The origin of the cooker

Gas stoves have a fascinating history that dates back to the early 19th century. The earliest known gas stove was developed by a Frenchman named Philip Ruben, who obtained a patent for a gas-fired and heating dual-use device on September 21, 1799. Just a year later, he installed this equipment in a Parisian restaurant. However, the early gas stove had a major drawback — it emitted an unpleasant odor, which made it unpopular at first. Despite this setback, Ruben remained enthusiastic and continued improving his design. Tragically, his work was cut short when he was killed in a street accident in Paris on the day of Napoleon's coronation in 1804.

It wasn't until 1826 that the first gas stove designed specifically for kitchen use appeared. James Schaff, the deputy manager of the Northampton Gas Company in the UK, created a vertical stove with a hook hanging from the ceiling to hold meat and a circular fire pit below. This early model didn’t include a pan or cooking surface, but it marked a significant step forward in home cooking technology.

The first commercial adoption of a gas stove came in 1834 when a bus inn in Leamington, France, used one to prepare a meal for 100 people. Not only was the food delicious, but it also lacked the typical gas smell, making it an ideal choice. By 1836, a factory in Northampton, England, began mass-producing gas stoves, signaling the start of a new era in domestic cooking.

In 1852, gas stoves began to combine both the burner and the cooking surface, making them more practical and efficient. Then, in 1915, the introduction of thermostatic control added another level of convenience and precision to gas stoves.

A major breakthrough in gas technology came in 1855 when the German chemist Robert Bunsen invented the "Bunsen burner," a device that mixed oxygen with flammable gas to produce a high-temperature flame. Just a year after its invention, the British company Hoddington Anton Smith introduced the world’s first gas-powered domestic heating system. As gas stoves became more popular and gas supply networks expanded, modern gas cookers gradually evolved into the efficient and widely-used appliances we know today.

LED Headlamp

‌‌The headlamp is a kind of lighting tool worn on the head, mainly used to free the hands of lighting. ‌ The design of the headlights allows users to carry out various activities, such as night walking, camping, exploring, etc., without the need for hand-held lighting, thereby freeing up both hands for other operations. Headlamp is usually composed of headlamp body, charger, rechargeable battery, ‌ power socket and ‌ cable, etc., to provide stable lighting effect. The use of headlights is widely used, not only for outdoor activities, but also for some indoor activities, such as night reading, repair and so on. ‌
When choosing a headlamp, there are several key factors to consider: ‌ brightness, ‌ irradiation distance, ‌ battery life, ‌ waterproof and dustproof ability. The ideal headlamp should have enough brightness to cope with different lighting needs, good irradiation distance to ensure safety, long battery life to meet the needs of long-term use, and a certain waterproof and dustproof ability to adapt to various environments. In addition, the type of headlamp battery is also an important consideration, you can choose a rechargeable or replaceable battery headlamp, according to the use of habits and needs to choose.
The brightness of the headlamp is usually measured in lumen, and the higher the lumen value, the higher the brightness of the lamp. Waterproof and dustproof rating is also an important indicator of headlamp performance, in general, IPX6 or above waterproof rating can meet the needs of most outdoor activities. When choosing a headlamp, you should also consider its light source type, such as ‌LED, ‌ halogen or ‌ xenon, etc. Each light source type has its own unique advantages and disadvantages, and is suitable for different scenes and needs.
