[0026] 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 embodiments of the present invention, and not all embodiments. 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.

[0027] Please see Figures 1-8 An oil filter labyrinth regulating oil inlet device includes a housing 1. A pre-filter 3 is connected to the front end of the housing 1 via an oil inlet pipe 2. An oil passage plate 4 is installed inside the housing 1. A first oil passage 5 is formed on the top surface of the front end of the oil passage plate 4. The first oil passage 5 has three bends: a first bend 6, a second bend 7, and a third bend 8. The first bend 6 connects to a second oil passage 9, the second bend 7 connects to a third oil passage 10, and the third bend 8 connects to a fourth oil passage 11. The ends of the first oil passage 5, the second oil passage 9, the third oil passage 10, and the fourth oil passage 11 are all connected to an oil outlet 12. The second oil passage 9 and the third oil passage 10... A receiving groove 13 is provided at the side end of the connection between the fourth oil passage 11 and the first oil passage 5. A stop block 14 is provided inside the receiving groove 13. An adjusting rod 15 passes through the stop block 14. By setting multiple labyrinth-shaped oil passages at the top of the oil passage plate 4, when adjusting the oil volume, the adjusting rod 15 is rotated, so that the stop block 14 with its outer wall threaded connection moves back and forth in the moving groove, thereby controlling the opening and closing of the second oil passage 9, the third oil passage 10 and the fourth oil passage 11, realizing the adjustment of the oil intake. This solves the problem that the existing technology lacks control over the oil intake, which leads to the lubricating oil dripping too fast under high ambient temperature conditions, resulting in increased oil consumption.

[0028] Please see Figure 1 and Figure 5 The oil circuit board 4 is enclosed inside the outer shell 1. It collects the oil inflow from each oil circuit through the oil outlet 12 and then delivers it to the outside through the oil outlet pipe 16 connected to it.

[0029] Please see Figure 2 , Figure 7 and Figure 8The first oil path 5 is arranged in an S-shaped bending shape, facilitating connection of the second oil path 9, the third oil path 10 and the fourth oil path 11 at each bending position. The front end oil inlet of the first oil path 5 is arranged to have a size equal to that of the oil inlet pipe 2 and greater than the width of the first oil path 5, so that the initial oil inlet amount of the first oil path 5 is large, and when other oil paths are opened, oil can be quickly supplied to other oil paths, the flow rate is improved, and the effect of increasing the oil inlet amount is achieved.

[0030] Referring to Figure 2 and Figure 8 The three bending positions of the first oil path 5 are arranged opposite to each other, facilitating separate arrangement of the second oil path 9, the third oil path 10 and the fourth oil path 11, so that lubricating oil can be introduced on both sides of the oil outlet 12, facilitating layout of the oil path plate 4 while preventing excessive impact on one side of the oil outlet 12.

[0031] Referring to Figure 2 and Figure 7-8 The second oil path 9 and the fourth oil path 11 are located on the same side of the oil path plate 4, facilitating subsequent simultaneous control of the opening and closing of the two oil paths by the adjusting rod 15, without the need for separate structure control on the same side of the shell 1, saving the internal space of the shell 1 and preventing lubricating oil from leaking to other places inside the shell 1.

[0032] Referring to Figures 3-4 and Figures 7-8 The side ends of the second oil path 9, the third oil path 10 and the fourth oil path 11 at the connection positions with the first oil path 5 are provided with accommodating grooves 13 for providing space for movement of the stop block 14 to open and close the second oil path 9, the third oil path 10 and the fourth oil path 11. When the stop block 14 moves into the accommodating groove 13, the second oil path 9, the third oil path 10 and the fourth oil path 11 are in communication with the first oil path 5. When the stop block 14 exits the accommodating groove 13, the communication between the second oil path 9, the third oil path 10 and the fourth oil path 11 and the first oil path 5 is closed, thereby closing the oil paths. The width of the accommodating groove 13 is equal to the channel width of the above-mentioned four oil paths, and the thickness of the stop block 14 is equal to the width of the accommodating groove 13, so that when the stop block 14 exits the inside of the accommodating groove 13, the communication between each oil path and the first oil path 5 is just cut off, preventing leakage of lubricating oil and affecting adjustment of the oil inlet amount.

[0033] Referring to Figures 3-4 and Figures 7-8The top end of the stopper 14 is screwed with the adjusting rod 15, and a moving groove corresponding to the containing groove 13 is opened inside the top end of the shell 1, which can provide the adjusting rod 15 with moving space to control the stopper 14, and the stopper 14 can move back and forth to switch positions at the connecting position of the containing groove 13 and each oil path to open and close the oil path. The stopper 14 inside the containing groove 13 at the side end of the second oil path 9 and the fourth oil path 11 is controlled by the same adjusting rod 15, so that the adjusting rod 15 can control the two groups of stoppers 14 to move at the same time when rotating, thereby achieving the control of opening and closing of the two oil paths at the same time.

[0034] Please refer to Figures 7-8 and ​ The front section of the adjusting rod 15 is provided with a thread on the outer wall with the same moving stroke range of the stopper 14, which can be screwed with the stopper 14 to adjust the position of the stopper 14 when rotating. The remaining part of the adjusting rod 15 is provided with a smooth outer wall, so that the adjusting rod 15 can rotate inside the sealing ring without damaging the sealing ring and affecting the sealing effect. The adjusting rod 15 penetrates through the shell 1 and extends to the outside of the shell 1, and the hand wheel is used to rotate and control the adjusting rod 15.

[0035] Please refer to ​ The outer wall at the connecting position of the adjusting rod 15 and the moving groove and the outer wall at the connecting position of the adjusting rod 15 and the end of the shell 1 are provided with a sealing ring, which can seal the connecting position of the adjusting rod 15 and the moving groove and the shell, so as to avoid the lubricating oil flowing out of the shell 1 when the adjusting rod 15 rotates, thereby preventing the lubricating oil from leaking.

[0036] In use, the lubricating oil is filtered by the pre-filter 3, and then enters the first oil path 5 at the top end of the oil path plate 4 inside the shell 1 through the oil inlet pipe 2, and then enters the oil outlet 12 through the first oil path 5, and is then delivered to the outside through the oil outlet pipe 16. In the initial state, the stop blocks 14 are all located at the connection between the first oil path 5 and each oil path, at this time, each oil path is in a closed state. When adjusting the oil inlet amount, the hand wheel at the end of the adjusting rod 15 controlling the third oil path 10 is rotated, the adjusting rod 15 is rotated, and the stop block 14 threadedly connected to the front end of the adjusting rod 15 is moved from the connection between the third oil path 10 and the first oil path 5 to the inside of the containing groove 13, so as to open the third oil path 10, and the lubricating oil enters the oil outlet 12 and the lubricating oil inside the first oil path 5 through the third oil path 10. At this time, two oil paths supply oil at the same time, and the oil inlet amount is increased. The hand wheel at the end of the adjusting rod 15 controlling the second oil path 9 and the fourth oil path 11 is further rotated, the adjusting rod 15 is rotated, and the stop block 14 threadedly connected to the front end of the adjusting rod 15 is moved from the connection between the second oil path 9 and the fourth oil path 11 and the first oil path 5 to the inside of the containing groove 13, so as to open the second oil path 9 and the fourth oil path 11, and the lubricating oil enters the oil outlet 12 and the lubricating oil inside the first oil path 5 and the third oil path 10 through the second oil path 9 and the fourth oil path 11. At this time, the whole oil filter reaches the maximum oil inlet amount. The above operation is reversed, and the oil inlet amount can be adjusted to be small, so as to realize multi-stage adjustment of the whole oil inlet amount.

[0037] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
