Technical Field

The invention relates to the field of disinfection storage boxes, in particular to a sterilization control system of a disinfection storage box.

Background

The manual button of general adoption of current disinfection receiver disinfects, promptly, only disinfects after opening the UV bactericidal lamp switch, and the user is long when deciding to disinfect by oneself, then closes the bactericidal lamp. The manual control mode often lets the user forget to turn off the lamp after turning on the germicidal lamp, which not only consumes electricity, but also causes UV light to leak out when turning on the box cover again, and the safety is poor. And automatic sterilization's disinfection box is generally all opened the UV lamp automatically and once disinfects after covering the lid each time, then self-closing UV lamp again, and this mode can avoid forgetting the condition emergence of turning off the lamp, but because the sterilization time at every turn is longer, consequently has got and need wait for a long time after the thing and just can open the lid again, if not wait and directly open the lid when disinfecting, UV light also can spill. Especially for children, because the harm of ultraviolet light is not understood, the operation is often mistakenly carried out, so that the UV light leaks out, and certain potential safety hazards are caused.

Disclosure of Invention

In order to overcome the defects, the invention provides a sterilization control system of a sterilization storage box capable of reasonably controlling sterilization, the sterilization storage box comprises a box body 1 and an upper cover 2, a UV lamp sterilization component 3 is arranged in the box body 1, a first contact switch K1 is arranged between the box body 1 and the UV lamp sterilization component 3, a second contact switch K2 is arranged between the upper cover 2 and the UV lamp sterilization component 3, and a key switch K3 is further arranged on the box body 1 or the UV lamp sterilization component 3. The UV lamp sterilization component 3 comprises a battery, an MCU and a UV lamp, wherein the MCU and the UV lamp are powered by the battery, the MCU comprises a switch identification module, a time calculation control module, a UV lamp control module and a battery sampling control module,

the switch identification module is used for identifying the on/off of a first contact switch K1, a second contact switch K2 and a key switch K3 and transmitting the on/off state information of the three switches to the time calculation control module;

the time calculation control module is used for setting a long sterilization time t1, a bacteriostasis time t2 and a short sterilization time t3, taking the duration t as a working unit, taking the duration t as t1+ t2, receiving information sent by the switch identification module, entering a long sterilization mode of the working unit after receiving information that all three switches are closed for the first time, sending long sterilization information to the UV lamp control module, starting timing of the first working unit at the same time, sending bacteriostasis information to the UV lamp control module when the accumulated long sterilization time reaches t1, at the moment, the system enters the bacteriostasis mode, and simultaneously, when the accumulated bacteriostasis time reaches t2 (namely after the duration t of the working unit is accumulated to be full), the time calculation control module sends information for entering the low power consumption mode to the battery sampling control module, and at the moment, the system enters the low power consumption mode, in the mode, any switch is switched off and then is switched on, and the system enters a new working unit again;

the UV lamp control module is used for receiving the information sent by the time calculation control module, controlling the UV lamp to be turned on for t1 time when long sterilization information is received, controlling the UV lamp to be turned off for t2 time when bacteriostatic information is received, and keeping the UV lamp turned off under the condition that the information sent by the time calculation control module is not received after one working unit time t;

the battery sampling control module is used for receiving the information sent by the market computing control module and controlling the battery power to be reduced after receiving the information entering the low power consumption mode.

One of two contacts of the first contact switch K1 is positioned at the bottom of the UV sterilization component, and the other contact is positioned at the bottom of the box body, namely the UV sterilization component is placed in the box body to enable the two contacts to be contacted/approached so as to enable the K1 to be closed; the two contacts of the second contact switch K2 are located one on top of the UV germicidal module and the other on the upper lid, i.e. only after the upper lid is closed K2 can be closed. Therefore even K3 is closed, if the upper cover does not cover, or the subassembly that disinfects does not put into the box body and can not make the UV lamp bright, promptly, only put into the box body and cover the upper cover at the UV subassembly that disinfects and just can make the UV lamp bright, and the UV light is restricted in the box this moment, and the security is high. When K3 is off, the UV lamp cannot be turned on even if both K1 and K2 are turned on, and the storage box can be used as it is by turning off K3 if the sterilization function is not required.

Preferably, after the information that all three switches are closed is received for the first time, the time calculation control module further receives the information of the states of the switches sent by the switch identification module in real time, and sends the information of closing the UV lamp to the UV lamp control module when the information that the K2 is opened (that is, the upper cover is opened) is received in the time process of t1 of the long sterilization mode, and after the K2 is closed, the time calculation control module sends the information of continuing sterilization to the UV lamp control module, and continues to accumulate the sterilization time until the end of t1 and then enters the bacteriostasis mode. The t1 accumulation mode avoids excessively repeated killing when k2 is opened and closed in the long sterilization mode, saving part of the electric power.

The UV lamp control module controls the UV lamp to be turned off when receiving the information of turning off the UV lamp, and controls the UV lamp to be turned on when receiving the information of continuing sterilization.

Preferably, the time calculation control module sends out information for turning off the UV lamp to the UV lamp control module when receiving the information that the K2 is turned off during the time period t2 of the bacteriostasis mode, sends out information for short sterilization to the UV lamp control module after the K2 is turned on, sends out information for turning off the UV lamp to the UV lamp control module after the time period t3, and continues to accumulate the bacteriostasis time until the time period t2 is finished and then enters the low power consumption mode. Due to the fact that a long sterilization mode with thorough sterilization is already experienced, bacteria in the box can be almost ignored in the bacteriostasis mode, the box cover can be opened for a short time to be covered again when the user takes the articles, and only short-time t3 sterilization needs to be carried out after K2 is closed.

The UV lamp control module controls the UV lamp to be turned on for t3 time after receiving the short sterilization information, and keeps the UV lamp to be turned off under the condition that the information sent by the time calculation control module is not received within t2 time of the bacteriostasis mode.

Preferably, if the short sterilization process receives the information that the K2 is turned off, the time calculation control module sends the information of turning off the UV lamp to the UV lamp control module, and after the K2 is turned on, the time calculation control module sends the information of continuing sterilization to the UV lamp control module, continues to accumulate the sterilization time until the end of t3, then enters the bacteriostasis mode, and continues to accumulate the bacteriostasis time until the end of t2, and then enters the low power consumption mode.

Preferably, the time calculation control module receives the information that any switch is opened in the low power consumption mode, and restarts to enter a new working unit after receiving the information that all three switches are closed. That is, in the low power mode, the system restarts after either switch opens and closes.

Preferably, at any time, the time calculation control module receives the information that K1 or K3 is open, and restarts entering a new work unit after receiving the information that all three switches are closed. Since K1 is a contact switch between the inside of the case and the UV lamp germicidal assembly and typically K1 is arranged between the bottom of the case and the bottom of the assembly, disconnection will only occur when the assembly is removed or dropped out, in which case a long germicidal cycle is required again after the three switches are closed.

Preferably, the time calculation control module is further configured to set a delay time t5, the switch identification module transmits information that one of K1 and K2 is closed to the time calculation control module after recognizing that the switch is closed, the time calculation control module transmits information that the switch is continuously identified to the switch identification module after receiving the information by a delay time t5, the switch identification module continuously identifies the state of the other one of K1 and K2 after receiving the information, and transmits the information that the switch is closed to the time calculation control module after recognizing that the second switch is closed. The contact switch adopts a magnetic switch, and is provided with two contacts, one contact is positioned on the UV lamp sterilization component, the other contact is positioned on the box body/the upper cover, and the switch can be closed when the two contacts are close to or in contact with each other. Because the UV lamp sterilization component is directly placed in the box body, the upper cover can be closed only after the UV lamp sterilization component is put down to close the contact switch K1, and the action requires operation time, namely, a delay time is inevitably existed in the closing of K1 and K2, so that the delay time t5 is designed, and the delay time t5 is 1-3 s. If under the closed condition at K3, the misoperation makes K1 and K2 close simultaneously or short interval with two contacts on the magnet is close to the UV lamp sterilization subassembly, and the UV lamp can light, but must the upper cover not yet covered this moment, and the UV light can leak, has certain potential safety hazard. After the delay time t5 between K1 and K2 is designed, even if the operation is improper, the UV lamp cannot be on, and the safety is higher.

And after the time calculation control module delays the time t5 after receiving the information that the three switches are all closed, the time calculation control module sends out the information of long sterilization, short sterilization or continuous sterilization to the UV lamp control module. Because two contacts of the contact switch can be closed as long as the two contacts are close to each other, under the condition that K1 and K3 are closed, K2 can be closed when the upper cover is not completely closed, and UV light leakage can be caused if the UV lamp is immediately lighted at the moment.

Preferably, the UV lamp sterilization assembly further comprises an LED lamp, the MCU further comprises an LED lamp control module for controlling the LED lamp to be turned on and off, the LED lamp is powered by a battery, when the system enters a long sterilization mode and a bacteriostasis mode, the time calculation control module sends information of the time when the lamp is turned on t3 to the LED lamp control module, the LED lamp control module controls the LED lamp to be turned off after the LED lamp is turned on t3 after receiving the information, and the LED lamp plays a role in prompting.

Preferably, the MCU further comprises a threshold setting module, the threshold setting module is used for setting a lower limit threshold of the electric quantity of the battery,

the time calculation control module is also used for setting a low battery reminder time t4,

the battery sampling control module is also used for acquiring the electric quantity of the battery in real time, comparing the acquired electric quantity information with a threshold value, sending the information to the time calculation control module when the acquired electric quantity is smaller than the threshold value, feeding back the information entering the low power consumption mode to the battery sampling control module by the time calculation control module after receiving the information, sending the information of the time when the LED lamp is turned on t4 to the LED lamp control module, and controlling the LED lamp to be turned off after the LED lamp control module receives the information and then turns on t 4. Because the lamp is bright under the condition of not breaking any switch, so the user can judge that this condition is the electric quantity low, take out the battery charge can, the disinfection receiver is put into to the electricity of having washed, and the system gets into the work unit of a new round after three switches are closed simultaneously.

The invention has the beneficial effects that:

according to the invention, sterilization can be carried out only under the condition that three switches are simultaneously closed, the UV lamp cannot be turned on under the condition that any one switch is opened, and the UV lamp can be turned on under the condition that the K3 is closed only under the condition that the UV sterilization component is in the box body and the upper cover is covered well through the position limitation of the two switches K1 and K2, so that the UV light is limited in the box body, and the safety is high.

The invention can also keep the antibacterial state after long-term sterilization of the storage box, and enter a low-power-consumption mode after one working unit is finished, thereby greatly saving energy consumption under the condition of ensuring the sterilization effect. And because the long sterilization mode is completely sterilized, only short sterilization is needed after the box cover is opened in the bacteriostasis mode, and the energy consumption is further saved.

The utility model provides a sterilization control system of disinfection receiver, includes box body 1 and upper cover 2 as shown in figure 1, is equipped with UV lamp sterilization assembly 3 in the box body 1, is equipped with first contact switch K1 between box body 1 and the UV lamp sterilization assembly 3, is equipped with second contact switch K2 between upper cover 2 and the UV lamp sterilization assembly 3, still is equipped with key switch K3 on box body 1 or the UV lamp sterilization assembly 3, UV lamp sterilization assembly 3 includes battery, MCU and UV lamp, and entire system is by battery powered, the battery with USB interface connection that charges. As shown in fig. 2, the MCU includes a switch recognition module, a time calculation control module, a UV lamp control module and a battery sampling control module,

the switch identification module is used for identifying the on/off of a first contact switch K1, a second contact switch K2 and a key switch K3 and transmitting the on/off state information of the three switches to the time calculation control module;

the time calculation control module is used for setting a long sterilization time t1, a bacteriostasis time t2 and a short sterilization time t3, taking the duration t as a working unit, taking the duration t as t1+ t2, receiving information sent by the switch identification module, entering a long sterilization mode of the working unit after receiving information that all three switches are closed for the first time, sending long sterilization information to the UV lamp control module, starting timing of the first working unit at the same time, sending bacteriostasis information to the UV lamp control module when the accumulated long sterilization time reaches t1, at the moment, the system enters the bacteriostasis mode, and simultaneously, when the accumulated bacteriostasis time reaches t2 (namely after the duration t of the working unit is accumulated to be full), the time calculation control module sends information for entering the low power consumption mode to the battery sampling control module, and at the moment, the system enters the low power consumption mode, in the mode, any switch is switched off and then is switched on, and the system enters a new working unit again;

the UV lamp control module is used for receiving the information sent by the time calculation control module, controlling the UV lamp to be turned on for t1 time when long sterilization information is received, controlling the UV lamp to be turned off for t2 time when bacteriostatic information is received, and keeping the UV lamp turned off under the condition that the information sent by the time calculation control module is not received after one working unit time t;

the battery sampling control module is used for receiving the information sent by the market computing control module and controlling the battery power to be reduced after receiving the information entering the low power consumption mode.

One of two contacts of the first contact switch K1 is positioned at the bottom of the UV sterilization component, and the other contact is positioned at the bottom of the box body, namely the UV sterilization component is placed in the box body to enable the two contacts to be contacted/approached so as to enable the K1 to be closed; the two contacts of the second contact switch K2 are located one on top of the UV germicidal module and the other on the upper lid, i.e. only after the upper lid is closed K2 can be closed. Therefore, even if the K3 is closed, the UV lamp cannot be turned on if the upper cover is not well covered or the sterilization assembly is not placed in the box body. That is, only put into the box body and cover the upper cover and just can make the UV lamp bright at the UV subassembly that disinfects, and the UV light is restricted in the box this moment, and the security is high. When K3 is off, the UV lamp cannot be turned on even if both K1 and K2 are turned on, and the storage box can be used as it is by turning off K3 if the sterilization function is not required.

After the information that all three switches are closed is received for the first time, the time calculation control module further continues to receive the information of the states of the switches sent by the switch identification module in real time, and sends out information for closing the UV lamp to the UV lamp control module when receiving information that the K2 is disconnected (namely the upper cover is opened) in the time process of t1 in the long sterilization mode, and after the K2 is closed, the time calculation control module sends out information for continuing sterilization to the UV lamp control module, and continues to accumulate sterilization time until the end of t1, and then enters the bacteriostasis mode. The t1 accumulation mode avoids excessively repeated killing when k2 is opened and closed in the long sterilization mode, saving part of the electric power. The UV lamp control module controls the UV lamp to be turned off when receiving the information of turning off the UV lamp, and controls the UV lamp to be turned on when receiving the information of continuing sterilization.

The time calculation control module sends out information for turning off the UV lamp to the UV lamp control module when receiving information of K2 disconnection in the t2 time process of the bacteriostasis mode, and after K2 is turned on, the time calculation control module sends out information for short sterilization to the UV lamp control module, and after t3, the time calculation control module sends out information for turning off the UV lamp to the UV lamp control module, and continues to accumulate the bacteriostasis time until t2 is finished, and then enters the low power consumption mode. Due to the fact that a long sterilization mode with thorough sterilization is already experienced, bacteria in the box can be almost ignored in the bacteriostasis mode, the box cover can be opened for a short time to be covered again when the user takes the articles, and only short-time t3 sterilization needs to be carried out after K2 is closed. The UV lamp control module controls the UV lamp to be turned on for t3 time after receiving the short sterilization information, and keeps the UV lamp to be turned off under the condition that the information sent by the time calculation control module is not received within t2 time of the bacteriostasis mode.

If in the short sterilization process, when the information that the K2 is disconnected is received, the time calculation control module also sends the information of closing the UV lamp to the UV lamp control module, and after the K2 is closed, the time calculation control module sends the information of continuing sterilization to the UV lamp control module, continues to accumulate the sterilization time until the end of t3, then enters the bacteriostasis mode, continues to accumulate the bacteriostasis time until the end of t2, and then enters the low power consumption mode.

And the time calculation control module receives the information of the disconnection of any switch in the low power consumption mode and restarts to enter a new working unit after receiving the information of the complete closure of the three switches. That is, in the low power mode, the system restarts after either switch opens and closes.

At any moment, the time calculation control module receives the information that K1 or K3 is opened, and restarts to enter a new work unit after receiving the information that all three switches are closed. Since K1 is a contact switch between the inside of the case and the UV lamp germicidal assembly and typically K1 is arranged between the bottom of the case and the bottom of the assembly, disconnection will only occur when the assembly is removed or dropped out, in which case a long germicidal cycle is required again after the three switches are closed.

The time calculation control module is further used for setting a delay time t5, the switch identification module transmits information of the switch closure to the time calculation control module after identifying that one of the switches K1 and K2 is closed, the time calculation control module transmits information of continuous identification to the switch identification module after delaying the time t5 after receiving the information, the switch identification module continues to identify the state of the other switch of the switches K1 and K2 after receiving the information, and transmits the information of the switch closure to the time calculation control module after identifying that the second switch is closed. The contact switch adopts a magnetic switch, and is provided with two contacts, one contact is positioned on the UV lamp sterilization component, the other contact is positioned on the box body/the upper cover, and the switch can be closed when the two contacts are close to or in contact with each other. Because the UV lamp sterilization component is directly placed in the box body, the upper cover can be closed only after the UV lamp sterilization component is put down to close the contact switch K1, and the action requires operation time, namely, a delay time is inevitably existed in the closing of K1 and K2, so that the delay time t5 is designed, and the delay time t5 is 1-3 s. If under the closed condition at K3, the misoperation makes K1 and K2 close simultaneously or short interval with two contacts on the magnet is close to the UV lamp sterilization subassembly, and the UV lamp can light, but must the upper cover not yet covered this moment, and the UV light can leak, has certain potential safety hazard. After the delay time t5 between K1 and K2 is designed, even if the operation is improper, the UV lamp cannot be on, and the safety is higher.

And the time calculation control module is used for sending out long sterilization, short sterilization or continuous sterilization information to the UV lamp control module after delaying the time t5 after receiving the information that the three switches are all closed. Because two contacts of the contact switch can be closed as long as the two contacts are close to each other, under the condition that K1 and K3 are closed, K2 can be closed when the upper cover is not completely closed, and UV light leakage can be caused if the UV lamp is immediately lighted at the moment.

The UV lamp sterilization assembly further comprises an LED lamp 4, the LED lamp can be arranged at any position where the surface of the UV lamp sterilization assembly can be seen, the MCU further comprises an LED lamp control module used for controlling the LED lamp switch, the LED lamp is powered by a battery, the system is in a long sterilization mode and a bacteriostatic mode, the time calculation control module sends information of the time of lighting t3 to the LED lamp control module, and the LED lamp control module controls the LED lamp to be turned off after receiving the information and lighting t 3.

The MCU also comprises a threshold setting module which is used for setting a lower limit threshold of the electric quantity of the battery, the specific threshold is determined according to the capacity of the battery,

the time calculation control module is also used for setting low-power reminding time t4, t2 > t1 > t3 > t4 > t5, the specific setting of the first four times is determined according to the size of the storage box, generally, for a 50cm square box, under the condition that a 3w quartz dual-waveband UVC ultraviolet lamp is adopted, t1 does not exceed 10min, t2 does not exceed 100min, t3 does not exceed 20s, and t4 does not exceed 10 s.

The battery sampling control module is also used for acquiring the electric quantity of the battery in real time, comparing the acquired electric quantity information with a threshold value, sending the information to the time calculation control module when the acquired electric quantity is smaller than the threshold value, feeding back the information entering the low power consumption mode to the battery sampling control module by the time calculation control module after receiving the information, sending the information of the time when the LED lamp is turned on t4 to the LED lamp control module, and controlling the LED lamp to be turned off after the LED lamp control module receives the information and then turns on t 4. Because the lamp is bright under the condition of not breaking any switch, so the user can judge that this condition is the electric quantity low, take out UV lamp sterilization subassembly charge for the battery through the UBS interface that charges can, it puts into the disinfection receiver to have filled the electricity, and the system gets into the work unit of a new round after three switches are closed simultaneously.

Example 1

In the case of using a 3w quartz dual-band UVC ultraviolet lamp for a storage box having a size of 130mm × 230mm × 70mm, the long sterilization time t1 is generally 6min, the bacteriostatic time t2 is generally 54min, the short sterilization time t3 is generally 10s, the low-battery reminder time t4 is generally 5s, and the delay time t5 is generally 2 s. With K3 open, K1, K2 cannot turn on the UV lamp even if they are all closed; under the condition that the K3 is closed, the UV sterilization component is placed in the box body, the system recognizes that the K1 is closed, the cover is closed, the action of the cover can be completed within 2s even for children, therefore, the system delays for 2s to start recognizing the K2, and after recognizing that the K2 is closed, the three switches are all in a closed state (the K3 can be closed finally after the K1 and the K2 are closed). Delay 2s after the first three switches are all closed to ensure the cartridge is sealed before entering the long sterilization mode: lighting an LED lamp for 10s, and sterilizing for 6min by using UV; entering a bacteriostatic mode after the long sterilization is finished: lighting an LED lamp for 10s, and sterilizing for 54min by UV; and after the bacteriostasis is finished (namely after one working unit is finished), entering a low power consumption mode. During the period, if the upper cover is opened and then closed in the long sterilization mode, the long sterilization is continued to be accumulated until the time is up to 6 min; if the upper cover is opened and then closed in the bacteriostasis mode, stopping sterilizing after UV sterilization for 10s and continuing to cumulatively inhibit bacteria until 54min is full; and if the upper cover is opened and then closed in the low power consumption mode, restarting a new 60min working unit. In either mode, a new 60min work unit is restarted whenever the key switch K3 is closed.

In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
