According to one embodiment of the present disclosure, a base station is provided. Wherein the base station can be used to dock an autonomous surface cleaning apparatus such as a sweeping robot.
The surface cleaning apparatus may include a generally circular or rectangular plus circular housing. As shown in fig. 1 and 2, the surface cleaning apparatus 10 can include a wet cleaning portion and a dry cleaning portion. Wherein the wet cleaning part and the dry cleaning part may be disposed at a bottom of the housing, and may be in contact with the cleaning surface to perform wet cleaning and dry cleaning of the cleaning surface.
The wet cleaning part may include a first rotating member 11 and a second rotating member 12, and a mopping member (not shown in the drawings) such as a mop cloth, etc. may be provided on the first rotating member 11 and the second rotating member 12, respectively. The first rotating member 11 and the second rotating member 12 are arranged in parallel and can rotate around the rotating shafts, respectively, so as to mop the cleaning surface while the first rotating member 11 and the second rotating member 12 are in contact with the cleaning surface. A cleaning liquid receiving portion may be provided inside the housing of the surface cleaning apparatus, and the cleaning liquid is supplied to the mop through the cleaning liquid supply port, so that the cleaning surface is wet-cleaned by the cleaning liquid adsorbed by the mop.
The dry type cleaning part may include a roller brush part 13 and an edge brush part 14, wherein the number of the edge brush part 14 may be one or two, and in case of providing one edge brush part, it may be provided at one side of the surface cleaning apparatus, and in case of providing two edge brush parts, it may be provided at both sides of the surface cleaning apparatus, respectively. In the process of cleaning the cleaning surface, the side brush part 14 may be rotated to collect the garbage such as debris near the rolling brush part 13, so that the garbage is rolled into a dust collecting part provided inside a housing of the surface cleaning apparatus by rotating the rolling brush part 13, wherein the dust collecting part may be in the form of a dust collecting box through which the garbage from the cleaning surface is collected and stored.
Preferably in the present disclosure, the wet cleaning portion may be disposed at a rear side of the dry cleaning portion with respect to a working traveling direction of the surface cleaning apparatus. This allows for dry-then-wet cleaning. Further, the wet cleaning part may be movable up and down with respect to the wet cleaning part. Thus, when wet cleaning is not performed, the wet cleaning portion can be lifted so as not to make contact with the cleaning surface. While wet cleaning is performed, the wet cleaning portion may be controlled to contact the cleaning surface and may also be provided with additional pressure so that the wet cleaning portion in contact with the cleaning surface may provide additional driving force or resistance to the surface cleaning apparatus. In certain cleaning scenarios where stubborn stains and the like need to be cleaned, the pressure provided can cause the mop of the wet cleaning portion to more closely contact the cleaning surface, which can result in better cleaning. Further, although in the present disclosure the wet cleaning section is in the form of two rotating members, it will be appreciated that it may be provided as one rotating member, for example the rotating member may be a tracked rotating member, and the tracked rotating member may be arranged to rotate in or against the direction of travel of the surface cleaning apparatus to effect wet cleaning of the cleaning surface.
Fig. 3 shows a base station 20 according to an embodiment of the present disclosure. Wherein the base station can interface with the surface cleaning apparatus. After the surface cleaning device is parked at the base station, dust, debris and other garbage collected in the dust collecting part of the surface cleaning device is sucked to the base station so as to realize the emptying of the dust collecting part of the surface cleaning device, and/or the charging of the surface cleaning device, and/or the cleaning of the mopping piece of the surface cleaning device, and/or the supplementing of the cleaning liquid accommodating part of the surface cleaning device with cleaning liquid.
As shown in fig. 3, the base station 20 may include a base assembly 100, a first maintenance assembly 200, and a second maintenance assembly 300.
The base assembly 100 can provide a receiving space for receiving the surface cleaning apparatus, when a part of the surface cleaning apparatus enters the base assembly 100, the surface cleaning apparatus can be charged through the charging interface 120 provided in the base assembly 100, and/or dust, debris and other garbage collected in the dust collecting part can be sucked to the first maintenance assembly 200 through the suction interface 130 provided in the base assembly 100, and/or cleaning liquid can be replenished to the cleaning liquid receiving part of the surface cleaning apparatus through the liquid replenishing interface 140 provided in the base assembly 100; and/or the mop of the surface cleaning apparatus may be cleaned by a cleaning portion provided in the base assembly 100.
The primary function of the first maintenance assembly 200 is to suck up dust, debris and other debris collected in the dust collection portion of the surface cleaning apparatus and to store the sucked up debris. The second maintenance assembly 300 may include a cleaning liquid storage portion and a recovery liquid storage portion, and may be connected by a conduit, and the cleaning liquid stored in the cleaning liquid storage portion is provided to the fluid replacement port of the base assembly 100, and the cleaning liquid is provided to the surface cleaning apparatus, and the recovery liquid after self-cleaning the mop of the surface cleaning apparatus is pumped from the washing portion of the base assembly 100 to the recovery liquid storage portion through the conduit.
In the present disclosure, the first and second maintenance assemblies 200 and 300 may be selectively used in cooperation with the base assembly 100, so that base stations having different maintenance modes may be constructed. As shown in fig. 4, the self-emptying mode of the different maintenance modes may be achieved by mating the first maintenance assembly 200 with the base assembly 100. When the first maintenance assembly 200 is combined with the base assembly 100, the dust suction function of the dust collecting part of the surface cleaning apparatus can be realized, so that the dust of the dust collecting part of the surface cleaning apparatus can be emptied to the first maintenance assembly 200, and thus the self-emptying function of the surface cleaning apparatus can be realized. As shown in FIG. 5, the second maintenance assembly 300 may be engaged with the base assembly 100 to implement a self-cleaning mode and/or a cleaning liquid replenishment mode of different maintenance modes. In combination with the base assembly 100, the second maintenance assembly 300 may enable self-cleaning of the mop of the surface cleaning apparatus and/or may enable replenishment of the cleaning liquid receptacle of the surface cleaning apparatus with cleaning liquid. In addition, as shown in fig. 3, the first maintenance assembly 200 and the second maintenance assembly 300 may be used in cooperation with the base assembly 100 to implement a self-emptying mode, a self-cleaning mode, and/or a liquid replenishing mode among different maintenance modes. Specifically, debris from the dirt collection portion of the surface cleaning apparatus can be drawn through the first maintenance assembly 200 to empty the dirt collection portion of the surface cleaning apparatus, and cleaning liquid can be replenished to the cleaning liquid receptacle of the surface cleaning apparatus and/or provided to clean the mop of the surface cleaning apparatus through the second maintenance assembly 300. In addition, the base assembly 100 may be used alone to effect charging of the surface cleaning apparatus, it being noted that even after the base assembly 100 is combined with the first maintenance assembly 200 and/or the second maintenance assembly 300, the charging mode may be selected simultaneously after the respective mode of the first maintenance assembly 200 and/or the second maintenance assembly 300 is selected. While the role of the first and second maintenance assemblies 200, 300 is expressly defined in this disclosure, this is by way of example only, and it will be understood by those skilled in the art that maintenance assemblies having other functions may be selected for use with the base assembly or with a single function maintenance assembly or with a functionally integrated maintenance assembly, etc.
According to the combinable base station of the present disclosure, a user may select different components as desired to mate with a corresponding surface cleaning apparatus, such as the first maintenance assembly 200 and/or the second maintenance assembly 300 removably attached to the base assembly 100. For example, for a surface cleaning apparatus that performs only dry cleaning, the base assembly 100 can be selected to charge the surface cleaning apparatus, and if it is desired to empty the dust collecting portion of the surface cleaning apparatus, the first maintenance assembly 200 can be selected and engaged with the base assembly 100 to empty the dust collecting portion of the surface cleaning apparatus, such that a self-emptying mode and/or a charging mode can be performed. For example, in the case where there is no need to empty the dust collecting part of the surface cleaning apparatus, only the second maintenance assembly 300 and the base assembly 100 may be selected, and only the self-cleaning mode, the liquid replenishment mode, and/or the charging mode may be performed. In addition, according to the combinable base station of the present disclosure, if a certain component is updated at a later stage, a user can easily replace the previous component to use the updated component. The base station of the existing surface cleaning device is generally single in function, but for the multifunctional base station, the size is large, the use cost of a user is high, and the base station cannot be switched according to the user requirement. Therefore, the combinable base station according to the present disclosure can solve the problems existing in the existing base station and allow the user to accept or reject certain functions through the selection of hardware.
According to an alternative embodiment of the sectional base station of the present disclosure, the base assembly 100 may be designed to be disposed at a lower portion, the first maintenance assembly 200 may be designed to be disposed at a middle portion, and the second maintenance assembly 300 may be designed to be disposed at an upper portion. But the setting position may be changed according to the actual situation. Further, the first maintenance assembly 200 and the second maintenance assembly 300 are respectively provided with a combination portion combined with the base assembly 100. In addition, other functional components can be arranged to realize other working modes according to actual needs.
Further, although an external view using the first maintenance assembly 200 and the second maintenance assembly 300 is illustrated in fig. 4 and 5, that is, they may be accommodated in different housings. In the present disclosure, however, the first maintenance assembly 200 and the second maintenance assembly 300 may share a single assembly housing. The first maintenance assembly 200 and the second maintenance assembly 300 are both mounted into the assembly housing. Thus, when the user only needs the first maintenance assembly 200, the first maintenance assembly 200 can be assembled in the assembly housing, and when only the second maintenance assembly 300 is needed, the second maintenance assembly 300 can be assembled in the assembly housing, and when the first maintenance assembly 200 and the second maintenance assembly 300 are needed, the first maintenance assembly 200 and the second maintenance assembly 300 can be assembled in the assembly housing. By the mode, the product can be assembled before being delivered to a user, so that the problem of the user in the assembling process is avoided, and the user can select different functions according to the requirement of the user.
To allow the maintenance assembly to be reliably disposed on the base assembly 100, mounting structures may be provided on the functional assembly that interfaces with the base assembly 100. For example, if the first maintenance assembly 200 and the second maintenance assembly 300 are provided with separate housings, the first maintenance assembly 200 or the second maintenance assembly 300 may be provided with a mounting structure. When the first maintenance assembly 200 and the second maintenance assembly 300 share an assembly housing, then a mounting structure may be provided on the assembly housing. As one example, the mounting structure may include an insert and a latch, and the insert may be disposed at the maintenance assembly and the latch may be disposed at the base assembly. As shown in fig. 7, an insertion opening 611 may be provided in the base member 100, and the insertion opening 611 may be inserted by an insertion member provided in the maintenance member. And the insert may be locked by the locking members 612 after insertion. In an alternative embodiment, an insert may be provided in the base assembly and an insert port in the maintenance assembly, and a latch may be provided on either the base assembly or the maintenance assembly. In addition, the base assembly and the maintenance assembly are locked, so that a user can conveniently carry the base station. Also, in the case where the first maintenance assembly 200 and the second maintenance assembly 300 share the assembly housing, the volume of the base can be effectively reduced.

Wherein the base housing may include a first housing 111 (a rear housing shown in fig. 6), a second housing 112 (a left housing shown in fig. 6), and a third housing 113 (a right housing shown in fig. 6). The first, second and third housings 111, 112, 113 form a semi-enclosed space into which at least a portion of the surface cleaning apparatus enters when the surface cleaning apparatus is docked to the base assembly 100, wherein at least a portion of the rear side of the surface cleaning apparatus on which the mopping element is provided enters the semi-enclosed space, and may be integrally formed. Further, the base assembly 100 may also include a fourth housing 114 (the lower housing shown in fig. 7). The fourth housing 114 may include a support portion 115 and a ramp portion 116. The support portion 115 may be used to support at least a portion of the rear side of the surface cleaning apparatus. The ramp portion 116 may provide a passage that allows the surface cleaning apparatus to enter the semi-enclosed space.
The base assembly 100 may include a charging interface 120. When the surface cleaning apparatus is docked in place in the base assembly 100, the charging interface provided at the surface cleaning apparatus may be in contact with the charging interface 120 of the base assembly 100 and the surface cleaning apparatus is charged through the charging interface 120 connected to a power supply such as an external power supply. Wherein the charging interface 120 is elastically telescopic for better intimate abutment with the charging interface of the surface cleaning apparatus. Charging connector 120 may be disposed on an inner side of first housing 111, second housing 112, or third housing 113, where charging connector 120 is shown disposed on the inner side of first housing 111. And the charging interface 120 is arranged at a predetermined height position above the support portion 115, it is possible to avoid that the liquid affects the charging when washing the mop of the surface cleaning apparatus.
According to an alternative embodiment of the present disclosure, the base assembly 100 may include a suction port 130, and the suction port 130 may be interfaced with a suction port 15 (shown in fig. 1) of a surface cleaning apparatus, such that it may be in communication with a dirt collection portion of the surface cleaning apparatus, such that, in a self-emptying mode using the first maintenance assembly 200, debris from an integrated portion of the surface cleaning apparatus is drawn into the first maintenance assembly 200 via the interface 131 via the interfaced suction port 130 and suction port 15. The outside of the suction interface 130 may be provided with a suction seal, wherein the suction seal may surround the outside of the suction interface 130 and may be made of an elastic material to form a seal of the gas passage when the suction port 15 abuts the suction interface 130 to form a pneumatic engagement when the surface cleaning apparatus is parked in place with the base assembly 100. Alternatively, the suction port 130 may be provided on an inner side of the base assembly 100, for example, may be provided on an inner side of the first casing 111, or the second casing 112, or the third casing 113. Fig. 6 and 7 show that the suction connection 130 is arranged on the inner side of the third housing 113.
Optionally, the base assembly 100 may include a fluid replacement interface 140, wherein the fluid replacement interface 140 may be disposed on an inner side of the base assembly 100 and made of a flexible material, and the fluid replacement interface 140 may be bent when subjected to a certain pressure. This may be provided, for example, on the inner side of the first casing 111, the second casing 112, or the third casing 113. Fig. 6 and 7 show that the suction connection 130 is arranged on the inner side of the first housing 111. The fluid replacement interface 140 may extend outwardly from a surface of the inner side of the base assembly 100 by a predetermined length, and the fluid replacement interface 140 may be extended and retracted to be inserted into a fluid replacement port provided on the surface cleaning apparatus when the base assembly 100 is parked by the surface cleaning apparatus made of an elastic material. Because fluid replacement interface 140 is flexible, fluid replacement interface 140 can bend during insertion to prevent damage to the surface cleaning apparatus when fluid replacement interface 140 is misaligned with the fluid replacement port of the surface cleaning apparatus, and because fluid replacement interface 140 can bend, fluid replacement interface 140 can be guaranteed to be well inserted into the fluid replacement port of the surface cleaning apparatus during extension and retraction. The fluid replenishment interface 140 may be in fluid communication with the second maintenance assembly 300 via a conduit to provide cleaning fluid from the second maintenance assembly 300 to the surface cleaning apparatus for purposes of cleaning fluid replenishment. In the present disclosure, it is preferable that the fluid replacement interface 140 and the suction interface 130 are respectively disposed at both sides of the charging interface 120.
In the present disclosure, the charging mode and the other maintenance modes may be performed simultaneously, that is, the charging mode is performed while the other maintenance modes are performed. The charging mode may be initiated, for example, while performing a self-emptying mode, a self-cleaning mode, and/or a liquid replenishment mode.
Optionally, the base assembly 100 may include guide wheels 150. When the surface cleaning apparatus enters the base assembly 100, the guide wheels 150 can contact the sides of the surface cleaning apparatus and guide the surface cleaning apparatus into the receiving space in which the surface cleaning apparatus is received. In the present disclosure, the number of the guide wheels 150 may be two, and the two guide wheels 150 are respectively disposed at inner side surfaces of the second and third housings 112 and 113. The guide wheels 150 may be positioned at positions outside the inner side surfaces of the second and third housings 112 and 113 so that when the surface cleaning apparatus enters the accommodating space, the surface cleaning apparatus first contacts the guide wheels 150, and the surface cleaning apparatus is parked in place in the accommodating space by the guide of the guide wheels 150.
The supporting portion 115 of the base assembly 100 may be provided with a washing portion.

Fig. 14-16 show schematic views of a mixing bin 370 according to one embodiment of the present disclosure. As shown, the mixing cartridge 370 may include a first impeller portion 371, a second impeller portion 372, and a drive shaft 373. The first impeller portion 371, the second impeller portion 372, and the drive shaft 373 are housed in a housing of the mixing chamber 370. As shown in fig. 13, the mixing tank 370 may receive the detergent and cleaning liquid from the three-way valve through pipes. The mixed liquid in the mixing tank 370 may be provided to the base assembly 100 and/or the surface cleaning apparatus via a third conduit 431. For example, an inlet interface 375 and an outlet interface 376 may be provided on the housing of the mixing section 370, wherein the inlet interface 375 may receive the detergent and the cleaning liquid and the outlet interface 376 may provide the mixed liquid to the third conduit. It will be appreciated by those skilled in the art that instead of a three-way valve as described above, the mixing section 370 may be provided with separate inlets for receiving detergent and cleaning liquid, respectively.
In the present disclosure, the inlet interface 375 may be disposed corresponding to the first impeller portion 371. As shown in fig. 15 (showing the internal structure), the first impeller portion 371 may include a plurality of first blades, wherein the surface of the first blade may be configured as an arc surface to receive the impact force and/or the gravity of the liquid entering the inlet interface 375, so that the first impeller portion 371 may be rotated by the liquid from the inlet interface 375. The first impeller portion 371 may be fixedly secured to the shaft 373, and the second impeller portion 372 may also be fixedly secured to the shaft 373. When the first impeller portion 371 rotates, the transmission shaft 373 will be driven to rotate, so that the second impeller portion 372 also rotates. In the present disclosure, the first impeller portion 371 may be regarded as a rotation driving portion, and the second impeller portion 372 may be regarded as a rotation driven portion. The cleaning liquid such as cleaning water and the like and the cleaning agent such as detergent and the like entering the mixing chamber 370 are mixed by the rotation of the second impeller portion 372, and thus, the second impeller portion 372 serves as a stirring means. The mixed liquid may be supplied to the outside through a third pipe 431 provided near the bottom of the mixing bin 370 after sufficient mixing.
The driving shaft 373 may be supported on the top surface of the mixing chamber 370 by the first bearing 3731 and supported on the bottom surface of the mixing chamber 370 by the second bearing 3732, which may effectively reduce the rotational resistance and avoid the generation of noise. The first and second impeller portions 371, 372 may be fixed to the transmission shaft 373 by axial and radial fastening means, respectively. As an example, the first impeller portion 371 may be secured to the drive shaft 373 by a first axial snap spring 3733 and a first radial snap groove 3734, and the second impeller portion 372 may be secured to the drive shaft 373 by a second axial snap spring 3735 and a second radial snap groove 3736. By the fixing mode, the problem that the first impeller portion 371 and the second impeller portion 372 jump in the radial direction and the axial direction in the working process can be effectively prevented. Of course, it will be appreciated by those skilled in the art that other forms of securing may be used. According to the internal arrangement mode of the mixing bin disclosed by the invention, various advantages such as compactness, low noise, low cost and the like can be realized.
In the present disclosure, the direction of impingement of the fluid F entering the mixing bin 370 from the inlet interface 375 may be radial to the blades, see, for example, fig. 16 and 17. Alternatively, the force receiving point of each blade of the first impeller portion 371 may be located at the middle position of the blade, so that the first impeller portion 371 can be rotated well by the fluid impact, and the impact direction of the fluid may be substantially the radial direction of the blade. Each of the blades of the first impeller portion 371 is formed in an arc surface, and an axial included angle of the arc-shaped blade may range from 5 ° to 85 °. For example, from the lower portion of the arc-shaped blade to the upper portion of the arc-shaped blade (the up and down as used herein means the up and down in the state where the arc-shaped blade is in the operating state), the angle of the arc-shaped blade is gradually decreased with respect to the axial direction of the drive shaft. Thus, the arc-shaped blades have a predetermined inclination angle with respect to a direction perpendicular to the axial direction of the drive shaft. And each blade of the first impeller portion 371 is inclined in the rotation direction from the lower portion of the blade to the upper portion of the blade.
In the present disclosure, rather than providing the inlet interface 375 at the upper sidewall of the mixing silo 370, the inlet interface 375 may also be provided at the top of the mixing silo 370 and the incoming fluid may be directed at the blades, such as by the kinetic and potential energy of the fluid causing the first impeller portion 371 to rotate, as described above.
Each blade of the second impeller portion 372 is an arc surface, and the axial included angle range of the arc-shaped blade may be 5 ° to 85 °. For example, from the upper portion of the arc-shaped blade to the lower portion of the arc-shaped blade (the up and down as referred to herein means the up and down in the state where the arc-shaped blade is in the operating state), the angle of the arc-shaped blade is gradually decreased with respect to the axial direction of the drive shaft. Thus, the arc-shaped blades have a predetermined inclination angle with respect to a direction perpendicular to the axial direction of the drive shaft 373. And each blade of the second impeller portion 372 is inclined against the rotation direction from the upper portion of the blade to the lower portion of the blade, so that the cleaning agent and the cleaning liquid can be more sufficiently agitated by the second impeller portion 372 as the agitating means.
According to the mixing bin 370 disclosed by the invention, under the condition of a certain space, the kinetic energy and potential energy of the entering cleaning liquid can be fully utilized to complete the stirring and mixing of the mixed liquid, so that various advantages of low noise, low cost and the like are realized. Therefore, in the mixing bin disclosed by the invention, a good stirring effect can be realized under the condition that a motor and a speed reducing device are not used.

Wherein the liquid level detection device 374 may be used to detect a lower liquid level threshold and an upper liquid level threshold in the mixing bin 370. The level detection device 374 may be formed by one detector or more than two detectors to detect the lower level threshold and the upper level threshold. Here, three liquid level detection means are shown, wherein a first liquid level detection means may be used for detection of a lower liquid level threshold, a second liquid level detection means may be used for detection of a higher liquid level threshold, and a third liquid level detection means may be used in cooperation with the first liquid level detection means and the second liquid level detection means, respectively, for verification, etc.

As shown in fig. 20, the outlet end 3401 may further include a first guide channel 3403 and a retaining groove 3404. Wherein the first guide channel 3403 is used to connect the notch 3402 and the retaining groove 3404 so that, in the case where the detergent supply device 340 is pressed, the entering protrusion 3421 from the notch 3402 will slide into the retaining groove 3404 along the first guide channel 3403, for example, can slide into the retaining groove 3404 along the guide wall of the first guide channel 3403. Wherein the height of the limiting groove 3404 is higher than the height of the gap 3402, and the first guide channel 3403 extends upward from the gap 3402 to the limiting groove 3404, which may be arc-shaped and may include two sidewalls to form a channel. The first sidewall 3403a may have an end located above the notch 3402 (spaced apart from the notch 3402 by a certain distance, and one end of the first sidewall 3403a may be deviated at a central position of the notch 3402, for example, in a direction away from the stopper groove 3404) as a starting point, and an end point provided to the stopper groove 3404. The second side wall 3403b starts at the notch 3402, and a terminal point may be disposed below the limiting groove 3404 (spaced apart from the limiting groove 3404). The third sidewall 3404a of the groove corresponding to the first sidewall 3403a may be disposed to be straight (perpendicular to a horizontal plane on which the boundary of the notch is located) so as to define the position of the protrusion 3421. It should be noted that the reset lock 3420 is rotated since the detergent supply device 340 is stationary during the process of sliding the protrusion 3421 into the retaining groove 3404.
The outlet end 3401 may further include a second guide passage 3405, the second guide passage 3405 including a fourth side wall 3405a, a fifth side wall 3405b, and a sixth side wall 3405c, and being substantially V-shaped. And a locking groove 3405d is provided between the fourth side wall 3405a and the fifth side wall 3405 b.

When the user's pressing is completed, the protrusion 3421 enters the second guide channel 3405 due to the rotation of the reset lock 3420 and the elastic force of the reset spring 3430, and the protrusion 3421 enters the non-limiting groove 3406 along with the rotation of the reset lock 3420 by the guide function of the side wall of the second guide channel. At this time, the detergent supply device 340 is lifted upward by a predetermined height.
Thereafter, the user may take out the detergent supply device 340. During the removal process, the protrusion 3421 can slide along the third guiding path 3407 until the protrusion 3421 moves to the next notch, so that the detergent supply device 340 can be disengaged from the reset lock 3420. The third guide passage 3407 may include a seventh side wall 3407a and an eighth side wall 3407b, wherein one end of the seventh side wall 3407a may be joined with the other end of the fifth side wall 3405b, and the other end of the seventh side wall 3407a may extend to the next gap. One end of the eighth sidewall 3407b may be connected with the non-limiting groove 3406, and the other end may be connected with the first sidewall of the next self-locking resilient structure.
In the above embodiments, one of the self-locking rebound structures is described, which can be arranged circumferentially around the outlet end 3401 so that the protrusions 3421 can pass from one structure to another, so that the self-locking rebound operation can be repeated. In the present disclosure, four structures may be provided around the circumference of the outlet end 3401 such that when the reset lockout 3420 is rotated 90 °, it is switched from one structure to another, thereby allowing a self-locking rebound operation to be performed again. However, the number of the structures may be other, for example, six structures, and in the case of six structures, the reset lock 3420 rotates by 60 ℃ each time to perform the next self-locking rebound operation. In addition, in the case of four structures, four protrusions 3421 are correspondingly disposed on the reset lock 3420, and in the case of six structures, six protrusions 3421 are correspondingly disposed on the reset lock 3420, and the number of the protrusions may be correspondingly set. Wherein, this structure can be provided with N to the bellying also can set up to N, also can set up to other quantity, in the switching process of locking state and non-locking state each time, reset hasp 3420 can rotate 360 °/N angle at every turn.
During the rotation of the reset lock 3420, since there is an elastic force of the reset spring 3430, when the user releases the detergent supply device 340 after pressing the detergent supply device 340, the reset lock 3420 is subjected to an upward elastic force due to the elastic force of the reset spring 3430 and is lifted up (e.g., may be applied to the reset lock 3420 by the liftout member 3440), so that after the protrusion 3421 is disengaged from the latching groove, the protrusion 3421 enters the third guide path due to the elastic force of the reset spring 3430, and the protrusion 3421 enters the non-limiting groove 3406 as the reset lock 3420 rotates.
Furthermore, an ejection spring 3450 and an ejector 3460 may be further provided, wherein the ejection spring 3450 cooperates with the ejector 3460 for ejecting at least a portion of the detergent supply device 340 to the outside of the housing. Wherein the jacking members 3460 may contact the bottom surface of the detergent supplying device 340 and may pass through the housing 3410.
According to one example of the present disclosure, the reset lockout 3420 may be a ring-like structure, such as shown in fig. 20, and the protrusions 3421 may be located on an inner circumferential surface of the reset lockout 3420. And a stopping structure 3422 may be further disposed on the reset lock 3420. The latching structure 3422 may correspond to the latching recess 3412 provided in the housing 3410. As an example, a latching recess 3412 corresponding to the latching structure 3422 may be provided on the bottom outer surface of the housing 3410. As shown in fig. 20, the latching structure 3422 may be provided on the outer circumferential surface of the reset shackle 3420, and may be an arm portion extending from the outer circumferential surface, and a latching protrusion may be provided at an end of the arm portion. For example, the latching projection may slide into the latching recess 3412 at least when the detergent supply device 340 is in a locked state, so as to restrict the rotation of the reset lock 3420.
Although the above-described resilient latch structure is described in the present disclosure in connection with a base station, it should be understood by those skilled in the art that the resilient latch structure may be used in other aspects and is not limited to the base station described in the present disclosure.
According to the technical solution of the present disclosure, the cleaning agent supply device 340 is provided separately from the cleaning liquid storage part 350 and the recovery liquid storage part 360 and is provided at the rear side of the position where the cleaning liquid storage part 350 and the recovery liquid storage part 360 are adjacent. The user can lock by simply pressing the detergent supply device 340 and unlock by pressing again. This eliminates the need for a release button or the like.
Generally, the detergent supply device 340 may be replaced to be inserted into the second maintenance assembly 300, but there may occur a leakage or the like in the detergent supply device 340. In the following description, although the detergent supply device is exemplified, it should be noted that the corresponding leakage preventing structure of the detergent supply device 340 described below can also be applied to other liquid containers.
In the present disclosure, a two-stage valve structure may be provided inside the outlet end 3401 of the detergent supply device 340. The two-stage valve structure may be disposed upstream and downstream of the fluid. The first stage may be a one-way valve and may be disposed upstream of the fluid. And the second stage valve member may be a two-way valve, a one-way valve, and may be disposed downstream of the fluid. Thus, the leakage condition can be effectively prevented through the two-stage sealing structure. The upstream and downstream described herein are for upstream and downstream when the liquid flows out from the container (the detergent supply device 340).
A suitable valve configuration may be selected in the present disclosure to prevent leakage from occurring. As one example, the first stage valve structure may be a first stage check valve and the second stage valve structure may be a second stage valve member, which may be in the form of a second stage check valve, a ball valve, or the like, as examples. The first stage of the first stage check valve allows a flow direction configured to: the liquid is allowed to flow through the first stage one-way valve in a first flow direction, the first flow direction is the direction from the upstream to the downstream of the outflow path of the liquid, the liquid is prevented from flowing through the first stage one-way valve in a second flow direction, and the second flow direction is the direction from the downstream to the upstream of the outflow path of the liquid. The second stage of the second stage valve member allows flow to be configured as: the liquid is allowed to flow through the second stage valve member in the first flow direction and/or the second flow direction. The first stage allowed flow direction and the second stage allowed flow direction referred to in this disclosure may be the designed flow direction of the valve itself. For example, the first stage allows flow in a direction that the first stage check valve allows fluid flow without external force being applied thereto, and the second stage allows flow in a direction that the second stage valve allows fluid flow without external force being applied thereto. In summary, in the present disclosure, the first stage allows the flow direction to be the first flow direction. The second stage allows the flow direction to be the first flow direction; or in a second flow direction; or a first flow direction and a second flow direction.
For example, in the case where the first stage check valve is a first duckbill valve, the first stage check valve may be designed to flow in an upstream to downstream direction, and in the case where the second stage valve member is a second duckbill valve, the other duckbill valve may be designed to flow in a downstream to upstream direction. Thus, two duckbill valves designed to flow in opposite directions can cooperate to prevent fluid leakage. When the liquid is allowed to flow out (external force is applied), the first duckbill valve can be opened through suction, the liquid flows out to the second duckbill valve according to the design flow direction of the first duckbill valve, and the second duckbill valve can be pushed open to form a flow path, so that the liquid can flow from the upstream to the downstream through the second duckbill valve.
Preferably in the present disclosure, the first stage one-way valve may be a duckbill valve, wherein the duckbill valve may be made of a soft material, such as soft gel. The second stage valve member may be a ball valve. The ball valve can include a sealing ball, which can be received in a support body, which can be received inside the outlet end 3401, and a support body.
Fig. 21 is an exploded schematic view of the detergent supply device 340, and fig. 22 is a sectional view of the detergent supply device 340. A first stage check valve 3471, for example in the form of a duckbill valve, may be disposed within the outlet end 3401 at an upstream location, for example adjacent the inlet of the outlet end 3401. And a second stage valve element in the form of a sealing ball may be provided at a downstream location, such as an outlet adjacent the outlet end 3401. The second-stage valve member 3472 may include a sealing ball 3473 and a support body 3474. The sealing ball 3473 may be made of glass or the like. The support body may be made of a flexible material. The sealing ball 3473 disposed inside the support body may move inside the support body 3474. The supporting body 3474 may be designed to have a notch in the present disclosure, for example, as shown in fig. 21, the supporting body 3474 can be opened and closed to allow the sealing ball 3473 to move. Furthermore, a blocking structure may be further disposed inside the supporting body 3474, and a function of one-way sealing may be achieved when the sealing ball 3473 abuts against the blocking structure 3476. The blocking structure may be arranged at a lower position of the support body. The support 3474 may be designed to limit the travel of the sealing ball 3473. For example, a stop 3477 may be provided, wherein the stop 3477 may be configured such that when the sealing ball is lifted, the sealing ball may move upstream. When the sealing ball is not jacked up, the limiting structure 3477 may apply a pressure to the sealing ball 3473 toward the downstream, so that the sealing ball 3473 abuts against the blocking structure, thereby achieving the sealing effect. Further, the spacing structure 3477 may not provide downstream pressure to the sealing ball 3473 in this disclosure. In the present disclosure, in order to allow the liquid to pass through the limiting structure 3477, a through hole may be opened on the limiting structure 3477 so as to allow the liquid to flow through when the limiting structure abuts against the sealing ball. Of course, it will be understood by those skilled in the art that the structure allowing the liquid to flow through may take other forms, such as providing notches, openings, teeth, etc. on the stopper 3477.
When the cleaning agent supply device 340 is mounted to the second maintenance assembly 300, the docking port provided to the second maintenance assembly 300 or a jacking structure provided at the docking port may jack the sealing ball 3473 such that the sealing ball 3473 moves upstream and the sealing ball 3473 disengages from the blocking structure, thereby allowing the liquid to drain. Furthermore, a pump device, such as a peristaltic pump, can be provided in the base station in order to draw liquid out of the cleaning agent supply 340. The sealing ball may also perform a sealing function to prevent residual liquid from flowing out when the detergent supply device 340 is taken out.
Generally, there is a risk of leakage when the detergent supply device 340 is inverted or squeezed. The solution of the present disclosure, through the two-stage sealing form, if liquid leaks from the first stage seal, the leakage risk will be greatly reduced due to the presence of the second stage seal. And after the sealing ball is placed in the base station, the sealing ball is jacked up, so that the liquid discharge is not influenced.
