Description

Automatic antibacterial sprayer

This creation relates to an automatic bacteriostatic sprayer, especially a new portable disinfection sprayer capable of spraying disinfection mist and steam with a powerful electric power with a single hand, making the spray disinfection efficiency more detailed than the conventional sprayer, and the use and carrying Facilitate the increase of structural technicians who demonstrate the effectiveness of disinfection.

The prior art disinfection sprayers can be used for spraying effects, but there is a gap between the degree of meticulousness and the convenience of use, resulting in a poor effectiveness of the disinfection solution.

Aside from spray trucks that are convenient for personal use, the disinfection sprayers currently used by individuals are purely relying on manual force to actuate mechanical levers to pressurize pumping structures. For example, the disinfectant bucket is behind and the bucket is facing up. The sprayer with a squeeze lever protruding from the front and bottom, although the user can reach out and pull back the squeeze lever every time, he can squeeze a lot of disinfectant mist vapor from the vat behind him and spray it forward, making the lanes slightly more spacious. The area can be adequately sprayed, but it is very inconvenient to carry a heavy disinfectant bucket. If it is not necessary to spray for a long distance, only the corners of the house where cats and dogs have remnants need to be cleaned and disinfected. Some people want to carry this equipment in trouble, just to do the spray disinfection, and its spray performance is difficult to control the small amount of detailed spraying in a narrow place, and users frequently reach down and squeeze back The movement of pressing the pull rod is very large. After a period of time, the arm muscles are often sore because of the hands being raised too often and too often. The spray volume will also be difficult to be consistent with the user's grip and pull strength. In addition, people also use a single-handed spray bottle that can be used for watering flowers. The bottle is converted into a disinfectant solution for environmental spray disinfection. Although the bottle can carefully sterilize a small amount of sprays and sprays in small places, it is convenient to carry, but the spraying distance is short, which is almost only suitable for the function of spraying flowers or cleaning hands with a short distance. For large indoor environments or Larger semi-open or open spaces, such as the corners of the house, highlight that the spraying efficiency is not high. It is necessary to spray multiple times without a slight breeze blowing to accumulate the disinfection spray effect on the spray area. From this, it can be seen that the previous various disinfection sprayers Although both can be used for spray effects, there is a gap between the degree of meticulousness and the convenience of use. It is difficult to achieve both meticulous spraying and convenient use, resulting in poor effectiveness of the disinfectant.

In view of the fact that the sterilization of the conventional disinfection sprayer cannot be combined with the convenience of use, resulting in the lack of various disinfection effects, the author actively conceived the solution. After repeated experimental discussions, this creation finally came into being.

Therefore, this creation provides an automatic bacteriostatic sprayer, which is different from the sprayer that is convenient for individuals to use purely manual force to actuate mechanical lever pressure pumps for disinfection and spraying. It can be operated with a single hand to control the powerful spraying of disinfection mist vapor. It consists of a casing and a spray tube in the casing, a blower motor, a liquid supply bottle, a driving circuit, a battery pack, and a push switch that is partially exposed. The casing includes a female casing and A pull-out type sub-shell plate, a grip hole is recessed at one end of the female shell, and the other end of the grip hole is recessed at the other end of the socket, and a penetrating opening of the spray nozzle of the collet is provided, and a nozzle structure is provided at the spray end of the spray pipe The other end of the spray tube is connected to the air outlet tube of the blower motor, which is restored to the middle part of the spray tube and hangs down from the vertical connection tube of the top ring of the liquid supply bottle. The inner surface of the plate is fixed to the bottom of the liquid supply bottle. Between the embedded sealing edge of the sub-shell plate cover, a corresponding spring clip hook mechanism is provided to enable the pull-out sub-shell plate to carry the liquid supply bottle cap back to the sealed mother housing, and the blower motor is electrically driven to drive The circuit is connected to the battery pack, and the controlled point of the driving circuit is electrically connected to the electrical contact of the push switch, so that the pressing end of the push switch floats out of the female casing, so that the liquid supply bottle is taken out, the disinfectant is filled, and the liquid supply bottle is put back In the lifting, the fingers can be pressed to press the switch's pressing end, and strong spray power can be sprayed and disinfected, making the spray disinfection efficiency more detailed than the conventional sprayer, and more convenient to use, and highlighting the disinfection effect. After countless studies, the design The inhalation is achieved and the mist is introduced into the mist tube. The thin fiber can save water, and it can achieve about 50 square meters per minute. It is so efficient. Even if there is a breeze blowing slowly in the semi-open or open space, it will not cause too much spray effect. Great influence, this is the main purpose of the creation.

In addition, in this creation of this automatic antibacterial sprayer, the bottom of the liquid supply bottle is a pull-out type sub-shell plate, and the clip-type hook design is used to cover the mother housing, which is convenient for replacing and fixing the liquid supply bottle and the female housing. The clip hook mechanism between the edge of the removable sub-shell plate and the hook can be fixed with a hand pull to remove the bottle, so that the liquid replenishment action is like a gun magazine, which can easily advance and remove the liquid supply bottle. Filling the disinfectant solution or quickly changing another bottle for the liquid supply bottle, and then continuing the disinfection work quickly, this is another purpose of the creation.

Furthermore, in this creation of this automatic bacteriostatic sprayer, under the use function and taking into account the smooth flow of the airflow, at least one side of the female shell forms an air inlet baffle in a circular plate, and the female shell is at the air inlet The outer edge of the baffle is formed with a circular arc-shaped through hole with a constricted ring lip. An annular gap between the constricted ring lip and the baffle edge of the air inlet port forms an expanded air intake that provides a source of air for the blower motor. Therefore, the shape of the circular expanded air inlet prevents the air from being blocked, and allows the air to flow into the shell around the four sides, so that the overall air intake is durable and normal.

In addition, in this creation, the automatic bacteriostatic sprayer has a grip recessed at one end of the female casing. The hole shape is arc-shaped design, the palm decompression ratio can be designed to withstand the pressure of lifting for 30 minutes, and the entire shape is about the size of a normal bento box, which is convenient to hold and relax. This is another purpose of this creation. .

Furthermore, this automatic bacteriostatic sprayer of this creation, the nozzle structure of the spraying tube of the spraying tube is also covered by a tube end sleeve with an outer ring fin wheel, a wheel back ring plate, and then stacked on the wheel back ring plate. It is connected to the other end of the outer ring fin wheel. It consists of a pipe end sleeve protruding from the screw lock and a pipe screw connection to a water pipe socket. The outer wall of the outer ring of the pipe end sleeve is covered and glued to the structure of the spray pipe connection nozzle. The nozzle is connected to the pipe end protruding from the center of the water pipe socket. The nozzle of the pipe is usually made by the spray pipe industry. The outer ring fin wheel has a fin height of 3-4mm. The height of the end sleeve is 3-4cm, and the height is only 3-4cm shallow, so that the outer wall of the outermost ring of the tube end sleeve cannot be completely covered and fixed to the nozzle of the nozzle structure. Highly relying on hand pressure to push the pump. Suction and liquid atomization of the pump is still acceptable, but this creation is improved by relying on electric air pumps for air suction and atomization. Such a shallow socket depth cannot support the electric drum pump. Pneumatic pressure will cause pressure separation and damage, so the spray tube made by this automatic bacteriostatic sprayer Further, both the fins of the outer ring fins and the tube end sleeve are increased, the fin height of the outer ring fin wheel is increased to 1.2 cm, and the height of the tube end sleeve is increased to 1.8 cm, so that The sleeve's cementation depth is increased, it can withstand the high-pressure jet required for this creation, complete more effective diversion, improve the atomization and ejection ability, and add the outlet pipe of the blower motor to contact the inside of the spray pipe air duct, and design a thicker diversion. The interface makes the joint end more stable and difficult to deform and displace, which can be more closely connected with the air flow and water to form a denser force, allowing water and gas to gather more force, and reach a distance of 2 meters, which is a further step in this creation. purpose.
