Description

一种酒店防疫消毒用手持式电动静电喷雾枪A hand-held electric electrostatic spray gun for hotel epidemic prevention and disinfection 技术领域technical field
本发明涉及静电喷雾领域，尤其涉及一种酒店防疫消毒用手持式电动静电喷雾枪。The invention relates to the field of electrostatic spraying, in particular to a hand-held electric electrostatic spraying gun for hotel epidemic prevention and disinfection.
背景技术Background technique
静电喷雾的特点和优点在于它喷出雾液具有显著的环抱吸附效果。关于如何使喷出的雾液跟靶标和高压静电发生器的高压输出端之间形成一个闭合的电流回路，是实现静电喷雾良好的环抱吸附效果的必要一环，而其中良好的接地措施和方法就具有十分重要的地位，采用正确又良好的接地措施就能保证在人身安全和操控舒适的前提下实现雾液显著的环抱吸附效果，反之，则会影响到操作者的人身安全和舒适性以及喷雾的环抱吸附效果。The characteristic and advantage of electrostatic spray is that it sprays the mist liquid with remarkable encircling adsorption effect. How to form a closed current loop between the sprayed mist liquid and the target and the high-voltage output end of the high-voltage electrostatic generator is a necessary part of realizing the good encircling and adsorption effect of electrostatic spraying, and good grounding measures and methods. It has a very important position. Using correct and good grounding measures can ensure that the fog and liquid have a significant encircling adsorption effect under the premise of personal safety and comfortable operation. On the contrary, it will affect the personal safety and comfort of the operator. The encircling adsorption effect of the spray.
现有的各种手持式静电喷雾枪，有的采用感应荷电的方式对液体进行充电，但不设置静电接地装置，未形成电流闭合回路，这样虽然对操作者来说，人身的安全和舒适性得到了保证，但却严重影响了喷雾的环抱吸附效果的实现，使得静电喷雾器变的有名无实。有的虽也采用了直接接触的方式对液体进行充电，同时也设置了接地装置，但其接地装置还是采用将高压静电发生器的高压输出的一端与金属电极片相连接，静电喷雾器在工作时通过人的肢体表皮直接与金属电极片接触，从而通过人体导通静电高压，将静电荷通过人体与大地传导到靶标物上，使靶标物带上与雾液中所带的相反电荷，从而实现喷雾的环抱吸附效果。这种直接通过人体导通高压静电接地的方法虽然有 效，但却存在着诸多弊端：一是容易使操作人员肢体上积聚过多的静电荷而产生静电放电刺激的不安全不舒适的现象；二是当操作人员在进行防疫消毒操作时根据需要穿上防护工作服和戴上防护手套时，由于人体肢体的表皮不能直接与喷雾器上的金属接地电极良好接触，从而使得金属电极的接地失去了作用，因而也直接影响了静电喷雾环抱吸附效果的实现。而在卫生防疫的消毒杀菌工作中，往往需要工作人员穿上防护工作服和戴上防护手套，这样，如采用金属电极人体表皮直接接触接地的静电喷雾，就会使这台静电喷雾器失去了环抱吸附效果而实际变成为了一台普通的电动喷雾器。Some of the existing handheld electrostatic spray guns use inductive charging to charge the liquid, but do not set up an electrostatic grounding device, and do not form a current closed loop, so although the operator is safe and comfortable. The performance is guaranteed, but it seriously affects the realization of the encircling adsorption effect of the spray, which makes the electrostatic sprayer become only in name. Although some also use direct contact to charge the liquid, and also set up a grounding device, but the grounding device still uses one end of the high-voltage output of the high-voltage electrostatic generator to be connected to the metal electrode sheet. When the electrostatic sprayer is working Through the direct contact with the metal electrode sheet through the human body epidermis, the electrostatic high voltage is conducted through the human body, and the static charge is conducted to the target through the human body and the ground, so that the target is charged with the opposite charge to that in the mist, so as to realize The encircling adsorption effect of the spray. Although this method of directly conducting high-voltage electrostatic grounding through the human body is effective, it has many drawbacks: first, it is easy to accumulate too much electrostatic charge on the operator's limbs, resulting in the unsafe and uncomfortable phenomenon of electrostatic discharge stimulation; second When the operator puts on protective work clothes and protective gloves as needed during epidemic prevention and disinfection operations, because the epidermis of the human body cannot directly contact the metal grounding electrode on the sprayer, the grounding of the metal electrode loses its effect. Therefore, it also directly affects the realization of the electrostatic spray encircling adsorption effect. In the disinfection and sterilization work of sanitation and epidemic prevention, staff are often required to wear protective work clothes and protective gloves. In this way, if a metal electrode is used to directly contact the grounded electrostatic spray, the electrostatic sprayer will lose its encircling adsorption. The effect actually becomes an ordinary electric sprayer.
由于现有的手持式电动静电喷雾器所采用的上述相关技术在实际应用中存在着诸多的缺陷和问题，因此，研制和设计一种新的对应技术来解决和弥补上述的不足之处，使这类静电喷雾器能更好地发挥出积极的作用，既能确保静电喷雾环抱吸附效果的良好实现，又能更好的保障操作者的安全和操控舒适感，就显得十分重要和必要。Since the above-mentioned related technology adopted by the existing hand-held electric electrostatic sprayer has many defects and problems in practical application, a new corresponding technology is developed and designed to solve and make up for the above-mentioned shortcomings, so that this The electrostatic sprayer can play a more positive role, which can not only ensure the good realization of the adsorption effect of electrostatic spraying, but also better ensure the safety and comfort of the operator, which is very important and necessary.
发明内容SUMMARY OF THE INVENTION
为了解决上述技术问题，本发明公开了一种酒店防疫消毒用手持式电动静电喷雾枪，所述手持式电动静电喷雾枪包括：握持部；供人体手部握持；高压静电发生器，用于产生高压静电；液体充电电极，与所述高压静电发生器的一端连接，并用于对待雾化的液体施加静电电荷；电离接地电极，与所述高压静电发生器的另一端连接，所述电离接地电极设置于所述握持部上或邻近所述握持部设置，所述电离接地电极具有暴露在空气中的放电端，以能够对周围空气进行电离，所述放电端周围设有绝缘防护部件，以在人体手部握持所述握持部时对 人体手部进行防护。In order to solve the above technical problems, the present invention discloses a hand-held electric electrostatic spray gun for hotel epidemic prevention and disinfection. The hand-held electric electrostatic spray gun includes: a holding part; to generate high-voltage static electricity; the liquid charging electrode is connected to one end of the high-voltage electrostatic generator, and is used to apply electrostatic charge to the liquid to be atomized; the ionization ground electrode is connected to the other end of the high-voltage electrostatic generator, and the ionization ground electrode is connected to the other end of the high-voltage electrostatic generator. The ground electrode is arranged on or adjacent to the grip portion, the ionization ground electrode has a discharge end exposed to the air, so as to be able to ionize the surrounding air, and an insulating protection is provided around the discharge end The component is used to protect the human hand when the human hand holds the holding part.

关于电离接地电极12，其设置在握持部13处或握持部13附近，并且与高压静电发生器1的负极端或正极端连接，电离接地电极12具有位于壳体11外部的暴露在空气中的放电端，以能够通过放电对周围空气进行电离，使得空气带上另一种极性的静电电荷。另外，为了在人体手部握持所述握持部时对人手进行防护，在放电端周围可以设有绝缘防护部件。Regarding the ionization ground electrode 12 , which is provided at or near the grip portion 13 and is connected to the negative terminal or the positive terminal of the high-voltage electrostatic generator 1 , the ionization ground electrode 12 has a surface exposed to the air located outside the casing 11 . The discharge end can ionize the surrounding air through the discharge, so that the air is charged with another polarity of electrostatic charge. In addition, in order to protect the human hand when the human hand holds the holding portion, an insulating protective member may be provided around the discharge end.
参见图2，其示出了电离接地电极12的结构图。在图2中，电离接地电极采用碳纤电线121，其一端通过耐高压导线与高压静电发生器的输出端连接，另一端设置为开放型放电端122，也即去除***的纤维丝群，从而方便电极能够有效地对空气进行放电，增强电离效果。Referring to FIG. 2, a block diagram of the ionization ground electrode 12 is shown. In Fig. 2, the ionization ground electrode adopts carbon fiber wire 121, one end of which is connected to the output end of the high-voltage electrostatic generator through a high-voltage resistant wire, and the other end is set as an open discharge end 122, that is, the fiber filament group that has been removed from the foreskin, so as to facilitate The electrodes can effectively discharge the air and enhance the ionization effect.

此外，现有的手持式电动静电喷雾器中设置的液体充电电极，由于需要同高压导线采用锡焊的方法相连接，所以往往都采用了铜质等 金属材料制成。但铜质材料的电极如果长期与带有腐蚀性的消毒液体接触释放静电荷，在消毒液体对铜质等金属材料的腐蚀和静电荷的放电电解的双重作用下，容易使铜质等金属材料电解腐蚀生锈在电极的表面形成氧化腐蚀层面，从而影响电极的使用寿命和对液体的良好充电作用，进而影响到喷雾的环抱吸附效果。In addition, the liquid charging electrodes provided in the existing hand-held electric electrostatic sprayers are often made of metal materials such as copper because they need to be connected to the high-voltage wires by soldering. However, if the electrode made of copper material is in contact with the corrosive disinfectant liquid for a long time to release electrostatic charge, under the dual action of the disinfection liquid's corrosion on copper and other metal materials and the discharge and electrolysis of electrostatic charge, it is easy to make copper and other metal materials. Electrolytic corrosion and rusting form an oxidative corrosion layer on the surface of the electrode, which affects the service life of the electrode and the good charging effect of the liquid, thereby affecting the surrounding adsorption effect of the spray.
为此，在本发明进一步的实施方式中，液体充电电极4采用碳纤电线。该碳纤电线的一端通过耐高压导线与高压静电发生器的输出端连接、另一端为与待雾化的液体直接接触的放电端，该放电端为暴露的碳纤维丝群。To this end, in a further embodiment of the present invention, the liquid charging electrode 4 adopts a carbon fiber wire. One end of the carbon fiber wire is connected to the output end of the high-voltage electrostatic generator through a high-voltage resistant wire, and the other end is a discharge end that is in direct contact with the liquid to be atomized, and the discharge end is an exposed carbon fiber filament group.

Among them, the liquid charging electrode 4 adopts a carbon fiber wire 41 surrounded by rubber and is assembled in a special plastic three-way housing 40 . Among them, the upper and lower ends of the tee housing 40 are respectively designed with plugs 43 for connecting water pipes, and the carbon fiber wire 41 with the sheath is pre-buried in the tee housing 40, and a small part of the front end of the carbon fiber wire 41 is stripped. The discharge end 42 exposing the carbon filament as the liquid charging electrode is arranged in the middle of the interior of the three-way housing 40 .
另外，更进一步地，如图1所示，水泵2的出水端通过出水管路(例如，液流软管)5与喷头6相连接，喷头6上可设置有螺纹结构，以能方便地安装不同雾滴粒径粗细的金属喷嘴7，金属喷嘴7可选用不锈钢的材质，其既不易磨损，又耐腐蚀，而且还具有强化雾液带电的作用。In addition, further, as shown in FIG. 1 , the water outlet end of the water pump 2 is connected to the spray head 6 through a water outlet pipeline (eg, a liquid flow hose) 5, and the spray head 6 may be provided with a threaded structure for convenient installation. The metal nozzles 7 with different particle sizes of the droplets can be made of stainless steel, which is not easy to wear, but also resistant to corrosion, and also has the effect of strengthening the charging of the mist.
为了方便用户操作，本发明的手持式电动静电喷雾枪的枪身小巧，并配有专用的小型高压静电发生器和小型无刷水泵，节能又减少噪音。另外，储液箱设计为容量为750毫升左右并带有锁紧装置，喷嘴采用方便替换安装的设计，锂电池采用小型的滑插型电池包。In order to facilitate the user's operation, the hand-held electric electrostatic spray gun of the present invention has a small gun body, and is equipped with a special small high-voltage electrostatic generator and a small brushless water pump, which saves energy and reduces noise. In addition, the liquid storage tank is designed with a capacity of about 750 ml and has a locking device, the nozzle is designed for easy replacement and installation, and the lithium battery adopts a small sliding-insertion battery pack.
本发明的手持式电动静电喷雾枪的操作方式如下：The operation mode of the hand-held electric electrostatic spray gun of the present invention is as follows:
当开关启动接通电源，水泵和高压静电发生器同时开始工作，水泵的进水端通过自吸功能顺着进水管路从储液箱中吸入液体，液体在管路的流通过程中接触到充电电极时，瞬间就让液体带上较大能量的静电荷。带电的液体经过水泵的泵室加压后，经出水管路和喷头在金属喷嘴处挤压喷出，形成带有一种极性静电荷的带电群体雾滴。同时高压静电发生器高压输出端的另一极性高压电流，经耐高压导线传导至非直接接触型的电离接地电极，由于该电极的放电端是采用成百上千根纤细的碳纤维丝制作而成，众多的碳纤维丝的尖端暴露在空气中，将高压静电发生器输入的高压静电电流源源不断的对空气进行放电，使空气电离，从而可有效地将一种极性的静电荷通过空气传导到靶标物上，使靶标物顺利地带上另外一种极性的静电荷。同时，由于该接地电极安装在喷枪握把的人手抓握位置的附近，其虽不会直接与人体肢体表皮相接触，但由于相距很近，电极发射出的静电荷很容易通过空气间接传导到人体和肢体的表皮，这样又能通过人体传导接地的途径将静电荷传导到靶标物上，使靶标物带上静电荷，因此，使高压静电接地的可靠性和稳定性得到了有效的提升。When the switch is turned on and the power is turned on, the water pump and the high-voltage electrostatic generator start to work at the same time. The water inlet of the water pump sucks the liquid from the liquid storage tank along the water inlet pipeline through the self-priming function, and the liquid contacts the charging during the circulation of the pipeline. When the electrode is connected, the liquid is charged with a large energy electrostatic charge in an instant. After the charged liquid is pressurized by the pump chamber of the water pump, it is squeezed and sprayed at the metal nozzle through the water outlet pipeline and the nozzle, forming a charged group droplet with a polar electrostatic charge. At the same time, the high-voltage current of the other polarity of the high-voltage output end of the high-voltage electrostatic generator is conducted to the non-direct contact ionization ground electrode through the high-voltage resistant wire. Because the discharge end of the electrode is made of hundreds of thin carbon fiber filaments , the tips of many carbon fiber filaments are exposed to the air, and the high-voltage electrostatic current input by the high-voltage electrostatic generator continuously discharges the air to ionize the air, thereby effectively conducting a polar electrostatic charge through the air to the air. On the target, the target is smoothly charged with another polarity of electrostatic charge. At the same time, since the ground electrode is installed near the gripping position of the hand of the spray gun, although it will not be in direct contact with the epidermis of the human body, due to the close distance, the electrostatic charge emitted by the electrode is easily conducted indirectly through the air. The epidermis of the human body and limbs can also conduct electrostatic charge to the target through the way of human body conduction grounding, so that the target is charged with electrostatic charge. Therefore, the reliability and stability of high-voltage electrostatic grounding have been effectively improved.
综上所述：当水泵经喷嘴喷出的带有一种极性的静电荷的带电雾滴，在外力推送、地球引力和电场力的多重作用下，沉降到靶标物附近时，由于该靶标物经过非直接接触型的电离接地电极的空气电离传导和人体非接触型传导的双重传导下，已经有效地带上了另外一种极性的静电荷。因此，当带有一种极性静电荷的动态带电雾滴沉降靠近到带有另外一种极性静电荷的静态靶标物时，在异性电荷相互吸引的作用下，动态带电雾滴就会快速地奔向静态的带电靶标物，从而牢牢 地吸附在靶标物的上下左右，形成良好的环抱吸附效果。To sum up: when the charged mist droplets with a polarity of electrostatic charge ejected by the pump through the nozzle settle near the target under the multiple actions of external force, earth's gravitational force and electric field force, due to the Under the double conduction of the air ionization conduction of the non-direct contact ionization ground electrode and the non-contact conduction of the human body, the electrostatic charge of another polarity has been effectively brought. Therefore, when a dynamically charged droplet with one polarity electrostatic charge settles and approaches a static target with another polar electrostatic charge, the dynamically charged droplet will rapidly move under the attraction of opposite charges. Run towards the static charged target, so as to be firmly adsorbed on the top, bottom, left and right of the target, forming a good encircling adsorption effect.
本发明的手持式电动静电喷雾枪采用非金属充电电极和双重非直接接触接地电流闭合回路，该喷雾枪改变了原来采用铜等金属材料制成的直接液体接触充电电极和采用人体表皮直接接触传导高压静电接地的做法，而是创新地采用了非金属的耐腐蚀的碳纤维丝电极和双重非人体直接接触式的接地方法，将静电荷传导到靶标物上，同样使之形成完整的电流闭合回路，从而既确保了静电喷雾的良好环抱吸附效果的实现，又能确保操作者的人身安全和舒适感，从而消除了现有技术的诸多弊端。The hand-held electric electrostatic spray gun of the present invention adopts non-metallic charging electrodes and double non-direct contact grounding current closed loops. The high-voltage electrostatic grounding method innovatively adopts non-metallic corrosion-resistant carbon fiber wire electrodes and double non-human body direct contact grounding methods to conduct electrostatic charge to the target, which also forms a complete current closed loop. , thereby not only ensuring the realization of the good encircling adsorption effect of the electrostatic spray, but also ensuring the personal safety and comfort of the operator, thereby eliminating many drawbacks of the prior art.
