Handheld gas-powered pocket heater for quick hand warming and warming of the inside of your pocket

Abstract

(Main claim): Portable, handheld, gas-powered heater (100) comprising a double-layer flame chamber (120) within a heat-resistant housing (110), a perforated ceramic outlet (130) for controlled heat release, air mixing openings (140) for mixing ambient air with heated air, a refillable gas tank (150) arranged outside the heated chamber, and an ignition mechanism (160).

Description

Technical area:

[0001] The present invention relates to portable heaters, particularly to a gas-powered pocket heater that quickly heats the internal temperature of a pocket and warms cold hands in a very short time. Background of the invention:

[0002] In cold weather, people often put their hands in their pockets to warm them up. However, this process can be time-consuming before noticeable warmth develops. Current solutions such as chemical heat packs, rechargeable electrical devices, or older fuel-fired heaters have limitations: They are slow, expensive to operate, or pose safety risks. This invention offers a solution by providing a portable, efficient, and safe gas-powered pocket heater that delivers instant warmth. The compact, ergonomic design ensures ease of use without compromising the user's mobility. Additionally, the device could reduce the dependence on indoor heating systems for rapid warm-up processes, thus contributing to better energy efficiency. Description of the invention:

[0003] The handheld gas-powered pocket heater is compact and ergonomically designed, roughly the size of two standard lighters. This handy design allows for easy use in jacket or coat pockets while ensuring safe and efficient heat distribution. Key features: 1. Compact, ergonomic design: ◯ Fits in most jacket or coat pockets without discomfort or bulk. ◯ Practical and portable, ideal for use on the go. 2. Double sealed flame chamber: ◯ The flame is safely enclosed in a double-layer chamber to ensure safe use. 3. Perforated ceramic ventilation system: ◯ Enables controlled and even heat distribution. 4. Air mixing system: ◯ Mixes heated air with ambient air for optimal temperature and safe use. 5. Universal refillable gas tank: ◯ Powered by a small refillable or replaceable gas tank placed outside the heating zone to prevent overheating. 6. Durable, heat-resistant housing: ◯ Made of lightweight and robust material such as high-strength plastic or metal. ◯ Ergonomically designed for safe handling without risk of burns. 7. Ignition mechanism: ◯ A simple and reliable spark ignition mechanism, similar to that of a lighter. 8. Optional mechanical timer: ◯ Limiting the operating time for additional safety and user-friendliness. 9. Security features: ◯ Automatic shut-off valve to interrupt the gas flow when the device is not in use. ◯ Heat shield to protect against burns. ◯ Optional temperature monitoring system to prevent overheating. 10. Temperature output: • Designed to deliver controlled heat between 35°C and 45°C, effectively warming hands without damaging tissue or causing discomfort. Fig. 1 shows a perspective external view of the device (100) with housing (110), ceramic outlet (130), ignition mechanism (160), automatic shut-off valve (170) and the heat shield (180) arranged at the outlet. Fig. 2 shows a partially cutaway perspective of the housing (110) with the arrangement of the refillable gas tank (150) relative to the ceramic outlet (130) and the air mixing openings (140). Fig. Figure 3 shows an embodiment with an automatic timer (190) on the front; also shown are the ignition mechanism (160), the automatic shut-off valve (170) and the heat shield (180) arranged at the outlet; the double-layer flame chamber (120) is arranged in the housing. Fig. Figure 4 shows a perspective view focusing on the double-layer flame chamber (120) and the ceramic outlet (130), as well as the air mixing ports (140) and the ignition mechanism (160).
