[0031] To enable those skilled in the art to better understand the solution of the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Specifically, as Figure 1 shown, a laboratory waste collection device specifically includes: a box body 1, a cover body 2 rotatably connected to the top end of the box body 1, and a base 3 fixed to the bottom of the box body 1, wherein the base 3 is divided into a first and a second chamber by a partition; as Figure 2 shown, the top of the box body 1 is open, for putting the waste generated in the laboratory through the opening, and one side of the cover body 2 is rotatably connected to one side of the opening at the top of the box body 1, so that the cover body 2 can rotate around the rotation point to block or not block the opening of the box body 1.

[0033] As Figure 2 shown, a suction mechanism 4 is provided between the base 3 and the box body 1, which is used to suck out the peculiar smell or toxic smell generated in the box body 1 due to the collection of waste, and filter and purify the sucked gas through a purification member 5 before discharging, so as to avoid the influence of the peculiar smell or toxic smell on the experimental personnel and improve the use experience of the experimental personnel.

[0034] Furthermore, as Figure 3 and Figure 4 shown, the suction mechanism 4 includes a fan 41, a suction pipe 42 and a connecting pipe 43. The fan 41 is installed in the first chamber of the base 3, and the input port of the fan 41 is communicated with one end of the suction pipe 42. The other end of the connecting pipe 43 passes through the back of the box body 1 and then penetrates into the box body 1 near the outside of the opening at the top of the box body 1. Since the suction pipe 42 is fixed near the opening at the top of the box body 1 of the box body 1, it is communicated with the other end of the connecting pipe 43; because the suction pipe 42 is arranged in a shape around the inner wall of the box body 1 and the air inlet is opened downward on the suction pipe 42, it can avoid affecting the input of waste and make the air inlet holes evenly distributed. When the fan 41 is started, the centrifugal suction force generated by it can suck in the peculiar smell or toxic smell through the air inlet holes evenly distributed on the suction pipe 42; as Figure 1 shown, the purification member 5 is arranged on the output port of the fan 41 and extends out of the first chamber and is integrally connected with a flange, so that the sucked peculiar smell or toxic smell will pass through the filtration and purification of the purification member 5 and be discharged as a non-toxic and odorless gas.

[0035] Furthermore, as Figure 5As shown in the figure, the purification component 5 includes a housing 51, a filter body 52 and a baffle 53. One end of the housing 51 is hollow along the axis and is detachably connected to the flange. Specifically, one end of the housing 51 is in an opening shape adapted to the flange. In this way, the housing 51 can be connected by sleeving the opening at one end on the flange, and it can be pulled off with force during disassembly. Or the flange and the opening at one end of the housing 51 are connected by threads, so that the connection or disconnection with the flange can be completed by screwing. Or it can be connected by bolts; the filter body 52 is placed inside the housing 51, and the baffle 53 is inserted into the other end of the housing 51 and restricts the filter body 52 to be located between the flange and the baffle 53 inside the housing 51. In this way, the sucked gas will be discharged into the housing 51, and the filter body 52 adsorbs the gas molecules in the gas to achieve the effect of purifying the gas. Specifically, the filter body 52 can be one or a combination of activated carbon, molecular sieve, ceramic, polyimide, and polycarbonate, which is determined according to the actual application.

[0036] Furthermore, the baffle 53 includes a baffle plate and an isolation frame. The baffle plate is larger than the diameter of the housing 51 and is provided with exhaust holes on its surface. The diameter of the isolation frame is the same as the inner diameter of the housing 51 and is integrally connected to the baffle plate to prevent the filter body 52 from contacting the baffle plate; the isolation frame can be inserted or threadedly connected into the other end of the housing 51 and contacts the filter body 52 located in the housing 51, so that the filter body 52 will not contact the baffle plate and avoid blocking the exhaust holes opened on the baffle plate. In this way, the gas that has been filtered and purified by the filter body 52 will be discharged through the exhaust holes on the baffle plate. It should be noted that the shapes and structures of the filter body 52 and the isolation frame are only for illustration, and the filter body 52 and the isolation frame are adjusted according to the shape of the housing 51 that plays a bearing role. Figure 5 Only for illustration, the filter body 52 and the isolation frame are adjusted according to the shape of the housing 51 that plays a bearing role.

[0037] As Figure 6 As shown in the figure, a sloping plate 7 is fixed at the bottom of the box body 1 corresponding to the first chamber, so as to form a slope at the bottom of the box body 1. Through grooves are opened in the bottom of the box body 1 corresponding to the second chamber and in the second chamber along the up and down directions. A filter plate 6 is placed between the slope and the through groove at the bottom of the box body 1. The filter plate 6 includes a number of protrusions 61, and filter holes 62 are opened on each of the number of protrusions 61. The liquid poured into the box body 1 will enter the second chamber through the filter holes 62 and the through grooves opened in the bottom of the box body 1 and in the second chamber along the up and down directions. A liquid collecting box 8 is placed in the second chamber, so that the filtered liquid is concentrated in the liquid collecting box 8, and the liquid collecting box 8 can be pulled out of the second chamber to facilitate the cleaning of the liquid concentrated inside.

[0038] In some instances, in order to ensure that the liquid collecting box 8 is not misplaced in the second chamber and avoid some of the filtered liquid from spilling in the second chamber, one end of the liquid collecting box 8 leaking in the second chamber is connected to the base 3 through a locking member 9 (such as Figure 2Fixedly connected as shown in the partial enlargement. When the locking fastener 9 is in the locked state, the liquid collecting box 8 is placed in the second chamber in a fitting manner. When the locking fastener 9 is in the loosened state, the liquid collecting box 8 can be pulled out from the second chamber. Specifically, the locking fastener 9 includes a base fixed on the base 3, a locking tongue rotatably connected to the base and provided with a rotational damping force by a spring, and a stop block fixed on the liquid collecting box 8. When the locking tongue is on one side of the stop block, it restricts the liquid collecting box 8 from being pulled out of the second chamber. Rotate the locking tongue and compress the spring to disengage from the stop block. At this time, the liquid collecting box 8 can be pulled out from the second chamber.

[0039] As Figure 7 As shown, the filter plate 6 further includes an outer frame 63 for connecting a plurality of protrusions 61. There is a gap between at least a part of the protrusions 61 of the outer frame 63 and the slope, that is, the outer frame 63 slightly raises the height of a plurality of protrusions 61 at its top on the slope so that the protrusions 61 do not contact the slope; each of the plurality of protrusions 61 has two inclined sides and a placing end connecting the two inclined sides; the filter holes 62 are formed on the inclined sides; during use, the poured waste will contact between the placing ends of the plurality of protrusions 61, so that the filter holes 62 located on the inclined sides will not be blocked. In this way, the liquid will continue to move downward to the area between the inclined sides of one protrusion 61 and the inclined sides of another protrusion 61, and be discharged from the filter holes 62 on the inclined sides into the second chamber on the base 3. Part of the liquid flows along the slope and is discharged into the second chamber on the base 3, that is, concentrated in the liquid collecting box 8.
