Description

Technical Field

[0001] The utility model relates to the technical field of air sensors, in particular to a novel intelligent air sensor. Background Art

[0002] The air sensor, also known as the air flow meter, is one of the important sensors of the electronic fuel injection engine. It converts the inhaled air flow into an electrical signal and sends it to the electronic control unit. As one of the basic signals for determining fuel injection, it is a sensor for measuring the air flow rate inhaled into the engine.

[0003] The air sensor determines the injection signal by converting the amount of inhaled air into an electrical signal. Therefore, the air sensor needs to inhale a large amount of air when working, and the environment may be mixed with a large amount of dust. After being inhaled by the air sensor at a very fast speed, the dust will accumulate inside the device, thereby affecting the normal operation of the device. In order to deal with the above problems and defects, a new type of intelligent air sensor is urgently needed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a new type of intelligent air sensor to solve the problem that the existing air sensor judges the injection signal by converting the amount of inhaled air into an electrical signal. Therefore, the air sensor needs to inhale a large amount of air when working, and the environment may be mixed with a large amount of dust. After being inhaled by the air sensor at a very fast speed, the dust will accumulate inside the device, thereby affecting the normal operation of the device.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A novel intelligent air sensor comprises: a sensor body, wherein the outer wall of the sensor body is provided with an air inlet; the inner wall of the air inlet is provided with a circular groove, a spring is fixedly mounted on the top of the inner wall of the circular groove, a connecting block is fixedly mounted on the end of the spring away from the circular groove, a clamping block is fixedly mounted on the side of the connecting block away from the spring, a filter is clamped on the outer wall of the clamping block, a connecting rope is fixedly connected to the side of the connecting block close to the spring, and the connecting rope runs through the air inlet, a swivel is rotatably connected to the outer wall of the air inlet, an end of the connecting rope away from the connecting block is fixedly connected to the swivel, a positioning plate is fixedly mounted on the inner wall of the air inlet, and the positioning plate abuts against the filter.

[0007] The outer wall of the air inlet is provided with a limiting groove, the inner wall of the limiting groove is clamped with a limiting block, and the side of the limiting block away from the limiting groove is fixedly connected to the filter screen.

[0008] An outer wall of the filter screen is provided with an inclined groove, and the inclined groove is located on a side close to the positioning piece.

[0009] A rubber pad is fixedly mounted on one side of the positioning piece close to the filter screen, and the outer wall of the rubber pad abuts against the filter screen.

[0010] The cross-sectional shape of the clamping block is a right-angled trapezoid, and the oblique side of the clamping block is located at a side away from the oblique groove.

[0011] The number of the circular grooves, springs, connecting blocks, clamping blocks and connecting ropes is four, and the four circular grooves, springs, connecting blocks, clamping blocks and connecting ropes are evenly distributed on the circumference of the inner wall of the air inlet.

[0012] Compared with the prior art, the utility model has at least the following beneficial effects:

[0013] 1. In the above scheme, before using the sensor body, the limit block on the side of the filter is first inserted along the limit groove. When the block is squeezed by the filter, the block moves to the depth of the circular groove until the filter is completely inserted into the air inlet and conflicts with the positioning piece. At this time, the block is no longer squeezed, and the connecting block and the block are moved toward the direction of the filter through the action of the spring until they are engaged with the filter. When the operation is completed, the swivel is turned to pull the connecting rope through the rotation of the swivel, and then the connecting block and the block are pulled to the depth of the circular groove through the connecting rope. At this time, the filter can be removed for cleaning, which is beneficial to filtering external dust when the sensor body is operating, ensuring the normal operation of the device, and also convenient for disassembly and assembly of the filter, so as to maintain and clean the filter in time.

[0014] 2. In the above scheme, the positioning piece and the rubber pad are provided, which is conducive to limiting the filter screen. At the same time, the rubber pad has a certain elasticity, so it can provide a thrust for the filter screen to move, thereby improving the stability of the filter screen when it is fixed.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, the embodiment of the utility model provides a new intelligent air sensor, including: a sensor body 1, the sensor body 1 is a new intelligent air sensor, the outer wall of the sensor body 1 is provided with an air inlet 2; the inner wall of the air inlet 2 is provided with a circular groove 3, the top of the inner wall of the circular groove 3 is fixedly equipped with a spring 4 providing elastic force, the end of the spring 4 away from the circular groove 3 is fixedly equipped with a connecting block 5, the side of the connecting block 5 away from the spring 4 is fixedly equipped with a clamping block 6, and the outer wall of the clamping block 6 is clamped with a filter screen 7 for filtering the inhaled air A connecting rope 8 is fixedly connected to the side of the connecting block 5 close to the spring 4, and the connecting rope 8 runs through the air inlet 2. A swivel 9 is rotatably connected to the outer wall of the air inlet 2. The end of the connecting rope 8 away from the connecting block 5 is fixedly connected to the swivel 9. A positioning piece 10 is fixedly assembled on the inner wall of the air inlet 2. The positioning piece 10 abuts against the filter screen 7. The cross-sectional shape of the block 6 is a right-angled trapezoid, and the hypotenuse of the block 6 is located on the side away from the inclined groove 13. By limiting the block 6, it is beneficial to improve the smoothness of the filter screen 7 during installation and improve the efficiency of installation.

[0029] like Figure 1 and Figure 3 As shown, a limiting groove 11 is provided on the outer wall of the air inlet 2, and a limiting block 12 is clamped on the inner wall of the limiting groove 11. The limiting block 12 is fixedly connected to the filter screen 7 on the side away from the limiting groove 11. By setting the limiting groove 11 and the limiting block 12, it is helpful to guide the filter screen 7 when installing the filter screen 7, and at the same time, it can also improve the stability of the filter screen 7 during installation.

[0030] like Figure 2 and Figure 4 As shown, the outer wall of the filter screen 7 is provided with an inclined groove 13, which is located on the side close to the positioning piece 10. The inclined groove 13 is provided to guide the movement of the block 6 when the filter screen 7 contacts the block 6, thereby preventing the block 6 and the filter screen 7 from getting stuck.

[0031] like Figure 2 and Figure 4 As shown, a rubber pad 14 is fixedly mounted on one side of the positioning piece 10 close to the filter screen 7, and the outer wall of the rubber pad 14 abuts against the filter screen 7.

When the clamping block 6 is squeezed by the filter screen 7, the clamping block 6 moves to the depth of the circular groove 3 until the filter screen 7 is completely inserted into the air inlet 2 and conflicts with the positioning piece 10. At this time, the clamping block 6 loses the squeezing, and the connecting block 5 and the clamping block 6 are moved toward the direction of the filter screen 7 by the action of the spring 4 until they are engaged with the filter screen 7. When the operation is completed, the rotating ring 9 is rotated, and the connecting rope 8 is pulled by the rotation of the rotating ring 9, and then the connecting block 5 and the clamping block 6 are pulled to the depth of the circular groove 3 by the connecting rope 8. At this time, the filter screen 7 can be removed for cleaning;

[0034] The positioning piece 10 and the rubber pad 14 are provided to help limit the filter screen 7. Meanwhile, the rubber pad 14 has a certain elasticity, so it can provide a thrust for the filter screen 7 to move, thereby improving the stability of the filter screen 7 when it is fixed.
