It is not necessary for individual components to be individually connected to the body, but rather for mechanical fixing to take place via the carrier and in particular solely via the carrier.All the components of the filter cleaning device are arranged on the carrier, so that no further steps are required (apart from electrical connection if appropriate).In this way, prefabricated filter-cleaning device modules can be installed on suckers (on the body of the suckers) in a simple manner.Moreover, repair or replacement is also possible in a simple manner, since no individual components have to be detached, but rather the filter-cleaning device as a whole can be removed from the body via the filter-cleaning device module.In particular, it is favorable if the at least one filter-cleaning device module is seated on the body in an exchangeable manner, wherein the carrier is connected to the body via a detachable fixing device. As a result, the filter cleaning device can be removed as a whole (as a module) and then repaired separately or replacement is possible in a simple manner. As a result, the overall service life of the suction device can be increased. The solution of the filter-cleaning device module is usually not provided for an operator, but for experts.In one embodiment, the fixing device is a (releasable) screw connection device. The carrier is fixed to the body by releasable screws. As a result, installation of the filter cleaning device as a unit via the module can be realized in a simple manner on the suction device and also removal can be carried out in a simple manner.It is advantageous if at least one of the following is provided:the carrier forms a mechanical interface, via which the at least one filter-cleaning device module is fixed to the body and is in particular exclusively fixed;the support forms a mounting base for components of the filter-cleaning device, which holds these components directly or indirectly on the body;the carrier forms a counter-contact region for a closing body;the carrier forms an openable and closable connection between a normal pressure region and a reduced pressure region for the controlled provision of a flushing air stream for cleaning the at least one filter;the carrier is plate-shaped and forms in particular a base plate of the at least one filter cleaning device module;- With respect to a height direction, the at least one filter cleaning device module has a first end and an opposite second end, wherein the second end faces the at least one filter, and wherein the carrier is positioned between the first end and the second end and is arranged in particular at a distance from the first end and / or at a distance from the second end.The carrier is, to a certain extent, a multifunction element of the filter-cleaning device module.The carrier forms the mechanical interface via which the at least one filter-cleaning device module is fixed to the body and is in particular exclusively fixed, that is to say no further mechanical connection is necessary between the filter-cleaning device module and the body outside the carrier.The carrier itself forms a mounting base for components and in particular all components of the filter cleaning device, and these components of the filter cleaning device are positioned on the body by the carrier. The carrier holds these components of the filter-cleaning device directly or indirectly (via intermediate elements which are seated on the carrier).The carrier itself advantageously also has a function with respect to generating a cleaning stream and in particular forms a counter-contact region for a closing body.Furthermore, the carrier can advantageously form a functional component for a cleaning stream by providing an openable and closable connection (having an openable and closable opening) between a normal pressure region and a reduced pressure region on the body for controlled provision of a flushing air stream for cleaning the at least one filter. In principle, it is favorable if the carrier separates a normal pressure range from a reduced pressure range in an embodiment with at least one valve in a closed position of the valve. For a cleaning process, this separation is canceled by the openable and closable connection and a corresponding flushing air stream can be provided for cleaning the at least one filter.In a structurally simple embodiment, the carrier is plate-shaped and forms in particular a base plate. This results in a compact construction. This results in a space-saving structure of the filter-cleaning device module and thus in turn an optimized "accommodation" on the body of the teat.The arrangement of the carrier between the first end and the second end results in a compact construction. The support can be assigned a plurality of functions (purely mechanical functions and also functions for carrying out a filter cleaning process, as described above).It is advantageous if the carrier separates a normal pressure range from a reduced pressure range on the body. The carrier can then itself form a partition wall between the normal pressure region and the reduced pressure region, wherein an openable and closable connection between the normal pressure region and the reduced pressure region can be provided via an opening of the carrier. As a result, a flushing air stream for acting on the at least one filter for cleaning it can be provided in a simple manner. This also results in a simplified structure of the suction device and in particular of its body. The filter-cleaning device module then also contains the partition wall in order to separate the normal pressure region from the low pressure region on the body. This in turn results in simplified assembly and a space-saving structure. The body of the teat can be produced in a simple manner.In one exemplary embodiment, the filter cleaning device generates a cleaning stream during operation, which acts on the at least one filter, wherein the filter cleaning device has at least one valve with a movable closing body and an opposing direction for the closing body, and wherein the at least one filter is acted on by a cleaning stream in an open position of the at least one valve and the cleaning stream is or becomes inactive in a closed position of the at least one filter, wherein the at least one valve is seated on the filter cleaning device module. In this embodiment, the filter cleaning is effected by subjecting the at least one filter to the cleaning stream. The cleaning stream can have a flushing effect when flowing through the filter in order to remove adhering dust particles. Additionally or alternatively, it can have a mechanical vibrating function in order to remove mechanically adhering dust particles in this way. The movable closing body allows the filter cleaning to be controlled and it can be initiated in a targeted manner. This initiation can be carried out, for example, manually by an operator, or it can be carried out according to specific specifications such as a time control or else according to requirements.It is very particularly advantageous if the carrier has an opening in which the closing body is movably positioned. In addition to acting as a mechanical connector to the body, the carrier then also has a function of generating and / or activating a purge stream. By means of the opening, it is possible, for example, to connect a normal pressure region in a controlled manner to a reduced pressure region in order to correspondingly generate the cleaning stream. Furthermore, the carrier can also be used as part of the counter device by providing the opening. This in turn allows the number of components for the filter-cleaning device module and also for the body to be reduced. This results in a simplified structure of the filter-cleaning device module and a simplified fixability of the filter-cleaning device module to the body.It is very particularly advantageous if the at least one filter-cleaning device module has all the functional components required for generating the cleaning stream. This results in simple assembly and releasability from the body.In one exemplary embodiment, it is provided that the counter device (as a functional component of the filter cleaning device) is seated on the carrier.It is furthermore advantageous if the at least one filter-cleaning device module comprises the following:a magnetic device;a spring device whose spring force tends to bring the at least one valve from the open position into the closed position.Corresponding essential functional components of the filter-cleaning device are then integrated into the filter-cleaning device module.The spring device is in particular a reset spring device which ensures a reset force on the closing body.In one exemplary embodiment, the magnetic device has a switchable lifting magnet and an armature is connected to the closing body, wherein the closing body can be driven in its movement via a coupling of the armature to the lifting magnet. This makes it possible to achieve a controlled valve opening in a simple manner by switching, in particular, the lifting magnet. In this case, it is provided in particular that, in a closed position of the at least one valve, the lifting magnet is not subjected to current and, in order to produce the open position of the valve, the lifting magnet is subjected to current.In an alternative embodiment, the magnet device comprises a switchable holding magnet and a counter element for the holding magnet is connected to the closing body. In this embodiment, current application to the holding magnet is necessary in order to hold the closed position of the at least one valve.It is furthermore advantageous if the at least one filter-cleaning device module comprises at least one of the following:a manual operating element which is connected to the closing body and serves for manually operating a cleaning operation;an elastic energy storage device which is associated with the at least one valve and / or an actuating element;at least one media communication interface.By means of a manual actuating element, an opening of the at least one valve can be achieved directly by an operator. In principle, however, it is also possible for a switch for manually triggering a filter cleaning process to be coupled to a control device which then provides corresponding commands to the filter cleaning device.By means of an elastic energy storage device, as is described in particular in EP 2 451 332 B2, a rapid opening of the at least one valve can be achieved.In one exemplary embodiment, the at least one filter-cleaning device module has a cap which is designed in particular in the form of a dome. This provides a type of top cover to cover corresponding elements of the filter cleaner. The cap can also be used for arranging or guiding movable elements of the filter cleaning device.In one exemplary embodiment, a movement space for an anchor is arranged on the cap. This results in a space-saving structure of the filter-cleaning device module.It is furthermore favorable if a holder for the magnet device and a guide device for the movable closing body are arranged on the carrier, wherein in particular the holder for the magnet device is designed as a guide device for the movable closing body. This results in a compact construction. The filter-cleaning device module then contains all the components necessary for the mode of operation.In particular, the holder for the magnetic device and / or the guide device for the movable closing body is directed towards a first end of the filter cleaning device module, which is remote from a second end, wherein the second end faces the at least one filter. This results in a compact construction. In particular, the filter-cleaning device module can then be arranged in such a way that one part is positioned in a normal pressure region and another part is positioned in a reduced pressure region.Furthermore, it is favorable to integrate all the components necessary for the function of the filter-cleaning device in the filter-cleaning device module if at least one receptacle for at least one spring of a spring device is arranged on the carrier. In particular, the spring device is designed as a reset spring device or comprises such a reset function.Advantageously, the at least one receptacle is positioned between a second end of the filter cleaning device module and the carrier, wherein the second end faces the at least one filter. This results in a compact, space-saving construction of the filter-cleaning device module.In a structurally favorable embodiment, a plurality of posts are arranged on the carrier, which posts are spaced apart from one another. Due to the spacing of the posts, in particular a media access (air access) for example to a closing body of the filter cleaning device is achieved. As a result, a type of media guide (air guide) can be integrated into the filter-cleaning device module. In this way, in particular, a corresponding pressurization of a closing body of the filter cleaning device can be carried out in a controlled manner. Furthermore, a cleaning stream can be supplied to the at least one filter in a targeted manner.It is then advantageous if at least one of the following is provided:supporting posts support a holder for a magnetic device;supporting posts hold a guide device for a movable closing body;posts hold at least a part of a counter device to a movable closing body;Posts hold a receptacle for a spring device.This results in a compact construction. Pressurization regions can be integrated into the filter-cleaner module.It is advantageous if spoke elements are arranged on a post, which support the receptacle for the spring device and in particular support it centrally with respect to a height direction of the filter-cleaning device module. In this way, in particular a cleaning stream can be provided, which can act on the at least one filter between the spoke elements.In an embodiment, posts extend from the carrier toward a first end of the filter washer module, the first end facing away from a second end of the filter washer module, and the second end facing the at least one filter. In this way, in particular a region can be realized which is then positioned in a normal pressure region of the body.It is furthermore advantageous if posts extend from the carrier towards a second end of the filter-cleaning device module, wherein the second end faces the at least one filter. As a result, a region of the filter-cleaning device module can be realized which is positioned on the body in a reduced pressure region.In a structurally simple embodiment, posts which extend toward the first end and posts which extend toward the second end are aligned and in particular each formed by a single element. Such posts can also be coupled to one another in principle by a connecting element such as a screw which engages on both types of posts.In one exemplary embodiment, it is provided that the closing body has at least one first contact region on the counter device and one second contact region on the counter device, wherein the second contact region is spaced apart from the first contact region in a height direction, that in the closed position of the at least one valve both the first contact region and the second contact region contact the counter device, and that in the open position of the at least one valve both the first contact region and the second contact region are spaced apart from the counter device, wherein in the open position of the at least one valve a flushing air stream flows past the filter both on the first contact region and on the second contact region.The corresponding design of a filter cleaning device is disclosed in particular in DE 10 2019 117 120 A1, to which express reference is made. Such a configuration enables a rapid opening of the at least one valve. A high level for a flushing air quantity results relatively quickly.In one embodiment, it is provided that (in addition to the filter cleaning device) also the blower device is seated on the body.It can furthermore be provided that the at least one filter is arranged on the body.In an advantageous embodiment, the body is a suction head which is positioned in particular removably on the suction material container. This results in a compact construction. In particular, all "electrical" components of the suction device can be integrated into the suction head.In one embodiment, the suction device is designed as a stand-alone vacuum cleaner, in particular having at least one of the following:the suction device is wearable by an operator;the suction device has rollers for travel;at least one carrying handle is arranged on the body;on the body or on a suction material container, with which the body can be detachably fixed, a suction connection for a suction hose is arranged.The vacuum cleaner may be a dry vacuum cleaner or a wet-dry vacuum cleaner.In particular, the at least one filter-cleaning device module is positioned between the at least one filter and an upper side of the suction device. This results in space-saving accommodation.For the same reason, it is favorable if the carrier is fixed to the body between an upper side of the teat and the at least one filter on the body.The following description of preferred embodiments serves to explain the invention in more detail in conjunction with the drawings.

In this context, reference is made by way of example to WO 2015 / 139751 A1, which describes an exemplary embodiment of a filter cleaning according to requirements.Alternatively or additionally, it is possible that a filter cleaning by the filter cleaning device 86 can be initiated manually by an operator directly or by corresponding control via the control device 88.With respect to the height direction 48, the filter cleaning device 86 is positioned above the filter 76 in the suction head 46 in order to enable direct application of a cleaning stream (air stream), in particular.The filter cleaning device 86 is thereby also arranged in the region of the rear end 32.In one embodiment (see FIG. 4 ), the filter 76 and the filter cleaning device 86 are positioned above the rear wheel device 22 with respect to the height direction 48. A line of projection of the filter cleaning device 86 and the filter 76 parallel to the height direction 48 is located at a support portion 90 at which the rear wheel device 22 is supported on a base (such as a floor surface) when it is correctly set on this base.In the suction head 46 (in the body 50), a receptacle 92 for the filter cleaning device 86 is arranged. This receptacle 92 is open toward one side and, in particular, open toward the filter 76 on the side 94. The filter cleaning device 86 can be inserted into the receptacle 92 via this side 94 and fixed to the suction head 46.The receptacle 92 has a system region 96, on which a carrier 98 of the filter cleaning device 86 can be placed and can be fixed in particular by screwing.The carrier 98 can be brought into the receptacle 92 via the side 94 and placed against the contact element 96 and then fixed in the receptacle 92, in particular by screwing to the contact region 96.The filter holder 82 with the filter 96 is positioned in the receptacle 92 (and in particular positioned removably) or is positioned on an imaginary extension of the receptacle 92 parallel to the height direction 48 toward the base 14.The filter cleaning device 86 is designed as a module 100 (filter cleaning device module 100) (compare FIGS. 5 to 7 ). This module 100 contains all the essential components for the filter cleaning function of the filter cleaning device 86. the module 100 is a unit which can be mounted as a unit in the suction head 46 and can be removed as a unit from the suction head 46. The module 100 comprises an electrical interface 102 for electrical connection to the control device 88 for a signal connection and for the electrical energy connection.The module 100 further comprises a first media communication interface 104, via which air is supplied with air from the environment of the suction head 46, and a second media communication interface 106 for providing the cleaning stream for supplying the filter 76.The module 100 comprises the carrier 98. the carrier 98 is in particular plate-shaped with an upper side 108 and an underside 110. When the module 100 is mounted in the suction head 46, the bottom 110 faces the filter 76. The top side 108 faces away from the bottom side 110.In particular, the top side 108 and the bottom side 110 are substantially parallel to each other and have the same distance from each other.The carrier 98 is provided with through-openings 112 in particular in the region of an outer periphery. By means of these, the carrier 98 can be fixed to the contact region 96 with releasable screws. As a result, the module 100 and thus in turn the filter cleaning device 86 as a whole can be mounted in the suction head 46 in a step (with the additional step of connection to the electrical interface 102) and can accordingly also be released from the suction head 46.The carrier 98 forms the mechanical interface of the module 100, via which the module 100 is fixed to the suction head 46, and thereby forms the sole fixing point. The carrier 98 is the base plate of the module 100 for mounting / fixing the module 100 to the suction head 46, and the carrier 98 is then in turn the carrier (holder) for the components of the filter cleaning device 86.The module 100 of the filter cleaning device 86 comprises at least one valve 114 (compare FIGS. 6 and 7 ) and in particular exactly one valve 114. The valve 114 is mounted on the support 98.The valve 114 has a closing body 116 which is movable relative to the carrier 98. A guide device 118 is seated on the carrier 98, on which the closing body 116 is movably guided and is guided, in particular, linearly movably.A movement axis 120 for the movement of the closing body 116 relative to the carrier 98 (and thus also relative to the suction head 46 when the module 100 is fixed to the suction head 46 ) is transverse and in particular perpendicular to the carrier 98 (transverse or perpendicular to the upper side 108 or the lower side 110).In one embodiment, in a module 100 mounted to the suction head 46, the axis of movement 120 is at least approximately parallel to the height direction 48.On the support 98, there is also a counter device 122 for the closing body 116.The valve 114 has a closed position 124 (FIG. 6 ) in which the closing body 116 bears against the counter device 122. In the closed position 124 of the valve 114, the valve 114 is inactive with respect to a purge stream for filter purge, i.e., no purge stream is provided to the filter 76.The valve 114 further includes an open position 126 (FIG. 7 ). In the open position 126, a purging current application to the filter 76 is provided.In one exemplary embodiment, the valve 114 is basically designed as described in DE 10 2019 117 920 A1. This document is expressly and fully incorporated by reference.The closing body 116 comprises a first disc 128 and a second disc 130 in one embodiment. The first pane 128 is spaced apart in height from the second pane 130 in a height direction parallel to the movement axis 120.A hub 132 is disposed between the first disc 128 and the second disc 130. In a direction parallel to the axis of movement 120, the first disc 128 and the second disc 130 each have a larger diameter than the hub 132.In cross section (compare FIG. 6 or 7 ), the closing body 116 has the shape of a thread roll or approximately the shape of a lying H, wherein the hub 132 corresponds to the bar of the H and the first disk 128 and the second disk 130 each correspond to a bar of the H.The first pane 128 is positioned above the top side 108 and the second pane 130 is positioned below the bottom side 110. The carrier 98 is thereby disposed between the first disc 128 and the second disc 130.The first disk 128 has a first contact region 134 for the counter device 122. The second disk 130 has a second contact region 136 for the counter device 122.The counter device 122 has a first counter-bearing region 138 for the first pane 128 and a second counter-bearing region 140 for the second pane 130.A shielding element 142 (mushroom element 142) is rigidly mounted on the support 98, which shielding element protrudes away from the upper side 108 toward a first end 144. The first end 144 is an end of the module 100 and faces the top 108 of the carrier 98.The module 100 has an opposing second end 146. This second end 146 faces the underside 110 of the carrier 98.A distance between the first end 144 and the second end 146 is at a height direction 148 of the module 100. This height direction 148 is parallel to the movement axis 120. It lies transversely and in particular perpendicularly to the carrier 98 or to its upper side 108 and / or lower side 110.The shielding element 142 is fixed to the carrier 98 via spaced posts 150 and in this case via a plurality of spaced posts 150. The posts 150 extend parallel to the height direction 148. As a result, the shielding element 142 is arranged such that its first counter-bearing region 138 is spaced apart from the upper side 108 of the carrier 98.The posts 150 are arranged in the region of an outer periphery of the carrier 98. With respect to a radial direction transversely to the height direction 148, the closing body 116 is arranged with its first disk 128 within the posts 150 and is thereby positioned below the shielding element 142 between the upper side 108 of the carrier 98 and the first counter-abutment region 138.A sealing device 152 is arranged on the first contact region 134 or alternatively on the first counter-contact region 138. When the first contact region 134 abuts against the first counter-contact region 138, the sealing device 152 ensures a corresponding fluid tightness.The second counter-bearing region 140 is formed by the underside 110 of the carrier 98.Seated on the second counter-bearing region 140 or the second disk 130 is a sealing device 154 for achieving a fluid-tightness in the closed position 124 of the valve 114.In the closed position 124 of the valve 114, the first contact region 134 of the closing body 116 bears against the first counter-contact region 138 of the shielding element 142. At the same time, the wide contact region 136 of the second pane 130 abuts the second counter-contact region 140 on the carrier 98. The sealing devices 152, 154 ensure the corresponding fluid tightness. Compare this with FIG. 6.The spaced posts 150 allow lateral air entry.A holder 156 for a magnetic device 158 is seated on the support 98. The magnet device 158 is held firmly (immovably) on the module 100 via the holder 156. The holder 156 is formed in particular via the shielding element 142 and the posts 150.The magnetic device 158 is fixedly positioned in the module 100 above the top side 108 and surrounded by the first counter-abutment region 138.In one exemplary embodiment, the magnet device 158 comprises an (electric) magnet 160. This is controlled by the control device 88 (when connected via the electrical interface 102). The magnet 160 is positioned in a rotationally fixed manner centrally and in particular coaxially with respect to an axis of symmetry of the valve 114 (which is parallel to the height direction 148). The magnet 160 is designed as a lifting magnet.The valve 114 includes a spindle 162. The spindle 162 is oriented parallel to the height direction 148 and lies centrally on the axis of symmetry of the valve 114. It is movable in the movement axis 120.The closing body 116 is connected to the spindle 162 in a movement-fixed manner and a movement of the spindle 162 along the movement axis 120 brings about a movement of the closing body 116 relative to the counter-abutment regions 138, 140.An anchor 164 is mounted on the spindle 162. The anchor 164 is positioned in particular in the region of the first end 144 of the module 100. The armature 164 cooperates with the magnet 160. The armature 164 is designed, for example, as an iron core. The armature 164 is connected in a movement-proof manner to the spindle 162.When the magnet 160 is energized (controlled via the control device 88), the magnet 160 of the magnet device 158 exerts a force on the armature 164 and thereby via the spindle 162 on the closing body 116. As a result of this force, the closing body 116 can lift off from the counter device 122 (the first counter-bearing region 138 can lift off from the first bearing region 134 and the second counter-bearing region 140 can lift off from the second bearing region 136). The valve 114 is thereby opened (compare FIG. 7 ). The valve 114 is then in the open position (in the open position 126).Also disposed on the bracket 98 are posts 166 that project from the bottom 110 to the second end 146 of the module 100. The posts 166 are spaced apart from each other. They are oriented parallel to the height direction 148.In one embodiment, posts 166 corresponding to posts 150 are provided, with corresponding posts 150 and 166 aligned. It is possible in principle for such corresponding posts 150, 166 to be formed by a single post.In one embodiment (see FIG. 6 ), a corresponding post pair with posts 150 and posts 166 is associated with a common mounting screw 168. This screw 168 passes through a post 150, penetrates the bracket 98, and is then connected to the corresponding post 166.Posts 166 support a receptacle 170 via spoke members 172. The spoke elements 172 are located in the region of the second end 146 of the module 100 and are spaced apart from the carrier 98.The receptacle 170 is arranged centrally and lies on the axis of symmetry.A spring 174 of a spring device 176 is supported on the receptacle 170. The spring 174 is coupled to the spindle 162 such that when transitioning from the closed position 124 to the open position 126, the spindle 162 acts on the spring 174 to compress (see FIG. 7 ).In one embodiment, this coupling is achieved by the second disc 130 having a corresponding support region 178 for the spring 174.The spring device 176 with the spring 174 is arranged and designed such that the spring 174 is compressed during the transition from the closed position 124 to the open position 126, and the spring force of said spring device then tends to bring the valve 114 from the open position 126 into the closed position 124.The spring device 176 is a restoring spring device and the spring 174 is a restoring spring for the closing body 116.In one exemplary embodiment, an elastic energy storage device 180 is arranged on the closing body 116, which in particular comprises a spring. The elastic energy storage device 180 serves to increase the opening speed of the valve 114. A force effect of an (energy storage) spring of the elastic energy storage device 180 tends to lift the closing body 116 from the counter device 122. Reference is made in this connection to EP 2 451 332 B1.The module 100 further includes a cap 182 in the region of the first end 144. Specifically, the cap 182 forms the first end 144 of the module 100.The cap 182 has an inner movement space 184 for the armature 164.The cap 182 is dome-shaped and positioned on the shield member 142. It is also positioned on the magnet 160 of the magnet device 158 and forms a type of top cover of the module 100.In the body 50 (in the suction head 46), a normal pressure region 186 and a negative pressure region 188 are formed during a suction operation of the suction device 10. The normal pressure region 186 is in fluid communication with an outer space of the suction device 10. This is indicated in FIGS. 6 and 7 by p 2.The vacuum region 188 is in fluid communication with the vacuum side of the blower device 74. the vacuum region 188 is in fluid communication with the dirt side 80 of the filter 74.The carrier 98 on the receptacle 92 is arranged in such a way that it separates the normal pressure region 186 from the low pressure region 188 and in particular (in the closed position 124 of the valve 114) separates it in a fluid-tight manner. The normal pressure region 186 lies above the upper side 108 of the carrier 98 with respect to the height direction 148, and the low pressure region 188 lies below the lower side 110 of the carrier 98 with respect to the height direction 148.The carrier 98 has a through opening 190 which (with the closing body 116 removed or with the valve 114 in the open position 126) lies between the normal pressure region 186 and the low pressure region 188 and fluidically connects these to one another. The opening 190 is arranged in particular centrally on the carrier 98 and lies on the axis of symmetry of the module 100.The hub 132 of the closing body 116 is positioned in the opening 190 and is movable in the opening 190 due to the mobility of the closing body 116 in the movement axis 120. The second disc 130 has a larger diameter than the opening 190 to enable fluid-tight engagement of the second abutment portion 136 with the second counter abutment portion 140.In one embodiment, the first disc 128 also has a larger diameter than the aperture 190.In the closed position 124 of the closing body 116, the second pane 130 of the closing body 116 abuts with its second abutment region 136 against the second counter-abutment region 140 of the carrier 98. As a result, the opening 190 is closed in a fluid-tight manner. As a result, the normal pressure region 186 is in turn separated from the low pressure region 188 in a fluid-tight manner.The pressure p 2 in the normal pressure region 186 is greater than the pressure p 1 in the reduced pressure region 188 (in a suction mode of the suction device 10).In the exemplary embodiment of the module 10, in the closed position 124, sealing of the first bearing region 134 on the first counter-bearing region 138 is also achieved. There is therefore a seal on at least two planes which are spaced apart in the height direction 148. In this connection, reference is made to DE 10 2019 117 920 A1, to which express reference is made.The spaced posts 150 form the first media communication interface 104, which allows normal pressurization of the first disk 128 and the second disk 130 (after lifting from the carrier 98).The posts 166 and the spaced apart spoke elements 172 also achieve a vacuum coupling of the module 100 in the suction head 46, so that the second disk 130 is subjected to a vacuum in the vacuum region 188.Furthermore, the second media communication interface 106 is provided by the spoke elements 172 and the posts 166, via which a cleaning stream (flushing air stream) can then act on the filter 76 to be cleaned.The filter cleaning device 86 installed in the suction device 10 and in the process in the suction head 46 functions as follows:In a suction mode of the suction device 10, the blower device 74 generates a suction flow. As a result, a reduced pressure is present in the reduced pressure region 188 with respect to the normal pressure region 186 (p 2 >p 1).In a non-purge mode, the valve 114 is closed, i.e., in the closed position 124 (FIG. 6 ). The first contact region 134 bears against the first counter-contact region 138 and the second contact region 136 bears against the second counter-contact region 140.Upon initiation of a filter cleaning operation, the closure body 116 is moved. As mentioned above, the initiation can be triggered by an operator (manually triggered) or it can be triggered according to a specification, such as, for example, according to requirements or after specific time intervals and in particular operating time intervals.The movement of the closing body 116 is achieved in that the magnet 160 is energized under the control of the control device 88. This results in movement of the armature 164 and results in lifting of the closing body 116 from the counter device 122; the first disc 128 lifts from the shielding element 142 and, synchronously therewith (due to the connection to the hub 132), the second disc 130 lifts from the carrier 98.As a result, flow channels between the first contact region 134 and the first counter-contact region 138 and between the second contact region 136 and the second counter-contact region 140 are opened on the module 100. With respect to an air flow, the opening at the first contact region 134 / first counter-contact region 138 corresponds to an opening on the input side and the opening at the second contact region 136 / second counter-contact region 140 corresponds to an opening on the output side.Due to the pressure difference between the normal pressure region 186 and the low pressure region 188, air flows flow which are in particular annular when the valve 114 is formed with the disks 128, 130. A partial flow flows through the closing body 116 and a further partial flow flows around the closing body 116.A flushing stream then flows through the vacuum region 188 to the filter 76; a cleaning stream is produced which acts on the filter 76. Adhering dirt particles can separate from the filter 76 and fall into the suction material container 12.The filter 76 is flushed by the flushing stream. Furthermore, the corresponding cleaning stream generally also has a mechanical shaking effect, which likewise leads to the detachment of dirt particles from the filter 76.The filter cleaning is effected in such a way that the suction flow of the blower device 74 continues to be present at the vacuum region 188.The spring 174 provides the restoring force which, after the energization of the magnet 160 has ended, returns the closing body 116 with the first bearing region 134 bearing against the first counter bearing region 138 and the second bearing region 136 bearing against the second counter bearing region 140. The reduced pressure region 188 is then separated from the normal pressure region 186 in a fluid-tight manner again in the corresponding closed position 124.Cleaning is effected in particular in such a way that the magnet 160 is activated in a pulsed manner and a pulsed flushing current accordingly also acts on the filter 76. In this case, a pulsed opening and closing of the valve 114 takes place.In an alternative embodiment, a magnetic device is provided which uses a holding magnet, an associated magnetic holding plate being seated on the spindle. The holding magnet is energized in such a way that it exerts a magnetic force on the holding plate and thereby closes the closing body. To open the corresponding valve, the current application to the holding magnet is changed, so that the magnetic force of the holding magnet is no longer sufficient to hold the closing body with the holding plate in the closed position. Reference is made in this connection to DE 10 2019 117 920 A1.An embodiment of a filter cleaning device 86 with a valve 114 with contact areas on different levels has been described. In principle, the module 100 can also have a valve, as is described, for example, in DE 10 2010 029 524 A1.The filter cleaning device 86 is realized on the module 100. The module 100 has all the functional components of the filter cleaning device 86. The body 50 (the suction head 46) has with the receptacle 92 a receiving region for the module 100. When the suction head 46 is equipped with the filter cleaning device 86, no individual components of the filter cleaning device 86 have to be individually connected to the suction head 46 (to the body 50), but the module 100 is inserted as a whole (brought into the receptacle 92) and the mechanical connection is effected via the fixing of the carrier 98 to the contact region 96, only the electrical connection has to be produced at the electrical interface 102 in order to correspondingly electrically connect the control device 88 to the module 100.The carrier 98 has a multiple function. It forms the mechanical interface for mounting the module 100 and thus the entire filter cleaning device 86 on the suction head 46.The filter cleaning device 86 can be easily detached as a whole, in particular by removing corresponding screws, in order to repair or replace them. Such a solution is usually not provided for the operator, but for a repair operation or replacement operation.The support 98 also functions as a base plate which holds respective components of the filter cleaner 86. In particular, it holds posts 166 and 150 and thereby receptacle 170 and holder 156 for magnet device 158 and guide device 118.Furthermore, the carrier 98 is also a functional component for the functioning (for the cleaning function) of the filter cleaning device 86. the carrier 98 has the opening 190 in which the closing body 116 is positioned and which makes possible the fluidic connection with the normal pressure region 186 and the low pressure region 188 for the provision of a flushing air flow during a cleaning operation. Furthermore, the carrier 98 provides the second counter-abutment region 140 for the closing body 116.This modular construction allows the suction device 10 with the filter cleaning device 86 to be produced in a simple manner. Repair or replacement of the filter cleaning device 86 is possible in a simple manner. This results in a compact construction.The solution according to the invention with the module 100 can be used in particular in a dry vacuum cleaner or wet dry vacuum cleaner.The suction head 46 can be locked to the receptacle 12. In particular, the suction head 46 comprises an immersion region 192 (compare FIG. 3 ), which is immersed in the interior 18 of the suction material container 12 when the suction head 46 is placed on the suction material container 12. The immersion region 192 is adapted in particular in its contour to the contour of the absorbent container 12.Furthermore, locking elements 194 are provided, with which the suction head 46 can be locked to the receptacle 12. In particular, the combination of suction head 46 and suction material container 12 as a whole can be lifted up, for example, on the carrying handle 54 if the suction head 46 is locked to the suction material container 12 via the locking elements 194.In one embodiment, movable latches 196 are disposed on opposite sides of the suction head 46. On the wall 16 and in this case on the lateral sides 28, corresponding counter elements 198 for the bolts 196 are positioned.In particular, a latching connection can be achieved between a latch 196 and an associated counter element 198.In principle, it is also possible for a movable latch 196 to be arranged on the suction material container 12 and for a counter element 198 to be arranged on the suction head 46.List of reference characters10 Suction device 12 Suction material container 14 Floor 16 Wall 18 Interior 20 Wheel device 22 Rear wheel device 24 Right rear wheel 26 Left rear wheel 28 Lateral side 30 Front end 32 Rear end 34 Wheel axle 36 Front wheel device 38 First steering roller 40 Second steering roller 42 Bumper device 44 Receptacle 46 Suction head 48 Height direction 50 Body 52 Upper side 54 Carrying handle 56 Planar region 58 Front side 60 Suction connection 62 Connecting pieces 64 a, 64 bcontainer 66 battery 68 width direction 70 switch 72 operator panel 74 blower device 76 filter 78 clean side 80 dirt side 82 filter holder 84 underside 86 filter cleaning device 88 control device 90 support region 92 receiver 94 side 96 installation region 98 carrier 100 module 102 electrical interface 104 first media communication interface 106 second media communication interface 108 upper side 110 underside 112 opening 114 valve 116 closing body 118 guide device 120 movement axis 122 counter device 124 closed position 126 open position 128 first disk 130 second disk 132 hub 134 first installation region 136 second installation region 138 first counter installation region 140 second counter installation region 142 shielding element 144 first end 146 second end 148 height direction 150 post 152 sealing device 154 sealing device 156 holder 158 magnetic device 160 162 Magnet 162 Spindle 164 Armature 166 Post 168 Screw 170 Receptacle 172 Spoke element 174 Spring 176 Spring device 178 Supporting region 180 Elastic energy storage device 182 Cap 184 Movement space 186 Normal pressure region 188 Reduced pressure region 190 Opening 192 Insertion region 194 Locking element 196 Latch 198 Counter elementReferences included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
