Description

Technical Field

[0001] This application relates to the field of lubrication device technology, specifically an automatic oiler. Background Technology

[0002] An automatic lubricator, also known as a lubrication pump, can deliver lubricating oil in a timed and metered manner to the parts of the equipment that require lubrication. This avoids the time-consuming and labor-intensive process of manually adding lubricant to each piece of equipment in the production workshop.

[0003] However, when an automatic grease dispenser is first installed, or when the grease supply in the tank is depleted and the system is restarted after refilling, the grease supply interval must be manually set at least once. For example, the electric automatic grease dispenser described in patent application number 201220279601.7 has multiple toggle switches as control input elements connected to the circuit board. However, these physical buttons have a certain gap between them and the housing of the electric automatic grease dispenser. When workers press these switches, their hands may be covered in oil and grease, which can seep into the housing through the gap, causing short circuits. Furthermore, when manually pressing the switches, oil can adhere to the indicator panel next to the switches, obscuring the indicators and instructions and affecting readability. Additionally, workers sometimes operate the system wearing gloves, which reduces the effective triggering rate of the switches when pressing them with bare hands. Utility Model Content

[0037] Please refer to Figure 1 - Figure 12 This embodiment provides an automatic oiler, including:

[0038] Sensor 1, wherein sensor 1 is detachably connected to the automatic oiler;

[0039] The base 2 has an internal mounting area 210 and an external operation panel area 220.

[0040] Pump 3, which is installed in the installation area 210;

[0041] The control board 4 is electrically connected to a first sensor 5, which is disposed corresponding to the operation panel area 220; the pump 3 is electrically connected to the control board 4; the first sensor 5 is used to collect information on the duration of the sensing element 1 being close to the first sensor 5.

[0042] The control board 4 can be set to the installation area 210.

[0043] Indicator light 6 is located in the operation panel area 220; indicator light 6 is electrically connected to the control board 4; indicator light 6 performs any one of the following actions according to the control signal from the control board 4: constant light, off light, flashing light, or color change.

[0044] Indicator light 6, first sensor 5, and touch switch 7 can be mounted on control board 4.

[0045] Working principle: The base 2 is used to connect with the lubricant container 9. When the base 2 is connected to a new lubricant container 9, or when the oil supply parameters need to be changed, the user takes out the sensor 1 and brings it close to the location of the first sensor 5 in the operation panel area 220. After the first sensor 5 senses that the sensor 1 is close, it sends a corresponding sensing signal to the control board 4. The control board 4 is equipped with a processor and a storage element; the storage element stores executable program files.

[0046] If set so that after the first sensor 5 senses the proximity of the sensing element 1 for 10 seconds, the control board 4 controls the indicator light 6 to flash red 10 times, and then activates the device to enter the parameter adjustment state.

[0047] Next, the user takes out the sensor 1 and brings it close to the first sensor 5 of the operation panel area 220. After a certain period of time, until the indicator light 6 flashes red five times, the sensor 1 is removed from the first sensor 5 of the operation panel area 220. After 1 to 2 seconds, the sensor 1 is brought close to the first sensor 5 of the operation panel area 220 again. There are multiple indicator lights 6. The operation panel area 220 has month information, such as March, June, September, and December, on the side of the multiple indicator lights 6. The multiple indicator lights 6 light up and turn off in a cyclical pattern. When the indicator light 6 corresponding to the desired month lights up, the sensor 1 is removed, and the month setting is completed.

[0048] If the pumping volume of pump 3 is set, it can be switched according to the corresponding indicator light 6, using the same sensing element 1 as the first sensor 5.

[0049] Then, when the set monthly interval arrives, the control board 4 will automatically control the pump 3 to supply lubricating grease to the parts of the device that need lubrication.

[0050] In some embodiments, the indicator light 6 is orange, indicating that the automatic oiler is activated; the indicator light 6 is red, indicating that the automatic oiler is not activated.

[0051] After the operator has completed the setup, the sensor 1 can be reinstalled in its designated position on the automatic lubricator, such as on the base 2. This avoids the problems caused by traditional operation methods and manual pressing of switches. The automatic lubricator's settings and parameters can be controlled non-contactly via the sensor 1 and the control panel 220, improving the lubricator's cleanliness and enhancing the user experience.

[0052] Please refer to Figure 6 , Figure 9 and Figure 10 It includes a touch switch 7 and a covering layer 8. The number of touch switches 7 is one or more and they are located in the operation panel area 220. The touch switches 7 are electrically connected to the control board 4. The covering layer 8 covers the touch switches 7 and the indicator lights 6. The covering layer 8 has a light-transmitting part 810 corresponding to the indicator lights 6.

[0053] The covering layer 8 is a plastic film, and the covering layer 8 is detachably glued to the operation panel area 220.

[0054] The touch switch 7 can also be directly pressed by the operator, allowing users who have not yet learned the aforementioned improved operation to perform traditional setting operations, thus avoiding delays in the work process. The method by which the touch switch 7 is pressed to set the parameter state can be the same as the process of the sensor 1.

[0055] In addition, the automatic oiler is already activated. When the user removes the sensor 1 and brings it close to the location of the first sensor 5 in the operation panel area 220, the control board 4 will control the indicator light 6 to flash red 10 times before the device turns off. Alternatively, the user can press and hold the touch switch 7 until the indicator light 6 flashes red 10 times before the device turns off.

[0056] By selecting a plastic film as the covering layer 8, it is detachably glued to the operation panel area 220, facilitating user replacement after the covering layer 8 gets dirty using traditional methods. Furthermore, the covering layer 8 covers the touch switch 7 and the indicator light 6; the covering layer 8 has a light-transmitting portion 810 corresponding to the indicator light 6, preventing oil from the operator's hands from entering the mounting area 210 through the gaps between the indicator light 6 and the base 2 housing, and between the touch switch 7 and the base 2 housing, without obstructing the light of the indicator light 6.

[0057] In some embodiments, the covering layer 8 includes a substrate layer and an instruction information carrier layer connected to the substrate layer.

[0058] The substrate layer plays a primary role, while the information carrier layer can be a layer containing text, directional patterns, or other information, and can be printed with ink.

[0059] For example, the indicator pattern could be a teardrop shape with the words "Forced Lubrication" below it, covered by a touch switch 7. Generally, after changing the lubricant container 9, the touch switch 7 is pressed repeatedly to force lubrication several times until the air is expelled and the automatic lubricator dispenses oil normally without air bubbles.

[0060] In some embodiments, the first sensor 5 is a Hall sensor, and the sensing element 1 is connected to a magnet 110.

[0061] The first sensor 5 can also be other types of sensors, such as a light sensor. In this case, the magnet 110 and the sensing element 1 are not required. The operator can simply place his hand near the light sensor to block it.

[0062] Please refer to Figure 1 - Figure 4 It includes a lubricant container 9, and the base 2 is detachably connected to the lubricant container 9.

[0063] In some embodiments, the lubricant container 9 and the base 2 are threadedly connected, and after connection, the outlet of the lubricant container 9 is connected to the oil inlet of the pump 3. This configuration allows for quick and easy replacement of the lubricant container 9 when the lubricant is used up. The lubricant container 9 can be configured with different capacity specifications. Each new lubricant container 9 can be equipped with a new sensor 1; thus, even if the old sensor 1 is lost, a new sensor 1 is provided each time a new lubricant container 9 is replaced.

[0064] Please refer to Figure 1 - Figure 4 , Figure 7 The lubricating fluid container 9 is a piston-pressed disc type liquid tank. The piston disc 910 of the lubricating fluid container 9 is provided with a sensing medium 920. The lubricating fluid container 9 or the base 2 is provided with a second sensor 10 corresponding to the sensing medium 920. The second sensor 10 is used to collect distance information between the sensing medium 920 and the second sensor 10.

[0065] The second sensor 10 is preferably located at a low horizontal position in the lubricant container 9 or the base 2. As the lubricant in the lubricant container 9 is gradually depleted, the piston disc 910 in the lubricant container 9 will move downward under the drive of the corresponding spring, causing the sensing medium 920 to approach the second sensor 10 along with the piston disc 910. When the distance between the second sensor 10 and the sensing medium 920 is very close, it indicates that the lubricant in the lubricant container 9 is about to run out or has already run out. The corresponding control box and alarm electrically connected to the second sensor 10 can provide a notification.

[0066] Please refer to Figure 7 The lubricating fluid container 9 is provided with a support rod 930, and the second sensor 10 is located inside one end of the support rod 930 adjacent to the base 2; the other end of the support rod 930 extends out of the lubricating fluid container 9 and is provided with an information transmission part 1010 of the second sensor 10; the piston disc 910 is sleeved on the support rod 930 and is slidably connected to the support rod 930.

[0067] The information transmission unit 1010 is electrically connected to the corresponding control box, so that the control box receives liquid level information.

[0068] In some embodiments, the second sensor 10 is a magnetic switch and the sensing medium 920 is a magnet.

[0069] If liquid level alarm and liquid level recognition are not required, then there is no need to install the support rod 930, sensing medium 920, and second sensor 10.

[0070] When the lubricating fluid container 9 with sensing medium 920 and second sensor 10 triggers a low liquid level condition, the signal collected by the second sensor 10 will be transmitted to the upper position. The user needs to stop the operation of pump 3 according to this signal to prevent air from entering the oil pipe or the part of the equipment that needs lubrication.

[0071] Please refer to Figure 1 , Figure 2 and Figure 5 , Figure 8 The pump 3 includes a mounting base 310, a motor 320, a reduction gear set 330 connected to the power output shaft of the motor 320, and a screw 340 driven by the reduction gear set 330. The motor 320, the reduction gear set 330, and the screw 340 are all connected to the mounting base 310. The mounting base 310 is provided with an oil inlet (not shown) and an oil outlet 311. The screw 340 is driven to connect or disconnect from the oil inlet and the oil outlet 311.

[0072] The oil outlet 311 can be connected to an oil outlet connector 11, which extends out of the base 2. The oil outlet connector 11 is connected to the distributor 13 through a pipe 12. The distributor 13 can be connected to the location where oil needs to be supplied through multiple distribution pipes 15. The base 2 and the distributor 13 can both be detachably mounted on a connecting seat 16.

[0073] In addition, the oil outlet connector 11 can also be directly connected to the location where oil supply is required.

[0074] This allows for point-to-point installation; it can also be used in combination with the progressive distributor 13 to form a progressive centralized lubrication system.

[0075] In addition, a battery compartment 14 or a DC power supply interface (not shown) can be installed in the base 2 to provide power to electrical components such as the control board 4 and the motor 320. The control board 4 can be equipped with a communication module to communicate with a host computer, enabling the automatic oiler to have remote monitoring capabilities and realize low liquid level and blockage alarm functions at the customer's location. The blockage alarm is determined based on an abnormal increase in the operating current of the motor 320 during operation; after a blockage is detected, the control board 4 can also control the indicator light 6 corresponding to the fault indication text to light up red, which can be a continuous flashing red light that flashes twice. When the battery level in the battery compartment 14 is low, the control board 4 can also control the indicator light 6 corresponding to the low battery indication text to light up orange, which can be a continuous flashing orange light that flashes twice.

[0076] Please refer to Figure 1 and Figure 3 , Figure 4The lubricant container 9 is provided with a connecting protrusion 940; the sensing element 1 includes a cap 120, the outer periphery of which is provided with a holding groove 121; the cap 120 is provided with a connecting groove that matches the connecting protrusion 940.

[0077] This design features a simple structure and is easy to operate.

[0078] The outer contour of the cap body 120 can be the size of a hexagonal nut or a beverage bottle cap, and the user can hold it with one hand.

[0079] The connecting protrusion 940 is preferably located at the top center of the lubricant container 9.

[0080] The magnet 110 is embedded in the end of the cap body 120 in an inlay manner.

[0081] In some embodiments, this active lubricator also has an immediate lubrication mode:

[0082] Before performing immediate lubrication upon startup, ensure that the system is activated and that the monthly settings are complete.

[0083] The steps to initiate immediate lubrication are as follows: first, the sensing element 1 is placed in the area where the first sensor 5 is located;

[0084] Secondly, after indicator light 6 flashes red twice, the sensor 1 is moved away, and the indicator light 6 corresponding to the set month illuminates.

[0085] Finally, immediately lubricate and start the machine.

[0086] The parameters for the immediate lubrication mode are: the total duration of immediate lubrication is approximately 20 seconds, the grease pumping time is approximately 7 seconds, the interval time is approximately 4 seconds, and the pump pumps grease 3 times within 20 seconds. If no grease is discharged from the pump outlet after one immediate lubrication cycle, the immediate lubrication can be restarted to continue venting.
