Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" means two or more.

[0027] like Figures 1 to 4 As shown, the utility model provides an ultrasonic compressor. The ultrasonic compressor includes: an ultrasonic power source 1, a movable part 2, a fixed part 3, a first one-way valve 4 and a second one-way valve 5. The output end of the ultrasonic power source 1 generates a mechanical wave that vibrates along a first direction X. The movable part 2 is connected to the output end of the ultrasonic power source 1, and the movable part 2 is driven to reciprocate along the first direction X by the output end of the ultrasonic power source 1. The fixed part 3 is a pipe with an open end. The movable part 2 is arranged in the fixed part 3. The movable part 2 has a tendency to reciprocate in the fixed part 3 along the first direction X, and the movable part 2 is sealed against the inner wall of the fixed part 3. The outlet of the first one-way valve 4 is connected to the interior of the cavity 6 formed by the fixed part 3 and the movable part 2. The first one-way valve 4 is configured to allow the refrigerant to enter the cavity 6 formed by the fixed part 3 and the movable part 2, and to prevent the refrigerant from being discharged from the first one-way valve 4. The inlet of the second one-way valve 5 is connected to the interior of the cavity 6 formed by the fixed part 3 and the movable part 2. The second one-way valve 5 is configured to discharge the refrigerant from the interior of the cavity 6 formed by the fixed part 3 and the movable part 2, and prevent the refrigerant from entering the interior of the cavity 6 from the second one-way valve 5.

[0028] In some examples, the ultrasonic power source 1 of the ultrasonic compressor may include a transducer and an ultrasonic horn. For example, the transducer is relatively fixed to the fixing member 3, and the output end of the transducer is fixedly connected to the ultrasonic horn via a connecting member. The ultrasonic horn extends in a first direction X, and the ultrasonic horn outputs longitudinal vibration. The amplitude of the longitudinal vibration output by the ultrasonic horn can be 0.05 mm to 1 mm, and the frequency of the longitudinal vibration output by the ultrasonic horn can be 18 to 25 kHz. To improve the structural stability of the ultrasonic horn, the ultrasonic horn can be made of titanium alloy.

[0029] The output end of the ultrasonic horn is fixedly connected to the movable part 2. Under the drive of the ultrasonic horn, the movable part 2 can achieve a higher frequency and vibrate back and forth along the first direction X. It can be understood that based on the fact that the movable part 2 is driven by the ultrasonic horn at a frequency of 18~25KHz and an amplitude of 0.05mm~1mm, it vibrates at a high frequency along the first direction X.

[0030] During the reciprocating motion of the movable member 2, the volume of the cavity 6 formed by the fixed member 3 and the movable member 2 increases as the movable member 2 moves away from the fixed member 3. Under the premise that the tension of the refrigerant and the pressure inside the cavity 6 decrease, the refrigerant is introduced into the cavity 6 through the first one-way valve 4. When the movable member 2 moves toward the fixed member 3, the volume of the cavity 6 formed by the fixed member 3 and the movable member 2 decreases. Only the opening pressure of the second one-way valve 5 needs to be controlled. That is, when the pressure inside the cavity 6 exceeds the set value, the second one-way valve 5 is opened, thereby achieving the compression of the refrigerant using ultrasound.

[0031] In some embodiments, a plurality of raised strips 7 are provided on the end surface of the movable member 2 facing the fixed member 3. A plurality of grooves are provided on the inner wall of the fixed member 3, where the movable member 2 and the movable member 3 move relative to each other, and the orthographic projection of each raised strip 7 on the inner wall of the fixed member 3 along the first direction X is located in a corresponding groove.

[0032] In some examples, the fixed part 3 can be a circular tube with an open end, and the movable part 2 can be a circular plate. In order to improve efficiency, the movable part 2 can minimize thickness and use a material with lower density while ensuring sufficient strength, so as to facilitate the operation driven by the ultrasonic horn and improve the energy efficiency ratio.

[0033] It can be understood that in order to improve the ability of the movable part 2 to squeeze the refrigerant when it moves toward the fixed part 3 and the tension on the refrigerant when the movable part 2 moves away from the fixed part 3, a plurality of raised strips 7 are provided on the end face of the movable part 2 facing the fixed part 3. In this example, the plurality of raised strips 7 can be annular protrusions with a cross-section that is a triangle with the corners pointing to the bottom surface of the fixed part 3.

[0034] A corresponding groove is also provided on the bottom surface of the fixing part 3, that is, when the movable part 2 moves toward the fixing part 3, the raised strip 7 can be correspondingly provided in the groove, which can avoid the edges of the raised strip 7 from having a strong collision with the fixing part 3. In addition, the groove on the bottom surface of the fixing part 3 also has a strong tension effect on the refrigerant.

[0035] In some embodiments, a first inlet is provided on the fixed part 3, one end of the first inlet is connected to the first one-way valve 4, and when the volume of the cavity 6 formed by the fixed part 3 and the movable part 2 is the smallest, the other end of the first inlet is only connected to the cavity 6.

[0036] The fixed part 3 is provided with a second inlet, one end of which is communicated with the second one-way valve 5, and when the volume of the cavity 6 formed by the fixed part 3 and the movable part 2 is the smallest, the other end of the second inlet is only communicated with the cavity 6.

[0037] For example, the fixed member 3 is a circular tube, and the first and second inlets are both located on the sidewall or bottom surface of the fixed member 3 away from the movable member 2. When the space of the cavity 6 changes, the first and second inlets are always connected to the interior of the cavity 6, preventing the refrigerant from entering the outside of the cavity 6.

[0038] In some embodiments, a plurality of annular partitions are provided on the inner wall of the fixed member 3 along the first direction X. The movable member 2 includes a main shaft and a plurality of movable pressure plates fixed to the main shaft. A movable pressure plate is provided between two adjacent annular partitions and between an annular partition and the bottom plate at the other end of the fixed member 3. The main shaft is parallel to the first direction X, and a seal is provided between the main shaft and the annular partitions.

[0039] A first inlet and a second inlet are provided between the two annular partitions. When the volume of the first space between the annular partition and the movable pressure plate is minimum, the other end of the first inlet and the other end of the second inlet are only connected to the corresponding first space.

[0040] A first inlet and a second inlet are provided between the annular partition and the bottom plate at the other end of the fixing member 3. When the volume of the second space between the annular partition and the bottom plate at the other end of the fixing member 3 is minimum, the other end of the first inlet and the other end of the second inlet are only connected to the corresponding second space.

[0041] In some examples, the fixing member 3 may be a cylindrical tube with an open end. A plurality of annular baffles are disposed within the fixing member 3. The annular baffles are annular in structure, and the outer rings of the annular baffles are fixedly connected to the inner wall of the fixing member 3. A side surface is formed between the inner and outer rings of the annular baffles. A cross section passing through the centerline of the fixing member 3 intersects both the side surface and the inner wall of the fixing member 3. The angle between a first line segment where the cross section passing through the centerline of the fixing member 3 intersects the side surface and the second line segment where the cross section passing through the centerline of the fixing member 3 intersects the inner wall of the fixing member 3 is greater than 90°, and may be, for example, 120° to 150°.

[0042] A plurality of raised strips 7 may be provided on the side surface. At the same time, a groove is provided on the corresponding surface of each movable pressure plate of the movable part 2. The specific functions are described above and will not be elaborated here.

[0043] The main shaft of the movable part 2 passes through the inner rings of multiple annular partitions, the outer edge of the movable pressure plate is sealed with the inner wall of the fixed part 3, and the main shaft and the inner ring of the annular partition are sealed. In this way, adjacent annular partitions form a cavity 6 between adjacent movable pressure plates. When the movable pressure plate vibrates at a high frequency, the refrigerant is rapidly compressed under the action of the first one-way valve 4 and the second one-way valve 5.

[0044] In some embodiments, the first one-way valve 4 and the second one-way valve 5 are both Tesla valves, wherein the second one-way valve 5 can control the internal pipe diameter according to the pressure value of the refrigerant to achieve the refrigerant pressure in the cavity 6 reaching the set value.

[0045] In some embodiments, the ultrasonic compressor also includes a shell 8, and the ultrasonic power source 1, movable part 2, fixed part 3, first one-way valve 4 and second one-way valve 5 are all arranged in the shell 8. The power cord of the ultrasonic power source 1 passes through the wall of the shell 8 and extends to the outside of the shell 8. The pipeline communicating with the first one-way valve 4 and the second one-way valve 5 passes through the inner wall of the shell 8 and extends to the outside of the shell 8. The shell 8 is sealed.

[0046] The housing 8 can prevent refrigerant leakage and further improve the sealing performance.
