The following describes the technical scheme provided by the embodiment of the application with reference to the accompanying drawings.

Currently, the most advanced cleaning robots on the market are matched with workstations. In order to prevent the dust from entering the blower, a cleaning robot or a workstation body is generally provided with a filter such as a dust box or a dust bag to filter and collect the solid dust such as dust and debris.

In the prior art, in order to avoid the filter being neglected by users, sensors such as photoelectric sensors, pull-wire sensors, pressure sensors and the like are generally used to detect whether the filter is mounted on the body. However, the above-described in-place detecting sensor can only detect whether the filter is mounted in place, and cannot identify the specific type of filter mounted in place. Based on this, the present application provides a cleaning device capable of detecting the type of filter element mounted in place.

It should be noted that, the cleaning device 100 referred to herein may be a cleaning robot or a workstation used with the cleaning robot, because in the field of household cleaning robots, a garbage recycling system including a dust bag is usually disposed on the workstation to recycle and empty the garbage temporarily stored in the dust bag in the cleaning robot, whereas in the field of commercial cleaning robots, the dust bag is usually disposed directly in a sewage tank on the cleaning robot body, the workstation only needs to cooperate with the robot to discharge the sewage liquid stored in the sewage tank of the robot after being filtered by the dust bag. Therefore, the cleaning apparatus 100 provided by the present application is not limited to the cleaning robot. Of course, it should be noted that the cleaning device 100 in the drawings is only a part of the structure of the cleaning robot, and not the entire structure.

As shown in fig. 1-2, one embodiment of the present application provides a cleaning device 100, the cleaning device 100 including a body 110, a plurality of different types of filter members 120, a magnetic member 130, a hall sensor 140, and a control module (not shown in the drawings, hereinafter).

Wherein, the plurality of different types of filter elements 120 can alternatively be mounted on the body 110, i.e. the filter element 120 has a first state separated from the body 110 and a second state mounted on the body 110. When the filter 120 is mounted on the body 110, the filter 120 can filter and collect solid wastes such as dust, debris, etc., recovered by a blower (not shown in the drawings, hereinafter, the same) through a dirt suction pipe (not shown in the drawings, hereinafter, the same).

When any filter 120 is mounted on the body 110, the hall sensor 140 corresponds to the position of the magnetic member 130, and the hall sensor 140 can be used for detecting the intensity of the stable magnetic field formed by the magnetic member 130 due to the stable distance between the hall sensor 140 and the magnetic member 130.

The control module is in signal connection with the hall sensor 140, and can judge the type of the filter 120 installed on the body 110 according to the intensity of the magnetic field detected by the hall sensor 140.

In the above-mentioned cleaning device 100, since the cleaning device includes a plurality of different types of filter elements 120, and each filter element 120 is provided with a magnetic element 130 with a different magnetic field intensity, when any filter element 120 is mounted on the body 110, the hall sensor 140 corresponding to the position of the magnetic element 130 can detect the magnetic field intensity formed by the magnetic element 130 on the filter element 120 after the filter element 120 is mounted, and the control module can receive the magnetic field signal detected by the hall sensor 140, and can determine the type of the filter element 120 mounted in place according to the magnetic field intensity. That is, if the control module receives that the magnetic field strength detected by the hall sensor 140 is within the preset range, it indicates that the filter 120 is installed in place; and because the magnetic pieces 130 capable of forming different magnetic field intensities are arranged on the different types of filter pieces 120, after the filter pieces 120 are installed in place, the control module can effectively judge the type of the filter piece 120 installed in place according to the difference of the magnetic field intensities.

Specifically, taking as an example the type discrimination of two different types of filter elements 120:

two different types of filter elements 120 are defined as class a filter elements and class B filter elements, respectively; wherein, the A-type filter element comprises a bracket 121 and non-woven fabrics paved on the bracket 121, and the A-type filter element is provided with a magnetic element 130 with stable magnetic flux of 200Wb-400Wb; the B-type filter element comprises a bracket 121 and nylon cloth paved on the bracket 121, and the B-type filter element is provided with a magnetic element 130 with stable magnetic flux of 400Wb-800Wb. Since the magnetic field intensity formed by the magnetic member 130 is related to the magnetic flux intensity, the magnetic flux intensity formed by the magnetic member 130 disposed on the filter member 120 of different types is different, and the magnetic field intensity formed by the magnetic member 130 disposed on the filter member 120 is detected, that is, the magnetic field intensity formed by the magnetic member 130 disposed on the filter member 120 is detected. When the filter 120 is mounted on the body 110, if the control module receives the magnetic field detected by the hall sensor 140 within the range of 200Wb-400Wb, it indicates that the filter 120 is mounted in place, and the filter 120 mounted on the body 110 is a type a filter; similarly, if the control module receives a magnetic flux in the range of 400Wb-800Wb detected by the Hall sensor 140, it indicates that the filter 120 is installed in place, and the filter 120 installed on the body 110 is a class B filter. Conversely, if the control module receives the magnetic field detected by the hall sensor 140 with a magnitude of 0 or weak, that is, the magnetic field detected by the hall sensor 140 with a magnitude of 0 or weak, it indicates that the filter 120 is not in place. Of course, the intensity of the magnetic field that can be formed by the different types of filter elements 120 can be specifically set according to the needs of the user, and whether the other types of filter elements 120 are in place or not can be detected by the similar method as described above, and will not be described herein.

It will be appreciated that the cleaning device 100 may be equipped with a variety of different types of filters 120 depending on different job scenarios or cleaning job tasks, such as: for the operation scene that garbage with larger size exists in the large probability of kitchen, operation room and the like, the filter 120 with smaller mesh number or stronger filterability is used, for example: a screen type filter; and to the operation scene that only has rubbish such as earth, dust to big probability such as market hall, vestibule, can be equipped with and use the filter 120 that mesh is great or the permeability is slightly weak, if: a non-woven filter element.

In one embodiment, the main body 110 is provided with a dirt collecting chamber 111, and any of the filtering members 120 can be alternatively disposed in the dirt collecting chamber 111.

As shown in fig. 3, in one embodiment, the filter element 12 is a basket-like structure with an open top, and a cover (not shown in the drawings, the same applies below) may be provided on the opening alone, or the cover of the body 110 may be capable of sealing the cover in a relatively sealed configuration; the different types of filter elements 12 each have different filterability.

With continued reference to fig. 3, in one embodiment, the filter 120 includes a support 121 and a filter screen 122 embedded on the support 121. The support 121 serves as a framework material of the filter 120, and can support the filter screen 122, so that the filter screen 122 can be laid and fixed on the support 121. That is, the support 121 is a hollow structure, and a plurality of through holes 123 are formed on the support 121, when the filter screen 122 is disposed on the support 121, the filter screen 122 is fully paved with all the through holes 123, and at this time, the filter screen 122 and the support 121 together enclose a dust storage space 124.

Further, in an embodiment, the filter 120 is detachably disposed in the dirt collecting chamber 111, for example, the filter 120 may be detachably mounted in the dirt collecting chamber 111 of the body 110 by plugging, hanging, magnetic attraction, adhesion, etc. In this way, the filtering member 120 is convenient for separating and filtering the solid waste contained in the gas and the liquid flow, so that the solid waste such as dust and debris is collected in the dust storage space 124 of the filtering member 120, and the gas and the liquid filtered by the filter 122 are discharged out of the body 110 through the filter 122 or are collected in the dirt collecting cavity 111 on the body 110. The filter element 120 is filled with waste, and the filter element 120 can be removed from the dirt collection chamber 111, replaced with a new filter element 120, or the filter element 120 can be cleaned.

Referring again to fig. 1-3, the magnetic member 130 is disposed on the outer surface of the filter element 120. The magnetic field strength detection precision of the Hall sensor 140 on the magnetic piece 130 can be improved, and the reliability of discriminating the type of the filter piece 120 is ensured. Specifically, the magnetic member 130 may be manufactured by processing a common magnetic material such as a magnet and a magnetic steel.

Further, the magnetic member 130 is detachably mounted on the filter 120, for example, the magnetic member 130 is mounted on the bracket 121 of the filter 120 by means of clamping, embedding, etc. Because the magnetic pieces 130 are detachably mounted on the filter pieces 120, on one hand, the number of the magnetic pieces 130 on the filter pieces 120 and the mounting direction of the magnetic pieces 130 can be adjusted in a detachable manner, and on the other hand, the filter pieces 120 are used as consumable materials which are filled and thrown, but the magnetic pieces 130 on the filter pieces 120 can be recycled. Of course, the magnetic member 130 may also be fixed on the filter element 120, for example, the magnetic member 130 is fixedly disposed on the bracket 121 of the filter element 120 by adhesion or the like. The magnetic member 130 is fixed to prevent it from falling off or even losing.

In one embodiment, as shown in fig. 1 and 2, the hall sensor 140 is disposed on the body 110. Specifically, the hall sensor 140 may be mounted and fixed on the body 110 by means of clamping, embedding, welding, etc. When any filter 120 is mounted on the body 110, the hall sensor 140 corresponds to the magnetic member 130 at intervals, so as to detect the intensity of the magnetic field formed by the magnetic member 130, and feed back to the control module to determine whether the filter 120 is in place or not and whether the filter is of a type.

To determine whether the filter 120 is in place and the type of filter 120, in one embodiment, the control module includes a control circuit (not shown, the same applies hereinafter) and a receiver (not shown, the same applies hereinafter) that are in signal communication. The control circuit is in signal connection with the hall sensor 140, and the control circuit is used for converting the magnetic field signal detected by the hall sensor 140 into an electric signal and outputting the electric signal to the receiver, and the receiver judges the type of the filter 120 mounted on the body 110 according to the received electric signal. The control circuit may convert the magnetic field signal detected by the hall sensor 140 into a voltage signal or a current signal for the receiver to receive, and the receiver determines the type of the filter 120 mounted on the body 110 according to the magnitude of the received voltage signal or current signal.

In a preferred embodiment, a plurality of magnetic members 130 are disposed on any one of the filter members 120, and the plurality of magnetic members 130 are disposed on the outer surface of any one of the filter members 120 at intervals. By arranging different numbers of magnetic pieces 130 on the outer surface of the filter piece 120, under the combined action of the magnetic pieces 130, after the filter piece 120 is installed in place, the magnetic pieces 130 on different types of filter pieces 120 can be combined to form magnetic field intensities with different magnitudes, and the Hall sensor 140 detects the magnetic field intensity which can be formed by the magnetic pieces 130 on the filter piece 120 after the installation is completed, so that the type of the filter piece 120 is judged.

In other embodiments, as shown in fig. 1-3, a plurality of magnetic members 130 are spaced apart along the path of movement of the filter element 120 during installation in the body 110, and at least one magnetic member 130 has a polarity opposite to the polarity of the other magnetic member 130. As in the present embodiment, when the filter 120 is mounted on the body 110, the depth direction of the dust storage space 124 in the filter 120 coincides with the height direction of the body 110, and at this time, the plurality of magnetic members 130 are disposed at intervals in the depth direction of the dust storage space 124 of the filter 120. For different types of filter elements 120, by changing the magnetic pole direction of one or more of the magnets mounted on the different types of filter elements 120, the magnetic field intensity detected by the hall sensor 140 can show different change trends in the process of mounting the filter element 120 on the body 110, so as to further judge the type of the filter element 120 mounted on the body 110.

Further, the cleaning apparatus 100 further includes an alarm module (not shown in the drawings, hereinafter, the same) in signal connection with the control module, and the alarm module is used for indicating the installation state of the filter 120 on the body 110. If the hall sensor 140 detects that the magnetic field intensity is not within the preset range, the control module calculates and analyzes the magnetic field intensity and then controls the alarm module to act, and the alarm module can feed back to the user in the form of sound, light and the like, so that the user can check whether the filter 120 is in place or not in time, and the like, so that the cleaning device 100 can work normally.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples only represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the claims. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application. Accordingly, the scope of protection of the present application is to be determined by the claims appended hereto.
