Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus detailed descriptions thereof will be omitted.

The embodiment of the utility model provides a gas-liquid mixing device, which increases the flow rate of liquid by reducing the flow area of the liquid, thereby reducing the pressure of the liquid and further reducing the difficulty of mixing gas entering the liquid.

It can be understood that in the gas-liquid mixing device according to the embodiment of the utility model, the gas may be carbon dioxide gas, the liquid may be water, and the carbon dioxide gas and the water form a carbonated spring after being mixed. Of course, the gas and the liquid are not limited to carbon dioxide gas and water, and the gas may be other gases that are soluble in water or other liquids.

In addition, when the gas is carbon dioxide gas and the liquid is water, the gas-liquid mixing device can be applied to a shower or a hot spring device for manufacturing a carbonated spring.

Of course, the gas-liquid mixing device of the present utility model can also be applied to other fields of gas-liquid mixing, and is not listed here.

For convenience of explanation, the following description will be given by taking the application of the gas-liquid mixing device to the carbonated spring shower as an example, but the utility model is not limited thereto.

As shown in fig. 1 to 3, fig. 1 is a schematic view showing a gas-liquid mixing apparatus according to a first embodiment of the present utility model, and fig. 2 and 3 are schematic views showing fig. 1 from two different angles of view with the housing 10 and the hand shower 50 removed. The gas-liquid mixing device of the embodiment of the utility model comprises a shell 10, a gas supply assembly 20, a liquid supply assembly 30, a mixing assembly 40, a second switch valve 60 and a hand-held shower 50.

It will be understood that the terms "comprising," "including," and "having," and any variations thereof, are intended to cover non-exclusive inclusions in the embodiments of the utility model. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may alternatively include other steps or elements not listed or inherent to such process, method, article, or apparatus.

The housing 10 may be made of a plastic material or a metal material. The housing 10 has a chamber for housing the air supply assembly 20, the liquid supply assembly 30, and the mixing assembly 40.

The liquid supply assembly 30 includes a hot water connection 311, a cold water connection 312, a thermostat valve 320, a generator 330, a display screen 340, and a waterway pressure-reducing valve 350. The hot water joint 311 is used to connect a hot water pipe, and the cold water joint 312 is used to connect a cold water pipe. The hot water connector 311 and the cold water connector 312 are both connected to the temperature adjusting valve 320, and hot water and cold water are mixed at the temperature adjusting valve 320 to form mixed water. The temperature of the mixed water can be regulated by a user according to own habits. Further, the solubility of carbon dioxide gas dissolved in water is inversely proportional to the temperature of water, so that the temperature of the mixed water can be controlled by adjusting the temperature-adjusting valve 320, thereby avoiding the influence of the excessive temperature on the solubility of carbon dioxide gas.

The inlet of the generator 330 is connected to the outlet of the temperature-adjusting valve 320, and the generator 330 is used to generate electric power using the flow rate of the mixed water. The display screen 340 is electrically connected with the generator 330 and exposed to the housing 10 for a user to observe, and the display screen 340 is used for displaying the temperature and flow rate of the mixed water.

An inlet of the waterway pressure reducing valve 350 is connected to an outlet of the generator 330, and an outlet of the waterway pressure reducing valve 350 is connected to the liquid inlet channel 412 of the mixing assembly 40. The waterway pressure reducing valve 350 is used to reduce the pressure of the mixed water, for example, to below 2.5 Bar.

The mixed water formed by mixing the cold water and the hot water sequentially passes through the generator 330 and the waterway pressure reducing valve 350 and then enters the mixing assembly 40.

The gas supply assembly 20 includes a gas supply unit 210 and a linkage valve 220, the gas supply unit 210 being in communication with a gas inlet passage 413 of the mixing assembly 40 through the linkage valve 220 for supplying gas into the mixing assembly 40.

The gas supply unit 210 includes a gas inlet joint 250 (fig. 10 and 11), a first switching valve 290, and a gas source unit 280. The air inlet connector 250 and the first switching valve 290 are sequentially communicated, and an outlet of the first switching valve 290 is communicated with the air inlet 233 of the linkage valve 220. The gas source unit 280 stores gas and is detachably connected to the gas inlet joint 250 for supplying the gas to the gas inlet joint 250.

By the design that the air source unit 280 is detachably connected to the air inlet connector 250, the air source unit 280 can be replaced in time when the air stored in the air source unit 280 is insufficient.

The inlet of the second switch valve 60 is connected to the liquid outlet passage 414 of the mixing assembly 40, and the hand shower 50 is connected to the outlet of the second switch valve 60. When the second switching valve 60 is opened, the mixed water flows to the hand shower 50 for the user to shower.

As shown in fig. 4 to 6, fig. 4 is a cross-sectional view taken along A-A in fig. 1, in which the hand shower 50 is omitted. Fig. 5 shows a partial enlarged view at X1 in fig. 4. Fig. 6 shows a schematic perspective view of a hybrid 410. In this embodiment, the mixing assembly 40 includes a mixing body 410, a mixing joint 420, a first opening and closing unit 430, and an air outlet plate 440.

One end of the mixing joint 420 is connected to the mixing body 410, and the mixing joint 420 and the mixing body 410 together form the liquid inlet channel 412. The other end of the mixing joint 420 is connected to the outlet of the waterway pressure reducing valve 350.

The mixing body 410 has a mixing channel 411, an intake channel 413 and a discharge channel 414. The liquid inlet passage 412, the air inlet passage 413, and the liquid outlet passage 414 are respectively communicated with the mixing passage 411. The air inlet passage 413 communicates with the air supply assembly 20, such as the air inlet passage 413 communicates with the air outlet 234 of the linkage valve 220. The inlet passage 412 communicates with the liquid supply assembly 30, such as the inlet passage 412 communicates with the outlet of the waterway pressure reducing valve 350. Wherein the flow area of the mixing channel 411 is smaller than the flow area of the liquid inlet channel 412.

Of course, in other embodiments, the mixing assembly 40 may not include the mixing joint 420, and the mixing body 410 may have the mixing channel 411, the liquid inlet channel 412, the air inlet channel 413, and the liquid outlet channel 414.

The liquid provided by the liquid supply assembly 30 enters the mixing channel 411 through the liquid inlet channel 412, the gas provided by the gas supply assembly 20 enters the mixing channel 411 through the gas inlet channel 413, the gas and the liquid realize gas-liquid mixing in the mixing channel 411, and finally, the liquid outlet channel 414 flows out of the gas-liquid mixed water. Since the flow area of the mixing channel 411 is smaller than that of the liquid inlet channel 412, according to the bernoulli principle, liquid enters the mixing channel 411 with smaller cross-sectional area from the liquid inlet channel 412 with larger cross-sectional area, and the liquid has the characteristics of fast flow rate and small pressure.

The axes of the inlet channel 412, mixing channel 411 and outlet channel 414 are collinear to allow liquid to quickly pass through the mixing junction 420 and the mixing body 410.

The axis of the inlet passage 413 is perpendicular to the axis of the mixing passage 411. In other words, as shown in connection with fig. 5, the flow direction of the liquid is the lateral direction, the flow direction of the gas is the vertical direction, and the lateral direction is perpendicular to the vertical direction. In the mixing channel 411, the gas can be directly flushed into the liquid, further reducing the difficulty of the gas being fused into the liquid.

The mixing channel 411 has a smaller flow area than the liquid outlet channel 414. The flow area of the liquid inlet channel 412 may be greater than, equal to, or less than the flow area of the liquid outlet channel 414.

As shown in fig. 5 and 7, fig. 7 is a schematic perspective view of the air outlet piece 440. The mixing assembly 40 further includes an air outlet plate 440, and the air outlet plate 440 is disposed in the air inlet passage 413. The air outlet plate 440 is provided with a plurality of air outlet holes 441. The gas passes through the plurality of gas outlet holes 441 of the gas outlet plate 440 to form a plurality of gas streams. The multiple streams then enter mixing channel 411 where they are mixed with the liquid. The individual streams of gas are separated into multiple streams of fine gas by gas outlet plate 440 so that the gas is more easily incorporated into the liquid.

The shape of the gas outlet holes 441 may be various shapes, such as circular holes, rectangular holes, or other shapes.

The mixing assembly 40 further includes a first opening and closing unit 430 disposed in the air inlet passage 413 for opening and closing the air inlet passage 413. The first opening and closing unit 430 includes a first fixing member 431, a first stopper 432, and a first elastic member 433. The first fixing member 431 is fixedly disposed in the air inlet passage 413. The first plug 432 is disposed within the air inlet passage 413 and is movable relative to the first mount 431 between a first position and a second position. In the first position, the first stopper 432 and the first fixing member 431 block the air inlet passage 413, and in the second position, the first stopper 432 is not blocked from the air inlet passage 413 by the air pressure of the air supplied from the air supply assembly 20. The first elastic member 433 is disposed between the first stopper 432 and the first fixing member 431, and is configured to provide an elastic force to the first stopper 432 toward the first position.

When the gas supply assembly 20 does not supply the gas, the first stopper 432 is at the first position under the action of the first elastic member 433, and at this time, the first stopper 432 and the first fixing member 431 block the gas inlet passage 413. When the gas supply assembly 20 supplies the gas, the first stopper 432 is moved from the first position to the second position by the pressing of the gas pressure, and the first stopper 432 presses the first elastic member 433. A flow path for the gas to pass through is formed between the first plug 432 and the first fixing member 431, and the gas passes through the flow path into the mixing channel 411.

As an example, the first elastic member 433 may be a compression spring, but is not limited thereto.

As shown in fig. 8 and 9, fig. 8 is a cross-sectional view of the ganged valve 220 with the valve stem 242 blocking the air outlet 234. Fig. 9 shows a cross-sectional view of the ganged valve 220 with the valve stem 242 not blocking the air outlet 234. The linkage valve 220 includes a first valve body 230 and a second opening and closing unit 240, the first valve body 230 has a valve cavity 231, and a liquid inlet 232, an air inlet 233 and an air outlet 234 which are communicated with the valve cavity 231, the liquid inlet 232 is communicated with the liquid outlet passage 414, the air inlet 233 is communicated with the gas supply unit 210, and the air outlet 234 is communicated with the air inlet passage 413. The second opening and closing unit 240 is disposed in the valve cavity 231, and is configured to open the air outlet 234 when the pressure of the liquid supplied from the liquid supply assembly 30 is equal to or greater than a threshold value, and to close the air outlet 234 when the pressure of the liquid supplied from the liquid supply assembly 30 is less than the threshold value.

The liquid inlet 232 of the linkage valve 220 is communicated with the outlet of the second switch valve 60 through a pipeline. When the second switch valve 60 is opened, the liquid provided by the liquid supply assembly 30 enters the liquid inlet 232 of the linkage valve 220 through the pipeline. When the pressure of the liquid is greater than or equal to the threshold value, the second opening and closing unit 240 opens the air outlet 234, so that the air supplied from the air supply assembly 20 flows to the air inlet 413 of the mixing assembly 40 through the air outlet 234, and finally is mixed to form the carbonated spring. When the pressure of the liquid is less than the threshold value, the second opening and closing unit 240 closes the air outlet 234, and the air cannot pass through the linkage valve 220 to reach the air inlet passage 413 of the mixing assembly 40, and finally the carbonated spring cannot be formed.

The solubility of carbon dioxide gas in water is proportional to the pressure of water, i.e., the greater the pressure of water, the higher the solubility. Then, by the provision of the second opening and closing unit 240, the gas is introduced into the air inlet passage 413 of the mixing assembly 40 only when the pressure of the liquid reaches the threshold value, and the concentration of the carbonate spring is ensured.

With continued reference to fig. 8 and 9, the valve chamber 231 has a liquid storage chamber 2311, a gas storage chamber 2312, and perforations 2313 disposed in the liquid storage chamber 2311 and the gas storage chamber 2312. The liquid storage cavity 2311 is communicated with the liquid inlet 232, and the air inlet 233 and the air outlet 234 are communicated with the air storage cavity 2312.

The second opening and closing unit 240 includes a piston 241, a valve stem 242, and a second elastic member 243. The valve rod 242 is movably disposed through the through hole 2313, and an outer wall of the valve rod 242 is hermetically connected with an inner wall of the through hole 2313, for example, a sealing ring is disposed between the valve rod 242 and the through hole 2313. The piston 241 is disposed in the liquid storage chamber 2311 and fixedly connected to the valve rod 242. The piston 241 and the valve rod 242 are movable relative to the first valve body 230 between a third position in which the valve rod 242 blocks the air outlet 234 and a fourth position in which the piston 241 is forced by the pressure of the liquid provided by the liquid supply assembly 30 within the liquid storage chamber 2311 to move the valve rod 242 without blocking the air outlet 234. The second elastic member 243 is disposed between the first valve body 230 and the piston 241, for providing an elastic force to the piston 241 to move toward the fourth position.

Liquid enters the liquid storage cavity 2311 from the liquid inlet 232, if the pressure of the liquid is smaller than the threshold value, the pressure of the liquid cannot overcome the elastic force of the second elastic member 243 to squeeze the piston 241, neither the piston 241 nor the valve rod 242 moves, and the valve rod 242 seals the air outlet 234. If the pressure of the liquid is greater than or equal to the threshold value, the liquid in the liquid storage cavity 2311 will squeeze the piston 241, and further drive the valve rod 242 to move, and finally open the air outlet 234. When the gas outlet 234 is opened, the gas supplied from the gas supply unit 210 enters the gas storage chamber 2312 through the gas inlet 233 and reaches the gas inlet 413 of the mixing assembly 40 through the gas outlet 234.

As an example, the second elastic member 243 may be a compression spring, but is not limited thereto.

As shown in fig. 10 to 12, fig. 10 is a cross-sectional view taken along B-B in fig. 1, in which an air source unit 280 is connected to the air intake joint 250. Fig. 11 shows a partial enlarged view at X2 in fig. 10. Fig. 12 shows a cross-sectional view along B-B in fig. 1, in which the air supply unit 280 is separated from the air inlet joint 250. The air source unit 280 includes an air outlet valve unit 260 and an air cylinder 270. The outlet valve unit 260 is detachably connected to the inlet joint 250. The gas cylinder 270 stores gas, and the gas cylinder 270 is connected to the gas outlet valve unit 260 and communicates with the gas inlet joint 250 through the gas outlet valve unit 260.

The air outlet valve unit 260 includes a second valve body 261 and a third opening and closing unit 262. The second valve body 261 is detachably connected with the air inlet joint 250, and the second valve body 261 has an air outlet channel 2611 communicating with the gas cylinder 270. The third opening and closing unit 262 is disposed in the air outlet channel 2611, and is used for opening and closing the air outlet channel 2611.

The third opening and closing unit 262 includes a second fixing member 2621, a second stopper 2622, and a third elastic member 2623. The second fixing member 2621 is fixedly disposed in the outlet channel 2611. The second plug 2622 is disposed in the outlet channel 2611 and is movable between a fifth position and a sixth position relative to the second fixture 2621. In the fifth position, the second plug 2622 and the second fixing member 2621 block the outlet flow channel 2611, and in the sixth position, the second plug 2622 is abutted by the inlet fitting 250 without blocking the outlet flow channel 2611. The third elastic member 2623 is disposed between the second stopper 2622 and the second fixing member 2621 for providing an elastic force to the second stopper 2622 toward the fifth position.

When the air source unit 280 is separated from the air inlet connector 250, the second plug 2622 is not pressed against the air inlet connector 250, so that the second plug 2622 is kept at the fifth position under the elastic force of the third elastic element 2623, and at this time, the air in the air storage bottle 270 cannot flow out of the air outlet channel 2611. When the air source unit 280 is mounted on the air inlet connector 250, a part of the air inlet connector 250 extends into the air outlet channel 2611 of the second valve body 261 and abuts against the second plug 2622 to move from the fifth position to the sixth position, and a channel through which air flows is formed between the second plug 2622 and the second fixing member 2621 during the movement of the second plug 2622, and the air in the air bottle 270 reaches the air outlet channel 2611 of the second valve body 261 through the channel.

The gas outlet valve unit 260 further comprises a gas path relief valve 263, and the gas path relief valve 263 is communicated between the gas cylinder 270 and the second valve body 261, for reducing the pressure of the gas supplied from the gas cylinder 270 to 3Bar.

As shown in fig. 13, fig. 13 is a flow chart of a gas path and a water path of the gas-liquid mixing device according to the first embodiment of the present utility model. After the second switch valve 60 is opened, a part of the liquid flows to the hand shower 50, and a part of the liquid flows to the linkage valve 220. When the pressure of the liquid flowing to the linkage valve 220 is greater than or equal to the threshold value, the air outlet 234 of the linkage valve 220 is opened, so that the air enters the mixing assembly 40 through the linkage valve 220 and is mixed with the liquid, and finally the carbonated spring is sprayed out by the hand-held shower 50.

As shown in fig. 14 to 16, fig. 14 is a schematic view showing a gas-liquid mixing apparatus according to a second embodiment of the present utility model. Fig. 15 shows a schematic view of the rear cover of fig. 14 with the housing omitted. Fig. 16 is a flow chart showing the gas path and the water path of the gas-liquid mixing device according to the second embodiment of the present utility model. The gas-liquid mixing device of the second embodiment is the same as that of the first embodiment, and is not described in detail, and the difference is that: the amount of gas supplied by the gas supply unit 210 is adjustable so that the concentration of the sprayed carbonated spring is adjustable to accommodate different demands of consumers.

Specifically, the gas supply unit 210 includes a first on-off valve 290, a first flow-through valve 291, and a second flow-through valve 292. The inlet of the first on-off valve 290 communicates with the gas circuit pressure reducing valve 263. An inlet of the first flow-through valve 291 selectively communicates with an outlet of the first on-off valve 290, and an outlet of the first flow-through valve 291 communicates with the air inlet 233 of the linkage valve 220. An inlet of the second flow valve 292 is selectively communicated with an outlet of the first switching valve 290, and an outlet of the second flow valve 292 is communicated with the air inlet 233 of the linkage valve 220. The first flow valve 291 is provided with a larger excess air than the second flow valve 292.

Since the excess air amount of the first flow valve 291 is larger than that of the second flow valve 292, the amount of air passing through the first flow valve 291 is larger than that of air passing through the second flow valve 292, and a larger amount of air can form a higher concentration of gas-liquid mixed water, and a lower amount of air can form a lower concentration of gas-liquid mixed water.

The first on-off valve 290 is a valve with an adjustable gear. The first switching valve 290 includes a gas cut-off gear, a high concentration gear, and a low concentration gear. When the first on-off valve 290 is in the off-range position, the first on-off valve 290 is not in communication with the first and second flow valves 291, 292. When the first on-off valve 290 is in the high concentration range, the first on-off valve 290 communicates with the first flow valve 291 and does not communicate with the second flow valve 292; when the first on-off valve 290 is in the low concentration range, the first on-off valve 290 communicates with the second flow valve 292 and does not communicate with the first flow valve 291.

In an embodiment of the present utility model, the first switching valve 290 includes an adjustment knob 293, and the gear of the first switching valve 290 is adjustable by operating the adjustment knob 293. When the first switching valve 290 is in the off-gas range, the adjustment knob 293 is horizontally disposed, and the gas supply unit 210 does not supply gas. When the first switching valve 290 is in the high-concentration range, the adjustment knob 293 swings upward, and the gas supply unit 210 supplies a large amount of gas. When the first switching valve 290 is in the low concentration range, the adjustment knob 293 swings downward, and the gas supply unit 210 supplies a small amount of gas.

It is understood that in the embodiment of the present utility model, the excess air amount of the first flow valve 291 and the excess air amount of the second flow valve 292 are both fixed values. When high-concentration gas-liquid mixture water is required, the first switching valve 290 is directly adjusted to a high-concentration gear. When low concentration gas-liquid mixture water is required, the first switch valve 290 is directly adjusted to the low concentration gear. The design that the air flow is the fixed value is more convenient for user operation, avoids the user to adjust inadequately and leads to mixing water concentration unsuitable. Further, the adjustment range of the first switching valve 290 is not limited to two, and may be, for example, a high-concentration range, a medium-concentration range, and a low-concentration range.

In another aspect of the utility model, a carbonated spring shower is provided, comprising a gas-liquid mixing device according to any of the embodiments described above. The carbonated spring shower according to the embodiments of the present utility model has all the advantages and benefits of any of the embodiments described above, and is not described here again.
