[0030] Furthermore, in the description of the present application, it can be understood that directional terms such as "upper", "lower", "inner", "outer", etc. described in the embodiments of the present disclosure are described from the perspective shown in the accompanying drawings and should not be construed as limitations on the embodiments of the present disclosure. Also, in the context, when referring to one element or feature being connected to the "upper", "lower", or "inner", "outer" of another element(s), it is not only possible to be directly connected to the "upper", "lower", or "inner", "outer" of another element(s), but also possible to be indirectly connected to the "upper", "lower", or "inner", "outer" of another element(s) via an intermediate element.

[0031] One embodiment of the present application provides a microbubble generator. Referring to FIGS. 1 to 3, the microbubble generator includes a filtering component 1, a gas-liquid mixing assembly 2, and a bubble cutting assembly 3. The filtering 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 water discharge direction of the gas-liquid mixing assembly 2 is taken as the first direction. The bubble cutting assembly 3 is used to cut the bubbles in the bubble water into fine bubbles so as to form microbubble water.

[0032] The microbubble generator provided by this embodiment achieves primary filtration of the water flow flowing in the water flow direction by installing the filtering component 1, and avoids impurities from mixing into the microbubble generator. By installing the gas-liquid mixing assembly 2, air is introduced into the gas-liquid mixing assembly 2 and mixed with the water flow to generate bubbles, thereby forming bubble water. By installing the bubble cutting assembly 3, the bubble cutting assembly 3 can cut the bubbles in the bubble water into fine bubbles, forming microbubble water, which can remove the dirt on capillaries and fresh fruits with the microbubble water and improve the cleanliness.

[0033] When the bubble cutting assembly 3 cuts the bubble water, in order to avoid affecting the lifespan of the bubble cutting assembly 3 by causing impurities to remain in the bubble cutting assembly 3 and causing a risk of clogging, as shown in FIGS. 2 to 3, at least a part of the bubble cutting assembly 3 provided by this embodiment forms an angle with the first direction. An impurity discharge passage 31 for discharging impurities in the microbubble water is installed in the bubble cutting assembly 3 along the water flow direction. Among them, the angle is less than 90 degrees or greater than 90 degrees.

[0034] The microbubble generator provided in this embodiment is such that at least a part of the bubble cutting assembly 3 forms an angle with the first direction, and the angle is set to be less than 90 degrees or greater than 90 degrees. As a result, the bubble cutting assembly 3 is not installed horizontally but is installed inclined. When impurities remain in the bubble cutting assembly 3, the bubble cutting assembly 3 serves as a guide inclined surface. When a high-speed jet water flow is sprayed, the impurities slide down along the bubble cutting assembly 3 to the bottom of the bubble cutting assembly 3 along the water flow direction, that is, the impurities gather at the bottom of the bubble cutting assembly 3 and do not spread over the entire bubble cutting assembly 3, reducing the risk of blockage of the entire bubble cutting assembly 3. Also, in order to prevent impurities in the microbubble generator from remaining in the bubble cutting assembly 3, an impurity discharge passage 31 for discharging impurities from the inside of the microbubble bubbler is installed in the bubble cutting assembly 3.

[0035] The impurity discharge passage 31 is installed along the water flow direction so that the impurity discharge passage 31 and the flow direction of the water flow are in the same direction, and the injection of the water flow provides power for the movement of the impurities, making it easy for the impurities to be smoothly discharged from the impurity discharge passage 31 and it can be understood that the impurity removal effect is excellent.

[0036] In addition, when the water flow direction is the vertical direction, the water discharge direction of the gas-liquid mixing assembly 2 may be the vertical direction or may have a certain angle with respect to the vertical direction. When the water discharge direction of the gas-liquid mixing assembly 2 is the vertical direction, the first direction shown in the arrow X direction in FIG. 2 is the water flow direction, and the second direction shown in the arrow Y direction in FIG. 2 is the horizontal direction. At this time, it can be understood that the first direction and the second direction are installed perpendicular to each other. Among them, when the filtering component 1, the gas-liquid mixing assembly 2, and the 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 FIGS. 2 to 4, the filtration component 1 includes a support member and a filtration member. The support member is a filter screen with an annular structure and is used to attach and support the filtration member. At least a part of the filtration member is installed inclined with respect to the second direction.

[0038] In the present application, since the filtration component is installed inclined, when a large amount of impurities remain in the bubble cutting assembly 3, the bubble cutting assembly 3 serves as a guiding inclined surface. When a high-speed jet water flow is injected, the impurities slide down along the bubble cutting assembly 3 to the bottom of the bubble cutting assembly 3 in the water flow direction, that is, the impurities gather at the bottom of the bubble cutting assembly 3 and do not spread over the entire bubble cutting assembly 3, reducing the risk of clogging of the entire bubble cutting assembly 3. The filtration component can be installed horizontally, and by removing the microbubble generator, the impurities gathered on the filtration component can also be washed away. The microbubble generator may not have the filtration component installed.

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

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

[0041] Note that the water discharge surface cover 4 is provided with water discharge holes, and since the water discharge holes communicate with the impurity discharge passage 31, impurities flowing out from the impurity discharge passage 31 are discharged from the water discharge holes, serving as a discharge space for finally discharging the impurities, avoiding clogging of the impurity discharge passage 31, and ensuring the cleanliness inside the microbubble generator.

[0042] In one embodiment, as shown in FIGS. 2 and 3, the gas-liquid mixing assembly 2 includes a flow divider 21 and a mixer 22. The water 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 water discharge surface cover 4 and the mixer 22, and the bubble cutting assembly 3 is installed in the second chamber 200. An air supply passage may be formed between the side wall of the water discharge surface cover 4 and the side wall of the flow divider 21.

[0043] Since the water flow sequentially passes through the first water supply hole 211 and the second water supply hole 221, and the flow area of the second water supply hole 221 is larger than that of the first water supply hole 211, based on Bernoulli's principle, a certain negative pressure is generated in the second water supply hole 221, so that the outside air is sequentially sucked into the second water supply hole 221 after passing through the air supply passage and the first chamber 100, forming a mixed water flow containing the water flow and some bubbles, and the mixed water flow enters the second chamber 200.

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

[0045] By installing the impurity discharge passage 31 at a position where the bubble cutting assembly 3 is at the farthest distance from the gas-liquid mixing assembly 2, that is, by installing the impurity discharge passage 31 at the bottom of the bubble cutting assembly 3 along the water flow direction, impurities slide down along the bubble cutting assembly 3 to the bottom of the bubble cutting assembly 3 along the water flow direction. Therefore, it is possible for the impurity discharge passage 31 to align with the properly slid-down impurities, that is, the impurities and the impurity discharge passage 31 are installed facing each other, ensuring that the impurities completely enter the impurity discharge passage 31. In the flushing by high-speed jet injection, it becomes easier for the impurities to be washed away in the impurity discharge passage 31, and the impurity discharge process is achieved.

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

[0047] The bubble cutting assembly 3 is recessed in a direction away from the gas-liquid mixing assembly 2. Exemplarily, the recessed structure 32 is formed in a flare structure where the large-mouth end is installed toward the gas-liquid mixing assembly 2 and the small-mouth end is installed toward the water discharge surface cover 4. At this time, the two side walls of the recessed structure 32 are installed inclined with respect to the second direction, enabling impurities to slide along the inclined groove walls. The recessed structure 32 serves to accumulate impurities. It can be understood that the impurities do not spread to the side walls and accumulate at the groove bottom of the recessed structure 32 along the groove walls, avoiding wide clogging of the groove walls of the recessed structure 32.

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

[0049] By installing the impurity discharge passage 31 at the position of the maximum depth of the recessed structure 32, that is, by installing the impurity discharge passage 31 at the groove bottom of the recessed structure 32, a large amount of impurities accumulate along the groove wall of the recessed structure 32 to the groove bottom of the recessed structure 32. Therefore, the impurity discharge passage 31 is appropriately opposed to the location where impurities gather in the bubble cutting assembly 3, ensuring that impurities are directly discharged from the impurity discharge passage 31.

[0050] When the recessed structure 32 is a structure symmetric with respect to the axis of the microbubble assembly, at this time, the impurity discharge passage 31 is installed at the center of the recessed structure 32 along the second direction, which corresponds to the impurity discharge passage 31 being installed near the accumulation point, and this can be understood.

[0051] In some embodiments, the recessed structure 32 may be an asymmetric structure with respect to the axis of the microbubble assembly. At this time, the impurity discharge passage 31 may be installed at the lowest position of the recessed structure 32 along the water flow direction.

[0052] In one embodiment, as shown in FIGS. 6 to 8, the impurity discharge passage 31 is a through hole provided in the bubble cutting assembly 3. By directly opening a through hole in the bubble cutting assembly 3, the impurity discharge passage 31 can be formed. The structure is simple, easy to implement, and the manufacturing cost is low.

[0053] Specifically, the cross-sectional shape of the through hole is any one of a circle, an arc, a triangle, and a polygon. In this embodiment, the specific shape of the through hole, that is, the impurity discharge passage 31, is not limited and can be adjusted according to the actual needs 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 gather uniformly at the center.

[0055] Note that the recessed structure 32 and the water discharge surface cover 4 can be surrounded by a conical structure, and the cross-section of the conical structure is a triangular structure. At this time, the position of the maximum depth of the recessed structure 32 along the water flow direction is the position where the recessed structure 32 and the water discharge surface cover 4 are in contact. The recessed structure 32 and the water discharge surface cover 4 can also be surrounded by a frustum of a cone structure. The position of the minimum height of the recessed structure 32 along the water flow direction is the bottom surface of the frustum of a cone structure along the water flow direction. At this time, the bottom surface can provide a force to support the bubble cutting assembly 3 with the water discharge surface cover 4, and can provide a large installation space for the impurity discharge passage 31.

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

[0057] The bubble cutting assembly 3 protrudes in a direction approaching the gas-liquid mixing assembly 2. Exemplarily, the protruding structure 33 is formed in a flare structure in which the large mouth end is installed toward the water discharge surface cover 4 and the small mouth end is installed toward the gas-liquid mixing assembly 2. At this time, the two side walls of the protruding structure 33 are provided to be inclined with respect to the second direction, so that impurities can slide along the inclined side walls, and the protruding structure 33 functions to disperse the impurities. It can be understood that the impurities do not spread over the entire side wall, but are dispersed along the side wall to the bottom of the protruding structure 33, avoiding wide clogging of the side wall of the protruding structure 33.

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

[0059] Since many impurities are dispersed along the side wall of the protruding structure 33 to the edge of the protruding structure 33, by installing the impurity discharge passage 31 at the position of 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 can be appropriately opposed to the impurity dispersion location in the bubble cutting assembly 3, ensuring that the impurities are directly discharged from the impurity discharge passage 31.

[0060] When the protruding structure 33 has a symmetrical structure with respect to the axis of the microbubble assembly, at this time, it can be understood that the impurity discharge passage 31 exists at a position along the second direction where the protruding structure 33 is at the farthest distance from its center, which corresponds to the impurity discharge passage 31 being installed near the dispersion location.

[0061] In some embodiments, the protruding structure 33 may have an asymmetrical structure with respect to the axis of the microbubble assembly, but at this time, it can be understood that the impurity discharge passage 31 may be installed at the lowest position of the protruding structure 33 along the water flow direction.

[0062] As shown in FIGS. 9 to 11, the impurity discharge passage 31 installed in the protruding structure 33 may be an arc-shaped hole structure corresponding to a semi-circular hole structure that opens inward along the edge of the bubble cutting assembly 3 so as to uniformly disperse the impurities along the circumferential direction of the bubble cutting assembly 3 to the edge. Among them, the number of the impurity discharge passages 31 may be plural, and the plural impurity discharge passages 31 are uniformly installed in the axial direction of the bubble cutting assembly 3 to ensure the uniformity of the dispersion of the impurities.

[0063] It should be noted that the protruding structure 33 and the water discharge surface cover 4 can be surrounded by a conical structure, and the cross-section of the conical structure is a triangular structure. At this time, the position of the minimum height of the protruding structure 33 along the water flow direction is the position where the protruding structure 33 and the water discharge surface cover 4 contact. Also, the protruding structure 33 and the water discharge surface cover 4 can be surrounded by a pentagonal structure. At this time, the position of 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 FIGS. 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, and a recessed structure 32 is formed. The bubble cutting assembly 3 protrudes in the direction approaching the gas-liquid mixing assembly 2, and a protruding structure 33 is formed.

[0065] In other words, the bubble cutting assembly 3 does not only have the recessed structure 32 or the protruding structure 33, but the bubble cutting assembly 3 may also have both the recessed structure 32 and the protruding structure 33. However, since the groove wall of the recessed structure 32 and the side wall of the protruding structure 33 are respectively installed inclined with respect to the second direction, the smoothness and certainty of the sliding of impurities are ensured.

[0066] When the number of the protruding structure 33 and the recessed structure 32 is one, it can be understood that the cross-section of the bubble cutting assembly 3 may be formed into a folding structure.

[0067] In one embodiment, at least a part of the protruding structure 33 and the recessed structure 32 adjacent thereto overlap.

[0068] The adjacent protruding structure 33 and recessed structure 32 have a shared 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 FIGS. 12 to 14, the recessed structure 32 is coaxially installed with respect to the gas-liquid mixing assembly 2, the protruding structure 33 is installed in a surrounding annular shape around the recessed structure 32, or, as shown in FIG. 15, the protruding structure 33 is coaxially installed with respect to the gas-liquid mixing assembly 2, and the recessed structure 32 is installed in a surrounding annular shape around the protruding structure 33.

[0070] As shown in FIGS. 12 to 14, the recessed structure 32 is coaxially installed with respect to the gas-liquid mixing assembly 2, and the protruding structure 33 is installed in an annular shape around the recessed structure 32, that is, the recessed structure 32 is installed at the center of the bubble cutting assembly 3. When the bubble cutting assembly 3 is symmetric with respect to the axis of the gas-liquid mixing assembly 2, half of the bubble cutting assembly 3 corresponds to dividing the bubble cutting assembly 3 into two in the radial direction and equipping the two parts with two inclined side walls of one protruding structure 33, achieving a step-by-step treatment for the radial part of the bubble cutting assembly 3, reducing the time for impurities to slide from the upper part to the bottom part of the bubble cutting assembly 3 along the water flow direction, and improving the timeliness and effect of impurity discharge.

[0071] As shown in Fig. 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. When the bubble cutting assembly 3 is symmetric with respect to the axis of the gas-liquid mixing assembly 2, half of the bubble cutting assembly 3 corresponds to dividing the bubble cutting assembly 3 into two in the radial direction and equipping the two parts with two inclined side walls of one protruding structure 33. The step-by-step treatment of the radial part of the bubble cutting assembly 3 is achieved, reducing the time for impurities to slide from the upper part to the bottom of the bubble cutting assembly 3 along the water flow direction, and improving the timeliness and effect of impurity discharge.

[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 a position with the farthest distance from the center of the protruding structure 33.

[0073] As shown in Figs. 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 at the center of the bubble cutting assembly 3, by installing the impurity discharge passage 31 at 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 gather at the groove bottom of the recessed structure 32 along the groove wall of the recessed structure 32. Therefore, the impurity discharge passage 31 is appropriately opposed to the impurity gathering location in the bubble cutting assembly 3, ensuring that the impurities are directly discharged from the impurity discharge passage 31.

[0074] When the recessed structure 32 and the gas-liquid mixing assembly 2 are coaxially installed and the protruding structure 33 is annularly installed around the recessed structure 32, the impurity discharge passage 31 is installed at a position farthest from the center of the protruding structure 33, that is, by installing the impurity discharge passage 31 at the position of the minimum height of the protruding structure 33. In other words, by installing the impurity discharge passage 31 at the edge of the protruding structure 33, a large number of impurities are dispersed along the side wall of the protruding structure 33 to the edge of the protruding structure 33. Therefore, the impurity discharge passage 31 is appropriately opposed to the impurity dispersion location in the bubble cutting assembly 3, ensuring that impurities are directly discharged from the impurity discharge passage 31.

[0075] As shown in FIG. 15, when the protruding structure 33 and the gas-liquid mixing assembly 2 are coaxially installed, 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 a position farthest from the center of the protruding structure 33, that is, by installing the impurity discharge passage 31 at the position of the minimum height of the protruding structure 33. In other words, by installing the impurity discharge passage 31 at the edge of the protruding structure 33, a large number of impurities are dispersed along the side wall of the protruding structure 33 to the edge of the protruding structure 33. Therefore, the impurity discharge passage 31 is appropriately opposed to the impurity dispersion location in the bubble cutting assembly 3, ensuring that impurities are directly discharged from the impurity discharge passage 31.

[0076] When the protruding structure 33 and the gas-liquid mixing assembly 2 are coaxially installed and the recessed structure 32 is annularly installed around the protruding structure 33, by installing the impurity discharge passage 31 at 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 number of impurities gather along the groove wall of the recessed structure 32 to the groove bottom of the recessed structure 32. The impurity discharge passage 31 is appropriately opposed to the impurity gathering location in the bubble cutting assembly 3, ensuring that impurities are directly discharged from the impurity discharge passage 31.

[0077] In such a case, the number and position of the impurity discharge passage 31 may be one or plural. However, one impurity discharge passage 31 may be installed only at the center of the recessed structure 32 or at the position farthest from the center of the protruding structure 33, or it will be understandable that the plurality of impurity discharge passages 31 are respectively installed at the center of the recessed structure 32 and at the position farthest from the center of the protruding structure 33.

[0078] In one embodiment, the number of the protruding structures 33 is plural, the recessed structure 32 is located between two adjacent protruding structures 33, and / or the number of the recessed structures 32 is plural, and the protruding structure 33 is located between two adjacent recessed structures 32.

[0079] It will be understandable that the number of the protruding structures 33 and the recessed structures 32 may each be plural, the protruding structures 33 and the recessed structures 32 are fitted to each other, and the radii of the protruding structures 33 and the recessed structures 32 are different from each other. At this time, the cross section of the bubble cutting assembly 3 is like a continuous broken line structure, and it is ensured that impurities do not temporarily gather at the upper part of the bubble cutting assembly 3 and all slide down to the bottom of the bubble cutting assembly 3.

[0080] When the radius of the bubble cutting assembly 3 is a certain value, the larger the number of the protruding structures 33 and the recessed structures 32, the smaller the inclination angle of the protruding structures 33 and the recessed structures 32 along the second direction, that is, the gentler the gradient of the inclined surface, so it may affect the sliding speed of the impurities. Therefore, it will be understandable that the timeliness of impurity discharge is ensured by selecting the number of the protruding structures 33, the number of the recessed structures 32, the gradient of the protruding structures 33, and the gradient of the recessed structures 32 according to actual needs so as to balance the relationship between the number and the gradient.

[0081] In one embodiment, along the water flow direction, at least a part 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 covering the projection of the bubble cutting assembly 3 ensures the opposed installation of the microbubble assembly and the bubble cutting assembly 3, allows the microbubble water discharged from the gas-liquid mixing assembly 2 to directly pass through the bubble cutting assembly 3, and achieves the filtration of impurities.

[0083] In one embodiment, the bubble cutting assembly 3 includes a plurality of filter screens 34 stacked along the water flow direction. Among them, at least some of the plurality of filter screens 34 have different mesh numbers. The mesh number of the filter screen 34 arranged in the uppermost layer along the water flow direction is the largest and is 200 meshes or more.

[0084] For example, a part of the filter screen 34, that is, the filter screen 34 arranged in the uppermost layer along the water flow direction, may be a porous filter screen, while other filter screens 34, that is, the filter screens 34 in the lower layer than the uppermost layer, may be a dense-hole filter screen. A bubble cutting assembly 3 with porous layers and dense layers alternately stacked is formed by a plurality of porous filter screens and a plurality of dense-hole filter screens, improving the effect of bubble cutting.

[0085] This embodiment further provides a water discharging device suitable for the technical fields of shower heads, faucets, and toilets. The water discharging device includes a microbubble generating device.

[0086] The water discharging device provided by this embodiment realizes primary filtration of the water flow flowing along the water flow direction by installing the filtering component 1, avoiding impurities from entering the microbubble generating device. By installing the gas-liquid mixing assembly 2, air is introduced into the gas-liquid mixing assembly 2, mixed with the water flow to generate bubbles, and bubble water is formed. By installing the bubble cutting assembly 3, the bubbles in the bubble water are cut into fine bubbles to form microbubble water, and the microbubble water removes the dirt on capillaries and fruits with the fine bubbles, improving the cleanliness.

[0087] In addition, at least a part of the bubble cutting assembly 3 forms an angle with the first direction, and the angle is set to be less than 90 degrees or greater than 90 degrees. Therefore, the bubble cutting assembly 3 is not installed horizontally but is installed inclined. When impurities remain in the bubble cutting assembly 3, the bubble cutting assembly 3 serves as a guiding inclined surface. When a high-speed jet water flow is sprayed, the impurities slide down along the bubble cutting assembly and reach 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. Also, since impurities in the microbubbles remain in the bubble cutting assembly 3, by installing an impurity discharge passage 31 for discharging impurities in the bubble cutting assembly 3, the impurities are discharged from the microbubble generator. By installing the impurity discharge passage 31 along the water flow direction so that the flow direction of the impurity discharge passage 31 is the same as that of the water flow, the spraying of the water flow becomes the driving force for the movement of the impurities, facilitating the smooth discharge of the impurities from the impurity discharge passage 31 and having an excellent impurity removal effect.

[0088] In one embodiment, the water spraying device further includes a water supply pipe for supplying water flow to the microbubble generator, and the water supply pipe is in communication with the microbubble generator.
