Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The surface cleaning device related to the embodiment of the application can be a self-moving surface cleaning device such as a window cleaning robot, a floor sweeping robot and the like; alternatively, a non-self-moving surface cleaning device that requires the user to drag or hold in hand. The product form is not particularly limited in the examples of the present application.

Referring to fig. 1, a partial structural schematic view of a surface cleaning apparatus provided in an embodiment of the present application is shown; referring to fig. 2, an exploded view of the partial structure shown in fig. 1 is provided for an embodiment of the present application. As shown in fig. 1 in conjunction with fig. 2, the surface cleaning apparatus 100 includes an upper housing 161, the upper housing 161 being a portion of the housing of the surface cleaning apparatus 100. It will be appreciated that surface cleaning apparatus 100 will typically further include a lower housing (not shown) that snaps upper housing 161 and lower housing together to form the interior space of surface cleaning apparatus 100.

A cleaning liquid containing tank 162 is provided on the upper housing 161, and the cleaning liquid containing tank 162 is used to contain a cleaning liquid, which may be water or an aqueous solution added with a cleaning agent or a disinfectant, etc. In a specific implementation, the cleaning solution containing tank 162 may be detachably fixed to the upper housing 161 by screws, fasteners, interference fits, or the like, so as to facilitate the removal and replacement of the cleaning solution containing tank 162.

Cleaning solution holding box 162 includes the liquid outlet, and the liquid outlet of cleaning solution holding box 162 is linked together through the inlet of transfer line 164 with cleaning solution output module 163 for the cleaning solution in cleaning solution holding box 162 can carry to cleaning solution output module 163 through transfer line 164, and then exports to treating clean surface through cleaning solution output module 163, improves the clean effect of treating clean surface. In a specific implementation, the cleaning liquid output module 163 may be a spray head, an ultrasonic spray sheet, a water dropping hole, or the like, which is not limited in this embodiment.

In one possible embodiment, the cleaning liquid outlet module 163 is connected to a side wall of the upper housing 161. Specifically, the cleaning liquid delivery module 163 passes through the sidewall of the upper housing 161 such that the outlet of the cleaning liquid delivery module 163 is located outside the upper housing 161, facilitating spraying of the cleaning liquid to the outside of the surface cleaning apparatus 100; the cleaning solution outlet module 163 has its inlet port located inside the upper housing 161 for connection to the fluid line 164. In a specific implementation, the cleaning liquid output module 163 may be detachably connected to the upper housing 161 by screws, snaps, interference fits, or the like, so as to facilitate the detachment and replacement of the cleaning liquid output module 163.

It can be understood that when the cleaning liquid in the surface cleaning apparatus 100 is exhausted, it is necessary to control the surface cleaning apparatus 100 to stop the cleaning operation and remind the user to add the cleaning liquid to avoid the cleaning mode of the surface cleaning apparatus 100 changing to dry cleaning, which affects the cleaning effect.

In order to detect the cleaning liquid in the surface cleaning device 100, a liquid detection module is usually disposed in the cleaning liquid containing tank 162 in the prior art (for the convenience of distinguishing from the liquid detection module disposed outside the cleaning liquid containing tank 162, the liquid detection module is referred to as a second liquid detection module), and the presence or absence of the cleaning liquid in the cleaning liquid containing tank 162 can be detected in real time by the second liquid detection module.

However, when cleaning solution is present in cleaning solution containing tank 162, there may be no cleaning solution in tubing 164. For example, when surface cleaning apparatus 100 is first used or not used for an extended period of time, cleaning solution is present in cleaning solution containing tank 162, but not in infusion line 164. At this time, if the surface cleaning apparatus 100 is controlled to perform the cleaning operation, the cleaning mode of the surface cleaning apparatus 100 is changed to dry cleaning, and the cleaning effect is poor. Alternatively, when cleaning liquid is not present in cleaning liquid containing tank 162, cleaning liquid may be present in tubing 164. For example, when the cleaning solution in the cleaning solution containing tank 162 is depleted, residual cleaning solution may still be present in the infusion line 164. At this time, if the surface cleaning apparatus 100 is controlled to stop cleaning, the cleaning liquid may remain, and the remaining cleaning liquid may cause a problem such as odor if it is not cleaned for a long time.

In view of the above problem, in the embodiment of the present application, a liquid detection module is disposed outside the cleaning liquid containing box 162 (for the convenience of distinguishing from the liquid detection module disposed in the cleaning liquid containing box 162, the liquid detection module is referred to as a first liquid detection module 166), and the first liquid detection module 166 is used for detecting whether the cleaning liquid exists in the liquid conveying pipe 164, so as to obtain a more accurate detection result. For example, when surface cleaning apparatus 100 is first used or not used for an extended period of time, cleaning solution is present in cleaning solution containing tank 162, but not in infusion line 164. At this time, if the first liquid detecting module 166 detects that the cleaning liquid is not present in the liquid pipe 164, the surface cleaning apparatus 100 may be controlled to stop performing the cleaning operation. As another example, when the cleaning solution in the cleaning solution containing tank 162 is exhausted, residual cleaning solution may still be present in the liquid delivery tube 164. At this time, if the detection result of the first liquid detection module 166 is that the cleaning liquid is present in the liquid delivery tube 164, the surface cleaning device 100 can be controlled to continue the cleaning operation until the cleaning liquid in the liquid delivery tube 164 is exhausted, so as to avoid the residual cleaning liquid in the liquid delivery tube 164.

In practice, the infusion tube 164 has a certain length, and the position of the first fluid detection module 166 determines the detection position of the infusion tube 164.

Referring to fig. 3A, a schematic diagram of a position where a first liquid detection module is disposed is provided in an embodiment of the present application. As shown in fig. 3A, the first liquid detection module 166 is disposed at position a, and the first liquid detection module 166 can detect whether cleaning liquid is present at position a of the infusion tube 164. Referring to fig. 3B, a schematic diagram of a position where another first liquid detection module is disposed is provided in the embodiment of the present application. As shown in fig. 3B, the first liquid detection module 166 is disposed at position B, and the first liquid detection module 166 can detect whether cleaning liquid is present at position B of the infusion tube 164.

It can be understood that the closer the first liquid detection module 166 is disposed to the cleaning liquid output module 163, the more accurate the detection result of the first liquid detection module 166 is. In other words, the closer the first liquid detection module 166 is disposed to the cleaning liquid output module 163, the more accurately the detection result of the first liquid detection module 166 can reflect whether the cleaning liquid output module 163 can output the cleaning liquid.

Referring to fig. 4A, a schematic view of an application scenario provided in the embodiment of the present application is shown; referring to fig. 4B, a schematic view of another application scenario provided in the embodiment of the present application is shown. In the application scenario shown in fig. 4A and 4B, cleaning solution is present at the end of the fluid line 164 near the cleaning solution containing tank 162, and air is present at the end of the fluid line 164 near the cleaning solution output module 163 (no cleaning solution is present).

In fig. 4A, the first liquid detecting module 166 is disposed at position a, and at this time, since air is present in the liquid conveying pipe 164 at position a, the detection result of the first liquid detecting module 166 is that no cleaning liquid is present in the liquid conveying pipe 164, and the surface cleaning device 100 can be controlled to stop performing the cleaning operation. It can be understood that, at this time, if the surface cleaning apparatus 100 performs the cleaning operation, the cleaning liquid output module 163 cannot output the cleaning liquid, and therefore, the detection result obtained by the first liquid detection module 166 is a correct detection result.

In contrast, in fig. 4B, the first liquid detecting module 166 is disposed at position B, and at this time, since the cleaning liquid is in the liquid conveying pipe 164 at position B, the detecting result of the first liquid detecting module 166 is that the cleaning liquid is in the liquid conveying pipe 164, so as to control the surface cleaning apparatus 100 to perform the cleaning operation. However, if the surface cleaning apparatus 100 performs the cleaning operation, the cleaning liquid output module 163 cannot output the cleaning liquid (the cleaning liquid can be output after the air in the liquid pipe 164 is exhausted), and therefore, the detection result obtained by the first liquid detection module 166 is an erroneous detection result.

Referring to fig. 5A and 5B, schematic diagrams of another application scenario provided in the embodiment of the present application are shown. In the application scenario shown in fig. 5A and 5B, the end of the fluid line 164 near the cleaning solution containing tank 162 is air (without cleaning solution), and the end of the fluid line 164 near the cleaning solution output module 163 is with cleaning solution.

In fig. 5A, the first liquid detecting module 166 is disposed at position a, and at this time, since the cleaning liquid is in the liquid conveying pipe 164 at position a, the detection result of the first liquid detecting module 166 is that the cleaning liquid is in the liquid conveying pipe 164, and the surface cleaning device 100 can be controlled to stop performing the cleaning operation. It can be understood that if the surface cleaning apparatus 100 performs the cleaning operation, the cleaning liquid output module 163 can output the cleaning liquid, so that the detection result obtained by the first liquid detection module 166 is the correct detection result.

In contrast, in fig. 5B, the first liquid detecting module 166 is disposed at position B, and at this time, since air is present in the liquid conveying pipe 164 at position B, the detection result of the first liquid detecting module 166 is that no cleaning liquid is present in the liquid conveying pipe 164, and the surface cleaning device 100 can be controlled to stop performing the cleaning operation. However, at this time, if the surface cleaning apparatus 100 performs the cleaning operation, the cleaning liquid output module 163 may output the cleaning liquid, and thus the detection result obtained by the first liquid detection module 166 is an erroneous detection result.

In summary, the closer the first liquid detecting module 166 is disposed to the cleaning liquid output module 163, the more accurate the detection result of the first liquid detecting module 166 is. Therefore, in the present embodiment, the first liquid detection module 166 can be connected to the end of the infusion tube 164 near the cleaning liquid output module 163 to obtain more accurate detection results.

With continued reference to fig. 1 and 2, in one implementation, the first liquid detection module 166 may be implemented using a photoelectric sensor. Specifically, the photoelectric sensor may include a light emitter 1662 and a light receiver 1663, with the light emitter 1662 and the light receiver 1663 being disposed on both sides of the infusion tube 164, respectively. In operation, the optical transmitter 1662 transmits an optical signal and the optical receiver 1663 receives an optical signal. Because the light transmittance of the cleaning liquid and the air is different, when the cleaning liquid is present in the infusion tube 164 and the cleaning liquid is absent, the light signal received by the light receiver 1663 is different, and it can be determined whether the cleaning liquid is present in the infusion tube 164. In specific implementation, the photoelectric sensor can be an optical coupler or a photoelectric correlation switch, and the embodiment of the application does not specifically limit the type of the selected component.

To facilitate mounting, in one possible implementation, the photosensor may be provided as a slot-type photosensor. Specifically, the groove type photoelectric sensor includes a groove type body on which a groove 1661 is provided, and a light emitter 1662 and a light receiver 1663 are respectively provided on both sides of the groove 1661. During installation, the infusion tube 164 is embedded in the groove 1661, so that the light emitter 1662 and the light receiver 1663 are respectively arranged on two sides of the infusion tube 164, and the installation is convenient.

In a specific implementation, the first liquid detection module 166 may be detachably connected to the upper housing 161 by screws, snaps, interference fits, or the like, so as to facilitate the detachment and replacement of the first liquid detection module 166. When the first liquid detection module 166 is connected by a snap, a fixing snap 168 matching with the shape/contour of the first liquid detection module 166 may be disposed on the upper housing 161, and the first liquid detection module 166 may be embedded in the fixing snap 168 to fix the first liquid detection module 166. It will be appreciated that when connected by a snap fit, removal and replacement of first liquid detection module 166 may be accomplished by a user without the aid of other tools, and is more convenient.

In one possible implementation, the surface cleaning apparatus 100 further includes a pump module 165, and the pump module 165 can provide power to deliver the cleaning liquid in the cleaning liquid containing tank 162 to the cleaning liquid output module 163. For convenience of description, the liquid pipe 164 between the cleaning liquid containing tank 162 and the pump module 165 is referred to as a first liquid pipe 1641, and the liquid pipe 164 between the pump module 165 and the cleaning liquid output module 163 is referred to as a second liquid pipe 1642. In the concrete implementation, the liquid outlet of the cleaning solution containing box 162 is communicated with the liquid inlet of the pump module 165 through the first liquid conveying pipe 1641, and the liquid outlet of the pump module 165 is communicated with the liquid inlet of the cleaning solution output module 163 through the second liquid conveying pipe 1642, so that the cleaning solution containing box 162 is communicated with the cleaning solution output module 163. In the embodiment of the present application, the first liquid detection module 166 is connected to the second liquid delivery tube 1642 at a corresponding position, that is, the first liquid detection module 166 detects whether the cleaning liquid is present in the second liquid delivery tube 1642. It can be understood that the second infusion tube 1642 is closer to the cleaning solution output module 163 than the first infusion tube 1641, and "connect the first liquid detection module 166 to a position corresponding to the second infusion tube 1642" can realize that the first liquid detection module 166 is connected to the end of the infusion tube 164 close to the cleaning solution output module 163 as described in the above embodiments.

Further, to obtain more accurate detection results, the first liquid detection module 166 may be connected to an end of the second liquid delivery tube 1642 near the cleaning liquid output module 163. For the sake of brevity, details of the operation principle of the present invention are not described herein.

In one possible implementation, the surface cleaning apparatus 100 further includes a second liquid detection module disposed within the cleaning liquid containing tank 162 for detecting whether the cleaning liquid is present within the cleaning liquid containing tank 162. That is, on the basis of the first liquid detection module 166, the second liquid detection module is added in the embodiment of the present application, so that a more accurate detection result can be obtained by the cooperation between the first liquid detection module 166 and the second liquid detection module, and the flexible control of the surface cleaning apparatus 100 can be realized, which is described in detail below in conjunction with the method embodiment.

In one possible implementation, the surface cleaning apparatus 100 further includes an alarm module for outputting an alarm message when cleaning liquid is not present in the fluid line 164 and/or cleaning liquid is not present in the cleaning liquid containing tank 162. In specific implementation, the alarm module can be a buzzer, an indicator light, a display screen and the like, and the human-computer interaction mode is not specifically limited in the embodiment of the application.

In one possible implementation, the surface cleaning apparatus 100 further includes a control module 167, the control module 167 being configured to provide data storage and data processing functions. For example, the control module 167 can determine whether to control the surface cleaning apparatus 100 to perform a cleaning operation based on the detection results of the first liquid detection module 166 and/or the second liquid detection module; alternatively, whether to output alarm information is determined based on the detection results of the first liquid detection module 166 and/or the second liquid detection module. In a specific implementation, the control module 167 may include a processor, a memory, or the like, or the control module 167 is implemented by a Micro Controller Unit (MCU), and the specific type of the control module 167 and the setting position of the control module 167 on the surface cleaning apparatus 100 are not specifically limited in this embodiment of the application.

It should be noted that, in the above embodiment, the cleaning liquid containing tank 162, the cleaning liquid output module 163, the liquid pipe 164, the pump module 165, and the first liquid detecting module 166 are disposed on the upper housing 161 as an example for explanation. It is understood that a person skilled in the art can arrange some or all of the above functional units on the lower housing according to the space limitation inside the surface cleaning apparatus 100, and all of them should fall within the protection scope of the present application.

Corresponding to the surface cleaning device 100, the embodiment of the application also provides a control method of the surface cleaning device 100.

Referring to fig. 6, a flowchart of a control method of a surface cleaning apparatus according to an embodiment of the present disclosure is shown. The method is applicable to the surface cleaning apparatus 100 of the above-described embodiment, and it should be noted that when the method is used, the first liquid detection module 166 in the surface cleaning apparatus 100 may not be disposed at the end of the liquid delivery tube 164 near the cleaning liquid delivery module 163. For example, the method embodiment may still be applied when the first liquid detection module 166 in the surface cleaning apparatus 100 is disposed at an end of the liquid line 164 near the cleaning liquid containing tank 162. As shown in fig. 6, the method mainly includes the following steps.

Step S601: whether cleaning solution exists in the infusion tube or not is detected through the first liquid detection module, and a first detection result is obtained.

It can be understood that the first liquid detection module 166 is used for detecting whether the cleaning liquid exists in the infusion tube 164, and for the sake of convenience, the detection result of the first liquid detection module 166 is referred to as a first detection result. The first detection result may include the presence of the cleaning solution in the infusion tube 164 or the absence of the cleaning solution in the infusion tube 164.

Step S602: whether cleaning solution exists in the cleaning solution containing box or not is detected through the second liquid detection module, and a second detection result is obtained.

It can be understood that the second liquid detection module is used for detecting whether the cleaning liquid is present in the cleaning liquid containing tank 162, and for the convenience of distinguishing, the detection result of the second liquid detection module is referred to as a second detection result. The second detection result may include the presence of the cleaning liquid in the cleaning liquid containing tank 162 or the absence of the cleaning liquid in the cleaning liquid containing tank 162.

Step S603: and judging whether the cleaning liquid exists in the surface cleaning device according to the first detection result and the second detection result.

Specifically, if the first detection result is that the cleaning solution is present in the liquid conveying pipe 164 or the second detection result is that the cleaning solution is present in the cleaning solution containing tank 162, it is determined that the cleaning solution is present in the surface cleaning device 100; if the first detection result is that the cleaning solution does not exist in the infusion tube 164 and the second detection result is that the cleaning solution does not exist in the cleaning solution containing tank 162, it is determined that the cleaning solution does not exist in the surface cleaning device 100. The comparison relationship between the first detection result, the second detection result and the comprehensive judgment result is shown in the table I.

Table one:

step S604: and if the cleaning liquid exists in the surface cleaning device, controlling the surface cleaning device to perform cleaning operation.

As shown in the first table above, when it is determined that cleaning liquid is present within the surface cleaning apparatus 100, there are three situations as follows.

Firstly, the method comprises the following steps: the cleaning solution is present in the fluid line 164 and the cleaning solution is present in the cleaning solution containing tank 162.

It is appreciated that cleaning liquid output module 163 can output cleaning liquid when surface cleaning apparatus 100 is performing a cleaning operation when cleaning liquid is present in both fluid line 164 and cleaning liquid holding tank 162. Therefore, the surface cleaning apparatus 100 can be controlled to perform the cleaning operation in this case.

Secondly, the method comprises the following steps: the cleaning solution is present in the fluid line 164 and is not present in the cleaning solution containing tank 162.

For example, the cleaning fluid in the cleaning fluid tank 162 is exhausted, but the cleaning fluid remains in the infusion tube 164. At this time, the surface cleaning apparatus 100 is controlled to perform the cleaning operation, and the cleaning liquid output module 163 can output the cleaning liquid (i.e. the surface cleaning apparatus 100 can perform the normal cleaning operation), and can ensure that the cleaning liquid in the infusion tube 164 is used up, so as to avoid the residual cleaning liquid in the infusion tube 164.

Thirdly, the steps of: the cleaning liquid is not present in the liquid pipe 164, and the cleaning liquid is present in the cleaning liquid containing tank 162.

For example, when the surface cleaning apparatus 100 is used for the first time, the cleaning solution in the cleaning solution containing tank 162 is not delivered into the infusion tube 164, so that the cleaning solution is not present in the infusion tube 164; alternatively, when the surface cleaning apparatus 100 is not used for a long time, the cleaning liquid in the liquid pipe 164 evaporates or flows back into the cleaning liquid containing tank 162, so that the cleaning liquid does not exist in the liquid pipe 164. At this time, the surface cleaning apparatus 100 is controlled to perform the cleaning operation, and although the cleaning liquid is not output from the cleaning liquid output module 163 at the initial time, the cleaning liquid can be delivered to the cleaning liquid output module 163 from the cleaning liquid containing tank 162 after the surface cleaning apparatus 100 is operated for a short time, so that the normal cleaning operation can be performed. On the contrary, if it is judged that no cleaning liquid exists in the surface cleaning device 100 under the condition, the alarm information is output to remind the user of adding the cleaning liquid, so that misjudgment can be obviously generated, and the user experience is influenced.

In one possible implementation, when the cleaning solution is not present in the infusion tube 164 and the cleaning solution is present in the cleaning solution containing tank 162, the pump module 165 may be first controlled to operate for a predetermined time T, and then the cleaning operation is performed. During the predetermined time T during which the pump module 165 operates, the pump module 165 can deliver the cleaning liquid from the cleaning liquid containing tank 162 to the cleaning liquid output module 163, so as to ensure that the cleaning liquid output module 163 can output the cleaning liquid when the surface cleaning apparatus 100 performs the cleaning operation. Due to the power of the pump module 165 and the length of the infusion tube 164, after the pump module 165 starts to operate, the time for delivering the cleaning liquid from the cleaning liquid containing tank 162 to the cleaning liquid output module 163 can be determined through a plurality of tests, and then the preset time T can be determined.

In one possible implementation, when the cleaning liquid is not present in the liquid pipe 164 and the cleaning liquid is present in the cleaning liquid containing tank 162, the operation of the pump module 165 may be controlled first. When it is determined that the cleaning solution is present in the fluid line 164, the cleaning operation is resumed to ensure that the cleaning solution output module 163 can output the cleaning solution when the surface cleaning apparatus 100 performs the cleaning operation.

Step S605: and if the cleaning liquid is not present in the surface cleaning device, controlling the surface cleaning device to stop executing the cleaning operation.

As shown in the first table above, when it is determined that cleaning liquid is not present in the surface cleaning apparatus 100, there are only the following: no cleaning liquid is present in the liquid line 164 and no cleaning liquid is present in the cleaning liquid containing tank 162. In this case, it is described that the cleaning liquid in the surface cleaning apparatus 100 is exhausted, the surface cleaning apparatus 100 needs to be controlled to stop performing the cleaning operation, so as to prevent the surface cleaning apparatus 100 from affecting the cleaning effect due to the long-time processing of the dry cleaning mode.

In one possible implementation, when it is determined that cleaning liquid is not present within the surface cleaning device 100, an alert message may also be output to prompt the user to add cleaning liquid.

In the embodiment of the present application, the cleaning solution state in the cleaning solution containing box 162 and the infusion tube 164 is combined to control the surface cleaning device 100, so as to better conform to the actual application scene, thereby avoiding causing misjudgment and influencing the cleaning effect.
