Description

Disinfectant Dispenser {DEVICE FOR SPRAYING ANTISEPTIC SOLUTION}

The present invention relates to a disinfectant spray device, and more particularly, disinfectant solution is quickly cut off, the rotation speed of the drive motor is not required, the injection speed is increased, the structure is improved to reduce the manufacturing cost and power consumption It relates to a disinfectant spray device.

In general, the disinfectant spray device has a container containing a chemical in a liquid state and a sensor to be configured to automatically spray the material in the container, which requires hand hygiene such as a hospital, a food factory, a restaurant, and a catering company. As a means to prevent diseases and transmission caused by all pathogens that can be generated from the hand in the place, it is a device for disinfecting and cleaning the germs on the hand by using disinfectant and disinfection gel before entering work.

Such disinfectant spraying apparatuses include manual and automatic electric spraying using push buttons.

Among these, the manual type using the electronic push button, the price is low, but the disinfectant solution may be abused, there is a problem and inconvenience of re-contamination because you have to press the injection handle.

The latter automatic electric spraying method includes a sensing sensor and an electric spraying device, which detects an object and automatically sprays the pump. There are a pumping type, a solenoid valve type, and an actuator type using a mechanical pump.

Among these, the pumping type is required to include a motor pump pressurizing device and a solenoid valve, so the manufacturing cost is high, and miniaturization is difficult. And since the injection amount must be adjusted by the drive time of the solenoid valve, the injection amount display unit and the injection control device should be provided. These factors contribute to an increase in manufacturing costs.

In particular, since the main body of the sterilizer, the disinfectant container, the injection pump, and the spray nozzle are fixedly connected through the pipe, there is a considerable inconvenience in the cleaning management such as regular cleaning and replacement of the disinfectant container, the spray pump and the spray nozzle.

Since the solenoid valve type without the pressurization device is used with butane gas as a solvent, there is always a risk of explosion, but since butane gas is harmless to human body but chemically processed, there is a possibility of side effects. It is not suitable as a hand disinfectant to be used in the edible treatment of, and there is a problem that various disinfectants cannot be used because it is mixed with butane gas.

In addition, the actuator type, which is widely used in shampoo containers and dishwashing containers, and uses low-cost mechanical pumps, presses the pump by changing the rotational force of the motor into linear motion. As the motor continues to rotate for a certain time, it is difficult to control the injection amount, and even after the injection is completed, it is difficult to quickly return the disinfectant solution.

On the other hand, Korean Patent Publication No. 2001-28909 (2001.04.06) discloses a hand sterilizer. This hand sterilizer is a method of spraying disinfectant solution by changing the rotational movement into a linear motion with a fan-shaped gear, and it does not return quickly to the origin after spraying due to the characteristic of a fan-shaped gear that rotates only a certain angle without rotating 360 degrees. The reason is that the reverse rotation must be applied to the motor in order to return quickly, because the inertia force of the motor does not cause the reverse rotation.

As a result, the discharging of disinfectant solution is not cut off quickly, and a leak occurs. It is difficult to control the precise injection amount of the disinfectant solution due to the rotational inertia of the motor, and the motor must be rotated in order to return to the origin. The manufacturing cost is increased because the circuit must be used.

In addition, since the sterilizer main body and the disinfectant container are fixedly connected through the pipe, it is inconvenient to manage the cleaning and replacement of the container regularly, and it is difficult to miniaturize the product because the used actuator structure is vertical.

In addition, Korean Patent Utility Model Publication No. 20-0440156 (2008.05.21) discloses a disinfectant spraying device. This disinfectant spraying device is sprayed by pushing the bottom of the container with a fan-shaped gear, which is also not rotated 360 degrees but due to the characteristic of the fan-shaped gear that rotates only a certain angle. The discharge is not cut off quickly and leakage occurs.

In addition, the disinfectant solution injection device is difficult to control the injection amount of the disinfectant solution due to the rotational inertia of the motor, it is difficult to miniaturize the product because the gear assembly structure of the used actuator is a vertical structure.

The present invention was created in order to solve the above problems, by using a cam that rotates the rotational movement in the vertical motion to rotate 360 degrees to prevent the leakage of the disinfectant sprayed quickly to prevent leakage, manufacturing costs And to reduce the power consumption, and to provide a disinfectant spray device that enables the miniaturization of the product.

At this time, the actuator device, a drive motor installed in the main body for driving the pump; A gear train installed to transmit the rotational motion of the drive motor to increase rotational torque; It characterized in that it comprises a; cam device provided to pressurize the pump by converting the rotational movement of the gear train to vertical movement in the vertical direction.

According to the embodiment of the present invention, by applying a cam gear using actuator device without using a conventional fan-shaped gear, it is possible to quickly block the disinfectant solution can be prevented leaking.

In addition, since the driving motor is not required to rotate in reverse, the injection speed is increased, and thus, an electronic circuit device is not required to be installed, thereby reducing manufacturing costs and reducing power consumption.

In addition, the gear assembly structure of the used actuator device can be made horizontal, which makes it possible to miniaturize the product.

And since the injection amount adjusting knob is installed, there is no need for an electrical control device and an injection setting display device for adjusting the injection amount, it is possible to further reduce manufacturing costs.
