Description

Technical Field

[0001] This utility model relates to the field of hand warmer technology, and in particular to a retractable lamp hand warmer. Background Technology

[0002] Hand warmers can be broadly categorized into three types: One type heats up by heating water, commonly known as a hot water bottle. Unlike traditional hot water bottles, electric hot water bottles eliminate the hassle of adding water; simply plug them in and wait about 10 minutes for them to heat up. Essentially, they boil the water, resulting in a generally high temperature. Another type heats up through a chemical reaction; most hand warmers on the market fall into this category. Heat is generated through the contact of internal chemicals, reaching temperatures around 40°C. A third type uses a lithium battery with an internal heating element, charging and discharging via a USB interface, similar to a hand-warming mouse pad. Because lithium batteries can be charged and discharged, they can also be used as a power bank. These are small, portable, and can reach temperatures of around 50°C.

[0003] Existing lithium battery-powered hand warmers typically offer both hand warming and lighting functions, but their lighting area is small and the lighting effect is poor. Therefore, a new technological solution is needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a retractable hand warmer to solve the problem of poor lighting effect in existing hand warmers.

[0005] This utility model provides a retractable hand warmer, including a housing, a battery disposed within the housing, and a heating element disposed at the lower end of the housing and electrically connected to the battery. It also includes a retractable lamp assembly disposed at the upper end of the housing and electrically connected to the battery. The retractable lamp assembly includes a lamp plate, an LED bead disposed at the upper end of the lamp plate, and a retractable lampshade disposed at the upper end of the LED bead. The housing has a receiving groove at a position corresponding to the retractable lampshade, and the retractable lampshade is received in the receiving groove.

[0006] The aforementioned retractable hand warmer, by incorporating a retractable lamp assembly, allows the light emitted by the lamp beads to be diffused over a large area when large-area lighting is needed, thus improving the lighting effect.

[0007] Furthermore, a temperature control button is provided on one side of the housing.

[0008] Furthermore, a lighting control button is provided on one side of the housing.

[0009] Furthermore, a USB interface is provided on one side of the housing.

[0010] Furthermore, a power indicator light is provided on one side of the housing.

[0011] Furthermore, a lanyard hole is provided on one side of the housing.

[0012] Furthermore, the side of the housing is provided with anti-slip grooves. Attached Figure Description
