[0002] In laboratories, medicine storage rooms and other hazardous chemical storage units, a two-person procedure is generally adopted for receiving and sending, and two-person custody. This custody procedure is often implemented in a two-person double-lock mode in actual use. However, the compliance of this execution mode is poor, especially when one person is on duty at night, and the inspection requirement must be opened by two people with two locks, checked and registered once a day, and each access needs to be registered, and two people must sign and register. Paper records are incomplete, and quality control personnel need to check and re-register each time, which takes a certain amount of time to register every day. More importantly, the number of hazardous chemicals in each hazardous chemical storage unit is different, especially some hazardous chemical storage units have many types of hazardous chemicals, a large number of hazardous chemicals, and many people taking them. In the face of the defects of traditional hazardous chemical storage units that cannot effectively implement hazardous chemical storage and access procedures, it is necessary to propose an intelligent hazardous chemical cabinet.

[0081] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0082] The present application provides a smart hazardous chemicals cabinet.

[0083] like Figure 1 As shown, in one embodiment of the present application, an intelligent hazardous chemicals cabinet is electrically connected to the host computer identity storage system, and the intelligent hazardous chemicals cabinet includes an identity identifier 100, a level centralized communicator 200, a level responder 300, an electronic scale 400, a cabinet body 500, a shelf 600, a limit lock 700 and a door lock 800.

[0084] The cabinet body 500 includes a top plate 510 and a bottom plate 520, and a first wall plate 530, a second wall plate 540, a back plate 550 and a cabinet door 560 are arranged between the top plate 510 and the bottom plate 520. The top plate 510, the bottom plate 520, and the first wall plate 530, the second wall plate 540, the back plate 550 and the cabinet door 560 are arranged between the top plate 510 and the bottom plate 520 to surround and form a rectangular placement area. The back plate 550 is fixedly connected between the first wall plate 530 and the second wall plate 540. The first wall plate 530 is perpendicular to the horizontal plane, the second wall plate 540 is perpendicular to the horizontal plane, the first wall plate 530 and the second wall plate 540 are parallel to each other, the back plate 550 and the first wall plate 530 are perpendicular to each other, the back plate 550 and the horizontal plane are perpendicular to each other, the cabinet door 560 is rotatably connected to the second wall plate 540, and the cabinet door 560 and the first wall plate 530 are mutually clamped.

[0085] The structure of each of the layer panels 600 is the same, a plurality of clamping parts 710 are provided on the top surface of each of the layer panels 600, each of the layer panels 600 is parallel to the horizontal plane, each of the layer panels 600 is perpendicular to the first wall panel 530, and each of the layer panels 600 is clamped between the first wall panel 530 and the second wall panel 540.

[0086] At least one electronic scale 400 is embedded in the top surface of each layer plate 600 . The number of the electronic scales 400 is equal to the number of the clamping portions 710 . The weighing surface of each electronic scale 400 carries a clamping portion 710 .

[0087] Each of the limit locks 700 has the same structure, and the number of the limit locks 700 is equal to the number of the clamping parts 710, and each clamping part 710 is fixedly connected with a limit lock 700. The number of the limit locks 700 is relative to the number of the level transponders 300, and each limit lock 700 is electrically connected to one of the level transponders 300.

[0088] The door lock 800 is disposed between the cabinet door 560 and the first wall plate 530 , and the door lock 800 is electrically connected to one of the level transponders 300 .

[0089] The identity identifier 100 is disposed on the cabinet door 560 , and the identity identifier 100 is electrically connected to the host computer identity storage system.

[0090] The level centralized communicator 200 is electrically connected to the host computer identity storage system.

[0091] Each level transponder 300 corresponds to a limit lock 700, and each level transponder 300 is electrically connected to the level centralized communicator 200. Specifically, the identity identifier 100 can use an NFC near-field radio frequency device. NFC, the full name is Near Field Communication, also known as "near field communication".

[0092] The level-concentrated communicator 200 may select the ADC-LCD driver model UTC-M7240 and the mixed-signal front end model AD9963.

[0093] Simply, an ADC-LCD driver of model UTC-M7240 is electrically connected to a mixed signal front end of model AD9963, and the mixed signal front end of model AD9963 is communicatively connected to an identity storage system of a host computer.

[0094] The multiple level transponders 300 are all electrically connected to an ADC-LCD driver of model UTC-M7240. The electronic scale 400 is communicatively connected to a mixed signal front end of model AD9963.

[0095] The level responder 300 can select an I / O controller of model MEC1621.

[0096] Working principles of the identity identifier 100, the level centralized communicator 200 and the level transponder 300:

[0097] The host computer identity storage system accepts the operator's hazardous chemicals application requirements in advance. When two operators scan the identity identifier 100 through the identity card, the identity identifier 100 transmits the information of the two operators to the host computer identity storage system. The host computer identity storage system verifies and gives a level signal to the level centralized communicator 200 after passing. The level centralized communicator 200 transfers the action level signal to the level responder 300. The level responder 300 performs the opening and closing tasks of the door lock 800 and the limit lock 700.

[0098] The present application relates to an intelligent hazardous chemicals cabinet, which reads the identification level signals of two identity cards through an identity identifier 100 externally connected to the host computer identity storage system. The host computer identity storage system receives the identification level signals of the two identity cards and gives the action level of opening the door lock 800 to the level centralized communicator 200. The level centralized communicator 200 gives the action level to the level transponder 300 electrically connected to the door lock 800, and the door lock 800 is opened. Based on the level signal of the host computer identity storage system, the level centralized communicator 200 can send the action level to the level transponder 300 to open the limit lock 700, so that the operator can take the hazardous chemicals. Specifically, the clamping portion 710 of each layer plate 600 is unlocked by the limit lock 700 to open the limit of the container of hazardous chemicals. Each limit lock 700 is electrically connected to a level transponder 300. After the level transponder 300 receives the action level sent by the level centralized communicator 200, the limit lock 700 will be opened or closed. During this process, the container of hazardous chemicals can be picked up and placed. It is worth mentioning that the electronic scale 400 will record the weight data of the container and transmit the data back to the host computer identity storage system through the level centralized communicator 200. This solves the defect that traditional hazardous chemical storage units cannot effectively execute the hazardous chemical storage and access procedures.

[0099] like Figure 2 As shown, in one embodiment of the present application, the clamping portion 710 includes a base 720 and a locking cover 730. The inner diameter of the base 720 is equal to the outer diameter of the locking cover 730. The base 720 is sleeved on the outer peripheral surface of the locking cover 730. The electronic scale 400 is arranged close to the bottom surface of the base 720.

[0100] Specifically, the base 720 is sleeved on the outer peripheral surface of the locking cover 730, and the base 720 and the locking cover 730 form a sealed empty shell, which is used to accommodate a container for holding chemical reagents.

[0101] When the container is taken, the locking cover 730 is moved to ensure that the container is unlocked.

[0102] When the container is put back, the locking cover 730 is inserted into the inner cavity of the base 720 to lock it.

[0103] It is worth mentioning that the electronic scale 400 is arranged in the inner cavity of a clamping portion 710. During the process of taking and putting back the container, the electronic scale 400 can weigh the weight of the container and send back the weight data to save the weight of the hazardous chemicals taken by the operator.

[0104] like Figure 3As shown, in one embodiment of the present application, the clamping portion 710 further includes a locking pin 740. The locking pin 740 includes a housing 741, a pin 742, a gear 743 and a motor 744. The outer wall of the housing 741 is fixedly connected to the base 720. The gear 743 is fixedly connected to the power shaft of the motor 744. The pin 742 is provided with a plurality of teeth 745. The teeth 745 of the pin 742 mesh with the gear 743. The gear 743 and the motor 744 are arranged in the inner cavity of the housing 741. The connecting portion of the pin 742 and the teeth 745 is arranged in the inner cavity of the housing 741. The pin 742 passes through the housing 741 and has a preset portion extending out of the housing 741. The motor 744 is electrically connected to a level transponder 300.

[0105] Specifically, the main function of the locking pin 740 is to achieve unlocking and locking of the locking cover 730 and the base 720 through the extension and retraction of the pin rod 742 in the housing 741 .

[0106] like Figure 3 As shown, in one embodiment of the present application, the side wall of the base 720 is provided with a first through hole 721. The locking cover 730 is provided with a second through hole 722. The axial center axis of the first through hole 721 coincides with the axial center axis of the second through hole 722. The pin 742 extends out of a preset portion of the housing 741 and is simultaneously clamped in the first through hole 721 and the second through hole 722.

[0107] Specifically, the axial center axis of the first through hole 721 coincides with the axial center axis of the second through hole 722, and the predetermined portion of the pin 742 extending out of the housing 741 is clamped in the inner cavity of the first through hole 721 and the inner cavity of the second through hole 722. The locking cover 730 and the base 720 are unlocked and locked by the extension and contraction of the pin 742 in the housing 741.

[0108] The present application relates to an intelligent hazardous chemicals cabinet, in which the locking portion 710 of each shelf 600 is unlocked by a limit lock 700 to open the limit of the container of hazardous chemicals. Each limit lock 700 is electrically connected to a level responder 300. After the level responder 300 receives the sending action level of the level centralized communicator 200, the limit lock 700 will be opened or closed. During this process, the container of hazardous chemicals can be picked up and placed. It is worth mentioning that the electronic scale 400 will record the weight data of the container and transmit the data back to the host computer identity storage system through the level centralized communicator 200. This solves the defect that traditional hazardous chemical storage units cannot effectively execute hazardous chemical access procedures.

[0109] like Figure 2As shown, in one embodiment of the present application, the layer board 600 includes a first sub-board 610, a second sub-board 620 and a third sub-board 630. The clamping portion 710 is disposed on the top surface of the first sub-board 610. The first sub-board 610 and the second sub-board 620 are attached to each other. A wire is disposed between the first sub-board 610 and the second sub-board 620. The third sub-board 630 is disposed close to the second sub-board 620.

[0110] Specifically, the clamping portion 710 is disposed on the top surface of the first sub-plate 610, and the wire controlling the limit lock 700 is disposed between the first sub-plate 610 and the second sub-plate 620. This is conducive to protecting the wire of the limit lock 700 from being corroded by volatile substances of hazardous chemicals.

[0111] like Figure 2 As shown, in one embodiment of the present application, the third sub-plate 630 is disposed close to the second sub-plate 620 , and there is a cavity between the third sub-plate 630 and the second sub-plate 620 .

[0112] like Figure 2 As shown, in one embodiment of the present application, the first sub-plate 610 is provided with a plurality of first drainage holes 611. Each of the first drainage holes 611 is a long hole. The plurality of first drainage holes 611 are parallel to each other. The second sub-plate 620 is provided with a plurality of second drainage holes 621. Each of the second drainage holes 621 is a long hole. The plurality of second drainage holes 621 are parallel to each other. The number of the first drainage holes 611 and the second drainage holes 621 is the same, each first drainage hole 611 has a corresponding second drainage hole 621, and the first drainage hole 611 and the second drainage hole 621 are connected to each other. Specifically, the first drainage hole 611 and the second drainage hole 621 are connected, which is conducive to the presence of a cavity between the third sub-plate 630 and the second sub-plate 620 and the connection with the first drainage hole 611 and the second drainage hole 621. When the hazardous chemicals leak, the hazardous chemicals can flow into the cavity between the third sub-plate 630 and the second sub-plate 620, thereby preventing the leaked hazardous chemicals from further volatilizing and detonating.

[0113] like Figure 4As shown, in one embodiment of the present application, the intelligent hazardous chemicals cabinet also includes a negative pressure device 910. The negative pressure device 910 includes a negative pressure shell 911, a negative pressure membrane 912 and a purification liquid tank 913. The negative pressure shell 911 is provided with a first connection hole 914, a second connection hole 915 and a third connection hole 916. The first connection hole 914 is in communication with the inner cavity of the cabinet 500. The negative pressure membrane 912 is clamped on the hole wall of the second connection hole 915. The purification liquid tank 913 includes a tank body 917, a one-way conduit 918 and an air duct 919. One end of the one-way conduit 918 is in communication with the third connection hole 916. The other end of the one-way conduit 918 is in communication with the tank body 917, and the one-way conduit 918 is arranged close to the bottom surface of the tank body 917. One end of the air guide tube 919 extends into the tank body 917 and communicates with the tank body 917 , and the other end of the air guide tube 919 extends out of the tank body 917 . The air guide tube 919 is disposed close to the top surface of the tank body 917 .

[0114] Specifically, during the storage of hazardous chemicals, volatile hazardous chemicals are often stored, and such volatile hazardous chemicals are mainly toxic and explosive. Therefore, it is necessary to use the negative pressure device 910 to purify the air inside the cabinet 500 .

[0115] More specifically, the vibration of the negative pressure membrane 912 causes the air pressure in the negative pressure shell 911 to change. During the process of the air pressure change in the internal space of the negative pressure shell 911, the negative pressure shell 911 absorbs air into the purification liquid tank 913 to purify the air.

[0116] This greatly reduces the residual concentration of volatile hazardous chemicals in the air.

[0117] like Figure 4 As shown, in one embodiment of the present application, the negative pressure device 910 also includes a first one-way valve 920 and a connecting pipe 940. One end of the connecting pipe 940 extends into the inner cavity of the cabinet 500, and the other end of the connecting pipe 940 is connected to the first connecting hole 914. The one-way conduit 918 includes a second one-way valve 921 and a conduit body 922. The first one-way valve 920 is arranged on the connecting pipe 940. The first one-way valve 920 introduces the air in the inner cavity of the cabinet 500 into the negative pressure shell 911 in a one-way manner. The second one-way valve 921 is connected to the conduit body 922. The second one-way valve 921 introduces the air in the inner cavity of the negative pressure shell 911 in a one-way manner into the tank 917.

[0118] Specifically, the first one-way valve 920 introduces the air in the cabinet 500 into the negative pressure shell 911 in one direction, and the second one-way valve 921 introduces the air in the negative pressure shell 911 into the purified liquid tank 913 in one direction.
