Disclosed is a dust collector using fan heat, comprising a bottom shell (10) and an upper cover (50), wherein a rear end (12) of the bottom shell (10) is provided with an air outlet (122) and a fan assembly (30), the upper cover (50) covers and is connected to the bottom shell (10), air flow from the fan assembly (30) is discharged via the air outlet (122), and the fan assembly (30) is provided with a fan (33) and a stator (331); and the rear end (12) is provided with a lower frame edge (121), the fan assembly (30) and the air outlet (122) are enclosed to form a closed air flow channel (35), and a heat collector (40) is provided on the stator (331) in the air flow channel (35), and can rapidly collect heat and warm the air flow to form hot air flow. Also disclosed is a dust collector having an ironing function, which uses hot air flow to heat an ironing board (60) and then performs ironing and sterilization, so that the dust collector also implements recycling of energy resources while achieving the dust collection effect so as to perform effective sterilization and ironing.

The present disclosure relates to a hand-held vacuum cleaner (100), comprising a housing (1), a dust cup (2) and an electrical motor (3). The housing (1) is provided with an air inlet (111), an air outlet (311) and an air blowing vent (121), and the air blowing vent (121) is disposed adjacent to the air inlet (111). The dust cup (2) is disposed to the housing (1), and the dust cup (2) is connected to the air inlet (111). The electrical motor (3) is provided with an electrical motor chamber (31), airflow from the air inlet (111) switchably flows out through at least one of the air outlet (311) and the air blowing vent (121) by means of a switching mechanism (4) after flowing through the dust cup (2) and the electrical motor (3).

A backpack blower includes a motorized blower unit driven by an engine mounted to a frame having straps to be supported by a user's shoulders and having an air discharge pipe with openings which allow a portion of the air discharge to blow out onto a wearer's neck, head, and/or body. A deflector can further be added to direct the air discharge and the deflector can be adjustable. One or both of the deflector and openings can include a control device which allows for flow through the opening or deflector to be stopped or the volumetric flow rate of air passing there-through can be adjusted.

Disclosed are exhaust heat recirculation systems for vehicle wash vacuums, methods for making/using such vacuum exhaust heat recirculation systems, and vehicle wash facilities with a central vacuum system having exhaust recirculation capabilities. A vehicle wash facility includes multiple vehicle stalls, and a vacuum system for removing debris from vehicles at the vehicle stalls. The vacuum system includes vacuum hoses mounted at the vehicle stalls, a central power unit that generates vacuum pressure for operating the hoses, and feeders for connecting the hoses to an inlet manifold of the central power unit. An exhaust heat recirculation system is operatively connected to and evacuates exhaust gases from the central power unit. The vacuum system may include a continuous-belt heater unit that receives the evacuated exhaust gases and repurposes the gas for drying towels, mitter cloth strips, brushes, etc.

A pet grooming machine and a method for pet hair grooming is provided. The pet grooming machine includes a blower having a blower air-inlet, a motor unit, a blower air-outlet, and an air channel, a tank unit having a tank, a tank air-inlet, a filter, and an air-outlet. The blower and tank unit can be in either separated configuration or combined configuration. In separated configuration, the blower is separated from the tank unit and can be independently used for blowing. In combined configuration, the blower air-inlet and the tank unit are detachably combined and sealed. In combined configuration, the negative pressure generated by airflow driven by the blower is transmitted to the tank air-inlet through the tank and the filter. The blower is a portable blower, which can be held with one hand by the user for prolonged blowing on the pet without need for an external flexible hose.

Provided is a cleaning device including a vacuum cleaner including a dust collector into which dirt and dust is collected, a docking station connected to the dust collector and having a long axis extending in a first direction, and the docking station includes a docking part coupled to the dust collector to remove dirt and dust collected in the dust collector, a sucking device sucking up the dirt and dust and inside air in the dust collector docked with the docking part through the docking part, and a circulation duct arranged for the air sucked up by the sucking device to be circulated to the docking part.

A surface cleaning device includes a nozzle and an odor dial assembly. The nozzle includes a nozzle housing and a dirty air passageway. The odor dial assembly include a fragrance member and a dial body configured to be removably coupled to the nozzle housing. The dial body at least partially defines a fragrance cavity configured to at least partially receive the fragrance member and a fragrance passageway extending therethrough. The odor dial assembly is configured to transition between a plurality of user-selectable positions to adjust an amount of fragrance particles released by the fragrance member into the dirty air passageway.
