Description

Technical Field

[0001] This utility model relates to the technical field of kettles and kettle accessories, specifically a kettle spout valve and kettle structure. Background Technology

[0002] Kettles are common tools for boiling and storing water in daily life, especially in homes and offices. Traditional kettles typically consist of a body, spout, and handle. The spout, as the channel for pouring water, directly affects the ease of use and safety.

[0003] Most kettles on the market today have an open spout design, meaning the front of the spout is open, allowing liquid to flow freely. While this design is convenient for normal use, if the kettle accidentally tipes over, the liquid inside will flow out rapidly from the spout, posing safety hazards such as burns and staining of tabletops or floors, especially when filled with hot water. Utility Model Content

[0004] The purpose of this invention is to provide a kettle spout valve that is simple in structure, easy to operate, and can effectively prevent the kettle from tipping over without affecting the normal pouring function.

[0005] A kettle spout valve includes: a mounting sleeve, which is cylindrical and extends vertically; a locking structure is provided on the lower side of the mounting sleeve; a valve cover body, rotatably connected to the outer edge of the upper opening of the mounting sleeve, including a closing end near the upper opening and a retaining end away from the upper opening; a reset assembly, disposed at the rotatable connection position between the valve cover body and the mounting sleeve; a positioning structure, disposed on the outer periphery of the mounting sleeve, adapted to the retaining end for positioning; in a first working state, the positioning structure retains the retaining end, the closing end is close to the upper opening, and the reset assembly has a reset potential energy; in a second working state, the positioning and retaining structure releases the retaining restriction on the valve cover body, and under the reset force of the reset assembly, the closing end is positioned away from the upper opening of the mounting sleeve.

[0006] Furthermore, the mounting sleeve extends in an arc shape to form a cylindrical shape; an angle is formed between the horizontal extension position of the upper opening and the horizontal extension position of the lower opening of the mounting sleeve.

[0007] Furthermore, the lower section of the outer periphery of the mounting sleeve has a strip-shaped opening that connects to the lower opening, and the extension direction of the strip-shaped opening is the same as the extension direction of the mounting sleeve; the locking structure includes locking plates extending outward on both sides of the strip-shaped opening, and locking bolts are connected between the two locking plates.

[0008] Furthermore, an extended opening is provided on the middle section of the outer periphery of the mounting sleeve corresponding to the strip-shaped opening, and the width of the extended opening is greater than the width of the strip-shaped opening.

[0009] Furthermore, positioning plates are provided on both sides of the upper outer periphery of the mounting sleeve, and a rotating shaft is connected between the two positioning plates. The valve cover body passes through the rotating shaft to achieve a rotatable connection relative to the mounting sleeve. The reset assembly includes a torsion spring passing through the rotating shaft, and the torsion spring is elastically connected between the valve cover body and the mounting sleeve.

[0010] Furthermore, the positioning structure includes a pressing positioning block disposed in the middle section of the outer periphery of the mounting sleeve. The pressing positioning block is T-shaped and includes a deformation section connected to the mounting sleeve, a retaining section disposed near the valve cover body, and a pressing section disposed away from the valve cover body. In the first working state, the lower side of the retaining end abuts against the retaining section and is limited, and the torsion spring has elastic restoring potential energy. In the second working state, pressing the pressing section causes the deformation section to deform, the retaining section retracts and releases the limitation on the retaining end, the torsion spring releases elastic potential energy and has elastic restoring force, which in turn causes the valve cover body to rotate around the rotating axis, the closing end moves away from the upper opening of the mounting sleeve, and the retaining end moves towards the mounting sleeve.

[0011] Furthermore, relative to the rotating shaft, the size of the closing end of the valve cover is larger than the size of the holding end; the lower side of the closing end of the valve cover is flat, and a sealing block is formed by protruding from the lower part of the closing end of the valve cover.

[0012] A kettle structure includes a kettle body and a spout section extending from one side of the kettle body; the spout section has a water outlet connected to a kettle spout valve as described above; a locking structure is locked to the spout section; when in the first working state, a sealing block is inserted into the water outlet and forms an interference fit.

[0013] The beneficial effects of this utility model are as follows:

[0014] The kettle spout valve, through the application of a reset component, allows the valve cover to move towards the upper opening of the mounting sleeve in the normal state (first working state). This adapts to the spout section of the kettle structure when the kettle spout valve is installed, forming a seal on the water outlet. This effectively solves the safety problem of liquid spillage when the kettle is accidentally tipped over, and is especially suitable for scenarios containing hot water, thus improving the safety of using the kettle.

[0024] To make the technical solution, purpose and advantages of this utility model clearer, the following explanation is given in conjunction with the accompanying drawings and embodiments.

[0025] like Figures 1 to 3 As shown, this utility model discloses a kettle spout valve, which is used to be installed at the spout section 5 position in the kettle structure and applied to the water outlet 51. Its structure includes:

[0026] Mounting sleeve 1: It is cylindrical in shape with its top and bottom open, and is used to fit and fix it onto the spout section 5. The lower side of the mounting sleeve 1 is provided with a locking structure 11 for locking and engaging with the spout section 5.

[0027] Valve cover body 2: Rotatably connected to the outer edge of the upper opening 101 of the mounting sleeve 1. The valve cover body 2 includes a closing end 21 near the upper opening 101 of the mounting sleeve 1 and a retaining end 22 away from the upper opening 101.

[0028] Reset component 3: Located at the rotatable connection position between the valve cover body 2 and the mounting sleeve 1, it is used to provide a reset force to the valve cover body 2 that tends to open.

[0029] Positioning structure 4: It is set on the outer periphery of the mounting sleeve 1 and is used to cooperate with the retaining end 22 of the valve cover body 2 to achieve retaining and positioning of the valve cover body 2 in the closed state.

[0030] The kettle spout valve has two operating states in its application:

[0031] First working state (closed state): The positioning structure 4 is engaged with the holding end 22 of the valve cover body 2, so that the closing end 21 of the valve cover body 2 abuts against and seals the upper opening 101 of the mounting sleeve 1. At this time, the reset assembly 3 is under pressure and stores reset potential energy.

[0032] In practical applications, the valve cover 2's closed end 21 is adapted to the spout section 5 structure for use. In the closed state, the valve cover 2 is set to seal the water outlet 51.

[0033] Second working state (open state): By operating the positioning structure 4 to release the restriction on the valve cover body 2 holding end 22, under the action of the reset potential energy stored in the reset component 3, the valve cover body 2 rotates, and its closed end 21 moves away from the upper opening 101 of the mounting sleeve 1, thereby opening the water outlet 51, so that the water source in the kettle can flow out smoothly from the water outlet 51 through the upper opening 101 position.

[0034] The specific structural design scheme has the following structural details:

[0035] The mounting sleeve 1 serves as the main support structure, and is a hollow cylindrical shape that runs from top to bottom. Its internal cavity is designed to fit the outer circumference of the spout section 5. The mounting sleeve 1 is designed as a curved cylinder with a certain curvature, so that the horizontal extension surface of its upper opening 101 and the horizontal extension surface of its lower opening 102 form an angle of approximately 5 to 15 degrees. This angle design allows the lower opening 102 of the installed spout valve to fit the middle curved section of the spout section 5, while the upper opening 101 naturally faces diagonally forward or to the side forward, fitting the tilt angle of the spout at the water outlet 51 of the spout section 5, while also leaving space for the flipping movement of the valve cover 2.

[0036] To achieve a secure connection with the spout, an axially extending strip-shaped opening 111 is formed in the lower section of the outer periphery of the mounting sleeve 1. The strip-shaped opening 111 penetrates the pipe wall, dividing the lower section of the mounting sleeve 1 into two elastic halves. On both sides of the strip-shaped opening 111, locking plates 112 extend outwards integrally to form locking plates 112. Corresponding through holes and screw holes are formed on the locking plates 112 on both sides, allowing bolts 113 to pass through and be screwed in. By tightening the bolts 113 with a tool, the locking plates 112 on both sides can be brought together, thereby forcing the inner diameter of the lower section of the mounting sleeve 1 to decrease, thus tightly clamping it to the outer wall of the spout section 5. Conversely, loosening the bolts 113 allows the lower section of the mounting sleeve 1 to return to its original shape, facilitating disassembly or repositioning. This design allows the kettle spout valve to be adapted to the spout sections 5 of different kettles within a certain diameter range. To facilitate the deformation of the locking plate 112, an extended opening 114, significantly wider than the strip opening 111, is provided in the middle section of the outer periphery of the mounting sleeve 1, directly above the strip opening 111. This extended opening 114 provides additional elastic deformation space to meet the locking application of the kettle spout valve on the external spout section 5.

[0037] The valve cover body 2 is the core component that performs the opening and closing functions.

[0038] The valve cover body 2 is generally elongated and is mounted on the upper side of the mounting sleeve 1 via a rotatable connection. Specifically, on the upper section of the outer periphery of the mounting sleeve 1, near the rear of the upper opening 101, a pair of positioning plates 12 extend upwards to form a pair of positioning plates 12, with a rotating shaft 13 passing between the two positioning plates 12. The middle and rear part of the valve cover body 2 (i.e., near the holding end 22) is provided with a shaft hole, allowing it to be fitted onto the rotating shaft 13 and rotate smoothly around the rotating shaft 13.

[0039] With the rotating shaft 13 as the boundary, the valve cover body 2 can be divided into a front closing end 21 and a rear retaining end 22. The closing end 21 is used to seal the water outlet. Relative to the rotating shaft 13, a section of the closing end 21 of the valve cover body 2 is larger than a section of its retaining end 22; the lower side of the closing end 21 of the valve cover body 2 is flat. On the lower surface of the flat closing end 21, a sealing block 23 made of soft material is fixed. When the valve cover body 2 is in the closed state, the sealing block 23 is inserted into the water outlet 51 of the assembled spout section 5. The outer diameter of the sealing block 23 is slightly larger than the inner diameter of the water outlet 51, forming an interference fit, thereby achieving a reliable liquid seal and preventing water leakage.

[0040] The reset assembly 3 is used to provide the driving force for the valve cover body 2 to open automatically.

[0041] In this embodiment, a torsion spring 31 sleeved on the rotating shaft 13 is used as the reset component 3. The middle part of the torsion spring 31 surrounds the rotating shaft 13, with one end (lever arm one) abutting or hooking against the mounting sleeve 1, and the other end (lever arm two) abutting or hooking against a specific part of the valve cover body 2 (such as the lower side of the valve cover body 2 near the rotating shaft 13). The torsion spring 31 is pre-tightened, and its natural state tends to drive the valve cover body 2 to rotate in the opening direction (i.e., the closed end 21 is lifted upward). When the valve cover body 2 is pressed to the closed state, the torsion spring 31 is further torsion, storing elastic potential energy.

[0042] The positioning structure 4 is used to stably lock the valve cover body 2 in the closed state.

[0043] In this embodiment, the positioning structure 4 is an integrally molded pressing positioning block 41, which is connected to the middle section of the outer wall of the mounting sleeve 1 by injection molding. The pressing positioning block 41 is generally T-shaped and includes a deformation section 411 connected to the mounting sleeve 1, a retaining section 412 located near the valve cover body 2, and a pressing section 413 located away from the valve cover body 2.

[0044] Deformation section 411: This is the root part that connects to the wall of the mounting sleeve 1. It is relatively thin and has good elastic bending performance.

[0045] Clamping section 412: Located at the upper end of the positioning block, near the clamping end 22 of the valve cover body 2. It has an upward protrusion or flat abutment surface on its upper part.

[0046] Pressing section 413: Located at the lower end of the positioning block, on the side away from the valve cover body 2. Its outer surface can be designed with a spherical end for easy finger pressing.

[0047] In the first working state (closed), the lower side of the retaining end 22 of the valve cover 2 is pressed against the abutting surface of the retaining section 412. At this time, the elastic force of the torsion spring 31 attempts to open the valve cover 2, but the force is transmitted through the valve cover 2 to the retaining section 412 and is resisted by the structural strength of the pressing positioning block 41, thereby keeping the entire system stably closed.

[0048] In the second working state (open), pressing the pressing section 413 causes the deformation section 411 to deform, the retaining section 412 retracts and releases the restriction on the retaining end 22, the torsion spring 31 releases elastic potential energy and has an elastic restoring force, which in turn causes the valve cover body 2 to rotate around the rotating shaft 13, so that the closing end 21 moves away from the upper opening 101 of the mounting sleeve 1 and the retaining end 22 moves towards the mounting sleeve 1, thereby realizing the flipping opening of the closing end 21 relative to the upper opening 101.

[0049] The working process of a kettle that uses a spout valve is as follows:

[0050] After the kettle spout valve is installed on the spout section 5, the valve cover 2 is in its first working state, and the sealing block 23 tightly plugs the water outlet 51. If the kettle is accidentally tilted in any direction, the liquid inside the kettle cannot flow out from the spout section 5 because the water outlet has been physically sealed, thus achieving the anti-tipping function.

[0051] When water needs to be poured, the user holds the kettle body with one hand and presses the pressing section 413 of the positioning structure 4 with the other. The pressing force causes the deformation section 411 to elastically bend and deform, driving the upper locking section 412 to move backward (away from the valve cover body 2). Once the abutting surface of the locking section 412 disengages from the locking end 22 of the valve cover body 2, the locking of the valve cover body 2 is released. At this time, the torsion spring 31, which has been compressed for a long time, instantly releases its stored elastic potential energy, generating a torsional force that drives the valve cover body 2 to quickly flip upward around the rotation axis 13. The closed end 21 of the valve cover body 2 quickly lifts up, and the sealing block 23 is pulled out from the water outlet 51, making the water outlet 51 completely open, allowing the water in the kettle to flow out smoothly. Under the action of the spring force, the valve cover body 2 will flip to a limit position and maintain a stable open state for continuous pouring.

[0052] After the water is poured out, the user simply needs to use their hand to flip the raised valve cover 2 (pressing down its closed end 21) downwards and press it back down until its locking end 22 passes over the locking section 412 again and is pressed into place, producing a slight "click" sound. This indicates that the valve cover 2 has been locked back by the locking section 412 and returned to the closed state, ready for the next anti-tipping protection. During this process, the torsion spring 31 is compressed and stored energy again.

[0053] The above description is only a preferred embodiment of the present utility model. For those skilled in the art, modifications can still be made to the embodiments without departing from the implementation principle of the present utility model, and the corresponding modifications should also be considered within the protection scope of the present utility model.
