[0029] This application provides an air compressor, see [link to relevant documentation] Figures 1 to 3 As shown, the air compressor in this embodiment includes a casing 100 and an air compressor unit 200. In the following text, it will first be described in conjunction with... Figures 1 to 7 The structure of chassis 100 will be introduced. Then, in conjunction with... Figure 8 The structure of the air compressor unit 200 is described below.

[0030] The chassis 100 includes a base 110, a first chassis shell 120, and a second chassis shell 130, with the air compressor unit 200 mounted on the base 110. The base 110 includes a first end 111 and a second end 112 opposite to each other. In some examples, the base 110 may include a base plate and two support portions disposed at the bottom of the base plate, with the two support portions respectively disposed at both ends of the base plate to stably support the base plate. Of course, the base 110 described above is merely exemplary. In some examples, the base 110 serves as a support structure for the air compressor unit 200, and any suitable structure capable of stably supporting the air compressor unit 200 can be selected.

[0031] A first chassis 120 is rotatably connected to a first end 111 of a base 110, and a second chassis 130 is rotatably connected to a second end 112 of the base 110. The first chassis 120 and the second chassis 130 can have a first state and a second state. The first state can be understood as a snap-fit ​​state. For example... Figure 1 and Figure 2 As shown, when the first housing 120 and the second housing 130 are in the first state, the first housing 120 and the second housing 130 are interlocked above the base 110 and cover the air compressor unit 200. The second state can be understood as an open state. Figure 3 As shown, when the first housing 120 and the second housing 130 are in the second state, the first housing 120 and the second housing 130 are rotated away from the base 110, and the air compressor unit 200 can be fully exposed above the base 110.

[0032] When it is necessary to open the first housing 120 and the second housing 130, such as when the air compressor unit 200 needs to be inspected and maintained, the first housing 120 and the second housing 130 can be rotated in opposite directions, thereby switching the first housing 120 and the second housing 130 from a first state to a second state. For example, the first housing 120 can be rotated counterclockwise and the second housing 130 can be rotated clockwise, thereby switching the first housing 120 and the second housing 130 from a first state to a second state. Figure 1 The first state shown is switched to the state shown below. Figure 3 The second state is shown.

[0033] When it is necessary to close the first housing 120 and the second housing 130, for example after completing the inspection and maintenance of the air compressor unit 200, the first housing 120 and the second housing 130 can be rotated towards each other, thereby switching the first housing 120 and the second housing 130 from a second state to a first state. For example, the first housing 120 can be rotated clockwise and the second housing 130 can be rotated counterclockwise, thereby switching the first housing 120 and the second housing 130 from a second state to a first state. Figure 3 The second state shown switches to the state shown below. Figure 1 The first state is shown.

[0034] In this embodiment of the air compressor, a first housing 120 and a second housing 130 are rotatably connected to both ends of a base 110. When maintenance of the air compressor unit 200 is required, the first housing 120 and the second housing 130 can be opened by rotating them in opposite directions to fully expose the air compressor unit 200. After maintenance of the air compressor unit 200 is completed, the first housing 120 and the second housing 130 can be closed over the base 110 by rotating them in opposite directions, thereby covering the air compressor unit 200. This eliminates the need to disassemble and reassemble each door panel and / or top panel of the housing 100 individually, significantly reducing maintenance difficulty and improving maintenance efficiency.

[0035] In some embodiments, such as Figure 1 and Figure 2 As shown, the first housing 120 includes an upper housing plate 121, a first side housing plate 122, a second side housing plate 123, and a third side housing plate 124. The top end of the first side housing plate 122 is connected to one side edge of the upper housing plate 121, and the bottom end of the first side housing plate 122 is rotatably connected to the first end 111. The second side housing plate 123 and the third side housing plate 124 are disposed on opposite sides of the upper housing plate 121 along a first direction, and one side edge of the second side housing plate 123 and one side edge of the third side housing plate 124 are respectively connected to the opposite side edges of the first side housing plate 122. In this way, the bottom of the first housing 120 and the end near the second end 112 are open, and the first housing 120 is less likely to interfere with the air compressor unit 200 during rotation. It is understood that the specific structure of the first housing 120 described above is only exemplary. In practical applications, the first housing 120 can be constructed into other shapes or other structures according to actual needs.

[0036] In some embodiments, the first housing 120 can be rotatably connected to the base 110 via at least one first hinge 160. As an example, such as Figure 2 As shown, the first side shell plate 122 can be connected to the first end 111 of the base 110 via two first hinges 160. This results in a simple structure, higher cost, and stable and reliable operation.

[0037] In some embodiments, the first chassis 120 may be provided with a handle 125 to facilitate opening and closing of the first chassis 120. As an example, such as... Figure 1 and Figure 2 As shown, the upper shell plate 121 may have a recessed groove on the inner side of the upper shell plate 121 near the second housing shell 130, through which a handle 125 can be formed. In this way, a concealed handle 125 can be formed, which helps to keep the appearance surface of the air compressor flat and facilitates the storage and transportation of the air compressor.

[0038] In some embodiments, such as Figure 1 , Figure 3 and Figure 4As shown, the second housing 130 includes a frame 131 and a baffle 136. The bottom end of the frame 131 is rotatably connected to the second end 112, and an opening 135 is provided on the frame 131. The baffle 136 is detachably connected to the opening 135. The opening 135 on the frame 131 provides another way to open part of the housing 100 for inspection and maintenance. When it is not necessary to expose the entire air compressor unit 200, the baffle 136 can be removed from the frame 131 to open the opening 135, thereby exposing a partial structure of the air compressor unit 200. In this way, maintenance personnel can perform partial maintenance on the air compressor unit 200 through the opening 135, which can further improve the flexibility and convenience of air compressor inspection and maintenance.

[0039] As an example, the frame 131 may include an upper frame 132, a first side frame 133, and a second side frame 134. The upper frame 132 may extend laterally, and the first side frame 133 and the second side frame 134 may extend vertically. The top end of the first side frame 133 may be connected to one end of the upper frame 132, and the top end of the second side frame 134 may be connected to the other end of the upper frame 132. The bottom ends of the first side frame 133 and the second side frame 134 may be rotatably connected to the base 110. Thus, an inverted U-shaped frame 131 can be formed, with an opening 135 formed in the lower middle part of the frame 131.

[0040] In some embodiments, the second housing 130 can be rotatably connected to the base 110 via at least one second hinge 170. As an example, the bottom end of the first side frame 133 can be connected to the second end 112 via one second hinge 170, and the bottom end of the second side frame 134 can be connected to the second end 112 via another second hinge 170. Thus, the second housing 130 can be stably hinged at the second end 112.

[0041] In some embodiments, the baffle 136 is detachably connected to the opening 135. For example, the baffle 136 can be snapped into the opening 135. In some examples, such as Figure 1 and Figure 4 As shown, the baffle 136 is provided with a first locking structure 140, which can lock the baffle 136 and the frame 131, thereby securing the baffle 136 at the opening 135. Thus, when the baffle 136 needs to be removed, the first locking structure 140 can be switched to the unlocked state, allowing the baffle 136 to be easily removed. After maintenance, the baffle 136 can be reinstalled at the opening 135, and the first locking structure 140 can be switched to the locked state to lock the baffle 136 and the frame 131.

[0042] In some examples, combined Figure 4 , Figure 5 and Figure 6 As shown, the first locking structure 140 may include a rotatable locking pin 141, which is configured to rotate to the inside of the frame 131 to prevent the baffle 136 from disengaging from the access port by flipping outward of the frame 131.

[0043] As an example, the first locking structure 140 may include a lock body 143, a lock cylinder 142, and a locking pin 141. The lock body 143 may be connected to the top near the baffle 136, and a through hole may be provided in the middle of the lock body 143. The lock cylinder 142 is rotatably connected to the through hole, and one end of the lock cylinder 142 may be exposed on the outside of the baffle 136. The other end of the lock cylinder 142 may extend from the through hole and connect with the locking pin 141. In this way, the lock cylinder 142 can be driven to rotate the locking pin 141 by an auxiliary tool such as a key.

[0044] For example, such as Figure 6 As shown, the free end of the locking pin 141 can be rotated to the inside of the upper frame 132 to lock the baffle 136 and the frame 131. When it is necessary to remove the baffle 136, the locking pin 141 can be rotated to a position that avoids the upper frame 132, and the baffle 136 can be removed from the frame 131 by flipping it outward.

[0045] It should be understood that the above-mentioned first locking structure 140 and the installation position of the first locking structure 140 are only exemplary. Other locking structures that can lock the baffle 136 and the frame 131 can be selected according to actual needs. The first locking structure 140 can also be installed, for example, near the bottom end of the baffle 136, near one side edge of the baffle 136, etc.

[0046] In some embodiments, such as Figures 3 to 5 ,as well as Figure 7 As shown, the second end 112 may be provided with at least one pin hole 113. The bottom end of the baffle 136 is provided with at least one pin 150 corresponding to the at least one pin hole 113. The pin 150 may be configured to be inserted into the corresponding pin hole 113 to lock the baffle 136 and the base 110. In this way, another structure for the baffle 136 to engage with the frame 131 is provided.

[0047] As an example, such as Figure 3 , Figure 5 and Figure 7 As shown, the second end 112 of the base 110 may be provided with two pin holes 113. Correspondingly, the bottom end of the baffle 136 may be provided with two pins 150, and the positions of the two pins 150 correspond to the positions of the two pin holes 113 respectively.

[0048] It should be noted that in practical applications, a first locking structure 140 can be provided at the top of the baffle 136, and a pin 150 can be provided at the bottom of the baffle 136. In this way, the baffle 136 can be stably fixed at the opening 135. It should also be noted that the baffle 136 can also be connected to the frame 131 by other connection methods such as hinges, and is not limited to snap-fit.

[0049] Therefore, the chassis in this embodiment provides multiple opening methods, allowing for the selection of an appropriate method to open the chassis according to maintenance needs. Specifically, in one case, the first chassis shell 120 and the second chassis shell 130 can be fully opened to fully expose the air compressor unit 200. In another case, either the first chassis shell 120 or the second chassis shell 130 can be opened separately to expose a portion of the air compressor unit 200. In yet another case, the baffle 136 can be opened to expose a portion of the air compressor unit 200's structure (e.g., the electrical control box 219, the secondary oil-gas separator 216, etc.). This significantly improves the convenience and flexibility of inspection and maintenance.

[0050] In some embodiments, such as Figure 1 and Figure 3 As shown, the air compressor unit 200 has an exhaust pipe 220 connected to its outlet end. The edges of the first housing 120 and / or the second housing 130 are provided with notches, through which the exhaust pipe 220 extends to the outside of the housing 100. These notches can be configured to allow the exhaust pipe 220 to move in or out during rotation of the first housing 120 and / or the second housing 130. Specifically, during the transition from a first state to a second state, the exhaust pipe 220 can be moved out of the notch. During the transition from a second state to a first state, the exhaust pipe 220 can be moved into the notch. This allows the exhaust pipe 220 to be maintained without removal during maintenance, further improving ease of maintenance.

[0051] As an example, such as Figure 1 and Figure 3 As shown, a U-shaped notch is provided on the edge of the second side frame 134 near the first chassis shell 120, and the position of this notch corresponds to the position of the exhaust pipe 220. Thus, when the second chassis shell 130 is opened, the exhaust pipe 220 can be smoothly moved out through the notch. When the second chassis shell 130 is closed, the exhaust pipe 220 can be smoothly moved into the notch.

[0052] It is understood that in practical applications, the notch is not limited to being provided on the edge of the second chassis housing 130. A notch can also be provided on the edge of the first chassis housing 120, or both the edges of the first chassis housing 120 and the second chassis housing 130 can be provided simultaneously. If notches are provided on both the edges of the first chassis housing 120 and the second chassis housing 130, the two notches can be positioned opposite each other. Furthermore, the notch is not limited to being provided on the side edge of the first chassis housing 120, but can also be provided, for example, on the upper edge of the first chassis housing 120.

[0053] In some embodiments, such as Figure 1 and Figure 2 As shown, the air compressor may further include at least one second locking structure 180. This at least one second locking structure 180 can lock the first housing 120 and the second housing 130. Thus, during operation, the second locking structure 180 can lock the first housing 120 and the second housing 130, preventing uncontrolled opening of the first housing 120 and the second housing 130. When maintenance is required, the second locking structure 180 can be switched to the unlocked state, allowing for convenient and quick opening of the first housing 120 and the second housing 130.

[0054] As an example, the second locking structure 180 may include, for example, a latch lock. Of course, the second locking structure 180 is not limited to a latch lock; it may employ any other suitable locking structure capable of locking the first housing 120 and the second housing 130. This application does not limit the specific type of the second locking structure 180.

[0055] The following will combine Figure 8 The structure of the air compressor unit 200 is provided as an example. However, it should not be construed that the air compressor unit 200 is limited to the structure shown below. Any suitable air compressor unit 200 can be selected according to actual needs, and the embodiments of this application do not specifically limit it in this regard.

[0056] In some embodiments, such as Figure 8 As shown, the air compressor unit 200 may include an air compressor head 211, a drive motor 212, an air filter 214, a primary oil-gas separator 215, a secondary oil-gas separator 216, an oil cooler 218, an oil filter 217, and an electrical control box 219.

[0057] The drive motor 212 can be connected to the air compressor head 211 for transmission, and the drive motor 212 can drive the air compressor head 211 to operate. The air filter 214 can be connected to the air intake end of the air compressor head 211 through the air intake valve 213. In this way, the air filter 214 can filter out impurities in the air to improve the air cleanliness.

[0058] The outlet of the air compressor head 211 can be connected to the primary oil-gas separator 215. The air compressor head 211 can discharge the mixture of compressed air and lubricating oil (i.e., the oil-gas mixture) into the primary oil-gas separator 215. The primary oil-gas separator 215 can separate the lubricating oil and compressed air.

[0059] The inlet of the secondary oil-gas separator 216 can be connected to the outlet of the primary oil-gas separator 215. The compressed gas discharged from the primary oil-gas separator 215 can enter the secondary oil-gas separator 216, where it undergoes secondary oil-gas separation to improve the cleanliness of the compressed gas. The outlet of the secondary oil-gas separator 216 can be connected to the exhaust pipe 220, allowing the compressed gas that has undergone secondary oil-gas separation to be discharged outside the air compressor, for example, to be supplied to the air-consuming process.

[0060] The oil outlets of the primary oil-gas separator 215 and / or the secondary oil-gas separator 216 can be connected to the oil cooler 218, which cools the lubricating oil. The oil outlet of the oil cooler 218 can be connected to the oil filter 217, which removes impurities from the lubricating oil. The oil outlet of the oil filter 217 can be connected to the oil inlet of the air compressor head 211 to supply low-temperature, clean lubricating oil to the air compressor head 211. The electrical control box 219 can contain power supply equipment to supply power to the air compressor unit 200.

[0061] In some embodiments, the top of the base 110 may be provided with a first region and a second region, the second region being located on one side of the first region in a first direction, and both the first region and the second region extending along a second direction perpendicular to the first direction.

[0062] A primary oil-gas separator 215 is located in the first area. The drive motor 212, air compressor head 211, and secondary oil-gas separator 216 are positioned above the primary oil-gas separator 215. An air filter 214 is connected above the air compressor head 211. An oil filter 217, oil cooler 218, and electrical control box 219 are located in the second area and arranged sequentially along a second direction. This arrangement of the air compressor unit 200 is neat and compact, which helps to reduce the overall volume of the air compressor unit 200 and, consequently, the overall size of the air compressor.

[0063] There may or may not be a clear connection between the first and second areas. If there is no clear connection between the first and second areas, the area occupied by the primary oil-gas separator 215 can be considered the first area. The area occupied by the oil filter 217, oil cooler 218, and electrical control box 219 can be considered the second area.

[0064] As an example, such as Figure 8 As shown, the upper surface of the base 110 can be rectangular. One long side of this rectangle can extend parallel to the X-axis, and one short side can extend parallel to the Y-axis. The first direction can be the Y-axis, and the second direction can be the X-axis. The primary oil-gas separator 215 can be deployed near one edge of the base 110, and the primary oil-gas separator 215 can extend along the X-axis. The oil filter 217, oil cooler 218, and electrical control box 219 can be deployed near the other edge of the base 110, and the oil filter 217, oil cooler 218, and electrical control box 219 can be arranged sequentially along the X-axis. In this case, the rectangular area corresponding to the primary oil-gas separator 215 can be defined as the first area, and the rectangular areas corresponding to the oil filter 217, oil cooler 218, and electrical control box 219 can be defined as the second area.

[0065] As an example, such as Figure 1 , Figure 2 and Figure 3 As shown, the first region is adjacent to the second side shell plate 123, and the second region is adjacent to the third side shell plate 124.

[0066] In some embodiments, the base 110 has at least one air inlet at its bottom, extending to the top, for example, communicating with the first and / or second regions. As an example, such as... Figure 3 As shown, the base 110 may be provided with a first air inlet 114 extending into the first region and / or the second region, through which heat-generating elements such as the primary oil-gas separator 215 can be directly cooled. Optionally, the first air inlet 114 may be provided with a mesh structure or a grille structure, and its exterior is provided with a pre-filter structure to prevent external debris from entering the chassis.

[0067] In some embodiments, the second side shell 123 is provided with at least one air inlet. As an example, the second side shell 123 may be provided with a second air inlet 126, which may be connected to the drive motor 212 for direct heat dissipation. As another example, the second side shell 123 may be provided with a third air inlet 127, which may be connected to the air filter 214 to provide separate air intake for the machine head, thereby improving the safety and efficiency of machine head operation.

[0068] In some embodiments, the third side shell 124 is provided with at least one exhaust port to extract hot air from the chassis 100 by at least one fan. As an example, the third side shell 124 may be provided with an exhaust port 128, the oil cooler 218 may be provided with at least one fan, and / or the electrical control box 219 may be provided with at least one fan. The fans can guide the hot air from the oil cooler 218 and / or the electrical control box 219 to the exhaust port 128, and then discharge it outside the chassis 100 via the exhaust port 128.

[0069] Therefore, by arranging the air compressor unit 200 and setting the corresponding air inlet and outlet, the spatial layout of the air compressor 100 can be optimized and the heat dissipation efficiency can be improved.
