[0044] Next, refer to Figures 1-9 Describe the aeration device 10 according to an embodiment of the present invention.

[0045] As Figure 6 、 Figure 8As shown, the aeration device 10 according to the present invention includes: a housing 11 and a flow divider 12. An accommodation chamber 110a is formed inside the housing 11, at least a part of the outer surface of the housing 11 is configured as a flow dividing surface 112, and a flow dividing hole 113 communicating with the accommodation chamber 110a is formed on the flow dividing surface 112; the flow divider 12 is disposed on the flow dividing surface 112 and forms a flow dividing channel, and the flow dividing channel communicates with the flow dividing hole 113. Specifically, when the aeration device 10 is in a target gas or a target liquid, the aeration device 10 is adapted to disperse the air flow in the accommodation chamber 110a into multiple strands and diffuse it into the target gas or the target liquid, so that the air flow is fully mixed with the target gas or the target liquid. Among them, the accommodation chamber 110a inside the housing 11 can accommodate the air flow. Since the flow dividing hole 113 is formed on the flow dividing surface 112 of the housing 11, the air flow in the accommodation chamber 110a is dispersed into multiple strands by the flow dividing hole 113 after flowing through the flow dividing surface 112. The flow divider 12 located on the flow dividing surface 112 forms a flow dividing channel, and the air flow flowing through the flow dividing hole 113 and dispersed into multiple strands diffuses into the target gas or the target liquid around the aeration device 10 under the action of the flow dividing channel.

[0046] The aeration device 10 according to the present invention disperses the air flow into multiple strands by providing the flow dividing hole 113 and the flow divider 12 and makes the air flow diffuse towards the target gas or the target liquid. The aeration device 10 can be applied to gas-gas mixing or gas-liquid mixing. By dispersing the air flow into multiple strands and diffusing it through the aeration device 10, the contact area and contact time between the air flow and the target gas or the target liquid are increased, so that the air flow is fully in contact with the target gas or the target liquid, and then the air flow is fully mixed with the target gas or the dissolved amount of the air flow in the target liquid is increased, thereby enhancing the effect of gas-gas mixing or gas-liquid mixing.

[0047] According to some embodiments of the present invention, as Figures 6-9 shown, the flow divider 12 forms a plurality of flow dividing channels, and the plurality of flow dividing channels are arranged at intervals. Specifically, the flow dividing channels are adapted to guide the flow directions of the air flow dispersed into multiple strands by the flow dividing hole 113. There are a plurality of flow dividing channels, and the plurality of flow dividing channels can be arranged in different directions to diffuse the multiple strands of air flow in different directions, so that the multiple strands of air flow diffuse into the target gas or the target liquid around the aeration device 10 from different directions. More specifically, the flow dividing channels extend in the radial direction of the flow divider 12 to guide the air flow to diffuse towards the target gas or the target liquid. In some embodiments, the plurality of flow dividing channels are arranged at intervals in the circumferential direction of the flow divider 12 to diffuse the air flow in the circumferential direction of the flow divider 12 into the target gas or the target liquid, so that the air flow is more fully in contact with the target gas or the target liquid, so that the air flow is fully mixed with the target gas or the dissolved amount of the air flow in the target liquid is increased, and the mixing effect between the air flow and the target gas or the target liquid is enhanced.

[0048] According to some embodiments of the present invention, as Figures 6-9As shown, the flow splitter 12 includes a base portion 122 and vanes 123. The base portion 122 is fixedly connected to the flow splitting surface 112; one end of each vane 123 is connected to the base portion 122 and the other end extends radially away from the base portion 122. The vanes 123 are configured to be multiple and arranged at intervals in the circumferential direction of the base portion 122, and a flow splitting channel is formed between two adjacent vanes 123. Specifically, the base portion 122 of the flow splitter 12 is adapted to be connected to the flow splitting surface 112 to fix the flow splitter 12 to the housing 11. The vanes 123 are configured to be multiple and the multiple vanes 123 are arranged at intervals in the circumferential direction of the base portion 122. A flow splitting channel is formed between two adjacent vanes 123. The flow splitting channels extend radially of the base portion 122 and the multiple flow splitting channels are arranged at intervals in the circumferential direction of the base portion 122. More specifically, one end of each vane 123 is connected to the base portion 122, and the other end of the vane 123 extends in the radial direction of the base portion 122 away from the base portion 122 to define a flow splitting channel with a relatively large radial coverage area of the base portion 122, so that the flow splitting channel can diffuse the airflow in a direction away from the base portion 122, thereby increasing the diffusion range of the flow splitter 12 for the airflow.

[0049] According to some embodiments of the present invention, as Figures 8-9 shown, each vane 123 is inclined in a clockwise or counterclockwise direction in a direction away from the flow splitting surface 112. Specifically, the multiple vanes 123 are arranged at intervals in the radial direction of the base portion 122 and are inclined in a direction away from the flow splitting surface 112 to form multiple flow splitting channels that can radially diffuse the airflow around the flow splitter 12. The airflow in the accommodation cavity 110a is dispersed into multiple strands by the flow splitting holes 113 and uniformly radially diffuses around by the multiple flow splitting channels of the base portion 122, enhancing the disturbance effect of the airflow on the target gas or target liquid.

[0050] According to some embodiments of the present invention, as Figures 6-7 shown, the flow splitter 12 further includes a flow splitting cover 124. The flow splitting cover 124 is configured to be annular or arc-shaped and is connected to the multiple vanes 123. The diameter of the flow splitting cover 124 gradually increases in a direction away from the flow splitting surface 112. Specifically, the flow splitting cover 124 is configured to be annular or arc-shaped to form a flow splitting channel that can diffuse the airflow around the flow splitter 12. The airflow in the accommodation cavity 110a is dispersed into multiple strands by the flow splitting holes 113 and uniformly radially diffuses around by the flow splitting channels in the circumferential direction of the base portion 122, enhancing the disturbance effect of the airflow on the target gas or target liquid.

[0051] According to some embodiments of the present invention, as Figures 6-7As shown, the flow splitters 124 are configured as multiple ones centered on the axis of the base portion 122, and the multiple flow splitters 124 are arranged at intervals in the radial direction. Specifically, the flow splitters 124 are configured as multiple concentric ones. The flow splitter 124 with the smallest diameter is fixed to the base portion 122 and connected to the blades 123. The multiple blades 123 sequentially connect the multiple flow splitters 124 with different diameters so that the multiple flow splitters 124 are arranged at intervals in the radial direction. A flow splitting channel is formed between two adjacent flow splitters 124, and the multiple flow splitting channels diffuse the airflow layer by layer towards the surroundings.

[0052] In some embodiments, as Figure 9 shown, the multiple blades 123 of the flow splitter 12 are arranged at intervals in the radial direction of the base portion 122 and are inclined in the direction away from the flow splitting surface 112. The flow splitter 12 can radiate and diffuse multiple airflows towards the surroundings; in other embodiments, as Figure 7 shown, the flow splitters 124 of the flow splitter 12 are configured as multiple concentric ones. A flow splitting channel is formed between two adjacent flow splitters 124. The flow splitter 12 can diffuse multiple airflows layer by layer towards the surroundings; in other embodiments, the multiple blades 123 of the flow splitter 12 are arranged at intervals in the horizontal direction (there is no attached drawing for this embodiment), and the included angle between two adjacent blades 123 is α and the multiple blades 123 are not parallel. The flow splitter 12 can radiate and diffuse multiple airflows towards the surroundings. It can be understood that the blades 123 of the flow splitter 12 can also be set into other shapes with the effect of dispersing the airflow.

[0053] According to some embodiments of the present invention, as Figure 4 shown, a convex portion 114 protruding towards the outside is formed on the flow splitting surface 112. As Figure 6 , Figure 8 shown, a concave portion cooperating with the convex portion 114 is formed on one side of the base portion 122 facing the convex portion 114. A first mounting hole 115 is provided on the end surface of the convex portion 114, and a second mounting hole 126 penetrating in the thickness direction and corresponding to the first mounting hole 115 is provided on the base portion 122. Specifically, the base portion 122 of the flow splitter 12 is adapted to be connected to the flow splitting surface 112 to fix the flow splitter 12 to the housing 11. Among them, the flow splitting surface 112 is formed with the convex portion 114, the convex portion 114 is formed with the first mounting hole 115, and the base portion 122 is formed with the concave portion, and the concave portion is formed with the second mounting hole 126. The convex portion 114 and the concave portion cooperate to make the first mounting hole 115 and the second mounting hole 126 concentric. By sequentially passing a fixing member through the second mounting hole 126 and the first mounting hole 115, the flow splitter 12 can be fixed to the flow splitting surface 112, which can ensure the stability of the structure of the aeration device 10 during operation.

[0054] According to some embodiments of the present invention, as Figure 4As shown, the diversion holes 113 are configured as multiple groups arranged circumferentially on the diversion surface 112, and each group of diversion holes 113 has a plurality of diversion holes 113 arranged at intervals in the radial direction. Specifically, there are multiple groups of diversion holes 113 and they are arranged circumferentially on the diversion surface 112. Each group of diversion holes 113 includes a plurality of diversion holes 113, and the plurality of diversion holes 113 are arranged at intervals in the radial direction of the diversion surface 112. The plurality of diversion holes 113 are evenly arranged on the diversion surface 112 to disperse the air flow flowing out of the diversion holes 113 into multiple strands, and the multiple strands of air flow are fully contacted with the target gas or target liquid under the diffusion of the diverting member 12, thereby enhancing the mixing degree of the air flow with the target gas or target liquid.

[0055] According to some embodiments of the present invention, as Figure 4 shown, the housing 11 includes a box body 110 and a cover body 118. As Figure 5 shown, the box body 110 forms a receiving cavity 110a that is open to the outside; the cover body 118 is detachably engaged with the box body 110 and closes the open end of the receiving cavity 110a; wherein, a diversion surface 112 is formed on the box body 110 and / or the cover body 118.

Specifically, the box body 110 is provided with an air inlet 117 and a flow splitting hole 113 that are respectively communicated with the accommodating cavity 110a. Airflow enters the accommodating cavity 110a from the air inlet 117 and flows out of the accommodating cavity 110a from the flow splitting hole 113. The limiting rib 111 is formed on the side of the flow splitting surface 112 facing the accommodating cavity 110a. The limiting rib 111 defines a flow splitting hole arrangement area on the flow splitting surface 112, and the limiting rib 111 communicates the air inlet 117 with the flow splitting hole 113. A groove adapted to cooperate with the limiting rib 111 is formed on the cover body 118. When the cover body 118 is cooperated with the box body 110, the limiting rib 111 is snapped into the groove on the cover body 118, thereby enhancing the stability degree after the cooperation between the cover body 118 and the box body 110.

[0058] In some embodiments of the present invention, as Figure 4 , Figure 5 , Figure 8 , Figure 9 shown, the aeration device 10 includes a housing 11 and a flow splitting member 12.

[0060] The laundry treatment device 1 according to the present invention will be briefly described below.

[0061] As Figures 1-3 shown, the laundry treatment device 1 according to the present invention includes: a laundry treatment tub 20 and an aeration device 10. A laundry treatment chamber 21 is formed inside the laundry treatment tub 20; the aeration device 10 is arranged inside the laundry treatment chamber 21, and the aeration device 10 is configured as the aeration device 10 described in any one of the above embodiments. Specifically, a laundry treatment chamber 21 is formed inside the laundry treatment tub 20. When the laundry treatment device 1 performs laundry treatment work, washing water can be introduced into the laundry treatment chamber 21. Since the density of the washing water is greater than the density of the air flow inside the aeration device 10, the aeration device 10 is arranged at the bottom of the laundry treatment tub 20. The aeration device 10 disperses the air flow into multiple strands. When the multiple strands of air flow contact the washing water, the multiple strands of air flow become multiple small bubbles. Under the action of the diversion member 12, the multiple bubbles uniformly diffuse into the washing water, and the multiple bubbles rise in the washing water and dissolve therein. The diversion holes 113 disperse the air flow into small bubbles, and the diversion member 12 expands the diffusion area of the bubbles in the washing water, enhancing the disturbance effect of the bubbles on the washing water, enabling the bubbles to fully contact the washing water, and increasing the dissolution amount of the air flow in the washing water. Since the laundry treatment device 1 according to the present invention is provided with the aeration device 10 of the above embodiment, the laundry treatment device 1 can disperse the air flow into multiple strands and change the air flow direction, so that the air flow can fully contact and mix with the washing water, thereby increasing the dissolution amount of the air flow in the washing water.

[0062] In some embodiments, the diversion surface 112 of the aeration device 10 located at the bottom of the laundry treatment tub 20 can face the bottom of the laundry treatment chamber 21 or other directions.

The ozone generator 30 is communicated with the accommodation chamber 110a. Specifically, the ozone generator 30 is communicated with the air inlet 117 of the aeration device 10. The ozone generated by the ozone generator 30 can enter the accommodation chamber 110a through the air inlet 117. The aeration device 10 can disperse the ozone into multiple small bubbles and uniformly diffuse the multiple small bubbles into the washing water, enabling the ozone to fully contact the washing water, increasing the dissolution amount of the ozone in the washing water, and thus enabling the laundry treatment device 1 to have a better sterilization effect on the laundry.

[0064] In some embodiments, as Figures 1-2As shown, the aeration device 10 further includes an air pump 40. The air pump 40 is connected to the ozone generator 30 and is adapted to pump ozone from the air inlet 117 to the accommodation chamber 110a. Under the action of the air pump 40, the ozone entering the accommodation chamber 110a has a certain speed so that the ozone can pass through the diversion holes 113 and the diversion member 12 and enter the washing water. When the washing water reaches a certain water level, the gas generated by the air pump 40 brings the ozone generated by the ozone generator 30 into the aeration device 10. The ozone airflow first flows out from the diversion holes 113. Since the diversion holes 113 are small in size and numerous in quantity, the ozone airflow forms multiple fine bubbles. The ozone bubbles diffuse to the surroundings under the action of the diversion member 12 and are evenly dispersed in the washing water. The bubbles rise in the washing water and dissolve therein to form ozone water, so as to disinfect and sterilize the clothes in the clothes treatment chamber 21.

[0065] In some embodiments, as Figure 2 shown, the aeration device 10 is arranged in the clothes treatment chamber 21. The clothes treatment chamber 21 contains washing water, and the aeration device 10 is placed in a liquid environment. After removing the cover 118, solid particles can be put into the accommodation chamber 110a. The ozone entering the accommodation chamber 110a from the air inlet 117 first contacts the solid particles and flows to the diversion surface 112 through the gaps between the multiple solid particles. The multiple solid particles can preliminarily break up the ozone. The broken-up ozone is dispersed into multiple strands under the action of the diversion holes 113 on the diversion surface 112. The multiple strands of airflow diffuse to the surroundings under the action of the diversion member 12. Adding solid particles into the accommodation chamber 110a can enhance the ozone dispersion ability of the aeration device 10 and accelerate the speed of the aeration device 10 to disperse ozone, so that the aeration device 10 can blow out more and finer ozone bubbles into the washing water within a certain time, thereby enabling the ozone to fully contact the washing water, increasing the dissolution amount of ozone in the water, and thus improving the sterilization effect on the clothes when the clothes treatment device 1 performs clothes treatment work, and enhancing the user experience.

[0066] In summary, the aeration device 10 of the present invention is provided with diversion holes 113 and a diversion member 12. The diversion holes 113 can disperse ozone into small bubbles, and the diversion member 12 can expand the diffusion range of the ozone bubbles in the washing water. By dispersing the ozone into multiple strands and diffusing it through the aeration device 10, the disturbance effect of the ozone bubbles on the washing water can be enhanced, thereby increasing the contact area and contact time between the ozone and the washing water, enabling the ozone to fully contact the washing water, increasing the dissolution amount of ozone in the washing water, and being beneficial to improving the sterilization effect when the clothes treatment device 1 performs ozone sterilization on clothes.
