Technical Field
[0001] The utility model relates to the technical field of water heating devices, in particular to a cap structure for instant hot water faucets. Background Art
[0002] Instant electric water faucets can heat the water quickly. Due to the convenience of taking hot water, their use has become more and more common. Usually, an inner tank is set in the faucet, and the inner tank includes an upper cover, a heating water chamber, and a lower seat. A water inlet assembly is set in the lower seat to let water in, and the water is heated by the heating water chamber and finally flows out from the water outlet pipe at the upper cover. A main control assembly is also set in the lower seat to control the heating power and connect the power supply. An extension seat is provided on one side of the lower seat, and a water flow regulating mechanism is provided at the extension seat. The handle of the water flow regulating mechanism is rotated to adjust the water flow size.
[0003] The caps of current instant electric water faucets are made of plastic or other deformable materials, which will cause tensile force on the cap itself due to the threaded connection structure when the handle is installed, causing the cap to deform after installation. The deformed cap will not be on the same axis as the valve stem when installed. The eccentricity of the cap will interfere with other components, causing the valve stem to be blocked and ultimately affecting the accuracy of water flow regulation. Summary of the invention
[0004] The problem to be solved by the utility model is: to provide a cap structure for an instant water faucet, so as to solve the problem that the cap is made of plastic or other materials that may be deformed, resulting in a tensile force on the cap itself due to the threaded connection structure when the handle is installed, causing the cap to deform after installation, and the deformation of the cap will make the cap not be on the same axis as the valve stem when installed, and the eccentricity of the cap will interfere with other parts, resulting in obstruction of the valve stem movement and ultimately affecting the accuracy of water flow regulation.

[0016] The embodiments of the present utility model are further described below in conjunction with the accompanying drawings.
[0017] See also Figure 1 A cap structure for an instant hot water faucet specifically includes the following components: the cap 4 includes an adjustment mechanism 6 and a handle 5 fixed on the cap 4. An extension portion 1 is provided on one side of the cap 4, in which a water flow adjustment mechanism 62 and a rotationally adjustable valve stem 3 are installed. The valve stem 3 axially extends along the extension portion 1 and is connected to the axis of the cap 4. Two oppositely arranged first planes 3.1 and second planes 3.2 are provided at the end of the valve stem 3. A connecting portion 4.1 is provided at the axis of the cap 4, and the connecting portion 4.1 is plugged into the end of the valve stem 3, and the inner wall of the connecting portion 4.1 matches the end of the valve stem 3. Through this structure, a firm connection between the connecting portion 4.1 and the end of the valve stem 3 is ensured, and a good fit is provided. This enables the cap 4 and the valve stem 3 to rotate together to adjust the water flow.
[0018] Traditionally, the cap 4 is usually made of plastic or other materials that are easily deformed. However, when the handle 5 is installed, the cap 4 may be deformed due to the radial thrust applied by the threaded connection structure, resulting in the displacement of the axial position of the cap 4 from the axial position of the valve stem 3. To solve this problem, the structure is provided with an adjustment mechanism 6 on the cap 4 for adjusting the axial position of the cap 4 to ensure that the axial center of the cap 4 is consistent with the axial center of the valve stem 3. The specific adjustment mechanism 6 includes a fixing portion 6.1 and an adjustment portion 6.2. The fixing portion 6.1 extends to the outer edge of the cap 4 along the normal direction of the first plane 3.1, and a first threaded hole 6.1.1 is radially arranged on its upper portion. A threaded portion 5.1 is arranged on the connecting end of the handle 5, and the handle 5 is fixed to the fixing portion 6.1 by threading the threaded portion 5.1 with the first threaded hole 6.1.1. The adjustment portion 6.2 is a connecting portion 4.1 extending to the outer edge of the cap 4 along the normal direction of the second plane 3.2, and a second threaded hole 6.2.1 is radially arranged on its upper portion. An adjusting screw 6.3 is arranged in the second threaded hole 6.2.1, and the end of the adjusting screw 6.3 abuts against the second plane 3.2. By rotating the adjusting screw 6.3, one end of the adjusting screw 6.3 abuts against the second plane 3.2 of the valve stem 3, and the other end is threadedly connected with the second threaded hole 6.2.1, thereby changing the distance between the adjusting part 6.2 and the axis of the valve stem 3. The adjusting part 6.2 will drive the entire cap 4 to adjust the axis of the cap 4 to be consistent with the axis of the valve stem 3. This avoids the cap 4 from interfering with other parts due to the overall offset of the installation position, thereby affecting the regulating effect of the water flow.
[0019] The fixing part 6.1 and the adjusting part 6.2 are respectively provided with a detachable first connection block 6.1.2 and a second connection block 6.2.2. The connection blocks are respectively provided with a first threaded hole 6.1.1 and a second threaded hole 6.2.1. By installing the first threaded hole 6.1.1 and the second threaded hole 6.2.1 on the detachable connection block, when disassembly or replacement is required, it can be achieved by disassembling the connection block.
[0020] The end of the threaded portion 5.1 is indeed provided with a positioning portion 5.2, and a positioning hole 3.1.1 is also provided on the first plane 3.1. The positioning portion 5.2 is inserted into the positioning hole 3.1.1, and the outer wall of the positioning portion 5.2 matches the shape of the side wall of the positioning hole 3.1.1. This structure ensures that the handle 5 and the valve stem 3 are correctly positioned and fixed in the correct position.
