Description

Technical Field

[0001] The utility model relates to the technical field of non-stick pans, in particular to a non-stick pan with a three-layer pot body. Background Art

[0002] At present, the forming and manufacturing of non-stick pans is to carry out surface treatment on the top surface of the bottom of the pan to form a non-stick layer, so that it has the effects of not easily adhering oil stains on the surface and being easy to clean. For example, carrying out surface treatment of Teflon on the top surface of the bottom of a metal pan can make the top surface of the bottom of the pan have the material characteristics of Teflon, so as to achieve the effects of non-stick and easy to clean. After retrieval, the prior art (publication number: CN210043752U) records "an energy-saving non-stick pan with a three-layer steel pot body. An inner stainless steel layer is provided on the inner side of the pot body, an outer stainless steel layer is provided on the outer side of the pot body, honeycomb-shaped protrusions are provided on the outer side of the inner stainless steel layer, a non-stick layer is provided on the outer side of the inner stainless steel layer, arc-shaped grooves are evenly provided on the outer side of the outer stainless steel layer, a circular protrusion is provided at the bottom of the outer stainless steel layer, and arc-shaped protrusions are evenly provided on the inner side of the circular protrusion. Through the setting of the arc-shaped grooves, when the flame burns and cooks the non-stick pan, the fire will rotate and rise along the outer stainless steel layer, so that the contact time of the flame with the non-stick pan is prolonged, the gas utilization rate is improved, and energy is saved; when the non-stick pan is placed on the table, a plurality of circular protrusions can play an anti-slip role, and at the same time, the contact area between the non-stick pan and the table is reduced, preventing the table from being damaged due to high temperature."

[0003] Although the energy-saving non-stick pan with a three-layer steel pot body in the prior art realizes the effects of energy saving and anti-slip, there are still some deficiencies: Although the inner bottom of the existing non-stick pan with a three-layer steel pot body realizes the non-stick effect, during long-term use, the bottom of the pan is most likely to come into contact with a metal spatula or be scrubbed and rubbed by a steel wool ball, which will cause the structure of the non-stick layer to be damaged. Therefore, it needs to be replaced as a whole, resulting in an increase in the use cost. At the same time, the handle of the existing non-stick pan is connected to the pot body by riveting. Due to the point-surface connection method, the connection firmness is poor. Due to the influence of thermal expansion and contraction, the handle is prone to breakage during use. Summary of the Utility Model

[0004] In order to overcome the defects existing in the prior art, the present utility model provides a non-stick pan with a three-layer pot body to solve the problems that the existing non-stick pan with a three-layer steel pot body has a relatively large use cost and the connection firmness between the handle and the pot body is poor.

[0020] Referring to Figures 1 to 4 As shown, the present utility model provides a non-stick pot with a three-layer pot body, including: a pot body 1 and a pot handle 2. The inner bottom of the pot body 1 is provided with a non-stick pot bottom 11, and a heat-conducting bottom 12 is connected to the lower side of the non-stick pot bottom 11. The non-stick pot bottom 11 is embedded on the upper side of the heat-conducting bottom 12. An integral stainless steel outer layer 13 is provided on the outer edge of the upper side of the heat-conducting bottom 12. An aluminum alloy middle layer 14 is provided inside the stainless steel outer layer 13, and a stainless steel inner layer 15 is provided inside the aluminum alloy middle layer 14. The pot handle 2 includes a riveting hoop 21 connected to the outer wall of the pot body 1. A handle rod 23 is connected to the outside of the riveting hoop 21, and an anti-scald sleeve 24 is sleeved on the outside of the handle rod 23. The riveting hoop 21 is set as two semi-ring structures, and the end opposite to the handle rod 23 of the riveting hoop 21 is set as an open end, and an inner embedded ring 22 is provided on the inner wall of the riveting hoop 21.

[0021] In this embodiment, the pot body 1 and the pot handle 2 constitute the main body structure of the non-stick pot with a three-layer pot body involved in this application.

[0022] Specifically, the heat-conducting bottom 12 and the stainless steel outer layer 13 and the stainless steel inner layer 15 are set as an integral structure, and the heat-conducting bottom 12 is made of high-purity aluminum alloy heat-conducting material.

[0023] Specifically, the anti-scald sleeve 24 is made of rubber material, and anti-slip particles are provided on the surface of the anti-scald sleeve 24.

[0024] Specifically, symmetric annular groove cavities are provided on the outer wall of the pot body 1 and are engaged with the embedded ring 22 in a matching manner. At the same time, the riveting hoop 21 protrudes outside the outer wall of the pot body 1, and the riveting hoop 21 is riveted to the pot body 1 through multiple groups of rivets.

[0025] As Figure 2 and Figure 3 shown, an anti-stick coating 16 is provided on the inner wall of the stainless steel inner layer 15, and the bottom of the stainless steel inner layer 15 is connected to the outer edge of the non-stick bottom 11. The non-stick bottom 11 includes a stainless steel base layer, and a non-stick coating and honeycomb-shaped protrusions are provided on the upper side of the stainless steel base layer. A connecting block 111 is provided on the outer edge of the non-stick bottom 11, and a threaded hole 112 is provided on the outer side of the connecting block 111.

[0026] Specifically, the anti-stick coating 16 is made of Teflon material. The anti-stick coating 16 is located on the inner side wall of the pot body 1. Therefore, during daily use, the frequency of collision and wear with utensils such as metal spatulas is relatively low. Therefore, when most non-stick pans in the prior art are scrapped due to use, most of the reasons are that the non-stick coating material at the bottom of the pan is damaged. Therefore, in this application, the installation method of the non-stick bottom 11 is mainly improved.

[0027] Specifically, the connecting blocks 111 are arranged at equal intervals in the circumferential direction of the non-stick bottom 11, and the connecting blocks 111 are made of high-temperature resistant materials. At the same time, the outer edge of the non-stick bottom 11 is provided with a silicone rubber sealing ring, so that after the heat conduction bottom 12 is installed, the silicone rubber sealing ring can fill the connecting gap.

[0028] As Figure 2 and Figure 3 shown, an embedding groove 121 is provided on the upper side of the heat conduction bottom 12, and a connecting hole 123 extending to the outer wall of the heat conduction bottom 12 is provided on the inner wall of the embedding groove 121. A high-temperature resistant bolt 122 is provided in the connecting hole 123. The outer end of the connecting hole 123 is provided with a countersunk hole, and the inner end of the connecting hole 123 corresponds to the position of the threaded hole 112. At the same time, the high-temperature resistant bolt 122 is connected to the threaded hole 112 in a matching manner.

[0029] As a preferred implementation method, by providing multiple groups of high-temperature resistant bolts 122 on the outer periphery of the heat conduction bottom 12, it is convenient to fix the non-stick bottom 11.

[0030] When in use, by means of the connecting blocks arranged inside the non-stick pot bottom and the threaded holes opened on the outer walls of the connecting blocks, and at the same time through the embedding grooves opened on the upper side of the heat-conducting bottom and the connecting holes opened and communicated on the outer sides of the embedding grooves, it is convenient to fix the non-stick pot bottom in the embedding grooves through high-temperature-resistant bolts. Similarly, after the non-stick pot bottom is damaged after long-term use, it can be disassembled by removing the high-temperature-resistant bolts and then replaced separately, thus avoiding replacing the entire non-stick pan, achieving the effect of reducing the use cost; by means of the riveting hoop and the inner embedded ring included in the pot handle, the inner embedded ring is clamped in the arc-shaped groove opened on the outer wall of the pot body, and then the riveting hoop is fixed on the outer wall of the pot body through rivets, so that by increasing the riveting area between the riveting hoop and the pot body and by setting the riveting hoop and the pot handle as an integrated structure, the connection firmness between the pot handle and the pot body is improved.

[0031] The non-stick pan with a three-layer pot body of the present utility model can effectively solve the problems that the existing non-stick pan with a three-layer steel pot body has a relatively large use cost and the connection firmness between the pot handle and the pot body is relatively poor. On the basis of the existing non-stick pan technology with a three-layer pot body, it is convenient to separately replace the non-stick pot bottom of the non-stick pan, thereby reducing the use cost, and strengthening the connection firmness between the pot handle and the pot body, preventing the phenomenon of the handle breaking due to the thermal expansion and contraction of the metal during long-term use.
