Description

Technical Field

[0001] This utility model relates to the field of bathroom technology, and in particular to a thermostatic shower. Background Technology

[0002] Thermostatic valve cores are widely used in showers. They regulate the ratio of hot and cold water through temperature sensing elements to maintain a stable water temperature and are a core component for ensuring safe and comfortable water use.

[0003] However, in environments with poor water quality (such as hard water or high concentration of impurity ions), the thermostatic valve core is prone to scale formation due to the precipitation of calcium and magnesium ions after long-term use. Scale can clog the internal flow channels, leading to a decrease in water flow, delayed temperature control response, and even causing the thermostatic valve core to lose its thermostatic function, requiring timely cleaning.

[0004] The existing cleaning of thermostatic valve cores requires professional operation. The process involves using special tools to remove the handwheel, disassemble the valve core, descale, and then reinstall it. This process is time-consuming and costly. Furthermore, the reinstallation process requires repeated adjustments to the installation angle of the handwheel and the valve stem of the thermostatic valve core, making the operation cumbersome.

[0005] In view of the above, the designer of this utility model designed this utility model. Utility Model Content

[0028] Reference Figures 1 to 7 As shown, this utility model discloses a thermostatic shower, including: a shower body 1, a valve body 2, a thermostatic valve core 3, and a handwheel 4. The thermostatic valve core 3 is installed inside the valve body 2, and the handwheel 4 is fixedly installed to the valve stem of the thermostatic valve core 3. The valve body 2 is installed inside the shower body 1, and the handwheel 4 is installed on the outside of the shower body 1. The valve body 2 and the thermostatic valve core 3 are fixed together by a fixing member 5. The outer wall of the fixing member 5 is provided with an operating part, which is located outside the shower body 1. By operating the operating part, the fixing between the valve body 2 and the thermostatic valve core 3 can be selectively released or completed.

[0029] Therefore, the valve body 2 and the thermostatic valve core 3 of this utility model are fixed together by a fixing member 5. The outer wall of the fixing member 5 is provided with an operating part, which is located outside the shower body 1. When it is necessary to clean or repair the thermostatic valve core 3, please refer to [the relevant documentation]. Figures 2 to 5 As shown, the fixing between the valve body 2 and the thermostatic valve core 3 can be released simply by operating the external operating unit, and then the thermostatic valve core 3 can be easily removed; after maintenance or cleaning, it can be fixed again by operating the unit, achieving quick and convenient installation; the whole process does not require any additional special tools, which simplifies the disassembly and assembly steps, reduces the intensity of disassembly and assembly, and allows users to complete the disassembly and assembly independently, greatly improving the efficiency of cleaning, maintenance and installation of the thermostatic valve core 3.

[0030] The shower body 1 and the valve body 2 are detachably fixed together. Specifically, the shower body 1 and the valve body 2 are locked together by multiple self-tapping screws.

[0031] In the embodiment shown in the figure, the operating part of the fixing member 5 is a knob, so that the user can release the fixing between the valve body 2 and the thermostatic valve core 3 by rotating the knob; please refer to Figure 3 The knob can be turned out by hand, and then the handwheel 4 can be removed together with the thermostatic valve core 3 for maintenance and cleaning.

[0032] The fixing member 5 can be fixed to the thermostatic valve core 3 by means of threads or interference fit.

[0033] In the embodiment shown in the figure, the fixing member 5 is fixed to the thermostatic valve core 3 by means of threads. The fixing member 5 has a screw 53 in the middle. The shower body 1 has a first through hole 12, the valve body 2 has a second through hole 22, and the thermostatic valve core 3 has a screw hole 31. The screw 53 of the fixing member 5 passes through the first through hole 12 and the second through hole 22, and is screwed into the screw hole 31. The diameter of the first through hole 12 is larger than the diameter of the second through hole 22; thereby making the screw 53 screw... The thread passes through the shower body 1, locking the valve body 2 and the thermostatic valve core 3. The valve body 2 can be made of a material that is less prone to deformation than the shower body 1, such as copper for the valve body 2 and plastic for the shower body 1. The copper valve body 2 has higher structural strength, while the plastic shower body 1 has lower strength. The diameter of the second through hole 22 of the valve body 2 is smaller than the diameter of the first through hole 12 of the shower body 1, making the valve body 2 the main load-bearing component. The thermostatic valve core 3 is fixed by the cooperation of the screw 53 with the second through hole 22 and the screw hole 31.

[0034] Furthermore, for ease of installation, the handwheel 4 and the adjusting shaft 32 of the thermostatic valve core 3 are locked together by screws 8, but this is not a limitation. The handwheel 4 and the adjusting shaft 32 of the thermostatic valve core 3 can also be fixed by means of pins or buckles.

[0035] The end of the handwheel 4 away from the adjusting shaft 32 of the thermostatic valve core 3 is detachably fitted with a cover plate 9, which covers the screw 8 to protect the screw 8 from moisture and rust.

[0036] Furthermore, the present invention may also include a temperature limiting ring 6, which is sleeved on the end of the thermostatic valve core 3 facing the handwheel 4, and the inner wall of the temperature limiting ring 6 is tightly fitted with the outer wall of the thermostatic valve core 3 to achieve precise positioning of the end of the thermostatic valve core 3; the temperature limiting ring 6 is fixed between the valve body 2 and the handwheel 4.

[0037] Next, the present invention may also include a friction ring 7, which is clamped between the handwheel 4 and the shower body 1. The assembly pressure of the handwheel 4 makes the two end faces of the friction ring 7 fit tightly against the inner side wall of the handwheel 4 and the corresponding end face of the shower body 1, respectively. By utilizing the friction coefficient characteristics of the friction ring 7 itself, it provides appropriate damping for the rotation of the handwheel 4, preventing the handwheel 4 from rotating erroneously due to vibration and other factors. At the same time, it reduces the direct frictional loss between the handwheel 4 and the shower body 1, and extends the service life of the components.

[0038] The sidewall of the temperature limiting ring 6 may be provided with raised ribs 61, and the end of the valve body 2 facing the handwheel 4 is provided with a groove 21. The raised ribs 61 are inserted into the groove 21. Thus, the radial angle of the thermostatic valve core 3 is fixed by the cooperation between the groove 21 and the raised ribs 61, ensuring the angle of the handwheel 4 after installation, and controlling the alignment of the screw hole 31 of the thermostatic valve core 3 with the second through hole 22 of the valve body 2, so as to facilitate the subsequent installation of the knob 5, ensuring that the temperature limiting ring 6 does not move axially after assembly, thereby stably performing the temperature limiting function of the thermostatic valve core 3.

[0039] In some embodiments, the temperature limiting ring 6 has a temperature adjustment band 62 recessed on the inner wall of the handwheel 4. The handwheel 4 is equipped with a button 42 and has a cavity 43. The button 42 protrudes partially from the handwheel 4. An elastic element 44 is installed between the bottom of the button 42 and the bottom of the cavity 43. A pin 45 is inserted into the area of ​​the button 42 that extends into the handwheel 4. When the button 42 is pressed, the elastic element 44 is compressed, and the pin 45 moves inward from the first end 621 of the temperature adjustment band 62 into the temperature adjustment band 62. The pin 45 can move within the temperature adjustment band 62 and is restricted by the second end 622 of the temperature adjustment band 62. The elastic element 44 is preferably a spring.

[0040] The water temperature adjustment of this quick-release shower head relies on the rotation stroke of the adjusting shaft 32. When the first end 621 of the temperature adjustment band 62 abuts against the pin 45, preventing the handwheel 4 from rotating, the water temperature corresponding to the rotation stroke of the adjusting shaft 32 is exactly the highest water temperature in the normal temperature range, such as 40℃. When the user presses the button 42, the button 42 moves downward against the elastic force of the elastic element 44, compressing the elastic element 44 and simultaneously driving the pin 45 to move inward from the first end 621 of the temperature adjustment band 62, entering the temperature range. Within the temperature adjustment band 62, the user can rotate the handwheel 4, causing the pin 45 to move within the temperature adjustment band 62 until the second end 622 of the temperature adjustment band 62 blocks the pin 45, preventing the handwheel 4 from rotating further. In this case, the water temperature corresponding to the rotation stroke of the adjustment shaft 32 is exactly the highest temperature of the high temperature range, such as 49℃. When the user releases the button 42, the elastic element 44 resets, pushing the button 42 and the pin 45 upwards. The pin 45 then engages again with the first end 621 of the temperature adjustment band 62, achieving precise adjustment and locking of the temperature setting.

[0041] Please see Figure 6 The first embodiment of this utility model shown is an operating part, which is a rotating convex strip 51; please refer to... Figure 7 As shown in the second embodiment of this utility model, the operating part is a rotating groove 52, which can be rotated directly by scissors or coins.

[0042] In addition, the shower body 1 of this utility model is also provided with a cold water channel 13, a hot water channel 14, and a water outlet channel; the water in the cold water channel 13 and the water in the hot water channel 14 will flow into the mixing chamber of the thermostatic valve core 3, mix, and then exit from the water outlet channel. One end of the shower body 1 is connected to the cold water channel 13, and the other end of the shower body 1 is connected to the hot water channel 14 so that the water inlets of the cold water channel 13 and the hot water channel 14 are set far apart from each other; the thermostatic valve core 3 is arranged on the path close to the hot water channel 14 and is located at the junction of the hot water channel 14, the cold water channel 13, and the water outlet channel; the cold water channel 13 is provided with an adjustment mechanism for adjusting the amount of cold water entering the mixing chamber. The adjustment mechanism is a flow regulating valve 15 with opening and closing function. The water outlet channel is provided with multiple water passages along the water outlet direction. The shower body 1 is provided with a water outlet connector 16 connected to the water passages, and a valve core 17 for independently controlling the water outlet of each water passage to its respective water outlet connector 16; wherein, in Figure 4 , Figure 6 and Figure 7 In the embodiment shown, there are two upper water outlet connectors. Figure 1 and Figure 5 In the embodiment shown, the number of upper water outlet connectors is one.
