Description

Technical Field

[0001] This utility model relates to the technical field of kettle wire protection, specifically a high-safety kettle wire protection structure. Background Technology

[0002] A kettle is a utensil used to heat water. It is convenient to use, heats water quickly, and usually has an automatic power-off function, making it relatively safe. Existing kettles typically consist of a lower base and an upper kettle body, which can be separated from each other. The base is connected to a wire, which is the power cord, and is connected to an external power source. After the kettle body is placed on the base, the water inside the kettle is heated by the external power supply. It is now widely used.

[0003] When the connecting wire on the base is too long, it is very inconvenient to use. If it is too short, it cannot be connected to the socket, affecting its normal use. Moreover, the wire is directly exposed to the outside, and the surface of the wire is prone to wear, which shortens the service life of the wire. Therefore, some kettles make the wire extension length adjustable. They use a spring-driven mechanism to rotate the winding reel through a gear transmission mechanism, thereby realizing the automatic winding of the wire to adjust the extension length of the wire, thus making it suitable for actual conditions.

[0004] However, the existing structure usually involves directly winding the wires onto the reel. When not much extension length is needed, most of the wires need to be wound together very tightly, which results in poor heat dissipation and a risk of overheating. To address this, we have provided a high-safety kettle wire protection structure to solve the above problems. Utility Model Content

[0005] 1) Technical problems to be solved

[0006] This utility model proposes a high-safety-performance kettle cord protection structure. Through the cooperation of components such as a sliding rod and a limiting mechanism, when the length of the cord outside the storage box is short, the part of the cord inside the storage box is S-shaped. The sliding rod limits its shape to maintain this shape, thus preventing the part of the cord inside the storage box from getting tangled. The different positions of the cord also have a certain space to prevent them from contacting each other, thereby increasing the air contact area and improving the heat dissipation effect.

[0007] (ii) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a high-safety kettle cord protection structure, comprising a cord connected to the kettle base, a storage box being provided outside the cord, and one end of the cord near the kettle base penetrating through and being fixedly connected to the top of the storage box; the outer surface of the cord being slidably connected to one side of the storage box; four rectangular slots being provided at the bottom of the storage box, a sliding rod being slidably connected to the inner wall of each rectangular slot, a rotating cylinder being rotatably connected to the outer surface of the sliding rod, and the outer surface of the rotating cylinder contacting the cord; a support plate being fixedly installed on the side of the storage box, and an adjustment mechanism for adjusting the position of the sliding rod being provided at the bottom of the storage box.

[0009] Furthermore, a wind mechanism for blowing air into the storage box is provided on one side of the storage box, and an air vent is provided on the side of the storage box away from the wind mechanism.

[0010] Furthermore, the wind power mechanism includes a housing, the outer surface of which is fixedly connected to the storage box, and two fans are fixedly installed inside the housing.

[0011] Furthermore, a heat-insulating pad is bonded to the upper surface of the storage box, and the outer surface of the wire passes through the heat-insulating pad.

[0012] Furthermore, the adjustment mechanism includes a threaded rod, the end of which is rotatably connected to a support plate, and two sliding plates are threadedly connected to the outer surface of the threaded rod. The upper surface of the sliding plates is fixedly connected to the sliding rod, and a knob is fixedly connected to the end of the threaded rod.

[0013] Furthermore, a limiting rod is slidably connected to the inner wall of the sliding plate, and the two ends of the limiting rod are respectively fixedly connected to two support plates.

[0014] (iii) Beneficial effects:

[0015] Compared with existing technologies, this high-safety kettle wire protection structure has the following advantages:

[0016] 1. This high-safety kettle cord protection structure, through the cooperation of components such as sliding rods and limiting mechanisms, ensures that when the cord's length outside the storage box is short, the portion of the cord inside the storage box is S-shaped. The sliding rod limits this shape, preventing the cord from tangling and ensuring that different parts of the cord have sufficient space to avoid contact, thereby increasing the air contact area and improving heat dissipation.

[0017] Second, the high-safety-performance kettle cord protection structure incorporates components such as a fan mechanism. The fan mechanism allows outside air to enter the storage box, thereby carrying away the heat from the cord. Some air flows out from the rectangular slot, while the rest flows out from the vent, thus achieving air circulation and further enhancing the cooling effect. Attached Figure Description

[0025] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The fan 802 in this utility model is a common electrical device in the prior art, and this application will not elaborate on its model or internal structure.

[0027] like Figure 1-5As shown, this utility model provides a technical solution: a high-safety kettle cord protection structure, including a cord 1 connected to the kettle base, a storage box 2 disposed outside the cord 1, and the end of the cord 1 near the kettle base passing through and fixedly connected to the top of the storage box 2, the outer surface of the cord 1 being slidably connected to one side of the storage box 2; four rectangular slots 3 are provided at the bottom of the storage box 2, and a sliding rod 4 is slidably connected to the inner wall of each rectangular slot 3, the outer surface of the sliding rod 4 being rotatably connected to a rotating cylinder 5, the outer surface of the rotating cylinder 5 being in contact with the cord 1; a support plate 6 is fixedly installed on the side of the storage box 2, and a function for adjusting the cord is provided at the bottom of the storage box 2. The sliding rod 4 has an adjustment mechanism 7. The interior of the storage box 2 is hollow, and the kettle base is installed on top of it, which can support the kettle base. The part of the wire 1 inside the storage box 2 is S-shaped and is limited by the sliding rod 4 to maintain its shape, so that the part of the wire 1 inside the storage box 2 will not be tangled together, and there is a certain space between different positions of the wire 1 so that they will not touch, thereby increasing its air contact area and improving the heat dissipation effect. The width of the rectangular groove 3 is the same as the width of the sliding rod 4, so that the sliding rod 4 can slide inside the rectangular groove 3. There are two support plates 6 to support the whole.

[0028] A fan mechanism 8 is provided on one side of the storage box 2 to blow air into the storage box 2. An air outlet 9 is provided on the side of the storage box 2 away from the fan mechanism 8. The fan mechanism 8 can allow outside air to enter the storage box 2, thereby removing the heat from the wire 1. Part of the air flows out from the rectangular groove 3, and the other part flows out from the air outlet 9, thereby realizing air circulation and further increasing the cooling effect.

[0029] The wind power mechanism 8 includes a housing 801, the outer surface of which is fixedly connected to the storage box 2. Two fans 802 are fixedly installed inside the housing 801. The fans 802 can blow outside air into the storage box 2. The housing 801 is used to protect it. A filter screen is also included on one side of the housing 801 to prevent external solid waste from entering.

[0030] The upper surface of the storage box 2 is bonded with a heat insulation pad 10, and the outer surface of the wire 1 passes through the heat insulation pad 10. The kettle base is specifically installed on the upper surface of the heat insulation pad 10. The heat insulation pad 10 is used to isolate the heat on the kettle base from being transferred downwards, thus avoiding heat interaction.

[0031] The adjustment mechanism 7 includes a threaded rod 701, the end of which is rotatably connected to the support plate 6. Two sliding plates 702 are threadedly connected to the outer surface of the threaded rod 701. The upper surface of the sliding plates 702 is fixedly connected to the sliding rod 4. A knob 704 is fixedly connected to the end of the threaded rod 701. The threaded rod 701 has a bidirectional thread, with the threads on both sides having opposite helical directions, with the middle as the boundary. When the threaded rod 701 rotates in the forward direction, it can drive the two sliding rods 4 to move away from each other. When the threaded rod 701 rotates in the reverse direction, it can drive the two sliding rods 4 to move closer to each other, thereby causing the sliding rods 4 to make corresponding movements to adjust the distance between the wire 1 inside the storage box 2 and the middle of the storage box 2. This allows the wire 1 to extend outward or retract inward, thereby adjusting the length of the wire 1 outside the storage box 2. The knob 704 is used for easy turning.

[0032] The inner wall of the sliding plate 702 is slidably connected to a limiting rod 703. The two ends of the limiting rod 703 are fixedly connected to two support plates 6 respectively. There are two limiting rods 703, which are used to increase the stability of the two sliding plates 702 and prevent them from shifting or tilting.

[0033] Working principle: When it is necessary to adjust the extension length of the wire 1 during use, the position of the sliding rod 4 is adjusted by the adjustment mechanism 7, so that the multiple sliding rods 4 move closer to or further away from the middle position of the storage box 2, thereby allowing the wire 1 to extend outward or retract inward, thus adjusting the length of the wire 1 outside the storage box 2 for easy use. When the wire 1 is pulled out, the rotating cylinder 5 also reduces the friction between the wire 1 and the sliding rod 4, so that the position of the wire 1 and the sliding rod 4 changes.

[0034] When the length of the wire 1 outside the storage box 2 is short, the part of the wire 1 inside the storage box 2 is S-shaped and is limited by the sliding rod 4 to maintain its shape. This prevents the part of the wire 1 inside the storage box 2 from getting tangled, and ensures that different positions of the wire 1 have a certain space so that they do not touch, thereby increasing its air contact area and improving heat dissipation.

[0035] In the description of this utility model, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inner", "outer", "back", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
