The present invention relates to a sterilizer, and more particularly, to a vehicle disinfecting sterilizer to spray the disinfectant solution in a high particle state, such as indoors or mats of the vehicle.

In general, to wash a car, a self-cleaning car wash or a gas station washes a lot. The car wash is also equipped with a mat washer or vacuum cleaner, so that the user can conveniently wash the seat or mat inside the car.

However, cleaning or washing with a mat washer or vacuum cleaner has limitations in removing germs such as molds, and the mats and seat seats still propagate germs.

In order to remove odors and bacteria in the vehicle interior, some drivers spray disinfection using a disinfectant sprayer, etc., but in this case, since the user manually sprays, it is never easy to disinfect and thoroughly disinfect the vehicle interior.

Accordingly, there was a demand for a sterilizer capable of easily disinfecting the interior of a vehicle. As an example of the solution, there is a “internal disinfector using a nano silver” of Utility Model Registration No. 373680.

Utility Model Registration No. 373680, “In-vehicle Sterilizer Using Nano Silver,” in which nano-silver colloidal solution and compressed air were introduced into the spray gun through each electronic switch and each hose and mixed and injected through the spray gun It is starting.

However, Utility Model Registration No. 373680 as described above does not properly disinfect because the injection particles of the disinfectant solution due to the mixing of air and the solution is poorly penetrated into the sheet or mat, and thus its efficiency is low. In addition, each of the hoses connected to transport the compressed air and the disinfectant solution is coupled to the spray gun, the structure is complicated, and there is also inconvenience in use. Moreover, as the air compressor is installed for air compression, the sterilizer itself has a large volume and operation noise.

Accordingly, it is an object of the present invention to provide a vehicle disinfectant for disinfecting the vehicle to evenly penetrate the sheet or mat in the vehicle to increase the efficiency of disinfection even in a small amount.

In accordance with the above object, the present invention, in the vehicle sterilizer, the pressure pump is installed in the outlet of the disinfectant storage tank installed in the main body, the pressurized check valve coupled to the spray gun and the self-opening pressure adjustable through the connection hose It is configured to be connected to the pump, wherein the pressure pump pumps the disinfectant solution at a first pressure and the check valve is opened as the second pressure higher than the first pressure is applied through the connection hose to the injection gun It characterized in that it is configured to be sprayed disinfectant solution in a high particle state.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the same elements in the figures are represented by the same numerals wherever possible. In addition, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

1 is an external perspective view of a vehicular injection sterilizer according to an embodiment of the present invention, Figure 2 is a side cross-sectional configuration of Figure 1 of the present invention, Figure 3 is a partial coupling cross-sectional view of the check valve shown in Figs. 4 is a circuit block diagram of a vehicular spray sterilizer according to an embodiment of the present invention.

Vehicle disinfecting sterilizer 100 according to an embodiment of the present invention, but the upper body 20 is assembled on the upper portion of the lower body 10 to configure the body portion, the user has a height enough to be convenient to use. It is desirable that the height is about the eye level of the user.

The lower body 10 is provided with a disinfectant solution storage tank 14 in which the disinfectant solution 13 is stored and a pressure pump 16 for pressurized pumping the disinfectant solution 13. The pressure pump 16 is mounted on the bottom surface of the disinfectant storage tank 14, and a filter 18 is installed at the outlet of the disinfectant storage tank 14. The disinfectant solution filtered through the filter 18 is introduced into the pressure pump 16. An example of the pressure pump 16 is an electronic pump, a gear pump and the like, and it is preferable to employ a small size pump.

A first connection hose 19 is connected to the outlet of the pressure pump 16, and the first connection hose 19 is connected to the upper body 20 through a connection pipe 17 formed through the disinfectant storage tank 14. To a hose reel 26 mounted therein. The hose reel 26 is a device portion capable of winding and unwinding a hose.

Since the lower body 4 and the disinfectant storage tank 14 and the connection pipe 17 in the lower body 4 are all configured to be integrated, the volume of the lower body 4 is reduced, and at the same time facilitates the production of the main body. In particular, the connection pipe 17 formed to penetrate the storage tank 14 can pass not only the connection hose 19 but also other wires, so that the connection hose 19 or other wiring is not unnecessarily exposed to the outside. Provide an advantage.

In Fig. 2, reference numeral “39” in the disinfectant storage tank 14 refers to a mouthpiece.

Float 39 is floated on the surface of the disinfectant solution stored in the storage tank 14, the upper part by operating the sensor (38 of Figs. 2 and 4) when the float 39 is lowered to the predetermined minimum water surface position Among the lamps 36a and 36b mounted on the outer surface of the main body 20, the red lamp 36a lights red. When the antiseptic solution is normally filled in the storage tank 14, the red lamp 36a is turned off by the sensor 38, and the green lamp 36b is turned on green.

On the other hand, the upper body 20 is configured, the front portion is provided with a coin inlet 35 and red and green lamps (36a, 36b) as shown in Figure 1, the injection gun used for the user ( 44) is installed.

The injection gun 44 is coupled to the check valve 42 that can be opened and closed according to an embodiment of the present invention, the end of the check valve 42 is wound around the hose reel 26 in the upper body 20 2 connection hose 24 is connected. The second connecting hose 24 is guided by the guide roller 27, and can be unwound from the hose reel 26 installed in the upper body 20 and extended for a user's convenience. In addition, when the second connection hose 24 is used by the user, the guide roller 27 may be guided and wound around the hose reel 26 again.

The hose reel 26 installed in the upper body 20 allows the hose to be unwound when the user pulls the second connecting hose 24 by force, so that the hoses released automatically or manually after use can be wound up. The device structure is preferably implemented. An example of a method for automatically winding again is a method of using a resilience force of the coil spring or a method of providing a separate hose winding motor.

Also, in the upper body 20, various circuit components including the heater control unit 30, the timer setting unit 32, and the control unit 40 are mounted above the hose reel 26, as shown in FIG. 2. . In addition, a heater 28 is provided on the side of the hose reel 26.

4 illustrates a circuit block configuration including various circuit components of FIG. 2.

The main controller 40 controls the overall operation of the vehicular injection sterilizer 100, and in particular, controls the operation of the pressure pump 16.

The heater controller 30 controls the temperature of the heater 28 under the control of the main controller 40. The temperature sensor 31 detects a temperature inside the upper body 20 and outputs the temperature to the main controller 40. The components of the heater control unit 30, the heater 28, and the temperature sensor 31 are mainly wound hoses of the hose reels 26 installed in the interior of the upper body 20 due to cold weather, such as winter, and the inside thereof. It is a means to prevent freezing of the disinfectant remaining in the system. The operation switch SW connected to the heater control unit 30 is an on / off switch. In the summer, the manager turns off the operation switch SW so that the operating power supplied to the heater control unit 30 is cut off.

The timer setting unit 32 provides the set timer value to the main control unit 40 when the administrator sets the operating time of the pressure pump 16, and the coin detecting unit 34 enters the coin through the coin inlet 35. If detected, it is output to the main control unit 40.

In an embodiment of the present invention, the disinfectant may be sprayed using only the disinfectant pumping pressure without using compressed air. For this purpose, the main control part 40 may be a disinfectant of the storage tank 14 at which the pressurized pump 16 is the first pressure. And a check valve 42 coupled to the injection gun 44 is configured to open as the second pressure higher than the first pressure is applied through the connection hoses 19 and 24. For example, the first pressure is about 3 kg / cm 2, and the second pressure is preferably about 5 kg / cm 2.

The pressure of about 5 kg / cm 2 in the spray gun 44 becomes a very high pressure. This high pressure spray enables fine particle spray and uniform diffusion spray through the fine nozzle hole of the spray gun 44. Granular spray disinfectant sprayed with fine particles (in micrometers to nm) and uniformly dispersed is able to capture and kill almost all of the bacteria inhabiting the mat.

Since the above-mentioned first and second pressures are examples of the present invention, the present invention is not limited thereto and may be variously changed without departing from the spirit of the present invention. Self-evident

The check valve 42 is a check valve capable of adjusting the self-opening and closing pressure, and has a configuration as shown in FIG. 3.

Referring to FIG. 3, the check valve 42 is clamped by an opening / closing pressure adjusting screw 50 protruding from the rear side of the spray gun 44 with a tangier spring 48 for opening and closing the ball 46 therein. It is internally compressed and compressed. The opening and closing pressure adjusting screw 50 may be adjusted within a predetermined pressure range relatively higher than the pressurization (first pressure) in the pressure pump 16, it is adjusted by the operator or the user.

The check valve 42 having the above structure prevents leakage or injection of the disinfectant solution through the injection gun 44 until the second pressure is set in advance, and opens the valve when the second pressure is reached. High pressure spraying is performed in the spray gun 44. Since the structure of the check valve 42 can cover a relatively wide disinfection area with only a small amount of disinfectant solution, the spray sterilizer according to the embodiment of the present invention can be used even if an expensive disinfectant solution.

Now, the operation according to the embodiment of the present invention will be described in detail based on the above configuration.

The user who tries to disinfect the car mat pulls out the second connection hose 24 to the position where the object to be disinfected, such as the vehicle mat, and then inputs coins through the coin inlet 35 of the vehicle injection sterilizer 100.

When a coin is input into the coin inlet 35, the coin detecting unit 34 detects this and informs the main control unit 40. Accordingly, the main controller 40 controls to operate the pressure pump 16. When the pressure pump 16 is pumped at the first pressure, the disinfectant stored in the storage tank 14 is pumped and thus flows into the pressure pump 16 through the filter 18. Thereafter, the pressure is discharged to the first connecting hose 19 at the rear end of the pump 16.

At this time, the check valve 42 coupled to the injection gun 44 is not opened and closed because the preset second pressure is not applied. Accordingly, the internal pressure of the first and second connection hoses 19 and 24 is a pressurized pump ( It is gradually increased by the pressure pump of 16). Therefore, when the internal pressure of the first and second connection hoses 19 and 24 increases to the second pressure, the check valve 42 eventually opens, and the first and second connection hoses 19 and 24 Pressurized disinfectant solution may be sprayed through the spray gun 44.

The spray gun 44 is preferably provided with a trigger, and when the user pulls the trigger of the spray gun 44, a high-level disinfectant solution is sprayed from the spray nozzles of the spray gun 44.

As the disinfectant solution is sprayed from the spray gun 44, the user can disinfect an object such as a mat desired by the user. The disinfectant sprayed from the spray gun 44 becomes fine particle spray and uniform diffuse spray to penetrate into the inside of the vehicle or the mat. This kills most of the bacteria that live in the interior of the vehicle or around the mat.

On the other hand, the main control unit 40 operates the pressure pump 16 by the timer value set by the timer setting unit 32. If the timer expires, the main control unit 40 stops the operation of the pressure pump 16, the operation of the vehicle injection sterilizer 100 is stopped.

When the pressure pump 16 is stopped, the internal pressure of the first and second connection hoses 19 and 24 drops, and when the internal pressure drops below the second pressure, the check valve 42 automatically It will be closed. That is, when the internal pressure of the first and second connection hoses 19 and 24 drops below the second pressure, the ball 40 closes the valve hole by being pushed by the elastic force of the tangential spring 48 of the check valve 42. Discarded. The automatic opening and closing operation of the check valve 42 prevents the disinfectant solution from leaking or being weakly sprayed through the spray gun 44 by the residual internal pressure, thereby reducing the waste of the disinfectant solution.

In the above description of the present invention, specific embodiments have been described, but various modifications can be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be defined by the equivalents of the claims and claims.

As described above, the present invention increases the efficiency of disinfection by spraying a disinfectant solution in a high particle state on the inside of a vehicle or a mat after washing, thereby reducing the waste of the sprayed disinfectant solution.
