Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of voltage regulators, and in particular to a signal metering device for a voltage regulator. BACKGROUND

[0002] A voltage regulator is an electronic device or circuit component used to automatically maintain the stability of the output voltage. Its core function is to stabilize the output voltage within a preset range through a feedback control mechanism when the input voltage fluctuates or the load changes. The voltage regulator is usually equipped with a signal metering device, which is a device or system used to monitor, measure and feedback key parameters (such as voltage, current, power, etc.) in the running state of the voltage regulator. Its core function is to collect electrical signals through sensors, and after conversion and processing, provide data support for the control or protection system of the voltage regulator, ensuring that the output voltage is stable within the set range.

[0003] In the prior art, a signal metering module is installed on the outer wall of the voltage regulator, and the signal metering module is connected to the internal circuit of the voltage regulator through a line to collect electrical signal data. In the working state, the internal electronic components and coils of the voltage regulator generate a large amount of heat, while the signal metering module generates less heat due to its low power consumption. Therefore, during product design, the focus is mainly on heat dissipation of the voltage regulator to ensure stable operation of the voltage regulator.

[0004] Although the signal metering module generates relatively less heat, it is directly connected to the voltage regulator, and the heat generated by the voltage regulator can easily be transferred to the signal metering module, thereby passively increasing the temperature of the signal metering module. In addition, for some special working conditions, for example, when the signal metering module continuously processes large current or high voltage signals for a long time, the power consumption of the internal components of the signal metering module will significantly increase, reducing its performance stability and service life, so further improvement is needed. SUMMARY

[0005] In order to reduce the possibility of passive temperature rise of the signal metering module, the present application provides a signal metering device for a voltage regulator.

[0006] The signal metering device for a voltage regulator provided by the present application adopts the following technical scheme: A signal metering device for a voltage regulator, comprising a voltage regulator main body and a signal metering module, wherein the outer wall of the voltage regulator main body is provided with a mounting seat, the side wall of the mounting seat is provided with a mounting groove, the signal metering module is embedded in the mounting groove and forms a cavity together with the mounting seat, and the cavity is located between the signal metering module and the voltage regulator main body; the voltage regulator main body has a heat dissipation flow channel inside, the mounting seat is provided with a suction flow channel, one end of the suction flow channel communicates with the cavity, and the other end of the suction flow channel communicates with the heat dissipation flow channel; the side wall of the mounting groove is provided with a gas supplement flow channel communicating with the cavity.

[0007] By adopting the technical scheme, in the working state, cooling gas is introduced into the heat dissipation flow channel in the pressure regulator main body to take away the heat generated during the operation of the pressure regulator main body, and the stable operation of the internal components of the pressure regulator main body is ensured. The cavity is arranged between the signal measurement module and the pressure regulator main body, the cavity is communicated with the outside through the air supplement flow channel, and the cavity is communicated with the heat dissipation flow channel through the adsorption flow channel. According to Bernoulli's principle, because the heat dissipation flow channel has gas flowing through, the air pressure in the heat dissipation flow channel is lower than that in the cavity, so that the gas in the cavity is sucked into the heat dissipation flow channel through the adsorption flow channel to take away the heat in the cavity (part of the heat in the cavity comes from the signal measurement module, and part of the heat comes from the pressure regulator main body), thereby reducing the possibility that the signal measurement module is passively raised in temperature due to heat transfer from the pressure regulator main body, and further ensuring the stable operation of the signal measurement module.

[0008] Optionally, a plurality of heat dissipation rings are arranged in the pressure regulator main body, the heat dissipation rings are hollow and form the heat dissipation flow channel, the outer wall of the heat dissipation ring is embedded with a plurality of heat dissipation fins, the plurality of heat dissipation fins are arranged at intervals around the virtual central axis of the heat dissipation ring, and each heat dissipation fin locally extends into the heat dissipation flow channel.

[0009] By adopting the technical scheme, the heat generated in the pressure regulator main body is conducted to the heat dissipation flow channel by the heat dissipation fins, and cooling gas is introduced into the heat dissipation flow channel to take away the heat. The cooling gas is limited in the heat dissipation ring, so that the cooling gas does not come into contact with the internal components of the pressure regulator main body, and the possibility that foreign matters such as floating dust from the outside are brought into the pressure regulator main body is reduced.

[0010] Optionally, the heat dissipation ring comprises a circular arc segment and a straight line segment, the outer wall of the straight line segment is connected with a branch pipe, one end of the branch pipe is communicated with the straight line segment, and the other end of the branch pipe is communicated with the adsorption flow channel; and the included angle between the airflow direction in the branch pipe and the airflow direction in the straight line segment is an acute angle.

[0011] By adopting the technical scheme, the included angle between the airflow direction in the branch pipe and the airflow direction in the straight line segment is set to an acute angle, the difficulty of the gas in the heat dissipation flow channel entering the branch pipe is increased, and the air in the cavity is ensured to be sucked into the heat dissipation flow channel through the adsorption flow channel.

[0012] Optionally, a switch plate is slidably installed in the mounting groove, a return spring is arranged between the switch plate and the mounting seat, the return spring forces the switch plate to close the adsorption flow channel, and a driving assembly is arranged in the mounting groove, when the signal measurement module is embedded in the mounting groove, the driving assembly forces the switch plate to slide and open the adsorption flow channel.

[0013] Optionally, the drive assembly includes a sliding plate and a flipping rod. The sliding plate is slidably installed in the mounting groove, and the flipping rod is hinged to the inner wall of the mounting groove. One end of the flipping rod abuts against the sliding plate, and the other end has a pushing groove. The side wall of the opening and closing plate is provided with a pushing post that inserts into the pushing groove. When the signal metering module is embedded in the mounting groove, the signal metering module pushes the flipping rod through the sliding plate and forces the opening and closing plate to slide towards the side closer to the signal metering module.

[0014] By adopting the above technical solution, when the signal metering module is embedded in the mounting slot, the signal metering module pushes one end of the flipping rod through the sliding plate, thereby causing the flipping rod to flip at a certain angle. The flipping rod pushes the pushing column through the inner wall of the pushing slot, thereby causing the opening and closing plate to slide towards the side closer to the signal metering module, so as to open the adsorption flow channel and improve the operational convenience of the overall structure.

[0015] Optionally, the sliding plate has an inlet groove on its surface near the signal metering module. One end of the inlet groove is connected to the air supply channel, and the other end is connected to the cavity. The airflow direction in the inlet groove is parallel to the surface of the signal metering module near the opening and closing plate. The openings at both ends of the inlet groove gradually expand from the end near the air supply channel to the end away from the air supply channel.

[0016] By adopting the above technical solution, and by setting an inlet slot, the air supply channel and the cavity can be connected after the signal metering module is embedded in the mounting slot. The airflow direction in the inlet slot is parallel to the surface of the signal metering module near the opening and closing plate, so that the gas blown in by the air supply channel acts on the surface of the signal metering module near the opening and closing plate, thereby improving the heat dissipation effect of the signal metering module.

[0017] Optionally, two sliding plates are provided in the mounting groove, with a first flow port formed between the two sliding plates at an interval; a second flow port is formed between the surface of the opening and closing plate and the surface of the two sliding plates, and the airflow introduced by the inlet groove enters the adsorption channel through the first flow port and the second flow port in sequence.

[0018] By adopting the above technical solution, the gas flowing into the air supply channel is made to flow in an "S" shape in the cavity using the opening and closing plate and two sliding plates, so as to fully contact the opening and closing plate and the sliding plate and remove the heat from the surface of the opening and closing plate and the sliding plate.

[0019] Optionally, the regulator body is provided with an air inlet channel and an air outlet channel, and the heat dissipation ring includes an air inlet section and an air outlet section. One end of the air inlet section is connected to the air inlet channel, and one end of the air outlet section is connected to the air outlet channel. A switching seat is provided between the air inlet section and the air outlet section. A switching cavity is opened in the switching seat. The air inlet section, the air outlet section, and the adsorption channel are all connected to the switching cavity. A switching component is provided in the switching seat. The switching component is used to switch the airflow in the air inlet section to the air outlet section or the adsorption channel.

[0020] By adopting the above technical solution, under normal conditions, the air inlet section is forced to face the air outlet section. Cooling gas is introduced into the air inlet section through the air inlet channel, and the cooling gas passes through the air inlet section and the air outlet section in sequence, and is discharged outward through the air outlet channel. When the supplementary airflow channel becomes blocked (due to the introduction of foreign objects such as lint into the supplementary airflow channel during long-term operation), the air inlet section is switched to a downward adsorption channel by the switching component, so that the gas introduced into the air inlet section directly enters the cavity, thereby blowing out the foreign objects in the supplementary airflow channel and improving the stability of the overall structure.

[0021] Optionally, the switching assembly includes a switching ball and a rotating component. The switching ball is rotatably installed inside the switching cavity. A first switching channel and a second switching channel are respectively opened inside the switching ball. Both ends of the first switching channel penetrate the surface of the switching ball. One end of the second switching channel is connected to the first switching channel, and the other end penetrates the surface of the switching ball. When one end of the first switching channel rotates to connect with the air inlet section, the other end of the first switching channel is connected to the air outlet section, and the second switching channel is connected to the adsorption flow channel. When the second switching channel rotates to connect with the air inlet section, one end of the first switching channel is closed, and the other end is connected to the adsorption flow channel. The rotating component is disposed on the opening and closing plate to drive the switching ball to rotate.

[0022] By adopting the above technical solution, under normal conditions, one end of the first switching channel is rotated to connect with the intake section, while the other end of the first switching channel connects to the exhaust section, and the second switching channel connects to the adsorption channel. This allows cooling gas to be introduced into the heat dissipation channel, which can both remove heat from the regulator body and adsorb air from the cavity into the heat dissipation channel. When it is necessary to clean the make-up air channel, the switching ball is driven to rotate by the rotating component, forcing the second switching channel to connect with the intake section. At this time, one end of the first switching channel is closed, and the other end connects to the adsorption channel, allowing cooling gas in the heat dissipation channel to directly enter the cavity, blowing out foreign matter in the make-up air channel and improving the stability of the overall structure.

[0023] Optionally, the rotating component includes a drive sleeve and a rotating rod. The drive sleeve is disposed on the opening and closing plate. One end of the rotating rod is connected to the switching ball, and the other end passes through the drive sleeve. The inner peripheral wall of the drive sleeve is provided with a drive column. The outer peripheral wall of the end of the rotating rod away from the switching ball is provided with a guide groove for the drive column to be embedded. When the signal metering module is pushed into the cavity, the drive column drives the rotating rod to rotate through the guide groove.

[0024] By adopting the above technical solution, when it is necessary to clean the air supply channel, pressing the signal metering module forces it to slide towards the side closer to the regulator body, thereby causing the opening and closing plate to continue sliding towards the side closer to the signal metering module. The drive sleeve on the opening and closing plate pushes the inner wall of the guide groove of the rotating rod through the drive column, thereby forcing the switching ball to rotate, so that the second switching channel rotates to connect with the air intake section. This allows the cooling gas in the heat dissipation channel to directly enter the cavity, blowing out foreign objects in the air supply channel and improving the overall ease of operation.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the design of the cavity and adsorption channel, cooling gas is introduced into the heat dissipation channel inside the voltage regulator body during operation to remove the heat generated inside the voltage regulator body, ensuring the stable operation of the internal components. The cavity is connected to the heat dissipation channel through the adsorption channel. According to Bernoulli's principle, because gas flows through the heat dissipation channel, the gas pressure inside the heat dissipation channel is lower than the gas pressure inside the cavity. This draws the gas from the cavity into the heat dissipation channel through the adsorption channel, removing the heat from the cavity and reducing the possibility of the signal metering module being passively heated due to heat transfer from the voltage regulator body, thereby ensuring the stable operation of the signal metering module. 2. By setting up the inlet slot, the air supply channel and the cavity can be connected after the signal metering module is embedded in the mounting slot. The airflow direction in the inlet slot is parallel to the plate surface of the signal metering module near the opening and closing plate, so that the gas blown in by the air supply channel acts on the plate surface of the signal metering module near the opening and closing plate, thereby improving the heat dissipation effect of the signal metering module; 3. By adjusting the switching component settings, when it is necessary to clean the air supply channel, press the signal metering module to force it to slide closer to the regulator body. This causes the opening and closing plate to continue sliding closer to the signal metering module. The drive sleeve on the opening and closing plate pushes the inner wall of the guide groove of the rotating rod through the drive column, thereby forcing the switching ball to rotate and making the second switching channel rotate to connect with the intake section. This allows the cooling gas in the heat dissipation channel to directly enter the cavity, blowing out foreign objects in the air supply channel and improving the overall ease of operation.

[0028] The following combination Figures 1-10 This application will be described in further detail.

[0029] Example 1: This application discloses a signal metering device for a voltage regulator.

[0030] Reference Figure 1 , Figure 2 A signal metering device for a voltage regulator includes a voltage regulator body 1 and a signal metering module 2 (both the voltage regulator body 1 and the signal metering module 2 are existing technologies, and their structures and functions will not be described in detail here, and the internal components of the voltage regulator body 1 and the signal metering module 2 are not shown in the figure). Multiple heat dissipation rings 12 are installed inside the voltage regulator body 1. The multiple heat dissipation rings 12 are arranged at intervals along the height direction of the voltage regulator body 1. The heat dissipation rings 12 are hollow to form heat dissipation channels 11.

[0031] Reference Figure 2 , Figure 3 Each heat dissipation ring 12 has multiple heat dissipation fins 13 embedded in its outer wall. The heat dissipation fins 13 can be made of aluminum. The multiple heat dissipation fins 13 are arranged at intervals around the virtual central axis of the heat dissipation ring 12, and each heat dissipation fin 13 extends partially into the heat dissipation channel 11. One end of the heat dissipation fin 13 extends out of the heat dissipation channel 11 and is fixedly connected to the inner wall of the voltage regulator body 1. The heat dissipation fin 13 and the inner wall of the voltage regulator body 1 can be connected and fixed by welding or bolts.

[0032] ReferenceFigure 2 , Figure 4 The regulator body 1 has an air inlet channel 14 and an air outlet channel 15 inside. In this embodiment, the heat dissipation ring 12 includes an arc segment 121 and a straight segment 122. There are two arc segments 121, which are respectively connected to the two ends of the straight segment 122. One arc segment 121 is connected to the air inlet channel 14 at the end away from the straight segment 122, and the other arc segment 121 is connected to the air outlet channel 15 at the end away from the straight segment 122.

[0033] The intake channel 14 is used to introduce cooling gas, and the exhaust channel 15 is used to discharge cooling gas. In this embodiment, both the introduction and discharge of cooling gas can be carried out by a fan; that is, a fan (not shown in the figure) is installed at the opening of the intake channel 14 to blow outside air into the intake channel 14. To ensure sufficient airflow power, a fan can also be installed in the exhaust channel 15 to blow the air in the exhaust channel 15 outward. In other embodiments, the intake channel 14 can also be connected to an external air pipe for charging cooling gas.

[0034] Reference Figure 1 , Figure 4 A mounting base 3 is fixedly installed on the outer wall of the voltage regulator body 1. A mounting groove 31 is opened on the side wall of the mounting base 3 away from the voltage regulator body 1, and the signal metering module 2 is embedded in the mounting groove 31. A locking bolt 36 is installed on the side wall of the mounting base 3. The locking bolt 36 can be a wing bolt. The locking bolt 36 passes through the mounting plate and abuts against the side wall of the signal metering module 2. The signal metering module 2 can be detachably installed in the mounting groove 31 by means of the locking bolt 36.

[0035] A cavity 32 is formed between the signal metering module 2 and the mounting base 3, and the cavity 32 is located between the signal metering module 2 and the voltage regulator body 1. An adsorption channel 33 is provided inside the mounting base 3, with one end of the adsorption channel 33 connected to the cavity 32. A branch pipe 123 is fixedly connected to the outer wall of the straight section 122, with one end of the branch pipe 123 connected to the interior of the straight section 122 and the other end connected to the adsorption channel 33. The end of the adsorption channel 33 away from the cavity 32 is connected to the heat dissipation channel 11 through the branch pipe 123. In this embodiment, the angle between the airflow direction in the branch pipe 123 and the airflow direction in the straight section 122 is an acute angle.

[0036] The inner wall of the mounting slot 31 is provided with multiple air supply slots. One end of the air supply slot penetrates the side wall of the mounting base 3 away from the regulator body 1. When the signal metering module 2 is embedded in the mounting slot 31, the signal metering module 2 and the inner wall of the air supply slot together form an air supply channel 34. The cavity 32 is connected to the outside through the air supply channel 34.

[0037] The implementation principle of Embodiment 1 of this application is as follows: In the working state, air is blown into the heat dissipation channel 11 through the air intake channel 14. The air enters the heat dissipation channel 11 within the heat dissipation ring 12 and is discharged outward through the air outlet channel 15. The heat generated inside the voltage regulator body 1 is conducted to the heat dissipation channel 11 by the heat sink 13. When the air passes through the heat dissipation channel 11, it can carry away the heat, ensuring the stable operation of the internal components of the voltage regulator body 1. The airflow is restricted within the heat dissipation ring 12, so that the air does not come into contact with the internal components of the voltage regulator body 1 when carrying away heat, reducing the possibility of the cooling gas bringing foreign objects such as lint into the voltage regulator body 1.

[0038] A cavity 32 is provided between the signal metering module 2 and the voltage regulator body 1. The cavity 32 is connected to the outside through a supplementary airflow channel 34, and is also connected to the heat dissipation channel 11 through an adsorption channel 33. According to Bernoulli's principle, since gas flows through the heat dissipation channel 11, the air pressure inside the heat dissipation channel 11 is lower than the air pressure inside the cavity 32. This draws the gas inside the cavity 32 into the heat dissipation channel 11 through the adsorption channel 33, thereby removing the heat from the cavity 32 (part of the heat in the cavity 32 comes from the signal metering module 2, and the other part comes from the voltage regulator body 1). This reduces the possibility of the signal metering module 2 being passively heated due to heat transfer from the voltage regulator body 1, and also removes the heat generated during the operation of the signal metering module 2, thus ensuring the stable operation of the signal metering module 2.

[0039] Example 2: This application discloses a signal metering device for a voltage regulator.

[0040] The signal metering device for a voltage regulator disclosed in this application differs from that in Embodiment 1 in that: Reference Figure 5 , Figure 6 In this embodiment, a closing plate 35 is slidably installed in the mounting groove 31, and a return spring 351 is installed between the closing plate 35 and the mounting base 3. Under normal conditions, the return spring 351 forces the closing plate 35 to close in the adsorption channel 33. A driving component 4 is provided in the mounting groove 31. When the signal metering module 2 is embedded in the mounting groove 31, the driving component 4 forces the closing plate 35 to slide away from the voltage regulator body 1 and open the adsorption channel 33.

[0041] The drive assembly 4 includes a sliding plate 41 and a flipping rod 42. The sliding plate 41 is slidably installed in the mounting groove 31. A rotating shaft is fixedly installed at the middle position of the flipping rod 42, and the rotating shaft is rotatably installed on the inner wall of the mounting groove 31. The flipping rod 42 is hinged to the inner wall of the mounting groove 31 through the rotating shaft. One end of the flipping rod 42 abuts against the sliding plate 41, and the other end has a pushing groove 421. A pushing column 352 is fixedly installed on the side wall of the opening and closing plate 35, and the pushing column 352 is inserted into the pushing groove 421. When the signal measuring module 2 is embedded in the mounting groove 31, the signal measuring module 2 pushes the flipping rod 42 through the sliding plate 41, forcing the opening and closing plate 35 to slide towards the side closer to the signal measuring module 2.

[0042] It should be noted that in this embodiment, there are two sliding plates 41, and the flipping rod 42 and the pushing column 352 corresponding to the sliding plates 41 are arranged accordingly. The two sliding plates 41 are spaced apart to form a first flow port 412; a second flow port 413 is formed between the surface of the opening and closing plate 35 and the surface of the two sliding plates 41.

[0043] Each sliding plate 41 has multiple inlet slots 411 on its surface near the signal metering module 2. These slots are spaced apart along the height direction. One end of each slot 411 connects to the supplementary airflow channel 34, and the other end connects to the cavity 32. The airflow direction within the inlet slot 411 is parallel to the surface of the signal metering module 2 near the opening / closing plate 35. The openings at both ends of the inlet slot 411 gradually widen from the end closer to the supplementary airflow channel 34 to the end farther away. The airflow introduced through the inlet slot 411 sequentially enters the adsorption channel 33 through the first flow port 412 and the second flow port 413.

[0044] The signal metering module 2 has a limiting groove 21 on its side wall. The length direction of the limiting groove 21 is consistent with the length direction of the sliding plate 41. The locking bolt 36 passes through the limiting groove 21 and abuts against the inner wall of the limiting groove 21. This design uses the limiting groove 21 to limit the locking bolt 36, reducing the possibility that the spring force of the return spring 351 will cause the sliding plate 41 to push the signal metering module 2 outward, thus improving the installation stability of the signal metering module 2.

[0045] The implementation principle of Embodiment 2 of this application is as follows: When the signal metering module 2 is embedded in the mounting slot 31, the signal metering module 2 pushes one end of the flipping rod 42 through the sliding plate 41, thereby causing the flipping rod 42 to flip at a certain angle. The flipping rod 42 pushes the pushing column 352 through the inner wall of the pushing slot 421, thereby causing the opening and closing plate 35 to slide towards the side closer to the signal metering module 2, so as to open the adsorption flow channel 33 and improve the operational convenience of the overall structure.

[0046] By setting the inlet slot 411, after the signal metering module 2 is embedded in the mounting slot 31, the air supply channel 34 can communicate with the cavity 32. The airflow direction in the inlet slot 411 is parallel to the plate surface of the signal metering module 2 near the opening and closing plate 35, so that the gas blown in by the air supply channel 34 acts on the plate surface of the signal metering module 2 near the opening and closing plate 35, thereby improving the heat dissipation effect of the signal metering module 2.

[0047] Example 3: This application discloses a signal metering device for a voltage regulator.

[0048] The difference between the signal metering device for a voltage regulator disclosed in this application and embodiment 2 is that: Reference Figure 7 , Figure 8 , Figure 9 In this embodiment, the heat dissipation ring 12 includes an air inlet section 124 and an air outlet section 125. One end of the air inlet section 124 is connected to the air inlet channel 14, and one end of the air outlet section 125 is connected to the air outlet channel 15. A switching seat 5 is fixedly installed on the inner wall of the regulator body 1, and the switching seat 5 is located between the air inlet section 124 and the air outlet section 125. A switching cavity 51 is opened in the switching seat 5. The end of the air inlet section 124 away from the air inlet channel 14, the end of the air outlet section 125 away from the air outlet channel 15, and the end of the adsorption channel 33 away from the cavity 32 are all connected to the switching cavity 51.

[0049] A switching assembly 6 is provided inside the switching seat 5. The switching assembly 6 is used to switch the direction of the airflow in the intake section 124 to the outlet section 125 or the adsorption channel 33. The switching assembly 6 includes a switching ball 61 and a rotating component. The switching ball 61 is rotatably installed in the switching cavity 51. A first switching channel 611 and a second switching channel 612 are respectively opened in the switching ball 61. Both ends of the first switching channel 611 penetrate the surface of the switching ball 61. One end of the second switching channel 612 is connected to the first switching channel 611, and the other end penetrates the surface of the switching ball 61.

[0050] The inner wall of the adsorption channel 33 is provided with a bypass channel 331, which connects to the switching chamber 51. When one end of the first switching channel 611 rotates to connect with the air inlet section 124, the other end of the first switching channel 611 connects to the air outlet section 125, and the second switching channel 612 connects to the bypass channel 331 of the adsorption channel 33. When the second switching channel 612 rotates to connect with the air inlet section 124, one end of the first switching channel 611 closes, and the other end of the first switching channel 611 connects to the bypass channel 331 of the adsorption channel 33.

[0051] Reference Figure 7 , Figure 10A rotating component is disposed on the opening and closing plate 35 to drive the switching ball 61 to rotate. In this embodiment, the rotating component includes a drive sleeve 62 and a rotating rod 63. The drive sleeve 62 is fixedly installed on the opening and closing plate 35. One end of the rotating rod 63 is fixedly connected to the switching ball 61, and the other end passes through the adsorption channel 33 into the cavity 32 and through the drive sleeve 62. A drive column 621 is fixed on the inner peripheral wall of the drive sleeve 62. A guide groove 631 for the drive column 621 to be embedded is opened on the outer peripheral wall of the rotating rod 63 away from the switching ball 61. The guide groove 631 is spirally opened along the outer peripheral wall of the guide rod. When the signal metering module 2 is installed in the mounting slot 31 and continues to be pushed into the cavity 32, the drive column 621 drives the rotating rod 63 to rotate through the guide groove 631, so as to force the second switching channel 612 to rotate to communicate with the air intake section 124.

[0052] The implementation principle of Embodiment 3 of this application is as follows: Under normal conditions, after the signal metering module 2 is embedded in the mounting slot 31, the locking bolt 36 is rotated so that the locking bolt 36 extends into the limiting slide groove 21 (not fully tightened). Then, the signal metering module 2 is released, and the signal metering module 2 retracts under the action of the return spring 351, so that the locking bolt 36 abuts against the end of the limiting slide groove 21 near the regulator body 1. Then, the locking bolt 36 is tightened to complete the installation of the signal metering module 2. In this state, the air inlet section 124 faces the air outlet section 125, and the air inlet channel 14 introduces cooling gas into the air inlet section 124. The cooling gas passes through the air inlet section 124 and the air outlet section 125 in sequence, and is discharged outward through the air outlet channel 15.

[0053] When the equipment is used for a long time and the air supply channel 34 becomes blocked, loosen the locking bolt 36 (the locking bolt 36 is not disengaged from the limit slide groove 21), and then drive the signal metering module 2 to push into the cavity 32. This causes the opening and closing plate 35 to continue to slide towards the side closer to the signal metering module 2. The drive sleeve 62 on the opening and closing plate 35 pushes the inner wall of the guide groove 631 of the rotating rod 63 through the drive column 621, thereby forcing the switching ball 61 to rotate and causing the second switching channel 612 to rotate to connect with the air intake section 124. This allows the cooling gas in the heat dissipation channel 11 to directly enter the cavity 32, blowing out foreign objects in the air supply channel 34 and improving the overall ease of operation.

[0054] In addition, as the driving signal metering module 2 is pushed into the cavity 32, the gap between the sliding plate 41 and the opening and closing plate 35 becomes smaller, that is, the second flow port 413 becomes smaller, thereby increasing the flow velocity of the airflow through the second flow port 413, so that the airflow has enough power to blow the foreign objects in the supplementary airflow channel 34 outward, and improve the purging effect.

[0055] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
