Description

Technical Field

[0001] The utility model relates to the technical field of gas stove manufacturing, in particular to an air tightness testing device for a connection seat of a gas stove. Background Art

[0002] With the increasing popularity of household gas appliances and technological advancements, gas stoves, an indispensable part of the kitchen, are attracting increasing attention for their safety. The airtightness of the connector is a key factor in ensuring the safety of gas stoves. As the connecting component between the gas pipeline and the gas cooker, leaks in the connector can not only waste gas but also potentially cause serious safety hazards such as fires and explosions. Therefore, airtightness testing of the connector is particularly important.

While the water testing method is intuitive, it is complex, inefficient, and difficult to automate. Traditional air testing methods typically require manually sealing each connector interface and then manually observing the pressure gauge to determine air tightness. This method is not only labor-intensive, but also significantly impacts test results due to human factors, making accuracy difficult to guarantee. Utility Model Content

[0059] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent like or similar structures, and thus their detailed description will be omitted.

[0060] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0061] One of the core components of a gas stove: the connection seat, also called the burner, has the following main functions:

[0062] Gas distribution: The connector is responsible for evenly distributing gas from the main gas source to each burner. It usually has one or more inlet and outlet ports to ensure that each burner has an adequate gas supply.

[0063] Ignition system integration: The connector usually integrates an ignition device, such as an electric spark generator or thermocouple. These devices are used to ignite the gas and start the combustion process when the user operates it.

[0064] Flame Adjustment: The connection base is designed with a regulating valve or knob, allowing the user to adjust the gas flow as needed, thereby controlling the flame size and temperature. This allows for flexible selection of different fire intensities during cooking.

[0065] Safety protection: Some advanced models of the connection socket are also equipped with an automatic flameout protection device. When an abnormal situation is detected (such as excessive wind causing the flame to go out), the gas supply will be cut off immediately to prevent accidents.

[0066] Structural support: As an important component of the entire gas stove, the connector also needs to provide solid mechanical support to ensure that all components can fit closely and maintain stable operation.

The above schematic diagram only illustrates the structural relationship related to the invention and is not intended to be an actual scale of the actual product.

[0068] like Figures 1 to 6 As shown, a gas stove connection socket air tightness test device includes: a fixing mechanism 1, a nozzle sealing mechanism 2 and an air inlet inflation mechanism 3; the fixing mechanism 1 is provided with a mounting position for fixing the connection socket, and the connection socket is fixed at the mounting position; the nozzle sealing mechanism 2 is provided on the fixing mechanism 1, and seals the nozzle of the connection socket; the air inlet inflation mechanism 3 is provided on the fixing mechanism 1, connected to the air inlet of the connection socket, and rushes high-pressure air into the connection socket through the air inlet.

[0069] The testing process is as follows:

[0070] First, place the connector to be tested on the mounting position of fixture 1. A properly designed mounting position ensures the connector is securely fixed to the test fixture. If the connector is not positioned correctly, fine-tune it manually or automatically to ensure that the connector's nozzle and air inlet are aligned with the corresponding components of the test fixture.

[0071] The nozzle sealing mechanism 2 is activated to seal the nozzle holes, ensuring that all nozzle holes are effectively sealed to prevent air leakage during the inflation process.

[0072] The air inlet charging mechanism 3 is started to charge high-pressure air into the connecting seat through the air inlet.

[0073] Maintain the specified air pressure and monitor the air pressure data with an air tightness tester within a fixed time (e.g. 30 seconds). If the air pressure data remains unchanged or changes slightly within the allowable range, the air tightness of the connector is considered to meet product requirements.

[0074] After the test is completed, the air inlet inflation mechanism 3 is closed to release the high-pressure air in the connecting seat.

[0075] The nozzle sealing mechanism 2 is activated to reset it and separate it from the nozzle hole.

[0076] Start the fixing mechanism 1 to reset it and release the clamping of the connecting seat.

[0077] The tested connection base is removed from the fixing mechanism 1 and prepared for the next test.

[0078] In one embodiment, the fixing mechanism 1 includes a fixing support frame 11 and a clamping mechanism 12; the mounting position is set on the fixing support frame 11; one end of the clamping mechanism 12 is connected to the fixing support frame 11, and the other end rests on the connecting seat.

[0079] The fixed support frame 11 provides basic support for the entire test device, ensuring that the connector remains stable during the test. The specific structure is as follows:

[0080] The fixing plate 111 serves as the base for the support frame 11, upon which all other components are mounted. It is typically made of high-strength metal (such as steel or aluminum alloy) to ensure sufficient rigidity and durability. It is generally rectangular or square in shape, with a flat surface, facilitating the installation and positioning of other components. The fixing plate 111 is provided with multiple mounting holes for securing other components.

[0081] The first fixing bracket 112 is located on top of the fixing plate 111 and is used to fix a portion of the connector. If a connector is provided, this ensures that the connector does not shift during testing. Like the fixing plate 111, it is made of high-strength metal. Its shape is designed based on the specific shape and size of the connector. It is secured to the fixing plate 111 with bolts or other fasteners to ensure stability. The first fixing bracket 112 is provided with a positioning portion for aligning with a positioning point on the connector to ensure precise fixation of the connector.

[0082] The second fixing bracket 113 is located on top of the fixing plate 111 and is used to fix another part of the connecting seat. If a connecting seat is provided, it further ensures that the connecting seat will not shift during the test. Like the fixing plate 111, it is made of high-strength metal material. The shape is designed according to the specific shape and size of the connecting seat. It is fixed to the fixing plate 111 with bolts or other fasteners to ensure stability. The second fixing bracket 113 is provided with a positioning portion for aligning with the positioning point on the connecting seat to ensure the precise fixation of the connecting seat.

[0083] The clamping mechanism 12 is a key component in the connector airtightness tester, used to securely fix the connector in place and prevent displacement during testing. The clamping mechanism 12 comprises a top clamping mechanism 121 and a side clamping mechanism 122, which work together to ensure the connector's stability and reliability during testing.

[0084] The clamping mechanism 12 includes a top clamping mechanism 121 and a side clamping mechanism 122; one end of the top clamping mechanism 121 is connected to the fixed support frame 11, and the other end rests on the top of the connecting seat; one end of the side clamping mechanism 122 is connected to the fixed support frame 11, and the other end rests on the side of the connecting seat.

[0085] Specifically, the top clamping mechanism 121 includes a top bracket 1211 and a top telescopic mechanism 1212; the top bracket 1211 is installed on the fixed support frame 11, the cylinder bottom of the top telescopic mechanism 1212 is connected to the top bracket 1211, and the cylinder rod of the top telescopic mechanism 1212 is against the top of the connecting seat.

[0086] The main function of the top clamping mechanism 121 is to fix the top of the connecting seat to prevent the connecting seat from moving up and down during the test process.

[0087] The top bracket 1211 provides support for the top clamping mechanism 121, ensuring the installation and operation of the top telescopic mechanism 1212. It is typically made of high-strength metal (such as steel or aluminum alloy). Its shape is designed based on the specific shape and size of the connecting base. It is fixed to the fixing plate 111 of the fixed support frame 11 using bolts or other fasteners.

[0088] The top telescopic mechanism 1212 can be a pneumatic cylinder, which clamps the top of the connector through its telescopic action. The bottom of the cylinder is connected to the top bracket 1211 to ensure the cylinder is firmly installed. The cylinder rod is retractable and rests on the top of the connector when extended.

[0089] The end of the cylinder rod is usually made of soft materials (such as rubber or soft plastic) to avoid damage to the surface of the connection seat. According to the shape design of the top of the connection seat, ensure that the contact area is large enough and the clamping effect is good.

[0090] Working principle of the top clamping mechanism 121: When the top clamping mechanism 121 is started, the cylinder receives a control signal, and the cylinder rod extends and rests against the top of the connecting seat.

[0091] Through the telescopic action of the cylinder, the top of the connecting seat is firmly fixed on the installation position to prevent up and down displacement during the inflation process.

[0092] Specifically, the lateral clamping mechanism 122 includes a lateral bracket 1221 and a lateral telescopic mechanism 1222; the lateral bracket 1221 is installed on the fixed support frame 11, the cylinder bottom of the lateral telescopic mechanism 1222 is connected to the lateral bracket 1221, and the cylinder rod of the lateral telescopic mechanism 1222 is against the side of the connecting seat.

[0093] The main function of the lateral clamping mechanism 122 is to fix the side of the connecting seat to prevent the connecting seat from shifting left and right during the inflation process.

[0094] Lateral bracket 1221 provides support for lateral clamping mechanism 122, ensuring the installation and operation of lateral telescopic mechanism 1222. It is typically made of high-strength metal (such as steel or aluminum alloy). Its shape is designed based on the specific shape and size of the connecting base. It is secured to the fixing plate 111 of the fixed support frame 11 via bolts or other fasteners.

[0095] The lateral telescopic mechanism 1222 can be a cylinder, and the side of the connecting seat can be clamped through the telescopic action of the cylinder.

[0096] The bottom of the cylinder is connected to the lateral bracket 1221 to ensure the stable installation of the cylinder. The cylinder rod is retractable and can be abutted against the side of the connecting seat when extended.

[0097] The end of the cylinder rod is usually made of soft materials (such as rubber or soft plastic) to avoid damage to the surface of the connection seat. According to the shape design of the side of the connection seat, ensure that the contact area is large enough and the clamping effect is good.

[0098] The working principle of the lateral clamping mechanism 122 is as follows: when the lateral clamping mechanism 122 is started and the cylinder receives a control signal, the cylinder rod extends and rests against the side of the connecting seat.

[0099] The side of the connecting seat is firmly fixed to the installation position through the telescopic action of the cylinder to prevent left and right displacement during the inflation process.

[0100] In one embodiment, the nozzle sealing mechanism 2 includes multiple nozzle sealing plugs 21 and a nozzle moving structure 22; the nozzle moving structure 22 is installed on the fixing mechanism 1; multiple nozzle sealing plugs 21 are installed at the output end of the nozzle moving structure 22, and the multiple nozzle sealing plugs 21 are blocked on the nozzle of the connecting seat through the nozzle moving structure 22.

[0101] The nozzle sealing mechanism 2 is a key component in the connector airtightness test device, used to seal the connector nozzle to prevent air leakage during inflation. This mechanism includes multiple nozzle sealing plugs 21 and a nozzle moving mechanism 22. The nozzle moving mechanism 22 accurately pushes the multiple nozzle sealing plugs 21 into the nozzle holes to achieve a seal.

[0102] The nozzle moving structure 22 accurately pushes the multiple nozzle sealing plugs 21 into the nozzle holes to achieve sealing.

[0103] The nozzle sealing plug 21 seals the nozzle hole of the connector to prevent gas leakage. It is typically made of a soft material (such as rubber or soft plastic) to ensure a good seal and avoid damage to the connector surface. The design is based on the shape and size of the nozzle hole, ensuring that the sealing plug completely fills the nozzle hole, leaving no gaps.

[0104] Specifically, the nozzle moving structure 22 includes a first rack 221, a gear 222, a second rack 223 and a moving drive mechanism 224; the gear 222 is rotatably installed on the fixing mechanism 1; the first rack 221 and the second rack 223 are slidingly connected to the fixing mechanism 1, so that the first rack 221 and the second rack 223 are respectively located on both sides of the gear 222 and meshed with the gear 222; the moving drive mechanism 224 is installed on the fixing mechanism 1, and the output end is connected to the first rack 221 or the second rack 223 to drive the sliding of the first rack 221 or the second rack 223.

[0105] The gear 222 drives the linear motion of the first rack 221 and the second rack 223 through rotational motion. It is usually made of high-strength metal materials (such as steel or aluminum alloy) to ensure wear resistance and durability.

[0106] The gear 222 is rotatably mounted on the fixing mechanism 1 via a bearing to ensure smooth rotation. Both sides of the gear 222 are respectively engaged with the first rack 221 and the second rack 223 to ensure synchronous movement.

[0107] The first rack 221 is meshed with the gear 222 to achieve the movement of the nozzle sealing plug 21 through linear motion. It is usually made of high-strength metal materials (such as steel or aluminum alloy) to ensure wear resistance and durability. The first rack 221 is long and has evenly distributed teeth on the side, which meshes with the gear 222. The first rack 221 is slidably connected to the linear guide rail on the fixed mechanism 1 to ensure smooth movement. One end of the first rack 221 is connected to the output end of the mobile drive mechanism 224, and linear motion is achieved by the drive of the mobile drive mechanism 224.

[0108] The second rack 223 meshes with the gear 222, moving the nozzle seal 21 through linear motion. It is typically made of a high-strength metal material (such as steel or aluminum alloy) to ensure wear resistance and durability. The first rack 221 is elongated, with evenly spaced teeth on its sides, and meshes with the gear 222. The second rack 223 is slidably connected to a linear guide rail on the fixed mechanism 1, ensuring smooth movement. The rotation of the gear 222 drives the second rack 223 to move linearly.

[0109] The mobile drive mechanism 224 provides power to drive the linear motion of the first rack 221 or the second rack 223. The mobile drive mechanism 224 can be a pneumatic cylinder. The cylinder base is mounted on the fixing mechanism 1 to ensure stability. The cylinder rod is retractable, with its end connected to the first rack 221.

[0110] The control system receives instructions to control the extension and contraction of the cylinder, thereby driving the linear motion of the first rack 221 .

[0111] Here's how it works:

[0112] The mobile drive mechanism 224 is activated. After receiving the control signal, the mobile drive mechanism 224 (such as a cylinder) extends the cylinder rod, pushing the first rack 221 to slide along the linear guide rail on the fixed mechanism 1. The gear 222 rotates under the push of the first rack 221, driving the second rack 223 to move in the opposite direction.

[0113] The movement of the first rack 221 and the second rack 223 accurately pushes the multiple nozzle sealing plugs 21 into the nozzle holes of the connecting seat to achieve sealing.

[0114] Detailed operation steps:

[0115] In the initial state, the first rack 221 and the second rack 223 are in the initial position, the nozzle sealing plug 21 has not entered the nozzle hole, and the gear 222 is in the middle position, meshing with the first rack 221 and the second rack 223.

[0116] The mobile driving mechanism 224 is started. When the mobile driving mechanism 224 (such as a cylinder) receives a control signal, the cylinder rod extends to push the first rack 221 to slide in a certain direction along the linear guide rail on the fixing mechanism 1 .

[0117] The gear 222 starts to rotate under the push of the first rack 221 .

[0118] The rotation of the gear 222 drives the second rack 223 to move in the reverse direction.

[0119] The movement of the first rack 221 and the second rack 223 pushes the plurality of nozzle sealing plugs 21 into the nozzle holes through the sealing plug connecting frame 23 .

[0120] When the first rack 221 and the second rack 223 move to the predetermined position, the nozzle sealing plug 21 completely enters the nozzle hole to achieve sealing, and the cylinder stops moving to maintain the sealing state.

[0121] After the test is completed, the mobile drive mechanism 224 (such as a cylinder) receives a control signal, the cylinder rod retracts, and the first rack 221 and the second rack 223 return to their initial positions. The nozzle sealing plug 21 is withdrawn from the nozzle hole, and the test is completed.

[0122] The sliding connection in the above embodiment is as follows:

[0123] The bottom of the rack (the first rack 221 and the second rack 223) is provided with a protrusion or groove, and the top of the first fixing bracket 112 and the second fixing bracket 113 of the fixing mechanism 1 is provided with grooves or protrusions that match the protrusions or grooves at the bottom of the rack.

[0124] Ensure that the protrusions or grooves at the bottom of the racks (the first rack 221 and the second rack 223) are tightly matched with the grooves or protrusions of the fixing bracket to provide stable sliding support.

[0125] In one embodiment, the plurality of nozzle sealing plugs 21 include a first side nozzle sealing plug group 211 and a second side nozzle sealing plug group 212 ; the first side nozzle sealing plug group 211 is mounted on the first rack 221 ; the second side nozzle sealing plug group 212 is mounted on the second rack 223 .

[0126] In the nozzle sealing mechanism 2, multiple nozzle sealing plugs 21 are divided into a first side nozzle sealing plug group 211 and a second side nozzle sealing plug group 212, which are respectively installed on the first rack 221 and the second rack 223. The specific structure is as follows:

[0127] The first side nozzle sealing plug assembly 211 is mounted on the first rack 221. At least one nozzle sealing plug 21 in the first side nozzle sealing plug assembly 211 is used to seal the nozzle at a corresponding position on the connector. The number of nozzle sealing plugs 21 in the first side nozzle sealing plug assembly 211 depends on the structure of the connector.

[0128] The second side nozzle sealing plug assembly 212 is mounted on the second rack 223. At least one nozzle sealing plug 21 in the second side nozzle sealing plug assembly 212 is used to seal the nozzle at a corresponding position on the connector. The number of nozzle sealing plugs 21 in the second side nozzle sealing plug assembly 212 depends on the structure of the connector.

[0129] In one embodiment, the nozzle sealing mechanism 2 further includes a sealing plug connecting frame 23 ; the sealing plug connecting frame 23 is mounted on the first rack 221 ; and the first side nozzle sealing plug group 211 is mounted on the sealing plug connecting frame 23 .

[0130] The sealing plug connector 23 provides a fixed platform, ensuring that the first side nozzle sealing plug assembly 211 remains stable during movement. It is typically made of high-strength metal materials (such as steel or aluminum alloy) to ensure wear resistance and durability. The design is based on the number and arrangement of the first side nozzle sealing plug assembly 211 to ensure that each sealing plug has a fixed position. The sealing plug connector 23 is secured to the first rack 221 and the second rack 223 using bolts or other fasteners.

[0131] In one embodiment, the air inlet inflation mechanism 3 includes a sealing inflation plug 31, a motion drive mechanism 32 and an inflation mechanism; the motion drive mechanism 32 is installed on the fixing mechanism 1; the sealing inflation plug 31 is installed at the output end of the motion drive mechanism 32, and is connected to the air inlet of the connecting seat through the sealing inflation plug 31; the inflation mechanism is connected to the sealing inflation plug 31, and high-pressure air is rushed into the connecting seat.

[0132] Specifically, one end of the sealing and inflating plug 31 is connected to the output end of the motion driving mechanism 32, and the other end is provided with a groove 33 adapted to the air inlet; an inflation hole 34 connected to the bottom of the groove 33 is provided on the side wall of the sealing and inflating plug 31; the inflation mechanism is connected to the inflation hole 34.

[0133] In this embodiment, the air inlet inflation mechanism 3 includes a sealing inflation plug 31, a motion drive mechanism 32, and an inflation mechanism. These components work together to ensure that the air inlet of the connector is effectively sealed and that high-pressure air is injected into the connector through the air inlet inflation mechanism 3. The following is a detailed description of the structure:

[0134] The sealing inflation plug 31 is connected to the air inlet of the connecting seat to ensure sealing during the inflation process. Material: Soft materials (such as rubber or soft plastic) are usually used to ensure the sealing effect and avoid damage to the surface of the connecting seat. One end of the sealing inflation plug 31 is designed with a groove 33 that adapts to the air inlet of the connecting seat to ensure that the air inlet of the connecting seat is completely sealed during the inflation process. An inflation hole 34 connected to the bottom of the groove 32 is provided on the side wall of the sealing inflation plug 31 for connecting the air pipe of the inflation mechanism.

[0135] The sealing and inflating plug 31 is installed at the output end of the motion driving mechanism 32 , and is driven by the motion driving mechanism 32 to push the sealing and inflating plug 31 into the air inlet of the connecting seat.

[0136] The motion driving mechanism 32 provides power to drive the sealing and inflating plug 31 to connect with the air inlet of the connecting seat.

[0137] The motion driving mechanism 32 can be a cylinder, and the bottom of the cylinder is installed on the fixing mechanism 1 to ensure stability.

[0138] The cylinder rod is retractable, and the end is connected to the sealing inflation plug 31. The cylinder can be fixed to the fixing plate of the fixing mechanism by bolts or other fasteners to ensure the stable installation of the cylinder.

[0139] The inflation mechanism (not shown in the figure) fills the connecting seat with high-pressure air to perform an airtightness test.

[0140] An air pump can be selected and connected to the air hole 34 in the air-sealed air plug 31 through an air pipe to ensure that high-pressure air can enter the connecting seat smoothly.

[0141] The air tightness tester is used to monitor the air pressure changes during the inflation process and determine the air tightness of the connector.

[0142] The sealing and inflating plug 31 is constructed of a soft material, ensuring a tight fit with the connector's air inlet, preventing air leakage and improving test reliability. The motion drive mechanism 32 quickly and accurately pushes the sealing and inflating plug 31 into the connector's air inlet, significantly reducing inflation and sealing time and improving test efficiency. The control system automatically controls the cylinder's retraction and expansion, simplifying operation. Precise positioning of the sealing and inflating plug is achieved solely through control system instructions, minimizing manual intervention and simplifying operational difficulty.
