The partition 12 of the second configuration area 102 . The casing 11 has a body 111 formed with a maintenance port 116 connected between the outside world and the first configuration area 101, and two two holes located on opposite sides, which together with the body 111 surround the inner space 100 and form a There is an air inlet plate 112 with a plurality of openable and closable slots 110, and a cover plate 113 that can openably close the maintenance port 116. Specifically, the shape of the main body 111 of the casing 11 can be adjusted according to conditions such as the configuration environment, the amount of air intake to be processed, the appearance design, etc., as long as enough of the inner space 100 can be surrounded.

Referring to FIG. 2 , each air inlet plate 112 can switch between an air inlet state in which the through slots 110 are open, and a blocking state in which the through slots 110 are closed. Specifically, each air inlet plate 112 can be made of two plates 118 formed with a plurality of slots 119, and can be adjusted and switched by loosening and fixing the locking members 117 such as screws, so that the plates can be The slots 119 of the sheet 118 are aligned with or offset from each other. That is, when the slots 119 of the plates 118 are aligned with each other, they can be switched to the air inlet state in which the slots 110 are open; and when the slots 119 of the plates 118 are misaligned with each other, that is, It is to switch to the blocking state in which the through slots 110 are closed.

Referring again to Figure 1 and in conjunction with Figure 3, the partition 12 has a plurality of through-holes 120, and the processing unit 2 includes a plurality of filter module modules 21 respectively installed in the through-holes 120, and a plurality of fixed Antibacterial lamp 22 in the inner space 100 . Among them, the antibacterial lamp 22 is preferably a lamp that can emit short-wave ultraviolet light (UVC), but specifically, as long as the antibacterial effect can be achieved, it is not limited to this.

As shown in Figure 3, each filter element module 21 has a base 211, a filter element 212 that is detachably sleeved on the base 211 and surrounds the base 211 to define a processing chamber 210, and a filter element 212 from the base. The bracket 213 extends to the processing chamber 210, and a plurality of light-emitting components 214 are installed on the bracket 213. The base 211 has a mesh plate 218 formed with a plurality of pores 219 connected between the respective processing chambers 210 and the second configuration area 102 (see Figure 4), thereby preventing relatively upper parts from falling, and at the same time The through holes 120 must be maintained in a state where gas can pass through. The filter element 212 has a hollow cylindrical filter material part 216, and an end cap part 217 provided at an end of the filter material part 216 away from the base 211. Specifically, the filter material part 216 can use HEPA (High-Efficiency Particulate Air) grade high-efficiency filter material, which can effectively filter tiny particles in the air, such as dust or PM _2.5 grade dust (particle diameter less than or equal to 2.5 microns). suspended particulates), etc., to improve the effect of air purification. The gas passing through the filter material part 216 will also be illuminated by the light emitted by the light-emitting component 214 in the processing chambers 210.

Referring back to Figure 1, it should be noted that since the maintenance port 116 of the casing 11 faces the filter element modules 21, when the filter element modules 21 need to be replaced, just open the cover 113, that is, The maintenance port 116 can be easily operated to conveniently replace the filter element modules 21 .

Referring to Figures 4 and 5 in conjunction with Figure 1, the air guide unit 3 includes an air extraction valve 31 connected to the first configuration area 101, and is located in the second configuration area 102 and has an input port 321 and an output. The fan 32 has a port 322. Among them, the exhaust valve 31 can use an orifice plate 311 formed with a through hole 319 as shown in FIG. When the air extraction valve 31 is connected, the alignment plate 312 of the pipe 318 is opened; or as shown in FIG. 7 , a guide tube 313 connected to the air extraction valve 31 is provided with a guide tube 313 that can rotate to achieve closure. and open valve plate 314. Moreover, in addition to the forms shown in FIGS. 6 and 7 , as long as the air extraction valve 31 can be opened and closed smoothly and a considerable degree of air tightness is achieved, it is not limited to the above two forms.

Continuing to refer to FIGS. 4 and 5 , the fan 32 is located directly below the filter element modules 21 , and the input port 321 is located at one end and spaced apart from the longitudinal projection range of the filter element modules 21 . Regardless of whether the gas is sucked by the air extraction valve 31 or introduced into the first configuration area 101 through the air inlet plates 112, the air will be guided by the fan 32 toward a specific space through the filter element molds. After the group 21 is processed, it enters the second configuration area 102 through the through holes 120 . Then, the gas that enters the second arrangement area 102 will flow laterally as shown in FIG. 4 because the input port of the fan 32 and the through holes 120 still have a lateral distance, and then pass through the input port 321 Entering the fan 32 thereby prolongs the gas flow path, which is more conducive to making the air flow smoother without interruption according to the air intake state.

The exhaust guide unit 4 is detachably installed on the output port 322 of the fan 32 of the air guide unit 3, and is used to guide the gas output from the output port 322. The drainage unit 4 includes a conduit 41 having a connection port 411 for connecting to the output port 322 and an outlet port 412 opposite to the connection port 411 . Specifically, the exhaust guide unit 4 selects a more suitable connecting element according to the space where the processed gas is to be led out. Since the conduit 41 is more conducive to extending the path and bending the configuration, it is more conducive to guiding the processed gas. Lead to a specific space.

Referring to FIG. 8 in conjunction with FIG. 4 , a usage scenario for forming negative pressure in a space S1 to be treated through the first embodiment is shown. Among them, the air inlet plate 112 on one side faces the space S1 to be treated, and is switched to the air inlet state. When the exhaust valve 31 is closed and the fan 32 continues to operate, the gas in the space S1 to be treated will enter the first configuration area 101 through the channels 110 and be processed by the antibacterial lamps 22 , and then through filtration and further bacteriostasis by the filter module 21, the bacteriostatic light emitted by the bacteriostatic lamps 22 is irradiated in the second configuration area 102, that is, due to the operation of the fan 32 It is led out via the conduit 41 . When the space to be treated S1 is, for example, a ward, the space to be treated S1 can be made to have a lower pressure than the outside air, thereby achieving the purpose of creating a negative pressure ward.

Next, refer to Figure 9 in conjunction with Figure 4, which shows the situation in which the first embodiment is connected to the outside world and introduces gas. When the air extraction valve 31 is opened to the outside, the outdoor air is sucked through the air extraction valve 31. After entering the inner space 100, it will be treated by the bacteriostatic lamps 22, and after being filtered and further bacteriostatic by the filter module modules 21, it will be introduced into the space to be treated S1 through the conduit 41. Among them, since the air inlet plate 112 on one side faces the space S1 to be treated, as long as the air inlet plate 112 is switched to the blocking state, outdoor air can only be introduced into the space S1 to be treated. demands.

It should be noted that the air extraction valve 31 can be conveniently connected to a specific object. The space corresponding to the air extraction valve 31 can also be the ward of patients with concerns about infectious diseases such as Covid-19. At this time, the air inlet plates 112 can be switched to the blocking state, thereby extracting air in an environment with a risk of air infection, and also through the processing of the antibacterial lamps 22 and the filter module 21 to achieve filtration , antibacterial effect, thereby reducing the risk of infection caused by air circulation.

Referring to Figure 10, when the first embodiment is operating, the air extraction valve 31 can also be closed. If the air inlet plates 112 are respectively facing two independent spaces to be treated S11 and S12 as an example, at this time The continuous operation of the fan 32 can, when the air inlet plates 112 are in the air intake state, not inlet air from the space corresponding to the air extraction valve 31, but simply from the air inlet plates 112. Through slot 110 air intake. Accordingly, if the space corresponding to the air extraction valve 31 is outside, it can perform a function similar to air filtering of the waiting spaces S11 and S12 without introducing outside air.

Referring to Figure 11, a second embodiment of the mobile negative pressure sterilization machine of the present invention is shown. The difference between the second embodiment and the first embodiment is that the drainage unit 4 includes a plurality of slots. The grille 42 at 420, that is, the accessory connected to the fan 32, is changed from the duct 41 (see Figure 1) of the first embodiment to the grille 42. Next, referring to Fig. 11 and in conjunction with Fig. 4, Fig. 11 shows a situation in which air filtration is achieved for a space S2 to be treated through the second embodiment. The air in the space S2 to be treated can directly enter the first configuration area 101 through the air extraction valve 31 or the slots 110, and can also be irradiated with light from the antibacterial lamps 22 to inhibit bacteria, as well as the filter modules. 21 After filtration and bacteriostasis, it is then guided back to the space S2 to be treated through the slots 420 of the grille 42 through the fan 32. When the space S2 to be treated is closed, in addition to preventing the air from being exported to the outside, the effect of circulating and cleaning the air can also be achieved.

Referring to Figure 12, a third embodiment of the mobile negative pressure sterilization machine of the present invention is shown. The difference between this third embodiment and the first embodiment is that: the drainage unit 4 includes a The connecting port 431 of the output port 322, and the manifold 43 of the two air guide ports 432 which are spaced apart from each other and are respectively located at opposite ends to the connecting port 431. As shown in Figure 12, the third embodiment is used to process the two spaces S32 and S33 to be treated, and at the same time introduce the air from the outside S31 to reduce the carbon dioxide concentration. When the air extraction valve 31 is opened and the air inlet plates 112 are switched to the air inlet state, the air in the waiting spaces S32 and S33 can be introduced into the inner space 100 through the slots 110 . At the same time, external air will also enter the inner space through the air extraction valve 31 and mix with the air from the waiting spaces S32 and S33, thereby balancing the carbon dioxide concentration indoors and outdoors. Similarly, the air will also be processed by the antibacterial lamps 22 and the filter modules 21 as shown in Figure 4. When the carbon dioxide is also reduced due to mixing with the outside air, it will pass through the manifold again. The air guide ports 432 of 43 lead back to the waiting processing spaces S32 and S33 respectively.

Referring to FIG. 13 , another implementation aspect of the third embodiment is shown. The difference from the aspect shown in FIG. 12 is that the air guide ports 432 of the manifold 43 can be extended to different directions and can be respectively Two gas control valves 439 are configured, and the air guide ports 432 can be connected to indoors and outdoors respectively. When the air extraction valve 31 is connected to the outdoors and the gas control valves 439 are all opened, the filtered and bacteriostatic gases will be discharged to the outdoors and indoors respectively. While providing clean gas, it can also avoid continuous carbon dioxide concentration. rise. In addition, through the gas control valves 439, the gas configuration can also be adjusted to effectively solve the problem.

To sum up, the mobile negative pressure sterilization machine of the present invention switches the air inlet or blocking state of the air inlet plates 112, and cooperates with the air inlet state of the exhaust valve 31 connected to the specific space, and the exhaust state. The selection and installation of the guide unit 4 can create the required negative pressure environment according to the existing environment or needs, or achieve air filtration and antibacterial effects, and cooperate with the relative position between the fan 32 and the filter module 21 The location can make good use of the limited internal space 100, extend the air flow path according to the air extraction state, ensure the smoothness of air suction and discharge, and effectively optimize the performance of creating a negative pressure environment. Therefore, the purpose of the present invention can indeed be achieved.
