Toaster is a commonly used kitchen appliance, mainly used to toast slices of bread. The toaster usually includes a multi-function oven, an insulated stove top, and a special lifting device. The more advanced ones also include a detachable bread crumb chassis. An air fryer is a machine that can use air to "fry". It mainly uses air to replace the hot oil in the original frying pan to make the food cooked. At the same time, the hot air also blows away the moisture on the surface of the food, so that the food is almost fried.

Nowadays, air wrenches are mainly used in various assembly operations and several major parts, such as air motors, whacking devices or reduction devices. Due to its high speed, high efficiency and low temperature rise, it has become an indispensable tool for the assembly industry. There are different shapes, designs and styles of air wrenches in the market, so it is better to know its classification before buying.

Flower pot is a kind of vessel for planting flowers, which is widely used in landscaping and plant landscape engineering. They are in various forms and sizes. We can choose the suitable flower pots according to the characteristics and needs of the flowers. Plastic flowerpot is a kind of flowerpot made of plastic. Compared with traditional porcelain flowerpot, watering times are less. The price is relatively cheap and durable.

The most obvious difference between a laser engraving machine and a CNC engraving machine is that the laser engraving machine performs engraving by laser melting or burning. CNC engraving machine uses digital technology to control the cutting tool, bit or laser head, ultrasonic head for engraving. The laser engraving machine can be a CNC engraving machine, and the CNC engraving machine can also be equipped with a laser head for laser engraving. Therefore, the two have a cross and intersection relationship. Although both the laser engraving machine and the CNC engraving machine adopt a numerical control system, they have different working principles and different mechanical structures. In comparison, the CNC engraving machine has a simpler structure. Through the control of computer numerical control system, the engraving machine can automatically select the appropriate engraving tool to engrave on the X, Y, and Z axes of the machine tool. The biggest difference in structure between laser engraving machine and CNC engraving machine is that the cutter of laser engraving machine is a complete set of optical components, while the cutter of CNC engraving machine is a variety of entity engraving cutters.

Laser distance measurement and radio detection radars follow the same operating principle: Emit the laser towards the target object, measure the time for the laser to travel back and forth, and calculate the distance by multiplying the recorded time and the velocity of light. The laser is characterized by such merits as high directivity, monochromaticity, and power, which play critical roles in measuring a long distance, judging the target object's direction, raising the reception system's SNR, and guaranteeing the measurement accuracy. With these features, laser distance meters receive growing attention. Laser radars, which have been developed based on laser distance meters, measure not only distances but also the target object's direction, movement velocity, and acceleration.
