Alternatively, for a structure formed by machining a metal material, a machining opening may be formed in the valve body 11 as well for the convenience of machining. The process ports are communicated with the valve cavity 111, for example, the process ports can penetrate through the wall of the valve cavity 111 through a straight passage, and the connecting passage between the process ports and the valve cavity 111 can form a part of a cold water flow path, and cold water entering from the cold water inlet 112 flows to the valve cavity 111 along the connecting passage. In order to prevent water leakage, the processing opening at the position needs to be sealed by a connecting piece 13.

Meanwhile, since the limiting member 14 is directly inserted into the mounting hole 117 of the valve body 11 from the outside, the limiting member 14 can be inserted after the connecting member 13 is mounted in place; meanwhile, when taking out, the limiting member 14 can be pulled out first, and then the connecting member 13 can be directly pulled out. Therefore, the connecting piece 13 is greatly convenient to disassemble and assemble, and the operation of a user is facilitated, so that the maintenance of the internal structure of the valve body 11 is facilitated.

In an embodiment, the limiting member 14 has an insertion section 141 and an abutting section 142, the insertion section 141 is inserted into the mounting hole 117 and is clamped with the limiting groove 131, and the abutting section 142 abuts against the outer surface of the valve body 11. In this embodiment, the abutting section 142 limits the insertion depth of the limiting member 14, so that the limiting member 14 can be prevented from falling off from the other end of the mounting hole 117.

In one embodiment, the limiting member 14 has two insertion segments 141, and the two insertion segments 141 are respectively connected to the abutting segments 142; the valve body 11 is provided with one mounting hole 117 corresponding to each of the insertion sections 141. Two inserting sections 141 are arranged on the same limiting part 14, so that the limiting position of the connecting piece 13 can be increased, and the installation reliability of the connecting piece 13 is improved. Optionally, the two plug sections 141 are distributed in the radial direction of the communication opening. In order to make the force applied more uniform, the two insertion sections 141 are arranged in parallel, so as to be respectively arranged at two opposite sides of the connecting element 13.

In order to facilitate the clamping connection between the limiting member 14 and the limiting groove 131, in an embodiment, the limiting groove 131 extends along the circumferential direction of the communication opening to form a ring shape, so that no matter how the connecting member 13 rotates, the inserting section 141 of the limiting member 14 can be ensured to be inserted into the limiting groove 131 without being limited by the circumferential position of the connecting member 13. In addition, after the connecting member 13, the limiting member 14 and the valve body 11 are assembled, the connecting member 13 can be rotated to an appropriate angle to be connected to the inner container 20 without being limited by the limiting member 14.

In this embodiment, both the two insertion sections 141 can be clamped with the same limiting groove 131. Optionally, the retaining member 14 is substantially U-shaped. Wherein, butt section 142 can be the vertical bar or be the segmental arc, and the butt section 142 of segmental arc extends along valve body 11 circumference to better laminating with the outer peripheral face of valve body 11, the area of both butts is bigger.

The limiting rib 118 generally extends along the hole edge of the mounting hole 117, and one limiting rib 118 is correspondingly disposed at the hole edge of each mounting hole 117. The side portion of the limiting member 14 is a side portion extending in the axial direction of the mounting hole 117, and after the side portion abuts against the limiting rib 118, the limiting rib 118 can exert a certain guiding effect on the limiting member 14, and prevent the limiting member 14 from deviating from the radial direction of the mounting hole 117.

In order to prevent the limiting member 14 from being separated from the mounting hole 117, in an embodiment, the limiting member 14 and the mounting hole 117 are tightly fitted, that is, they may be in an interference fit or a small clearance fit. Alternatively, in an embodiment, the installation hole 117 is a screw hole, and the limiting member 14 is screwed into the installation hole 117, that is, the insertion section 141 of the limiting member 14 is similar to a bolt.

Alternatively, the temperature-sensing element 122 may be a bulb.

When the mixing valve assembly 10 of the present embodiment is used, a user may adjust a preset water temperature according to actual requirements, during a subsequent use process, a real-time water temperature in the valve cavity 111 may deviate from the preset water temperature, and the temperature sensing element 122 may continuously sense a deviation amount of the water temperature, and drive the valve 121 to generate a displacement according to the deviation amount of the water temperature, so as to correspondingly adjust an opening ratio between the cold water inlet 112 and the hot water inlet 113, so that the deviation amount of the water temperature is compensated in time, and the preset water temperature in the valve cavity 111 is always maintained constant. For example, when the real-time water temperature in the valve cavity 111 is higher than the preset water temperature, the temperature sensing element 122 immediately drives the valve 121 to displace to enlarge the opening degree of the cold water inlet 112, or to reduce the opening degree of the hot water inlet 113 while enlarging the opening degree of the cold water inlet 112, so as to increase the proportion of the cold water flowing into the valve cavity 111, thereby reducing the real-time water temperature to the preset water temperature, so as to obtain the effect of constant water temperature.
