Description
Technical Field
[0001] This utility model relates to the field of inverter power supply technology, specifically to an efficient dustproof and heat dissipation composite structure for the inner cavity partition of an inverter power supply. Background Technology
[0002] An inverter power supply generally refers to an inverter, which is a converter that transforms direct current (DC) power into constant frequency and voltage (CFD) or frequency and voltage regulated alternating current (AC). It consists of an inverter bridge, control logic, and filter circuits. It is widely used in air conditioners, home theaters, electric grinders, power tools, sewing machines, DVDs, VCDs, computers, televisions, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting, etc.
[0003] Inverters generate a significant amount of heat during operation, necessitating the installation of internal cooling devices to dissipate heat and ensure proper functioning. Existing inverter cooling systems rely on fans to circulate airflow, expelling hot air and introducing cool air. However, this rapid airflow draws dust and other impurities from the outside air, causing them to accumulate on the internal filters. Prolonged exposure to dust can lead to severe clogging, reducing airflow speed and overall cooling efficiency.
[0004] The existing inverters lack a structure for quick filter cleaning in their internal cavity, which means that operators need to disassemble the entire inverter casing to clean the filter. This is very cumbersome, and frequent disassembly and reassembly can affect the overall stability of the inverter and reduce its service life.
[0005] To address this issue, a high-efficiency dustproof and heat-dissipating composite structure for the inner cavity of an inverter power supply is proposed. Utility Model Content
[0006] The purpose of this utility model is to provide a high-efficiency dustproof and heat-dissipating composite structure for the inner cavity of an inverter power supply, so as to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: A high-efficiency dustproof and heat-dissipating composite structure for the inner cavity of an inverter power supply, including a base and a limiting partition.

A second slider is welded to each side of the control rod body. The second slider is slidably installed inside the limiting groove. A dust discharge port is provided at the bottom of the base. A baffle assembly is installed inside the dust discharge port via a rotating shaft.
[0007] Preferably, a first slider is welded to each side of the slide plate, and the first slider extends into the mounting groove and is slidably sleeved on the outside of the support slide rod.

[0014] Compared with the prior art, this utility model provides a high-efficiency dustproof and heat dissipation composite structure for the inner cavity of an inverter power supply, which has the following beneficial effects:
[0015] By pushing the push rod, the second slider slides along the opening direction of the limiting slide groove, causing the slide plate to slide downwards along the installation direction of the support slide rod. During the downward sliding of the slide plate, the brush head will rub against one side of the filter screen, thereby scraping off the dust adsorbed on one side of the filter screen. The scraped-off dust can be discharged into the interior of the outer cover through the opened dust discharge port.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example 1: A limiting partition 2 is welded to the top of the base 1. A filter screen 3 is installed on each side of the limiting partition 2. A cooling fan 4 is installed on each side of the top of the base 1. An outer cover 6 is installed on the top of the base 1. Two mounting grooves 5 are opened on each side of the inside of the outer cover 6. A support slide rod 11 is fixed inside the mounting groove 5. A first spring 13 is sleeved on the outside of the support slide rod 11. Two cleaning components 7 are slidably installed inside the outer cover 6. The cleaning component 7 includes a sliding plate 701. A support sleeve 702 is fixed on one side of the sliding plate 701. A control rod assembly 10 is fitted on the outer side of 02. The control rod assembly 10 includes a control rod body 1001. A push rod 1003 is welded to one end of the control rod body 1001. A sliding groove 14 is opened on the top of the outer cover 6. A limiting sliding groove 1401 is opened on both sides of the sliding groove 14. A second slider 1002 is welded to both sides of the control rod body 1001. The second slider 1002 is slidably installed inside the limiting sliding groove 1401. A ash discharge port 8 is opened at the bottom of the base 1. A baffle assembly 9 is installed inside the ash discharge port 8 through a rotating shaft.
[0026] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the outer cover 6 is installed on top of the base 1, thus placing the limiting partition 2 inside the outer cover 6. The inverter power supply circuit board can be installed inside the limiting partition 2. After the base 1 and the outer cover 6 are connected and fixed, the top of the limiting partition 2 will abut against the top of the inner part of the outer cover 6, thus protecting the circuit board inside the limiting partition 2. Since a filter screen 3 is installed on each side of the limiting partition 2, the two filters 3 can filter the dust in the air entering the outer cover 6, preventing contamination of the circuit board installed inside the limiting partition 2. After the base 1 and the outer cover 6 are installed, the brush head 704 will contact one side of the filter screen 3. When the filter screen 3 is clogged due to the accumulation of a large amount of dust on its surface after long-term use, the baffle assembly 9 installed inside the ash discharge port 8 can be opened to open the ash discharge port 8. Then, by pushing the push rod 1003, the second slider 1002 moves along the opening direction of the limiting slide groove 1401. The slide mechanism works as follows: Since the bottom of the push rod 1003 is fixed with the control rod body 1001, and one end of the control rod body 1001 is sleeved on the outside of the support sleeve 702, when the push rod 1003 is pushed, the sliding plate 701 is driven to slide downward along the installation direction of the support slide rod 11. During the downward sliding of the sliding plate 701, the brush head 704 will rub against one side of the filter screen 3, thereby scraping off the dust adsorbed on one side of the filter screen 3. The scraped dust can be discharged into the interior of the outer cover 6 through the opened dust discharge port 8. During the downward sliding of the sliding plate 701, the first spring 13 sleeved on the outside of the support slide rod 11 will be compressed. When the push rod 1003 is released, the sliding plate 701 can be automatically pushed upward by the rebound force generated by the compressed filter screen 3. This structure can quickly clean the filter screen 3 inside the inverter without removing the inverter, thus improving the heat dissipation efficiency inside the inverter.
[0027] Example 2: Heat dissipation vents 103 are respectively provided on both sides of the outer cover 6, and the heat dissipation vents 103 are connected to the interior of the outer cover 6. Positioning blocks 101 are integrally formed on both sides of the top of the base 1, and the positioning blocks 101 have first threaded holes 102 inside. Two second threaded holes 601 are respectively provided on both sides of the outer cover 6, and the second threaded holes 601 cooperate with the first threaded holes 102. A fixing hole 801 is provided on one side inside the ash discharge port 8. The baffle assembly 9 includes a baffle body 901, and the baffle body 901 is installed inside the cooling fan 4 via a rotating shaft. A receiving groove 9 is provided inside the baffle body 901. 02. A first groove 903 is provided on each side of the inside of the storage groove 902, and a limiting slide post 904 is fixed inside the two first grooves 903 respectively. A limiting rod 905 is slidably installed inside the storage groove 902. The two sides of the limiting rod 905 extend into the inside of the first groove 903 and are slidably installed on the outside of the limiting slide post 904. A second spring 907 is sleeved on the outside of the limiting slide post 904. A control block 906 is fixed on one side of the limiting rod 905, and the control block 906 extends out of the inside of the storage groove 902. One end of the limiting rod 905 extends out of the inside of the storage groove 902.
[0028] Specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, the heat dissipation vents 103 on both sides of the outer cover 6 allow cold air to enter the interior of the outer cover 6, while the hot gas inside the outer cover 6 is discharged. When installing the base 1 and the outer cover 6, the fixing block 101 fixed on the top of the base 1 is inserted into the interior of the outer cover 6, and the first threaded hole 102 is aligned with the second threaded hole 601 before being fixed with bolts. The control block 906 can control the limiting rod 905 and retract the limiting rod 905 into the receiving groove 902, so that the limiting rod... One end of 905 is pulled out from inside the fixing hole 801, and then the baffle body 901 can be flipped open, so that the dust falls out from inside the inverter through the ash discharge port 8. When the control limit plug 905 is stored in the storage slide 902, the two sides of the limit plug 905 will slide along the installation direction of the limit slide post 904, thereby compressing the second spring 907. Through the rebound force of the second spring 907, one end of the limit plug 905 can be ejected back into the storage slide 902 and inserted into the fixing hole 801.
[0029] Working principle: During use, when the filter screen 3 becomes clogged due to long-term use and the surface adsorbs a large amount of dust, the baffle assembly 9 installed inside the ash discharge port 8 can be opened to expand the ash discharge port 8. Then, by pushing the push rod 1003, the second slider 1002 slides along the opening direction of the limiting slide groove 1401. Since the bottom of the push rod 1003 is fixed with the control rod body 1001, and one end of the control rod body 1001 is sleeved on the outside of the support sleeve 702, when the push rod 1003 is pushed, the sliding plate 701 is driven to slide downward along the installation direction of the support slide rod 11. During the sliding process, the brush head 704 will rub against one side of the filter screen 3, thereby scraping off the dust adsorbed on one side of the filter screen 3. The scraped dust can be discharged into the interior of the outer cover 6 through the opened dust discharge port 8. When the sliding plate 701 slides down, it will compress the first spring 13 sleeved on the outside of the support slide rod 11. When the push rod 1003 is released, the sliding plate 701 can be automatically pushed upward by the rebound force generated by the compressed filter screen 3. Through this structure, the filter screen 3 inside the inverter can be cleaned quickly without removing the inverter, thus improving the heat dissipation efficiency inside the inverter.
