It is easy to cause excessive local pressure, which is prone to the risk of water leakage. By making the width of the water flow channel 1211 greater than or equal to 8 mm and less than or equal to 10 mm, and the depth of the water flow channel 1211 greater than or equal to 8 mm and less than or equal to 10 mm, large-area flow can be avoided while meeting the flow requirements of the water system. The local pressure is too high, and there is a risk of water leakage. The bottom of the water flow channel 1211 can be properly rounded to further avoid excessive local pressure in the flow channel.

Combined with the above-mentioned embodiment of the waterway box 121 including the front cover 1213 and the rear cover 1214 connected by welding, further, please refer to FIG. 8 , the front cover 1213 is provided with the first welding rib 10 , and the rear cover 1214 corresponds to the first welding rib 10 is provided with a second welding rib 20, the width of the first welding rib 10 is greater than or equal to 3.5mm, and less than or equal to 4.5mm; and/or, the width of the second welding rib 20 is greater than or equal to 3.5mm, and less than or equal to 4.5mm.

In this embodiment, the width of the first welding rib 10 may specifically be 4 mm, and the width of the second welding rib 20 may specifically be 4 mm. If the width of the first welding rib 10 is less than 3.5 mm and the width of the second welding rib 20 is less than 3.5 mm, the welding strength cannot be guaranteed, and the risk of water leakage is likely to occur. If the width of the first welding rib 10 is greater than 4.5 mm and the width of the second welding rib 20 is greater than 4.5 mm, the cross-sectional area of the water flow channel 1211 will be reduced, and the flow demand of the water system cannot be guaranteed. By making the width of the first welding rib 10 greater than or equal to 3.5 mm and less than or equal to 4.5 mm, and the width of the second welding rib 20 being greater than or equal to 3.5 mm and less than or equal to 4.5 mm, the flow rate of the water system can be guaranteed. At the same time as required, the welding strength of the front cover 1213 and the rear cover 1214 can be ensured, thereby reducing or avoiding water leakage. The first welding rib 10 and the second welding rib 20 can be properly rounded to fill the welding flash.

Further, referring to FIG. 8 again, a welding area 1216 is formed between the first welding rib 10 and the second welding rib 20 , and the depth of the welding area 1216 is greater than or equal to 2 mm and less than or equal to 3 mm. If the depth of the welding area 1216 is made less than 2 mm, the welding strength cannot be guaranteed, and the risk of water leakage is likely to occur. If the depth of the welding area 1216 is made larger than 3 mm, the cross-sectional area of the water flow channel 1211 will be increased, and the large-area flow channel is likely to cause excessive local pressure and a risk of water leakage. By making the depth of the welding area 1216 greater than or equal to 2 mm and less than or equal to 3 mm, the welding strength of the front cover 1213 and the rear cover 1214 can be ensured, and the local pressure caused by the large-area flow channel can be avoided, and the front cover 1213 can be further avoided. There is a risk of water leakage between it and the back cover 1214.
