Problems solved by technology

However, the currently popular battery-powered membraneless electrolyzed water devices, especially mobile and portable membraneless electrolyzed water devices, generally have the problem of low battery power utilization efficiency, because these devices all use battery voltage converters (i.e. DC- DC converter), the battery voltage is transformed by the voltage converter, and then supplies power to the electrolytic electrode to meet the higher voltage required by the electrolytic water process. For example, the output voltage of a single lithium battery is about 4.2V, while the general membraneless electrolytic water process A voltage of about 30V is required, so the 4.2V voltage of the lithium battery needs to be raised to 30V through a DC-DC converter. This conversion makes the battery application efficiency lower than 30%, resulting in a great waste of battery energy and increasing environmental pollution.

Embodiment 1

[0015] See this example figure 1 , figure 1 Among them, 1 is the control circuit, 2 is 1 or N batteries in series, N is an integer greater than 1, 5 is the membraneless electrolysis water electrode assembly, the c terminal of the control circuit is connected to 2 and 5, and the g terminal is figure 1 The common terminal of the circuit, 6 is a switch controlled by the control circuit (it can be regarded as a part of the control circuit); when the control circuit 1 starts the device to perform electrolysis of water, it is connected from k to control 6, and Ucg directly supplies power to 5 with high efficiency through 6 (6 The power loss is low and can be ignored); the electrode assembly 5 electrolyzes the water in the electrode gap after being energized. The number of batteries connected in series, that is, the value of N, can be appropriately selected in an integer range greater than 1 according to the characteristics of the membraneless electrolysis electrode assembly and the...

Embodiment 2

[0020] See this example figure 2 As shown, the same parts as in Embodiment 1 will not be described in detail. The dotted line box 1 in the figure is a control circuit, 8 in 1 is a charging IC that outputs a fixed charging voltage Uco, and 2 is N batteries in series (N is an integer greater than 1). 9 is the stable voltage Uwg, the w terminal is connected to the o terminal, and the g point is figure 1 The common terminal of the circuit, the high voltage terminal of N series batteries 2 is connected to the positive pole C of Uco, and the low voltage terminal is connected to point g of Uwg, the charging voltage of the series battery is Ucg=Uco+Uwg, because the range of the charging voltage Uco output by the charging IC is fixed , so changing Uwg can change Ucg to reach the charging voltage required by N batteries connected in series.

[0021] In general, the required charging voltage Ucg is greater than Uco, so Uwg and Uco are selected to have the same polarity, and the actual ...

Abstract

An efficient water electrolysis device in which one or N batteries connected in series directly supply power to water electrolysis electrodes is characterized by comprising one or N batteries connected in series, a membrane-free water electrolysis electrode assembly and a control circuit, wherein N is an integer larger than one, and the control circuit controls water electrolysis work to be started or stopped. In the water electrolysis process, the batteries are controlled by the control circuit and directly supply power to the membrane-free water electrolysis electrode assembly without voltage transformation, and water in anodic and cathodic gaps of the electrode assembly is electrolyzed. When a charging device is adopted for the efficient water electrolysis device or a charging circuit is arranged in the efficient water electrolysis device to charge the batteries or an external charger charges the batteries, a simple and convenient method that charging IC actual charging voltage is changed through series connection of one stable voltage can be adopted, an IC can charge the N batteries connected in series, and charging quality is improved. The batteries connected in series for charging or positive and negative electrodes of part of the batteries are connected with voltage amplitude limiting circuits respectively in parallel, charging voltage of each battery is limited to meet the requirement, or charging balance of the batteries connected in series is achieved.
