Description

Technical Field

[0001] This utility model relates to the field of thermostatic valves, and in particular to a battery-operated digital display thermostatic valve. Background Technology

[0002] Currently, household warm water is mainly obtained by heating municipal water supply with electric, gas, or solar water heaters to produce high-temperature water, which is then mixed with the lower-temperature municipal water supply to obtain usable warm water. The temperature of the warm water can be adjusted by changing the mixing ratio of the high-temperature water and the municipal water supply. Currently, digital display thermostatic valves are mainly used for mixing high-temperature water and municipal water supply.

[0003] The prior art, CN 213900080 U, discloses a thermostatic valve with a temperature display function. This design includes a thermostatic valve body, a front cover, a rear cover, a display, a temperature sensor, and a power supply. The thermostatic valve body has a temperature measuring hole on its warm water outlet pipe, into which the temperature sensor is inserted to measure the temperature of the flowing warm water. The front cover has a display window, and the display is mounted on the back of the front cover, with its screen facing the display window. The rear cover has a battery compartment, where the power supply is installed. This design uses a thermostatic valve as a base, with the display and temperature sensor powered by a battery. This design has several problems: 1. The battery compartment is located on the back of the valve body, which is inconvenient for disassembly. Replacing the battery requires disassembling the thermostatic valve first, making the battery replacement process complex. 2. Currently, the batteries in thermostatic valves are mainly rechargeable batteries, which are relatively large and affect the internal valve body layout. 3. If the display and temperature sensor are constantly in operation, most of the battery's energy will be wasted, and frequent battery replacements are necessary. Therefore, this application provides a quick-release, compact battery-operated digital display thermostatic valve that allows for rapid battery replacement without disassembling the valve body, facilitating user replacement. Furthermore, the use of button batteries minimizes space occupation and does not affect the internal valve body layout. Additionally, the display screen can be turned on and off according to user needs, saving energy and reducing battery replacement frequency. Summary of the Invention

Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0033] Example 1:

[0034] like Figures 1 to 3As shown, a battery-operated quick-release digital display thermostatic valve includes a housing 1, a valve body 2, a thermostatic valve core, a display component, a temperature sensor, and a battery. The valve body 2 has a cold water inlet pipe 3, a hot water inlet pipe 4, and a warm water outlet pipe 5. The thermostatic valve core connects to the cold water inlet pipe 3, the hot water inlet pipe 4, and the warm water outlet pipe 5. The housing 1 includes a front cover and a rear cover, which are fastened together with screws. The thermostatic valve core is located inside the valve body 2, and the valve body 2 is located inside the housing 1. The battery is located inside the housing 1 near the rear cover and provides power to the temperature sensor and the display component. The temperature sensor is located at the warm water outlet pipe 5 and is used to detect the outlet water temperature. The display component is located on the front cover and is used to display the outlet water temperature. The temperature sensor is a temperature probe located at the warm water outlet pipe 5, which is prior art and is not shown in the figure.

[0035] See Figures 4 to 8 The housing 1 has a battery slot 6 on its surface. Inside the housing 1, corresponding to the battery slot 6, there is a battery base 7 and a battery mounting base 8. The battery mounting base 8 is detachably mounted to the battery base 7 from outside the housing 1 through the battery slot 6. The battery is a button cell battery 9, which is detachably mounted in the battery mounting base 8. The battery base 7 has conductive terminals 10 that are electrically connected to the button cell battery 9. The conductive terminals 10 are also electrically connected to the display component. During installation, the button cell battery 9 is first placed in the battery mounting base 8, and then the battery mounting base 8 is inserted into the battery base 7 through the battery slot 6 on the side of the housing 1. After full insertion, the conductive terminals 10 contact the button cell battery 9, providing power to the display component and temperature sensor.

[0036] This utility model allows for the direct removal and installation of the battery without disassembling the valve body 2, by placing the battery on the side of the housing 1 and installing it on or removing it from the battery base 7 via the battery mounting seat 8. This achieves the purpose of quick battery replacement and facilitates user replacement operations.

[0037] This utility model uses a button battery 9 instead of a storage battery, which occupies less space and is placed on the side of the housing 1. The gap between the valve body 2 and the thermostatic valve housing 1 is sufficient to accommodate the installation of the button battery 9. This ensures that the layout of the internal valve body 2 is not affected without changing the original thermostatic valve housing 1. It has the advantages of compact structure and reasonable layout.

[0038] In this embodiment, the battery base 7, the battery mounting base 8, and the button battery 9 are all placed vertically and close to the rear end of the housing 1. When placed vertically, they are parallel to the front and rear end faces of the housing 1, effectively utilizing the gap between the valve body 2 and the housing 1 for layout, thus achieving the purpose of space rationalization.

[0039] See Figure 5 and Figure 6 The battery slot 6 is located at the side rear corner of the housing 1. The outer end of the battery mounting base 8 is provided with an L-shaped cover plate 8a that covers the battery slot 6. The rear surface of the L-shaped cover plate 8a is provided with anti-slip texture, so that the user can push the battery mounting base 8 out directly with their fingers.

[0040] See Figure 5 and Figure 6 The L-shaped cover plate 8a is also provided with a plug-in part 8b that is inserted into the battery base 7. The plug-in part 8b is provided with an annular groove 8c for accommodating the button battery 9. The rear end of the annular groove 8c is provided with a stop block 8d for limiting the button battery 9. The two end faces of the battery mounting base 8 are hollowed out to expose the positive and negative terminals of the button battery 9, which is conducive to contacting and energizing the conductive terminal 10.

[0041] See Figure 7 and Figure 8 A sealing element 11 is provided at the outer end mating surface between the battery base 7 and the battery mounting base 8. The sealing element 11 is a sealing ring. A sealing groove is provided at the outer ring position of the connection between the L-shaped cover plate 8a and the insertion part 8b. The sealing ring is installed in the sealing ring groove. When the battery mounting base 8 is fully inserted into the battery base 7, the sealing ring is pressed against the outer periphery of the battery base 7, sealing the outer end mating surface between the battery base 7 and the battery mounting base 8 to achieve waterproofing.

[0042] See Figure 7 and Figure 8 The outer edge of the battery slot 6 is provided with a slotted shoulder 6a, and the edge of the battery mounting base 8 is provided with a cover shoulder 8e that fits outside the slotted shoulder 6a. After the battery mounting base 8 is installed in place, the cover shoulder 8e contacts and fits with the slotted shoulder 6a. Through the fit between the shoulders, not only is the installation and positioning achieved, but also the purpose of waterproof sealing is achieved, serving as the first seal. The sealing element 11 serves as the second seal. The two seals work together to achieve a better waterproof effect.

[0043] See Figures 5 to 8The battery base 7 has a fixing ear 7a on its outside. The fixing ear 7a is connected to the back cover of the housing 1 by screws to fix the battery base 7. The battery base 7 has a cavity inside for accommodating the battery mounting seat 8. The outer end of the battery base 7 has a base opening 7b corresponding to the battery slot 6. The battery mounting seat 8 extends into the interior of the battery base 7 through the base opening 7b. The inner end of the battery base 7 has a wire opening 7c. The wire is connected to the conductive terminal 10 through the wire opening 7c.

[0044] See Figure 8 The conductive terminal 10 includes a positive electrode spring 10a and a negative electrode spring 10b. The positive electrode spring 10a and the negative electrode spring 10b are located on both sides of the button battery 9 and press against the positive and negative terminals of the button battery 9. The positive electrode spring 10a and the negative electrode spring 10b are V-shaped, and the button battery 9 is pressed and positioned and energized through the V-shaped tips. When the battery mounting base 8 with the button battery 9 is fully inserted into the battery base 7, the positive electrode spring 10a and the negative electrode spring 10b cooperate to clamp and fix the button battery 9, thereby indirectly fixing the battery mounting base 8. This provides lateral damping to prevent the battery mounting base 8 from falling off on its own.

[0045] See Figure 9The display assembly includes a display circuit board 12 and a display screen 13, a switch 14, and a controller 15 disposed on the display circuit board 12. The display circuit board 12 is electrically connected to the positive electrode spring 10a and the negative electrode spring 10b. The display circuit board 12 is also electrically connected to a temperature sensor. When powered by a battery, the temperature sensor is powered through the display circuit board 12. The switch 14 and the display screen 13 are both connected to the controller 15. The switch 14 controls the display screen 13 to power on and display. The switch 14 can be a button or a touch button. The top of the switch 14 is exposed outside the housing 1 for easy hand operation. The controller 15 controls the power-on display time of the display screen 13. The display screen 13 can be set to be constantly lit for 1 minute. Of course, the power-on display time can be set to 2 minutes or other values ​​as needed. When a user wants to check the water temperature while showering, they press the switch 14. The display screen 13 lights up and shows the temperature value, remaining constantly lit for 1 minute. After 1 minute, the display screen 13 dims. To check the water temperature again, the user simply presses the switch 14. This embodiment uses the switch 14 to control the display screen 13, allowing the user to control the intermittent temperature display. Compared to the always-on display screen method in existing technologies, this saves power and reduces the frequency of battery replacements.

[0046] See Figure 3 The front surface of the housing 1 is provided with a display groove 16, the display circuit board 12 is located in the display groove 16 and is fixed by screws, and the display groove 16 is also provided with a wire opening 2 17, through which the wire is connected to the conductive terminal 10 and the temperature sensor.

[0047] See Figure 3 The outer surface of the front end of the housing 1 is also provided with a display screen film or display screen cover 18. The display screen film or display screen cover 18 can be made of transparent material, which does not affect the coverage of the display screen 13, and can also perform front-end positioning and moisture-proof treatment of the display screen 13; or it can be made of non-transparent material, with a screen display area on the surface, which can position, shield and prevent moisture from the outer ring of the display screen 13.

[0048] The display screen 13 is electrically connected to the display circuit board 12 via a wire connector 1, and the display circuit board 12 is electrically connected to the temperature sensor via a wire connector 2. Both wire connector 1 and wire connector 2 are quick connectors commonly used in the prior art, with male and female connectors that can be plugged in for quick and easy connection.

[0049] The display screen 13 is either a liquid crystal display screen or an LED display screen, and both types of display screens are within the protection scope of this application.

[0050] Example 2:

[0051] The main difference between this embodiment and Embodiment 1 lies in the structure of the display component. In this embodiment, the display component includes a display screen 13, which is electrically connected to the conductive terminal 10. This embodiment does not include a display circuit board 12, a switch 14, or a controller 15. The display screen 13 is mounted and pressed into the display recess 16. The button battery 9 is directly connected to the display screen 13 via the conductive terminal 10 and wires to power the display screen 13. Simultaneously, the button battery 9 is also directly connected to a temperature sensor to power the temperature sensor. In this embodiment, the display screen 13 is a constantly lit display screen 13.

[0052] Example 3:

[0053] The main difference between this embodiment and Embodiment 1 lies in the structure of the display component. In this embodiment, the display component includes a display circuit board 12, a display screen 13 disposed on the display circuit board 12, and a switch 14. The display circuit board 12 is electrically connected to the conductive terminal 10. The switch 14 controls the display screen 13 to turn on. In this embodiment, there is no controller 15, but other connection methods are the same as in Embodiment 1. In this embodiment, the lighting and dimming of the display screen 13 are directly controlled by the switch 14. Pressing the switch 14 once lights up the display screen 13, and pressing it again dims the display screen 13. The switch 14 also helps to save power.
