Description

[Technical Field]

[0001] This application belongs to the field of road construction equipment technology, specifically relating to a multi-angle air purification device for road construction. [Background Technology]

[0002] At road construction sites, air quality is a key environmental factor determining the health of personnel. Because road construction may involve the release of large amounts of dust, volatile organic compounds, and other pollutants, air purifiers are currently used at road construction sites to improve air quality.

[0003] Traditional air purifiers used on road construction sites are often installed in a fixed manner. Moreover, air purifiers used for road construction are relatively large and need to be placed in a fixed location. However, due to the complexity and variability of road construction sites, on-site workers need to frequently move and adjust their working positions during the road construction process. This means that the exhaust port of the air purifier cannot be aligned with the workers' working positions, making it difficult to effectively provide clean air for on-site workers. [Summary of the Invention]

[0004] To address the problem that existing air purifiers have a single exhaust port angle and cannot be easily adjusted, this application provides a multi-angle air purification device for road construction.

[0005] This application is achieved through the following technical solution:

[0006] A multi-angle air purification device for road construction includes a filter device, a housing base, a housing assembly detachably connected to the housing base, and an air inlet on the housing assembly. The filter device includes a filter screen assembly on the air inlet and an exhaust assembly located between the housing base and the housing assembly and connected to the filter screen assembly via a pipe. The exhaust assembly is used to discharge gas passing through the filter screen assembly. The bottom of the housing assembly is provided with a first limiting groove that surrounds the bottom edge of the housing assembly, and the top of the housing base is provided with a second limiting groove corresponding to the first limiting groove. The first limiting groove and the second limiting groove cooperate to form a channel for the exhaust assembly to move and restrict it from leaving the first limiting groove and the second limiting groove.

[0007] As described above, a multi-angle air purification device for road construction includes a filter assembly comprising a fixed cup, a large-aperture filter, and a small-aperture filter. The top of the fixed cup is provided with a first flange for placing the large-aperture filter, and the bottom of the fixed cup is provided with a second flange for placing the small-aperture filter. Both the top and bottom of the fixed cup are provided with openings.

[0008] The multi-angle air purification device for road construction described above further includes a first buckle disposed above the first flange for holding the large-aperture filter on the first flange, and a second buckle disposed above the second flange for holding the small-aperture filter on the second flange.

[0009] The multi-angle air purification device for road construction described above also includes a handle hinged to the top of the bowl / cup, and the top of the housing assembly has a groove for the handle to be inserted.

[0010] The multi-angle air purification device for road construction described above also includes a water storage tank located inside the base of the housing and connected to the exhaust assembly via a pipe.

[0011] The multi-angle air purification device for road construction described above also includes a light source assembly, which includes LED light groups respectively disposed on the four sides of the housing assembly, and a battery disposed in the base of the housing and electrically connected to the LED light groups.

[0012] As described above, a multi-angle air purification device for road construction includes a first conductive plate connected to each of the LED light groups within the housing assembly, with insulating rubber between adjacent first conductive plates. A second conductive plate corresponding to the first conductive plate is provided within the base of the housing, with insulating rubber between adjacent second conductive plates. The exhaust assembly abuts against the first and second conductive plates, and the exhaust assembly is made of conductive material.

[0013] The multi-angle air purification device for road construction described above also includes a handle hinged to the exhaust assembly, the handle being made of insulating material.

[0014] As described above, in a multi-angle air purification device for road construction, when the exhaust assembly is moved to any side of the housing assembly, the first conductive plate and the second conductive plate on the side where the exhaust assembly is located are connected to each other, so that the LED light group on the side where the exhaust assembly is located can work.

[0015] Compared with the prior art, this application has the following advantages:

[0016] This application discloses a multi-angle air purification device for road construction. Air is drawn in through the air inlet, filtered by the filter device, and then discharged from the exhaust assembly through the pipe. By connecting the base of the housing to the shell assembly, the first limiting groove on the shell assembly and the second limiting groove on the base of the housing cooperate to form a channel for the movement of the exhaust assembly, enabling the exhaust assembly to be adjusted in 360 degrees. This makes the operation more convenient and faster, and improves work efficiency. [Attached Image Description]

Detailed Implementation Methods

[0027] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0028] Please see Figures 1 to 9A multi-angle air purification device for road construction includes a filter device 1, a housing base 2, a housing assembly 3 detachably connected to the housing base 2, and an air inlet 4 disposed on the housing assembly 3. The filter device 1 includes a filter screen assembly 11 disposed on the air inlet 4, and an exhaust assembly 12 disposed between the housing base 2 and the housing assembly 3 and connected to the filter screen assembly 11 via a pipe. The exhaust assembly 12 is used to exhaust gas passing through the filter screen assembly 11. The bottom of the housing assembly 3 is provided with a first limiting groove 5 arranged around the bottom edge of the housing assembly 3, and the top of the housing base 2 is provided with a second limiting groove 6 corresponding to the first limiting groove 5. The first limiting groove 5 and the second limiting groove 6 cooperate to form a channel for the exhaust assembly 12 to move and restrict it from leaving the first limiting groove 5 and the second limiting groove 6.

[0029] This application discloses a multi-angle air purification device for road construction. Air is drawn in through the air inlet, filtered by the filter device, and then discharged from the exhaust assembly through the pipe. By connecting the base of the housing to the shell assembly, the first limiting groove on the shell assembly and the second limiting groove on the base of the housing cooperate to form a channel for the movement of the exhaust assembly, enabling the exhaust assembly to be adjusted in 360 degrees. This makes the operation more convenient and faster, and improves work efficiency.

[0030] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the filter assembly 11 includes a fixed bowl 111, a large-pore filter 112, and a small-pore filter 113. The fixed bowl 111 has a first flange 1111 at its top for placing the large-pore filter 112, and a second flange 1112 at its bottom for placing the small-pore filter 113. The fixed bowl 111 has openings at both its top and bottom.

[0031] In this embodiment, the top of the fixed bowl cup is provided with a first flange for placing a large-pore filter screen, and the bottom is provided with a second flange for placing a small-pore filter screen. Both the top and bottom have openings. This structure helps to simplify the installation and replacement process of the filter screen. By placing filter screens with different pore sizes, it can adapt to the filtration needs of different particle sizes. If only a small-pore filter screen is used, the service life of the small-pore filter screen will be reduced when filtering large dust particles, and the efficiency cannot be maximized. Large particles in the air first pass through the large-pore filter screen, and the remaining small particles are then filtered by the small-pore filter screen. This design allows for more efficient filtration, while also facilitating maintenance and cleaning, and improving the service life and performance of the filter screen.

[0032] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, it also includes a first buckle 1113 disposed above the first flange 1111 for holding the large-aperture filter 112 on the first flange 1111, and a second buckle 1114 disposed above the second flange 1112 for holding the small-aperture filter 113 on the second flange 1112.

[0033] In this embodiment, the design further enhances the stability and reliability of the filter assembly, ensuring that the filter will not accidentally fall off or shift during operation, thereby improving filtration efficiency and equipment reliability. At the same time, this snap-fit ​​structure facilitates filter replacement and maintenance, making operation simpler and more efficient.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, it also includes a handle 114 hinged to the top of the bowl 111, and the top of the housing assembly 6 is provided with a groove 61 for the handle 114 to be inserted.

[0035] In this embodiment, the user can easily lift the fixed bowl using the handle to more easily replace, clean, or maintain the filter. The groove design ensures that the handle can be embedded in it when not in use, preventing the handle from interfering with the normal operation or storage of the device, providing convenience and compactness, and enhancing the user experience and portability of the device.

[0036] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, it also includes a water storage tank disposed within the base 2 of the housing and connected to the exhaust assembly 12 via a pipe.

[0037] In this embodiment, the water storage tank can store a certain amount of water. When the exhaust component discharges the filtered gas, the water in the water storage tank will also be discharged at the same time, increasing the humidity in the gas and preventing the drawings from being blown up during construction and affecting visibility.

[0038] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a light source assembly 7, which includes LED light groups 71 respectively disposed on the four sides of the housing assembly 6, and a battery disposed in the housing base 2 and electrically connected to the LED light groups 71.

[0039] In this embodiment, the device is provided with a lighting function, which provides sufficient lighting during use, making it easier for staff to observe and operate. At the same time, the battery serves as an independent power source, so the device does not need to rely on an external power source, increasing its portability and flexibility.

[0040] Furthermore, as a preferred embodiment of this solution and not a limitation, the housing assembly 3 is provided with a first conductive plate 31 that is connected to the LED light group 71 in a one-to-one manner, and an insulating rubber 32 is provided between adjacent first conductive plates 31. The housing base 2 is provided with a second conductive plate 33 that is provided corresponding to the first conductive plate 31, and an insulating rubber 32 is provided between adjacent second conductive plates 33. The exhaust assembly 12 abuts against the first conductive plate 31 and the second conductive plate 33, and the exhaust assembly 12 is made of conductive material.

[0041] In this embodiment, when construction is carried out at night, visibility is low, and air purifiers are usually placed next to the work area. With this design, when the exhaust assembly is facing the side where the workers are, the first and second conductive plates on one side of the exhaust assembly are connected through the exhaust assembly, and the LED lights on the current side are lit. Since there is insulating rubber between the adjacent first and second conductive plates, the current will not be transmitted to the first and second conductive plates on the adjacent side, so that only the LED lights on the current side are lit, making it easier for passing vehicles to spot the workers on that side, improving visibility and enhancing safety. The conductive material is a metal material, such as silver, copper, gold, or aluminum.

[0042] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a grip 8 hinged to the exhaust assembly 12, the grip 8 being made of insulating material.

[0043] In this embodiment, the hinged design of the grip allows users to easily adjust the position or angle of the exhaust assembly to meet different usage needs. Simultaneously, the grip is made of insulating material, effectively blocking current conduction and protecting users from potential electric shock or static electricity hazards, ensuring user safety and comfort when operating the device. The insulating material includes rubber, cotton yarn, and resin.

[0044] Furthermore, as a preferred embodiment of this solution and not a limitation, when the exhaust assembly 12 is moved to any side of the housing assembly 3, the first conductive plate 31 and the second conductive plate 32 on the side where the exhaust assembly 12 is located are connected to each other, so that the LED light group 71 on the side where the exhaust assembly 12 is located is activated.

[0045] The working principle of this embodiment is as follows:

[0046] This application discloses a multi-angle air purification device for road construction. Air is drawn in through the air inlet, filtered by the filter device, and then discharged from the exhaust assembly through the pipe. By connecting the base of the housing to the shell assembly, the first limiting groove on the shell assembly and the second limiting groove on the base of the housing cooperate to form a channel for the movement of the exhaust assembly, enabling the exhaust assembly to be adjusted in 360 degrees. This makes the operation more convenient and faster, and improves work efficiency.
