Description

Technical Field

[0001] This invention relates to the field of UPS power supply technology, and in particular to a UPS power supply with automatic dust collection and removal. Background Technology

[0002] A UPS (Uninterruptible Power Supply) is a constant voltage and frequency power supply containing an energy storage device and primarily composed of an inverter. It is mainly used to provide uninterrupted power to single computers, computer network systems, or other power electronic equipment. People often carry UPSs when camping. The electronic components inside a UPS generate a lot of heat during operation, requiring cooling fans for dissipation. However, the outdoor environment is complex and dusty, and dust can enter the UPS through the cooling fans. This dust can reduce heat dissipation performance, corrode circuit boards and connectors, and even cause serious accidents. Therefore, most existing UPS power supplies have dust filters at their heat dissipation vents to reduce dust entry. However, after prolonged operation, dust can clog the gaps in the filters, significantly reducing heat dissipation efficiency. Therefore, there is a need for a UPS with automatic dust collection and removal capabilities to reduce the impact of accumulated dust at the heat dissipation vents on heat dissipation efficiency. Summary of the Invention

A motor base is provided below the heat sink, and the opening and closing motor is fixedly installed in the motor base. Multiple sets of opening and closing grilles are hinged at the fan base. The opening and closing motor is used to drive the opening and closing grilles to open or close the air inlet.

[0008] Furthermore, the power supply body includes a power supply component, a power supply bracket, a front panel, a back panel, and a housing. A dust removal bracket is installed on the power supply bracket, which is installed inside the housing. The power supply bracket divides the housing into a power supply chamber and an exhaust chamber. The power supply chamber is used to install the power supply component. The fan mount is connected to the power supply chamber, and the exhaust chamber is connected to the exhaust chamber. The front panel is installed at the front end of the housing, and the back panel is detachably installed at the rear end of the housing. The back panel has openings corresponding to the dust filter seat and the dust collection chamber, respectively. A detachable baffle is installed at the opening.

[0013] The UPS power supply with automatic dust collection and removal provided by this invention, compared with the prior art, has a significant reduction in dust in the airflow entering the power supply chamber due to the filtration of the dust filter component, thus reducing the interference of dust on the internal electronic components of the UPS power supply. During the idle period of the UPS power supply, the user can start the air intake fan to adsorb the dust intercepted in the dust filter component into the dust collection block. By reducing the amount of dust accumulation in the dust filter component, the airflow of the cooling fan into the power supply body is increased, thus avoiding excessive dust accumulation that affects the heat dissipation efficiency.

[0036] The present invention will be described in detail below with reference to specific embodiments.

[0037] In this invention, unless otherwise explicitly specified and limited, terms such as "set in," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Directional terms appearing in this invention are used to better describe the characteristics of the features and the relationships between them. It should be understood that when the orientation of this invention changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute spatial limitation on the characteristics of the features and the relationships between them, but only a relative limitation.

[0038] like Figures 1 to 18 As shown, the present invention provides an automatic dust collection and removal UPS power supply, including a power supply body 1. The power supply body 1 is provided with a dust collection and removal mechanism 2. The dust collection and removal mechanism 2 includes a dust collection support 20, a dust filter assembly 22, a dust collection assembly 23, and a cooling fan 24. The dust collection support 20 is installed in the power supply body 1. The dust collection support 20 includes a fan seat 205, a dust collection seat, and a dust filter seat 200. The dust filter seat 200 is used to install the dust filter assembly 22. The fan seat 205 is provided on the side of the dust filter seat 200. The fan seat 205 is used to install the cooling fan 24. The fan seat 205 is also provided with an air inlet corresponding to the cooling fan 24. The dust collection seat is provided at the bottom of the dust filter seat 200. The dust collection seat is used to install the dust collection assembly 23.

[0039] The dust collection assembly 23 includes a dust collection block 230, an air intake fan 231, and a pop-up part 204. The dust collection seat includes a dust collection chamber 201 and an air extraction chamber 202. The dust collection chamber 201 is located at the bottom of the dust collection seat 200, and the air extraction chamber 202 is located at the bottom of the dust collection chamber 201. The dust collection seat 200 is connected to the dust collection chamber 201 and the air extraction chamber 202 in sequence. The dust collection chamber 201 is used to install the dust collection block 230. The air intake fan 231 and the pop-up part 204 are both installed in the air extraction chamber 202. A limiting guide rail 203 is provided inside the air extraction chamber 202. A limiting slide groove 232 is provided on the air intake fan 231. The limiting slide groove 232 can slide in the limiting guide rail 203. The pop-up part 204 is used to pop the air intake fan 231 out of the air extraction chamber 202.

[0040] With the above design, when it is necessary to dissipate heat for the electronic components inside the UPS power supply, the cooling fan 24 will draw air from the outside into the power supply body 1, and the dust collection component 23 will intercept most of the dust inside. Under the action of gravity, some of the dust will fall into the dust collection block 230. When the UPS power supply is idle, the user only needs to start the automatic dust removal program, and the intake fan 231 will actively absorb the intercepted dust into the dust collection block 230, reducing the dust content in the dust filter component 22, and ensuring that when heat dissipation is needed, the dust filter component 22 will not reduce the air intake due to excessive dust accumulation, thus affecting the heat dissipation efficiency.

[0041] Since the dust collection chamber 201 does not participate in the airflow direction during heat dissipation, the dust collection block 230 can collect more dust without worrying that the accumulated dust will affect the heat dissipation efficiency, thereby reducing the frequency of cleaning by the user.

[0042] In this embodiment, the dust collection block 230 is made of multiple segments of sponge with different densities.

[0043] In this embodiment, the dust filter assembly 22 includes a dust filter frame 220, a front dust filter 221, a flow-retarding section, a rear dust filter 223, and a dust filter block 224. The dust filter frame 220 is detachably installed in the dust filter base 200. The dust filter frame 220 is sequentially installed with the detachable front dust filter 221, the rear dust filter 223, and the dust filter block 224. The dust filter block 224 is located at the end of the dust filter frame 220 near the cooling fan 24. The flow-retarding section is located between the front dust filter 221 and the rear dust filter 223. The flow-retarding section contains multiple staggered flow-retarding plates 222. The bottom of the flow-retarding section and the dust filter frame 220 at the bottom of the rear dust filter 223 are provided with through grooves 226 that connect to the dust collection base. The end of the dust filter frame 220 away from the cooling fan 24 is provided with a storage handle 225.

[0044] In this embodiment, the front-end dust filter 221 is made of a filter with a smaller mesh size, the end-end dust filter 223 is made of a filter with a larger mesh size, and the dust filter block 224 includes an activated carbon layer, a sponge layer, and a dehumidification layer.

[0045] Through the above design scheme, the front-end dust filter 221 is used to block larger impurity particles from entering the dust filter frame 220. The airflow passing through the front-end dust filter 221 will collide with the staggered baffles 222. The staggered baffles 222 will reduce the airflow velocity, causing the dust in the airflow to fall automatically into the dust collection block 230 below under the action of gravity. The dust collection block 230 will intercept and capture the dust. The smaller dust particles in the airflow will be further intercepted by the end dust filter 223, further reducing the dust content in the airflow. The final dust filter block 224 can intercept moisture and other smaller impurities in the air, protecting the electronic components inside the power supply body 1.

[0046] In this embodiment, an opening and closing assembly 21 is provided at the fan base 205. The opening and closing assembly 21 includes an opening and closing motor 210 and an opening and closing grid plate 211. A motor base is provided below the fan base 205. The opening and closing motor 210 is fixedly installed in the motor base. Multiple sets of opening and closing grid plates 211 are hinged at the fan base 205. The opening and closing motor 210 is used to drive the opening and closing grid plates 211 to open or close the air inlet.

[0047] With the above design scheme, when performing heat dissipation, the opening and closing motor 210 drives the opening and closing grid plate 211 to keep the air inlet in the open state, ensuring that the cooling fan 24 can guide the airflow into the power supply body 1 normally. When dust removal is required, the opening and closing motor 210 drives the opening and closing grid plate 211 to close, preventing the external airflow from flowing back from the air outlet 111 into the power supply body 1, so that the external airflow will directly change its flow direction after entering the dust filter assembly 22 and pass through the dust collection chamber 201 for dust collection and removal.

[0048] In this embodiment, the power supply body 1 includes a power supply component 14, a power supply bracket 13, a front plate 11, a back plate 12, and a cover 10. A dust removal support 20 is installed on the power supply bracket 13, which is installed in the cover 10. The power supply bracket 13 divides the cover 10 into a power supply chamber 16 and an exhaust chamber 15. The power supply chamber 16 is used to install the power supply component 14. A fan mount 205 is connected to the power supply chamber 16, and an exhaust chamber 202 is connected to the exhaust chamber 15. The front plate 11 is installed at the front end of the cover 10, and the back plate 12 is detachably installed at the rear end of the cover 10. The back plate 12 has openings corresponding to the dust filter seat 200 and the dust collection chamber 201, respectively. A detachable barrier net 120 is installed at the opening, and the suction fan 231 is detachably installed on the back plate 12 by screws.

[0049] Through the above design scheme, the barrier net 120 at the opening can ensure that the dust filter assembly 22 and the dust collection block 230 are locked in the dust collection bracket. When it is necessary to clean the dust filter assembly 22 or replace the dust collection block 230, the user only needs to remove the barrier net 120 to take out the dust collection block 230 or the dust filter assembly 22. Since the dust collection block 230 is made of sponge, the user can directly pinch the dust collection block 230 and pull it out from the dust collection chamber 201. When it is necessary to disassemble the dust filter assembly 22, the user only needs to turn the storage handle 225 on the dust filter rack 220, and then pull the dust filter rack 220 directly out of the dust filter seat 200 through the storage handle 225. When installing, the user only needs to push the dust filter rack 220 into the dust filter seat 200.

[0050] In this embodiment, a vent 130 is provided on the power supply bracket 13, which is used to connect the power supply chamber 16 and the exhaust chamber 15. A one-way air guide shroud 131 is provided at the vent 130, and an inclined groove 132 is provided in the one-way air guide shroud 131. An air outlet 111 is provided on the front plate 11, which is connected to the exhaust chamber 15.

[0051] With the above design, during normal heat dissipation, the air entering the power supply chamber 16 will flow to the exhaust chamber 15 through the vent 130, and then be blown out from the exhaust outlet 111 connected to the exhaust chamber 15. The one-way guide shroud 131 at the vent 130 can guide the flow of air in the power supply chamber 16. During dust removal, the suction fan 231 guides the airflow from the dust filter assembly 22 into the exhaust chamber 15, and then from the exhaust chamber 15 to the exhaust outlet 111. Under the action of the inclined groove 132, the airflow in the exhaust chamber 15 will cause the inclined groove 132 to close, preventing exhaust gas from entering the power supply chamber 16.

[0052] In this embodiment, the power supply assembly 14 includes a power battery 140, a main control board 142, an inverter 143, and a main control screen 141. The power battery 140, the main control board 142, the inverter 143, and the main control screen 141 are all mounted on the power supply bracket 13, and the main control board 142 is electrically connected to the cooling fan 24, the power battery 140, the inverter 143, and the main control screen 141, respectively. A power socket 110 is provided on the front panel 11, and a charging port 121 is provided on the back panel 12. Both the power socket 110 and the charging port 121 are electrically connected to the main control board 142.

[0053] Since the power supply component 14 is existing technology and is not an improvement of this embodiment, it is not described in detail in this embodiment.

[0054] In this embodiment, power contacts are provided on the limiting slide rail and the limiting slide groove 232. When the suction fan 231 is inserted into the suction chamber 202, the power contacts in the limiting slide rail and the limiting slide groove 232 abut against each other, and the main control board 142 is electrically connected to the suction fan 231 through the power contacts.

[0055] With the above design, after long-term use, a large amount of dust will inevitably accumulate on the suction fan 231. This dust will inevitably affect the working efficiency of the suction fan 231. Therefore, it is necessary to remove the suction fan 231 for cleaning when necessary. When cleaning the suction fan 231 is required, the user only needs to loosen the screws connecting the suction fan 231 to the back plate 12. Under the action of the pop-out part 204, the suction fan 231 will be popped out of the suction chamber 202, making it convenient for the user to remove the suction fan. The fan 231 is used for cleaning. When installing the suction fan 231, the user only needs to align the limiting slide groove 232 of the suction fan 231 with the limiting guide rail 203 and push it into the suction chamber 202. While pressing against the suction fan 231, tighten the screws to fix the suction fan 231. The limiting guide rail 203 and the limiting slide groove 232 can ensure that the suction fan 231 is electrically connected to the main control board 142 while performing positioning and assembly, ensuring that the suction fan 231 can be controlled by the main control board 142.

[0056] In this embodiment, the bottom of the cover is provided with anti-slip pads, and the top of the cover is provided with a handle.

[0057] The UPS power supply with automatic dust collection and removal provided by this invention, compared with the prior art, has a significant reduction in dust in the airflow entering the power chamber 16 due to the filtration of the dust filter assembly. When the UPS power supply is idle, the opening and closing motor will drive the opening and closing grid to close the air inlet, and at the same time the suction fan will start to adsorb the dust filtered by the slow flow section and the end dust filter into the dust collection block, reducing the amount of dust accumulated in the dust filter assembly and avoiding excessive dust accumulation that affects heat dissipation efficiency.

[0058] Where there is no conflict, the above embodiments and features can be combined with each other.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
