Description

Technical Field

[0004]

[0001] The present invention relates to the technical field of daily necessities, and particularly to a heat-preserving pot with a handle-equipped lid and a central push button for preventing ejection and incorrect assembly.

Background Art

[0002] Conventionally, heat-preserving pots with push-button lids have excellent heat-preserving performance and are widely used. A screw-in structure is often used for the lid and the pot body. The heat-preserving pot with a handle-equipped lid and a central push button has the characteristics of a novel structure and convenient use, and is deeply favored by consumers. In order to meet the characteristic of convenient use, the heat-preserving pot with a handle-equipped lid and a central push button often adopts a locking method by switches on both sides, which is different from the screw-in structure of 360° rotary fastening. The heat-preserving pot with a handle-equipped lid and a central push button is locked only on both sides, and other parts are likely to loosen. When the pot body is filled with high-temperature drinks, the high-temperature and high-pressure water vapor in the pot body is likely to eject from other parts that are not locked by the switch. At the same time, a general heat-preserving pot with a handle-equipped lid and a central push button requires alignment during assembly with the pot body, and incorrect assembly is likely to occur due to misalignment, which may greatly affect the user experience of consumers. Therefore, there is a need for a heat-preserving pot with a handle-equipped lid and a central push button that can prevent ejection and incorrect assembly.

Summary of the Invention

Problems to be Solved by the Invention

[0003] An object of the present invention is to provide a heat-preserving pot with a handle-equipped lid and a central push button that has a simple structure and can prevent ejection and incorrect assembly.

Means for Solving the Problems

[0004] The thermos according to the present invention includes a pot body with a spout at the top, a top lid, a slide switch, a central push-button switch, and a lid with a handle that includes an inner stopper connected to the top lid, a combination-type sealing ring provided at the bottom of the inner stopper, and an annular projection and an extension formed at the upper and lower parts of the combination-type sealing ring, respectively, so that when the lid with a handle is connected to the spout, the annular projection makes a tight seal against the inside of the spout, and under the thrust of the side of the annular projection, the top lid can be inserted into the spout in a balanced manner and the top lid can be stabilized, and the extension makes a tight seal against the convex rib on the inner wall of the spout. The inner wall of the opening is provided with a positioning lock that engages with the slide switch, an annular step is provided above the inner stopper, the annular step has a positioning passage that engages with the positioning lock, the lock pin of the slide switch is placed in the positioning passage, a water outlet guide groove wall is provided on the inner wall of the opening corresponding to the spout, and the shape of the side portion of the annular step corresponding to the water outlet guide groove wall conforms to the water outlet guide groove wall. In a thermos configured in this way, if the slide switch on the inner stopper is not aligned with the snap-fit ​​portion of the opening, the inner stopper cannot enter the opening, thereby ensuring the uniqueness of the assembly direction of the lid with handle and the spout and preventing incorrect assembly. [Effects of the Invention]

[0005] Therefore, the thermos pot according to the present invention has a simple structure and is easy to assemble. The design of the combination-type sealing ring and the annular stepped section prevents spillage and also prevents incorrect assembly.

[0006] Specifically, the upper part of the combination sealing ring is provided with an annular projection, which prevents high-temperature, high-pressure water from spraying out from both sides that are not locked by the switch, and also helps maintain the balance of the top lid. In addition, the extension provided at the bottom of the combination sealing ring can seal with the convex ribs on the inner wall of the opening, further preventing spraying.

[0007] Furthermore, an annular step with a positioning passage is provided above the inner stopper, and the positioning passage engages with the positioning lock of the opening, and the lock pin of the slide switch is provided within the positioning passage. If the positioning passage in the inner stopper is not aligned with the positioning lock of the opening, the inner stopper cannot enter the opening due to the restriction by the annular step. In addition, a water outlet guide groove wall is provided on the inner wall of the opening, and the annular step has a side surface that matches the shape of the water outlet guide groove wall. If the water outlet guide groove wall and the side surface of the annular step do not match, the inner stopper cannot enter the opening and be assembled. Thus, with the above structure, the lid with a handle can only be assembled on the opening when the water outlet guide groove wall and the side surface of the annular step match each other, and the positions of the positioning passage and the positioning lock correspond. After assembly, it is ensured that the water outlet and spout of the inner stopper correspond, preventing incorrect assembly.

[0008] According to one preferred embodiment of the present invention, two or more annular projections are provided and are spaced apart on the upper part of the combination seal ring.

[0009] According to one preferred embodiment of the present invention, two positioning locks are provided, and the two positioning locks are arranged symmetrically.

[0010] Furthermore, each positioning lock is provided with one stopper rib on each side, the width between the two stopper ribs of each positioning lock matches the width of the positioning passage in the inner plug, and the distance between the stopper ribs of the two positioning locks is smaller than the inner diameter of the annular step.

[0011] According to one preferred embodiment of the present invention, a guide slope is provided on the side of the positioning passage closest to the inner plug.

[0012] Further advantages, features, and potential applications of the present invention can be derived from the description of embodiments shown below in conjunction with the drawings. [Brief explanation of the drawing]

[Figure 2] Figure 1 is a partial cross-sectional view of the pot body and spout of a thermos pot. [Figure 3] Figure 1 is a cross-sectional view of a thermos with a lid and handle connected to the opening. [Figure 4] This is an enlarged schematic view of portion A in Figure 3. [Figure 5] Figure 1 is a schematic diagram of the thermos in its exploded state. [Figure 6] This is a plan view of the lid with a handle and the opening. [Figure 7] This is a diagram showing the usage of a thermos pot according to one embodiment of the present invention. [Modes for carrying out the invention]

[0014] The present invention will be described in more detail below with reference to the drawings.

[0015] Figure 1 shows a thermos pot according to one embodiment of the present invention, which includes a lid with a handle 100, a spout 200 detachably connected to the lid with a handle 100, and a pot body 300 airtightly connected to the spout 200.

[0016] As shown in Figures 2 to 5, the lid with a handle 100 includes a top lid 101, a slide switch 102, a central push-button switch 103, and an inner plug 104 with a combination sealing ring 105 attached to its bottom. The slide switch 102 is attached to the top lid 101, and a through hole is provided in the center of the top lid 101. The top lid 101 and the inner plug 104 are connected by a snap-fit ​​section, and after they are connected, the central push-button switch 103 is positioned inside the through hole in the top lid. The outer edge 116 of the T-rod 115 abuts against the bottom of the combination sealing ring 105 to seal it.

[0017] Annular projections 106 and downward-facing extensions 107 are formed on the upper and lower parts of the combination-type sealing ring 105, respectively. When the lid with handle 100 is connected to the opening 200, the annular projections 106 adhere tightly to the inside of the opening to seal it, and the extensions 107 adhere tightly to the convex ribs 201 on the inner wall of the opening to seal it. Preferably, two annular projections 106 are provided at intervals on the upper part of the combination-type sealing ring. The annular projections 106 and extensions 107 are integrally molded with the body of the combination-type sealing ring. Because the combination-type sealing ring is provided with annular projections 106, it adheres tightly to the inner wall of the opening 200, making the connection of the lid with handle 100 more stable and preventing rattling. At the same time, airtightness between the inner stopper and the opening is ensured, preventing high-temperature, high-pressure steam from being ejected from areas not locked by the switch inside the pot body.

[0018] A spout 206 is provided in the opening 200. A positioning lock 202 that engages with a slide switch 102 is provided on the inner wall of the opening 200. Two of the positioning locks 202 are provided and are arranged symmetrically to each other. An annular step 108 is provided above the inner stopper 104, and a positioning passage 109 that engages with the positioning lock 202 is drilled in the annular step 108, and the lock pin 111 of the slide switch 102 is placed in the positioning passage 109. Preferably, a guide slope 119 is provided at the entrance of the positioning passage 109, i.e., on the side closer to the inner stopper 104, so that the positioning passage and the positioning lock 202 can be quickly aligned by the guide slope.

[0019] Preferably, as shown in FIGS. 5 and 6, one stopper rib 203 is provided on each side of the positioning lock 202. The width A1 between the two stopper ribs 203 on the same positioning lock 202 is slightly smaller than the width A2 of the positioning passage 109, and the distance D1 between the stopper ribs 203 on the two positioning locks 202 is smaller than the inner diameter of the annular step portion 108. By designing the two stopper ribs, it can function as a guide and position limit for the positioning passage, and can prevent the downward movement of the annular step portion when the positions do not match.

[0020] Further, a water outlet guide groove wall 207 is further provided on the inner wall corresponding to the pouring spout of the mouth portion 200. The shape of the side surface 118 corresponding to the water outlet guide groove wall of the annular step portion 108 conforms to the water outlet guide groove wall, that is, the shapes of the side surface of the annular step portion and the water outlet guide groove wall match each other. By designing like this, the water outlet guide groove wall 207 and the side surface of the annular step portion match each other, and only when the position of the positioning passage 109 and the positioning lock 202 corresponds, the handle lid 100 can be assembled to the mouth portion 200, that is, the assembly direction of the handle lid 100 and the mouth portion 200 is unique, and it is ensured that the water outlet of the inner plug after assembly corresponds to the pouring spout, preventing misassembly.

[0021] During assembly, when the handle lid 100 is pushed down onto the mouth portion 200, the edge of the annular protrusion 106 slides downward while closely contacting the inner wall of the mouth portion 200. However, the slide switch 102 on the inner plug slides over the convex rib 201 of the mouth portion and into the locking groove 204 by means of the built-in telescopic spring 112, locking the lock pin 111 in the locking groove 204, and realizing the operation of assembling the handle lid 100 to the mouth portion 200.

[0022] By adopting the structure of the present invention, after the handle lid 100 is connected to the mouth portion 200, the airtightness is good. When the pot is filled with a high-temperature drink 400, as shown in FIG. 7, no matter how the pot body 300 tilts or shakes, no water vapor will spout out.

[0023] Although the above has described only the technical solutions of the present invention, those skilled in the art will know that simple modifications or equivalent substitutions to the technical solutions of the present invention do not deviate from the substance and scope of the technical solutions of the present invention.
