Description

Technical Field

[0001] The invention relates to the technical field of gas hose connection, and in particular to a household gas hose connection device. Background Art

[0002] With the acceleration of urbanization, residents' demand for clean energy such as natural gas is growing. In home kitchens, gas stoves are the main cooking tools, and their safety and convenience have become the focus of people's attention. As a key component connecting the gas source and the stove, the performance of the gas hose directly affects the safety and reliability of gas use. However, the traditional gas hose connection method has many shortcomings, such as poor interface sealing, inconvenient installation, and short service life. These problems not only affect the user experience, but also may bring safety hazards.

[0003] When using existing gas hoses, they usually need to be used in conjunction with connectors, but the length of the gas hose will be adjusted according to the actual usage scenario. After the gas hose is adjusted to an appropriate length, it needs to be connected to the connector, but the process of connecting with the connector is usually cumbersome. The operator needs to force the connector into the hose, and the success rate of the operation is low, which affects the operator's work progress.

[0004] In order to solve the above problems, new types of gas hose connection devices continue to appear on the market. These devices are usually designed to improve the safety, stability and durability of the connection, while simplifying the installation process and reducing the risks caused by improper operation. For example, some designs use tighter thread fit or add leak-proof devices to enhance the sealing effect; some improve the hose's anti-aging ability and extend its service life by optimizing material selection; and some designs introduce quick connector technology, allowing users to easily complete installation and removal without professional tools.

[0005] Despite this, existing solutions still have certain limitations, especially when facing gas equipment of different brands and models, the compatibility issue is particularly prominent. In addition, how to further reduce manufacturing costs while ensuring efficient connection is also one of the important factors that current R&D personnel need to consider.

[0045] Specifically, in the initial state, the airbag 223 is located in the mounting groove 222; when in use, the connector 5 is sleeved on the support plate 41, the gas hose 6 is placed on a side close to the inner clamping piece 22, and then the sliding rod 21 is moved in the direction close to the gas hose 6, the sliding rod 21 drives the inner clamping piece 22 to move, and the inner clamping piece 22 enters the gas hose 6 during the movement, and then the airbag 223 is inflated to expand the airbag 223, and the outer wall of the airbag 223 contacts the inner wall of the gas hose 6, and then the outer clamping mechanism 3 is moved to the same plane as the inner clamping piece 22, and then the outer clamping mechanism 3 contacts the gas hose 6. The outside of the gas hose 6 is clamped, and the gas hose 6 is clamped under the action of the airbag 223 and the outer clamping mechanism 3, and then the sliding rod 21 and the outer clamping mechanism 3 are moved at the same time, so that the inner clamping member 22 moves toward the direction close to the support plate 41, and the inner clamping member 22 and the outer clamping mechanism 3 drive the gas hose 6 to move, and the gas hose 6 is sleeved on the connector 5. When the gas hose 6 moves a certain distance on the connector 5, the airbag 223 is deflated, and the outer clamping mechanism 3 releases the gas hose 6 at the same time; then repeat the above steps, clamp the gas hose 6 again and move it on the connector 5, and repeat the above steps multiple times to sleeve the gas hose 6 on the connector 5.

[0046] By setting the inner clamping piece 22, the inner wall of the gas hose 6 can be clamped, and by setting the outer clamping mechanism 3, the outer side of the gas hose 6 can be clamped. The inner clamping piece 22 cooperates with the outer clamping mechanism 3 to clamp the gas hose 6 together, thereby improving the clamping stability. The gas hose 6 can be moved under the clamping of the inner clamping piece 22 and the outer clamping mechanism 3, so that the gas hose 6 is sleeved on the connector 5, which saves the operator's operation, facilitates the docking of the connector 5 and the gas hose 6, and improves the operator's work efficiency.

[0047] like Figure 2 , 4 As shown in , 6 and 7, the inner clamping mechanism 2 also includes a moving part 23, and the moving part 23 includes a cylinder 231 fixedly connected in the shell 1, a moving plate 232 is slidably arranged in the cylinder 231, the sliding rod 21 extends into the cylinder 231, the sliding rod 21 is fixedly connected to the moving plate 232, a first spring 233 is connected between the moving plate 232 and the cylinder 231, an air pump 7 is arranged in the shell 1, the output end of the air pump 7 is connected to the cylinder 231, the air pump 7 is located on the side of the moving plate 232 away from the sliding rod 21, an electromagnetic exhaust valve 234 is arranged on the cylinder 231, and the electromagnetic exhaust valve 234 is connected to the internal space of the cylinder 231.

[0048] Specifically, during use, when the sliding rod 21 needs to move, the air pump 7 is started, and the air pump 7 inflates the cylinder 231 so that the gas pushes the moving plate 232 to move. During the movement of the moving plate 232, the moving plate 232 drives the sliding rod 21 to move, and the moving plate 232 compresses the first spring 233; when the sliding rod 21 needs to be reset, the air pump 7 is turned off, and the electromagnetic exhaust valve 234 is opened at the same time. The moving plate 232 is reset under the action of the first spring 233, and the gas in the cylinder 231 is discharged through the electromagnetic exhaust valve 234.

[0049] By setting the movable part 23, the movable plate 232 can be pushed to move by supplying air through the air pump 7, and the movement of the movable plate 232 drives the movement of the sliding rod 21, so that the inner clamping part 22 can move, making it convenient for the gas hose 6 to be installed on the connector 5.

[0050] Furthermore, the electromagnetic exhaust valve 234 is a prior art and will not be described in detail.

[0051] like Figure 4 , 5 As shown in Figures 7, 8, 9 and 10, an air guide member 24 is provided in the sliding rod 21 and the fixed plate 221, and the air guide member 24 includes an air groove 241 opened in the sliding rod 21, the air groove 241 penetrates the movable plate 232, the air groove 241 is connected with the internal space of the cylinder 231, an air cavity 242 is opened in the fixed plate 221, the air groove 241 is connected with the air cavity 242, four connecting grooves 243 are evenly opened on the circumferential inner wall of the air cavity 242 along the circumferential direction, the connecting groove 243 is connected with the internal space of the airbag 223, and an electromagnetic air intake valve 244 is provided in the air groove 241.

[0052] Specifically, during use, when the airbag 223 needs to be inflated, the electromagnetic air inlet valve 244 is started, so that the gas in the cylinder 231 enters the air cavity 242 through the air groove 241, and then the gas enters the airbag 223 through the connecting groove 243, so that the airbag 223 is inflated. After the airbag 223 is inflated, the electromagnetic air inlet valve 244 is closed to keep the airbag 223 in an inflated state; when the airbag 223 needs to be deflated, the electromagnetic air inlet valve 244 is opened, and the airbag 223 discharges the gas in the airbag 223 into the air groove 241 through the air cavity 242 under the action of its own elastic force.

[0053] By setting the gas guide 24, when the moving member 23 is moved by the gas, the gas can be guided into the airbag 223, so that the airbag 223 expands and clamps the inner wall of the gas hose 6, thereby facilitating the connection between the gas hose 6 and the connector 5.

[0054] Furthermore, the electromagnetic intake valve 244 is a prior art and will not be described in detail.

[0055] like Figure 2 , 4 As shown in Figures 6 and 7, an auxiliary part 25 is provided in the shell 1, and the auxiliary part 25 includes a closing plate 251 fixedly sleeved on the cylinder 231, and the closing plate 251, the inner wall of the shell 1 and the cylinder 231 form a closed space, and the electromagnetic exhaust valve 234 is communicated with the closed space, a sliding ring 252 is slidably sleeved on the cylinder 231, and a supporting ring 253 is fixedly sleeved on the cylinder 231, and a second spring 254 is connected between the sliding ring 252 and the supporting ring 253, and four connecting rods 255 are evenly fixedly connected to the sliding ring 252 along the circumferential direction, and the connecting rods 255 extend out of the shell 1 in the direction close to the joint 5, and the extending ends of the four connecting rods 255 are commonly fixedly connected to a push ring 256, and a rubber ring is fixedly connected to the side of the push ring 256 away from the shell 1, and an electromagnetic exhaust valve 257 is provided on the closing plate 251, and six exhaust grooves 258 are evenly opened on the inner wall of the shell 1 along the circumferential direction.

[0056] Specifically, during use, when the sliding rod 21 drives the inner clamping piece 22 to move toward the direction close to the shell 1, that is, when the gas hose 6 moves toward the direction close to the joint 5, the gas in the cylinder 231 enters the closed space through the electromagnetic exhaust valve 234, so that the gas in the closed space increases, thereby causing the sliding ring 252 to move toward the direction close to the joint 5. At the same time, the sliding ring 252 compresses the second spring 254. When the sliding ring 252 moves, it drives the connecting rod 255 to move, and the connecting rod 255 drives the push ring 256 to move. The push ring 256 pushes the joint 5 to move toward the direction close to the gas hose 6. When the inner clamping piece 22 moves in the direction away from the shell 1, the electromagnetic exhaust valve 257 is opened, so that the gas in the closed space is discharged through the electromagnetic exhaust valve 257, and then the gas is discharged from the shell 1 through the exhaust groove 258. The sliding ring 252 is reset under the action of the second spring 254.

[0057] By setting the auxiliary part 25, when the inner clamping part 22 drives the gas hose 6 to move, the gas discharged from the cylinder 231 can be used to push the sliding ring 252 to move, so that the sliding ring 252 drives the push ring 256 through the connecting rod 255 to apply a force to the connector 5 to approach the gas hose 6, thereby assisting the docking of the gas hose 6 and the connector 5, making the docking of the gas hose 6 and the connector 5 faster.

[0058] Furthermore, the electromagnetic air outlet valve 257 is a prior art and will not be described in detail.

[0059] like Figure 5As shown, an electromagnetic ventilation valve 245 is provided on the sliding rod 21 , and the electromagnetic ventilation valve 245 is communicated with the air groove 241 . The electromagnetic ventilation valve 245 is located on a side of the electromagnetic air inlet valve 244 close to the housing 1 .

[0060] Specifically, during use, after the gas hose 6 is docked, the airbag 223 is kept inflated, and the outer clamping mechanism 3 is moved so that the joint 5 fits tightly with the rubber ring. At this time, the airbag 223, the gas hose 6, the joint 5 and the rubber ring form a relatively closed space; then the electromagnetic ventilation valve 245 is opened, and the air pump 7 is started, so that the gas in the air groove 241 is discharged through the electromagnetic ventilation valve 245. At this time, the operator detects whether there is a large amount of gas discharged from the docking point of the gas hose 6 and the joint 5, so as to detect the tightness of the connection between the gas hose 6 and the joint 5.

[0061] By setting the electromagnetic vent valve 245 , after the gas hose 6 and the connector 5 are connected, the gas in the gas groove 241 can be discharged through the electromagnetic vent valve 245 , so that the user can easily detect the connection tightness of the gas hose 6 and the connector 5 .

[0062] Furthermore, the electromagnetic ventilation valve 245 is a prior art and will not be described in detail.

[0064] Specifically, when the gas hose 6 needs to be clamped during use, the two clamping rods 31 are moved so that the two clamping rods 31 are close to each other. When the ends of the two clamping rods 31 abut against each other, the two clamping rods 31 clamp the gas hose 6.

[0065] The two clamping rods 31 are provided to clamp the gas hose 6 , and the auxiliary inner clamping member 22 clamps and moves the gas hose 6 .

[0066] like Figure 2 , 9 As shown, the external clamping mechanism 3 also includes a moving part 32, and the moving part 32 includes two electromagnetic slide rails 321 symmetrically fixedly connected to the outside of the shell 1, and each of the electromagnetic slide rails 321 is slidably connected with an electromagnetic slider 322, and each of the electromagnetic sliders 322 is fixedly connected with a fixing rod 323, and the end of the fixing rod 323 is fixedly connected with an extension rod 324, and the end of the extension rod 324 is connected to the clamping rod 31.

[0068] By disposing the moving part 32 , the clamping rod 31 can be driven to move, so that the clamping rod 31 drives the gas hose 6 to move.
