Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a water-using device and its control method. Background Technology

[0002] Microbubbles are tiny bubbles with a diameter of less than 50 μm. Under certain pressure, they are formed by thoroughly mixing gas (such as air) with water to create a gas-water solution. The solution then expands and releases the pressure, causing the dissolved gas to suddenly coalesce into tiny microbubbles, resulting in a milky white color. The resulting microbubble water has strong cleaning power; the pressure and heat generated when the microbubbles burst instantly remove dirt, achieving a deep cleaning effect.

[0003] Existing water-using appliances such as water heaters, water dispensers, and humidifiers generally lack the function of generating microbubbles, or only offer the concept without a concrete structure. Therefore, how to design a water-using appliance that can incorporate microbubble water generation is a problem that needs to be solved. Summary of the Invention

[0004] The purpose of this invention is to provide a water-using device and its control method, which can produce microbubble water for users and can adjust the flow rate of the output microbubble water as needed, thereby improving the user experience.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A water-using device includes a housing, a microbubble water generator disposed within the housing, and an outlet pipe connected to the microbubble water generator. The microbubble water generator includes a throat, a gas cutter, a bypass pipe, and a distribution valve. The gas cutter is disposed at the throat of the throat, allowing outside air to enter the throat through a micro-gap in the gas cutter and mix with water to form microbubble water. The bypass pipe connects both sides of the throat of the throat, and the diameter of the bypass pipe is larger than the maximum diameter of the throat. The distribution valve is configured to adjust the ratio of water flowing into the throat inlet and the bypass pipe to regulate the total flow rate of water output by the microbubble water generator.

[0007] Preferably, the distribution valve includes a knob, which, when turned, can adjust the ratio of water flowing into the throat inlet and the bypass pipe.

[0008] Preferably, the distribution valve includes an electric actuator configured to adjust the ratio of water flowing into the throat inlet and the bypass pipe.

[0009] Preferably, the gas cutting element is a gasket, which is stacked along the axial direction of the throat tube at the throat of the throat tube, and the micro-gap is formed between the gaskets.

[0010] Preferably, the sidewalls of the gaskets have a surface roughness, and the microgap is formed between the sidewalls of adjacent gaskets.

[0011] Preferably, the gasket has several shearing grooves on both sides of its axial direction.

[0012] Preferably, the microbubble water generator further includes an air inlet pipe, and the gas cutting element is a plate disposed in the air inlet pipe, the plate having a plurality of the micro gaps.

[0013] Preferably, the gas cutting element is a sintered filter element disposed at the throat, and the peripheral wall of the sintered filter element has a plurality of micro-gaps formed thereon.

[0014] Preferably, the microbubble water generator includes a bypass pipe that connects to both sides of the throat of the throat tube.

[0015] The present invention also provides a control method for the above-mentioned water-using equipment, comprising:

[0016] Receives the preset water flow rate set by the user;

[0017] Obtain the first flow rate of water entering the throat and the second flow rate of water entering the bypass pipe;

[0018] Calculate the total flow rate of water output by the microbubble water generator based on the first flow rate and the second flow rate;

[0019] When the total flow rate is not equal to the preset outflow rate, the proportion of water flowing into the throat inlet and the bypass pipe is controlled by the distribution valve until the recalculated total flow rate equals the preset outflow rate.

[0020] The beneficial effects of this invention are as follows: By incorporating a microbubble water generator with a gas cutting element, air can enter the throat through the micro-gap of the gas cutting element and mix with water to form microbubble water for user use. Furthermore, by setting up a bypass pipe and a distribution valve, the ratio of water flowing into the throat inlet and the bypass pipe can be adjusted, allowing for regulation of the output microbubble water flow rate as needed, thereby meeting the cleaning and sterilization requirements of different users and providing a better user experience. Moreover, since the output microbubble water flow rate can be adjusted solely through the microbubble water generator, the flow regulation components of existing water-using equipment can be omitted, further reducing manufacturing costs.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0040] This invention provides a water-using device capable of outputting microbubble water with adjustable flow rate, effectively meeting the cleaning and sterilization requirements of different users. Furthermore, the microbubble water also possesses sterilization and cleaning functions, resulting in a better user experience. Figure 1 and Figure 2 As shown, the aforementioned water-using equipment includes a housing 2 and a microbubble water generator 1 disposed within the housing 2. Water enters through the inlet of the microbubble water generator 1 and forms microbubble water, which then flows out through the outlet of the microbubble water generator 1 for user use. The aforementioned water-using equipment includes, but is not limited to, water heaters, water dispensers, humidifiers, etc. Any equipment that requires water output and has a demand for microbubble water falls within the scope of the water-using equipment covered by this invention.

[0041] In this embodiment, the microbubble water generator 1 includes a throat, a gas cutter 11, a bypass pipe 17, and a distribution valve 18. The gas cutter 11 is located at the throat of the throat, and outside air can enter the throat through the micro-gap of the gas cutter 11 and mix with water to form microbubble water.

[0042] The bypass pipe 17 is connected to both sides of the throat of the throat pipe. The distribution valve 18 is configured to adjust the ratio of water flowing into the throat pipe inlet and the bypass pipe 17, thereby adjusting the flow rate of water flowing out of the microbubble water generator 1. In this embodiment, when the distribution valve 18 controls the bypass pipe 17 to be in the open state (which can be partially open or fully open), the water output by the microbubble water generator 1 is specifically a mixture of microbubble water flowing out of the throat pipe and water flowing out of the bypass pipe 17, and it still has the function of microbubble water.

[0043] In one embodiment, exemplarily, such as Figure 2 and Figure 3 As shown, in this embodiment of the microbubble water generator 1, the gas cutting element 11 consists of multiple gaskets, which are stacked along the axial direction of the throat tube at the throat. By placing gaskets at the throat, air enters the throat tube through the micro-gap between the gaskets and mixes with water. Due to the small size of the micro-gap between the gaskets, the air can be sheared, thereby turning the air into finer air with higher pressure. Simultaneously, in conjunction with the throat tube structure, the water flow rate increases and the pressure decreases. This, combined with the higher-pressure finer air, allows more air to easily integrate into the water, resulting in microbubble water containing 10 bubbles per milliliter.6 The microbubble water generator 1 of this invention produces better microbubble water and can continuously generate microbubble water. Moreover, the microbubble water generator 1 of this invention can produce microbubble water with a bubble diameter of 47 micrometers at 0.3 MPa, which is smaller than the bubble particle size produced by bubble generators in the prior art, and achieves better cleaning effect.

[0044] like Figure 3 As shown, the microbubble water generator 1 includes a gasket, an air inlet pipe 12, a first pipe 13, and a second pipe 14, wherein:

[0045] One end of the second pipe 14 is sealed inside the first pipe 13, forming the aforementioned throat between them. A gasket is disposed at the throat of the throat. Exemplarily, a first liquid channel 131 can be formed inside the first pipe 13, with one end for water inlet. A second liquid channel 141 is formed inside the second pipe 14, with one end connected to the first liquid channel 131 and the other end capable of outputting microbubble water to mix with the water output from the bypass pipe 17. Along the direction pointing towards the gasket, the diameters of both the first liquid channel 131 and the second liquid channel 141 near the gasket gradually decrease to form a throat. When water flows into the throat, the throat generates an adsorption force that draws air into the micro-gap between the gaskets, where it is sheared into finer, higher-pressure air, which then mixes with the water to form microbubble water. In this embodiment, at least two gaskets are provided between the first liquid channel 131 and the second liquid channel 141, and the first liquid channel 131, the at least two gaskets, and the second liquid channel 141 are sequentially connected. Water can flow through the first liquid channel 131, through the gaskets, and finally out through the second liquid channel 141. Air can enter the throat through the micro-gap between the two gaskets and mix with water to form microbubble water.

[0046] Preferably, one end of the second pipe 14 is threaded to the first pipe 13, and a gasket is sandwiched between the first pipe 13 and the second pipe 14. The threaded connection between the second pipe 14 and the first pipe 13 achieves a fixed connection between them. More importantly, by screwing on the second pipe 14, the clamping force applied to the gasket by the second pipe 14 and the first pipe 13 can be adjusted, thereby adjusting the size of the micro-gap between the gaskets to meet the requirements for generating different microbubble water.

[0047] In this embodiment, the first pipe 13 is provided with an air inlet and an annular chamber 132 connected to the air inlet. An air intake channel 121 is opened in the air intake pipe 12, and the air intake pipe 12 is sealed to the air inlet so that the air intake channel 121 connects to the annular chamber 132. After the outside air flows into the annular chamber 132 through the air intake channel 121, it is distributed in an annular shape in the annular chamber 132, and then enters the micro gaps between the gaskets evenly along the circumference of the gaskets, so that the microbubble water generation is more uniform and the effect is better. In this embodiment, an air pump 10 can also be connected to one end of the air intake pipe 12. The air pump 10 pumps air into the air intake pipe 12. With the automatic adsorption of the throat, the air can be more easily dissolved in water, thereby making the formed microbubble water effect better. In addition, when the water pressure is too high, the air pump 10 can be used to boost the air to the throat, so that the air can be more easily dissolved in water.

[0048] In this embodiment, the connection between the intake pipe 12 and the first pipe 13 can also be achieved by threaded connection and sealed with a sealing ring.

[0049] In this embodiment, the aforementioned gasket can be set to two or more as needed, thereby creating multiple micro-gaps and making the microbubble water generation faster.

[0050] It is understandable that micro-gap is also formed between the gasket and the first pipe 13 and between the gasket and the second pipe 14 in this embodiment. This micro-gap can also be used to shear air to form tiny gas, which enters the liquid channel at a higher flow rate and mixes with the water in the liquid channel to form microbubble water.

[0051] In this embodiment, it can be referred to Figure 4 The aforementioned gaskets have a rough surface, which creates minute unevenness, resulting in micro-gaps between the two gaskets. Air passing through these micro-gaps is sheared and eventually mixes with water. The micro-gaps are formed solely by the inherent properties of the gasket material, eliminating the need for additional structures to aid in the generation of microbubbles. The structure is simple and easy to assemble.

[0052] As another preferred embodiment, a plurality of shear grooves 111 can be formed on the surfaces of the gaskets on both sides along the axial direction, and a micro gap is formed between the shear grooves 111 of two adjacent gaskets.

[0053] Optionally, the gasket can be made of a foam-like metal, in which case the shear groove 111 is a cavity in the foam-like metal. Alternatively, the gasket can be made of an alloy material, in which case the shear groove 111 can be created by directional etching. The gasket can also be cast from a porous plate, in which case the shear groove 111 is a cavity in the porous plate. Furthermore, the gasket can be formed by stacking layers of porous graphite, in which case the shear groove 111 is a cavity on the porous graphite.

[0054] In this embodiment, the plurality of shear grooves 111 can be arranged in parallel or crosswise. Figure 4 (as shown), to achieve shearing of the air inside the annular chamber 132.

[0055] For reference Figure 4 The aforementioned gasket includes a first sheet 112 and a second sheet 113 arranged in a stepped pattern, which are integrally formed. The diameter of the first sheet 112 is smaller than the diameter of the second sheet 113, and both the first sheet 112 and the second sheet 113 have shear grooves 111 on their surfaces. This gasket structure allows an annular space to be formed between its end face with the adjacent first pipe 13, the end face with the second pipe 14, and between two adjacent gaskets. When air flows into the annular chamber 132, the air is evenly distributed within the annular space, and then flows evenly into the micro-gap between the gasket and the first liquid channel 131, the micro-gap between the gaskets, and the micro-gap between the gasket and the second liquid channel 141, where it is sheared. This shearing process causes the fine air particles formed to be evenly mixed into the water, resulting in more uniform and comprehensive distribution of microbubble water.

[0056] In this embodiment, the gasket has a groove 114 on the side near the first liquid channel 131 and the second liquid channel 141, and a protrusion is provided at the end face of the first pipe 13 and the second pipe 14, which abuts against the groove 114. That is, the groove 114 and the protrusion allow the first pipe 13 and the second pipe 14 to clamp the gasket, thus fixing the gasket. More importantly, it makes the micro-gap formed by the shear groove 111 narrower, resulting in finer air shearing and a better microbubble water effect. It should be noted that the sidewall of the groove 114 in this embodiment can also have a shear groove 111.

[0057] For reference Figure 3 The microbubble water generator 1 in this embodiment also includes a third pipe 15, which is sealed to the end of the first pipe 13 away from the gasket, and the third pipe 15 has a third liquid channel 151 communicating with the first liquid channel 131. An inlet is provided on the third pipe 15 communicating with the third liquid channel 151, allowing water to enter the third liquid channel 151 through the inlet and then enter the first liquid channel 131. In this embodiment, one end of the third pipe 15 is placed inside the first pipe 13, and the two are sealed together by a sealing ring. It should be noted that the distribution valve 18 can divert the water in the inlet to control the water flow into one or both of the third liquid channel 151 and the bypass pipe 17 as needed.

[0058] Preferably, a detection device 16 is provided at one end of the third pipe 15. This detection device 16 is used to detect flow rate, pressure, and / or temperature. For example, the detection device 16 can be a temperature sensor to detect the temperature of the water flowing into the third liquid channel 151, a pressure sensor to detect the pressure of the water flowing into the third liquid channel 151, or a flow sensor to detect the flow rate of the water flowing into the third liquid channel 151. Devices that simultaneously detect two or more of temperature, pressure, and flow rate can also be used. By detecting flow rate, pressure, and / or temperature, a controller can be used to control the water flow rate, pressure, and temperature to meet different needs.

[0059] Preferably, in this embodiment, the bypass pipe 17 connects to both sides of the throat of the throat pipe. By providing the bypass pipe 17, water can flow through the throat of the throat pipe and mix with fine air to form microbubble water, while another part mixes with the formed microbubble water, thereby changing the bubble content in the microbubble water flowing out of the outlet. In this embodiment, one end of the bypass pipe 17 is connected to the inlet of the third pipe 15, and the other end is connected to the second pipe 14 (… Figure 5 As shown, the second pipe 14 has a connecting hole 142 that connects to the second liquid channel 141, and the bypass pipe 17 is sealed and connected to the connecting hole 142. In this embodiment, the diameter of the bypass pipe 17 is larger than the maximum diameter of the throat pipe.

[0060] In this embodiment, the distribution valve 18 has its inlet connected to the liquid inlet of the third pipe 15, and two outlets connected to the bypass pipe 17 and the third liquid channel 151, respectively. The distribution valve 18 allows adjustment of the ratio of water entering the bypass pipe 17 and the third liquid channel 151, thereby adjusting the total flow rate of water exiting the microbubble water generator 1. Furthermore, by adjusting the ratio of water entering the bypass pipe 17 and the third liquid channel 151, the bubble content of the microbubble water formed in the throat of the throat tube can also be adjusted. Moreover, by mixing the water in the bypass pipe 17 with the microbubble water formed in the second liquid channel 141, the bubble content of the final microbubble water can be adjusted to meet the requirements of different users. In addition, by setting the distribution valve 18, this embodiment can adjust the pressure of the water entering the throat tube, thereby preventing excessive water pressure from preventing air from effectively dissolving, thus further increasing the probability of microbubble water generation. The above-mentioned distribution valve 18 is a common structure in the prior art, and its structure and principle will not be discussed here.

[0061] In this embodiment, the proportion of water entering the bypass pipe 17 and the third liquid channel 151 is adjusted by the distribution valve 18. Specifically, when the flow rate of water entering the bypass pipe 17 is increased, the flow rate entering the third liquid channel 151 will decrease. Since the diameter of the bypass pipe 17 is larger than the maximum diameter of the throat, the flow rate of water entering the bypass pipe 17 is adjusted. Although the flow rate of water in the throat will also change, the total output flow rate of the entire microbubble water generator 1 is adjusted by adjusting the flow rate of water in the bypass pipe 17, thus achieving the flow rate regulation of the entire water-using equipment.

[0062] Furthermore, the aforementioned distribution valve 18 may include a knob, which allows the user to adjust the ratio of water flowing into the throat inlet and the bypass pipe 17 by turning the knob. Optionally, the aforementioned distribution valve 18 may also include an electric actuator, which allows for adjustment of the ratio of water flowing into the throat inlet and the bypass pipe 17.

[0063] In another preferred embodiment, the microbubble water generator 1 described above can also be as follows: Figure 6 The structure shown illustrates that the microbubble water generator 1 includes a throat and an air inlet pipe 12 connected to the throat of the throat. A plate (which is the gas cutter 11 in this embodiment) is installed inside the air inlet pipe 12. The plate has multiple micro-gap structures, allowing air to enter the throat and mix with water to form microbubble water. By placing a plate inside the air inlet pipe 12 with multiple micro-gap structures, air can be sheared into multiple streams of higher-pressure fine air through these gaps. Simultaneously, the water flow rate within the throat is increased while the pressure decreases. This, combined with the higher-pressure fine air, allows for greater and easier integration of air into the water, resulting in microbubble water containing up to 10 bubbles per milliliter. 6 The microbubble water generator 1 of this invention produces better microbubble water and can continuously generate microbubble water. Moreover, the microbubble water generator 1 of this invention can produce microbubble water with a bubble diameter of 47 micrometers at 0.3 MPa, which is smaller than the bubble particle size produced by bubble generators in the prior art, and achieves better cleaning effect.

[0064] Specifically, such as Figure 6 and Figure 7 As shown, the microbubble water generator 1 includes a plate, an air inlet pipe 12, a first pipe 13, and a second pipe 14, wherein:

[0065] One end of the second pipe 14 is sealed inside the first pipe 13, forming the aforementioned throat between them. An air intake passage 121 is provided inside the air intake pipe 12, which connects to the throat of the throat. Exemplarily, a first liquid passage 131 can be provided inside the first pipe 13, allowing water to flow into it. The end of the first liquid passage 131 near the second pipe 14 includes a first diameter-reducing section 1311, whose diameter gradually decreases along the direction pointing towards the second pipe 14. A second liquid passage 141 is provided in the second pipe 14, with one end connected to the first liquid passage 131. The second liquid channel 141, near the end of the first liquid channel 131, includes a second variable-diameter section 1411 and a constant-diameter section 1412. The constant-diameter section 1412 connects the second variable-diameter section 1411 and the first variable-diameter section 1311 (i.e., the constant-diameter section 1412 is the throat of the throat tube). Along the direction pointing towards the first pipe 13, the diameter of the second variable-diameter section 141 gradually decreases. With this structure, the first liquid channel 131 and the second liquid channel 141 together form the aforementioned throat tube structure. When water flows into the throat tube, the throat tube generates an adsorption force that draws air into the micro-gap of the plate, where it is sheared into finer, higher-pressure air. This fine air is then drawn to the throat and mixes with water to form microbubble water.

[0066] In this embodiment, a threaded connection hole 133 is provided in the middle of the first pipe 13. Figure 8 and Figure 9 As shown), a connection hole 144 is provided on the second pipe 14. Figure 7 and Figure 10 As shown), the connecting hole 144 connects the equal diameter section 1412 and the threaded connecting hole 133. One end of the air intake pipe 12 is threaded to the threaded connecting hole 133 so that the air intake channel 121 is connected to the connecting hole 144 to form the aforementioned air intake channel 121, thereby allowing air to enter the throat of the throat pipe through the air intake channel 121 and mix with water.

[0067] Preferably, refer to Figures 7-10The first liquid channel 131 within the first pipe 13, without the first diameter reducing section 1311, has a stepped structure at one end. Correspondingly, the second pipe 14, near the first pipe 13, also has a stepped structure at one end. This facilitates the positioning of the portion of the second pipe 14 within the first pipe 13, ensuring that the connecting hole 144 on the second pipe 14 aligns with the threaded connecting hole 133 on the first pipe 13, allowing air to smoothly enter the throat of the throat. Furthermore, it improves the sealing performance of the connection between the first pipe 13 and the second pipe 14, preventing gas leakage at the connection point. More preferably, the outer wall of the portion of the second pipe 14 within the first pipe 13 has several sealing grooves 143, within which sealing rings can be placed to further enhance the sealing performance between the first pipe 13 and the second pipe 14.

[0068] In this embodiment, one end of the second pipe 14 is fixedly connected to the first pipe 13 by bolts. Specifically, flange structures can be provided on the first pipe 13 and the second pipe 14, and then the first pipe 13 and the second pipe 14 are fixed by bolts and flange structures. The first pipe 13 and the second pipe 14 can also be fixed by other methods such as threaded connection, as long as the connecting hole 144 can be aligned with the threaded connecting hole 133.

[0069] The aforementioned plate is disposed within the threaded connection hole 133 and can be fixed by abutting one end of the air intake pipe 12. The plate has multiple micro-gap sections. Air enters through the air intake channel 121 of the air intake pipe 12, passes through the plate, flows into the threaded connection hole 133 via the micro-gap sections, and finally flows into the throat of the throat pipe through the connection hole 144. Because there are multiple micro-gap sections, the air can be sheared and divided into multiple streams of higher-pressure fine air. These fine air streams mix with water to form microbubble water.

[0070] In this embodiment, multiple plates can be configured, spaced apart. These multiple plates allow for repeated shearing and segmentation of the air, resulting in finer air entering the threaded connection hole 133 and thus enhancing the microbubble water effect. Preferably, the micro-gap of the multiple plates is staggered to improve the shearing effect on the air, causing it to be sheared into more strands, thereby increasing the number of bubbles in the microbubble water.

[0071] For example, the aforementioned plate can be made of foam-like metal, in which case the micro-gaps are formed by the pores of the foam-like metal. The aforementioned plate can also be made of porous plate or porous graphite, in which case the micro-gaps are formed by the pores on it.

[0072] In this embodiment, a one-way valve (not shown in the figure) is provided in the air intake channel 121. It is preferably provided in the air intake channel 121 of the air intake pipe 12, and the one-way valve is provided upstream of the plate to prevent water from flowing into the air intake channel 121 through the threaded connection hole 133.

[0073] For reference Figure 7 The microbubble water generator 1 in this embodiment further includes a third pipe 15, which is sealed to one end of the second pipe 14, and the third pipe 15 has a fourth liquid channel 152 communicating with the second liquid channel 141. An outlet communicating with the fourth liquid channel 152 is provided on the third pipe 15, which is used to output the final microbubble water for user use. In this embodiment, the third pipe 15 and the second pipe 14 are sealed together by a threaded connection and a sealing ring.

[0074] In this embodiment, an air pump 10 can also be connected to one end of the air intake pipe 12. The air pump 10 pumps air into the air intake pipe 12, and with the automatic adsorption of the throat, the air can be more easily dissolved in the water, thus making the formed microbubble water effect better. In addition, when the water pressure is too high, the air pump 10 can be used to boost the air to the throat, making the air more easily dissolved in the water.

[0075] Preferably, in this embodiment, the bypass pipe 17 is connected to both sides of the throat of the throat tube. By providing the bypass pipe 17, water can partially flow through the throat of the throat tube and mix with fine air to form microbubble water, while the other part mixes with the formed microbubble water, thereby changing the bubble content in the microbubble water flowing out of the outlet. In this embodiment, one end of the bypass pipe 17 is connected to the inlet of the first pipe 13, and the other end is connected to the second pipe 14 (… Figure 10 As shown, the second pipe 14 has a connecting hole 142 that connects to the second liquid channel 141, and the bypass pipe 17 is sealed and connected to the connecting hole 142. In this embodiment, the diameter of the bypass pipe 17 is larger than the maximum diameter of the throat pipe.

[0076] In this embodiment, the distribution valve 18 has its inlet connected to the liquid inlet of the first pipe 13, and two outlets connected to the bypass pipe 17 and the first liquid channel 131, respectively. The distribution valve 18 allows adjustment of the ratio of water entering the bypass pipe 17 and the first liquid channel 131, thereby adjusting the total flow rate of microbubble water exiting the microbubble water generator 1. Furthermore, by adjusting the ratio of water entering the bypass pipe 17 and the third liquid channel 151, the distribution valve 18 alters the bubble content of the microbubble water formed in the throat. Moreover, the mixing of water in the bypass pipe 17 with the microbubble water formed in the second liquid channel 141 further adjusts the bubble content of the final microbubble water, meeting the requirements of different users. Additionally, by setting the distribution valve 18, this embodiment can adjust the pressure of the water entering the throat, preventing excessive water pressure from hindering air dissolution and thus further increasing the probability of microbubble water generation. The distribution valve 18 described above is a common structure in the prior art, and its structure and principle will not be discussed here.

[0077] The proportion of water entering the bypass pipe 17 and the third liquid channel 151 is adjusted by the distribution valve 18. Specifically, when the flow rate of water entering the bypass pipe 17 is increased, the flow rate entering the third liquid channel 151 decreases. Since the diameter of the bypass pipe 17 is larger than the maximum diameter of the throat pipe, adjusting the flow rate of water entering the bypass pipe 17, although changing the flow rate in the throat pipe, results in the overall output flow rate of the microbubble water generator 1 being adjusted based on the flow rate of water entering the bypass pipe 17. This achieves flow rate regulation for the entire water-using equipment.

[0078] Furthermore, the aforementioned distribution valve 18 may include a knob, which allows the user to adjust the ratio of water flowing into the throat inlet and the bypass pipe 17 by turning the knob. Optionally, the aforementioned distribution valve 18 may also include an electric actuator, which allows for adjustment of the ratio of water flowing into the throat inlet and the bypass pipe 17.

[0079] In another preferred embodiment, the microbubble water generator 1 described above can also be as follows: Figure 11 and Figure 12 The structure shown, specifically, is as follows: Figure 11 and Figure 12As shown, the microbubble water generator 1 includes a throat tube, and sintered filter elements (which are the gas cutting element 11 of this invention) are stacked along the axial direction of the throat tube. Air can enter the throat tube through the micropores of the sintered filter element and mix with water to form microbubble water. This invention, by setting a sintered filter element at the throat tube, allows air to enter the throat tube and mix with water due to the micropore structure of the sintered filter element itself. Because the micropores of the sintered filter element are small, they can shear the air, thus turning it into finer air with higher pressure. Simultaneously, the throat tube structure increases the water flow rate and lowers the pressure. Combined with the higher-pressure finer air, this allows more air to easily and readily integrate into the water, resulting in microbubble water containing up to 10 bubbles per milliliter. 6 The microbubble water generator 1 of this invention produces better microbubble water and can continuously generate microbubble water. Moreover, the microbubble water generator 1 of this invention can produce microbubble water with a bubble diameter of 47 micrometers at 0.3 MPa, which is smaller than the bubble particle size produced by bubble generators in the prior art, and achieves better cleaning effect.

[0080] like Figure 11 and Figure 12 As shown, the microbubble water generator 1 includes a sintered filter element, an air inlet pipe 12, a first pipe 13, and a second pipe 14, wherein:

[0081] One end of the second pipe 14 is sealed inside the first pipe 13, and the two together form a throat with the sintered filter element, which is disposed at the throat of the throat. Exemplarily, a first liquid channel 131 is provided inside the first pipe 13, one end of which is used for water entry. The end of the first liquid channel 131 near the second pipe 14 includes a first diameter-reducing section 1311, and the diameter of the first diameter-reducing section 1311 gradually decreases along the direction pointing towards the second pipe 14. A second liquid channel 141 is provided in the second pipe 14, one end of which is connected to the first liquid channel 131, and the other end... The second liquid channel 141 includes a second variable diameter section 1411 at its end near the first liquid channel 131. Along the direction pointing towards the first pipe 13, the diameter of the second variable diameter section 1411 gradually decreases. A sintered filter element is disposed between the first variable diameter section 1311 and the second variable diameter section 1411. This structure allows the first liquid channel 131, the sintered filter element, and the second liquid channel 141 to collectively form the aforementioned throat structure. When water flows into the throat, the throat generates an adsorption force that draws air into the micro-gap between the sintered filter elements, where it is sheared into finer, higher-pressure air, which then mixes with the water to form microbubble water.

[0082] A threaded connection hole 133 is provided on the first pipe 13, which is positioned directly opposite the sintered filter element. Through this threaded connection hole 133, outside air can flow to the sintered filter element and then enter the throat through the micro-gap of the sintered filter element. In addition, the air intake pipe 12 of this embodiment can be threaded to the threaded connection hole 133. An air intake channel 121 is provided in the air intake pipe 12, which is connected to the threaded connection hole 133. Outside air can enter the air intake channel 121 and the threaded connection hole 133, and finally enter the micro-gap of the sintered filter element.

[0083] Preferably, one end of the second pipe 14 is fixedly connected to the first pipe 13 by bolts. Specifically, flange structures can be provided on the first pipe 13 and the second pipe 14, and then the first pipe 13 and the second pipe 14 are fixed by bolts and flange structures. The first pipe 13 and the second pipe 14 can also be fixed by other methods such as threaded connection.

[0084] In this embodiment, a rubber gasket 19 is provided between the sintered filter element and the first pipe 13. This rubber gasket 19 prevents water flow from impacting the sintered filter element and causing damage. The water pressure is buffered by the rubber gasket 19 and does not directly act on the end face of the sintered filter element, thus effectively protecting it. Furthermore, the rubber gasket 19 also prevents the sintered filter element from being damaged by impact or pressure during the assembly of the microbubble water generator 1 in this embodiment.

[0085] For reference Figure 12 The microbubble water generator 1 in this embodiment also includes a third pipe 15, which is sealed to the end of the first pipe 13 away from the sintered filter element, and the third pipe 15 has a third liquid channel 151 that communicates with the first liquid channel 131. An inlet is provided on the third pipe 15 that communicates with the third liquid channel 151, allowing water to enter the third liquid channel 151 through the inlet and then enter the first liquid channel 131. In this embodiment, one end of the third pipe 15 is placed inside the first pipe 13, and the two are fixedly connected by a flange and bolts, with a sealing ring between them for sealing. It should be noted that the distribution valve 18 can divert the water in the inlet to control the water flow into one or both of the third liquid channel 151 and the bypass pipe 17 as needed.

[0086] Preferably, a detection device 16 is provided at one end of the third pipe 15. This detection device 16 is used to detect flow rate, pressure, and / or temperature. For example, the detection device 16 can be a temperature sensor to detect the temperature of the water flowing into the third liquid channel 151, a pressure sensor to detect the pressure of the water flowing into the third liquid channel 151, or a flow sensor to detect the flow rate of the water flowing into the third liquid channel 151. Devices that simultaneously detect two or more of temperature, pressure, and flow rate can also be used. By detecting flow rate, pressure, and / or temperature, a controller can be used to control the water flow rate, pressure, and temperature to meet different needs.

[0087] In this embodiment, an air pump 10 can also be connected to one end of the air intake pipe 12. The air pump 10 pumps air into the air intake pipe 12, and with the automatic adsorption of the throat, the air can be more easily dissolved in the water, thus making the formed microbubble water effect better. In addition, when the water pressure is too high, the air pump 10 can be used to boost the air to the throat, making the air more easily dissolved in the water.

[0088] Preferably, in this embodiment, the bypass pipe 17 connects to both sides of the throat of the throat pipe. By providing the bypass pipe 17, water can flow through the throat of the throat pipe and mix with fine air to form microbubble water, while another part mixes with the formed microbubble water, thereby changing the bubble content in the microbubble water flowing out of the outlet. In this embodiment, one end of the bypass pipe 17 is connected to the inlet of the third pipe 15, and the other end is connected to the second pipe 14 (… Figure 12 As shown, the second pipe 14 has a connecting hole 142 that connects to the second liquid channel 141, and the bypass pipe 17 is sealed and connected to the connecting hole 142.

[0089] In this embodiment, the distribution valve 18 has its inlet connected to the liquid inlet of the third pipe 15, and two outlets connected to the bypass pipe 17 and the third liquid channel 151, respectively. The distribution valve 18 allows adjustment of the ratio of water entering the bypass pipe 17 and the third liquid channel 151, thereby adjusting the total flow rate of microbubble water exiting the microbubble water generator 1. Furthermore, by adjusting the ratio of water entering the bypass pipe 17 and the third liquid channel 151, the bubble content of the microbubble water formed in the throat of the throat tube can also be adjusted. Moreover, by mixing the water in the bypass pipe 17 with the microbubble water formed in the second liquid channel 141, the bubble content of the final microbubble water can be adjusted to meet the requirements of different users. In addition, by setting the distribution valve 18, this embodiment can adjust the pressure of the water entering the throat tube, thereby preventing excessive water pressure from preventing air from effectively dissolving, thus further increasing the probability of microbubble water generation. The distribution valve 18 described above is a common structure in the prior art, and its structure and principle will not be discussed here.

[0090] Furthermore, the aforementioned distribution valve 18 may include a knob, which allows the user to adjust the ratio of water flowing into the throat inlet and the bypass pipe 17 by turning the knob. Optionally, the aforementioned distribution valve 18 may also include an electric actuator, which allows for adjustment of the ratio of water flowing into the throat inlet and the bypass pipe 17.

[0091] The present invention also provides a control method for the above-mentioned water-using equipment, specifically, as follows: Figure 13 As shown, the control method includes the following steps:

[0092] S1: Receive the preset water flow rate set by the user.

[0093] When using water-using equipment, users can set different preset water flow rates according to their different water needs via remote control, APP, or the touch panel on the equipment. This preset water flow rate is the flow rate that brings the best water experience to the user, and its value varies from user to user.

[0094] S2. Obtain the first flow rate of water entering the throat and the second flow rate of water entering the bypass pipe.

[0095] After obtaining the preset water flow rate set by the user, the water-using equipment will detect the first flow rate of water entering the throat pipe and the second flow rate of water entering the bypass pipe 17.

[0096] S3. Calculate the total flow rate of water output by the microbubble water generator based on the first flow rate and the second flow rate.

[0097] After obtaining the first and second flow rates, the total flow rate of water output by microbubble water generator 1 is obtained by referring to a pre-stored table showing the correspondence between the first and second flow rates and the total flow rate of water output by the microbubble water generator. This correspondence table was obtained through multiple comparative tests before leaving the factory; the specific test methods will not be detailed here.

[0098] S4. When the total flow rate is not equal to the preset outflow rate, the proportion of water flowing into the throat inlet and the bypass pipe is controlled by the distribution valve until the recalculated total flow rate equals the preset outflow rate.

[0099] After obtaining the total flow rate of water output from the microbubble water generator 1, it is determined whether the total flow rate is the same as the preset outflow rate. If they are the same, there is no need to adjust the flow rate of water flowing into the throat pipe and bypass pipe 17. At this time, the distribution valve 18 does not operate.

[0100] When the total flow rate is not equal to the preset outlet flow rate, the proportion of water flowing into the inlet of the throat pipe and the bypass pipe 17 is controlled by the distribution valve 18 until the recalculated total flow rate equals the preset outlet flow rate. During this adjustment process, the water equipment can directly obtain the flow rate of water flowing into the throat pipe and bypass pipe 17 corresponding to the preset outlet flow rate (at this time, the preset outlet flow rate is the total flow rate) according to the above correspondence table. The distribution valve 18 distributes the water flowing into the throat pipe and bypass pipe 17 according to the obtained flow rate of water flowing into the throat pipe and bypass pipe 17 to achieve the final outlet flow rate requirement.

[0101] If the user-defined preset water flow rate is not stored in the above-mentioned correspondence table, the total flow rate with the smallest difference from the user-defined preset water flow rate in the correspondence table can be selected. Then, the distribution valve 18 adjusts the flow rate of the water entering the throat and bypass pipe 17 according to the total flow rate with the smallest difference. That is, although the user-defined preset water flow rate is not precisely reached, the total flow rate obtained after adjustment is not much different from the preset water flow rate, which can also meet the user's requirements.

[0102] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
