Furthermore, the backup power supply device can also supply power to the control module and the 3D printing gas circulation purification device when both the first and second AC power supply detection devices fail to detect an AC signal.

[0018] Figure 1 Schematic diagram of the structure of the 3D printing gas circulation purification system in one embodiment of the present application is shown in FIG. DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.
[0020] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be an element centered therein. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may also be an element centered therein.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.
[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "or / and" as used herein includes any and all combinations of one or more of the relevant listed items.
[0022] See also Figure 1 This embodiment provides a 3D printing gas circulation purification system. The 3D printing gas circulation purification system includes a 3D printing gas circulation purification device, a backup power supply device, and a control module. The control module is communicatively connected to the 3D printing gas circulation purification device. The backup power supply device is electrically connected to the 3D printing gas circulation purification device and the control module. In this embodiment, when the backup power supply device is needed to provide power to the 3D printing gas circulation purification device and the control module, the backup power supply device is electrically connected to the 3D printing gas circulation purification device and the control module. The control module is configured to detect environmental parameters of the 3D printing gas circulation purification device and, based on the detection results, determine whether to perform a deoxygenation operation on the 3D printing gas circulation purification device. The environmental parameters include oxygen content, temperature, or pressure within the 3D printing gas circulation purification device. The 3D printing gas circulation purification device is provided with a first AC power supply detection device, which is communicatively connected to the control module and configured to detect the presence of an AC signal within the 3D printing gas circulation purification device. In this embodiment, the first AC power detection device may be an AC power detection relay, which can detect whether an AC signal is present within the 3D printing gas circulation purification device. For example, when the 3D printing gas circulation purification device is connected to the mains, an AC signal is present within the 3D printing gas circulation purification device. When the 3D printing gas circulation purification device is not connected to the mains or the mains power is cut off, no AC signal is present within the 3D printing gas circulation purification device. The control module may be a control chip, etc.
[0023] Furthermore, when the first AC power detection device fails to detect an AC signal, indicating a mains power outage, causing a power outage in the 3D printing gas circulation purification device, the control module controls the backup power supply device to provide power to the 3D printing gas circulation purification device to ensure normal operation of the 3D printing gas circulation purification device. In other embodiments, the first AC power detection device can also be a detection device other than an AC power detection relay, as long as it can detect the presence of an AC signal within the 3D printing gas circulation purification device. Furthermore, the backup power supply device can be a high-capacity battery to provide DC power to the 3D printing gas circulation purification device.
[0024] The 3D printing gas circulation purification system of the present application can promptly control the backup power supply device to supply power to the 3D printing gas circulation purification device when the first AC power supply detection device detects that there is no AC power signal within the 3D printing gas circulation purification device. This avoids the problem of the 3D printing gas circulation purification device being in a power-off state for a long time, resulting in the inability to timely detect oxygen content and automatically respond to sudden high oxygen levels, thereby affecting 3D printing quality.
[0025] In one embodiment, a second AC power detection device is provided within the control module, the second AC power detection device being communicatively connected to the control module, which is in turn electrically connected to the mains power supply. The second AC power detection device is configured to detect the presence of an AC power signal within the control module. If neither the first nor the second AC power detection device detects an AC power signal, this indicates a mains power outage, necessitating a backup power supply to provide power to the control module and the 3D printing gas circulation and purification device. In this embodiment, the second AC power detection device may also be a relay.
[0026] When the first AC power detection device does not collect an AC signal and the second AC power detection device does not collect an AC signal, it proves that the 3D printing gas circulation purification device and the control module are not connected to the mains, or are connected to the mains, but the mains is out of power. At this time, in order to avoid affecting the 3D printing gas circulation purification device in a power-off state for a long time, resulting in the inability to detect the oxygen content in time and the inability to automatically respond to sudden high oxygen levels, thereby affecting the quality of 3D printing. The backup power supply device promptly provides power to the control module and the 3D printing gas circulation purification device, so that the 3D printing gas circulation purification device can detect the oxygen content in time and automatically respond to sudden high oxygen levels.
[0027] In one embodiment, when the first AC power detection device collects an AC signal and / or the second AC power detection device collects an AC signal, the control module is configured to control the backup power device to be in a closed state.
[0028] In this embodiment, when the first AC power detection device detects an AC signal, it indicates that the 3D printing gas circulation purification device is connected to the mains power supply, and the backup power supply device no longer needs to supply power to the 3D printing gas circulation purification device. Alternatively, when the second AC power detection device detects an AC signal, it indicates that the mains power supply is not interrupted, and the backup power supply device no longer needs to supply power to the 3D printing gas circulation purification device. Therefore, the control module shuts down the backup power supply device from supplying power to the 3D printing gas circulation purification device. This prevents energy waste from the backup power supply device and ensures the normal operation of the 3D printing gas circulation purification device.
[0029] In one embodiment, the 3D printing gas circulation purification system further includes a power supply reminder device. The control module is communicatively connected to the power supply reminder device. When the first AC power detection device does not detect an AC signal and the second AC power detection device detects an AC signal, the control module is configured to detect whether there is an operational anomaly in the first operating state of the 3D printing gas circulation purification device. If an operational anomaly is detected in the first operating state, the control module controls the power supply reminder device to issue an operational anomaly reminder message.
[0030] When the first AC power detection device fails to detect an AC signal and the second AC power detection device detects an AC signal, the control module can detect a first operating state of the 3D printing gas circulation purification device. For example, if the 3D printing gas circulation purification device is damaged and the mains power is not interrupted, there is no need for the backup power supply device to provide power to the 3D printing gas circulation purification device. The control module can control the power supply reminder device to issue an operational abnormality reminder message to alert engineering personnel to promptly check the operating status of the 3D printing gas circulation purification device.
[0031] Similarly, when the first AC power supply detection device collects an AC signal and the second AC power supply detection device does not collect an AC signal, the control module is used to detect whether there is an operation abnormality in the second operating state of the second AC power supply detection device. When it is detected that the second operating state has an operation abnormality, the power supply reminder device is controlled to issue an operation abnormality reminder information.
[0032] In one embodiment, the backup power supply device includes a backup power supply module and a power generation module, the power generation module is used to charge the backup power supply module, and the backup power supply module is used to provide power to the control module and the 3D printing gas circulation purification device.
[0033] In this embodiment, the backup power module is a battery module, and the power generation module is a generator. The generator can be a diesel generator, a solar generator, a wind generator, or the like. Alternatively, in other embodiments, the power generation module can be a mains power device that charges the battery module.
[0034] In one embodiment, the environmental value includes a first oxygen value. The 3D printing gas circulation purification device includes a gas purification chamber, an oxygen meter, and an alarm device, wherein a control module is communicatively connected to the oxygen meter and the alarm device. The oxygen meter is configured to collect the first oxygen value within the gas purification chamber and transmit the first oxygen value to the control module. The control module is configured to control the alarm device to issue an alarm when it detects that the first oxygen value is greater than a preset oxygen threshold.
[0035] In this embodiment, the oxygen meter can be installed inside or outside the gas purification chamber. When the oxygen meter is installed outside the gas purification chamber, the detection probe of the oxygen meter needs to extend into the gas purification chamber to detect the oxygen content in the gas purification chamber. The alarm device can be an audible or visual alarm, such as a buzzer, a flashing light, etc.
[0036] When the first oxygen value exceeds the preset oxygen threshold, it indicates that the oxygen content in the gas purification chamber is too high. To prevent oxidation of the printed material, which could affect the print quality, emergency measures are required. For example, an alarm device may sound an alarm to alert the printer to the abnormal oxygen content in the gas purification chamber. The specific value of the preset oxygen threshold can be set based on the print quality requirements, and this application does not specifically limit the value of the preset oxygen threshold.
[0037] In one embodiment, the environmental value includes a first temperature value. The 3D printing gas circulation purification device includes a gas purification chamber, a temperature detector, and an alarm device, with the control module being communicatively connected to the temperature detector. The temperature detector is configured to collect a first temperature value within the gas purification chamber and transmit the first temperature value to the control module. The control module is configured to control the alarm device to issue an alarm when it detects that the first temperature value exceeds a preset temperature threshold.
[0038] Similarly, the temperature detector can be installed inside the gas purification chamber or outside the gas purification chamber. When the temperature detector is installed outside the gas purification chamber, the detection probe of the temperature detector needs to be extended into the gas purification chamber to detect the temperature value inside the gas purification chamber.
[0039] When the first temperature value exceeds a preset temperature threshold, it indicates that the temperature within the gas purification chamber is too high. To prevent the printed material from failing to solidify and thus affecting the print quality, emergency measures may be necessary. For example, an alarm device may sound an alarm to alert the printer to the abnormal temperature within the gas purification chamber. The specific value of the preset temperature threshold can be set based on the print quality requirements, and this application does not specifically limit the value of the preset temperature threshold.
[0040] It should be noted that when the control module detects whether the first oxygen value is greater than the preset oxygen threshold, or the first temperature value is greater than the preset temperature threshold, the control alarm device issues an alarm reminder to remind the printing personnel to pay attention to the status of the 3D printing gas circulation purification device in time.
[0041] In one embodiment, the environmental value also includes a pressure value. The 3D printing gas circulation purification device also includes an indoor pressure detector, and the control module is communicatively connected to the indoor pressure detector. In this embodiment, the indoor pressure detector is a medium-efficiency pressure gauge. The medium-efficiency pressure gauge is used to detect the pressure value in the gas purification chamber and send the pressure value to the control module. The control module is used to control the 3D printing gas circulation purification device to perform a deoxygenation operation when it detects that the pressure value is greater than a preset pressure threshold. The specific value of the preset pressure threshold can also be set according to the printing quality requirements, and this application does not specifically limit the value of the preset pressure threshold.
[0042] When the control module detects whether the first oxygen value is greater than a preset oxygen threshold, or the first temperature value is greater than a preset temperature threshold, the control module controls the alarm device to sound an alarm. Simultaneously, when the control module detects that the pressure value within the gas purification chamber is greater than a preset pressure threshold, it indicates that the pressure within the gas purification chamber is high enough and that the gas within the gas purification chamber needs to be circulated and purified. Therefore, the 3D printing gas circulation and purification device is controlled to perform a deoxygenation operation.
[0043] In one embodiment, the 3D printing gas circulation purification device further includes a driving gas pressure detector and an exhaust device, and the control module is communicatively connected to the driving gas pressure detector and the exhaust device. The driving gas pressure detector is a compressed gas pressure gauge. The exhaust device is used to extract gas from the gas purification chamber and discharge it to the outside of the 3D printing gas circulation purification device. The driving gas pressure detector is used to collect the driving gas pressure value of the exhaust device and transmit the driving gas pressure value to the control module. The control module determines whether to open or close the exhaust device based on the driving gas pressure value.
[0044] In this embodiment, when the 3D printing gas circulation purification device is required to perform deoxygenation, the exhaust device exhausts the gas within the gas purification chamber to facilitate the subsequent filling of the gas purification chamber with shielding gas to reduce the oxygen content. Simultaneously, an indoor pressure detector is used to monitor the pressure within the gas purification chamber until the pressure within the gas purification chamber is less than or equal to a preset pressure threshold. The shielding gas is an inert gas.
[0045] In one embodiment, the 3D printing gas circulation and purification device further includes a shielding gas pressure detector and a shielding gas supply device, and the control module is communicatively connected to the shielding gas pressure detector and the shielding gas supply device. The shielding gas pressure detector can be a shielding gas pressure gauge. The shielding gas supply device is used to supply inert gas to the gas purification chamber. The shielding gas pressure detector is used to collect the pressure value of the inert gas output by the shielding gas supply device and transmit the inert gas pressure value to the control module. The control module determines whether to open or close the shielding gas supply device based on the inert gas pressure value.
[0046] In this embodiment, when the 3D printing gas circulation purification device is required to perform deoxygenation and the exhaust device has completed exhausting the gas in the gas purification chamber, the control module controls the shielding gas supply device to input inert gas into the gas purification chamber to reduce the oxygen content. Simultaneously, a shielding gas pressure detector detects the pressure of the inert gas output by the shielding gas supply device to adjust the inert gas content input into the gas purification chamber, thereby preventing excessive or insufficient inert gas from affecting printing quality.
[0047] It should be noted that when flushing inert gas into the gas purification chamber, an oxygen meter is required to monitor the oxygen content in the gas purification chamber in real time to avoid the situation where the oxygen content is too low and causes poor printing quality. If the control module detects that the oxygen content in the gas purification chamber is greater than the preset oxygen threshold, the shielding gas supply device is controlled to continue to supply inert gas to the gas purification chamber until the oxygen content in the gas purification chamber is less than or equal to the preset oxygen threshold, at which point the shielding gas supply device is controlled to be closed.
[0048] In one embodiment, when the 3D printing gas circulation purification device performs a deoxygenation operation, the oxygen meter is used to collect a second oxygen value in the gas purification chamber and send the second oxygen value to the control module, or the temperature detector is used to collect a second temperature value in the gas purification chamber and send the second temperature value to the control module. When the control module detects that the second oxygen value is less than or equal to a preset oxygen threshold, or when the second temperature value is less than or equal to a preset temperature threshold, the control module controls the protective gas supply device and the exhaust device to be in a closed state after a preset time. Among them, the preset time can be set to 30 seconds, 1 minute, etc., and can be set according to the actual requirements of the gas in the circulating purification gas purification chamber.
[0049] In this embodiment, an exhaust device is used to extract gas from the gas purification chamber and discharge it to the outside of the 3D printing gas circulation purification device, and a shielding gas supply device is used to supply inert gas into the gas purification chamber to reduce the oxygen content in the gas purification chamber, thereby achieving the purpose of purifying the gas in the gas purification chamber. When the control module detects that the second oxygen value is less than or equal to a preset oxygen threshold, or when the control module detects that the second temperature value is less than or equal to a preset temperature threshold, it is also necessary to control the exhaust device to continue to extract gas from the gas purification chamber and discharge it to the outside of the 3D printing gas circulation purification device, and the shielding gas supply device to continue to supply inert gas into the gas purification chamber for a preset period of time to ensure that the gas in the gas purification chamber is thoroughly purified.
[0050] Figure 1 In the illustrated 3D printing gas circulation purification system, when the first AC power supply detection device fails to detect an AC signal, it indicates a power outage in the 3D printing gas circulation purification device. In this case, the control module controls the backup power supply device to supply power to the 3D printing gas circulation purification device. Furthermore, the backup power supply device can also supply power to the control module and the 3D printing gas circulation purification device when both the first AC power supply detection device and the second AC power supply detection device fail to detect an AC signal. This dual detection prevents the backup power supply device from being mistakenly controlled to supply power to the 3D printing gas circulation purification device due to damage, preventing it from connecting to the mains (in which case the control module is electrically connected to the mains), or when the control module fails to connect to the mains (in which case the 3D printing gas circulation purification device is electrically connected to the mains), thereby wasting energy from the backup power supply device. After the backup power supply provides power to the 3D printing gas circulation purification device and control module, the control module can determine whether to perform deoxygenation operations on the 3D printing gas circulation purification device based on the detected temperature, oxygen level, and pressure in the gas purification chamber. This avoids the problem of being unable to timely detect oxygen content and high temperature in the gas purification chamber in the event of a power outage during the 3D printing process, and unable to automatically respond to sudden high oxygen or high temperature conditions, thereby affecting the quality of 3D printing.
[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not limiting. Although the present application has been described in detail with reference to the above embodiments, ordinary technicians in this field should understand that the technical solution of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
