Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen filling equipment, in particular to a nitrogen filling joint and a nitrogen filling device. Background Art

[0002] In the manufacturing and maintenance of refrigeration equipment such as air conditioners and refrigerators, nitrogen filling is an important step to protect the cleanliness of the refrigeration system and prevent oxidation of refrigeration system components. During the nitrogen filling process, workers usually use a nitrogen filling connector to connect with the nitrogen filling port of the refrigeration system of the equipment, for example, connect the nitrogen filling connector to the nitrogen filling port of the refrigeration system of the air conditioner, and start nitrogen filling after ensuring that the connection is firm and leak-free. However, existing nitrogen filling connectors are usually connected to the nitrogen filling port of the refrigeration system using a sleeve, and the connection between the sleeve and the connector body is fixed and cannot be turned. This structure means that during the nitrogen filling process, workers need to manually rotate the equipment to be nitrogen-filled so that the sleeve of the nitrogen filling connector can match the nitrogen filling port. This method greatly increases the burden on workers, especially for large-scale refrigeration equipment. The labor intensity of rotating the equipment is extremely high, and there is a lot of wasted movement, which seriously affects production efficiency and also poses certain safety hazards.

[0003] Therefore, it is necessary to improve the existing nitrogen filling joint to overcome the defects of the prior art. Utility Model Content

[0004] In order to overcome the problems existing in the related art, one of the purposes of the present invention is to provide a nitrogen filling joint, the connector of which can be rotated on the nitrogen filling body, so that the position and angle of the gas nozzle can be adjusted, so that the gas nozzle can be connected to the equipment to be nitrogen-filled at different positions, which helps to improve the nitrogen filling efficiency of the equipment and reduce production costs.

[0005] A nitrogen filling joint, comprising:

[0006] A nitrogen filling body, wherein a nitrogen filling channel is provided in the nitrogen filling body;

[0007] A connector is provided at one end of the nitrogen filling body, and the connector is rotatably connected to the nitrogen filling body; a gas nozzle is provided at one side of the connector, and the gas nozzle is communicated with the nitrogen filling channel.

[0008] The connector of the nitrogen charging connector can rotate freely on the nitrogen charging body, allowing the position and angle of the gas nozzle to be flexibly adjusted. This design can adapt to various positions and angles of the nitrogen-filled equipment, greatly improving the flexibility and applicability of the equipment.

[0009] Since the gas nozzle can be easily aligned with the nitrogen filling equipment, there is no need to frequently adjust the equipment position or find the right connector, which saves a lot of time. This design significantly improves the efficiency of nitrogen filling, making the filling process faster and smoother.

[0010] In addition, there is no need for staff to adjust the position of the equipment to be filled with nitrogen, which can greatly reduce the workload of operators and improve work efficiency.

[0011] In a preferred technical solution of the present invention, a mounting groove is provided on one side of the connector, a hinge seat is provided in the mounting groove, and one end of the nitrogen filling body is hinged to the hinge seat;

[0012] A connecting pipe is provided at one end of the nitrogen filling body, and the gas nozzle is connected with the nitrogen filling channel through the connecting pipe.

[0013] The connecting pipe connects the gas nozzle to the nitrogen charging channel, ensuring that nitrogen can flow smoothly from the charging channel through the connecting pipe and ultimately be output through the gas nozzle to the equipment to be charged. The design of the mounting groove and hinge seat allows the connector to rotate along the hinge axis of the nitrogen charging body's hinge seat. The connection between the nitrogen charging body and the connector is stable and not prone to loosening or falling off, thus ensuring the safety and stability of the nitrogen charging process.

[0014] In a preferred technical solution of the present invention, a mounting groove is provided on one side of the connector, a ball joint seat is provided in the mounting groove; a connecting ball is provided on one end of the nitrogen filling body, and the connecting ball is provided in the ball joint seat;

[0015] A connecting pipe is provided at one end of the nitrogen filling body, and the connecting pipe passes through the ball joint seat and is connected with the gas nozzle.

[0016] The matching mode of the connecting ball and the ball joint seat enables the connector to achieve 360-degree free rotation on the nitrogen charging body, thereby greatly improving the flexibility and adjustment range of the joint, so that the gas nozzle can be easily connected to the nitrogen charging equipment at different positions and angles.

[0017] In a preferred technical solution of the present invention, a connecting hole is provided on one side of the connecting head, a connecting plate is provided on the gas nozzle, and a mounting hole is provided on the connecting plate, and the mounting hole corresponds to the connecting hole;

[0018] The mounting hole and the connecting hole are connected by bolts so that the gas nozzle is fixed on the connecting head.

[0019] During installation, align the mounting hole on the connecting plate of the gas nozzle with the connecting hole of the connector, and then tightly connect the two together with bolts so that the gas nozzle is firmly fixed on the connector.

[0020] Bolting the connecting plate of the gas nozzle to the connecting hole of the connector makes the connection between the gas nozzle and the connector more stable and less likely to loosen or fall off, thereby improving safety in use. Because the connecting hole and the mounting hole are of standard size, the gas nozzle and connector fixing structure of the present application can be applied to a variety of gas nozzles and connectors of different specifications and models, enhancing its versatility and applicability.

[0021] In a preferred technical solution of the present invention, the nitrogen filling body includes a first body and a second body, one end of the second body is sleeved on the first body, and the other end opposite thereto is provided with the connector;

[0022] The nitrogen filling channel passes through the first body and the second body and extends into the connecting head.

[0023] The split design allows each part of the nitrogen charging unit to be independently manufactured and tested, thereby improving the stability and reliability of the overall structure. If a part fails or is damaged, it can be repaired or replaced independently without having to replace the entire nitrogen charging connector, reducing maintenance costs.

[0024] In a preferred technical solution of the present invention, a buffer spring is provided between the first body and the second body, one end of the buffer spring abuts against the first body, and the other end thereof abuts against the second body.

[0025] When the nitrogen charging connector is subjected to external forces or accidental collisions, the buffer spring acts as a buffer, reducing damage to the connector's internal structure. Furthermore, the buffer spring can adjust the relative position between the first and second bodies to a certain extent to accommodate nitrogen-charged equipment of varying lengths, increasing the connector's flexibility and applicability.

[0026] In a preferred technical solution of the present invention, a locking structure is provided on the first body, and the locking structure includes a threaded segment and a nut provided on the first body. Two nuts are provided, and both nuts are threadedly connected to the threaded segment.

[0027] By rotating the nuts, their positions on the threaded section can be adjusted. In practical applications, when it is necessary to fix the position of the first body, this can be achieved by tightening the two nuts, thereby preventing the first body from moving or becoming loose during use.

[0028] The second object of the present utility model is to provide a nitrogen charging device, comprising a driving device and a mounting plate, wherein the mounting plate is fixed to the output end of the driving device, and the nitrogen charging connector as described above is provided on the mounting plate.

[0029] In a preferred technical solution of the present invention, a clamping groove is provided on the mounting plate, two of the clamping grooves are provided, and the two clamping grooves are provided on opposite sides of the mounting plate, and the two clamping grooves are located on the same straight line; the nitrogen filling connector is clamped on the clamping groove.

[0030] The locking structure is connected to the mounting slot, so that the position of the nitrogen charging connector can be adjusted to meet different usage requirements.

[0031] In a preferred technical solution of the present invention, the nitrogen filling device further includes an air supply device and a controller, the air supply device is provided with an air valve, and the air valve is communicated with the nitrogen filling channel;

[0032] The controller is provided with a timer, and the timer and the gas valve are both electrically connected to the controller.

[0033] In actual use, the device uses a controller that allows the user to preset the nitrogen filling time. Once the preset time is reached, the controller will control the gas valve to close through an electrical signal, automatically ending the nitrogen filling process. This automated control method not only improves operational efficiency but also avoids the problem of substandard nitrogen filling due to human error.

[0034] The beneficial effects of the utility model are:

[0035] The utility model provides a nitrogen filling connector, which includes a nitrogen filling body, and a nitrogen filling channel is provided in the nitrogen filling body. A connector is provided at one end of the nitrogen filling body, and the connector is rotatably connected to the nitrogen filling body; a gas nozzle is provided on one side of the connector, and the gas nozzle is connected to the nitrogen filling channel. When the nitrogen filling connector is in use, it is only necessary to rotate the connector of the nitrogen filling connector to an appropriate angle, align the gas nozzle with the interface of the device to be nitrogen-filled, and connect the gas nozzle to the interface. Then, the nitrogen supply is turned on, and the nitrogen will enter the gas nozzle through the nitrogen filling channel and be transported to the device to be nitrogen-filled. Since the connector can be flexibly rotated, the gas nozzle can be easily connected to the devices to be nitrogen-filled at different positions and angles. During the nitrogen filling process, there is no need to frequently adjust the position of the equipment or find a suitable connector, thereby saving a lot of time. In addition, the operator only needs to gently rotate the connector to achieve the connection between the gas nozzle and the device to be nitrogen-filled, without the need for a complicated adjustment process. This simple operation method greatly reduces the workload of the operator, improves work efficiency, and can also reduce the possibility of damage during the equipment position adjustment process.

[0036] The present application also provides a nitrogen filling device including the above-mentioned nitrogen filling connector. The device can drive the nitrogen filling connector to move through a driving device to achieve automatic docking of the nitrogen filling connector with the equipment to be nitrogen-filled, thereby realizing automatic nitrogen filling of the equipment, which can greatly reduce the labor cost of nitrogen filling of the equipment.

[0046] The following describes preferred embodiments of the present invention in more detail with reference to the accompanying drawings. Although preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0047] In the manufacturing and maintenance of refrigeration equipment such as air conditioners and refrigerators, nitrogen filling is an important step to protect the cleanliness of the refrigeration system and prevent oxidation of refrigeration system components. During the nitrogen filling process, workers usually use a nitrogen filling connector to connect with the nitrogen filling port of the refrigeration system of the equipment, for example, connect the nitrogen filling connector to the nitrogen filling port of the refrigeration system of the air conditioner, and start nitrogen filling after ensuring that the connection is firm and leak-free. However, existing nitrogen filling connectors are usually connected to the nitrogen filling port of the refrigeration system using a sleeve, and the connection between the sleeve and the connector body is fixed and cannot be turned. This structure means that during the nitrogen filling process, workers need to manually rotate the equipment to be nitrogen-filled so that the sleeve of the nitrogen filling connector can match the nitrogen filling port. This method greatly increases the burden on workers, especially for large-scale refrigeration equipment. The labor intensity of rotating the equipment is extremely high, and there is a lot of wasted movement, which seriously affects production efficiency and also poses certain safety hazards.

[0048] Based on this, the present application provides a nitrogen filling joint.

[0049] Example 1

[0050] like Figure 1-Figure 7 As shown, this embodiment provides a nitrogen filling connector, including:

[0051] A nitrogen filling body 1 is provided with a nitrogen filling channel;

[0052] A connector 2 is provided at one end of the nitrogen filling body 1 , and the connector 2 is rotatably connected to the nitrogen filling body 1 ; a gas nozzle 3 is provided on one side of the connector 2 , and the gas nozzle 3 is communicated with the nitrogen filling channel.

[0053] Specifically, the nitrogen filling body 1 is cylindrical and made of stainless steel to ensure durability and corrosion resistance. A nitrogen filling channel is located within the body 1, with a diameter of 5 mm to accommodate varying gas flow rates. In this embodiment, the connector 2 is rotatably connected to the body 1 via precision bearings, ensuring that the connector 2 can rotate freely on the body 1, with an angle adjustment range of 0 to 360 degrees.

[0054] During use, the operator can manually rotate the connector 2 and adjust the gas nozzle 3 to the optimal position according to the interface position and angle of the device to be filled with nitrogen. By opening the valve, nitrogen can enter the device to be filled with nitrogen through the gas nozzle 3.

[0055] The connector 2 of the nitrogen filling joint can rotate freely on the nitrogen filling body 1, so that the position and angle of the gas nozzle 3 can be flexibly adjusted. This design can adapt to various positions and angles of nitrogen-filled equipment, greatly improving the flexibility and applicability of the equipment.

[0056] Because the gas nozzle 3 easily aligns with the equipment being filled, there's no need to frequently adjust the equipment's position or search for the right connector, saving significant time. This design significantly improves nitrogen filling efficiency, making the process faster and smoother. Furthermore, there's no need for operators to adjust the equipment's position, significantly reducing their workload and improving efficiency.

[0057] In a more preferred embodiment of this embodiment, the main body of the gas nozzle 3 of the present application is generally made of corrosion-resistant and high-temperature resistant materials, such as stainless steel or aluminum alloy, to ensure stability and durability in various environments. The gas nozzle 3 can be equipped with an adjustment mechanism, such as a valve or knob, for controlling the flow and pressure of the gas. This allows the operator to adjust the gas output as needed to adapt to different nitrogen filling requirements. In addition, a guide structure, such as a guide sleeve or a guide groove, is provided on the gas nozzle 3 to ensure that the gas nozzle 3 can be accurately aligned when connected to the equipment to be nitrogen-filled, thereby reducing the risk of gas leakage.

[0058] Example 2

[0059] This embodiment is improved on the basis of the embodiment 1, and the connection structure between the connector 2 and the nitrogen filling body 1 is described in detail.

[0060] like Figure 1-Figure 7 As shown, in this embodiment, a mounting groove 22 is provided on one side of the connector 2, a hinge seat 23 is provided in the mounting groove 22, and one end of the nitrogen filling body 1 is hinged to the hinge seat 23;

[0061] A connecting pipe 15 is provided at one end of the nitrogen filling body 1 , and the gas nozzle 3 is connected to the nitrogen filling channel through the connecting pipe 15 .

[0062] The depth and width of the mounting groove 22 are customized according to the size of the connector 2 to ensure that the connector 2 can be firmly connected to the nitrogen filling body 1 .

[0063] Gas nozzle 3 communicates with the nitrogen charging channel via a connecting tube 15. The length and diameter of connecting tube 15 are designed based on the size of gas nozzle 3 and the requirements of the nitrogen charging channel to ensure continuous and stable gas flow. Connecting tube 15 ensures that nitrogen can flow smoothly from the nitrogen charging channel through connecting tube 15 and ultimately be delivered through gas nozzle 3 to the equipment to be charged.

[0064] The design of the mounting slot 22 and hinged seat 23 allows the connector 2 to rotate freely on the nitrogen charging body 1, allowing the gas nozzle 3 to be easily adjusted to the optimal position for the equipment to be nitrogen-charged, thereby improving the flexibility and adaptability of the nitrogen charging process. Furthermore, the connection between the nitrogen charging body 1 and the connector 2 is stable and not prone to loosening or falling off, thus ensuring the safety and stability of the nitrogen charging process.

[0065] Example 3

[0066] This embodiment is improved on the basis of the embodiment 1, and the connection structure between the connector 2 and the nitrogen filling body 1 is described in detail.

[0067] like Figure 1-Figure 7 As shown, the connection structure between the connector 2 and the nitrogen filling body 1 of this embodiment is different from that of the embodiment 2.

[0068] In this embodiment, a mounting groove 22 is provided on one side of the connector 2, and a ball joint seat 23 is provided in the mounting groove 22; a connecting ball 14 is provided on one end of the nitrogen filling body 1, and the connecting ball 14 is provided in the ball joint seat 23;

[0069] A connecting pipe 15 is provided at one end of the nitrogen filling body 1 , and the connecting pipe 15 passes through the ball joint seat 23 and is connected to the gas nozzle 3 .

[0070] In this embodiment, the connecting ball 14 cooperates with the ball joint seat 23 to allow the connector 2 to rotate 360 degrees on the nitrogen charging body 1. This allows for full adjustment of the connector 2, greatly improving the flexibility and adjustment range of the joint, allowing the gas nozzle 3 to be easily connected to the equipment to be charged at different positions and angles.

[0071] It should be noted that the connecting pipe 15 in this embodiment may have the same structure as the connecting pipe 15 in Example 2. The connecting pipe 15 is preferably implemented as a hose. In another embodiment, the connecting pipe 15 may also be a bellows.

[0072] Example 4

[0073] This embodiment is improved on the basis of the embodiment 1, and the matching manner of the gas nozzle 3 and the connecting head 2 is described in detail.

[0074] like Figure 1-Figure 7 As shown, in the embodiment, a connecting hole 21 is provided on one side of the connecting head 2, a connecting plate 31 is provided on the gas nozzle 3, and a mounting hole 32 is provided on the connecting plate 31, and the mounting hole 32 corresponds to the connecting hole 21;

[0075] The mounting hole 32 and the connecting hole 21 are connected by bolts, so that the gas nozzle 3 is fixed on the connecting head 2 .

[0076] During installation, align the mounting hole 32 on the connecting plate 31 of the gas nozzle 3 with the connecting hole 21 of the connector 2 , and then tightly connect the two together with bolts, so that the gas nozzle 3 is firmly fixed on the connector 2 .

[0077] Bolting the connecting plate 31 of the gas nozzle 3 to the connecting hole 21 of the connector 2 makes the connection between the gas nozzle 3 and the connector 2 more stable, less likely to loosen or fall off, and improves safety. Because the connecting hole 21 and the mounting hole 32 are both standard sizes, the gas nozzle 3 and connector 2 fixing structure of the present application can be used with a variety of gas nozzles 3 and connectors 2 of different specifications and models, enhancing its versatility and applicability.

[0078] At the same time, the bolt connection also facilitates the disassembly and replacement of the gas nozzle 3, providing convenience for future maintenance and care.

[0079] Furthermore, it should be noted that after the gas nozzle 3 is secured to the connector 2, it is connected to the nitrogen filling channel. This means that nitrogen can flow smoothly from the nitrogen filling channel into the connecting hole 21 and then be discharged through the gas nozzle 3. This design ensures the continuity and stability of nitrogen delivery, providing a strong guarantee for the nitrogen filling operation of the refrigeration equipment. Furthermore, it is necessary to ensure the airtightness between the gas nozzle 3 and the nitrogen filling channel. For example, a rubber ring can be installed between the gas nozzle 3 and the nitrogen filling channel to improve the airtightness between the two.

[0080] Example 5

[0081] This embodiment is improved on the basis of the embodiment 1, and the structure of the nitrogen filling body 1 is described in detail.

[0082] like Figure 1-Figure 7 As shown, in this embodiment, the nitrogen filling body 1 includes a first body 11 and a second body 12, one end of the second body 12 is sleeved on the first body 11, and the other end opposite thereto is provided with the connector 2;

[0083] The nitrogen filling channel passes through the first body 11 and the second body 12 and extends into the connector 2 .

[0084] The split design allows each part of the nitrogen charging body 1 to be independently manufactured and tested, thereby improving the stability and reliability of the overall structure. If a part fails or is damaged, it can be repaired or replaced independently without replacing the entire nitrogen charging connector, reducing maintenance costs.

[0085] It should be noted that the first body 11 and the second body 12 of the present application can both be cylindrical structures, and both bodies are provided with channels for gas to pass through to achieve nitrogen filling. A seal, such as a sealing ring, can be provided at the connection between the two bodies to improve the airtightness between the two and reduce nitrogen leakage during use.

[0086] In a more preferred implementation manner of this embodiment, a buffer spring 13 is provided between the first body 11 and the second body 12 , and one end of the buffer spring 13 abuts against the first body 11 , and the other end thereof abuts against the second body 12 .

[0087] When the nitrogen charging connector is subjected to external forces or accidental collisions, the buffer spring 13 acts as a buffer, reducing damage to the connector's internal structure. Furthermore, the buffer spring 13 can also adjust the relative position between the first body 11 and the second body 12 to a certain extent to accommodate nitrogen-charged equipment of varying lengths, increasing the connector's flexibility and applicability.

[0088] It should be noted that, in this embodiment, the second body 12 and the first body 11 can be sleeved, for example, the second body 12 is sleeved on one end of the first body 11, so that the second body 12 can slide on the first body 11 along the axis of the first body 11, so that when the second body 12 is squeezed, it can squeeze the buffer spring 13, and the buffering effect is achieved by the buffer spring 13.

[0089] When the gas nozzle 3 is connected to the equipment to be nitrogen-filled, the force between the gas nozzle 3 and the equipment to be nitrogen-filled will react on the nitrogen-filling body 1. At this time, the buffer spring 13 plays a buffering role, reducing the force of the equipment to be nitrogen-filled on the nitrogen-filling body 1 and reducing damage to the nitrogen-filling body 1.

[0090] Example 6

[0091] This embodiment is improved on the basis of embodiment 5.

[0092] like Figure 1-Figure 7 As shown, in this embodiment, a locking structure is provided on the first body 11 , and the locking structure includes a threaded segment 111 and a nut 112 provided on the first body 11 . Two nuts 112 are provided, and both nuts 112 are threadedly connected to the threaded segment 111 .

[0093] By rotating the nuts 112, their positions on the threaded section 111 can be adjusted, so the distance between the two nuts 112 can be adjusted. In actual use, the distance between the two can be changed according to actual needs so that the two nuts 112 can be fixed in different installation positions.

[0094] In practical applications, when the position of the first body 11 needs to be fixed, it can be achieved by tightening the two nuts 112 to prevent the first body 11 from moving or loosening during use.

[0095] The locking structure of the double nut 112 can more effectively fix the first body 11 to prevent displacement or loosening due to vibration or other external forces, thereby improving the stability of the entire nitrogen filling body 1.

[0096] When the first body 11 or connected components need to be maintained or replaced, they can be disassembled by simply loosening the nut 112, making maintenance work more convenient and quick.

[0097] Furthermore, the design of the threaded section 111 and the nut 112 can evenly distribute the tightening force, reduce local stress concentration, and thus improve the durability and reliability of the entire locking structure.

[0098] Example 7

[0099] like Figure 1-Figure 7 As shown, this embodiment provides a nitrogen charging device, which includes a driving device and a mounting plate 4. The mounting plate 4 is fixed to the output end of the driving device, and the nitrogen charging connector as described above is provided on the mounting plate 4.

[0100] The mounting plate 4 is fixed to the output end of the driving device and is used to support and position the nitrogen charging connector.

[0101] In this embodiment, a clamping groove 41 is provided on the mounting plate 4. Two clamping grooves 41 are provided, and the two clamping grooves 41 are provided on opposite sides of the mounting plate 4. The two clamping grooves 41 are located on the same straight line; the nitrogen filling connector is clamped on the clamping groove 41.

[0102] The locking structure is connected to the mounting groove 22, so that the position of the nitrogen charging connector can be adjusted to meet different usage requirements.

[0103] In actual applications, the clamping groove 41 is a U-shaped groove, and the nitrogen filling body 1 includes a first body 11 and a second body 12 connected to each other. The first body 11 is provided with a locking structure, which includes a threaded segment 111 and a nut 112 provided on the first body 11. Two nuts 112 are provided, and both nuts 112 are threadedly connected to the threaded segment 111.

[0104] The first body 11 is secured to the U-shaped groove via a locking mechanism. Therefore, its position within the groove can be adjusted as needed to meet different usage requirements. Adjustment is accomplished as follows: Each clamping groove 41 is provided with a nitrogen charging connector, with the axes of the two connectors parallel to each other. To change the relative distance between the two connectors, loosen the nuts 112 to increase the distance between them. The nitrogen charging mechanism can then be moved to adjust the distance between the axes of the two connectors to accommodate nitrogen charging needs for different devices.

[0105] More specifically, the driving device in this embodiment is a multi-degree-of-freedom robotic arm, comprising a base, an arm, a wrist, and an end effector. The end effector is designed to connect to the mounting plate 4 and can be a clamping mechanism or a dedicated interface.

[0106] In actual use, the robotic arm is equipped with an advanced control system that receives information about the location of the equipment to be filled with nitrogen and calculates the optimal path and motion instructions. Position sensors, vision sensors, and distance sensors are integrated into the robotic arm to monitor the status of the robotic arm and the nitrogen charging connector in real time. Based on this sensor feedback, the control system automatically adjusts the robotic arm's movements to ensure precise alignment of the nitrogen charging connector with the equipment being filled. The robotic arm's design offers a high degree of flexibility and adaptability, allowing it to accommodate equipment of varying sizes, shapes, and locations. Furthermore, collision detection and emergency stop functions ensure a rapid response in the event of an emergency to prevent damage.

[0107] When nitrogen charging is required, the position of the equipment to be charged with nitrogen is obtained, and then the robotic arm drives the mounting plate 4 to move, so that the nitrogen charging connector moves to the target position and docks with the nitrogen charging interface of the equipment to be charged with nitrogen. At this time, nitrogen charging can begin.

[0108] Example 8

[0109] This embodiment is improved on the basis of embodiment 7.

[0110] like Figure 1-Figure 7 As shown, in this embodiment, the nitrogen charging device further includes a gas supply device and a controller, and a gas valve is provided on the gas supply device, and the gas valve is communicated with the nitrogen charging channel;

[0111] The controller is provided with a timer, and the timer and the gas valve are both electrically connected to the controller.

[0112] In the traditional nitrogen filling process, manual operation is usually relied on to control the gas valve to achieve control of the nitrogen filling time. This method is not only inefficient but also prone to operational errors due to human factors.

[0113] The nitrogen filling device provided in this embodiment includes key components such as a gas supply device, a controller, a gas valve, and a timer. The gas valve is connected to the nitrogen filling channel and is used to control the supply of nitrogen. The timer is electrically connected to the controller and is used to preset and control the nitrogen filling time.

[0114] During actual use, the gas supply device serves as a nitrogen source for providing nitrogen. The gas supply device includes a nitrogen cylinder or a nitrogen generator: the core of the gas supply device is the nitrogen source, which can be one or more high-pressure nitrogen cylinders, or a nitrogen generator that produces nitrogen on-site. Nitrogen cylinders usually store compressed nitrogen, while nitrogen generators separate nitrogen from the air through a specific process (such as PSA pressure swing adsorption technology). The gas supply device also includes a pressure reducing valve and a pressure gauge. The pressure reducing valve is used to adjust the high-pressure nitrogen output from the nitrogen cylinder or generator to a pressure range suitable for subsequent use. The pressure gauge is used to monitor and display the adjusted nitrogen pressure. In a more preferred embodiment, the gas supply device also includes a gas filtration and purification system. The gas filtration and purification system also includes a filter and a dryer. The filter is used to remove impurities, particulate matter or oil in the nitrogen to ensure the purity of the nitrogen. The dryer is used to remove moisture that may be present in the nitrogen source to prevent damage to the equipment or product during subsequent use.

[0115] The gas supply device is equipped with a valve connected to the nitrogen charging channel to control the flow of nitrogen. The controller is the core component of this automated nitrogen charging device, providing data processing and control functions. The controller is equipped with a timer to preset and control the nitrogen charging time. The timer can set the nitrogen charging time and notify the controller via an electrical signal when the preset time is reached. Upon receiving the signal, the controller instructs the valve to close, thus ending the nitrogen charging process.

[0116] The timer can be an SH-1 industrial timer, which features a preset timer function, allowing the user to set a specific nitrogen filling time. When the preset time is reached, a signal is automatically triggered, notifying the controller to close the gas valve. Multiple timing modes, such as countdown and forward, may be provided to accommodate different nitrogen filling requirements. Specifically, the timer housing should be constructed of durable materials capable of withstanding a certain degree of physical impact. It should also be waterproof and dustproof to accommodate diverse environments.

[0117] The device's controller allows the user to preset the nitrogen filling time. Once the preset time is reached, the controller uses an electrical signal to close the gas valve, automatically ending the filling process. This automated control method reduces the need for manual monitoring and operation, improving the efficiency of the nitrogen filling process. Automated control ensures accurate nitrogen filling time, avoiding premature or late termination due to human error. The automated control system reduces the need for direct operator intervention during the nitrogen filling process, reducing safety risks. By precisely controlling the nitrogen filling time, nitrogen gas waste is avoided and resource utilization is optimized.
