DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] In the description of the present application, it should be understood that the orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" and the like indicate the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, without making the opposite statement, these orientation words do not indicate and imply that the indicated device or element must have a specific orientation or be constructed and operated in a specific orientation, therefore it cannot be understood as a limitation on the protection scope of the present application; the orientation words "inner, outer" refer to the inner and outer of the contour of each component itself.

[0026] For the convenience of description, spatial relative terms such as "on", "above", "upper surface", "upper" and the like can be used to describe the spatial position relationship of one device or feature with other devices or features as shown in the drawings. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation of the device described in the drawings. For example, if the device in the drawings is inverted, the device described as "above" or "on" other devices or structures will be positioned "below" or "under" other devices or structures.

[0027] In combination with the drawings shown in Figure 1 and Figure 2 According to the embodiments of the present application, a valve group assembly is provided, which comprises a valve plate 1 and a valve piece 2; the valve piece 2 is installed on the valve plate 1, at least three exhaust holes 101 are arranged on the valve plate 1, at least a first reed valve 21, a second reed valve 22 and a third reed valve 23 are arranged on the valve piece 2, the first reed valve 21, the second reed valve 22 and the third reed valve 23 are respectively arranged on the corresponding exhaust holes 101; taking the end surface of the valve piece 2 as a projection surface, the first reed valve 21 and the third reed valve 23 are arranged in the same direction in the first direction, the second reed valve 22 is arranged between the first reed valve 21 and the third reed valve 23, and the second reed valve 22 is arranged in the opposite direction in the first direction.

[0028] Specifically, the first direction is the vertical direction of the end face. When the exhaust port 101 exhausts, all three exhaust ports 101 exhaust simultaneously. The refrigerant impacts the first reed valve 21, the second reed valve 22, and the third reed valve 23, causing them to lift upwards. When intake occurs, the first reed valve 21, the second reed valve 22, and the third reed valve 23 cover the exhaust port 101. The second reed valve 22 is positioned between the first reed valve 21 and the third reed valve 23. Although the second reed valve 22 is positioned in the opposite direction in the first direction, it will not affect whether the second reed valve 22 covers or opens the exhaust port 101.

[0029] In this embodiment, three reed valves are provided, with one of them arranged in reverse. This structure makes full use of the design space and ensures that the valve plate's stiffness and natural frequency are compatible with the compressor's operating speed. The three-hole exhaust port structure reduces the occurrence of delayed closure of the exhaust valve, which is beneficial to improving the compressor's cooling capacity and performance. It also significantly increases the gas flow area, reduces the speed at which the exhaust valve impacts the valve port, and improves the reliability of the valve assembly. By providing multiple exhaust holes 101 on the valve plate 1 and covering them with reed valves, the refrigerant discharge can be precisely controlled. Each reed valve can operate independently, thereby managing different refrigerant paths. The second reed valve 22 is located between the first reed valve 21 and the third reed valve 23, and the second reed valve 22 is arranged in reverse in the first direction, which makes full use of the limited space on the valve plate 2.

[0030] See also Figure 1 and Figure 2 As shown, the first reed valve 21, the second reed valve 22 and the third reed valve 23 each include a head 201 and a waist 202. One end of the waist 202 is connected to the valve plate 2, and the other end of the waist 202 is connected to the head 201. The waist 202 of the second reed valve 22 is arranged in the opposite direction in the first direction. The head 201 of the second reed valve 22 is located between the head 201 of the first reed valve 21 and the head 201 of the third reed valve 23.

[0031] Specifically, when the exhaust port 101 exhausts air, the waist 202 drives the head 201 to lift up. When inhaling air, the head 201 covers the exhaust port 101. Since the cross-section of the head 201 is larger than the cross-sectional area of ​​the waist 202, if three reed valves are arranged side by side, the valve plate 2 needs to have a larger area. In this embodiment, the head 201 of the second reed valve 22 is located between the head 201 of the first reed valve 21 and the head 201 of the third reed valve 23, which means that the heads 201 are staggered.

[0032] In the embodiment, the heads 201 are misalignedly connected, which can save the area of the valve plate 2, so that more reed valves can be arranged in limited space, improving the space utilization, and the misaligned heads 201 can make each reed valve be independently controlled, improving the flexibility and response speed of the valve in controlling the fluid, and the flow of the refrigerant can be quickly adjusted under different working conditions.

[0033] Referring to Figure 1 and Figure 2 As shown in the drawings, taking the end surface of the valve plate 2 as the projection surface, the cross-sectional area of the head 201 of the first reed valve 21 is equal to that of the third reed valve 23, and the cross-sectional area of the head 201 of the second reed valve 22 is greater than or equal to that of the first reed valve 21.

[0034] In the embodiment, the cross-sectional areas of the heads 201 of the first reed valve 21 and the third reed valve 23 are equal, which helps to provide the same fluid dynamics characteristics at the two positions and maintain the symmetry of the refrigerant flow, while the cross-sectional area of the head 201 of the second reed valve 22 is greater than or equal to that of the first reed valve 21 and the third reed valve 23, which means that the second reed valve 22 can handle a larger refrigerant flow or provide stronger refrigerant control capability when needed. By adjusting the cross-sectional areas of the heads 201 of different reed valves, the pressure distribution inside the valve group can be optimized, and in particular, in the case of reverse arrangement of the second reed valve 22, the larger cross-sectional area helps to provide better pressure buffering when the refrigerant pressure changes.

[0035] Referring to Figure 1 and Figure 2 As shown in the drawings, the waists 202 of the first reed valve 21, the second reed valve 22 and the third reed valve 23 are independently arranged on the valve plate 2.

[0036] Specifically, the waists 202 of the first reed valve 21, the second reed valve 22 and the third reed valve 23 are independently arranged on the valve plate 2, that is, the heads 201 of the first reed valve 21, the second reed valve 22 and the third reed valve 23 are independently lifted or covered to cover the exhaust holes 101.

[0037] In this embodiment, the limited space on the exhaust valve can be fully utilized, and the stiffness and strength of each reed valve can be independently controlled through the waist width and valve line length of the reed valve. When setting, the stiffness and strength of each reed valve can be kept as close as possible to facilitate simultaneous opening and closing of each reed valve. Independent setting of each reed valve allows individual control of each exhaust port 101, which means that the opening and closing of each exhaust port 101 can be precisely adjusted as needed, thereby achieving more precise refrigerant control. In a multi-valve setting, independently set reed valves provide higher operational flexibility, allowing independent adjustment of the state of each reed valve according to different operating conditions or refrigerant characteristics to adapt to different operating requirements. If one of the reed valves fails, independent setting means that the other reed valves can still work normally, thereby improving the reliability and fault tolerance of the entire system. Independently controlled reed valves can more accurately manage refrigerant flow, reduce refrigerant kinetic losses, and improve the efficiency of refrigerant flow.

[0038] Referring to Figure 1 and Figure 2 As shown, the centers of the three exhaust ports 101 are arranged in an arc on the valve plate 1, and the geometric centers of the head portions 201 of the first, second, and third reed valves 21, 22, and 23 are arranged in an arc.

[0039] In this embodiment, by arranging the exhaust ports 101 and the reed valve head portions 201 in an arc, the pressure distribution of the refrigerant on the valve plate 1 can be made more uniform, reducing local high-pressure areas and thereby reducing refrigerant kinetic losses and noise.

[0040] As a specific implementation, the number of exhaust ports can be set to be greater than or equal to 3, and the mounting method of the valve plate 2 is not limited to screw connection, but can also be riveting or welding on the valve plate 1.

[0041] Referring to Figures 1 to 3 As shown, a cylinder head assembly includes a valve group assembly and a cylinder head 3, the valve group assembly being the valve group assembly described above, and the valve group assembly is arranged in the cylinder head 3. When the valve group assembly is in a first state, one side of the first, second, and third reed valves 21, 22, and 23 is respectively covered on the corresponding exhaust port 101, and the other side of the first, second, and third reed valves 21, 22, and 23 is away from the cylinder head 3. When the valve group assembly is in a second state, one side of the first, second, and third reed valves 21, 22, and 23 is respectively away from the corresponding exhaust port 101, and the other side of the first, second, and third reed valves 21, 22, and 23 abuts against the cylinder head 3.

[0042] Specifically, when the valve group assembly is in the first state, i.e., the exhaust hole 101 is not exhausting, one side of the first reed valve 21, the second reed valve 22 and the third reed valve 23 is respectively covered on the corresponding exhaust hole 101, and the other side does not abut against the cylinder cover 3; when the valve group assembly is in the second state, i.e., the exhaust hole 101 is exhausting, one side of the first reed valve 21, the second reed valve 22 and the third reed valve 23 respectively opens the corresponding exhaust hole 101, the waist part 202 of the reed valve drives the head part 201 to lift up, and the other side of the first reed valve 21, the second reed valve 22 and the third reed valve 23 abut against the cylinder cover 3.

[0043] In the embodiment, the lift limiter of the exhaust valve is cancelled, and the cylinder cover 3 plays a role of limiting the lift of the valve plate 2. The cancellation of the lift limiter can reduce the complexity of the valve group assembly and reduce the manufacturing and maintenance costs. By directly limiting the lift of the valve plate 2 through the cylinder cover 3, the overall structure of the compressor is simplified, and the lift limiter is one of the components that are easy to wear and damage in the compressor. By limiting the lift of the valve plate 2 through the cylinder cover 3, the risk of compressor shutdown caused by lift limiter failure can be reduced, and the reliability of the system can be improved.

[0044] For reference Figures 1 to 3 , the cylinder cover 3 is provided with a lift limiting seat. When the valve group assembly is in the second state, one side of the first reed valve 21, the second reed valve 22 and the third reed valve 23 away from the exhaust hole 101 abuts against the lift limiting seat.

[0045] In the embodiment, when the exhaust hole 101 is opened, the reed valve is lifted, and the reed valve abuts against the lift limiting seat. The lift limiting seat is used to limit the lifting height of the valve plate 2, so as to ensure that the reed valve does not move excessively when opening and closing the exhaust hole 101, thereby avoiding damage of the valve plate 2 due to excessive bending or stretching. By limiting the maximum lifting height of the reed valve, the rebound stress suffered by the reed valve during resetting can be reduced, the service life of the reed valve is prolonged, the lift limiting seat helps the valve plate 2 to reset in time, prevents excessive loss of gaseous refrigerant, and improves the working reliability of the compressor.

[0046] For reference Figures 1 to 3 As shown in the figure, the lift limiting seat includes a first support seat 401, a second support seat 402 and a third support seat 403. The first support seat 401, the second support seat 402 and the third support seat 403 are respectively arranged corresponding to the first reed valve 21, the second reed valve 22 and the third reed valve 23. One side of the first reed valve 21, the second reed valve 22 and the third reed valve 23 away from the exhaust hole 101 respectively abuts against the first support seat 401, the second support seat 402 and the third support seat 403.

[0047] In the embodiment, when the exhaust hole 101 is opened, the three reed valves are lifted, and the three reed valves abut against the three support seats respectively. Each reed valve is limited by the corresponding support seat, so that the lift of each reed valve can be more accurately controlled, ensuring that it moves within the set range and avoiding damage caused by excessive movement. Since each reed valve has an independent limiting seat, each reed valve can be independently controlled, improving the flexibility and response speed of the system.

[0048] For reference Figures 1 to 3 As shown in the figure, the first support seat 401, the second support seat 402 and the third support seat 403 are arranged at intervals on the cylinder head 3, and the gap between the first support seat 401, the second support seat 402 and the third support seat 403 forms an exhaust passage 404, which is S-shaped.

[0049] In the embodiment, the S-shaped exhaust passage 404 can increase the path length of the exhaust gas, which helps to reduce the exhaust noise. Because the airflow reflects and consumes energy in the passage, the noise propagation is reduced. The S-shaped passage can reduce the airflow interference between different exhaust holes 101 and improve the exhaust efficiency. Because the S-shaped arrangement can make the airflow flow more smoothly, it reduces the generation of vortex and turbulence, reduces the gas flow rate, and can effectively reduce the noise generated during the exhaust process of the compressor. Moreover, by arranging the support seats at intervals and forming the exhaust passage 404 between them, the structural stability of the cylinder head 3 can be enhanced, because such arrangement helps to evenly distribute the heat and pressure on the cylinder head 3.

[0050] For reference Figures 1 to 3 As shown in the figure, taking the end face of the valve plate 2 as the projection plane, the first support seat 401 and the third support seat 403 are arranged in the same direction in the second direction, and the second support seat 402 is arranged between the first support seat 401 and the third support seat 403, and the second support seat 402 is arranged in the opposite direction in the second direction. In other embodiments, the support seats in the cylinder head 3 can be arranged in other structures to reduce the gas flow rate.

[0051] In the embodiment, by arranging the first support seat 401 and the third support seat 403 in the same direction at both ends and arranging the second support seat 402 in the opposite direction in the middle, the support force on the valve plate 2 can be balanced, and the deformation or damage of the valve plate 2 caused by uneven force can be reduced.

[0052] A compressor comprising a cylinder head assembly, the cylinder head assembly being the cylinder head assembly described above.

[0053] It is easy for those skilled in the art to understand that the above advantageous modes can be freely combined and superimposed without conflict.

[0054] The above merely is the preferred embodiment of the present application, and does not limit the present application, and any modification, equivalent replacement and improvement etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application. The above is merely the preferred embodiment of the present application, and it should be pointed out that, for the ordinary skilled in the art, without departing from the technical principle of the present application, a number of improvements and modifications can be made, and these improvements and modifications shall be considered as the protection scope of the present application.
