[0007] According to one embodiment of the present invention, the bubble cutting assembly is recessed in a direction away from the gas-liquid mixing assembly along the water flow direction, thereby forming a recessed structure.

[0008] According to one embodiment of the present invention, the impurity discharge passage is installed along the water flow direction at the position of the maximum depth of the recessed structure.

[0009] According to one embodiment of the present invention, the bubble cutting assembly protrudes in a direction approaching the gas-liquid mixing assembly along the water flow direction, thereby forming a protruding structure.

[0012] According to one embodiment of the present application, the recessed structure is installed coaxially with respect to the gas-liquid mixing assembly, and the protruding structure is installed annularly around the recessed structure, or The protruding structure is installed coaxially with respect to the gas-liquid mixing assembly, and the recessed structure is installed in an annular manner around the protruding structure.

[0013] According to one embodiment of the present application, the impurity discharge passage is located in the center of the recessed structure and / or The impurity discharge passage is provided at the position where the protruding structure is furthest from its center.

[0014] According to one embodiment of the present application, the number of the protruding structures is multiple, and the recessed structure is located between two adjacent protruding structures, and / or The number of recessed structures is multiple, and the protruding structure is located between two adjacent recessed structures.

By installing the gas-liquid mixing assembly, air is introduced into the gas-liquid mixing assembly and mixed with the water stream to generate bubbles, forming bubble water. By installing the bubble cutting assembly, the bubble cutting assembly can cut the bubbles in the bubble water into fine bubbles. When microbubble water is formed, the microbubble water removes the dirt on capillaries and fresh fruits and vegetables, enhancing the cleanliness.

[0025] Also, at least a part of the bubble cutting assembly forms an angle with the first direction and the angle is not equal to 90 degrees, so the bubble cutting assembly is not installed horizontally but is installed inclined. When impurities remain in the bubble cutting assembly, the bubble cutting assembly serves as a guide inclined surface. When a high-speed jet water stream is sprayed, the impurities slide down along the bubble cutting assembly to the bottom of the bubble cutting assembly along the water flow direction. That is, the impurities gather at the bottom of the bubble cutting assembly and do not spread throughout the bubble cutting assembly, reducing the risk of clogging of the entire bubble cutting assembly. Further, in order to prevent the impurities of the microbubble generator from remaining in the bubble cutting assembly, an impurity discharge passage for discharging impurities is installed in the bubble cutting assembly, so that the impurities are discharged from the inside of the microbubble generator.

[0030] Furthermore, it will be understood that, in this description, directional terms such as “up,” “down,” “inside,” and “outside” as described in the embodiments of this disclosure are described from the viewpoint shown in the accompanying drawings and should not be interpreted as limitations to the embodiments of this disclosure. Also, when, in context, one element or feature is referred to as being connected to the “up,” “down,” “inside,” or “outside” of another element(s), it is possible not only to be directly connected to the “up,” “down,” or “inside” of another element(s), but also indirectly connected to the “up,” “down,” or “inside,” or “outside” of other (one or more) elements via an intermediate element.

[0031] One embodiment of the present invention provides a microbubble generator, referring to Figures 1 to 3, which comprises a filtration component 1, a gas-liquid mixing assembly 2, and a bubble-cutting assembly 3. The filtration component 1 is used to filter the water flow, the gas-liquid mixing assembly 2 is used to form the water flow into bubble water, the discharge direction of the gas-liquid mixing assembly 2 is set to a first direction, and the bubble-cutting assembly 3 is used to cut the bubbles in the bubble water into fine bubbles in order to form microbubble water.

[0032] The microbubble generator provided in this embodiment achieves primary filtration against the water flow in the direction of the water flow by installing a filtration component 1, thereby preventing impurities from entering the microbubble generator. By installing a gas-liquid mixing assembly 2, air is introduced into the gas-liquid mixing assembly 2 and mixed with the water flow to generate bubbles and form bubble water. By installing a bubble-cutting assembly 3, the bubble-cutting assembly 3 can cut the bubbles in the bubble water into fine bubbles, forming microbubble water. This microbubble water removes dirt from capillaries and fruits and vegetables, improving cleanliness.

[0033] To avoid affecting the lifespan of the bubble cutting assembly 3 by preventing impurities from remaining in the bubble cutting assembly 3 and causing clogging when the bubble cutting assembly 3 cuts the bubble water, at least a portion of the bubble cutting assembly 3 provided in this embodiment, as shown in Figures 2-3, forms a first direction and angle, and the bubble cutting assembly 3 is provided with an impurity discharge passage 31 for discharging impurities in the microbubble water along the water flow direction. Of these, the angle is less than 90 degrees or greater than 90 degrees.

[0034] In this embodiment, the microbubble generator is installed at an angle rather than horizontally, such that at least a portion of the bubble cutting assembly 3 forms a first direction and angle, and the angle is set to be less than 90 degrees or greater than 90 degrees. If impurities remain in the bubble cutting assembly 3, the bubble cutting assembly 3 acts as a guide inclined surface, and when a high-speed jet of water is injected, the impurities slide down along the bubble cutting assembly 3 to the bottom of the bubble cutting assembly 3 along the direction of the water flow. In other words, the impurities accumulate at the bottom of the bubble cutting assembly 3 and do not spread throughout the entire bubble cutting assembly 3, reducing the risk of clogging of the entire bubble cutting assembly 3. Furthermore, to prevent impurities from remaining in the bubble cutting assembly 3 of the microbubble generator, the bubble cutting assembly 3 is provided with an impurity discharge passage 31 for discharging impurities from inside the microbubble bubbler.

[0035] The impurity discharge passage 31 is positioned in the same direction as the water flow, and the water jet provides power to the movement of the impurities. This arrangement facilitates the smooth discharge of impurities from the impurity discharge passage 31, resulting in an excellent impurity removal effect.

[0036] Furthermore, if the water flow direction is vertical, the discharge direction of the gas-liquid mixing assembly 2 may also be vertical, or it may have a certain angle with respect to the vertical. When the discharge direction of the gas-liquid mixing assembly 2 is vertical, the first direction shown in the direction of arrow X in Figure 2 is the water flow direction, and the second direction shown in the direction of arrow Y in Figure 2 is the horizontal direction. In this case, it can be understood that the first and second directions are installed perpendicular to each other. Of these, if the filtration component 1, gas-liquid mixing assembly 2, and bubble cutting assembly 3 are installed along the water flow direction, the gas-liquid mixing assembly 2 and the bubble cutting assembly 3 are installed in order from top to bottom.

[0037] In one embodiment, as shown in Figures 2 to 4, the filtration component 1 comprises a support member and a filtration member, the support member being an annular filter screen, and the support member being used to mount and support the filtration member. At least a portion of the filtration member is installed at an inclination with respect to a second direction.

[0038] In this invention, since the filtration component is installed at an angle, if a large amount of impurities remain in the bubble cutting assembly 3, the bubble cutting assembly 3 acts as a guide inclined surface. When a high-speed jet of water is injected, the impurities slide down along the bubble cutting assembly 3 to the bottom of the bubble cutting assembly 3 in the direction of the water flow. That is, the impurities gather at the bottom of the bubble cutting assembly 3 and do not spread throughout the entire bubble cutting assembly 3, reducing the risk of clogging of the entire bubble cutting assembly 3. The filtration component is installed horizontally, and impurities that accumulate in the filtration component can also be washed away by removing the microbubble generator. The microbubble generator does not necessarily need to have a filtration component installed.

[0039] In one embodiment, as shown in Figures 2, 3, and 5, the microbubble generator further comprises a water outlet cover 4, the filtration component 1 is installed upstream of the gas-liquid mixing assembly 2 along the water flow direction, and the bubble cutting assembly 3 is installed between the water outlet cover 4 and the gas-liquid mixing assembly 2.

[0040] By installing the filtration component 1 upstream of the gas-liquid mixing assembly 2 along the direction of water flow, primary filtration along the direction of water flow is achieved, preventing large impurities from entering the microbubble generator. For the discharge of fine bubbles, the bubble cutting assembly 3 is installed between the discharge surface cover 4 and the gas-liquid mixing assembly 2, that is, the discharge surface cover 4 is installed downstream of the bubble cutting assembly 3 along the direction of water flow.

[0041] Furthermore, the water outlet cover 4 is equipped with a water outlet, which is connected to the impurity discharge passage 31. As a result, impurities that flow out from the impurity discharge passage 31 are discharged through the water outlet, creating a discharge space for the final removal of impurities. This prevents clogging of the impurity discharge passage 31 and ensures cleanliness inside the microbubble generator.

[0042] In one embodiment, as shown in Figures 2 and 3, the gas-liquid mixing assembly 2 comprises a flow divider 21 and a mixer 22. The discharge surface cover 4 covers the mixer 22 and the flow divider 21, thereby forming an air supply passage between the side wall of the mixer 22 and the side wall of the flow divider 21, and the air supply passage communicates with the first chamber 100. A second chamber 200 is formed between the discharge surface cover 4 and the mixer 22, and the bubble cutting assembly 3 is installed inside the second chamber 200. An air supply passage may also be formed between the side wall of the discharge surface cover 4 and the side wall of the flow divider 21.

[0043] As the water flow passes sequentially through the first water inlet 211 and the second water inlet 221, the flow area of ​​the second water inlet 221 is larger than that of the first water inlet 211. Based on Bernoulli's principle, a certain negative pressure is generated inside the second water inlet 221, causing outside air to pass sequentially through the air supply channel and the first chamber 100 before being drawn into the second water inlet 221. This creates a mixed water flow containing water and some bubbles, which then enters the second chamber 200.

[0044] In one embodiment, as shown in Figure 6, the impurity discharge passage 31 is installed along the water flow direction at a position where the bubble cutting assembly 3 is furthest from the gas-liquid mixing assembly 2.

[0045] By positioning the impurity discharge passage 31 at the location where the bubble cutting assembly 3 is furthest from the gas-liquid mixing assembly 2, that is, by positioning the impurity discharge passage 31 at the bottom of the bubble cutting assembly 3 along the direction of water flow, impurities slide down along the bubble cutting assembly 3 to the bottom of the bubble cutting assembly 3 along the direction of water flow. This allows the impurity discharge passage 31 to properly align with the sliding impurities, meaning that the impurities and the impurity discharge passage 31 are positioned opposite each other, ensuring that the impurities completely enter the impurity discharge passage 31. This facilitates the washing of impurities into the impurity discharge passage 31 during flushing with high-speed jet injection, thereby achieving the impurity discharge process.

[0046] In one embodiment, as shown in Figure 6, the bubble cutting assembly 3 is recessed in the direction away from the gas-liquid mixing assembly 2 along the water flow direction, forming a recessed structure 32.

[0047] The bubble cutting assembly 3 is recessed away from the gas-liquid mixing assembly 2. Exemplarily, the recessed structure 32 is formed in a flared shape with a large end positioned toward the gas-liquid mixing assembly 2 and a small end positioned toward the discharge surface cover 4. In this case, the two side walls of the recessed structure 32 are set at an angle with respect to the second direction, allowing impurities to slide along the inclined groove walls, and the recessed structure 32 serves to accumulate impurities. It is understandable that the impurities do not spread to the side walls but accumulate at the bottom of the groove of the recessed structure 32 along the groove walls, thus avoiding widespread clogging of the groove walls of the recessed structure 32.

[0048] In one embodiment, the impurity discharge passage 31 is installed at the maximum depth of the recessed structure 32 along the direction of water flow.

[0049] By positioning the impurity discharge passage 31 at the maximum depth of the recessed structure 32, that is, by positioning the impurity discharge passage 31 at the bottom of the groove of the recessed structure 32, many impurities accumulate at the bottom of the groove of the recessed structure 32 along the groove wall of the recessed structure 32. As a result, the impurity discharge passage 31 is appropriately positioned opposite the point where impurities accumulate in the bubble-cutting assembly 3, ensuring that impurities are discharged directly from the impurity discharge passage 31.

[0050] If the recessed structure 32 is symmetrical with respect to the axis of the microbubble assembly, then it can be understood that the impurity discharge passage 31 is located at the center of the recessed structure 32 along the second direction, and the impurity discharge passage 31 is located near the accumulation point.

[0051] In some embodiments, the recessed structure 32 may be asymmetrical with respect to the axis of the microbubble assembly. In this case, the impurity discharge passage 31 should be placed at the lowest position of the recessed structure 32 along the water flow direction.

[0052] In one embodiment, as shown in Figures 6 to 8, the impurity discharge passage 31 is a through-hole provided in the bubble cutting assembly 3. By simply opening a through-hole directly into the bubble cutting assembly 3, the impurity discharge passage 31 can be formed, resulting in a simple structure, easy implementation, and low manufacturing costs.

[0053] Specifically, the cross-sectional shape of the through-hole is one of a circle, arc, triangle, or polygon. In this embodiment, the specific shape of the through-hole, i.e., the impurity discharge passage 31, is not limited and can be adjusted according to the actual requirements in manufacturing.

[0054] It can be understood that the impurity discharge passage 31 installed in the recessed structure 32 may be a circular hole structure so that impurities along the circumferential direction of the bubble-cutting assembly 3 uniformly gather towards the center.

[0055] Furthermore, the recessed structure 32 and the water outlet cover 4 can be enclosed by a conical structure, where the cross-section of the conical structure is triangular. In this case, the maximum depth of the recessed structure 32 along the water flow direction is the position where the recessed structure 32 and the water outlet cover 4 come into contact. The recessed structure 32 and the water outlet cover 4 can also be enclosed by a frustoconical structure. In this case, the minimum height of the recessed structure 32 along the water flow direction is the bottom surface of the frustoconical structure along the water flow direction. In this case, the bottom surface can provide a force to support the bubble cutting assembly 3 with the water outlet cover 4, and can also provide a large installation space for the impurity discharge passage 31.

[0056] In one embodiment, as shown in Figure 9, the bubble cutting assembly 3 protrudes in a direction approaching the gas-liquid mixing assembly 2 along the water flow direction, forming a protruding structure 33.

[0057] The bubble cutting assembly 3 protrudes toward the gas-liquid mixing assembly 2, and exemplary, the protruding structure 33 is formed in a flared structure with a large end positioned toward the discharge surface cover 4 and a small end positioned toward the gas-liquid mixing assembly 2. In this case, the two side walls of the protruding structure 33 are inclined with respect to the second direction, allowing impurities to slide along the inclined side walls, and the protruding structure 33 performs the function of dispersing impurities. It can be understood that the impurities do not spread across the entire side wall but are dispersed along the side wall down to the bottom of the protruding structure 33, thus avoiding widespread clogging of the side wall of the protruding structure 33.

[0058] In one embodiment, as shown in Figures 9 to 11, the impurity discharge passage 31 is located at the minimum height of the protruding structure 33 along the water flow direction.

[0059] Since many impurities are dispersed along the side walls of the protruding structure 33 up to the edge of the protruding structure 33, by installing the impurity discharge passage 31 at the minimum height of the protruding structure 33, that is, by installing the impurity discharge passage 31 at the edge of the protruding structure 33, the impurity discharge passage 31 will be appropriately positioned opposite the impurity dispersion points in the bubble cutting assembly 3, ensuring that the impurities are discharged directly from the impurity discharge passage 31.

[0060] If the protruding structure 33 is symmetrical with respect to the axis of the microbubble assembly, then it can be understood that the impurity discharge passage 31 is located along the second direction at the position furthest from the center of the protruding structure 33, and that the impurity discharge passage 31 is located near the dispersion point.

[0061] In some embodiments, the protruding structure 33 may be asymmetrical with respect to the axis of the microbubble assembly. In this case, it is understandable that the impurity discharge passage 31 should be placed at the lowest position of the protruding structure 33 along the water flow direction.

[0062] As shown in Figures 9 to 11, it can be understood that the impurity discharge passage 31 installed in the protruding structure 33 may be an arc-shaped hole structure corresponding to a semicircular hole structure that opens inward along the edge of the bubble-cutting assembly 3, so as to uniformly disperse impurities along the circumferential direction of the bubble-cutting assembly 3 to the edge. There may be multiple impurity discharge passages 31, and the multiple impurity discharge passages 31 are uniformly installed in the axial direction of the bubble-cutting assembly 3 to ensure uniformity of impurity dispersion.

[0063] Furthermore, the protruding structure 33 and the water outlet cover 4 can be enclosed in a conical structure, where the cross-section of the conical structure is triangular. In this case, the minimum height of the protruding structure 33 along the water flow direction is the position where the protruding structure 33 and the water outlet cover 4 come into contact. Alternatively, the protruding structure 33 and the water outlet cover 4 can be enclosed in a pentagonal structure, in which case the minimum height of the protruding structure 33 along the water flow direction is the lower end of the side wall of the protruding structure 33.

[0064] In one embodiment, as shown in Figures 12 to 14, the bubble cutting assembly 3 is recessed in the direction away from the gas-liquid mixing assembly 2 along the water flow direction, forming a recessed structure 32, and the bubble cutting assembly 3 protrudes in the direction approaching the gas-liquid mixing assembly 2, forming a protruding structure 33.

[0065] In other words, the bubble cutting assembly 3 does not have to have only a recessed structure 32 or a protruding structure 33; rather, the bubble cutting assembly 3 may have both a recessed structure 32 and a protruding structure 33. However, since the groove walls of the recessed structure 32 and the side walls of the protruding structure 33 are installed at an inclination with respect to the second direction, the smoothness and reliability of the sliding of impurities are ensured.

[0066] If there is only one protruding structure 33 and one recessed structure 32, it will be understandable that the cross-section of the bubble-cut assembly 3 may be formed into a folded structure.

[0067] In one embodiment, the protruding structure 33 and the recessed structure 32 adjacent to it overlap in at least part.

[0068] The adjacent protruding structure 33 and recessed structure 32 share a common inclined surface; that is, the side wall of the protruding structure 33 becomes the groove wall of the recessed structure 32.

[0069] In one embodiment, as shown in Figures 12 to 14, the recessed structure 32 is installed coaxially with respect to the gas-liquid mixing assembly 2, and the protruding structure 33 is installed in a ring-like manner around the recessed structure 32, or, as shown in Figure 15, the protruding structure 33 is installed coaxially with respect to the gas-liquid mixing assembly 2, and the recessed structure 32 is installed in a ring-like manner around the protruding structure 33.

[0070] As shown in Figures 12 to 14, the recessed structure 32 is installed coaxially with respect to the gas-liquid mixing assembly 2, and the protruding structure 33 is installed annularly around the recessed structure 32, that is, the recessed structure 32 is installed at the center of the bubble-cutting assembly 3. If the bubble-cutting assembly 3 is symmetrical with respect to the axis of the gas-liquid mixing assembly 2, then dividing the bubble-cutting assembly 3 in half corresponds to dividing the bubble-cutting assembly 3 into two radial parts, with each of the two parts having two inclined side walls of one protruding structure 33. This achieves stepwise processing of the radial portion of the bubble-cutting assembly 3, reduces the time it takes for impurities to slide from the top to the bottom of the bubble-cutting assembly 3 along the direction of water flow, and improves the timeliness and effectiveness of impurity removal.

[0071] As shown in Figure 15, the protruding structure 33 is installed coaxially with respect to the gas-liquid mixing assembly 2, and the recessed structure 32 is installed annularly around the protruding structure 33, that is, the protruding structure 33 is installed at the center of the bubble-cutting assembly 3. If the bubble-cutting assembly 3 is symmetrical with respect to the axis of the gas-liquid mixing assembly 2, then dividing the bubble-cutting assembly 3 in half corresponds to dividing the bubble-cutting assembly 3 into two radial parts, with each of the two parts having two inclined side walls of one protruding structure 33. This achieves stepwise processing of the radial portion of the bubble-cutting assembly 3, reduces the time it takes for impurities to slide from the top to the bottom of the bubble-cutting assembly 3 along the direction of water flow, and improves the timeliness and effectiveness of impurity removal.

[0072] In one embodiment, along the second direction, the impurity discharge passage 31 is located at the center of the recessed structure 32, and / or, along the second direction, the impurity discharge passage 31 is located at the position furthest from the center of the protruding structure 33.

[0073] As shown in Figures 12 to 14, when the recessed structure 32 and the gas-liquid mixing assembly 2 are installed coaxially, that is, when the recessed structure 32 is installed in the center of the bubble-cutting assembly 3, by installing the impurity discharge passage 31 in the center of the recessed structure 32, that is, by installing the impurity discharge passage 31 at the position of the maximum depth of the recessed structure 32, a large amount of impurities will gather at the bottom of the groove of the recessed structure 32 along the groove wall of the recessed structure 32. Therefore, the impurity discharge passage 31 is appropriately positioned opposite the location where impurities accumulate in the bubble-cutting assembly 3, and it is ensured that impurities are discharged directly from the impurity discharge passage 31.

[0074] When the recessed structure 32 and the gas-liquid mixing assembly 2 are installed coaxially, and the protruding structure 33 is installed in a ring around the recessed structure 32, the impurity discharge passage 31 is installed at the position furthest from the center of the protruding structure 33, that is, at the position of the minimum height of the protruding structure 33, in other words, the impurity discharge passage 31 is installed at the edge of the protruding structure 33. As a result, many impurities are dispersed along the side walls of the protruding structure 33 to the edge of the protruding structure 33, so that the impurity discharge passage 31 is appropriately facing the impurity dispersion point in the bubble-cutting assembly 3, and it is ensured that impurities are discharged directly from the impurity discharge passage 31.

[0075] As shown in Figure 15, when the protruding structure 33 and the gas-liquid mixing assembly 2 are installed coaxially, that is, when the protruding structure 33 is installed at the center of the bubble-cutting assembly 3, the impurity discharge passage 31 is installed at the position furthest from the center of the protruding structure 33, that is, the impurity discharge passage 31 is installed at the minimum height of the protruding structure 33, or in other words, the impurity discharge passage 31 is installed at the edge of the protruding structure 33. As a result, many impurities are dispersed along the side wall of the protruding structure 33 to the edge of the protruding structure 33, so that the impurity discharge passage 31 is appropriately facing the location where impurities are dispersed in the bubble-cutting assembly 3, and it is ensured that impurities are discharged directly from the impurity discharge passage 31.

[0076] The protruding structure 33 and the gas-liquid mixing assembly 2 are installed coaxially, the recessed structure 32 is installed in a ring around the protruding structure 33, and the impurity discharge passage 31 is installed at the center of the recessed structure 32. In other words, by installing the impurity discharge passage 31 at the maximum depth of the recessed structure 32, many impurities gather along the groove wall of the recessed structure 32 down to the bottom of the groove, the impurity discharge passage 31 is appropriately positioned opposite the location where impurities gather in the bubble-cutting assembly 3, and it is ensured that impurities are discharged directly from the impurity discharge passage 31.

[0077] In such a case, the number and location of the impurity discharge passages 31 may be one or multiple, but it is understandable that one impurity discharge passage 31 may be installed only at the position furthest from the center of the recessed structure 32 or the center of the protruding structure 33, or that multiple impurity discharge passages 31 may be installed at the positions furthest from the center of the recessed structure 32 and the center of the protruding structure 33, respectively.

[0078] In one embodiment, there are multiple protruding structures 33, and recessed structures 32 are located between two adjacent protruding structures 33, and / or there are multiple recessed structures 32, and protruding structures 33 are located between two adjacent recessed structures 32.

[0079] The number of protruding structures 33 and recessed structures 32 may each be multiple, and it can be understood that the protruding structures 33 and recessed structures 32 are fitted together, and that the radii of the protruding structures 33 and recessed structures 32 are different. In this case, the cross-section of the bubble-cutting assembly 3 becomes like a continuous broken line structure, and it is ensured that impurities do not temporarily accumulate at the top of the bubble-cutting assembly 3, but all slide down to the bottom of the bubble-cutting assembly 3.

[0080] If the radius of the bubble-cutting assembly 3 is constant, the greater the number of protruding structures 33 and recessed structures 32, the smaller the inclination angle of the protruding structures 33 and recessed structures 32 along the second direction, that is, the gentler the gradient of the inclined surface, which may affect the sliding speed of impurities. Therefore, it is understandable that the timely discharge of impurities can be ensured by selecting the number of protruding structures 33, the number of recessed structures 32, and the gradient of the protruding structures 33 and the gradient of the recessed structures 32 according to the actual needs, in order to balance the relationship between the number and the gradient.

[0081] In one embodiment, along the direction of water flow, at least a portion of the projection of the gas-liquid mixing assembly 2 covers the projection of the bubble-cutting assembly 3.

[0082] The projection of the gas-liquid mixing assembly 2 covers the projection of the bubble-cutting assembly 3, ensuring that the microbubble assembly and the bubble-cutting assembly 3 are positioned opposite each other, and allowing the microbubble water discharged from the gas-liquid mixing assembly 2 to pass directly through the bubble-cutting assembly 3, thereby achieving filtration of impurities.

[0083] In one embodiment, the bubble cutting assembly 3 comprises a plurality of filter screens 34 stacked and installed along the direction of water flow. Of these, at least some of the filter screens 34 have different mesh counts. The filter screen 34 located in the uppermost layer along the direction of water flow has the maximum mesh count of 200 mesh or more.

[0084] For example, a portion of the filter screen 34, i.e., the uppermost filter screen 34 positioned along the direction of water flow, may be a porous filter screen, while other filter screens 34, i.e., the filter screens 34 in the lower layers than the uppermost layer, may be dense-pore filter screens. Multiple porous filter screens and multiple dense-pore filter screens form a bubble-cutting assembly 3 in which loose and dense layers are alternately stacked, thereby improving the bubble-cutting effect.

[0085] This embodiment further provides a water dispensing device suitable for the technical fields of shower heads, faucets, and toilets, the water dispensing device comprising a microbubble generator.

[0086] The water discharge device provided in this embodiment achieves primary filtration of the water flow along the direction of the water flow by installing a filtration component 1, thereby preventing impurities from entering the microbubble generator. By installing a gas-liquid mixing assembly 2, air is introduced into the gas-liquid mixing assembly 2 and mixed with the water flow to generate bubbles and form bubble water. By installing a bubble cutting assembly 3, the bubbles in the bubble water are cut into fine bubbles to form microbubble water, and the microbubble water removes dirt from small blood vessels and fruits and vegetables with these fine bubbles, improving cleanliness.

[0087] Furthermore, since at least a portion of the bubble cutting assembly 3 forms a first direction and angle, and the angle is set to be less than 90 degrees or greater than 90 degrees, the bubble cutting assembly 3 is installed at an incline rather than horizontally. If impurities remain in the bubble cutting assembly 3, the bubble cutting assembly 3 acts as a guide incline, and when a high-speed jet of water is injected, the impurities slide down along the bubble cutting assembly to the bottom of the bubble cutting assembly in the direction of the water flow. In other words, the impurities accumulate at the bottom of the bubble cutting assembly and do not spread throughout the entire bubble cutting assembly, reducing the risk of clogging of the entire bubble cutting assembly. In addition, since impurities in the microbubbles remain in the bubble cutting assembly 3, an impurity discharge passage 31 is installed in the bubble cutting assembly 3 to discharge the impurities, so that the impurities are discharged from the microbubble generator. By installing the impurity discharge passage 31 along the direction of the water flow so that the direction of the impurity discharge passage 31 is the same as the direction of the water flow, the water jet becomes the power source for the movement of the impurities, making it easier for impurities to be smoothly discharged from the impurity discharge passage 31 and resulting in an excellent impurity removal effect.

[0088] In one embodiment, the water discharge device further comprises a water supply pipe for supplying water flow to a microbubble generator, and the water supply pipe and the microbubble generator are in communication with each other.
