Description

Hotel epidemic prevention is electronic electrostatic spray rifle of hand-held type for disinfection

Technical Field

The invention relates to the field of electrostatic spraying, in particular to a handheld electric electrostatic spraying gun for epidemic prevention and disinfection of hotels.

Background

The electrostatic spraying has the characteristics and advantages that the sprayed mist has obvious surrounding adsorption effect. How to form a closed current loop between the sprayed mist and the target and the high-voltage output end of the high-voltage electrostatic generator is a necessary loop for realizing the good encircling adsorption effect of electrostatic spraying, wherein good grounding measures and methods have very important positions, the adoption of the correct and good grounding measures can ensure that the remarkable encircling adsorption effect of the mist is realized on the premise of personal safety and comfortable operation, and on the contrary, the personal safety and comfort of operators and the encircling adsorption effect of spraying are influenced.

Some of the existing various handheld electrostatic spray guns adopt an induction charging mode to charge liquid, but do not have an electrostatic grounding device and do not form a current closed loop, so that the personal safety and comfort are guaranteed for an operator, but the realization of the surrounding adsorption effect of the spray is seriously influenced, and the electrostatic spray guns are famous and unrealistic. Some liquid is charged in a direct contact mode, and meanwhile, an earthing device is also arranged, but the earthing device is also used for connecting one end of the high-voltage output of the high-voltage electrostatic generator with the metal electrode plate, and the electrostatic sprayer is directly contacted with the metal electrode plate through the human limb skin during working, so that the electrostatic high voltage is conducted through the human body, the electrostatic charge is conducted to a target object through the human body and the ground, the target object is charged with charges opposite to those in the fog liquid, and the surrounding adsorption effect of spraying is achieved. Although the method of conducting high-voltage static electricity to ground directly through the human body is effective, the method has a plurality of disadvantages: firstly, the phenomenon of unsafety and discomfort of electrostatic discharge stimulation caused by excessive electrostatic charge accumulated on the limbs of operators is easily caused; secondly, when the operator wears the protective working clothes and protective gloves according to the requirements during the epidemic prevention and disinfection operation, the skin of the limbs of the human body can not be directly in good contact with the metal grounding electrode on the sprayer, so that the grounding of the metal electrode is disabled, and the realization of the surrounding adsorption effect of the electrostatic spray is directly influenced. In the disinfection and sterilization work of epidemic prevention, workers are often required to wear protective working clothes and protective gloves, so that if the metal electrode is adopted to directly contact the human body skin with the grounded electrostatic spray, the electrostatic spray loses the surrounding adsorption effect and becomes a common electric spray.

Because the related technologies adopted by the existing handheld electric electrostatic sprayer have a plurality of defects and problems in practical application, a new corresponding technology is developed and designed to solve and make up the defects, so that the electrostatic sprayer can better play a positive role, the electrostatic sprayer can ensure the good realization of the surrounding adsorption effect of the electrostatic sprayer, and the safety and the control comfort of an operator can be better ensured, and the handheld electric electrostatic sprayer is very important and necessary.

Specifically, in one embodiment of the present invention, for example, referring to fig. 1, a hand-held electric electrostatic spray gun includes a housing 11, a lithium battery 3, a water pump 2, a high voltage electrostatic generator 1, a liquid charging electrode 4, a water pump suction line 9, a liquid storage tank 8, a water pump outlet line 5, a spray head 6, a spray nozzle 7, an operation switch 10, and an ionization ground electrode 12.

The housing 11 is made of an insulating material and may be formed, for example, by injection moulding, and similarly, the reservoir 8 may be blow moulded and may be snap fitted to the body of the spray gun. Of course, it will be appreciated that the reservoir 8 may also be formed integrally with the housing 11.

In the embodiment of fig. 1, the lithium battery 3 is mounted at the bottom of the holding part 13 of the plastic shell 11, and the high-voltage electrostatic generator 1 and the water pump 2 are mounted on the lithium battery, and the lithium battery is controlled by the control switch 10 to provide working power for the high-voltage electrostatic generator 1 and the water pump 2. The water inlet end of the water pump 2 is connected with a water inlet pipeline 9 which can be configured by a rubber pipe and is inserted into the water storage tank 8. The liquid charging electrode 4 is connected to the positive or negative terminal of the high voltage electrostatic generator 1 and contacts the liquid to be atomized to apply an electrostatic charge of one polarity to the liquid to be atomized, and in fig. 1, the liquid charging electrode 4 is installed on the suction line 9 to apply an electrostatic charge to the liquid flowing through the suction line. It will be appreciated that the liquid charging electrode 4 may also be provided in the reservoir 8 or on the water outlet line 5.

Of course, it is understood that the specific arrangement positions and manners of the above-mentioned respective components are only for illustration, and for example, the positions of the lithium battery 3, the high voltage electrostatic generator 1, the water pump 2, and the like can be flexibly adjusted.

Regarding the ionization ground electrode 12, which is provided at or near the grip portion 13 and is connected to the negative or positive terminal of the high voltage electrostatic generator 1, the ionization ground electrode 12 has a discharge end exposed to the air outside the housing 11 to enable ionization of the surrounding air by discharge so that the air is charged with electrostatic charges of the other polarity. In addition, in order to protect the hand of a human body when the holding part is held by the hand of the human body, an insulating protection component can be arranged around the discharge end.

Referring to fig. 2, a block diagram of the ionizing ground electrode 12 is shown. In fig. 2, the ionization ground electrode is a 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 of which is an open discharge end 122, i.e., a wrapped fiber group is removed, so that the electrode can discharge air effectively, and the ionization effect is enhanced.

In addition, as shown in fig. 2, an insulating bracket 123 is provided around the discharge end 122 (i.e., the conductive fiber filament exposed in the air) of the ionization ground electrode 12, so as to prevent the hand of the human body from touching the discharge end, thereby ensuring the safety of the human body, and the insulating bracket 123 may be fixed on or near the grip portion 13 by means of tight fitting and pressing.

Alternatively, as for the ionization ground electrode 12, a metal single-needle type ionization discharge structure may also be employed.

In addition, the liquid charging electrode arranged in the existing hand-held electric electrostatic sprayer is usually made of metal materials such as copper and the like because the liquid charging electrode needs to be connected with a high-voltage lead by adopting a soldering method. However, if the electrode made of copper material is contacted with the corrosive disinfection liquid for a long time to release static charge, under the dual actions of corrosion of the disinfection liquid to the metal materials such as copper and the like and discharge electrolysis of the static charge, the metal materials such as copper and the like are easy to corrode and rust by electrolysis to form an oxidation corrosion layer on the surface of the electrode, thereby influencing the service life of the electrode and the good charging effect on the liquid, and further influencing the surrounding adsorption effect of the spray.

To this end, in a further embodiment of the invention, the liquid charging electrode 4 employs carbon fiber wires. One end of the carbon fiber electric wire is connected with the output end of the high-voltage electrostatic generator through a high-voltage resistant lead, the other end of the carbon fiber electric wire is a discharge end which is in direct contact with liquid to be atomized, and the discharge end is an exposed carbon fiber yarn group.

As shown in fig. 3, a schematic view of the structure of the liquid charging electrode 4 is shown. The liquid charging electrode 4 adopts a carbon fiber wire 41 with the periphery coated with rubber and is assembled in a special plastic three-way shell 40. Wherein, the upper and lower both ends of three-way housing 40 are designed with the plug 43 that conveniently connects the water pipe respectively, and the carbon fiber electric wire 41 with the foreskin is pre-buried in three-way housing 40, exposes carbon fiber silk as the middle of liquid charging electrode's discharge end 42 setting in three-way housing 40 inside after the foreskin is peeled off to carbon fiber electric wire 41 front end a small part.

Furthermore, as shown in fig. 1, the water outlet end of the water pump 2 is connected to the nozzle 6 through a water outlet pipe (e.g., a liquid flow hose) 5, the nozzle 6 can be provided with a screw structure to conveniently mount metal nozzles 7 with different droplet sizes, the metal nozzles 7 can be made of stainless steel, which is not easy to wear and corrosion resistant, and has the function of enhancing the electrification of the mist.

In order to facilitate the operation of a user, the hand-held electric electrostatic spray gun has a small gun body, is provided with a special small high-voltage electrostatic generator and a small brushless water pump, saves energy and reduces noise. In addition, the liquid storage box is designed to have the capacity of about 750 milliliters and is provided with a locking device, the nozzle is designed to be convenient to replace and install, and the lithium battery adopts a small sliding-insertion type battery pack.

The handheld electric electrostatic spray gun of the present invention operates as follows:

when the switch is started to switch on the power supply, the water pump and the high-voltage electrostatic generator start to work simultaneously, the water inlet end of the water pump sucks liquid from the liquid storage tank along the water inlet pipeline through the self-suction function, and when the liquid contacts the charging electrode in the circulation process of the pipeline, the liquid is instantly charged with electrostatic charges with larger energy. The charged liquid is pressurized by a pump chamber of a water pump and then extruded and sprayed out at a metal nozzle through a water outlet pipeline and a spray head to form charged group fog drops with a polarity electrostatic charge. Meanwhile, the high-voltage current with the other polarity at the high-voltage output end of the high-voltage electrostatic generator is conducted to the non-direct contact ionization grounding electrode through a high-voltage resistant wire, because the discharge end of the electrode is made of hundreds of fine carbon fiber wires, the tips of the numerous carbon fiber wires are exposed in the air, the high-voltage electrostatic current input by the high-voltage electrostatic generator continuously discharges the air to ionize the air, and therefore the electrostatic charge with one polarity can be effectively conducted to a target object through the air, and the target object can smoothly carry the electrostatic charge with the other polarity. Meanwhile, the grounding electrode is arranged near the hand gripping position of the spray gun grip, although the grounding electrode is not directly contacted with the epidermis of the limbs of the human body, the static charges emitted by the electrode are easily and indirectly conducted to the epidermis of the human body and the limbs through the air due to the close distance, and the static charges can be conducted to a target object through the human body conduction grounding way, so that the target object is charged with the static charges, and the reliability and the stability of the high-voltage static grounding are effectively improved.

In summary, the following steps: when the charged fog drops with one polarity sprayed from the water pump through the nozzle are deposited near the target under the multiple actions of external force pushing, earth attraction and electric field force, the target is effectively charged with the other polarity due to the double conduction of air ionization conduction and human body non-contact conduction of the non-direct contact type ionization grounding electrode. Therefore, when the dynamic charged droplets with one polarity static charge are settled to be close to the static target object with the other polarity static charge, the dynamic charged droplets can quickly run to the static charged target object under the mutual attraction of the opposite charges, so that the dynamic charged droplets can be firmly adsorbed on the upper side, the lower side, the left side and the right side of the target object, and a good surrounding adsorption effect is formed.

The hand-held electric electrostatic spray gun of the invention adopts a non-metal charging electrode and a double non-direct contact grounding current closed loop, changes the prior method that a direct liquid contact charging electrode made of metal materials such as copper and the like is adopted and the human epidermis is directly contacted to conduct high-voltage static electricity to be grounded, and creatively adopts a non-metal corrosion-resistant carbon fiber wire electrode and a double non-human direct contact grounding method to conduct static electricity to a target object to form a complete current closed loop, thereby not only ensuring the realization of good surrounding adsorption effect of electrostatic spray, but also ensuring the personal safety and comfortable sensation of an operator, and further eliminating a plurality of defects in the prior art.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the inventive concept of the present invention, and these changes and modifications are all within the scope of the present invention.
