Specific embodiments

[0036] The present utility model will be further described below in conjunction with the drawings and embodiments:

[0037] Embodiment 1: Refer to Figures 1 to 7 As shown, an adjustable aromatherapy machine includes a tank body 1, an acceleration mechanism 2 and an upper cover 3. The upper cover 3 is connected to the top of the tank body 1 through the acceleration mechanism 2.

[0038] A chamber 4 communicating with the top of the tank body 1 is provided inside the tank body 1.

[0039] The acceleration mechanism 2 is detachably installed on the top of the tank body 1. The acceleration mechanism 2 includes a shell 5, a fan assembly, a power supply unit for supplying power to the fan assembly, and a control unit for controlling the operation of the fan assembly. The fan assembly is arranged inside the shell 5. The power supply unit is arranged inside the shell 5 and / or on the side wall of the shell. One side of the control unit is arranged on the outer side wall of the shell 5. The shell 5 is detachably installed on the top of the tank body 1, and the top of the shell 5 is communicated with the chamber 4.

[0040] The upper cover 3 is detachably installed on the top of the shell 5, and the upper cover 3 has a first hollow structure 6. The first hollow structure 6 communicates the chamber 4 with the outside of the upper cover 3.

[0041] In the present utility model, the required deodorant or aromatherapy substance, such as deodorant, aromatherapy liquid, aromatherapy paste, etc., will be placed in the chamber of the tank body. In this embodiment, taking the placement of aromatherapy paste in the tank body as an example, when it is not used initially, a plug can be set on the inner side of the top of the tank body to prevent the evaporation and dispersion of the internal aromatherapy paste. Of course, a seal can also be set on the first hollow structure of the upper cover to block it to prevent the evaporation of the internal aromatherapy paste. When it is needed to use, the plug or the seal is removed. At this time, the outside of the upper cover is communicated with the chamber, and the aromatherapy paste has a channel for evaporating and dispersing outward. At this time, the evaporation speed may be relatively slow. In order to accelerate the evaporation of the aromatherapy paste, the operator directly controls the operation of the fan assembly through the control unit (the power supply unit supplies power to the fan assembly so that the fan assembly can work normally), and uses the fan assembly to accelerate the air flow rate in the chamber, thereby improving the evaporation speed of the internal aromatherapy paste, making the internal fragrance quickly flow from the first hollow structure of the upper cover to the outside, and improving the deodorization and aromatherapy efficiency and effect.

[0042] Wherein, the inner bottom of the housing 5 is screwed to the outer top of the tank body 1, and the inner bottom of the upper cover 3 is screwed to the outer top of the housing 5. After the aromatherapy paste in the tank body is used up, the tank body can be opened to add aromatherapy paste or other deodorizing objects or other objects.

[0043] Wherein, in this embodiment, the upper cover has a plurality of holes for communicating the top surface and the bottom surface of the upper cover, and the plurality of holes constitute the first hollow structure. The holes can be round holes, strip holes or other shapes.

[0044] Wherein, the housing 5 has a cavity penetrating through both ends inside, and the cavity is communicated with the chamber 4, and the fan assembly and the power supply unit are arranged in the cavity. When the aromatherapy paste in the chamber evaporates, it can evaporate and disperse through the cavity from the first hollow structure of the upper cover. At the same time, when the fan assembly and the power supply unit are in the cavity of the housing, the fan assembly and the power supply unit can be hidden, and it does not affect the air circulation inside the chamber of the tank body and the outside.

[0045] See Figure 5 、 6 As shown, a partition 7 with a hollow structure is provided in the middle of the cavity, and the fan assembly and the power supply unit are installed on the partition. The partition is provided for the installation of the fan assembly and the power supply unit. At the same time, the partition is of a hollow structure and does not affect the air flow above and below the partition, so that when the aromatherapy paste in the chamber evaporates, it can enter the upper cover through the hollow partition and leak out from the first hollow structure of the upper cover.

[0046] See Figure 5 、 6 As shown, the fan assembly includes a fan blade 8 and a motor 9. The motor 9 is installed on the partition 7, the fan blade 8 is connected to the output shaft of the motor 9, and the motor 9 is configured to drive the fan blade 8 to rotate.

[0047] Wherein, the motor drives the fan blade to rotate. When the fan blade rotates, it can improve the air flow inside the chamber, thereby accelerating the evaporation of the internal aromatherapy paste (or other deodorants, etc.), and improving the deodorizing and aromatherapy efficiency and effect. Among them, the power supply unit supplies power to the motor, and the control unit is used to control the operation of the motor and can also control the rotation speed of the motor, thereby adjusting the rotation speed of the fan blade and adjusting the evaporation efficiency of the internal aromatherapy paste.

[0048] See Figure 5 、 6As shown, the partition 7 divides the cavity into an upper cavity 10 and a lower cavity 11, and the upper cavity 10 and the lower cavity 11 are communicated through the hollow partition; wherein, there are a plurality of holes on the partition for communicating the upper cavity and the lower cavity. The holes can be circular holes, or strip-shaped holes, or holes of other shapes to achieve the communication between the upper cavity and the lower cavity.

[0049] The fan blade 8 is arranged in the lower cavity 11. An installation cylinder 12 with an open top is arranged on the partition 7. The bottom of the motor 9 is installed in the installation cylinder 12, and the output shaft of the motor 9 passes through the bottom of the installation cylinder 12 and is connected to the fan blade 8.

[0050] The inner surface of the installation cylinder 12 matches the outer surface of the motor 9. At least two limiting members 13 extending upward are annularly arranged at the top of the installation cylinder 12, and the limiting members 13 limit the upward movement of the motor 9;

[0051] The limiting member is a buckle, and the inner end of the top of the buckle abuts against the top surface of the motor. Preferably, there are two buckles, which are symmetrically arranged on both sides of the installation cylinder.

[0052] In this embodiment, the housing, the partition and the limiting member are preferably made of plastic, or only the limiting member is made of plastic, which has a certain elastic deformation ability. In this way, when the motor is installed, the bottom of the motor moves towards the installation cylinder. During this process, the buckle is squeezed, causing the buckle to deform outward a little bit, so that the motor can pass through the buckle. When the bottom of the motor completely enters the installation cylinder, its top also completely passes through the buckle, and the buckle elastically deforms and resets, so that the inner end of the top of the buckle abuts against the top surface of the motor, thereby being able to limit the upward movement of the motor and prevent it from detaching from the installation cylinder. At the same time, if the motor needs to be disassembled, use a tool to swing the buckle outward and deform it a little bit to release the upward movement limit of the motor, and then the motor can be moved upward to detach from the installation cylinder.

[0053] See Figure 1 、 2 As shown in FIGS. 5 and 6, the control unit includes a control circuit board 14 and a control switch 15. The control circuit board 14 is arranged in the housing 5. The control circuit board 14 is electrically connected to the fan assembly and the power supply unit, the control switch 15 is electrically connected to the control circuit board 14, and the control switch 15 is arranged on the outer side wall of the housing 5.

[0054] In this embodiment, the motor is electrically connected to the control circuit board. The control switch is directly arranged on the outer side wall of the housing. During use, the user directly presses the control switch, and the data can be fed back to the control circuit board. The control circuit board controls the motor to work, thereby driving the fan blade to rotate and accelerating the air flow. The control switch can have multiple gears for adjusting the rotation speed of the motor, so as to adjust the fan speed and the air flow speed inside the chamber.

[0055] Wherein, a lighting component (not shown in the figure) is further arranged on the tank body 1. The lighting component is electrically connected to the power supply unit and the control circuit board. The power supply unit supplies power to the lighting component. A lighting component control switch 16 for controlling the operation of the lighting component is further arranged on the outer side wall of the housing 5.

[0056] The lighting component can adopt LED lamp beads. The LED lamp beads can be directly embedded inside the tank body, or on the outer wall of the tank body, or inside the chamber. The lighting component control switch is electrically connected to the control circuit board. During use, by controlling the lighting component control switch, the lighting component can be turned on or off, so as to realize the lighting or turning off of the tank body. When the lighting component emits light, it can enhance its aesthetic feeling and also play a role in lighting.

[0057] Meanwhile, with the arrangement of the lighting component, when the motor drives the fan blade to rotate at different gear speeds, the lighting component can emit light of different colors or different intensities to distinguish the gears of the motor.

[0058] See Figure 1 、 2 As shown in FIGS. 4, 5, and 6, the power supply unit includes a battery and / or a USB power supply interface 17. In the present utility model, the power supply unit can be a battery or a USB power supply interface, or a combination of a battery and a USB power supply interface. In this embodiment, the power supply unit includes a combination of a battery and a USB power supply interface.

[0059] Wherein, a battery compartment 18 is arranged inside the housing 5. The battery is detachably installed in the battery compartment 18. The battery compartment 18 is installed on the partition plate 7 and is arranged beside the fan assembly. The battery compartment 18 is used for installing the battery. The USB power supply interface 17 is arranged on the outer side wall of the housing. For the USB power supply interface, an external power supply can be connected to the fan assembly and the lighting component through a USB line and the USB power supply interface to supply power.

[0060] See Figure 7As shown in the figure, it is the control circuit diagram of an adjustable aromatherapy machine. The battery, the USB power supply interface, and the MCU control unit are connected. The USB power supply interface is connected to the MCU control unit through overvoltage and overcurrent protection devices. When in use, when there is power supply at the USB power supply interface, the USB power supply interface will pass through an overvoltage and overcurrent protection device. When the external voltage is too high or the current is too large, the main board cuts off the USB circuit to prevent the components on the control circuit board from being damaged, playing a role in protecting the control circuit board. There is a USB detection circuit on the control circuit board. When the USB is inserted, the battery power supply circuit will be completely disconnected. At this time, only the USB power supply is available. When the USB is unplugged, it automatically switches back to battery power supply. There is a battery reverse connection prevention circuit on the control circuit board. When the positive and negative poles of the battery are installed reversely, the battery power supply circuit will automatically disconnect to prevent excessive current from damaging the components on the control circuit board.

[0061] At the same time, there is a battery boost circuit on the control circuit board. Because the voltage of the battery will decrease during use, in order to keep the motor speed stable, a boost chip is set on the control circuit board so that when the battery supplies power, the power supply voltage of the motor is guaranteed to be about 3V. Among them, the circuit has three gears, and each gear corresponds to three different motor speeds. The control of the speed is achieved by the single-chip microcomputer (MUC control unit) outputting different duty cycles to the N-MOS control device to control the switching time of the MOS, so as to achieve different speeds corresponding to the three gears. Each gear corresponds to a different mixed-color light (the light-emitting component can be provided with multiple lamp beads, and the lamp beads respond simultaneously during the working process of the lamp beads and the motor, serving as the mixed-color light corresponding to different gears of the motor. There are also lamp beads controlled by the switch of the light-emitting component, playing the role of lighting and beautification).
