Specifically, in the present embodiment, the flow valve 700 is a triangular valve; the inflow conduit 600 is a braided hose.

Referring to fig. 3 and 4, the filter 100 in an embodiment includes a filter shell 110, a filter element 120 and a regulating assembly 130, wherein a receiving cavity 111 is formed in the filter shell 110, a water inlet 140 and a water outlet 150 are formed on the filter shell 110, and the water inlet 140 is communicated with the receiving cavity 111; the filter element 120 is disposed in the accommodating cavity 111, a filter cavity 121 is formed in the filter element 120, and the filter cavity 121 is communicated with the water outlet 150.

Referring to fig. 8, specifically, the adjusting assembly 130 includes an adjusting member 131 and a sliding member 132, the adjusting member 131 is disposed in the accommodating cavity 111 of the filter housing 110, an accommodating cavity 135 is formed on the adjusting member 131, the accommodating cavity 135 penetrates through one end of the adjusting member 131 to form an adjusting opening 136, and the adjusting opening 136 is communicated with the accommodating cavity 111; the sliding member 132 is disposed in the accommodating cavity 135 through the adjusting opening 136, the sliding member 132 is in sealing contact with the inner wall of the accommodating cavity 135, and the sliding member 132 can move in the accommodating cavity 135 towards or away from the adjusting opening 136.

As shown in fig. 4, the water flows into the receiving cavity 111 through the water inlet 140, and the water flows into the receiving cavity 111 through the filter cavity 121 to the water outlet 150. If the filter 100 is in a cold environment, the water in the housing cavity 111 is very likely to freeze. The volume expansion of the ice blocks extrudes the filter shell 200, so that the filter shell 200 expands and bursts, and safety accidents occur. In contrast, in the filter 100 of the present embodiment, when the water in the accommodating chamber 111 freezes, the ice blocks press the space in the accommodating chamber 111, and the pressure in the accommodating chamber 111 changes. At this time, the slider 132 can move in a direction away from the adjustment port 136 by the pressure difference after the pressure change, so that the size of the space of the housing chamber 111 is adjusted to cancel the pressure increased in the housing chamber 111 by the freezing. Therefore, the present embodiment also has a certain explosion-proof function, and greatly expands the use scenes and safety of the filter 100.

When the water inlet 140 is suddenly stopped and closed, the flow rate of water is suddenly changed, and thus a water hammer phenomenon is generated. The water pressure shock wave of the water hammer phenomenon is transmitted into the receiving cavity 111 from the water inlet 140, so that the water pressure in the receiving cavity 111 is obviously changed. Meanwhile, when the water outlet 150 is suddenly stopped and suddenly closed, a water hammer phenomenon is formed at the water outlet 150, a water pressure shock wave generated by the water hammer phenomenon is further transmitted to the adjusting member 131, and a certain pressure difference exists between the pressure in the accommodating cavity 135 of the adjusting member 131 and the outside due to the sealing contact between the sliding member 132 and the inner wall of the accommodating cavity 135. Under the action of pressure difference, water can push the sliding part 132 to shrink towards the inside of the accommodating cavity 135 from the side of the adjusting port 136, so that the part of the accommodating cavity 135, located on the side of the adjusting port 136, of the sliding part 132, of the adjusting part 131 is communicated with the accommodating cavity 111 of the filter shell 110, and water pressure shock waves flow towards the part of the accommodating cavity 135 through the adjusting port 136, so that the accommodating space of water in the accommodating cavity 111 is enlarged, repeated oscillation of the water pressure shock waves in the filter element 120 is avoided, and safety accidents such as bursting and leakage caused by overlarge internal water pressure are avoided. The sliding part 132 moves towards or away from the adjusting opening 136 in the accommodating cavity 135, so that the size of the accommodating cavity 111 is adjusted, the water pressure shock wave is guided, the water pressure shock wave generated by the water hammer phenomenon is offset, and the safety of the filter 100 is ensured. When the water pressure in the filter 100 is leveled, the pressure in the accommodating cavity 135 is significantly greater than the water pressure outside the accommodating cavity 135, and the sliding member 132 returns to the initial position at the adjusting opening 136 along with the pressure difference, so as to ensure the next use of the adjusting member 131, thereby improving the reliability of the filter 100.

Referring to fig. 4 and 8, further, the accommodating chamber 135 is filled with an inert gas. The type of the inert gas in the accommodating cavity 135 can be selected or mixed and filled with the inert gas according to the water pressure in the actual accommodating cavity 111. The inert gas is filled in the accommodating cavity 135 to balance the pressure inside and outside the accommodating cavity 135, so that the sliding member 132 can be balanced at the adjusting opening 136 under a normal state. Meanwhile, if a small amount of inert gas leaks, the environment and the human body are not harmed. In other embodiments, the receiving cavity 135 is filled with compressed air.

In one embodiment, the adjusting assembly 130 of the filter 100 further includes an elastic member 133, the elastic member 133 is disposed in the accommodating cavity 135, one end of the elastic member 133 abuts against the bottom wall of the accommodating cavity 135, and the other end is connected to the sliding member 132. When the external water pressure pushes the sliding member 132 to move toward the bottom wall of the accommodating cavity 135, the elastic member 133 is compressed under the pushing of the sliding member 132; when the external water pressure is leveled, the sliding member 132 moves to the initial position at the regulating port 136 by the pressure difference and the elastic force of the elastic member 133. As the pressure differential approaches zero, the urging of the slide 132 by the pressure differential is gradually reduced. However, the elastic member 133 is disposed in the accommodating cavity 135, and the elastic force of the elastic member 133 will continue to push the sliding member 132 to reset as a supplementary force to the pressure when the pressure difference approaches zero. The functional stability of the adjustment assembly 130 is improved, and the agility of the adjustment assembly 130 is also improved.

Specifically, a fixing groove is formed in a bottom wall of the accommodating cavity 135, and one end of the elastic member 133 is disposed in the fixing groove. Because one end of the elastic member 133 is disposed in the fixing groove, the elastic member 133 can be stably supported during the compression and stretching processes, and the stability and reliability of the function of the adjusting assembly 130 are improved.

Further, the sliding member 132 is provided with a first groove, and one end of the elastic member 133 is sleeved in the first groove. Because the elastic member 133 can be sleeved on the first groove of the sliding member 132, the connection between the elastic member 133 and the sliding member 132 is more stable, the contact area between the elastic member 133 and the sliding member 132 is also increased, the thrust of the elastic member 133 to the sliding member 132 or the pressure of the sliding member 132 to the elastic member 133 can be completely transmitted, and the stability and reliability of the function of the adjusting assembly 130 are ensured.

In one embodiment, the adjusting assembly 130 of the filter 100 further includes a second sealing member 137, the second sealing member 137 is disposed on the sliding member 132, and the second sealing member 137 is located between the sliding member 132 and the inner wall of the accommodating cavity 135.
