Abstract At present, the expansion of the output performance of the piezoelectric pump is a research hotspot. This paper presents a valve-less piezoelectric pump with double cone-shaped tubes. First of all, by analyzing the working processes and calculation formulas, the efficiency is higher and the output performances are better when the ratio of the forward and reverse pressure loss coefficient is larger. Moreover, a series of valve-less piezoelectric pump with the parameters of the number of cone-shaped tube at single, double and triple, the diameter (M) of the diffuser at 6.5 mm, 7.0 mm, 7.5 mm, 8.0 mm and 8.5 mm, the angle (A) at 15°, 17.5°, 20° and 22.5° are fabricated. At last, the output flow rate and pressure are tested. The results show that the output flow rate reaches a maximum of 146.4 mL/min at the parameters of double coneshaped tubes, the diameter (M) 7.0 mm and the angle (A) 20° under the driving voltage 220 V and a frequency 68 Hz, the highest pressure is 520 Pa, the efficiency (g) is largest.
1 Introduction In recent years, valve-less piezoelectric pumps have been greatly favored by scholars (Huang et al. 2016; He et al. 2019). It is applied in the fields including drug delivery system (Tandon et al. 2016; Chen et al. 2019; Gidde et al. 2020), fuel cells (Ma et al. 2008), cooling systems for electronic components (Liu et al. 2020) and the robots (Hu and Hongliu 2018) due to the advantages of the small energy consumption (Wang et al. 2009), high electro-hydraulic conversion efficiency (Tseng et al. 2013) and simple structure (Chandika et al. 2012; Erik and Go¨ran 1993; Tang et al. 2019). Valve-less piezoelectric pumps make simple and save costs comparing with the valve piezoelectric pump (Taijiang et al. 2019; Dong et al. 2019; Yang et al. 2019). However, the output performance limits the application of piezoelectric pumps.

Structural design plays a very important role in the flow rate of piezoelectric pump. The nozzle/diffuser configuration is very beneficial to the output performance of valveless piezoelectric pumps (Anders et al. 1996, 2000; Jiang et al. 1998). In 1993, Erik and Go¨ran (1993) designed and tested a new valve-less cone-shapedfluid pump,and it has a maximum flow rate of 16 mL/min and a maximum pressure of 2 mm H2O at 100 Hz. In 1998, Amos (1998) fInds that a series connection is usually advantageous to a parallel connection even to increase the flow rate.Subsequently, in
