by arranging the hot water inlet 142 and the cold water inlet 141 on one side of the mounting seat 110, hot water and cold water are firstly mixed after entering the valve core 100, are not directly contacted with the thermosensitive element 120 at the moment, enter the other side of the mounting seat 110 through the communication hole 111 after being mixed, and are contacted with the thermosensitive element 120 at the moment, so that the situations that the hot water and the cold water are insufficiently mixed when contacting the thermosensitive element 120 and when flowing out from a mixed water outlet are preferably avoided, and the fluctuation of the outlet water temperature when the water pressure changes is preferably avoided;
the thermosensitive element 120 is a paraffin temperature sensing rod 121 or a memory alloy spring 210:
1) When the thermosensitive element 120 is a paraffin temperature sensing rod 121;
the hot water inlet 142 is arranged between the cold water inlet 141 and the mounting base 110, a plurality of communication holes 111 are arranged on the mounting base 110 along the circumferential direction of the paraffin temperature sensing rod 121, and a return spring 220 sleeved outside the paraffin temperature sensing rod 121 is arranged between the lower valve body 130 and the whole body formed by the inner sliding sleeve 150 and the mounting base 110; when the paraffin temperature sensing rod 121 expands with heat, the inner sliding sleeve 150 is driven to move towards the lower valve body 130, so that the water inflow of hot water is reduced, and the water inflow of cold water is increased; when the paraffin wax temperature sensing rod 121 contracts in a cold condition, the inner sliding sleeve 150 is driven to move towards the direction far away from the lower valve body 130, so that the water inflow of hot water is increased, and the water inflow of cold water is reduced;
2) When the thermosensitive element 120 is a memory alloy spring 210;
the cold water inlet 141 is arranged between the hot water inlet 142 and the mounting seat 110, the position of the communication hole 111 is not limited, and the return spring 220 is arranged between the handle sleeve 162 and the mounting seat 110; when the memory alloy spring 210 expands with heat, the inner sliding sleeve 150 is driven to move towards the direction far away from the lower valve body 130, so that the water inflow of hot water is reduced, and the water inflow of cold water is increased; when the memory alloy spring 210 contracts in the cold, the inner sliding sleeve 150 is driven to move towards the lower valve body 130, so that the water inflow of the hot water is increased, and the water inflow of the cold water is reduced.
In this embodiment, one end of the inner sliding sleeve 150 extends into the lower valve body 130 and is attached to the inner sidewall of the lower valve body 130, and the other end extends to a position corresponding to the cold water inlet 141 or the hot water inlet 142 far away from the lower valve body 130 and is attached to the inner sidewall of the middle valve body 140; a first water through hole 151 is formed on the inner sliding sleeve 150 at a position corresponding to the hot water inlet 142 or the cold water inlet 141 near the lower valve body 130,
the other end of the inner sliding sleeve 150 is used for adjusting the water inflow of the corresponding cold water inlet 141 or hot water inlet 142, and the first water through hole 151 is used for adjusting the water inflow of the corresponding hot water inlet 142 or cold water inlet 141.
In this embodiment, the inner sliding sleeve 150 includes a first extension 152 attached to the inner sidewall of the middle valve body 140, a second extension 153 attached to the inner sidewall of the lower valve body 130, and a connecting portion 154 connecting the first extension 152 and the second extension 153;

when the thermosensitive element 120 is the paraffin temperature sensing rod 121 and the inner sliding sleeve 150 moves towards the lower valve body 130, the first water passing hole 151 can slide on the inner side wall of the lower valve body 130 from the state of being completely communicated with the hot water inlet 142 until the first water passing hole 151 is completely blocked by the inner side wall of the lower valve body 130, at this time, the other end of the inner sliding sleeve 150 slides on the inner side wall of the middle valve body 140 from the state of completely blocking the cold water inlet 141 until the cold water inlet 141 is completely opened, thereby realizing the adjustment of the water temperature; when the inner sliding sleeve 150 moves towards the direction far away from the lower valve body 130, because the outer side wall of the lower valve body 130 is fixedly connected with the inner side wall of the middle valve body 140, the inner diameter of the lower valve body 130 is smaller than that of the middle valve body 140, and therefore the second extending portion 153 is closer to the central axis of the valve core 100 than the first extending portion 152, in the process that the first water through hole 151 moves, the water inflow from the hot water inlet 142 flowing in through the first water through hole 151 does not change, at this time, the cold water inlet 141 is gradually blocked under the movement of the other end of the inner sliding sleeve 150, and the water inflow of the cold water inlet 141 is reduced, so that the water temperature is adjusted;
when the thermosensitive element 120 is a memory alloy spring 210, and the inner sliding sleeve 150 moves towards the lower valve body 130, the water inflow of the cold water inlet 141 is reduced, and the water inflow of the hot water inlet 142 is increased; when the inner sliding sleeve 150 moves towards the direction far away from the lower valve body 130, the water inflow of the cold water inlet 141 is unchanged, and the water inflow of the hot water inlet 142 is increased, so that the water temperature is adjusted.
In the aspect of sealing treatment, the first extension portion 152 and the second extension portion 153 may respectively closely adhere to the inner side wall of the middle valve body 140 and the inner side wall of the lower valve body 130 through size design to reduce water flowing out of the valve cartridge 100, and a sealing effect may also be achieved by a conventional method such as providing rubber rings between the first extension portion 152 and the inner side wall of the middle valve body 140 and between the second extension portion 153 and the inner side wall of the lower valve body 130.
