Description

Technical Field

[0001] This utility model relates to the field of container technology, and in particular to a stopper-type kettle. Background Technology

[0002] Currently, kettles or water bottles with stopcocks are very common on the market. They mainly consist of a kettle body, a lid, and a stopcock assembly. The stopcock assembly is installed on the lid, which is then screwed onto the opening of the kettle body. By pressing or rotating the stopcock assembly (i.e., a press-type or rotate-type stopcock assembly), the stopcock assembly and lid are opened, allowing water to be poured without opening the lid, which is convenient. However, most rotary stopcock assemblies on the market require a screw connection, meaning they need to be threaded. The thread length cannot be too long, otherwise it will not only be inconvenient to operate but also create a design conflict with the lid. However, an excessively short thread design also challenges the sealing performance. Therefore, there is an urgent need for a kettle or water bottle with a simple structure, easy operation, and a rotary stopcock assembly. Utility Model Content

[0003] The purpose of this utility model is to design a stopper-type kettle to overcome the shortcomings of the above-mentioned technology.

[0004] This utility model designs a stopcock kettle, including a kettle body, a switch cover, and a stopcock assembly. The kettle body has a spout at the top and a protrusion on the inner wall of the kettle body. The switch cover is fitted onto the spout and has a central mounting hole communicating with the interior of the kettle body. The stopcock assembly is rotatably mounted in the mounting hole. The switch cover includes an upper cover and a lower cover. The inner wall of the upper cover is connected to the stopcock assembly and rotates with the stopcock assembly. The lower cover is connected to the outer wall of the upper cover and has a through hole on its peripheral wall. The stopcock assembly has a telescopic part on its outer periphery. The rear end of the telescopic part is elastically connected to the outer periphery of the stopcock assembly through a first elastic element. The telescopic part is telescopically connected to the through hole. After passing through the through hole, the telescopic part forms an axial limit with the protrusion of the kettle body. Under the action of the first elastic element, the telescopic part is in a normally extended state. At this time, the front end of the telescopic part extends into the through hole, so that the stopcock assembly, the switch cover, and the kettle body are locked.

[0005] The telescopic part is provided with a first inclined surface that tilts backward. A lower pressure sleeve is provided between the lower cover and the stopcock assembly. The top end of the lower pressure sleeve abuts against the bottom end of the upper cover. The top end face of the lower pressure sleeve and the bottom end face of the upper cover form a spiral fit. A second elastic element is provided between the lower pressure sleeve and the lower cover. The bottom inner wall of the lower pressure sleeve is provided with a second inclined surface. When the stopcock assembly rotates, the stopcock assembly drives the upper cover to rotate. The upper cover presses down on the lower pressure sleeve during rotation through the spiral fit. The bottom end of the lower pressure sleeve presses down on the telescopic part. At this time, the second inclined surface of the lower pressure sleeve abuts against the first inclined surface and pushes the telescopic part to retract inward. At this time, the telescopic part separates from the protrusion, so that the stopcock assembly together with the switch cover is in an unlocked state from the kettle body. At this time, the stopcock assembly together with the switch cover can be separated from the kettle body.

[0006] Preferably, the number of telescopic parts is at least two, and they are evenly distributed around the outer circumference of the valve assembly.

[0007] Further optimization includes an outer sleeve rotatably connected to the upper cover, a first sealing ring between the bottom of the outer sleeve and the inner wall of the pot body, and one end of the first elastic element abutting against the outer wall of the outer sleeve; the screw assembly also includes a rotating sleeve, which is fitted inside the outer sleeve, and a limiting relationship is formed between the rotating sleeve and the outer sleeve, the outer sleeve rotates with the rotating sleeve, and a second sealing ring is provided between the rotating sleeve and the outer sleeve.

[0008] Further optimization includes a drive sleeve, a first mounting sleeve, a second mounting sleeve, and a third mounting sleeve. The drive sleeve is fitted onto the rotating sleeve. The first and second mounting sleeves are respectively positioned vertically within the rotating sleeve. An axial first positioning hole is formed in the center of the outer sleeve. The third mounting sleeve is fitted into the first positioning hole, with its top end abutting against the second mounting sleeve. An axial second positioning hole is formed in the center of the third mounting sleeve, penetrating both the second and first mounting sleeves. The valve assembly also includes a temperature sensing mechanism, comprising a sensor and a display element. The sensor is installed in the second positioning hole, with its bottom extending downwards into the body of the vessel. The top of the sensor is connected to the display element, which is mounted on the top of the drive sleeve and positioned above the first mounting sleeve.

[0009] Further optimization involves providing a filter section at the bottom of the outer casing, a third sealing ring between the top port of the filter section and the third mounting sleeve, and extending the top of the sensor downward through the filter section into the kettle body.

[0010] Further optimization involves adding a lid to the spout.

[0011] Further optimization involves providing an annular groove on the top end face of the drive sleeve, embedding a first magnetic element within the annular groove, and providing a second magnetic element within the lid that magnetically attracts the first magnetic element.

[0012] Further optimization involves forming an outward flange at the top of the drive sleeve, and providing a cover at the top of the drive sleeve. The cover is positioned on the top end face of the drive sleeve and covers the first magnetic suction component. The outer edge of the cover is bent and then connected to the flange via a snap-fit.

[0013] The technical advantages of this invention are as follows: by rotating the stopcock assembly, the telescopic part on the outer wall of the stopcock assembly can extend and retract. When the telescopic part extends, it forms a latch with the inner wall of the pot, thus locking the switch cover and the pot spout. When the stopcock assembly is rotated in the opposite direction, the telescopic part is compressed and retracts, separating from the inner wall of the pot. At this time, the switch cover and the pot spout are unlocked, and the switch cover, together with the stopcock assembly, can be opened from the pot spout. Therefore, the opening and closing of the switch cover can be achieved simply by rotating the stopcock assembly, making the operation simple and convenient. The stopcock assembly also includes a temperature sensing mechanism to monitor the temperature inside the pot or the water temperature. The bottom of the stopcock assembly has a filter section, i.e., a tea strainer structure, which makes brewing tea very convenient. The pot lid and the top of the stopcock assembly are locked together by a magnetic attraction, making operation convenient and the structure simple and easy to implement. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0022] This utility model includes a kettle body 1, a switch cover 2, and a stopcock assembly 3. The kettle body 1 has a spout 11 at the top and a protrusion 12 on the inner wall of the kettle body 1. In this embodiment, the kettle body 1 has a double-layer structure, with the outer layer being the kettle body and the inner layer forming the cavity inside the kettle body 1. A cavity is left between the inner and outer layers to form a heat preservation cavity. The protrusion 12 is formed by bending the inner layer. The switch cover 2 is fitted onto the spout 11. The switch cover 2 has a mounting hole 21 in the center that communicates with the inside of the kettle body 1. The stopcock assembly 3 is rotatably installed in the mounting hole 21. When the stopcock assembly 3 rotates, it drives the switch cover 2 to rotate as well. The stopcock assembly 3 unlocks or locks the buckle between itself and the kettle body 1 by rotating.

[0023] Specifically, the switch cover 2 includes an upper cover 22 and a lower cover 23. The stopcock assembly 3 includes an outer sleeve 34, a drive sleeve 38, a first mounting sleeve 39, a second mounting sleeve 310, and a third mounting sleeve 311. The outer sleeve 34 is rotatably connected to the upper cover 22, meaning that the inner wall of the upper cover 22 is connected to the stopcock assembly 3 and rotates with the stopcock assembly 3. The lower cover 23 is connected to the outer wall of the upper cover 22. A through hole 24 is provided on the peripheral wall of the lower cover 23. A telescopic part 3 is provided on the outer periphery of the outer sleeve 34. 1. The rear end of the telescopic part 31 is elastically connected to the outer periphery of the outer sleeve 34 through the first elastic member 32. The telescopic part 31 is telescopically connected to the through hole 24. After the telescopic part 31 passes through the through hole 24, it forms an axial limit with the protrusion 12 of the kettle body 1. The telescopic part 31 is in the normally extended state under the action of the first elastic member 32. At this time, the front end of the telescopic part 31 extends into the through hole 24, so that the outer sleeve 34, i.e. the stopcock assembly 3, together with the switch cover 2, is locked to the kettle body 1.

[0024] The telescopic part 31 is provided with a first inclined surface 33 that tilts backward. A lower pressure sleeve 4 is provided between the lower cover part 23 and the outer sleeve 34. The top end of the lower pressure sleeve 4 abuts against the bottom end of the upper cover part 22. A spiral fit is formed between the top end face of the lower pressure sleeve 4 and the bottom end face of the upper cover part 22. A second elastic element 5 is provided between the lower pressure sleeve 4 and the lower cover part 23. The bottom inner wall of the lower pressure sleeve 4 is provided with a second inclined surface 41. When the stopcock assembly 3 rotates, that is, when the outer sleeve 34 rotates, the outer sleeve 34 drives the upper cover part 22 to rotate. The upper cover part 22 passes through... During the rotation of the spiral fitting, the lowering sleeve 4 is pressed down, and the bottom end of the lowering sleeve 4 presses down the telescopic part 31. At this time, the second inclined surface 41 of the lowering sleeve 4 abuts against the first inclined surface 33. The second inclined surface 41 and the first inclined surface 33 are exactly offset from each other. When pressed down, the telescopic part 31 is pushed to retract inward. At this time, the telescopic part 31 separates from the protrusion 12, so that the stopcock assembly 3 together with the switch cover 2 is in an unlocked state with the kettle body 1. At this time, the outer sleeve 34, i.e., the stopcock assembly 3 together with the switch cover 2, can be separated from the kettle body 1.

[0025] Furthermore, there are at least two telescopic parts 31, which are evenly distributed around the outer periphery of the valve assembly 3. In this embodiment, there are four telescopic parts 31, which are arranged in a cross shape.

[0026] Furthermore, in this embodiment, both the first elastic element 32 and the second elastic element 5 are springs. One end of the first elastic element 32 abuts against the telescopic part 31, and the other end abuts against the outer wall of the outer sleeve 34 through the positioning protrusion 12. The positioning protrusion 12 extends out from the outer wall of the outer sleeve 34, that is, it is integrally connected with the outer sleeve 34. A first sealing ring 35 is provided between the bottom of the outer sleeve 34 and the inner wall of the kettle body 1 to prevent water leakage when the outer sleeve 34 is locked with the kettle body 1.

[0027] The valve assembly 3 also includes a rotating sleeve 36, which is fitted inside the outer sleeve 34. A limiting position is formed between the rotating sleeve 36 and the outer sleeve 34. In this embodiment, a first protrusion 12 is formed on the outer wall of the rotating sleeve 36, and a second protrusion 12 is formed on the inner wall of the outer sleeve 34. The first protrusion 12 and the second protrusion 12 form a limiting position or a snap-fit, so that when the rotating sleeve 36 is driven to rotate, the outer sleeve 34 can rotate with the rotating sleeve 36. A second sealing ring 37 is provided between the rotating sleeve 36 and the outer sleeve 34.

[0028] The valve assembly 3 also includes a drive sleeve 38, a first mounting sleeve 39, a second mounting sleeve 310, and a third mounting sleeve 311. The drive sleeve 38 is sleeved on the rotating sleeve 36. The first mounting sleeve 39 and the second mounting sleeve 310 are respectively positioned vertically and fitted inside the rotating sleeve 36. The outer sleeve 34 has an axial first positioning hole 312 in its center. The third mounting sleeve 311 is fitted inside the first positioning hole 312, with its top end abutting against the second mounting sleeve 310. The third mounting sleeve 311 has an axial second positioning hole 313 in its center, which penetrates both the second mounting sleeve 310 and the first mounting sleeve 39. The valve assembly 3 also includes a temperature sensing mechanism. The device includes a sensor 314 and a display 315. The sensor 314 is installed in the second positioning hole 313, with its bottom extending downwards into the kettle body 1. The top of the sensor 314 is connected to the display 315, which is installed on the top of the drive sleeve 38 and above the first mounting sleeve 39. The sensor 314 serves as a temperature sensing element, used to sense the temperature inside the kettle body 1 or the temperature of the water inside the kettle body 1. The display 315 serves as a control center, typically housing a control board and various sensing components. The display 315 also includes a display screen, on which the temperature measured by the sensor 314 is displayed, allowing the user to know the temperature inside the kettle or the water temperature in real time. Since the temperature sensing mechanism in this embodiment is a conventional technology, its specific structure and operating principle will not be described in detail here.

[0029] Furthermore, the bottom of the outer casing 34 is provided with a filter section 316, which is a tea strainer. The top end of the filter section 316 is connected to the third mounting sleeve 311, and a third sealing ring 317 is provided between the two. The filter section 316 is used to place tea leaves and various other items to be brewed, preventing them from spreading into the pot body 1. A perforation is provided in the center of the bottom end of the filter section 316. The top end of the sensing element 314 passes through the perforation and extends into the pot body 1, so that it does not affect the filtration or the temperature measurement.

[0030] Furthermore, a lid 6 is provided at the spout 11. In this embodiment, the lid 6 has a two-layer structure. An annular groove 318 is provided on the top end face of the drive sleeve 38. A first magnetic attractor 319 is embedded in the annular groove 318. A second magnetic attractor 61 is provided in the lid 6 to form a magnetic attraction with the first magnetic attractor 319. The second magnetic attractor 61 is installed between the two layers of the lid 6, so that the lid 6 can form a magnetic attraction with the spout 11, so that the lid 6 can be directly attracted to the spout 11, which is very convenient.

[0031] Furthermore, the top of the drive sleeve 38 forms an outward flange 320, and the top of the drive sleeve 38 is provided with a cover 321. The cover 321 is disposed on the top end face of the drive sleeve 38 and covers the first magnetic suction member 319. The outer edge of the cover 321 is bent and forms a snap connection with the flange 320, so that the first magnetic suction member 319 can be firmly installed on the drive sleeve 38.

[0032] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
