Description

Technical Field

[0001] This utility model relates to the field of cultural relic cleaning technology, specifically an outdoor cultural relic cleaning tool based on the principle of balanced airflow. Background Technology

[0002] Outdoor ancient architectural relics (such as the roofs and eaves of traditional wooden buildings) have extremely high historical, cultural, and artistic value. However, due to their long-term exposure to the outdoor environment, their surfaces are easily covered by falling dust. The accumulation of dust not only affects the appearance of the relics but may also corrode the materials over time, reducing their preservation value. Therefore, it is necessary to clean the surfaces of the relics regularly.

[0003] In the prior art, utility model patent application number CN202422030630.5 discloses a cultural relic protection and cleaning device, including a cleaning brush sleeve and a cleaning brush handle. Two sets of guide blocks are fixedly connected to the outer wall of the cleaning brush handle, and two sets of sliding grooves are formed on the inner wall of the cleaning brush sleeve. The positions of the two sets of sliding grooves correspond to the positions of the two sets of guide blocks, and the shapes of the inner and outer walls fit together. A reset mechanism for driving the locking block to reset is installed in the limiting groove. This cultural relic protection and cleaning device, through its sliding connection design, allows the cleaning brush sleeve to be easily adjusted or replaced without replacing the entire cleaning brush device. The cooperation between the guide blocks and the sliding grooves, as well as the automatic reset mechanism of the locking block under the action of a spring, ensures the stable locking of the cleaning brush sleeve after replacement, avoiding potential loosening problems during operation. This maintains the staff's familiarity with the shape and weight of the cleaning brush handle, reducing the risk of unstable operation and damage to cultural relics due to unfamiliarity with new tools.

[0004] The cleaning device disclosed in the aforementioned patent wipes dust off the surface of cultural relics by directly contacting the surface with a cleaning brush. During operation, improper force control or abrasion of the surface of cultural relics by duster fibers can easily occur. This is especially true for complex and fragile parts of cultural relics such as brackets, where operational errors can easily lead to damage to the relics. Utility Model Content

[0005] The purpose of this invention is to provide an outdoor cultural relic cleaning tool based on the principle of balanced airflow, which aims to improve the problem that existing cleaning devices directly contact the surface of cultural relics to wipe away dust, and are prone to damage to the surface of cultural relics due to improper force control or duster fibers.

[0006] This utility model is implemented as follows: An outdoor cultural relic cleaning tool based on the principle of balanced airflow includes a vacuum cleaner body with a suction pipe, a fan body, and a controller. The fan body's outlet is connected to multiple blowing pipes, with the ends of the blowing pipes furthest from the fan body arranged around the suction pipe. The central axes of the multiple blowing pipe outlets converge on the central axis of the suction pipe. An infrared distance sensor is installed at the end of the suction pipe. The vacuum cleaner body, the fan body, and the infrared distance sensor are all electrically connected to the controller.

[0007] Preferably, the vacuum cleaner body includes a fixed plate, the vacuuming pipe is fixedly installed on the fixed plate, and the end of the blower pipe away from the blower body is arranged around the fixed plate.

[0008] Preferably, the fixing plate is provided with mounting holes along its circumference, each corresponding to a blower pipe, and the blower pipes are respectively installed in the corresponding mounting holes.

[0009] Preferably, the infrared distance sensor is fixedly mounted on a fixed plate, and the multiple air blowing pipes and the infrared distance sensor do not interfere with each other.

[0010] Preferably, the fan body includes a pipe connector, the air outlet of the fan body is connected to the pipe connector, and one end of the plurality of air blowing pipes near the fan body is connected to the pipe connector.

[0011] Preferably, the pipe tap is provided with multiple pipe connection ports, and the end of the blower pipe closest to the blower body is installed on the pipe connection port.

[0012] Preferably, the blower duct near the dust collection duct is made of metal, and the metal body of the blower duct and the dust collection duct are set at a certain angle.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a blower to drive multiple air ducts to blow up dust, which is then absorbed by the suction ducts of the vacuum cleaner body, without any physical contact with the surface of the cultural relic. At the same time, an infrared distance sensor monitors the distance between the suction ducts and the cultural relic in real time, effectively avoiding damage to fragile parts of the cultural relic such as brackets and painted decorations due to improper force control or tool wear, thus protecting the original shape and material of the cultural relic to the greatest extent.

[0014] 2. This utility model features multiple air-blowing ducts arranged around the suction duct at the end furthest from the blower body, with the central axes of the ducts at the air outlets converging on the central axis of the suction duct, forming a "conical airflow field." This precisely guides the blown dust to the suction port, reducing dust diffusion and ensuring effective dust removal while preventing airflow from impacting the artifact. This balanced airflow design allows for simultaneous and efficient dust removal, improving cleaning efficiency by over 40% compared to traditional tools, and is particularly suitable for the comprehensive cleaning of artifacts with complex structures.

[0017] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: Example 1 like Figures 1-4As shown, an outdoor cultural relic cleaning tool based on the principle of balanced airflow includes a vacuum cleaner body 1, a fan body 2, and a controller 4. The vacuum cleaner body 1 has a suction pipe 101. In addition to the suction pipe 101, the vacuum cleaner body 1 also includes a negative pressure generating component, a dust collection box, and an electrical control structure. The air outlet of the fan body 2 is simultaneously connected to multiple blowing pipes 3. The ends of the blowing pipes 3 away from the fan body 2 are arranged around the suction pipe 101. The central axes of the pipes at the air outlets of the multiple blowing pipes 3 converge on the central axis of the suction pipe 101. An infrared distance sensor 5 is installed at the end of the suction pipe 101. The vacuum cleaner body 1, the fan body 2, and the infrared distance sensor 5 are all electrically connected to the controller 4. The fixing plate 102 is made of stainless steel with a thickness of 5-8mm and is tightly connected to the outer wall of the suction pipe 101 by welding or bolting. Its outer diameter is 8-12cm larger than the pipe diameter of the suction pipe 101, providing stable support for the installation of the blowing pipes 3. The inner wall of the mounting hole 103 is equipped with a rubber anti-slip pad, which not only prevents the blower duct 3 from shifting due to airflow vibration during operation, but also buffers the collision between the duct and the fixed plate 102, reducing noise generation. The central axes of multiple metal duct sections eventually converge on the central axis of the suction duct 101 (the convergence point is located 1-2 cm in front of the suction port), forming a "conical airflow field" that precisely guides the blown dust to the suction port, maximizing dust adsorption efficiency and preventing dust from spreading to the surrounding area. The controller 4 is also connected to an audible and visual alarm. The detection range of the infrared distance sensor 5 covers an area of ​​1cm (safe distance) in front of the suction port. When the distance between the suction port and the surface of the cultural relic deviates from the safe range of 1cm-1.5cm, in addition to triggering the audible and visual alarm, the signal will also be transmitted to the controller 4 in real time. The controller 4 can automatically fine-tune the airflow intensity of the suction unit and the blowing unit according to the degree of deviation (e.g., when the distance is less than 1cm, the negative pressure intensity is temporarily reduced; when the distance is greater than 1.5cm, the positive pressure intensity is appropriately increased) until the operator adjusts the position of the tool to the safe range, further enhancing the protection of the cultural relic.

[0019] like Figures 1-4 As shown, the vacuum cleaner body 1 includes a fixed plate 102. The fixed plate 102 is fixedly mounted on the suction pipe 101, and the end of the blower pipe 3 away from the blower body 2 is arranged around the fixed plate 102. The fixed plate 102 has mounting holes 103 arranged sequentially along its circumference, corresponding one-to-one with each blower pipe 3. The blower pipes 3 are respectively installed in the corresponding mounting holes 103. An infrared distance sensor 5 is fixedly mounted on the fixed plate 102, and the multiple blower pipes 3 and the infrared distance sensor 5 do not interfere with each other.

[0020] like Figure 1 and Figures 4-6As shown, the fan body 2 includes a pipe connector 201. The air outlet of the fan body 2 is connected to the pipe connector 201, and multiple air ducts 3 are connected to the pipe connector 201 at their ends near the fan body 2. The pipe connector 201 is provided with multiple pipe connection ports 202, and the ends of the air ducts 3 near the fan body 2 are installed on the pipe connection ports 202. The air ducts 3 near the suction pipe 101 are made of metal, and the metal body of the air duct 3 and the suction pipe 101 are set at a certain angle. The pipe connector 201 is integrally injection molded from engineering plastic (such as ABS material), possessing good pressure resistance and corrosion resistance, and is suitable for the positive pressure working environment (2-5 kPa) of the fan body 2. The main inlet of the pipe tap 201 is connected to the air outlet of the blower body 2 via a thread, and the connection is wrapped with sealing tape to ensure no airflow leakage. The pipe connection ports 202 are evenly distributed around the tap, with the number of ports matching that of the blower pipes 3, and each pipe connection port 202 has the same inner diameter, ensuring uniform airflow distribution in each blower pipe 3 and preventing local air imbalance on the surface of the artifact due to uneven airflow. The blower pipes 3 adopt a "segmented material" design: the section near the blower body 2 (2 / 3 of the total length) is made of PVC plastic, which is lightweight and flexible, making it easy for operators to adjust the pipe direction according to the cleaning angle; the section near the suction pipe 101 (1 / 3 of the total length) is made of metal (such as aluminum alloy), which has good rigidity and can stably maintain the preset angle, ensuring accurate airflow direction.

[0021] Example 2 like Figures 1-4 As shown, an outdoor cultural relic cleaning tool based on the principle of balanced airflow includes a vacuum cleaner body 1, a fan body 2, and a controller 4. The vacuum cleaner body 1 has a suction pipe 101. The air outlet of the fan body 2 is connected to multiple blowing pipes 3. The end of the blowing pipe 3 away from the fan body 2 is arranged around the suction pipe 101. The central axes of the pipes at the air outlet positions of the multiple blowing pipes 3 converge on the central axis of the suction pipe 101. An infrared distance sensor 5 is provided at the end of the suction pipe 101. The vacuum cleaner body 1, the fan body 2, and the infrared distance sensor 5 are all electrically connected to the controller 4.

[0022] like Figures 1-4 As shown, the vacuum cleaner body 1 includes a fixed plate 102. The fixed plate 102 is fixedly mounted on the suction pipe 101, and the end of the blower pipe 3 away from the blower body 2 is arranged around the fixed plate 102. The fixed plate 102 has mounting holes 103 arranged sequentially along its circumference, corresponding one-to-one with each blower pipe 3. The blower pipes 3 are respectively installed in the corresponding mounting holes 103. An infrared distance sensor 5 is fixedly mounted on the fixed plate 102, and the multiple blower pipes 3 and the infrared distance sensor 5 do not interfere with each other.

[0023] like Figure 1 and Figures 4-6 As shown, the fan body 2 includes a pipe connector 201. The air outlet of the fan body 2 is connected to the pipe connector 201, and multiple air ducts 3 are connected to the pipe connector 201 at their ends near the fan body 2. The pipe connector 201 is provided with multiple pipe connection ports 202, and the ends of the air ducts 3 near the fan body 2 are installed on the pipe connection ports 202. The air ducts 3 near the suction pipe 101 are made of metal, and the metal body of the air duct 3 and the suction pipe 101 are set at a certain angle.
