Description

Technical Field

[0001] This utility model relates to the field of thermos flask technology, and more specifically to a household thermos flask. Background Technology

[0002] Most household thermos flasks on the market currently use rotary switches or buttons to control the water dispensing, but this design has several drawbacks. For example, some thermos flasks have simple push-button or rotary switch structures, which may not accurately control the water flow with a single press, leading to leaks or overflows. Furthermore, the seal between the spout and the drive mechanism in existing designs is not tight enough, potentially causing dripping after prolonged use, affecting safety and user experience. Some thermos flasks also have cumbersome operation steps, requiring multiple rotations or presses to open or close the spout, posing a scalding risk, especially when pouring hot water. Additionally, the connection between the spout, handle, and body is not secure enough, making them prone to loosening or damage over time. Therefore, it is necessary to provide a household thermos flask that is easy to operate, safe, reliable, well-sealed, and has excellent heat retention to address the shortcomings of existing technology. Utility Model Content

[0003] In view of this, the present invention provides a household thermos.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A household thermos includes a body assembly and a lid assembly. The body assembly includes a body, a bottom lid, and a water outlet. The water outlet has a spout and a water outlet channel communicating with the spout. The lid assembly includes an inner plug, which is threaded into the water outlet. The inner plug has an inner channel, which, after installation, connects with the water outlet channel. The lid assembly includes a water outlet control mechanism, which includes a T-shaped component that can be sealed or unsealed with a waterproof silicone ring. The lid assembly also includes a button assembly, which is kinetically connected to the water outlet control mechanism and drives the T-shaped component to move. When the T-shaped component moves downward, it separates from the waterproof silicone ring, allowing water to enter the inner channel from the bottom of the inner plug and flow out through the water outlet channel and the spout. When the T-shaped component moves upward, it seals against the waterproof silicone ring, preventing water from flowing out.

[0006] In a preferred embodiment, the button assembly includes a button body and an emblem, which are connected to a rotating component via a bottom sleeve. Together with the top cover, inner plug, cylindrical positioning component, spring, T-shaped component, O-ring, washer, and waterproof silicone ring, the top cover assembly is formed, thereby driving the water outlet control mechanism and forming an operable integrated structure.

[0007] In the preferred embodiment, the rotating component is embedded in the cylindrical positioning component, and the inner wall of the cylindrical positioning component is provided with an array of inclined grooves and vertical grooves. The three protrusions of the rotating component cooperate with it to form a locking mechanism similar to a press-type ballpoint pen, so that the button assembly can achieve a cycle of water output and water sealing after each press.

[0008] In a preferred embodiment, the top of the T-shaped component has a columnar portion that passes through the receiving groove of the inner plug and is connected to the rotating component, and the bottom outer edge is provided with an outer rim, which is used to form a seal by fitting the lower surface of the waterproof silicone ring during resetting.

[0009] In a preferred embodiment, the spring is sleeved on the columnar portion of the T-shaped component, with its lower end abutting against the O-ring and washer, providing a downward restoring force for the T-shaped component.

[0010] In a preferred embodiment, the O-ring and washer are installed at the bottom of the groove of the inner plug to seal the columnar part of the T-shaped part and prevent water from seeping into the mating space between the rotating part and the cylindrical positioning part.

[0011] In a preferred embodiment, the kettle body assembly further includes a first welded component, a second welded component, and a third welded component. The first welded component is welded to the top of the kettle body and engages with the bottom positioning groove of the water outlet component. The second and third welded components are vertically welded along the kettle body for connection to the handle.

[0012] In a preferred embodiment, the horizontal portions of the second and third welded parts extend outward and are provided with screw holes, and the inner sides of both ends of the handle are provided with corresponding grooves and screw holes, which are fixedly connected to the welded parts by screws.

[0013] In the preferred embodiment, the kettle body has a hollow structure and a vacuum layer for heat preservation; the bottom cover is pressed into the bottom of the kettle body by an interference fit for drop protection.

[0014] As can be seen from the above technical solution, compared with the prior art, the present invention has the following beneficial technical effects:

[0015] The kettle features a resettable push-button control for water dispensing; a single press pours water, and a second press closes the spout, making operation simple and safe. A T-shaped component works in conjunction with a waterproof silicone ring, and a locking structure between the rotating component and the cylindrical positioning component allows for half-press / full-press positioning, ensuring a leak-proof spout when closed. The inner plug's internal channel connects to the water outlet channel, clearly defining the water flow path and controlling the water volume to prevent overflow and dripping. Welded components secure the water outlet and handle, and the button assembly and rotating component fit tightly together, resulting in a stable overall structure that is not easily loosened or damaged. The kettle body features a hollow vacuum layer design, and the bottom lid provides drop protection, effectively extending the hot water retention time and improving safety. No multiple rotations or complicated steps are required during operation, making hot water easy to pour and reducing the risk of scalding. Attached Figure Description

[0024] Please see Figure 1-3 A household thermos includes a body assembly C3, a lid assembly B2, and a button assembly A1. The body assembly C3 includes a body 17, a bottom lid 18, a water outlet 5, and welded components. The body 17 is made of stainless steel and has a hollow structure, forming a vacuum layer inside for heat preservation. The bottom lid 18 is press-fitted into the bottom of the body 17 for drop protection. The water outlet 5 is fitted onto the upper part of the body, hollow in the center, forming a spout 5a and a water outlet channel 5b for water flow. A first welded component 14 is welded to the top of the body 17 and engages with the bottom positioning groove of the water outlet 5; a second welded component 15 and a third welded component 151 are vertically welded along the body 17 to fix a handle 16; the horizontal portion extends outward and has screw holes for screw connection to the handle 16. The handle 16 has grooves and screw holes on the inner sides of both ends, allowing it to be fixed to the welded components 15 and 151 with screws.

[0025] Furthermore, the upper cover assembly B2 includes an upper cover 3, an inner plug 4, a waterproof silicone ring 12, a T-shaped component 13, and a rotating component 6. The inner plug 4 is threaded into the water outlet component 5, and its upper end is fixed to the kettle body assembly. The inner plug has an internal channel 4a, which aligns with the water outlet channel 5b after installation. The waterproof silicone ring 12 is fitted onto the outer bottom of the inner plug 4 to form a seal with the T-shaped component 13. The top of the T-shaped component 13 has a columnar portion that passes through the receiving groove of the inner plug 4 and connects to the rotating component 6. The outer edge of the bottom has an outer rim to fit the waterproof silicone ring 12 and achieve a seal. The rotating component 6 is embedded in the cylindrical positioning component 19, with three protrusions on its outer side. The inner wall of the cylindrical positioning component 19 has three evenly distributed oblique and vertical grooves, forming a locking mechanism similar to a press-type ballpoint pen, which enables the positioning and reset of the button assembly A1 after it is pressed down. Spring 8 is sleeved on the cylindrical part of the T-shaped component, with its lower end abutting against O-ring 10 and washer 9, providing downward repositioning force for the T-shaped component. O-ring 10 and circular washer 9 are installed at the bottom of the groove of inner plug 4 to seal the cylindrical part of the T-shaped component, preventing water from seeping into the mating space between rotating component 6 and cylindrical positioning component 19. Cylindrical positioning component 19 is hollow and cylindrical, with an internal inclined groove that mates with the convex part of rotating component to achieve pressing positioning and repositioning.

[0026] Furthermore, the button assembly A1 includes a button body 1 and a badge 2, which are fitted onto the rotating component 6 via a bottom sleeve. The button assembly body and the rotating component 6 are connected by a transmission, but the button can be pressed down, causing the rotating component to move accordingly. The spring 8 provides a restoring force, causing the button to spring back up. The bottom outer edge of the button assembly has an outer edge that forms a locking groove with the top cover 3, and it cannot be pulled out under normal circumstances; it can only be operated by pressing up and down.

[0027] Furthermore, the water outlet control mechanism mainly consists of a T-shaped component 13, a waterproof silicone ring 12, a rotating component 6, a cylindrical positioning component 19, and a spring 8. Its working principle is as follows: When the user presses and immediately releases the button assembly A1: the button pushes the rotating component 6 to move, causing the T-shaped component 13 to move downwards, releasing the seal of the waterproof silicone ring 12, allowing water to enter the inner channel 4a from the bottom of the inner plug 4, and then flow through the water outlet channel 5b to the spout 5a for pouring. After releasing the button, the rotating component 6 and the T-shaped component 13 automatically reset under the action of the spring 8, but the rotating component engages with the inclined groove of the cylindrical positioning component 19 to ensure that the T-shaped component remains in the pouring state. Pressing and releasing the button assembly A1 again: the rotating component 6 moves the T-shaped component 13 upwards to a sealing position completely fitted with the waterproof silicone ring 12, closing the water outlet. The user can repeatedly press the button as needed to achieve a cycle of water outlet and sealing operation. Each action relies on the inclined groove locking mechanism of the rotating component 6 and the cylindrical positioning component 19 to control the position of the T-shaped component 13.

[0028] Furthermore, the specific installation method is as follows: the button assembly A1 is installed on the rotating part 6 via a sleeve, and the outer edge is snapped into the upper cover 3 to form a fixed position. The inner plug 4 is screwed into the water outlet part 5 through threads, ensuring that the inner channel 4a is aligned with the water outlet channel 5b. The T-shaped part 13 and the waterproof silicone ring 12 are assembled at the bottom of the inner plug, the spring 8 is sleeved on the columnar part of the T-shaped part, and the O-ring 10 and the washer 9 are installed at the bottom of the groove. The first welded part 14, the second welded part 15, and the third welded part 151 are welded to the kettle body 17 to fix the water outlet part 5 and the handle 16. The bottom cover 18 is pressed into the bottom of the kettle body to complete the overall installation.

[0029] Furthermore, the specific usage method is as follows: Pour an appropriate amount of boiling water into the kettle body 17. The user presses and releases button assembly A1, causing T-shaped part 13 to move down, releasing the seal of waterproof silicone ring 12, and water flows out of spout 5a from inner channel 4a and water outlet channel 5b. Pressing and releasing button assembly A1 again causes T-shaped part 13 to move up and fit against waterproof silicone ring 12, closing the water outlet. The button can be pressed repeatedly as needed to achieve water flow and sealing circulation. The T-shaped part 13 and waterproof silicone ring 12 provide a reliable seal, preventing accidental water leakage. Button controls the rotating part 6 for automatic positioning and reset, making pouring water easy. The kettle body features a hollow vacuum layer design, and the bottom lid is drop-proof.

[0030] The welded parts secure the handle and water outlet, making the whole unit stable and durable.
