Description

Technical Field

[0001] This utility model relates to the field of vacuum equipment technology, and in particular to a current-voltage measuring vacuum device and a baby bottle. Background Technology

[0002] Existing vacuum pumping devices can extract air from a cavity to achieve the purpose of vacuuming. Once the required vacuum level is reached, the control module can control the vacuum pumping device to stop. Current vacuum pumping devices are equipped with vacuum level sensors to detect the vacuum level inside the cavity. When the actual vacuum level reaches the vacuum level threshold, the control module can determine that the required vacuum level has been reached. However, vacuum level sensors are expensive and require a certain amount of space, resulting in a large overall size of the vacuum pumping device, which is not convenient for users to carry easily.

[0033] like Figures 1 to 7As shown, a current-voltage measuring vacuum device according to a first aspect embodiment of the present invention includes a housing 100, a vacuuming assembly 200, a current detection module 300, and a control module 400. The housing 100 is provided with a connection structure 140 for connecting with a bottle body. The housing 100 is provided with an extraction port 120. The vacuuming assembly 200 is disposed inside the housing 100, and the input end of the vacuuming assembly 200 is connected to the extraction port 120. The current detection module 300 is connected to the vacuuming assembly 200 to detect the operating current of the vacuuming assembly 200. The control module 400 is disposed inside the housing 100 and is connected to the current detection module 300 and the vacuuming assembly 200 to control the start and stop of the vacuuming assembly 200 according to the magnitude of the operating current.

[0034] Depending on the specific shape of the container being evacuated, the configuration of the shell 100 and the connecting structure 140 can be adaptively adjusted. For example, in some embodiments of this utility model, the shell 100 can be in the shape of a cap, the shell 100 is provided with a sink 110, the connecting structure 140 includes an internal thread structure provided on the inner side wall of the sink 110, and an external thread structure provided on the outer side wall of the bottle mouth. The shell 100 can cover the bottle mouth of the bottle, and the internal thread structure and the external thread structure are screwed together to make the shell 100 tightly connected to the bottle.

[0035] The housing 100 is provided with a sealing ring 150 on the bottom surface of the settling tank 110. The extraction port 120 is located on the wall surface of the housing 100 within the sealing ring 150. The bottle mouth end can be pressed against the sealing ring 150, thereby improving the sealing performance and making it difficult for outside air to enter the bottle.

[0036] In some embodiments of this utility model, the housing 100 is further provided with an outlet 130, and the output end of the air extraction component 200 is connected to the outlet 130.

[0037] Specifically, the control module 400 includes an MCU or CPU and its associated circuitry. The air extraction assembly 200 typically includes an air pump motor. The input end of the air pump motor is connected to the extraction port 120 through a first fitting, and the output end of the air pump motor is connected to the discharge port 130 through a second fitting. It can be understood that the air pump motor can have a unidirectional conduction structure. After the gas is discharged from the extraction port 120 to the discharge port 130, the air pump motor can restrict the gas from flowing back from the discharge port 130 to the extraction port 120. Alternatively, the air pump motor is also connected to a one-way valve 210, which is used to restrict the gas from flowing back from the discharge port 130 to the extraction port 120.

[0038] The housing 100 is also equipped with a button 160, which is connected to the control module 400. The user can control the start and stop of the vacuum assembly 200 by pressing the button 160. The housing 100 can also be equipped with a first LED indicator and a second LED indicator. When the user presses the button 160 briefly, the first LED indicator lights up, controlling the air pump motor to start. After the vacuum is completed, the first LED indicator lights up and the second LED indicator lights up.

[0039] In some embodiments of this utility model, such as Figure 3 , 7 As shown, the current measuring and vacuuming device also includes a charging port 510, a charging module 520, and an energy storage module 530. The charging port 510 is disposed in the housing 100, and the charging module 520 and the energy storage module 530 are disposed inside the housing 100. The input terminal of the charging module 520 is connected to the charging port 510, and the output terminal of the charging module 520 is connected to the energy storage module 530. The energy storage module 530 is connected to the vacuuming assembly 200 to supply power to the vacuuming assembly 200.

[0040] The energy storage module 530 can be a conventional battery, which can be used as a power source to supply power to the vacuum assembly 200, control module 400, etc. The charging port 510 can be a USB port. The charging module 520 can include a voltage regulator chip and its auxiliary circuits. The charging module 520 modulates the electrical energy input from the USB port to form a suitable charging voltage and charging current to charge the energy storage module 530.

[0041] In some embodiments of this utility model, such as Figure 5 As shown, the current measuring and vacuuming device also includes a switching module 540. The energy storage module 530 is connected to the vacuuming assembly 200 through the switching module 540. The charging port 510 is connected to the controlled end of the switching module 540 and the output end of the switching module 540.

[0042] When the charging port 510 is connected to an external charging power source, components such as the air extraction assembly 200 and the control module 400 can be directly powered by the charging power source without the need for the energy storage module 530 to be powered. Thus, when the charging port 510 is connected to an external charging power source, the controlled end of the switching module 540 receives the charging power source connection signal and shuts off, and the charging power source directly replaces the energy storage module 530 in terms of power supply. At the same time, the charging power source can also charge the energy storage module 530.

[0043] Specifically, the switching module 540 includes a semiconductor switching transistor Q1, a resistor R8, and a diode D1. The switching transistor Q1 can be an N-type transistor, a MOSFET, a thyristor, etc. The input terminal of the switching transistor Q1 is connected to the energy storage module 530. The controlled terminal of the switching transistor Q1 is connected to the first end of the resistor R8, the charging port 510, and the positive terminal of the diode D1, respectively. The tail end of the resistor R8 is grounded. The negative terminal of the diode D1 is connected to the output terminal of the switching transistor Q1 and serves as a power supply to various electrical components.

[0044] This utility model relates to a current-measuring vacuum device. The bottle can store beverages or food. The shell 100 is connected to the bottle via a connecting structure 140. The control module 400 controls the vacuum assembly 200 to start operation, performing vacuuming treatment inside the bottle. Air in the bottle is extracted through the extraction port 120. Initially, the lower the vacuum level inside the bottle, the lower the operating current of the vacuum assembly 200 will be. As the vacuum level inside the bottle increases, the operating current of the vacuum assembly 200 will increase. The current detection module 300 detects the operating current of the vacuum assembly 200. When the operating current reaches a set current threshold, it proves that the vacuum level inside the bottle meets the user's requirements, and the control module 400 can then control the vacuum assembly 200 to stop. Maintaining a high vacuum level inside the bottle is beneficial for storing beverages or food, keeping them fresh during storage. This design reduces production costs, shrinks size, and is easy to carry.

[0045] In some embodiments of this utility model, such as Figure 6 As shown, the current measuring and vacuuming device also includes a drive module 600, which is connected to the air pump motor to form at least a partial drive branch. The drive branch is used to connect to the power supply. The control module 400 is connected to the controlled end of the drive module 600 to control the on / off state of the drive module 600.

[0046] The control module 400 can control the drive module 600 to turn on and off according to the operation command input by the button 160, thereby controlling the air pump motor to start or stop.

[0047] In some embodiments of this utility model, such as Figure 6 As shown, the drive module 600 includes a semiconductor switch Q2, a resistor R11, and a resistor R12. The input terminal of the switch Q2 is connected to the air pump motor to form at least a partial drive branch. The controlled terminal of the switch Q2 is connected to the first terminal of the resistor R11 and the first terminal of the resistor R12, respectively. The tail terminal of the resistor R12 is connected to the output terminal of the switch Q2. The tail terminal of the resistor R11 is connected to the control module 400.

[0048] In some embodiments of this utility model, such as Figure 6 As shown, the current detection module 300 includes resistor R15, resistor R13, and capacitor C12. The first end of resistor R15 is connected to the first end of resistor R13 and the end of the drive branch, respectively. The end of resistor R13 is connected to the first end of capacitor C12 and the control module 400, respectively. The end of resistor R15 and the end of capacitor C12 are both grounded. Resistor R15 serves as a sampling resistor. The operating current flows through resistor R15 and into ground, forming a terminal voltage on resistor R15. This voltage is then filtered by resistor R13 and capacitor C12 and output to the control module 400. The control module 400 can then analyze and determine the magnitude of the operating current.

[0049] To prevent beverages or food from clogging the extraction port 120 when the bottle is tilted, and to prevent the beverage or food from being discharged from the outlet 130 if the vacuum assembly 200 is activated at this time, the current-voltage measuring vacuum device further includes a tilt detection module 700 in some embodiments of this utility model. The tilt detection module 700 is used to detect tilt signals, and the control module 400 is connected to the tilt detection module 700 to control the vacuum assembly 200 to stop operating according to the tilt signal.

[0050] Specifically, the tilt detection module 700 includes a tilt detection switch S1 and a resistor R3. The first end of the resistor R3 is connected to the power supply, and the second end of the resistor R3 is connected to the first end of the tilt detection switch S1 and the control module 400. The second end of the tilt detection switch S1 is grounded. Under normal conditions, the tilt detection switch S1 is normally closed. When the bottle tilts, the contacts of the tilt detection switch S1 open, thereby generating a tilt signal output to the control module 400.

[0051] It should be noted that users can also press and hold the button for 1602 seconds (or set other time values) to enter the cleaning mode. In this mode, the control module 400 blocks the tilt signal, the bottle can be inverted, and clean water can be loaded into the bottle. The air extraction component 200 is activated to drain the clean water, thereby achieving the purpose of cleaning.
