[0038] See also Figure 1 and Figure 2An embodiment of the present invention provides a partition, which is applied to a liquid dispenser, wherein the partition 1 includes: a partition body 11, which is provided with at least one flow hole 111: an opening change member 12, which is movably arranged on the partition body 11, and the opening change member 12 can adjust the opening size of the flow hole 111 when it is active. In the present embodiment, at least one flow hole 111 is provided on the partition body 11, and the opening conversion member 12 is provided on the partition body 11, the opening conversion member 12 can be movable, and when it is movable, the opening size of the flow hole 111 can be adjusted as needed. If it is necessary to adjust the flow rate of the gas refrigerant or fluid according to different working conditions, there is no need to replace the entire partition 1, and the opening size of the flow hole 111 can be adjusted by moving the opening conversion member 12, thereby optimizing the flow state of the gas refrigerant or fluid, that is, when adjusting the different opening sizes of the flow hole 111, there is no need to re-open the mold of the partition 1, and the opening conversion member 12 can be directly controlled to move, which not only saves time and effort, but also reduces costs; and it can also effectively alleviate the pressure pulsation problem in the liquid distributor 2, thereby reducing the noise of the compressor 3 and improving the comfort of the air conditioner.

[0039] In this embodiment, the flow hole 111 of the partition 1 can be designed to be circular. In other embodiments, the flow hole 111 can also be designed to be elliptical, square or other shapes as needed.

[0040] Furthermore, the partition 1 further comprises: a driving member 13 connected to the partition body 11, the driving member 13 is drivingly connected to the opening change member 12, and is used to drive the opening change member 12 to move. In this embodiment, the driving member 13 is connected to the partition body 11 to ensure its stability and reliability during operation. The driving member 13 can be a motor, a cylinder, a screw or other device that can drive the opening change member 12 to move. Through the drive of the driving member 13, the opening change member 12 can be driven to perform corresponding movements on the partition body 11.

[0041] The main function of the driver 13 is to provide power to drive the opening changer 12 to move. When the internal state of the dispenser 2 changes, the driver 13 can respond in time and drive the opening changer 12 to adjust the opening size of the flow hole 111. By introducing the driver 13, the automatic control of the opening changer 12 is realized, which not only eliminates the tediousness and errors of manual adjustment, but also can accurately control the movement of the opening changer 12, thereby realizing the precise adjustment of the opening size of the flow hole 111, which is particularly important for occasions that require highly precise control of fluid flow or pressure distribution. At the same time, the driver 13 can be designed as a detachable and replaceable component, which is convenient for maintenance and upgrading when necessary.

[0042] It should be noted that the opening conversion member 12 is movably arranged on the partition body 11, that is, the opening conversion member 12 can be moved or adjusted on the partition body 11 in some way. The opening conversion member 12 can slide, swing, tilt or perform other forms of displacement on the partition body 11, so that the opening size of the flow hole 111 can be adjusted as needed, thereby increasing the flexibility of the design.

[0043] Specifically, the opening change member 12 can be rotatably arranged on the partition body 11, and the driving member 13 is used to drive the opening change member 12 to rotate. In this embodiment, the opening change member 12 can rotate on the partition body 11 around an axis on the partition body 11. This rotation mechanism allows the opening change member 12 to change its position relative to the flow hole 111 when receiving the driving force of the driving member 13, thereby adjusting the opening size of the flow hole 111 and ensuring that the opening change member 12 can be stably and smoothly rotated on the partition body 11. The rotation setting is more suitable for scenarios where there are precise requirements for the opening size of the flow hole 111, for example, it is necessary to strictly control the pressure pulsation signal, gas flow rate and liquid refrigerant fluid flow rate in the liquid distributor 2.

[0044] Furthermore, the opening conversion member 12 is provided with a connecting portion 121 and a shielding portion 122 connected to the connecting portion 121, the connecting portion 121 is connected to the driving member 13, the shielding portion 122 is provided on the surface of the partition body 11, and the shielding portion 122 does not cover, partially covers or completely covers the flow hole 111 to adjust the opening size of the flow hole 111.

[0045] In this embodiment, the connection part 121 is the interface part between the opening change member 12 and the driving member 13, which ensures that the opening change member 12 can be stably and reliably connected to the driving member 13, thereby driving the shielding part 122 to shield the flow hole 111 to varying degrees. The shielding part 122 is the part that directly acts on the flow hole 111 on the partition body 11, and adjusts the opening size of the flow hole 111 by changing its position relative to the flow hole 111.

[0046] like Figure 3 and Figure 4 As shown, the shielding portion 122 can be designed into different shapes and sizes to accommodate different sizes of flow holes 111 and different adjustment requirements. For example, the shielding portion 122 can be a circular structure, an elliptical structure, a square structure, or a plate with a complex contour, or a sliding member with a slide groove or a hole. The contact surface between the shielding portion 122 and the partition body 11 can be set to a smooth surface to reduce the resistance and wear when the fluid passes through. At the same time, the material of the shielding portion 122 should have sufficient strength and corrosion resistance to withstand the impact of the fluid and increase the service life.

[0047] The opening change member 12 drives the shielding member 122 to shield the flow hole 111 through the cooperation of the connection member 121 and the driving member 13. Specifically, when the driving member 13 receives a control signal, the connection member 121 receives a rotation signal, thereby driving the shielding member 122 to move relative to the flow hole 111, so as to not cover, partially cover or completely cover the flow hole 111, so as to adjust the opening size of the flow hole 111. Figure 2 is a schematic diagram showing that the shielding portion 122 completely covers the flow hole 111, Figure 5 is a schematic diagram showing that the shielding portion 122 partially covers the flow hole 111, Figure 6 It is a schematic diagram showing that the shielding portion 122 partially covers the flow hole 111 from another viewing angle.

[0048] In some embodiments, in order to achieve continuous or graded adjustment of the opening size of the flow hole 111 by the opening changer 12, a corresponding transmission mechanism or adjustment mechanism may be provided between the driver 13 and the opening changer 12. For example, transmission elements such as gears, screws, and cams are used to achieve precise blocking control of the flow hole 111 by the blocking portion 122. Specifically, power is transmitted by the mutual meshing of two or more gears. When the driver 13 drives a gear to rotate, another gear meshed with it will also rotate at a certain speed, thereby driving the opening changer 12 to rotate. Power is transmitted by the threaded fit of the screw and the nut. When the driver 13 drives the screw to rotate, the nut will move along the axial direction of the screw, thereby driving the opening changer 12 to rotate. Power is transmitted by the contact between the profile curve of the cam and the follower. When the driver 13 drives the cam to rotate, the profile curve of the cam will push the follower (such as the opening changer 12) to reciprocate or continuously rotate.

[0049] In some embodiments, electronic components such as limit switches and encoders can be used to achieve automatic control and feedback adjustment. Specifically, when the opening change member 12 rotates to a preset position, the limit switch will be triggered, and the limit switch will send an electrical signal to the driver 13. The driver 13 stops or changes the operating state of the driver 13 according to the received signal. The rotation amount or rotation angle of the opening change member 12 is converted into an electrical signal for output. The driver 13 understands the position state of the opening change member 12 in real time by reading the output signal of the encoder, and adjusts it as needed.

[0050] Specifically, multiple flow holes 111 are arranged around the connecting portion 121, the same connecting portion 121 is connected to multiple shielding portions 122, the multiple shielding portions 122 are arranged corresponding to the multiple flow holes 111, and the multiple shielding portions 122 can adjust the opening sizes of the multiple flow holes 111 at the same time.

[0051] In this embodiment, each connection part 121 is simultaneously connected to a plurality of shielding parts 122, and these shielding parts 122 correspond to the flow holes 111 one by one, and the flow holes 111 are shielded by the movement of the shielding parts 122, so as to adjust the opening size thereof. Since all shielding parts 122 are connected to the same connection part 121, when the driving member 13 drives the connection part 121 to drive the shielding parts 122 to rotate, all shielding parts 122 will move synchronously, so as to achieve synchronous adjustment of the opening sizes of the plurality of flow holes 111.

[0052] Further, the partition body 11 is provided with a through hole 112 for the exhaust pipe 23 to pass through, and the connecting portion 121 is provided around the periphery of the through hole 112. In this embodiment, the partition body 11 is provided with a through hole 112 for the exhaust pipe 23 or other pipes to pass through. The through hole 112 not only provides a passage for the exhaust pipe 23 to pass through, but also serves as a reference point for the connection portion 121 to rotate.

[0053] The connecting portion 121 is arranged around the outer periphery of the perforation 112. When a plurality of perforations 112 are arranged on the partition body 11, a corresponding opening conversion member 12 is arranged around each perforation 112. The driving member 13 can drive these opening conversion members 12 at the same time, or drive one of them separately to meet the fluid control requirements of different areas.

[0054] Specifically, the rotation center of the connection part 121 coincides with the center of the through hole 112. This means that the connection part 121 is arranged around the through hole 112, and the rotation movement of the connection part 121 is performed around the center of the through hole 112. In other words, the connection part 121 is designed to be able to rotate around the center of the through hole 112, and its rotation axis is completely at the same point as the center of the through hole 112. This design ensures that the connection part 121 can remain stable and will not deviate from the center position during rotation, and can accurately cover the flow hole 111 as needed.

[0055] In this embodiment, a plurality of perforations 112 are provided, and a plurality of opening change members 12 are provided corresponding to each perforation 112; a plurality of driving members 13 are provided correspondingly, and each driving member 13 is drivingly connected to the corresponding opening change member 12, or, one driving member 13 is provided, and one driving member 13 is drivingly connected to multiple opening change members 12 at the same time.

[0056] In this embodiment, in the configuration that each perforation 112 is provided with a plurality of opening changers 12, each opening changer 12 is equipped with an independent driving member 13. The advantages of this method are high control accuracy and fast response speed, because each opening changer 12 can be independently adjusted as needed. In order to simplify the system structure and reduce costs, a solution in which a single driving member 13 drives a plurality of opening changers 12 at the same time can also be adopted. Although this method cannot achieve the flexibility of using a plurality of driving members 13 to drive a corresponding opening changer 12 in terms of control, it can significantly reduce the number of driving members 13 and does not need to occupy too much space.

[0057] See also Figure 7 An embodiment of the present invention further provides a liquid dispenser, comprising a liquid dispenser body 21, an air intake pipe 22, an air exhaust pipe 23 and the partition 1 as described above, wherein the air intake pipe 22 and the air exhaust pipe 23 are respectively arranged at two ends of the liquid dispenser body 21, one end of the air exhaust pipe 23 extends into the liquid dispenser body 21, and the partition 1 is arranged in the liquid dispenser body 21.

[0058] The liquid distributor 2 further includes an upper cylinder 24, a filter assembly 25, a lower cylinder 26, a steel pipe 27 and an oil return hole 28, wherein the upper cylinder 24 and the lower cylinder 26 are respectively arranged at the upper end and the lower end of the liquid distributor body 21, the oil return hole 28 is arranged on the lower cylinder 26, the filter assembly 25 is arranged at the upper end of the liquid distributor body 21, and the steel pipe 27 is connected with the exhaust pipe 23. In this embodiment, for the convenience of description, the steel pipe 27 is used as a part of the exhaust pipe 23 extending into the interior of the liquid distributor body 21, and the pipeline passing through the perforation 112 is specifically the steel pipe 27. The gas-liquid mixed refrigerant enters from the suction pipe 22, is filtered by the filter assembly 25, and the gaseous refrigerant in the gas-liquid mixed refrigerant after filtering the impurities passes through the steel pipe 27 and the exhaust pipe 23 in turn, and finally enters the compressor 3 for compression, and the liquid refrigerant and the refrigeration oil with a larger density are stored in the liquid distributor body 21, and the refrigeration oil returns to the main body of the compressor 3 through the oil return hole 28.

[0059] Furthermore, the liquid distributor 2 also includes a sensor module 29 , which is located on the exhaust pipe 23 and is used to monitor the pressure pulsation signal, gas flow rate and liquid refrigerant amount in the liquid distributor body 21 .

[0060] The acoustic cavity modal frequency of the dispenser 2 with the flow holes of different opening sizes is different, for example, it can be 2.105e-005Hz or 2.307e-005Hz. The acoustic cavity modal frequency refers to the frequency at which the sound wave can naturally vibrate and maintain its shape and amplitude in a closed or partially closed acoustic cavity. These frequencies are inherent properties of the acoustic cavity and are related to the shape, size and boundary conditions of the acoustic cavity. Different opening sizes of the flow holes 111 correspond to different frequencies.

[0061] In the liquid distributor 2, the flow hole 111 is a small hole or channel that allows fluid (such as gas or liquid) to pass through. The area of ​​the flow hole 111 directly affects the flow velocity, flow rate and propagation characteristics of the sound wave when the fluid passes through.

[0062] Since the propagation and reflection of sound waves in the acoustic cavity are most affected by the area of ​​the flow hole 111, the change in the area of ​​the flow hole 111 will significantly change the modal frequency of the acoustic cavity. Specifically, the increase or decrease in the area of ​​the flow hole 111 will change the acoustic resonance conditions in the acoustic cavity, thereby causing the modal frequency to rise or fall.

[0063] Since the opening sizes of the flow holes 111 of the partition 1 in each liquid dispenser 2 are different, the corresponding acoustic cavity modal frequencies will also be different. When the area of ​​the flow holes 111 increases, the propagation path and reflection mode of the sound wave in the acoustic cavity may change, resulting in the enhancement or weakening of certain modal frequencies, and may even introduce new modal frequencies. On the contrary, when the area of ​​the flow holes 111 decreases, similar effects are observed, but in the opposite direction. Therefore, in specific applications, the opening size of the flow holes 111 can be adjusted according to actual needs.

[0064] like Figure 8 As shown, it is the silencer curve of the liquid distributor 2 with flow holes of different opening sizes. The liquid distributor 2 is equivalent to an internal tube expansion silencer in terms of structure and has the function of a silencer. This figure is a silencer curve calculated by simulation software. The horizontal axis represents the silencer frequency, and the vertical axis represents the silencer effect. The higher the vertical axis, the better the silencer effect of the corresponding silencer frequency. The silencer curve frequencies of the partition 1 and the liquid distributor 2 with flow holes of different opening sizes are different, and it is necessary to select the flow hole 111 with a suitable opening size under different working conditions and different operating frequencies.

[0065] See also Figure 7 An embodiment of the present invention further provides a compressor, comprising the liquid distributor 2 and a compressor body 31 as described above, wherein the other end of the exhaust pipe 23 is connected to the compressor body 31 .

[0066] In this embodiment, a control module is also provided in the compressor 3, and the control module is driven and connected to the driving component 13 and the sensor module 29, and is used for receiving the pressure pulsation signal, gas flow rate and liquid refrigerant amount collected from the sensor module 29, and performing calculation and analysis to obtain the analysis result; the control module transmits the analysis result to the driving component 13, and the driving component 13 drives the opening conversion component 12 to move according to the analysis result, so as to adjust the opening size of the circulation hole 111, so that the noise and performance of the compressor 3 reach the optimal state.

[0067] It should be noted that the control module can be set in the compressor body 31 or on the air conditioner indoor unit. Of course, the pressure pulsation signal, gas flow rate and liquid refrigerant amount collected by the sensor module 29 can also be directly calculated and analyzed through the driving component 13 to obtain the analysis result and directly drive the opening conversion component 12 to rotate.

[0068] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention.
