[0035] See also Figure 1As shown, the embodiment of the utility model relates to an air compressor 100, the air compressor 100 includes a gas tank 1, a capacitor box 5 installed on the outer surface of the gas tank 1, a cylinder assembly 2 and a control assembly 6 arranged above the gas tank 1, a wind cover assembly 3 connected to the cylinder assembly 2, a motor assembly (not shown) and a drive assembly (not shown) contained in the cylinder assembly 2, a silencer 4 connected to the cylinder assembly 2, a foot pad 7 and a roller 8 installed at the bottom of the gas tank 1, and a handle assembly 9 fixed to the left side of the gas tank 1 and close to the edge, the wind cover assembly 3 can prevent large particles of impurities in the environment from being sucked into the cylinder assembly 2 to damage the cooling fan, and at the same time, can effectively guide the cooling wind to the motor assembly, and the cooling effect is good. The capacitor box 5 is electrically connected to the control assembly 6, the control assembly 6 controls the motor assembly, and the motor assembly drives the drive assembly to reciprocate in the cylinder assembly 2 to compress the external gas and store it in the gas tank 1.

[0036] In this embodiment, the silencer 4 is installed between the cylinder assemblies 2 to prevent the silencer 4 from being damaged by collision during operation, and effectively improve the noise generated by the air compressor 100 during operation.

[0037] Specifically, the gas tank 1 is roughly cylindrical in shape, the cylinder assembly 2 and the control assembly 6 are located at the two ends of the upper side of the gas tank 1, the foot pad 7 and the roller 8 are also distributed at the two ends of the lower side of the gas tank 1, and the foot pad 7 and the handle assembly 9 are both located on the left side of the gas tank 1. The foot pad 7 is preferably made of rubber. When the air compressor 100 is working, the rubber foot pad 7 can absorb the vibration of the air compressor 100 when it is working, reduce the noise during work, and is not easy to damage the floor when it is in direct contact with the floor; in addition, when the air compressor 100 is stationary on the ground, the foot pad 7 can limit the movement of the roller 8. The setting of the roller 8 is used for changing the work place without moving the heavy air compressor 100. The user only needs to pull the handle assembly 9 upwards to make the foot pad 7 off the ground, and the air compressor 100 can be moved in the front and rear directions via the roller 8. The operation is simple and convenient for the user.

[0038] See also Figures 2 to 4As shown, the handle assembly 9 includes a frame handle 91 fixed to the gas tank 1 and an extended handle 92 slidably connected to the frame handle 91, and the frame handle 91 includes a fixed rod 911 connected to the gas tank 1, a mounting rod 912 connected to the fixed rod 911 at an angle, and a pull rod 913 located at the top of the frame handle 91. The fixed rod 911 can be fixed to the gas tank 1 by welding, and the present application does not limit the connection method of the fixed rod 911, as long as the fixed rod 911 can be reliably fixed to the gas tank 1.

[0039] In this embodiment, the extended handle 92 includes a sliding portion 921, a limiting portion 922 disposed above the sliding portion 921, a rod portion 924 connecting the sliding portion 921 and the limiting portion 922, and a handle portion 923 located at the top of the rod portion 924, and the sliding portion 921 slides on the mounting rod 912. The extended handle 92 has two states of stretching and contraction on the frame handle 91, which is convenient for the user to adjust the different states of the handle assembly 9 according to different situations. When the air compressor 100 needs to be moved, the extended handle 92 is extended. At this time, the height of the handle assembly 9 is ergonomic, and moving or pushing the air compressor 100 is labor-saving and convenient, which improves the user's sense of use; when the air compressor 100 is stored, the extended handle 92 is contracted, which is conducive to reducing the overall volume of the air compressor 100 and facilitating packaging and storage.

[0040] Preferably, the extended handle 92 is made of plastic, which is lighter than a general iron extended handle, effectively reducing the weight of the air compressor 100 and reducing production costs.

[0041] Please combine Figure 2 and Figure 3 As shown, the sliding portion 921 is detachably mounted on the frame handle 91 , which facilitates the user to disassemble or assemble the extended handle 92 , thereby further improving the portability of the air compressor 100 .

[0042] More specifically, the sliding portion 921 includes a through sliding groove 9211 and a mounting notch 9212 opened on the side of the sliding groove 9211, the sliding groove 9211 cooperates with the mounting rod 912, the inner wall diameter of the sliding groove 9211 is larger than the diameter of the mounting rod 912, and the opening spacing of the mounting notch 9212 is smaller than the diameter of the mounting rod 912, which can ensure that the extended handle 92 is movable on the frame handle 91 and prevent the extended handle 92 from falling off, thereby preventing the user from having a safety accident while carrying the air compressor 100.

[0043] See also Figure 2As shown, the limiting part 922 is provided with a supporting groove 9221. When the extended handle 92 is in the stretched state, the supporting groove 9221 abuts against the mounting rod 912 and the pull rod 913 at the same time; when the extended handle 92 is in the retracted state, the supporting groove 9221 abuts against the mounting rod 912 only. The mounting rod 912 and the pull rod 913 have an arc transition. The bottom of the supporting groove 9221 is arranged in an arc surface, which can be matched with the arc transition of the frame handle 91. Two clamping plates 9222 extend upward from both sides of the supporting groove 9221. The distance between the two clamping plates 9222 is smaller than the diameter of the pull rod 913, so that when the user pulls the extended handle 92 to the uppermost end, the clamping plates 9222 clamp the frame handle 91 and will not fall down, thereby satisfying the user's need to lengthen and fix the extended handle 92 at any time, and improving the transportation safety at the same time.

[0044] More specifically, the handle portion 923 is provided with an arc-shaped slot 9231, and the arc-shaped slot 9231 is provided above the pull rod 913. When the extended handle 92 is in the retracted state, the arc-shaped slot 9231 abuts against the pull rod 913. When the user needs to put away the extended handle 92, he only needs to lightly press the handle portion 923, and the extended handle 92 slides downward along the fixed rod 911 until the arc-shaped slot 9231 abuts against the pull rod 913, preventing the extended handle 92 from longitudinally separating from the frame handle 91, thereby meeting the user's storage needs.

[0045] See also Figure 3 As shown, in the projection of the moving direction of the air compressor 100, the shape of the rod portion 924 is consistent with the shapes of the mounting rod 912 and the pull rod 913. When the extended handle 92 is in the retracted state, the volume of the air compressor 100 is further reduced, thereby improving the portability of the air compressor 100.

[0046] In this embodiment, the sliding portion 921 , the limiting portion 922 , the handle portion 923 , and the rod portion 924 are integrally formed.

[0047] The utility model installs an extended handle 92 on the basis of the original frame handle 91, and the extended handle 92 is retractable on the frame handle 91, which is convenient for the user to adjust the different states of the handle assembly 9, which can not only improve the user's feeling of use, but also facilitate the packaging and storage of the air compressor 100; the extended handle 92 is provided with a sliding portion 921, and the sliding portion 921 is detachably installed on the frame handle 91, which is convenient for the user to disassemble or assemble the extended handle 92, and further improve the portability of the air compressor 100; in addition, a limiting portion 922 is provided above the sliding portion 921. After the user extends the extended handle 92, the limiting portion 922 engages with the frame handle 91, which is convenient for fixing the extended handle 92 to the frame handle 91, preventing the extended handle 92 from sliding down and detaching during the pulling of the air compressor 100, thereby improving transportation safety.
