[0026] The present invention will be further described in detail below in conjunction with the embodiments. The following embodiments are intended to explain the present invention, but the present invention is not limited to the following embodiments.

[0027] Example 1

[0028] like Figure 1As shown, an inflation and deflation device includes a power generation device 1, an inflation and deflation air pressure control device 2 and an inflation target 3. The inflation and deflation air pipe 4 of the inflation and deflation air pressure control device 2 is detachably connected to the inflation port of the inflation target 3, and an air pressure detection pipe 5 is detachably connected between the inflation and deflation air pressure control device 2 and the inflation target 3. The power cord 6 of the power generation device 1 is connected to the inflation and deflation air pressure control device 2, and a data transmission cable 7 is also provided between the inflation and deflation air pressure control device 2 and the power generation device 1.

[0029] Among them, the inflatable target 3 referred to in this embodiment refers to an inflatable product that needs to be inflated, which can be classified into different categories according to its purpose and shape, including military simulation air models, inflatable advertising balloons, large multi-functional inflatable tents and other inflatable products; and the power generation device 1 in this embodiment can be a diesel generator, which provides power support to the charging and discharging air pressure control device 2 through the power cord 6, and the charging and discharging air pressure control device 2 can also send start or stop instructions to the diesel generator through the data transmission cable 7.

[0030] In this embodiment, the inflatable target 3 is a large multifunctional inflatable tent as an example. When it needs to be inflated, the staff will carry the inflation and deflation air pressure control device 2 connected to the power generation device 1 to the inflation site, and then seal the inflation and deflation pipe 4 of the inflation and deflation air pressure control device 2 with the inflation port of the inflatable target 3.

[0031] After completing the sealed installation connection, the inflation and deflation pressure control device 2 sends a start-up command to the diesel generator through the data transmission cable 7. The diesel generator starts after receiving the command, thereby providing the inflation and deflation pressure control device 2 with electrical energy during operation. After ensuring that the inflation and deflation pressure control device 2 has continuous and stable electrical energy for operation, the inflation and deflation pressure control device 2 begins to inflate the large multifunctional inflatable tent.

[0032] This embodiment avoids the problem of the existing charging and discharging air pressure control device 2 needing to find a power supply or use a power strip to power it when working, by providing the power generation device 1, thereby reducing the requirements for the use environment of the charging and discharging air pressure control device 2.

[0033] When the large multifunctional inflatable tent needs to be folded up and deflated, the inflation and deflation pressure control device 2 starts the air extraction operation. When there is no gas in the large multifunctional inflatable tent, the inflation and deflation pressure control device 2 suspends the air extraction operation and sends a stop command to the diesel generator. After receiving the command, the diesel generator stops generating electricity.

[0034] Specifically, such as Figure 2 and Figure 3As shown, the inflation and deflation air pressure control device 2 includes a shell 8, a control component 9, an inflation and deflation pipe 4, an inflation component 10 and a deflation component 11. The control component 9, the inflation component 10 and the deflation component 11 are all fixedly installed in the shell 8. The control component 9 is electrically connected to the inflation component 10 and the deflation component 11. The pump heads of the inflation component 10 and the deflation component 11 are connected to the inflation and deflation pipe 4 through a three-way component 12. A first air pressure detection component 13 is also provided between the three-way component 12 and the control component 9.

[0035] When the inflation and deflation pressure control device 2 inflates the large multifunctional inflatable tent, the inflation component 10 starts to output the inflation gas and transmits the gas into the large multifunctional inflatable tent through the inflation and deflation pipe 4; when the large multifunctional inflatable tent needs to be folded up and deflated, the deflation component 11 starts to extract the gas in the large multifunctional inflatable tent through the inflation and deflation pipe 4, thereby achieving air extraction.

[0036] More specifically, if Figure 2 As shown, the inflation component 10 includes an inflation pump 14 and a first electric ball valve 15, the pump head of the inflation pump 14 is sealedly connected to one end of the first electric ball valve 15, and the other end of the first electric ball valve 15 is sealedly connected to the inflation target 3 through the three-way component 12; the deflation component 11 includes an inflation pump 17 and a second electric ball valve 18, the pump head of the deflation pump 17 is sealedly connected to one end of the second electric ball valve 18, and the other end of the second electric ball valve 18 is sealedly connected to the inflation target 3 through the three-way component 12.

[0037] like Figure 2 As shown, the three-way assembly 12 includes a Y-type tee 19 and a T-type tee 20. The first port of the Y-type tee 19 is connected to the end of the first electric ball valve 15 away from the inflation pump 14, the second port of the Y-type tee 19 is connected to the end of the second electric ball valve 18 away from the deflation pump 17, the third port of the Y-type tee 19 is connected to the first port of the T-type tee 20, the second port of the T-type tee 20 is connected to the inflation and deflation pipe 4, and the third port of the T-type tee 20 is connected to the first air pressure detection assembly 13.

[0038] When the inflation and deflation air pressure control device 2 inflates the large multifunctional inflatable tent, the first electric ball valve 15 is opened, the air pump 14 is started, and the compressed air passes through the first electric ball valve 15 and enters the first port of the Y-type tee 19. Then, the compressed air enters the T-type tee 20 through the third port of the Y-type tee 19, and is transmitted to the inflation and deflation pipe 4 through the second port of the T-type tee 20, and then the large multifunctional inflatable tent is inflated through the inflation and deflation pipe 4.

[0039] When the large multifunctional inflatable tent needs to be folded and deflated, the air pump 14 is paused and the first electric ball valve 15 is closed to stop the inflation action.

[0040] After the first electric ball valve 15 is closed, the second electric ball valve 18 is controlled to open and the deflation pump 17 is started. At this time, the compressed air in the large multifunctional inflatable tent will be extracted through the inflation and deflation pipe 4, and the extracted compressed air will be transmitted to the first port of the T-shaped tee 20 through the second port of the T-shaped tee 20, and then transmitted to the third port of the Y-shaped tee 19, and then the compressed air will be extracted by the deflation pump 17 through the second port of the Y-shaped tee 19.

[0041] On the other hand, Figure 4 and Figure 5 As shown, the first air pressure detection component 13 includes an air pressure sensor 21, which is mounted on the control circuit board 23 of the control component 9, and the air pressure detection pipe 5 of the air pressure sensor 21 is connected to the third port of the T-shaped tee 20; the inflation and deflation device of this embodiment also includes an air pressure sensor 22, which is mounted on the control circuit board 23 of the control component 9, and the air pressure detection pipe 5 of the air pressure sensor 22 is sealed and connected to the inflation target 3.

[0042] Since the air pressure in the inflatable target 3 has a maximum air pressure tolerance value and a minimum air pressure tolerance value, when the air pressure exceeds the maximum air pressure tolerance value, the inflatable target 3 will have a risk of exploding, and when it is less than the minimum air pressure tolerance value, the inflatable target 3 will have a risk of collapsing. Therefore, it is very important to detect the air pressure in the inflatable target 3.

[0043] Furthermore, in order to ensure that the large-scale multifunctional inflatable tent is not filled with excessive gas, thereby ensuring the safety of the air pressure in the large-scale multifunctional inflatable tent, this embodiment sets an air pressure sensor 21 and connects the air pressure sensor 21 to the third port of the T-shaped three-way 20 to realize the detection of the inflation pressure during the inflation process of the air pump 14; on the other hand, this embodiment also sets an air pressure sensor 22 and connects the air pressure sensor 22 to the sealed and detachable connection of the large-scale multifunctional inflatable tent to realize the detection of the air pressure in the large-scale multifunctional inflatable tent, and then ensures the air pressure safety of the large-scale multifunctional inflatable tent through double air pressure detection.

[0044] In this embodiment, if Figure 5As shown, the control component 9 is a main control mechanism with a control function, and the control component 9 has a built-in power supply. The control component 9 includes a control box 24, a control circuit board 23 and a touch display screen 25. The control circuit board 23 is fixedly installed in the control box 24, and the air pressure sensor 1 21 and the air pressure sensor 2 22 are both installed on the control circuit board 23. The touch display screen 25 is embedded in the control box 24 for realizing human-computer interaction, such as viewing the air pressure values ​​detected by the air pressure sensor 1 21 and the air pressure sensor 2 22; displaying the inflation upper limit value, inflation lower limit value, inflation target value, and deflation lower limit value of the inflatable target 3, etc. A control chip is also provided on the control circuit board 23, and the control chip is a prior art, so it will not be further described.

[0045] On the other hand, when the built-in power supply of the control component 9 is low, the power generation device 1 of this embodiment can automatically start to store energy for the built-in power supply.

[0046] It should be noted that the start and stop of the power generation device 1, the inflation pump 14, the deflation pump 17, the first electric ball valve 15, the second electric ball valve 18, the air pressure sensor 1 21, and the air pressure sensor 2 22, as well as the air pressure detection of the air pressure sensor 1 21 and the air pressure sensor 2 22 in this embodiment are all controlled by the program set in the control component 9, and this control program is all existing technology, so it will not be further described here.

[0047] Example 2

[0048] An inflation and deflation system includes the inflation and deflation device as described in Example 1, and also includes a terminal device, which is communicatively connected to the control component 9.

[0049] The terminal device may be a mobile phone, a computer, a server, etc. In this embodiment, the terminal device is taken as a mobile phone as an example to illustrate the communication process with the control component 9.

[0050] Specifically, the control component 9 can realize communication connection with the mobile phone, and the mobile phone can send control instructions to the cloud. The cloud sends the control instructions to the control component 9. After receiving the control instructions, the control component 9 controls the inflation and deflation pressure control device 2 to perform inflation or deflation operations. Then the control component 9 will return the instructions of the operation completion to the cloud, and the cloud will send the returned instructions to the mobile phone. It should be noted that the instruction transmission between the mobile phone and the control component 9 mentioned in this embodiment is an existing technology, so it will not be described in detail.

[0051] On the other hand, the mobile phone is also installed with a small program or APP corresponding to the inflation and deflation pressure control device 2 (this is the existing technology). The inflation upper limit value, inflation lower limit value, inflation target value, and deflation lower limit value in the touch display screen 25 can all be uploaded to the cloud and synchronized to the small program or APP of the mobile phone, thereby realizing data viewing on the device terminal. At the same time, the user can also set the above data through the small program or APP, and after setting, synchronize it to the touch display screen 25 of the control component 9 through the cloud for display. On the other hand, in the small program or APP of the mobile phone, the air pressure value of the current inflation report and the inflation and deflation history data of the inflation target 3 can also be viewed, thereby achieving the effect of remote control.

[0052] Furthermore, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may vary. Any equivalent or simple variations based on the structure, features, and principles described in this utility model are included within the scope of protection of this utility model. Those skilled in the art of the present invention may make various modifications, additions, or substitutions to the described specific embodiments, and these modifications, as long as they do not deviate from the structure of this utility model or exceed the scope defined by these claims, shall fall within the scope of protection of this utility model.
