[0002] At present, thermostatic faucets on the market are all sold with an indicated temperature (usually 38°C or 40°C). However, due to the easy assembly error caused by conventional structures, the water outlet temperature will have a large deviation during mass production. At the same time, most companies and industry standards require that the actual water outlet temperature should not deviate from the indicated temperature by more than ±2°C. In order to ensure accurate water outlet temperature, it is often necessary to spend a high price on assembly inspection, rework, and actual detection and calibration of the water outlet temperature of the faucet after assembly. Obviously, the production efficiency of such solutions is relatively low. Utility Model Content

[0028] At present, the constant-temperature water outlet devices on the market are all sold with a marked temperature (usually 38°C or 40°C). That is, when the constant-temperature valve core rotates to the marked temperature position, the constant-temperature water outlet device discharges water at the marked temperature. The marked temperature position is the position where the constant-temperature valve core is located when the constant-temperature water outlet device discharges water at the marked temperature. However, users cannot observe the position of the constant-temperature valve core. For the convenience of users to observe, it is usually achieved by aligning the temperature adjustment handle with the water outlet main body. A specific example is to mark the first marked temperature position on the handle and mark the second marked temperature position on the surface of the water outlet main body. When the constant-temperature valve core rotates to the marked temperature position, the water outlet temperature at this time is the marked temperature of the water outlet device, and the first marked temperature position on the handle is aligned with the second marked temperature position on the water outlet main body. Since the temperature adjustment handle and the constant-temperature valve core rotate synchronously, users can thus judge whether the constant-temperature valve core has rotated to the marked temperature position by whether the first marked temperature position and the second marked temperature position are aligned. However, this is an ideal situation. In reality, the current installation process is to first adjust the constant-temperature valve core to the marked temperature position, and then assemble the temperature adjustment handle as a whole onto the main body of the water outlet device. Specifically, the temperature adjustment handle is inserted into the constant-temperature valve core. There are splines in the temperature adjustment handle. When the temperature adjustment handle is rotated, the constant-temperature valve core will also rotate accordingly to achieve temperature adjustment. When the temperature adjustment handle is inserted into the constant-temperature valve core, the ideal state is that the first marked temperature position on the temperature adjustment handle exactly aligns with the second marked temperature position on the water outlet main body to meet the condition that the first marked temperature position aligns with the second marked temperature position = the constant-temperature valve core is at the marked temperature position. However, since workers cannot observe the inside of the temperature adjustment handle during the assembly process, that is, the temperature adjustment handle is blindly installed when it is sleeved onto the constant-temperature valve core, it is more common that the first marked temperature position on the temperature adjustment handle does not align with the second marked temperature position on the water outlet main body after the temperature adjustment handle is assembled onto the main body. When they are not aligned, workers will rotate the temperature adjustment handle to make the first marked temperature position align with the second marked temperature position. However, during the rotation of the temperature adjustment handle, the constant-temperature valve core also rotates accordingly. Since the position of the constant-temperature valve core has rotated, even if the first marked temperature position aligns with the second marked temperature position at this time, the water outlet temperature at this time is no longer the above-mentioned marked temperature, and there is a deviation between the actual water outlet temperature and the above-mentioned marked temperature. From the user's perspective, there is a problem that rotating the temperature adjustment handle to a specific position cannot make the water outlet device discharge water at the preset temperature. Therefore, in the prior art, due to the existence of the above problems, to ensure that the relationship between the water outlet temperature and the rotation position meets the preset standard, after the temperature adjustment handle is assembled onto the main body, it is necessary to add a detection process for the water outlet temperature to test whether the water outlet device discharges water at the preset temperature when the temperature adjustment handle rotates to a specific position, which increases the production cost, has low efficiency, and has a high error rate and reinstallation rate.
[0029] And an embodiment of the present application provides a water outlet device. Refer toFigure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the water outlet device includes a water outlet body 1 and a temperature control handle 2, the water outlet body 1 includes a thermostatic valve core 11, the thermostatic handle 2 is installed on the water outlet body 1 and can rotate relative to the water outlet body 1, the thermostatic handle 2 includes a handle body 3, an adapter 4 and a fastener 5, a mounting portion is provided in the handle body 3, the mounting portion includes a mounting hole 34, the center of the mounting hole 34 coincides with the center of the handle body 3, the adapter includes an adapter body 41, the adapter 4 can be detachably installed on the mounting portion, and its adapter body 41 passes through the mounting hole and is sleeved on the thermostatic valve core 11, the adapter body 41 is transmission-connected with the thermostatic valve core 11, so that when the thermostatic handle 2 is rotated, the thermostatic valve core 11 rotates accordingly, the fastener is used to connect the thermostatic handle 2 and the thermostatic valve core 11, the surface of the handle body 3 is provided with a first explicit temperature position mark, and the surface of the water outlet body 1 is provided with a second explicit temperature position mark.
[0030] The installation steps of the water outlet device of this embodiment are as follows:
[0031] S1: Adjust the thermostatic valve core to the indicated temperature position, i.e., the position where the water outlet device flows out water of the indicated temperature;
[0032] S2: Sleeve the handle body 3 onto the water outlet body 1, and rotate the handle body 3 so that the first temperature position mark on the surface of the handle body 3 is aligned with the second temperature position mark on the surface of the water outlet body 1;
[0033] S3: Using the mounting portion of the handle body 3 to mount the adapter 4 on the handle body 3, and to achieve transmission connection with the thermostatic valve core 11, that is, to mount the adapter 4 on the mounting portion and to make the adapter body 41 pass through the mounting hole 34 and be sleeved on the thermostatic valve core 11, so as to achieve transmission connection with the thermostatic valve core 11;
[0034] S4: Use fasteners to connect and fix the temperature control handle 2 and the thermostatic valve core 11.
[0035] It can be understood that the adapter connected to the thermostatic valve core in this embodiment is sleeved on the thermostatic valve core after step S2. In step S2, the handle body 3 is sleeved on the water outlet body 1, and the handle body 3 itself is not connected to the thermostatic valve core 11 in a driving manner. Therefore, in this step, no matter how the handle body 3 is rotated, the thermostatic valve core 11 will not rotate, and the thermostatic valve core 11 still remains at the marked temperature position. Then, steps S3 and S4 are carried out to enable the temperature adjustment handle 2 to be connected to the thermostatic valve core 11 in a driving manner and locked and fixed. After being locked and fixed, the alignment of the first marked temperature position on the handle body 3 adjusted in step S2 with the second marked temperature position on the surface of the water outlet body 1 means that the thermostatic valve core 11 is at the marked temperature position. Since the thermostatic valve core 11 is not rotated and deviated from its original position during the entire assembly process, that is, the thermostatic valve core 11 has always been at the marked temperature position, the problem that in the current technology, the worker rotates the handle to align during the assembly process, causing the thermostatic valve core to rotate together, and the user rotates the temperature adjustment handle to a specific position but cannot obtain water at the preset temperature is avoided.
[0036] It can be understood that the first and second marked temperature position identifiers can be marking lines or marking points or any other marks that can be observed by the user.
[0037] In some embodiments, the installation part further includes a first positioning part, and the adapter 4 is provided with a second positioning part, and the first positioning part cooperates with the first positioning part to position and install the adapter on the installation part.
[0038] During the process of sleeving the adapter 4 on the thermostatic valve core 11, the second positioning part is installed on the first positioning part of the handle body to position the whole adapter on the installation part.
[0039] Reference Figure 4 , in some embodiments, the first positioning part includes a first positioning groove 32 and a second positioning groove 33 symmetrically arranged on both sides of the installation hole 34, and the second positioning part includes a first positioning convex block 42 and a second positioning convex block 43 symmetrically arranged on both sides of the adapter main body 41. The first positioning convex block 42 is arranged in the first positioning groove 32, and the second positioning convex block 43 is arranged in the second positioning groove 33.
[0040] Reference Figure 4 and Figure 5 , in some embodiments, the height relationship between the second positioning convex block 43 and the adapter main body 41 satisfies that during the process of sleeving the adapter 4 on the thermostatic valve core 11, when the bottom end of the second positioning convex block 43 is flush with the top end of the second positioning groove 33, the adapter main body 41 is not sleeved on the thermostatic valve core 11, and when the second positioning convex block 43 is installed in place in the second positioning groove 33, the adapter main body 41 is sleeved on the thermostatic valve core 11 in place.
[0041] In this embodiment, by designing the height of the second positioning bump 43, during the process of sleeving the adapter on the thermostatic valve element 11, the second positioning bump 43 and the second positioning groove 33 are first in positioning cooperation, and then the adapter body gradually enters the process of sleeving on the thermostatic valve element 11, reducing the assembly difficulty. Wherein, the second positioning bump being installed in place in the second positioning groove means that the second positioning bump cannot be further pushed into the second positioning groove.
[0042] Reference Figure 6 , in some embodiments, in the axial direction of the temperature adjustment handle 2, along the direction away from the thermostatic valve element 11, the gap between the second positioning bump 43 and the groove wall of the second positioning groove 33 gradually becomes smaller until the second positioning bump 43 is completely attached to the groove wall of the second positioning groove 33.
[0043] In this embodiment, in the axial direction of the temperature adjustment handle 2 and in the direction away from the thermostatic valve element 11, the gap between the second positioning bump 43 and the groove wall of the second positioning groove 33 gradually becomes smaller until it is completely attached. In this way, during the assembly process, when the second positioning bump 43 is gradually inserted into the second positioning groove 33, in the previous section, since there is a gap between the second positioning bump 43 and the groove wall of the second positioning groove 33, there is a certain adjustment space when the adapter body and the thermostatic valve element start to be sleeved. Therefore, it can better ensure that the adapter body 41 is in transmission connection with the thermostatic valve element 11, and the gap gradually becomes smaller until it is completely attached. Therefore, after the second positioning bump 43 is completely inserted into the second positioning groove 33, the gap has been eliminated, the second positioning bump 43 cannot shake relative to the second positioning groove 33, and the adapter body cannot shake relative to the thermostatic valve element 11 either.
[0044] In some embodiments, the height relationship between the first positioning bump 42 and the adapter body 41 satisfies that during the process of sleeving the adapter on the thermostatic valve element 11, when the bottom end of the first positioning bump 42 is flush with the top end of the first positioning groove 32, the adapter body 41 is not sleeved on the thermostatic valve element 11, and when the first positioning bump 42 is installed in place in the first positioning groove, the adapter body 41 is sleeved on the thermostatic valve element 11 in place.
[0045] In some embodiments, in the axial direction of the temperature adjustment handle 2, along the direction away from the thermostatic valve element 11, the gap between the first positioning bump 42 and the groove wall of the first positioning groove 32 gradually becomes smaller until the first positioning bump 43 is completely attached to the groove wall of the first positioning groove 32.
[0046] In some embodiments, the thermostatic valve element 11 is in spline connection with the adapter body 41.
[0047] Such asFigure 2 As shown, in this embodiment, the adapter body 41 passes through the mounting hole 34 and is sleeved on the thermostatic valve core 11. A spline 44 is provided on the inner surface of the adapter body 41, and a spline is also provided on the thermostatic valve core 11. The adapter body 41 is sleeved on the thermostatic valve core 11, and the splines of the two are in mating connection.
[0048] In some embodiments, the maximum clearance width between the second positioning convex block 43 and the groove wall of the second positioning groove 33 is the displacement corresponding to a 1 / 2 tooth rotation angle of the spline of the thermostatic valve core 11.
[0049] In some embodiments, the maximum clearance width between the first positioning convex block 42 and the groove wall of the first positioning groove 32 is the displacement corresponding to a 1 / 2 tooth rotation angle of the spline of the thermostatic valve core 11.
[0050] In some embodiments, the thermostatic valve core 11 is connected to the adapter body 41 by a flat key.
[0051] As Figure 2 shown, in some embodiments, the fastener is a screw 5. The screw 5 passes through the adapter body 41 and connects the temperature adjustment handle 2 and the thermostatic valve core 11.
[0052] As Figure 2 shown, in some embodiments, the water outlet device further includes a temperature limit part 12. A limit part 31 is provided in the handle body 3. When the temperature adjustment handle is rotated to drive the thermostatic valve core to rotate to the indicated temperature position, the limit part 31 abuts against the temperature limit part 12.
[0053] In this embodiment, the temperature limit part 12 is provided on the water outlet device, and the limit part 31 is provided in the handle body. When the temperature adjustment handle 2 is rotated to drive the thermostatic valve core 11 to rotate to the indicated temperature position, the limit part 31 abuts against the temperature limit part 12. Thus, the temperature limit part 12 can give a resistance to the continued rotation of the handle. On the one hand, it can enable the user to more clearly perceive that the thermostatic valve core 11 has rotated to this position because of the resistance. On the other hand, it can prevent the user from rotating excessively and being scalded.
[0054] As Figure 2 shown, in some embodiments, the temperature adjustment handle further includes a decorative cover 6. The decorative cover 6 covers the top of the handle body 3.
[0055] The above are only optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
