Description

Technical Field

[0001] The invention belongs to the field of water purification and treatment, and in particular relates to a self-powered high-electric field sterilizing water dispenser. Background Art

[0002] Water is the source of life, without water there is no life. Bacterial contamination of drinking water can lead to a variety of health problems, such as digestive system diseases, respiratory system diseases, immune system diseases, fetal malformations in pregnant women, etc. Therefore, the safety of drinking water has always been a key issue of concern to the country.

[0003] Common drinking water sterilization technologies are mainly chemical (such as chlorination, bleaching powder, ozone) treatment and high-temperature sterilization. Chemical sterilization will inevitably introduce some harmful substances, and the concentration of introduced impurities needs to be strictly controlled. For example, chloride ions may cause digestive system problems. High-temperature sterilization is a common sterilization method for household water dispensers, which usually requires heating by electric energy. High-temperature sterilization and chemical sterilization methods face huge challenges in some remote areas without electricity, areas without power after natural disasters, outdoor environments and power outages.

[0004] Electric field sterilization is a sterilization technology that does not require the introduction of foreign substances. It uses a strong electric field to destroy the cell membrane of bacteria to achieve bacterial inactivation. Traditional electric field sterilization equipment is large in size, complex in structure, and expensive, and is usually used in factory sewage treatment.

[0005] Therefore, there is an urgent need to prepare an electric field sterilization device with a small size, simple structure and low price that can be used in remote areas without electricity, areas without power after natural disasters, outdoor environments and power outage environments to ensure the safety of drinking water. Summary of the invention

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A self-powered high electric field sterilization water dispenser, comprising:

[0008] A box body, wherein the box body has an independently arranged water inlet tank, a purification tank and a water outlet tank, and the water outlet tank is connected to an external water outlet member;

[0009] A sterilization pipe, the sterilization pipe is arranged in the purification tank, the water inlet end of the sterilization pipe is communicated with the water inlet tank, and the water outlet end of the sterilization pipe is connected with the water outlet tank;

[0010] A hand-cranked rotating friction nanogenerator, wherein the hand-cranked rotating friction nanogenerator is arranged on the side wall of the purification tank;

[0011] A boost circuit is arranged on the hand-cranked rotating friction nanogenerator, the input end of the boost circuit is connected to the output end of the hand-cranked rotating friction nanogenerator, and the output end of the boost circuit is connected to the sterilization tube, for generating a high-intensity uniform electric field in the tube.

[0012] Furthermore, the sterilization tube is a spiral tube.

[0013] Furthermore, the sterilization tube comprises an inner solid tube and an outer hollow tube, wherein the inner solid tube is arranged at the center of the inner cavity of the outer hollow tube; wherein the diameter of the inner solid tube is smaller than the diameter of the outer hollow tube, so that water flows through the gap between the inner solid tube and the outer hollow tube;

[0014] The inner solid tube and the outer hollow tube are respectively connected to the positive electrode and the negative electrode of the output end of the boost circuit.

[0015] Furthermore, the inner solid tube is composed of an inner conductive tube and an inner insulating tube from the inside to the outside;

[0016] The outer hollow tube is composed of an outer insulating tube, an outer conductive tube and an outer insulating layer from the inside to the outside;

[0017] The internal conductive tube and the external conductive tube are respectively connected to the positive electrode and the negative electrode of the output end of the boost circuit.

[0018] Furthermore, the hand-cranked rotary friction nanogenerator includes an electronegative material, a conductive electrode, a connecting shaft and a handle;

[0019] The conductive electrode and the electronegative material are respectively mounted on insulating hard plate discs, and the conductive electrode is arranged on the side wall of the purification tank; the electronegative material is connected to the first end of the connecting shaft, and the second end of the connecting shaft passes through the conductive electrode and the side wall of the purification tank and is connected to the handle; wherein the conductive electrode and the side wall of the purification tank are rotatably connected to the connecting shaft;

[0020] The boost circuit is arranged on a side of the conductive electrode away from the electronegative material.

[0021] Furthermore, the electronegative material is composed of two sectors consisting of quarter circles arranged opposite to each other.

[0022] Furthermore, the conductive electrode is formed by enclosing a sector consisting of four quarter circles, wherein two opposite sectors are connected by wires, and the two opposite sectors serve as two electrodes respectively.

[0023] Furthermore, the hand-cranked rotating friction nanogenerator can also be one of a multilayer hand-cranked rotating friction nanogenerator, a charge-excited hand-cranked rotating friction nanogenerator and a hand-cranked rotating electromagnetic-friction hybrid power generation nanogenerator.

[0024] Beneficial effects:

[0025] (1) When the self-powered high electric field sterilizing water dispenser of the present invention is working, the hand-cranked rotating friction nanogenerator and the boost circuit provide high voltage to the sterilizing tube. The electric field strength is equal to the voltage divided by the distance d between the inner metal tube and the outer metal tube of the sterilizing tube (E=V / d). Through circuit design and optimization of the sterilizing tube structure, we can easily obtain an electric field strength of 30-120 kV / m inside the sterilizing tube. Such a high electric field strength can quickly inactivate bacteria in water.

[0026] (2) The metal tubes inside and outside the sterilization tube are completely insulated. Therefore, it is only necessary to start providing rotational energy. The voltage of the metal tubes inside and outside the sterilization tube can reach saturation within a few rotation cycles. After the voltage is saturated, even if the hand-cranked friction nanogenerator stops working, the sterilization tube can maintain a high electric field strength for a long time and continuously sterilize the water flowing through.

[0027] (3) The self-powered high electric field sterilization drinking water machine described in the present invention has a simple structure, low cost, and does not require an additional power supply. It can be used in some remote areas without electricity, areas without power after natural disasters, field environments, and power outage environments, which is more conducive to industrial promotion and application.

[0046] In this embodiment, the external water outlet is a faucet.

[0047] Example 2

[0048] refer to Figure 4-Figure 5 In order to ensure that the water flow is fully purified in the purification tank, this embodiment is further configured on the basis of embodiment 1.

[0049] Preferably, the sterilization tube 3 is a spiral tube.

[0050] In this embodiment, the spiral pipeline has an outer diameter of 35 cm and a height of 35 cm.

[0051] Preferably, the sterilization tube 3 comprises an inner solid tube 31 and an outer hollow tube 32, wherein the inner solid tube 31 is arranged at the center of the inner cavity of the outer hollow tube 32; wherein the diameter of the inner solid tube 31 is smaller than the diameter of the outer hollow tube 32, so that the water flows through the gap between the inner solid tube 31 and the outer hollow tube 32;

[0052] The inner solid tube 31 and the outer hollow tube 32 are connected to the positive electrode and the negative electrode of the output end of the boost circuit 5 respectively.

[0053] Preferably, the inner solid tube 31 includes an inner conductive tube 311 and an inner insulating tube 312 from the inside to the outside;

[0054] The outer hollow tube 32 includes an outer insulating tube 321, an outer conductive tube 322 and an outer insulating layer 323 from the inside to the outside.

[0055] The internal conductive tube 311 and the external conductive tube 322 are respectively connected to the positive electrode and the negative electrode of the output end of the boost circuit 5 .

[0056] In this embodiment, the outer diameter of the inner conductive tube is 0.5 cm, the outer diameter of the inner insulating tube is 0.8 cm, the outer diameter of the outer insulating tube is 1.4 cm, the outer diameter of the outer conductive tube is 1.5 cm, and the outer insulating layer is 1.8 cm.

[0058] In this embodiment, due to the small spacing design between the inner conductive tube 311 and the outer conductive tube 322, according to the electric field strength formula E=V / d (E is the electric field strength inside the tube, V is the potential difference between the inner conductive tube and the outer conductive tube, and d is the spacing between the inner conductive tube and the outer conductive tube), a relatively large electric field strength can be generated between the inner conductive tube 311 and the outer conductive tube 322. The water flows through between the inner insulating tube and the outer insulating tube, and is sterilized by the strong electric field to obtain sterile water.

[0059] Example 3

[0063] The boost circuit 5 is disposed on a side of the conductive electrode 21 away from the electronegative material to save space.

[0064] In this embodiment, the output of the hand-cranked rotating friction nanogenerator 2 is connected to the boost circuit 5 to charge the diode in the boost circuit 5; when the output of the hand-cranked rotating friction nanogenerator 2 is large enough, the voltage across each diode used for boosting in the boost circuit 5 can be increased to twice the output voltage, and the inner and outer metal tubes of the sterilization tube 3 are connected to different numbers of boosted diodes, and an electric field strength of 30-120kV / m is generated inside the sterilization tube 3, and the water in the upper water tank flows through the sterilization pipe to achieve strong electric field sterilization; since the inner and outer metal tubes are insulated, the hand-cranked rotating friction nanogenerator stops working after working for several cycles, and the electric field strength inside the sterilization tube can be maintained for a long time, continuously sterilizing the water flowing through.

[0065] In this embodiment, the diameter of the hand-cranked rotating friction nanogenerator 2 is 15-35 cm.

[0066] In this embodiment, the boost circuit 5 adopts a 2-12 times voltage boost circuit. The reverse breakdown voltage of the high voltage diode used in the boost circuit 5 is 20000-30000V, and the capacitance is 2-50nF.

[0073] refer to Figure 6-Figure 7 This embodiment is an experimental case of applying the self-powered high electric field sterilization drinking water machine in Example 1.

[0074] The boost circuit 5 uses an 8-fold voltage circuit, and the analog voltage after boosting is as follows Figure 6 As shown. The simulated input voltage is 1500V, which is an output voltage that can be easily achieved by the hand-cranked friction nanogenerator 2. In the simulation, the 2x, 4x, 6x and 8x voltage circuits can boost the voltage to 3000V, 6000V, 8000V and 12000V, respectively. Considering that the spacing between the tubular electrodes is 1.0cm, the electric field strength inside the tube can reach 30kV / m, 60kV / m, 80kV / m and 120kV / m under the 2x, 4x, 6x and 8x voltage circuits, respectively.

[0075] The actual test boost data is as follows Figure 7As shown. The actual input voltage of the test is 450V. The boost circuit 5 is composed of several 6.8nF high-voltage ceramic capacitors and several diodes. In this case, we tested the actual boosting conditions of the 2-times voltage circuit, 4-times voltage circuit, 6-times voltage circuit and 8-times voltage circuit respectively. After connecting to the corresponding voltage doubling circuit, the voltage can rise to 730V, 1520V, 1950V and 2560V respectively in 60s. When the spacing between the tubular electrodes is 1.0cm, the corresponding electric field strength in the tube can reach 7.3kV / m, 15.2kV / m, 19.5kV / m and 25.6kV / m respectively.
