[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.
[0044] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0045] Example 1:
[0046] Please see Figure 1 and Figure 2 A novel compressor structure includes a housing 100, a first compression pump 200, an electric motor 300, a second compression pump 400, and a filter bottle 500.
[0047] The housing 100 has a hollow structure, such as a hollow cylindrical structure, including an upper opening and a lower opening. An upper cover is sealed to the upper opening, and a lower cover is sealed to the lower opening. The housing 100 can accommodate the first compression pump 200, the motor 300, and the second compression pump 400. Of course, the housing 100 can also be a commercially available structural form. This embodiment does not limit the structural form.
[0048] The first compressor pump 200, the motor 300, and the second compressor pump 400 are arranged sequentially from top to bottom within the housing 100. For example, the outer side of the first compressor pump 200 is fixedly connected to the inner wall of the housing 100, and the outer side of the motor 300 is fixedly connected to the inner wall of the housing 100. Similarly, the outer side of the second compressor pump 400 is fixedly connected to the inner wall of the housing 100. Thus, the housing 100 serves to accommodate and fix the first compressor pump 200, the motor 300, and the second compressor pump 400. The filter bottle 500 is located on one side of the housing 100. A first connecting pipe 600 is provided between the first compressor pump 200 and the filter bottle 500, and a second connecting pipe 700 is provided between the second compressor pump 400 and the filter bottle 500. During the operation of the compressor, the first connecting pipe 600 establishes a connection between the first compressor pump 200 and the filter bottle 500, and the second connecting pipe 700 establishes a connection between the second compressor pump 400 and the filter bottle 500. The filter bottle 500 removes particulate matter and oil mist that may affect the performance of the compressor and related equipment, which helps to ensure smooth operation and reduce the need for maintenance and repair.
[0049] As is known, a traditional twin-cylinder compressor includes two cylinders, both positioned below the motor 300. This means the compressor's center of gravity is essentially at the bottom, leading to a top-heavy condition during high-speed operation, which fails to meet the demands of large displacement. Therefore, this embodiment provides a novel compressor structure, including a first compression pump 200 and a second compression pump 400, which possesses the performance of a twin-cylinder compressor. Structurally, the first compression pump 200 and the second compression pump 400 are positioned above and below the motor 300, respectively, replacing the traditional twin-cylinder compressor's bottom-heavy design. This allows the compressor to achieve dynamic balance during operation, resulting in smoother operation, support for high-speed operation, and effectively reduced noise and vibration. This allows for the use of a smaller compressor to meet the demands of large displacement. Furthermore, the presence of the first compression pump 200 above the motor 300 makes the overall compressor structure stronger than the traditional twin-cylinder compressor structure, resulting in better stability during high-speed operation. Additionally, it eliminates the need for a counterweight, effectively saving costs.
[0050] Example 2:
[0051] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the compressor of this utility model. Please refer to [link / reference]. Figures 3-6 .
[0052] See Figure 3 and Figure 4In this embodiment, the first compression pump 200 includes a first upper support 210, a first cylinder 220, a first lower support 230, and a first crankshaft 240. The first upper support 210 is located above the first cylinder 220, the first lower support 230 is located below the first cylinder 220, and the first crankshaft 240 passes through the first upper support 210, the first cylinder 220, and the first lower support 230. The lower end of the first crankshaft 240 is located inside the electric motor 300, thereby realizing the independent compressed air function of the first compression pump 200.
[0053] The first upper support 210 and the first lower support 230 support the first cylinder 220. The first crankshaft 240 supports the first upper support 210 and the second lower support 430 and drives their rotation. The first cylinder 220 has a first compression chamber 221. A first ring 260 is rotatably provided in the first compression chamber 221. The first crankshaft 240 includes an eccentric portion. When the first crankshaft 240 is inserted through the first upper support 210, the first cylinder 220 and the first lower support 230, the eccentric portion of the first crankshaft 240 corresponds to the position of the first ring 260. When the compressor is running, the eccentric portion of the first crankshaft 240 drives the first ring 260 to rotate, and at the same time drives the first upper support 210 and the first lower support 230 to rotate at high speed, so that the gaseous refrigerant is drawn into the first compression chamber 221 and continuously compressed to a certain pressure, and then the compressed refrigerant is discharged.
[0054] Furthermore, the first compression pump 200 also includes a first muffler 250; the first muffler 250 is located above the first upper support 210, and the upper end of the first crankshaft 240 is connected to the first muffler 250, which can play a role in noise reduction.
[0055] Based on the traditional structure of the first upper support 210, it is known that the first upper support 210 is usually provided with an exhaust port for exhaust, and a valve plate is movable to block the exhaust port. When the compressor is running, the valve plate is affected by the gas discharged from the exhaust port, which will produce a knocking sound. In order to reduce the noise problem caused by this knocking sound and the noise problem generated inside the housing 100 after the high pressure gas is discharged, a first silencer 250 is provided above the first upper support 210. The first silencer 250 plays a role in refracting and silencing the noise.
[0056] The first silencer 250 and the first upper support 210 can be locked together by bolts or other locking components to ensure the stability of the connection between the first silencer 250 and the first upper support 210 and the stability of the compressor operation.
[0057] See Figure 5 and Figure 6In some embodiments, the second compression pump 400 includes a second upper support 410, a second cylinder 420, a second lower support 430, and a second crankshaft 440; the second upper support 410 is located above the second cylinder 420, the second lower support 430 is located below the second cylinder 420, and the second crankshaft 440 passes through the second lower support 430, the second cylinder 420, and the second upper support 410, with the upper end of the second crankshaft 440 located inside the electric motor 300, thereby enabling the second compression pump 400 to independently compress air.
[0058] The second upper support 410 and the second lower support 430 support the second cylinder 420. The second crankshaft 440 supports the second upper support 410 and the second lower support 430 and drives their rotation. The second cylinder 420 has a second compression chamber 421. A second ring 460 is rotatably provided in the second compression chamber 421. The second crankshaft 440 includes an eccentric portion. When the second crankshaft 440 is inserted through the second upper support 410, the second cylinder 420 and the second lower support 430, the eccentric portion of the second crankshaft 440 corresponds to the position of the second ring 460. When the compressor is running, the eccentric portion of the second crankshaft 440 drives the second ring 460 to rotate, and at the same time drives the second upper support 410 and the second lower support 430 to rotate at high speed, so that the gaseous refrigerant is drawn into the second compression chamber 421 and continuously compressed to a certain pressure, and then the compressed refrigerant is discharged.
[0059] Furthermore, the second compression pump 400 also includes a second silencer 450; the second silencer 450 is located above the second upper support 410 and can play a role in noise reduction.
[0060] Based on the traditional structure of the second upper support 410, it is known that the second upper support 410 is usually provided with an exhaust port for exhaust, and a valve plate is movable to block the exhaust port. When the compressor is running, the valve plate is affected by the gas discharged from the exhaust port, which will produce a knocking sound. In order to reduce the noise problem caused by this knocking sound and the noise problem generated inside the housing 100 after the high pressure gas is discharged, a second silencer 450 is provided above the second upper support 410. The second silencer 450 plays a role in refracting and silencing the noise.
[0061] In some embodiments, the lower end of the first crankshaft 240 is connected to the upper end of the second crankshaft 440 to achieve synchronous operation and improve the overall stability of the compressor structure.
[0062] Furthermore, the lower end of the first crankshaft 240 is connected to the upper end of the second crankshaft 440 by a thread, which facilitates the connection operation of the first crankshaft 240 and the second crankshaft 440, and also ensures the connection stability of the first crankshaft 240 and the second crankshaft 440.
[0063] For example, an internal thread is formed at the lower end of the first crankshaft 240 and an external thread is formed at the upper end of the second crankshaft 440. The internal thread on the first crankshaft 240 is connected to the external thread on the second crankshaft 440, thus establishing the connection relationship between the first crankshaft 240 and the second crankshaft 440 and determining the connection stability and operational consistency between the first crankshaft 240 and the second crankshaft 440.
[0064] This embodiment provides a novel compressor structure that employs independent first compression pump 200 and second compression pump 400, which can meet the requirements of high pressure, large flow rate and high speed.
[0065] Example 3:
[0066] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the compressor of this utility model. Please refer to [link / reference]. Figures 7-9 .
[0067] See Figure 7 In this embodiment, the motor 300 includes a stator 310 and a rotor 320. The outer side of the stator 310 is fixed to the inner wall of the housing 100, and the rotor 320 is rotatably disposed on the inner side of the stator 310. When the rotor 320 rotates, it drives the first compression pump 200 and the second compression pump 400 to compress air.
[0068] See Figure 8 and Figure 9 In some embodiments, a connector 800 is provided between the housing 100 and the filter bottle 500. During the overall use of the compressor, in order to ensure the integrity and connection stability between the filter bottle 500 and the housing 100, the connector 800 is used to connect the housing 100 and the filter bottle 500, thereby establishing a stable connection between the housing 100 and the filter bottle 500, realizing the overall structure of the compressor, and improving the stability during operation.
[0069] Furthermore, the connector 800 has a U-shaped structure, including a first connecting arm 810, a second connecting arm 820, and a third connecting arm 830 connected in sequence. The second connecting arm 820 is connected to the housing 100, and the first connecting arm 810 and the third connecting arm 830 are connected to the filter bottle 500. The structure of the connector 800 can ensure the connection stability between the housing 100 and the filter bottle 500.
[0070] For example, the first connecting arm 810 and the third connecting arm 830 can be welded to the outer wall of the filter bottle 500, and the second connecting arm 820 can also be welded to the outer wall of the housing 100 to ensure the connection stability between the connector 800 and the filter bottle 500 and the housing 100. In addition, the first connecting arm 810 and the third connecting arm 830 can also extend to the connecting parts for connecting with other components to meet the installation or limiting requirements of the compressor in different scenarios.
[0071] This utility model provides a novel compressor structure. By setting separate first and second compression pumps, located above and below the motor respectively, the compressor can achieve dynamic balance during operation, resulting in smoother operation, support for high-speed operation, and effective reduction of noise and vibration. This allows a small compressor to meet the needs of large displacement. Furthermore, because there is a first compression pump above the motor, compared with the traditional twin-cylinder compressor structure, the overall compressor structure is stronger and more stable at high speeds. In addition, there is no need to add a balance block, effectively saving costs.
