Background
The cabinet door of the sterilizing cabinet product must be completely closed to allow the sterilizing function to be performed. If the door closing detection is unreliable, the disinfection cabinet cannot work normally. If the door closing detection is unstable, the cabinet door is not completely closed to perform disinfection, and the disinfection ultraviolet rays leak, so that potential safety hazards can be brought to users.
In the prior art, the door closing detection scheme of the disinfection cabinet mainly comprises two types:
(1) And a micro switch is adopted, and the mechanical action when the door is closed is utilized to touch the micro switch to detect the door closing of the disinfection cabinet. However, the micro-switch is complex to install, is easy to wet, is mechanically worn, causes failure, cannot work normally, and is also possibly blocked, so that safety failure is caused.
(2) The single-way Hall device and the magnet are adopted, and the Hall device and the magnet are close to each other by utilizing the action when the door is closed, so that the door closing of the disinfection cabinet is detected. However, the single-way Hall causes the door frame to slightly shift, or the magnet is weakened, or the Hall fails, so that the machine cannot work normally, and the reliability is low. The single-way Hall product can not detect the closing door and the machine can not enter the disinfection working state because more customer complaints are generated.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model provides a door closing detection device of a disinfection cabinet, which adopts double-path Hall detection logic to ensure the reliability of two paths of detection and increase the detection stability.
In order to achieve the above technical solution, the present utility model provides a door closing detection device of a disinfection cabinet, including: magnet, hall switch A, hall switch B, MCU controller and power strip, wherein magnet installs on the door frame of cabinet-type air conditioner main part, and hall switch A and hall switch B parallelly connected install on the door body of cabinet-type air conditioner main part, and hall switch A and hall switch B each other are backup relation, hall switch A and hall switch B respectively with MCU controller electric connection, MCU controller installs on the power strip, and the power strip meets the electricity.
In the above technical scheme, when the door body of the cabinet main body is closed in actual operation, the door closing signals of the hall switch a and the hall switch B are effective, so that the machine can be allowed to normally operate. The Hall switch A and the Hall switch B are in backup relation and are used for preventing detection errors caused by Hall failure or magnet position deviation. When normal customer uses, if the door frame takes place to shift, perhaps magnetic force decay, when closing the door, hall switch A circuit has the signal, and hall switch B circuit does not have the signal, or hall switch A circuit does not have the signal, and hall switch B circuit has the signal, and MCU controller still can detect normal closing the door, ensures that the machine can normally work to can increase detection stability.
Preferably, the disinfection cabinet also comprises a temperature detector, wherein the temperature detector is electrically connected with the MCU controller, can detect the temperature in the disinfection cabinet in real time through the temperature detector, and forms a complementary relation with the lines of the Hall switch A and the Hall switch B.
Preferably, the automatic control device further comprises a display module, wherein the display module is connected with the MCU controller, two paths of state display are arranged on the display module, H1 is displayed when a Hall switch A circuit is abnormal, H2 is displayed when a Hall switch B circuit is abnormal, HH is displayed when both the Hall switch A circuit and the Hall switch B circuit are normal, so that the user can clearly know which path is abnormal on the disinfection cabinet, and the rapid fault removal is realized.
The door closing detection device of the disinfection cabinet has the beneficial effects that: the utility model has simple structure and ingenious design, adopts double-path Hall detection logic, ensures reliable detection of two paths and increases detection stability. Compared with a micro switch, the scheme is non-contact, long in service life and high in reliability. Compared with a single-path Hall, the utility model adopts the logic of a double-path Hall, and has the characteristics of good compatibility, long service life and high stability. The cost of the hall device is low. Only one single accessory is added, and one set of logic is designed, so that the service life and reliability of the product can be greatly improved, and the problem of market complaints is solved.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments obtained by those skilled in the art without making any inventive effort are within the scope of the present utility model.
Examples: a door closing detection device of a disinfection cabinet.
Referring to fig. 1, a door closing detecting device of a sterilizer comprises: magnet 1, hall switch A2, hall switch B3, MCU controller 4, power strip 5, temperature detector 6 and display module, wherein magnet 1 is installed on the door frame of cabinet body, and hall switch A2 and hall switch B3 are parallelly connected to be installed on the door body of cabinet body, and hall switch A2 and hall switch B3 each other are backup relation, hall switch A2 and hall switch B3 respectively with MCU controller 4 electric connection, MCU controller 4 installs on power strip 5, power strip 5 connects the electricity, provides the power for MCU controller 4, temperature detector 6 and MCU controller 4 electric connection can real-time detection disinfect the temperature in the cabinet to form complementary relation with hall switch A2 and hall switch B3 circuit between, display module is connected with MCU controller 4, is provided with two way status display on the display module, shows H1 when hall switch A2 circuit is unusual, shows H2 when hall switch B3 circuit is unusual, shows the quick-operation that the cabinet can be in order to get rid of the unusual route on the normal clear and clear that can be in order to get rid of the unusual route when hall switch A2 circuit and hall switch B3.
