A portable blower assembly includes a cylinder that has an exhaust port integrated into the cylinder. A handle extends around the cylinder and the handle can be gripped by a user for directing the exhaust port toward a vehicle. A blower is rotatably integrated into the cylinder to urge air outwardly through the exhaust port thereby facilitating the air to be directed onto the vehicle for drying the vehicle when the blower is turned on. A heater is integrated into the cylinder such that the heater is in thermal communication with an interior of the cylinder. The heater is positioned between the blower and the exhaust port to heat the air is blown by the blower for enhancing drying the vehicle.

A system for cooling a circuit component on an electronic device includes a closed-loop cooling circuit and a coolant filling device. The closed-loop cooling circuit includes a coolant block, a first pump and a radiator. The coolant filling device includes a container, a base and a second pump disposed inside the base. The coolant filling device is configured for attachment to the cooling circuit. In some embodiments, when the coolant filling device is attached to the cooling circuit, coolant may be circulated from the coolant filling device to the cooling circuit while the cooling circuit circulates coolant. In further embodiments, when the coolant filling device is attached to the cooling circuit, coolant may be circulated from the coolant filling device to the cooling circuit while the electronic device remains powered on.

A blower unit for a portable handheld blower apparatus has a housing section and a tubular receiving space, formed in the housing section, with a first axial end and a second axial end and with a longitudinal center axis. Arranged in the receiving space of the housing section is an axial blower for generating a blower air flow, the axial blower being driven by a drive motor. The receiving space has an intake opening at its first axial end and a discharge opening at its second axial end. In order to reduce operating noise, an air guide plate is arranged at an axial distance in front of the intake opening, the air guide plate having external dimensions that are greater than the external dimensions of the intake opening. An annular gap that supplies intake air is formed between the air guide plate and an outer periphery of the housing section.

A clip-on fan includes a specialized clamping clip that is attached to rectangular or cylindrical tent poles that are commonly used for grow tents; wherein fans are essential components for growing in tents and the current designs clip-on fans do not meet the needs of indoor growers; the clip-on fan comprising a fan assemblage and clip clasp assemblage arranged at the base of the complete product, wherein the clip is able to grasp to the vertical tubular structure of a grow tent; the grasping clasp assembly consisting of: a left clip plate, a right clip plate, a clip plate rotation shaft, a clip spring, a fan connection hole and, a clip clamp opening; the left and right clip plates are connected in a bilateral symmetry through the clip plate rotation shaft at the central connection position.

The present disclosure relates to air assemblies having an inflation, a deflation, and a closed state for use with inflatable products, such as air mattresses. Specifically, the present disclosure relates to air assemblies where the configuration of the air assembly can be changed manually by a user by operating a directional control valve to inflate, deflate, or close the inflatable product. The directional control valve may also activate a pump in the inflation and deflation states and deactivate the pump in the closed state.

An electric component mounting unit for an air-conditioned garment, which is used in combination with a garment body having a fan opening and which is mounted on a body, includes a fan which takes air from outside into the garment body, a mounter which mounts the fan on the body, and a fan attacher which attaches the fan to the mounter. The fan includes a fan-side linker which links the fan with the fan opening.

A ventilator includes a ventilation body, the ventilation body includes a ventilation cavity and an air inlet end and an air outlet end communicating with the ventilation cavity, the ventilation body further includes an annular shell configured to form the ventilation cavity, the annular shell is formed with an annular cavity inside, an air inlet and an air outlet communicating with the annular cavity are disposed on the annular shell, the air outlet is communicated with the annular cavity and the ventilation cavity, the air outlet has a slit shape extending along a circumferential direction of the annular shell and is disposed to be capable to guide gas flows out towards the air outlet end. The ventilator may greatly increase the ventilation volume and the gas pressure, by using the ventilation body as mentioned above.

A debris blower (1) is disclosed comprising a fan housing (3), a fan (5) configured to generate an airflow through the fan housing (3), an electric motor (7) configured to power the fan (5), and a first battery accommodation space (9) configured to accommodate a battery unit (10) for supply of electricity to the electric motor (7). The debris blower (1) further comprises a first air cooling channel (11) fluidly connecting the first battery accommodation space (9) and the fan housing (3).

An air pump is provided, the air pump comprising: an air pump housing; a first check valve; a main air pump; an airway switching device; an air-supplementing pump; an air pressure sensor; and a control device. The control device is electrically connected to the main air pump, the airway switching device, the air-supplementing pump, and the air pressure sensor, and is configured to: send a main air pump stop signal based on the air pressure sensor detecting a threshold pressure in the inflatable body during operation of the main air pump; and send an air-supplementing pump operation signal based on the air pressure sensor detecting a pressure lower than the threshold pressure in the inflatable body when the main air pump is not in operation.

A neck fan includes an arc-shaped shell configured to hang around user's neck and at least four fan assemblies arranged in the shell. The shell includes a first part and a second part. Each of the first part and the second part defines an accommodating space, air inlets and air outlets communicated with the accommodating space, at least one partition is arranged in the accommodating space and configured to divide the accommodating space into at least two accommodating parts arranged along an extension direction of the shell. Each of the fan assemblies is arranged in one of the at least two accommodating parts and is configured to direct air into the one of the at least two accommodating parts through corresponding air inlets and to direct air out of the one of the at least two accommodating parts through corresponding air outlets.
