Description

Technical Field

[0001] This utility model relates to the field of thermostatic valves, and in particular to a digital display thermostatic valve that is easy to disassemble and assemble. Background Technology

[0002] Currently, household warm water is mainly obtained by heating municipal water supply with electricity, gas, or solar water heaters to produce high-temperature water, which is then mixed with the low-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. Existing digital display thermostatic valves include a housing, valve body, thermostatic valve core, display screen, temperature sensor, and battery pack. The battery pack powers the display screen and temperature sensor. If the display screen and temperature sensor are constantly active, most of the battery's energy will be wasted, and frequent battery replacements are necessary. Therefore, existing technology provides a water flow generator that uses the flow of water to generate power. However, existing thermostatic valves with this water flow generator suffer from difficulties in disassembly and assembly. Achieving both a reasonable arrangement of the water flow generator and the thermostatic valve core, along with quick and easy disassembly and assembly, represents a current technological breakthrough for thermostatic valves. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a digital display thermostatic valve that is reasonably arranged, compact in structure, short in flow path, and easy to disassemble and assemble by separating the water flow generator and the thermostatic valve core.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: an easily detachable digital display thermostatic valve, including a housing, a valve body, a thermostatic valve core, a display screen, a temperature sensor, and a water flow generator. The valve body is provided with a cold water inlet, a hot water inlet, and a warm water outlet. The thermostatic valve core is connected to the cold water inlet, the hot water inlet, and the warm water outlet.

[0005] The valve body is an integral valve body. One side of the valve body is provided with a valve core receiving cavity for accommodating the thermostatic valve core. The thermostatic valve core is inserted into the valve core receiving cavity. The thermostatic valve core is detachably connected to the valve core receiving cavity through a pressure cap thread. The pressure cap rotating part at the outer end of the pressure cap is located outside the valve body and the housing. The outer end of the pressure cap is provided with a thermostatic valve core handwheel that is fixedly connected to the thermostatic valve core.

[0006] The valve body has a generator housing cavity on the other side to accommodate the water flow generator. The inner end of the water flow generator is inserted into the generator housing cavity and its inner end face is sealed against the valve body. The external thread of the water flow generator is detachably connected to the generator housing cavity, and the generator rotating part at the outer end is located outside the housing. A water flow channel is provided between the water inlet end of the generator housing cavity and the water mixing outlet end of the valve core housing cavity. The water outlet end of the generator housing cavity is connected to the warm water outlet. The temperature sensor is located in the flow channel between the water inlet end and the water outlet end inside the water flow generator.

[0007] As a preferred technical solution, the front outer surface of the housing is provided with an inwardly recessed display receiving groove, and the display screen is pressed into the display receiving groove by the front outer surface of the housing. The display receiving groove is provided with wire passing holes.

[0008] As a preferred technical solution, the display screen is electrically connected to the water flow generator via a wire connector, and the display screen is electrically connected to the temperature sensor via a wire connector.

[0009] As a preferred technical solution, a sealing element is provided between the exterior of the water flow generator and the generator housing cavity, and a filter screen is provided at the water inlet end of the water flow generator.

[0010] As a preferred technical solution, the water passage is located on the side wall of the generator housing cavity, corresponding to the water inlet end of the water flow generator located on the periphery; or the water passage is located at the inner end of the generator housing cavity, corresponding to the water inlet end of the water flow generator located at the bottom.

[0011] As a preferred technical solution, the rotating part of the generator is a circumferentially arranged external tooth or a polygonal shape.

[0012] As a preferred technical solution, the pressure cap is in the shape of a hollow column, and the outer peripheral wall of the inner end of the pressure cap is provided with a pressure cap thread that is threadedly connected to the valve core receiving cavity. The pressure cap rotating part is provided on the outer peripheral wall of the pressure cap.

[0013] As a preferred technical solution, the thermostatic valve core handwheel includes a handwheel housing and a torsion bar. The torsion bar is a hollow column. The temperature adjustment handle of the thermostatic valve core is inserted into the inner end of the torsion bar. The mating surfaces of the temperature adjustment handle and the torsion bar are toothed. Fasteners enter the torsion bar from the outer end of the torsion bar to fix the temperature adjustment handle to the torsion bar.

[0014] As a preferred technical solution, the inner wall of the valve core receiving cavity is provided with an axial positioning groove, and the outer wall of the thermostatic valve core is provided with a corresponding positioning protrusion, the positioning protrusion cooperating with the positioning groove.

[0015] As a preferred technical solution, the pressure cap rotating part is a circumferentially arranged external tooth or polygonal shape.

[0016] Positioning the valve core housing and the generator housing on the left and right sides of the valve body, respectively, offers two advantages: First, the disassembly and assembly directions of the thermostatic valve core and the water flow generator are parallel to the wall, facilitating direct hand operation to disassemble and assemble them from the side. After removing the housing, the replacement of the water flow generator and thermostatic valve core can be achieved without disassembling the valve body, making disassembly and assembly convenient and easy to maintain. Second, disassembling and assembling the thermostatic valve core and the water flow generator from the two sides is independent and does not interfere with each other. Furthermore, the generator housing is located close to the inner end of the valve core housing and positioned between the valve core housing and the warm water outlet, resulting in a reasonable layout and compact structure. This shortens the water flow path between the thermostatic valve core and the water flow generator, minimizing the size of the thermostatic valve while ensuring accurate measurement of the outlet water temperature.

Detailed Implementation

[0030] 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.

[0031] Example 1:

[0032] like Figures 1 to 6 As shown, an easily detachable digital display thermostatic valve includes a housing 1, a valve body 2, a thermostatic valve core 3, a display screen 4, a temperature sensor (not shown in the figure), and a water jet generator 5. The valve body 2 has a cold water inlet 6, a hot water inlet 7, and a warm water outlet 8. The thermostatic valve core 3 connects the cold water inlet 6, the hot water inlet 7, and the warm water outlet 8. Cold water enters the thermostatic valve core 3 through the cold water inlet 6, and hot water enters the thermostatic valve core 3 through the hot water inlet 7. After mixing in the thermostatic valve core 3, warm water is formed and discharged from the warm water outlet 8 for user use. In this embodiment, a thermostatic valve is used as a carrier, and a water jet generator 5, a temperature sensor, and a display screen 4 are installed on it. The electrical energy generated by the water jet generator 5 drives the temperature sensor and the display screen 4, so that the temperature of the mixed water detected by the temperature sensor can be directly displayed on the display screen 4.

[0033] See Figure 4 and Figure 5The valve body 2 is a one-piece valve body. The right end of the valve body 2 has a valve core receiving cavity 9 for accommodating the thermostatic valve core 3. The opening of the valve core receiving cavity 9 faces right. The thermostatic valve core 3 can be disassembled from within the valve core receiving cavity 9, i.e., disassembled from the right side of the valve body 2. The left end of the valve body 2 has a generator receiving cavity 10 for accommodating the water flow generator 5. The opening of the generator receiving cavity 10 faces left. The generator receiving cavity 10 is located near the inner end of the valve core receiving cavity 9 and is positioned between the inner end of the valve core receiving cavity 9 and the warm water outlet 8. The water flow generator 5 can be disassembled from within the generator receiving cavity 10, i.e., disassembled from the left side of the valve body 2. Alternatively, the valve core receiving cavity 9 can be located at the left end of the valve body 2, and the generator receiving cavity 10 at the right end of the valve body 2.

[0034] The advantages of placing the valve core cavity 9 and the generator cavity 10 on the left and right sides of the valve body 2 are as follows: First, the disassembly and assembly directions of the thermostatic valve core 3 and the water flow generator 5 are parallel to the wall, which facilitates direct disassembly and assembly of the thermostatic valve core 3 and the water flow generator 5 from the side. After removing the housing 1, the replacement of the water flow generator 5 and the thermostatic valve core 3 can be met without disassembling the valve body 2. The disassembly and assembly are convenient and easy to maintain. Second, the disassembly and assembly of the thermostatic valve core 3 and the water flow generator 5 from the sides are independent and do not interfere with each other. At the same time, the generator cavity 10 is close to the inner end of the valve core cavity 9 and is located between the inner end of the valve core cavity 9 and the warm water outlet 8. It has the characteristics of reasonable arrangement and compact structure, shortens the water flow path between the thermostatic valve core 3 and the water flow generator 5, ensures that the area of ​​the thermostatic valve body 2 is minimized, and the outlet water temperature is accurately measured.

[0035] See Figure 6 and Figure 7 The valve body 2 is an integral valve body. The left side of the valve body 2 is provided with a generator receiving cavity 10 for accommodating the water flow generator 5. The inner end of the water flow generator 5 is inserted into the generator receiving cavity 10 and the inner end face is sealed against the valve body 2. The external thread of the water flow generator 5 is detachably connected to the generator receiving cavity 10, and the generator rotating part 51 at the outer end is located outside the housing 1. A water passage 11 is provided between the water inlet end of the generator receiving cavity 10 and the mixing water outlet end of the valve core receiving cavity 9. The water outlet end of the generator receiving cavity 10 is connected to the warm water outlet 8. By reasonably arranging the water passage 11, it is ensured that the hot water in the mixing water outlet end of the thermostatic valve core 3 can stably enter the water flow generator 5 to drive the water flow generator 5 to work.

[0036] See Figure 7 and Figure 8The valve body 2 is a one-piece valve body, and the generator housing 10 is formed in one step during the processing of the valve body 2, which is convenient to process, low in cost, and has high structural strength. The outer peripheral wall of the water flow generator 5 near its outer end has a threaded section 52 that connects to the generator housing 10. During installation, the water flow generator 5 is simply inserted into the generator housing 10 from the outside to the inside and then tightened with the threads to secure it in the generator housing 10. The inner end face sealing ring 53 of the water flow generator 5 abuts against the shoulder of the valve body 2, and the outer peripheral sealing element 54 of the water flow generator 5 abuts against the outer peripheral side of the generator housing 10. This double sealing facilitates positioning and installation while ensuring airtightness. The sealing element 54 is also a sealing ring.

[0037] See Figure 7 and Figure 8 The outer end of the water flow generator 5 ( Figure 7 The left end of the middle section is provided with a generator rotating part 51. The generator rotating part 51 is located outside the housing 1. It is used to facilitate the threaded disassembly and assembly of the water flow generator 5. Its structure can be circumferentially set external teeth or polygonal shape. The polygonal shape can be external hexagonal, which makes it convenient for the wrench to be operated directly from the outside.

[0038] See Figure 7 and Figure 8 In this embodiment, the water flow generator 5 adopts a side-inlet and bottom-outlet structure, which is a product known in the prior art. In this case, the water flow channel 11 is located on the side wall of the generator housing 10, corresponding to the water inlet end of the water flow generator 5 located on the periphery. The inner end of the generator housing 10 is adjacent to the bottom end of the water flow generator 5. Figure 7 The water outlet is located at the right end of the middle section; the water inlet of the water generator 5 is equipped with a filter screen 55. For this type of water generator 5 with side water inlet and bottom water outlet, the filter screen 55 is located on the outer circumferential surface of the water inlet of the water generator 5.

[0039] When the tap is turned on, the water pressure can reach 3-5 kg. However, the current water flow generator 5 is designed to be more sensitive and only requires 1 kg of water pressure to start. Therefore, the water flow generator 5 can meet the usage requirements when applied to thermostatic valves, achieving the effect of generating electricity as soon as water comes out of the tap.

[0040] In this embodiment, the temperature sensor is integrated inside the water flow generator 5. When the water flow generator 5 generates electricity, the temperature sensor is energized and can measure the temperature. The probe of the temperature sensor is placed in the flow channel between the inlet and outlet of the water flow generator 5. This location is reasonable and does not affect the quick installation of the water flow generator 5. At the same time, it can measure the temperature of the flowing water. Furthermore, since the water flow generator 5 is located between the mixing outlet and the warm water outlet 8 of the thermostatic valve core 3, the temperature sensor is placed in this position, and its temperature measurement is more accurate.

[0041] See Figure 2 The outer front surface of the housing 1 has an inwardly recessed display receiving groove 12. The display screen 4 is pressed into the display receiving groove 12 by the outer front surface of the housing 1. The display receiving groove 12 has a wire passing hole 13 for wires to pass through. This installation method also facilitates the replacement of the display screen 4.

[0042] See Figure 2 The outer surface of the front end of the housing 1 is also provided with a display screen film or display screen cover 14. The display screen film or display screen cover 14 can be made of transparent material, which does not affect the coverage of the display screen 4, and can also perform front-end positioning and moisture-proof treatment of the display screen 4; 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 4.

[0043] The display screen 4 is electrically connected to the water flow generator 5 via a wire connector 1, and the display screen 4 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.

[0044] The display screen 4 is a liquid crystal display screen 4 or an LED display screen 4. In this embodiment, the display screen 4 is located in the upper middle part of the front end face of the housing 1, but it can also be located on the left or right side.

[0045] The housing 1 is installed by a front cover and a rear cover that snap together, making it easy to disassemble. In this embodiment, the housing 1 is cuboid in shape, but it can also be other shapes.

[0046] See Figures 4 to 6The valve body 2 is an integral valve body. The right side of the valve body 2 is provided with a valve core receiving cavity 9 for accommodating the thermostatic valve core 3. The thermostatic valve core 3 is inserted into the valve core receiving cavity 9. The thermostatic valve core 3 is detachably connected to the valve core receiving cavity 9 by a pressure cap 15 threadedly. The pressure cap rotating part 151 at the outer end of the pressure cap 15 is located outside the valve body 2 and the housing 1. The outer end of the pressure cap 15 is provided with a thermostatic valve core handwheel 16 fixedly connected to the thermostatic valve core 3. The thermostatic valve core 3, the pressure cap 15 and the thermostatic valve core handwheel 16 cooperate to form a thermostatic valve assembly that is easy to disassemble and assemble. The thermostatic valve core 3 is installed in the valve core receiving cavity 9 by the pressure cap 15, realizing the quick insertion of the thermostatic valve core 3.

[0047] The thermostatic valve core 3 includes a valve core seat, a thermosensitive element, a return spring, a limiting assembly, and a valve core housing 1, which are products disclosed in this field and will not be described in detail here.

[0048] The pressure cap 15 is a hollow column. The outer peripheral wall of the inner end of the pressure cap 15 is provided with a pressure cap thread 152 that is threadedly connected to the valve core receiving cavity 9. The pressure cap rotating part 151 is provided on the outer peripheral wall of the pressure cap 15.

[0049] The thermostatic valve core handwheel 16 includes a handwheel housing 161 and a torsion bar 162. The torsion bar 162 is a hollow column. The temperature adjustment handle 31 of the thermostatic valve core 3 is inserted into the inner end of the torsion bar 162. The mating surfaces of the temperature adjustment handle 31 and the torsion bar 162 are toothed. The outer peripheral wall of the temperature adjustment handle 31 has external teeth, and the inner wall of the inner end of the torsion bar 162 has a corresponding internal tooth structure. A fastener 17 enters the torsion bar 162 from the outer end of the torsion bar 162 to fix the temperature adjustment handle 31 to the torsion bar 162. A removable pressure cap 163 is installed at the outer opening end of the handwheel housing 161. The fastener 17 is a screw, which has a nut and a screw. Fastener 17 enters torsion bar 162 along the outside of torsion bar 162, nut is placed on limit step, screw passes through limit step and is connected and fixed to temperature control handle 31, temperature control handle 31 has a threaded hole with opening to the right in the middle and corresponding thread.

[0050] The inner wall of the valve core receiving cavity 9 is provided with an axial positioning groove, and the outer wall of the thermostatic valve core 3 is provided with a corresponding positioning protrusion. The positioning protrusion cooperates with the positioning groove to perform circumferential positioning of the thermostatic valve core 3.

[0051] The pressure cap rotating part 151 has circumferentially arranged external teeth or a polygonal shape.

[0052] When it is necessary to adjust the outlet water temperature of the thermostatic valve core 3, simply rotate the handwheel housing 161, and the temperature adjustment handle 31 will be rotated through the torsion bar 162 and the fastener 17 to achieve the purpose of adjusting the outlet water temperature.

[0053] When the thermostatic valve needs to be disassembled, first remove the cap 163 of the handwheel housing 161, loosen the fastener 17, and then disassemble the thermostatic valve core handwheel 16. Next, use a wrench 18 to loosen the cap 15 outwards via the cap rotating part 151. After the cap 15 is removed, the thermostatic valve core 3 can be directly slid out and disassembled without any positioning. During installation, first slide the thermostatic valve core 3 laterally into the valve core receiving cavity 9, then fix the cap thread 152 into the valve core receiving cavity 9, using the cap 15 to axially position the valve core. Finally, use the fastener 17 to fix the thermostatic valve core handwheel 16 to the temperature control handle 31. The overall disassembly and assembly process is simple. During the disassembly of the thermostatic valve core 3, there is no need to disassemble the housing 1 or the valve body 2. With the valve body 2 and housing 1 still installed, the thermostatic valve core 3 can be directly disassembled and assembled, which is beneficial for users to perform disassembly and assembly themselves.

[0054] In this embodiment, the axis of the valve core receiving cavity 9 is parallel to the axis of the generator receiving cavity 10 vertically, and the two axes are on the same plane in the front-back direction. This arrangement has two advantages: Firstly, by taking advantage of the characteristic of the vertically parallel misalignment of the axes, the water flow channel 11 is set at the position between the misalignment of the axes, which can make full use of the space of the valve body 2 to arrange the receiving cavity, ensuring that the thermostatic valve has a compact structure and a short water flow path in the water flow channel 11; Secondly, the opening of the water flow channel 11 connecting the valve core receiving cavity 9 and the generator receiving cavity 10 is also on the plane of the two axes, which can reduce water resistance, and the water in the valve core receiving cavity 9 can quickly and smoothly enter the generator receiving cavity 10 to drive the water flow generator 5 to operate.

[0055] Example 2:

[0056] The main difference between this embodiment and Embodiment 1 lies in the structure of the water flow generator 5 and the corresponding arrangement of the water flow channel 11. See also Figure 11 In this embodiment, the water flow generator 5 adopts a bottom ( Figure 11The structure features a water inlet (right end) and a side outlet. In this configuration, the water flow channel 11 is located at the inner end of the generator housing 10, corresponding to the water inlet end of the water flow generator 5 at the bottom. The water outlet channel is located on the side wall of the generator housing 10, corresponding to the water outlet end of the water flow generator 5 on the periphery. A filter screen 55 is provided at the water inlet end of the water flow generator 5. For this type of bottom-inlet, side-outlet water flow generator 5, the filter screen 55 is located on the bottom end face of the water flow generator 5. In this embodiment, the axis of the generator housing 10 coincides with the axis of the valve core housing 9. This allows for a significant reduction in the space of the water flow channel 11, ensuring structural compactness. Simultaneously, warm water from the valve core housing 9 can directly flow into the generator housing 10, resulting in low water resistance.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
