Description

Technical Field

[0001] This application relates to the field of air compressor technology, and in particular to an air storage structure for a portable air compressor. Background Technology

[0002] Portable air compressors are a common power tool widely used in various scenarios such as vehicle tire inflation, ball inflation, and emergency inflation of outdoor equipment.

[0003] Portable air compressors, due to their portability requirements, often use external air tanks, or, as proposed in CN223190577U, a portable handheld air compressor that mounts the entire air tank onto the machine body. However, this mounting method often results in an uncompacted overall structure layout to accommodate the air tank, requiring dedicated installation space and making the machine more bulky. Therefore, the purpose of this application is to solve the above problems.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, this application provides an air storage structure for a portable air compressor to solve one of the aforementioned technical problems.

[0006] The technical solution adopted by this application to solve its technical problem is an air storage structure for a portable air compressor, including: a body on which a piston cylinder is provided for compressing air; and a support tube disposed on the body and connected to the piston cylinder, wherein the tube body itself constitutes a sealed pressure vessel and its internal cavity forms an air storage chamber for storing compressed air.

[0007] In some embodiments, a communicating vessel is provided on the body or support tube for connecting the support tube and the body.

[0008] In some embodiments, the communicating vessel is provided with a pressure gauge and a pressure relief valve.

[0009] In some embodiments, the communicating vessel has two communicating holes and one vent hole, one communicating hole being directly connected to the support tube or piston cylinder, the other communicating hole being connected to the support tube or piston cylinder through a connecting tube, and the vent hole being used to connect to an external inflation device.

[0010] In some embodiments, the support tube is a frame structure surrounding the body, which itself constitutes part of the skeleton supporting the body.

[0011] In some embodiments, the bottom of the machine body is provided with support legs for supporting the machine body, and the support tube can support the placement of the machine body together with the support legs.

[0012] In some embodiments, a support plate is horizontally arranged on the support tube, and the support plate is fixedly connected to the support leg.

[0013] The beneficial effects of this application are as follows: by using the support tube as the gas storage chamber, the internal structure of the machine body does not need to consider the storage location of the gas tank, eliminating the installation space of the gas tank, and making the internal structure of the machine body more compact. At the same time, the layout of the support tube around the machine body forms a protective frame and is conducive to heat dissipation. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0020] In the embodiments of this application, please refer to Figure 1-3As shown, this application provides an air storage structure for a portable air compressor, mainly including: a body 1, on which a piston cylinder 11 is provided for compressing air; a support pipe 2, which is disposed on the body 1 and communicates with the piston cylinder 11, the pipe body of the support pipe 2 itself constitutes a sealed pressure vessel, and its internal cavity forms an air storage chamber for storing compressed air.

[0021] Specifically, the motor drives the piston cylinder 11 to compress air, and the compressed air enters the air storage chamber of the support tube 2 for storage. The support tube 2, which serves as the air storage chamber, can provide support or be carried by hand without affecting the internal parts layout of the machine body 1, making the internal structure of the machine body 1 more compact.

[0022] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0023] Preferably, the body 1 or the support tube 2 is provided with a connector 3 for connecting the support tube 2 and the body 1. The connector 3 has a three-way structure and is connected to the support tube 2, the body 1, and an external inflation device. The connector 3 has two connecting holes 31 and one air outlet 32. One connecting hole 31 is directly connected to the support tube 2 or the piston cylinder 11, and the other connecting hole 31 is connected to the support tube 2 or the piston cylinder 11 through a connecting pipe 35. The air outlet 32 ​​is used to connect to the external inflation device.

[0024] Reference Figure 1 As shown in Figure 3, the communicating vessel 3 is equipped with a pressure gauge 33 and a pressure relief valve 34. The pressure gauge 33 is used to observe the compressed air pressure inside the support tube 2, and the pressure relief valve 34 is used to automatically open and release pressure when the air pressure inside the support tube 2 abnormally exceeds the safe value, so as to avoid damage to the support tube 2 due to overpressure.

[0025] Preferably, the support tube 2 is a frame structure surrounding the body 1, which itself constitutes part of the skeleton supporting the body 1. This arrangement allows the support tube 2 to provide a certain degree of protection for the body 1.
