2results about How to "Running does not affect" patented technology

The utility model discloses a massage mechanism running track structure of convertible massage bed or chair, and the front end of electric massage mechanism is equipped with running gear, and running gear is installed on the gear strip to make electric massage mechanism can reciprocating operation, and the bottom of the rear end of electric massage mechanism is installed with upper guide pulley, and the flexible guide rail is the flexible metal strip or plastic strip, and is installed below the gear strip, and the both sides of guide pulley frame are installed with lower guide pulley, and the upper guide pulley of electric massage mechanism is through the lower guide pulley cooperation of guide pulley frame and installs the flexible guide rail, makes it when running not deviate, and angle adjusting mechanism is adjusted into massage bed mode or massage chair mode through controller, the utility model discloses realized massage bed or massage chair in electric adjusting backrest angle's time not to influence electric massage mechanism operation, can lie down massage and can sit and massage, greatly promote user use experience, adapt to more use scene simultaneously, and one thing two use cost performance is higher, and the production cost is low, and it is favorable to the popularization and application.

The utility model provides a heat exchanger shunting device which solves the problems that a small-diameter radiating pipe is prone to scaling in the using process, the flow speed of fluid is affected, the heat exchange efficiency is reduced, frequent shutdown for cleaning and maintenance is needed, and equipment operation is affected. The double-flow-path reverse flow path is arranged to form two-time cross heat exchange with shell pass fluid, the heat exchange efficiency can be improved, the two flow channels are independent of each other, starting and stopping of the two flow channels can be freely adjusted according to the temperature requirement, energy is saved, meanwhile, single-side mechanical cleaning is allowed under the condition that operation is not stopped, and the heat exchange efficiency is improved. And the other side is maintained to operate, so that the downtime is reduced, the problem of scaling can be solved on the premise of not changing the pipe diameter and energy consumption, and meanwhile, the operation of equipment is not influenced.
