Embodiment 2

[0052] On the basis of embodiment 1, see image 3 as well as Figure 4 , the fan 4 comprises a DC motor 45, a base 46, a fan shaft 42 and a fan controller 47; the DC motor 45 and the fan controller 47 are placed on the base 46 respectively; The other end of the fan shaft 42 is provided with a fan impeller 41; the coupling 44 and the outside of the fan shaft 42 are fixed by a fixed flange 43; the control board 1 is connected with the fan controller 47, supplies power to the fan 4 and controls the fan impeller 41 Rotational wind speed; the air outlet 10 communicates with the fan impeller 41 .

[0053] see Figure 5 , when the present embodiment is implemented, the wiring between the parts is that the charger 2, the storage battery 3, the power indicator light (control button 6) and the fan controller 47 are connected to each other by red and black two strands of wires, and the charger 2. Connect to the 220V AC power socket to charge the battery 3. An air switch is set between...

Embodiment 3

[0070] On the basis of Embodiment 2, a first air outlet and a second air outlet are arranged at the bottom of the fan 4, and a gas flow sensor and a pressure transmitter are arranged on the first air outlet. A temperature sensor is set on the casing of the DC motor 45 .

[0071] Both the first air outlet and the second air outlet are tubular; and one end is fixed on the bottom of the fan 4 . During implementation, the diameters of the first air inlet and the first air outlet are both Φ50mm; the diameter of the second air inlet is also Φ50mm, and the diameter of the second air outlet is Φ20mm, which is convenient for connecting with the inflated equipment.

[0072] Preferably, the model of the gas flow sensor is HFS4001, MF5000 or FS4008. These gas flow sensors are small in size and can monitor the air outlet flow through the first air outlet in real time, which is convenient for calculating the instantaneous and cumulative flow of the air outlet at the air outlet. The control...

Abstract

The invention belongs to the technical field of gas charging and discharging devices, and relates to a portable type gas charging and discharging device. The portable type gas charging and dischargingdevice comprises a case as well as a control assembly and a fan which are arranged in the case, wherein the fan comprises a direct-current motor, a base, a fan shaft, a fixed flange, a shaft couplerand a fan controller; the direct-current motor and the fan controller are separately arranged on the base; the working end of the direct-current motor is connected to one end of the fan shaft throughthe shaft coupler and the fixed flange; the other end of the fan shaft is provided with a fan impeller; and the control assembly is connected to the fan controller for supplying power to a fan for controlling rotation air speed of the fan impeller. The direct-current motor in a high-pressure vortex fan is changed into the direct-current motor, so that charging, power storage, control, display andthe fan are integrally arranged; and the portable type gas charging and discharging device is small in size, is small in weight, is strong in power, is good in stability, and uses charging equipment to safely supply power under a no-power case.

Description

technical field [0001] The invention belongs to the technical field of inflation devices, in particular to a portable inflation and deflation device. Background technique [0002] At present, the commonly used inflation and deflation equipment adopts mechanical inflation and deflation devices and electric inflation and deflation devices. The mechanical inflation and deflation devices draw air into the storage part by means of pulling, and then inject or replenish inflation by pushing. The air required by the device is the opposite when deflated. This kind of inflation and deflation device has a small inflation volume and uncontrollable air volume. It is manually operated, which is inefficient, wastes physical strength, and is inconvenient to carry; while the electric inflation and deflation device does not require manual inflation. Operation, only need to connect to the power supply of different specifications, you can start the equipment, control the fan to inflate and defl...
