Abstract: The present invention discloses an aroma-type ventilation tube, which may be externally connected to an air source and blows an aroma gas, and a structure of the aroma-type ventilation tube includes a tube body, a ventilation passage arranged inside the tube body, and the like. The tube body mainly includes an aroma base, an aroma cartridge placed in the aroma base, and an aroma replaceably placed in the aroma cartridge. An aroma diffusion hole is provided on the aroma base, and an aroma ventilation hole is provided on the aroma cartridge. In this way, with rotation of the aroma cartridge in the aroma base, the aroma ventilation hole and the aroma diffusion hole are caused to be staggered or overlapped, so that the aroma gas released by the aroma cannot enter the ventilation passage or is released sequentially through the aroma ventilation hole and the aroma diffusion hole to the air passing through the ventilation passage.

Abstract: The present invention discloses an easy-to-clean vacuum cleaner, of which a structure includes a body, a dust suction port, a dust suction motor, a dust chamber, a dust discharge port, a dust discharge cover, and that like. The dust suction motor operates to suck and store garbage at the dust suction port in the dust chamber, which mainly means that a cleaning rack is arranged in the dust chamber, so that when the dust discharge port is exposed through the dust discharge cover, the cleaning rack can drive the garbage to be directly cleaned out of the dust chamber as long as the cleaning rack is taken out from the dust discharge port. Therefore, some garbage is light in weight, for example, light-weight hair-like flocs included in garbage sucked in a dust chamber of a pet vacuum cleaner for combing and cleaning hair of a pet can also be cleaned simply, conveniently, and quickly through the cleaning rack.

Abstract: The present invention discloses a handheld vacuum cleaner for pets, including a body, a charging base, a dust suction port, a cleaning accessory, and the like. A trigger is arranged on the body on a side of the dust suction port, and a driving member is arranged in the cleaning accessory. When the cleaning accessory is inserted into the dust suction port, the driving member can be brought into contact with the trigger, and the driving member can be driven by a pressing operation of the trigger to perform hair removal on the cleaning accessory. With this structure, a user can simultaneously perform grooming and dust suction and remove hair adhering to the cleaning accessory by holding the body with a single hand, which is simpler and more labor-saving in use. Moreover, the internally mounted driving member also makes the entire cleaning accessory compact and aesthetic in appearance.
