Abstract: A portable hand warmer charging case includes a case body. A placement chamber configured to place a hand warmer unit for charging is provided on the case body. The case body is provided with a first circuit board, a first charging unit, and a first battery. The first battery and the first charging unit are electrically connected to the first circuit board. When the hand warmer unit is placed in the placement chamber, the first circuit board is configured to output electrical energy, which is output by the first battery, from the first charging unit; and the first charging unit is configured to be adapted to a second charging unit on the hand warmer unit for use and transmit the electrical energy output by the first circuit board to the second charging unit on the hand warmer unit.

Abstract: The present disclosure provides a neck fan. The neck fan includes a hanging shell and a first fan assembly. The hanging shell includes an inner end portion that is in contact with the neck. A first air guide chamber having a first central axis is arranged on the hanging shell in a protruding manner. The first air guide chamber includes a first air inlet arranged at a lower end portion of the hanging shell and a first air outlet opposite to the first air inlet. The first air outlet is oriented towards the inner end portion. Both the first air inlet and the first air outlet are located on the first central axis. The first fan assembly is located in the first air guide chamber. And the first fan assembly is configured to drive an air flow to flow from the first air inlet to the first air outlet.

Abstract: A stepless regulation fan includes a fan main body and a control circuit board. The fan main body is equipped with first motors and fan blades connected to the first motors. The control circuit board includes an MCU, a stepless regulation element and a first driving circuit. The stepless regulation element and the first driving circuit are electrically connected to the MCU. The stepless regulation element is used for user operation, and the first driving circuit is electrically connected to the first motors. When the stepless regulation element is operated, a stepless regulation signal within a preset regulation range is fed back to the MCU. Based on the stepless regulation signal, the MCU outputs a rotating speed control signal corresponding to the stepless regulation signal to the first driving circuit. The first driving circuit adjusts driving power output to the first motors based on the rotating speed control signal.

Abstract: A bracket assembly and a fan with a bracket assembly include: an installation bracket, the installation bracket being equipped with an installation part; and at least one bendable and shapeable supporting leg, the supporting leg being connected to the installation part. Therefore, users can connect the installation bracket to an external device, thereby attaching the bendable and shapeable supporting leg to the external device, so that the external device can be suspended or supported on an external object through the bendable and shapeable supporting leg. At the same time, a support angle of the supporting leg can be adjusted by bending the supporting leg to adjust an angle of the external device. Moreover, a total number of the supporting legs can be set to 3-10, so that the supporting legs can be combined with each other to form an octopus shape to provide stable support.

Abstract: A portable fan includes a housing, an air blowing assembly, a power supply assembly and a mounting shell. The housing is provided with a first air inlet, an air outlet and a first air guide chamber. The air blowing assembly is configured to drive an air flow to flow from the first air inlet to the air outlet. The power supply assembly is electrically connected to the air blowing assembly to supply power to the air blowing assembly. The mounting shell is connected to the housing. The mounting shell includes a first mounting part and a second mounting part. The first mounting part is integrally formed with the second mounting part. The first mounting part is configured to mount the air blowing assembly and the second mounting part is configured to mount the power supply assembly.

Abstract: A multifunctional fixed bracket includes a bracket body and a first supporting body. The bracket body is provided with an accommodating chamber. The accommodating chamber is configured to place a container. The first supporting body is connected to the bracket body, and the first supporting body is configured to hang items. Through the above structure, since the bracket body is provided with the accommodating chamber, a user can place a container such as a water glass, a beverage bottle, and an umbrella into the accommodating chamber, and can hang an item such as a key, an earphone, a bag, and a garbage bag on a first supporting member at a bottom of the bracket body, fully using a space of the fixed bracket, increasing the versatility of the bracket, and allowing the user to store various items on one fixed bracket, thereby improving the space utilization rate and cleanliness.
