Portable pump that wirelessly transmits air pressure data to mobile electronic devices and Its combination with mobile electronic devices

The invention mainly discloses a pump, in particular a portable pump capable of transmitting air pressure data to a mobile electronic device for viewing by a user using Bluetooth technology.

In the past, bicycles were only used in a form of use as a means of transportation. However, as the times continue to advance, as bicycles are gradually transformed into fashion sports fitness equipment, the forms and types of use are diversified, resulting in mountain bikes, street cars, sports cars, small-diameter cars, etc. Different models, and the unit price ranges from hundreds of dollars to tens of thousands of dollars. Therefore, in addition to being a kind of sports and fitness equipment, today's bicycles can become home furnishings. The pump used with the bicycle has also undergone great changes. The pump has different pressure requirements depending on the tires that are used in different models. Therefore, the pump must have a pressure gauge for viewing the pressure value. The type of pump is roughly divided into two types: ground-mounted pump and mini-inflator. In the case of a mini pump, in order to accommodate a conventional mechanical pressure gauge, the outer diameter of the pressure gauge must be larger than the outer diameter of the pump, which causes a sudden sense of the appearance of the pump. In order to avoid the sudden sensation of the overall design of the above-mentioned pump, the volume of the attached pressure gauge must be reduced as much as possible. Otherwise, the pressure gauge is too prominent, and the structure of the pump will result in no aesthetic and design ambiguity. However, this approach has spawned another problem, which is the digital scale and unit label of the pressure gauge (eg PSI, BAR, KPA and other pressure units are limited by the smaller pressure gauge volume, resulting in a variety of pressure gauges to meet a variety of units, and the number and scale must be relatively small size, making it very difficult for the user to interpret the pressure value. On the other hand, when pumping, the connection between the mini pump and the tire nozzle will cause the pressure gauge to be disturbed or blocked by the tire spokes, and the excessive pressure gauge will also make the pump and the tire nozzle difficult to connect. It is not easy to interpret pressure values. At the same time, when pumping, the pump will also be shaken by the force, which will cause difficulty in the interpretation of the pressure. This is undoubtedly a problem for the users who have presbyopia in the middle and young ages, and it is difficult to watch the pressure of the pumping.
