 23 and/or the second partition 24, after the pressure in the pressure space 22 increases, when the pressure in the water storage space 21 and the pressure space 22 reach a pressure balance, water is stopped from entering the water storage space 21 until the pressure of the water inlet 31 decreases, that is, the pressure difference between the water inlet 31 and the water outlet 32 is smaller than the pressure value of the water storage space 21, the water source in the water storage space 21 flows out of the integrated filtering apparatus through the water inlet 31 and/or the water outlet 32, at this time, the pressure space 22 applies pressure to the water storage space 21, that is, the water storage space 21 is compressed by the first partition 23 and/or the second partition 24, so as to help the water source in the water storage space 21 to discharge the integrated filtering apparatus, until the pressure in the water storage, the water storage space 21 stops the water discharge. Preferably, in the water inlet and/or outlet process, the water source in the water storage space 21 is filtered by the filter element 1, so as to further improve the quality of the water source in the water storage space 21, such as sterilization, taste improvement, particle reduction and other water purification effects.
