DETAILED DESCRIPTION

[0025] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, a detailed description of the preferred embodiments of the present utility model will be given.

[0026] Reference Figures 1a to 2 The figure shows an embodiment of the automatic oil filling device and air conditioner production equipment of the present invention. The automatic oil filling device includes an oil reservoir 1 and an oil delivery assembly 2. The oil reservoir 1 stores lubricating oil. The oil delivery assembly 2 includes an oil pipe 21, a drive member 22, and a quick connector 23. The drive member 22 is fixed between the two ends of the oil pipe 21. One end of the oil pipe 21 is connected to the oil reservoir 1, and the other end is connected to the quick connector 23. One end of the quick connector 23 is connected to the heat exchanger pipe. When the drive member 22 is activated, the lubricating oil flows from the oil reservoir 1 through the oil pipe 21 to the quick connector 23 and enters the interior of the heat exchanger pipe.

[0027] Specifically, the automatic oil filling device is used to automatically fill the heat exchanger pipe fittings with oil, so that the inside of the heat exchanger pipe fittings is lubricated, and the internal thread teeth of the heat exchanger pipe fittings are prevented from falling over when the heat exchanger pipe is expanded, wherein the heat exchanger pipe fittings refer to the main channels for heat exchange inside the heat exchanger, and the heat exchanger pipe fittings include but are not limited to aluminum pipes; the automatic oil filling device includes an oil storage part 1 and an oil delivery component 2, the oil storage part 1 serves as a storage container for lubricating oil to ensure sufficient lubricating oil supply, the lubricating oil is stored inside the oil storage part 1, and the lubricating oil is used to lubricate the heat exchanger pipe fittings; the oil delivery component 2 is used to deliver the lubricating oil to the inside of the heat exchanger pipe fittings, and the oil delivery component 2 includes an oil pipe 21, a quick connector 23 and a driving member 22, the oil pipe 21 is a delivery pipe for the lubricating oil; the quick connector 23 is used to fixedly connect the heat exchanger pipe; the driving member 22 provides power for the delivery of the lubricating oil, so that the lubricating oil can flow from the oil storage member 1 along the oil pipe 21 to the heat exchanger pipe; the driving member 22 is fixed on the oil pipe 21 and is located between the two ends of the oil pipe 21, and is used to pump the lubricating oil from the oil storage member 1 into the oil pipe 21, and make the lubricating oil flow from one end of the oil pipe 21 to the other end of the oil pipe 21; one end of the oil pipe 21 is connected to the oil storage member 1, the other end of the oil pipe 21 is connected to the quick connector 23, and one end of the quick connector 23 is connected to the heat exchanger pipe.

[0028] When the automatic oil filling device is started, the driving member 22 is started to draw lubricating oil from the oil storage member 1 into the oil pipe 21. The lubricating oil flows along the oil pipe 21 toward the quick connector 23 and flows into the interior of the heat exchanger pipe through the quick connector 23 to achieve lubrication of the heat exchanger pipe.

[0029] The present application sets up an automatic oil filling device to automatically fill the heat exchanger pipe fittings with oil, and forms a lubricating oil transmission channel with the oil pipe 21 and the quick connector 23. The lubricating oil is extracted by the driving member 22 and flows from the oil storage member 1 through the oil pipe 21 and the quick connector 23 to reach the inside of the heat exchanger pipe fittings, thereby lubricating the heat exchanger pipe fittings, realizing automatic, accurate and efficient injection of lubricating oil, providing a strong guarantee for the stable operation of mechanical equipment, and when the heat exchanger pipe is expanded, the internal thread teeth of the heat exchanger pipe fittings are prevented from falling over, thereby ensuring the heat exchange effect of the heat exchanger.

[0030] More specifically, the oil pipe 21 is a high-pressure oil pipe 21, which has high pressure bearing capacity, good pulse performance, bending resistance, fatigue resistance, oil resistance, heat resistance, and aging resistance. In addition, the oil pipe 21 is made of flexible material, thereby ensuring convenient and safe operation during the oil filling process.

[0031] More specifically, the lubricating oil stored in the oil storage member 1 is volatile oil used for processing heat exchanger pipe fittings of the heat exchanger in the production area, so that the automatic oiling device does not need to use special dedicated oil, and local materials are used, which is low-cost and does not require mixing of multiple oils. There will be no reaction between different oils, thereby avoiding the appearance of black precipitates on the heat exchanger pipe fittings that affect the subsequent welding quality of the heat exchanger pipe fittings.

[0032] In one embodiment, referring to Figures 1a to 1g As shown, the oil delivery component 2 also includes a diverter 24, and the oil pipe 21 includes a main oil pipe 211 and multiple branch oil pipes 212. The two ends of the main oil pipe 211 are respectively connected to the oil storage component 1 and the diverter 24, and one end of the multiple branch oil pipes 212 is connected to the diverter 24, and the other end is connected to the quick connector 23. Specifically, the oil pipe 21 includes a main oil pipe 211 and multiple branch oil pipes 212. The main oil pipe 211 is the main channel for lubricating oil transmission. The branch oil pipes 212 are used to guide the diverted lubricating oil to the quick connector 23 until it flows to the heat exchanger pipe. Each end of the branch oil pipe 212 is correspondingly provided with a quick connector 23, and each quick connector 23 is correspondingly connected to one of the heat exchanger pipes. Therefore, in this embodiment, the lubricating oil is guided from the oil storage part 1 to multiple branch oil pipes 212 through one main oil pipe 211, and flows to multiple heat exchanger pipes respectively, thereby improving the oil injection efficiency.

[0033] The main oil pipe 211 and the multiple branch oil pipes 212 are connected by the flow divider 24. The main function of the flow divider 24 is to evenly and accurately distribute the lubricating oil from the main oil pipe 211 to each branch oil pipe 212, ensuring that each heat exchanger pipe component receives the appropriate amount of lubricating oil. The flow divider 24 is typically designed as a compact valve body structure, internally containing multiple oil outlets and a precise flow control mechanism. These oil outlets correspond one-to-one with the branch oil pipes 212. By adjusting the flow control mechanism, the lubricating oil flow rate of each branch oil pipe 212 can be precisely set.

[0034] Therefore, when the automatic oil filling device is started, the lubricating oil flows from the oil storage part 1 to the main oil pipe 211, flows along the main oil pipe 211 to the diverter 24, and flows to the multiple branch oil pipes 212 through the diverter 24, and finally flows to the multiple heat exchanger pipes through the multiple quick connectors 23, thereby realizing a one-inlet and multiple-outlet oil filling method to improve the oil filling efficiency, and the flow rate and flow of the lubricating oil to the multiple branch oil pipes 212 are controlled by the diverter 24 to improve the accuracy of oil filling.

[0035] More specifically, the driving member 22 is fixed in the main oil pipe 211 , and the driving member 22 and the diverter pipe are spaced apart to improve the structural stability of the oil delivery assembly 2 and allow the lubricating oil to flow smoothly to the diverter 24 .

[0036] In a specific embodiment, referring to Figures 1a to 1g As shown, the oil delivery component 2 also includes a blowing device 25, which is connected to the main oil pipe 211 and is used to blow air toward the heat exchanger pipes. Specifically, the oil delivery component 2 also includes a blowing device 25, which is used to blow air into the main oil pipe 211 so that the air flow flows toward the heat exchanger pipes. The blowing device 25 is connected to the main oil pipe 211; therefore, when the automatic oil filling device completes oil filling, the blowing device 25 is activated, and the blowing device 25 blows air toward the inside of the main oil pipe 211. The air flow flows along the main oil pipe 211 toward the diverter 24 and the multiple branch oil pipes 212, and finally flows to the heat exchanger pipes through the quick connector 23, so as to blow the lubricating oil toward the heat exchanger pipes, thereby preventing the lubricating oil from flowing back, improving the oil filling accuracy of the automatic oil filling device, and improving the structural stability of the automatic oil filling device.

[0037] At the same time, this embodiment adopts a one-inlet-multiple-outlet method to simultaneously blow multiple heat exchanger pipes, ensuring uniform lubrication inside the heat exchanger pipes and high blowing efficiency.

[0038] In one embodiment, referring to Figures 1a to 1gAs shown, the blowing device 25 includes a blowing piece 251, an air pipe 252 and a one-way valve 253. The two ends of the air pipe 252 are respectively connected to the blowing piece 251 and one end of the one-way valve 253, and the other end of the one-way valve 253 is connected to the main oil pipe 211. Specifically, the blowing device 25 is used to blow air into the interior of the main oil pipe 211 in the direction of the heat exchanger pipe. After the oil filling is completed, the medium-pressure air can be directly connected to purge the heat exchanger pipe, which has a more uniform lubrication effect and avoids a large amount of volatile oil from accumulating in the pipe; the blowing device 25 includes a blowing piece 251, an air pipe 252 and a one-way valve 253. The blowing piece 251 is a gas generation or supply source. The blowing piece 251 can be a compressed air tank, an air pump or other air source equipment, which is responsible for providing gas with sufficient pressure and flow to flow in the direction of the air pipe 252; one end of the air pipe 252 is connected to the blowing piece 251, and the other end is connected to the one-way valve 253, and one end of the one-way valve 253 is also connected to the main oil pipe 211. The air pipe 252 is used to transmit the airflow generated by the blowing piece 251 to the main oil pipe 211, and the one-way valve 253 is used to limit the flow direction of the airflow and lubricating oil. When the blowing device 25 is started, the gas generated by the blowing member 251 is transported to the one-way valve 253 through the air pipe 252. Under the action of the one-way valve 253, the gas is allowed to flow into the main oil pipe 211 in one direction; when the blowing operation is completed, the one-way valve 253 automatically closes to prevent gas backflow and leakage.

[0039] In this embodiment, the one-way valve 253 controls the flow of gas and lubricating oil, preventing lubricating oil from flowing from the main oil pipe 211 to the air pipe 252, thereby affecting the operation of the blowing member 251. Simultaneously, the one-way valve 253 ensures that gas can flow in only one direction, that is, gas can only flow from the blowing member 251 through the air pipe 252 to the main oil pipe 211, preventing gas backflow. This helps prevent contamination of the lubricating oil in the main oil pipe 211 and maintains the pressure and stability of the oil delivery assembly 2. Through the rational design and installation of the blowing member 251, air pipe 252, and one-way valve 253, one-way, efficient gas transmission can be ensured within the automatic oil filling device, while improving the reliability and safety of the device.

[0040] In a specific embodiment, referring to Figures 1a to 1gAs shown, the oil delivery component 2 also includes a pressure gauge 26, which is connected to the branch oil pipe 212 and is used to monitor the oil injection pressure. Specifically, the oil delivery component 2 also includes a pressure gauge 26, which is connected to the branch oil pipe 212. The pressure gauge 26 is used to display and monitor the pressure changes during the oil injection process in real time, ensuring that the lubricating oil can be delivered to each branch oil pipe 212 according to the predetermined pressure and flow rate. Among them, each branch oil pipe 212 is correspondingly provided with a pressure gauge 26, and the pressure gauge 26 is located between the two ends of the branch oil pipe 212 and on the side of the branch oil pipe 212 close to the quick connector 23. By monitoring the reading of the pressure gauge 26, the operator can promptly discover and adjust abnormal conditions during the oil injection process, such as excessively high or low pressure, thereby avoiding problems such as equipment damage or poor lubrication. At the same time, the pressure gauge 26 can effectively monitor the oil injection pressure and ensure the effective oil injection volume.

[0041] In one embodiment, referring to Figures 1a to 1g As shown, the oil delivery assembly 2 also includes a control cabinet 27, which is electrically connected to the driver 22 and is used to control the oil injection time. Specifically, the oil delivery assembly 2 also includes a control cabinet 27, which is electrically connected to the driver 22, thereby controlling the oil injection time of the automatic oil injection device by controlling the start and stop of the driver 22. The control cabinet 27 is one of the core components of the automatic oil injection device. Through the electrical connection with the driver 22 (such as the motor, pump, etc.), the control cabinet 27 achieves precise control of the oil injection process. More specifically, the control cabinet 27 can set and adjust key parameters such as oil injection time, oil injection pressure, and oil injection frequency, thereby ensuring that the lubricating oil is delivered to each heat exchanger pipe according to predetermined requirements and time intervals. During the oil injection process, the control cabinet 27 can automatically start and stop the driver 22 according to the set oil injection time and other parameters, thereby controlling the delivery of lubricating oil. At the same time, the control cabinet 27 can also monitor the pressure, flow and other parameters during the oil filling process in real time and adjust them as needed. In addition, the control cabinet 27 can also record historical data during the oil filling process to provide data support for equipment maintenance and optimization.

[0042] In this embodiment, by properly designing and installing the control cabinet 27, precise control of the automatic oil injection device can be achieved, thereby improving the reliability and service life of the equipment.

[0043] More specifically, the control cabinet 27 is started using a conventional 22V voltage to improve the safety of the automatic oil filling device and reduce energy consumption.

[0044] In this embodiment, the control cabinet 27 automatically controls the oil filling time of the entire process of the automatic oil filling device, and the pressure gauge 26 monitors the oil filling process, thereby realizing automatic oil filling and improving oil filling efficiency.

[0045] In a specific embodiment, referring to Figure 2 As shown, the quick connector 23 is provided with a self-locking portion 231 , and the self-locking portion 231 is located at the end of the quick connector 23 and is used to fix the heat exchanger pipe. Specifically, the quick connector 23 is a device that can achieve quick connection of pipelines without the use of tools, and can be connected and disconnected with the pipeline through simple operations such as rotation or pushing and pulling; one end of the quick connector 23 is connected to the branch oil pipe 212, and the upper and lower ends of the quick connector 23 can be connected to two of the heat exchanger pipe fittings respectively. Generally, one end of the quick connector 23 is connected to one of the heat exchanger pipe fittings, and the other end is spare; self-locking parts 231 are provided at the upper and lower ends of the quick connector 23, and the self-locking parts 231 are used to fix the heat exchanger pipe fittings to prevent the heat exchanger pipe fittings from accidentally falling off; the design of the self-locking parts 231 enables the quick connector 23 to maintain a stable connection state after being connected to the heat exchanger pipe fitting, and even if it is subjected to external force impact or vibration, the heat exchanger pipe fitting can remain connected without loosening, thereby improving the fixity of the connection between the quick connector 23 and the heat exchanger pipe fitting.

[0046] When using the quick connector 23 with the self-locking part 231 to connect the heat exchanger pipe, the operator only needs to insert the heat exchanger pipe into the corresponding port of the quick connector 23, and then press the heat exchanger pipe onto the self-locking part 231 to achieve the connection. During the connection process, the locking mechanism of the self-locking part 231 will automatically lock the heat exchanger pipe to ensure its stable connection. If disconnection is required, it is only necessary to operate the unlocking mechanism.

[0047] In this embodiment, the use of the quick connector 23 greatly improves the efficiency and convenience of connecting the heat exchanger pipe and the oil branch pipe 212. In particular, when the quick connector 23 is designed with the self-locking portion 231, this convenience and safety are further improved.

[0048] In one embodiment, referring to Figures 1a to 1gAs shown, the automatic oil filling device also includes a movable oil delivery base 3, and the oil delivery base 3 is used to fix and move the oil delivery component 2. Specifically, the oil delivery component 2 is arranged adjacent to the oil storage part 1, so as to facilitate the delivery of lubricating oil from the oil storage part 1 to the oil delivery component 2, and finally to the heat exchanger pipe; the automatic oil filling device also includes an oil delivery base 3, and the oil delivery base 3 can be freely moved. Since the oil delivery component 2 includes multiple structural parts, the oil delivery component 2 is fixed on the oil delivery base 3 to integrate the oil delivery component 2. When the automatic oil filling device needs to be moved, the oil delivery component 2 can be moved by moving the oil delivery base 3, so that the oil delivery component 2 can be moved anytime and anywhere. The flexibility and convenience of the automatic oil filling device are improved so that the automatic oil filling device can flexibly adapt to different working environments and layout requirements. For example, when the production line or equipment layout changes, the oil transfer base 3 can be easily moved to adjust the position of the oil transfer component 2; when performing equipment maintenance or cleaning, the oil transfer base 3 can also be moved to a position that is convenient for operation. In addition, the movable oil transfer base 3 also facilitates the transportation and installation of the equipment, reduces the difficulty and cost of operation, thereby improving the adaptability and practicality of the equipment; at the same time, it also facilitates the installation, commissioning and maintenance of the automatic oil filling device.

[0049] More specifically, a plurality of rollers are provided along the bottom end of the oil delivery base 3 , and the plurality of rollers are spaced apart along the circumference of the oil delivery base 3 , thereby facilitating the movement of the oil delivery base 3 .

[0050] In a specific embodiment, referring to Figures 1a to 1gAs shown, the automatic oil filling device further includes a movable oil storage base 4 , which is fixed at the bottom end of the oil storage member 1 and is used to move the oil storage member 1 . Specifically, the automatic oil filling device also includes an oil storage base 4, which can be moved freely. Since the oil storage part 1 needs to store lubricating oil, the oil storage part 1 has a certain weight. In order to facilitate the transportation of the oil storage part 1, the oil storage part 1 is fixed on the oil storage base 4. When the oil storage part 1 needs to be moved, the oil storage part 1 can be moved by moving the oil storage base 4, so that the oil storage part 1 can be moved anytime and anywhere to improve the flexibility and convenience of the automatic oil filling device; at the same time, in the automatic oil filling device, the use of the oil storage base 4 enables the automatic oil filling device to flexibly adapt to different working environments and layout requirements. For example, when the production line or equipment layout changes, the oil storage base 4 can be easily moved to adjust the position of the oil storage part 1; when performing equipment maintenance or cleaning, the oil storage base 4 can also be moved to a position that is convenient for operation; in addition, the oil storage base 4 also facilitates the supply and management of oil, reduces the difficulty and cost of operation, and brings greater convenience and benefits to the production and management of the enterprise.

[0051] More specifically, a plurality of rollers are provided along the bottom end of the oil storage base 4, and the plurality of rollers are spaced apart along the circumference of the oil storage base 4, thereby facilitating the movement of the oil storage base 4;

[0052] At the same time, the oil storage base 4 and the oil delivery base 3 are arranged at intervals, and the oil storage component 1 and the oil delivery component 2 are respectively fixed on the oil storage base 4 and the oil delivery base 3, so that the automatic oil filling device has a frame structure, which can be installed and disassembled as a whole, is convenient and fast, has strong versatility, and can be moved independently.

[0053] This embodiment also provides an air conditioner production equipment (not shown in the figure), which includes an automatic oil filling device. The automatic oil filling device can adopt any automatic oil filling device provided by the present utility model. Since the previous description has already made a detailed introduction to the specific structure and working principle of the automatic oil filling device, for the sake of conciseness of the description, it will not be repeated here.

[0054] For example, when assembling the automatic oil filling device, first insert the oil inlet pipe 21 into the oil storage part 1, then insert the main oil pipe 211 into the oil storage part 1, and connect each branch oil pipe 212 to each heat exchanger pipe fitting; when using the automatic oil filling device, start the control cabinet 27 switch, and set the fixed oil filling time by program, the driving part 22 extracts lubricating oil from the oil storage part 1 and injects it into the heat exchanger pipe fitting, and the oil filling time is controlled by the time relay of the control cabinet 27 for a single oil filling time, and the oil filling is stopped after the countdown ends; after the oil filling is completed, the heat exchanger pipe fitting is pressure maintained, that is, the tail of the heat exchanger pipe fitting is blocked with a rubber cap to maintain the pressure; after the pressure holding is completed, the air pipe 252 is connected to the blowing part 251 to purge the inside of the heat exchanger pipe fitting to ensure that the lubrication of the heat exchanger pipe fitting is uniform and effective, and to ensure that a large amount of excess lubricating oil is docked in the heat exchanger pipe fitting.

[0055] The air conditioner production equipment in this embodiment adopts the automatic oil injection device provided by the utility model.
