[0042] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0044] In the description of this utility model, "several" means more than one, "plurality" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of the terms "first" and "second" is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0045] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0046] In the description of the present invention, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the exemplary expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0047] Currently, all shower systems on the market are sold with a safety lock, which limits the outlet water temperature to around 38°C to 40°C to prevent burns caused by excessive temperatures. The shower system is equipped with a thermostat handle, and the safety lock is located on the handle. The safety lock consists of a button protruding from the handle and a locking structure located inside the handle. The user locks and unlocks the temperature by pressing the button.

[0048] However, there is a gap between the button and the outer shell of the temperature control handle. When the button is pressed, debris, moisture, etc. can easily enter the interior of the temperature control handle through the gap along with the button, thereby causing the temperature control handle to malfunction.

[0049] In order to solve the above problems, the first embodiment of the present application proposes a temperature control handle, such as Figures 1 to 6 As shown, the thermostat handle includes a fixed member 200, a rotating member 300, and a transmission member 400. It will be understood that the thermostat handle is used to connect to the valve core 100 on the thermostat body of the shower device. Specifically, one end of the valve core 100 is disposed in the water path of the shower device, and the other end is connected to the rotating member 300 via the transmission member 400. The rotation of the rotating member 300 drives the rotation of the valve core 100. The rotation of the valve core 100 can adjust the mixing ratio of hot and cold water, thereby adjusting the outlet water temperature of the shower device.

[0050] The fixing member 200 is a tubular structure, one end of which is used to connect with the thermostat body 600, and the other end of which is provided with a first abutting protrusion 210. The valve core 100 is provided through the fixing member 200. Figure 2 and Figure 3 As shown, the first abutting protrusion 210 includes an extension portion 211 and a protruding portion 212. The extension portion 211 extends along the axial direction of the rotating member 300, and the protruding portion 212 is provided at the end of the extension portion 211 and is located relatively outside the extension portion 211. It should be explained that the side closer to the rotation axis of the rotating member 300 is the relatively inner side, and the side farther from the rotation axis of the rotating member 300 is the relatively outer side.

[0051] The rotating member 300 is a tubular structure, wherein a rib 350 is provided in the middle thereof to separate the rotating member 300 into two chambers arranged in parallel along the axial direction. A first limiting groove 310 and a second limiting groove 320 are provided on the rib 350, and both the first limiting groove 310 and the second limiting groove 320 extend along the circumference of the rotating member 300. Figures 4 to 6 As shown, the wall surface of the rib 350 near the fixing member 200 is recessed to form a first limiting groove 310. The first limiting groove 310 is a semicircular annular groove. The second limiting groove 320 is provided through the rib 350 and is a quarter-circular through groove. It is understood that in other embodiments, the second limiting groove 320 can also have a groove structure similar to the first limiting groove 310. It should be noted that the lengths of the first limiting groove 310 and the second limiting groove 320 are determined according to the adjustment range of the valve core 100.

[0052] The rotating member 300 is mounted on the fixed member 200. The rotating member 300 is driven to rotate relative to the fixed member 200, or the rotating member 300 is driven to move relative to the fixed member 200. Specifically, the rotating member 300 has a first state and a second state. The first state is a temperature-limited state. The temperature adjustment range of the temperature adjustment handle is about 0 to 40°C. The water temperature within this range is suitable for most household use scenarios, and the water temperature is relatively safe and there is no risk of scalding. The second state is a temperature adjustment state. The temperature adjustment range of the temperature adjustment handle can be expanded to 0 to 60°C or other temperature ranges to adapt to a small number of scenarios that require the use of high-temperature hot water. It can be understood that the temperature adjustment ranges of the above-mentioned temperature adjustment handles are examples. In other embodiments, the temperature adjustment range in the first state can also be 0 to 38°C, and the temperature adjustment range in the second state can be 0 to 80°C, etc. The maximum temperature in the second state is greater than the maximum temperature in the first state.

[0053] Different from the prior art in which the first state and the second state are switched by pressing a button on the thermostat handle, in this embodiment, the state of the rotating member 300 is switched by pressing the rotating member 300 along its axial direction or by pulling the rotating member 300. Figure 5 and Figure 6 As shown in the example, Figure 5 Shown is a cross-sectional schematic diagram of the temperature control handle in the second state. Figure 6 This is a schematic diagram of the thermostat handle in its first state. To adjust the water temperature to above 40°C, press the rotating member 300 leftward, moving it axially toward the fixed member 200, thereby switching from the first state to the second state. Alternatively, to maintain the water temperature within the range of 0 to 40°C, pull the rotating member 300 rightward, moving it axially away from the fixed member 200, thereby switching from the second state to the first state.

[0054] It should be noted that, in the first state and the second state, if Figures 2 to 6 As shown, the rotating member 300 can rotate relative to the fixed member 200. In the first state, when the rotating member 300 rotates, the first abutting protrusion 210 can move in the first limiting groove 310. In the second state, the first abutting protrusion 210 can move in the first limiting groove 310 and the second limiting groove 320. It can be understood that, as shown in FIG. Figure 4 Taking the first limiting groove 310 and the second limiting groove 320 as an example, in the first state, the rotation range of the rotating member 300 is one-half of the circumference, while in the second state, the rotation range of the rotating member 300 is three-quarters of the circumference. Thus, the rotating member 300 has a larger rotation range in the second state, which drives the valve core 100 to have a larger rotation range, and thus, the temperature adjustment range of the temperature control handle in the second state is larger.

[0055] In order to facilitate the assembly connection between the rotating part 300 and the fixed part 200, the temperature control handle of the present application is also provided with a transmission part 400, which is respectively connected to the valve core 100 and the rotating part 300, so that the rotating part 300 can drive the valve core 100 to rotate through the transmission part 400.

[0056] Based on the above, it can be found that the temperature control handle of the present application can achieve temperature locking and unlocking. The water outlet temperature in the first state can meet most scenarios of daily use, and the hot water temperature is relatively safe. The water outlet temperature in the second state can be higher than the water outlet temperature in the first state, so as to meet some scenarios requiring high-temperature hot water. The temperature control handle switches between the first state and the second state by pressing or pulling the rotating member 300 in the axial direction. There is no need to set an additional protruding button on the outer shell of the temperature control handle (such as the rotating member 300, the decorative cover 360) to achieve the locking and unlocking functions. On the one hand, the appearance of the temperature control handle is smooth and more beautiful. On the other hand, there is no need to set an opening on the outer peripheral wall of the rotating member 300 to accommodate the button, so as to prevent debris, moisture, etc. from entering the interior of the temperature control handle through the outer peripheral wall of the rotating member 300 along with the button, thereby improving the working stability and service life of the temperature control handle.

[0057] In some embodiments, the transmission member 400 is engaged with the rotating member 300 and the valve core 100 for transmission. Figures 1 to 6 As shown, the transmission member 400 is provided with a first through hole 410 for the valve core 100 to pass through, and the outer peripheral wall and inner peripheral wall of the transmission member 400 (i.e., the hole wall of the first through hole 410) are both provided with a spline structure. Correspondingly, the valve core 100 and the rotating member 300 are also provided with a spline structure. For the convenience of distinction, the spline structure on the outer peripheral wall of the transmission member 400 is named the first spline, and the spline structure on the hole wall of the first through hole 410 is named the second spline. The outer peripheral wall of the valve core 100 is provided with a third spline, and the rotating member 300 is provided with a second through hole 341 for the transmission member 400 to pass through, and the hole wall of the second through hole 341 is provided with a fourth spline. The transmission member 400 is sleeved on the valve core 100, and the second spline and the third spline are engaged, so that the transmission member 400 and the valve core 100 are engaged and transmitted. The transmission member 400 is inserted into the second through hole 341 of the rotating member 300, and the first spline and the fourth spline are engaged, so that the transmission member 400 and the rotating member 300 are engaged and transmitted. Then, when the rotating member 300 rotates, the transmission member 400 and the valve core 100 are driven in sequence.

[0058] In some embodiments, the number of teeth of the inner and outer spline structures of the transmission member 400 is the same. According to the above structure, the assembly process of the temperature control handle is as follows:

[0059] Step 1: Adjust the valve core 100 to 40°. During the subsequent assembly process, the valve core 100 must remain in this state and cannot rotate, otherwise it will be considered as a deviation.

[0060] Step 2: The fixing member 200 is sleeved on the valve core 100 and connected to the temperature regulating body 600 so that the positions of the fixing member 200 and the valve core 100 are relatively determined.

[0061] Step 3: The rotating member 300 is sleeved on the fixing member 200, and the first abutting protrusion 210 of the rotating member 300 is inserted into the first limiting groove 310, and rotated to the maximum temperature position of the first limiting groove 310, that is, Figure 4 The position shown is in contact with the first limiting flange 330. In the subsequent assembly process, the rotating member 300 must be kept in this state and cannot rotate, otherwise it is considered to be a deviation.

[0062] Step 4: Insert the transmission member 400 into the gap between the valve core 100 and the rotating member 300, and engage with the valve core 100 and the rotating member 300 for transmission respectively, and the assembly is completed.

[0063] It should be noted that, because it is necessary to precisely ensure that when the valve core 100 is adjusted to 40°C, the rotating member 300 is exactly located at the maximum temperature position of the first limiting groove 310, and due to the influence of the dimensional error of the valve core 100, the processing error of the first limiting groove 310, and the assembly error of various accessories, in the actual assembly process, in step 4, the spline structure on the valve core 100 and the spline structure on the rotating member 300 are often not aligned one by one, resulting in the transmission member 400 being unable to be inserted between the valve core 100 and the rotating member 300. If either the valve core 100 or the rotating member 300 is rotated to align the splines, the adjusted temperature of the valve core 100 and the maximum temperature of the first limiting groove 310 will not accurately correspond.

[0064] To solve the above problem, in a further embodiment, the number of teeth of the first spline is set to be greater than the number of teeth of the second spline, the number of teeth of the fourth spline is the same as the number of teeth of the first spline, and the number of teeth of the third spline is the same as the number of teeth of the second spline. Taking the second spline with 32 teeth and the first spline with 33 teeth as an example, correspondingly, the third spline has 32 teeth and the fourth spline has 33 teeth. The spacing angle of each tooth of the second spline is 11.25°, and the spacing angle of each tooth of the first spline is 10.91°, with a difference of 0.34° per tooth. During assembly, to ensure that the second spline is centered and adapted, the angle adaptation deviation of the first spline is 5.5°, so that the spline cannot be inserted. Furthermore, after the transmission part 400 is rotated 16 teeth relative to the valve core 100 and then adapted, its angular deviation is eliminated by 5.44°, and the final angular deviation is 0.06°. This deviation is small, and the spline can be smoothly inserted between the valve core 100 and the rotating part 300, while ensuring that the respective positions of the valve core 100 and the rotating part 300 do not change.

[0065] In some embodiments, as Figures 4 to 6As shown, one end of the first limiting groove 310 is provided with a first limiting surface 311, and the other end is connected to the second limiting groove 320. The first limiting surface 311 can be defined by a protrusion provided in the first limiting groove 310, or can be formed by the end wall of the first limiting groove 310. The second limiting groove 320 is provided with a first limiting flange 330. The first limiting flange 330 is located at the opening of the second limiting groove 320 and extends from one side of the groove wall of the second limiting groove 320. The first limiting flange 330 is spaced from the other side of the groove wall, leaving a gap to facilitate the extension portion 211 of the first abutting protrusion 210 to pass through in the second state.

[0066] When the first abutting protrusion 210 moves in the first limiting groove 310, it can respectively abut against the first limiting surface 311 and the end wall of the first limiting flange 330, thereby limiting the rotation range of the rotating member 300 in the first state. Figure 4 The first end wall 331 shown. It is understood that Figure 3 and Figure 4 As shown, the extension portion 211 and the protrusion 212 of the first abutting protrusion 210 can abut against the first limiting surface 311 to limit the lowest adjustment temperature of the temperature control handle in the first state, and then the rotating member 300 can move along the Figure 4 The counterclockwise rotation as shown causes the protruding portion 212 of the first abutting protrusion 210 to abut against the first end wall 331 , thereby defining the maximum adjustment temperature of the temperature adjustment handle in the first state.

[0067] Furthermore, when the adapter is driven to move along the axial direction of the rotating member 300, the protrusion 212 and the end wall of the first limiting flange 330 gradually intersect, and the first end wall 331 no longer abuts against the protrusion 212. At this time, the first abutting protrusion 210 can avoid the first limiting flange 330 from entering the second limiting groove 320. Figures 4 to 6 As shown, a second limiting surface 321 is provided at one end of the second limiting groove 320 away from the first limiting groove 310. When the first abutting protrusion 210 moves in the first limiting groove 310 and the second limiting groove 320, it can abut against the first limiting surface 311 and the second limiting surface 321 respectively to limit the rotation range of the rotating member 300 in the second state.

[0068] Furthermore, the rotating member 300 further includes a connecting portion 340, such as Figures 3 to 6As shown, the connecting portion 340 is protruded on the rib plate 350 and is an annular thin-walled structure, which defines a second through hole 341 for the transmission member 400 to pass through. The outer peripheral wall of the connecting portion 340 is protruded with a second limiting flange 342, and the second limiting flange 342 is defined by a notch 343. The inner peripheral wall of the fixing member 200 is protruded with a second abutting protrusion 220. When the rotating member 300 switches from the first state to the second state, the second abutting protrusion 220 passes through the notch 343, and the first abutting protrusion 210 is staggered with the first end wall 331, so that the first abutting protrusion 210 can enter the second limiting groove 320. It can be understood that the side wall of the second limiting flange 342 refers to Figure 5 The first side wall 345 is shown.

[0069] It should be noted that the temperature control handle also includes an elastic member 500, such as Figure 5 As shown, after the temperature control handle is installed on the shower device, one end of the elastic member 500 abuts against a component on the temperature control body 600, and the other end is connected to the rotating member 300. When the rotating member 300 switches from the first state to the second state, the elastic member 500 is compressed, thereby having a tendency to return from the second state to the first state. When the rotating member 300 rotates until the second abutting protrusion 220 aligns with the notch 343, the elastic member 500 drives the rotating member 300 to move away from the fixed member 200, switching the temperature control handle back to the first state, thereby improving the safety of the shower device.

[0070] It should be understood that, due to the arrangement of the elastic member 500, the rotating member 300 is subjected to an elastic force in the direction away from the fixed member 200 in the second state, and the rotating member 300 and the fixed member 200 are in contact with each other through the second contact protrusion 220 and the second limiting flange 342. There are multiple second contact protrusions 220, which are evenly distributed along the circumference of the inner peripheral wall of the fixed member 200. For example, Figure 3 and Figure 5 In the illustrated embodiment, two second abutting protrusions 220 are provided, and correspondingly, two notches 343 are provided on the second position-limiting flange 342. After the second abutting protrusions 220 pass through the notches 343 and, under the action of the elastic member 500, abut against the first sidewall 345 of the second position-limiting flange 342, the two second abutting protrusions 220 can evenly distribute the axial abutting force between the fixed member 200 and the rotating member 300, replacing the first abutting protrusion 210 in abutting contact with the first position-limiting flange 330, thereby preventing the rotating member 300 from being stuck due to eccentric force.

[0071] It is understandable that if Figure 5 and Figure 6As shown, when the first abutting protrusion 210 abuts the first end wall 331 of the first limiting flange 330, the second abutting protrusion 220 is arranged corresponding to the notch 343. Thus, the rotating member 300 is displaced in the axial direction after being compressed, so that the first abutting protrusion 210 and the first end wall 331 are staggered, and at the same time, the second abutting protrusion 220 is also arranged through the notch 343. The rotating member 300 then rotates so that the first abutting protrusion 210 enters the second limiting groove 320, or rotates in the opposite direction to return to the first limiting groove 310. At the same time, the second abutting protrusion 220 abuts and slides against the first side wall 345 of the second limiting flange 342.
