Description

Technical Field

[0001] The present application relates to a gas-liquid mixing device. Background Art

[0002] In the existing gas-liquid mixing process, such as in the preparation process of carbonated spring, the gas is not easy to completely dissolve into the liquid, resulting in low gas utilization, gas waste, and low gas mixing concentration in the mixed liquid.

[0003] Therefore, how to improve the gas utilization rate and gas mixing concentration in the gas-liquid mixing process is a technical problem that needs to be solved in the prior art. Summary of the invention

[0004] In response to the above problems, the present application discloses a gas-liquid mixing device, which can realize multiple gas-liquid mixing processes, and can realize the recovery and remixing process of unmixed gas. The overall structural design is ingenious, the space occupied is small, and the mixing effect is good.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0006] The present application provides a gas-liquid mixing device, which includes a gas-liquid mixing valve, a vortex generator and a gas recovery device along an arrangement direction. The gas-liquid mixing valve can be externally connected to a liquid supply device and a gas supply device respectively, and can deliver the mixed liquid flow after the received liquid and gas are mixed to the vortex generator. The vortex generator can divide the mixed liquid flow into multiple liquid flows, and can make each liquid flow rotate around a central axis set along the arrangement direction, and deliver each rotating liquid flow to the gas recovery device. The gas recovery device is formed with a gas recovery chamber and a cylindrical annular chamber surrounding the gas recovery chamber, and the gas recovery chamber has an air suction hole connected to the cylindrical annular chamber on the side close to the vortex generator, and the gas recovery chamber has a liquid through hole connected to the cylindrical annular chamber on the side away from the vortex generator. Each rotating liquid flow delivered by the vortex generator can flow in a spiral in the cylindrical annular cavity and enter the gas recovery cavity through the liquid through hole. The mixed liquid flow flowing in a spiral in the cylindrical annular cavity can generate negative pressure to suck the gas in the gas recovery cavity into the cylindrical annular cavity through the suction hole.

[0007] The above-mentioned gas-liquid mixing equipment can realize a secondary mixing process. The first mixing is mainly realized in the gas-liquid mixing valve, and the second mixing is mainly realized in the cylindrical annular cavity. It can realize the recovery and remixing process of unmixed gas. The overall structural design is ingenious, occupies little space, and has a good mixing effect.

[0008] In an illustrative embodiment of the gas-liquid mixing device, the gas recovery device includes a first guide body and a second guide body. The first guide body is a cylindrical structure, and the first guide body is hollow inside to form a gas recovery chamber, and the air suction hole and the liquid through hole are arranged on the first guide body. The second guide body can be covered on the first guide body, and there is a gap between the second guide body and the first guide body to form a cylindrical annular cavity. The above structure is easy to implement and easy to assemble.

[0009] In an illustrative embodiment of the gas-liquid mixing device, a recycling device is further provided in the gas recovery chamber. The recycling device is formed with an air intake channel and a mixed liquid channel surrounding the air intake channel. The recycling device is also formed with an air intake chamber connected with the air intake channel, and a liquid outlet is provided in the air intake chamber at a position opposite to the air intake channel. The recycling device is also formed with a guide chamber surrounding the air intake chamber, the guide chamber is connected with the mixed liquid channel, and the guide chamber is connected with the air intake chamber through several vortex channels. Several vortex channels are arranged around the axis of the air intake channel, and can make the liquid entering the air intake chamber through each vortex channel converge to form a vortex, so as to generate a negative pressure that can be inhaled from the air intake channel.

[0010] The recycling device can help to realize the second recycling of the gas to be mixed in the gas recovery chamber, further improve the gas utilization rate and improve the mixing effect.

[0011] In an exemplary embodiment of the gas-liquid mixing device, a liquid inlet gap communicating with the liquid through hole is provided between the recycling device and the inner wall of the gas recovery chamber, and the gas recovery chamber further comprises a gas storage space communicating with the air suction hole and the liquid inlet gap. The air suction channel is communicated with the gas storage space, and the mixed liquid can flow into the mixed liquid channel via the liquid through hole, the liquid inlet gap and the gas storage space.

[0012] In an exemplary embodiment of the gas-liquid mixing device, each vortex channel is centered on the axis of the air intake channel and is arranged along the trajectory of the Archimedean spiral.

[0013] In an exemplary embodiment of the gas-liquid mixing device, the mixed liquid channel is connected to the guide cavity through a plurality of guide holes, the plurality of guide holes are arranged around the axial direction of the air intake channel, and each guide hole is inclined toward a rotation direction around the axial direction, so that the flow direction of the liquid entering the guide cavity is changed and then introduced into a plurality of vortex channels. This structure makes it easier to ensure the rotation speed of the final vortex and increase the negative pressure effect.

[0014] In an exemplary embodiment of the gas-liquid mixing device, the recycling device includes a plurality of guide ribs for separating the air suction chamber and the guide chamber, the plurality of guide ribs are arranged axially around the air suction channel, and a vortex channel is formed between two adjacent guide ribs. The structure is simple and easy to design and process.

[0015] In an illustrative embodiment of a gas-liquid mixing device, a gas-liquid mixing valve includes a mixing valve body, a movable frame and a reset member. An accommodating chamber is formed in the mixing valve body, and the mixing valve body is provided with a liquid inlet channel, an air inlet channel and a liquid outlet channel connected to the accommodating chamber, and the liquid outlet channel is connected to the vortex generator. The movable frame can be movably arranged in the accommodating chamber to divide the accommodating chamber into a first mixing chamber and a second mixing chamber that can be connected to each other, the first mixing chamber is connected to the liquid inlet channel and the air inlet channel, and the second mixing chamber is connected to the liquid outlet channel, and the movable frame can be moved to a blocking position that blocks the connection between the first mixing chamber and the air inlet channel. The reset member can apply a restoring force to the movable frame to keep it in the blocking position. The pressure generated by the liquid entering the first mixing chamber through the liquid inlet channel can push the movable frame to overcome the restoring force and leave the blocking position.

[0016] The above structure can realize the linkage process of liquid supply and gas supply. During continuous use, it is only necessary to control the disconnection of the liquid supply in the liquid inlet channel. The mobile frame can be used to control the gas supply at the same time, which simplifies the structure and operation. The gas supply control is also stricter, which can effectively improve the utilization rate of the gas.

[0017] The above structure also allows the liquid to first enter the first mixing chamber divided by the accommodating chamber, so the liquid will contact the gas in a smaller space, and coupled with the effect of the liquid pressure, the liquid is more likely to have turbulence when entering the first mixing chamber, so that the gas increases the contact area with the liquid, and the mixing effect is improved. Then, the second mixing chamber is used to achieve secondary mixing, thereby improving the mixing effect.

[0018] In an illustrative embodiment of the gas-liquid mixing device, the mixing valve body also includes a water inlet and air inlet frame and a mixing chamber frame. The liquid inlet channel and the air inlet channel are opened on the water inlet and air inlet frame. The mixing chamber frame can be assembled on the water inlet and air inlet frame, and form a containing chamber with the water inlet and air inlet frame. The liquid outlet channel is arranged on the mixing chamber frame, and the mixing chamber frame also has a movable channel extending toward one side of the water inlet and air inlet frame. The movable frame can move along the movable channel, and fit with the inner wall of the movable channel to separate the first mixing chamber and the second mixing chamber. The inner wall of the movable channel is also formed with a liquid passage. The movable frame can also move to a conducting position corresponding to the liquid passage, and the liquid passage can connect the first mixing chamber and the second mixing chamber on both sides of the movable frame at the conducting position.

[0019] The above structure can also ensure a good gas-liquid mixing effect in the initial stage of linkage. The liquid flow direction can be changed through the liquid passage, and the liquid turbulence area can be increased, which is more helpful to disperse the gas, increase the contact area between the gas and the liquid, and improve the overall gas-liquid mixing effect.

[0020] In an exemplary embodiment of the gas-liquid mixing device, the vortex generator is formed with a main channel and a plurality of spiral channels connected to the main channel, the main channel is arranged along an arrangement direction, and each spiral channel extends outward along a spiral trajectory with the main channel as the center.

[0021] In an exemplary embodiment of the gas-liquid mixing device, the spiral channel extends outward along a planar spiral trajectory with the axial direction of the main channel as the center. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0067] In this document, “exemplary” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “exemplary” should not be interpreted as a more preferred or more advantageous technical solution.

[0068] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked.

[0069] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0070] Figure 1 A schematic diagram of an exploded structure for illustrating an exemplary embodiment of a gas-liquid mixing device. Figure 2 A schematic diagram of a combined three-dimensional structure for illustrating a schematic implementation of a gas-liquid mixing device.

[0071] The gas-liquid mixing equipment can realize the preparation process of mixing gas in liquid, such as mixing carbon dioxide into water to prepare carbonated spring. Of course, those skilled in the art will understand that in addition to mixing carbon dioxide into water, the gas-liquid mixing equipment can also be used to mix other gases and liquids.

[0072] like Figure 1 and Figure 2 As shown, the gas-liquid mixing device can be assembled and arranged along the direction indicated by the double-headed arrow in the figure. The assembled gas-liquid mixing device includes a gas-liquid mixing valve 10, a vortex generator 20 and a gas recovery device 30 in the arrangement direction (see Figure 2 ).

[0073] Among them, the gas-liquid mixing valve 10 can be connected to an external liquid supply device and a gas supply device. In the embodiment shown in the figure, the gas-liquid mixing valve 10 has a liquid inlet channel 121 for an external liquid supply device (not shown in the figure), and an air inlet channel 123 for an external gas supply device (not shown in the figure). The gas-liquid mixing valve can deliver the mixed liquid flow after the received liquid and gas are mixed to the vortex generator 20, that is, the main process of the first gas-liquid mixing is completed in the gas-liquid mixing valve. In the embodiment shown in the figure, the gas-liquid mixing valve 10 has a liquid outlet channel 124, and the gas-liquid mixing valve 10 can deliver the mixed liquid flow to the vortex generator 20 through the liquid outlet channel 124.

[0074] The vortex generator 20 can divide the mixed liquid flow delivered by the gas-liquid mixing valve 10 into multiple liquid flows, and can make each liquid flow rotate around a central axis extending along the arrangement direction in the figure, and deliver the rotating liquid flow to the gas recovery device 30.

[0075] exist Figure 1 and Figure 2 In the embodiment shown, the vortex generator 20 is formed with a main channel 22 and a plurality of spiral channels 24 connected to the main channel 22. The main channel 22 is arranged along the arrangement direction. Figure 3 , Figure 3 yes Figure 1 The schematic diagram of the structure of the vortex generator 20 in the A direction is as follows: Figure 3 As shown, each spiral channel 24 extends outwardly along a spiral trajectory with the main channel 22 as the center. In one embodiment, the spiral channel 24 extends outwardly along a plane spiral trajectory with the axis of the main channel 22 as the center. The mixed liquid flow delivered from the gas-liquid mixing valve 10 first enters the main channel 22, and is divided into multiple liquid flows through the multiple spiral channels 24. After each liquid flow flows along the spiral channel 24, it can rotate around the central axis of the main channel 22, and finally flows out of the spiral channel 24 and is delivered to the gas recovery device 30.

[0076] exist Figure 1 and Figure 2 In the embodiment shown, the gas recovery device 30 is composed of two parts, namely a cylindrical first guide body 32 and a second guide body 34 covered outside the first guide body 32. Figure 2 In order to clearly express the structural relationship after the combination, the second guide body 34 is represented by a dotted line. The first guide body 32 is hollow inside and has a gas recovery chamber 35. Figure 4 , Figure 4 The cross-sectional structure of an embodiment of the first flow guide 32 is shown. Figure 2 As shown, the gap between the first flow guide 32 and the second flow guide 34 forms a cylindrical annular cavity 33 , and the cylindrical annular cavity 33 surrounds the gas recovery cavity 35 .

[0077] The gas recovery chamber 35 has an air intake hole 332 (located in the first body guide 32) connected to the cylindrical annular chamber 33 on one side close to the vortex generator 20, and a liquid through hole 335 connected to the cylindrical annular chamber 33 on the other side of the gas recovery chamber 35 away from the vortex generator 20. The multiple rotating liquid flows delivered by the vortex generator 20 will flow spirally along the cylindrical annular chamber 33 respectively. Figure 2 The dotted line in the figure shows the spiral rotation trajectory of a rotating liquid flow. According to Bernoulli's principle, the spiral water flow will generate negative pressure when flowing in the cylindrical annular cavity 22. The negative pressure is the largest on the side close to the vortex generator 20. Therefore, the negative pressure will cause the gas in the gas recovery cavity 35 to flow to the cylindrical annular cavity 33 through the suction hole 322. After the multiple rotating liquid flows finally flow to the side of the cylindrical annular cavity 33 away from the vortex generator 20, they will enter the gas recovery cavity 35 through the liquid through hole 335.

[0078] In the actual working process, part of the gas to be mixed that is not mixed with the liquid will enter the gas recovery chamber 35 through the liquid hole 335, and the mixed liquid entering the gas recovery chamber 35 may also be unstable in the mixing state, causing the mixed liquid to separate from the gas into the gas recovery chamber 35, so that the gas recovery chamber has the gas to be mixed, and the gas to be mixed will rise to the top of the gas recovery chamber, that is, the side close to the vortex generator 20. At this time, the negative pressure formed by the spiral water flow in the cylindrical annular chamber 22 will suck the gas inside the gas recovery chamber 35 back to the cylindrical annular chamber 22 and achieve gas-liquid mixing with the spiral water flow, completing the main process of the second gas-liquid mixing, which is mainly a process of recovering and remixing the gas that was not completely mixed during the mixing process, thereby improving the gas utilization rate.

[0079] The above-mentioned gas-liquid mixing equipment can realize a secondary mixing process. The first mixing is mainly realized in the gas-liquid mixing valve 10, and the second mixing is mainly realized in the cylindrical annular cavity 22. It can realize the recovery and remixing process of unmixed gas. The overall structural design is ingenious, occupies little space, and has a good mixing effect.

[0080] Those skilled in the art will understand that Figure 1 and Figure 2 In the embodiment shown in the figure, the first flow guide 32 and the second flow guide 34 are arranged to form the gas recovery chamber 35, the cylindrical annular chamber 33, the air suction hole 332 and the liquid through hole 332 in the technical solution. This method can make the overall structure design and assembly convenient. The above-mentioned gas recovery chamber 35, the cylindrical annular chamber 33, the air suction hole 332 and the liquid through hole 332 are all spatial structures. According to different design requirements, any physical structure can be used to combine to form the above-mentioned spatial structure. The specific physical structure is not limited to Figure 1 and Figure 2 shown.

[0081] On the basis of the above-mentioned embodiment, the gas-liquid mixing device can also be provided with a recycling device 50, such as Figure 4 As shown in the figure, the third gas-liquid mixing process is realized, further improving the utilization rate of gas. Figure 4 As shown, a liquid inlet gap 352 communicating with the liquid through hole 335 is provided between the recycling device 50 and the inner wall of the gas recovery chamber 35 , and the gas recovery chamber 35 further has a gas storage space 353 communicating with the air suction hole 332 and the liquid inlet gap 352 .

[0082] The recycling device 50 is formed with an air intake channel 52 and a mixed liquid channel 54 surrounding the air intake channel 52. The air intake channel 52 is connected to the gas storage space 353, and the mixed liquid can flow into the mixed liquid channel 54 through the liquid hole 335, the liquid inlet gap 352 and the gas storage space 353.

[0083] The recycling device further forms an air suction cavity 56 connected to the air suction channel 52, and a liquid outlet 562 is arranged in the air suction cavity 56 at a position opposite to the air suction channel 52. The recycling device further forms a guide cavity 58 surrounding the air suction cavity 56, and the guide cavity 58 is connected to the mixed liquid channel 54.

[0084] In addition, the guide cavity 58 is connected to the air suction cavity 56 through a plurality of vortex channels 57. Figure 4 The eddy current channel 57 cannot be displayed in FIG. The setting scheme of the eddy current channel 57 can be seen in FIG. Figure 5 , Figure 5 It is a schematic diagram of the structure of the air suction chamber, flow guide chamber and vortex channel of the recycling device, such as Figure 5 As shown in the figure, the middle position is the air suction cavity 56, and a guide cavity 58 is arranged around the air suction cavity 56. The guide cavity 58 and the air suction cavity 56 can be connected through four vortex channels 57. The four vortex channels 57 are arranged axially around the air suction channel 52. Figure 4 and Figure 5 As shown, after the liquid flows from the mixed liquid channel 54 to the guide cavity 58 under a certain internal pressure, the above structure can make the liquid in the guide cavity 58 flow along the Figure 5 As shown by the dotted arrow in the middle, the liquid flows toward the suction chamber 56 through the vortex channel 57, and can make the liquid entering the suction chamber 56 through each vortex channel 57 converge to form a vortex. The vortex will cause a negative pressure to form in the central area of ​​the suction chamber 56. The negative pressure will be sucked into the suction chamber 56 from the gas recovery chamber 35 through the suction channel 52, and achieve gas-liquid mixing with the liquid in the suction chamber 56.

[0085] It should be noted that the vortex of the suction chamber 56 not only generates negative pressure to achieve the suction effect, but the vortex itself also prompts the gas entering the suction chamber 56 to mix with the liquid faster, so that the gas can contact and mix with the liquid more fully and quickly.

[0086] Therefore, the recycling device 50 can help to recycle the gas to be mixed in the gas recycling chamber 35, further improve the gas utilization rate, and improve the mixing effect.

[0087] In one embodiment, each vortex channel 57 in the recycling device 50 can be centered on the axis of the air intake channel 52 and arranged along the trajectory of the Archimedean spiral.

[0088] exist Figure 4 and Figure 5 In the illustrated embodiment, the mixed liquid channel 54 is connected to the guide cavity 58 through a plurality of guide holes 548. The plurality of guide holes 548 are arranged axially around the air intake channel 52, and each guide hole 548 is oriented in a rotation direction around the axial direction ( Figure 5 The vortex channels 57 are preferably arranged to be inclined in a clockwise direction so that the flow direction of the liquid entering the guide chamber 58 is changed, and the liquid flows in the guide chamber 58 along the direction of rotation and is finally introduced into each vortex channel 57. This structure makes it easier to ensure the rotation speed of the final vortex and increase the negative pressure effect.

[0089] In addition, Figure 5 In the illustrated embodiment, the recycling device 50 further includes a plurality of guide ribs 59 for separating the air intake chamber 56 and the guide chamber 58. The plurality of guide ribs 59 are arranged axially around the air intake passage 52, and a vortex passage 57 is formed between two adjacent guide ribs 59. The structure is simple and easy to design and process, but those skilled in the art can understand that the vortex passage 57 can also be formed by other structures or forms, and is not limited to the form of the guide ribs 59.

[0090] Figure 6 A schematic cross-sectional view of a gas-liquid mixing valve for illustrating a schematic embodiment of a gas-liquid mixing device. Figure 6 As shown, the gas-liquid mixing valve 10 includes a mixing valve body 12 , a moving frame 14 and a reset member 16 .

[0091] The mixing valve body 12 has a receiving chamber 122 formed therein, and is further provided with a liquid inlet channel 121 , an air inlet channel 123 and a liquid outlet channel 124 communicating with the receiving chamber 122 . The liquid outlet channel 124 is communicated with the vortex generator 20 .

[0092] Figure 6 In the embodiment shown, the mixing valve body 12 is composed of two parts, namely, the water inlet and air inlet frame 11 and the mixing chamber frame 13. The water inlet and air inlet frame 11 and the mixing chamber frame 13 together form the above-mentioned accommodating chamber 122, which will be described in detail later. Of course, those skilled in the art can understand that according to different design requirements, the mixing valve body 10 can also adopt other structures and other combinations, not limited to those shown in the figure.

[0093] See also Figure 6 The mobile rack 14 can be movably arranged in the accommodating chamber 122. The moving direction of the mobile rack 14 in the figure is along the vertical direction in the figure. It can be seen from the figure that the mobile rack 14 can divide the accommodating chamber 122 into a first mixing chamber 125 and a second mixing chamber 126 that can be connected to each other. It can be understood that the volume sizes of the first mixing chamber 125 and the second mixing chamber 126 will change accordingly with the movement of the mobile rack 14.

[0094] See also Figure 6 The first mixing chamber 125 is connected to the liquid inlet channel 121 without obstruction, and whether the first mixing chamber 125 is connected to the air inlet channel 123 is determined by the moving position of the moving frame 14. Figure 3 In the figure, the movable frame 14 just moves to the blocking position that blocks the connection between the first mixing chamber 125 and the air intake channel 123. In this position, the first mixing chamber 125 and the air intake channel 123 are not connected. When the movable frame 14 leaves the current blocking position, the first mixing chamber 125 and the air intake channel 123 can be connected, which will be described in detail later.

[0095] The reset member 16 can generally be an elastic member such as a spring, and the reset member 16 can apply a restoring force to the movable frame 14 to keep the movable frame 14 in the above-mentioned blocking position. After the liquid is injected into the first mixing chamber through the liquid inlet channel 121, when the pressure inside the first mixing chamber reaches a certain value, the restoring force (such as elastic deformation force) of the reset member 16 can be overcome to push the movable frame 14 to leave the first mixing chamber. Figure 3 The blocking position in .

[0096] Figures 7 to 9 A schematic diagram is used to illustrate the working process of a gas-liquid mixing valve. Figures 7 to 9 To illustrate the working process of the gas-liquid mixing valve.

[0097] like Figure 7 As shown, when in use, a gas supply device (not shown in the figure) connected to the air inlet channel 123 of the gas-liquid mixing valve can always supply gas to the air inlet channel 123, and the air inlet device is, for example, a gas tank. At this time, although the air inlet channel 123 continues to supply gas, the gas supply pressure F1 is less than the restoring force F2 of the reset member 16, that is, the movable frame 14 will be kept in the blocking position of blocking the connection between the air inlet channel 123 and the first mixing chamber 125 under the action of the restoring force of the reset member 16, so that the gas in the air inlet channel 123 cannot enter the first mixing chamber 125. The blocking of the air inlet channel 123 by the movable frame 14 can be achieved by providing a corresponding rubber plug structure on the movable frame 14.

[0098] When mixing is ready to start, liquid is supplied to the first mixing chamber 125 through the liquid supply device (not shown in the figure) from the liquid inlet channel 121. The liquid supply pressure must be greater than the restoring force F2 of the reset member. The first mixing chamber 125 will then be filled with liquid and the internal pressure will increase until the pressure inside the first mixing chamber 125 can overcome the restoring force F2 of the reset member, so as to push the movable frame 14 to leave the blocking position and move downward in the vertical direction in the figure, as shown in FIG. Figure 8 As shown, at this time, the gas in the air inlet channel 123 enters the first mixing chamber 125 and mixes with the liquid in the first mixing chamber 125 .

[0099] As described above, after adopting the above structure, the air inlet channel 123 can continuously supply air, but only after the liquid inlet channel 121 supplies liquid into the first mixing chamber 125 and pushes the movable frame 14, the gas in the air inlet channel 123 will immediately enter the first mixing chamber 125. The above structure can realize the linkage process of liquid supply and gas supply. During continuous use, it is only necessary to control the disconnection of liquid supply in the liquid inlet channel 121, and the movable frame 14 can be used to realize the control of gas supply at the same time, simplifying the structure and operation, and making the gas supply control more stringent. Gas will be supplied only when liquid enters, which can effectively improve the utilization rate of gas.

[0100] It should also be noted that because the movable frame 14 divides the accommodating chamber 122 into a first mixing chamber 125 and a second mixing chamber 126, the liquid cannot completely fill the accommodating chamber 122 at once, but enters and flows out in a sequence, which prolongs the gas-liquid mixing time. This sequence is very helpful for the gas-liquid mixing process. Figure 8 As shown, the liquid first enters the first mixing chamber 125, and then Fig. 9 As shown, the liquid will then enter the second mixing chamber 126, and finally flow out from the liquid outlet channel 124 to the vortex generator 20 (see Figure 1 and Figure 2 ).

[0101] Compared with the entire accommodating chamber 122, the liquid will first enter the smaller space (the first mixing chamber 125) divided in the accommodating chamber 122, so the liquid will contact the gas in a smaller space. In addition, due to the effect of the liquid pressure, the liquid is more likely to have turbulence when entering the first mixing chamber 125. The turbulence will intensify the dispersion of the gas, increase the contact area between the gas and the liquid, and improve the mixing effect. Then the liquid will carry the gas into the second mixing chamber to achieve secondary mixing.

[0102] Therefore, the gas-liquid mixing valve makes full use of the mixing space where the liquid and the gas just come into contact, which can greatly improve the gas-liquid mixing effect.

[0103] exist Figures 6 to 9In the illustrated embodiment, the mixing valve body 10 is composed of two parts, namely, a water inlet and air inlet frame 11 and a mixing chamber frame 13. Among them, the liquid inlet channel 121 and the air inlet channel 123 are opened on the water inlet and air inlet frame 11. The mixing chamber frame 13 can be assembled on the water inlet and air inlet frame 11, and together with the water inlet and air inlet frame 11, it forms a receiving chamber 122. The liquid outlet channel 124 is provided on the mixing chamber frame 13.

[0104] like Figures 6 to 9 As shown, the mixing chamber frame 13 also has a moving channel 132 extending toward one side of the water inlet and air inlet frame 11. After the mixing chamber frame 13 and the water inlet and air inlet frame 11 enclose the accommodating chamber 13, the moving channel 132 will be located in the accommodating chamber 13. The moving frame 14 can move along the moving channel 132, and the moving frame 14 is configured to be able to fit with the inner wall of the moving channel 132 to separate the first mixing chamber 125 and the second mixing chamber 126.

[0105] like Figures 6 to 9 As shown, a liquid passage 1322 is also formed on the inner wall of the moving channel 132 of the mixing chamber frame 13, and the moving frame 14 can move relative to the moving channel 132 to a conducting position corresponding to the liquid passage 1322, as shown in FIG. Fig. 9 As shown, in this position, the liquid passage 1322 can connect the first mixing chamber 125 and the second mixing chamber 126 on both sides of the movable frame 14 at the conducting position, so that the liquid in the first mixing chamber 125 is transferred to the second mixing chamber 126.

[0106] The above structure can also ensure a good gas-liquid mixing effect in the initial stage of linkage. As mentioned above, in the initial stage of linkage, liquid is supplied to the first mixing chamber 125 through the liquid inlet channel 121. Before the internal pressure of the first mixing chamber 125 reaches a level that can overcome the reset force of the reset member 16, the air inlet channel 123 is not yet connected, and the gas and liquid are not mixed. At this time, because the inner wall of the movable frame 14 and the movable channel 132 fit each other, the liquid of the unmixed gas in the first mixing chamber 125 can be reduced or even prevented from entering the second mixing chamber 126. As the movable frame 14 moves away from its blocking position, the gas enters the first mixing chamber 125 through the air inlet channel 123, and the gas-liquid mixing in the first mixing chamber 125 is achieved. Figure 8 As shown, at this time, because the movable frame 14 has not moved to the conducting position, the liquid will stay in the first mixing chamber 125 as much as possible and fully mix with the gas in this process until the movable frame 14 moves to Fig. 9 In the conducting position shown, the first mixing chamber 125 and the second mixing chamber 126 are connected through the liquid passage 1322, and the gas and liquid enter the second mixing chamber 126 to complete the secondary mixing.

[0107] It should also be noted that since the liquid passage 1322 is opened on the inner wall of the movable passage 132, it can change the flow direction of the liquid, increase the liquid turbulence area, and help to disperse the gas, increase the contact area between the gas and the liquid, and improve the overall gas-liquid mixing effect.

[0108] In the embodiment shown in the figure, the liquid channel 1322 is a liquid hole opened on the side wall of the movable channel 132. Those skilled in the art can understand that according to different design requirements, the liquid channel 1322 can be arranged in more ways and is not limited to that shown in the figure. For example, the liquid channel 1322 can also be designed with a groove structure, etc.

[0109] The gas-liquid mixing device of the present application can be a carbonated spring generating device, which can be connected to bathtubs, faucets, showers and other equipment. Carbonated springs have many benefits for the human body: they can improve blood vessel function and reduce blood viscosity; improve blood circulation, reduce blood sugar and urine sugar; relieve bedsores and peripheral circulation disorders; improve symptoms such as autonomic nervous system disorders caused by stress and other factors, and regulate the balance of sympathetic and parasympathetic nerves; improve athletic performance; have the ability to repair damaged skin and hair; and have a strong ability to remove dirt and clean the body surface.

[0110] The above is only a specific implementation of the present application. Under the above teachings of the present application, those skilled in the art can make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above specific description is only to better explain the purpose of the present application, and the protection scope of the present application shall be based on the protection scope of the claims.
