In addition, those skilled in the art can combine and combine the different embodiments or examples described in the present application and the features of the different embodiments or examples without contradiction.

[0038] The present application provides a bubble generating structure 1, please refer to Figures 1 to 4The bubble generating structure 1 comprises a shell assembly 10, a bubbling structure 20 and a one-way valve assembly 30.

[0039] Please refer to Figure 2 and Figure 3 The shell assembly 10 has a water inlet 10a, a water outlet 10b and a flow channel 10c for fluid flow, and the flow channel 10c is communicated with the water inlet 10a and the water outlet 10b. The fluid enters the flow channel 10c from the water inlet 10a, and then flows out from the water outlet 10b.

[0040] The bubbling structure 20 is arranged in the flow channel 10c. The bubbling structure 20 is used to generate more micro-bubbles in the fluid flowing through the flow channel 10c.

[0041] It should be noted that the specific structure of the bubbling structure 20 is not limited, as long as it can generate micro-bubbles in the fluid.

[0042] The one-way valve assembly 30 is arranged in the flow channel 10c and located upstream or downstream of the bubbling structure 20 along the direction of fluid flow. That is, the fluid can flow through the bubbling structure 20 first and then flow through the one-way valve assembly 30; or the fluid can flow through the one-way valve assembly 30 first and then flow through the bubbling structure 20.

[0043] It should be noted that the direction of fluid flow refers to the direction of fluid flow from the water inlet 10a to the water outlet 10b.

[0044] It can be understood that the shell assembly 10 can protect the internal bubbling structure 20 and one-way valve assembly 30, so as to ensure the stable operation of the bubbling structure 20 and one-way valve assembly 30.

[0045] The one-way valve assembly 30 allows the fluid to flow from the water inlet 10a to the water outlet 10b, and blocks the fluid from flowing from the water outlet 10b to the water inlet 10a. That is, the water flow unidirectionally flows from the water inlet 10a to the water outlet 10b, and cannot flow from the water outlet 10b to the water inlet 10a.

[0046] The bubble generating structure 1 provided by the embodiment of the present application can not only ensure that the bubble generating structure 1 has the ability to generate micro-bubbles, but also prevent the water flow downstream of the bubble generating structure 1 from flowing reversely through the bubble generating structure 1. In addition, the bubbling structure 20 and the one-way valve assembly 30 are arranged in the shell assembly 10 to ensure the integrity of the bubble generating structure 1, and facilitate the installation of the bubble generating structure 1. For example, when assembling, one of the external pipelines is connected to the water inlet 10a, and the other external pipeline is connected to the water outlet 10b.

[0047] The application scenario of the bubble generating structure 1 of the embodiment of the present application is not limited, such as washing equipment, faucet, etc.

[0048] The application embodiment takes the bubble generating structure 1 applied to a washing device as an example for description.

[0049] The application embodiment provides a washing device, which comprises a box body (not shown in the figure), a cylinder assembly (not shown in the figure), and the bubble generating structure 1 of any of the application embodiments.

[0050] The type of the washing device is not limited, for example, it can be a washing machine, a fruit and vegetable cleaning machine, a shoe washing machine, etc., which is not limited herein.

[0051] The application embodiment takes a washing machine as an example for description of the washing device.

[0052] The cylinder assembly is used to contain washing objects, which can be clothes, shoes, carpets, etc. The cylinder assembly has an opening, through which a user can put in or take out the washing objects.

[0053] The cylinder assembly is arranged in the box body. It can be understood that the box body, as an appearance part of the washing device, can protect the cylinder assembly inside.

[0054] Exemplarily, in some embodiments, the cylinder assembly comprises an outer barrel and an inner cylinder, the outer barrel is sleeved outside the inner cylinder, the outer barrel is used to contain water for clothes washing, and the inner cylinder is used to contain clothes. In this embodiment, the inner cylinder contains water through the outer barrel, and the inner cylinder can also be called a perforated inner cylinder. In other embodiments, the inner cylinder contains water by itself, and can also be called a non-perforated inner cylinder.

[0055] It can be understood that in some embodiments, the cylinder assembly can only have the inner cylinder without the above-mentioned outer barrel. In this embodiment, the inner cylinder is a non-perforated inner cylinder, and the inner cylinder can contain water by itself.

[0056] The bubble generating structure 1 is in communication with the cylinder assembly. It can be understood that the fluid flowing through the bubble generating structure 1 eventually enters the cylinder assembly, so that the fluid flowing into the cylinder assembly has a large number of micro-bubbles, thereby improving the washing effect on the washing objects.

[0057] It should be noted that micro-bubbles generally refer to micro-bubbles with a diameter of less than 50 um (length unit: microns) when the bubbles occur. Micro-bubbles have a small buoyancy in liquid, so they stay in liquid for a long time. Moreover, micro-bubbles shrink in liquid until they finally break, generating smaller nanobubbles. In this process, the bubbles become smaller, so their rising speed becomes slow, resulting in high melting efficiency. In addition, the shrinkage process of micro-bubbles is also accompanied by an increase in negative charge, so micro-bubbles are easy to adsorb positively charged foreign matters floating in liquid, and the micro-bubbles carrying foreign matters slowly float to the surface of the liquid, that is, micro-bubbles have good cleaning and purifying ability.

[0058] In some embodiments, the washing apparatus comprises a water inlet valve and a detergent box. It can be understood that a water source in an external environment can enter the washing apparatus through the water inlet valve.

[0059] The detergent box has a detergent storage cavity for accommodating a detergent. It can be understood that the detergent storage cavity in the detergent box can provide space for the detergent, facilitating the user to supplement the detergent required by the washing apparatus.

[0060] It should be noted that the type of detergent is not limited, which can be a lotion having a stain cleaning effect, or a perfume, a disinfectant, or a laundry care agent for softening, fluffing, and removing static electricity of clothes, etc.

[0061] The bubble generating structure 1 is arranged on the water path between the water inlet valve and the detergent box. It can be understood that after the water source enters the washing apparatus from the water inlet valve, a large number of micro-bubbles are generated by the bubble generating structure 1 to enter the detergent box, which can improve the dissolution efficiency of the detergent.

[0062] It can be understood that the water flowing through the bubble generating structure 1 can be at least divided into two paths, one of which flows through the detergent storage cavity of the detergent box, and the other of which flows to the drum assembly through a closed path. The closed path refers to a path that does not communicate with the external atmosphere, and the water path does not depressurize during the flow in the closed path.

[0063] The one-way valve assembly 30 can block the flow path from the water outlet 10b to the water inlet 10a, and can prevent the washing water in the drum assembly from backflowing.

[0064] In the related art, when the public water path (for example, a tap water path) is shut down, etc., negative pressure is easily generated at the water inlet of the water inlet valve. At this time, if the water level in the drum assembly is high, the washing water in the drum assembly may be sucked into the public water path through the closed path, the bubble generating structure, and the water inlet valve under the siphon effect of the negative pressure of the closed path, which can pollute the public water path.

[0065] The washing apparatus of the embodiments of the present application sets the bubble generating structure 1 on the water path between the water inlet valve and the detergent box. On the one hand, the bubble generating structure 1 blocks the washing water in the drum assembly from flowing to the water inlet valve, reducing the possibility of the public water path being polluted by the washing water. On the other hand, the bubble generating structure 1 generates micro-bubbles, so that the washing apparatus has a better washing effect on the washing object.

[0066] In some embodiments, please refer to Figure 2 and Figure 3The flow channel 10c has a necked section 10c1, and the bubbling structure 20 is arranged on the necked section 10c1. It can be understood that, when the fluid flows through the necked section 10c1, the flow rate of the fluid increases with the decrease of the cross-sectional area of the flow channel 10c, so that the fluid can flow through the bubbling structure 20 at a high flow rate, and the bubbling structure 20 can generate a large number of micro-bubbles.

[0067] It should be noted that the necked section 10c1 refers to the cross-sectional area of the necked section 10c1 decreasing along the direction of fluid flow, i.e. the direction towards the water outlet 10b.

[0068] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 5 The bubbling structure 20 has one or more water-permeable channels 20a. It can be understood that, since the cross-sectional area of the water-permeable channel 20a is smaller than the cross-sectional area of the necked section 10c1, when the fluid at a high flow rate flows from the necked section 10c1 into the water-permeable channel 20a, the fluid is agitated due to the narrowing of the flow channel, causing the dissolved gas in the fluid to be released to form a large number of micro-bubbles.

[0069] The above technical solutions include: first, the bubbling structure 20 includes one water-permeable channel 20a; second, the bubbling structure 20 includes a plurality of water-permeable channels 20a.

[0070] It should be noted that the cross-sectional area of the water-permeable channel 20a is smaller than the cross-sectional area of the necked section 10c1.

[0071] In some embodiments, please refer to Figure 5 The number of water-permeable channels 20a is a plurality, and the plurality of water-permeable channels 20a are distributed in a radial manner. It can be understood that the plurality of water-permeable channels 20a distributed in a radial manner can enhance the degree of agitation of the fluid and improve the speed of generating micro-bubbles of the fluid, so that the fluid flowing through the bubbling structure 20 can generate a large number of micro-bubbles.

[0072] It should be noted that the plurality of water-permeable channels 20a distributed in a radial manner means that the plurality of water-permeable channels 20a are arranged in a radial manner outward from the center of the flow channel 10c in a plane perpendicular to the flow channel 10c.

[0073] Exemplarily, please refer to Figure 5 The specific number of water-permeable channels 20a can be three, and the three water-permeable channels 20a are distributed in a radial manner.

[0074] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 5, the bubble structure 20 and at least a part of the shell assembly 10 are in an integral structure. It can be understood that the connection strength between the shell assembly 10 and the bubble structure 20 can be improved, so as to improve the support strength of the shell assembly 10 to the bubble structure 20, so that the bubble structure 20 can remain stable under the impact of fluid with high flow rate, so as to guarantee that the bubble structure 20 has the ability to stably generate a large number of micro-bubbles in the fluid.

[0075] It should be noted that the bubble structure 20 and at least a part of the shell assembly 10 are in an integral structure, which means that the bubble structure 20 and at least a part of the shell assembly 10 can be produced together, for example, an integrally formed plastic part.

[0076] It should be noted that the specific structure of the one-way valve assembly 30 is not limited.

[0077] In some embodiments, please refer to Figure 2 、 Figure 3 and Figure 4 , the one-way valve assembly 30 includes a valve core assembly 301 and an elastic member 302, the flow channel 10c includes a control section 10c2, the valve core assembly 301 is movably arranged in the flow channel 10c, and the elastic member 302 applies an elastic force to the valve core assembly 301, so that the valve core assembly 301 has a tendency to move in the direction of the water inlet 10a under the action of the elastic force, and then the valve core assembly 301 can be kept in the position of closing the control section 10c2 under the action of the elastic force.

[0078] It can be understood that under the action of the elastic force, the valve core assembly 301 has a tendency to move in the direction of the control section 10c2, so that a part of the valve core assembly 301 is in sealing cooperation with the control section 10c2 to realize the closing of the flow channel 10c by the valve core assembly 301.

[0079] Specifically, when the fluid flows from the water inlet 10a to the water outlet 10b, the fluid applies an action force to the valve core assembly 301 to move in the direction of the water outlet 10b. When the action force of the fluid on the valve core assembly 301 is greater than the elastic force of the elastic member 302 on the valve core assembly 301, the valve core assembly 301 moves in the direction of the water outlet 10b, and the valve core assembly 301 opens the control section 10c2 to allow the fluid to flow from the water inlet 10a to the water outlet 10b. When there is no fluid flowing into the water inlet 10a, or the action force of the fluid on the valve core assembly 301 is less than the elastic force of the elastic member 302 on the valve core assembly 301, the valve core assembly 301 closes the control section 10c2 under the action of the elastic force.

[0080] Conversely, when the fluid flows from the water outlet 10b to the water inlet 10a, the force applied to the valve core assembly 301 by the fluid and the force applied to the valve core assembly 301 by the elastic member 302 are in the same direction, both of which make the valve core assembly 301 have a tendency to move towards the water inlet 10a, so that the valve core assembly 301 still remains in the position of the closed control section 10c2 to block the fluid from flowing from the water outlet 10b to the water inlet 10a.

[0081] It should be noted that the valve core assembly 301 can be in abutting cooperation with the end face of the control section 10c2 close to the water outlet 10b to close the control section 10c2, or a part of the valve core assembly 301 can extend into the control section 10c2 and be in sealing cooperation with the peripheral wall of the control section 10c2 to close the control section 10c2.

[0082] In some embodiments, referring to Figures 2 to 4 , the valve core assembly 301 includes a core head 301a and a guide column 301b, the core head 301a is connected to one end of the guide column 301b, and the elastic member 302 is sleeved on the outer periphery of the guide column 301b, and the valve core assembly 301 opens or closes the flow passage 10c through the core head 301a. It can be understood that when the valve core assembly 301 moves under the action of an external force, the elastic member 302 will be elastically deformed, and the guide column 301b can guide the elastic deformation of the elastic member 302 to prevent the elastic member 302 from laterally tilting and improve the deformation reliability of the elastic member 302.

[0083] In some embodiments, referring to Figure 3 , the cross-sectional area of the control section 10c2 gradually increases along the fluid flow direction, for example, substantially in a trumpet shape, and the core head 301a is used to extend into the control section 10c2 from the outlet side of the control section 10c2 and can be in sealing cooperation with the peripheral wall of the control section 10c2 under the action of the elastic member 302 to achieve closing the flow passage 10c.

[0084] It should be noted that the cross-sectional area of the control section 10c2 gradually increases along the fluid flow direction, which means that the cross-sectional area of the control section 10c2 increases in the direction towards the water outlet 10b, that is, the cross-sectional area of the control section 10c2 decreases in the direction towards the water inlet 10a.

[0085] It should be noted that the outlet side of the control section 10c2 refers to one end of the control section 10c2 in the direction towards the water outlet 10b, that is, one end of the control section 10c2 with a larger cross-sectional area.

[0086] It can be understood that the core head 301a moves towards the water inlet 10a under the elastic force of the elastic member 302. Due to the fact that the cross-sectional area of the control section 10c2 towards the water inlet 10a is reduced, the outer edge of the core head 301a gradually approaches the peripheral wall of the control section 10c2 during the movement, until the core head 301a contacts and sealingly engages with the peripheral wall of the control section 10c2, so as to close the flow channel 10c and block the fluid from flowing from the water outlet 10b to the water inlet 10a through the flow channel 10c.

[0087] In some embodiments, referring to Figures 2 to 4 , the one-way valve assembly 30 comprises a sealing member 303, which surrounds the outer periphery of the core head 301a and is configured to contact the wall of the flow channel 10c. It can be understood that the contact between the sealing member 303 and the wall of the flow channel 10c can effectively block the flow of fluid, so that the valve core assembly 301 can effectively close the flow channel 10c under the elastic force.

[0088] It should be noted that the specific material of the sealing member 303 is not limited, for example, it can be an elastic material. In this way, under the action of the elastic member 302, the sealing member 303 can be in extrusion fit with the wall of the control section 10c2 to close the control section 10c2, which can reduce the damage to the wall of the control section 10c2 caused by the elastic force of the elastic member 302.

[0089] In some embodiments, referring to Figures 2 to 4 , the bubble generating structure 1 comprises a positioning portion 40 arranged in the flow channel 10c, and the positioning portion 40 has a guide hole 40a through which the guide column 301b is slidably arranged.

[0090] It can be understood that, on the one hand, the guide column 301b can slide in the guide hole 40a when the valve core assembly 301 moves under the action of an external force, so that the guide hole 40a can guide the movement of the valve core assembly 301 and prevent the valve core assembly 301 from deviating during the movement; on the other hand, the positioning portion 40 can abut against the elastic member 302 arranged around the outer periphery of the guide column 301b, so that the elastic member 302 can be kept in an elastically deformed state, so that the elastic member 302 can continuously apply an elastic force to the valve core assembly 301 to keep the valve core assembly 301 in a tendency of moving towards the water inlet 10a.

[0091] In some embodiments, referring to Figure 2 , the shell assembly 10 comprises a split cover 101 and a shell 102, the water inlet 10a and the control section 10c2 are arranged on the cover 101, and the water outlet 10b is arranged on the shell 102. The shell 102 has an opening, and the shell 102 and the cover 101 are connected along a first direction, and the cover 101 closes the opening.

[0092] Specifically, the cover 101 comprises the water inlet 10a, the necked section 10c1 and the control section 10c2, the bubble structure 20 is located in the flow channel 10c on one side of the cover 101, and the cover 101 and the shell 102 can be connected together by means of screws, clamping, welding, bonding or the like.

[0093] It is to be noted that the first direction refers to Figure 2 the direction indicated by the arrow in the middle.

[0094] Exemplarily, the one-way valve assembly 30 is arranged in the shell 102 and can move relative to the shell 102 in the first direction to open or close the control section 10c2 on the cover 101. It can be understood that the one-way valve assembly 30 is located in the shell 102, and when the one-way valve assembly 30 moves towards the direction close to the cover 101, i.e. moves towards the direction to close the control section 10c2 on the cover 101, and when the one-way valve assembly 30 moves towards the direction away from the cover 101, i.e. moves towards the direction to open the control section 10c2 on the cover 101.

[0095] In some embodiments, in the orthographic projection in the plane perpendicular to the first direction, the projection of the one-way valve assembly 30 is located in the projection of the opening, so that the one-way valve assembly 30 can be placed into the shell 102 through the opening. In this way, on the one hand, the assembly of the one-way valve assembly 30 and the shell 102 can be facilitated, and the assembly efficiency of the bubble generating structure 1 can be improved; on the other hand, sufficient space is provided between the one-way valve assembly 30 and the shell 102 for fluid flow. When assembling, the valve core assembly 301 and the elastic member 302 are placed into the shell 102 through the opening, and then the cover 101 is assembled on the shell 102.

[0096] In some embodiments, please refer to Figure 2 , the cover 101 comprises the cover part 101c and the water inlet connector pipe part 101d, and the shell 102 comprises the barrel part 102a and the water outlet connector pipe part 102b. It can be understood that the water inlet connector pipe part 101d is used to connect with a pipeline. The water outlet connector pipe part 102b is used to connect with another pipeline.

[0097] Exemplarily, please refer to Figure 3 and Figure 4 , the cover 101 has a connecting part 101a on the outer periphery of the side towards the shell 102, the connecting part 101a extends into the shell 102 and abuts against the wall surface of the shell 102. In this way, the connection sealing property between the cover 101 and the shell 102 can be improved.

[0098] Exemplarily, please refer to Figure 3 and Figure 4The cover 101c closes the opening of the barrel 102a, and the water outlet joint pipe 102b is arranged at the end of the barrel 102a away from the cover 101. The barrel 102a comprises a constricted sub-barrel 102a1 which is constricted inwardly from the cover 101 to the direction of the shell 102, and the constricted sub-barrel 102a1 is connected to the water outlet joint pipe 102b at the end of the extension.

[0099] In this way, the constricted sub-barrel 102a1 can provide sufficient space for installing the valve core assembly 301, so as to make the structure of the bubble generating structure 1 compact, and in addition, the transition of the constricted sub-barrel 102a1 to the water outlet joint pipe 102b is smooth, so that the fluid flows smoothly from the constricted sub-barrel 102a1 to the water outlet joint pipe 102b.

[0100] Exemplarily, the outer peripheral wall of the water inlet joint pipe 101d has a plurality of protrusions 10d. It can be understood that when the water inlet joint pipe 101d is connected to the water channel of the washing equipment, the protrusions 10d can play a role of anti-falling to improve the connection strength of the water inlet joint pipe 101d and the water channel.

[0101] Exemplarily, the outer peripheral wall of the water outlet joint pipe 102b has a plurality of protrusions 10d. It can be understood that when the water outlet joint pipe 102b is connected to the water channel of the washing equipment, the protrusions 10d can play a role of anti-falling to improve the connection strength of the water outlet joint pipe 102b and the water channel.

[0102] In some embodiments, please refer to Figure 3 and Figure 4 The cover 101 has a convex barrel 102a on the side facing the shell 102, the convex barrel 102a extends towards the shell 102 and the cross-sectional area increases, and the space in the convex barrel 101b forms a control section 10c2. It can be understood that there is a gap between the outer edge of the convex barrel 101b and the wall surface of the shell 102, so that the convex barrel 101b does not affect the connection of the cover 101 and the shell 102, and the structure of the shell assembly 10 is compact after the cover 101 and the shell 102 are closed.

[0103] The following describes the movement process of a specific embodiment of the present application in combination with the accompanying Figure 3 and Figure 4 , please refer to Figure 3, the control section 10c2 is in the closed state, the valve core assembly 301 has a tendency to move in the direction of the water inlet 10a under the elastic force of the elastic member 302, and the sealing member 303 is in contact with the wall surface of the control section 10c2 to close the control section 10c2 and block the fluid from flowing from the water outlet 10b to the water inlet 10a. When the fluid flows from the water inlet 10a to the water outlet 10b, the fluid applies an action force to the valve core assembly 301 to move in the direction of the water outlet 10b, so that the valve core assembly 301 moves in the direction of the water outlet 10b against the elastic force, and at the same time, the elastic member 302 is compressed to store elastic potential energy, and the sealing member 303 is separated from the wall surface of the control section 10c2, so that the control section 10c2 is switched from the closed state shown in Figure 3 to the open state shown in Figure 4 to allow the fluid to flow from the water inlet 10a to the water outlet 10b. In the open state shown in Figure 4 , when the external force is removed, the valve core assembly 301 moves in the direction of the water inlet 10a under the action of the elastic potential energy of the elastic member 302, and the sealing member 303 is in contact with the wall surface of the control section 10c2, so that the control section 10c2 is switched from the open state shown in Figure 4 to the closed state shown in Figure 3 .
