Technical Field
[0001] This utility model relates to the field of waste collection technology, and in particular to a vacuum suction box. Background Technology
[0002] Waste refers to solid, semi-solid, liquid, and gaseous items or substances placed in containers that are generated during industrial production activities and have lost their original value or have been discarded or abandoned even if they have not lost their value. Waste that has no value to use itself needs to be collected with special tools.
[0003] Currently, vacuum suction boxes are used to collect solid waste. Most existing vacuum suction boxes consist of a box body and a sponge filter. The sponge filter only has one air passage surface. Once the waste fills the air passage surface of the sponge filter, the suction power will decrease. Therefore, a vacuum suction box that can ensure a long-lasting and stable suction power is needed. Utility Model Content

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0021] Please see Figs. 1-4 In this embodiment of the present invention, a vacuum suction box includes a box body 1, a filter frame 2, and a negative pressure generating device 3. The box body 1 is provided with a partition 11 to divide the internal space of the box body 1 into a first cavity 13 and a second cavity 14. An air inlet 15 communicating with the first cavity 13 is opened on the top surface of the box body 1. A vent 16 is opened in the middle of the partition 11. An air outlet 17 communicating with the second cavity 14 is opened on the bottom and side surfaces of the box body 1. The filter frame 2 is disposed in the first cavity 13. The filter frame 2 is composed of a base plate 21 and a peripheral plate 22 connected to the outer periphery of the base plate 21. There is a gap between the base plate 21 and the partition 11. Filter holes 23 are opened on both the base plate 21 and the peripheral plate 22. The negative pressure generating device 3 is disposed on the bottom surface of the partition 11. The air inlet of the negative pressure generating device 3 is connected to the vent 16, and the air outlet of the negative pressure generating device 3 is connected to the second cavity 14.
[0022] During use, the negative pressure generating device 3 is activated, drawing air from the outer periphery of the air inlet 15 through the first cavity 13 into the second cavity 14, and then discharging it through the air outlet 17. In this way, the entrained waste enters the filter box from the air inlet 15, achieving waste collection. The filter frame 2 consists of a base plate 21 and a peripheral plate 22, both of which have filter holes 23. This structure effectively reduces the risk of clogging and ensures stable and sustained suction. When cleaning is required, simply removing the filter frame 2 allows for quick waste disposal, significantly improving maintenance convenience.
[0023] A support plate 24 extends downward from the lower end of the peripheral plate 22, and the support plate 24 bends towards the bottom plate 21 to form a support part 25. Pads 18 are provided at the four corners of the top surface of the partition plate 11, and grooves 19 are formed on the pads 18 for the support plate 24 to be inserted. The arrangement of the support plate 24 and the pads 18 improves the installation stability of the filter frame 2 and creates a gap between the filter frame 2 and the partition plate 11, ensuring a strong suction effect.
[0024] The housing 1 includes a shell 110 and end caps 111. The shell 110 is hollow and open at both ends. There are two end caps 111, which are respectively located at the top and bottom of the shell 110 to close the openings at both ends of the shell 110. One of the end caps 111 has an annular sealing gasket 113 on its inner side. The annular sealing gasket 113 is made of elastic material. The top of the peripheral plate 22 is bent to form a folded edge 26 parallel to the bottom plate 21. The folded edge 26 abuts against the annular sealing gasket 113. The top of the housing 110 is bent to form a bent portion 114. The cross-sectional shape of the bent portion 114 is inverted L-shaped. The horizontal edge of the bent portion 114 abuts against the annular sealing gasket 113. The bottom surface of the annular sealing gasket 113 is provided with a sealing protrusion 115. The sealing protrusion 115 extends between the vertical edge of the bent portion 114 and the peripheral plate 22. The bottom outer periphery of the sealing protrusion 115 is provided with a locking block 116. The locking block 116 is engaged in the gap between the vertical edge of the bent portion 114 and the housing 110. Thus, by setting the annular sealing gasket 113, sealing protrusion 115 and locking block 116, the airtightness between the filter frame 2, end cap 111 and housing 110 can be improved, further ensuring the suction effect.
[0025] To facilitate the control of the negative pressure generating device 3, a control panel (not shown in the figure) is provided on the inner wall of the housing 1. The control panel (not shown in the figure) is electrically connected to the negative pressure generating device 3. The control panel (not shown in the figure) is provided with a display screen 112 and control buttons 12, which are exposed on the surface of the housing 1.
[0026] The negative pressure generating device 3 is a centrifugal turbine.
