Description

[0001] The invention relates to a plug connection for a vacuum cleaner comprising a plug-in connector and a plug-in sleeve, wherein a locking element is arranged on the plug-in sleeve, the locking element being movable between an unlocked position and a locked position, the plug-in sleeve having a clamping wedge, the clamping wedge being configured to engage with the plug-in connector in a locked position of the locking element and to pivot into a receiving space of the plug-in sleeve in an unlocked position of the locking element. The invention further relates to a vacuum cleaner with such a plug connection.

[0002] In the prior art, as described, for example, in EP 3 854 281 B1, plug connectors for vacuum cleaners are known. These connectors allow the connection and disconnection of various vacuum cleaner components via a locking element on the connector sleeve. The user manually moves this locking element between an unlocking and a locking position. A disadvantage of this design is that unlocking the connector always requires accessing the connector sleeve. In vacuum cleaner configurations using two such connectors, this necessitates that the user hold both the connector sleeve and the plug to disconnect the connection. This so-called two-handed operation of the connector is perceived by users as neither convenient nor intuitive.

[0003] The invention therefore addresses the problem of providing an improved plug connection and an improved vacuum cleaner. In particular, the operation of the plug connection should be as convenient as possible and perceived by the user as intuitive.

[0004] According to the invention, this problem is solved by a plug connection with the features of claim 1 and by a vacuum cleaner with the features of claim 11.

[0005] According to the invention, an actuating mechanism is arranged on the plug connector, wherein the actuating mechanism is movable between a first and a second position, and wherein the actuating mechanism is configured to move the locking element in the plug sleeve from the locked position to the unlocked position in a second position. The actuating mechanism moves the locking element from the locked position to the unlocked position when the plug connector is arranged in the plug sleeve and when the actuating mechanism is moved from the first position to the second position.

[0006] The socket of the connector can positively engage the plug. In the unlocked position of the locking element, the plug can be removed from the socket. In the locked position of the locking element, the plug is positively and / or force-fittedly locked in the socket. The locking element of the connector can be manually moved by the user between an unlocked and a locked position. The user can unlock or lock the connector independently of the actuating mechanism on the plug via the locking element. The receiving space of the socket is a free space designed to at least partially accommodate the clamping wedge in the unlocked position. The actuating mechanism is designed to be moved by the user between a first and second position.

[0007] The arrangement of an actuating mechanism on the plug connector allows the connection to be disconnected with one hand from the side of the plug connector. This means that the locking element on the plug sleeve can be unlocked using the actuating mechanism on the plug connector.

[0008] A vacuum cleaner according to the invention with such a plug connection can be a so-called "stick vacuum cleaner", a canister vacuum cleaner, or a handheld mop or vacuum mop designed for the manual wet cleaning of floor surfaces. A plug connection according to the invention can be arranged between the individual components of such a vacuum cleaner to detachably connect them to one another. In a particularly preferred embodiment, such a vacuum cleaner can also have several such plug connections according to the invention.

[0009] A vacuum cleaner with this type of connector is particularly easy to use, as the connector can be unlocked with just one hand via the connector. Furthermore, operating a vacuum cleaner with this type of connector is perceived as especially intuitive.

[0010] Advantageous embodiments and further developments of the invention are set forth in the dependent claims. It should be noted that the features listed individually in the claims can also be combined with one another in any technologically meaningful way, thus revealing further embodiments of the invention.

[0011] Preferably, the actuating mechanism is designed to transmit a compressive force to the locking element in the second position. The actuating mechanism exerts a compressive force on the locking element, which, as a result of this force, moves from the locked position to the unlocked position. The actuating mechanism on the plug socket thus enables reliable movement of the locking element on the plug socket from the locked position to the unlocked position.

[0012] Furthermore, it is preferred that the actuating mechanism comprises an actuating element, a lever element, and a plunger, wherein the lever element connects the actuating element and the plunger, and wherein the lever element transmits a movement of the actuating element to the plunger, the plunger being configured to transmit a compressive force to the locking element. The lever element is rotatably mounted on the plug socket. In a preferred embodiment, the lever element has two lever arms. In a particularly preferred embodiment, the two lever arms have different lengths. Alternatively, it is also conceivable to provide lever arms of identical length. The plunger can be configured to push the plug socket and the plug sleeve away from each other by transmitting the compressive force to the locking element.

[0013] The lever element reduces the force required to unlock the connector via the actuating mechanism. The plunger reliably unlocks the connector. Furthermore, the plunger can be used to separate the plug and socket.

[0014] Preferably, the actuating mechanism comprises a gear, a first rack, and a second rack, wherein movement of the first rack is transmitted via the gear to the second rack, the second rack being configured to transmit a compressive force to the locking element. The first and second racks are engaged with the gear. The direction of movement of the first rack can be opposite to the direction of movement of the second rack. In an alternative embodiment, several gears can be arranged in the actuating mechanism.

[0015] Using a gear drive reduces the required installation space for the actuating mechanism. Furthermore, using a gear drive reduces the force the user must apply to unlock the connector on the actuating mechanism.

[0016] It is further preferred that the locking element has a contact surface for receiving a compressive force from the actuating mechanism, wherein the locking element is moved from the locked position to an unlocked position by receiving a compressive force. The contact surface of the locking element is designed such that it can reliably receive the compressive force of the actuating mechanism and transfer it completely to the locking element. For this purpose, the contact surface of the locking element is designed to be as large and stable as possible.

[0017] The contact surface of the locking element enables a safe introduction and transmission of force from the actuating mechanism to the locking element.

[0018] Preferably, the locking element has a first magnetic element, wherein the actuating mechanism has a second magnetic element for exerting a magnetic holding force on the first magnetic element in the first position of the actuating mechanism.

[0019] The first magnetic element on the locking element and the second magnetic element on the actuating mechanism secure the locking element in a locked position when the actuating mechanism is in the first position. The first and second magnetic elements are designed such that a magnetic attraction exists between them. When the second magnetic element of the actuating mechanism moves to the second position, the locking element moves from a locked position to an unlocked position. In a preferred embodiment, the locking element is moved from the locked position to the unlocked position by an applied spring force when the second magnetic element is not exerting a holding force on the first magnetic element.The applied spring force is less than the holding force between the first and second magnetic elements when the actuating mechanism is in the first position. The applied spring force is greater than the holding force between the first and second magnetic elements when the actuating mechanism is in the second position.

[0020] Furthermore, it is preferred that the actuating mechanism includes a retaining element with the second magnetic element, wherein the retaining element is movably designed. The retaining element is configured to receive and fix the magnetic element. In the first position of the actuating mechanism, the second magnetic retaining element exerts a magnetic attraction on the first magnetic element, thereby holding the locking element in the locked position. In the second position of the actuating mechanism, the second magnetic retaining element exerts only a weak magnetic attraction on the first magnetic element, thereby moving the locking element from the locked position to the unlocked position.

[0021] It is further preferred that the actuating mechanism comprises a transmission element with an elongated hole and the holding element with the second magnetic element, wherein the holding element has a cam, the cam being arranged in the elongated hole of the holding element. The cam of the holding element is guided in the elongated hole of the transmission element. Consequently, a movement of the transmission element from a first position to a second position is transmitted to the holding element via the elongated hole and the cam.

[0022] Fixing the locking element in a locking position by means of magnetic holding force represents a particularly reliable alternative for the realization of the plug connection according to the invention.

[0023] Furthermore, it is preferred that the actuating mechanism includes an actuating element, in particular a sliding element or a sleeve. The actuating element is designed to be actuated by the user of the connector. A sliding element or a sleeve can be actuated by a user in a simple and intuitive manner.

[0024] It is preferred that the locking element is designed as a cap or sleeve. In a particularly preferred embodiment, both the locking element and the actuating element are designed as sleeves. This allows for simple and intuitive unlocking of the plug connection at the plug sleeve and the plug socket.

[0025] In a preferred embodiment, the vacuum cleaner comprises a housing, a suction tube, and a handle, wherein the plug connection is designed to connect the housing to the handle and / or to the suction tube. The plug sleeve of the connection is located on the housing. The plug sleeve of the connection is designed to positively engage a plug fitting on the suction tube or handle.

[0026] The vacuum cleaner housing includes a fan for generating a suction airflow, a separator for removing dust and dirt particles from the exhaust airflow, and a dust storage unit for storing the collected dust and dirt particles. The housing may also include an energy storage unit, in particular a battery. The separator is preferably a cyclone separator.

[0027] Preferably, the vacuum cleaner comprises a suction tube, a housing, and a handle, wherein the plug connection is designed to connect the suction tube to the handle and / or to the housing. The plug sleeve of the connection is located on the suction tube. The plug sleeve of the connection is designed to engage a plug fitting on the housing or handle in a form-fitting manner.

[0028] Furthermore, it is preferred that the vacuum cleaner comprises a nozzle, a suction tube, and a housing, wherein the plug connection is designed to connect the nozzle to the housing and / or to the suction tube. The plug socket of the connection is located on the nozzle. The plug socket of the connection is designed to receive a plug fitting on the housing or suction tube in a form-fitting manner. The nozzle can be a nozzle for vacuuming a floor surface. In an alternative embodiment, however, the nozzle can also be a nozzle for wet cleaning a floor surface, for example, for mopping or vacuum mopping.

[0029] In a particularly preferred embodiment of the vacuum cleaner according to the invention, it has three plug connections. A vacuum cleaner according to this embodiment has a first plug connection with a plug socket on the housing for connection to the handle element or the suction tube. In addition, the vacuum cleaner has a second plug connection with a plug socket on the suction tube for connection to the housing or handle element. Furthermore, the vacuum cleaner has a third plug connection with a plug socket on the nozzle for connection to the suction tube or the housing.

[0030] A vacuum cleaner with a plug-in connection according to the invention allows for the flexible assembly of various vacuum cleaner components into different vacuum cleaner architectures. This enables the user to independently adapt the vacuum cleaner to different cleaning scenarios.

[0031] Preferably, an actuating mechanism is arranged on the handle, the suction tube, and / or the housing. The actuating mechanism is designed to move the locking element in a socket from the locked position to an unlocked position when the corresponding plug of the actuating mechanism is inserted into the socket. In a particularly preferred embodiment of the vacuum cleaner according to the invention, it has an actuating mechanism on the handle, the housing, and the suction tube.

[0032] Further features, details, and advantages of the invention will become apparent from the following description and the drawings. Exemplary embodiments of the invention are shown purely schematically in the following drawings and are described in more detail below. Corresponding objects or elements are designated with the same reference numerals in all figures.

[0033] The representation according to Fig. Figure 1 shows a vacuum cleaner 12 with a handle element 64, a housing 60, a suction tube 62, and a nozzle 66 in three different assembly configurations. The vacuum cleaner 12 has several plug-in connections 10, which enable the user to assemble the vacuum cleaner 12 in these configurations.

[0034] The vacuum cleaner 12 has a handle 64 by means of which the vacuum cleaner 12 can be held and moved. Display and control elements can be arranged on the handle 64, enabling control and monitoring of the vacuum cleaner 12's functions during cleaning operation. The vacuum cleaner 12 also has a housing 60 in which the blower (not shown) for generating a suction airflow, the separator 68 for separating dust and dirt particles from the suction airflow, a storage unit 70 for storing separated dust and dirt particles, and an energy storage unit (not shown) are arranged. The vacuum cleaner 12 also has a suction tube 62 for guiding the suction airflow and a nozzle 66 for contacting the surface to be cleaned.

[0035] In the first configuration of the vacuum cleaner 12, the handle 64 is connected to the housing 60, and the housing is connected to the nozzle 66 via the suction tube 62. This configuration is particularly suitable for cleaning under furniture such as tables or sofas. In the second configuration, the handle 64 is connected to the suction tube 62, the suction tube to the housing 60, and the housing to the nozzle 66. This configuration is particularly suitable for cleaning larger areas. In the third configuration, only the handle 64 is connected to the housing 60. This configuration is suitable for spot cleaning of higher areas such as tables or ceilings.

[0036] To implement the various assembly configurations, the vacuum cleaner 12 has three connectors 10, each consisting of a socket 16 and a connector 14. The socket 16 of the first connector 10 is located on the housing 60. This socket 16 allows the housing 60 to be connected to the connector 14 of the handle 64 or the suction tube 62. The socket 16 of the second connector 10 is located on the suction tube 62. This socket 16 allows the suction tube 62 to be connected to the connector 14 of the housing 60 or the handle 64. The socket 16 of the third connector 10 is located on the nozzle 66. This socket 16 allows the nozzle 66 to be connected to the connector 14 of the housing 60 or the suction tube 62.

[0037] An actuating mechanism 28 is arranged at the plug connector 14 of the handle element 64, the housing 60 and the suction pipe 62. This enables the locking element 18 to move in a corresponding plug sleeve 16 into an unlocking position 20.

[0038] The representation according to Fig. Figure 2 shows a close-up view of a handle element 64 of the vacuum cleaner 12. A plug connector 14 of the plug connection 10 is arranged on the handle element 64. Next to the plug connector 14 is a plunger 38 of the actuating mechanism 28, which is designed to move a locking element 18 in a corresponding plug sleeve 16 from a locking position 22 to an unlocking position 20. Next to a grip section of the handle element 64 is an actuating element 34 of the actuating mechanism 28. The actuating element 34 is designed as a sliding element. The sliding element can be actuated by a user. By actuating the sliding element, the actuating mechanism 28 is moved to the second position, whereby the plunger 38 moves the locking element 18 in a corresponding plug sleeve 16 to an unlocking position 20.

[0039] Fig. Figure 3 shows a close-up view of the suction tube 62 of the vacuum cleaner 12. The suction tube 62 has a socket 16 at one end and a connector 14 at the opposite end. A locking element 18 in the form of a cuff is arranged on both the connector 14 and the socket 16. The cuff can be moved by a user along the suction tube 62 between an unlocking and a locking position 20, 22. The cuff is spring-loaded in the direction of the locking position 22.

[0040] Fig. Figure 4 shows a sectional view through a plug connection 10 according to the invention with a locking element 18 in a locking position 22. The plug connector 14 is fully inserted into the corresponding plug sleeve 16. A locking element 18 in the form of a sleeve is arranged on the plug sleeve 16, which is in a locking position 22. In this locking position 22, the sleeve presses a movable clamping wedge 24 in the plug sleeve 16 against a chamfer of the plug connector 14. This locks the plug connector 14 with the clamping wedge 24 in the plug sleeve 16.

[0041] Fig. Figure 5 shows a sectional view through a plug connection 10 according to the invention with a locking element 18 in an unlocked position 20. The plug connector 14 is fully inserted into the corresponding plug sleeve 16. The sleeve, which functions as the locking element 18, is in the unlocked position 20. In this position, the sleeve does not press the clamping wedge 24 into a chamfer of the plug connector 14. As a result, the clamping wedge 24 moves into a receiving chamber 26 of the plug sleeve 16 and is no longer engaged with the plug connector 14. Consequently, the plug connector 14 can be removed from the plug sleeve 16.

[0042] Fig. Figure 6 shows a sectional view through a handle element 64, which is connected to a suction pipe 62 by means of a plug connection 10. The plug 14 of the handle element 64 is fully inserted into the plug sleeve 16 of the suction pipe. A sleeve with a locking element 18 is arranged on the plug sleeve 16 of the suction pipe 62, the locking element 18 being in a locking position 22. In this locking position 22, the clamping wedge 24 of the plug sleeve 16 is pressed by the locking element 18 against a chamfer of the plug 14.

[0043] The handle element 64 has an actuating mechanism 28 for moving the locking element 18 from a locked position 22 to an unlocked position 20. For this purpose, the actuating mechanism 28 has an actuating element 34, which is connected to a plunger 38 via a lever element 36. The lever element 36 is rotatably mounted in the handle element 64 and is designed to transmit a movement of the actuating element 34 to the plunger 38. The plunger 38 is in direct engagement with the contact surface 46 of the locking element 18. The plug connection 10 shown can be unlocked by moving the sleeve or by actuating the actuating element 34.

[0044] Fig. Figure 7 shows a sectional view through a handle element 64 according to Fig. 6 with a locking element 18 in unlocking position 20. To unlock the plug connection 10, the actuating element 34 on the handle element 64 was moved to the second position 32. The movement of the actuating element 34 was transmitted via the lever element 36 to the plunger 38, which is engaged with the contact surface 46 of the locking element 18. As a result of the movement of the plunger 38, the locking element 18 was moved from a locked position 22 to an unlocked position 20 against an applied spring force. The sleeve on the intake manifold 62 was also moved to the unlocked position 20 as a result.

[0045] Fig. Figure 8 shows a sectional view through a handle element 64 with a further embodiment of an actuating mechanism 28. This actuating mechanism 28 also has an actuating element 34, which can be moved by the user between a first position 30 and a second position 32. The actuating element 34 is connected to a transmission element 54, which has an elongated slot 56. The cam 58 is arranged in this elongated slot 56 and is connected to a retaining element 52. A movement of the transmission element 54 is transmitted to the retaining element 52 via the cam 58 located in the elongated slot 56. A second magnetic element 50 is arranged on the retaining element 52, which, in a first position 30 of the actuating mechanism 28, exerts a magnetic holding force on a first magnetic element 48 on the locking element 18 of the plug connector 14.This causes the locking element 18 to be held in the plug socket 14 in the locking position 22 due to the magnetic attraction between the first and second magnetic elements 48, 50. The locking element 18 is held in the locking position 22 by the applied magnetic force against a spring force acting on the locking element 18.

[0046] Fig. Figure 9 shows a sectional view through a handle element 64 with an identical actuating mechanism 28 and a locking element 18 in an unlocked position 20. The movement of the actuating element 34 causes the transmission element 54, via the cam 58 in the elongated hole, to move the retaining element 52 into a second position 32. This moves the second magnetic element 50 away from the first magnetic element 48, so that the magnetic force acting between the two elements 48 and 50 is less than the spring force acting on the locking element 18. Consequently, the spring force moves the locking element 18 from a locked position 22 into an unlocked position 20.

[0047] Fig. Figure 10 shows an intake manifold 62 with a plug connector 14 of a plug connection 10. An actuating mechanism 28 is arranged on the plug connector 14, comprising a sleeve, a lever element 36, and a plunger 38. The sleeve 34 is movably mounted on the intake manifold 62 and can be moved between a first position 30 and a second position 32. The sleeve 34 is positively connected to the lever element 36. When the sleeve 34 is moved from the first position 30 to the second position 32 in an unlocking direction 72, this movement is transmitted to the lever element 36. Subsequently, the lever element 36 transmits this movement to a plunger 38, which is connected to the lever element 36. The plunger 38 is connected to the side of the lever element 36 that is opposite the side of the lever element 36 to which the sleeve is connected. The plunger 38 is designed to exert a pressure force on a plug sleeve 16 (not shown in Fig. 10) to exert force on a plug connection 10. The sleeve of the plug connector 14 is spring-loaded in a locking direction 74. The locking direction 74 is opposite to the unlocking direction 72.

[0048] Fig. Figure 11 also shows a suction pipe 62 with a plug fitting 14 of a plug connection 10. In Fig. In position 11, the cuff 34 is displaced into the second position 32. As a result, the cuff 34 deflects the lever element 36, causing the lever element 36 to move the plunger 38 in the opposite direction of movement of the cuff 34 towards the socket 16 (not shown in Figure 11). Fig. 11) pushes.

[0049] Fig. Figure 12 shows an alternative embodiment of the actuating mechanism 28. In this embodiment, the actuating mechanism 28 has a first and second rack 42, 44, which are movably connected to each other via a gear 40. The first rack 42 is connected to the sleeve 34 on the intake manifold 62. By moving the sleeve from a first position 30 to a second position 32, the gear 40 is rotated by the first rack 42. The gear 40 transmits this rotational movement to the second rack 44, which bears against the contact surface 46 of the locking element 18 of the plug sleeve 16. The locking element 18 of the plug sleeve 16 is located in Fig. 12 in the locking position 22, in which the plug sleeve 16 locks the plug connector 14 via the clamping wedge 24.

[0050] Fig.Figure 13 shows an actuating mechanism 28 in which the sleeve 34 is in the second position on the plug 14. As the sleeve 34 moves from its first position 30 to its second position 32, the first rack 42, connected to the sleeve 34, moves the gear 40 of the actuating mechanism 28. The rotation of the gear 40 moves the second rack 44 to a second position 32, in which the second rack 44 exerts a compressive force on the locking element 18 in the plug sleeve 16. This compressive force moves the locking element 18 of the plug sleeve 16 from a locked position 22 to an unlocked position 20. In this position, the plug 14 can be removed from the plug sleeve 16. An additional sleeve is arranged on the plug sleeve 16, with which the locking element 18 can additionally be moved from a locking position 22 to an unlocking position 20.
