Abstract
Description
Technical Field
[0001] This utility model relates to the field of household appliance technology, specifically to an insulated pot lid and a slow cooker. Background Technology
[0002] Slow cookers are modern electric cooking appliances that not only cook food but also have a keep-warm setting. Compared to traditional gas stoves, they are more convenient and hygienic, making them an indispensable household item. Generally, slow cookers offer various cooking modes and allow users to adjust the power to achieve different cooking temperatures.
[0003] However, traditional slow cookers heat up slowly, and during the heating process, most of the heat escapes through the glass lid. The lid gets very hot, which can easily burn the user. Furthermore, when the lid is opened, the hot steam inside the pot sprays directly upwards from the gap between the lid and the pot body, which can also easily burn the user. Utility Model Content
[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to invent a heat-insulating pot lid that can reduce heat loss during the heating process and prevent users from being scalded.
[0005] One of the objectives of this utility model is achieved through the following technical solution:
[0006] A heat-insulating pot lid, comprising,
[0007] The cover includes a first protective layer, a heat insulation layer, a second protective layer and a clamp. The first protective layer, the heat insulation layer and the second protective layer are arranged from top to bottom. The clamp is sleeved on the outside of the first protective layer, the heat insulation layer and the second protective layer and is suitable for connecting the first protective layer, the heat insulation layer and the second protective layer into one piece.
[0008] The barrier includes a body sleeved on the outside of the clamp and a barrier plate extending outward from the body, the barrier being made of an elastic material;
[0009] The handle includes a fixing pin and a handle body. The bottom end of the fixing pin is provided with a limit block, and the top end of the fixing pin passes through the second protective layer, the heat insulation layer and the first protective layer from bottom to top, and the handle body is installed thereon.
[0010] Furthermore, a limiting plate is provided at the bottom of the fixing pin, the top of the limiting plate abuts against the second protective layer, and a gasket is provided between the limiting plate and the second protective layer. The gasket is made of elastic material and is suitable for sealing the gap between the fixing pin and the second protective layer.
[0011] Furthermore, it also includes a locking component, which includes a pin, a mounting base, a toggle plate, and a resilient element. The locking pin is located on the outer side of the inner part of the handle body and has a slot 3021. The handle body has a through hole corresponding to the slot position. The mounting base and the resilient element are mounted on the handle body. The middle part of the toggle plate is rotatably mounted on the mounting base. One end of the pin is located in the through hole and can slide relative to the through hole. The other end of the pin is hinged to one end of the toggle plate. The other end of the toggle plate is fixedly connected to the resilient element. The toggle plate is adapted to rotate around the mounting base under the elastic force of the resilient element to drive the pin to move towards the slot and embed into the slot.
[0012] Furthermore, the body is provided with an annular receiving cavity, and the inner side of the annular receiving cavity is provided with an opening for the clamp to enter, and the clamp is disposed in the annular receiving cavity.
[0013] Furthermore, the cover is provided with vent holes that penetrate the first protective layer, the insulation layer, and the second protective layer.
[0014] Furthermore, the thickness of the barrier plate gradually increases from the outer side to the inner side.
[0015] Furthermore, a flange is formed at the connection between the barrier plate and the body, and the flange fits against the inner side of the pot opening.
[0016] The second objective of this utility model is achieved through the following technical solution:
[0017] A slow cooker includes a pot body having an upper opening and the aforementioned insulated lid, the insulated lid being mounted on the upper opening.
[0018] Beneficial effects:
[0019] By incorporating a heat insulation layer within the lid, heat loss during the slow cooker's heating process is reduced, improving heating efficiency and making cooking more efficient. This also enhances the slow cooker's heat retention. A barrier, made of elastic material, is fitted onto the outside of the lid to better seal the gap between the lid and the slow cooker, further reducing heat loss. When the lid is opened, the hot steam from the slow cooker is blocked by the barrier and guided laterally, rather than spraying directly upwards through the gap, thus preventing hot steam from directly hitting the user's elbow and causing burns. Furthermore, a first protective layer and a second protective layer are installed on both sides of the heat insulation layer, protecting it and preventing the user from being burned by contact with the lid during use.

[0031] like Figure 1-5 As shown, a heat-insulating pot lid includes,
[0032] The cover 10 includes a first protective layer 101, a heat insulation layer 102, a second protective layer 103, and a clamp 104. The first protective layer 101, the heat insulation layer 102, and the second protective layer 103 are arranged from top to bottom. The clamp 104 is sleeved on the outside of the first protective layer 101, the heat insulation layer 102, and the second protective layer 103, and is adapted to connect the first protective layer 101, the heat insulation layer 102, and the second protective layer 103 into one unit.
[0033] The barrier 20 includes a body 201 sleeved on the outside of the clamp 104 and a barrier plate 202 extending outward from the body 201. The barrier 20 is made of an elastic material.
[0034] The handle 30 includes a fixing pin 302 and a handle body 301. The bottom end of the fixing pin 302 is provided with a limit block. The top end of the fixing pin 302 passes through the second protective layer 103, the heat insulation layer 102 and the first protective layer 101 from bottom to top, and the handle body 301 is installed thereon.
[0035] This invention reduces heat loss during slow cooker heating by providing a heat insulation layer 102 inside the lid 10, thereby improving the heating efficiency of the slow cooker and making the cooking process more efficient. It also enhances the slow cooker's heat retention. A barrier 20, made of elastic material, is fitted onto the outside of the lid 10 to better seal the gap between the lid and the slow cooker, reducing heat loss. When the lid is opened, the hot steam inside the slow cooker is blocked by the barrier 202 and guided laterally out, rather than spraying directly upwards from the gap between the lid and the slow cooker, thus preventing hot steam from directly hitting the user's elbow and causing burns. Furthermore, a first protective layer 101 and a second protective layer 103 are provided on both sides of the heat insulation layer 102, protecting the heat insulation layer 102 and preventing the user from being burned by contact with the lid during use.
[0036] Meanwhile, in order to enable the fixing pin 302 to connect the first protective layer 101, the heat insulation layer 102, and the second protective layer 103 into one unit, in this embodiment, a limiting plate 303 is provided at the bottom of the fixing pin 302. The top of the limiting plate 303 abuts against the second protective layer 103, thereby cooperating with the handle body 301 to firmly fix the first protective layer 101, the heat insulation layer 102, and the second protective layer 103 together. In addition, in order to prevent hot steam generated during the heating process from entering the gap between the fixing pin 302 and the first protective layer 101, the heat insulation layer 102, and the second protective layer 103, resulting in heat loss, a gasket is provided between the limiting plate 303 and the second protective layer 103. The gasket is made of elastic material so that it can seal the gap between the fixing pin 302 and the second protective layer 103 when the limiting plate 303 and the second protective layer 103 are pressed together.
[0037] To facilitate the placement of the lid, the opening of the slow cooker body 50 is usually funnel-shaped. In order to allow the barrier 20 to fit better with the slow cooker body 50, in this embodiment, the thickness of the barrier 202 gradually increases from the outside to the inside, thereby better fitting with the funnel-shaped opening of the slow cooker body 50. Alternatively, the length of the barrier 202 can be increased, and a flange can be formed at the connection between the barrier 202 and the body 201. The flange can be embedded in the gap between the lid and the opening of the slow cooker body 50 to improve the sealing between the barrier 20 and the opening of the slow cooker body 50, thereby preventing hot steam leakage and reducing heat loss.
[0038] Furthermore, to facilitate user replacement of the first protective layer 101, heat insulation layer 102, and second protective layer 103 when damaged, as well as replacement and cleaning of the gasket 304, this embodiment also includes a locking component 40. The locking component 40 includes a pin 401, a mounting base 402, a toggle plate 403, and an elastic element 404. The locking pin 302 is located on the outer side of the inner portion of the handle body 301 and has a slot 3021. The handle body 301 has a through hole corresponding to the slot 3021. The mounting base 402 and the elastic element 404 are mounted... Mounted on the handle body 301, the middle part of the actuating plate 403 is rotatably mounted on the mounting base 402. One end of the pin 401 is disposed in the through hole and can slide relative to the through hole. The other end of the pin 401 is hinged to one end of the actuating plate 403. The other end of the actuating plate 403 is fixedly connected to the elastic member 404. The actuating plate 403 is adapted to rotate around the mounting base 402 under the elastic force of the elastic member 404, so as to drive the pin 401 to move towards the slot 3021 and embed into the slot 3021.
[0039] In use, the user only needs to press the toggle plate 403 to drive the pin 401 to move away from the slot 3021. The pin 401 separates from the slot 3021. At this time, the fixing pin 302 can be removed, and then the clamp 104 can be opened to replace or repair the first protective layer 101, the heat insulation layer 102, the second protective layer 103 or the gasket 304. After the repair is completed, the fixing pin 302 only needs to be inserted back in, and the pin 401 will be re-embedded into the slot 3021 under the drive of the toggle plate 403.
[0040] To facilitate the repositioning of the retaining pin 302, in this embodiment, a bevel is provided at one end of the pin 401 near the slot 3021. When the retaining pin 302 is repositioned, the top end of the retaining pin 302 will contact the bevel on the pin 401, causing the pin 401 to move towards the through hole until the retaining pin 302 passes the pin 401. At this point, the pin 401 will abut against the outer side of the retaining pin 302 until the slot 3021 and the pin 401 are aligned. Under the elastic force of the elastic element 404, the handle body 301 is inserted into the slot 3021, completing the connection between the handle body 301 and the fixing pin 302. In addition, a protrusion or groove can be provided on the surface of the fixing pin 302, and a matching groove or protrusion can be provided on the contact surface between the first protective layer 101, the heat insulation layer 102, the second protective layer 103 and the fixing pin 302 to guide the fixing pin 302, thereby facilitating the alignment of the slot 3021 with the slot 3021 when the fixing pin 302 is inserted.
[0041] In addition, to prevent heat from escaping through the clamp 104, an annular cavity is provided inside the body 201 in this embodiment. An opening is provided on the inner side of the annular cavity for the clamp 104 to enter. The clamp 104 is disposed in the annular cavity so that the barrier 20 can wrap around the clamp 104 to prevent heat loss. In this embodiment, the body 201 and the barrier plate 202 are integrally formed and are both made of silicone with good heat insulation effect.
[0042] Meanwhile, to facilitate pressure relief, in this embodiment, the cover 10 is provided with a vent hole that penetrates the first protective layer 101, the insulation layer and the second protective layer 103.
[0043] This utility model also discloses a slow cooker, including a pot body 50 with an upper opening and the aforementioned heat-insulating pot lid, wherein the heat-insulating pot lid is installed on the upper opening.
[0044] By providing a heat insulation layer 102 inside the lid 10, heat loss during the slow cooker heating process can be reduced, improving the slow cooker's heating efficiency and making the cooking process more efficient. At the same time, the slow cooker's heat retention effect is enhanced. The barrier 20, which is made of elastic material and is fitted on the outside of the lid 10, can replaceably seal the gap between the lid and the slow cooker to reduce heat loss. When the lid is opened, the hot steam inside the slow cooker will be blocked by the barrier 202 when it is ejected, and will be guided by the barrier 202 and discharged laterally, instead of being directly ejected upward from the gap between the lid and the slow cooker, thereby preventing hot steam from directly spraying onto the user's elbow and causing burns. In addition, a first protective layer 101 and a second protective layer 103 are provided on both sides of the heat insulation layer 102. On the one hand, they can protect the heat insulation layer 102, and on the other hand, they can prevent the user from being burned by contact with the lid during use.
[0045] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
