Particle receiving device, arrangement and method for operating an arrangement

A method for operating an arrangement comprising a particle outlet of a vacuum cleaner and/or of a cyclone separator, the particle outlet comprising a particle outlet opening, the arrangement further comprising a first particle receiving device for attachment to the particle outlet and for receiving separated particles, the first particle receiving device comprising a first particle receiving volume for receiving the particles, a first access element with a first access element opening through which the particles can be transported into the first particle receiving volume, and a first closure element, wherein the first access element can be selectively displaced relative to the first closure element into a closure position, in which the first closure element closes the first access element opening, or into an open position, in which the first closure element releases the first access element opening, wherein the arrangement further comprises a second particle receiving device with a second closure element and with a second access element which comprises a second access element opening, wherein the second access element can be selectively brought into an open position or a closure position, wherein in the closure position the second access element opening is closed by the second closure element, the method comprising the steps:

• attaching the first particle receiving device to the particle outlet, wherein the first access element is situated in the closure position,
• bringing the first access element into the open position,
• transporting the particles into the first particle receiving volume,
• attaching the second particle receiving device to the particle outlet, wherein the second access element is situated in the closure position,
• together bringing the first access element into the closure position and the second access element into the open position, wherein the particle receiving volumes are closed with respect to the environment,
• removing the first particle receiving device from the particle outlet, wherein the first particle receiving volume remains closed with respect to the environment.

An arrangement comprising a particle outlet of a vacuum cleaner and/or of a cyclone separator, the particle outlet comprising a particle outlet opening, the arrangement further comprising a particle receiving device for receiving separated particles, the particle receiving device being attached to the particle outlet and comprising:

• a particle receiving volume for receiving the particles,
• an access element with an access element opening through which the particles can be transported into the particle receiving volume, and
• a closure element,
• wherein the access element can be selectively displaced relative to the closure element into a closure position, in which the closure element closes the access element opening, or into an open position, in which the closure element releases the access element opening, wherein
• the particle receiving device is a first particle receiving device and the arrangement further comprises a second particle receiving device with a second closure element and with a second access element which comprises a second access element opening, wherein the second access element can be selectively brought into an open position or a closure position, wherein in the closure position the second access element opening is closed by the second closure element, wherein
• the first access element and the second access element together as a group can be selectively brought into a first position or a second position, wherein in the first position the first access element is in the open position and the second access element in the closure position, and in the second position the first access element is in the closure position and the second access element in the open position.
