[0028] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0029] Reference Figure 1 and Figure 2 The embodiments of this application provide a waterway module.

[0030] The water circuit module includes: a housing 200 and a pressure balancing component 100.

[0031] The housing 200 contains a first water channel 210 and a second water channel 220. A pressure balancing component 100 is disposed in a receiving cavity 250, which connects to the first water channel 210 and the second water channel 220. The pressure balancing component 100 includes a fixed component 110 and a movable component 120. The fixed component 110 is fixedly installed in the receiving cavity 250, and the movable component 120 is movably connected to the interior of the fixed component 110. The fixed component 110 and the movable component 120 form a third water channel 230 and a fourth water channel 240. The third water channel 230 connects to the first water channel 210, and the fourth water channel 240 connects to the second water channel 220. The fixed component 110 is provided with a first water inlet 111 and a second water inlet 120. The movable component 120 is provided with a third water inlet 121 connected to the third water channel 230 and a fourth water inlet 122 connected to the fourth water channel 240. The first water inlet 111 and the third water inlet 121 are in corresponding positions, and the second water inlet 112 and the fourth water inlet 122 are in corresponding positions. The size of the water inlet of the third water channel 230 formed by the misalignment of the first water inlet 111 and the third water inlet 121 is adjusted by moving the movable component 120, and the size of the water inlet of the fourth water channel 240 formed by the misalignment of the second water inlet 112 and the fourth water inlet 122 is also adjusted.

[0032] Reference Figure 3 In this embodiment, the first water channel 210 is a cold water channel, and the second water channel 220 is a hot water channel. The first water channel 210 and the second water channel 220 are not connected except at the receiving cavity 250. When the pressure balancing member 100 is removed from the receiving cavity 250, the first water channel 210 and the second water channel 220 connect at the location within the receiving cavity 250. However, the movable part 120 of the pressure balancing member 100 is provided with a partition 127, separating the third water channel 230 and the fourth water channel 240. When the third waterway 230 is connected to the first waterway 210, cold water flows through the first waterway 210 into the third waterway 230 of the pressure balancing component 100, and continues to flow along the first waterway 210 after exiting the third waterway 230. When the fourth waterway 240 is connected to the second waterway 220, hot water flows through the second waterway 220 into the fourth waterway 240 of the pressure balancing component 100, and continues to flow along the second waterway 220 after exiting the fourth waterway 240.

[0033] When the first inlet 111 and the third inlet 121 are misaligned and overlapped, the inlet of the third waterway 230 formed by the misalignment of the first inlet 111 and the third inlet 121 is open. When the first inlet 111 and the third inlet 121 do not overlap, the inlet of the third waterway 230 formed by the misalignment of the first inlet 111 and the third inlet 121 is completely closed. The larger the misalignment and overlap of the first inlet 111 and the third inlet 121, the larger the inlet of the third waterway 230 formed by the misalignment of the first inlet 111 and the third inlet 121. The smaller the misalignment and overlap of the first inlet 111 and the third inlet 121, the smaller the inlet of the third waterway 230 formed by the misalignment of the first inlet 111 and the third inlet 121. When the second inlet 112 and the fourth inlet 122 are misaligned and overlapped, the inlet of the fourth waterway 240 formed by the misalignment of the second inlet 112 and the fourth inlet 122 is open. When the second inlet 112 and the fourth inlet 122 do not overlap, the inlet of the fourth waterway 240 formed by the misalignment of the second inlet 112 and the fourth inlet 122 is completely closed. The larger the misalignment and overlap of the second inlet 112 and the fourth inlet 122, the larger the inlet of the fourth waterway 240 formed by the misalignment of the second inlet 112 and the fourth inlet 122. The smaller the misalignment and overlap of the second inlet 112 and the fourth inlet 122, the smaller the inlet of the fourth waterway 240 formed by the misalignment of the second inlet 112 and the fourth inlet 122.

[0034] When the water flow rate through the third channel 230 is different from the water flow rate through the fourth channel 240, the pressure on the baffle 127 in the third channel 230 is different from the pressure in the fourth channel 240. When the water flow rate through the third channel 230 is greater than the water flow rate through the fourth channel 240, the pressure on the baffle 127 in the third channel 230 is greater than the pressure in the fourth channel 240. The water pressure causes the movable part 120 to move towards the fourth channel 240, increasing the misalignment distance between the first inlet 111 and the third inlet 121, decreasing the size of the inlet corresponding to the third channel 230, decreasing the misalignment distance between the second inlet 112 and the fourth inlet 122, and increasing the size of the inlet corresponding to the fourth channel 240. Through the movement of the movable part 120, the water flow rate through the third channel 230 gradually becomes the same as the water flow rate through the fourth channel 240. When the water flow rate through the third waterway 230 is less than the water flow rate through the fourth waterway 240, the pressure on the baffle 127 in the third waterway 230 is less than the pressure on the fourth waterway 240. The water pressure causes the movable part 120 to move towards the third waterway 230, which reduces the misalignment distance between the first inlet 111 and the third inlet 121, increases the size of the inlet corresponding to the third waterway 230, increases the misalignment distance between the second inlet 112 and the fourth inlet 122, and decreases the size of the inlet corresponding to the fourth waterway 240. Through the movement of the movable part 120, the water flow rate through the third waterway 230 gradually becomes the same as the water flow rate through the fourth waterway 240.

[0035] Reference Figure 4 , Figure 5 and Figure 6 The fixing member 110 is provided with a first inlet 111, a second inlet 112, a first outlet 113, a second outlet 114, and a first cavity 115. The first inlet 111, the second inlet 112, the first outlet 113, and the second outlet 114 are connected to the first cavity 115. The movable member 120 is disposed within the first cavity 115. The first inlet 111 and the second inlet 112 are disposed on the outer wall of the fixing member 110. The first inlet 111 is connected to the first water channel 210, and the second inlet 112 is connected to the second water channel 220. The first outlet 113 and the second outlet 114 are disposed opposite to each other.

[0036] Reference Figure 4 , Figure 5 and reference Figure 7The movable component 120 is provided with a third water inlet 121, a fourth water inlet 122, a third water outlet 123, a fourth water outlet 124, a second cavity 125, and a third cavity 126. The second cavity 125 and the third cavity 126 are separated by a partition 127. The third water inlet 121 and the third water outlet 123 are connected to the second cavity 125, and the fourth water inlet 122 and the fourth water outlet 124 are connected to the third cavity 126. The position of the third water inlet 121 corresponds to the position of the first water inlet 111, and the position of the fourth water inlet 122 corresponds to the position of the second water inlet 112. The position of the third water outlet 123 corresponds to the position of the first water outlet 113, and the position of the fourth water outlet 124 corresponds to the position of the second water outlet 114.

[0037] The first inlet 111, the third inlet 121, the second cavity 125, the first outlet 113, and the third outlet 123 form the third waterway 230; the second inlet 112, the fourth inlet 122, the third cavity 126, the second outlet 114, and the fourth outlet 124 form the fourth waterway 240.

[0038] Water flows through the first waterway 210, passes through the first inlet 111 of the fixed member 110, and passes through the third inlet 121 of the movable member 120. The first inlet 111 and the third inlet 121 are misaligned to form the inlet of the third waterway 230. Water enters the second cavity 125 from the third inlet 121, flows through the second cavity 125, and the water flowing through the second cavity 125 exerts water pressure on the partition 127. Water flows out from the third outlet 123 of the movable member 120, and then flows out from the first outlet 113 of the fixed member 110 back to the first waterway 210.

[0039] Water flows through the second waterway 220, passes through the second inlet 112 of the fixed member 110, and passes through the fourth inlet 122 of the movable member 120. The second inlet 112 and the fourth inlet 122 are misaligned to form the inlet of the fourth waterway 240. Water enters the third cavity 126 from the fourth inlet 122, flows through the third cavity 126, and the water flowing through the third cavity 126 exerts water pressure on the partition 127. Water flows out from the fourth outlet 124 of the movable member 120, and then flows back to the second waterway 220 from the second outlet 114 of the fixed member 110.

[0040] When the water flow rate through the second cavity 125 is greater than the water flow rate through the third cavity 126, the pressure on the baffle 127 in the second cavity 125 is greater than the pressure in the third cavity 126. The water pressure causes the movable part 120 to move towards the third cavity 126, which increases the misalignment distance between the first inlet 111 and the third inlet 121, reduces the inlet corresponding to the third water channel 230, reduces the misalignment distance between the second inlet 112 and the fourth inlet 122, and increases the inlet corresponding to the fourth water channel 240. Through the movement of the movable part 120, the water flow rate through the second cavity 125 gradually becomes the same as the water flow rate through the third cavity 126. When the water flow rate through the second cavity 125 is less than the water flow rate through the third cavity 126, the pressure on the baffle 127 in the second cavity 125 is less than the pressure on the third cavity 126. The water pressure causes the movable part 120 to move towards the second cavity 125, thereby reducing the misalignment distance between the first inlet 111 and the third inlet 121, increasing the inlet corresponding to the third water channel 230, increasing the misalignment distance between the second inlet 112 and the fourth inlet 122, and decreasing the inlet corresponding to the fourth water channel 240. Through the movement of the movable part 120, the water flow rate through the second cavity 125 gradually becomes the same as the water flow rate through the third cavity 126.

[0041] Reference Figure 3 The receiving cavity 250 is provided with a first recess 251, and the fixing member 110 is engaged with the first recess 251. The side wall of the first recess 251 abuts against the outer side of the fixing member 110 without gap, the bottom of the first recess 251 abuts against the outer side of the fixing member 110 without gap, and the cavity wall of the first cavity 115 abuts against the outer side of the fixing member 110 without gap, so that the water in the first water channel 210 can only pass through the first water inlet 111 of the fixing member 110, and the water in the second water channel 220 can only pass through the second water inlet 112 of the fixing member 110.

[0042] The receiving cavity 250 is provided with a second recess 252 and a third recess 253. The first recess 251, the second recess 252 and the third recess 253 are arranged sequentially from the direction close to the pressure balancer 100 to the direction away from the pressure balancer 100, and the first recess 251, the second recess 252 and the third recess 253 gradually decrease in size from the direction close to the pressure balancer 100 to the direction away from the pressure balancer 100, forming a stepped shape.

[0043] The second recess 252 is used to limit the range of motion of the movable part 120, prevent the movable part 120 from detaching from the fixed part 110, and prevent the first water inlet 111 and the third water inlet 121 from being completely misaligned, thus closing the water inlet of the third water channel 230 formed by the first water inlet 111 and the third water inlet 121, or the second water inlet 112 and the fourth water inlet 122 from being completely misaligned, thus closing the water inlet of the fourth water channel 240 formed by the second water inlet 112 and the fourth water inlet 122. When the movable part 120 abuts against the second recess 252, the first water inlet 111 and the third water inlet 121 will partially overlap, thereby ensuring that the water inlet of the third water channel 230 formed by the first water inlet 111 and the third water inlet 121 is open; the second water inlet 112 and the fourth water inlet 122 will partially overlap, thereby ensuring that the water inlet of the fourth water channel 240 formed by the second water inlet 112 and the fourth water inlet 122 is open.

[0044] When the movable member 120 abuts against the second recess 252, a water channel is formed between the movable member 120 and the third recess 253. Water flowing out of the first outlet 113 flows through the water channel formed between the movable member 120 and the third recess 253 on one side. Water flowing out of the second outlet 114 flows through the water channel formed between the movable member 120 and the third recess 253 on the other side.

[0045] The pressure balancing component 100 has a first recess 251, a second recess 252 and a third recess 253 on both sides.

[0046] Water flows through the first waterway 210, passes through the first inlet 111 of the fixed member 110, and passes through the third inlet 121 of the movable member 120. The first inlet 111 and the third inlet 121 are misaligned to form the inlet of the third waterway 230. Water enters the second cavity 125 from the third inlet 121, flows through the second cavity 125, flows out from the third outlet 123 of the movable member 120, and then flows out from the first outlet 113 of the fixed member 110. Water then flows through the water passage between the pressure balancing member 100 and the second and third recessed platforms 252 and 253.

[0047] Water flows through the second waterway 220, passes through the second inlet 112 of the fixed member 110, and passes through the fourth inlet 122 of the movable member 120. The second inlet 112 and the fourth inlet 122 are misaligned to form the inlet of the fourth waterway 240. Water enters the third cavity 126 from the fourth inlet 122, flows through the third cavity 126, and the water flowing through the third cavity 126 exerts water pressure on the partition 127. Water flows out from the fourth outlet 124 of the movable member 120, and then flows back to the second waterway 220 from the second outlet 114 of the fixed member 110.

[0048] An embodiment of this application provides a shower faucet, including the water circuit module described above.

[0049] The above is a detailed description of the preferred embodiments of this application, but this application is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this application, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
