Further, as shown in fig. 1 to 11, the water inlet channel 220 and the water outlet channel 230 are disposed on the same axis, and the wastewater channel 240 and the water outlet channel 230 are disposed at an included angle, so that an installer can align and install the water inlet channel and the water outlet channel more easily when connecting the water inlet channel and the water outlet channel, bending and torsion in the process of connecting the pipes are reduced, the installation difficulty is reduced, and the installation efficiency is improved.
In this embodiment, as shown in fig. 1, a plurality of supporting ribs 150 are disposed on the inner sidewall of the bottom of the bottle body 100 at intervals along the circumferential direction, a limiting step 160 is disposed on each of the plurality of supporting ribs 150 to form a mounting platform through the plurality of limiting steps 160, the lower end of the filter element 120 is abutted to the mounting platform, a containing space 170 is formed between the lower end of the filter element 120 and the bottom wall of the bottle body 100, and an air bag 180 is disposed in the containing space 170.
In one possible implementation, a mounting column is disposed between the bottom of the filter element 120 and the bottom wall of the bottle body 100, an air bag 180 is disposed on the mounting column, and a mounting hole is formed in the middle of the air bag 180, so that the air bag 180 is sleeved on the mounting column through the mounting hole to perform mounting.
Preferably, the volume of the air bag 180 under the atmospheric pressure is approximately 0.75-1.25 times of the volume of the raw water cavity 130, and the air bag 180 is arranged so that the expansion volume of the air bag 180 is similar to the volume of the raw water cavity 130, so that the air bag 180 can discharge sewage equivalent to the expansion volume of the sewage out of the filter flask from the waste water channel 240 in the back flushing state in a decompression expansion way, and in other embodiments, an external pressure tank can be arranged at one side of the water outlet channel 230 to provide assistance for back flushing.
When water is stopped, the air bag 180 is compressed under the action of water pressure, so that the impact of water hammer on the filter bottle can be effectively eliminated.
The volume of the raw water cavity 130 is about 1/10 of the whole volume of the filter element 120, the water capacity of the raw water cavity 130 is about 150ml, the volume is smaller and is similar to the contracted volume of the air bag 180, so that impurities and sewage in the raw water cavity 130 can be just discharged cleanly by using the pressure generated by the decompression expansion of the air bag 180, and the impurities and sewage can be discharged cleanly without excessive waste of flushing water.
The assembly steps of the utility model are that firstly, the air bag 180 is positioned and installed at the bottom of the bottle body 100, then the filter element 120 is vertically placed in the bottle body 100, the valve body 300 is aligned and arranged at the top of the filter element 120, then the bottle cap 200 is screwed on the bottle body 100, the top of the valve body 300 is penetrated through the avoiding hole 250 in the bottle cap 200, and finally the screwing part 320 is installed at the top of the valve body 300.
From the above description, it can be seen that the above-mentioned embodiments of the present utility model achieve the technical effects that the filter bottle is in the filtering state or the first state by rotating the valve body 300, in the filtering state, the valve body 300 communicates the water inlet channel 220 with the raw water cavity 130 and communicates the water outlet channel 230 with the water purifying cavity 140, so that raw water flowing into the water inlet channel 220 is filtered from the raw water cavity 130 to the water purifying cavity 140, i.e. from inside to outside, filtered purified water flows out of the water outlet channel 230 for daily life use of a user, in the first state, the water inlet channel 220 is stopped from the raw water cavity 130 and/or the water outlet channel 230 is stopped from the water purifying cavity 140 by the valve body 300, so that water is stopped between the bottle body 100 and the bottle cap 200, and thus the filter cartridge 120 is conveniently unscrewed for replacement, and thus the valve body 300 can further control flowing water in the filter bottle, the stopping function is integrated inside the filter bottle, no additional valve is required to be installed on the water inlet channel 220 and the water outlet channel 230, the whole structure is more compact, external pipeline accessories are reduced, the pipeline installation space is saved, the pipeline installation connection point is reduced, the cost is easy, the cost is low, the production is easy, and the cost is easy, and the production is easy, and the cost is easy to maintain.
