The body 110 has a receiving cavity 120, a plurality of cleaning cylinders 10 are disposed in the receiving cavity 120, and each cleaning cylinder 10 has a cleaning cavity 11. The fluid intake assembly 30 is mounted to the body 110 and communicates with each of the cleaning chambers 11. The fluid inlet assembly 30 is used for selectively allowing the outside fluid to enter at least one cleaning chamber 11. The fluid extraction assembly 40 is mounted to the body 110 and communicates with each of the cleaning chambers 11.

Referring to fig. 1 and 2, in some embodiments, fluid intake assembly 30 includes an intake conduit 32, a plurality of delivery conduits 33, and an intake valve 34. The inlet pipe 32 is used for introducing fluid from the outside. Each flow line 33 communicates with one cleaning cartridge 10. An inlet valve 34 is connected to the inlet conduit 32 and the flow conduits 33 and is configured to selectively communicate the inlet conduit 32 with one or more of the plurality of flow conduits 33 and to regulate the flow of fluid into the flow conduits 33.

For example, the number of cleaning cartridges 10 is 4, the number of flow conduits 33 is 4, and 1 cleaning cartridge 10 is connected to each flow conduit 33. The inlet valve 34 may be selected to isolate the inlet conduit 32 from the 4 flow conduits 33 to prevent ambient fluid from entering the cleaning cartridge 10. The inlet valve 34 may also selectively communicate the inlet conduit 32 with 1, 2, 3, or 4 delivery conduits 33 to deliver fluid to the corresponding cleaning cartridge 10. In one embodiment, the flow of fluid into the flow conduit 33 may be adjusted by controlling the length of time that the inlet valve 34 opens the inlet conduit 32 into communication with the flow conduit 33. In another embodiment, the size of the cross section of the inlet conduit 32 in communication with the flow conduit 33 can also be controlled by controlling the inlet valve 34 to regulate the flow of fluid into the flow conduit 33.

Referring to fig. 1 and 2, in some embodiments, the cleaning apparatus 100 further includes a cover 130 for enclosing the receiving cavity 120.

In some embodiments, the cleaning apparatus 100 extracts fluid (e.g., gas) from the cleaning chamber 11 through the fluid extraction assembly 40, so as to form a negative pressure in the cleaning chamber 11, the external fluid can enter the cleaning chamber 11 under the action of the negative pressure, in the case that the object to be cleaned and the cleaning liquid are stored in the cleaning chamber 11, the fluid entering the cleaning chamber 11 from the outside impacts the cleaning liquid to generate an oscillating stripping stain, and a large amount of bubbles are generated along with the impact of the cleaning liquid, and the bubbles are broken when contacting the object to be cleaned to generate oscillation, so as to strip the stain on the object to be cleaned through oscillation. Thus, the cleaning device 100 does not rub the object to be cleaned when cleaning the object to be cleaned, and can prevent the object to be cleaned from being damaged by a large friction force.

In one embodiment, each cleaning cylinder 10 communicates with the fluid intake assembly 30 and the fluid extraction assembly 40, respectively, so that the cleaning object in each cleaning cylinder 10 can be cleaned by the impact of the cleaning liquid and the oscillating action of bubble collapse to accomplish cleaning without abrading the cleaning object.

In one embodiment, the inlet conduit 32 is disposed through the housing 110, i.e., the inlet conduit 32 is partially disposed inside the housing 110 and partially disposed outside the housing 110 to introduce the external fluid into the cleaning cylinder 10. The flow pipe 33 and the inlet valve 34 are housed inside the body 110, and the flow pipe 33 communicates with the inlet pipe 32 inside the body 110. In yet another embodiment, the inlet conduit 32 may be located completely outside the body 110, the fluid delivery conduit 33 and the inlet valve 34 still being housed inside the body 110, the body 110 being provided with a through hole for communicating the inlet valve 34 with the inlet conduit 32. The inflow duct 32 is disposed outside the machine body 110, so that the space in the machine body 110 can be saved, the overall size of the cleaning apparatus 100 can be reduced, and the cleaning apparatus 100 can be miniaturized.

Referring to fig. 1 and 2, in some embodiments, the fluid extraction assembly 40 includes an outlet conduit 41, a plurality of flow conduits 44, and an outlet valve 45. Wherein the outflow conduit 41 is used for leading out the fluid in the cleaning chamber 11. Each flow conduit 44 communicates with one cleaning cartridge 10. The outflow valve 45 connects the outflow conduit 44 and the outflow conduit 41, and is used to selectively communicate the outflow conduit 41 with one or more of the plurality of outflow conduits 44, and to regulate the flow of fluid into the outflow conduit 41.

For example, the number of cleaning cartridges 10 is 4, the number of flow conduits 44 is 4, and 1 cleaning cartridge 10 is connected to each flow conduit 44. The outflow valve 45 may be selected to exclude the outflow conduit 41 from the 4 flow conduits 44 to prevent fluid in the cleaning cartridge 10 from entering the outflow conduit 41. Outflow valve 45 may also selectively communicate inflow conduit 32 with 1, 2, 3, or 4 fluid delivery conduits 33 to discharge fluid from the corresponding cleaning cartridge 10. In one embodiment, the flow of fluid into the outlet flow conduit 41 may be regulated by controlling the length of time that the outlet valve 45 opens the outlet flow conduit 41 to the flow conduit 44. In another embodiment, the size of the cross section of the outflow conduit 41 communicating with the flow delivery conduit 44 can also be controlled by controlling the outflow valve 45 to regulate the flow of fluid into the outflow conduit 41.

Referring to fig. 1 and 2, in some embodiments, the fluid extraction assembly 40 may further include an extraction unit 42 disposed in the body 110, wherein the extraction unit 42 is communicated with an outlet of the outflow conduit 41 and is used for extracting the fluid in the outflow conduit 41. In one embodiment, the pumping unit 42 is a gas pump extending into the outlet flow pipe 41 to pump the fluid (e.g., gas) in the outlet flow pipe 41. When the outflow valve 45 communicates the outflow conduit 41 with the flow delivery conduit 44, the air pump can pump the air in the cleaning cartridge 10 corresponding to the flow delivery conduit 44 so that the inside of the cleaning cartridge 10 is in a negative pressure state.

Referring to fig. 1 and 2, in some embodiments, the fluid extraction assembly 40 further includes a power unit 43 disposed in the body 110. The power unit 43 is connected to the extraction unit 42 and is used to power the extraction unit 42. For example, the pumping unit 42 is an air pump, and the power unit 43 is a motor, and the motor is connected to the air pump for driving the air pump to pump air.

Referring to fig. 1 to 3, in some embodiments, the cleaning apparatus 100 may further include at least one impeller 20, and the impeller 20 is disposed in the cleaning cylinder 10 and is communicated with a fluid delivery pipe 33. For example, the cleaning apparatus 100 includes 4 cleaning cartridges 10, and the pulsator 20 is disposed in 1, 2, 3, or 4 of the cleaning cartridges 10. The external fluid enters the impeller 20 after sequentially passing through the inflow pipe 32, the inlet valve 34 and the flow transmission pipe 33, and is sucked into the cleaning cylinder 10 from the impeller 20 under the negative pressure, so that the impeller 20 is driven to rotate by the flow of the fluid sucked into the cleaning cylinder 10, thereby performing the cleaning operation on the object to be cleaned. Wherein the cleaning operation includes one or more of a washing operation, a dehydrating operation, and a drying operation.

In one embodiment, the pulsator 20 rotates to perform a washing operation. The cleaning cylinder 10 is internally provided with objects to be cleaned and cleaning liquid, the impeller 20 stirs the cleaning liquid to form turbulent flow, when the turbulent flow is contacted with the objects to be cleaned, a stable saturated layer cannot be formed on the surface of the objects to be cleaned, so that stains are easily dissolved in the liquid under the cleaning of the turbulent flow and are separated from the objects to be cleaned, the cleaning effect is enhanced, and the cleaning time is shortened.

In one embodiment, the pulsator 20 rotates to perform a dehydration operation. The cleaning cylinder 10 stores the object to be cleaned, and the impeller 20 rotates to drive the object to be cleaned to rotate, so that the object to be cleaned is dehydrated and the object to be cleaned is prevented from being entangled with each other.

In one embodiment, the pulsator 20 rotates to perform a drying operation. The cleaning cylinder 10 is filled with the object to be cleaned, the flow pipeline 33 conveys hot air to the impeller 20, the hot air enters the cleaning cylinder 10 through the impeller 20 under the action of negative pressure, and the impeller 20 rotates to drive the hot air flow to form vortex so as to dry each position of the object to be cleaned.

Referring to fig. 3 and 4, in some embodiments, the pulsator 20 includes a base plate 22 and blades 23 disposed on the base plate 22. The chassis 22 is provided with an inlet 221, and the inlet 221 is used for allowing external fluid to enter the interior of the chassis 22. The blades 23 are communicated with the inside of the chassis 22, the side 231 of the blades 23 is provided with an outlet 211, the outlet 211 is used for allowing the fluid entering the inside of the chassis 22 to flow out, and the fluid flowing out from the blades 23 can drive the impeller 20 to rotate under the condition that the fluid inside the chassis 22 is subjected to the suction force along the direction from the inlet 221 to the outlet 211.

Referring to fig. 4, in some embodiments, the blades 23 include a plurality of blades 23, and the plurality of blades 23 are configured to swirl to agitate the cleaning solution in the cleaning cartridge 10 as the blades 23 rotate. In the case that the cleaning cylinder 10 contains liquid, when the fluid enters the cleaning cylinder 10 through the pulsator 20 rotating at a high speed, the fluid impacts the liquid in the cleaning cylinder 10 to generate a large amount of air bubbles, and the air bubbles are broken when contacting the object to be cleaned to generate oscillation, so that the dirt on the object to be cleaned is peeled off by the oscillation. So, different from traditional motor drive impeller, impeller 20 of this application embodiment peels off the spot on treating the cleaning thing through forming bubble water and torrent, can strengthen clean effect, and avoids treating the cleaning thing and produce great friction, leads to treating the cleaning thing to damage.

Referring to FIG. 4, in some embodiments, the plurality of vanes 23 are evenly distributed around the center of the inlet 221. Therefore, the power balance of the blades 23 during rotation is facilitated, the rotation of the impeller 20 is stable, and the shaking or swinging degree of the impeller 20 during rotation is reduced.

Referring to fig. 4, in some embodiments, each blade 23 has an outlet 211, and the center of each outlet 211 is spaced the same distance from the center 2211 of the inlet 221. Wherein the center of each outlet 211 is the same distance from the center 2211 of the inlet 221, i.e., each outlet 211 is located on the circumference of the same concentric circle centered on the center 2211 of the inlet 221. During the process of being sucked into the cleaning cylinder 10 from the outlet 211, the fluid powers the rotation of the pulsator 20, and the center of each outlet 211 is at the same distance from the center 2211 of the inlet 221, so that the position of each outlet 211 provides the same torque for the rotation of the pulsator 20. Therefore, the power balance of the blades 23 during rotation is facilitated, the rotation of the impeller 20 is stable, and the shaking or swinging degree of the impeller 20 during rotation is reduced.

In some embodiments, a plurality of outlets 211 are provided on each blade 23 to increase the flow of fluid into the cleaning cylinder 10 and to increase the power provided by the fluid to rotate the pulsator 20. The outlet 211 of each blade 23 can be located on the same circumference of a circle with the center 2211 of the inlet 221 together with at least one outlet 211 of any other blade 23, so as to ensure that the torque provided by the fluid flowing out of the outlet 211 to the rotation of the pulsator 20 can be balanced among different blades 23, thereby ensuring the stable rotation of the pulsator 20.

In one embodiment, each outlet 211 on the same blade 23 is the same size to facilitate manufacturing. The adjacent outlets 211 on the same blade 23 are equally spaced to provide uniform power along the radial direction of the blade 23.

In yet another embodiment, the size of the opening gradually increases from one end near the center 2211 of the inlet 221 to the other end away from the center 2211 of the inlet 221 on the same vane 23. That is, the outlet 211 closer to the outer side (tip) of the blade 23 has a larger size, and the outlet 211 closer to the inner side (root) of the blade 23 has a smaller size. Thus, the outlet 211 at the outer side of the blade 23 provides a large moment for the rotation of the pulsator 20, and is the main power for driving the pulsator 20 to rotate; the fluid flowing out from the outlet 211 near the inner side of the blades 23 is mainly used for ensuring the stable rotation of the impeller 20, so that the blades 23 are stressed stably along the radial direction, and the shaking or swinging degree of the impeller 20 during rotation is reduced. The spacing between adjacent outlets 211 increases from one end near the center 2211 of the inlet 221 to the other end away from the center 2211 of the inlet 221. That is, the outlets 211 closer to the outer side of the blade 23 are distributed more densely, and the outlets 211 closer to the inner side of the blade 23 are distributed more sparsely. To provide a greater power at a position close to the outside of the blades 23 to increase the rotation speed of the pulsator 20.

In some embodiments, the shape of the outlet 211 may be circular, rectangular, triangular, etc., without limitation. In one embodiment, the outlet 211 is circular in shape to facilitate manufacturing and to improve the utilization of the area of the side of the blade 23.

In some embodiments, the number of the plurality of blades 23 is an odd number, as shown in fig. 4 and 5, for example, the number of the plurality of blades 23 is 3, 5, 7, etc., which are not listed here. The odd number of blades 23 can reduce resonance during rotation, and improve the dynamic balance of the rotation of the blades 23.

In some embodiments, the number of the plurality of blades 23 is even, and the shape of the plurality of blades 23 is not completely consistent, so as to reduce resonance during rotation and improve dynamic balance of rotation of the blades 23. For example, the number of blades 23 is 4, wherein the size of 1 blade 23 is different from the size of the other 3 blades 23. The equivalent center of gravity of the plurality of blades 23 is located at the center 2211 of the inlet 221 to ensure dynamic balance.

Referring to fig. 4, in some embodiments, the base plate 22 includes a first face 225, a second face 226, and a side face 227, the first face 225 and the second face 226 are opposite, the side face 227 of the base plate 22 connects the first face 225 and the second face 226, the inlet 221 is opened on the first face 225, and the vane 23 is opened on the second face 226. The blades 23 are disposed on the second face 226, so that the blades 23 can be disposed close to the inlet 221, and the moment arm corresponding to the moment at the outlet 211 is relatively short, so that the fluid provides a relatively large power to the pulsator 20.

In one embodiment, the blades 23 are located in the second face 226, the circumference of the chassis 22 is the outermost periphery of the entire pulsator 20, so that the size of the pulsator 20 in the horizontal direction is small, the outlet 211 is closer to the rotation center of the pulsator 20, i.e., the center 2211 of the inlet 221, so as to shorten the force arm corresponding to the moment at the outlet 211 to make the fluid provide more power for the pulsator 20. In another embodiment, the vane 23 may partially extend beyond the second face 226, i.e., the end of the vane 23 distal from the center 2211 of the inlet 221 is a distance from the center 2211 of the inlet 221 that is greater than the radius of the second face 226. Therefore, the vortex range generated by the rotation of the fluid in the cleaning cylinder 10 driven by the blades 23 is wider, and the cleaning range is wider.

Referring to fig. 4, in some embodiments, the distance between the highest point of the top of the blade 23 and the second surface 226 is [2.0cm,4.0cm ], so that the blade 23 is close to the second surface 226, and the blade 23 is not easily contacted with the object to be cleaned during the rotation of the pulsator 20, thereby preventing the object to be cleaned from being damaged by the friction between the pulsator 20 and the object to be cleaned.

Referring to FIG. 4, in some embodiments, the side 231 of the vane 23 extends from the second face 226 to extend the range of rotation of the fluid carried by the vane 23 to generate a greater range of swirl. The blade 23 further includes a connection surface 233, the connection surface 233 is used for obliquely connecting the second surface 226 and the side surface 231 of the blade 23, and the connection surface 233 is a streamline arc surface to reduce flow resistance, so that the rotation of the pulsator 20 is smoother, and turbulent flow is easier to produce.

Referring to fig. 5, in some embodiments, the blades 23 extend from the side 227 of the impeller 20 to expand the range of rotation of the fluid driven by the blades 23 and generate a greater range of swirl.

Referring to fig. 4, in some embodiments, a plurality of guiding members 25 are disposed in the chassis 22, each guiding member 25 corresponds to one blade 23, each guiding member 25 and the corresponding blade 23 define a flow channel 21, one end of each flow channel 21 is communicated with the inlet 221, and the other end of each flow channel 21 is provided with an outlet 211 opened on the blade 23. Fluid enters the flow channel 21 from the inlet 221 and enters the cleaning cylinder 10 from the outlet 211 under the action of the negative pressure in the cleaning cylinder 10.

In some embodiments, the shape of the guide 25 corresponds to the shape of the blade 23, and the plurality of guides 25 are overall in a spiral shape to form the spiral flow channel 21 in cooperation with the blade 23, so as to guide the fluid in the impeller 20, and make the fluid entering the cleaning cylinder 10 from the impeller 20 more easily form a vortex to create turbulence.

Referring to fig. 6, in some embodiments, each flow channel 21 is divided into a first sub-flow channel 214 and a second sub-flow channel 215 which are isolated from each other, and outlets 211 are disposed on two opposite sides of the vane 23. The pulsator 20 further includes a valve 27 disposed in the chassis 22 and corresponding to the flow passage 21, the valve 27 being configured to selectively communicate the first sub-flow passage 214 with the inlet 221 so that the fluid flowing out of the outlet 211 of one side of the blades 23 can drive the pulsator 20 to rotate in the forward direction, and communicate the second sub-flow passage 215 with the inlet 221 so that the fluid flowing out of the outlet 211 of the other side of the blades 23 can drive the pulsator 20 to rotate in the reverse direction.

For example, in the embodiment illustrated in fig. 6, the vane 23 includes first and second opposing sides 2314 and 2315, the first side 2314 is provided with a first outlet 2114, the second side 2315 is provided with a second outlet 2115, the first sub-flow passage 214 communicates the first outlet 2114 with the inlet 221, and the second sub-flow passage 215 communicates the second outlet 2115 with the inlet 221. The clockwise rotation of the pulsator 20 is a forward rotation, and the counterclockwise rotation is a reverse rotation. When the valve 27 is deflected to the right (in the opposite direction as shown in fig. 6), the fluid in the second sub-flow passage 215 can be blocked from entering the cleaning cartridge 10 from the second outlet 2115, and at the same time, the path of the fluid flowing out of the first sub-flow passage 214 from the first outlet 2114 is opened, so that the fluid in the pulsator 20 enters the cleaning cartridge 10 from the first outlet 2114, and the fluid at the first outlet 2114 is "sucked" into the cleaning cartridge 10 under the action of the negative pressure, so as to drive the pulsator 20 to rotate forward. When the valve 27 is deflected to the left (as shown in fig. 6), the fluid in the first sub-flow passage 214 can be blocked from entering the cleaning cartridge 10 from the first outlet 2114, and the fluid in the pulsator 20 can enter the cleaning cartridge 10 from the second outlet 2115 by opening the path of the fluid flowing out of the second sub-flow passage 215 and the second outlet 2115. The fluid at the second outlet 2115 is "sucked" into the cleaning cylinder 10 under the negative pressure, driving the pulsator 20 to rotate in reverse.

In other embodiments, the clockwise rotation direction of the pulsator 20 may be a forward rotation direction, and the counterclockwise rotation direction may be a reverse rotation direction, which is not limited herein.
