The application discloses a kind of bubble generator and hydraulic floatation equipment, belong to mineral processing technical field, solve the problem that separation effect is poor in prior art due to larger bubble scale.The bubble generator, including gas supply unit, flow dividing tee, gas chamber and microwell plate;Flow dividing tee has mutually communicating air inlet branch, emptying branch and gas supply branch;The air outlet of gas supply unit is communicated with air inlet branch, emptying branch is communicated with external environment, and gas supply branch is communicated with gas chamber;Microwell plate is located at the air outlet end of gas chamber.The bubble generator and hydraulic floatation equipment can be used for hydraulic floatation.

The application provides an integrated cooker, which comprises a cooking table and a machine head, the machine head is arranged at the rear end of the cooking table, the machine head has a flue, the flue comprises a first inner wall surface away from the cooking table and a second inner wall surface close to the cooking table, the front-to-rear distance between the first inner wall surface and the second inner wall surface is a first width, and the first width of the flue first increases and then decreases along the left-to-right direction; the integrated cooker is beneficial to reducing the airflow disorder degree of oil fume when the oil fume flows in the flue, thereby being beneficial to improving the oil fume suction effect of the integrated cooker and reducing the noise when the oil fume is sucked.

The utility model discloses an air fryer which comprises a machine body and a fryer body, a hot air assembly is arranged in the machine body, the hot air assembly comprises a heating piece and a hot air fan, the fryer body is provided with a cooking cavity, the hot air assembly conveys hot air to the cooking cavity to heat food materials, and a reflecting cover arranged above the cooking cavity in a covering mode is further arranged in the machine body. The side wall of the reflection cover is provided with an air inlet, fresh air entering from the air inlet blows to the heating piece, electric fan blades and an air guide cover extending up and down are further arranged in the machine body, and the air guide cover and the reflection cover define a fresh air channel with the cross section being large in the upper portion and small in the lower portion. The utility model provides an air fryer which achieves the effect of actively conveying fresh air into a cooking cavity.

This utility model discloses a heat exchanger and an air conditioner having the same. The heat exchanger includes a heat exchange section and an inlet section. The heat exchange section has multiple refrigerant channels, and the inlet section includes a main pipe and multiple branch pipes. The branch pipes are connected to the multiple refrigerant channels. The two ends of the main pipe are an upstream end and a downstream end, respectively. The branch pipes are spaced apart along the length of the main pipe and are all connected to the main pipe. The main pipe has a reduced diameter section, and the flow area of ​​the main pipe decreases at the reduced diameter section from the upstream end to the downstream end. At least one branch pipe is arranged upstream and downstream of the reduced diameter section. In the above technical solution, the inlet section has a simple structure, does not require a distributor, occupies little space, is easy to arrange, and can save production and assembly costs. Furthermore, by setting a reduced diameter section in the main pipe of the inlet section, the flow velocity of the refrigerant flowing through the reduced diameter section increases, the dynamic pressure increases, and the static pressure decreases, resulting in a more balanced flow rate in the branch pipes along the main pipe, which is beneficial to improving the heat exchange effect of the heat exchanger.
