[0060] Example 1

[0061] This embodiment provides a micro bubble generator, such as Figures 1 to 4 As shown, in one embodiment, the microbubble generator 100 includes a main body 110, an input structure 120, an output structure 130 and a throttling structure 140. The main body 110 is provided with an inner cavity 111, and the inner cavity 111 can provide a closed, high-pressure gas dissolution space, which is conducive to improving the solubility of the gas in the liquid. The input structure 120 is connected to the main body 110, and the input structure 120 is provided with an input channel 122, and the input channel 122 is connected to the inner cavity 111, and the raw materials of microbubble water can be input into the inner cavity 111. The output structure 130 is connected to the main body 110, and the output structure 130 is provided with an output channel 132, and the output channel 132 is connected to the inner cavity 111, and the product, i.e., microbubble water, can be output. At least part of the throttling structure 140 is arranged in the output channel 132, and the throttling structure 140 is provided with at least one throttling channel 142, and each throttling channel 142 is connected to the output channel 132. Each throttling channel 142 includes a tapered section 144 , and the tapered section 144 is arranged to be tapered in the discharge direction of the liquid.

[0062] By setting a throttling structure 140 in the output channel 132, the throttling structure 140 has at least one throttling channel 142. When the liquid containing dissolved gas flows through the tapered section 144 of the throttling channel 142, since the tapered section 144 is tapered in the output direction of the liquid, its flow cross-sectional area is continuously reduced, the flow rate of the liquid is continuously increased, the pressure is gradually reduced, and the gas is continuously precipitated due to the reduction of solubility, generating a large number of microbubbles, forming microbubble water, and flowing out through the output channel 132 or directly flowing out from the output end of the throttling channel 142. Therefore, the microbubble generator 100 can prepare microbubble water while the liquid containing dissolved gas is output from the output channel 132 by integrating the throttling structure 140 in the output channel 132, without using multiple connected devices to prepare microbubble water in steps, thereby simplifying the preparation structure. Moreover, the microbubble generator 100 also increases the concentration of microbubbles in the microbubble water through the tapered section 144, thereby improving the working efficiency.

[0063] It should be noted that the liquid may be, but is not limited to, water or a water-gas mixture. Of course, other liquid media suitable for preparing microbubble water are also possible. The gas may be air, oxygen or other suitable gases. Among them, under different pressure conditions, the solubility of air and oxygen in water is different, and the higher the pressure, the greater the solubility. In this embodiment, water and air are used as examples for illustration, but are not limited to this exemplary description.

[0064] The main body 110 includes a first shell 112, a second shell 113 and a sealing ring 114. The first shell 112 and the second shell 113 are covered and arranged to form an inner cavity 111. The sealing ring 114 is arranged at the connection between the first shell 112 and the second shell 113, and seals the connection between the two to generate a high-pressure environment in the inner cavity 111. Among them, the input structure 120 is arranged in the first shell 112, and the output structure 130 is arranged in the second shell 113. In this embodiment, the first shell 112 and the second shell 113 are arranged up and down. Obviously, in other embodiments, the first shell 112 and the second shell 113 can be arranged left and right.

[0065] Specifically, a convex ring 115 is provided at the connection of the first shell 112, and an annular groove 116 is provided at the connection of the second shell 113. The sealing ring 114 is received in the annular groove 116, and the convex ring 115 squeezes the sealing ring 114. The convex ring 115 can increase its squeezing pressure on the sealing ring 114, thereby improving the sealing effect and providing a closed and high-pressure condition for the gas dissolution in the inner cavity 111. Moreover, the provision of the annular groove 116 facilitates the installation of the sealing ring 114 and can also play a role in positioning the sealing ring 114.

[0066] Further, the first shell 112 is provided with a plurality of first screw holes 117, and the second shell 113 is provided with a plurality of second screw holes 118, and the plurality of first screw holes 117 are arranged one by one with the plurality of second screw holes 118. The first screw holes 117 and the second screw holes 118 are locked and connected by screws (not shown) to fix the first shell 112 and the second shell 113, and to tighten the sealing ring 114 to ensure that the microbubble generator 100 does not leak under high pressure conditions. It is understandable that in other embodiments, the first shell 112 and the second shell 113 can be fixed by bonding or welding without opening screw holes.

[0067] In order to improve the structural strength of the first shell 112 and the second shell 113, the outer surfaces of the first shell 112 and the second shell 113 are provided with a plurality of reinforcing ribs 119, and all the reinforcing ribs 119 on the first shell 112 are arranged in a criss-cross manner as a whole, and all the reinforcing ribs 119 on the second shell 113 are also arranged in a criss-cross manner, and the longitudinally extending reinforcing ribs 119 on the first shell 112 are aligned with the longitudinally extending reinforcing ribs 119 on the second shell 113 to improve the structural strength of the main body 110 as a whole.

[0068] In this embodiment, the main body 110 is overall similar to an ellipsoid, but its shape is not limited thereto and can be set according to actual needs, such as a cylindrical, cubic, spherical or other shapes.

[0069] In this embodiment, two input structures 120 are provided on the first shell 112, wherein the input channel 122 of one input structure 120 is used to input water or a water-gas mixture, and the input channel 122 of the other input structure 120 is used to input air or oxygen. It should be noted that in other embodiments, only one input structure 120 may be provided on the first shell 112, and its input channel 122 is connected to the vortex pump, so that water and air can be input at the same time. Of course, more input structures 120 may be provided on the first shell 112 according to actual conditions, and are not limited to the above situation.

[0070] In this embodiment, the input structure 120 is integrally formed with the first shell 112, which further simplifies the structure of the microbubble generator 100 and facilitates processing and manufacturing. Among them, the input structure 120 is tubular, and its inner end does not extend into the inner cavity 111, and its outer end can be connected to an external device through a pipeline. Obviously, in other embodiments, the input structure 120 can also adopt other shapes, not limited to tubular, its inner end can extend into the inner cavity 111, and its input channel 122 can include more than two sections of connected channels.

[0071] In this embodiment, an output structure 130 is provided on the second shell 113, however, the number of output structures 130 is not limited to one. Moreover, the output structure 130 is integrally formed with the second shell 113, which is also conducive to simplifying the structure of the microbubble generator 100 and facilitating processing and manufacturing. Among them, the output structure 130 is also tubular, and its inner end does not extend into the inner cavity 111, and its outer end outputs microbubble water. Obviously, in other embodiments, the shape of the output structure 130 is not limited to tubular, and its inner end can extend into the inner cavity 111, so that both ends of the throttling channel 142 are connected to its output channel 132, and its output channel 132 can include more than two sections of connected channels.

[0072] See also Figure 5 , combined with Figure 4 , Figure 5 Shows Figure 4 A partial enlarged view of the A region of the micro-bubble generator, each throttling channel 142 also includes a transition section 146, which is connected to the output end of the tapered section 144, and the transition section 146 is arranged flush in the output direction of the liquid. When the liquid flows through the transition section 146, its flow cross-sectional area is always small, and the liquid maintains a large flow rate and a small pressure. In this process, more air is quickly precipitated from the water, generating more and smaller microbubbles, further increasing the concentration of microbubbles, and the working efficiency of the microbubble generator 100 is further improved.

[0073] Furthermore, each throttling channel 142 also includes a gradually expanding section 148, which is connected to the output end of the transition section 146. The gradually expanding section 148 is gradually expanded in the output direction of the liquid to reduce the flow rate of the microbubble water and prevent it from being ejected from the output end of the throttling channel 142.

[0074] In this embodiment, the throttling structure 140 is provided with a throttling channel 142, the input end of the throttling channel 142 is connected to the inner cavity 111, and the output end of the throttling channel 142 is connected to the output channel 132. Among them, the input end of the tapered section 144 is connected to the inner cavity 111, and the output end of the gradually expanding section 148 is connected to the output channel 132. The output channel 132 can further reduce the flow rate of the microbubble water, so that the microbubble water flows out relatively smoothly from the output end of the output channel 132. Among them, one end of the throttling structure 140 does not extend into the inner cavity 111, and the other end is located in the output channel 132, so that the entire throttling structure 140 is completely located in the output channel 132. It can be understood that, in other embodiments, one end of the throttling structure 140 can extend into the inner cavity 111, and partially be located outside the output channel 132, and the other end is located in the output channel 132; or, one end of the throttling structure 140 can be located in the output channel 132, and the other end extends out of the outer end of the output channel 132; or, both ends of the throttling structure 140 are located in the output channel 132, and one end thereof is connected to the inner cavity 111 through the output channel 132.

[0075] In order to increase the output of microbubble water to meet different application scenarios, in other embodiments, the throttling structure 140 may be provided with a plurality of throttling channels 142, the plurality of throttling channels 142 are arranged at intervals, the input ends of the plurality of throttling channels 142 are directly or indirectly connected to the inner cavity 111, and the output ends of the plurality of throttling channels 142 are connected to the output channel 132. The plurality of throttling channels 142 may be arranged side by side or in a circular manner, or may be arranged in a manner of multiple surrounding one or in other suitable manners.

[0076] In this embodiment, the throttling structure 140 is integrally formed with the output structure 130, and the throttling structure 140 does not need to be assembled in the output channel 132. The second housing 113, the output structure 130 and the throttling structure 140 are integrally prepared, so that the structure of the microbubble generator 100 is more streamlined. It should be noted that in other embodiments, the throttling structure 140 can be fixed in the output channel 132 by bonding, or fixed in the output channel 132 by clamping, or fixed in the output channel 132 by threading.

[0077] See also Figure 6 and Figure 7 , combined with Figure 4 , Figure 6 Shows Figure 4 A partial enlarged view of the B area of ​​the micro bubble generator. Figure 7The schematic diagram of the structure of the flow diversion structure of the microbubble generator in this embodiment is shown. The microbubble generator 100 also includes a flow diversion structure 150, which is arranged on the cavity wall of the inner cavity 111 and has a flow diversion portion 151. The flow diversion portion 151 is arranged corresponding to the inner end of the input channel 122 of an input structure 120, and has a first flow diversion surface 151a and a second flow diversion surface 151b intersecting at an acute angle. In other words, the flow diversion portion 151 is wedge-shaped, with its tip facing the inner end of the input channel 122, and divides the water flow, so that the water flow flows along the first flow diversion surface 151a and the second flow diversion surface 151b respectively, which increases the contact area between water and air, reduces the water flow speed, prolongs the contact time between water and air, and improves the efficiency of air dissolving in water.

[0078] The flow dividing structure 150 includes a first flow dividing sheet 152 and a second flow dividing sheet 153 which are arranged to intersect. The flow dividing portion 151 is formed at one end of the first flow dividing sheet 152, the first flow dividing surface 151a is a side surface of the first flow dividing sheet 152, and the second flow dividing surface 151b is an inclined surface arranged at one end of the first flow dividing sheet 152. The second flow dividing sheet 153 is provided with a notch 154 corresponding to the flow dividing portion 151, and the notch 154 has two notch side surfaces 155, and the two notch side surfaces 155 are arranged opposite to each other in the extension direction of the input channel 122, one of the notch side surfaces 155 intersects with the first flow dividing surface 151a, and the other notch side surface 155 is arranged at a distance from the second flow dividing surface 151b. The notch 154 can further divide the water flow passing through the first diverter surface 151a and the second diverter surface 151b, so that the water flow can flow along the two sides of the second diverter plate 153, further increasing the contact area between water and air, reducing the water flow speed, and lengthening the contact time between water and air, thereby increasing the efficiency of air dissolving in water.

[0079] The notch 154 also has a notch bottom surface 156, which is connected to a notch side surface 155. The second diverter surface 151b extends to the second diverter plate 153 and intersects with the notch bottom surface 156. Through the drainage of the second diverter surface 151b, part of the water flow will flow to the notch bottom surface 156, and then flow to the connected notch side surface 155, thereby forming turbulence, allowing water and air to contact more fully, further improving the solubility of air in water.

[0080] In this embodiment, one end of the first diverter 152 also has mounting end faces 157 located on both sides of the diverter portion 151, and the mounting end faces 157 are adapted to be connected with the wall surface of the inner cavity 111. The second diverter 153 also has mounting surfaces 158 located on both sides of the notch 154, and the mounting surfaces 158 are adapted to be connected with the wall surface of the inner cavity 111. The mounting end faces 157 of the first diverter 152 and the mounting surfaces 158 of the second diverter 153 are fixed to the wall surface of the inner cavity 111 by pasting. In other embodiments, snap-fit ​​structures can be provided on the first diverter 152 and the second diverter 153, and snap-fit ​​with corresponding structures on the wall of the inner cavity 111 to achieve fixed connection; or, under the condition that the manufacturing process allows, the diverter structure 150 can be integrally formed with the first shell 112.

[0081] The intersection of the first diverter surface 151a and the second diverter surface 151b is located on the extension line formed by the edge of the second diverter plate 153 at the notch 154, so as to avoid the diverter portion 151 protruding and interfering with the installation, and at the same time just corresponds to the inner end port setting of the input channel 122, ensuring the water flow segmentation effect. In this embodiment, the wall surface of the inner cavity 111 is in an arc shape, and the edge of the second diverter plate 153 is in an arc shape accordingly, and the extension line is also in an arc shape. It should be noted that the edge shape of the second diverter plate 153 is adapted to the shape setting of the wall surface of the inner cavity 111, and is not limited to an arc shape, and can be an oblique line, a right angle or a straight line.

[0082] In the present embodiment, the diverter structure 150 is formed in one piece, that is, the first diverter sheet 152 and the second diverter sheet 153 are an integral structure, do not need to be assembled, and basically intersect vertically, and have a better diverter effect. Of course, the first diverter sheet 152 and the second diverter sheet 153 can also intersect at other suitable angles, not limited to vertical. It should be noted that in other embodiments, the diverter structure 150 can be replaced by a porous medium, and the porous medium includes but is not limited to a sponge with a sparse texture. The diverter structure 150 can be directly set on the wall of the inner cavity 111 and cover the inner end of the input channel 122. When water flows through the micropores therein, the solubility of air can be increased. Moreover, its structure is simple and the cost is lower.

Among them, the first fluid pump 210 is connected to an input channel 122 of an input structure 120, and is used to input at least liquid into the inner cavity 111. In other words, the first fluid pump 210 can input water or a water-gas mixture into the inner cavity 111, and can also input water and air into the inner cavity 111 at the same time.

[0085] In order to improve the preparation efficiency of microbubble water, the microbubble generating device 200 further includes a second fluid pump 220 . The second fluid pump 220 is connected to the input channel 122 of another input structure 120 and is used to input air or oxygen into the inner cavity 111 .

[0086] In this embodiment, the first fluid pump 210 is a high-pressure water pump, which can pump high-pressure water into the inner cavity 111. The second fluid pump 220 is an air pump to replenish the air that is continuously dissolved in the water. It should be noted that in other embodiments, the first fluid pump 210 can be a vortex pump, which can simultaneously transport water and air into the inner cavity 111 without the need to set up the second fluid pump 220; or, the first fluid pump 210 is also a high-pressure water pump, and another input channel 122 of the microbubble generator 100 is directly connected to the atmosphere, and automatically intakes air without the need for air supply through an air pump; or, the first fluid pump 210 also uses a high-pressure water pump, and an air valve replaces the second fluid pump 220, and the air replenishment is controlled by the on-off control of the air valve.

[0087] In this embodiment, the working modes of the microbubble generating device 200 are not limited to the following two:

[0088] The first working mode: water is injected into the microbubble generator 100 through the first fluid pump 210, and pressure is provided to the microbubble generator 100, wherein the pressure should be greater than 2Bar, the greater the better, but considering both economy and effect, 3Bar to 5Bar is preferred. After water enters the microbubble generator 100, after passing through its diversion structure 150, the water flow is dispersed and decelerated, and fully contacts with the air in the inner cavity 111, allowing the air to dissolve into the water. The water dissolved with air is located at the bottom of the inner cavity 111, and then flows out through its throttling structure 140 to form microbubble water. After producing a certain amount of microbubble water or after a certain period of time, the first fluid pump 210 is turned off, and the second fluid pump 220 is turned on to replenish air in the inner cavity 111 and discharge water. The reason is that in this process, the air in the inner cavity 111 is consumed, and the inner cavity 111 is gradually filled with water, and air needs to be replenished. Among them, the size of the microbubble generator 100 can be calculated and determined according to demand.

[0089] The second working mode: the first fluid pump 210 and the second fluid pump 220 work simultaneously, and inject water and air into the microbubble generator 100 at a certain ratio; or, the first fluid pump 210 and the second fluid pump 220 are combined into one, and a pump that can simultaneously transport water and air is used instead, such as a vortex pump.

[0090] It should be noted that the microbubble generating device 200 of this embodiment can be applied to a surface cleaning device or a base station. The surface cleaning device can be a handheld cleaning device, a self-moving cleaning device, or an intelligent cleaning device.

[0091] When applied to surface cleaning equipment, the microbubble water generated by the microbubble generating device 200 can be directly supplied to its cleaning parts to perform deep cleaning on the cleaning parts (rolling brushes, mops or rags). At the same time, the microbubble water is used for surface cleaning, which can improve the cleaning effect, disinfect and sterilize, and enhance the user experience. The microbubble water can also be supplied to at least one of its clean water tank and sewage tank, and has the effect of disinfection and sterilization, reduces pollution, avoids bacterial growth, and enhances the user experience. The clean water tank can temporarily store microbubble water and supply it to the cleaning parts for use or spray it on the surface to be cleaned.

[0092] When applied to a base station, the microbubble water generated by the microbubble generating device 200 can be output to the cleaning tank of the base station through the clean water tank of the base station or directly supplied to the cleaning tank, thereby improving the self-cleaning effect of the cleaning parts of the surface cleaning equipment; it can also be supplied to the sewage tank of the base station, which has the effect of disinfection and sterilization, reduces pollution, avoids bacterial growth, and improves the user experience; it can also be supplied to the surface cleaning equipment through the interface, for example, the microbubble water can be injected into the clean water tank of the surface cleaning equipment.

[0093] Example 3

[0094] This embodiment provides a surface cleaning device, such as Fig. 9 As shown, in one embodiment, the surface cleaning device 300 includes a microbubble generator 100, a device water tank 310, a first fluid pump 320, a second fluid pump 330, and a cleaning member 340. The specific structure of the microbubble generator 100 refers to the above-mentioned embodiment 1. Since the surface cleaning device 300 of this embodiment adopts all the technical solutions of the above-mentioned embodiment 1, it also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiment 1, which will not be repeated here one by one.

[0095] The input end of the first fluid pump 320 is connected to the equipment water tank 310, and the output end of the first fluid pump 320 is connected to the input channel 122 of an input structure 120. The second fluid pump 330 is connected to the input channel 122 of another input structure 120. The output channel 132 of the output structure 130 can output microbubble water to the cleaning member 340, and perform deep cleaning on the cleaning member 340 to prevent dirt from accumulating on the cleaning member 340. At the same time, the cleaning member 340 uses microbubble water to clean the floor, which can improve the cleaning effect of the floor, disinfect and sterilize, and enhance the user experience.

[0096] In this embodiment, microbubble water is directly supplied to the cleaning member 340 after being generated, and the system is relatively simple. When the surface cleaning equipment is in normal use, the required clean water is generally less than 50 ml / min. In order to maintain the pressure in the microbubble generator 100, the size of the throttling channel 142 of the throttling structure 140 is designed to be very small, among which the aperture of the transition section 146 is less than 0.3 mm, and high manufacturing precision is required.

[0097] Specifically, the output structure 130 is connected to the water outlet structure of the surface cleaning device 300 through a pipeline. The water outlet structure is arranged corresponding to the cleaning component 340 and can spray or drip microbubble water onto the cleaning component 340.

[0098] In this embodiment, the first fluid pump 320 is a high-pressure water pump, and the second fluid pump 330 is an air pump.

[0099] In this embodiment, the surface cleaning device 300 is a handheld floor scrubber, and its cleaning member 340 is a roller brush. It should be noted that in other embodiments, the surface cleaning device 300 may be a handheld floor mopping machine or a handheld floor scrubbing machine, and its cleaning member 340 is a mop or a rag; the surface cleaning device 300 may also be a floor scrubbing robot, a floor mopping robot, a floor scrubbing robot, a sweeping and mopping robot, or other surface cleaning devices.

[0100] See also Fig.10 , Fig.10The schematic diagram of another embodiment of the surface cleaning device provided by Example 3 of the present invention is shown. Compared with the surface cleaning device 300 in the above embodiment, the output channel 132 of the output structure 130 of the microbubble generator 100 in this embodiment is connected to the device water tank 310, and the microbubble water is temporarily stored in the device water tank 310. Moreover, the microbubble water in the device water tank 310 can be supplied to the cleaning member 340 through the liquid supply mechanism of the surface cleaning device 300, instead of directly delivering the prepared microbubble water to the cleaning member 340 in the above embodiment.

[0101] Specifically, the first fluid pump 320 extracts clean water from the equipment water tank 310, and the microbubble water generated by the microbubble generator 100 is then transported back to the equipment water tank 310, converting the water in the entire equipment water tank 310 into microbubble water. Since the microbubble water is not stored for a long time, only a few minutes, the microbubble generator 100 needs to work intermittently to maintain the state of the microbubble water. The microbubble water can disinfect and sterilize the equipment water tank 310, avoid bacterial growth, and prevent the water from being deteriorated and smelly after being placed for a long time, thereby improving the user experience.

Since the base station 400 of this embodiment adopts all the technical solutions of the above embodiment 1, it also has all the beneficial effects brought by the technical solutions of the above embodiment 1, which will not be repeated here.

[0105] The input end of the first fluid pump 420 is connected to the base station water tank 410, and the output end of the first fluid pump 420 is connected to the input channel 122 of one input structure 120. The second fluid pump 430 is connected to the input channel 122 of another input structure 120.

The water outlet structure is set corresponding to the cleaning part, and microbubble water can be sprayed or dripped onto the cleaning part to perform deep cleaning on the cleaning part to avoid dirt accumulation on the cleaning part. At the same time, the cleaning part uses microbubble water to clean the ground, which can improve the cleaning effect of the ground and disinfect and sterilize. The surface cleaning device also includes a sewage tank.

The clean water tank temporarily stores microbubble water and transports the microbubble water to at least one of the cleaning part and the sewage tank through a liquid supply mechanism.

[0108] If the surface cleaning device requires a larger flow rate of microbubble water during self-cleaning, the size of the throttling channel 142 of the throttling structure 140 may be increased accordingly, or a plurality of smaller throttling channels 142 may be used to improve the efficiency of preparing microbubble water.

[0109] In this embodiment, the base station 400 is provided with a cleaning tank for self-cleaning of the cleaning parts. The output channel 132 of the output structure 130 is connected to the cleaning tank through a pipeline to supply microbubble water to the cleaning tank, thereby improving the self-cleaning effect of the cleaning parts and disinfecting the cleaning tank to avoid bacterial growth and prevent odor.

[0110] See also Fig.12 , Fig.12 The schematic diagram of another embodiment of the base station provided in Example 4 of the present invention is shown. Compared with the base station 400 in the above embodiment, the input channel 122 of an input structure 120 of the microbubble generator 100 of the base station 400 in this embodiment is used to input tap water, without the need to set the first fluid pump 420 of the base station 400 in the above embodiment. The base station 400 also includes an air valve 440, which is connected to the input channel 122 of another input structure 120 and replaces the second fluid pump 430 of the base station 400 in the above embodiment.

[0111] The base station 400 is directly supplied with household tap water, and the water pressure of the household tap water pipe is 1.5Bar-3.5Bar. The high pressure in the microbubble generator 100 is also provided by the tap water network. In this way, the first fluid pump 420 and the base station water tank 410 can be eliminated, saving costs and simplifying the structure.
