However, the current adjustment effect of oil supply is relatively poor. Summary of the Invention

[0003] This invention provides an oil supply regulating device and a compressor to solve the problem of poor oil supply regulation effect in current applications.

[0004] To solve the above-mentioned technical problems, the present invention is implemented as follows:

[0005] In a first aspect, embodiments of the present invention provide an oil supply regulating device for a compressor, comprising: a first component, a second component, and a connecting member, wherein the first component and the second component are sleeved together, at least one of the first component and the second component is provided with an oil passage, and the connecting member is respectively connected to the first component and the second component;

[0006] The connecting member drives the first component and the second component to move relative to or away from each other, so that the oil circuit switches between a first state and a second state. In the first state, the oil circuit is connected to the oil supply channel of the compressor so that the amount of oil passing through the oil circuit is a first quantity.

[0010] Optionally, the oil circuit includes a first oil circuit and a second oil circuit, wherein the first oil circuit is formed on the first component and the second oil circuit is formed on the second component.

[0011] Optionally, there may be multiple oil passages, and the multiple oil passages may be located on the second component.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] See Figure 1 and Figure 2 , Figure 1 This is a front view of a compressor provided in an embodiment of the present invention. Figure 2 This is a top view of a compressor provided in an embodiment of the present invention. Figure 3 It is along Figure 2 A schematic diagram of the structure obtained by cross-sectioning the AA plane. Figure 4 yes Figure 3 Enlarged view of the structure of region B in the middle.

[0029] See Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the structure of an oil supply regulating device 100 for a compressor provided in an embodiment of the present invention. Figure 6 This is an exploded view of an oil supply regulating device 100 for a compressor provided in an embodiment of the present invention, as shown below. Figure 5 and Figure 6 As shown, the oil supply regulating device 100 of the compressor includes: a first component 10, a second component 20 and a connecting member 30. The first component 10 and the second component 20 are sleeved together. At least one of the first component 10 and the second component 20 is provided with an oil passage 40. The connecting member 30 is connected to the first component 10 and the second component 20 respectively.

[0030] The connector 30 drives the first component 10 and the second component 20 to move relative to or away from each other, so that the oil passage 40 switches between a first state and a second state. In the first state, the oil passage 40 is connected to the oil supply channel of the compressor so that the amount of oil passing through the oil passage 40 is a first quantity. In the second state, the oil passage 40 is at least partially closed so that the amount of oil passing through the oil passage 40 is a second quantity. The first quantity is greater than the second quantity.

[0031] The working principle of this invention can be found in the following description:

[0032] Since the first component 10 and the second component 20 are sleeved together, and the connecting piece 30 is connected to the first component 10 and the second component 20 respectively, the first component 10 and the second component 20 can be driven to move relative to each other or in opposite directions through the connecting piece 30. This allows the oil circuit 40 to be adjusted to different states such as the first state or the second state, thereby adjusting the amount of oil in the oil supply regulating device 100 of the compressor. This makes the adjustment of the amount of oil more convenient and enhances the effect of adjusting the amount of oil.

[0033] The compressor's oil supply regulating device 100 can be set between the compressor's oil supply channel and the component to be supplied with oil. That is, the oil in the oil supply pipeline needs to enter the component to be supplied with oil through the oil passage 40 in the compressor's oil supply regulating device 100. In this way, the oil quantity can be regulated by controlling the state of the oil passage 40.

[0034] It should be noted that the above-mentioned adjustment method for the state of oil circuit 40 is not limited. For example, as an optional adjustment method, when oil circuit 40 is in the first state, oil circuit 40 is 100% open; when oil circuit 40 is in the second state, the opening degree of oil circuit 40 can be 50%. Alternatively, as another optional adjustment method, there can be multiple oil circuits 40. When oil circuit 40 is in the first state, all multiple oil circuits 40 can be open; when oil circuit 40 is in the second state, at least some of the multiple oil circuits 40 are open, and the other part of oil circuits 40 are closed. In this way, the oil quantity can be adjusted through the above methods.

[0035] It should be noted that, in order to adjust the state of the oil passage 40, as an optional implementation, a blocking member for closing or opening the oil passage 40 may be provided on at least one of the first component 10 and the second component 20. When the oil passage 40 is in the first state, the blocking member is separated from the oil passage 40; when the oil passage 40 is in the second state, the blocking member blocks at least a portion of the oil passage 40 to achieve the closure of at least a portion of the oil passage 40.

[0036] The specific materials used to manufacture the aforementioned shielding components are not limited here. For example, the aforementioned shielding components can be made of waterproof and oil-proof materials.

[0037] As another alternative implementation, since the first component 10 and the second component 20 are sleeved together, the first component 10 is used to close at least a portion of the oil passage 40 on the second component 20, or the second component 20 is used to close at least a portion of the oil passage 40 on the first component 10.

[0038] In this way, at least part of the oil passage 40 can be closed without the need for a separate shielding component, so that the oil passage 40 is in the second state. At the same time, since the first component 10 and the second component 20 can move relative to each other under the drive of the connecting member 30, the oil passage 40 can be in the first open state by changing the relative position of the first component 10 and the second component 20, thus realizing the switching of the oil passage 40 between the first state and the second state.

[0039] It should be noted that the specific type and location of the connector 30 are not limited here. For example, as an optional implementation, the connector 30 can be a driving member, and the output shaft of the driving member can be connected to the first component 10 and the second component 20 respectively. In this way, the driving member can drive the first component 10 and the second component 20 to move relative to each other.

[0040] Alternatively, as another optional implementation, see [link to relevant documentation]. Figure 6The connecting member 30 can also be an elastic member, so that the driving member can switch between a compressed state and a stretched state. Driven by the restoring deformation force of the elastic member, the first component 10 and the second component 20 can move relative to each other.

[0041] It should be noted that the connector 30 can be disposed inside the first component 10 and the second component 20, or it can be disposed outside the first component 10 and the second component 20.

[0042] As an optional implementation method, see [link to implementation details]. Figure 5 The first component 10 includes a first cavity 11, and the second component 20 includes a second cavity 21. The first cavity 11 and the second cavity 21 are connected. The connector 30 is located inside the first cavity 11 and the second cavity 21. One end of the connector 30 is fixedly connected to the first inner wall of the first cavity 11, and the other end of the connector 30 is fixedly connected to the second inner wall of the second cavity 21.

[0043] The volume of the accommodating cavity formed by the connection of the first cavity 11 and the second cavity 21 can change with the position of the first component 10 and the second component 20. For example, when the connector 30 is an elastic element, when the first component 10 and the second component 20 move relative to each other, the volume of the accommodating cavity formed by the connection of the first cavity 11 and the second cavity 21 can decrease, and correspondingly, the connector 30 can also be in a compressed state at this time; when the first component 10 and the second component 20 move in opposite directions, the volume of the accommodating cavity formed by the connection of the first cavity 11 and the second cavity 21 can increase, and correspondingly, the connector 30 can be in a stretched state at this time.

[0044] When the oil passage 40 switches from the first state to the second state, the connector 30 can provide a force to the first component 10 and the second component 20 to drive the first component 10 and the second component 20 to move relative to each other, so that the first component 10 or the second component 20 closes at least a portion of the oil passage 40, so that the oil passage 40 is in the second state; when the oil passage 40 switches from the second state to the first state, the connector 30 can provide a force to the first component 10 and the second component 20 to drive the first component 10 and the second component 20 to move in opposite directions, so that the first component 10 or the second component 20 opens the oil passage 40, so that the oil passage 40 is in the first state.

[0045] In this embodiment of the invention, since the connecting member 30 is located in the first cavity 11 and the second cavity 21, the volume of the entire oil supply regulating device 100 of the compressor can be reduced. At the same time, the connecting member 30 can also be protected. In addition, since the first component 10 has the first cavity 11 and the second component 20 has the second cavity 21, the mass of the entire oil supply regulating device 100 of the compressor can be reduced.

[0046] It should be noted that the first inner wall and the second inner wall can be inner walls that are arranged opposite to each other, so that when the connecting member 30 drives the first component 10 and the second component 20 to move relative to or away from each other, it can move along the direction of the line connecting the first inner wall and the second inner wall, thereby reducing the friction when the first component 10 and the second component 20 move relative to or away from each other and enhancing the driving effect.

[0047] It should be noted that the term "first component 10 and second component 20 are fitted together" can mean that the first component 10 is fitted inside the second component 20, or that the second component 20 is fitted inside the first component 10. The specific meaning is not limited here.

[0048] As an optional implementation method, see [link to implementation details]. Figure 5 and Figure 6 The first component 10 is inserted inside the second component 20, and the first component 10 can move relative to or away from the second component 20 under the drive of the connecting member 30. Thus, since the first component 10 is fitted inside the second component 20, it can be understood that the width of the first component 10 is smaller than the width of the second component 20. This means that the smaller-width first component 10 can be controlled to move relative to or away from the wider second component 20, thereby reducing the power consumption and resistance of the drive, making it more convenient for the first component 10 to move relative to or away from the second component 20.

[0049] As an optional implementation method, see [link to implementation details]. Figure 5 and Figure 6 The oil passage 40 includes a first oil passage 41 and a second oil passage 42. The first oil passage 41 is formed on the first component 10. (See also...) Figures 5 to 8 The second oil passage 42 is located on the second component 20.

[0050] The specific location of the first oil passage 41 on the first component 10 is not limited here, and the location of the second oil passage 42 on the second component 20 is not limited here.

[0051] For example, the first oil passage 41 can be opened on the side wall of the first component 10, and the side wall can be an inner wall adjacent to the first inner wall. The second oil passage 42 can be opened on the second inner wall of the second component 20. In this way, the oil in the oil supply channel can conveniently enter the component to be supplied with oil by passing through the first oil passage 41 and the second oil passage 42 in sequence.

[0052] In this embodiment of the invention, since the first oil passage 41 is opened on the first component 10 and the second oil passage 42 is opened on the second component 20, the oil in the oil supply channel can enter the component to be supplied with oil in sequence through the first oil passage 41 and the second oil passage 42. That is, the path between the first oil passage 41 and the second oil passage 42 can form the oil supply pipeline inside the compressor's oil supply regulating device 100, thereby extending the length of the oil supply pipeline inside the compressor's oil supply regulating device 100, and making it more convenient to adjust the oil quantity.

[0053] As an optional implementation, there are multiple oil passages 40, and these multiple oil passages 40 are formed on the second component 20. In this way, only multiple oil passages 40 need to be formed on the second component 20, thereby reducing the processing difficulty and cost of the oil passages 40 and improving processing efficiency.

[0054] The multiple oil passages 40 can be distributed on different surfaces of the second component 20. For example, the multiple oil passages 40 can be distributed on the second inner wall and the side wall, where the side wall refers to the side wall of the second component 20 adjacent to the second inner wall. In this way, oil in the oil supply channel can flow from a portion of the multiple oil passages 40 into the second cavity 21 and the first cavity 11, and then flow out through another portion of the multiple oil passages 40 to the component to be supplied with oil.

[0055] It should be noted that, as another optional implementation method, the difference from the above implementation method is that multiple oil passages 40 can be opened on the first component 10, thus increasing the diversity and flexibility of the opening position of the oil passages 40.

[0056] Optionally, the orifice diameters of the plurality of oil passages 40 are different. The different orifice diameters of the oil passages 40 result in different adjustments to the oil volume when different oil passages 40 are closed. When the orifice diameter of an oil passage 40 is larger and the oil passage 40 is closed, the oil volume decreases more significantly. When the orifice diameter of an oil passage 40 is smaller and the oil passage 40 is closed, the oil volume decreases less significantly. This makes the adjustment of the oil volume more flexible.

[0057] It should be noted that the distribution of oil passages 40 with different orifice diameters is not limited here. For example, the orifice diameter of the oil passage 40 can gradually increase or decrease along the direction from the first component 10 to the second component 20. For another example, the orifice diameter of the oil passage 40 located in the middle position is the largest, and then the orifice diameter of the oil passage 40 gradually decreases from the middle position to the two ends. For another example, the orifice diameter of the oil passage 40 located in the middle position is the smallest, and then the orifice diameter of the oil passage 40 gradually increases from the middle position to the two ends.

[0058] As an optional implementation, a first limiting member 12 is provided on one of the first component 10 and the second component 20, and a second limiting member 22 is provided on the other of the first component 10 and the second component 20, and the first limiting member 12 and the second limiting member 22 are used in conjunction.

[0059] Among them, see Figures 6 to 8 The first component 10 is provided with a first limiting member 12, and the second component 20 is provided with a second limiting member 22. The types of the first limiting member 12 and the second limiting member 22 are not limited here. For example, if one of the first limiting member 12 and the second limiting member 22 is a limiting protrusion, the other can be a limiting groove. See [reference needed]. Figure 6 The first limiting member 12 can be understood as a limiting groove, while the second limiting member 22 can be understood as a limiting protrusion protruding towards the limiting groove.

[0060] In this way, with the cooperation of the first limiting member 12 and the second limiting member 22, the phenomenon of relative rotation of the first component 10 and the second component 20 when they move relative to or away from each other can be reduced, making the direction of relative or away movement between the first component 10 and the second component 20 more accurate.

[0061] In order to better cooperate in use, the dimensions between the first limiting member 12 and the second limiting member 22 can be adapted.

[0062] See Figure 4 This invention also provides a compressor, including an oil supply channel 200, a component to be supplied with oil 300, and an oil supply regulating device 100 for the compressor. Oil in the oil supply channel 200 enters the component to be supplied with oil 300 through the oil passage 40 in the oil supply regulating device 100. Since the compressor in this embodiment includes the oil supply regulating device 100, it has the same beneficial technical effects as the oil supply regulating device 100 in the above embodiments. The specific structure of the oil supply regulating device 100 can be found in the corresponding descriptions in the above embodiments.

[0063] It should be noted that the type of the oil supply component 300 in this embodiment is not limited. For example, the oil supply component 300 can be a rotating scroll plate or a fixed scroll plate, and the oil supply component 300 can also be called a compression mechanism.

[0064] As an optional implementation, see [link to implementation details]. Figure 4 The compressor includes a crankshaft 201, and the oil supply channel 200 and the oil supply regulating device 100 of the compressor are both disposed inside the crankshaft 201. Under the action of the centrifugal force of the crankshaft 201, the connecting part 30 of the oil supply regulating device 100 of the compressor drives the first component 10 and the second component 20 to move relative to each other.

[0065] The second component 20 of the compressor's oil supply regulating device 100 can be fixed inside the crankshaft 201, while the first component 10 can move relative to or away from the second component 20. That is, the first component 10 can be referred to as the movable part, while the second component 20 can be referred to as the fixed part.

[0066] In this embodiment of the invention, since the crankshaft 201 generates centrifugal force when it rotates, the centrifugal force can provide the connecting member 30 with the power to drive the first component 10 and the second component 20 to move relative to or away from each other. Therefore, there is no need to set up a separate power source to provide power to the connecting member 30, which further simplifies the compressor mechanism, reduces the size of the compressor, and reduces the cost of use.

[0067] It should be noted that, Figure 4 The arrow C in the diagram can be used to indicate the direction of oil flow within the compressor, while Figures 5 to 8 The structure shown can be understood as Figure 4 Enlarged structural view of the oil supply regulating device 100 of the medium compressor.

[0068] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
