Abstract
Description
- The present application relates to inflation devices, and, in particular, to inflation devices utilizing a cooling fan as a blower.
- Inflation devices, or inflators, are used to inflate items such as vehicle and bicycle tires, air mattresses, and swimming flotation devices. In general, tires are compressed with air having a “high pressure, low volume,” while larger volume items, such as air mattresses and rafts, are inflated with air having a “low pressure, high volume.”
- Existing inflators often have a “compressor-type” structure. The inflator will include a motor assembly that has, at one end, a reciprocating piston and pump. The motor will drive the piston so that the piston will compress the air that enters the pump. The resulting air will be highly pressurized and suitable for the inflation of tires. The motor and reciprocating action of the piston, however, generally produce a great-deal of heat. One solution to prevent the inflator from overheating is to extend the motor's shaft at the end of the motor opposite the end that includes the piston and pump and attach a radial fan. U.S. Pat. No. 5,252,033 to Lin demonstrates such a configuration. In such compressor-type structures, the fan will “blow” air across the components in order to cool them. The air is then exhausted out of the inflator
- However, with such a configuration, some of the cooling air may disperse within the inflator and fail to be exhausted out of the inflator. The temperature of this air often will increase, thus resulting in an inefficient cooling system. In addition, the running fan itself may produce heat that fails to be exhausted, again resulting in inefficient cooling. Moreover, inefficient cooling may cause the inflator to increase in temperature to the point that it is “hot to the touch” and uncomfortable for a user.
- Furthermore, such compressor type-structures produce “compressed air” that is high pressure, low volume. As described above, while compressed air is suitable for inflating tires, it is generally unsuitable for inflating larger-volume items because of the large amount of time required for inflation. U.S. Pat. No. 4,829,625 to Wang discloses a vacuum/air compressor that provides both high volume, low pressure air compression and low volume, high pressure air compression. The high volume, low pressure compression is suitable for inflating larger-volume items while the low volume, high-pressure air compression is suitable for inflating high tires. The Wang patent, however, fails to provide a solution regarding any potential overheating of the vacuum/air compressor.
- An inflator is disclosed having a housing and a motor assembly within the housing. A first output line is in fluid communication with a first end of the motor assembly to provide a cooling path of air and a high-volume flow of air. The first output line provides a guiding path for the egress of the high-volume flow of air from the housing. A second output line is in fluid communication with a second end of the motor assembly and to provide a high-pressure flow of air.
- The present disclosure also describes a dual-pressure inflator that also includes a housing and a motor assembly within the housing. A centrifugal fan is attached to a first end of the motor assembly and creates an axial path of cooling air. A blower housing is attached to the housing, surrounds the centrifugal fan, and provides a guided path for a high-volume flow of air. A crankshaft, piston and cylinder are attached to a second end of the motor assembly and provide a high-pressure flow of air opposite the high volume flow of air. A detachable high pressure hose is attached to the cylinder and provides an egress for the high-pressure flow of air from the housing.
- The present disclosure also includes a process for operating an inflating mechanism. The process includes introducing the source of air into a housing. Additionally, the following are simultaneously created: a path of cooling air is created with a volute blowing mechanism; a high volume flow of air also is created with the volute blowing mechanism; and a high pressure path of air is created with a crankshaft, piston and pump cylinder.

FIG. 1 is a view of an inflator with the inflator housing partially cut away. -
FIG. 2 is an enlarged view of the inflator ofFIG. 1 that shows the flow path of cooling air. -
FIG. 3 is a top view of a fan and blower housing as shown inFIG. 1 . -
FIG. 4 is a side view of a fan and blower housing as shown inFIG. 1 . -
FIG. 5 is a view of a prior art compressor structure. - Before describing the novel inflator, a brief explanation of prior art compressor structures will be helpful. Referring to
FIG. 5 , traditional compressor structures, orinflators 100, utilize amotor 102 that drives acrankshaft 104 and a reciprocatingpiston 106. Upon moving in a downwardly direction, thepiston 106 will draw air into acavity 110 of thecylinder 108. Upon moving upwardly, thepiston 106 will compress the air, causing the air to be highly pressurized. The highly pressurized air will exit through anoutlet 112 and is suitable for inflating items that require a higher-pressure/low volume, such as tires. The high pressure/low volume air, however, is undesirable for inflating high volume items such as air mattresses, because it will take a long period of time to inflate such items. - During the operation of the inflator, the
motor 102 and reciprocatingpiston 106 generate heat that may become excessive. To solve this problem, the motor's shaft may be extended from a rear 114 of the motor (i.e., an end opposite the piston and cylinder), and aradial fan 116 may be attached. Thefan 116 generates air to cool the components. However, the operation of thefan 116 may generate heat, which can remain inside the inflator and cause the inflator to become hot to the touch and make a user operating the inflator uncomfortable. Moreover, the inflator may end up overheating. - Turning now to
FIGS. 1 and 2 , anovel inflator 2 for inflating items such as tires, air mattresses, swimming flotation devices and the like is shown and described herein. Notably, theinflator 2 is suitable for inflating items that require either high pressure/low volume or high volume/low pressure air flow. Theinflator 2 includes aninflator housing 4 and ahandle 6 that is contiguous with thehousing 4. Thehandle 6 can be molded contiguous with the housing and can be formed in a variety of shapes, such as a D-shape or an oblong shape, so that it is ergonomically advantageous when grasped by a user of theinflator 2. Preferably, theinflator housing 4 andhandle 6 are made of high-temperature plastic. - The
inflator 2 also includes aremovable battery housing 8 that houses abattery 10 in order to power the inflator. WhileFIG. 1 shows thebattery housing 8 attached to abottom wall 4A of theinflator housing 4, thebattery housing 8 may be attached at other portions of theinflator housing 4, depending on the shape of theinflator housing 4. The batteries can be single use or rechargeable. - An
air intake 9 is included that allows ambient air to enter into the housing that provides both high pressure and low pressure air as well as cooling air for components located within theinflator housing 4. While, in a preferred embodiment, theair intake 9 is located in aside wall 11 of thehandle 6, theair intake 9 can be located elsewhere depending on the configuration of theinflator housing 4 and associated components (described further below). - The
handle 6 is conventional and includes atrigger 13 that actuates amotor assembly 12 located within theinflator housing 4. Preferably, thehandle 6 includes a lock-onmember 18 that engages thetrigger 12 so that thetrigger 13 remains in an actuated position without requiring the user to “hold” thetrigger 13. - The
motor assembly 12 includes amotor 14 and agear case 16 attached to afirst end 14A of themotor 14. Thegear case 16 reduces the amount of speed generated by themotor 14. Depending on the amount of reduction desired, thegear case 16 can include a variety of configurations. However, in a preferred embodiment thegear case 16 includes apinion 20 andgear 22. - A
crankshaft 24,piston 26 andpump cylinder 28 are attached to thefirst end 14A of themotor assembly 14. Thegear case 16 reduces and transfers torque generated by themotor 14 to thecrankshaft 24, which, in turn, drives thepiston 26. Thepiston 26 compresses air within acavity 30 of thepump cylinder 28. The air, which enters theinflator housing 4 via theair intake 9, enters thecavity 30 of thepump cylinder 28 through aninlet 32. Once the air within thecavity 30 is compressed, anoutlet valve 34 associated with thepump cylinder 28 will open to allow the compressed air to exit thecavity 30. Once compressed, the air has a “high pressure flow.” - A detachable high-
pressure hose 36, inserted through anopening 37 in the inflator housing, is attached to theoutlet valve 34. For convenience, acavity 40 in theinflator housing 4 is provided to store the high-pressure hose 36 when it is not in use. Thehose 36 has a diameter such that the air that exits thepump cylinder 28 maintains a high pressure flow. Optionally, a chuck orvalve 38 is fluidly connected to the high-pressure hose at anend 42 opposite theoutlet valve 34. Thechuck 38 allows the high-pressure hose 36 to be attached a valve stem for the inflation of items requiring high pressure flow, such as vehicle or bicycle tires. - A
fan 44 is attached to asecond end 46 of themotor assembly 12 and is driven by themotor 14. As explained further below, the fan provides both a high volume/low pressure flow of air (“high flow air”) and cooling air. In one preferred embodiment, the fan will have an outer diameter of 73 millimeters, a capacity of nine cubic feet per minute, and will be made of a glass-filled nylon material. In other embodiments, fans having a different size and capacity, as well as being made of a different material, may be used. Examples of other suitable materials include aluminum and poly carbonate. Moreover, although a preferred embodiment contemplates one fan, depending on the volume/pressure requirements for the air flow, more than one fan may be used in axial alignment at thesecond end 46 of themotor assembly 12. - The
fan 44 is located within a blower housing 48 (FIG. 4 ). Together, thefan 44 andblower housing 48 have a volute-shaped area that forms a centrifugal or axial blower that both provides high flow air for the inflation of high-volume items and cooling air to cool the components within theinflator housing 4. Air enters into theblower housing 48 andfan 44 through anopening 50 in theblower housing 48. - The
blower housing 48 includes aguide 52 that provides a passage for, and prevents the dispersal of, high flow of air from the fan. Preferably, the high flow air will be projected in a direction tangential to thefan 44. Advantageously, theguide 52 also acts as a passage for the egress of heat generated by thepump cylinder 28 and themotor assembly 12, which exits with the high flow air generated by thefan 44. - Optionally, an
end 58 of a detachable high-flow hose 60 may be attached to theguide 52. Generally, the high-flow hose 60 will have a diameter larger than the high-pressure hose and is suitable for inflating items that have larger volumes, such as air mattresses. Anadapter 62 may be attached to the high-flow hose at anend 64 opposite theend 58 attached to theguide 52. Theadapter 62 provides for the attachment of the high-flow hose to a valve (not shown) normally associated with an item for inflation. As with the high-pressure hose, the high-flow hose 60 may be stored in asecond cavity 40 in the inflator housing. - The operation of the DC inflator will now be described: Upon actuation of the
trigger 13, themotor assembly 14 is energized. Themotor assembly 14, in turn, drives thefan 44 that is located within theblower housing 48. Thefan 44 generates a centrifugal force. The centrifugal force draws air entering theair intake 9 across thepump cylinder 28,piston 26,crankshaft 24, andmotor assembly 14. The air cools the afore-mentioned components. The circulation of the cooling air is shown inFIG. 2 and is depicted witharrows 54. - At the same time it creates a source of cooling air, the
fan 44 also creates high flow air for inflating larger-volume items. Thefan 44 draws in the air entering through theopening 50 of theblower housing 48 and generates high flow air that passes into theguide 52. The high flow air and any heat generated by the fan then exit theinflator housing 4 through anexhaust opening 56 in the housing. Notably, the air exiting the exhaust opening may be used to “blow” accumulated debris. If the high-flow hose 60 is inserted through theexhaust opening 56 and attached to theguide 52, thehose 60 may be used to inflate high-volume items with the high flow air. - The high pressure flow is generated at the same time as the cooling air and high flow air. Upon its actuation, the
motor assembly 14 also drives thecrankshaft 24 and attachedpiston 26. As the piston moves downwardly, it creates a vacuum that draws air into thecavity 30 of thepump cylinder 28. As thepiston 26 moves upwardly, it compresses the air, causing the air to become highly pressurized. Theoutlet valve 34 then opens to allow the high pressure air to exit thecavity 30 and pass into thehigh pressure hose 36. The diameter of thehigh pressure hose 36 maintains the pressure of the air high in order to inflate items requiring high pressure air. - Thus, a novel inflator has been described herein. The advantages associated with the inflator are numerous. First, only one motor is required to provide both high pressure flow and high flow air, thus reducing number of components associated with the inflator and, by extension, the size and weight of the inflator.
- Second, the fan is advantageously utilized to simultaneously cool the inflator components and provide high flow air. As described above with respect to
FIG. 5 , many prior art inflators solely provide high pressure/low volume air that is unsuitable for the inflation of larger-volume items inflation as inflation will take a large amount of time (i.e., 40 minutes or more). In contrast, due to the high flow air generated by the inflator described herein, larger-volume items can be inflated quickly. Furthermore, the novel inflator provides a guiding structure to ensure that the high flow air, as well as any heat generated by the fan, does not disperse inside the inflator housing, causing the inflator to become hot to the touch or to overheat. - It is therefore intended that the foregoing detailed description be regarded as illustrative rather than limiting. For example, although in a preferred embodiment the
inflator 2 uses a battery power source, those skilled in the art will readily recognize that the inflator could utilize a cord that can be plugged into a car lighter or an AC outlet as possible power sources. Therefore, it is to be understood that it is the following claims, including all equivalents, that are intended to define the spirit and scope of this invention.
