The present invention relates to a compressor, and more particularly to a compressor having a heat dissipation path arranged on the pneumatic cylinder thereof.
Currently, there are two major types of compressor, which are the general type and the high-speed type. General type has lower operation speed and mainly relies on a plurality of heat dissipation fins arranged on the pneumatic cylinder as its heat dissipation mechanism for cooling and allowing the compressor to continuously operate. Relative technologies include the prior arts disclosed in Taiwan Pat. Nos. 094202857, 095200952, 095218837, and etc.. In order to further enhance the heat dissipation function of the compressor, some technologies include adding internal cooling fan to cool the driving motor, but keeping use the pneumatic cylinder heat dissipation fin mechanism on the pneumatic cylinder. These prior arts include technologies disclosed by Taiwan Pat. Nos. 80207381, 090203389, 096203128, 105217577, and etc.. Unfortunately, these conventional practices can only provide limited heat dissipation ability to the pneumatic cylinder, which may render overheat and decrease of performance of the operating pneumatic cylinder. Accordingly, some practitioners decided to add a cooling device outside the pneumatic cylinder of the pneumatic cylinder. For example, technology disclosed in Taiwan Pat. No. 101102543 adds a set of cooling fan on the exterior of the pneumatic cylinder. Although such practice does help on the heat dissipation of the pneumatic cylinder, it greatly increases the manufacturing cost of the entire compressor, that is still not an ideal design. Hence, substantially, there has not been an ideal heat dissipation mechanism in the technical field of compressor.
Besides, some other heat dissipation technologies are listed here for reference, including the technologies disclosed by Taiwan Pat. Nos. 104105158, 104100602, and 104200322. Even though the heat dissipation mechanism of a motor could be somehow different from that of the pneumatic cylinder of a compressor.
An object of the present invention is to provide a compressor that has a better heat dissipation ability.
Accordingly, the present invention provides a compressor which comprises a compressing motor, at least a pneumatic cylinder for compressing gas, and at least a cooling fan. The pneumatic cylinder comprises a cylinder support arranged on top of the compressing motor, a valve panel arranged on top of the cylinder support, a cylinder cover provided on top of the valve panel, and a piston connecting rod body slidably connected with the cylinder support. The cylinder support has a compression space formed and provided in a middle portion thereof for accommodating the piston connecting rod body, and a plurality of heat dissipating channels provided around the compression space. The valve panel provides a plurality of gas channels corresponding to the heat dissipating channels. The cylinder cover provides a plurality of heat dissipating passages corresponding to the heat dissipating channels and the gas channels. The heat dissipating channels, the gas channels, and the heat dissipating passages are arranged in series to jointly form a heat dissipation path, such that when the piston connecting rod body is driven by the compressing motor to conduct a gas compressing operation in the cylinder support, the cooling fan will also be driven to operate to drive the external gas to flow through the heat dissipation path that is jointly formed by the heat dissipating channels of the cylinder support, the gas channels of the valve panel, and the heat dissipating passages of the cylinder cover and to flow out. As a result, heat produced during the operation of the pneumatic cylinder can be transferred out to achieve an effective heat dissipation effect. The arrangement of the heat dissipation path enables a better heat dissipation function without additional parts or substantial changing the design of the mechanism, which allows the manufacturing cost of the compressor remaining under control.
Still further objects and advantages will become apparent from a consideration of the ensuing description and drawings.
These and other objectives, features, and advantages of the present invention will become apparent from the following detailed description, the accompanying drawings, and the appended claims.
The following description is disclosed to enable any person skilled in the art to make and use the present invention. Preferred embodiments are provided in the following description only as examples and modifications will be apparent to those skilled in the art. The general principles defined in the following description would be applied to other embodiments, alternatives, modifications, equivalents, and applications without departing from the spirit and scope of the present invention.
Referring to
During the operation of the compressor 1, the motor shaft 31 rotated by the gas compressing motor 3 will drive the connecting rods 441 and the cooling fans 5 coupled on the two ends thereof to run. At this moment, the pistons 442 which are driven respectively by the connecting rods 441 to move reciprocately in the cylinder supports 41 respectively to compress gas. Meanwhile, the cooling fans 5 bring external gas such as air to flow into the crank houses 22 through the heat dissipating channels 412 of the cylinder supports 41, as illustrated in the arrow direction in
In addition, it is worth mentioning that, the design of the compressing motor 3 of the compressor 1 according to the present invention allows both forward and backward rotations. For instance, on one hand, when the gas compressing motor 3 rotates forward, it can drive the cooling fans 5, as mentioned above, to inhale the external air to flow out through the heat dissipation path 6 for heat dissipation, as illustrated in the arrow direction in
One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting.
It will thus be seen that the objects of the present invention have been fully and effectively accomplished. The embodiments have been shown and described for the purposes of illustrating the functional and structural principles of the present invention and is subject to change without departure from such principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
