[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0028] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0029] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0030] See also Figures 1 to 7 As shown, according to an embodiment of the present invention, a cylinder is provided, comprising a cylinder body 1 and an enthalpy increasing pin 2, wherein the cylinder body 1 has a compression chamber 3, and a mounting channel 4 and an air supplement hole 5 are respectively configured on the cylinder body 1, wherein one end of the mounting channel 4 leads to the compression chamber 3, and the other end of the mounting channel 4 leads to the outside of the cylinder body 1, and one end of the air supplement hole 5 leads to the compression chamber 3, and the air supplement hole 5 also leads to the mounting channel 4, and the enthalpy increasing pin 2 is arranged in the mounting channel 4. The enthalpy increasing pin 2 has a cut-off position and a conducting position in the mounting channel 4, and when the enthalpy increasing pin 2 is in the cut-off position, the air supplement hole 5 is not connected with a partial section of the mounting channel 4 on the side of the enthalpy increasing pin 2 facing away from the compression chamber 3; when the enthalpy increasing pin 2 is in the conducting position, the air supplement hole 5 is connected with a partial section of the mounting channel 4 on the side of the enthalpy increasing pin 2 facing away from the compression chamber 3. The two ends of the enthalpy increasing pin 2 face the compression chamber 3 and the outside of the cylinder body 1 respectively. The enthalpy increasing pin 2 can automatically switch between the conducting position and the cutoff position under the action of the pressure difference at its two ends.

[0031] In this technical solution, when the cylinder of the present application is applied to the rotor compressor of the air conditioner, the high-pressure pipeline in the air conditioner is connected to the installation channel 4 of the cylinder body 1, and the compressor is operated under the extreme conditions of low-temperature heating or high-temperature refrigeration, if the pressure of the refrigerant in the high-pressure pipeline is greater than the refrigerant pressure in the compression chamber 3 of the cylinder body 1, then the enthalpy increase pin 2 is in the conducting position under the action of the pressure difference, and the refrigerant in the high-pressure pipeline will flow into the air-filling hole 5 through the installation channel 4, and then enter the compression chamber 3 through the air-filling hole 5, and finally increase the amount of refrigerant in the compression chamber 3, so that the exhaust volume of the compressor is increased, thereby realizing the efficient enthalpy increase and stable operation of the compressor under the extreme conditions of low-temperature heating or high-temperature refrigeration, thereby improving the heating or cooling efficiency of the air conditioner. It can be understood that when the compressor is operated under normal conditions, if the pressure of the refrigerant in the high-pressure pipeline is less than the refrigerant pressure in the compression chamber 3 of the cylinder body 1, then the enthalpy increase pin 2 is in the cut-off position under the action of the pressure difference, and the high-pressure pipeline will not replenish the refrigerant into the compression chamber 3 of the cylinder body 1.

[0032] See also Figures 2 to 4 As shown, the air-increasing hole 5 is connected to the mounting channel 4 in a partial section, the enthalpy-increasing pin 2 is slidably arranged in the mounting channel 4, and a first stop and a second stop are formed in the mounting channel 4; when the enthalpy-increasing pin 2 is limited to the first stop, the enthalpy-increasing pin 2 is in the cut-off position, and when the enthalpy-increasing pin 2 is limited to the second stop, the enthalpy-increasing pin 2 is in the conducting position; in the process that the enthalpy-increasing pin 2 automatically slides from the first stop to the second stop under the action of the pressure difference, the connecting area between the air-increasing hole 5 and the partial section mounting channel 4 on the side of the enthalpy-increasing pin 2 facing away from the compression chamber 3 gradually increases.

[0033] In this embodiment, when the air-injection hole 5 is partially connected to the installation channel 4, it indicates that the length of the connection between the air-injection hole 5 and the installation channel 4 is relatively long. Then, the pressure difference between the refrigerant in the external high-pressure pipeline and the refrigerant in the compression chamber 3 can be used to act on the enthalpy-increasing pin 2, so that the enthalpy-increasing pin 2 can automatically adjust the displacement according to the pressure difference, and then automatically adjust the amount of refrigerant added to the compression chamber 3 according to the size of the opening of the longer connection. Specifically, when the pressure of the refrigerant in the external high-pressure pipeline is much higher than the pressure of the refrigerant in the compression chamber 3, the enthalpy-increasing pin 2 slides farther to the side where the compression chamber 3 is located under the action of the large pressure difference, and the connecting area between the air-injection hole 5 and the partial section of the installation channel 4 on the side of the enthalpy-increasing pin 2 facing away from the compression chamber 3 is larger, and more refrigerant is added to the compression chamber 3. When the pressure of the refrigerant in the external high-pressure pipeline is relatively small compared to the pressure of the refrigerant in the compression chamber 3, the distance that the enthalpy-increasing pin 2 slides to the side where the compression chamber 3 is located is closer under the action of a small pressure difference, and the communication area between the air-increasing hole 5 and the partial segment installation channel 4 on the side of the enthalpy-increasing pin 2 facing away from the compression chamber 3 is smaller, and the refrigerant added to the compression chamber 3 is less, thereby realizing automatic adjustment of the amount of refrigerant added according to the pressure difference. It can be understood that when the enthalpy-increasing pin 2 slides to the second stop, the communication area between the air-increasing hole 5 and the partial segment installation channel 4 on the side of the enthalpy-increasing pin 2 facing away from the compression chamber 3 is the largest, and the air-increasing amount in this state is the largest. When the pressure of the refrigerant in the external high-pressure pipeline is less than the pressure of the refrigerant in the compression chamber 3, the enthalpy-increasing pin 2 will slide to the side away from the compression chamber 3, and finally slide to the first stop to cut off the communication between the air-increasing hole 5 and the partial segment installation channel 4 on the side of the enthalpy-increasing pin 2 facing away from the compression chamber 3.

[0034] See also Figure 1 As shown, the installation channel 4 includes a first channel section 41 and a second channel section 42, one end of the second channel section 42 leads to the compression chamber 3, the other end of the second channel section 42 leads to the first channel section 41, and the cross-sectional area of ​​the second channel section 42 is smaller than the cross-sectional area of ​​the first channel section 41, and the junction between the second channel section 42 and the first channel section 41 forms a second stop, the enthalpy increasing pin 2 is slidably arranged in the first channel section 41, the cross-sectional area of ​​the enthalpy increasing pin 2 is larger than the cross-sectional area of ​​the second channel section 42, and the air supplement hole 5 has a partial section connected to the first channel section 41.

[0035] In this technical solution, when the installation channel 4 includes a first channel section 41 and a second channel section 42 of different sizes, the second stop can be naturally formed at the junction of the second channel section 42 and the first channel section 41. For the formation of the first stop, an external high-pressure pipe can be inserted into the first channel section 41, so that the end of the external high-pressure pipe becomes the first stop in the first channel section 41, and then the enthalpy-increasing pin 2 automatically slides back and forth between the first stop and the second stop under the action of the pressure difference. Among them, the enthalpy-increasing pin 2 is adapted to the first channel section 41, ensuring that the enthalpy-increasing pin 2 can be placed in the first channel section 41, and the enthalpy-increasing pin 2 can also cut off the connection between the first channel section 41 and the air supply hole 5 when air supply is not needed. The enthalpy-increasing pin 2 can be a cylinder, the air supply hole 5 can be a circular hole, and the installation channel 4 can be a circular channel.

[0036] See also Figures 2 to 4 As shown, there are multiple air supply holes 5 , one end of each air supply hole 5 leads to the compression chamber 3 , and each air supply hole 5 also leads to the installation channel 4 .

[0037] In this embodiment, when there are multiple air supply holes 5 , the external high-pressure pipeline can simultaneously supply air to the compression chamber 3 through the multiple air supply holes 5 , thereby improving the air supply efficiency.

[0038] See also Figures 2 to 4 As shown, the air supply holes 5 surround the installation channel 4 and are spaced apart from each other.

[0039] In this technical solution, since the high-pressure refrigerant sent into the installation channel 4 by the external high-pressure pipeline diffuses outward evenly along the circumference of the installation channel 4 during diffusion, when each air supply hole 5 surrounds the installation channel 4 respectively, the high-pressure refrigerant in the installation channel 4 can enter each air supply hole 5 more smoothly, thereby reducing the flow resistance during air supply and further improving the air supply efficiency.

[0040] See also Figure 4 As shown, a slide vane groove 6 and an exhaust port 7 are constructed on the cylinder body 1 , and the exhaust port 7 , the mounting channel 4 and the air supply hole 5 are all located on the same side of the slide vane groove 6 .

[0041] In this embodiment, the exhaust port 7 on the cylinder body 1 is used to discharge the refrigerant compressed in the compression chamber 3. When the exhaust port 7, the mounting channel 4 and the air supply hole 5 are all on the same side of the vane groove 6, the high-pressure refrigerant added into the compression chamber 3 can be quickly discharged from the exhaust port 7, thereby improving the exhaust efficiency.

[0042] See also Figure 4 As shown, the air supply hole 5 is adjacent to the exhaust port 7, so that the refrigerant supplied into the compression chamber 3 can be discharged more quickly from the exhaust port 7, thereby further improving the exhaust efficiency.

[0043] As a specific implementation, multiple installation channels 4 and multiple air supply holes 5 can also be constructed on the cylinder body 1, one end of each installation channel 4 leads to the compression chamber 3, the other end of each installation channel 4 leads to the outside of the cylinder body 1, one end of each air supply hole 5 leads to the compression chamber 3, and each air supply hole 5 also leads to each installation channel 4, and the number of enthalpy increasing pins 2 is multiple, and each enthalpy increasing pin 2 is slidably arranged in each installation channel 4. This is equivalent to arranging multiple air supply structures in parallel on a cylinder, and the multiple air supply structures are arranged at different angles on the exhaust side of the cylinder. When multiple air supply structures simultaneously replenish air into the compression chamber 3, the air supply amount can be increased.

[0044] The present invention also provides a compressor, which is a rotary compressor. The compressor includes the aforementioned cylinder, crankshaft, roller and vane, the roller is mounted on the crankshaft, and performs eccentric motion in the compression chamber 3 of the cylinder as the shaft rotates, thereby achieving gas compression. The vane is arranged in the vane groove 6 in the cylinder, and is used to separate the compression chamber 3. It should be noted that the air replenishment scheme of the present application can be applied not only to single-cylinder compressors, but also to multi-cylinder compressors.

[0045] The present invention also provides an air conditioner, comprising the aforementioned compressor.

[0046] It is easy for those skilled in the art to understand that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention. The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention, and these improvements and variations should also be regarded as the protection scope of the present invention.
