Description

Technical Field

[0001] The invention belongs to the technical field of cleaning, and in particular relates to an equipment cleaning device. Background Art

[0002] Equipment dust removal and maintenance are essential issues during equipment use. Some equipment sits in warehouses for extended periods, leaving it covered in dust. Other equipment features cooling fans and heat dissipation holes, making them prone to dust accumulation. Since most equipment cannot be directly washed with water, dust removal and maintenance typically require disassembling the equipment casing and using a blower to remove the dust. This dust removal method presents several issues: The blowing process causes dust to fly, severely polluting the air and harming health. Furthermore, blowers only blow, not suck. For dust accumulation inside equipment, such as heat dissipation holes, the blower only causes the dust to fly chaotically within the area, making it difficult to blow it out, resulting in poor cleaning results. Summary of the Invention

[0007] Furthermore, there are multiple cleaning heads.

[0008] Furthermore, cleaning heads come in different sizes.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:

[0014] 1. The present invention uses a part of the through holes to spray high-pressure air to blow off the dust on the equipment to be cleaned, while the other part of the through holes generates a high negative pressure to suck the dust into the main body of the device. By blowing and sucking at the same time, the dust is blown off and sucked away, which solves the problem of using a blower to clean the dust on the equipment causing dust to fly around, seriously polluting the air and damaging human health. When removing dust from the internal areas of the equipment such as the heat dissipation holes, the high-speed air flow blows up the dust in the area and makes it fly around chaotically in the area. The suction holes suck the air from the area and also suck away the flying dust, solving the problem that the blower only blows but does not suck. For the dust accumulated inside the equipment, the blower can only make the dust fly around chaotically in the internal area, but it is difficult to blow it out, resulting in poor cleaning effect.

[0015] 2. The present invention distributes airflow and suction at intervals. By placing the cleaning head close to the equipment to be cleaned, blowing and sucking dust simultaneously, most of the dust that is blown away can be directly sucked away, preventing secondary contamination caused by dust attachment and preventing air pollution caused by flying dust. By switching the flow path, the distribution intervals of airflow and suction can be changed to accommodate equipment of different sizes and depths.

[0016] 3. The present invention blocks dust under the filter assembly and can be easily cleaned with water, which is convenient and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In the description of this embodiment, it should be noted that the terms "upper", "lower", "inner", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the inventive product is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0023] In the description of this embodiment, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "connected" and "connect" should be understood in a broad sense.

[0024] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0025] Reference Figures 1 to 4This embodiment discloses an equipment cleaning device, including a device body 100 and a cleaning head 200. The cleaning head 200 is provided with an air supply port 221 and an air extraction port 222, and is provided with a plurality of through holes 211, some of the through holes 211 are connected to the air supply port 221, and the remaining through holes 211 are connected to the air extraction port 222. The device body 100 includes an air outlet 111 and an air return port 112, the air outlet 111 and the air supply port 221 are connected by a hose, and the air return port 112 and the air extraction port 222 are connected by a hose. The device body 100 can eject high-pressure air from the air outlet 111 and inhale gas from the air return port 112.

[0026] During use, the device body 100 is opened, and the through hole 211 of the cleaning head 200 is directed toward the equipment to be cleaned. Part of the through holes 211 sprays high-pressure air to blow off the dust on the equipment to be cleaned, while the other part of the through holes 211 generates a high negative pressure to suck the dust into the device body 100. By blowing and sucking at the same time, the dust is blown off and sucked away, which solves the problem of using a blower to clean the dust of the equipment causing dust to fly, seriously pollute the air, and harm human health. When removing dust from the internal areas of the equipment such as the heat dissipation holes, the high-speed air flow blows up the dust in the area and makes it fly chaotically in the area. The through holes 211 for suction suck away the air from the area and also suck away the flying dust, solving the problem that the blower only blows but does not suck. For the dust accumulated inside the equipment, the blower can only make the dust fly chaotically in the internal area, but it is difficult to blow it out, resulting in poor cleaning effect.

[0027] The cleaning head 200 includes a cleaning portion 210 and a sliding portion 220. The front of the cleaning portion 210 is provided with multiple rows and columns of through holes 211, and the back is provided with multiple longitudinal grooves 212. Each longitudinal groove 212 connects all the through holes 211 in one or more columns. The distance between adjacent longitudinal grooves 212 is the same. At least four flow channels are provided in the sliding portion 220, including a first air supply channel 230, a first air exhaust channel 240, a second air supply channel 250, and a second air exhaust channel 260. The four flow channels are distributed at different heights of the sliding portion 220 and do not interfere with each other. The first air supply channel 230 is connected to the air supply port 221 and is provided with multiple outlets 223. The lateral distance between two adjacent outlets 223 is equal to twice the distance between adjacent longitudinal grooves 212. The first air exhaust channel 240 is connected to the air exhaust port 222 and is provided with multiple inlets 224. The lateral distance between two adjacent inlets 224 is equal to twice the distance between adjacent longitudinal grooves 212. The second air supply channel 250 is connected to the air supply port 221 and is provided with multiple groups of outlets 223. The lateral distance between two adjacent outlets 223 in each group of outlets 223 is equal to the distance between adjacent longitudinal slots 212. Assuming that the number of outlets 223 in each group of outlets 223 is n, the lateral distance between different groups of outlets 223 is n+1 times the distance between adjacent longitudinal slots 212. The second air exhaust channel 260 is connected to the air exhaust port 222 and is provided with multiple groups of inlets 224. The lateral distance between two adjacent inlets 224 in each group of inlets 224 is equal to the distance between adjacent longitudinal slots 212. Assuming that the number of outlets 223 in each group of inlets 224 is n, the lateral distance between different groups of inlets 224 is n+1 times the distance between adjacent longitudinal slots 212. The number of outlets 223 or inlets 224 in each of the four channels is equal, and is half the number of longitudinal slots 212. The outlet 223 of the first air supply channel 230 and the inlet 224 of the first air extraction channel 240 are arranged at intervals of adjacent longitudinal grooves 212 in the horizontal direction, and the outlet 223 of the second air supply channel 250 and the inlet 224 of the second air extraction channel 260 are interspersed with each other in the horizontal direction, with one outlet 223 or inlet 224 at every distance from the longitudinal groove 212. The sliding portion 220 slides relative to the cleaning portion 210 to switch the flow channel. When switching to the first air supply channel 230 and the first air extraction channel 240, refer to Figure 3 (For ease of understanding, the flow channels in the sliding portion 220 are projected downwards respectively), each inlet 224 and outlet 223 of the two flow channels are connected to a longitudinal groove 212, and at this time, the inlet 224 and outlet 223 of the second air supply channel 250 and the second air extraction channel 260 are both blocked by the cleaning portion 210; when switching to the second air supply channel 250 and the second air extraction channel 260, refer to Figure 4(For ease of understanding, the flow channels in the sliding portion 220 are projected downwards respectively), each inlet 224 and outlet 223 of the two flow channels are connected to a longitudinal groove body 212, and at this time, the inlet 224 and outlet 223 of the first air supply channel 230 and the first air extraction channel 240 are both blocked by the cleaning portion 210. Through the above technical solution, the air jet and the air suction are distributed at intervals, and the cleaning head 200 is close to the equipment to be cleaned. While blowing and sucking dust, most of the blown dust can be directly sucked away, avoiding secondary pollution caused by secondary attachment of dust and avoiding flying dust from polluting the air. By switching the flow channels, the distribution intervals of air blowing and air suction can be changed to adapt to equipment to be cleaned of different sizes and depths. The larger the distribution intervals of air blowing and air suction, the smaller the effect of air suction on air blowing, the farther the dust blowing distance, and the easier it is to clean dust in the hard-to-reach areas inside the equipment. However, sometimes the cross-section of the channel leading to the inside of the equipment is small. If the distribution intervals of air blowing and air suction are too large, they cannot act on the internal space of the equipment at the same time. Therefore, the distribution intervals of air blowing and air suction need to be adjusted. Furthermore, when processing smaller equipment surfaces, smaller air blowing and air suction distribution intervals mean less dust generation. Therefore, it is necessary to be able to adjust the air blowing and air suction distribution intervals to accommodate different operational requirements. It is foreseeable that those skilled in the art could, based on this embodiment, configure more flow channels to accommodate more diverse air blowing and air suction distribution intervals, which would still be within the scope of this embodiment.

[0028] Furthermore, multiple cleaning heads 200 of different sizes can be connected to the device body 100 and flexibly selected according to the operation needs, or multiple cleaning heads 200 can be operated simultaneously. Those skilled in the art can set valves to adjust the air flow of each cleaning head 200 according to actual needs, which will not be described in detail here.

[0029] The device body 100 includes a main housing 110, with an air outlet 111 located in the middle of the main housing 110 and an air return port 112 located in the upper portion of the main housing 110. A suction pump 113 is connected downstream of the air outlet 111, and the downstream portion of the suction pump 113 is connected to the cleaning head 200. A filter assembly 114 is disposed within the main housing 110 below the air outlet 111. The filter assembly 114 is horizontally mounted within the main housing 110. A sewage outlet 115 is disposed below the filter assembly 114 at the bottom of the main housing 110, along with a sewage valve 116. An intermediate baffle 117 is disposed within the main housing 110 between the air outlet 111 and the air return port 112. The air return port 112 is connected to the lower surface of the filter assembly 114 via a bypass channel 118, preventing direct communication between the air outlet 111 and the air return port 112, and allowing communication only through the filter assembly 114. A water spray assembly 119 is provided on the lower surface of the intermediate baffle 117. The water spray assembly 119 is connected to a water source and can spray water toward the filter assembly 114. During operation, the drain valve 116 is closed, the suction pump 113 provides high-pressure air to the downstream and negative pressure to the upstream, and the air carrying dust enters the main box 110 from the return air port 112, passes through the bypass channel 118, and is filtered by the filter assembly 114 and then sucked out by the suction pump 113. The dust is blocked on the lower surface of the filter assembly 114. After the operation is completed, the drain valve 116 is opened, and the water spray assembly 119 sprays water from above the filter assembly 114 to flush away the dust on the lower surface of the filter assembly 114 and discharge it from the drain port 115. Alternatively, the drain valve 116 can be closed periodically, while the water spray assembly 119 continues to spray water, filling the main housing 110 with water. This allows for comprehensive cleaning of the main housing 110. However, it is necessary to ensure that the air outlet 111 and the air return port 112 are closed. This can be accomplished by installing a valve, disconnecting the hose from the main body of the device, and taking measures to seal the air outlet 111 and the air return port 112. Furthermore, shaking can be employed to facilitate cleaning of the main housing 110. Furthermore, the water spray assembly 119 includes multiple water spray ports evenly distributed above the filter assembly 114.

[0030] The device body 100 also includes a water tank 120, which is disposed above the main housing 110. The bottom of the water tank 120 is connected to the water spray assembly 119 via a water spray pipe 130, which is provided with a water spray valve 140. The top of the water tank 120 is provided with a water inlet, which is mounted with a water inlet valve 121.

[0031] The above is only a detailed description of the preferred embodiments of the present invention, which is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
