Description

Technical Field

[0001] This utility model relates to the field of water purifiers, and in particular to a bubble water generating device and a water purifier including the same. Background Technology

[0002] One existing technology for generating micro / nano bubble water utilizes a jet injector, a mixing chamber, and a bubbler.

[0003] Conventional jet injector: Venturi structure, which generates negative pressure to draw in air by changing the diameter of the flow shaft of the Venturi tube. Then, when the water-air mixture is ejected from the nozzle, it generates high-frequency pressure fluctuations and high-speed, strong shearing forces, which shear the drawn-in gas into small bubbles.

[0004] Mixing chamber: Sheared air bubbles mix with water better;

[0005] Aerator: It is equipped with a filter screen and a microporous structure. The microporous structure achieves violent collision of water flow through the change of the flow cross section, forming a vortex that cuts the bubbles; at the same time, the micropores on the filter screen also cut the bubbles as they pass through, ultimately forming micro-nano bubbles.

[0006] Among them, such as Figure 1 As shown, the technical solution using an ejector, mixing chamber, and bubbler typically consists of three independent components, resulting in a relatively large overall volume. Because existing technologies only utilize a Venturi structure for bubble cutting, the turbulence and shear force distribution of the fluid are often uneven, leading to some bubbles not being fully broken up and potentially even bubble coalescing. Furthermore, existing technologies do not perform further bubble processing before entering the mixing chamber, resulting in poor final bubble shearing performance; some sheared bubbles are quite large and do not meet user requirements. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of existing bubble generating devices, which are large in size and have poor bubble shearing effect, and to provide a bubble water generating device and a water purifier including the same.

[0008] The present invention solves the above-mentioned technical problems through the following technical solution:

[0009] A bubble water generating device is provided, comprising a jet section, a mixing chamber, and a bubble cutting section. The jet section has a venturi structure. The bubble water generating device includes a housing with an internal accommodating space. The jet section, the mixing chamber, and the bubble cutting section are all disposed within the accommodating space. An inlet and an outlet are respectively connected to both ends of the housing. The jet section is connected to the inlet. The mixing chamber is connected to the jet section via a connecting pipe. The mixing chamber is connected to the outlet.

[0010] A bubble-cutting section is provided between the jet section and the mixing chamber, and / or between the mixing chamber and the outlet, for shearing bubbles generated in the water flow.

[0011] In this design, a Venturi structure is incorporated, generating pressure changes within the jet section to create shear force. This shear force cuts the incoming airflow, initially breaking it down into bubbles, thus merging the water and air to produce bubble water. By housing the jet section, mixing chamber, and bubble-cutting section within the same casing, the volume of the bubble water generator is reduced, improving space utilization. Specifically, bubble-cutting sections are located between the jet section and the mixing chamber, and between the mixing chamber and the outlet. These sections perform secondary cutting on bubbles that were not fully sheared or coalesced within the Venturi structure, further enhancing the bubble shearing effect and resulting in finer, more uniform bubbles in the final bubble water, ultimately forming micro-nano bubbles.

[0012] Preferably, the jet section includes a flow restrictor, a jet component, and an air inlet channel. The flow restrictor is connected to the water inlet and the jet component, respectively, and the air inlet channel is connected to the end of the jet component near the flow restrictor.

[0013] The jetting element is a Venturi structure.

[0014] In this design, a flow restrictor is used to control the flow rate of water entering the jet nozzle, ensuring a more uniform water flow and a stable ratio of water to airflow. This prevents excessive fluctuations in the water-to-bubble ratio, which negatively impacts the user experience. Simultaneously, an air intake channel is positioned between the flow restrictor and the jet nozzle. Utilizing Bernoulli's principle, external gas enters the jet section through this channel and merges with the water flow into the jet nozzle. This eliminates the need for a pressurization device like an air pump, simplifying the structure. The jet nozzle itself features a Venturi structure, which alters the internal pressure after the water and airflow enter, allowing for thorough mixing and the formation of bubble-filled water.

[0015] Preferably, the flow restrictor has at least a portion of its inner diameter smaller than that of the water inlet.

[0016] In this solution, the above settings can reduce the flow rate of water after it passes through the flow restrictor, improve the stability of the water flow entering the jet component, and ensure that the water and air flow enter evenly, avoiding excessive changes in water flow that could lead to an uneven ratio of water and air flow. At the same time, it can also change the flow rate of the water, allowing the water to enter the jet component more quickly and generating a larger pressure change, which in turn allows the air flow to be drawn into the jet component through the air intake channel.

[0017] Preferably, the flow restrictor includes a first channel and a second channel, the two ends of the first channel are respectively connected to the inlet and the second channel, the inner diameter of the first channel gradually decreases along the water flow direction, the two ends of the second channel are respectively connected to the first channel and the jetting device, and the inner diameter of the second channel is smaller than the inner diameter of the first channel;

[0018] At least a portion of the inner diameter of the first channel is smaller than the inner diameter of the inlet.

[0019] In this scheme, the diameter of the first channel gradually decreases, causing the water flow rate to gradually decrease. The diameter of the second channel is smaller than that of the first channel and remains unchanged, causing the water flow to gradually stabilize and controlling the flow velocity. This ensures that both the flow rate and flow velocity are relatively stable when the water flows out of the flow limiting device.

[0020] Preferably, the inner diameter of the jetting element gradually increases along the direction of water flow;

[0021] The inner wall surface of the jet component is provided with multiple protrusion structures;

[0022] The protruding structures are spaced apart along the axial direction of the jet component;

[0023] And / or, a plurality of the protruding structures are spaced apart circumferentially along the inner wall surface.

[0024] In this design, the Venturi structure generates negative pressure by changing the pipe diameter to draw in air. When the water-air mixture enters the jet inlet, it generates high-frequency pressure fluctuations and high-speed, strong shearing forces, shearing the drawn-in gas into small bubbles. A raised structure is designed as a vortex point, causing the passing water-air mixture to collide violently with the raised structure, forming vortices that further cut the bubbles.

[0025] Preferably, along the direction of water flow, the distance between two adjacent protrusions gradually increases;

[0026] And / or, along the direction of water flow, the radial dimension of the protrusion gradually increases.

[0027] In this scheme, the above settings can create a certain gradient change, better disrupting the fluid flow and causing the bubble water to generate more eddies and velocity changes, thereby increasing the degree of fluid turbulence. The enhanced turbulence makes the relative motion between the gas and liquid phases more intense, and the bubbles experience greater shear forces in the turbulence, making them more likely to break into smaller bubbles, resulting in more thorough cutting and effectively improving the cutting effect.

[0028] Preferably, the bubble cutting section includes a first bubble cutting element, which is disposed between the jet section and the mixing chamber;

[0029] The first bubble cutter includes a first filter screen and a second filter screen. Along the water flow direction, the first filter screen and the second filter screen are spaced apart, and the mesh number of the first filter screen is smaller than that of the second filter screen.

[0030] In this design, a first bubble cutter is placed between the jet section and the mixing chamber to shear the bubble-water mixture after it passes through the jet section, making the bubbles finer and improving their mixing with water. Specifically, a first filter screen cuts the bubbles; a second filter screen is spaced apart to buffer the relatively turbulent water-air mixture after passing through the jet and the first filter screen. The sheared bubbles are then slightly mixed and passed through the second filter screen at a slower flow rate, undergoing further shearing to achieve even finer bubbles. The mesh size of the second filter screen is smaller than that of the first filter screen, resulting in a better and finer bubble cutting effect.

[0031] Preferably, a baffle is provided inside the housing, and the periphery of the baffle is connected to the inner wall of the housing to separate the jet section and the mixing chamber; the mixing chamber and the jet component are connected only through the connecting channel, and a pump body is provided on the connecting channel.

[0032] In this design, a baffle separates the jet section and the mixing chamber, allowing both sections to be housed within the casing without interfering with each other. The jet section and the mixing chamber are connected only by a connecting channel. A pump is installed on the connecting channel to increase the water flow velocity, enabling the water to quickly enter the mixing chamber, resulting in intense water collisions and the formation of vortices, thus ensuring thorough mixing of the air bubbles and water.

[0033] Preferably, the bubble cutting section includes a second bubble cutting component, which is disposed between the mixing chamber and the water outlet;

[0034] The second bubble cutter includes a third filter screen, a fourth filter screen, and a through hole. The air mixing chamber and the water outlet are connected through the through hole, and the inner diameter of the through hole gradually decreases along the water flow direction.

[0035] The third filter and the fourth filter are respectively disposed at both ends of the through hole.

[0036] In this design, the through-hole structure of the second bubble cutter achieves intense water flow collisions through changes in the flow cross-section, forming eddies that cut the bubbles. Simultaneously, a third and fourth filter screen are respectively installed at both ends of the through-hole, further cutting the bubbles as they pass through, ultimately forming micro-nano bubbles.

[0037] A water purifier is provided, including the bubble water generating device as described above.

[0038] The significant advantages of this invention are as follows: By incorporating a Venturi structure within the bubble water generator, pressure changes within the jet section generate shear force, which shears the incoming airflow, initially breaking it down into bubbles. This achieves the fusion of water and airflow, producing bubble water. By housing the jet section, mixing chamber, and bubble-cutting section within the same casing, the size of the bubble water generator is reduced, improving space utilization. Specifically, the bubble-cutting section, located between the jet section and the mixing chamber, and between the mixing chamber and the outlet, performs secondary cutting on bubbles that were not sufficiently sheared or coalesced within the Venturi structure. This secondary cutting further enhances the bubble shearing effect, resulting in finer and more uniform bubbles in the final bubble water, ultimately forming micro-nano bubbles.

[0071] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment as an example.

[0072] Example 1

[0073] In this embodiment, a bubble water generating device is provided, such as... Figure 2-3 As shown, the device includes a jet section 1, a mixing chamber 2, and a bubble cutting section 3. The jet section 1 has a venturi structure. The bubble water generating device includes a housing 4, which has an internal space. The jet section 1, the mixing chamber 2, and the bubble cutting section 3 are all located inside the internal space. The two ends of the housing 4 are respectively connected to an inlet and an outlet 42. The jet section 1 is connected to the inlet. The mixing chamber 2 is connected to the jet section 1 through a connecting pipe. The mixing chamber 2 is connected to the outlet 42.

[0074] The bubble cutting section 3 has three configuration methods: First, it is set between the jet section 1 and the mixing chamber 2; second, it is set between the mixing chamber 2 and the outlet 42; third, the bubble cutting section 3 is set both between the jet section 1 and the mixing chamber 2 and between the mixing chamber 2 and the outlet 42, for cutting the bubbles generated in the water flow.

[0075] The device incorporates a Venturi structure, which generates pressure changes within the jet section 1, creating shear force that shears the incoming airflow. This initial shearing breaks the gas into bubbles, merging the water and air to produce bubble water. By housing the jet section 1, mixing chamber 2, and bubble-cutting section 3 within the same casing 4, the volume of the bubble water generator is reduced, improving space utilization. The bubble-cutting section 3, located between the jet section 1 and the mixing chamber 2, and between the mixing chamber 2 and the outlet 42, further cuts bubbles that were not sufficiently sheared or coalesced in the Venturi structure, enhancing the bubble shearing effect and resulting in finer, more uniform bubbles in the final bubble water, ultimately forming micro-nano bubbles.

[0076] In this embodiment, a third arrangement is adopted. Specifically, the bubble cutting part 3 includes a first bubble cutting element 31 and a second bubble cutting element 32, and the first bubble cutting element 31 is disposed between the jet part 1 and the mixing chamber 2; the second bubble cutting element 32 is disposed between the mixing chamber 2 and the water outlet 42.

[0077] Specifically, the first bubble cutter 31 includes a first filter screen 311 and a second filter screen 312. Along the water flow direction, the first filter screen 311 and the second filter screen 312 are spaced apart, and the mesh size of the first filter screen 311 is smaller than that of the second filter screen 312. This structure shears the bubble-water mixture after passing through the jet section 1, making the bubbles finer and improving their mixing with the water. Specifically, the first filter screen 311 cuts the bubbles; the spaced-apart second filter screen 312 buffers the relatively turbulent water-air mixture after passing through the jet and the first filter screen 311. The sheared bubbles are slightly mixed and then passed through the second filter screen 312 at a slower flow rate for further shearing, resulting in finer bubbles. The different mesh sizes of the first filter screen 311 and the second filter screen 312 result in a better and finer bubble cutting effect.

[0078] Specifically, in this embodiment, the diameter of the second filter 312 is larger than the diameter of the first filter 311, and the second filter 312 is directly mounted on the jet member 12, forming a gap between it and the first filter 311. In other possible embodiments, the installation method of the filters is not specifically limited, and the number of filters can be adjusted according to the actual needs for bubble size.

[0079] Specifically, the second bubble cutter 32 includes a third filter 322, a fourth filter 323, and a through hole 321. The mixing chamber 2 and the outlet 42 are connected through the through hole 321, and the inner diameter of the through hole 321 gradually decreases along the water flow direction. The third filter 322 and the fourth filter 323 are respectively disposed at both ends of the through hole 321. Using the above structure, the through hole 321 of the second bubble cutter 32 achieves intense water flow collision through changes in the flow cross-section, forming a vortex that cuts the bubbles. Simultaneously, the third filter 322 and the fourth filter 323 are respectively disposed at both ends of the through hole 321, further cutting the bubbles as they pass through, ultimately forming micro-nano bubbles. In other possible embodiments, other structures can also be used as the second bubble cutter 32, as long as they can further cut the bubbles until they reach the micro-nano bubble level.

[0080] Specifically, in this embodiment, the third filter 322 and the fourth filter 323 have the same mesh size. In other possible embodiments, the mesh size of the fourth filter 323 can be greater than that of the third filter 322 to further improve the bubble shearing effect. Of course, the mesh size of the third filter 322 and the fourth filter 323 can also be adjusted according to actual needs, and is not limited here.

[0081] In this embodiment, as Figure 2 As shown, the jet section 1 includes a flow restrictor 11, a jet component 12, and an air inlet channel. The flow restrictor 11 is connected to both the water inlet and the jet component 12, and the air inlet channel is connected to the end of the jet component 12 closest to the flow restrictor 11. The jet component 12 has a Venturi structure. The flow restrictor 11 controls the flow rate of water entering the jet component 12, ensuring a more uniform water flow and a stable ratio of water to airflow, preventing excessive fluctuations in the water-to-bubble ratio and reducing user experience. The air inlet channel, located between the flow restrictor 11 and the jet component 12, utilizes Bernoulli's principle to allow external gas to enter the jet section 1 through the air inlet channel and converge with the water flow into the jet component 12. This eliminates the need for a pressurizing device such as an air pump, simplifying the structure. The venturi structure of the jet component 12 allows the water and airflow to mix and blend, creating bubble water. In other possible embodiments, the components of the jet section 1 are not specifically limited and can be matched according to actual needs, as long as they can obtain airflow and mix water flow with airflow to form bubble water.

[0082] Specifically, in this embodiment, such as Figure 2As shown, a gap is formed between the flow restrictor 11 and the jetting element 12, which serves as an air intake channel, allowing external gas to be connected. Utilizing Bernoulli's principle, external gas is drawn in, eliminating the need for additional piping as an air intake channel and saving on the overall volume of the bubble generating device. In other possible embodiments, the structure of the air intake channel is not specifically limited, as long as it can deliver external gas into the jetting element 12.

[0083] Furthermore, at least part of the inner diameter of the flow restrictor 11 is smaller than that of the inlet. This arrangement reduces the flow rate after the water passes through the flow restrictor 11, improves the stability of the water flow entering the jet nozzle 12, and ensures that the water and air flow enter evenly, avoiding excessive changes in water flow that could lead to an uneven ratio of water and air flow. At the same time, it can also change the flow velocity of the water, allowing the water to enter the jet nozzle 12 more quickly, generating a larger pressure change, and causing the air flow to be drawn into the jet nozzle 12 through the air intake channel.

[0084] The flow restrictor 11 includes a first channel 111 and a second channel 112. The two ends of the first channel 111 are connected to the inlet and the second channel 112, respectively. The inner diameter of the first channel 111 gradually decreases along the water flow direction. The two ends of the second channel 112 are connected to the first channel 111 and the jetting element 12, respectively. The inner diameter of the second channel 112 is smaller than the inner diameter of the first channel 111. At least a portion of the inner diameter of the first channel 111 is smaller than the inner diameter of the inlet. The gradually decreasing diameter of the first channel 111 causes a gradual decrease in water flow rate. The diameter of the second channel 112 is smaller than that of the first channel 111 and remains constant, thus gradually stabilizing the water flow and controlling its velocity. This ensures that both the flow rate and velocity are relatively stable when the water flows out of the flow restrictor 11.

[0085] Specifically, in this embodiment, the first channel 111 has a conical structure, with the diameter of the end connected to the inlet being larger than the diameter of the inlet, ensuring that the water flow is not obstructed when entering the inlet. The diameter of the first channel 111 gradually decreases, while the diameter of the end connected to the second channel 112 is larger than the diameter of the second channel 112, while the diameter of the second channel 112 remains unchanged, thus gradually stabilizing the water flow. In other possible embodiments, the specific structure of the flow restrictor 11 is not limited; it only needs to limit the flow rate and velocity of the water.

[0086] In this embodiment, the inner diameter of the jet component 12 gradually increases along the water flow direction; a plurality of protrusions 121 are provided on the inner wall surface of the jet component 12.

[0087] The multiple protruding structures 121 are arranged in three ways: First, the protruding structures 121 are spaced apart along the axial direction of the jet member 12; second, the multiple protruding structures 121 are spaced apart circumferentially along the inner wall surface; third, the protruding structures 121 are spaced apart along the axial direction of the jet member 12, and at the same time, the multiple protruding structures 121 are spaced apart circumferentially along the inner wall surface.

[0088] In this embodiment, a third arrangement is adopted. The Venturi structure generates negative pressure by changing the pipe diameter to draw in air. When the water-air mixture enters the interior through the inlet of the jet component 12, it generates high-frequency pressure fluctuations and high-speed, strong shearing forces, cutting the drawn-in gas into small bubbles. A protruding structure 121 is set as a vortex point, causing the passing water-air mixture to collide violently with the protruding structure 121, forming a vortex that further cuts the bubbles.

[0089] Furthermore, along the water flow direction, the distance between two adjacent protrusions 121 gradually increases; along the water flow direction, the radial dimension of the protrusion 121 gradually increases. This arrangement creates a gradient change, better disrupting the fluid flow and causing the bubble-water mixture to generate more eddies and velocity changes, thereby increasing the turbulence of the fluid. The enhanced turbulence makes the relative motion between the gas and liquid phases more intense, and the bubbles experience greater shear force in the turbulence, making them easier to break into smaller bubbles for more thorough cutting and effectively improving the cutting effect. In other possible embodiments, the number and size of the protrusions 121 can be set according to actual usage requirements, as long as it does not affect the thorough mixing of the airflow and water flow.

[0090] In this embodiment, a baffle 5 is provided inside the housing 4, and the periphery of the baffle 5 is connected to the inner wall of the housing 4 to separate the jet section 1 and the mixing chamber 2; the mixing chamber 2 and the jet component 12 are connected only through a connecting channel 6, on which a pump body is provided, wherein, Figure 2-3 The pump body is not shown, but those skilled in the art should understand that the pump body is installed on the connecting channel 6, which is common prior art and will not be described in detail in this embodiment. The pump body separates the jet section 1 and the mixing chamber 2 via a baffle 5, allowing both sections to be housed inside the casing 4 without interfering with each other. The jet section 1 and the mixing chamber 2 are connected only through the connecting channel 6, saving space in the bubble generating device. The pump body increases the water flow velocity, allowing the water to quickly enter the mixing chamber 2, achieving a violent collision effect.

[0091] In this embodiment, a water purifier is provided, including a bubble water generating device as described above.

[0092] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
