DETAILED DESCRIPTION

[0033] The specific embodiments described hereinbelow with reference to the drawings should be considered only as illustrative and not as limiting the present application.

[0034] In the present application, unless otherwise specified, the orientation words contained in the terms such as "upper", "lower", "inner", and "outer" only represent the orientation of the terms in the normal use state or the common name understood by the person skilled in the art, and should not be regarded as a limitation of the terms.

[0035] Reference is made to Figures 1-7As shown, an automatic oiling device for an automobile air conditioner compressor, the automatic oiling device comprising: a movable and self-locking bottom plate 101, an oil tank 103 is fixedly arranged on the bottom plate 101, and an oil inlet 104 for oiling is arranged on the oil tank 103; wherein,

[0036] The oil tank 103 is fixedly arranged with an oiling mechanism 200 for automatically oiling the air conditioner compressor body 100, and the oiling mechanism 200 is in communication with the air conditioner compressor body 100.

[0037] In use, the oil tank 103 is pre-filled with an appropriate amount of lubricating oil through the oil inlet 104, the oiling mechanism 200 is placed in the air conditioner compressor body 100, and the detection mechanism 300 starts to work to detect the remaining oil amount in the air conditioner compressor body 100. The detection mechanism 300 compares the detected oil amount with the preset threshold value, and if the remaining oil amount is lower than the preset threshold value, the detection mechanism 300 will send a signal to drive the oiling mechanism 200 to start working. After receiving the signal, the oiling mechanism 200 starts to extract lubricating oil from the oil tank 103, and the lubricating oil is accurately delivered to the oiling port or oil pool of the air conditioner compressor body 100 through the pipeline or channel of the oiling mechanism 200. During the oiling process, the oiling mechanism 200 can adjust the oiling speed and oiling amount according to the real-time feedback of the detection mechanism 300 to ensure that the oil amount in the compressor reaches the optimal state. The oil amount in the compressor can be monitored in real time, and the oiling can be automatically performed when needed, thereby avoiding the tediousness and errors of manual oiling. By accurately controlling the oiling amount and oiling opportunity, the automatic oiling device can ensure that the oil amount in the compressor always remains in the optimal state, thereby prolonging the service life of the compressor and improving its operating efficiency.

[0038] Referring to Figures 2-3 As shown, the oiling mechanism 200 comprises: an oil pump 201, an oil inlet pipe 202, and an oil outlet pipe 203; wherein,

[0039] The oil tank 103 is fixedly arranged with an oil pump 201, the oil inlet end of the oil pump 201 is in communication with the oil tank 103 through the oil inlet pipe 202, and the oil outlet end of the oil pump 201 is in communication with the air conditioner compressor body 100 through the oil outlet pipe 203, and the detection mechanism 300 for detecting the oil amount of the air conditioner compressor body 100 is fixedly arranged on the oil outlet pipe 203.

[0040] In use, the oil inlet pipe 202 is connected to the oil tank 103, and the oil outlet pipe 203 is connected to the oil filling port of the air conditioner compressor body 100. The oil pump 201 draws oil from the oil tank 103 and delivers the oil to the air conditioner compressor body 100 through the oil inlet pipe 202 and the oil outlet pipe 203. During the oil filling process, the detection mechanism 300 changes with the rise of the oil level, and the sensing element continuously monitors this process. When the oil quantity reaches the preset upper limit, the control system shuts down the oil pump 201 to stop oil filling. Through the cooperation of the oil pump 201 and the detection mechanism 300, the automation of the oil filling process is realized, and the manual intervention is reduced.

[0041] Referring to Figures 3-4 As shown in the figure, the detection mechanism 300 comprises: a fixed box 301, a mounting plate 303, a mounting rod 304 and a floating plate 305; wherein,

[0042] The fixed box 301 is fixedly arranged on the oil outlet pipe 203 near the oil outlet end. The inner side wall of the fixed box 301 is provided with a sliding groove 302. The sliding groove 302 is provided with a mounting plate 303 which can slide up and down along the sliding groove 302. The bottom surface of the mounting plate 303 is fixedly provided with a floating plate 305 which contacts the oil level in the air conditioner compressor body 100 through a mounting rod 304. The mounting plate 303 is provided with a sensing element which is electrically connected to the oil pump 201.

[0043] In the above scheme, the fixed box 301 is placed into the air conditioner compressor body 100 along with the oil outlet pipe 203. When the oil quantity in the air conditioner compressor body 100 is small, the floating plate 305 is lowered to drive the mounting plate 303 to slide in the sliding groove 302, so that the sensing element drives the oil pump 201 to start. The oil enters the air conditioner compressor body 100 to push the floating plate 305 to rise. The sensing element detects and records the position change of the mounting plate 303. When the oil quantity reaches the preset upper limit, the control system shuts down the oil pump 201 to stop oil filling. The floating plate 305 rises and falls with the oil level. Through the cooperation of the mounting plate 303 and the sensing element, the oil quantity in the air conditioner compressor body 100 can be accurately detected. Accurate oil quantity detection makes the oil filling process more accurate, avoiding compressor failure caused by excessive or insufficient oil quantity.

[0044] Referring to Figure 6 As shown in the figure, the sensing element comprises: an upper sensing switch 306, a lower sensing switch 307 and a sensing block 308; wherein,

[0045] The inner top wall of the fixed box 301 is fixedly provided with an upper sensing switch 306, and the inner low wall is fixedly provided with a lower sensing switch 307. The upper and lower surfaces of the mounting plate 303 are respectively fixedly provided with a sensing block 308 which is used in cooperation with the upper and lower sensing switches 306 and 307.

[0046] In the above scheme, when the oil amount in the air conditioner compressor body 100 is less, the floating plate 305 is lowered to drive the mounting plate 303 to slide in the sliding groove 302, so that the induction block 308 touches the lower induction switch 307, the oil pump 201 is started, the oil enters the air conditioner compressor body 100, and the floating plate 305 is pushed up. When the induction block 308 touches the upper induction switch 306, the oil pump 201 is closed and the oiling is stopped. The cooperation of the upper induction switch 306 and the lower induction switch 307 with the induction block 308 realizes accurate control of the oil amount, and avoids compressor failure caused by excessive or insufficient oil amount.

[0047] Referring to Figures 3-4 As shown in the figure, the density of the floating plate 305 is less than the density of the oil in the air conditioner compressor body 100.

[0048] In the above scheme, since the density of the floating plate 305 is less than the density of the oil in the air conditioner compressor body 100, when the oil enters the fixed box 301, the floating plate 305 will rise with the oil surface, and when the oil amount decreases, the oil surface will decrease, and the floating plate 305 will also decrease. Ensure that the floating plate 305 can freely rise and fall with the oil surface, so as to accurately reflect the change of the oil amount.

[0049] Referring to Figures 4-5 As shown in the figure, the two sides of the fixed box 301 away from each other are respectively provided with two sets of limiting components 400 for limiting the position of the mounting plate 303 when not in use.

[0050] In the above scheme, the limiting component 400 is used to limit the position of the mounting plate 303 when not in use, to prevent the mounting plate 303 and the floating plate 305 and other components from moving freely, and to avoid misoperation caused by accidental touch or vibration. When oil amount detection or oiling is needed, the operator manually unlocks the limiting component 400.

[0051] Referring to Figures 5-7 As shown in the figure, the limiting component 400 comprises a sliding rod 401, a spring 402 and a wedge-shaped block 404; wherein,

[0052] The sliding rod 401 is slidably penetrated on the fixed box 301, one end of the sliding rod 401 fixedly provided with a wedge-shaped block 404 for supporting the mounting plate 303, and the other end fixedly provided with a limiting plate 403. A spring 402 is sleeved on the sliding rod 401 outside the fixed box 301, and the two ends of the spring 402 are respectively abutted with the side wall of the fixed box 301 and the side surface of the limiting plate 403.

[0053] In use, the operator manually pulls the limiting plate 403 to overcome the elastic force of the spring 402, causing the sliding rod 401 and the wedge block 404 to slide within the fixed box 301. The wedge block 404 moves away from below the mounting plate 303, releasing the support on the mounting plate 303. As oil enters the fixed box 301, it pushes the floating plate 305 to rise, thereby driving the mounting plate 303 to rise. The mounting plate 303 contacts the inclined surface of the wedge block 404, pushing the wedge block 404 to move outward, so that the inductive block 308 on it touches the upper inductive switch 306, thereby closing the oil pump 201 and stopping oiling.

[0054] Referring to Figures 2-3 As shown, the oil outlet pipe 203 is fixedly provided with a one-way valve 204 to prevent backflow of oil in the air conditioner compressor body 100. The oil pump 201 is fixedly provided with a flow meter 205 for displaying flow.

[0055] In the above scheme, when oiling is needed, the oil pump 201 starts, and the oil enters the oil pump 201 through the oil inlet pipe 202, and after being pressurized, it flows to the air conditioner compressor body 100 through the oil outlet pipe 203. When the oil flows through the oil outlet pipe 203, the one-way valve 204 automatically opens to allow the oil to flow to the compressor body 100. At the same time, the flow meter 205 starts to display the flow output by the oil pump 201 to monitor the oiling process. After the oil pump 201 stops, the one-way valve 204 automatically closes due to the decrease in oil pressure, preventing backflow of oil in the air conditioner compressor body 100.

[0056] Referring to Figures 1-3 As shown, a plurality of groups of self-locking universal wheels 102 are fixedly arranged on the bottom surface of the bottom plate 101.

[0057] In the above scheme, the operator pushes the oiling device to move it to the vicinity of the air conditioner compressor that needs to be oiled by taking advantage of the flexibility of the universal wheels 102. When the oiling device needs to be fixed, the operator starts the self-locking function of the universal wheels 102 to make the oiling device stable and immovable. The design of multiple groups of universal wheels 102 makes the oiling device easy to move and adapt to oiling needs in different positions and environments.

[0058] In summary, the automatic oiling device of the automobile air conditioner compressor provided by the utility model, when in use, is placed near the automobile air conditioner compressor to be oiled, the self-locking universal wheel 102 of the stable and movable bottom plate 101 is locked, the oil tank 103 is added with appropriate lubricating oil through the oil inlet 104, the oil outlet pipe 203 of the oiling mechanism 200 is connected to the oiling port of the air conditioner compressor body 100, the connection is ensured to be tight and leakproof, the floating plate 305 can freely float on the oil surface in the air conditioner compressor body 100, the limiting assembly 400 is ensured to be in the non-limiting state, that is, the wedge-shaped block 404 does not support the mounting plate 303, and the spring 402 is in the natural elongation state, the electrical equipment such as the oil pump 201, the upper inductive switch 306, the lower inductive switch 307 and the flow meter 205 is ensured to be connected normally and in the working state, the oil pump 201 is started, the lubricating oil in the oil tank 103 is sucked into the oil pump 201 through the oil inlet pipe 202 and then flows into the air conditioner compressor body 100 through the oil outlet pipe 203, along with the addition of the oil, the floating plate 305 rises along with the rising of the oil surface and drives the mounting plate 303 to slide in the sliding groove 302, when the floating plate 305 rises to a certain height, the inductive block 308 on the mounting plate 303 touches the upper inductive switch 306, the oil pump 201 stops working, and it is indicated that the oiling has reached the preset upper limit of the oil amount. If the oil amount in the air conditioner compressor body 100 decreases during the oiling process, the floating plate 305 will descend, when the inductive block 308 touches the lower inductive switch 307, the oil pump 201 is restarted, the oiling is continued, until the inductive block 308 touches the upper inductive switch 306 again, the oil outlet pipe 203 is provided with the one-way valve 204, and the oil in the air conditioner compressor body 100 is prevented from flowing back to the oiling device after the oil pump 201 stops working.
