Description

Technical Field

[0001] This utility model relates to the field of kitchen and bathroom technology, and in particular to a microbubble generator, a water outlet pipe, and a toilet. Background Technology

[0002] A smart toilet is a sanitary ware equipped with functions such as washing, seat heating, warm air drying, and sterilization. Based on the washing function, there are different categories such as posterior wash and feminine wash. However, regardless of the type of washing, the washing water needs to have a good contact effect when it comes into contact with the user to reduce discomfort.

[0003] To reduce discomfort, related technologies offer two options: one is to adjust the water temperature to use warm water for washing; the other is to use sparkling water for washing. Sparkling water has stronger cleaning power, and its contact with the human body makes washing more comfortable and gentle. However, currently, smart toilets generate large bubbles in their sparkling water, but the number of bubbles is small, resulting in a poor user experience. Utility Model Content

[0004] The purpose of this invention is to provide a microbubble generator, a water outlet pipe, and a toilet, which reduces bubble splitting, increases the number of bubbles, forms denser and softer microbubble water, and improves the user experience.

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

[0006] A microbubble generator includes:

[0007] A barrel body having an inner cavity, the barrel body being provided with an inlet and an outlet communicating with the inner cavity, the inlet being used to inject gas and water, and the outlet being used to discharge bubble water from the inner cavity;

[0008] A cutting assembly, comprising a cutting element rotatably disposed within an inner cavity, wherein the water flow entering through the cavity inlet can drive the cutting element to rotate, and the cutting element is provided with a plurality of cutting holes;

[0009] A collision plug is disposed within the outlet cavity. At least one water outlet channel extending from the inner cavity to the outer periphery of the collision plug is provided, the water outlet channel communicating with the inner cavity. A collision channel is provided inside the collision plug, the inlet of the collision channel is connected to the inner cavity, and the outlet of the collision channel is connected between the inlet and the outlet of the water outlet channel.

[0010] In some embodiments, the cutting element is a filter screen, and the cutting assembly further includes a rotating shaft and a fixing frame. The rotating shaft is rotatably connected to the barrel body, the fixing frame is fixed to the rotating shaft, and the filter screen is fixed to the fixing frame.

[0011] In some embodiments, the outer periphery of the fixing frame is provided with a plurality of protrusions, and at least some of the two adjacent protrusions are misaligned.

[0012] In some embodiments, the water outlet channel is a spiral channel.

[0013] In some embodiments, the collision plug includes a column, a top plate, and spiral plates. The top plate is connected to one end of the column, and a plurality of spiral plates are arranged around the column. A spiral channel is formed between adjacent spiral plates. The collision channel is disposed on the column, and the top plate is provided with an outlet communicating with the spiral channel. The orthogonal projection of the outlet of the spiral channel onto the top plate partially overlaps with the outlet.

[0014] In some embodiments, the microbubble generator further includes a water outlet, the water outlet having a discharge channel, the water outlet being connected to the outlet cavity, and a turbulence block being provided in the discharge channel, with a gap between the turbulence block and the channel wall of the discharge channel.

[0015] In some embodiments, the discharge channel includes a first channel segment and a second channel segment, a first end of the first channel segment is connected to the outlet, the second channel segment is connected to the first channel segment, the second channel segment and the first channel segment are arranged at an angle, and the turbulence block is fixed in the first channel segment.

[0016] In some embodiments, the microbubble generator further includes a water inlet head, which includes a first pipe and a second pipe. One end of the first pipe is connected to the inlet port, and the other end of the first pipe is used to connect to a water source. The first pipe has a reduced diameter section, and the second pipe is connected to the reduced diameter section.

[0017] On the other hand, a water outlet pipeline is also provided, which includes an inlet valve and a microbubble generator as described above, wherein the inlet valve is connected to the inlet port.

[0018] Another option is a toilet that uses the water outlet pipe described above.

[0019] The beneficial effects of this utility model are:

[0020] Water and air are injected into the inner cavity through the inlet. The water flow drives the cutting element inside the cavity to rotate. During the rotation, the cutting element cuts the water flow through the cutting holes, increasing the number of bubbles and reducing their size. When the water flows out of the outlet, the outlet has a collision plug that separates the water flow. One part of the water flows out along the water outlet channel set on the outer periphery of the collision plug, while the other part of the water flows into the collision channel set inside the collision plug. It then collides with the water flow in the water outlet channel through the collision channel, which further reduces the size of the bubbles during the collision, increases the number of bubbles, and forms denser and softer microbubble water, improving the user experience.

[0043] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0044] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0045] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. 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.

[0046] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0047] like Figures 1 to 10 As shown, this utility model provides a microbubble generator, which includes a barrel body 1, a cutting component 2, and a collision plug 3. The barrel body 1 has an inner cavity 11, and the barrel body 1 is also provided with an inlet 12 and an outlet 13 communicating with the inner cavity 11. The inlet 12 is used to inject gas and water, while the outlet 13 is used to discharge bubble water from the inner cavity 11. The cutting component 2 includes a cutting element 21, which is provided with a plurality of cutting holes. The cutting element 21 is rotatably disposed in the inner cavity 11, and the water flow entering through the inlet 12 can drive the cutting element 21 to rotate. The collision plug 3 is disposed in the outlet 13, and at least one water outlet channel 31 is provided on the outer periphery of the collision plug 3, extending from the inner cavity 11 to the outer side of the inner cavity 11. The water outlet channel 31 communicates with the inner cavity 11. The collision plug 3 is provided with a collision channel 32, the inlet of which is connected to the inner cavity 11, and the outlet of which is connected between the inlet and outlet of the water outlet channel 31.

[0048] Water and air are injected into the inner cavity 11 through the inlet 12. The water flow drives the cutting element 21 in the inner cavity 11 to rotate. During the rotation, the cutting element 21 can cut the water flow through the cutting hole, increasing the number of bubbles and reducing the breakage of bubbles. When the water flows out from the outlet 13, the outlet 13 has a collision plug 3, which separates the water flow. Part of the water flows out along the water outlet channel 31 set on the outer periphery of the collision plug 3, while the other part of the water flows into the collision channel 32 set in the collision plug 3. The water flows into the collision channel 32 and collides with the water flow in the water outlet channel 31. The collision further reduces the breakage of bubbles, increases the number of bubbles, and forms denser and softer microbubble water, improving the user experience.

[0049] like Figure 2As shown, in some embodiments, the barrel 1 includes a barrel body 14 and a barrel lid 15. The upper end of the barrel body 14 is open, and the barrel lid 15 is placed over the opening of the barrel body 14 and fixed to the barrel body 14 by a detachable connection method, including but not limited to snap-fit, bolt connection, or plug-in connection, thereby facilitating subsequent maintenance of the cutting element 21 in the inner cavity 11. It is understood that a sealing ring is also sandwiched between the barrel lid 15 and the barrel body 14 for sealing. The inlet 12 is located on the side wall of the barrel body 14 and is closer to the bottom of the barrel body 14, while the outlet 13 is located on the barrel lid 15, thereby maximizing the time that water flows in the inner cavity 11, extending the cutting time of the cutting element 21, and further increasing the amount of bubbles.

[0050] like Figure 4 and Figure 5 As shown, in some embodiments, the cutting component 21 uses a filter screen, and the filter holes on the filter screen are the cutting holes. The cutting assembly 2 also includes a rotating shaft 22 and a fixing frame 23. The filter screen can be connected to the fixing frame 23 by means of snap-fit, plug-in, or adhesive. The fixing frame 23 is provided with plug-in holes, and the rotating shaft 22 is fixedly plugged into the plug-in holes, with both ends of the rotating shaft 22 extending out of the plug-in holes. The bottom wall of the barrel 14 and the barrel cover 15 are provided with rotation holes, and the opposite ends of the rotating shaft 22 are plugged into the rotation holes, so that the fixing frame 23 can be pushed to rotate in the inner cavity 11 under the action of water flow, thereby cutting the water in the inner cavity 11. In other alternative embodiments, the cutting component 21 can also be replaced by a fan blade, with a plurality of cutting holes distributed on the fan blade. For example, the pore size of the filter screen is 200-400 mesh, so that it can cut the water flow better. If the pore size is too small, it will easily block the water flow, and if the pore size is too large, it will weaken the cutting effect.

[0051] Furthermore, since the water in the inner cavity 11 flows outward due to centrifugal force when the filter screen rotates and cuts, several protrusions 24 are provided on the outer periphery of the fixed frame 23 to further improve the cutting effect on the outer water flow during the rotation of the fixed frame 23. This allows the protrusions 24 to agitate and cut the outer water flow, increasing the number of air bubbles. To enhance the agitation effect, at least some adjacent protrusions 24 are staggered.

[0052] In some embodiments, the impact plug 3 is fixed in the outlet 13 by an interference fit. It is understood that in other alternative embodiments, the impact plug 3 may also be fixed by a snap-fit ​​or other means.

[0053] Furthermore, in some embodiments, the water outlet channel 31 is a straight channel. However, in the current embodiment, such as... Figure 6 and Figure 7As shown, the water outlet channel 31 adopts a spiral channel. Compared with the collision of straight water flow, the spiral channel can utilize the rotational kinetic energy (angular momentum) of the water flow to better tear the water flow, thereby using more energy for the splitting of bubbles and forming more microbubbles. Specifically, the collision plug 3 includes a column 33, a top plate 34, and spiral plates 35. The top plate 34 is located at one end of the column 33 and is embedded in the outlet 13. In order for the water flow to pass through the top plate 34, the top plate 34 is provided with an outlet 36. Multiple spiral plates 35 are arranged around the column 33, and a spiral channel is formed between adjacent spiral plates 35. The spiral channel is connected to the outlet 36 one by one. The side of the spiral channel closer to the top plate 34 is the outlet, and the side farther from the top plate 34 is the inlet. The orthogonal projection of the outlet of the spiral channel onto the top plate 34 partially overlaps with the outlet 36. Thus, not only can the water flow in the collision channel 32 collide with the water flow in the spiral channel, but the water flow in the spiral channel can also collide with the top plate 34 at the outlet of the spiral channel, thereby further dispersing the bubbles at the top plate 34, increasing the number of bubbles, and reducing the size of the bubbles.

[0054] In other words, the water flow can collide at the outlet of the collision channel 32, then flow to the top plate 34 for another collision, and then flow out from the outlet 36. Through multiple collisions, the bubbles are broken up, making the bubbles denser.

[0055] like Figure 2 and Figure 8 As shown, in some embodiments, the microbubble generator 10 further includes a water outlet 4, which is provided with a discharge channel 41. The water outlet 4 is connected to the outlet 13, so that the water flow passing through the collision plug 3 flows into the water outlet 4 and flows out through the discharge channel 41. A turbulence block 5 is provided in the discharge channel 41. The water flow entering the discharge channel 41 will hit the turbulence block 5, thereby further splitting the bubbles. It can be understood that there is a gap between the turbulence block 5 and the channel wall of the discharge channel 41 to allow for flow.

[0056] like Figure 8 and Figure 9As shown, specifically, the discharge channel 41 includes a first channel segment 411 and a second channel segment 412. The second channel segment 412 is connected to the first channel segment 411. In this embodiment, the first end of the first channel segment 411 is connected to the outlet 13, and the second end of the first channel segment 411 is closed. The second channel segment 412 is connected to the middle of the first channel segment 411, so that the first channel segment 411 and the second channel segment 412 are set at an angle, for example, in a T-shape. A baffle block 5 is disposed in the first channel segment 411. The first end of the baffle block 5 is fixed to the second end of the first channel segment 411, and the second end of the baffle block 5 extends toward the outlet 13. In this embodiment, the baffle block 5 has multiple arc-shaped portions. One end of the multiple arc-shaped portions is connected, and the other end radiates outward from the connection point, so that the cross-section of the baffle block 5 is fan-shaped. When water flows into the first channel segment 411, it rotates and impacts the baffle block 5, further dispersing the air bubbles. In addition, the channel wall at the second end of the first channel section 411 is provided with multiple guide blocks 42. The multiple guide blocks 42 are distributed in a vortex shape around the turbulence block 5, thereby further inducing the water flow to rotate through the guide blocks 42, thereby enhancing the effect of rotational impact.

[0057] like Figure 1 and Figure 10 As shown, in some embodiments, the microbubble generator 10 further includes a water inlet head 6, which includes a first pipe 61 and a second pipe 62. One end of the first pipe 61 is connected to the inlet port 12, and the other end of the first pipe 61 is used to connect to a water source. In addition, the first pipe 61 has a reduced diameter section, and the second pipe 62 is connected to the reduced diameter section and is used to connect to an air pump. Thus, a mixture of water and gas is injected into the inlet port 12 through the water inlet head 6. When water is filled into the first pipe 61, the water flow will accelerate in the reduced diameter section, thereby forming a negative pressure. The second pipe 62 is connected to the reduced diameter section, thereby drawing in air entering the second pipe 62, which can reduce the problem of poor air intake and also reduce the power requirements of the air pump, saving costs.

[0058] This utility model also provides a water outlet pipe, which includes an inlet valve 20 and the aforementioned microbubble generator 10. The inlet valve 20 is connected to the inlet head 6, thereby connecting to the inlet port 12 to supply water to the inner cavity 11. Through the rotational cutting of the cutting piece 21, the impact at the collision plug 3, and the impact in the water outlet head 4, the bubble water is repeatedly dispersed, thereby forming a denser and softer microbubble water, improving the user experience.

[0059] This utility model also provides a toilet that uses the aforementioned water outlet pipe. Since the water outlet pipe is installed on the toilet, it may also include common components such as a heater 50, a water distribution valve 60, and a vacuum breaker 30; for example:

[0060] like Figure 11As shown, the water outlet pipeline includes a heater 50, a water distribution valve 60, a vacuum breaker 30, a water pump 40, a spray gun 70, and a microbubble generator 10. The water inlet of the vacuum breaker 30 is connected to the water outlet of the water distribution valve 60, the water inlet of the water pump 40 is connected to the water outlet of the vacuum breaker 30, the water inlet of the heater 50 is connected to the water outlet of the water pump 40, and the water inlet of the water distribution valve 60 is connected to the water outlet of the heater 50. The spray gun 70 has multiple outflow channels, and the water distribution valve 60 has multiple outflow ends. The water inlets of the multiple outflow channels of the spray gun 70 are connected to different outflow ends of the water distribution valve 60, so that water can be selectively supplied to different outflow channels of the spray gun 70 through the water distribution valve 60. For example, the spray gun 70 may include, but is not limited to, a self-cleaning channel and a cleaning channel, so that water washing is performed through the cleaning channel and self-cleaning is performed through the self-cleaning channel.

[0061] And depending on different needs, such as Figure 11 As shown, the microbubble generator 10 can be installed between the water distribution valve 60 and the heater 50, so that microbubble water can be directly circulated through the cleaning channel to form microbubble water washing. Alternatively, a bubble nozzle 90 can be connected to one of the outlets of the water distribution valve 60, so that ordinary water washing is performed through the cleaning channel, and microbubble water washing is performed through the bubble nozzle 90.

[0062] Of course, such as Figure 13 As shown, the microbubble generator 10 can also be installed at one of the outlet ends of the water distribution valve 60. The spray gun 70 also has a microbubble channel, so that the outlet 13 of the microbubble generator 10 is connected to the microbubble channel of the spray gun 70, thereby forming ordinary water cleaning through the cleaning channel and microbubble water washing through the microbubble channel, improving the adaptability to the inner pipe range; or as... Figure 12 As shown, the microbubble generator 10 is installed at one of the outlet ends of the water distribution valve 60, and an additional bubble nozzle 90 is connected to the microbubble generator 10.

[0063] In addition, a ceramic lubricating tube 80 can be installed in the water outlet pipeline. The ceramic lubricating tube 80 is connected to one of the water outlet ends of the water distribution valve 60, so that ceramic lubrication operation can be performed.

[0064] It is understood that the above-mentioned water outlet pipe is only one type of connection, and in other alternative embodiments, the connection positions of each component can be changed according to different water outlet requirements.

[0065] Of course, the water outlet pipe can also be used on other devices that require aerated water, such as shower heads and faucets.

[0066] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
