Or the bottom end of the first oil leakage hole 13 is flush with the bottom wall of the first cavity 111, and the height difference between the bottom end of the first oil leakage hole 13 and the bottom wall of the first cavity 111 is eliminated, so that the outflow of lubricating oil is smoother. If the bottom end of the first oil drain hole 13 is higher than the bottom wall of the first cavity 111, the lubricating oil needs to accumulate to a certain height in the first cavity 111 to be drained through the first oil drain hole 13, and the drainage efficiency of the first oil drain hole 13 is reduced.
In an embodiment, referring to fig. 5 and 6 in combination, the cross-sectional areas of the first oil leakage hole 13 and the second oil leakage hole 24 are consistent or tapered along the length direction.
The cross-sectional area of the first oil drain hole 13 is kept uniform in the length direction, that is, the cross-sectional area of the first oil drain hole 13 is kept uniform in the front-rear direction, so that the lubricating oil can flow out at a uniform flow rate. The cross-sectional area of the second oil drain hole 24 is kept uniform in the length direction, that is, the cross-sectional area of the second oil drain hole 24 is kept uniform in the up-down direction, so that the lubricating oil can flow into the first chamber 111 at a uniform flow rate.
The cross-sectional area of the first oil leakage hole 13 is tapered along the length direction, that is, the cross-sectional area of the first oil leakage hole 13 gradually decreases from front to back, and the cross-sectional area of the front end of the first oil leakage hole 13 is larger than the cross-sectional area of the rear end, so that the guiding effect on the leakage process of lubricating oil can be achieved. The cross-sectional area of the second oil drain hole 24 is tapered along the length direction, that is, the cross-sectional area of the second oil drain hole 24 gradually decreases from top to bottom, and the cross-sectional area of the upper end of the second oil drain hole 24 is greater than the cross-sectional area of the lower end, so that the guiding effect on the leakage process of lubricating oil can be achieved.
In an embodiment, please refer to fig. 5 and fig. 6 in combination, wherein fig. 6 is a graph of the calculation result of acoustic power of different lengths of the first oil leakage hole and the second oil leakage hole in the muffler, wherein the abscissa is frequency in Hz, and the ordinate is acoustic power in dB. The four curves in fig. 6 are no first oil drain hole 13 and no second oil drain hole 24, the lengths of the first oil drain hole 13 and the second oil drain hole 24 being 2mm and the lengths of the first oil drain hole 13 and the second oil drain hole 24 being 5mm, respectively. It can be seen from the figure that the lengths of the first oil drain hole 13 and the second oil drain hole 24 are 5mm, and compared with the lengths of the first oil drain hole 13 and the second oil drain hole 24, the acoustic power is lower, the noise reduction capability is better, and the silencing performance of the silencer is better.
The hydraulic diameter refers to four times the ratio of the flow cross-sectional area to the perimeter. The shearing stress of the non-circular tube along the peripheral wall surface is not uniformly distributed, so that only the average value of the non-circular tube along the peripheral wall surface can be calculated. The expressions of the two cases are compared, and a comparison, namely A/P-r/2, can be intuitively obtained. Both sides are multiplied by 4 at the same time, with 4A/P-2 r (=d). Thus, the hydraulic diameter and the true diameter of the circular tube are equivalent in the hydraulic sense. If the first oil leakage hole 13 is a square hole or another hole, the hydraulic diameter of the round hole can be calculated according to the above formula.
When the cross-sectional area of the first oil leakage hole 13 is kept consistent along the length direction, the hydraulic diameter of the first oil leakage hole 13 is D1, and the length of the first oil leakage hole 13 is H1, wherein D1 is less than 2mm, and H1 is more than or equal to 5 (D1) 2.
In this embodiment, the hydraulic diameter of the first oil leakage hole 13 is defined as D1, and D1 is smaller than 2mm, where the hydraulic diameter of the first oil leakage hole 13 is smaller than 2mm, so as to ensure the silencing effect and avoid the influence of the excessive hydraulic diameter of the first oil leakage hole 13 on the silencing effect. The length of the first oil leakage hole 13 is H1, H1 is larger than or equal to 5 (D1) 2, that is, the minimum value of H1 is 5 (D1) 2, so that the first oil leakage hole 13 is prevented from being too short in length and insufficient in extending length, and the silencing effect of the first oil leakage hole 13 can be reduced.
When the cross-sectional area of the second oil leakage hole 24 is kept consistent in the up-down direction, the hydraulic diameter of the second oil leakage hole 24 is D2, and the length of the second oil leakage hole 24 is H2, wherein D2 is less than 2mm, and H2 is more than or equal to 5 (D2) 2.
In this embodiment, the hydraulic diameter of the second oil leakage hole 24 is defined as D2, and D2 is smaller than 2mm, where the hydraulic diameter of the second oil leakage hole 24 is smaller than 2mm, so as to ensure the silencing effect and avoid the influence of the excessive hydraulic diameter of the second oil leakage hole 24 on the silencing effect. The length of the second oil leakage hole 24 is H2, H2 is larger than or equal to 5 (D2) 2, that is, the minimum value of H2 is 5 (D2) 2, so that the condition that the length of the second oil leakage hole 24 is too short and the extending length is insufficient is avoided, and the silencing effect of the second oil leakage hole 24 can still be reduced.

When the compressor is operated, the gaseous refrigerant enters the first chamber 111 through the inlet pipe 14, and diffuses in the first chamber 111 to reduce the pulsation of the air flow of the portion, thereby realizing the primary noise reduction of the gaseous refrigerant. Then, the gaseous refrigerant enters the pipe body 21, and the gaseous refrigerant in the pipe body 21 enters the second cavity 112 through the through hole 211 and diffuses in the second cavity 112, thereby realizing the second-stage noise reduction of the gaseous refrigerant, and then enters the cylinder of the compressor from the outlet pipe 15. By performing two-stage noise reduction on the gaseous refrigerant, the sound deadening effect of the muffler 100 is effectively enhanced.
