Description

Technical Field

[0001] This application relates to the field of mechanical equipment technology, specifically to a safe gas stove. Background Technology

[0002] Gas stoves are essential kitchen appliances in modern kitchens, typically consisting of a cooktop, burner, switch, cooktop support, etc. The cooktop support is a crucial component for ensuring cooking safety and efficiency, supporting pots and pans so that their bottoms are higher than the top of the burner. Existing gas stove cooktop supports have fixed shapes and dimensions. Some supports have a larger inner diameter to accommodate large round-bottomed woks (if the inner diameter is too small, the wok will tip over), while others have a smaller diameter to accommodate small saucepans (if the inner diameter is larger than the saucepan's diameter, it cannot provide effective support). Therefore, there is a need to design a cooktop support that can accommodate pots of various sizes, as well as a safer gas stove. Summary of the Invention

[0003] A safe gas stove includes a stovetop, a burner, and a stovetop support;

[0004] The stove support includes:

[0005] A rectangular frame, wherein a bottom groove is provided in the middle of the lower end face of each side of the rectangular frame;

[0006] The support assembly is provided in four units, with one support assembly respectively installed on the bottom groove of the frame. The support assembly includes a support housing, a swing rocker arm, an attitude retainer, and a synchronous resistor adjuster.

[0007] The supporting shell includes a shell base, with a snap-fit ​​bottom plate on the outer side of the shell base that snaps into the groove below the bottom of the frame. The snap-fit ​​bottom plate has a snap-fit ​​side plate at its stop end that snaps into the inner wall of the rectangular frame. The supporting shell also includes a narrow-diameter cylindrical cavity within the shell base. The narrow-diameter cylindrical cavity has an upper opening at its center. An anti-rotation insert is provided at the front and rear of the inner wall of the narrow-diameter cylindrical cavity. Wide-diameter cylindrical cavities are formed at the front and rear of the narrow-diameter cylindrical cavity. Each wide-diameter cylindrical cavity has an end opening at its end. A guide shaft groove is provided along the axial direction on the inner wall of the wide-diameter cylindrical cavity. Furthermore, at least three guide shaft grooves are provided, and the guide shaft grooves are evenly distributed along the inner circumference of the wide-diameter cylindrical cavity.

[0008] The swing rocker arm is rotatably disposed within the supporting housing; the swing rocker arm includes a rotatable rotating ring disposed within a narrow-diameter cylindrical cavity, a rocker arm plug disposed on the inner wall of the rotating ring, an upper connecting plate disposed above the rotating ring and passing through an upper opening, and a supporting horizontal plate disposed above the upper connecting plate for supporting the cookware.

[0009] The attitude retainer is located inside the support housing, enabling the rocker arm to maintain a neutral or deflected attitude. The attitude retainer includes a central sliding tube located within the rotating ring. Each wide-diameter cylindrical cavity has a limiting retaining ring on the side near the central sliding tube and a return spring on the side away from the central sliding tube. The central sliding tube includes a hollow tube body and a spiral groove on the hollow tube body that mates with the rocker arm plug. The spiral groove has a locking end groove at its front and rear ends. The lower end of the hollow tube body has an anti-rotation shaft groove for accommodating an anti-rotation insert. The locking end groove located in front of the spiral groove is positioned rearward, and the locking end groove located behind the spiral groove is positioned forward. The rocker arm plug is cylindrical, and the radius of the rocker arm plug is greater than the depth of the locking end groove.

[0010] The synchronous resistor includes:

[0011] The adjusting shaft assembly includes an external threaded rod, which passes through an end opening, a limiting retaining ring, and a centrally located slide tube. A torsion handle is provided in front of the external threaded rod, and a limiting turntable is provided behind the external threaded rod.

[0012] Two sliding adjustment plates are provided. Each wide-diameter cylindrical cavity has one sliding adjustment plate on the side away from the central sliding tube. The sliding adjustment plate includes an internally threaded ring that is slidably disposed in the wide-diameter cylindrical cavity and meshes with the externally threaded rod, and a guide block disposed on the outer wall of the internally threaded ring and inserted into the guide shaft groove.

[0013] Beneficial effects:

[0014] The safety gas stove described in this case has a support assembly for the stove stand that can be tilted inward or outward to accommodate different cookware: when tilted inward, the plane area enclosed by the support assembly is small, which is suitable for cookware for infants and young children; when tilted outward, the plane area enclosed by the support assembly is large, which is suitable for larger cookware.

[0015] The safety gas stove described in this case has a support assembly for the stove stand that can temporarily maintain a vertical posture, and can effectively maintain the deflected posture after being manually turned. It can switch between inward and outward deflection states by turning it again.

[0016] The safety gas stove described in this case can also adjust the rotational damping of the rocker arm to suit the habits of different users. Attached Figure Description

[0041] A safe gas stove includes a stove base 9, a burner 8, and a stove base support 7;

[0042] The stove support 7 includes:

[0043] A rectangular frame 71, wherein a bottom groove 72 is provided in the middle of the lower end face of each side of the rectangular frame 71;

[0044] The support assembly 73 is provided in four units. One support assembly 73 is respectively provided on the bottom groove 72 of the frame. The support assembly 73 includes a support housing 1, a swing rocker arm 2, an attitude retainer 3, and a synchronous resistor 4.

[0045] The supporting shell 1 includes a shell base 11. A snap-fit ​​base plate 12 is provided on the outer side of the shell base 11, which is engaged below the frame bottom groove 72. A snap-fit ​​side plate 13 is provided at the stop end of the snap-fit ​​base plate 12, which is engaged with the inner wall of the rectangular frame 71. The supporting shell 1 also includes a narrow-diameter cylindrical cavity 14 disposed within the shell base 11. An upper opening 15 is provided at the center of the upper part of the narrow-diameter cylindrical cavity 14. An anti-rotation insert 16 is provided at the front and rear of the inner wall of the narrow-diameter cylindrical cavity 14. Wide-diameter cylindrical cavities 17 are formed at the front and rear of the narrow-diameter cylindrical cavity 14. Each wide-diameter cylindrical cavity 17 has an end opening 18 at its end. A guide shaft groove 19 is provided along the axial direction on the inner wall of the wide-diameter cylindrical cavity 17. Furthermore, at least three guide shaft grooves 19 are provided, and the guide shaft grooves 19 are evenly distributed along the circumferential inner wall of the wide-diameter cylindrical cavity 17.

[0046] The swing rocker arm 2 is rotatably disposed inside the support housing 1; the swing rocker arm 2 includes a rotatable rotating ring 21 disposed in a narrow-diameter cylindrical cavity 14, a rocker arm plug 22 disposed on the inner wall of the rotating ring 21, an upper connecting plate 23 disposed above the rotating ring 21 and passing through the upper opening 15, and a supporting horizontal plate 24 disposed above the upper connecting plate 23 for supporting the cookware.

[0047] The attitude retainer 3 is disposed within the support housing 1 to maintain the rocker arm 2 in a neutral or deflected attitude. The attitude retainer 3 includes a central sliding tube 31 disposed within the rotating ring 21. Each wide-diameter cylindrical cavity 17 is provided with a limiting retaining ring 32 on the side near the central sliding tube 31, and a return spring 33 is provided on the side of each wide-diameter cylindrical cavity 17 away from the central sliding tube 31. The central sliding tube 31 includes a hollow tube body 311, and is disposed on the hollow tube body 311 and connected to the rocker arm plug. The spiral groove 312 is fitted with a locking end groove 313 at its front and rear ends. The lower end of the hollow tube 311 is provided with an anti-rotation shaft groove 314 for accommodating the anti-rotation insertion rod 16. The locking end groove 313 located in front of the spiral groove 312 is positioned rearward, and the locking end groove 313 located behind the spiral groove 312 is positioned forward. The rocker arm plug 22 is cylindrical, and the radius of the rocker arm plug 22 is greater than the groove depth of the locking end groove 313.

[0048] The synchronous resistor 4 includes:

[0049] The adjusting shaft assembly 41 includes an external threaded rod 411, which passes through an end opening 18, a limiting retaining ring 32, and a central sliding tube 31. A torsion handle 412 is provided in front of the external threaded rod 411, and a limiting turntable 413 is provided behind the external threaded rod 411.

[0050] Two sliding adjustment plates 42 are provided. Each wide-diameter cylindrical cavity 17 is provided with one sliding adjustment plate 42 on the side away from the central sliding tube 31. The sliding adjustment plate 42 includes an internal threaded ring 421 that is slidably disposed in the wide-diameter cylindrical cavity 17 and meshes with the external threaded rod 411, and a guide block 422 disposed on the outer wall of the internal threaded ring 421 and inserted into the guide shaft groove 19.

[0051] The safety gas stove described in this case has a support assembly 73 of its stove stand 7 that can be tilted inward or outward and maintain the tilted posture. Furthermore, it can be tilted inward when cooking with a small pot specifically for infants and toddlers, and outward when cooking with a regular large pot.

[0052] S1, Under normal conditions, the swing arm 2 can temporarily maintain a vertical posture:

[0053] As per the instruction manual Figure 4 , 5 As shown:

[0054] Two reset springs 33, one in front and one behind, compress the corresponding limiting retaining rings 32 so that they abut against the end of the wide-diameter cylindrical cavity 17;

[0055] The centrally located slide tube 31 is restricted within the narrow-diameter cylindrical cavity 14 by two limiting retaining rings 32;

[0056] The spiral groove 312 cooperates with the rocker arm plug 22, so that the swinging rocker arm 2 temporarily maintains a vertical posture.

[0057] S2, move the rocker arm 2 to deflect it inward or outward and maintain the deflection posture:

[0058] S2.1 Deflects outward:

[0059] As per the instruction manual Figure 6 , 7 As shown:

[0060] Move the rocker arm 2 to the right, causing the rotating ring 21 and the rocker arm plug 22 to rotate to the right;

[0061] The rocker arm plug 22 acts on the spiral groove 312 to drive the centering slide tube 31 to slide forward. At the same time, the centering slide tube 31 presses the limiting ring 32 and the reset spring 33 located in front.

[0062] Until the rocker arm plug 22 slides into the locking end groove 313 located at the rear, the reset spring 33 and the limiting retaining ring 32 located at the front give the central slide tube 31 a rearward reaction force, causing the rocker arm plug 22 to be temporarily locked into the locking end groove 313.

[0063] S2.2, Inward deflection:

[0064] Move the swinging rocker arm 2 to the left, causing the rotating ring 21 and the rocker arm plug 22 to rotate to the left;

[0065] Since the radius of the rocker arm plug 22 is greater than the depth of the locking end groove 313, the rocker arm plug 22 can slide out of the locking end groove 313.

[0066] The rocker arm plug 22 acts on the spiral groove 312, thereby driving the centering slide tube 31 to slide backward. At the same time, the centering slide tube 31 disengages from the front limiting ring 32 and the reset spring 33, and begins to press the rear limiting ring 32 and the reset spring 33 backward.

[0067] Until the rocker arm plug 22 slides into the locking end groove 313 located in front, the reset spring 33 and the limiting retaining ring 32 located behind give the central slide tube 31 a forward reaction force, causing the rocker arm plug 22 to be temporarily locked into the locking end groove 313.

[0068] It should be noted that the outward or inward deflection posture can be changed by applying a reverse torsional force, thus allowing for multiple switching. Thanks to the downward pressure exerted on the rocker arm 2 of the support assembly 73 by any cookware placed on the stove support 7, the neutral position of the cookware during normal use will be further stabilized by the inward or outward deflection posture without causing a change in the deflection state.

[0069] The safety gas stove described in this case allows for adjustment of the damping of the reset spring 33 within a certain range, thereby adjusting the damping of the rocker arm 2.

[0070] Rotating the torsion handle 412 and the external threaded rod 411 drives a pair of internal threaded rings 421 to move closer or further apart, adjusting the compression and elasticity of the reset spring 33 under normal conditions, and finally adjusting the damping when the rocking arm 2 is moved.

[0071] It should be noted that the support assembly 73 also includes a posture locking device 5, which includes a locking chamber 51 and a lock cylinder assembly 52.

[0072] The locking chamber 51 passes through the torsion handle 412, the external threaded rod 411, the central fine hole 511 of the limiting disc 413, and the spring chamber 512 located at the torsion handle 412 in the central fine hole 511 from front to back. The front end face of the limiting disc 413 is provided with a receiving groove 513. The rear end face of the outer shell base 11 is provided with fixing locking teeth 514 evenly distributed in the circumferential direction at the corresponding position of the receiving groove 513. The rear end of the receiving groove 513 is evenly distributed with connecting transverse holes 515 in the circumferential direction. The limiting disc 413 is provided with a rear circular hole 516 that communicates with the connecting transverse hole 515.

[0073] The lock cylinder assembly 52 includes a cylindrical spindle 521 disposed in a central fine hole 511. A spring retainer 522 is provided on the portion of the cylindrical spindle 521 located in the spring chamber 512. A compression spring 523 is provided on the cylindrical spindle 521 located behind the spring retainer 522. A rear disc 524 is provided on the portion of the rear end of the cylindrical spindle 521 located in the rear circular hole 516. Sliding locking teeth 525 passing through the connecting transverse hole 515 are evenly distributed around the front end of the rear disc 524. The sliding locking teeth 525 are locked in engagement with the fixed locking teeth 514.

[0074] Thanks to the improved technical solution mentioned above, under normal conditions, the sliding locking tooth 525 acts on the spring retaining plate 522, thereby driving the cylindrical spindle 521, the rear disc 524, and the sliding locking tooth 525 to move forward. The sliding locking tooth 525 acts on the fixed locking tooth 514 to lock the rotational freedom of the adjusting shaft assembly 41, and finally restricts the damping of the reset spring 33 to keep it stable.

[0075] When it is necessary to change the damping of the reset spring 33, pressing the cylindrical spindle 521 backward will disengage the sliding locking tooth 525 from the fixed locking tooth 514, thereby unlocking the rotational freedom of the adjusting shaft assembly 41 and facilitating the adjustment of the damping of the reset spring 34.

[0076] It should be noted that the support housing 1 and the swing arm 2 of the support assembly 73 are made of heat-insulating material to minimize the damage to the internal structure of the support assembly 73 caused by the high temperature of combustion.
