Technical Field

[0001] The invention relates to an air compression device having a compressor device for compressing air. Background Art

[0002] An air compressor is known from the prior art, which has a compressor for compressing air, an electric motor for driving the compressor device, and a transmission. Summary of the Invention

[0003] The present invention is based on an air compression device having a compressor device for compressing air, an electric motor for driving the compressor device, and a transmission, wherein the compressor device has a compressor axis and the compressor axis is predetermined by the direction of air compression by the compressor device, wherein the electric motor has a motor axis formed by the motor's axis of rotation, and wherein the transmission mechanically connects the electric motor to the compressor device. It is proposed that the transmission arrange the compressor device and the electric motor at an angle relative to each other, wherein the compressor axis and the motor axis enclose an angle in the range between 10° and 80°, in particular between 20° and 70°, and particularly preferably between 30° and 60°.

[0004] The invention enables a particularly compact design of the air compressor, thereby increasing user comfort. The particularly compact design is achieved in that the transmission arranges the compressor device and the electric motor at an angle relative to one another.

[0005] Within the scope of the present invention, an "air compressor" is to be understood as meaning, in particular, a hand-operated air compressor that a user can hold in his or her hand. The air compressor is designed to compress air, in particular ambient air, in order to fill objects with compressed air, such as footballs, basketballs, volleyball balls, or tires such as automobile tires, bicycle tires, or motorcycle tires, or inflatable boats, balloons, etc. The air compressor can be designed, for example, as an air compressor device or an electrically operated air pump.

[0006] The air compression device compresses air using a compressor device. The compressor axis is predetermined along the direction in which the air is compressed by the compressor device.

[0007] The electric motor is designed to drive the compressor device. If electrical energy is supplied to the electric motor, the drive shaft of the electric motor is set into rotation, wherein the drive shaft forms the axis of rotation. In this embodiment, the axis of rotation is the motor axis.

[0008] The transmission mechanically connects the electric motor to the compressor assembly, enabling the electric motor to drive the compressor assembly. A drive shaft of the electric motor at least partially engages the transmission and drives the transmission. Furthermore, the transmission is mechanically connected to the compressor assembly such that when the electric motor drives the transmission, the transmission transmits rotation to the compressor assembly.

[0009] According to the invention, the transmission arranges the compressor device and the electric motor at an angle relative to one another, wherein the compressor axis and the electric motor axis enclose an angle in the range between 10° and 80°, in particular between 20° and 70°, and particularly preferably between 30° and 60°. This makes it possible to provide a particularly compact and convenient air compression device.

[0010] In one embodiment, the transmission is configured as a bevel gear transmission, particularly a crown gear transmission. The transmission includes a transmission gear, particularly a crown gear, rotatably mounted in the transmission housing and connecting the electric motor to the compressor unit. The drive shaft of the electric motor engages the transmission gear. Once the drive shaft is set into rotation, the drive gear transmits the rotation to the transmission gear, thereby causing the transmission gear to rotate. The compressor unit is mechanically connected to the transmission, particularly the transmission gear, via a compressor connecting rod. The transmission gear has at least one receptacle for the compressor connecting rod. The compressor connecting rod can be connected to the transmission gear using a compressor fastening element. For example, the receptacle of the transmission gear can be a threaded opening, allowing the compressor fastening element to be configured as a screw, allowing the compressor connecting rod to be connected to the transmission gear via the screw. It is also conceivable for the transmission gear to include at least one pin as a receptacle, allowing the compressor connecting rod to be connected to the transmission gear via a notch in the compressor connecting rod. When using the transmission, the compressor connecting rod is configured to convert the rotation of the transmission gear into a substantially axial movement. In this case, the substantially axial movement is substantially along the compressor axis.

[0011] In one embodiment, a transmission axis of the transmission encloses an angle in the range of 50° to 120°, in particular 60° to 110°, and particularly preferably 70° to 100°, with the compressor axis and the motor axis, respectively. The transmission axis is the rotational axis of the transmission. When the drive shaft of the electric motor drives the transmission gear and sets it into rotation, the transmission axis is the rotational axis about which the transmission gear rotates. The transmission axis has the same angle in the range of 50° to 120° relative to the motor axis and the compressor axis. However, it is also conceivable that the transmission axis has different angles in the range of 50° to 120° relative to the motor axis and the compressor axis.

[0012] The at least one receiving portion of the transmission gear and the transmission axis can be spaced apart from one another. This means that the at least one receiving portion is configured on the transmission gear so as to be offset from the transmission axis. The transmission can thus convert a rotation of the transmission gear into a substantially axial movement of the compressor connecting rod along the compressor axis.

[0013] In one embodiment, the transmission has at least one first connecting element and at least one second connecting element, wherein the first connecting element connects the compressor device to the transmission, and the second connecting element connects the electric motor to the transmission. To this end, the first connecting element can at least partially receive the compressor device, and the second connecting element can at least partially receive the electric motor. The first and second connecting elements can be configured, for example, in the form of a disk, a washer, a can, a shell, etc. Thus, the first and / or second connecting element can be configured, for example, as a connection receptacle, a connection can, a connection shell, or a connection disk.

[0014] The first connecting element can achieve a positive, non-positive, and / or materially bonded connection between the compressor device and the transmission. It is also conceivable that the first connecting element is integral with the transmission and / or the compressor device. Furthermore, the first connecting element can achieve, for example, a threaded connection, a snap-on connection, a bayonet connection, a hook connection, a connection using at least one fastening element (e.g., a screw, nut, bolt, rivet), etc. between the compressor device and the transmission.

[0015] The second connecting element can achieve a positive, non-positive, and / or materially bonded connection between the electric motor and the transmission. It is also conceivable that the second connecting element is integral with the transmission and / or the electric motor. Furthermore, the second connecting element can achieve, for example, a threaded connection, a snap-on connection, a bayonet connection, a hook connection, a connection using at least one fastening element (e.g., a screw, nut, bolt, rivet), etc. between the electric motor and the transmission.

[0016] In one embodiment, the first connecting element and the second connecting element are formed integrally with the transmission housing. It is also conceivable that the first connecting element and the second connecting element are integral.

[0017] In one embodiment, the compressor device comprises a compressor housing, wherein a first connecting element connects the compressor housing to the transmission. The first connecting element can at least partially receive the compressor housing and arrange it on the transmission. In addition, the first connecting element can achieve a form-locking, force-locking, and / or material-locking connection to the transmission. The compressor housing can be designed, for example, in the form of a can, shell, cage, or frame. Thus, the first connecting element can form a connection with the compressor housing, for example, by means of a threaded connection, a snap-on connection, a bayonet connection, a hook connection, or a connection by means of at least one fastening element (e.g., a screw, nut, bolt, rivet), or the like.

[0018] The compressor housing further includes a compressor connecting element for connecting the air compression device to at least one compressed air hose. The compressor connecting element can be configured as a compressor coupling or a compressor plug. The compressor connecting element is configured so that it can form a positive-locking and / or non-positive-locking connection with the compressed air hose. The compressed air hose can be rotatably connected to the compressor connecting element. Compressed air can flow to the compressor connecting element via the compressor outlet and the compressor valve. When the compressed air hose is connected to the compressor connecting element, compressed air can flow into the compressed air hose so that a user can fill an object with air.

[0019] In one embodiment, a compressor device includes a compressor cylinder and a compressor piston, wherein the compressor piston is configured to compress air in the compressor cylinder, and a first connecting element connects the compressor cylinder to a transmission. The compressor housing is configured to at least receive the compressor cylinder. The compressor housing can at least partially surround the compressor cylinder. Furthermore, the compressor housing can be arranged around the compressor cylinder in a cage-like manner. The compressor housing can receive the compressor cylinder with a positive and / or non-positive fit, wherein it is also conceivable that the compressor cylinder and the compressor housing are integral. The compressor cylinder can be configured in a pot-like, cylinder-like, or shell-like manner. The compressor cylinder can have at least one compressor inlet and at least one compressor outlet. The compressor inlet is configured to allow air to enter the compressor cylinder. The compressor outlet is configured to allow compressed air to escape from the compressor cylinder. A compressor valve is disposed at the compressor outlet, wherein the compressor valve substantially closes the compressor outlet. The compressor valve is configured to allow compressed air at a predetermined pressure to escape. To this end, the compressor valve opens, and compressed air escapes from the compressor cylinder via the compressor outlet.

[0020] In addition, the first connecting element can at least partially receive the compressor cylinder and connect it to the transmission. The first connecting element can achieve a form-fitting, force-fitting, and / or material-locking connection between the compressor cylinder and the transmission. For example, the first connecting element can be configured as a threaded connection, a snap-on connection, a bayonet connection, a hook connection, a connection to the compressor cylinder using at least one fastening element (e.g., a screw, nut, bolt, rivet), or the like.

[0021] In one embodiment, the first connecting element is additionally designed to guide the compressor piston along the compressor axis, particularly when driven by an electric motor. To this end, the first connecting element comprises at least one piston guide element. The piston guide element can receive the compressor piston at least in a form-fitting manner and guide it along the compressor axis, while the electric motor drives the compressor arrangement. When using the piston guide element, the compressor connecting rod can convert a rotation of the transmission (particularly a transmission gear) into a substantially axial movement of the compressor piston essentially without losses. The piston guide element can be configured, for example, in the form of a hollow cylinder, as an opening, a notch, a recess, a rail, a strip, or a combination of these embodiments.

[0022] The compressor piston is connected to a compressor connecting rod. The compressor connecting rod can be connected to the compressor piston in a form-locking, force-locking, and / or materially bonded manner, wherein it is also conceivable that the compressor piston and the compressor connecting rod are integral. In one embodiment, the compressor connecting rod can be connected to the compressor piston in a pivotable and / or tiltable manner, in particular, it can be supported. The compressor connecting rod is mechanically connected to a transmission. The transmission can thus drive the compressor connecting rod.

[0023] The compressor piston is movably supported in the compressor cylinder. Thus, the compressor piston is configured such that, in a first operating direction, air in the compressor cylinder can be compressed when the compressor piston is in use, while in a second operating direction, the compressor cylinder can be filled with air. In the first operating direction, the compressor piston moves from the compressor inlet to the compressor outlet, thereby compressing the air in the compressor cylinder. In the second operating direction, the compressor piston moves from the compressor outlet to the compressor inlet, thereby filling the compressor cylinder with air. To this end, the compressor piston includes at least one compressor seal. The compressor seal is at least partially circumferentially arranged around the compressor piston. Furthermore, the compressor seal can be lip-shaped, such that it can be substantially airtight in the first operating direction and substantially airtight in the second operating direction. The compressor seal can form a positive connection between the compressor piston and the compressor cylinder in the first operating direction, substantially preventing air in the compressor cylinder from escaping through the compressor inlet. Furthermore, the compressor seal can form a positive connection between the compressor piston and the compressor cylinder in the second operating direction, such that air can flow into the compressor cylinder through the compressor seal.

[0024] In this embodiment, the compressor axis is predetermined along the direction in which the air is compressed by the compressor device. Thus, the compressor axis is here along the first working direction of the compressor piston.

[0025] Thus, the compressor arrangement comprises a compressor housing, a compressor cylinder, a compressor piston, a compressor connecting rod and a compressor valve. Additionally, the compressor arrangement has a compressor seal, a compressor inlet and a compressor outlet.

[0026] In one embodiment, the air compression device comprises an elongated housing, wherein the elongated housing accommodates at least one energy supply device, a transmission, a compressor device, and an electric motor for supplying electrical energy to the air compression device. The elongated housing comprises an elongated shape, for example, in the form of a cylinder, a wedge, a cuboid, or a prism. The energy supply device is configured to supply electrical energy to the air compression device. Preferably, the air compression device is a battery-operated air compression device that can be operated by at least one battery. Thus, electrical energy is provided by the energy supply device by means of at least one battery. The battery of the air compression device can be configured as a permanently installed battery or a replaceable battery. The permanently installed battery of the air compression device can be arranged in the elongated housing. The replaceable battery can be releasably connected to the air compression device, allowing a user to connect and remove the replaceable battery from the air compression device. Alternatively, the air compression device can be configured as a mains-operated air compression device.

[0027] The elongated housing can accommodate the energy supply device, the transmission, the compressor device, and the electric motor. The elongated housing can receive the energy supply device, the transmission, the compressor device, and the electric motor at least in a form-fitting manner. It is conceivable that the elongated housing receives these elements or connects them to the housing using at least one fastening element within the housing.

[0028] In one embodiment, the transmission is arranged between the energy supply device, the electric motor, and the compressor. The transmission can represent a central arrangement for the air compression device. The energy supply device is arranged in a first region of the air compression device. The compressor device and the electric motor are arranged in a second region of the air compression device. The transmission is arranged essentially between the first and second regions. This allows for a particularly ergonomic design.

[0029] In one embodiment, the elongated housing has a Y-shaped configuration. The elongated housing has at least three housing axes that extend outwards into the Y-shape. These three housing axes intersect at at least one intersection point. The transmission can be arranged at the intersection point of the three housing axes. The energy supply device can be arranged on the first housing axis. The compressor axis forms the second housing axis, allowing the compressor device to be arranged on the second housing axis. The motor axis can form the third housing axis. The motor can be arranged on the third housing axis.

[0030] Also conceivable, the elongated housing is configured in a triangular shape. Here, the elongated housing then has a triangular shape along the first housing axis in the cross section.

[0031] In one embodiment, the energy supply device encloses an angle with the motor axis in the range of 100° to 200°, in particular 120° to 180°, and particularly preferably 140° to 160°. The first housing axis can be configured at an angle with the motor axis, in particular the third housing axis, in the range of 100° to 200°. Thus, the energy supply device and the motor have an angle in the range of 100° to 200°. This improves user comfort by achieving a balanced weight distribution of the energy supply device and the motor, so that the compressed air device can be held in a balanced manner in the user's hand.

[0032] In one embodiment, the energy supply device encloses an angle with the compressor axis in the range of 110° to 210°, in particular 130° to 190°, and particularly preferably 150° to 170°. The energy supply device can be arranged on the first housing axis such that the first housing axis can enclose an angle with the compressor axis, in particular the second housing axis, in the range of 110° to 210°. The energy supply device is arranged on the first housing axis relative to the compressor device and the electric motor in such a way that the most even weight distribution is achieved, thereby improving user operability.

[0033] In one embodiment, the air compression device comprises a control unit for controlling the air compression device, wherein a transmission is arranged between the control unit and the electric motor and the compressor device. The control unit is configured to control at least the energy supply device and / or the electric motor. It is further conceivable that the control unit can control the compressor device. In this case, the housing can receive the control unit and arrange it within the housing. The control unit can be arranged substantially parallel to or transversely to, in particular perpendicularly to, the energy supply device. If the control unit is arranged substantially parallel to the energy supply device, the control unit can be oriented along a first housing axis. If the control unit is arranged transversely to, in particular perpendicularly to, the energy supply device, the control unit is arranged transversely to, in particular perpendicularly to, the first housing axis.

[0034] In one embodiment, the control unit and the compressor axis enclose an angle in the range of 110° to 210°, in particular 130° to 190°, and particularly in particular 150° to 170°. With an angle in the range of 110° to 210° between the control unit and the compressor axis, a particularly convenient air compression device can be provided.

[0035] In one embodiment, the air compression device has an output and input unit, wherein the output and input unit is arranged substantially parallel to the compressor device, in particular the compressor axis. The output and input unit can be at least partially arranged in or on the housing. The output and input unit is configured to output visual, auditory and / or tactile information to the user. In this case, the visual, auditory and / or tactile information can be an adjustable pressure, the current pressure, the target pressure, a warning indication to the user when the pressure is reached, the current state of the energy supply device, the temperature of the compressor device or the temperature of the energy supply device. The output and input unit can be configured, for example, as at least one display, one LED, multiple LEDs, a vibration element and / or a loudspeaker. In addition, the output and input unit can be configured, for example, as at least one touch-sensitive display, an operating element, a main switch and / or a microphone.

[0036] The output and input unit is arranged substantially parallel to the compressor device, in particular the compressor axis. Within the scope of the present invention, "substantially parallel" is to be understood as parallel, but also encompasses angles of up to 10°. Thus, the output and input unit can also enclose an angle of up to 10° with the compressor device, in particular the compressor axis. This ensures that the output and input unit remains unobstructed in the user's field of view during use of the air compressor device.

[0037] Furthermore, the elongated housing has substantially no visible fastening elements, such that the fastening elements (eg, screws, rivets, nuts, hooks, etc.) are substantially invisible to a user during use of the compressed air device.

[0038] Additionally or alternatively, the housing can have a housing connecting element, so that the compressed air hose can be connected to the housing connecting element.

[0039] The housing can also include at least one storage device, wherein the storage device is configured to store accessories for the compressed air device. The storage device can be configured, for example, as a storage compartment, a storage slot, a storage receptacle, or the like. The storage device can receive accessories (e.g., an adapter for a bicycle valve, a ball needle, a valve cap, or an adapter for low-pressure applications) and connect them to the housing at least in a form-fitting manner. The storage device can be covered, in particular closed, by a storage cover. The storage cover can be arranged on the housing in a movable and / or pivotable manner.

[0040] The compressed air hose can be fastened to the elongated housing by means of at least one fastening element. For example, the elongated housing can have a receptacle (particularly a U-shaped or C-shaped snap-on receptacle), a hook, a rail, a strip, a groove, a recess, a notch, an opening, etc. Additionally or alternatively, the compressed air hose can, for example, have a strip, a rail (particularly a T-shaped rail), a ring, a hook, etc. It is also conceivable that the compressed air hose can be connected to the elongated housing using a magnetic connection.

[0041] Furthermore, the air compression device can include at least one pressure measuring module, which is configured to measure at least one pressure. To this end, the pressure measuring module can measure the pressure generated by the compressor device, as well as the pressure within an object. The pressure measuring module can be arranged on the housing, the transmission, the compressor device, the electric motor, the energy supply device, and / or the control unit. Furthermore, the air compression device (in particular the compressor device) and / or the pressure measuring module can include at least one overpressure unit. The overpressure unit is configured to allow the pressure to escape from the compressor device when the pressure exceeds an adjustable and / or predefined pressure.

[0042] In one embodiment, the electric motor is additionally designed to generate an air flow within the housing. It is further proposed that the air compression device has an air guide device that guides the air flow from the energy supply device to the compressor device and the electric motor using a transmission, wherein the air guide device is arranged at least in sections within the elongated housing.

[0043] Additionally, the electric motor is configured to generate an air flow within the elongated housing. To this end, the electric motor may include at least one fan wheel. Once the drive shaft of the electric motor is set into rotation, the fan wheel is also set into rotation. Thus, the rotating fan wheel can generate an air flow within the elongated housing. The fan wheel may be substantially arranged on the drive shaft. Alternatively, it is conceivable that the drive shaft and the fan wheel are mechanically connected so that the rotation of the drive shaft is transmitted to the fan wheel.

[0044] The compressor device, the electric motor, the transmission and the energy supply device are at least partially arranged in an elongated housing. The elongated housing at least partially, in particular substantially completely, surrounds the compressor device, the electric motor, the transmission and the energy supply device and thus arranges them in the elongated housing.

[0045] The elongated housing also has at least one air inlet opening, wherein the air inlet opening is configured to allow air to enter the elongated housing. This allows an air flow to be generated once air reaches, in particular, is drawn into, the elongated housing through the air inlet opening, causing the electric motor to rotate. The air inlet opening can, for example, be configured to be at least partially annular, slit-shaped, circular, oval, elliptical, or polygonal (e.g., triangular, quadrilateral, pentagonal, etc.). The air inlet opening can be assigned to a power supply device so that the air inlet opening is positioned closer to the power supply device. The housing also has at least one air outlet opening, which is configured to discharge air from the housing. This allows an air flow to flow out of the housing through the air outlet opening, in particular, to be pumped out of the housing. For example, the air outlet opening can be configured to be at least partially annular, slit-shaped, circular, oval, elliptical, or polygonal (e.g., triangular, quadrilateral, pentagonal, etc.). The air outlet opening can be assigned to a compressor device and / or the electric motor so that the air outlet opening is positioned closer to the compressor device and / or the electric motor.

[0046] In addition to efficiently cooling at least the energy supply device, the transmission, the compressor device and the electric motor, the air flow within the elongated housing of the air compressor device also enables a suitable air supply to the compressor device so that the compressor device can compress the provided air during operation.

[0047] Advantageously, the air compression device comprises an air guiding device that guides the air flow from the energy supply device to the compressor device and the electric motor using a transmission, wherein the air guiding device is arranged at least in sections within an elongated housing. The elongated housing can receive and at least partially enclose the air guiding device. Furthermore, the elongated housing can form a positive-locking, non-positive-locking, and / or material-locking connection with the air guiding device. It is also conceivable that the air guiding device is integral with the elongated housing.

[0048] The air guiding device is configured to direct the air flow from the energy supply device via the transmission to the compressor device and the electric motor. Furthermore, when the transmission is used, the air guiding device arranges the energy supply device in a first region of the air compressing device. Furthermore, when the transmission is used, the air guiding device arranges the compressor device and the electric motor in a second region of the air compressing device. The transmission is substantially arranged between the first region of the air compressing device and the second region of the air compressing device. In particular, the transmission is located between the energy supply device, the compressor device, and the electric motor, and isolates the first region from the second region. The air guiding device directs the air flow from the first region of the air compressing device via the transmission to the second region of the air compressing device. Thus, the air guiding device ensures that the air flow can flow from the first region of the air compressing device to the second region of the air compressing device substantially only via the transmission.

[0049] In one embodiment, the air guiding device comprises at least one air guiding element, wherein the air guiding element guides the air flow from the energy supply device to the transmission. The air guiding element can be connected to the air guiding device by form-locking, force-locking, and / or material-locking. It is also conceivable that the air guiding element and the air guiding device are integral. The air guiding element guides the air flow within the elongated housing from the first area of the air compressing device to the transmission. Furthermore, the air guiding element is designed, in particular arranged in the housing, so that it additionally substantially obstructs the air flow from the first area of the air compressing device to the transmission, without the air flow having to flow to the transmission. Thus, the air flow essentially flows from the first area of the air compressing device to the second area of the air compressing device only when the air guiding element and the transmission are used.

[0050] In one embodiment, the air guide element is configured as a transmission cover of the transmission. For this purpose, the transmission has a transmission cover. The transmission cover can be configured, for example, in the form of a disk, a shell or a pot.

[0051] The transmission cover can be arranged on the transmission, wherein the transmission can receive the transmission cover. To this end, the transmission can have at least one transmission cover receptacle for receiving the transmission cover. The transmission cover can be connected to the transmission by form-locking, force-locking, and / or material-locking. It is conceivable that the transmission cover can be connected to the transmission by means of at least one fastening element (e.g., a screw, nut, rivet, etc.). In this case, the transmission cover can have a receptacle for the at least one fastening element, such as an opening. Furthermore, the transmission cover can at least partially close or surround the transmission. Furthermore, the transmission cover can have at least one air guide hood. The air guide hood can be connected to the transmission cover by form-locking, force-locking, and / or material-locking. The air guide hood is configured to guide an air flow from the energy supply device into the transmission. It is also conceivable that the transmission cover has at least one air inlet opening. The air inlet opening of the transmission cover can be slit-shaped, circular, or oval-shaped, for example. For example, the transmission cover can have multiple air inlet openings, ranging from 2 to 20.

[0052] It is possible that the transmission cover has a connecting element for the housing. The connecting element of the transmission cover is provided to establish a connection between the transmission cover and the housing. The connecting element of the transmission cover can be designed, for example, as a strip, a projection, a hook, or a nose. The connecting element of the transmission cover can be connected to the transmission cover in a form-fitting, force-fitting, and / or materially locking manner, or the connecting element of the transmission cover can be integral with the transmission cover. The connecting element of the transmission cover can establish a form-fitting and / or force-fitting connection between the transmission cover and the housing.

[0053] Alternatively, the transmission cover can receive the transmission. For this purpose, the transmission cover can be configured in a shell or pot shape. Here, the transmission can then be fitted into the transmission cover and form a positive and / or force-locking connection.

[0054] In one embodiment, an air guiding element is arranged between the transmission and the elongated housing. The air guiding element can thereby form a positive and / or non-positive connection to the transmission and / or the elongated housing. Furthermore, the air guiding element can be fitted at least partially into the transmission and / or the elongated housing. The air guiding element is arranged between the transmission and the elongated housing so that an air flow from the first region of the air compression device can be guided into the transmission. The transmission and / or the elongated housing can receive the air guiding element. The air guiding element can be arranged at least partially circumferentially around the transmission. It is also conceivable that the air guiding element is at least partially circumferentially attached to the elongated housing.

[0055] In one embodiment, the air guiding element is configured as a seal, in particular a rubber seal, which is arranged at least partially circumferentially around the transmission. The seal is configured so that it can be fitted at least partially into the transmission. The transmission can have a receptacle for the seal, which can receive the seal at least in a form-fitting manner. Furthermore, the seal can be fitted into an elongated housing, wherein the elongated housing can have a receptacle for the seal. The seal can be elastically deformable.

[0056] In one embodiment, the transmission receives the elongated housing in the form of a keyway connection, wherein the keyway connection constitutes the air guide element. The keyway connection can be constructed circumferentially around the transmission and the elongated housing. In this case, the transmission can constitute the groove or the key, wherein the groove or the key is connected to the transmission in a form-locked, force-locked and / or material-locked manner. It is also conceivable that the groove or the key is integral with the transmission. In addition, the elongated housing can constitute the key or the groove, wherein the key or the groove is connected to the elongated housing in a form-locked, force-locked and / or material-locked manner. It is feasible that the key or the groove is integral with the housing. Due to this keyway connection, the elongated housing can be fitted into the elongated housing at least in sections, or vice versa.

[0057] In one embodiment, the air guiding device has at least one air guiding opening, wherein the air guiding opening guides the air flow from the energy supply device into the transmission. The air guiding opening can be designed, for example, in a circular or oval shape, but can also be designed in a rectangular, square, polygonal, or slit-shaped manner. It is also possible to provide more than one air guiding opening in order to guide the air flow from the energy supply device (in particular, the first region of the air compressor) into the transmission.

[0058] In one embodiment, the air guiding device comprises at least one first air guiding guide element and at least one second air guiding guide element, wherein the first air guiding guide element guides at least one first partial air flow of the air flow from the transmission to the compressor device, and the second air guiding guide element guides at least one second partial air flow of the air flow from the transmission to the electric motor. The first air guiding guide element and the second air guiding guide element are arranged on the transmission and can be connected to the transmission in a form-fitting, force-fitting, and / or materially bonding manner, wherein it is also conceivable that they are integral with the transmission.

[0059] The first air guiding guide element can be configured as a first air guiding guide slot or a first air guiding guide opening. For example, the first air guiding guide element can be configured in the form of a hollow cylinder or a tube, wherein the first air guiding guide element can also, for example, have a polygonal shape or can be configured in the form of a slit or at least a section of an annular shape. The first air guiding guide element is configured to guide the first partial air flow in the direction of the compressor device once the air flow enters the transmission. Once the compressor device is operated, the compressor device essentially compresses the air provided by the first partial air flow.

[0060] The second air guidance guide element can be configured as a second air guidance guide slot or a second air guidance guide opening. For example, the second air guidance guide element can be configured at least in sections as an annular opening or a slit-like configuration. The second air guidance guide element is configured to direct a second partial air flow to the electric motor as soon as the air flow flows into the transmission. The second partial air flow is provided for cooling at least the electric motor.

[0061] In one embodiment, the first connecting element additionally forms the first air guiding guide element, and the second connecting element additionally forms the second air guiding guide element. It is also conceivable that the first air guiding guide element is integral with the first connecting element, and the second air guiding guide element is integral with the second connecting element.

[0062] In one embodiment, the air guiding device has at least one further air guiding element, wherein the further air guiding element guides the air flow, in particular the second partial air flow, from the electric motor to the compressor device. The further air guiding element is configured to guide the air flow, in particular the second partial air flow, from the electric motor in the direction of the compressor device for cooling the compressor device. As soon as the electric motor generates an air flow using the fan wheel and this air flow, in particular the second partial air flow, flows substantially through the electric motor for cooling the electric motor, the further air guiding element guides the air flow, in particular the second partial air flow, in the direction of the compressor device.

[0063] The additional air-guiding element is arranged at the motor. The additional air-guiding element can be formed on the motor, the transmission, the elongated housing, and / or the compressor assembly. Thus, the additional air-guiding element can be connected to the motor, the transmission, the elongated housing, and / or the compressor assembly by a form-fitting, force-fitting, and / or material-locking manner. It is also conceivable that the additional air-guiding element is integral with the transmission, the motor, the elongated housing, and / or the compressor assembly. Preferably, the elongated housing forms the additional air-guiding element.

[0064] In one embodiment, the electric motor is additionally configured to generate a further air flow, and the air guiding device, in particular using additional air guiding elements, guides the further air flow from the electric motor to the compressor device. Once the electric motor is in operation, the further air flow is generated using the fan wheel. The elongated housing has at least one further air inlet opening, through which air for generating the further air flow can flow into the elongated housing. The further air inlet opening can be configured on the electric motor in the housing. For example, the further air inlet opening can be configured to be at least partially annular, slit-shaped, circular, oval, elliptical, or polygonal (e.g., triangular, quadrilateral, pentagonal, etc.).

[0065] In addition to guiding the air flow, in particular the second partial air flow, the air guiding device is additionally configured to guide a further air flow from the electric motor toward the compressor unit, particularly when using additional air guiding elements. This allows the air flow, in particular the second partial air flow, to mix with the further air flow after it has flowed through the electric motor. The further air flow is provided for cooling the electric motor and / or the compressor unit. After the air flow, in particular the second partial air flow, and the further air flow have cooled the compressor unit, the air guiding device can guide the air flow, in particular the second partial air flow and the further air flow, toward an air outlet opening. The air flow, in particular the second partial air flow and the further air flow can flow out of the housing through the air outlet opening.

[0066] In one embodiment, the transmission comprises a transmission housing, and the transmission housing forms an air guide. The elongated housing can form a positive, force-locking, and / or integrally bonded connection to the transmission housing. Furthermore, the transmission housing can accommodate or form an air guide element. Furthermore, the transmission housing air guide element can form a force-locking, form-locking, and / or integrally bonded connection to the transmission housing. It is also conceivable that the first air guide element and the second air guide element form a force-locking, form-locking, and / or integrally bonded connection to the transmission housing, or even be integral with the transmission housing. The air guide opening can be configured as at least one notch or opening in the transmission housing.

[0067] Preferably, the first air guiding guide element, the first connecting element, the second air guiding guide element, the second connecting element and the air guiding opening are integral with the transmission housing.

[0068] In one embodiment, the control unit for controlling the air compressor is arranged in the housing substantially parallel to the energy supply device.

[0069] The air flow is additionally designed to cool the control unit in addition to the energy supply device. As soon as the electric motor generates the air flow, the air flow can flow along the energy supply device and the control unit for cooling. BRIEF DESCRIPTION OF THE DRAWINGS

[0089] The housing 110 includes at least one storage device 112. The storage device 112 is configured to store accessories for the air compressor 100. Here, the storage device 112 is exemplarily configured as a storage compartment, for which see also Figure 7 .

[0090] The compressor device 120, the electric motor 140, the transmission 160, the energy supply device 180 and the control unit 106 are arranged at least in sections in the housing 110. The housing 110 receives the energy supply device 180, the transmission 160, the compressor device 120, the electric motor 140 and the control unit 106 at least in a form-fitting manner. Here, the housing 110 of the air compression device 100 is designed as an elongated housing 110. Here, the elongated housing 110 has an elongated shape, which is designed in the form of a wedge as an example, for this purpose, see also Figure 2 and Figure 5.

[0091] In this embodiment, the elongated housing 110 includes two air inlet openings 114, which are configured here in the first region 102 of the air compressing device 100 at the energy supply device 180 and are elliptically configured here by way of example.

Furthermore, the elongated housing 110 includes two air outlet openings 118, which are configured here in the second region 104 of the air compressing device 100 at the compressor device 120. Furthermore, the air outlet openings 118 are slit-shaped by way of example, see also Figure 2 and FIG. 5 . The air outlet opening 118 is configured to direct air out of the elongated housing 110 .

[0092] The air compressing device 100 further comprises an air guiding device 200. The air guiding device 200 is arranged at least partially in the elongated housing 110, see also Figure 2 and Figure 3. In this case, the elongated housing 110 receives the air guiding device 200 and at least partially surrounds it. In addition, the air guiding device 200 is designed to guide the air flow 190 from the energy supply device 180 to the compressor device 120 and the electric motor 140 using the transmission 160. As soon as the electric motor 140 is supplied with electrical energy, the fan wheel 146 of the electric motor 140 is set into rotation and thus generates the air flow 190 in the elongated housing 110. In this case, the air enters the elongated housing 110 through the air inlet opening 114 and exits the elongated housing 110 through the air outlet opening 118, see also Figure 2 and Figure 3 .

[0093] In addition, the air guiding device 200 arranges the energy supply device 180 in the first region 102 of the air compressing device 100 using the transmission 160. The air guiding device 200 also arranges the compressor device 120 and the electric motor 140 in the second region of the air compressing device 100 using the transmission 160. The air guiding device 200 is designed to guide the air flow 190 from the first region 102 via the transmission 160 into the second region 104. The transmission 160 is arranged essentially between the first region 102 and the second region 104.

[0094] Figure 2 A first longitudinal section of air compression device 100 is shown. Transmission 160 includes a first connecting element 168 and a second connecting element 170 (see also FIG4 ). Compressor device 120 is connected to transmission 160 via first connecting element 168, wherein first connecting element 168 at least partially accommodates compressor device 120. First connecting element 168 provides a positive-locking connection between compressor device 120 and transmission 160. In this embodiment, first connecting element 168 is designed as a washer and is integral with transmission 160. Electric motor 140 is connected to transmission 160 via second connecting element 170, wherein second connecting element 170 at least partially accommodates electric motor 140. Furthermore, second connecting element 170 establishes a positive-locking connection between electric motor 140 and transmission 160. Using second connecting element 170, electric motor 160 can be connected to transmission housing 166 by means of at least one fastening element (not shown in detail). Here, second connecting element 170 is designed as a shell. In this embodiment, the first connecting element 168 and the second connecting element 170 are integral with the transmission housing 166 .

[0095] Compressor device 120 has a compressor axis 122, wherein compressor axis 122 is predetermined along a direction 123 in which the air is compressed by compressor device 120. As soon as electric motor 140 is supplied with electrical energy, drive shaft 141 of electric motor 140 is set into rotation and thereby forms an axis of rotation 142. Axis of rotation 142 of electric motor 140 here represents motor axis 144.

[0096] The transmission 160 arranges the compressor unit 120 and the electric motor 140 at an angle relative to one another. The compressor axis 122 and the motor axis 144 enclose an angle 400 in the range between 10° and 80°. The electric motor 140 is mechanically connected to the compressor unit 120 using the transmission 160. Thus, the electric motor 140 drives the compressor unit 120. The drive shaft 141 engages at least partially in the transmission 160.

[0097] The transmission 160 is designed here as a bevel gear transmission 162. The transmission 160 comprises a transmission gear 164. The transmission gear 164 is rotatably mounted in a transmission housing 166. The transmission housing 166 is designed to connect the electric motor 140 to the compressor unit 120. The drive shaft 141 engages in the transmission gear 164 in a form-fitting manner. Once the transmission gear 164 is set in rotation, an axis of rotation 161 of the transmission 160 is formed, which is represented here as the transmission axis 163. The transmission axis 163 is perpendicular to the transmission axis 164. Figure 2 drawing plane.

[0098] The compressor unit 120 has a compressor connecting rod 124. The compressor connecting rod 124 mechanically connects the compressor unit 120 to the transmission 160. For this purpose, the compressor connecting rod 124 is connected to a transmission gear 164. The transmission gear 164 includes a receptacle 165 for the compressor connecting rod 124 and is connected to the transmission gear 164 by means of a compressor fastening element 125. In this embodiment, the receptacle 165 of the transmission gear 164 is designed as a threaded opening. The compressor fastening element 125 is designed here as a screw with a nut. Here, the receptacle 165 of the transmission gear 164 and the transmission axis 163 are spaced apart from each other, see also FIG. Figure 3 Thus, the driver 160 converts rotation of the driver gear 164 into substantially axial movement of the compressor connecting rod 124 along the compressor axis 122 .

[0099] The compressor device 120 further comprises a compressor housing 126. The compressor housing 126 is connected to the transmission 160 using a first connecting element 168. The compressor housing 126 is designed in a cage-like manner and fits at least partially into the first connecting element 168, see also Figure 3and FIG. 4 . Furthermore, the compressor housing 126 has a compressor connecting element 127 , which is configured to connect the compressed air device 100 to the compressed air hose 300 . In this embodiment, the compressor connecting element 127 is configured as a compressor clutch. The compressor connecting element 127 forms a positive-locking connection with the compressed air hose 300 . The compressed air hose 300 is rotatably connected to the compressor connecting element 127 .

[0100] Compressor device 120 also includes a compressor cylinder 130 and a compressor piston 131. Compressor piston 131 compresses air in compressor cylinder 130. A first connecting element 168 additionally connects compressor cylinder 130 to transmission 160 in a form-fitting manner. Compressor housing 126 receives compressor cylinder 130, at least partially enclosing it. Compressor housing 126 is arranged around compressor cylinder 130 in a cage-like manner. Compressor cylinder 130 is shaped like a can. Compressor cylinder 130 includes a compressor inlet 132 and a compressor outlet 128. Air can flow into compressor cylinder 130 via compressor inlet 132. Compressed air can flow out of compressor cylinder 130 via compressor outlet 128. Compressor device 120 includes a compressor valve 129, which is arranged at compressor outlet 128. Compressor valve 129 essentially closes compressor outlet 128, allowing compressed air at a predetermined pressure to escape. The compressed air flows to the compressor connecting element 127 via the compressor outlet 128 and the compressor valve 129 .

[0101] Here, the compressor piston 131 is connected to the compressor connecting rod 124 at least in a form-fitting manner. The compressor connecting rod 124 is pivotably mounted in the compressor piston 131. Furthermore, the compressor piston 131 is movably mounted in the compressor cylinder 130. The compressor piston 131 includes a compressor seal 133, which is arranged at least partially circumferentially around the compressor piston 131. The compressor seal 133 is lip-shaped. The compressor seal 133 is substantially airtight in a first operating direction of the compressor piston 131 and substantially airtight in a second operating direction of the compressor piston 131. Thus, in the first operating direction of the compressor piston 131, air in the compressor cylinder 130 can be compressed, while in the second operating direction of the compressor cylinder 130, air can flow into the compressor cylinder 130. In this embodiment, the first operating direction of the compressor piston 131 is in the direction 123 of air compression, while the second operating direction of the compressor piston 131 is opposite to the direction 123 of air compression.

[0102] Thus, the compressor arrangement 120 has a compressor housing 126 , a compressor cylinder 130 , a compressor piston 131 , a compressor seal 133 , a compressor connecting rod 124 and a compressor valve 129 .

[0103] First connecting element 168 is additionally provided for guiding compressor piston 131 along compressor axis 122 when electric motor 140 drives transmission gear 164. To this end, first connecting element 168 comprises a piston guide element 169. Piston guide element 169 receives compressor piston 131 at least in a form-fitting manner and guides compressor piston 131 along compressor axis 122. In this embodiment, piston guide element 169 is designed as an opening in the form of a hollow cylinder.

[0104] The compressed air device 100 includes a pressure measuring module 280 (see also FIG4 ). The pressure measuring module 280 measures the pressure generated by the compressor device 120 and the pressure in the object connected via the compressed air hose 300 . The pressure measuring module 280 is arranged on the transmission 160 (see also FIG4 ). The compressed air device 100 also includes an overpressure unit 282. If an adjustable or predefined pressure is exceeded, the overpressure unit 282 releases the pressure from the compressor device 120.

[0105] The elongated housing 110 is configured in a Y-shape. Here, the elongated housing 110 includes three housing axes 410, 412, 414. These three housing axes 410, 412, 414 define the Y-shape. Furthermore, the three housing axes 410, 412, 414 intersect at an intersection. In this embodiment, the transmission 160 is arranged at the intersection of the three housing axes 410, 412, 414. The energy supply device 180 is arranged on the first housing axis 410. The second housing axis 412 is formed by the compressor axis 122, wherein the compressor device 120 is arranged on the second housing axis 412. The third housing axis 414 is configured by the motor axis 144. Here, the motor 140 is then arranged on the third housing axis 414.

[0106] The transmission axis 163 encloses angles 402 and 404 with the compressor axis 122 and the motor axis 144, respectively, in the range of 50° to 120°. The angle 402 between the transmission axis 163 and the compressor axis 122 is in the range of 50° to 120°. Furthermore, the angle 404 between the transmission axis 163 and the motor axis 122 is in the range of 50° to 120°.

[0107] Energy supply device 180 encloses an angle 406 with motor axis 144 in the range of 100° to 200°. In this embodiment, first housing axis 410 forms an angle 406 with motor axis 144 in the range of 100° to 200°. Furthermore, energy supply device 180 encloses an angle 408 with compressor axis 122 in the range of 110° to 210°. In this embodiment, angle 408 is formed between first housing axis 410 and compressor axis 122.

[0108] In this embodiment, control unit 106 is arranged substantially parallel to energy supply device 180, so that control unit 106 is arranged substantially parallel to and along first housing axis 410. Control unit 106 thus forms an angle 409 with compressor axis 122 in the range of 110° to 210°.

[0109] The air compressing device 100 comprises an air guiding device 200. The air guiding device 200 guides the air flow 190 from the energy supply device 180 to the compressor device 120 and also to the electric motor 140 by means of the transmission 160. The air guiding device 200 is arranged at least partially within the elongated housing 110.

In addition, the air guiding device 200 comprises an air guiding element 210, see also Figure 4a The air-guiding element 210 is designed such that it guides the air flow 190 from the energy supply device 180 to the transmission 160 .

[0110] The air guiding device 200 further comprises a first air guiding guide element 220 and a second air guiding guide element 222. The first air guiding guide element 220 guides a first partial air flow 192 of the air flow 190 from the transmission 160 to the compressor device 120. Here, the first air guiding guide element 220 is configured as a first air guiding guide opening in the form of a hollow cylinder. The second air guiding guide element 222 guides a second partial air flow 194 of the air flow 190 from the transmission 160 to the electric motor 140. Here, the second air guiding guide element 222 is configured as four second air guiding guide openings, wherein the four air guiding guide openings each have an opening that is at least partially annular. In this embodiment, the first air guiding guide element 220 and the second air guiding guide element 222 are configured integrally with the transmission housing 166, see also. Figure 4a and Figure 4bFurthermore, here, the first connecting element 168 additionally forms a first air-conducting guide element 220. Furthermore, here, the second connecting element 170 additionally forms a second air-conducting guide element 222. Thus, here, the first air-conducting guide element 220 is integral with the first connecting element 168, and the second air-conducting guide element 222 is integral with the second connecting element 170.

[0111] Figure 3 A second longitudinal section of the air compressing device 100 is shown. The air guiding device 200 includes two further air guiding elements 212, which are configured here as air guiding strips. The further air guiding elements 212 guide the second partial air flow 194 from the electric motor 140 to the compressor device 120 for cooling. In this embodiment, the further air guiding elements 212 are configured by the elongated housing 110 and are arranged at the electric motor 140. Furthermore, once the electric motor 140 is set into rotation, the electric motor 140 generates another air flow 196 using the fan wheel 146. The air guiding device 200 is additionally configured to guide the further air flow 196 from the electric motor 140 to the compressor device 120 for cooling using the further air guiding elements 212.

[0112] In order to enable the electric motor 140 to generate a further air flow 196 , the elongated housing 110 comprises a further air inlet opening 116 , see also Figure 5b Air can flow into the elongated housing 110 through the further air inlet opening 116 and form a further air flow 196. Furthermore, the further air flow 196 can flow out of the air outlet opening 118. Two further air inlet openings 116 are provided here, which have an annular shape at least in sections.

[0113] Figure 4a A perspective view of the transmission 160 of the air compression device 100 is shown. The air guiding device 200 includes an air guiding element 210. In this embodiment, the air guiding element 210 is configured as a transmission cover 214 of the transmission 160. The transmission cover 214 is connected to the transmission housing 166 in a form-locking manner. In this embodiment, the transmission cover 214 is configured in the form of a disk. The transmission cover 214 also includes an air guide hood 216. In this embodiment, the air guide hood 216 is integral with the transmission cover 214.

[0114] In addition, the air guide device 200 here includes three air guide openings 202. The air guide openings 202 guide the air flow 190 from the energy supply device 180 into the transmission 160. In this embodiment, the air guide openings 202 are at least partially oval. In addition, the air guide openings 202 are each configured as an opening 167 in the transmission housing 166.

[0117] Figure 5a An exploded view of the housing 110 of the air compressing device 100 is shown. The housing 110 is elongated. Furthermore, the elongated housing 110 is wedge-shaped. The elongated housing 110 comprises an upper housing shell 500, a lower housing shell 502, a first housing side shell 504, and a second housing side shell 506. The elongated housing 110 is configured so that the visible fastening elements of the elongated housing 110 are essentially invisible to the user when using the air compressing device 100.
