The frothing device 10 will be described below with reference to the drawings to illustrate the working principle of the frothing device 10.

Referring to fig. 2 and 3, the frothing device 10 includes a housing 100 and a frothing assembly 200, the housing 100 is a mounting body of the frothing device 10 and is used for loading the frothing assembly 200, and the frothing assembly 200 is capable of frothing a gas-liquid mixed fluid flowing through the housing 100 and generating sparkling water.

The housing 100 is provided with a water inlet passage 110 for the inflow of the gas-liquid mixture fluid and a water outlet passage 120 for the outflow of the gas-liquid mixture fluid, the water inlet passage 110 can divide the inflow gas-liquid mixture into at least two paths for outputting, specifically, the water inlet passage 110 includes a water inlet 111 and a gas-liquid outlet 112, the gas-liquid mixture fluid enters the water inlet passage 110 via the water inlet 111 and then leaves the water inlet passage 110 via the gas-liquid outlet 112, the number of the gas-liquid outlets 112 is at least two, for example, the number of the gas-liquid outlets 112 may be two, in other embodiments, the number of the gas-liquid outlets may also be three, four, and the like.

The number of the bubbling assemblies 200 is the same as the number of paths of the gas-liquid mixed fluid output by the water inlet channel 110, that is, the number of the gas-liquid outlets 112. In the embodiment where the number of the gas-liquid outlets 112 is two, the number of the bubbling assemblies 200 is also two, and the bubbling inlets 210 of the two groups of the bubbling assemblies 200 are respectively communicated with the corresponding gas-liquid outlets 112, and it should be noted that the bubbling inlets 210 are communicated with the gas-liquid outlets 112, which means that the bubbling inlets 210 are directly connected with the gas-liquid outlets 112, and the gas-liquid mixed fluid directly enters the bubbling inlets 210 from the gas-liquid outlets 112; the foaming inlet 210 is communicated with the gas-liquid outlet 112, and it can be understood that other parts are arranged between the foaming inlet 210 and the gas-liquid outlet 112, and the gas-liquid mixed fluid enters the other parts from the gas-liquid outlet 112 and then enters the foaming inlet 220 through the other parts. The frothing outlets 220 of the two sets of frothing assemblies 200 are both communicated with the water outlet channel 120, and the communication between the frothing outlets 220 and the water outlet channel 120 can refer to the communication between the frothing inlet 210 and the gas-liquid outlet 112, which is not described herein again.

In an embodiment, the multiple sets of bubbling assemblies 200 are arranged side by side in the housing 100, and the positions of the multiple sets of bubbling assemblies 200 for receiving the gas-liquid mixed fluid and outputting the bubbling water are arranged flush with the axial direction of the housing 100, that is, in the axial direction of the housing 100, the bubbling inlets 210 and the bubbling outlets 210 of the multiple sets of bubbling assemblies 200 are located at the same axial position on the housing 100. The time for the foaming components 200 arranged in parallel to receive the gas-liquid mixed fluid from the water inlet channel 110 is similar, and the time for the foaming components 200 to form bubble water is also similar, so that the pressure for each group of foaming components 200 to receive the gas-liquid mixed fluid is also similar to the pressure generated when the bubble water is output outwards, and the overall stability of the foaming device 10 is improved.

Referring to fig. 4, in one embodiment, the foaming device 10 includes the fluidic members 300, the fluidic members 300 are disposed between the foaming components 200 and the water inlet passage 110, and the number of the fluidic members 300 is the same as that of the foaming components 200. The fluidic member 300 and the frothing assembly 200 can be fixed relative to each other by a threaded connection, and specifically, a first threaded section (not shown) is provided on a side of the fluidic member 300 facing the frothing inlet 210, and a second threaded section (not shown) is provided on a side of the frothing assembly 200 facing the fluidic member 300, and the first threaded section and the second threaded section can be fixed in a threaded connection.

Specifically, the fluidic member 300 is provided with a fluidic channel 310 and a diffusion chamber 320 which are connected with each other, one end of the fluidic channel 310 is connected with the water inlet channel 110, the gas-liquid outlet 112 is connected with the fluidic channel 310, the other opposite end of the fluidic channel 310 is connected with the diffusion chamber 320, the side of the diffusion chamber 320, which faces away from the fluidic channel 310, is connected with the bubbling inlet 210, and the cross-sectional area of the fluidic channel 310 is smaller than the cross-sectional areas of the water inlet channel 110 and the diffusion chamber 320. The gas-liquid mixed fluid enters the jet piece 300 from the gas-liquid outlet 112, passes through the jet channel 310 and the diffusion chamber 320 in sequence, and finally enters the frothing assembly 200 from the diffusion chamber 320. Because the cross-sectional area of the jet flow channel 310 is smaller than that of the water inlet channel 110, the pressure of the gas-liquid mixed fluid entering the jet flow channel 310 from the gas-liquid outlet 112 is suddenly increased, so that the flow speed of the gas-liquid mixed fluid in the jet flow channel 310 is increased, the gas-liquid impact force is improved, and the subsequent generation of bubble water is facilitated. Since the cross-sectional area of the diffusion chamber 320 is larger than that of the jet flow channel 310, the pressure applied to the gas-liquid mixed fluid at the moment when the gas-liquid mixed fluid enters the diffusion chamber 320 from the jet flow channel 310 is suddenly reduced, so that a negative pressure is formed at the outlet of the jet flow channel 310, and the gas is further dissolved in the water.

In an embodiment, the frothing assembly 200 may include three bubblers 230, the three bubblers 230 are connected end to form the frothing assembly 200, the frothing assembly 200 may be relatively fixed to the plurality of bubblers 200 through a threaded connection, and a specific connection manner between the three bubblers 230 may refer to the threaded connection between the fluidic piece 300 and the frothing assembly 200, which is not described herein again. It is noted that the number of bubblers 230 may be the same between each set of bubbling assemblies 200, e.g., bubbling assemblies 200 each include three bubblers 230; the number of bubblers 230 in each set of bubbling assemblies 200 may also be varied, depending on the application, for example, three bubblers 230 in one set of bubbling assemblies 200 and four bubblers 230 in another set of bubbling assemblies 200.

In one embodiment, the bubbler 230 is provided with at least one bubbling channel 231, for example, the bubbler 230 may be provided with two bubbling channels 231, both of which are connected to the diffusion chamber 320, and both of the bubbling channels 231 may receive the gas-liquid mixed fluid from the diffusion chamber 320; the cross-sectional area of each of the bubbling channels 231 gradually increases from one side toward the gas-liquid outlet 112 to the opposite side. The bubbling channel 231 is provided with a cross-sectional area which is gradually increased to enlarge the gas-liquid mixing volume, and simultaneously, the pressure of gas-liquid mixed fluid flowing through the bubbling channel 231 is gradually reduced, gas dissolved in water bubbles in the bubbling channel 231, and a large amount of micro-nano bubbles are formed in the gas-liquid mixed fluid passing through the bubbling channel 231 in an instant manner by matching with high-speed impact gas of water flow. Furthermore, in use, the fluidic member 300 is above the bubbler 230 and, because the gas is less dense than the liquid, the gas tends to rise upward, the liquid tends to impinge downward, the high velocity water stream impinges on the gas, and the gas and liquid mix vigorously, creating a large volume of bubble water instantaneously. Preferably, the shape of the bubbling channel 231 may be a cone.

In an embodiment, the bubbler 230 further includes an expansion tank 232 connected to the bubbling channel 231, the expansion tank 232 is disposed at an end of the bubbling channel 231 close to the gas-liquid outlet 112, a cross-sectional area of the expansion tank 232 is larger than a cross-sectional area of the bubbling channel 231 close to an end surface of the gas-liquid outlet 112, and a side of the expansion tank 232 facing away from the bubbling channel 231 is communicated with the diffusion chamber 320. The arrangement of the expansion groove 232 can increase the gas-liquid mixing volume, and can also store partial gas which is not dissolved in water, so that more gas is contained in the cavity, and more bubbles are convenient to generate. After entering the expansion tank 232 from the diffusion chamber 320, the gas-liquid mixed fluid impacts the wall of the expansion tank 232, so that the gas and the liquid are mixed more vigorously, and the number of the nano microbubbles is increased.

In the foaming device 10, the number of the gas-liquid outlets 112 is set to be at least two, so that the gas-liquid mixed fluid flowing through the water inlet channel 110 can be divided into multiple paths of gas-liquid mixed fluids to flow to different foaming components 200, and the different foaming components 200 respectively foam the gas-liquid mixed fluid flowing in, thereby forming the bubble water; compare in a traditional a set of foaming subassembly 200 and bubble one way gas-liquid mixture fluid, the multiunit foaming subassembly 200 of this sparger 10 respectively bubbles multichannel gas-liquid mixture fluid and forms bubble water, and the multichannel bubble water converges into one way at last and goes out water through outlet channel 120, can carry out the foaming to more large-traffic gas-liquid mixture fluid under the condition that does not influence the foaming effect.

Referring to fig. 5, in an embodiment, the housing 100 is further provided with an air-liquid collecting chamber 130, and the air-liquid collecting chamber 130 can provide a collecting place for the bubble water generated by each set of the bubbling assembly 200. Specifically, the bubble water output by each group of bubbling assemblies 200 flows to the gas-liquid collecting cavity 130 to be collected, and the gas-liquid collecting cavity 130 is communicated with the water outlet channel 120. After the bubbling assemblies 200 generate the bubbling water, the bubbling water flows out from the bubbling outlets 220 to the gas-liquid collecting cavity 130 to be converged into a path of bubbling water, and finally, the path of bubbling water leaves the bubbling device 20 through the water outlet channel 120 to be output outwards.

Preferably, the water outlet direction of the gas-liquid mixed fluid in the frothing assembly 200 to the gas-liquid collecting cavity 130 is a first direction (the first direction may refer to an X direction in fig. 5), the direction of the bubble water in the gas-liquid collecting cavity 130 flowing to the water outlet channel 120 is a second direction (the second direction may refer to a Y direction in fig. 5), and an included angle between the first direction and the second direction is 180 degrees. So set up, bubble water just can carry out external output bubble water through exhalant canal 120 after occupying gas-liquid and collect chamber 130, can furthest's improvement bubble water collect the dwell time in chamber 130 at the gas-liquid to obtain the bubble of littleer volume.

The water outlet channel 120 includes a water outlet 121, and the bubble water exits the foaming device 20 through the water outlet 121 to be discharged. The relative positions of the water outlet 121 and the water inlet 111 on the housing 100 are different, and the arrangement of the water inlet passage 110 or/and the water outlet passage 120 needs to be changed accordingly. On the premise that the bubble water can be reserved in the gas-liquid collecting cavity 130, different relative positions of the water outlet 121 and the water inlet 111 can bring different technical effects to the foaming device 10. Two embodiments with different relative positions of the water outlet 121 and the water inlet 111 on the casing 100 will be chosen for description below, so as to describe what technical effect can be brought by different relative positions of the water outlet 121 and the water inlet 111 on the casing 100.

Example one

The water outlet 121 and the water inlet 111 are arranged on the same side of the shell 100, and the axial length of the water inlet channel 110 can be set to be a short channel, so that the resistance of the water inlet channel 110 to the gas-liquid mixed fluid can be reduced, the flow of the gas-liquid mixed fluid flowing through the water inlet channel 110 in unit time can be increased, and the water inlet channel 110 can provide the gas-liquid mixed fluid with a larger flow for the foaming assembly 200; the water inlet direction of the water inlet channel 110 is perpendicular to the water outlet direction of the water outlet channel 120, so that the axial length of the water inlet channel 110 can be shortened to the greatest extent, and the resistance of a pipeline to the gas-liquid mixed fluid can also be reduced, thereby being beneficial to increasing the flow of the gas-liquid mixed fluid flowing through the water inlet channel 110 in unit time, and further enabling the water inlet channel 110 to provide a larger flow of the gas-liquid mixed fluid for the foaming component 200.

In one embodiment, the water inlet channel 110 includes a multi-stage pressurizing channel 140, and the cross-sectional area of the multi-stage pressurizing channel 140 decreases along the water inlet direction of the water inlet 111. Because the cross-sectional area of the multi-section pressurizing channel 140 is gradually reduced along the water inlet direction of the water inlet 111, the pressure applied to the gas-liquid mixed fluid after passing through each section pressurizing channel 140 is gradually increased, so that the flow speed of the gas-liquid mixed fluid in the water inlet channel 110 can be further increased, the gas-liquid impact force is improved, and the subsequent generation of bubble water is facilitated. Preferably, the axial lengths of the multiple stages of pressurizing channels 140 are gradually increased along the water inlet direction of the water inlet 111, so as to maintain the flow rate of the gas-liquid mixed fluid passing through each stage of pressurizing channel 140 in a relatively equal state in unit time, which is beneficial to reducing the resistance of the whole water inlet channel 110 to the gas-liquid mixed fluid flowing through.

Specifically, the water inlet channel 110 may include a first pressurizing channel 141, a second pressurizing channel 142, a third pressurizing channel 143, and a fourth pressurizing channel 144, where the gas-liquid mixed fluid passes through the first pressurizing channel 141, the second pressurizing channel 142, the third pressurizing channel 143, and the fourth pressurizing channel 144 from the water inlet 111 in sequence, where a cross-sectional area of the first pressurizing channel 141 is larger than a cross-sectional area of the second pressurizing channel 142, a cross-sectional area of the second pressurizing channel 142 is larger than a cross-sectional area of the third pressurizing channel 143, and a cross-sectional area of the third pressurizing channel 143 is larger than a cross-sectional area of the fourth pressurizing channel 144; and the axial length of first boost passage 141 is less than the axial length of second boost passage 142, the axial length of second boost passage 142 is less than the axial length of third boost passage 143, and the axial length of third boost passage 143 is less than the axial length of fourth boost passage 144.

Example two

In order to keep bubble water remaining in the gas-liquid collecting chamber 130, when the water outlet 121 and the water inlet 111 are disposed at opposite sides of the housing 100, the water inlet passage 110 needs to extend to opposite ends of the housing 100. In addition, delivery port 121 and water inlet 111 locate casing 100 relative both ends can better adapt to specific application environment, for example, when installing under the kitchen, the hydraulic pipeline can directly be followed casing 100 below and water inlet 111 intercommunication, the bubble water can export the tap to the kitchen mesa through the delivery port 121 of top after accomplishing the bubbling, the elbow pipeline of additionally plugging into need not during the installation, can adopt the connecting line of vertical direction, it is more smooth and easy to make to connect between the pipeline, be convenient for install foaming device 20.

Referring to fig. 8, in an embodiment, the water inlet channel 110 includes a first channel 151 and a second channel 152 connected to each other, the first channel 151 extends from an end of the housing 100 facing away from the water outlet 121 of the water outlet channel 120 to an opposite end, the second channel 152 is disposed at an end of the water outlet 121 of the water outlet channel 120, and the second channel 152 is communicated with the foaming assembly 200. This embodiment is through setting up first passageway 151 to the passageway that extends to the relative both ends of casing 100 to can prolong inhalant canal 110's size, longer first passageway 151 can increase the gas-liquid mixture volume, can also partly not dissolve in the gas of water of storage, makes and holds more gas in the cavity, the follow-up more bubbles that produce of being convenient for.
