Specific embodiment
As shown in Figure 1, a kind of novel negative pressure weighs cover, including cabinet 100, it is separated into inside the cabinet 100 by partition
Operating room 110, negative pressure chamber 120 and plemum 130, the negative pressure chamber 120 are located at 110 rear of operating room, and plemum 130 is located at behaviour
Make 110 top of room, 110 rear wall lower part of operating room is provided with the air outlet 111 communicated with negative pressure chamber, 110 rear wall of operating room
Top is provided with headlamp 112, and 100 back lower of cabinet is provided with the air inlet 121 communicated with negative pressure chamber 120, before cabinet 100
Upper lateral part is provided with the exhaust outlet 131 communicated with plemum, offers the leeward communicated with plemum 130 at the top of operating room 110
Mouthfuls 113, primary filter 122 and medium effeciency filter 123 are provided in negative pressure chamber 120, are provided with high efficiency particulate air filter in plemum
132, be provided with stream film 133 at lower air port, it is rationally distributed that the utility model negative pressure weighs cover, by primary filter 122 and in imitated
The setting of filter 123 can discharge the indoor space of operation significantly in negative pressure chamber, and operating room space becomes larger, and staff can be into
Enter into operating room to carry out weighing operation, it is easy to use, while air inlet being arranged in the rear side of cabinet, air inlet and air outlet
It is oppositely arranged, part enters in operating room and pollutes and operate indoor air when outside air being avoided to enter from air inlet.
In the present embodiment, it is provided on front side of the cabinet 10 to seal the front of operating room 110 and can outwardly open
Chamber door 140 is provided with weight-scale table 150 in the operating room, when staff enters operating room, chamber door is shut, operating room with
Outside air isolation, it is ensured that operating room forms the working environment for generating a cleaning sterile.
In the present embodiment, it is provided with the volume damper 134 to adjust air-out volume at the exhaust outlet 131, arranges
The air quantity of the discharge of air port 131 10% to 15%, while the air in the external world is drawn as supplement, so in operating room by air inlet
The pressure of pressure opposite outer be in tiny structure, it is dirty so as to avoid the intersection that leaks between drug of material during weighing
Dye, passes through the size of the adjustable exhaust air rate of volume damper；Oneself for only allowing one-way air inlet is provided at the air inlet 121
Hang down formula air grille 124, and filter is provided at the air outlet 111, and air inlet is adaptive by self hang down type air grille 124
