Description

Wet surface cleaning system

Technical Field

The present disclosure relates to a wet surface cleaning system, and more particularly to a multi-purpose wet surface cleaning system having a portable subassembly removably mounted on a support assembly.

Background

Wet surface cleaning apparatuses, which are usually vacuum + water cleaning wet surface cleaning apparatuses, are usually of the upright type. Upright wet surface cleaning apparatuses typically include a cleaning base on which a main body is pivotally mounted. The various components of the main body of the wet surface cleaning apparatus, i.e. the vacuum motor, supply tank, recovery tank, rechargeable battery, etc. may be mounted on the main body, which is pivotally mounted on a cleaning base, which is moved back and forth across the floor surface to cause cleaning to be completed.

In recent years, there has been a multi-purpose wet surface cleaning apparatus which combines the wet surface cleaning apparatus with a portable vacuum cleaner in a vertical orientation. Such a multi-purpose wet surface cleaning apparatus may be used as a wet surface cleaning apparatus for wet cleaning of a floor surface, and may also be used to clean surfaces above a floor surface to be cleaned, such as table tops, counter tops, curtains and the like, using a detachable portable vacuum cleaner. A multi-purpose wet surface cleaning apparatus comprises a wet surface cleaning apparatus assembly and a dry vacuum cleaner assembly. The wet surface cleaning apparatus assembly and the dry vacuum cleaner assembly, which together form a typical upright wet surface cleaning apparatus, can be separated from each other, and the dry vacuum cleaner assembly, which includes a suction power source and a rechargeable battery, used with a dirt cup or other cleaning accessory, forms a stand-alone portable hand-held vacuum cleaner.

The multi-purpose wet surface cleaning apparatus, when in use, enables the hand-held vacuum cleaner to be used and operated independently of or at a substantial distance from the body of the wet surface cleaning apparatus. However, when the hand-held vacuum cleaner is used independently of the main body of the wet surface cleaning apparatus, the function of wet surface cleaning is lacking. More importantly, to maintain the versatile use of such wet surface cleaning functions, it is desirable to maximize its compact structure so that it is easier to use at a considerable distance from the main body of the wet surface cleaning apparatus.

Fig. 4 and 5 are schematic structural views of a cleaning base according to one embodiment of the present disclosure. Fig. 6 to 9 are schematic structural views of a cleaning base according to another embodiment of the present disclosure. Fig. 10 and 11 are schematic structural views of a cleaning base according to a third embodiment of the present disclosure.

As shown in fig. 4 and 5, the cleaning base 100 is used for cleaning a surface to be cleaned, and the cleaning base 100 may include a cleaning module 110, and the cleaning module 110 may be driven to rotate so as to clean the surface to be cleaned by frictional contact between the surface of the cleaning module 110 and the floor surface to be cleaned.

In one embodiment, as shown in fig. 10 and 11, the cleaning module 110 may be formed in the form of a roll brush, for example, the cleaning module 110 includes a first power part 111 and cleaning members 112; the cleaning member 112 is disposed outside the first power portion 111, for example, the cleaning member 112 wraps the first power portion 111 and can rotate together with the first power portion 111. The first power portion 111 can be driven to rotate by the cleaning driving device 115, so that the cleaning member 112 rotates, and the cleaning member 112 and the surface to be cleaned move relatively to each other, thereby cleaning the surface to be cleaned.

On the other hand, as shown in fig. 4 to 9, the cleaning module 110 may also be formed in a crawler-type structure, and specifically, the cleaning module 110 includes a first power part 111, a second power part 113, and a cleaning member 112, wherein the cleaning member 112 is formed as a ring-shaped member and is disposed around the first power part 111 and the second power part 113.

In the present disclosure, as shown in fig. 6, 9 and 11, the first power unit 111 and/or the second power unit 113 can be driven to rotate by the cleaning driving device 115. Preferably, the first power unit 111 is driven to rotate by the cleaning driving device 115, and the second power unit 113 is driven to rotate by the first power unit 111 through a ring, that is, the first power unit 111 is formed as a driving roller, and the second power unit 113 is formed as a driven roller, and the cleaning member 112.

In the present disclosure, the second power part 113 is located in front of the first power part 111 with the moving direction of the wet surface cleaning system 10 when cleaning the surface to be cleaned as front, and the outer diameter of the second power part 113 is smaller than that of the first power part 111, so that the wet surface cleaning system 10 can clean parts such as corners of walls as much as possible.

The cleaning driving device 115 may be a motor, such as a dc motor, a stepping motor, or the like, and the dc motor is preferably a dc brushless motor.

The cleaning driving device 115 may drive the first power unit 111 to rotate through a speed changing device 114, and the speed changing device 114 may be located inside the first power unit 111 or outside the first power unit 111. When the speed changing device 114 is arranged inside the first power part 111, the cleaning base 100 can be made to have a smaller volume and thereby the wet surface cleaning system 10 can be adapted to wash a surface to be cleaned in a smaller space.

The cleaning driving unit 115 may drive the speed changing unit 114 through a transmission assembly, which may be a belt transmission assembly, a chain transmission assembly, a gear transmission assembly, and the like, and is preferably a synchronous belt transmission assembly.

As shown in fig. 5, the cleaning base 100 may further include a fluid distribution module for supplying a predetermined amount of cleaning liquid to the cleaning module 110 or to a surface to be cleaned near the cleaning module 110 to supply the cleaning liquid to the surface to be cleaned by rotation of the cleaning module 110, so that the cleaning base 100 performs wet cleaning on the surface to be cleaned.

In the present disclosure, as shown in fig. 4 and 5, the fluid distribution module includes a liquid distribution module 121 and a vapor distribution module 122, wherein the liquid distribution module 121 is connected to a second fluid connection interface 250, for example, a liquid distribution connection connected to the second fluid connection interface 250. In this way, the liquid distribution module 121 can receive the cleaning liquid provided by the second fluid connection interface 250 and provide the cleaning liquid to the cleaning module 110 of the cleaning base 100 or to the surface to be cleaned near the cleaning module 110 of the cleaning base 100.

The liquid distribution module 121 may be located inside the cleaning module or outside the cleaning module 110, for example, behind the cleaning module 110. And the outlet of the liquid distribution module is located on or adjacent to an outer surface of the cleaning module.

The steam distribution module 122 is connected to the second fluid connection interface 250 or the second thick film heater 125 of the cleaning base 100, for example, the steam distribution module 122 can be connected to the steam distribution connection of the second fluid connection interface 250, at which time the first thick film heater 480 can receive the cleaning liquid stored in the cleaning liquid storage 320 and heat the cleaning liquid and generate steam, which is provided to the first fluid connection interface, and further, through the connection of the first fluid connection interface and the second fluid connection interface, is delivered to the steam distribution module 122, and further, the steam is provided by the steam distribution module 122 to the surface to be cleaned near the cleaning module 110 of the cleaning base 100.

On the other hand, the vapor distribution module 122 may also be connected to the second thick film heater 125 and may receive the vapor generated by the second thick film heater 125, in this case, the second thick film heater 125 may be connected to the second fluid connection interface 250, for example, a liquid distribution connection connected to the second fluid connection interface 250, the cleaning liquid stored in the cleaning liquid storage 320 may be provided to the first fluid connection interface 420, for example, the cleaning liquid may be provided to the liquid distribution connection of the first fluid connection interface 420, and further provided to the second thick film heater 125 through the connection of the first fluid connection interface 420 and the second fluid connection interface 250, and of course, the cleaning liquid may also be provided to the liquid distribution module 121.

As an implementation form, the liquid distribution module 121 may be a spray head or the like, thereby being capable of spraying the cleaning liquid to the cleaning member 112 or the surface to be cleaned in the vicinity of the cleaning member 112. The steam distribution module 122 may include a plurality of spray holes located in front of the cleaning member 112, so that steam can be sprayed to the surface to be cleaned in front of the cleaning member 112 through the plurality of spray holes to soften the stain of the surface to be cleaned by the steam, thereby improving the cleaning effect of the cleaning member 112 on the surface to be cleaned.

In the present disclosure, as shown in fig. 5, the fluid distribution module may further include a distribution pump 124, and the distribution pump 124 may be a peristaltic pump or the like, so that the pressure of the cleaning liquid delivered to the liquid distribution module 121 can be increased by the peristaltic pump, so that the cleaning liquid can be uniformly sprayed on the cleaning member 112 or the surface to be cleaned, and the cleaning liquid in the pipeline for delivering the cleaning liquid can be prevented from flowing backwards by the arrangement of the peristaltic pump, so that the wet surface cleaning system 10 is safer in use. That is, at this time, the dispensing pump 124 can be connected to a second fluid connection, such as a liquid dispensing connection, connected to the second fluid connection.

More preferably, as shown in fig. 5, the fluid distribution module may further include a second thick film heater 125 to heat the cleaning liquid into steam through the second thick film heater 125 and provide the steam to the steam distribution module 122; of course, the second thick film heater 125 may be replaced with another heater. In the present disclosure, the second thick film heater 125 may also be connected to a second fluid connection interface, such as a liquid dispensing connection connected to the second fluid connection interface, by a dispensing pump 124. The dispensing pump 124 may be the same dispensing pump 124 as the dispensing pump 124 described above, or a separate dispensing pump 124 may be used; more preferably, when the same dispensing pump 124 is used, a first switching valve is provided to a pipe between the dispensing pump 124 and the liquid dispensing module 121, and a second switching valve is also provided to a pipe connecting the dispensing pump 124 and the second thick film heater 125, so that the cleaning liquid is supplied to the liquid dispensing module 121 and/or the second thick film heater 125 by controlling the first switching valve and the second switching valve.

In the present disclosure, a third switch valve may be disposed on a pipeline between the steam distribution module 122 and the steam distribution connection portion of the second fluid connection interface 250, and correspondingly, a fourth switch valve may be disposed on a pipeline between the second thick film heater and the steam distribution module 122, so as to select different steam supply modes by controlling the third switch valve and the fourth switch valve.

The first switch valve, the second switch valve, the third switch valve and the fourth switch valve may be solenoid valves or electric switch valves, so that a user can control the switch valves conveniently.

When the fluid dispensing module includes the second thick film heater 125, the cleaning liquid may be provided only to the cleaning base, in which case both the dispensing pump 124 and the second thick film heater 125 may be connected to the second fluid connection interface 250, wherein the second fluid connection interface 250 may include only the liquid dispensing connection.

Accordingly, when the fluid distribution module does not include the second thick film heater 125, it is necessary to provide cleaning liquid to the liquid distribution module 121 and steam to the steam distribution module 122, and at this time, the second fluid connection interface 250 includes a liquid distribution connection and a steam distribution connection, and accordingly, the liquid distribution module 121 may be connected to the liquid distribution connection and the steam distribution module may be connected to the steam distribution connection.

In the present disclosure, the second thick film heater 125 is disposed horizontally or substantially horizontally, so that the second thick film heater 125 has a better heating effect on the cleaning liquid.

The cleaning base 100 of the present disclosure may further include a dirt suction module 130, and the dirt suction module 130 is provided with a negative pressure for collecting and sucking dirt (e.g., dust, hair, etc.) after the cleaning module cleans the surface to be cleaned into the dirt suction module, thereby preventing the cleaning base 100 from leaving stains such as used cleaning liquid on the surface to be cleaned after cleaning the surface to be cleaned. That is, when the cleaning base 100 cleans the surface to be cleaned, the recovery liquid, i.e., the cleaning liquid used when the cleaning base 100 cleans the surface to be cleaned, and the dirt, i.e., the solid waste (e.g., dust, hair, etc.) on the surface to be cleaned, are generated, and at this time, the dirt suction module 130 is formed as a recovery inlet for recovering the liquid and the dirt.

In one embodiment, as shown in fig. 7, the fluid dispensing module and the dirty intake module 130 are provided independently of each other, i.e. the fluid dispensing module is not integrated in the dirty intake module 130. Of course, the wet surface cleaning system 10 is also capable of dry cleaning a surface to be cleaned when the fluid distribution module is not providing cleaning liquid to the cleaning module 110.

Preferably, the dirt suction module 130 is disposed at the rear of the cleaning module 110 to facilitate recovery of liquid and dirt.

The cleaning base 100 of the present disclosure may further include a housing module 140, the housing module 140 forming at least a portion of an outer surface of the cleaning base 100. The nozzle holes are formed at the front end of the housing module 140 so that the front end of the housing module 140 is formed as a steam distribution module, but the steam distribution module 122 may be formed as a separate member and mounted at the front end of the housing module 140.

The housing module 140 is formed with an accommodation space, which may also be referred to as a brush chamber, in which the cleaning module 110 is located. When the suction source 330 is operated, the accommodating space communicates with the soil suction module to form a vacuumized state, and the surface to be cleaned and the soil on the cleaning module 110 are sucked to the recovery storage part 340.

The housing module 140 of the present disclosure can also provide support for the cleaning module 110, the fluid distribution module, and the dirt intake module 130 described above, and can also provide support for the cleaning drive 115, the transmission assembly, and the like.

Thus, one end of the first power part 111 may be rotatably provided to the housing module 140; accordingly, when the cleaning module 110 includes the second power part 113, i.e., the cleaning module 110 is formed as a crawler type cleaning member, one end of the second power part 113 is also rotatably provided to the housing module 140.

Meanwhile, the other end of the first power part 111 may be rotatably disposed at the bracket part 170, and when the bracket part 170 is disposed at the housing module 140, the first power part 111 is located in the brush chamber.

Similarly, when the cleaning module 110 includes the second power part 113, that is, when the cleaning module 110 is formed as a crawler type cleaning member, the other end of the second power part 113 is also rotatably provided to the bracket part 170, so that the first and

second power parts

111 and 113 are located in the brush chamber when the bracket part 170 is mounted to the housing module 140.

Moreover, at least a portion of the transmission 114 slides inside the first power portion 111, and thus a mechanical connection between the transmission 114 and the second power portion 113 is achieved.

The belt transmission assembly may include a driving synchronous pulley 116, wherein the driving synchronous pulley 116 is mounted on the cleaning driving device 115, and the driving synchronous pulley 116 is driven by the cleaning driving device 115 to rotate; in the present disclosure, the cleaning driving device 115 and the driving timing pulley 116 are respectively located at both sides of the housing module 140. Specifically, the cleaning drive device 115 is located inside the housing module 140, and the driving timing pulley 116 is located outside the housing module 140.

The driving timing pulley 116 drives the driven timing pulley 117 to rotate, the driven timing pulley 117 is mounted at one end of a transmission shaft rotatably provided to the housing module 140, and the transmission shaft is formed as an input shaft of the transmission device 114 or can input a driving force to the transmission device 114.

More preferably, the actuator is selectively engageable with an in-place signal of the subassembly 300 to block the line providing cleaning liquid, steam, or negative pressure to the cleaning base and direct fluid to the interface portion 390 after the subassembly 300 is disengaged from the support assembly 200.

Accordingly, the actuator can also selectively block the line supplying cleaning liquid, the line supplying steam or the line supplying underpressure to the attachment, i.e. block the respective sub-interfaces. For example, when the sub-assembly 300 is mounted to the support assembly 200, the actuator is driven to block a line that supplies cleaning liquid, a line that supplies steam, or a line that supplies negative pressure to the attachment.

In one instance, the actuator can be engaged with an actuating portion of the connecting end of the flexible hose, at which time, when the connecting end of the flexible hose is connected to the interface portion 390, a line providing cleaning liquid, a line providing steam, or a line providing negative pressure to the cleaning base is blocked and fluid is directed to the interface portion 390.

In another case, the wet surface cleaning system 10 may include an in-place detection device, which may be a hall sensor or a travel switch, etc., that is triggered when the sub-assembly 300 is mounted to the support assembly 200, at which time the actuator is driven to block a line for supplying cleaning liquid, a line for supplying steam, or a line for supplying negative pressure to the attachment, and open a line for supplying cleaning liquid, a line for supplying steam, or a line for supplying negative pressure to the cleaning base 100; conversely, when the presence detecting means is not activated, the actuator is driven to block the line supplying the cleaning liquid, the line supplying the steam or the line supplying the negative pressure to the cleaning base and to open the line supplying the cleaning liquid, the line supplying the steam or the line supplying the negative pressure to the attachment.

In the present disclosure, the bottom surface of the sub-assembly is formed in a substantially square or circular shape, and the first recovery connection portion 410, the first electrical component 440, the first circuit interface 470, and the second fluid connection interface 250 may be disposed on the bottom surface of the sub-assembly 300.

Accordingly, the support platform 210 of the support assembly 200 is formed as a reverse tapered body having a substantially square or circular cross-section, and a lower end surface of the reverse tapered body (i.e., a lower surface of the support platform 200) is longitudinally spaced from an upper surface of the cleaning base 100, and accordingly, the second recovery connection portion, the second electrical component, the second circuit interface, the first fluid connection interface, and the like may be disposed at an upper wall position of the support platform 210.

The wet surface cleaning system 10 of the present disclosure may be operatively mounted to the support assembly 200 prior to operation, or may be separated from the support assembly 200 for use as a stand alone wet surface cleaning apparatus. When the sub-assembly 300 is mounted to the support assembly 200, various connections between the component systems may be made simultaneously, including but not limited to fluid transport interconnections, recycling interconnections, electrical system interconnections.

More specifically, when the subassembly 300 is operatively mounted to the support assembly 200, the cleaning liquid reservoir 320 is connected to the fluid distribution module of the cleaning base 100 such that cleaning fluid (liquid and/or gas-liquid mixture) can be distributed to the cleaning module 110 and/or the floor surface. The recovery storage part 340 is connected to the soil suction module 130 of the cleaning base 100 such that the vacuuming airflow generated by the suction source 330 is sucked into the recovery storage part 340 through the soil suction module 130. Also, the first circuit interface 470 and the second circuit interface 270 of the subassembly 300 are connected to deliver electrical power to the cleaning drive, the fluid distribution module, or the second thick film heater 125, etc. of the cleaning base 100.

In one case, a mains AC power supply is connected directly to the rechargeable battery module of the sub-assembly 300 via a power cord and an AC/DC converter, so that mains power can simultaneously power the cleaning base 100 and the sub-assembly 300, in which case an AC/DC converter may be provided to the support assembly 200 to perform various cleaning functions.

The user fills the cleaning liquid storage 320 with at least one cleaning liquid. In order for the cleaning liquid storage part 320 to store the cleaning liquid, the cleaning liquid storage part 320 may be configured such that the cleaning liquid storage part 320 can be connected with the first fluid interface by taking out the cleaning liquid storage part 320 from the sub-assembly 300, then filling the cleaning liquid into the cleaning liquid storage part 320, and then mounting the cleaning liquid storage part 320 filled with the cleaning liquid to the side of the sub-assembly 300.

To operate the wet surface cleaning system 10 in a floor cleaning mode, with the subassembly 300 mounted on the support assembly 200, a user actuates a main power switch on the handle or on the subassembly to provide power from a power source (such as a rechargeable battery module or a house outlet of the subassembly) to power the suction source 330 so that the negative pressure generated by the suction source 330 generates a working air flow through the recovery storage 340. In addition, when the sub-assembly 300 is mounted on the support assembly 200, power is supplied to the cleaning base 100 through the sub-assembly 300. As described above, the electrical connection of the sub-assembly 300 and the cleaning base 100 is achieved through the mating first and second circuit interfaces.

The power supplied from subassembly 300 can energize electrical components including first thick film heater 480, brush motor, brushless motor, PCB board, pump, lights, LED/LCD display screen, speakers, sensors.

In the on state with the sub-assembly 300 on the support assembly 200, a user grasps the handle and moves the wet surface cleaning system 10 along a surface to be cleaned. By dispensing a cleaning fluid at normal or high temperature to the floor or cleaning base 100 while the cleaning module is rolling against the surface to be cleaned.

The cleaning fluid and suction power may be selectively dispensed by providing, for example, a visual sensor, an ultrasonic sensor, a TOF sensor, an infrared sensor, etc., through interaction of the sensor with the floor barrier, the floor material, etc. Used cleaning fluid and dirt on the floor to be cleaned is brought into the working air flow by the dirt suction module on the cleaning base and removed, and enters the recovery storage part 340 through the fluid flow passage, the used cleaning fluid and dirt are separated from the working air in the recovery storage part 340, and the solid dirt and the liquid dirt are separated by the solid-liquid separator in the recovery tank. The working air continues to flow out of the recovery storage 340 along the working air exhaust path to the suction source 330, and the exhaust air from the suction source 330 continues to flow out of the airflow outlet of the subassembly 300.

The user discards the used cleaning fluid and dirt into the appropriate receptacle and drain by removing the recovery storage 340 from the side of the sub-assembly 300 and emptying the recovery tank at the appropriate location.

To operate the wet surface cleaning system 10 in a portable assisted cleaning mode, a user removes the subassembly 300 from the support assembly 200 by depressing a latch button on the subassembly 300 or the support assembly 200.

When used to remove the sub-assembly 300 from the support assembly 200, the cleaning liquid reservoir 320, the suction source 330, the recovery reservoir 340, the first thick film heater 480, etc. may all be in communication with the interface portion 390 of the sub-assembly 300. The first and second circuit interfaces of the subassembly 300 and the support assembly 200 are separated, thereby disconnecting power to the cleaning base 100.

To prevent user error, the suction source 330 is deactivated after the latch button is triggered. And there is no fluid interaction between the second fluid coupling interface 250 and the interface portion until the user installs the flexible hose of the accessory and presses the start switch again.

When it is desired to operate the sub-assembly 300 alone, the user installs the flexible hose of the accessory to the interface portion 390 of the sub-assembly 300 and activates the switch, the interface portion 390 having fluid interaction therein and being capable of providing cleaning liquid and/or steam, etc. to the accessory and drawing used recovery liquid and dirt from the accessory and into the recovery reservoir 340.

Thus, the wet surface cleaning system 10 of the present disclosure can be formed as a multi-purpose wet surface cleaning system 10, providing an unlimited number of application possibilities for conventional upright wet surface cleaning apparatuses. The subassembly is compact and lightweight, thereby simplifying its use.
