The frame 1 is provided with a fresh air inlet 12 and a fresh air outlet 13, and the fresh air inlet 12 and the fresh air outlet 13 are communicated through the pipe cavity of the pipe 11, so that fresh air can enter the pipe cavity of the pipe 11 from the fresh air inlet 12, flow to the position of the fresh air outlet 13 in the pipe cavity of the pipe 11, and flow out from the fresh air outlet 13, that is, the fresh air can flow in a pipeline formed by the fresh air inlet 12, the pipe cavity of the pipe 11 and the fresh air outlet 13. And, the fresh air outlet 13 is communicated with the indoor space, so that fresh air can flow into the pipe cavity of the pipe 11 from the fresh air inlet 12 and flow out of the fresh air outlet 13 into the indoor space of the shelter, and fresh air in the indoor space of the shelter can enter and flow.

At the moment, the air in the indoor space flows into fresh air, so that the air pressure in the indoor space is larger than the air pressure outside the shelter, the air in the indoor space can flow outwards, the air in the indoor space is circulated, the air in the indoor space can be kept in a fresh and clean state, and the comfort level of a user in the process of waiting for the air in the closed indoor space for a long time is improved.

Moreover, the frame 1 comprises the pipe fittings 11, namely the frame 1 of the shelter can be built by the pipe fittings 11, and the building of the shelter by the pipe fittings 11 is easy to operate and realize, so that the shelter can be built quickly and can be used as a temporary living place or a refuge place and the like, and the use of the shelter by a user is facilitated.

In addition, the pipe fitting 11 may be made of various materials, and may be a plastic pipe fitting, such as a PVC (Polyvinyl Chloride) pipe fitting, a PPR (Polypropylene Random) pipe fitting, or a metal pipe fitting, such as a steel pipe fitting, a stainless steel pipe fitting, an aluminum pipe fitting, or another pipe fitting 11, as long as the pipe fitting 11 can be built into a shelter, and the pipe fitting 11 can communicate the fresh air inlet 12 and the fresh air outlet 13 and provide an air circulation pipeline for a shelter space.

And, when the pipe fitting 11 is the plastics pipe fitting or metal pipe fitting, the shelter is after dismantling, and pipe fitting 11 can be retrieved, is deposited to this is built again, green.

As shown in fig. 2 to 5, the pipe member 11 includes a plurality of horizontal pipe members 111 and a plurality of vertical pipe members 112, the plurality of horizontal pipe members 111 are connected to form a horizontal top bracket 11a and a horizontal middle bracket 11b which are oppositely disposed, the plurality of vertical pipe members 112 are connected to form a vertical top bracket 11c and a vertical bottom bracket 11d, the vertical top bracket 11c is located between the horizontal top bracket 11a and the horizontal middle bracket 11b and is respectively connected to the horizontal top bracket 11a and the horizontal middle bracket 11b, the vertical bottom bracket 11d is connected to one end of the vertical top bracket 11c far away from the horizontal top bracket 11a, and the horizontal top bracket 11a, the horizontal middle bracket 11b, the vertical top bracket 11c and the vertical bottom bracket 11d enclose to form the frame 1.

From this, through horizontal top support 11a, horizontal middle support 11b, connection between vertical top support 11c and the vertical bottom support 11d, in order to enclose the frame 1 that closes formation shelter, make the frame 1 of shelter when buildding, can be earlier according to horizontal top support 11a with pipe fitting 11, horizontal middle support 11b, vertical top support 11c and the four big modules of vertical bottom support 11d build up of preliminary connection, then will connect the horizontal top support 11a who is good, horizontal middle support 11b, vertical top support 11c and vertical bottom support 11d build up of connecting, in order to form the frame 1 of shelter, it is simple easy to operate to build the flow.

Alternatively, the shape of the frame 1 enclosed by the horizontal top bracket 11a, the horizontal middle bracket 11b, the vertical top bracket 11c and the vertical bottom bracket 11d may be one of a cylinder, a prism and a cone, and is not limited herein.

The horizontal pipe 111 and the vertical pipe 112 may be made of the same material as the pipe 11, or the horizontal pipe 111 may be made of one material of the pipe 11, and the vertical pipe 112 may be made of another material of the pipe 11, which is not limited herein.

Optionally, the length of the transverse pipe 111 is equal to that of the vertical pipe 112, so that the transverse pipe 111 and the vertical pipe 112 have certain interchangeability, the built frame 1 has a regular shape, the indoor space of the shelter is regular, and a user can fully utilize the indoor space.

Alternatively, the outer diameters of the horizontal pipe members 111 and the vertical pipe members 112 are the same, and thus, the connection between the two horizontal pipe members 111, the connection between the two vertical pipe members 112, and the connection between the horizontal pipe members 111 and the vertical pipe members 112 can be performed using connectors having the same inner diameter, which is easy to purchase, and which can facilitate the connection of the connectors with the horizontal pipe members 111 and the vertical pipe members 112.

In addition, when the vertical pipe fitting 112 is long, one vertical pipe fitting 112 can be used as the vertical top support 11c or the vertical bottom support 11d independently, so that the building of the vertical top support 11c and the vertical bottom support 11d is simplified; when the vertical pipe members 112 have a short length, at least two vertical pipe members 112 may be connected to form one vertical top bracket 11c or one vertical bottom bracket 11d. Specifically, one vertical top support 11c or one vertical bottom support 11d may be determined by connecting several vertical pipes 112 according to the required height of the indoor space of the shelter.

In some embodiments, as shown in fig. 2 and 3, the fresh air inlet 12 is disposed on the first vertical tube member 1121 of the vertical bottom bracket 11d, the fresh air outlet 13 is disposed on the transverse tube member 111 of the transverse top bracket 11a, and the lumen of the transverse tube member 111 of the transverse top bracket 11a is communicated with the lumen of the first vertical tube member 1121.

Thus, fresh air can enter the tube cavity of the tube member 11 from the vertical bottom bracket 11d and then flow out of the fresh air outlet 13 on the transverse top bracket 11a, so that the fresh air can flow downwards from the top of the indoor space in the cabin, and the fresh air can flow into each corner of the indoor space, and the air in each area of the indoor space can be supplemented by the fresh air.

Moreover, the fresh air inlet 12 is disposed on the first vertical pipe 1121 of the vertical bottom bracket 11d, and the fresh air outlet 13 is disposed on the horizontal pipe 111 of the horizontal top bracket 11a, so that the position of the fresh air inlet 12 is lower than the position of the fresh air outlet 13 in the vertical direction. And in the interior space of shelter, when personnel moved about in the interior space, the temperature of interior space can rise for the atmospheric pressure at the top of interior space can be less than the atmospheric pressure of the outside ground annex of interior space, thereby can make the air get into the lumen of pipe fitting 11 from the fresh air import 12 that the position is lower under the effect of atmospheric pressure difference in can making the air, flow out from the fresh air export 13 that the position is higher to in getting into the interior space, improved the air inlet speed of fresh air import 12. And can make the air of indoor space realize the effect of certain natural air inlet, especially, when new trend import 12 was located the position department of air inlet, the effect of natural air inlet can be better.

In some embodiments, the number of the fresh air inlets 12 is one, the number of the fresh air outlets 13 is plural, and the plural fresh air outlets 13 are arranged on the transverse pipe 111 of the transverse top bracket 11a at intervals. Therefore, fresh air can flow in from the fresh air outlets 13 arranged at intervals in the top area of the indoor space of the shelter, so that the air in each area of the indoor space can participate in circulation, and the overall air quality of the indoor space is better.

In addition, the number of the fresh air inlets 12 may also be multiple, for example, two, three, etc., which is not limited herein.

In some embodiments, as shown in fig. 2 and 5, the frame 1 further includes an exhaust air inlet 14 and an exhaust air outlet 15, the exhaust air inlet 14 is disposed on the transverse pipe member 111 of the transverse middle bracket 11b, the exhaust air outlet 15 is disposed on the second vertical pipe member 1122 of the vertical bottom bracket 11d, the second vertical pipe member 1122 is the pipe member 11 except for the first vertical pipe member 1121 in the vertical pipe members 112 of the vertical bottom bracket 11d, the lumen of the transverse pipe member 111 of the transverse middle bracket 11b is communicated with the lumen of the second vertical pipe member 1122, and the exhaust air inlet 14 is communicated with the indoor space. Therefore, turbid air in the indoor space of the shelter can enter the tube cavity of the tube 11 from the exhaust air inlet 14, then flows in the tube cavity of the tube 11 and is exhausted from the exhaust air outlet 15, so that the turbid air in the indoor space can be exhausted, fresh air can be promoted to enter the indoor space from the fresh air inlet 12 and flow into the indoor space, and the air in the indoor space can be continuously renewed and circulated.

Wherein, the air exhaust inlet 14 is arranged on the horizontal pipe fitting 111 of the horizontal middle bracket 11b, the air exhaust outlet 15 is arranged on the second vertical pipe fitting 1122 of the vertical bottom bracket 11d, so that the height of the air exhaust outlet 15 from the ground is lower than the height of the air exhaust inlet 14 from the ground, and the air exhaust inlet 14 is communicated with the indoor space. And, the fresh air outlet 13 is located on the transverse pipe 111 of the transverse top bracket 11a, so that fresh air can be continuously supplemented from the top of the indoor space, and sequentially flows into the middle area and the bottom area of the indoor space, so that the air pressure of the indoor space is slightly greater than the air pressure outside the indoor space, and the turbid air in the indoor space can enter the pipe cavity of the pipe 11 from the exhaust air inlet 14 under the action of air pressure difference, and flows to the exhaust air outlet 15 in the pipe cavity of the pipe 11, so as to exhaust the turbid air in the indoor space.

At this time, because the air in the indoor space is partially exhausted, the air pressure in the indoor space is slightly lower than the air pressure near the ground outside the indoor space, so that the outside fresh air can enter the fresh air inlet 12 under the action of the air pressure difference, flow to the fresh air outlet 13 through the tube cavity of the tube 11, and flow into the indoor space from the fresh air outlet 13, so that the indoor space is supplemented with the fresh air, and the air pressure in the indoor space is increased, so that the original air in the indoor space, namely the turbid air in the indoor space is exhausted from the air exhaust inlet 14 to the tube cavity of the tube 11 and exhausted from the air exhaust outlet 15. Thus, air in the indoor space can be circulated.

Alternatively, the number of the exhaust air inlets 14 may be plural, and specifically, one exhaust air inlet 14 may be provided on each of the transverse pipe members 111 of the transverse middle bracket 11b, so that the relatively turbid air in each region of the indoor space can enter the pipe cavity of the pipe member through the exhaust air inlet 14 and finally be discharged through the exhaust air outlet 15, thereby increasing the exhaust rate of the relatively turbid air in the indoor space.

Alternatively, the number of the exhaust air outlets 15 may be multiple, and specifically, a fresh air exhaust port may be provided on each second vertical pipe member 1122 of the vertical bottom bracket 11d, so that the turbid air in the tube cavity of the pipe member 11 can be exhausted through the multiple exhaust air outlets 15, thereby improving the exhaust rate of the turbid air in the indoor space.

In addition, the exhaust air outlet 15 may be disposed at any position on the second vertical pipe 1122, for example, at a position in the middle of the second vertical pipe 1122, or at an end of the second vertical pipe 1122 away from the transverse middle bracket 11b, which is not limited herein.

And the shelter is provided with a fresh air pipeline consisting of a fresh air inlet 12, a fresh air outlet 13 and a pipe fitting 11 for communicating the fresh air inlet 12 with the fresh air outlet 13, and is also provided with an exhaust pipeline consisting of an exhaust air inlet 14, an exhaust air outlet 15 and a pipe fitting 11 for communicating the exhaust air inlet 14 with the exhaust air outlet 15, so that the shelter is provided with a relatively complete ventilation pipeline, and the circulation effect of air in the indoor space of the shelter is relatively good.

Alternatively, in order to improve the circulation efficiency of the air in the indoor space, a ventilation device (such as a ventilator) may be provided at the fresh air inlet 12 and/or the fresh air outlet 13, or a ventilation device (such as an exhaust fan) may be provided at the exhaust air outlet 15 and/or the exhaust air outlet 15, or a ventilation device may be provided at each of the fresh air inlet 12 and/or the fresh air outlet 13, and the exhaust air outlet 15 and/or the exhaust air outlet 15, so that the fresh air in the indoor space of the shelter can be supplemented without being affected by the outside climate, and the circulation rate of the air in the indoor space can be effectively increased.

Optionally, a filter component, such as a filter screen, may be disposed at the fresh air outlet 13 to filter fresh air entering the indoor space, so that the air entering the indoor space contains less harmful substances, or even no harmful substances, to ensure that people in the cabin can breathe clean and sanitary air.

Alternatively, the exhaust outlet 15 may be communicated with a sterilization and disinfection box, so that the relatively turbid air flowing out of the indoor space is firstly subjected to sterilization and disinfection treatment by the sterilization and disinfection box and then discharged from the sterilization and disinfection box, so that the air discharged from the indoor space does not contain germs, viruses and the like, and the pollution to the external environment is prevented. Particularly, when the shelter is used as an epidemic prevention temporary isolation place, the pollution of the air exhausted from the shelter to the external environment can be effectively reduced, so that the risk of cross infection is reduced.

In addition, the sterilization and disinfection box communicated with the exhaust outlet 15 can be simultaneously communicated with the fresh air inlet 12, namely, the air inlet of the sterilization and disinfection box is connected with the exhaust outlet 15, and the air outlet of the sterilization and disinfection box is connected with the fresh air inlet 12. Therefore, after the air exhausted from the indoor space is sterilized by the sterilization box, the air can directly flow into the fresh air inlet 12 to enter the indoor space again, and the air in the indoor space can be circulated and simultaneously can be prevented from containing germs and viruses to cause cross infection.

Of course, the fresh air inlet 12 may be only communicated with the sterilization and disinfection box, so that the fresh air entering the indoor space does not contain the contaminants such as germs and viruses, and the like, which is not limited herein.

In some embodiments, the lumen of the second vertical tube 1122 is isolated from the lumen of the first vertical tube 1121, and the lumen of the transverse tube 111 of the transverse middle bracket 11b is isolated from the lumen of the transverse tube 111 of the transverse top bracket 11 a. Therefore, the tube cavity of the vertical tube 112 for circulating fresh air and the tube cavity of the vertical tube 112 for exhausting air can be isolated from each other, the tube cavity of the horizontal tube 111 for circulating fresh air and the tube cavity of the horizontal tube 111 for exhausting air are isolated from each other, namely, the tube cavity of the tube 11 for circulating fresh air and the tube cavity of the tube 11 for exhausting air in the frame 1 are isolated from each other, so that fresh air can only flow in the tube cavity of the first vertical tube 1121 and the tube cavity of the horizontal tube 111 of the horizontal top bracket 11a in the frame 1, turbid air exhausted from the indoor space can only flow in the tube cavity of the second vertical tube 1122 and the tube cavity of the horizontal tube 111 of the horizontal middle bracket 11b, and the mixing condition of the fresh air and the turbid air needing to be exhausted when the fresh air and the turbid air flow in the tube cavities of the tube 11 is prevented.

Wherein, the first vertical pipe 1121 and the second vertical pipe 1122 are connected only through the vertical top support 11c and the horizontal top support 11a, and a plug can be embedded in the tube cavity of the vertical pipe 112 in the vertical top support 11c, so that the tube cavity of the first vertical pipe 1121 and the tube cavity of the second vertical pipe 1122 can be isolated from each other, and the tube cavity of the horizontal pipe 111 in the horizontal top support 11a and the tube cavity of the pipe 11 in the horizontal middle support 11b can be isolated from each other, and the structure is simple and easy to realize.

Optionally, as shown in fig. 6 and fig. 7, a transverse connecting pipe 17 may be further connected between the first vertical pipe 1121 and the second vertical pipe 1122, and a plug 171 is disposed on the transverse connecting pipe 17, and the plug 171 may be embedded at two ends of a lumen of the transverse connecting pipe 17, so that the lumen of the first vertical pipe 1121 and the lumen of the second vertical pipe 1122 are isolated from each other, and at the same time, the first vertical pipe 1121 and the second vertical pipe 1122 may be firmly connected to improve the firmness of the frame 1.

In the pipe 11, the connection between two adjacent transverse pipe members 111, two adjacent vertical pipe members 112, and the adjacent transverse pipe members 111 and vertical pipe members 112 has various implementations. In a possible implementation, the tube 11 further comprises a heat shrink tubing, by which two adjacent transverse tubes 111, two adjacent vertical tubes 112 and between the adjacent transverse tubes 111 and vertical tubes 112, can be connected. For example, taking two adjacent transverse pipes 111 as an example for description, one end of a heat-shrinkable sleeve with an inner diameter slightly larger than the outer diameter of the pipe 11 is sleeved on one end of one of the two adjacent transverse pipes 111, the other end of the heat-shrinkable sleeve is sleeved on one end of the other transverse pipe 111, and then the heat-shrinkable sleeve is heated by a hot air blower to shrink the heat-shrinkable sleeve and tightly sleeved on the transverse pipe 111 to connect the two adjacent transverse pipes 111, so that the operation is simple and convenient.

In another possible implementation, as shown in fig. 2 and 6, the frame 1 further includes a pipe connector 16, the pipe connector 16 is detachably connected between two adjacent pipe members 11, that is, the pipe connector 16 is detachably connected between two adjacent transverse pipe members 111, two adjacent vertical pipe members 112, and two adjacent transverse pipe members 111 and vertical pipe members 112, and the fresh air inlet 12 is disposed on the pipe connector 16, and/or the fresh air outlet 13 is disposed on the pipe connector 16.
