Detailed Description

The following describes the detailed implementation of the embodiments of the present utility model with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the utility model, are not intended to limit the utility model.

Fig. 1 shows a schematic block diagram of an air cleaning apparatus, as shown in fig. 1, including: a housing 1, and a power module 2, a control module 3 and a negative ion module 4 which are arranged in the housing; the control module 3 is electrically connected with the power module 2 and the negative ion module 4 respectively to obtain power supply of the power module 2 and send a control instruction to the negative ion module 4; wherein, the negative ion module 4 receives the control instruction to generate and release negative ions.

For example, for the power module 2, in view of the need to reduce the volume and to make the cruising convenient, the air cleaning device of the present utility model preferably employs a rechargeable battery, such as a lithium battery or the like. Compared with a detachable battery, the detachable battery can be repeatedly used for the battery for a plurality of times, so that the cost is reduced, the pollution of the battery to the outside is reduced, and a corresponding battery box is not required to be arranged on the other hand, the space of the shell is saved, and the air purifying device is further smaller.

The control module 3 obtains the electric energy required by operation from the power module 1, and controls the negative ion module 4 to operate, so that the negative ion module 4 can release a large amount of negative ions to purify the air.

Compared with the existing passive purification mode, the air purification device provided by the utility model adopts an active purification mode, and can purify air anytime and anywhere by utilizing negative ions generated by the air purification device.

Further details of the air cleaning device are described below with reference to the accompanying drawings.

In a preferred embodiment, as shown in fig. 2, the control module 3 includes an instruction generating unit 31 for generating corresponding control instructions according to user operations; and a driving unit 32 electrically connected to the instruction generating unit 31 and the negative ion module 4, for controlling the operation of the negative ion module 4 based on the control instruction.

For example, the control instruction generated by the instruction generating unit 31 is a PWM pulse signal having a certain frequency. The driving unit 32 can adopt a field effect transistor, and is conducted based on the action of the pulse signal so as to drive the negative ion module to operate.

In a preferred embodiment, as shown in fig. 2, the negative ion module 4 includes a high-pressure unit 41 (negative ion generator in fig. 2) and a release unit 42 having one end connected to the high-pressure unit 41 and the other end placed in the air; wherein the high voltage unit 41 supplies a negative high voltage to the release unit 42 so that the release unit 42 releases electrons into the air to form the negative ions.

For example, the high voltage unit 41 is also called a high voltage package or a negative ion generator, and a boost circuit is provided inside the high voltage unit, which can generate a low voltage to a negative high voltage of a certain value, for example, to a negative high voltage of-2.5 KV. The discharge unit 42 may be a discharge tip of a metal or a carbon element material, and generates a high corona using a high voltage of a tip direct current, thereby discharging a large amount of electrons at a high speed. Because electrons cannot stay in the air for a long time and can be immediately captured by oxygen molecules in the air, air anions are generated.

Specifically, as shown in fig. 2, the power module 2 is powered by a lithium battery (Lion-4.2V). In the control module 3, the instruction generating unit 31 mainly adopts an NE555 chip to generate a pulse signal, and the driving unit 32 adopts an AP2305 to drive the negative ion module to operate. A switch S1 is provided between the control module 3 and the power module 2, and when the switch S1 is turned on, the power module 2 is disconnected from the control module 3, and the power module 2 stops supplying power to the control module 3; when the switch S1 is closed, the power module 2 is communicated with the control module 3, and the power module 2 starts to supply power to the control module 3. The release unit 32 employs a carbon fiber brush.

Specifically, when the switch S1 is turned off, the lithium battery (BT 1) is connected to the NE555 (U1) and supplies power to the NE555 (U1) chip, so that the NE555 (U1) chip operates to output a PWM pulse signal with a fixed frequency. Then, the AP2305 (Q2) is turned on by the pulse signal, and drives the high voltage unit 41 (the negative ion generator in fig. 2) to operate, so that the high voltage unit 41 (the negative ion generator in fig. 2) generates a low voltage to a negative high voltage of-2.5 KV or more through the voltage boosting circuit. Finally, a high corona is generated by the tip of the release unit 42 (carbon fiber brush in fig. 2), and a large amount of negative ions are released to purify the air.

In a preferred embodiment, as shown in fig. 2, the air cleaning apparatus further includes a charging management module 5 connected to the power module 2 for performing charging management on the power module 2.

For example, in the process of charging the power module, the power module may be damaged to some extent due to unstable charging current and voltage, so that the charging process has a certain safety risk and the service life of the power module is reduced. Therefore, the air purifying device is provided with the charging management module, can monitor the change of the charging voltage in real time in the process of charging the power supply module, and can monitor and manage the whole charging process of the power supply module.

According to the embodiment, the air purifying device is provided with the corresponding charging management module, and can monitor and manage the charging process of the power supply module in real time, so that the charging safety of the power supply module is ensured, and the electric quantity of the power supply module can realize ultra-long endurance.

In a preferred embodiment, as shown in fig. 2, the charge management module 5 includes: an interface unit 51 provided on the housing for accessing an external power source; and a conversion unit 52 electrically connected to the interface unit 51 for converting a charging current supplied from the external power source into a charging current suitable for the power module 2.

Preferably, the interface unit includes one or more of a Micro USB interface, a Type-C interface, a lighting interface, and a Mini USB interface.

For example, the interface unit preferably adopts a Micro USB interface, which has a smaller volume compared to other interfaces, and can further provide a housing space, so that the air purifying device has a smaller volume.

The above-mentioned external charging current refers to a current of an external charger. The conversion unit may convert the external charging current into a fixed charging current suitable for a power module (e.g., a lithium battery). In particular, it is necessary for the configuration of the conversion unit to consider characteristic properties of the power supply module, such as the voltage of the power supply module. Taking a power module as a lithium battery as an example, the voltage attribute of the lithium battery needs to be considered. For example, the voltage of the lithium battery varies between 3.0V and 4.2V, that is, the limiting voltage of the two ends of the lithium battery is 4.2V, and the limiting discharge voltage of the lithium battery is not lower than 3.0V. In other words, when the lithium battery is charged in the external receiving charging circuit, the charging voltage thereof cannot be higher than 4.2V; while lithium batteries provide power to external loads, the last consumed voltage stays at 3.0V. However, the existing commonly used chargers are chargers with 5V/1A or 5V/2A specifications, and the charging voltage output by the chargers to the outside is 5V, which obviously exceeds the maximum bearing voltage of the lithium battery by 4.2V. Therefore, the conversion unit in the utility model needs to configure a corresponding power management chip for the lithium battery so as to fix the charging voltage of the lithium battery at 4.2V and realize the charging management of the lithium battery.

As shown in fig. 2, the interface unit 51 adopts a Micro-USB interface, and the conversion unit 52 adopts a TP4054 power management chip. The Micro-USB interface can be connected with an external charger and is used for accessing 5V voltage. Pin4 of TP4054 (U2) VCC is a power input terminal, and is also a charging input interface of lithium battery (BT 1), which is connected with Pin1 Pin VBUS of Micro-USB (CON 1) for inputting 5V voltage. Because the voltage working range of Pin4 Pin VCC of TP4054 (U2) is 4.5V-6.5V, the output voltage of the charger of 5V/1A or 5V/2A is effectively satisfied. Pin3 of TP4054 (U2) is the charge output terminal, which is directly connected to the positive electrode of lithium battery (BT 1), and since the charge voltage output by Pin BAT is 4.2V, the voltage which can be born by lithium battery (BT 1) is just satisfied.

It should be noted that the present utility model is not limited to the TP4054 power management chip, and those skilled in the art may use a corresponding power management chip for the actual model and voltage characteristics of the power module, so as to effectively manage the charging process of the power module.

In the above embodiment, the stability of the charging current and voltage in the charging process can be ensured by configuring the conversion unit, so that the safety and reliability of charging are improved, and the endurance of the air purification device is further improved.

In a preferred embodiment, as shown in fig. 2, the air cleaning apparatus further includes: and the display module 6 is used for displaying the charging state of the power supply module 2.

Preferably, the display module includes any one of a light emitting diode, a vacuum fluorescent tube, and a cathode ray tube.

For example, as shown in fig. 2, the display module 6 includes light emitting diodes D1 and D2. D1 is a green light emitting diode, and D2 is a red light emitting diode. D2 is connected with the positive electrode of the lithium battery (BT 1) and Pin1 Pin CHRG of the TP4054 (U2) chip, respectively. When the lithium battery is being charged, the D2 red led is lit, indicating that the lithium battery is being charged. The D1 green led lights up (at this time the D2 red led goes off) after the lithium battery is fully charged. In addition, the utility model can also display whether the air purifying device works or not by utilizing the display module according to actual needs. For example, when the green led D2 blinks, it means that the air purification device is in operation, and when the green led D2 is turned off, it means that the air purification device is out of operation.

In this embodiment, through being configured with display module, can in time remind the user to power module's state of charge, ensure that power module can not appear the condition of overcharging, and then improve power module's security.

In a preferred embodiment, as shown in fig. 3, the air cleaning device further comprises a hanging member 7, one end of which is connected to the outer surface of the housing 1, and the other end of which is in a suspendable state.

For example, one end of the hanging member 7 can be fixed on the housing 1, and can be detachably connected with a fixing member arranged on the housing 1, and the other end of the hanging member can be hung on an external object, so that the air purifying device can release negative ions in a certain space around the object. For example, the utility model can be worn on the neck of a human body, and about 2 ten thousand anions per cubic centimeter are released in the air 15cm away from the carbon fiber brush position to blow to the mouth and nose of the human body.

In this embodiment, through setting up the pendant can make air purification device adhere to on external object with modes such as fixed, hang, portable for a long time. Especially when worn on human body, it can enhance immunity, improve myocardial function, improve sleep and promote metabolism. Or when hung in a room or a car, for example, formaldehyde can be deeply decomposed, peculiar smell can be removed, and air can be freshened.

Preferably, the hanging piece is a conductive hanging rope.

For example, the hanging piece can be a conductive hanging rope made of graphene material, and the wire diameter of the hanging piece is set to be 5mm. One end of the conductive hanging rope can be connected with the grounding end of the internal circuit, when the conductive hanging rope is worn on a human body, static electricity generated by the human body can be released into the ground through the conductive hanging rope, and then the effect of eliminating the static electricity of the human body can be achieved.

In this embodiment, the air purification device can effectually eliminate the static that the external object produced through the rope of can electrically conductive formula string, avoids static to the injury that external object led to the fact.

In summary, the air purifying device provided by the utility model has the following advantages:

1) An active purification mode is adopted, and an external power supply is not needed in the use process;

2) The volume is small, the portable air purifier can be carried around, and can purify air in a close fit at any time and any place;
