[0028] In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present utility model, the present utility model is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0030] The embodiment of the utility model provides a control device for a vacuum juicer, which comprises at least a bottle body, a bottle cap and a vacuum pump. Fruits to be processed are placed in the bottle body. The bottle cap is buckled on the bottle body, and the vacuum pump is used to evacuate the bottle body, thereby exhausting the air in the bottle body and preventing the outside air from entering the bottle body, so that the bottle body can achieve the vacuum preservation function.

[0031] like Figure 1 As shown, the control device of this embodiment includes a controller 1 for controlling the start and stop of the vacuum pump, and a pressure detection circuit 2 and an opening and closing detection circuit 3 electrically connected to the controller 1 respectively.

[0032] The pressure detection circuit 2 is arranged at the bottle mouth of the bottle body, and the pressure detection circuit 2 is used to collect bottle pressure data in the bottle body.

[0033] The opening and closing detection circuit 3 is arranged at the position of the bottle cap. The opening and closing detection circuit 3 detects the relative position of the bottle cap and the bottle body through a position sensor element, and can generate a closing signal when the bottle cap is closed.

[0034] The position sensing element is constructed as a contact sensor or a proximity sensor, which may include a magnetic sensing element or a photoelectric sensing element.

[0035] The controller 1 of the control device of this embodiment can receive bottle pressure data of the bottle body and closing signals of the bottle body and the bottle cap to control the start and stop of the vacuum pump.

[0036] Specifically, when the vacuum juicer starts working, the opening and closing detection circuit 3 can continuously detect whether the bottle cap is closed. When the controller 1 does not receive the closing signal of the bottle cap, the vacuum juicer maintains a standby state; when the controller 1 receives the closing signal of the bottle cap, the bottle pressure data in the bottle is collected through the pressure detection circuit 2, and the relationship between the bottle pressure data and the set air pressure value can be determined to determine whether to start the vacuum pump. For example, when the bottle pressure data is greater than the set air pressure value, the controller 1 controls the vacuum pump to work; when the bottle pressure data is less than or equal to the set air pressure value, the controller 1 controls the vacuum pump to stop working, and the vacuum juicer enters a standby state. Among them, the specific size of the set air pressure value can be determined according to the specific situation.

[0037] The control device on the vacuum juicer of this embodiment includes a pressure detection circuit 2 for collecting bottle pressure data and an opening and closing detection circuit 3 capable of generating a bottle cap closing signal. The pressure detection circuit 2 and the opening and closing detection circuit 3 are respectively connected to a controller 1 of the control device, so that the controller 1 of the control device receives the bottle pressure data of the bottle body and the closing signals of the bottle body and the bottle cap to control the start and stop of the vacuum pump, thereby ensuring the vacuum degree in the bottle body and improving the preservation effect of the bottle body.

[0038] In some embodiments, the control device further includes a voltage regulating circuit 4, which is electrically connected to the power supply, the controller 1 and the pressure detection circuit 2 respectively.

[0039] The voltage regulating circuit 4 is used to adjust the voltage of the power supply to a preset power supply signal, so as to respectively supply power to the controller 1 and the pressure detection circuit 2. The power supply can be understood as an external power supply or a battery.

[0040] Specifically, the voltage regulating circuit 4 can be a step-down circuit, the input end of which is connected to the battery, and the output end is respectively connected to the controller 1 and the pressure detection circuit 2, and the step-down circuit is used to reduce the battery voltage to a suitable voltage value to power the controller 1 and the pressure detection circuit 2. The step-down circuit can reduce the battery voltage to 3.3V.

[0041] like Figure 1 and Figure 2 As shown, in some embodiments, the position sensing element includes a Hall element 30 and a magnetic member (not shown in the figure), which can be understood as a contact sensor or a proximity sensor. The Hall element 30 has a first pin, a second pin and a third pin.

[0042] Specifically, the first pin and the second pin of the Hall element 30 are electrically connected to the controller 1 respectively, the first pin of the Hall element 30 is connected to the VSS pin of the controller 1 , and the third pin of the Hall element 30 is grounded.

[0043] The first pin of the Hall element 30 is also connected to the second pin of the Hall element 30 through the first resistor 31. The second pin of the Hall element 30 is the output end of the closing signal, that is, the closing signal of the position sensor for detecting the bottle cap is transmitted to the controller 1 through the second pin of the Hall element 30.

[0044] Specifically, when the bottle cap on the vacuum juicer is not closed, the level of the second pin is pulled high by the first resistor 31; when the bottle cap on the vacuum juicer is closed, the level of the second pin of the Hall element 30 is pulled low internally, thereby sending a closing signal to the controller 1.

[0045] This embodiment uses the Hall element 30 and the magnetic element as position sensing elements, which have a long life and high reliability. Since there are no moving parts inside, there are no friction and wear problems, thereby ensuring its stability and durability.

[0046] In some embodiments, the position sensor element can periodically detect whether the bottle cap of the vacuum juicer is closed, and the detection interval is not specifically limited. When the position sensor element uses a Hall element 30 and a magnetic element, the detection time interval can be adjusted by software.

[0047] Furthermore, if Figure 1 and Figure 3 As shown, in some embodiments, the pressure detection circuit 2 includes a pressure sensor 20. The pressure sensor 20 has a first pin, a second pin, a third pin, a fourth pin and a fifth pin.

[0048] The second pin of the pressure sensor 20 is connected to the controller 1 to transmit a clock signal, and the third pin of the pressure sensor 20 is connected to the controller 1 to transmit bottle pressure data.

[0049] The second pin of the pressure sensor 20 is also connected to the voltage regulating circuit 4 through a second resistor 22 , and the third pin of the pressure sensor 20 is also connected to the voltage regulating circuit 4 through a third resistor 23 .

[0050] Specifically, the second pin of the pressure sensor 20 of this embodiment can be connected to the corresponding SCL pin on the controller 1 via SCL (Serial Clock line), and the third pin of the pressure sensor 20 can be connected to the corresponding SDA pin on the controller 1 via SDA (Serial Data line).

[0051] In some embodiments, the first pin and the fifth pin of the pressure sensor 20 are connected through the first capacitor 21, the first pin of the pressure sensor 20 is also grounded, and the fifth pin of the pressure sensor 20 is also electrically connected to the voltage regulating circuit 4. The fourth pin of the pressure sensor 20 is not connected to anything, and when the pressure detection circuit 2 is working, the pressure sensor 20 continuously detects and collects the bottle pressure data in the bottle body. Among them, the accuracy of the bottle pressure data can be adjusted by the first capacitor 21, and the signal output by the pressure sensor 20 can be filtered by the first capacitor 21 to improve the accuracy of the signal.

[0052] In some embodiments, the bottle cap on the vacuum juicer includes a main cap and a flip cover rotatably connected to the main cap. The main cap is threadedly connected to the bottle mouth of the bottle body. The main cap may be provided with a cover hole, and the flip cover can rotate relative to the main cap to close or open the cover hole.

[0053] The Hall element 30 in the position sensor of this embodiment can be arranged on the main cover, and the magnetic element can be arranged on the flip cover. When the flip cover rotates relative to the main cover to close the cover hole, the Hall element 30 can sense the magnetic field of the magnetic element on the flip cover, thereby generating a closing signal.

[0054] The Hall element 30 is arranged on the main cover and the magnetic element is arranged on the flip cover, so that the accuracy of bottle cap closure detection can be improved.

[0055] The pressure detection circuit 2 of this embodiment is arranged at the bottle mouth of the bottle body, and its position is not specifically limited, as long as it can detect the bottle pressure data of the bottle body.

[0056] When the bottle cap includes a main cap and a flip cap rotatably connected to the main cap, the pressure detection circuit 2 is directly arranged on the main cap and located on a side of the main cap facing the inside of the bottle body, so as to conveniently detect the bottle pressure data of the bottle body.

[0057] Preferably, in this embodiment, a circuit board may be adhered or fixed on the side of the main cover facing the bottle body, and the pressure sensor 20 is arranged on the circuit board.

[0058] The embodiment of the utility model further provides a vacuum juicer, which includes a control device for a vacuum juicer as described in any one of the above embodiments.
