Description

Technical Field

[0001] This utility model belongs to the field of daily necessities technology, specifically relating to a multifunctional hand warmer. Background Technology

[0002] With the development of science and technology and the improvement of people's living standards, hand warmers, as a portable heating device, have been widely welcomed due to their convenience and practicality. However, existing hand warmer products still have some obvious defects, which limit their further development and popularization.

[0003] First, most existing hand warmers are disposable or reusable products with a fixed temperature, lacking temperature regulation function. This means that users cannot adjust the temperature according to their personal needs or changes in the environment, which affects the comfort and effectiveness of use. In cold weather, users may want the hand warmer to provide a higher temperature to quickly get warm; while in a slightly warmer environment, an excessively high temperature may cause discomfort.

[0004] Secondly, in medical settings, such as during blood draws for physical examinations, traditional hand warmers are less effective. Because they cannot adjust the temperature, they cannot precisely control the temperature of the heat applied to the blood vessels. Too low a temperature may not effectively promote vasodilation, making blood draws difficult, while too high a temperature may cause burns or other safety hazards to the patient.

[0005] To address the above problems, this utility model provides a multifunctional hand warmer. Utility Model Content

[0006] The purpose of this invention is to provide a multifunctional hand warmer that can adjust the temperature of the hand warmer.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] Example 1:

[0024] like Figure 1-2 As shown, a multifunctional hand warmer includes a hand warmer body 1. The top of the hand warmer body 1 has a slot 11. When a user is receiving intravenous infusion, the infusion tube can be secured in the slot 11, thereby warming the infusion tube and preventing pain caused by excessively low temperatures. The hand warmer body 1 has a heating chamber 7 inside. When placed in a standard blood-drawing pad, the hand warmer body 1 can generate heat during blood draws, reducing the cold pain at the blood draw site. Furthermore, the blood draw pad containing the hand warmer body 1 can be used for heat therapy at the blood draw site. The heating chamber 7 of the hand warmer body 1 contains iron powder and salt, and its function is as follows:

[0025] Iron powder reacts with oxygen in the air to produce ferric oxide, a process that releases a large amount of heat.

[0026] Salt as a catalyst: Salt acts as a catalyst in the reaction, helping to accelerate the oxidation of iron;

[0027] In addition to the iron powder and salt mentioned above, the heating chamber 7 of the hand warmer body 1 also contains water and a fixed vermiculite block 8, wherein:

[0028] The role of water is that the oxidation reaction of iron powder is an exothermic reaction, which requires water molecules to promote the reaction. Water acts as a regulator, and by controlling humidity, it can ensure a stable reaction rate and prevent the temperature from becoming too high or too low.

[0029] Vermiculite has excellent water absorption and retention properties. In hand warmers, vermiculite can absorb the moisture produced by the reaction, preventing excessive moisture evaporation from affecting the reaction rate. At the same time, vermiculite can also slowly release moisture during the reaction process, maintaining humidity balance, thereby regulating the reaction rate and temperature.

[0030] The top of the hand warmer body 1 is equipped with a water storage tank 2, which contains water. At least one water leakage hole 4 is provided at the bottom of the water storage tank 2. The water flows into the interior of the hand warmer body 1 through the water leakage hole 4 to achieve the heating effect. The interior of the water storage tank 2 is also equipped with a blocking structure to block the water leakage hole 4. The water leakage hole 4 is connected to the heating chamber 7.

[0031] See attached document Figure 2The blocking structure includes a rotating column 3 rotatably connected inside the water storage tank 2. A ring of anti-slip grooves is provided on the outer edge of the top of the rotating column 3 to prevent the user's hand from slipping when rotating the rotating column 3. A water-blocking plate 5 corresponding to the leakage hole 4 is fixed on the outside of the rotating column 3, and the water-blocking plate 5 is used to block the leakage hole 4. The material of the water-blocking plate 5 can be any blocking material, such as rubber, which can effectively block the leakage hole 4. A groove is provided inside the bottom end of the rotating column 3, and a torsion spring 6 is installed in the groove. One end of the torsion spring 6 is connected to the water storage tank 2 and the rotating column 3 respectively.

[0032] Water is added to the water storage tank 2 to the hand warmer. When the user feels that the heat is low, the rotating column 3 can be rotated, which will cause the water blocking plate 5 to rotate and the water blocking plate 5 will not block the water leakage hole 4. At this time, the water can be transported from the water leakage hole 4 to the heating chamber 7. The user can shake the water inside the hand warmer body 1 to mix it evenly. The entry of water can accelerate the heat release reaction, thereby achieving the purpose of rapid heating.

[0033] After a little water is added, the user releases the rotating column 3. The torsion spring 6 is set to automatically reset, so that the water blocking plate 5 blocks the leakage hole 4 again.

[0034] The water storage tank 2 contains a small amount of water, thus preventing the hand warmer body 1 from reacting violently and causing burns or even scalding.

[0035] Example 2:

[0036] This embodiment is a further improvement on embodiment 1, as follows:

[0037] See attached document Figure 3 and attached Figure 4 Multiple fixed vermiculite blocks 8 are evenly assembled inside the heating chamber 7. Sliding vermiculite blocks 9 are slidably connected inside the fixed vermiculite blocks 8. A connecting rod 10 is connected to the end of the sliding vermiculite block 9 away from the fixed vermiculite block 8. The end of the connecting rod 10 extends to the outside of the hand warmer body 1. A sealing partition 12 is provided on the inner wall of the fixed vermiculite block 8. A sealing baffle 13 is provided at the end of the sliding vermiculite block 9 away from the fixed vermiculite block 8. With this arrangement, when the sliding vermiculite block 9 is entirely inside the fixed vermiculite block 8, the fixed vermiculite block 8 is prevented from reacting with the external water by the blocking of the sealing partition 12 and the sealing baffle 13. Only when the user moves the sliding vermiculite block 9 out of the fixed vermiculite block 8 can the sliding vermiculite block 9 react with the water.

[0038] When the user notices that the hand warmer is too hot, they can press the outside of the connecting rod 10 to move the connecting rod 10 and drive the sliding vermiculite block 9 to move towards the outside of the fixed vermiculite block 8. This allows the sliding vermiculite block 9 to react with the water in the heating chamber 7, causing the extra sliding vermiculite block 9 to absorb the water, thereby reducing the excessive reaction of too much water and lowering the temperature of the hand warmer.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
