Like reference numerals in the figures denote like or similar structures, and thus their detailed description will be omitted.

[0048] The terms "a", "an", "the", etc. are used to indicate the presence of one or more elements / components / etc.; the terms "comprising" and "having" are used to mean an open inclusion and mean that there may be additional elements / components / etc. in addition to the listed elements / components / etc.

[0049] Referring to Figures 1 to 5 , an embodiment of the present utility model provides a gas stove detection device, including a platform assembly 1, a connecting seat 2, a first driving mechanism 3, and a joint assembly 4. The platform assembly 1 can provide support for the gas stove detection device of the embodiment of the present utility model, and other components can be directly or indirectly provided on the platform assembly 1.

[0050] The connecting seat 2 is provided on the platform assembly 1, and the connecting seat 2 is used to connect the gas path of the gas stove to be measured. The first driving mechanism 3 is connected to the platform assembly 1. The joint assembly 4 is connected to the first driving mechanism 3, and the joint assembly 4 can move in the vertical direction under the drive of the first driving mechanism 3 so that the joint assembly 4 can be connected to or separated from the connecting seat 2. When the first driving mechanism 3 drives the joint assembly 4 to move downward in the vertical direction, the joint assembly 4 can be connected to the connecting seat 2. When the first driving mechanism 3 drives the joint assembly 4 to move upward, the joint assembly 4 can be separated from the connecting seat 2. The joint assembly 4 is used to connect an airtightness detector so that the airtightness detector can communicate with the gas path of the gas stove to be measured through the joint assembly 4 and the connecting seat 2. When the joint assembly 4 is connected to the connecting seat 2, the airtightness detector can communicate with the gas path of the gas stove to be measured through the joint assembly 4 and the connecting seat 2, thereby enabling the detection of the airtightness of the gas path of the gas stove to be measured, reducing manual operation, reducing labor costs, and improving the accuracy of detection.

[0051] In some embodiments, referring to Figure 9 , the joint assembly 4 may have a first communication port 421 and a gas distribution interface 422 that communicate with each other. The gas distribution interface 422 is used to connect an airtightness detector. The connecting seat 2 has a second communication port 23 and a ventilation port 24 that communicate with each other. The ventilation port 24 is used to connect the gas path of the gas stove to be measured. When the joint assembly 4 is connected to the connecting seat 2, the first communication port 421 is connected to the second communication port 23, thereby enabling the airtightness detector to communicate with the gas path of the gas stove to be measured through the joint assembly 4 and the connecting seat 2.

[0052] The joint assembly 4 and the connecting seat 2 can be inserted into each other, abutted against each other, or connected in other ways that can make the joint assembly 4 and the connecting seat 2 communicate in a sealed manner.

[0053] In some embodiments, referring to Figure 3 and Figure 4 , the joint assembly 4 may include an annular frame 41, a first connector 42, and an elastic limiting component 43. The annular frame 41 may have a connection cavity and a connection port communicating with the connection cavity. One end of the annular frame 41 opposite to the connection port is connected to the first driving mechanism 3.

[0054] Referring to Figure 7 , the first connector 42 includes opposite first end 425 and second end 426. The first end 425 is movably disposed in the connection cavity. The first connector 42 has a first communication port 421 and a gas distribution interface 422 that communicate with each other. The first communication port 421 is used to connect to the connecting seat 2, and the gas distribution interface 422 is used to connect to an airtightness detector. In a specific implementation, the first connector 42 has a first communication cavity 423. The second end 426 has a first communication port 421 communicating with the first communication cavity 423. The side of the first connector 42 has a gas distribution interface 422 communicating with the first communication cavity 423. The first connector 42 communicates with the connecting seat 2 through the first communication port 421. The first communication port 421 of the first connector 42 can be sleeved on the connecting seat 2 to realize the communication between the joint assembly 4 and the connecting seat 2. The second end 426 of the first connector 42 can extend out of the connection cavity from the connection port. Of course, the second end 426 can also be flush with the connection port, or the first connector 42 is entirely located in the connection cavity, and the second end 426 faces the side of the connection port, so that when the joint assembly 4 moves vertically towards the connecting seat 2, the first communication port 421 can be connected to the connecting seat 2.

[0055] Referring to Figure 7 , the first connector 42 may include two sections with different outer diameters. For example, the outer diameter on one side of the first end 425 is smaller than the outer diameter on one side of the second end 426.

[0056] The elastic limit component 43 connects the first end 425 of the first connector 42 and the annular frame 41. The first connector 42 is axially fixed relative to the annular frame 41 through the elastic limit component 43, while being able to move relatively in the radial direction. The elastic limit component 43 can axially fix the first connector 42 and the annular frame 41 relative to each other, so that when the first driving mechanism 3 drives the connector assembly 4 to move in the vertical direction, the first connector 42 can be connected to or separated from the connection seat 2. The elastic limit component 43 can elastically limit the first connector 42 relative to the annular frame 41 in the radial direction, so that the first connector 42 can have a certain range of movement relative to the annular frame 41 in the radial direction. When there is a certain deviation between the first connector 42 and the connection seat 2 in the horizontal direction, the first connector 42 can move relative to the annular frame 41 in the radial direction under the guidance of the connection seat 2, so that the first connector 42 and the connection seat 2 are aligned, realizing automatic alignment.

[0057] In some embodiments, referring to Figure 4 and Figure 6 , the annular frame 41 may include a cylindrical body 411. A connection cavity of the annular frame 41 is formed inside the cylindrical body 411. At least one end of the cylindrical body 411 facing away from the first driving mechanism 3 is open, forming a connection port communicating with the connection cavity.

[0058] In some embodiments, referring to Figure 4 and Figure 6 , the annular frame 41 may further include a plate body 412. The plate body 412 has opposite first and second surfaces. The first surface is connected to the first driving mechanism 3, and one end of the cylindrical body 411 facing away from the connection port is connected to the second surface. The plate body 412 and the first driving mechanism 3 may be connected by screws. At least a part of the outer edge of the plate body 412 may protrude from the outer edge of the cylindrical body 411, and the part of the plate body 412 protruding from the cylindrical body 411 is connected to the first driving mechanism 3 by screws. The shape and size of the plate body 412 may also be adapted to the end of the cylindrical body 411. The screws may connect the plate body 412 and the first driving mechanism 3 through the inside of the cylindrical body 411.

[0059] The first driving mechanism 3 may be an electric cylinder, a pneumatic cylinder or a hydraulic cylinder. The first driving mechanism 3 may include a cylinder body 31 and a telescopic part 32. The telescopic part 32 may be a piston rod or a lead screw, for example. A fixing plate 33 may be provided at the end of the telescopic part 32, and the connector assembly 4 is connected to the fixing plate 33. In a specific implementation, the plate body 412 and the fixing plate 33 may be connected by screws.

[0060] In some embodiments, referring to Figures 3 to 6, there are at least three through holes 413 on the side wall of the connection cavity. The through holes 413 on the side wall of the connection cavity are used to assemble the elastic limit component 43. When the annular frame 41 includes a cylinder body 411, the cylinder body 411 constitutes the side wall of the connection cavity, and the through holes 413 are opened on the cylinder body 411. The at least three through holes 413 may be evenly distributed in the circumferential direction.

[0061] See Figures 3 to 5 , there may also be a notch on the side wall of the connection cavity. The notch axially extends from one end of the connection port. There are multiple notches arranged in the circumferential direction, and two adjacent communication holes 413 are separated by the notch.

[0062] In some embodiments, see Figures 3 to 6 , the elastic limit component 43 includes at least three connecting pieces 431 and an elastic member 432. Each connecting piece 431 slidably passes through a through hole 413, and one end of the connecting piece 431 is connected to one end of the first connecting head 42. The connecting piece 431 passes through the through hole 413 and is connected to the first connecting head 42 at one end, which can axially fix the first connecting head 42 relative to the annular frame 41. The connecting piece 431 is slidably arranged in the through hole 413, which can enable the first connecting head 42 to move radially relative to the annular frame 41, so as to be able to automatically align with the connection seat 2.

[0063] The elastic member 432 applies a force to the first connecting head 42 and the annular frame 41, so that the first connecting head 42 remains in the first position relative to the annular frame 41. Overcoming the force, the first connecting head 42 moves radially relative to the annular frame 41. When there is no external force, the elastic member 432 makes the first connecting head 42 remain in the first position relative to the annular frame 41. In a specific implementation, the first position may be the center of the connection cavity. The elastic member 432 can make the first connecting head 42 basically remain at the center of the connection cavity relative to the annular frame 41. When the first connecting head 42 is subjected to a radial external force, it will overcome the force applied by the elastic member 432 and move radially relative to the annular frame 41. For example, when there is a deviation between the connection seat 2 and the first connecting head 42 in the horizontal direction, during the process of the first driving mechanism 3 driving the joint assembly 4 to move downward, the first connecting head 42 contacts the connection seat 2, and the connection seat 2 will apply a radial component force to the first connecting head 42, so that the first connecting head 42 undergoes a radial displacement relative to the annular frame 41, realizing the automatic alignment of the first connecting head 42 and the connection seat 2.

[0064] The connecting piece 431 and the first connecting head 42 may be fixedly connected or abutted. When the connecting piece 431 abuts against the first connecting head 42, there is a groove on the first connecting head 42 for accommodating the connecting piece 431, so that the connecting piece 431 axially limits the first connecting head 42.

[0065] In some embodiments, see Figure 3 and Figure 4, the connecting member 431 is a connecting rod. One end of the connecting rod is threadedly connected to the first connecting head 42. For example, the first connecting head 42 may have threaded holes 424 evenly distributed in the circumferential direction, and one end of the connecting rod has external threads adapted to the threaded holes 424. The through hole 413 is an oblong hole, and the length direction of the through hole 413 extends along the circumferential direction. The elastic member 432 is a helical spring, and a helical spring is sleeved on each connecting rod. The two ends of the helical spring respectively abut against the first connecting head 42 and the annular frame 41. The threaded connection between the connecting rod and the first connecting head 42 facilitates the assembly of the first connecting head 42 to the annular frame 41. The use of an oblong hole for the through hole 413 allows the connecting rod to move circumferentially along the oblong hole, enabling the first connecting head 42 to move flexibly in the radial direction relative to the annular frame 41, which is beneficial for aligning the first connecting head 42 with the connecting seat 2. The two ends of the helical spring respectively abut against the first connecting head 42 and the annular frame 41, keeping the first connecting head 42 relative to the annular frame 41 in the first position. When the first connecting head 42 is subjected to an external radial force, it can overcome the force of the spring and move the first connecting head 42 relative to the annular frame 41 in the radial direction.

[0066] In some embodiments, the first connecting head 42 has an axial limiting structure. Refer to Figure 5 , the connecting member 431 is a slider. One end of the slider abuts against the first connecting head 42 and interacts with the axial limiting structure to axially limit the first connecting head 42 relative to the annular frame 41. In an exemplary embodiment, the axial limiting structure can be a groove, and the first connecting head 42 abuts within the groove. Or the axial limiting structure can be a limiting boss, and the first connecting head 42 abuts below the limiting boss. The first end 425 of the first connecting head 42 may abut against the bottom of the connecting cavity. When the annular frame 41 includes a plate body 412, the first connecting head 42 abuts against the second surface of the plate body 412. The elastic member 432 is annular, and the annular elastic member 432 is sleeved outside the annular frame 41. The other end of the slider abuts against the elastic member 432. The connecting member 431 is a slider, and the slider is in sliding fit with the through hole 413, enabling the slider to slide radially within the through hole 413. The annular elastic member 432 is sleeved outside the annular frame 41 and acts on one end of the slider, making the circumferentially arranged sliders evenly stressed. In the absence of external forces, the first connecting head 42 is basically located in the central position within the connecting cavity. When the annular frame 41 includes a cylindrical body 411, the annular elastic member 432 is sleeved outside the cylindrical body 411. The annular elastic member 432 can be, for example, a helical spring with its ends connected.

[0067] In some embodiments, refer to Figure 5, the outer surface of the annular frame 41 has a first groove in the circumferential direction. The first groove communicates with the through hole 413 in the circumferential direction. The other end of the slider has a second groove, and the second groove is opposite to the first groove in the circumferential direction. The elastic member 432 is embedded in the first groove and the second groove. Embedding the elastic member 432 in the first groove and the second groove can firmly sleeve the annular elastic member 432 on the outside of the annular frame 41 and continuously and stably apply force to the slider, and the slider transmits the force of the elastic member 432 to the first connector 42.

[0068] In some embodiments, referring to Figure 9 , the inner surface of the first communication port 421 is a conical surface, and the cross-sectional area of the first communication port 421 gradually decreases from the second end 426 to the first end 425. Referring to Figures 12a to 12c , the inner surface of the first communication port 421 is a conical surface. During the process of the first connector 42 moving downward and contacting the connection seat 2, the inner surface can play a guiding role, and the first connector 42 moves radially to align with the connection seat 2.

[0069] In some embodiments, referring to Figure 11 , the connection seat 2 has a first communication port 421 and a ventilation port 24 that communicate with each other. When the joint assembly 4 is connected to the connection seat 2, the first communication port 421 communicates with the second connection port.

[0070] The connection seat 2 may have a second communication cavity 25, and the first communication port 421 and the ventilation port 24 communicate with the second communication cavity 25 respectively.

[0071] In some embodiments, referring to Figure 11 , the connection seat 2 includes a base 21 and a second connector 22. The second communication port 23 may be provided on the second connector 22. When the joint assembly 4 is connected to the connection seat 2, the first connector 42 is connected to the second connector 22. In a specific implementation, the first communication port 421 may be sleeved outside the second connector 22, and the second connector 22 is inserted into the first connector 42. Of course, as another embodiment, the first connector 42 may also be inserted into the second connector 22.

[0072] In an exemplary embodiment, referring to Figure 11 , the base 21 has a second communication cavity 25, and the side surface of the base 21 has a ventilation port 24 for communicating with the gas path of the gas stove to be measured; the second connector 22 is provided on the top surface of the base 21, and a shoulder is formed around the second connector 22 on the top surface of the base 21. The second connector 22 has a second communication port 23 communicating with the second communication cavity 25.

[0073] Referring to Figure 11 and Figures 12a to 12c, the sealing ring 26 is sleeved outside the second connector 22 and is used for sealing between the first connector 42 and the second connector 22 when the first communication port 421 is sleeved outside the second connector 22. When the connector assembly 4 is connected to the connection base 2, the first communication port 421 of the first connector 42 is sleeved outside the second connector 22 to realize the connection between the connector assembly 4 and the connection base 2. The sealing ring 26 can seal between the first connector 42 and the second connector 22 to avoid air leakage during the test.

[0074] The second connector 22 and the base 21 can be an integral structure or, as Figure 11 shown, the second connector 22 and the base 21 are a split structure. When the second connector 22 and the base 21 are a split structure, the second connector 22 is inserted into the base 21.

[0075] See Figure 11 , the second connector 22 and the base 21 can be threadedly connected. The sealing ring 26 can be provided between the second connector 22 and the base 21. In an exemplary embodiment, the sealing ring 26 is sleeved on the second connector 22. When the second connector 22 and the base 21 are threadedly connected, the sealing ring 26 is fixed between the second connector 22 and the base 21.

[0076] In some embodiments, see Figure 2 and Figure 11 , the outer surface of the second connector 22 is a conical surface, and the cross-section of the second connector 22 gradually decreases in the direction away from the base 21. When the first connector 42 moves downward and contacts the second connector 22, the surface of the first communication port 421 contacts the outer surface of the second connector 22, and the conical surface plays a guiding role to align the first connector 42 and the second connector 22.

[0077] In some embodiments, see Figure 1 , the platform assembly 1 includes a conveyor line and a tooling plate 6, and the first driving mechanism 3 is connected to the conveyor line through a bracket 5;

[0078] The tooling plate 6 is arranged on the conveyor line and can move along the conveyor line. The connection base 2 is connected to the tooling plate 6, and the tooling plate 6 is used to support the gas stove to be tested. The gas stove to be tested is arranged on the tooling plate 6 and moves along the conveyor line with the tooling plate 6, which can form an assembly line for detection and assembly.

[0079] For the specific structure of the conveyor line and the transfer of the tooling plate 6, an assembly line with an appropriate structure can be adopted. In specific implementation, the conveyor line may include a second driving mechanism, and the second driving mechanism conveys the tooling plate 6 through one or more of a conveyor belt, a chain, a roller, a gear, etc. The conveyor line may include a positioning mechanism. When the positioning mechanism is used to convey the tooling plate 6 to a position where the connecting seat 2 and the joint assembly 4 are opposite, the conveying stops, so that the first driving mechanism 3 drives the joint assembly 4 to move downward to be connected to the connecting seat 2 for airtightness detection. Both the first driving mechanism 3 and the second driving mechanism can be controlled by a control center. For example, the control center can determine that the tooling plate 6 reaches the target position according to the signal of the positioning mechanism, thereby controlling the second driving mechanism to stop conveying and controlling the first driving mechanism 3 to drive the joint assembly 4 to move downward. After the detection is completed, the control center can control the first driving mechanism 3 to drive the joint assembly 4 to move upward to separate the joint assembly 4 from the connecting seat 2, and control the second driving mechanism to continue conveying the tooling plate 6. In specific implementation, the positioning structure may include one or more of an image acquisition device, a sensor, and a proximity switch.
