Domain technique
[0001] The present invention relates to the field of vacuum cleaners for vacuuming dust and waste present on a surface to be cleaned, which can for example be tile, parquet, laminate, carpet or rug. State of the art
[0002] A vacuum cleaner, and in particular a handheld or stick vacuum cleaner, is known to include: a suction assembly comprising: ∘ a main body having a suction nozzle through which air is suitable for being drawn into the suction assembly, ∘ a waste separation and collection device mounted on the main body and fluidly connected to the suction nozzle, and ∘ a suction motor housed in the main body and configured to generate an airflow through the suction nozzle and the waste separation and collection device, a suction accessory comprising a connecting nozzle which is configured to be mechanically and fluidly connected to the suction nozzle provided on the main body of the suction assembly,and a first electrical connector which is located on the main body and a second electrical connector which is located on the suction accessory and which is configured to cooperate with the first electrical connector when the connection nozzle provided on the suction accessory is mechanically connected to the suction nozzle provided on the main body.
[0003] The first and second electrical connectors are specifically designed to power an electrical component located directly within the suction accessory or within another accessory that is electrically and fluidly connected to the suction accessory. For example, the suction accessory could be a suction tube configured to be connected to a suction head equipped with a sole designed to be oriented towards a floor to be cleaned, and the suction head could, for example, be equipped with a rotating cleaning brush and a brush drive motor capable of being electrically powered by the suction unit, via the suction accessory, when the suction accessory is connected to the suction nozzle provided on the suction unit.
[0004] As is known, one of the first and second electrical connectors is a male connector with a protective cavity and two male connection pins arranged within the cavity, and the other of the first and second electrical connectors is a female connector with an insertion portion and two female connection pins arranged within the insertion portion and positioned opposite two through-holes opening onto an end face of the insertion portion. Such a vacuum cleaner is more specifically configured such that, when the connection nozzle on the suction accessory is mechanically connected to the suction nozzle on the main body, the insertion portion is automatically inserted into the protective cavity and the two male connection pins are automatically connected to the two female connection pins.
[0005] One disadvantage of this type of vacuum cleaner is that an object, debris or similar, is likely to get into the protective cavity, and in particular between the two male connection pins, when the suction accessory is not connected to the main body, for example during the phases of use or storage of the vacuum cleaner.
[0006] However, the presence of an object or similar between the two male connection pins is likely to prevent the insertion of the insertion part into the protective cavity, or at least to limit the insertion stroke of the insertion part into the protective cavity, and thus prevent a proper electrical connection between the male connection pins and the female connection pins of the first and second electrical connectors, or even cause the two male connection pins to twist, and thus prevent an electrical connection between the male connection pins and the connection pins.
[0007] Furthermore, when a metallic object, such as a paperclip, is inserted into the protective cavity, and particularly between the two male connection pins, it is liable to electrically connect the two male connection pins, and thus induce a short circuit within the vacuum cleaner, which is liable to damage the entire vacuum cleaner. A vacuum cleaner according to the preamble of claim 1 is known, for example, from WO-A-2022035041. Summary of the invention
[0008] The present invention aims to remedy all or part of these drawbacks.
[0009] The technical problem underlying the invention consists in particular of providing a vacuum cleaner which is simple in structure, reliable and economical, while ensuring an optimal electrical connection between a suction accessory and a main body belonging to the vacuum cleaner.
[0010] To this end, the present invention relates to a vacuum cleaner comprising: a suction assembly comprising: a main body having a suction nozzle through which air is suitable for being drawn into the suction assembly, a waste separation and collection device mounted, for example removably, on the main body and fluidly connected to the suction nozzle, and a suction motor housed in the main body, the suction motor having a motor shaft and being configured to generate an airflow through the suction nozzle and the waste separation and collection device, a suction accessory comprising a connection nozzle which is configured to be mechanically and fluidly connected to the suction nozzle provided on the main body of the suction assembly,and a first electrical connector which is disposed on the main body and a second electrical connector which is disposed on the suction accessory and which is configured to cooperate with the first electrical connector, i.e. to be directly electrically connected with the first electrical connector, when the connection nozzle provided on the suction accessory is mechanically connected to the suction nozzle provided on the main body, one of the first and second electrical connectors being a male electrical connector and having a protective cavity, an access opening which leads into the protective cavity and two male connection pins which are disposed in the protective cavity and which extend substantially parallel to each other,and the other of the first and second electrical connectors being a female electrical connector and comprising an insertion portion having two through-holes opening into an end face of the insertion portion, and two female connection pins which are disposed in the insertion portion and located opposite the two through-holes respectively, the insertion portion being configured to be inserted into the protective cavity via the access opening and the two male connection pins being configured to be connected respectively to the two female connection pins via the two through-holes when the connection nozzle provided on the suction accessory is mechanically connected to the suction nozzle provided on the main body, the male electrical connector further comprises a protective element, such as a protective slider,provided with a protective part and movable between a deployed position in which the protective part extends between the two male connection pins and a retracted position, and in that the insertion part is configured to move the protective element from the deployed position to the retracted position when the insertion part is inserted into the protective cavity.
[0011] This configuration of the male electrical connector, and in particular the presence of the protective element, prevents or at least limits the risk of an object or similar being inserted between the male connection pins when the suction accessory is not connected to the main body. Thus, when the connection nozzle on the suction accessory is subsequently connected to the suction nozzle on the main body, a reliable and optimal electrical connection is ensured between the male and female connection pins of the male and female electrical connectors. Furthermore, the presence of the protective element limits the risk of a metallic object being inserted into the protective cavity, and therefore the risk of a short circuit within the vacuum cleaner due to electrical contact between the two male connection pins.
[0012] The vacuum cleaner may also have one or more of the following characteristics, taken alone or in combination.
[0013] According to one embodiment of the invention, the protective element is made of electrically insulating material, that is to say, dielectric or electrically non-conductive material, and for example, plastic.

[0015] According to one embodiment of the invention, each of the male connection pins has a free end that is recessed relative to the access opening. This arrangement of the male connection pins significantly reduces the risk of damage to the male connection pins during the use or storage of the vacuum cleaner.
[0016] According to one embodiment of the invention, the protective part is configured to be recessed relative to the access opening when the protective element is in the deployed position. Such an arrangement of the protective part significantly reduces the risk of damage to the male connection pins during the vacuum cleaner's use or storage.

[0026] According to one embodiment of the invention, the guide device comprises a guide groove extending into the protective cavity and extending parallel to the direction of movement, the guide groove being configured to cooperate with a longitudinal portion, for example a lower longitudinal portion, of the protective part during the movements of the protective member between the deployed position and the retracted position.
[0027] According to one embodiment of the invention, the guide device includes an additional guide groove which extends into the internal housing and which extends parallel to the direction of movement, the additional guide groove being configured to cooperate with a longitudinal portion of the protective part during the movements of the protective member between the deployed position and the retracted position.
[0028] According to one embodiment of the invention, the guide device comprises two lateral guide walls which partially delimit the internal housing and which are configured to be arranged on either side of the protective part when the protective element is in the retracted position, the two lateral guide walls being configured to laterally guide the protective part during the movements of the protective element between the deployed position and the retracted position.

[0030] According to one embodiment of the invention, the guide finger is provided in a rear part of the protective device.
[0031] According to one embodiment of the invention, the guide finger is oriented opposite to the guide groove, for example upwards. Such a configuration of the guide device ensures optimal guidance of the protective element.
[0032] According to one embodiment of the invention, the passage opening forms part of the guiding device.

[0036] According to one embodiment of the invention, the protective part comprises a free end face configured to be substantially flush with, or to protrude from, the free ends of the male connection pins when the protective element is in the deployed position. Such an arrangement of the protective part further reduces the risk of inserting an object or similar device between the two male connection pins.
[0037] According to one embodiment of the invention, the protective element is configured to be fully retracted out of the protective cavity when the protective element is in the retracted position.
[0038] According to one embodiment of the invention, the protective part is substantially flat.

[0043] According to one embodiment of the invention, the insertion part, and for example the end face of the insertion part, is configured to push the protective member back towards the retracted position and against the thrust force exerted by the activating member when the insertion part is inserted into the protective cavity.
[0044] According to one embodiment of the invention, the activating element extends along an extension axis that is offset, for example upwards, from a median longitudinal axis of the protective part. Such an arrangement of the activating element allows the two electrical connection pins to be brought closer together and thus reduces the width of the male electrical connector.

[0088] The protective element 28 more particularly includes a protective part 29 which is configured to extend, for example exclusively, between the two male connection pins 24 when the protective element 28 is in the deployed position, and thus to prevent or at least limit the risks of an object or debris being introduced between the male connection pins 24 when the suction accessory 4 is not connected to the main body 5, which could hinder subsequent connection of the suction accessory 4 to the main body 5. Advantageously, the protective part 29 is substantially flat and extends in the median longitudinal plane of the first electrical connector 18.
[0089] According to one embodiment of the invention, the protective part 29 may have a width of less than 5 mm, advantageously less than 3 mm, and for example about 2.5 mm, and a height of less than 12 mm, advantageously less than 8 mm, and for example about 6 mm, and the protective member 28 may have a length between 15 and 30 mm, advantageously between 18 and 25 mm, and for example about 20.5 mm.

Thus, when the suction accessory 4 is disconnected from the main body 5, the protective element 28 is automatically returned to the deployed position.

[0096] As shown more specifically on the figure 4, the stressing member 34 extends along an extension axis C which is offset, for example upwards, with respect to a median longitudinal axis of the protection part 29. Advantageously, the stressing member 34 extends in the median longitudinal plane of the first electrical connector 18.
[0097] As shown on the figure 4 , the first electrical connector 18 also includes a guiding device configured to guide the protective element 28 in translation along the direction of movement D1 during its movements between the deployed position and the retracted position.
[0098] According to the embodiment shown in the figures, the guide device includes a guide groove 35 which extends into the protective cavity 22, and which is therefore provided on an inner face of a side wall delimiting the protective cavity 22. The guide groove 35 extends parallel to the direction of movement D1, and is more particularly configured to cooperate with a longitudinal portion, for example a lower longitudinal portion, of the protective part 29 during the movements of the protective member 28 between the deployed position and the retracted position.
[0099] The guide device also includes an additional guide groove 36 extending into the internal housing 31 and parallel to the direction of movement D1. The additional guide groove 36 is configured to cooperate with the aforementioned longitudinal portion of the protective part 29 during the movement of the protective element 28 between the deployed and retracted positions. The guide groove 35 and the additional guide groove 36 are specifically provided on the first body part 21.1.
[0100] Advantageously, the guide device further comprises two lateral guide walls 37 that partially delimit the internal housing 31 and are configured to be positioned on either side of the protective portion 29 when the protective element 28 is in the retracted position.
