[0024] The following examples illustrate the present invention, but the present invention is not limited to these examples. Modifications to the specific embodiments of the present invention or equivalent replacements of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed in the present invention.

[0025] Example 1

[0026] See also Figure 1-5 This embodiment provides a double-layer pot stand for use on a gas stove and mounted on the periphery of the burner. The double-layer pot stand comprises a base 1 and a support frame 2. The support frame 2 is mounted on the base 1 and together define an insulating cavity 3. The insulating cavity 3 is used to reduce the conduction of heat absorbed by the support frame 2 to the base 1 and below the base 1, significantly reducing heat loss from the support frame 2 and lowering the temperature rise of the base 1. The base 1 is provided with a plurality of stoppers 11 at intervals, and the support frame 2 is provided with a number of mating portions 21 equal to the number of the stoppers 11. The mating portions 21 engage with the stoppers 11 in a mating manner. Thus, the engagement of the stoppers 11 by the mating portions 21 facilitates quick assembly and disassembly, improving production efficiency.

[0027] It can be seen that the double-layer pot support of this embodiment has a simple structure by providing a limiting portion 11 on the base 1 and adding a matching portion 21 on the support frame 2 to engage the limiting portion 11, which facilitates quick disassembly and assembly, thereby improving production efficiency. In addition, the support frame 2 and the base 1 jointly define the heat insulation cavity 3, which reduces the radiant heat absorbed by the double-layer pot support, reduces the heat conducted from the top of the heat insulation cavity 3 to the bottom, reduces the temperature rise at the base 1, and is conducive to improving the thermal efficiency of the burner.

[0028] See also Figure 1-3Specifically, there are three ways to form the heat insulation cavity 3: in the first scheme, the base 1 is provided with an upper groove 13 opening upward, and the support frame 2 is connected to the base 1 so that the upper groove 13 and the bottom of the support frame 2 jointly define the heat insulation cavity 3; in the second scheme, the support frame 2 is provided with a lower groove 23 opening downward, and the support frame 2 is connected to the base 1 so that the lower groove 23 and the top of the base 1 jointly define the heat insulation cavity 3; in the third scheme, the base 1 is provided with an upper groove 13 opening upward, and the support frame 2 is provided with a lower groove 23 opening downward. When the base 1 and the support frame 2 are assembled, the upper groove 13 is inserted into the lower groove 23 from bottom to top, so that the lower groove 23 cooperates with the upper groove 13 and jointly defines the heat insulation cavity 3. This embodiment takes the third solution as an example to ensure that the insulation cavity 3 has a sufficiently large volume, further improve the insulation effect, further reduce the heat conducted from the support frame 2 to the base 1, and significantly reduce heat loss. At the same time, through the cooperation between the lower groove 23 and the upper groove 13, the support frame 2 is limited in the radial direction to prevent the support frame 2 from radial displacement during use, thereby improving the stability and reliability of the support cookware.

[0029] Specifically, there are at least two limiting portions 11 and at least two matching portions 21. All limiting portions 11 are evenly spaced along the circumferential direction on the inner side of the bottom of the upper groove 13, and all matching portions 21 are evenly spaced along the circumferential direction on the inner side of the top of the lower groove 23, so that both the limiting portions 11 and the matching portions 21 are located inside the heat-insulating cavity 3. The matching portion 21 can move between two adjacent limiting portions 11, that is, the matching portion 21 can rotate with the support frame 2 between two adjacent limiting portions 11, and the matching portion 21 can be engaged with one of the limiting portions 11. In this way, the connection between the base 1 and the support frame 2 is more stable and reliable through the at least two matching limiting portions 11 and matching portions 21. At the same time, the axial rotation of the support frame 2 is limited by the two adjacent limiting portions 11.

[0030] Preferably, the number of the limiting parts 11 and the matching parts 21 in this embodiment are four. One limiting part 11 and one matching part 21 constitute a pair of clip-on structures. Through the four pairs of clip-on structures, the connection between the base 1 and the support seat 2 is more stable and reliable, and at the same time it is convenient for quick disassembly and assembly, thereby improving assembly efficiency and reducing production costs.

[0031] More preferably, the limiting portion 11 is a limiting block in the shape of a "7", that is, the limiting block is composed of a vertical segment 111 and a horizontal segment 112 connected to each other in a "7" shape. The vertical segment 111 can be integrally formed with the bottom of the upper groove 13 to facilitate rapid processing and forming of the limiting portion 11, save connection steps, and enhance the strength of the limiting portion 11 itself, or the lower end of the vertical segment 111 is fixedly connected to the bottom of the upper groove 13 by welding to enhance the connection strength. The matching portion 21 is a positioning block having a positioning groove 211. The positioning block and the inner side of the top of the lower groove 23 can be integrally formed and can also be fixedly connected by welding to ensure the connection strength of the positioning block. When the support frame 2 is assembled with the base 1, the support frame 2 is first placed on the base 1, that is, the lower groove 23 is clamped on the outer surface of the upper groove 13, and then the support frame 2 is rotated circumferentially to make the transverse section 112 of the limit block screw into the positioning groove 211, that is, the positioning groove 211 can be movably sleeved on the outer surface of the transverse section 112 of the limit block. In this way, by rotating the support frame 2 circumferentially, the matching connection between the limiting part 11 and the matching part 21 can be achieved or the clamping relationship between the two can be released. The structure is simple, the assembly or disassembly is simple and quick, and the production cost is low.

[0032] See also Figure 1 and Figure 3-4 Furthermore, it also includes a locking piece 4, and a locking hole 12 is provided on at least one limiting portion 11. The locking hole 12 passes through the bottom or side wall of the base 1, and the locking piece 4 is inserted into the locking hole 12 to prevent the limiting portion 11 from releasing the clamping relationship with the corresponding matching portion 21. In this way, by locking and connecting a locking piece 4 with a limiting portion 11, the circumferential rotation of the support frame 2 can be further restricted, ensuring that the pot support 2 will not have circumferential displacement, and further strengthening the stability and reliability of the connection between the pot support 2 and the base 1. Compared with the solution of fixing with three or more screws, the connection structure and process of the present invention are simple, and the production efficiency is higher.

[0033] Specifically, the locking member 4 of this embodiment is a screw, pin, or locking pin. A locking hole 12 is provided in the transverse section 112 of one of the limit blocks. The upper end of the locking hole 12 does not penetrate the top surface of the transverse section 112, but the lower end penetrates the bottom of the base 1. Thus, when the locking member 4 is inserted into the locking hole 12 from the bottom up, the locking member 4 is securely connected to the transverse section 112 of the limit block, clamping the mating portion 21 between the vertical section 111 and the locking member 4. This prevents the mating portion 21 from dislodging from the transverse section 112, thereby releasing the engagement between the limit portion 11 and the mating portion 21. This further limits the circumferential rotation of the support frame 2, ensuring that the pot support 2 does not experience circumferential displacement, and further strengthening the stability and reliability of the connection between the pot support 2 and the base 1. Furthermore, since the locking member 4 is located at the bottom, the aesthetics of the product's sidewalls are prevented from being affected by the locking member 4.

[0034] See also Figure 1 and Figure 3-4 Specifically, at least three supporting legs 14 extending downward are provided in the circumferential direction of the bottom of the base 1. The locking hole 12 passes through the bottom of the base 1. One of the supporting legs 14 is arranged below the locking hole 12 and has a cavity 141 opening downward. The cavity 141 is connected to the locking hole 12. In this way, the locking member 4 is hidden in the supporting legs 14, further improving the overall aesthetics of the product.

[0035] In this embodiment, there are four supporting feet 14, and the four supporting feet 14 are evenly spaced and connected to the bottom of the base 1 along the circumferential direction, and the four supporting feet 14 are respectively arranged corresponding to the four limiting parts 11 above and below, that is, the four supporting feet 14 are respectively located directly below the four limiting parts 11, which improves the aesthetics of the overall layout of the base and facilitates the supporting feet 14 to provide a certain supporting force to the limiting parts 11 located above them.

[0036] Preferably, each of the four support legs 14 has a downwardly open cavity 141, so that each support leg 14 has a hollow structure, which reduces the overall weight of the base 1, reduces the manufacturing materials, and further reduces production costs. More preferably, each support leg 14 is integrally formed with the base 1, so that the support legs 14 can be quickly processed and formed, saving the process of connecting the support legs 14 to the base 1, and ensuring a secure connection.

[0037] In other embodiments, the locking hole 12 can be set to pass through the bottom of the base 1 and be located on the outside of the support foot 14. In this way, when disassembling and assembling the locking member 4, there is no need to pass through the support foot 14 and turn the base 1 over. At the same time, during processing and manufacturing, there is no need to consider the correspondence between the limit portion 11 and the support foot 14.

[0038] See also Figure 1 and Figure 5 Furthermore, an air intake channel is formed between the lower groove 23 and the upper groove 13. The air intake channel is located radially outside the heat-insulating cavity 3, and both ends of the air intake channel are connected to the atmosphere and the heat-insulating cavity 3, respectively. In this way, the heat-insulating cavity 3 is connected to the external atmosphere radially outside through the air intake channel, so that the external air can convect with the heat in the heat-insulating cavity 3. At the same time, under the action of the air intake channel, the contact area between the support frame 2 and the base 1 is reduced, further reducing the heat conducted from the support frame 2 to the base 1, and significantly reducing the heat loss of the support frame 2.

[0039] Specifically, the outer wall of the upper groove 13 extends into the lower groove 23, leaving a first gap 51 between the outer wall of the upper groove 13 and the outer wall of the lower groove 23, and a second gap 52 between the upper end surface of the outer wall of the upper groove 13 and the top of the lower groove 23. The first gap 51 and the second gap 52 constitute an air intake passage. In this embodiment, a step (not shown) is provided at the upper end of the outer wall of the upper groove 13. A third gap 53 communicating with the air intake passage is left between the horizontal surface of the step and the lower end surface of the outer wall of the lower groove 23. The first gap 51 is defined by the distance between the outer wall of the lower groove 23 and the vertical surface of the step. In this way, the effective contact between the outer wall of the lower groove 23 and the outer wall of the upper groove 13 is reduced, thereby reducing the heat transferred from the outer wall of the lower groove 23 to the outer wall of the upper groove 13, thereby reducing the heat loss of the support frame 2.

[0040] Specifically, the outer wall of the upper groove 13 is provided with a plurality of upwardly extending protrusions 15 at evenly spaced intervals along the circumferential direction. In this embodiment, there are eight protrusions 15, which are evenly spaced along the circumferential direction on the outer wall of the upper groove 13. Each protrusion 15 extends into the lower groove 23 and abuts the top of the lower groove 23, thereby forming a second gap 52 between the upper end surface of the outer wall of the upper groove 13 and the top of the lower groove 23. The second gap 52 is located between two adjacent protrusions 15. As a result, the eight protrusions 15 greatly reduce the effective contact area between the support frame 2 and the base 1, further reducing the heat conducted from the support frame 2 to the base 1, and significantly reducing heat loss from the support frame 2.

[0041] Specifically, a plurality of inwardly extending support platforms 16 are provided at circumferential intervals at the lower end of the inner sidewall of the base 1, and the top surfaces of the support platforms 16 abut against the lower end surface of the inner sidewall of the lower groove 23. Preferably, the height of the inner sidewall of the upper groove 13 is less than the height of the inner sidewall of the lower groove 23. Thus, when the inner and outer sidewalls of the upper groove 13 extend into the lower groove 23 and the top surfaces of the support platforms 16 abut against the lower end surface of the inner sidewall of the lower groove 23, a first gap 61 is left between the upper end surface of the inner sidewall of the upper groove 13 and the top of the lower groove 23, thereby reducing the effective contact area between the inner sidewall of the upper groove 13 and the support frame 2 and reducing heat conduction therebetween. In addition, a second gap may be left between the inner sidewall of the upper groove 13 and the inner sidewall of the lower groove 23. This further reduces the effective contact area between the inner sidewall of the upper groove 13 and the support frame 2, significantly reducing heat conduction therebetween and reducing the temperature rise of the base 1.

[0042] See also Figure 1In this embodiment, the support frame 2 is an energy-gathering disk, so that the top surface 201 of the support frame 2 constitutes an energy-gathering surface. When the double-layer pot bracket is installed on the periphery of the burner, under the action of the energy-gathering surface, on the one hand, the range of the high-temperature flue gas area of ​​the burner is expanded, thereby effectively increasing the temperature of the high-temperature flue gas area and making the gas burn more fully, thereby significantly reducing the emission of CO in the combustion exhaust gas; on the other hand, the heat is gathered at the bottom of the pot, thereby strengthening the convection heat exchange between the high-temperature flue gas and the bottom of the pot, and further improving the thermal efficiency of the burner.

[0043] In addition, at least three pot support plates 22 are evenly spaced along the circumferential direction on the top surface 201 of the support frame 2. The three pot support plates 22 can achieve the purpose of stably supporting the pot. In this embodiment, the number of pot support plates 22 is four, and the four pot support plates 22 are evenly spaced along the circumferential direction and fixedly connected to the top surface 201. Figure 3 Each pot support piece 22 is located directly above the corresponding matching portion 21. In this way, each pot support piece 22 is located above the corresponding supporting foot 14 and the limiting portion 11. That is, a pot support piece 22, the matching portion 21 and the limiting portion 11 that are engaged with each other, and the pot support piece 22 are located on the same vertical plane, which enhances the load-bearing performance of the pot support piece 22 and ensures that the pot support piece 22 can stably support the pot.

[0044] Example 2

[0045] The difference between this embodiment and embodiment 1 is that each supporting leg 14 has a cavity 141 opening downward to reduce the weight of the base 1 and reduce manufacturing materials and production costs. A locking hole 12 is provided on the transverse section 112 of each limit block, and each locking hole 12 passes through the bottom of the base 1 and is connected to the cavity 141 of the supporting leg 14 located therebelow. Other parts are the same as those in embodiment 1.

[0046] The number of locking members 4 in this embodiment is one. During assembly, the support frame 2 is first set on the base 1, and then the support frame 2 is rotated circumferentially to screw the transverse section 112 of the limit block into the positioning groove 211. Finally, a locking member 4 is set from bottom to top in one of the locking holes 12 to securely connect the locking member 4 to the transverse section 112 of the corresponding limit block. During disassembly, one locking member 4 is first removed to allow the support frame 2 to rotate between two adjacent limit blocks. The support frame 2 is then rotated circumferentially to disengage the transverse section 112 of the limit block from the positioning groove 211, thereby releasing the engagement between the limit portion 11 and the mating portion 21. At this point, the support frame 2 can be removed from the base 1.

[0047] It can be seen that by providing a locking hole 12 on the transverse section 112 of each limit block, and each locking hole 12 passes through the bottom of the base 1 and connects to the cavity 141 located therebelow, in this way, when the support frame 2 is assembled with the base 1, a locking member 4 can be selectively fastened to one of the locking holes 12, making the assembly of the locking member 4 simpler and more flexible, and improving production efficiency.

[0048] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all fall within the scope of protection of the present invention.
