[0048] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0049] In the various specific technical features described in the specific embodiments, they can be combined in any suitable manner without conflict. For example, different embodiments and technical solutions can be formed by combining different specific technical features. To avoid unnecessary repetition, various possible combination methods of the specific technical features in the present invention will not be described separately.

[0050] In the following description, the terms "first / second / ..." involved are only used to distinguish different objects and do not indicate that there are the same or related relationships between the objects. It should be understood that the orientation descriptions "above", "below", "outside", "inside" involved are all orientations in the normal use state, and the "left" and "right" directions represent the left and right directions shown in the specific corresponding schematic diagram, which may or may not be the left and right directions in the normal use state. The direction indicated by the arrow in the figure is the flow direction of the fluid.

[0051] It should be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or apparatus comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or elements inherent to such process, method, article or apparatus. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or apparatus comprising that element. "Plurality" means greater than or equal to two.

[0052] An embodiment of the present invention provides a sterilization device, which can be applied to washing devices such as laundry treatment equipment, dishwashers and fruit and vegetable washing machines. It should be noted that the application scenario type of the embodiment of the present invention does not limit the sterilization device of the embodiment of the present invention.

[0053] An embodiment of the present invention provides a sterilization device, as Figure 1 and Figure 2 shown, for being disposed in the fluid passage 1 to release a disinfection substance into the fluid to make the fluid have a disinfection effect. Among them, the fluid passage 1 can be a spatial area for fluid to pass through in various washing devices. The sterilization device includes a housing 2 and a moving body 3. A cavity 21 for placing disinfection particles 4 is provided in the housing 2. It should be noted that the cavity 21 is not completely closed, and the cavity 21 can communicate with the outside of the housing 2, so that the fluid outside the housing 2 can enter the cavity 21. The fluid impacts the disinfection particles 4 in the cavity 21, and the disinfection particles 4 release the disinfection substance and dissolve in the fluid. The fluid with the disinfection substance can flow out of the cavity 21 to the outside of the housing 2 for disinfection.

[0054] It should be noted that the fluid in the fluid passage 1 represents an object that can flow. The fluid in the embodiment of the present invention can be a liquid. Of course, it can also be a mixture of gas and liquid. Among them, the liquid includes but is not limited to tap water, pure water and a mixed liquid with a washing effect.

[0055] The disinfection particle 4 is a particle that can release the disinfection substance at a relatively slow speed. The composition of the disinfection particle 4 includes but is not limited to solid compositions such as bleach, bactericide and detergent. The embodiment of the present invention does not limit the shape, size and components of the disinfection particle 4, nor does it limit the specific speed value of the relatively slow release speed, as long as the content of the substance released within the set time meets the actual requirements. For example, 0.1-1 gram of the disinfection substance is released within 1 minute. Of course, it can also be another release speed as long as it can meet the actual requirements.

[0056] Combined with Figure 1 and Figure 2As shown, the moving body 3 is at least partially disposed within the cavity 21, and the moving body 3 is movable relative to the receiving body 2. That is to say, a part of the moving body 3 can be disposed within the cavity 21, and another part can be disposed outside the cavity 21; the moving body 3 can also be entirely disposed within the cavity 21. The embodiments of the present invention do not limit the specific positional relationship between the moving body 3 and the cavity 21, as long as the moving body 3 is movable relative to the receiving body 2 and at least a part thereof is located within the cavity 21 to drive the movement of the disinfection particles 4.

[0057] The fluid within the fluid passage 1 has a certain kinetic energy and potential energy during the movement process. During the contact process between the fluid and the moving body 3, at least part of the energy of the fluid will be transferred to the moving body 3, so that the moving body 3 can move relative to the receiving body 2. Among them, the receiving body 2 can be arranged to be relatively stationary with respect to the fluid passage 1.

[0058] The movement of the moving body 3 can drive the disinfection particles 4 within the cavity 21 to move relative to each other, thereby driving one or more of the disinfection particles 4, the inner side surface of the receiving body 2, and the outer side surface of the moving body 3 to come into contact and friction with each other, thereby accelerating the speed at which the disinfection particles 4 release the disinfection substance. For example, the movement of the moving body 3 can stir each of the disinfection particles 4 that was originally stationary relative to the receiving body 2 within the cavity 21, causing the relative positions of at least some of the disinfection particles 4 to change, so that the disinfection particles 4 come into contact and friction with each other; of course, during the movement of the disinfection particles 4, the relative positions between the disinfection particles 4 and the surface of the moving body 3 and the inner side surface of the receiving body 2 will also change, resulting in contact friction.

[0059] Among them, the movement mode of the moving body 3 includes various types. For example, the moving body 3 can translate relative to the receiving body 2 along a set direction; the moving body 3 can also rotate relative to the receiving body 2 around a set direction; the moving body 3 can also rotate around a set direction relative to the receiving body 2 and translate along the set direction; the embodiments of the present invention do not limit this.

[0060] In the embodiments of the present invention, the sterilization device is disposed within the fluid passage, the moving body is at least partially disposed within the cavity of the receiving body, and the moving body is movable relative to the receiving body. Through the movement of the moving body at least partially disposed inside the receiving body, the disinfection particles are driven to move. The disinfection particles can rub against the moving body, the receiving body, and other disinfection particles, which is conducive to the release of the disinfection substance and improves the release speed of the disinfection substance; moreover, the movement of the moving body is realized by the impact of the fluid in the fluid passage, so there is no need to soak the disinfection particles, which is conducive to reducing the loss of the disinfection substance and thus reducing the cost.

[0061] In some embodiments, such as Figure 2As shown, a part of the moving body 3 is disposed inside the cavity 21, and another part of the moving body 3 is disposed outside the cavity 21. The moving body 3 includes a driving part 31 and a driven part 32. The driving part 31 is disposed outside the cavity 21, and the driven part 32 is fixedly connected to the driving part 31 and extends into the cavity 21. It should be noted that there are various forms of connection between the driving part 31 and the driven part 32. For example, the driving part 31 and the driven part 32 can be detachably fixedly connected by means of a clamping structure or the like; another example is that the driving part 31 and the driven part 32 can be permanently fixedly connected by means of integral forming such as welding and injection molding. The specific connection manner between the driving part 31 and the driven part 32 in the embodiments of the present invention is not limited, as long as the driven part 32 can be fixedly connected to the driving part 31 in a relatively stationary state.

[0062] As Figure 2 As shown, the driving part 31 is disposed outside the cavity 21. The driving part 31 can be directly in contact with the fluid in the fluid passage 1. The liquid in the fluid passage 1 moves in a set direction. The moving fluid has a certain kinetic energy and potential energy. During the process of the fluid contacting the driving part 31, at least part of the energy of the fluid will be transferred to the driving part 31, thereby driving the driving part 31 to move. The driving part 31 can drive the driven part 32 to move. Since the driven part 32 extends into the cavity 21, the moving driven part 32 can rub against the disinfection particles 4 in the cavity 21 and drive the disinfection particles 4 to move. The disinfection particles 4 subjected to the frictional force will also have relative movement with other disinfection particles 4, thereby realizing the friction between the disinfection particles 4 and the disinfection particles 4; at the same time, the moving disinfection particles 4 may also rub against the inner wall surface of the container 2; therefore, the movement of the disinfection particles speeds up the speed of the disinfection particles 4 releasing the disinfection substance.

[0063] In the embodiments of the present invention, the driving part is disposed outside the cavity, so that the driving part can be directly in contact with the fluid in the fluid passage, enabling the driving part to receive more energy, thereby improving the rotation efficiency of the driven part; on the other hand, the driven part extends into the cavity, and the moving driven part is directly in contact with the disinfection particles, so that more energy can be converted into the disinfection particles, thereby improving the efficiency of the disinfection particles releasing the disinfection substance due to friction, and further improving the disinfection effect of the disinfection device.

[0064] The following describes the form of the rotatable connection between the driven part 32 and the container 2. As Figure 2As shown, the driven part 32 can rotate relative to the housing 2 about a certain rotation axis. When the driven part 32 has an axisymmetric structure, this rotation axis is the axis of symmetry of the driven part; and the degrees of freedom of the driven part 32 and the housing 2 in the axial direction of the rotation axis are restricted. That is to say, the driven part 32 and the housing 2 cannot move relative to each other in the axial direction, or even if relative movement occurs, the range of relative movement is less than a set value. For example, the set value is 5 mm, so as to cover the cases of machining and installation errors.

[0065] In some embodiments, as Figure 2 shown, the driving part 31 includes a rotating body 311 and blades 312. The rotating body 311 extends along a first direction ( Figure 2 shown as the left - right direction), the outer surface of the rotating body 311 is provided with a plurality of blades 312, and the plurality of blades 312 are arranged at intervals around the first direction ( Figure 2 shown as the left - right direction) on the outer surface of the rotating body 311.

[0066] It should be noted that there are various forms of the arrangement of the blades 312. In the embodiments of the present invention, in combination with Figure 1 shown, the length direction of the blade 312 forms a set angle θ with the first direction, and the set angle θ is greater than or equal to 0 degrees and less than or equal to 45 degrees. Figure 1 and Figure 2 shown, in the embodiment, the set angle θ is approximately 30 degrees, the movement direction of the fluid is consistent with the length direction of the rotating shaft 321, so that the water - facing surface 312a of the blade 312 forms an acute angle with the movement direction of the fluid. Among them, the blade 312 can have multiple surfaces, and the water - facing surface 312a refers to the surface of the blade 312 opposite to the movement direction of the fluid, and the surface that the fluid flows towards and impacts on the blade is the water - facing surface. Since the extension direction of the rotating body can be consistent with the axis of the fluid passage, it can be approximately considered that the extension direction of the rotating body is the movement direction of the fluid. In this embodiment, by setting the angle between the extension direction of the blade and the extension direction of the rotating body, that is, setting the angle between the water - facing surface and the fluid flow direction, it is beneficial to increase the impact force of the fluid on the blade, increase the conversion of fluid energy into the driving force for the driving part 31, and drive the driving part 31 to rotate.

[0067] By setting the set angle between the water - facing surface of the blade and the first direction as an acute angle, the angle between the fluid impact direction and the direction of the water - facing surface of the blade receiving the water flow impact is restricted to a larger angle, so that the positive pressure generated by the impact force of the water flow on the water - facing surface of the blade is larger, and correspondingly, a larger thrust and / or torque is generated on the blade, which is beneficial to driving the driving part to rotate. It can be understood that the blade can be a sheet - like structure with a relatively thin thickness, so the blade can be approximately regarded as a two - dimensional surface, and this surface can be a plane or a curved surface.

[0068] AsFigure 3 As shown, the driven part 32 is connected to the first end 311a ( Figure 3 as shown, the right end in the left - right direction) of the rotating body 311 in the first direction ( Figure 3 as shown). Under the action of the fluid impact in the fluid passage 1 on the blade 312, the blade 312 can drive the rotating body 311 to rotate around the first direction, and the driven part 32 connected to the first end 311a of the rotating body 311 can follow the rotating body 311 to rotate around the first direction.

[0069] In some embodiments, as Figure 3 shown, the cross - sectional area of at least part of the rotating body 311 increases as it approaches the driven part 32. It should be noted that the first direction is the length direction of the rotating body 311, and the cross - sectional area refers to the area of the cross - section (perpendicular to the Figure 3 section described) of the rotating body 311 that is perpendicular to the first direction. In the case where the rotating body 311 is axially symmetrically arranged along the first direction, Figure 3 the length change of the rotating body 311 in the Figure 3 up - down direction as shown can be used to characterize the change in the cross - sectional area of the rotating body 311. The rotating body 311 has opposite ends in the first direction. The first end 311a of the rotating body 311 is connected to the driven part 32, and the other end of the rotating body 311 far from the first end 311a can be defined as the second end 311b. From the second end 311b to the first end 311a, the cross - sectional area of the rotating body 311 increases.

[0070] It should be noted that the rotating body 311 in the embodiments of the present invention does not require to be a regular cone or pyramid. It can be that the cross - sectional area gradually increases from the second end 311b to the first end 311a; it can also be that the cross - sectional area gradually increases from the second end 311b to a certain intermediate position in the length direction and then remains unchanged from this intermediate position to the first end 311a; it can also be that there are multiple intermediate positions in the length direction, and the second end 311b to the first end 311a are successively divided into several segments in the length direction, and the cross - sectional area of each segment gradually increases or remains unchanged; among them, in the region where the cross - sectional area gradually increases, the taper of this region can be constant or variable. The rotating body 311 can be similar in shape to a cone, a frustum of a cone, or a mixture of a cone and a frustum.

[0071] In some embodiments, as Figure 3 shown, the cross - sectional area of the rotating body 311 gradually increases from the second end 311b to a certain intermediate position in the length direction and then remains unchanged from this intermediate position to the first end 311a.

[0072] Among them, the rotating body 311 includes in the first direction ( Figure 3A conical body 311c and a cylindrical body 311d connected in sequence in the left - right direction (as shown). The first end 311a of the rotating body 311 is the end of the cylindrical body 311d far from the conical body 311c, and the top of the conical body 311c is the second end 311b of the rotating body 311 in the first direction. The cross - sectional area of the conical body 311c gradually increases from the second end 311b far from the cylindrical body 311d to the end close to the cylindrical body 311d. It should be noted that gradually increasing means that the cross - sectional area monotonically increases from the second end 311b to the end close to the cylindrical body 311d. The slope of the surface of the conical body 311c in the first direction can be a fixed value, and the curvature value of the surface of the conical body 311c has no obvious mutation; it can also be that the slope of the surface of the conical body 311c changes. The cross - sectional area of the cylindrical body 311d remains unchanged from the end close to the conical body 311c to the first end 311a. A plurality of blades 312 are arranged on the side wall of the cylindrical body 311d.

[0073] In the embodiment of the present invention, by arranging a conical body and a cylindrical body connected in sequence on the rotating body, the second end of the rotating body is the end of the cylindrical body far from the conical body, and the first end of the rotating body is the top of the conical body. When the fluid in the fluid passage passes through the conical body in sequence, the area for the fluid to pass through in the fluid passage gradually becomes smaller. According to Bernoulli's principle, when the cross - sectional area of the fluid passage decreases, the flow velocity of the fluid increases, increasing the kinetic energy of the fluid. Then, when the fluid impacts the blades arranged on the cylindrical body, the flow velocity is relatively large, thereby increasing the rotation speed of the blades.

[0074] In some embodiments, as Figure 3 shown, the driven part 32 includes a rotating shaft 321. The rotating shaft 321 can be an elongated rod - shaped object extending in the first direction ( Figure 3 the left - right direction as shown). It can be understood that the rotating shaft 321 has opposite ends in the first direction. One end of the rotating shaft 321 is connected to the first end 311a of the rotating body 311, and the other end of the rotating shaft 321 is arranged in the cavity 21. The rotating shaft 321 is rotatably connected to the accommodating body 2. Among them, the length of the rotating shaft 321 arranged in the cavity 21 is much greater than the length arranged outside the cavity 21. According to the principle of the lever, the contact part of the rotating shaft 321 and the accommodating body 2 can be regarded as the fulcrum. One end of the rotating shaft 321 arranged outside the cavity 21 is connected to the first end 311a of the rotating body 311. Since the rotating body 311 has a certain gravity, by setting the length of the rotating shaft 321 in the cavity 21 to be much greater than the length outside the cavity 21, it is beneficial to improve the stability of the connection between the rotating shaft 321 and the accommodating body 2. In some embodiments, as Figure 3 shown, the ratio of the length L1 of the rotating shaft 321 arranged in the cavity 21 to the length L2 of the rotating shaft 321 arranged outside the cavity 21 can be greater than a set value. For example, the set value is 4.

[0075] In some embodiments, as Figure 3 shown, the driven part 32 further includes a stirring member 322. The stirring member 322 is disposed in the cavity 21 and is connected to the rotating shaft 321. When the driving part 31 drives the rotating shaft 321 to rotate, the stirring member 322 on the rotating shaft 321 will move synchronously with the rotating shaft 321. It should be noted that the stirring member 322 can be a regular structure such as a rod-shaped body, a cone-shaped body, a spherical body, etc., and the stirring member can also be an irregular structure such as a tree branch shape. The embodiments of the present invention do not limit the shape of the stirring member 322, as long as the stirring member 322 can rotate with the rotating shaft and drive the disinfection particles 4 in the cavity 21 to move. By providing a stirring member on the rotating shaft in the embodiments of the present invention, the contact area with the disinfection particles can be increased, which is beneficial to the movement of the disinfection particles in the cavity and the friction between them, thereby improving the speed at which the disinfection particles release the disinfection substance.

[0076] In some embodiments, as Figure 3 shown, the stirring member 322 is set as a rod-shaped body. The rod-shaped body represents a slender rod-shaped structure, and the rod-shaped body can be a solid structure or a hollow structure. The length direction of the rod-shaped body is substantially perpendicular to the first direction. It should be noted that substantially perpendicular includes the case where the included angle between the length direction of the rod-shaped body and the first direction is not strictly 90 degrees. It can be considered that the included angle between the two directions greater than 80 degrees belongs to substantially perpendicular, so as to cover the cases of processing and installation errors. By setting the stirring member as a rod-shaped body in the embodiments of the present invention, the structure is simple and the manufacturing is convenient; by making the length direction of the rod-shaped body perpendicular to the first direction, the rod-shaped body can not only stir the disinfection particles in the cavity, but also not get stuck with the disinfection particles in the cavity, thereby improving the rotation efficiency of the driven part.

[0077] In some embodiments, as Figure 3 shown, a plurality of stirring members 322 are provided. The plurality of stirring members 322 are spaced along the circumferential and / or axial directions of the rotating shaft 321. Among them, the axial direction of the stirring member 322 is parallel to the length direction of the stirring member 322, and this length direction can be the first direction ( Figure 3The "left - right direction" mentioned herein, of course, the first direction is not limited to the direction of a certain straight line, but can be the direction of a group of parallel lines. For example, the first direction is the left - right direction and is not limited to the direction of a certain straight line extending left - right. The circumferential direction represents the direction around the axial direction. In the embodiments of the present invention, there are various forms in which multiple stirring members 322 are arranged around the rotating shaft 321. For example, multiple stirring members 322 can be arranged at intervals along the circumferential direction of the rotating shaft 321; multiple stirring members 322 can also be arranged at intervals along the axial direction of the rotating shaft 321; multiple stirring members can also be arranged at intervals both along the circumferential direction and the axial direction of the rotating shaft; in the case of arranging multiple stirring members, whether circumferentially or axially, the multiple rotating shafts are arranged in a cross - setting manner, so as to improve the stirring effect of the entire driven part. In addition, the extension lengths of the multiple rod - shaped stirring members 322 can be the same or different.

[0078] In some embodiments, as Figure 3 shown, the accommodating body 2 includes a side wall 22 and an end wall 23. The side wall 22 extends along the first direction ( Figure 1 the left - right direction as shown), the side wall 22 has opposite ends in the first direction, and the end wall 23 is provided at both ends of the side wall 22 in the first direction, so that the side wall 22 and the end wall 23 enclose a cavity 21 inside the accommodating body 2. It should be noted that the end wall 23 in the embodiments of the present invention can be a flat plate member, that is, all points on the upper surface of the end wall 23 are in the same plane; in other embodiments, the end wall 23 can be a curved surface member, that is, all points on the surface of the end wall 23 may not be in a plane.

[0079] As Figure 3 shown, in the embodiments of the present invention, the two opposite ends of the end wall 23 in the first direction are respectively a first end wall 231 and a second end wall 232. Among them, the first end wall 231 is closer to the driving part 31 than the second end wall 232, and the rotating shaft 321 passes through the first end wall 231 and is rotatably connected to the second end wall 232.

[0080] In some embodiments, as Figure 3As shown, the second end wall 232 forms a boss 2321 protruding towards the cavity 21. The embodiments of the present invention do not limit the shape of the boss, and the boss can be a cylindrical boss, a conical boss or other structures. The boss 2321 is provided with a groove 2322 recessed inwardly. The shape of the groove can be a circular groove, a conical groove, a cylindrical groove or the like. The groove 2322 can be rotatably connected to the rotating shaft 321. The above-mentioned rotatable connection can be understood as that the groove 2322 and the rotating shaft 321 are not directly connected, but the rotating shaft 321 is defined within the groove 2322, and the rotating shaft 321 remains in contact with the surface of the groove 2322. Wherein, the outer diameter of the rotating shaft 321 can be less than or equal to the inner diameter of the groove 2322, so that the rotating shaft 321 can partially extend into the groove 2322 and abut against the wall surface of the groove 2322. The wall surface of the groove 2322 can play a supporting and limiting role on the rotating shaft 321 in the vertical direction, but the groove 2322 does not affect the circumferential movement of the rotating shaft 321 within the groove 2322.

[0081] In the embodiments of the present invention, by providing a boss on the second end wall and a groove within the boss, and the rotating shaft is rotatably connected to the groove. On the one hand, the structure is simple, and the groove can play a limiting and supporting role on the rotating shaft; on the other hand, it is beneficial to reduce the difficulty of direct cooperation between the rotating shaft and the second end wall, and reduce the processing difficulty of the second end wall.

[0082] In some embodiments, as Figure 3 shown, the groove 2322 is a conical groove with an opening facing the cavity 21. The conical groove means that the wall surface of the groove 2322 has a certain slope, and the opening of the groove 2322 gradually decreases from the end close to the first end wall 231 to the end close to the second end wall 232. The conical groove is symmetric with respect to the first direction. It can be understood that the conical groove can be symmetrically arranged relative to the axial direction of the rotating shaft. Since the rotating shaft 321 is provided as a rod-shaped object, when the groove 2322 is provided as a conical groove, the end of the rotating shaft 321 does not completely fit with the surface of the conical groove, and the contour line of the end of the rotating shaft contacts the inner wall surface of the conical groove. In this state, it can be generally regarded that the side wall is in line contact with the end of the rotating shaft.

[0083] In the embodiments of the present invention, by setting the groove as a conical groove, the rotating shaft and the groove are in line contact, which not only satisfies the limiting and supporting functions of the groove on the rotating shaft in the vertical direction, but also can reduce the contact resistance between the groove and the rotating shaft, reduce the energy consumed by the rotating shaft to overcome the frictional force, so that the rotating shaft can convert more of the power received from the active part into the energy of the rotation of the rotating shaft, thereby improving the rotation efficiency of the rotating shaft.

[0084] In some embodiments, as Figure 3As shown, the driven part 32 further includes a limiting member 323. The limiting member 323 is sleeved on the rotating shaft 321, and the outer surface of the limiting member 323 abuts against the first end wall 231. In the embodiment of the present invention, one end of the rotating shaft 321 abuts against the groove 2322, and the limiting member 323 is arranged in the middle of the rotating shaft 321 to position the rotating shaft 321 relative to the accommodating body 2 in the first direction, reducing the risk of the rotating shaft 321 translating relative to the accommodating body 2 in the first direction, which is beneficial to keeping the rotating shaft 421 and the accommodating body relatively stationary in the first direction.

[0085] In some embodiments, as Figure 3 and Figure 4 shown, a through conical hole 2311 is provided on the first end wall 231. The cross-sectional area of the conical hole 2311 gradually increases in the first direction from the side far from the second end wall 232 to the other side ( Figure 4 from left to right in

[0086] which can be approximately regarded as the direction of fluid flowing into the cavity 21). In the embodiment of the present invention, by providing the conical hole 2311 on the first end wall 231, the rotating shaft 321 passes through the conical hole 2311, and the limiting member 323 on the rotating shaft 321 contacts the conical hole 2311. The limiting member 323 can be set in a cylindrical shape or the like, and the contour line of the limiting member 323 contacts the inner wall surface of the conical hole 2311. In this state, it can be generally regarded that the limiting member 323 and the end of the conical hole 2311 achieve line contact.

[0087] In some embodiments, as Figure 5 shown, a through water hole 24 is provided on the side wall 22 and / or the end wall 23. It can be understood that in the embodiment of the present invention, the water hole 24 can be provided only on the side wall 22; or the water hole 24 can be provided only on the end wall 23; or the water hole 24 can be provided on both the side wall 22 and the end wall 23. Of course, multiple water holes 24 can be provided to increase the rate of fluid conduction in the cavity by increasing the number of water holes. The cross-sectional dimension of the water hole in the embodiment of the present invention is less than a set value, so that the water hole can conduct fluid and prevent the disinfection particles in the cavity from flowing out through the water hole.

[0088] It should be noted that the embodiment of the present invention does not limit the cross-sectional shape of the water hole 24. For example, the cross-section of the water hole 24 can be set as circular, elliptical, triangular, rectangular, square, etc. Of course, multiple different shapes of water holes 24 can be provided on the same accommodating body 2. The following describes an embodiment in which two different shapes of water holes 24 are provided on the accommodating body 2:

[0089] As Figure 5 shown, when water passing holes 24 are provided on both the side wall 22 and the end wall 23, the water passing holes include a first water passing hole 241 and a second water passing hole 242. A plurality of the first water passing holes 241 are spaced apart on the end wall 23, and the cross-section of the first water passing hole 241 is circular. A plurality of the second water passing holes 242 are spaced apart on the side wall 22, and the cross-section of the second water passing hole 242 is triangular.

[0090] An embodiment of the present invention further provides a household electrical appliance, as Figure 1 shown, the household electrical appliance includes a fluid passage 1 and the sterilization device according to any one of the above embodiments. The inlet 11 of the fluid passage 1 is close to the moving body 3, and the outlet 12 of the fluid passage 1 is close to the accommodating body 2.

[0091] It should be noted that the fluid passage 1 in the embodiment of the present invention includes but is not limited to the water inlet passage, the washing cavity in the laundry treatment device, and other flow channels that are communicated with the washing cavity and can allow liquid to enter the washing cavity. It can also be the flow channels in other household electrical appliances such as fruit and vegetable cleaners and dishwashers. The sterilization device can be arranged in any channel for fluid circulation in the household electrical appliance, as long as the moving body can move relative to the fluid passage 1 and the accommodating body 2 under the action of the fluid.

[0092] Among them, the fluid passage 1 does not always have fluid passing through, but there are cases where fluid passes through and cases where fluid does not pass through. Then the sterilization device located in the fluid passage is not always immersed in the fluid. And when the fluid flows through the fluid passage, the fluid has a certain flow velocity. The fluid can pass through the accommodating body 2 and impact the disinfection particles 4 in the cavity 21, so that the disinfection particles 4 release the disinfection substance. The fluid can also act on the surface of the moving body 3, so that the moving body 3 moves relative to the accommodating body 2 under the action of the fluid, and then drives the disinfection particles 4 in the cavity 21 to move and rub. Then the release speed of the disinfection substance is accelerated by the water flow movement. And the movement of the moving body is realized by the impact of the fluid in the fluid passage, so there is no need to soak the disinfection particles, which is beneficial to reducing the loss of the disinfection substance and thus reducing the cost.

[0093] The above is only a preferred embodiment of the present invention, and is not intended to limit the protection scope of the present invention.
