[0022] The following will be combined with the accompanying drawings 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, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present invention.

The orientation or position relationship indicated by the terms "upper", "lower", "left", "right", "top", etc. is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0024] like Figures 1 to 11 As shown, an air intake boosting device comprises: a boosting assembly, wherein the boosting assembly is located in an air intake port 1, and the air intake port 1 is connected to a compression chamber 2; a connecting assembly, wherein the connecting assembly is used to connect the boosting assembly and a driving end, and the driving end drives the boosting assembly to move in the air intake port 1 through the connecting assembly to generate suction force to increase the amount of air entering the compression chamber 2 through the air intake port 1 to achieve boosting.

[0025] By setting up a booster component located in the air intake port 1, the driving end of the compressor itself drives the booster component to move through the connecting component to increase the suction power of the air intake port 1, thereby increasing the suction volume entering the compression chamber 2 through the air intake port 1. By utilizing the mechanical properties of the compressor, the booster component in the air intake port 1 of the equipment is driven, the suction action is boosted, the refrigerant suction volume of the compressor is increased, the compressor cooling capacity is increased, and the compressor performance and reliability are improved.

[0026] In the air intake and boosting device of this embodiment, the driving end includes a movable scroll 3, and the movable scroll 3 moves to drive the boosting component to move in the air intake port 1 through the connecting component to increase the air intake volume.

[0027] Specifically, in a traditional compressor structure, the entry of the refrigerant fluid is achieved through a pressure difference or a given initial speed during intake. However, in an embodiment of the present invention, a connecting component is set to match the initial speed of the compressor movement with the boosting component to drive the intake and boosting component, thereby adding a suction force to the intake port 1 between the intake port 1 and the compression chamber 8, and an air delivery force to the compression chamber 2 to achieve the purpose of intake boosting.

[0028] In the air intake and boosting device of this embodiment, the air intake port 1 is opened on the fixed scroll 4, the boosting assembly is rotatably connected to the fixed scroll 4, and the movable scroll 3 is inserted into the fixed scroll 4 to form a compression chamber 2.

[0029] By setting the boosting assembly and the static scroll 4 to be rotatably connected, the static scroll 4 provides support for the boosting assembly and limits it, the movable scroll 3 and the static scroll 4 move relative to each other to generate suction to suck the refrigerant into the compression chamber 2 through the suction port 1, and at the same time, the movable scroll 3 drives the boosting assembly to rotate in the suction port 1 opened on the static scroll 4 during the movement, thereby increasing the suction force on the refrigerant in the suction port 1 to achieve the purpose of increasing the suction volume.

[0030] In the air intake boosting device of this embodiment, the boosting assembly includes a fan blade 5, and the movable scroll 3 rotates in the fixed scroll 4 and drives the fan blade 5 to rotate in the air intake port 1 through the connecting assembly to generate suction force to increase the air intake volume.

[0031] Specifically, the fan blade 5 is connected to the movable scroll 2 through a connecting component. When the movable scroll 3 rotates in the fixed scroll 4, the fan blade 5 is driven to rotate in the air intake port 1 opened on the fixed scroll 4 through the connecting component. Then, the suction force generated by the rotation of the fan blade 5 cooperates with the rotation of the movable scroll 3 to increase the air intake amount of the air intake port 1 into the compression chamber 2, thereby increasing the cooling capacity of the compressor and achieving the purpose of improving the performance of the compressor.

[0032] In the air intake boosting device of this embodiment, the outer diameter of the fan blade 5 is not greater than the diameter of the air intake port 1, and the fan blade 5 is spirally arranged so as to rotate to generate suction force to increase the amount of air intake entering the compression chamber 2 through the air intake port 1 to achieve boosting.

[0033] Specifically, the air intake port 1 is a hole opened on the fixed scroll disk 4, and is connected to the compression chamber 2 between the movable scroll disk 3 and the fixed scroll disk 4. The fan blade 5 is located in the above-mentioned hole. By setting the outer diameter of the fan blade 5 structure to be less than or equal to the diameter of the air intake port 1, it is ensured that the fan blade 5 can rotate in the air intake port 1 without interference with the wall of the air intake port 1, so that the fan blade 5 can rotate stably and achieve pressurization.

[0034] The fan blade 5 is set to be a spiral blade with a certain spiral angle. When the device is running and rotating, it will not only generate suction to pressurize the suction process, but also because the spiral surface is set with an inclination, the refrigerant sucked into the suction port 1 can be guided into the compression chamber 2 through the inclination, which plays a guiding role, increases the suction volume of the suction port 1, and further improves the suction efficiency of the suction port 1.

[0035] In the air intake boosting device of this embodiment, the boosting assembly further comprises a rotating shaft 6 for supporting the fan blades 5, the rotating shaft 6 is rotationally connected to the fixed scroll 4, and the end of the rotating shaft 6 is fixedly connected to the connecting assembly.

[0036] Specifically, the rotating shaft 6 is located on the axis of the air intake port 1, and the rotating shaft 6 is driven to rotate in the air intake port 1 through the connecting component, thereby driving the fan blade 5 to rotate. Through the above-mentioned configuration, the rotating shaft 6 provides support for the fan blade 5. At the same time, the fan blade 5 is equidistant from the wall of the air intake port 1 during rotation, and the rotation is more stable. The size of the fan blade 5 can also be matched with the diameter of the air intake port 1 as much as possible to increase the outer diameter of the fan blade 5 and improve the boost efficiency.

[0037] In the air intake and boosting device of this embodiment, a support block 7 for mounting a boosting assembly is provided at the bottom of the fixed scroll plate 4 . The boosting assembly penetrates the support block 7 and is fixedly connected to a connecting assembly located below the support block 7 .

[0038] By setting up the support block 7 to provide support for the rotating shaft 6 and the fan blade 5, it is convenient for the connecting component to be connected to the rotating shaft 6 from the bottom of the support block 7, and then it is easy to connect the connecting component to the movable scroll 3 inserted in the fixed scroll 4, thereby realizing indirect connection and transmission between the movable scroll 3 and the rotating shaft 6.

[0039] Specifically, a mounting hole for installing the rotating shaft 6 is opened on the support block 7. When installing the fan blade 5, the rotating shaft 6 is placed in the air intake hole 1, passes through the mounting hole at the support block 7 at the bottom of the fixed scroll plate 4, and is combined with the movable scroll plate 3 through a connecting assembly.

[0040] Preferably, the mounting hole is opened at the center (center of the circle) of the air intake port 1, so that the fan blade 5 can rotate in the air intake port 1 without interference with the wall of the air intake port 1, thereby improving the rotation stability of the fan blade 5, thereby increasing the suction force on the refrigerant and increasing the intake volume.

[0041] In the air intake boosting device of this embodiment, the connecting assembly includes a connecting rod 8, a first end of the connecting rod 8 is fixedly connected to the boosting assembly, and a second end of the connecting rod 8 is rotationally connected to the movable scroll 3. When the movable scroll 3 rotates, it drives the connecting rod 8 to rotate around the first end to realize the rotation of the boosting assembly.

[0042] Specifically, the connecting rod 8 is fixedly connected to the bottom end of the rotating shaft 6, and the connecting rod 8 is provided to connect the rotating shaft 6 and the movable scroll 3. The connecting rod 8 is driven by the movable scroll 3 to move, rotates around the first end connected to the rotating shaft 6, and then drives the rotating shaft 6 to rotate in the mounting hole, thereby realizing the rotation and pressurization of the fan blade 5 in the air intake port 1.

[0043] By adopting the above arrangement, the mechanical properties of the suction action of the movable scroll 3 are utilized to drive the booster component in the suction port 1 of the pump body, and then the suction action is pressurized by the movement of the booster component, thereby increasing the refrigerant suction amount of the compressor, increasing the cooling capacity of the compressor, and achieving the purpose of improving the performance of the compressor and improving the reliability of the compressor.

[0044] Preferably, the rotating shaft 6 and the connecting rod 8 are connected in a snap-fit ​​manner to facilitate the disassembly and assembly of the fan blades 5. A plug-in hole is provided at the corresponding end of the connecting rod 8. Snap-in blocks protruding from the rod body of the rotating shaft 6 are provided on both sides of the bottom end of the rotating shaft 6. A snap-in groove matching the snap-in block is provided in the plug-in hole. The snap-in block is plugged into the snap-in groove to limit the circumferential direction of the rotating shaft 6 to avoid relative rotation between the rotating shaft 6 and the connecting rod 8, thereby ensuring that when the connecting rod 8 is driven by the passive scroll disk 3 to move, the connecting rod 8 drives the rotating shaft 6 to rotate smoothly in the mounting hole on the support block 7.

[0045] In the air intake and boosting device of this embodiment, the connecting assembly also includes a connecting pin 9, which is fixedly connected to the movable scroll plate 3. A transfer hole 10 is provided at the second end of the connecting rod 8. The connecting rod 8 is sleeved on the periphery of the connecting pin 9 through the transfer hole 10 and is rotatably connected to the connecting pin 9.

[0046] By setting the connecting pin 9 to cooperate with the transfer hole 10, when the movable scroll 3 rotates in the fixed scroll 4, the connecting pin 9 is driven to rotate synchronously, and the connecting pin 9 is rotationally connected with the transfer hole 10, thereby driving the connecting rod 8 to rotate around the rotating shaft 6. At the same time, the rotating shaft 6 rotates by itself, so as to realize the rotation of the fan blade 5 in the air intake port 1 to achieve the purpose of increasing the intake volume and achieving a pressurization effect.

[0047] Specifically, when the movable scroll 3 moves, the center point Q of the movable scroll 3 makes an eccentric circular motion around the center point P of the fixed scroll 4; the connecting pin 9 is located on the base plate of the movable scroll 3. When the movable scroll 3 moves, the connecting pin 9 cooperates with the adapter hole 10 on the connecting rod 8, so that the axis point M of the connecting pin 9 on the base plate of the movable scroll 3 will make a circular motion around the axis point N of the rotating shaft 6. Since the connecting part at point N is connected by a clamping block, point M makes a circular motion, which drives point N, i.e., the rotating shaft 6, to rotate, thereby driving the fan blade 5 to operate, thereby achieving the effect of suction and pressurization from the suction port 1 to the compression chamber 2.

[0048] It can be expected that the distance between points Q and P is equal to the distance between points M and N.

[0049] In the air intake and boosting device of this embodiment, a avoidance groove 11 is provided at the bottom of the support block 7, and the avoidance groove 11 is used to accommodate the connecting rod 8 so that the movable scroll 3 drives the connecting rod 8 to rotate around the first end and then drives the boosting assembly to rotate.

[0050] Specifically, an avoidance groove 11 is provided to avoid the connecting rod 8 located above the movable scroll 3, so that the movable scroll 3 and the fixed scroll 4 fit tightly together to ensure the sealing of the compression chamber 2. At the same time, the above-mentioned arrangement reduces the length of the rotating shaft 6, so that the rotation of the rotating shaft 6 in the mounting hole is more stable.

[0051] Preferably, the groove surface of the avoidance groove 11 is in an arc shape that matches the rotation trajectory of the connecting rod 8. The avoidance groove 11 is arranged as described above to guide the connecting rod 8. At the same time, the above structure makes the overall structure of the device more compact, further improves the rotation stability of the connecting rod 8 and the rotating shaft 6, and enables the fan blade 5 to effectively rotate to achieve pressurization, thereby improving the intake and pressurization efficiency.

[0052] It can be imagined that the rotating shaft 6 and the connecting pin 9 are respectively inserted into the connecting rod 8 from the upper and lower sides, the connecting rod 8 is in contact with the surface of the movable scroll 3, and the bottom end of the rotating shaft 6 does not protrude from the bottom surface of the connecting rod 8. The above structure avoids affecting the smooth rotation of the connecting rod 8 on the surface of the movable scroll 3.

[0053] In the air intake boosting device of this embodiment, the fixed scroll 4 is fixed above the upper bracket 12, and the movable scroll 3 is rotatably connected in the mounting groove at the top of the upper bracket 12. The movable scroll 3 performs eccentric circular motion in the upper bracket 12 and drives the boosting component to rotate in the air intake port 1 through the connecting component to achieve boosting.

[0054] Specifically, a channel for installing a drive shaft is opened in the middle of the upper bracket 12. The drive shaft drives the movable scroll 3 to perform eccentric circular motion relative to the stationary scroll 4 in the upper bracket 12, thereby realizing the suction action and driving the boost component to rotate to increase the suction power in the suction port 1 and increase the suction volume.

[0055] In the air intake and boosting device of this embodiment, an air intake pipe assembly 13 is fixedly connected to the air intake port 1. The air intake pipe assembly 13 is located above the fixed scroll plate 4. An air outlet 14 connected to the compression chamber 2 is provided on the top of the fixed scroll plate 4.

[0056] An air intake pipe assembly 13 is provided to connect the refrigerant. The air intake pipe assembly 13 is sealed and plugged into the top of the air intake port 1. The plugging end thereof is located above the fan blade 5 and is spaced apart from the fan blade 5 to avoid affecting the smooth rotation of the fan blade 5 and ensure the pressurization effect.

[0057] On the other hand, the present application also proposes an air conditioner, including an air intake boost device described in any of the above embodiments. It can be expected that the air conditioner in the present application includes all the beneficial effects of the air intake boost device in the above embodiments, which will not be repeated here.

For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0059] Although the embodiments of the present invention have been shown and described in detail, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
