Problems solved by technology

However, these applications are all carried out under the premise that the liquid flow power is given by the outside world, so the application of the solenoid flow tube technology is limited. If the additional power source is an electromagnetic motor, it cannot be used in some electromagnetically sensitive places, and In the environment where precise control of fluid flow is required, it cannot meet the requirements

Abstract

The invention relates to a valveless piezoelectric pump with lituus flow pipes. The valveless piezoelectric pump comprises a pump body consisting of an upper cover and a lower cover which are connected hermetically, a pump cavity containing a piezoelectric vibrator is arranged between the upper cover and the lower cover, a first lituus flow pipe and a first straight flow pipe are also arranged between the upper cover and the lower cover, one end of the first lituus flow pipe is connected with the pump cavity, the other end of the lituus flow pipe is connected with a fluid inlet arranged on the pump body, one end of the straight flow pipe is connected with the pump cavity, and the other end of the straight flow pipe is connected with a fluid outlet arranged on the pump body. The valveless piezoelectric pump provided by the invention is equipped with the lituus flow pipes instead of the traditional conical flow pipes, the working principle of the piezoelectric pump is changed; compared with the traditional valveless piezoelectric pump, the valveless piezoelectric pump provided by the invention has good unidirectional flowability, the energy loss of flowing fluid is reduced and the working efficiency of the pump is improved. For being manufactured conveniently, all the lituus flow pipe used in the valveless piezoelectric pump have rectangular sections.

Description

technical field [0001] The invention relates to a valveless piezoelectric pump, in particular to a valveless piezoelectric pump adopting interlocking spiral flow tubes. Background technique [0002] The classification of piezoelectric pumps can be roughly divided into positive displacement pumps and rotary pumps. At present, most piezoelectric pumps are volumetric pumps. According to the presence or absence of pump valves, piezoelectric pumps can be divided into piezoelectric pumps with valves and piezoelectric pumps without valves, such as figure 1 The valved piezoelectric pump is shown. When it is working, the reciprocating vibration of the piezoelectric vibrator causes the periodic change of the volume of the pump chamber, and the change of the volume causes the change of the pressure in the pump chamber, which controls the opening and closing of the pump valve. Because the vibration amplitude of the piezoelectric vibrator of the valved piezoelectric pump is very small, ...
