An oronasal pad (1), comprising a nasal structure (2) and an oral structure (3) that are connected to each other. A through cavity (6) is formed inside the nasal structure (2) and oral structure (3). The cavity (6) can receive pressurized gas. The nasal structure (2) fits around a wearer's nostrils to seal. The oral structure (3) fits around the wearer's mouth to seal. The nasal structure (2) is configured to not pinched against the wearer's nose when sealed against the wearer's nose base by means of pressurized gas. The oral structure (3) is configured to accommodate and fit around the wearer's mouth in response to the oronasal pad (1) being put on by the wearer. The oral structure (3) comprises an oral soft pad (32) in contact with the wearer's face and a reinforcing structure (4) connected to the oral soft pad (32). The rigidity of the reinforcing structure (4) is greater than the rigidity of the oral soft pad (32).

The present disclosure disclosed a brake apparatus, a wheel body assembly and a rollator. The brake apparatus comprises a shaft body, a housing, a magnetic induction mechanism, a rectifier mechanism and an adjustment mechanism, the housing is rotatable relative to the shaft body, the magnetic induction mechanism is used to generate resisting force opposite to a rotation direction of the housing or the shaft body by a magnetic field reaction when the housing rotating relative to the shaft body, the rectifier mechanism is used to rectify the current of the magnetic induction mechanism, the adjustment mechanism is used to adjust the magnitude of the resisting force generated by the magnetic induction mechanism. By setting the rectifier mechanism to rectify output of the multiple wires of the magnetic induction mechanism, the structure of the adjustment mechanism can be simplified, making the overall structure of the brake apparatus simpler, more compact and occupying less space. By setting the adjustment mechanism to automatically adjust resisting force, the brake apparatus can be applied to a wider range, and more intelligent.

Disclosed are a heat pump water heater coupled with a water system and a temperature control assembly. The temperature control assembly comprises a heat exchange unit, a heat exchanger, a water supply pipeline, a return water pipeline, a room temperature control apparatus, a heat pump water heater, a buffer water tank and a water pump. The heat pump water heater comprises a temperature rise water tank, a heat pump evaporator and a compressor. The heat pump evaporator is coupled to the return water pipeline or the water supply pipeline. In a coupled form, an outdoor unit of the heat pump water heater is replaced by the heat exchange unit by means of a circulating water body, so that a room temperature adjustment system shares the heat exchange unit with a hot water supply system, thereby saving space. Moreover, multiple households may share one heat exchange unit, which is of great significance for residential houses such as apartments and rental houses.

An object of the present invention is to provide a refrigerator oil composition which can effectively suppress an increase in an acid value even when a ratio of an unsaturated fluorinated hydrocarbon compound (HFO) in a refrigerant is increased. The problem is solved by making the refrigerator oil composition to be used for a refrigerant which contains one or more unsaturated fluorinated hydrocarbon compounds selected from compounds represented by general formula (1):         CxFyHz     (1) wherein x is an integer of 2 to 6, y is an integer of 1 to 11, and z is an integer of 1 to 11, and one or more carbon-carbon unsaturated bonds are present in the molecule, the refrigerator oil composition containing a base oil (A), and one or more silicone compounds (B) selected from the group consisting of an unmodified silicone (B1) and a modified silicone (B2), wherein a content of the silicone compound (B) is 0.05% by mass or more based on the total amount of the refrigerator oil composition.

A flow control circuit for an actuator is provided. The actuator comprises a first chamber (111) and a second chamber (112), wherein the first chamber experiences a volume change that is larger than a volume change experienced by the second chamber upon actuation of the actuator (110). The flow control circuit (10) comprises a first port (11) configured to be connected to the first chamber (111), a second port (12) configured to be connected to the second chamber (112), and a flow control valve assembly (20) comprising one or more valves configured to provide a flow of pressurized fluid from a pressurized fluid source (41) to one of the first and second ports (11, 12) along a fluid supply path and further configured to provide a flow of fluid from the other of the first and second ports (11, 12) to a fluid sink (42) along a fluid return path.
