DETAILED DESCRIPTION

[0029] The preferred embodiments of the utility model will be described in detail below with reference to the drawings, and those skilled in the art will appreciate that these descriptions are only descriptive, exemplary, and should not be interpreted as limiting the protection scope of the utility model.

[0030] It should be noted that: similar reference numerals represent similar items in the following drawings, so once an item is defined in one drawing, it can not be further defined and explained in subsequent drawings.

[0031] This embodiment mainly describes the circuit system of the multifunctional sound control vacuum sealing machine which is simple to operate and can select the extraction module according to the articles, and the specific steps are as follows:

[0032] For example, Figures 1-5As shown, the circuit system of the multifunctional sound control vacuum sealing machine includes a machine body, a control circuit and a control system, the control circuit is installed in the machine body, and the control system is inducted and controlled by the control circuit (the structure of the machine body is not shown in the drawing).

[0033] In this embodiment, the control system includes an information processing module 1, which is the core of the control system, receives signals from other modules, processes and decides according to the preset program, and finally outputs control instructions to the execution module;

[0034] The information processing module 1 is connected with a sound control module 2 that receives and transmits signals to the information processing module 1 and a touch module 3 that transmits signals to the information processing module 1 through touch options, and the sound control module 2 and the touch module 3 are connected with a mode module 4, a point extraction module 5 and an external extraction module 6, wherein the mode module 4 has multiple choices, including dry selection 4a, wet selection 4b, liquid selection 4c and powder selection 4d, and the user can choose according to the nature of the goods in the packaging bag and the packaging characteristics.

[0035] The information processing module 1 is connected with an extraction and compression module 7 and a sealing module 8, the extraction and compression module 7 is connected with a vacuum negative pressure pump 9 in the control circuit, and the sealing module 8 is connected with a heating wire 10 in the control circuit, and a vacuum chamber is arranged on the machine body, in use, the bag opening of the packaging bag needs to be inserted into the vacuum chamber, and the information processing module 1 can control the extraction and compression module 7, i.e. the vacuum negative pressure pump 9 to work on the vacuum chamber, and the information processing module 1 can control the sealing module 8, i.e. the heating wire 10 to heat and seal the bag of the packaging bag, preferably, the vacuum negative pressure pump 9 can be directly used as the extraction and compression module 7, and the heating wire 10 can be directly used as the sealing module 8.

[0036] In order to ensure that the influence of the pressure in the vacuum chamber on the goods in the packaging bag is reduced when the goods are extracted, the information processing module 1 is connected with a pressure sensing module 11, the control circuit includes a pressure sensor 12 connected with the pressure sensing module 11, the pressure sensor 12 can sense the pressure value in the vacuum chamber and transmit the pressure value to the information processing module 1, the information processing module 1 analyzes the received pressure value, so that the vacuum chamber opening and closing module 19 can judge whether the extraction and compression are completed according to the pressure value fed back by the pressure sensor 12, i.e. control the air cylinder 20 to drive the chamber cover to seal or open the vacuum chamber.

[0037] The vacuum negative pressure pump 9 in the control circuit, i.e. the motor (MOTOR1 and MOTOR2) is controlled by NPN transistor (Q5, Q6, Q7, Q8), the heating wire 10 (HEAT) is controlled by relay (SV1 and SV2), the relay is driven by NPN transistor (Q7), and the pressure sensor 12 (KBQ-02B) is used to detect the change of pressure.

[0038] In order to avoid the heating time of the heating wire 10 being too long, the information processing module is connected with a timing module 13, which can control the heating time of the heating wire.

[0039] When the plurality of packaging bags are continuously sealed, the temperature in the vacuum chamber is prone to be too high. In the embodiment, the information processing module 1 is connected with an overheating protection module 14, and the control circuit includes a temperature sensor 15 capable of detecting the temperature in the vacuum chamber. The temperature sensor 15 is connected with the overheating protection module 14, and the temperature sensor 15 feeds back the sensed temperature to the information processing module 1. Within the timing time of the timing module 13, the information processing module 1 judges whether the temperature is too high. When the temperature is too high, the information processing module 1 controls the heating wire 10 to stop heating and sealing.

[0040] In order to facilitate the observation of whether the heating wire 10 is in sealing work, the control circuit further includes an overheating lamp 16. When the overheating lamp 16 is on, the heating wire 10 is forced to stop heating. After the temperature drops and the overheating lamp 16 is extinguished, the heating wire 10 can continue to heat and seal.

[0041] Since the vacuum sealing machine is externally connected with the packaging bag or bottle in the state of the external extraction module 6, the external extraction module 6 is not connected with the sealing module 8, and when the external extraction module 6 is in operation, the sealing module 8, i.e. the heating wire 10, will not start work.

[0042] The mode module 4, the point extraction module 5 and the external extraction module 6 are connected with an automatic module 17 and a stop module 18. The automatic module 17 can control the vacuum negative pressure pump 9, and the stop module 18 can control the vacuum negative pressure pump 9 and the heating wire 10 to stop work.

[0043] In actual operation, the voice control module 2 can judge the selection required by the user through voice recognition function, and automatically control the extraction and sealing modules 7 and 8 to perform corresponding extraction and sealing operations according to the selection. The touch module 3 allows the user to select the mode through external touch, and then touch the automatic module 17 and the sealing module 8 to realize corresponding extraction and sealing operations, thereby providing the user with multiple operation options.

[0044] In the application, the voice control module 2 of the vacuum sealing machine is set, so that the user can select the module through voice without releasing the hand. In the case of ensuring that the object falls out of the packaging bag, the vacuum sealing machine can perform vacuum extraction and sealing treatment through voice, which is simple and convenient. The selection of the extraction module can select the object in the packaging bag, and the vacuum sealing machine can adjust the extraction force according to the nature of the object and the packaging requirement, so as to meet the vacuum packaging requirements of different objects and ensure the integrity of the object.

[0045] In addition, the utility model still sets up a variety of protection module and automation control module, improved the security, stability and intelligent level of equipment.

[0046] As Figures 1-5 As shown in the information processing module 1 is connected with the vacuum chamber opening and closing module 19 that can open or seal the vacuum chamber, and the body is equipped with the chamber body and chamber cover, the chamber cover seals the cover and forms the vacuum chamber between the chamber cover and the chamber body, and the control circuit is electrically connected with the cylinder 20, and the vacuum chamber opening and closing module 19 can control the cylinder 20 to drive the chamber cover to move, realize the chamber cover seals or opens the vacuum chamber, to ensure that the chamber cover seals the chamber body, after the chamber cover closes the chamber body, the cylinder 20 can continue to work for 5 seconds and then stop.

[0047] The vacuum chamber opening and closing module 19 includes the electromagnetic valve one 21 and the electromagnetic valve two 22 in the control circuit, the electromagnetic valve one 21 is connected with the cylinder 20, and the electromagnetic valve two 22 is connected with the vacuum negative pressure pump 9, when the pressure extraction or sealing is finished, the electromagnetic valve one 21 connected with the cylinder 20 or the electromagnetic valve two 22 connected with the vacuum negative pressure pump 9 acts, releases the negative pressure in the vacuum chamber, the cylinder 20 restores the default state by the elastic force of the internal spring, the vacuum chamber is opened, preferably, after the pressure extraction and sealing, the electromagnetic valve one 21 and the electromagnetic valve two 22 can act simultaneously.

[0048] Because the sealing and the pressure extraction can be independently operated, the cylinder 20 and the vacuum negative pressure pump 9 are independently controlled by the electromagnetic valve one 21 and the electromagnetic valve two 22 one by one, and the electromagnetic valve (Solenoid Valve1 and Solenoid Valve2) in the control circuit is controlled by the NPN transistor (Q4, Q5).

[0049] Because the wetness selection 4b state, the vacuum sealing machine usually extracts the liquid in the packaging bag to the vacuum chamber, to avoid the liquid overflow in the vacuum chamber, the information processing module 1 is connected with the overflow protection module 23, the control circuit includes the photoelectric sensor or water level sensor 24 that can sense the water level height in the chamber body, the photoelectric sensor or water level sensor 24 feeds back the water level height sensed to the information processing module 1, the information processing module 1 judges whether the water level in the vacuum chamber is too high through the feedback water level height, and the pressure extraction module 7 controls whether the vacuum negative pressure pump 9 continues to work.

[0050] The control circuit further includes the overflow lamp 25, when the photoelectric sensor or water level sensor 24 detects that the water level in the vacuum chamber is too high, the overflow lamp 25 is bright, and the pressure extraction module 7 cannot control the vacuum negative pressure pump 9 to work.

[0051] At this time, in order to facilitate the cleaning of the liquid in the vacuum tank, the tank body can be detachably installed, and the information processing module 1 is connected with an installation detection module 26, the installation detection module 26 can detect whether the tank body is installed in place, the control circuit includes a key 27, the key 27 is connected with the installation detection module 26 and the water overflow lamp 25, in the state that the tank body is installed in place, the tank body is pressed on the key 27, and when the water level sensed by the water level sensor is too high, the water overflow lamp 25 is bright, and after the tank body is removed, the water overflow lamp 25 remains in a constant bright state, and when the tank body is installed in place again and presses the key 27, the water overflow lamp 25 is extinguished.

[0052] As shown in Figures 1-5 The information processing module 1 is connected with a prompt module 28, the prompt module 28 prompts the completion of the vacuum extraction or sealing, the prompt module 28 includes an explicit voice prompt 28a and a concise prompt 28b, and the voice control module 2 is connected with a mute module 31, after the voice trigger or the point touch trigger, the prompt module 28 can be converted from the explicit voice prompt 28a to the concise prompt 28b, preferably, the mute module 31 can be selected or deselected by voice or point touch.

[0053] As shown in the explicit voice prompt 28a state, after the completion of the vacuum extraction and sealing, the voice prompt is “Dripping, the work has been completed, please take away the vacuum bag”, if the vacuum extraction and sealing are continuous, only “Dripping” prompt; and in the concise prompt 28b state, only the dripping prompt sound.

[0054] Preferably, the prompt module 28 can be connected with a loudspeaker or a loudspeaker to enlarge the voice volume of the prompt module 28.

[0055] In order to reduce the energy consumption of the vacuum extraction and sealing machine in the non-working state, the information processing module is connected with a sleep module 29 and a timing module 30, the timing module 30 usually times 30 seconds, after the timing of the timing module 30 is ended, the control system and the control circuit enter the sleep state, and the user can wake up the machine through the voice control module 2 and the touch module 3, end the sleep state and continue to operate.

[0056] When the voice control operation is performed under the voice control module 2, the voice such as “Xiaozhi, wet automatic” can be used for instruction operation, wherein “Xiaozhi” is the wake-up word in the information processing module 1 as the device trigger, which can be replaced according to the manufacturer's setting.

[0057] Preferably, the body is usually marked with the words stop, automatic, mode, dry, wet, oily, powder, sealing, point extraction, external extraction, overheating, overflow, etc. corresponding to the corresponding module and lamp. Here, stop, automatic, mode, dry, wet, oily, powder, sealing, point extraction, external extraction can be prompted by the way of background light. The dry selection 4a, wet selection 4b, liquid selection 4c, and powder selection 4d are distributed in a ring shape. After the light touch mode module 4, the dry selection 4a, wet selection 4b, liquid selection 4c, and powder selection 4d are arranged around the numbers in the middle, and the four selections will be in turn bright background light.

[0058] For example, in oily selection, light touch automatic, the cylinder 20 starts to run first, and the vacuum chamber upper cover is closed. The cylinder 20 can continue to work for 5 seconds and then stop. At this time, the vacuum negative pressure pump 9 starts to extract the air in the vacuum chamber to the pressure standard. The pressure sensor 12 transmits the pressure value, and the vacuum negative pressure pump 9 stops vacuumizing and runs the heating wire to complete the sealing. The heating wire runs for 3 seconds, and the vacuum sealing process is completed. The electromagnetic valve connected with the cylinder 20 and the electromagnetic valve connected with the vacuum negative pressure pump 9 are simultaneously actuated to release the internal negative pressure. The cylinder 20 is restored to the default state by the elastic force of the internal spring, and the vacuum chamber is opened, and the operation is completed.
