[0021] In the description of the utility model, it is necessary to explain that the terms "upper", "lower", "left", "right", "inner", "outer" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, and the above description is simplified for the convenience of describing the utility model, and does not indicate or imply that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, therefore, it cannot be understood as the limitation of the utility model.

[0022] The singular form "one", "said" and "the" used in the specification contains plural form unless it is clear that the singular form "one", "said" and "the" contain plural form. The words "include", "contain" and "have" used in the specification indicate the existence of the claimed characteristics, but do not exclude the existence of one or more other characteristics.

[0023] In the specification, when it is said that an element is "on", "fixed to", "connected to", "joined to" or the like another element, it can be directly on, fixed to, connected to, joined to or in contact with the other element, or an intervening element can be present.

[0024] It is to be understood that the terms "first", "second", and so on can be used herein to describe various elements, but the elements should not be limited by these terms. The terms are only used to distinguish one element from another element. Therefore, a first element can be called a second element without departing from the teachings of the present application.

[0025] Exemplary embodiments of the present application will be described below with reference to the accompanying drawings. It is to be understood, however, that the present application can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. It is also to be understood that the embodiments disclosed herein can be combined in various ways, thereby providing more additional embodiments. In all the drawings, like reference numerals refer to the same or functionally similar elements.

[0026] Figure 1 The overall structure of the exhaust silencer of the compressor is shown, which includes an exhaust pipe 100 and exhaust end 102 and intake end 101 arranged at both ends of the exhaust pipe 100.

[0027] In combination with reference Figure 2 And Figure 3 The silencing mechanism in the exhaust pipe 100 includes a first silencer 111 and a second silencer 112. The first silencer 111 is located at the lower intake end 101 of the exhaust pipe 100 and is radially inserted along the exhaust pipe 100. The exhaust gas enters the exhaust pipe 100 radially through the first silencer 111 and moves upward to the second silencer 112. Further, an exhaust silencer 104 is arranged on the exhaust pipe 100, and the second silencer 112 is arranged in the exhaust silencer 104. The second silencer 112 is coaxially arranged with the exhaust pipe 100, and the exhaust gas enters the second silencer 112 axially and flows out radially. The inner diameter of the exhaust silencer 104 is designed to be much larger than that of the exhaust pipe 100, so there is enough space to accommodate the exhaust gas flowing out of the second silencer 112.

[0028] An oil filter 113 is also arranged between the first silencer 111 and the second silencer 112. The oil filter 113 adopts a wire mesh oil filter structure. Since the exhaust gas contains oil and gas mixture discharged from the compressor, the oil filter 113 intercepts the oil in the mixture. The intercepted oil gradually flows downward along the exhaust pipe 100 and finally flows out from the oil outlet hole 103 at the bottom. In addition, an oil drain pipe 105 is also arranged on the outside of the exhaust pipe 100, which communicates with the exhaust silencer 104 to remove the oil.

[0029] Further, a baffle plate 106 is obliquely arranged between the oil drain hole 103 and the first muffler 111. The oblique arrangement helps to concentrate the oil flowing downward along the exhaust pipe 100 to one side. The baffle plate 106 is provided with at least one through hole 107 for the oil to flow into the bottom after passing through.

[0030] The first muffler 111 and the second muffler 112 filter the low-frequency noise of 0-100 Hz transmitted by the compressor through the densely distributed hole structure. Preferably, the hole opening ratio of the peripheral surface of the first muffler 111 is 8.6%, and the hole opening ratio of the peripheral surface of the second muffler 112 is 7.2%.
