Description

Hand sterilizer

The present invention relates to a hand sterilizer, and specifically, to a hand sterilizer capable of measuring body temperature and spraying a disinfectant according to recognition of the hand through one sensor.

Recently, as a countermeasure against various infectious diseases, it is recommended to wash your hands frequently or disinfect your hands with hand sanitizers.

In particular, there is a high possibility that a disease or virus is transmitted in a place where people are frequently accessed or in a place where people are gathered (for example, indoor spaces). Therefore, a hand sterilizer to which the disinfectant is automatically sprayed is disposed at the entrance of the indoor space for user convenience.

In general, a hand sterilizer disposed at the entrance of an indoor space is formed to recognize the user's hand and spray the disinfectant toward the user's hand when the user's hand is placed in a space where the disinfectant is sprayed. In this case, the user's hand is generally recognized by a distance sensor provided in the hand sterilizer.

On the other hand, in order to prevent infectious diseases, it is necessary to measure the body temperature of a person suspected of having a disease, and the body temperature of the person is measured through a device such as a thermometer or thermal imaging camera separately provided with a hand sterilizer.

If a person's body temperature is measured through a device such as a thermometer or a thermal imaging camera, and the hand is disinfected with a hand sterilizer, procedural hassle may arise, and space restrictions for placing the device may occur. There is a problem that can increase the installation cost of the.

For example, Patent Publication No. 10-1112125 discloses a conventional visitor body temperature measuring device.

The present invention has been made to solve the above-described problem, and an object of the present invention is to provide a hand sterilizer capable of injecting a disinfectant into the user's hand while measuring the user's body temperature through a single sensor provided in the hand sterilizer. .

In addition, an object of the present invention is to provide a hand sterilizer capable of minimizing manufacturing cost.

According to the present invention, while the body temperature of the user is measured by one infrared sensor, it may be determined whether or not the user's hand is located in the spray space.

When the converted body temperature exceeds a preset minimum temperature, the controller displays the body temperature on the display and simultaneously sprays the disinfectant through the spray module.

That is, according to the present invention, when the value measured by the infrared sensor exceeds a predetermined value, it is determined that the user's hand is located in the spray space, and the display and the spray module can be operated.

An injection nozzle may be provided at an end of the injection module, and the infrared sensor may be disposed to be spaced apart from the front of the case at a predetermined interval based on the injection nozzle.

This is to allow the light irradiated from the infrared sensor to be irradiated toward the user's wrist, so that the user's body temperature can be more accurately measured.

When the converted body temperature is below the minimum temperature, the control unit may repeatedly receive a signal from the infrared sensor until it exceeds the minimum temperature, but may stop the operation of the injection module.

This is to determine when the user's hand is not located in the injection space, and to prevent unnecessary operation of the injection module.

The body temperature converted by the control unit may be changed based on the temperature of the space in which the hand sterilizer is installed.

This is to compensate for the change of the value measured by the infrared sensor when the temperature of the space in which the hand sterilizer is installed is too high to exceed a certain range or too low to be less than a certain range.

1 is a side cross-sectional view schematically showing the appearance of a hand sterilizer according to an embodiment of the present invention.

1, a hand sterilizer 100 according to an embodiment of the present invention may include a case 110, an infrared sensor 120, an injection module 130, a display 140, and a control unit (not shown). have.

The case 110 may form the entire exterior of the hand sterilizer 100. A disinfectant spray space S may be provided in the case 110. For example, when the hand sterilizer 100 is viewed from the front, the disinfectant spraying space S may be formed to be concave toward the rear of the hand sterilizer 100. That is, the disinfectant spraying space S may be formed in a form in which the front surface is open. The user's hand may enter the disinfectant spray space S through the open front surface of the disinfectant spray space S.

In the disinfectant spray space S, the disinfectant is sprayed toward the user's hand 1, and the user's body temperature may be measured.

The infrared sensor 120 may be provided in the case 110. For example, the infrared sensor 120 may be installed on the upper surface 111 that partitions the disinfectant spray space S in the case 110. The infrared sensor 120 may be formed to irradiate infrared light toward the wrist 2 of the user introduced into the disinfectant spray space S and receive the reflected infrared light.

Infrared light is irradiated toward the user's wrist 2 by the infrared sensor 120, and light reflected from the user's wrist is collected by the infrared sensor 120, so that the user's body temperature may be measured.

Since a number of the principles of the non-contact infrared thermometer are already known, detailed descriptions thereof will be omitted.

The spray module 130 may be provided in the case 110 and may be formed to spray a disinfectant toward the disinfectant spray space S. For example, a spray nozzle 131 may be provided at an end of the spray module 130. The spray nozzle 131 may be installed on an upper surface 111 that partitions the disinfectant spray space S in the case 110. The disinfectant may be sprayed downward toward the disinfectant spray space S through the spray nozzle 131.

In addition, the injection module 130 may be disposed to be spaced apart from the infrared sensor 120. Specifically, the injection module 130 may be disposed closer to the rear end of the case 110 compared to the infrared sensor 120. In other words, the infrared sensor 120 may be disposed to be spaced from the front of the case 110 at a predetermined interval based on the injection nozzle 131. That is, the infrared sensor 120 may be disposed closer to the rear end of the case 110 than the spray nozzle 131.

At this time, the preset interval corresponding to the distance between the infrared sensor 120 and the injection nozzle 131 is, when the injection nozzle 131 faces the user's hand 1, the infrared sensor 120 May be determined as a suitable distance to face the user's wrist 2.

Therefore, when the user's hand is introduced into the injection space S, after the user's body temperature is measured by the infrared sensor 120, the disinfectant may be sprayed onto the user's hand by the injection nozzle 131. .

For example, the preset interval may be determined through an experiment, and may be set to different distances in the hand sterilizer for adults and the hand sterilizer for children.

The control unit is connected to the infrared sensor 120 and may be formed to convert a value measured by the infrared sensor 120 into body temperature. That is, the control unit may be formed to process a value (raw data) sensed by the infrared sensor 120 and convert it into a user's body temperature. The method of processing the value (raw data) sensed by the infrared sensor 120 can be derived in various ways through experiments, and since a number of non-contact thermometers that measure body temperature by an infrared sensor are already known, a detailed description thereof Is omitted.

The display 140 may be provided in the case 110 and may be formed to display the body temperature of the user converted by the control unit. For example, while displaying the user's body temperature on the display 140, a state such as "normal" or "abnormal" may be displayed. "Normal" and "abnormal" may be determined according to whether the user's body temperature is within a preset range.

The hand sterilizer 100 according to an embodiment of the present invention may further include a QR code recognition unit 150 capable of recognizing a previously issued QR code of a user. The user's QR code may include user information (eg, name, age, contact information, address, etc.). The user's QR code can be issued through government offices such as city hall and ward office.

After the QR code of the user is recognized by the QR code recognition unit 150, the infrared sensor 120, the injection module 130, and the display 140 may be operated. This is to facilitate tracking of users with abnormal symptoms while grasping visitor information.

Hereinafter, a connection relationship and control of main components of a hand sterilizer according to an embodiment of the present invention will be described with further reference to other drawings.

2 is a diagram illustrating a connection relationship between main components of a hand sterilizer according to an embodiment of the present invention.

2, the hand sterilizer 100 according to an embodiment of the present invention may further include a speaker 160 and a communication module 170 for communicating with an external server 180 in addition to the above-described configurations. have.

For example, the speaker 160 may be formed to transmit information such as a user's body temperature and whether an infectious disease or disease is suspected based on the body temperature by voice. In addition, various information including the user's body temperature and abnormality may be transmitted to the external server 180 through the communication module 170.

The control unit C may be formed to control the infrared sensor 120, the injection module 130, the display 140, the QR code recognition unit 150, the speaker 160, and the communication module 170. That is, the control unit C may be electrically connected to the infrared sensor 120, the injection module 130, the display 140, the QR code recognition unit 150, the speaker 160, and the communication module 170.

Hereinafter, control of the main components by the controller C will be described.

The infrared sensor 120 may be formed to measure the user's body temperature by irradiating infrared light onto the wrist of the user entering the above-described spray space S.

The controller C may determine whether the user's hand is positioned in the spray space S based on the value measured by the infrared sensor 120. That is, when the value measured by the infrared sensor 120 is transmitted to the control unit C, the control unit C determines whether the user's hand is located in the injection space S, and the injection module 130 You can decide whether to work or not.

Specifically, when the user's body temperature based on the value measured by the infrared sensor 120 exceeds a preset minimum temperature (eg, 30° C.), the control unit C It can be determined that the hand is located.

At this time, the control unit C may operate the injection module 130 so that the disinfectant is sprayed toward the user's hand. The injection module 130 may be controlled by the control unit C so that a predetermined amount of disinfectant is injected during one operation.

In contrast, if the user's body temperature based on the value measured by the infrared sensor 120 is less than the minimum temperature, the controller C may determine that the user's hand is not located in the spray space S. This is, when the user's hand is not located in the injection space (S), the temperature based on the value measured by the infrared sensor 120 is the temperature of the injection space (S) lower than the body temperature of the user or of the case 110 Because it is temperature.

At this time, the control unit C may maintain the operation of the injection module 130 in a stopped state so that the disinfectant is not injected.

In addition, when the user's body temperature is below the minimum temperature, the controller C may repeatedly receive the signal from the infrared sensor 120 until the minimum temperature is exceeded. Even at this time, the control unit C may stop the operation of the injection module 130.

The minimum temperature may be determined through an experiment, and the above-described 30°C is only an example of the minimum temperature, and the minimum temperature is not limited to 30°C.

The injection module 130 may include a nozzle 131, a disinfectant storage tank 133 and a pump 139.

The nozzle 131 is provided at an end of the injection module 130 and may be disposed to face the injection space S. Accordingly, the disinfectant may be sprayed into the spray space S through the nozzle 131.

The nozzle 131 may be connected to the pump 139 through a first passage 135, and a first valve 136 may be provided in the first passage 135. When the first valve 136 is opened while the pump 139 is driven by the control unit C, the inside of the first flow path 135 may be pressurized by the pump 139.

The disinfectant storage tank 133 formed to store the disinfectant may be connected to the first passage 135 through a second passage 137, and a second valve 138 may be provided in the second passage 137. have. The second flow path 137 may be connected to the first flow path 135 between the nozzle 131 and the first valve 136.

When the first valve 136 is opened by the control unit C, the second valve 138 may also be opened at the same time. In this case, the disinfectant stored in the disinfectant tank 133 may be guided to the nozzle 131 by sequentially passing through the second passage 137 and the first passage 135.

The controller C may control the display 140 to display the user's body temperature determined based on a value measured by the infrared sensor 120. For example, the value measured by the infrared sensor 120 may be converted to a temperature (ie, the user's body temperature) by the controller C, and the user's body temperature converted by the controller C is displayed in the display. It may be indicated at 140. In addition, the display 140 may display a state such as "normal" or "abnormal" depending on whether the user's body temperature is within a preset range.

The control unit (C) displays the body temperature on the display 140 and simultaneously activates the injection module 130 only when the user's body temperature based on the value measured by the infrared sensor 120 exceeds the minimum temperature. Disinfectant can be sprayed through.

Accordingly, when using the hand sterilizer 100, the user can easily grasp his/her body temperature and abnormality through the display 140 and receive a disinfectant.

On the other hand, there is a problem in that the body temperature of the user determined by the controller C may vary based on a value measured by the infrared sensor 120 according to the temperature of the space in which the hand sterilizer 100 is installed.

The body temperature converted or determined by the controller C based on the value measured by the infrared sensor 120 may be changed based on the temperature of the space in which the hand sterilizer 100 is installed. Although not shown, a temperature sensor for sensing a temperature of a space in which the hand sterilizer 100 is installed may be provided in the case 110.

For example, if the temperature of the space in which the hand sterilizer 100 is installed is within a normal range (for example, 20°C to 30°C), the control unit is based on the value measured by the infrared sensor 120 ( The body temperature converted in C) may not change.

In contrast, when the temperature of the space in which the hand sterilizer 100 is installed exceeds the normal range, the control unit C is a negative value preset to the body temperature converted based on the value measured by the infrared sensor 120 Can compensate.

In addition, when the temperature of the space where the hand sterilizer 100 is installed is less than the normal range, the control unit C compensates a preset positive value to the body temperature converted based on the value measured by the infrared sensor 120 can do.

In addition, the body temperature compensated in this way is displayed on the display 140, and whether "normal" or "abnormal" may be determined by the controller C based on the compensated body temperature. The preset positive value and the preset negative value may be determined through an experiment.

Therefore, according to the present invention, even when the temperature of the space where the hand sterilizer is installed is too high or too low to affect the value measured by the infrared sensor 120, the user's body temperature can be determined more accurately. .

The control unit C controls the QR code recognition unit 150 and may receive user information recognized by the QR code recognition unit 150. In this case, the information may be transmitted to the external server 180 through the communication module 170. The server 180 may be an administrator server.

Information transmitted to the server 180 through the communication module 170 includes the user's body temperature, whether it is "normal" or "abnormal", the user's name, address, and contact information, as well as a motor provided in the pump 139 (not It may further include information on the remaining amount of the disinfectant based on the temperature of (city) and a water level sensor (not shown) provided in the disinfectant storage tank 133.

Accordingly, the administrator, through the information transmitted to the server 180, not only information on the user, but also whether the pump 139 provided in the hand sterilizer 100 is abnormal, and the remaining amount of the disinfectant contained in the disinfectant storage tank 133. By easily grasping about, maintenance of the hand sterilizer 100 can be easily performed.

On the other hand, the control unit (C) after the user QR code including the user's information is recognized by the QR code recognition unit 150, the infrared sensor 120, the injection module 130 and the display 140 Can work. That is, after a user's QR code is normally recognized by the QR code recognition unit 150, other components of the hand sterilizer 100 may be operated normally.

Accordingly, according to the present invention, it is possible to collect all information on a user visiting a specific place where the hand sterilizer 100 is installed.

Finally, the controller C may control the speaker 160 provided in the case 110 described above. The speaker 160 may be formed to deliver information displayed on the display 140 to a user through voice or an alarm.

For example, information on the user's body temperature displayed on the display 140 and whether it is "normal" or abnormal" may be provided to the user through the speaker 160.

In addition, when the user's body temperature is not accurately measured due to an incorrect position of the user's hand or wrist (for example, when the temperature measured through the infrared sensor 120 is below the aforementioned minimum temperature), the control unit C May request the user through the speaker 160 to correct the position of the user's hand or wrist.

Specifically, after the user QR code is normally recognized by the QR code recognition unit 150, the temperature repeatedly measured through the infrared sensor 120 for a preset time (eg, 10 seconds) is the minimum temperature. Below, the user's wrist may not face the infrared sensor 120.

In this case, the speaker 160 may be controlled by the controller C such that a voice for correcting the position of the user's hand or wrist is generated through the speaker 160.

As described above, according to the present invention, the user's body temperature can be more accurately measured by accurately irradiating the user's wrist with infrared light.

Hereinafter, a control method of a hand sterilizer according to an embodiment of the present invention will be described with reference to other drawings.

3 is a first flow chart showing a control method of a hand sterilizer according to an embodiment of the present invention. Specifically, FIG. 3 is a flow chart for explaining the hand disinfection process (S20, see FIG. 4) of the hand sterilizer. It is obvious that the description of the components of the hand sterilizer 100 may be equally applied to the control method of the hand sterilizer 100.

3, the control method of the hand sterilizer includes an infrared sensor driving step (S210), a body temperature (T _b ) measuring step (S220), a body temperature determining step (S230), a display and storage step (S240), and a disinfectant spraying step ( S250) may be included.

In the infrared sensor driving step (S210), the infrared sensor is driven. At this time, when the hand sterilizer 100 is normally operated, the infrared sensor may be continuously driven in the infrared sensor driving step S210.

In the body temperature (T _b ) measuring step (S220), the body temperature of the user may be measured by the above-described control unit. The user's body temperature may be measured by the control unit based on a value sensed through the infrared sensor.

In the body temperature (T _b ) measuring step (S220), a positive value or a negative value may be compensated for the temperature (body temperature) measured by the control unit based on the temperature of the space in which the hand sterilizer is installed. Since this has been described above, a detailed description thereof will be omitted.

In the body temperature determination step S230, it may be determined whether the body temperature measured by the control unit is accurately measured through the user's wrist. That is, in the body temperature determination step S230, it may be determined whether the user's hand is accurately positioned in the spray space of the hand sterilizer (that is, whether the user's wrist is positioned to correspond to the infrared sensor).

Specifically, in the body temperature determination step (S230), when the body temperature measured by the control unit exceeds a preset minimum temperature (eg, 30°C), it is determined that the user's hand is accurately positioned within the spray space of the hand sterilizer. Can be. In contrast, in the body temperature determination step (S230), if the body temperature measured by the control unit is below a preset minimum temperature, it is determined that the user's hand is not introduced into the injection space of the hand sterilizer, or that the user's hand is not accurately positioned even if it is introduced. Can be.

If the body temperature measured by the control unit in the body temperature determination step (S230) is less than a preset minimum temperature, the infrared sensor driving step (S210), the body temperature (T _b ) measuring step (S220) and the body temperature determining step (S230) are repeated. Is done with

When the body temperature measured by the control unit in the body temperature determination step S230 exceeds a preset minimum temperature, information about the user's body temperature may be displayed on the display in the display and storage step S240. In the display and storage step (S240), information about the user's body temperature may be stored in a memory inside the hand sterilizer or in an external server communicating with the hand sterilizer.

Finally, in the disinfectant spraying step 250, the disinfectant may be sprayed toward the user's hand located in the spray space through the spray module.

As described above, according to the present invention, without a configuration such as a distance sensor or a thermal image sensor, the user's body temperature can be determined with only one infrared sensor, and at the same time, whether or not the user's hand is located in the spray space can be determined.

Hereinafter, a method of controlling the hand sterilizer will be further described with reference to other drawings.

4 is a second flow chart showing a control method of a hand sterilizer according to an embodiment of the present invention.

Referring to FIG. 4, the control method of the hand sterilizer according to the present invention further includes a user information grasping step (S10) for grasping user information prior to the hand sterilization process (S20) of FIG. 3 described above.

In the user information grasping step (S10), as the user QR code is recognized by the QR code recognition unit provided in the hand sterilizer, the user information may be recognized. After the user information is normally recognized in the user information grasping step S10, the hand sterilization process S20 may proceed.

In addition, according to the present invention, after the hand sterilization process (S20), the hand sterilizer abnormality determination step (S30) and the information transfer step (S40) may be further included.

In the hand sterilizer abnormality determination step (S30), it is determined whether the motor is abnormal based on the temperature of the motor provided in the above-described pump, and accommodated in the disinfectant storage tank based on the value measured by the water level sensor provided in the disinfectant storage tank. The remaining amount of disinfectant can be determined.

Here, when the temperature of the motor exceeds a preset normal temperature range, it may be determined that an abnormality has occurred in the motor (or pump). In addition, if the value measured by the water level sensor is less than or equal to a preset water level, it may be determined that it is necessary to replenish the disinfectant in the disinfectant storage tank.

When no abnormality is found in the hand sterilizer abnormality determination step (S30), the user information grasping step (S10) and the hand sanitization procedure (S20) may be repeatedly performed.

In contrast, when an abnormality is found in the hand sterilizer abnormality determination step (S30), specific information related to the abnormality (eg, an abnormality in the motor or insufficient disinfectant, etc.) may be stored in a memory in the hand sterilizer or in an external server. .

Accordingly, the administrator can quickly and easily maintain the hand sterilizer based on the information determined and transmitted in the hand sterilizer abnormality determination step (S30).
