Description

Technical Field

[0001] This invention relates to the field of compressor technology, and more specifically, to an exhaust assembly and a compressor. Background Technology

[0002] Traditional exhaust assemblies typically consist of a valve plate and a baffle. One end of the valve plate is fixedly connected to the valve seat, and the other end is located above the sealing ring of the exhaust port. When the gas in the compression chamber reaches the exhaust pressure, the valve plate moves upward under the impact of the high-pressure gas, initiating the exhaust process. After the exhaust process is completed, the pressure inside the chamber decreases, and the valve plate closes the exhaust passage under the pressure difference between the inside and outside and its own elasticity, completing the exhaust action.

[0003] The problems with traditional exhaust assembly structures are as follows: when the valve plate is open, the valve plate head will hit the baffle due to excessive exhaust pressure, generating impact and noise; when the valve plate is closed, the valve plate head will hit the valve seat due to large external back pressure. Repeated exhaust processes can cause the valve plate to break, affecting the operation of the compressor. Summary of the Invention

[0004] The problem solved by this invention is how to improve the technical problem that exhaust components are easily damaged and prone to abnormal noise in the prior art.

[0005] To address the above problems, the present invention provides an exhaust assembly for use in a compressor, the exhaust assembly comprising a main body and a hinge assembly;

[0006] The main body is provided with a first sliding groove and a first exhaust hole. One end of the first sliding groove is used to connect to the compression chamber of the compressor, and the other end is used to connect to the exhaust chamber of the compressor. One end of the first exhaust hole is used to connect to the compression chamber, and the other end is used to connect to the exhaust chamber. The first sliding groove and the first exhaust hole are arranged at intervals.

[0007] The hinge assembly includes a first movable member, a second movable member, and a linkage member; the first movable member is movably disposed within the first slide groove; the second movable member is movably connected to the main body; one end of the linkage member is connected to the first movable member, and the other end is connected to the second movable member;

[0008] The first movable member is used to slide in the first groove when there is a pressure difference between the air pressure in the compression chamber and the air pressure in the exhaust chamber, so as to drive the second movable member to open the first exhaust port when the air pressure in the compression chamber is higher than the air pressure in the exhaust chamber, or to close the first exhaust port when the air pressure in the compression chamber is lower than the air pressure in the exhaust chamber.

[0009] The advantages of the exhaust assembly provided by this invention compared to the prior art include:

[0010] When the air pressure in the compression chamber is higher than that in the exhaust chamber, the first movable member slides along the first slide groove, thereby causing the second movable member to slide along the main body through the action of the linkage member, opening the first exhaust port. This connects the exhaust chamber and the compression chamber, allowing gas from the compression chamber to flow into the exhaust chamber. When the air pressure in the compression chamber is lower than that in the exhaust chamber, the first movable member slides along the first slide groove, and the second movable member slides along the main body through the action of the linkage member, closing the first exhaust port. This prevents gas from flowing back into the compression chamber from the exhaust chamber. Due to the linkage between the first and second movable members, the first and second movable members can open or close the first exhaust port by sliding, preventing collisions between them and other parts. This not only avoids damage to the first and second movable members but also reduces the problem of abnormal noise. Therefore, this exhaust assembly improves the technical problems of easy damage and abnormal noise in existing exhaust assemblies.

[0011] Optionally, the main body is further provided with a first air chamber, which is used to communicate with the compression chamber; the first slide groove and the first exhaust hole are both connected to the first air chamber.

[0012] Optionally, the second movable member is movably connected to the side of the main body away from the first air chamber, and the moving direction of the second movable member is set at an angle to the moving direction of the first movable member. Because the moving directions of the first and second movable members are at an angle, the moving speed and distance of the second movable member can be reduced during the process of the first movable member driving the second movable member through the linkage, thereby further improving the technical problem of the second movable member colliding with other parts and generating abnormal noise.

[0013] To ensure that the second movable component can move stably, optionally, the main body is provided with a second slide rail, and the second movable component is provided with a second slide groove, and the second slide rail and the second slide groove are slidably engaged.

[0014] Optionally, the linkage is a rigid structure, with one end hinged to the first movable member and the other end hinged to the second movable member. Connecting the first and second movable members with a rigid linkage improves the sensitivity of the first movable member in driving the second movable member to slide, and also enhances the stability of the linkage between the first and second movable members.

[0015] To prevent the first movable member from disengaging from the first slide groove, the exhaust assembly may optionally include a stop block disposed within the first slide groove and used to abut against the first movable member to restrict the first movable member from moving toward the compression chamber.

[0016] To reduce noise, the main body may optionally include a second air chamber, with the first slide groove and the first exhaust port both communicating with the second air chamber. The exhaust assembly also includes a baffle that covers the second air chamber. A second exhaust port is provided on the baffle, communicating with the second air chamber. When gas is discharged from the first exhaust port, the sudden drop in gas pressure and the increased space for flow cause mutual interference and reflection of the airflow, thereby achieving noise reduction.

[0017] Optionally, the first exhaust port is opened at one end of the baffle, and the second exhaust port is opened at the other end of the baffle.

[0018] In order to effectively expel the gas in the second air chamber, the second exhaust port may optionally be inclined.

[0019] A compressor includes an exhaust assembly. The exhaust assembly includes a body and a hinge assembly.

[0020] The main body is provided with a first sliding groove and a first exhaust hole. One end of the first sliding groove is used to connect to the compression chamber of the compressor, and the other end is used to connect to the exhaust chamber of the compressor. One end of the first exhaust hole is used to connect to the compression chamber, and the other end is used to connect to the exhaust chamber. The first sliding groove and the first exhaust hole are arranged at intervals.

[0021] The hinge assembly includes a first movable member, a second movable member, and a linkage member; the first movable member is movably disposed within the first slide groove; the second movable member is movably connected to the main body; one end of the linkage member is connected to the first movable member, and the other end is connected to the second movable member;

[0022] The first movable component is used to slide in the first groove when there is a pressure difference between the air pressure in the compression chamber and the air pressure in the exhaust chamber, so as to drive the second movable component to open or close the first exhaust port.

[0023] The compressor provided by the present invention uses the above-mentioned exhaust assembly, and the beneficial effects of the compressor compared with the prior art are the same as the beneficial effects of the exhaust assembly provided compared with the prior art, which will not be repeated here.

Detailed Implementation

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] This application provides a compressor (not shown) for compressing gaseous refrigerant to discharge it at high temperature and pressure, thereby allowing the refrigerant to circulate in the refrigeration system and enabling the system to provide air conditioning to a designated area. Of course, during the circulation of the refrigerant in the refrigeration system, gaseous refrigerant is drawn into the compressor for repeated compression and discharge.

[0036] The compressor contains a compression chamber (not shown) and an exhaust chamber (not shown). The compression chamber draws in gaseous refrigerant from the refrigeration system and compresses it. The compressed refrigerant is then directed to the exhaust chamber, where it exits the compressor and enters the refrigerant circulation loop. During the compression process, the pressure within the compression chamber fluctuates. When the pressure increases, the high-pressure refrigerant is directed to the exhaust chamber; conversely, when the pressure decreases, it is crucial to prevent refrigerant from flowing back into the compression chamber.

[0037] In existing technology, compressors use a valve plate and a baffle to form a one-way valve. When the pressure in the compression chamber is higher than that in the discharge chamber, the valve plate opens to allow refrigerant in the compression chamber to flow into the discharge chamber; when the pressure in the compression chamber is lower than that in the discharge chamber, the valve plate closes to prevent refrigerant backflow. However, when the valve plate is closed, the large pressure difference causes the valve plate to strike the baffle, resulting in abnormal noise. Furthermore, the frequent pressure changes in the compression chamber cause the valve plate to open and close frequently, making it prone to damage.

[0038] Based on this, please refer to the following: Figure 1 In order to improve the above-mentioned problems, in other words, in order to improve the technical problem that the exhaust assembly 10 in the prior art is easily damaged and easily causes abnormal noise, the exhaust assembly 10 of this application and the compressor using the exhaust assembly 10 are provided.

[0039] The exhaust assembly 10 is installed between the exhaust chamber and the compression chamber. When the gaseous refrigerant in the compression chamber is compressed into a high-temperature, high-pressure refrigerant, the high-pressure refrigerant can be introduced into the exhaust chamber through the exhaust assembly 10. When the gaseous refrigerant in the compression chamber is depressurized to draw gaseous refrigerant from the refrigeration system, the exhaust assembly 10 is closed to prevent the refrigerant in the exhaust chamber from flowing back into the compression chamber.

[0040] Please refer to the following: Figure 1 and Figure 2In the embodiments of this application, the exhaust assembly 10 includes a main body 100 and a hinge assembly 200. The main body 100 is used to install inside the compressor, such that the exhaust chamber and the compression chamber are located on opposite sides of the main body 100. Furthermore, the main body 100 has a first sliding groove 110 and a first exhaust port 120. One end of the first sliding groove 110 is connected to the compression chamber of the compressor, and the other end is connected to the exhaust chamber of the compressor. One end of the first exhaust port 120 is connected to the compression chamber, and the other end is connected to the exhaust chamber; the first sliding groove 110 and the first exhaust port 120 are spaced apart. The hinge assembly 200 includes a first movable member 210, a second movable member 230, and a linkage member 220; the first movable member 210 is movably disposed within the first sliding groove 110; the second movable member 230 is movably connected to the main body 100; one end of the linkage member 220 is connected to the first movable member 210, and the other end is connected to the second movable member 230. The first movable member 210 is used to slide in the first slide groove 110 when there is a pressure difference between the air pressure in the compression chamber and the air pressure in the exhaust chamber, so as to drive the second movable member 230 to open the first exhaust port 120 when the air pressure in the compression chamber is higher than the air pressure in the exhaust chamber, or to close the first exhaust port 120 when the air pressure in the compression chamber is lower than the air pressure in the exhaust chamber.

[0041] As described above, when the air pressure in the compression chamber is higher than that in the exhaust chamber, the first movable member 210 slides along the first sliding groove 110, thereby causing the second movable member 230 to slide along the main body 100 through the driving action of the linkage member 220, so as to open the first exhaust port 120. At this time, the first exhaust port 120 can connect the exhaust chamber and the compression chamber, and the gas in the compression chamber can be introduced into the exhaust chamber, such as... Figure 2 When the air pressure in the compression chamber is lower than the air pressure in the exhaust chamber, the first movable member 210 slides along the first slide groove 110, and the second movable member 230 slides along the main body 100 through the driving action of the linkage member 220, thereby closing the first exhaust port 120. This prevents the gas in the exhaust chamber from flowing back into the compression chamber. Figure 1 Due to the linkage between the first movable member 210 and the second movable member 230, the first movable member 210 and the second movable member 230 can slide to open or close the first exhaust port 120. This prevents the first movable member 210 and the second movable member 230 from colliding with other parts, thus avoiding the problem of easy damage to the first movable member 210 and the second movable member 230, and also improving the problem of abnormal noise. Based on this, the exhaust assembly 10 can improve the technical problems of easy damage and abnormal noise in the prior art.

[0042] It is worth noting that when the gas pressure in the compression chamber is higher than that in the exhaust chamber, the gas pressure at the end of the first slide groove 110 near the compression chamber is higher than that at the end near the exhaust chamber. This causes the gas near the compression chamber to exert a force on the first movable member 210, moving it away from the compression chamber. This movement, via the linkage 220, drives the second movable member 230, which in turn opens the first exhaust port 120, allowing gas from the compression chamber to be introduced into the exhaust chamber. After the refrigerant is introduced from the compression chamber into the exhaust chamber, the compression chamber draws refrigerant from the refrigeration system. At this point, the gas pressure in the compression chamber is lower than that in the exhaust chamber. This causes the first movable member 210 to be subjected to a force from the exhaust chamber side, moving it closer to the compression chamber. Simultaneously, this moves the linkage 220 and the second movable member 230, allowing the second movable member 230 to close the first exhaust port 120, thus preventing refrigerant from flowing back into the compression chamber.

[0043] Optionally, in an embodiment of this application, the main body 100 is further provided with a first air chamber 130, which is used to communicate with the compression chamber; the first slide groove 110 and the first exhaust hole 120 are both connected to the first air chamber 130.

[0044] The first gas chamber 130 can be divided into an inlet section 131 and a pressure section 132. The inlet section 131 is used to connect to the compression chamber. The extension direction of the pressure section 132 is set at an angle to the extension direction of the inlet section 131, and the inlet section 131 is located at one end of the pressure section 132. This allows the gaseous refrigerant from the compression chamber to pass through the inlet section 131 and then enter the pressure section 132 when it is introduced into the first gas chamber 130. This prevents the high-pressure gaseous refrigerant from directly impacting the first moving part 210, thus preventing damage to the first moving part 210 due to excessive force. At the same time, the gas is reflected multiple times in the inlet section 131 and the pressure section 132, which can achieve the purpose of noise reduction.

[0045] In some embodiments of this application, the first groove 110 and the first exhaust port 120 are located at opposite ends of the pressure section 132. Optionally, the inlet section 131 can be located at one end of the pressure section 132 corresponding to the first groove 110, thereby preventing high-pressure gaseous refrigerant from directly entering the first exhaust port 120. This allows the gaseous refrigerant to undergo multiple reflections before entering the first exhaust port 120, achieving noise reduction. It should be understood that in other embodiments of this application, the inlet section 131 can also be located at other positions within the pressure section 132.

[0046] It should be noted that the "reflection" mentioned above refers to the situation where the flow direction of the gaseous refrigerant changes when it impacts the inner peripheral wall of the first gas chamber 130 during the flow of the gaseous refrigerant along the inlet section 131 and the gas pressure section 132.

[0047] Of course, in other embodiments of this application, the inlet section 131, the air pressure section 132, or the entire first air chamber 130 may be omitted.

[0048] Please refer to the following: Figure 3 , Figure 4 and Figure 5 To ensure the sliding stability between the first movable member 210 and the first slide groove 110, a first slide rail 112 is provided on the inner wall of the first slide groove 110, and the extending direction of the first slide rail 112 is the same as the opening direction of the first slide groove 110; correspondingly, a sliding groove 211 is provided on the first movable member 210. Through the sliding cooperation of the first slide rail 112 and the sliding groove 211, the stability of the first movable member 210 sliding along the first slide groove 110 can be improved. It should be understood that in other embodiments of this application, the sliding groove 211 can be formed on the inner wall of the first slide groove 110, and the first slide rail 112 can be provided on the first movable member 210; of course, the first slide rail 112 and the sliding groove 211 can also be omitted.

[0049] Additionally, please see Figure 6 To prevent the first movable member 210 from dislodging from the first slide groove 110, optionally, in some embodiments of this application, the exhaust assembly 10 further includes a stop block 111. The stop block 111 is disposed within the first slide groove 110 and is used to abut against the first movable member 210 to restrict the movement of the first movable member 210 toward the compression chamber. The stop block 111 protrudes from the inner wall of the first slide groove 110, thereby allowing the first movable member 210 to abut against the stop block 111 as it moves toward the first air chamber 130. Thus, by restricting the movement of the first movable member 210 by the stop block 111, the first movable member 210 can be prevented from dislodging from the first slide groove 110.

[0050] In some embodiments of this application, the first slide groove 110 is a square slot, and the shape of the first movable member 210 is adapted to the shape of the first slide groove 110. This allows the first slide groove 110 to restrict the rotation of the first movable member 210, ensuring its stability. Of course, in other embodiments of this application, the first slide groove 110 can also adopt other shapes, such as circular, elliptical, trapezoidal, or rhomboid. Furthermore, when the first slide rail 112 and the slide groove 211 are provided, the cooperation between the first slide rail 112 and the slide groove 211 can also prevent the first movable member 210 from rotating.

[0051] It should be noted that in some embodiments of this application, the stop 111 and the first slide groove 110 are at a certain distance from the opening of the first air chamber 130. This ensures that even when the first movable member 210 is against the stop 111, a portion of the first slide groove 110 remains unoccupied. This facilitates the entry of gas from the first air chamber 130 into the first slide groove 110 and provides force to the first movable member 210, thereby improving the reaction speed and sensitivity of the first movable member 210 when the air pressure in the compression chamber is higher than that in the exhaust chamber. Of course, in other embodiments of this application, the stop 111 may also be located at the opening of the first slide groove 110.

[0052] It is worth noting that in some other embodiments, the diameter of the end of the first slide groove 110 near the first air chamber 130 is reduced to provide a limiting effect to the first movable member 210. This can also be regarded as setting a stop 111 inside the first slide groove 110.

[0053] In some embodiments of this application, the second movable member 230 is movably connected to the side of the main body 100 away from the first air chamber 130. At the same time, the linkage member 220 is also disposed on the side of the main body 100 away from the first air chamber 130. This allows the compression chamber to apply an action to the first movable member 210 under high pressure, thereby facilitating the movement of the first movable member 210 and the second movable member 230.

[0054] Furthermore, the moving direction of the second movable member 230 is set at an angle to the moving direction of the first movable member 210. Based on this, during the movement of the second movable member 230 driven by the first movable member 210 via the linkage 220, the moving speed and distance of the second movable member 230 can be reduced, thereby further improving the technical problem of the second movable member 230 colliding with other parts and generating abnormal noise. Of course, to ensure that the first movable member 210 can drive the second movable member 230 during its movement, one end of the linkage 220 is movably connected to the first movable member 210, and the other end of the linkage 220 is movably connected to the second movable member 230. Thus, during the sliding of the first movable member 210 along the first slide groove 110, the end of the linkage 220 not only moves along the first slide groove 110 with the first movable member 210, but also rotates along the first movable member 210, thereby facilitating the movement of the second movable member 230 by the linkage 220.

[0055] It should be noted that the movable connection between the linkage 220 and the first movable component 210 and the second movable component 230 allows the first movable component 210 and the second movable component 230 to move in different directions. Based on this, the positional requirements for the first movable component 210 and the second movable component 230 can be reduced, and their positions can be adjusted according to actual conditions, thus reducing manufacturing and design costs.

[0056] It should be understood that in other embodiments of this application, the arrangement of the first movable member 210 and the second movable member 230 may also differ. For example, if the first movable member 210 and the second movable member 230 move in the same direction, the connection between the linkage 220 and the first movable member 210 and the second movable member 230 can be a fixed connection. Alternatively, if the first movable member 210 and the second movable member 230 move in opposite directions, the linkage 220 can be configured as a lever structure to achieve the purpose of the first movable member 210 driving the second movable member 230 to move.

[0057] Optionally, in some embodiments of this application, the linkage 220 is a rigid structure, with one end of the linkage 220 hinged to the first movable member 210 and the other end hinged to the second movable member 230. The rigid structure means that the linkage 220 itself is not prone to elastic deformation, thereby improving the sensitivity of the first movable member 210 in driving the second movable member 230 to slide, and also improving the stability of the linkage between the first movable member 210 and the second movable member 230.

[0058] It should be noted that, in the embodiments of this application, the first movable member 210 and the linkage member 220 are generally rod-shaped structures, and the second movable member 230 is generally block-shaped. The first movable member 210, the linkage member 220 and the second movable member 230 together form a multi-link structure. During the sliding of the first movable member 210 along the first slide groove 110, the linkage member 220 is driven by the first movable member 210, and the linkage member 220 pulls or pushes the second movable member 230 to slide along the main body 100, thereby opening or closing the first exhaust port 120.

[0059] Furthermore, since the linkage 220 is rod-shaped, when the first movable member 210 moves a certain distance away from the compression chamber, the moving directions of the linkage 220 and the second movable member 230 form a large angle. At this time, the component force of the linkage 220 on the second movable member 230 in its moving direction gradually decreases, while the component force in the direction perpendicular to the moving direction of the second movable member 230 gradually increases. This increases the friction between the second movable member 230 and the second slide rail 231, causing the second movable member 230 to self-lock. In other words, by setting the rigid linkage 220, and simultaneously setting the moving direction of the first movable member 210 and the moving direction of the second movable member 230 at an angle, the first movable member 210, the linkage 220, and the second movable member 230 can form a self-locking mechanism when the first movable member 210 is a sufficiently long distance away from the compression chamber. This can prevent the first movable member 210 from dislodging from the first slide groove 110 and also prevent the second movable member 230 from dislodging from the second slide rail 231.

[0060] Additionally, please refer to the following: Figure 3 and Figure 7 To ensure the stable sliding of the second movable member 230 along the main body 100, in some embodiments of this application, a second slide rail 231 is provided on the main body 100, and a second slide groove 232 is provided on the second movable member 230. The second slide rail 231 and the second slide groove 232 are slidably engaged. The engagement of the second slide rail 231 and the second slide groove 232 not only provides guidance for the second movable member 230, allowing it to move stably along a predetermined direction to stably open or close the first exhaust port 120, but also, in embodiments of this application, the width of the second slide rail 231 gradually increases from the side closer to the main body 100 to the side farther away from the main body 100. This allows the second slide rail 231 to provide a limiting function for the second movable member 230 when engaged with the second slide groove 232, preventing the second movable member 230 from disengaging from the second slide rail 231 in a direction perpendicular to it, thereby ensuring the sliding stability of the second movable member 230. It should be understood that in other embodiments of this application, the second slide rail 231 may also be provided on the second movable member 230, and correspondingly, a second slide groove 232 is provided on the main body 100.

[0061] Additionally, please refer to the embodiments in this application. Figure 1 , Figure 2 and Figure 8The main body 100 is also provided with a second air chamber 140. The first slide groove 110 and the first exhaust port 120 are both connected to the second air chamber 140. The exhaust assembly 10 also includes a baffle 300, which covers the second air chamber 140. The baffle 300 has a second exhaust port 310, which is connected to the second air chamber 140 and is used to communicate with the exhaust chamber. It should be noted that the linkage 220, the second movable member 230, and part of the first movable member 210 are all located in the second air chamber 140. This can prevent the first movable member 210, the linkage 220, and the second movable member 230 from being affected by other parts during their movement, thereby ensuring the stability of the linkage between the first movable member 210, the linkage 220, and the second movable member 230. In addition, due to the provision of the second air chamber 140, when the gas is discharged from the first exhaust port 120, the gas pressure drops sharply and the space for flow increases, causing the airflow to interfere with and reflect each other, thereby achieving the purpose of noise reduction.

[0062] Optionally, the first exhaust port 120 is opened at one end facing the baffle 300, and the second exhaust port 310 is opened at the other end of the baffle 300. In other words, in some embodiments of this application, the first groove 110 and the first exhaust port 120 are respectively located at opposite ends of the baffle 300, while the second exhaust port 310 is opened at the end of the baffle 300 near the first groove 110. This allows the airflow from the first exhaust port 120 to be reflected multiple times before being discharged from the second exhaust port 310 during the exhaust process, thereby achieving noise reduction. It should be understood that in other embodiments of this application, the second exhaust port 310 may also be opened at other locations on the baffle 300, such as the middle of the baffle 300.

[0063] In addition, in some embodiments of this application, multiple second exhaust holes 310 may be provided, with the multiple second exhaust holes 310 spaced apart on the baffle 300. By setting the number of second exhaust holes 310 to multiple, the aperture of the multiple second exhaust holes 310 can be made smaller, thereby reducing the speed of the airflow exiting from the second exhaust holes 310, which can also achieve the purpose of reducing noise. It should be understood that in other embodiments of this application, only one second exhaust hole 310 may be provided.

[0064] To facilitate exhaust from the second exhaust port 310, in some embodiments of this application, the second exhaust port 310 is inclined. It should be noted that the second exhaust port 310 is inclined such that one end of the second exhaust port 310 connecting to the second air chamber 140 is inclined towards the first exhaust port 120. This makes the second exhaust port 310 approximately oriented towards the first exhaust port 120, thereby facilitating the exhaust flow from the second exhaust port 310 when airflow flows from the first exhaust port 120 to the second exhaust port 310. It should be understood that in other embodiments, the inclined arrangement of the second exhaust port 310 may be omitted.

[0065] In summary, the exhaust assembly 10 and compressor provided in this embodiment can, when the air pressure in the compression chamber is higher than the air pressure in the exhaust chamber, allow the first movable member 210 to slide along the first slide groove 110, thereby causing the second movable member 230 to slide along the main body 100 through the driving action of the linkage member 220, thus opening the first exhaust port 120. This allows the first exhaust port 120 to connect the exhaust chamber and the compression chamber, allowing gas from the compression chamber to be introduced into the exhaust chamber. When the air pressure in the compression chamber is lower than the air pressure in the exhaust chamber, the first movable member 210 slides along the first slide groove 110, and the second movable member 230 slides along the main body 100 through the driving action of the linkage member 220, thus closing the first exhaust port 120 and preventing gas from the exhaust chamber from flowing back into the compression chamber. Due to the linkage between the first movable member 210 and the second movable member 230, the first movable member 210 and the second movable member 230 can slide to open or close the first exhaust port 120. This prevents the first movable member 210 and the second movable member 230 from colliding with other parts, avoiding the problem of easy damage to the first movable member 210 and the second movable member 230, and also improving the problem of abnormal noise. Based on this, the exhaust assembly 10 can improve the technical problems of easy damage and abnormal noise in the prior art. In addition, the second air chamber 140 can also provide noise reduction for the exhaust from the first exhaust port 120, thereby reducing the noise generated by the exhaust assembly 10.

[0066] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
