DETAILED DESCRIPTION

[0023] In order to make the technical personnel in the field better understand the technical scheme of the utility model, the utility model will be further introduced in detail below in combination with the drawings.

[0024] The utility model provides a kind of micro-positive pressure environment monitoring device as Figures 1-5 As shown in a kind of micro-positive pressure environment monitoring device, including door panel 1, the controller 9 is fixedly arranged on the front side of door panel 1, and the front side is towards outdoor, and the back side is towards indoor, air pressure sensor 4 is fixedly arranged on the front and back sides of door panel 1, air pressure sensor 4 is arranged at the input end of controller 9, display screen 6 is arranged on the front and back sides of door panel 1, the bottom of display screen 6 is equipped with a plurality of strip-shaped light bands 7, and strip-shaped light band 7 is fixedly arranged on door panel 1, and display screen 6 and strip-shaped light band 7 are arranged at the output end of controller 9.

[0025] Door panel 1 is installed at the entrance and exit of a room, and door panel 1 can be used as an ordinary door, has the basic function of door, when the room is in micro-positive pressure environment, two air pressure sensors 4 installed on door panel 1 are separated by door panel 1 in indoor and outdoor, and two air pressure sensors 4 detect the air pressure in indoor and outdoor respectively, and the relevant air pressure data is displayed on two display screens 6 by controller 9, the display contents of two display screens 6 are same, and indoor and outdoor personnel can see, so as to grasp the air pressure situation in indoor and outdoor in real time.

[0026] Before opening door panel 1, prompt is needed, and the person who opens door is reminded to observe air pressure data, such as Figure 2 、 3,5 as shown, the door panel 1 is provided with electronic lock 5, the electronic lock 5 is provided with two handles 13 inside and outside, one end of the handle 13 is fixedly provided with light sensor 14, the light sensor 14 is arranged at the input end of the controller 9, one side of the handle 13 is provided with auxiliary handle 12, the auxiliary handle 12 includes center rod 1201, the outer end of the center rod 1201 is sleeved with hollow handle 1202 which can slide, when opening the door, the light sensor 14 is located inside the hollow handle 1202.

[0027] The auxiliary handle 12 further includes end plate 1204, the end plate 1204 is fixedly arranged at one end of the center rod 1201 away from the handle 13, the hollow handle 1202 and the end plate 1204 are provided with positioning spring 1203, the two ends of the positioning spring 1203 are fixedly connected with the two, and the positioning spring 1203 is sleeved on the outer end of the center rod 1201.

[0028] Opening the door panel 1 needs to open the electronic lock 5 and rotate the handle 13 on the electronic lock 5, but the size of the handle 13 is small, and it is inconvenient to rotate directly, at this time the hollow handle 1202 can be held by hand, and the hollow handle 1202 is transversely pulled to make it slide on the outer end of the center rod 1201 and approach the handle 13 until the handle 13 is inserted into the hollow handle 1202, at this time the auxiliary handle 12 is connected with the handle 13 as a whole under the action of the hollow handle 1202, and when no one operates, the positioning spring 1203 pulls the hollow handle 1202 back to the original position and separates from the handle 13.

[0029] At the same time, the light sensor 14 is also sleeved into the hollow handle 1202, the shielding effect of the hollow handle 1202 makes the ambient brightness where the light sensor 14 is located decrease, so the light sensor 14 controls the strip-shaped light band 7 to flash through the controller 9, and the light is used to prompt, so that the person who is about to open the door panel 1 can notice the strip-shaped light band 7 and the display screen 6 close to the strip-shaped light band 7, and then notice the air pressure value on the display screen 6, so as to judge whether the indoor environment is in a slightly positive pressure environment, if yes, the door panel 1 can be opened, if not, the indoor air pressure needs to be adjusted, and the door panel 1 is opened after the slightly positive pressure environment is restored, the prompting effect of this way is better, and the value on the display screen 6 can be observed before the door panel 1 is opened.

[0030] After the operation is completed, the auxiliary handle 12 as a whole will also return to the original position, as shown in Figure 2 The door panel 1 is slidably connected with the sliding block 10 through the arc-shaped sliding rail on the front and rear sides, the end plate 1204 is fixedly arranged at the front side of the sliding block 10 on the corresponding side, the top end of the sliding block 10 is fixedly provided with reset spring 11, and the top end of the reset spring 11 is fixedly connected with the door panel 1.

[0031] In the process of connecting the auxiliary handle 12 with the handle 13 and rotating the handle 13, the sliding block 10 connected with the auxiliary handle 12 is driven to slide downward along the arc-shaped sliding rail, and the return spring 11 is lengthened, and when no one operates, the elastic force of the return spring 11 is released to pull the sliding block 10 and the auxiliary handle 12 to return to the original position.

[0032] The door plate 1 is inlaid with a transparent window 8, which is arranged at the top of the display screen 6, and the transparent window 8 is made of tempered glass, so that the indoor environment can be observed through the transparent window 8, and the outdoor environment can also be observed through the transparent window 8.

[0033] In order to intuitively determine whether there is a pressure difference between the indoor and outdoor environments, as shown in the drawings, a plurality of air permeable micropores 2 are arranged on the door plate 1, the air permeable micropores 2 penetrate the door plate 1, the diameter of the air permeable micropores 2 is less than 1 cm, and the air permeable micropores 2 are arranged in a matrix. Figure 1 4 The door plate 1 is inlaid with a transparent window 8, which is arranged at the top of the display screen 6, and the transparent window 8 is made of tempered glass, so that the indoor environment can be observed through the transparent window 8, and the outdoor environment can also be observed through the transparent window 8.

[0034] The door plate 1 is inlaid with a transparent window 8, which is arranged at the top of the display screen 6, and the transparent window 8 is made of tempered glass, so that the indoor environment can be observed through the transparent window 8, and the outdoor environment can also be observed through the transparent window 8.

[0035] The indoor and outdoor environments are not completely closed, and under the micro-positive pressure environment, due to the pressure difference, the indoor air can flow outward through the air permeable micropores 2, and the fresh air treated by the corresponding equipment can also be continuously input into the indoor environment, so that under the micro-positive pressure environment, air flow should flow at the air permeable micropores 2, and the ribbons 302 close to the air permeable micropores 2 will flutter under the influence of the air flow, and under the normal micro-positive pressure environment, the ribbons 302 in the indoor environment are close to the door plate 1 under the action of the air flow, and the ribbons 302 in the outdoor environment are away from the door plate 1 under the action of the blown air, so that the flow direction of the air flow can be determined by observing the prompt assembly 3, and the indoor environment under the micro-positive pressure environment can be intuitively determined.

[0036] The above only describes some exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the present application.​
