Abstract: The invention employs blades featuring multiple holes. The metal decoration for coupling conceals perforated sections, which ease the mounting and alignment for screws installation. The blade holder incorporates two or more slots for screws to slide through the decoration cover, securing the blade assembly onto the fan motor for assembly and operation. The decoration cover has a minimum of two holes for alignment screw installation and one hole for preassembling and fastening it onto the blade. Alignment screws serve a dual purpose by sliding into the blade holder's slots and installing the blade assembly. This not only aligns the blade holder but also temporarily holds the assembly, freeing the installer's hands for subsequent installation steps. This simplifies the process, minimizes installer fatigue and allowing the use of both hands to handle screws, making it a time-efficient and straightforward task. The installation difficulty then reduces from 9 to 1.

Abstract: Disclosed are a flexible pipe and a manufacturing method thereof. The flexible pipe includes an outer bellows formed in a corrugated tubular shape with mountains and valleys, an inner bellows formed in a corrugated tubular shape with mountains and valleys and provided inside the outer bellows, a pair of flanges connected to both ends of the outer bellows and the inner bellows, respectively, and a detection unit for checking whether leakage occurs due to damage or breakage of the outer and inner bellows by detecting an amount of oxygen present in an air having an atmospheric pressure and filled in an atmospheric space between the outer and inner bellows. Leakage due to damage or breakage of the outer and inner bellows can be detected based on variation in the amount of oxygen present in the space between the outer bellows and the inner bellows.

Abstract: A bellows having tweezers-shaped corrugated portions for increasing resistance and restoring force against torsion includes: a first flat part having a flat cylindrical shape; a second flat part having a flat cylindrical shape and disposed opposite to the first flat part; and a plurality of corrugated portions, each having a tweezers shape and disposed between the first flat part and the second flat part, wherein each of the plurality of corrugated portions is sequentially connected to each other, so as to increase resistance and restoring force against torsion.

Within the housing and the casings, there are provided two sets of a wheel control device, a temperature limiting thermostat, a circuit board for switch control, a mechanical fan for drawing cold air in and expelling hot air out, a main circuit board configured to activate heating and agitation; a drive source for agitation and testing, a support for heating member, an electric heating member, a fan blade assembly, and an inlet device. The circulation cooking device can mounted on a large container by a seat for single container or two small containers by a seat for double container.

Abstract: A sous-vide circulator cooker includes a casing including a front shell and a rear shell; a wheel control device, a temperature limiting thermostat, a circuit board for controlling switch, a mechanical fan for drawing cold air in and expelling hot air out, a main circuit board configured to activate heating and agitation; a drive source for agitation and testing, a support for heating member, an electric heating member, a fan blade assembly, a lower case section configured to store a quantity of liquid which is configured to be agitate by the fan blade assembly, an inlet device including, a fastening assembly, and an AC power cord for supplying power to electrical components of the circulator cooker.

Abstract: A folding electrically powered vehicle includes a handlebar unit mounted at an upper end of a stem; a front wheel; an inverted U-shaped front suspension assembly including an intermediate joint pivotably mounted on a lower portion of the stem, a rearward curved frame member, and two foot rests; a front frame having two ends of a front portion pivotably secured to the two ends of the suspension assembly, the front frame including two rearward extending bars; a rear frame including two side bars pivotably secured to the rearward extending bars, two rear wheels, and a stop tube across front portions of the side bars; a seat assembly including two bottom tubes pivotably secured to two ends of the rearward extending bars respectively, and a pivotal seat back; and two shock absorbers each pivotably secured to the seat assembly and the rear frame.

Abstract: A foldable electric vehicle includes a front frame including two side mounts; a front foot rest including two mounting members and a rear hole; a rear foot rest including two mounting members, a front pivotal board, and a spring biased lock pin locked in the hole; a rear pedestal including two mount elements, two chair supports, and a top hook; hinges for connecting the front frame and the front foot rest, connecting the front foot rest and the rear foot rest, and the rear foot rest and the pedestal; two front links each pivotably secured to the side mount and the mounting member; two rear links each pivotably secured to the mount element and the mounting member; a chair including a transverse rod and a spring biased lock rod locked in the hook; and two sets of two pivotal bars pivotably connected to chair supports and the chair.

Abstract: A combination cooling and heating device is provided with a cooling fan including an outlet including a mouth; and a heater including a mouth member complimentarily connected to the mouth of the outlet of the cooling fan, an indicator, a shell member including heating elements, a blade assembly, a micro switch, a spring biased trigger member, a front louver, and a frame secured to both the louver and the shell member. The trigger member is attached to the micro switch. The blade assembly is rotatably secured to the trigger member. In a heating operation, the fan activates to produce airflow which rotates the blade assembly, the blade assembly rotates to pull the trigger member, and the trigger member turns on the micro switch which activates the heating elements, thereby taking heat generated by the heating elements out of the louver.

Abstract: A portable misting fan is provided with a housing; a fluid reservoir including an externally threaded neck; an internally threaded connecting ring secured to the neck; a battery powered fan motor in the housing; fan blades; a first switch on the housing for turning on or off the fan motor; a battery powered pump motor in the housing; a pump driven by the pump motor; a fluid outlet port on the pump; a hose having one end secured to the fluid outlet port; an atomizing head on the housing and secured to the other end of the hose; a fluid inlet tube; a second switch on the housing for turning on or off the pump motor; and a fluid tube having one end secured to the fluid inlet tube and an other end terminates in the fluid reservoir. Fin mist can be generated by the misting fan.
