Description

Power-free blowing device

The invention relates to a power-free air blowing device, in particular, a user can press and pull a telescopic air bag with a foot, thereby inflating or deflating the telescopic air bag, and letting the leaked gas blow the user through the flexible pipe body to achieve the air cooling. And no power consumption.

The air blowers used by the general public are common electric fans, but the electric fans still accumulate considerable power consumption after long-term use, and today's environmental green energy awareness raises the way, how to improve the efficiency of electrical appliances to reduce electrical appliances The power consumption of supplies has always been the focus of manufacturers' improvement. How to reduce the power consumption of electric fans, even if there is no need to use electricity, can have the effect of cooling and cooling, which is the place where such goods can be improved.
In addition, the Republic of China New Patent Announcement No. M380997 "Infrared Thermal Induction Fan" is a type that automatically activates a fan according to indoor temperature and personnel position and tracks and positions the person. We use the combination of stepper motor and embedded chip to make the signal received by temperature-controlled thermal induction to change the direction of rotation of the electric fan, instead of the traditional electric fan can only rotate in a fixed form, the system can make the electric fan Automatically can sense the direction of the person, and the indoor temperature rises or falls. The fan will automatically switch the switch to make the electric appliance more humanized and scientific in the future, in order to achieve convenience.
The above case is to switch the opening and closing of the fan by infrared sensing to achieve energy saving effect. Although it does not directly improve the efficiency of the fan to reduce its power consumption, it can avoid being caused by people not in the vicinity of the fan. Power consumption, but the above case still needs electricity to start, if the power is used, it will consume electricity, and it can not achieve the power without cooling, can achieve the effect of air cooling.

Accordingly, in view of the above-mentioned shortcomings, the present invention provides a power-free blowing device, which comprises a compression airbag, and a closed airtight space is formed therein, and the compression airbag is provided with an inlet and an outlet respectively connected. To the airtight space; a first one-way valve is disposed on the inlet of the compression airbag; at least one flexible pipe body is disposed on the outlet of the compression airbag; and a tensioning element is disposed on the compression The top of the airbag.
A second one-way valve is disposed between the outlet of the compression airbag and the flexible pipe body.
The first check valve described above is an air valve that can only enter and exit, and the second check valve is a gas valve that is only inaccessible.
The flexible pipe body is provided with a regulating valve.
The invention has the following effects:
1. The invention can achieve the effect of blowing and cooling without using extra power, so that it has the structure of energy saving and environmental protection.
2. The present invention can slowly blow out the gas stored in the compression airbag, and the user does not need to retract the compression airbag all the time.
3. The invention is easy to carry and use, and the function of blowing can be used without additional power supply.
4. When the invention is not used as a blowing device, it can also be used as a footrest for a chair, allowing the user to rest more comfortably on the chair.

First, referring to the first, second and third figures, the present invention is a power-free blowing device comprising a compression airbag (1), a first one-way valve (2), and a flexible a pipe body (4), a tensioning element (5) and a regulating valve (6), wherein:
The compression airbag (1) has a closed airtight space (11) formed therein, and an inlet (12) and an outlet (13) are respectively connected to the airtight space (11) at the top of the compression airbag (1).
The first check valve (2) is disposed on the inlet (12) of the compression air bag (1), and the first check valve (2) is an air valve that is only inaccessible.
The flexible pipe body (4) is disposed at the outlet (13) of the compression air bag (1).
The pressing and pressing member (5) is disposed on the top of the compression airbag (1), and the tensioning and pressing member (5) can be used as a lifting handle for carrying it anywhere.
The regulating valve (6) is disposed on the flexible pipe body (4).
Further, a second check valve (3) is added between the outlet (12) of the compression airbag (1) and the flexible pipe body (4), and the second check valve (3) is only inaccessible. Air valve.
When in use, as shown in the fourth figure, the user (A) lies on the chair (B), places the foot (C) above the compression airbag (1), and then puts the foot (C) into the pull. Pressing element (5), the user pulls the tensioning element (5) by using the foot (C), further driving the compression airbag (1) to inflate, or placing the foot (C) across the compression airbag ( 1) The compressed airbag (1) is compressed by the weight of the foot (C), the gas in the compressed airbag (1) is blown out through the flexible tubular body (4), and the user (A) can apply the flexible tube The body (4) is pulled around the user (A), and the amount of gas blown by the compression airbag (1) through the flexible pipe body (4) is adjusted by the regulating valve (6), and is passed through the flexible pipe body (4). The blown gas can be directly blown to the user (A) to cool the body part to achieve the function of cooling and cooling, and the regulating valve (6) can adjust the amount of gas blown through the flexible pipe body (4), so The compressed air bag (1) will slowly discharge the stored gas, and the user (A) can blow the breeze for a long time without continuously pulling back or pressing the compressed air bag (1).
It should be noted that when the compression airbag (1) is inflated, as shown in the fifth figure, the user pulls the foot (C) penetrating the tensioning and pressing member (5) upwards (see the third figure). After the compression airbag (1) is deformed, the internal pressure of the compression airbag (1) is smaller than the external pressure, so that the outside air flows into the airtight space of the compression airbag (1) via the first check valve (2). (11) Since the first check valve (2) is a one-way air valve that can only enter, the incoming gas is stored in the airtight space (11) of the compression airbag (1) without The outside world is scattered.
When the compressed airbag (1) is deflated, as shown in the sixth figure, the user places the foot (C) on the compression airbag (1), and compresses the compression airbag (1) by the weight of the foot (C). After the compression airbag (1) is pressed, the gas stored in the airtight space (11) immediately flows out from the second check valve (2), and the gas is blown to the user via the flexible pipe body (4). Surrounding, the regulating valve (6) on the flexible pipe body (4) can adjust the amount of gas flowing through the flexible pipe body (4), so that the air cooling effect can be achieved and the power can be completely consumed without any power. energy saving.
When the airbag (1) is compressed as a foot pad, as shown in the seventh figure, the user (A) lies on the seat (B), and the user (A) can raise the compression airbag (1) to an appropriate height, and then When the regulating valve (6) is closed, the user can straighten the foot (C) and place it above the compression airbag (1). At this time, the compression airbag (1) will be closed due to the closing of the regulating valve (6). In operation, the user (A) can use the compression airbag (1) as a foot pad to allow the user (A) to lie flat on the seat (B) more comfortably.
According to a third embodiment of the present invention, as shown in the eighth figure, the compression airbag (1A) can be additionally provided with two outlets (not shown), and the outlet is provided with a second one-way valve (3A). The second check valve (3A) is provided with a flexible pipe body (4A), and the gas stored in the compression air bag (1A) flows through the flexible pipe body (4A) and the regulating valve (6A), and so on. Two or more flexible tubes (4A) can be blown to different parts of the body for better hair cooling.
