Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of filter heating, and in particular to a diesel filter heating device with a drainage function. Background Art
[0002] A traditional primary fuel filter typically consists of a filter housing, a filter element, a filter holder, and a manual fuel pump. The lower end of the filter element features a filter housing that collects oil, impurities, and water. This housing is equipped with a drain plug, allowing the operator to periodically drain accumulated water and dirt based on their experience. Due to human error, it's inevitable that operators may forget to clean the filter or prematurely clean it out of fear of filling it with water. The presence of water can damage high-precision, high-atomization fuel injectors. Because traditional fuel filters are no longer suitable for the operating requirements of modern engines, they are being gradually replaced with oil-water separators. Accordingly, the impurity separation method has also been changed from natural water sedimentation to forced separation using special filter paper cores. Currently, various oil purification devices are all operated in sealed containers. Because water filtered through the filter core tends to settle at the bottom of the purification device, if a certain amount of water is not promptly removed, it can reduce the filter core's efficiency and damage it. Furthermore, water can enter the filtered oil, causing engine damage. Therefore, when there is too much water, it must be drained. Therefore, prompting the operator to drain the accumulated water is crucial. In the prior art, a water level sensor is installed in the water collection cup. When the water level is too high, an alarm is issued to remind the driver to drain the water. However, in the prior art, drainage is always performed manually, and the drain hole is relatively small, resulting in slow drainage. Therefore, some careless drivers may forget to close the water-proof hole or leave it loose, causing oil to leak out through the hole, causing damage to the vehicle and posing a significant safety hazard.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Example
[0021] like Figure 1-4As shown, the present invention provides a diesel filter heating device with a drainage function, comprising a water collecting cup 1, a connecting pipe 11 installed at the bottom of the water collecting cup 1, a mounting base 21 installed in the water collecting cup 1, a heater 2 installed on the mounting base 21, and a double-contact water level sensor 3 installed at the bottom of the water collecting cup 1. When the water level sensor 3 detects a high water level, it will sound an alarm, and the driver will know that drainage is required. To facilitate drainage, a drainage hole is installed at the bottom of the water collecting cup 1, and a drainage device 4 is installed at the drainage hole. The drainage device 4 includes a drainage bucket 41, the barrel mouth of the drainage bucket 41 is set downward and fixed in the drainage hole, and a through hole 42 is provided on one side of the drainage bucket 41. The through hole 42 connects the drainage bucket 41 to the water collecting cup 1, and a water retaining member is slidably connected in the drainage bucket 41. The water retaining member comprises a first piston plate 51 and a second piston plate 52, which are connected by a connecting rod 512. Both the first and second piston plates 51, 52 are slidingly and sealingly connected within the drain bucket 41. The first piston plate 51 is provided with a water-permeable hole 511. A contact sensor 43 is mounted on the wall of the drain bucket 41. When the contact sensor 43 is positioned relative to the first piston plate 51, the second piston plate 52 is positioned below the through-hole 42, preventing water within the through-hole 42 from draining through the water-permeable hole 511. Drain bucket 41 has an air hole at the bottom. A first connector pipe 58 is installed at one end of the bucket, connected to an alarm device 6 via a hose 59. Alarm device 6 comprises a barrel body 61, with a second connector pipe 62 at the bottom, which connects to hose 59. A fourth piston plate 63 is slidably connected to the inside of barrel body 61, and a pressure rod 64 is fixedly connected to one side of the fourth piston plate 63. A lid 69 is fixedly connected to the mouth of barrel body 61. A push-button switch 65 is mounted inside lid 69, which controls a buzzer alarm located in the cab. The push-button switch 65 is positioned opposite pressure rod 64. A guide hole is provided on one side of lid 69, into which a guide rod 67 is slidably connected. One end of guide rod 67 is fixed to fourth piston plate 63. A spring 68 is sheathed around the outside of guide rod 67 and secured between lid 69 and fourth piston plate 63. A breathing hole 66 is also provided in lid 69. A third piston plate 53 is slidably connected to the drain bucket 41 and secured above the second piston plate 52 via a fixing rod 521. A crossbeam 54 is mounted within the drain bucket 41, with a threaded hole defined in it. An adjustment shaft 55 is pivotally connected to the underside of the first piston plate 51. A threaded section 56 is located in the middle of the adjustment shaft 55 and is threadedly engaged within the threaded hole. The lower end of the adjustment shaft 55 is fixedly connected to an adjustment block 561, which has a hexagonal hole 562 defined in its underside.
[0022] During operation, when it is necessary to drain water, the driver inserts the inner hexagon into the hexagonal hole 562 to rotate the adjusting block 561, so that the adjusting shaft 55 rotates, and the first piston plate 51 and the second piston plate 52 move upward under the action of the threaded section 56. When the second piston plate 52 is located above the through hole, the water in the water collecting cup 1 will flow from the through hole into the space between the first piston plate 51 and the second piston plate 52, and be discharged from the water permeable hole 511. When the second piston plate 52 rises, the third piston plate 53 will also move upward. During the upward movement of the third piston plate 53, the air in the drainage bucket 41 will be compressed. Under the action of the pressure of the compressed air, a thrust is generated on the fourth piston plate 63, and the fourth piston plate 6 3 moves horizontally, so that the pressure rod 64 presses the push switch 65. At this time, the buzzer alarm continues to sound an alarm, so that the driver will not forget to reset the drainage part due to other trivial matters. When the waterproofing is completed, the adjusting shaft is rotated in the opposite direction so that the second piston plate 52 is located above the through hole. At this time, the second piston plate seals the through hole, and the fourth piston plate 63 is reset under the action of the spring, so that the pressure rod 64 is away from the push switch 65. At this time, the first piston plate is in contact with the contact sensor. The contact sensor transmits a signal, indicating that the drainage through hole has been blocked, thereby preventing the driver from easily forgetting to close the waterproof hole or the waterproof hole is not closed tightly, eliminating such safety hazards.
