[0032] The embodiments of the present invention are described in detail below, and 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 to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] In an embodiment of the first aspect of the utility model, a temperature limiting ring 100 is provided, which can be applied to a water outlet device 1000 such as a faucet and a shower that needs to adjust the water temperature. When a handle, a hand wheel 300, etc. rotates the temperature control component to drive the valve core to adjust the water outlet temperature, it can cooperate with the positioning parts on the temperature control component, such as a positioning pin 240, a positioning rod, etc., to limit the rotation angle of the temperature control component, thereby preventing the user from accidentally adjusting the temperature too high and causing burns.

[0034] refer to Figure 1 and Figure 2 According to the temperature limiting ring 100 of the embodiment of the utility model, in order to adapt to the rotation path of the handle, the temperature limiting ring 100 can be set to a circular ring shape, and a plurality of stoppers are arranged in sequence in the circumferential direction of one side thereof, including at least a first stopper 111, a second stopper 112 and a third stopper 113, wherein the first stopper 111 and the second stopper 112 are connected by a first guide surface 114, and the second stopper 112 and the third stopper 113 are connected by a second guide surface 115.

[0035] It can be understood that the first stopper 111, the second stopper 112 and the third stopper 113 are all oriented in the same direction and toward the circumferential direction of the temperature limiting ring 100. When the handle is rotated along its circumference, the positioning member can be stopped. Furthermore, the radial length of the third stopper 113 along the temperature limiting ring 100 is greater than the radial thickness of the first stopper 111 and the second stopper 112 along the temperature limiting ring 100. When the user needs to change the stopper to be stopped, the positioning member needs to be pressed and adjusted to a different position. For example, the positioning member needs to be pressed to disengage from the first stopper 111 before it can continue to move toward the second stopper 112 and the third stopper 113.

[0036] The temperature limiting ring 100 is also provided with a limit block 120, which is arranged between the first stop 111 and the second stop 112, and a passage 116 is formed between the limit block 120 and the first guide surface 114, wherein in the radial direction of the temperature limiting ring 100, the width of the passage 116 is less than or equal to the width of the second stop 112. Figure 1 and Figure 2The limit block 120 is arranged on the side of the first guide surface 114 close to the center of the temperature limiting ring 100, which blocks the path of the positioning member directly rotating to the third stop table 113 after it leaves the position of the first stop table 111. Therefore, the positioning component must stop on the side of the limit block 120 close to the first stop table 111, and first turn to the second stop table 112 through the aisle 116. Since the width of the aisle 116 is less than or equal to the width of the second stop table 112 in the radial direction of the temperature limiting ring 100, the positioning member cannot move directly to the third stop table 113 after passing through the aisle 116, but will be stopped by the second stop table 112. Therefore, it can avoid the user being unable to accurately control the position of the positioning component and mistakenly adjusting the positioning member directly to the third stop table 113, thereby causing the water outlet temperature to be too high and causing scalding and other problems.

[0037] It is understandable that the temperature limiting ring 100 may be provided with a fourth stopper, a fifth stopper, and other multiple stoppers, and the adjacent stoppers are connected by different guide surfaces, so that the user can choose more stop positions and provide more diverse water outlet temperatures. At the same time, multiple limit blocks 120 may also be provided, which are arranged in front of different guide surfaces to prevent misoperation of the positioning component, ensure the appropriate water outlet temperature and the safety of the user.

[0038] It can be understood that the limit block 120 is not limited to being set between the first stop table 111 and the second stop table 112. When the number of stop tables is greater than three, it can be set between any two stop tables and form an aisle with the guide surface between the two stop tables to limit the positioning member from rotating directly to a stop table position with a higher temperature due to misoperation.

[0039] It should be pointed out that the first stopper 111 is not limited to being the first stopper on the rotation path of the positioning member, but can be the second, the third or any one of them. As long as any three adjacent stoppers are provided, they can be defined as the first stopper 111, the second stopper 112 and the third stopper 113 respectively.

[0040] refer to Figure 1 and Figure 2 In some embodiments of the present invention, an arcuate convex rib 110 is provided on the side of the temperature limiting ring 100, and the arcuate convex rib 110 is provided along the circumference of the temperature limiting ring 100, and the plurality of anti-rotation platforms, the first guide surface 114 and the second guide surface 115 are all provided on the arcuate convex rib 110. That is, the arcuate convex rib 110 is protruding compared to the side of the temperature limiting ring 100, wherein the plurality of side walls facing along the circumference of the temperature limiting ring 100 are the plurality of anti-rotation platforms, and the plurality of side walls facing along the center of the temperature limiting ring 100 are the guide surfaces, which connect the adjacent anti-rotation platforms.

[0041] refer to Figure 1 and Figure 2In some embodiments of the present invention, a guide slope 121 is provided on one side of the limit block 120 close to the second stop table 112, and the guide slope 121 faces the second stop table 112, so that the positioning member can be guided when it is reset from the third stop table 113 to the first stop table 111.

[0042] refer to Figure 1 and Figure 2 In some embodiments of the present invention, at least one guide surface on the temperature limiting ring 100 is provided with a tooth surface, so that when the positioning member moves on the above-mentioned guide surface, it can cooperate with the tooth surface to cause a sense of stagnation and a sound of stagnation on the positioning component, which is used to remind the user of a certain water outlet temperature range. For example, a tooth surface can be provided on the guide surface of the area corresponding to the high-temperature water outlet. When the user adjusts to this temperature, the sense of stagnation and the sound of stagnation can remind the user that the water outlet is currently in a high-temperature state, thereby preventing the user from being scalded by hot water without knowing it.

[0043] It is understandable that the tooth surface can also be arranged on the side of the temperature limiting ring 100 in the high temperature area, and can also cooperate with the positioning piece to cause a sticking feeling and a sticking sound.

[0044] refer to Figure 3 , Figure 4 and Figure 5 In an embodiment of the second aspect of the utility model, a handle module is provided, comprising the temperature limiting ring 100 described in the above embodiment, and a temperature regulating component for connecting to the valve core, the temperature regulating component can control the movement of the regulating rod 400 in the valve core to adjust the ratio of cold and hot water, and then adjust the temperature of the mixed water outlet. The temperature regulating component is provided with a positioning member that can rotate with the rotation of the temperature regulating component, such as a positioning pin 240, and the positioning pin 240 can slide back and forth along the radial direction of the temperature limiting ring 100, so as to disengage from or stop on different stop tables. For example, when the displacement of the positioning pin 240 along the radial direction of the temperature limiting ring 100 is greater than the length of the first stop table 111, it can be disengaged from the first stop table 111 and rotate with the rotation of the temperature limiting component, and when the positioning pin 240 is subsequently rotated along the first guide surface 114 to the second stop table 112, it can stop on the second stop table 112, at which time, the valve core rotates to the corresponding water outlet temperature position to achieve the preset target temperature water outlet.

[0045] When the positioning pin 240 stops at the second stop 112, the user can drive the positioning pin 240 to slide to disengage from the second stop 112, and then continue to slide toward the third stop 113 and stop, so as to achieve higher water temperature. When the user wants to rotate the positioning pin 240 from the first stop 111 to the second stop 112, the positioning pin 240 will be driven to slide radially along the temperature limit ring 100. At this time, since the positioning pin 240 is located inside the handle module, the user cannot accurately determine the radial position of the positioning pin 240 on the temperature limit ring 100, so it is often easy to drive the positioning pin 240 too far, so that when the temperature control component rotates, it cannot stop on the second stop 112, but directly crosses the second stop 112 and rotates directly to the third stop 113, resulting in the water outlet temperature being higher than the target water outlet temperature. By setting the limit block 120 on the temperature limiting ring 100, the rotation path of the positioning pin 240 caused by the above-mentioned misoperation can be limited, so that the positioning pin 240 must stop on the limit block 120. The positioning pin 240 needs to move to the aisle 116 and stop at the second stop table 112 first, so that the water outlet temperature control is more accurate and safe.

[0046] refer to Figure 3 , Figure 4 and Figure 5 In some embodiments of the present invention, the temperature control component includes a slide groove 250 and a pressing component. The slide groove 250 extends along the radial direction of the temperature limiting ring 100. The positioning pin 240 is slidably set in the slide groove 250. The pressing component is connected to the positioning pin 240 to drive the positioning pin 240 to slide in the slide groove 250, thereby changing the radial position of the positioning pin 240 in the temperature limiting ring 100, so that it can rotate with the temperature control component and stop on different stop tables.

[0047] refer to Figure 5 In some embodiments of the utility model, an elastic clip 251 is provided in the slide 250, and the length of the slide 250 above the elastic clip 251 is L, wherein L is equal to the length of the first stop 111 along the radial direction of the temperature limiting ring 100, and the opening width of the elastic clip 251 is smaller than the diameter of the positioning pin 240. Therefore, when the positioning pin 240 is driven by the pressing component and slides along the slide 250, when it needs to be separated from the first stop 111, the positioning pin 240 needs to squeeze the elastic clip 251 to deform it before it can pass, that is, it needs to overcome the resistance of the elastic clip 251 before it can continue to slide. At this time, resistance and a sense of stuck are provided to the user to prompt the user that the user has successfully separated from the first stop 111. When the user receives the resistance feedback, the positioning pin 240 can be stopped from sliding and the temperature regulating component can be rotated. This can avoid the user being unable to accurately judge the position of the positioning pin 240 and directly pressing the positioning pin 240 to a deeper position, and directly rotating it to the stop with a high water outlet temperature when rotating.

[0048] Furthermore, a plurality of elastic clips may be provided in the slide groove 250, wherein the length of the slide groove 250 above each elastic clip corresponds to the length of a stop table, so that the user can obtain feedback at a plurality of adjustment positions, thereby achieving accurate temperature adjustment.

[0049] refer to Figure 3 , Figure 4 and Figure 5 In some embodiments of the present invention, the pressing assembly includes a button 230 and a spring 220, and the temperature adjustment assembly includes a bushing 200 and a hand wheel 300. The bushing 200 and the hand wheel 300 are fixedly connected. When the user drives the hand wheel 300 to rotate, the bushing 200 also rotates accordingly. The bushing 200 is provided with a slide groove 250 and a button groove 210, and the hand wheel 300 is provided with a through hole 310. The spring 220 and the button 230 are sequentially arranged in the button groove 210, and the end of the button 230 facing away from the spring 220 passes through the through hole 310 and is exposed. Therefore, the user can drive the positioning pin 240 to slide in the slide groove 250 by pressing the button 230.

[0050] In some embodiments of the present invention, a pin hole 231 is provided on the button 230 , and the positioning pin 240 is passed through the pin hole 231 . When the button 230 is pressed and driven, the positioning pin 240 slides accordingly.

[0051] refer to Figure 6 In an embodiment of the third aspect of the utility model, a water outlet device 1000 is also provided, including a temperature limiting ring 100 or a handle module as provided in the above embodiment, and also including a valve core, the valve core including a valve body (not shown) and an adjusting rod 400, the valve core is installed in the water outlet device 1000, the temperature limiting ring 100 is fixedly connected to the valve body, the handle module is fixedly connected to the adjusting rod 400, when the handle module rotates, the adjusting rod 400 rotates accordingly to control the valve core to adjust the water outlet temperature.
