[0007] In one embodiment, the first mixing element is further provided with a grille portion located at the downstream end of the water inlet, and the grille portion is provided with a plurality of water holes.

[0008] In one embodiment, the air inlet channel extends into the water inlet channel, and is further provided with a water flow channel penetrating the side wall of the air inlet channel. At least a portion of the water from the water inlet channel flows through the water flow channel and is then discharged to the discharge channel. The intersection of the air inlet channel and the water flow channel forms the air-water intersection chamber. The water inlet channel is connected to the air-water intersection chamber through the water flow channel. The water flow in the water flow channel forms a suction force on the gas, thereby promoting the gas to enter the air-water intersection chamber through the air inlet channel.

[0014] The beneficial effects of the utility model are:

[0015] 1. The water inlet channel and the air inlet channel are respectively connected to the gas-water intersection chamber. The gas and water are mixed through the gas-water intersection chamber to form sterilizing water. The bathroom equipment uses this gas-water dissolution structure to eliminate bacteria in the bathroom water and provide sterilizing water with sterilization function to the outside, thereby sterilizing the objects being flushed (human body, toilet, sink or floor, etc.) to prevent bacteria in the water from causing harm to the human body.

[0016] 2. A diameter reduction structure and an air inlet are set in the gas-water intersection chamber.

[0017] 3. The diameter setting of the water inlet section can gradually increase the speed of water flowing in the water inlet section and the water pressure. The flow rate and pressure of water can be controlled by changing the diameter of the water inlet section. The structure is simple and easy to implement. The diameter setting of the mixing section reduces the pressure and flow rate of the sterilizing water, giving the sterilizing water more time to mix and make the sterilizing water more uniform.

[0018] 4. The grille portion arranged at the downstream end of the water inlet section can further reduce the diameter of the downstream end of the water inlet section, further improve the effect of the diameter reduction structure on increasing the flow rate and pressure of water, further increase the suction force on the gas, thereby further increasing the gas concentration in the sterilization water and further improving the sterilization effect.

[0019] 5. The dissolution zone further reduces the flow rate of the sterilizing water and fully mixes it therein. The second mixing element arranged in the dissolution zone can block the sterilizing water through its porous structure design, further prolonging the time that the sterilizing water stays in the dissolution zone, so that the gas can be better dissolved in the water.

[0020] 6. The extended water channel extends into the air inlet channel and penetrates the side wall of the air inlet channel, so that the water flow can form suction on the gas in the air inlet channel, promote the sterilization gas to enter the gas-water intersection chamber and dissolve with water, increase the gas concentration in the sterilization water, and ensure the sterilization effect.

[0021] 7.

[0045] To further illustrate various embodiments, the present invention is provided with accompanying drawings. These drawings form part of the disclosure of this invention and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, those skilled in the art will understand other possible implementations and the advantages of this invention. The components in the figures are not drawn to scale, and similar reference numerals are generally used to represent similar components.

[0046] Example 1

[0047] See Figures 1 to 4 As shown, the utility model discloses an air-water dissolution structure 10, comprising a water inlet channel 1, an air inlet channel 2 and a discharge channel 3. The water inlet channel 1 and the air inlet channel 2 are respectively connected to the air-water intersection chamber 4. The water inlet channel 1 is used to supply water to flow through it and enter the air-water intersection chamber 4. The air inlet channel 2 is used to supply gas to flow through it and enter the air-water intersection chamber 4. The gas is a sterilizing gas with a sterilization function. The air-water intersection chamber 4 is used to supply water and gas to mix to form sterilizing water. The discharge channel 3 is used to discharge the sterilizing water.

[0048] The sterilizing gas in this example is ozone, which can dissolve in water to form sterilizing water with active oxygen ions. In other embodiments, the sterilizing gas can also be chlorine or other gases with sterilizing function, which dissolve in water to form sterilizing water with hypochlorite ions.

[0049] The water inlet channel 1 and the air inlet channel 2 are respectively connected to the air-water intersection chamber 4, through which the gas and water are mixed to form sterilizing water. The bathroom equipment uses the air-water dissolving structure 10 to eliminate bacteria in the bathroom water and provide sterilizing water with sterilization function to the outside, thereby sterilizing the objects being flushed (human body, toilet, sink or floor, etc.) to prevent bacteria in the water from causing infection and harm to the human body.

[0050] See Figures 2 to 4 As shown, a diameter-reducing structure 41 connected to the water inlet channel 1 and an air inlet 42 connected to the air inlet channel 2 are provided in the air-water intersection chamber 4. In the direction of water flow, the air inlet 42 is located downstream of the diameter-reducing structure 41. The diameter-reducing structure 41 reduces the diameter of the water inlet channel 1 so that the water forms a suction force on the gas, thereby promoting the gas to enter the air-water intersection chamber 4 through the air inlet.

[0051] A reducing structure 41 and an air inlet 42 are provided in the air-water intersection chamber 4. The reducing structure 41 accelerates the water, forms suction on the gas in the air inlet channel 2, and promotes the gas to enter the air-water intersection chamber 4 through the air inlet 42, thereby increasing the gas concentration in the sterilizing water and ensuring the sterilization effect.

[0052] Continue reading Figures 2 to 4 As shown, the water inlet channel 1, air inlet channel 2, outlet channel 3, and air-water intersection chamber 4 are interconnected cavities formed within the body 5. A first mixing element 6 is disposed within the air-water intersection chamber 4. The first mixing element 6 includes an inlet section 61, which includes an upstream inlet end 611 and a downstream inlet end 612, both located along the water flow direction. The diameter of the upstream inlet end 611 is larger than the diameter of the downstream inlet end 612, and the diameter of any position on the inlet section 61 is no smaller than the diameter of any position downstream thereof. Thus, the inlet section 61 forms part of the reduced diameter structure 41. The first mixing element 6 also includes a mixing section 62, located downstream of the inlet section 61. The diameter of any position on the mixing section 62 is no larger than the diameter of any position downstream thereof. The air inlet 42 is disposed on the sidewall of the mixing section 62. The mixing section 62 includes an upstream mixing end 621 and a downstream mixing end 622, both located along the water flow direction. The diameter gradually increases from the upstream mixing end 621 to the downstream mixing end 622. The first mixing element 6 is further provided with a grille portion 63 located at the downstream end 612 of the water inlet. The grille portion 63 is provided with a plurality of water holes 631 , so that the grille portion 63 further reduces the water flow path.

[0053] More specifically, the first mixing element 6 of this example is roughly an hourglass-like structure with a small middle and large ends. The water inlet section 61 can be divided into two sections along the direction of water flow. The first section is close to the upstream end 611 of the water inlet, and the inner diameter of the first section gradually decreases along the direction of water flow. The second section is close to the downstream end 612 of the water inlet, and the inner diameter of the second section remains unchanged. The grille portion 63 arranged between the water inlet section 61 and the mixing section 62 is located at the position with the smallest inner diameter in the first mixing element 6. Therefore, the grille portion 63 will further reduce the water flow path of the first mixing element 6. The inner diameter of the mixing section 62 gradually increases along the direction of water flow. Therefore, the path of the water flow in the first mixing element 6 is first reduced and then increased. Therefore, the water flow is first accelerated and pressurized when passing through the water inlet section 61, and the flow rate and pressure of the water flow reach the maximum at the position of the grille portion 63. When entering the mixing section 62 with a larger inner diameter, suction will be formed around the radial direction of the water flow, that is, suction will be formed on the gas in the air inlet channel 2 connected to the air inlet 42, thereby promoting the sterilization gas therein to accelerate and flow into the mixing section to merge with the water flow to form sterilization water.

[0054] Among them, the diameter described in the present invention refers to: the cross-sectional area of ​​the position where water (including the water before mixing with the gas and the sterilizing water after mixing with the gas) flows through. When the water flows only in a larger hole, the inner diameter of the hole is the diameter. When the water flow is diverted to multiple small holes, the sum of the inner diameters of the multiple small holes is the diameter. Therefore, the sum of the inner diameters of the multiple water holes 631 of the grille part 63 is the water flow diameter of the grille part 63.

[0055] In addition, the grid portion 63 also has the function of filtering large or slender foreign matter in the water to prevent the gas-water mixing structure 10 from being blocked.

[0056] Continue reading Figures 2 to 4 As shown, the present gas-water dissolving structure 10 further includes a dissolving zone 7, located between the gas-water intersection chamber 4 and the discharge channel 3. Dissolving zone 7 is used to dissolve the sterilizing water therein by slowing its flow rate. Since the sterilizing gas requires a certain amount of time to dissolve in water and must be fully and evenly mixed with the water, the provision of dissolving zone 7 can delay the residence time of the sterilizing water flow therein, thereby providing sufficient time for the water and sterilizing gas to fully dissolve, further enhancing the sterilizing effect of the sterilizing water.

[0057] A second mixing element 8 is provided within the fusion zone 7. This second mixing element 8 has a porous structure to extend the time the sterilizing water remains within the fusion zone 7. The second mixing element 8 blocks the water flow, allowing it to remain within the fusion zone 7 longer and further dissolve the water and sterilizing gas. The porous structure allows the water to flow smoothly through the fusion zone 7 and toward the discharge channel 3. The porous structure of the second mixing element 8 reduces the diameter of the water flow, which, to a certain extent, accelerates and pressurizes the water flow. However, the second mixing element 8 directly blocks the water flow channel, significantly blocking the water flow. Therefore, the combined effect of the two elements ultimately achieves the effect of extending the time the water remains within the fusion zone 7.

[0058] The fusion zone 7 in this example has an arcuate structure, with an upstream fusion side 71 and a downstream fusion side 72 along the direction of water flow. This arcuate structure of the fusion zone 7 causes the water flow directions of the upstream fusion side 71 and the downstream fusion side 72 to be offset, thereby changing the flow direction of the sterilizing water. More specifically, the cylindrical structure is perpendicular to the water inlet channel 1 and the outlet channel 3. As the sterilizing water flows through the fusion zone 7, it forms a vortex, which further extends the water's residence time in the fusion zone 7 by changing its direction. In this example, the water inlet channel 1 and the outlet channel 3 are arranged on opposite sides of the fusion zone 7 in the radial direction and are perpendicular to each other. Therefore, the water flow directions of the upstream fusion side 71 and the downstream fusion side 72 are offset along the radial direction of the fusion zone 7, more specifically, perpendicularly.

[0059] Continue reading Figures 2 to 4 As shown, the second mixing element 8 includes an annular main body 81. The sidewall of the main body 81 is provided with a plurality of water holes 811, forming a porous structure. The outer side of the main body 81 is also provided with a plurality of blades 82 extending radially thereof. The blades 82 are arranged at intervals along the circumferential direction of the main body 81. Thus, the second mixing element 8 forms an impeller structure. The main body 81 of the second mixing element 8 forms a concentric structure with the fusion zone 7. The outer diameter of the main body 81 is smaller than the inner diameter of the fusion zone 7. Therefore, an annular channel is formed between the second mixing element 8 and the fusion zone 7. Without the blades 82, water would likely flow directly through the annular channel and into the discharge channel 3. The blades 82 prevent this phenomenon. Part of the water flow passes through the water holes 811 of the main body 81, while the remaining part pushes the blades 82 to rotate the second mixing element 8, ensuring that the sterilizing gas and water are fully mixed in the fusion zone 7, thereby allowing the sterilizing gas to fully dissolve in the water.

[0060] Example 2

[0061] See Figure 5 and Figure 6As shown, the structures of the main body 5, the first mixing element 6, the fusion zone 7 and the second mixing element 8 of this example are different from those of Example 1, and are described in detail below.

[0062] The main body 5 of this example is a straight cylindrical structure, the water inlet channel 1 and the outlet channel 3 are coaxial, and therefore the fusion zone 7 is also a straight cylindrical structure.

[0063] The first mixing element 6 of this embodiment has a roughly cylindrical structure. A point of discontinuity in its inner diameter is located within the first mixing element 6. This point serves as the boundary between the section adjacent to the water inlet channel 1, which forms the water inlet section 61, and the section further from the water inlet channel 1, which forms the mixing section 62. The water inlet 42 is formed on the sidewall of the mixing section 62. A grille portion 63 is provided within the first mixing element 6. In this embodiment, the grille portion 63 extends from the upstream end 611 of the water inlet in the direction of water flow, forming a centrally recessed structure. The water holes 631 of the grille portion 63 are strip-shaped structures extending radially from the recessed portion. Multiple water holes 631 are arranged circumferentially around the first mixing element 6. Furthermore, a conical protrusion 632 is provided in the center of the grille portion 63. This protrusion 632 not only reduces the diameter of the downstream end 612 of the water inlet (the recessed portion of the grille portion 63 forms the downstream end of the water inlet section), but also guides the water flow, further increasing the water velocity at the downstream end 612. In the direction of water flow, the grille portion 63 gradually reduces the diameter of the water flow, so the air-water intersection chamber of this embodiment also has a diameter-reducing structure, that is, in this example, the diameter of the water flow is reduced by the concave structure of the grille portion 63 and its water holes 631 and protruding structure 632.

[0064] The fusion zone 7 of this example is a straight cylindrical structure, and the water flows through the fusion zone 7 in a straight flow manner. The second mixing element 8 of this example is a single-layer structure. In order to increase the area of ​​the second mixing element 8, the middle part thereof protrudes along the axial direction. The water holes 811 on the second mixing element 8 are staggered along the axial and radial directions of the second mixing element 8. Specifically, the water holes 811 in the middle of the second mixing element 8 extend along the axial direction of the second mixing element 8, which is conducive to the flow of water therethrough; the water holes 811 on the inclined surface around the middle of the second mixing element 8 extend along the radial direction of the second mixing element 8, and there is a certain angle with the water flow, which can slow down the water flow speed and promote the dissolution of gas and water.

[0065] Example 3

[0066] See Figure 7 and Figure 8As shown, this embodiment differs from Example 1 in that the air inlet channel 2 extends into the water inlet channel 1 and is further provided with a water passage 11 extending through the sidewall of the air inlet channel 2. At least a portion of the water flowing from the water inlet channel 1 passes through the water passage 11 and is discharged into the discharge channel 3. The intersection of the air inlet channel 2 and the water passage 11 forms an air-water intersection chamber 4. The water flow within the water passage 11 creates a suction force on the gas, thereby promoting the gas to enter the air-water intersection chamber 4 through the air inlet channel 2. The water passage 11 includes a first water passage hole 111 and a second water passage hole 112 provided on the sidewall of the air inlet channel. The first water passage hole 111 and the second water passage hole 112 are arranged opposite each other along the radial direction of the air inlet channel 2 and are offset axially along the air inlet channel 2. The water passage 11 creates a water flow within the air inlet channel 2 that intersects the airflow direction, thereby generating a Venturi effect and creating a negative pressure within the air inlet channel 2, promoting the entry of the sterilizing gas into the air-water intersection chamber 4. The positions of the first water hole 111 and the second water hole 112 make the water channel 11 extend in roughly the same direction as the water inlet channel 1, so that the water flow from the water inlet channel 1 can flow into the first water hole 111 and out of the second water hole 112, forming a horizontal water flow in the air inlet channel 2, generating negative pressure suction on the sterilization gas.

[0067] In this example, the water inlet channel 1 and the outlet channel 3 form a right angle, and the air inlet channel 2 and the outlet channel 3 extend in the same direction.

[0068] Example 4

[0069] See Figure 9 and Figure 10 As shown, the difference between this example and Example 3 is that this example has two water inlet channels 1, so it can be connected to two different water sources. For example, one of the water inlet channels 1 is used to connect to a tap water pipe with a certain water pressure, and the other water inlet channel 1 is used to connect to a water tank or a water source with a lower water level. The water from this type of water source cannot be actively fed in by gravity or water pressure, so it is necessary to set a water pump at the water inlet channel 1 and the water source to pump water into the water inlet channel 1. The provision of two water inlet channels 1 increases the use scenarios of the air-water dissolution structure 10, reduces the requirements for the water source, and enables the air-water dissolution structure 10 to be applied to the portable flushing device described in Example 5. In addition, in order to prevent the water in one of the water inlet channels 1 from entering the other water inlet channel 1, a one-way valve is provided in each of the two water inlet channels 1 (the one-way valve is not shown in the figure). The one-way valve is a conventional technology in the field and will not be described here.

[0070] The main body 5 is formed into a vortex-like structure with a central cylindrical shape. Two water inlet channels 1 are arranged on opposite sides of the cylinder in a tangential direction, forming a vortex when water enters. The discharge channel 3 is provided on one end face of the cylinder, and the air inlet channel 2 is provided on the other side. The end face of the side with the air inlet channel 2 is provided with a tapered inward depression, allowing water to flow along this tapered surface until it enters the water passage 11. The tapered surface guides the water flow, increasing its tendency to enter the water passage 11, thereby creating a greater suction force on the sterilizing gas and having a positive effect on increasing the concentration of the sterilizing water.

[0071] Example 5

[0072] See Figure 11 As shown, the present invention also discloses a flushing device 100, which includes the air-water dissolving structure 10 ( Figure 10 The gas-water dissolving structure 10 shown is the structure of Example 1). The flushing device 100 also includes a shell 20, a water inlet pipe 30, a sterilizing gas supply component 40 and a spray gun 50. One end of the water inlet pipe 30 is connected to the water inlet channel 1 of the gas-water dissolving structure 10, and the other end of the water inlet pipe 30 is used to connect to a water source. The sterilizing gas supply component 40 is connected to the gas inlet channel 2 of the gas-water dissolving structure 10, and the spray gun 50 is connected to the exhaust channel 3 of the gas-water dissolving structure 10 for spraying out sterilizing water with a sterilization function, so that the flushing device is formed into a portable structure. The sterilizing gas supply component 40 is used to supply sterilizing gas to the gas-water dissolving structure 10. The type of sterilizing gas is ozone or chlorine as described in Example 1. In this example, ozone is preferably used. The sterilizing gas supply component 40 is an ozone generator. Its supply method is the existing technology and will not be repeated here. Accordingly, according to the different types of gas, the sterilizing gas supply component 40 changes accordingly, and its supply method is also the existing technology.

[0073] in, Figure 11 The water inlet pipe 30 is shown as extending directly outside the housing 20, but is not limited to being connected and extending outside the housing 20. In other embodiments, the water inlet pipe 30 can be divided into two sections, namely a first water inlet pipe and a second water inlet pipe. The first water inlet pipe is disposed within the housing with the interface at the end exposed, and the second water inlet pipe is detachably connected to the interface of the first water inlet pipe, so that the second water inlet pipe can be selected as needed. In addition, the second water inlet pipe can be omitted and the interface at the end of the first water inlet pipe can be set as a standard interface, so that it can be directly connected to an external water source with a standard connector.

[0074] The flushing device of this embodiment only needs to be connected to a water source (e.g., a faucet) and then connected to a power source via power plug 401 to power the ozone generator. The spray gun 50 can be used to flush the human body (in this case, the flushing device is formed into a portable bidet or shower), and can also be used to flush a sink or other location that requires flushing. The spray gun 50 of this flushing device is detachable, which allows users to choose whether to install the spray gun 50 according to their needs. It also facilitates the removal and carrying of the spray gun 50, further improving its portability. In other embodiments, the spray gun 50 can also be configured as a non-detachable structure.

[0075] In addition, a handle 21 is provided on the housing 20 of this example to facilitate carrying the portable flushing device 100 of this example.

[0076] Example 6

[0077] See Figure 12 As shown, the difference between this example and Example 5 is that a water pump 60 is further provided between the water inlet pipe 30 and the air-water dissolving structure 10 of this example, so that the flushing device can be connected to a water source that cannot actively supply water, such as a water tank or a water source whose water level is lower than the water inlet channel 1 of the air-water dissolving structure 10. At this time, water is pumped from the water source by the water pump 60, which can not only ensure that there is water supply to the water inlet channel 1, but also ensure that the water pressure entering the air-water dissolving structure 10 is large enough, thereby having sufficient suction force on the gas.

[0078] Example 7

[0079] See Figure 13 As shown, this embodiment is a combination of Embodiment 5 and Embodiment 6, that is, the flushing device is provided with two water inlet pipes 30, one of which is used to connect to a water source with positive pressure water, such as a faucet, and the other is connected to a water source that cannot actively supply water. Water is pumped by a water pump 60 to achieve water inlet channel 1. The air-water dissolution structure 10 provided in the flushing device of this embodiment is the structure shown in Embodiment 4, that is, a structure with two water inlet channels 1. The user can select one of the water inlet pipes 30 to achieve water inlet as needed.

[0080] Example 8

[0081] See Figure 14 As shown, this example discloses a flushing device 100 having the above-mentioned air-water dissolving structure 10. The difference from Example 5 is that the flushing device 100 of this example is fixedly arranged at the water inlet end of the water-using equipment, and the discharge channel 3 of the air-water dissolving structure 10 is used to be connected to the water-using equipment to supply sterilizing water with a sterilization function to the water-using equipment, and the water-using equipment includes but is not limited to at least one of a toilet, a handheld spray gun, a shower and a faucet.

[0082] The following are examples of the use of the flushing device 100:
