Description

Technical Field

[0001] The utility model relates to the technical field of pipeline splicing, and specifically relates to a pipeline joint. Background Art

[0002] A pipeline joint is a connecting fitting used at the end of a pipeline or for connecting pipelines. Common usage locations include faucets, water pipes, sewage channel structures, water inlet and outlet channel structures, etc. By designing a narrowing structure in the middle of the pipeline joint, a certain amount of microbubbles can be generated in the water flow. However, the quality of existing joints for generating microbubbles on the market varies, which will directly affect the quality of microbubble generation. In addition, (as Figure 7 shown) existing joints on the market generally adopt a split structure for on-site installation, with many accessory processes, cumbersome installation, and large material losses in split production, which is not conducive to reducing production costs and product installation and use.

[0003] In view of the above deficiencies, we need to develop a pipeline joint to meet the usage needs of the majority of users. Content of the Utility Model

[0004] In view of the problems mentioned above that existing pipeline joints have many accessory processes, cumbersome installation, large material losses in production, and are not conducive to reducing production costs, the technical solution adopted by the utility model to solve its technical problems is:

[0005] A pipeline joint includes a hollow and through main body. The inside of the main body has a channel structure for liquid to pass through. The channel structure includes a first channel port, a second channel port, and a third channel port that are sequentially arranged and communicate with the outside. The diameter a of the first channel port and the diameter c of the third channel port are both larger than the diameter b of the second channel port. The outside of the main body has a recessed portion that is recessed towards the channel structure.

[0006] Further, the first channel port communicates with the outside through the first interface of the main body, the third channel port communicates with the outside through the second interface of the main body, the diameter e of the first interface is larger than the diameter a of the first channel port, and the diameter f of the second interface is larger than the diameter c of the third channel port.

[0007] Further, the position of the recessed portion close to the first interface has a first connection portion for connecting with the surface of the main body, the position of the recessed portion close to the second interface has a second connection portion for connecting with the surface of the main body, and the first connection portion and the second connection portion are respectively smoothly connected to the outer surface of the main body.

[0008] Further, an arc surface structure that bends toward the channel structure is provided between the first connecting portion and the second connecting portion. The arc surface structure smoothly connects the first connecting portion and the second connecting portion. The circular arc transition radius j of the first connecting portion is smaller than the circular arc transition radius k of the second connecting portion.

[0009] Further, the outer surface of the main body has an anti-slip structure. The anti-slip structure has a plurality of anti-slip lines that are circumferentially arranged around the central axis of the main body at intervals. The anti-slip lines are recessed toward the inside of the main body in a long strip rounded groove structure.

[0010] Further, the channel structure adopts a Venturi tube structure. The Venturi tube structure is sequentially provided with an inlet section s, a contraction section x, a throat y, and a diffusion section z. The inlet section s is located at the first channel opening. The throat y is located at the second channel opening. The contraction section x is located between the first channel opening and the second channel opening. The diffusion section z is located between the second channel opening and the third channel opening.

[0011] Further, a straight conical surface structure is adopted between the first channel opening and the second channel opening, and / or a straight conical surface structure is adopted between the third channel opening and the second channel opening. The inner side surfaces of the channel structure gradually narrow from the first channel opening and the third channel opening toward the second channel opening.

[0012] Further, it further includes a flow-through pipe fitting that is detachably connected to the main body. The channel structure is located on the flow-through pipe fitting. The inside of the main body has a hollow and through-flow structure. The through-flow structure has an in-pipe installation portion for installing the flow-through pipe fitting. The outer side of the flow-through pipe fitting has an out-of-pipe installation portion for connecting to the in-pipe installation portion.

[0013] Further, the out-of-pipe installation portion is located at a position on the outer side of the flow-through pipe fitting close to the first channel opening. The in-pipe installation portion is located at a position on the through-flow structure close to the first interface.

[0014] Further, the through-flow structure has an avoidance portion for avoiding the installation of the flow-through pipe fitting. The avoidance portion is located at a position on the through-flow structure close to the second interface. The diameter m of the avoidance portion is larger than the diameter n of the in-pipe installation portion.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. The present utility model directly forms a channel structure (i.e., a narrowing structure) that can generate microbubbles inside the main body of the pipe joint. Compared with the split structure of traditional pipe joints, it can save the number of fittings and fitting processes, reduce processing steps, make installation and processing more convenient, improve production efficiency. By designing a recess on the outer side of the main body, it can also reduce the amount of material required for overall processing, reduce the overall weight, lower production costs, and achieve an environmental protection effect. On this basis, the recess can also facilitate the user to hold and take by hand, making it convenient for workers to install and disassemble, and improving the maintenance and replacement efficiency.

Through a number of circumferentially arranged and spaced anti-slip lines, it is convenient for users or workers to perform a labor-saving screwing action during installation and disassembly, effectively increasing the friction force of the pipe joint on the hand. On this basis, the anti-slip lines adopt a long strip rounded groove structure that is recessed towards the inside of the main body. While improving the anti-slip friction force, the smooth transition of the rounded corners is used to improve the force-bearing effect of hand holding, making the touch of the user's or worker's hand when contacting the anti-slip lines more comfortable, and avoiding the angular feeling of sharp corners stabbing the hand and causing uncomfortable touch.

[0018] 3. The present utility model further includes a flow-through pipe fitting detachably connected to the flow-through structure inside the main body. The channel structure is independently arranged on the flow-through pipe fitting, enabling the pipe joint to be freely replaced with flow-through pipe fittings of different channel structures according to the needs of users or workers, expanding the application range of the pipe joint. There is no need to disassemble and replace the whole, and only need to disassemble and replace the flow-through pipe fitting to change the type of the channel structure, which is convenient for users or workers to use.

[0026] The following will describe in detail the implementation manners of the present utility model with reference to the accompanying drawings.

[0027] Optionally, in some embodiments, the main body 100 can be made of one of materials such as metal, plastic, wood, stone, glass, ceramic, etc. Preferably, the main body 100 is made of copper in metal. Copper has excellent corrosion resistance, can remain stable in various environments, is not easy to rust or be corroded, and extends the service life of the pipe joint. Copper has good mechanical strength and toughness, can withstand the pressure change in the pipe without being easily broken. In addition, copper has natural antibacterial properties, can effectively inhibit the growth of bacteria, and has a protective effect on water quality, which is particularly important when applied to drinking water pipes. Copper is easy to cut, weld and form, making it highly convenient in the production and installation process. At the same time, copper is a recyclable material with good environmental protection performance, meeting the requirements of sustainable development.

[0028] On this basis, optionally, the flow-through pipe fitting 200 can also be made of the same material as the main body 100.

[0029] Embodiment 1:

[0030] As Figures 1 to 6 shown, a pipe joint includes a hollow and through main body 100. The main body 100 is the base carrier of the pipe joint and the main structural body of the overall structure of the pipe joint. The inside of the main body 100 has a channel structure 1 for liquid to pass through and generate microbubbles. In this embodiment, the channel structure 1 is integrally formed with the main body 100. Compared with the traditional split joint structure, it can save the number of fittings and fitting processes. The number of fittings is reduced from the traditional 2 or 4 required pieces to 1 integrated piece, and the processing steps can also be reduced. There is no need for separate processing and separate blanking. The pipe body and the channel structure can be directly processed from the same block to achieve the same water outlet effect. The integrally formed structure is more durable in terms of use stability and durability compared with the split structure. The structure is more stable and not easy to deform or damage, and can withstand greater pipe flow pressure. On this basis, reducing the number of fittings makes the installation by users or the processing by workers more convenient and improves production efficiency.

[0031] More specifically, the channel structure 1 includes a first channel opening 11, a second channel opening 12, and a third channel opening 13 which are sequentially arranged and connected to the outside. The diameter a of the first channel opening 11 is larger than the diameter b of the second channel opening 12, and the diameter c of the third channel opening 13 is also larger than the diameter b of the second channel opening 12, forming a channel structure 1 with widened ends and narrowed in the middle. The channel structure 1 adopts such a design that a Venturi effect can be generated when water flows through, so that the original water flows into the channel structure 1 from the first channel opening 11 and then passes through the narrowed portion (i.e., the second channel opening 1 2), it can absorb air and mix to produce microbubbles, which are a general term for fine bubbles, micron bubbles and ultrafine bubbles, with microns (μm) as the unit. Among them, small bubbles with a diameter greater than 100μm in water are microbubbles, small bubbles with a diameter greater than 1μm and less than 100μm in water are micron bubbles, and small bubbles with a diameter less than 1μm in water are ultrafine bubbles. When water flows through the channel structure 1, a large number of microbubbles can be generated by the Venturi effect. With the help of specific tools or accessories, ultrafine bubbles can also be generated.

[0032] In actual use, ordinary bubbles rise quickly and disappear immediately after bursting on the water surface, while micron bubbles rise very slowly, and the gas in the bubbles disappears in the water after being completely dissolved, while nanobubbles not only do not float to the water surface, but can also float in the water for a long time, continuously performing Brownian motion, thereby producing technical effects such as cleaning, sterilization, deodorization, and protection. Among them, microbubbles can adsorb and peel off dirt to achieve cleaning, physically squeeze out details through microbubbles to inhibit the reproduction of details and achieve sterilization, microbubbles and cleaning ingredients enter the fiber gaps of the laundry together to achieve deodorization, and microbubbles can improve and maintain the pipeline environment to achieve protection.

[0033] More specifically, the outer side of the main body 100 has a recessed portion 2 recessed toward the channel structure 1. During the production process, the main body 100 can save a considerable part of its volume through the recessed portion 2, thereby saving production materials. In the wide application of mass production, it can generate considerable economic benefits, and reducing materials can achieve certain environmental protection effects. On this basis, the recessed portion 2 reduces the amount of materials required for the overall processing of the main body 100, reduces the overall weight, facilitates transportation and loading and unloading, and reduces production costs. In addition, the recessed portion 2 can also facilitate users to hold and take it, facilitate workers to install and disassemble, and improve maintenance and replacement efficiency.

[0034] As another embodiment of Embodiment 1, the main body 100 is made of copper material among metals. The copper material has excellent corrosion resistance, can remain stable in various environments, is not easy to rust or be corroded, and extends the service life of the pipe joint. The copper material has good mechanical strength and toughness, can withstand the pressure changes inside the pipe without being easily broken. In addition, the copper material has natural antibacterial properties, can effectively inhibit the growth of bacteria, and has a protective effect on water quality, which is particularly important when applied to drinking water pipes. The copper material is easy to cut, weld and form, making it highly convenient during the production and installation process. At the same time, the copper material is a recyclable material with good environmental protection performance, meeting the requirements of sustainable development.

[0035] As another embodiment of Embodiment 1, the first channel port 11 communicates with the outside through the first interface 101 of the main body 100, and the third channel port 13 communicates with the outside through the second interface 102 of the main body 100. Among them, the first interface 101 is the access port of the main body 100 for actively connecting other pipes or faucets. The first interface 101 can adopt one of the connection methods such as threaded connection, snap connection, plug - and - play connection, etc. Preferably, in this embodiment, the outer side of the first interface 101 has an external thread. The second interface 102 is the outlet port of the main body 100 for being passively connected by other pipes or faucets. The second interface 102 can adopt one of the connection methods such as threaded connection, snap connection, plug - and - play connection, etc. Preferably, in this embodiment, the inner side of the second interface 102 has an internal thread;

[0036] More specifically, the diameter e of the first interface 101 is larger than the diameter a of the first channel port 11, and the diameter f of the second interface 102 is larger than the diameter c of the third channel port 13, so as to facilitate the formation of the channel structure 1. Moreover, the wall thickness of the channel structure 1 is also larger than the wall thickness of the first interface 101 or the second interface 102 to improve the ability of the channel structure 1 to withstand the pipe flow pressure.

[0037] As another embodiment of Embodiment 1, a straight conical surface structure formed by linear rotation is adopted between the first channel port 11 and the second channel port 12, and a straight conical surface structure is adopted between the third channel port 13 and the second channel port 12. The inner surface of the channel structure 1 gradually narrows from the first channel port 11 and the third channel port 13 towards the second channel port 12.

[0038] As another embodiment of Embodiment 1, a straight conical surface structure formed by linear rotation is adopted between one of the first channel port 11 and the third channel port 13 and the second channel port 12, and a curved conical surface structure formed by circular arc curve rotation is adopted between the other of the first channel port 11 and the third channel port 13 and the second channel port 12. The inner surface of the channel structure 1 gradually narrows from the first channel port 11 and the third channel port 13 towards the second channel port 12.

[0039] Embodiment 2:

[0040] Based on Embodiment 1, as Figures 2 to 6 shown by a pipe joint, at the position where the recessed part 2 is close to the first interface 101, there is a first connecting part 21 for connecting with the surface of the main body 100. At the position where the recessed part 2 is close to the second interface 102, there is a second connecting part 22 for connecting with the surface of the main body 100. Among them, the first connecting part 21 is the intersection connection between the recessed part 2 and the outer wall of the main body 100. The first connecting part 21 can form a connecting position in the way of a chamfered right angle or a chamfered arc angle. Preferably, the first connecting part 21 adopts a chamfered arc angle structure to smoothly connect with the outer wall of the main body 100. The second connecting part 22 is the intersection connection between the recessed part 2 and the outer wall of the main body 100. The second connecting part 22 can form a connecting position in the way of a chamfered right angle or a chamfered arc angle. Preferably, the second connecting part 22 adopts a chamfered arc angle structure to smoothly connect with the outer wall of the main body 100.

[0041] More specifically, the position between the first connecting part 21 and the second connecting part 22 can be connected by a straight line and / or a curve according to actual needs to form the recessed shape of the recessed part 2, so as to improve the comfort of holding and taking by the user's or worker's hand.

[0042] More specifically, the first connecting part 21 and the second connecting part 22 can respectively adopt different chamfer structures, or can also adopt the same chamfer structure to form more pipe joint styles. In this embodiment, the first connecting part 21 and the second connecting part 22 adopt the same chamfer structure, but the sizes of the chamfers are different, so as to improve the comfort of holding and taking by the user's or worker's hand.

[0043] As another embodiment of Embodiment 2, the first connecting part 21 and the second connecting part 22 respectively adopt different chamfer structures. One of the first connecting part 21 and the second connecting part 22 adopts a chamfered right angle structure, and the other of the first connecting part 21 and the second connecting part 22 adopts a chamfered arc angle structure to form more pipe joint styles for users to select and purchase.

[0044] As another embodiment of Embodiment 2, there is a curved surface structure 23 that bends toward the channel structure 1 between the first connecting portion 21 and the second connecting portion 22. The curved surface structure 23 is a concave shape formed between the first connecting portion 21 and the second connecting portion 22. By using the curved surface structure 23 that bends inward, the comfort of the user's or worker's hand when holding and taking can be further improved. The curved surface structure 23 smoothly connects the first connecting portion 21 and the second connecting portion 22, so that during the process of the user's or worker's hand holding and taking, the angular feeling like sharp corners stabbing the hand can be avoided, thus improving the comfort of holding and taking. On this basis, the arc transition radius j of the first connecting portion 21 is smaller than the arc transition radius k of the second connecting portion 22, so that the whole recess 2 is closer to the position of the first interface 101. When the second channel opening 12 is located in the middle of the main body 1, the recess 2 can be misaligned to avoid the weak position of the channel structure 1, thereby improving the flow stability of the overall structure of the main body 100.

[0045] Embodiment 3:

[0046] Based on any of the above embodiments, as Figures 1 to 6 shown, for a pipe joint, the outer surface of the main body 100 has an anti-slip structure 3. The anti-slip structure 3 is located on the outer surface of the main body 100 near the second interface 102. By providing the anti-slip structure 3 that is convenient for the hand to hold and twist on the surface of the pipe joint, the friction between the surface of the pipe joint and the hand can be effectively increased. The anti-slip structure 3 has a number of anti-slip lines 31 that are circumferentially arranged around the central axis of the main body 100 and are evenly spaced, which is convenient for the user or worker to perform a labor-saving twisting action during installation and disassembly. On this basis, the anti-slip lines 31 adopt a long strip rounded groove structure that is recessed toward the inside of the main body, deepening the texture of the anti-slip lines 31. At the same time, a rounded fillet is used at the connection intersection of the anti-slip lines 31 and the outer surface of the main body 1 to provide a more comfortable holding and twisting feel. During the twisting process, the user or worker will not be affected by the discomfort of the sharp chamfer, and while improving the anti-slip friction, the smooth transition of the rounded fillet is used to improve the force effect of the hand holding, so that the touch of the user's or worker's hand when contacting the anti-slip lines can be more comfortable, avoiding the angular feeling like sharp corners stabbing the hand and causing touch discomfort. On this basis, the design of the long strip groove can increase the contact area between the hand and the anti-slip structure 3, further improving the twisting stability and comfort.

[0047] As another embodiment of Example 3, if the direction of the anti-slip pattern 31 is the same as the rotation direction of the hand (that is, the direction of the anti-slip pattern 31 is arranged and extends along the circumference of the main body 100), the friction generated by the anti-slip pattern 31 on the hand will be greatly reduced, which can easily cause slipping or half the effort with twice the force. Therefore, this embodiment further restricts the direction of the anti-slip pattern 31 to strengthen the friction between the hand and the anti-slip pattern 31. More specifically, the direction of the anti-slip pattern 31 is the same as the axial direction of the main body 100, that is, when the user or the worker manually screws, the rotation direction of the hand can be perpendicular to the direction of the anti-slip pattern 31 to strengthen the friction generated by the anti-slip pattern 31 on the hand.

[0048] Embodiment 4:

[0049] Based on any of the above embodiments, Figure 2 A pipe joint is shown, in which the channel structure 1 adopts a Venturi tube structure. The Venturi tube structure is a pipe channel structure made by utilizing the Venturi effect. The Venturi tube structure is sequentially provided with an inlet section s, a contraction section x, a throat y and a diffusion section z, wherein the inlet section s is an inlet position for liquid to flow in, the contraction section x is a narrowing extension section for producing a narrowing and compression effect after the liquid flows in, the throat y is a narrowing position with the smallest diameter after the liquid flows in, and the diffusion section z is a widening extension section for the liquid to gradually widen and diffuse after flowing into the narrowing position.

[0050] More specifically, the inlet section s is located at the first channel opening 11 of the main body 100 near the first joint 101, the throat y is located at the second channel opening 12 near the middle of the main body 100, the contraction section x is located between the first channel opening 11 and the second channel opening 12, and the contraction section x can adopt a straight cone surface formed by a straight line rotation or a curved cone surface formed by a circular arc rotation as a contraction structure. Preferably, the contraction section x adopts a straight cone surface formed by a straight line rotation as a contraction structure, which can effectively cause the water flow to collide to form a large number of microbubbles. The diffusion section z is located between the second channel opening 12 and the third channel opening 13, and can adopt a straight cone surface formed by a straight line rotation or a curved cone surface formed by a circular arc rotation as a contraction structure. Preferably, the diffusion section z adopts a straight cone surface formed by a straight line rotation as a contraction structure, which can effectively cause the water flow to collide to form a large number of microbubbles.

[0051] Embodiment 5:

[0052] On the basis of any of the above embodiments, a pipe joint also includes a flow pipe 200 detachably connected to the main body 100, and the channel structure 1 can be independently arranged on the flow pipe 200, so that the pipe joint can replace the flow pipe 200 of different channel structures 1 at will according to the needs of users or workers, thereby improving the use and adaptation range of the pipe joint. There is no need to disassemble and replace the entirety, and the type of the channel structure can be changed by disassembling and replacing the flow pipe, which is convenient for users or workers to use.

[0053] More specifically, inside the main body 100, there is a flow-through structure 4 for accommodating and installing the flow-through pipe fitting 200. The flow-through structure 4 is hollow and penetrates through, and is respectively connected to the first joint 101 and the second joint 102. The flow-through structure 4 has an inner pipe installation part 41 for installing the flow-through pipe fitting 200. On the outer side of the flow-through pipe fitting 200, there is an outer pipe installation part 201 for connecting to the inner pipe installation part 41. Among them, the inner pipe installation part 41 can adopt one of the connection methods such as threaded connection, snap connection, plug-and-play connection, etc. Preferably, the inner pipe installation part 41 uses internal threads as the method for connecting to the outer pipe installation part 201. The outer pipe installation part 201 can adopt one of the connection methods such as threaded connection, snap connection, plug-and-play connection, etc. Preferably, the outer pipe installation part 201 uses external threads as the method for connecting to the inner pipe installation part 41. The self-locking characteristic of the threads can not only strengthen the connection stability but also provide strong position stability, reducing the influence of the installation of the flow-through pipe fitting 200 by the impact of water flow.

[0054] More specifically, the outer pipe installation part 201 is located at a position on the outer side of the flow-through pipe fitting 200 close to the first channel opening 11, and the inner pipe installation part 41 is located at a position on the flow-through structure 4 close to the first interface 101.

[0055] More specifically, on the basis of removing the flow-through pipe fitting 200, the pipe joint can also form a Venturi effect through the flow-through structure 4, that is, the first joint 101 is used as the inlet section s, the section between the first joint 101 and the inner pipe installation part 41 is used as the contraction section x, the inner pipe installation part 41 is used as the throat y, and the second joint 102 is used as the diffusion section z, so that a large number of microbubbles are generated in the passing water flow.

[0056] As another embodiment of Embodiment 5, the channel structure 1 on the flow-through pipe fitting 200 can also adopt a Venturi tube structure. Among them, the inlet section s is located at the first channel opening 11 of the flow-through pipe fitting 200, the throat y is located at the second channel opening 12 of the flow-through pipe fitting 200 close to the middle position, the contraction section x is located between the first channel opening 11 and the second channel opening 12. The contraction section x can adopt a straight conical surface formed by linear rotation or a curved conical surface formed by circular arc curve rotation as the contraction structure. Preferably, the contraction section x adopts a straight conical surface formed by linear rotation as the contraction structure, which can effectively make the water flow collide to form a large number of microbubbles. The diffusion section z is located between the second channel opening 12 and the third channel opening 13, and can adopt a straight conical surface formed by linear rotation or a curved conical surface formed by circular arc curve rotation as the contraction structure. Preferably, the diffusion section z adopts a straight conical surface formed by linear rotation as the contraction structure, which can effectively make the water flow collide to form a large number of microbubbles.

[0057] As another embodiment of Embodiment 5, the outer pipe mounting portion 201 is located outside the flow-through pipe fitting 200 near the first channel opening 11, and the inner pipe mounting portion 41 is located at the position of the flow-through structure 4 near the first interface 101. With such a structure, the position for firm connection can be set near the inlet position of the water flow impact, making the connection more stable and durable.

[0058] As another embodiment of Embodiment 5, the flow-through structure 4 has an avoidance portion 42 for avoiding the installation of the flow-through pipe fitting 200. The avoidance portion 42 is located at the position of the flow-through structure 4 near the second interface 102, and the diameter m of the avoidance portion 42 is larger than the diameter n of the inner pipe mounting portion 41. With such a structure, the avoidance portion 42 can be utilized as the diffusion section z of the flow-through structure 4 to form a better Venturi effect to generate more and finer microbubbles.

[0059] As Figures 1 to 3 shown, one of the specific embodiments of the present utility model is as follows:

[0060] The main body 100 and the channel structure 1 of this embodiment are integrally formed.

[0061] During use, the user or worker can hold the pipeline joint by grasping the recessed portion 2. The main body 100 can be detachably connected to other pipelines or faucets through the first joint 101 by hand contacting and screwing the anti-slip lines 31 of the anti-slip structure 3. After the water flow enters from the first joint 101, it flows through the first channel opening 11, the second channel opening 12, and the third channel opening 13. During the flowing process, affected by the Venturi effect, when the original water flow enters the channel structure 1 from the first channel opening 11 and passes through the narrowing part (i.e., the second channel opening 12), it can adsorb air and mix to generate microbubbles, and finally flows out through the second joint 102 to form a water flow rich in microbubbles.

[0062] On this basis, other pipelines or faucets can also be connected to the main body 100 through the second interface 102, so that the main body 100 forms an intermediate connecting adapter to achieve the effect of pipeline connection.

[0063] The second specific embodiment of the present utility model is as follows:

[0064] On the basis of the first specific embodiment, the channel structure 1 adopts a Venturi tube structure to further improve the quality and quantity of microbubble formation. The inlet section s is located at the first channel opening 11 of the main body 100 close to the first joint 101, the throat y is located at the second channel opening 12 of the main body 100 close to the middle position, the contraction section x is located between the first channel opening 11 and the second channel opening 12, and the contraction section x adopts a straight conical surface formed by linear rotation as the contraction structure, which can effectively make the water flow collide to form a large number of microbubbles. The diffusion section z is located between the second channel opening 12 and the third channel opening 13, and the diffusion section z adopts a straight conical surface formed by linear rotation as the contraction structure, which can effectively make the water flow collide to form a large number of microbubbles.

[0065] As Figures 4 to 6 shown, the third specific embodiment of the present utility model is as follows:

[0066] On the basis of the first or second specific embodiment, the main body 100 and the flow-through pipe fitting 200 adopt a detachable connection structure. The channel structure 1 is located on the flow-through pipe fitting 200. During use, the flow-through pipe fitting 200 is installed in the pipe installation part 41 of the main body 100 in advance. The user or worker can hold the main body 100 by grasping the recessed part 2.
