Description

Technical Field

[0001] This utility model relates to the field of tent technology, specifically to a multi-tent inflation and deflation device. Background Technology

[0002] Currently, tent inflation devices require an air pump to inflate the tent when it is deployed and an air pump to evacuate the air when it is collapsed. A set of tents needs to be equipped with two pumps, one for inflation and one for evacuation. One pump can only inflate one tent at a time, which is inefficient. A search revealed that Chinese patent CN201165772Y discloses an inflatable tent, including a closed frame airbag. The frame airbag has a horseshoe-shaped cross-section with an air inlet, an air outlet, a partition window, and a zipper door. A fan connected to a DC motor is installed on the air inlet, and a control valve is installed on the air outlet pipe of the fan. The shortcomings of the above patent are: the above patent can only inflate or deflate one tent at a time. When there are multiple tents, each tent needs to be equipped with a fan, which is costly. If a fan is used to inflate or deflate another tent after one tent is finished, the efficiency of inflating or deflating multiple tents in turn is too low. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies and provide a multi-tent inflation / deflation device that is simple in structure, can inflate and deflate multiple tents at once, has low operating costs, and is highly efficient.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The diversion device of this utility model includes a diversion chamber, which is provided with a chamber air inlet and a diversion interface. The exhaust port of the fan is connected to the chamber air inlet of the diversion chamber via a pipeline, so as to facilitate the inflation and deflation of multiple tents at one time through multiple diversion interfaces on the diversion chamber.

[0007] The present invention describes a fan with a fixed exhaust duct at its exhaust port and an fixed intake duct at its inlet. An exhaust three-way ball valve is installed on the exhaust duct. The first end of the exhaust three-way ball valve is fixedly connected to the exhaust duct, the second end of the exhaust three-way ball valve is connected to the intake port of the distribution chamber, and the third end of the exhaust three-way ball valve is a free exhaust end. The distribution chamber has an exhaust port. An intake three-way ball valve is installed on the intake duct.

The tent is connected to the air outlet. The third end of the three-way ball valve is a free air intake end. When the tent needs to be inflated, the three-way ball valves are rotated to allow air to enter the air intake duct through the third end of the three-way ball valve, then through the fan, exhaust duct, distribution chamber, and distribution interface into the tent. When the tent needs to be evacuated, the three-way ball valves are rotated to allow air to enter the distribution chamber through the distribution interface, then through the air outlet of the chamber, and finally through the three-way ball valve to the air intake duct, and then through the fan, exhaust duct, and the third end of the three-way ball valve to be discharged.

[0008] The present invention has an electrical control cabinet on one side of the fan, and the electrical control cabinet contains a control system and a power supply.

The two ends are connected to the air outlet of the diversion chamber 3. The third end of the inlet three-way ball valve 7 is a free air inlet end, which is convenient for inflating the tent. When the tent needs to be inflated, the inlet three-way ball valve and the exhaust three-way ball valve are rotated so that the gas enters the air inlet pipe through the third end of the inlet three-way ball valve, passes through the fan, the exhaust pipe, the diversion chamber, and the diversion interface into the tent. When the tent needs to be evacuated, the inlet three-way ball valve and the exhaust three-way ball valve are rotated so that the gas enters the diversion chamber from the tent through the diversion interface, enters the air inlet pipe through the air outlet of the chamber, and is discharged through the fan, the exhaust pipe, and the third end of the exhaust three-way ball valve.

[0023] The present invention provides an electrical control cabinet 8 on one side of the fan 1, which contains a control system and a power supply. The fan 1 is connected to the control system and the power supply to achieve automatic control of the fan through the control system.

[0024] The fan 1 described in this utility model is placed on the support frame 9. The fan 1, electrical control cabinet 8, air inlet pipe 5, air outlet pipe 4, and diversion chamber 3 are respectively fixedly connected to the support frame 9. The lower end of the support frame 9 is equipped with rollers 10 to facilitate the support of the fan and other components, and to integrate all components on the support frame for easy movement with the tent.

[0025] A pressure gauge 11 is fixedly installed on the diversion chamber 3, air inlet pipe 5, or air outlet pipe 4 of this utility model. The pressure gauge 11 is connected to the control system so that the pressure of the tent inflation and deflation can be known in real time through the pressure gauge, and the pressure value can be transmitted to the control system to control the start and stop of the fan.

[0026] The air inlet pipe 5 of this invention is provided with a filter 12 on one side. The air outlet of the filter 12 is connected to the third end of the air inlet three-way ball valve 7, so as to facilitate the purification of the gas through the filter and improve the service life of the fan.

[0027] The diversion chamber 3 of this utility model is provided with a diversion pipe 13 fixedly installed on the diversion interface. A diversion control valve 14 is fixedly connected to the diversion pipe 13 so as to facilitate the control of each diversion pipe through the diversion control valve and to inflate and deflate several tents in a group of tents as needed.

[0028] As attached Figure 1-4The control system inside the electrical control cabinet 8 can be a PLC control system. The fan 1 can be a high-pressure fan. The fan 1, pressure gauge 11, and filter 12 are all connected to the PLC control system. The number of diversion interfaces on the diversion chamber 3 can be set according to requirements. Each diversion interface is fixed with a diversion control valve 14 via a diversion pipe 13. This allows for the inflation and deflation of all tents connected to the diversion pipes 13 as needed, or it can close some of the diversion pipes 13, allowing inflation and deflation only of tents with open diversion pipes 13. The choice depends on the requirements. The diversion control valve 14 can be a ball valve, as long as it can control the opening and closing of the diversion pipes 13. (See attached...) Figure 2 In this embodiment, there are 7 diversion pipes 13, which can simultaneously inflate or deflate 7 or fewer tents. One diversion pipe 13 corresponds to one tent to be inflated or deflated.

[0029] When the tent needs to be inflated, see attached... Figure 3 Connect the diversion pipe 13 to the tent that needs to be inflated through the pipeline. Manually turn the air inlet three-way ball valve 7 to connect the air inlet pipe 5 to the filter 12. Manually turn the exhaust three-way ball valve 6 to connect the exhaust pipe 4 to the diversion chamber 3. The control system starts the fan 1. The gas enters the air inlet pipe 5 from the filter 12, enters the fan 1, comes out from the exhaust pipe 4, enters the diversion chamber 3 through the exhaust three-way ball valve 6, and then enters the tent through the diversion interface, diversion pipe 13, and diversion control valve 14 for inflation. After inflation is complete, disconnect the tent from the diversion pipe 13.

[0030] When it is necessary to ventilate the tent, see attached Figure 4 Connect the diversion pipe 13 to the tent that needs to be inflated via a pipeline.

[0031] Manually turn the intake three-way ball valve 7 to connect the intake duct 5 to the distribution chamber 3, and manually turn the exhaust three-way ball valve 6 to connect the exhaust duct 4 to the atmosphere. The control system starts the fan 1.

[0032] The gas inside the tent enters the diversion chamber 3 through the diversion control valve 14 and the diversion pipe 13. The gas inside the diversion chamber 3 enters the air intake pipe 5 through the air intake three-way ball valve 7, and then enters the fan 1. Driven by the fan 1, the gas is discharged into the outside atmosphere from the exhaust pipe 1 through the third end of the exhaust three-way ball valve 6, thus realizing the exhaust operation of multiple tents.

[0033] This utility model features a clever structure and convenient operation. The fan 1, distribution chamber 3, exhaust duct 4, intake duct 5, electrical control cabinet 8, and filter 12 are all integrated onto a support frame 9. Casters 10 are installed at the lower end of the support frame 9 for easy movement, allowing it to be moved according to the tent's location. Inflation and deflation are convenient. Multiple tents can be connected simultaneously via the distribution chamber 3 and distribution duct 13, enabling simultaneous inflation or deflation of multiple tents. This results in low operating costs and high work efficiency. Furthermore, this utility model includes a pressure gauge to monitor the pressure values ​​during tent inflation and deflation. Pressure values ​​can also be preset. When the tent reaches the preset inflation pressure, the control system shuts off the fan 1; conversely, when the tent reaches the preset deflation pressure, the control system shuts off the fan 1, achieving rapid inflation and deflation while avoiding energy waste from the fan.

[0034] This utility model, due to the above-mentioned structure, has the advantages of simple structure, ability to inflate and deflate multiple tents at once, low operating cost, and high efficiency.
