Description

Technical Field

[0001] The present invention relates to the technical field of aromatherapy machines, and particularly to a double-bottle aromatherapy machine. Background Art

[0002] An aromatherapy machine atomizes water and pure plant essential oils in various ways to keep the environment such as a living room or a car interior at a relatively high humidity, generate a certain amount of natural negative oxygen ions, purify the air, and achieve the effect of aromatherapy at the same time. It can assist in treating and relieving diseases such as influenza, hypertension, and tracheitis, and play a certain protective role in the nervous system, cardiovascular system, and human metabolism.

[0003] The internal gas of the aromatherapy machine flows in the air flow channel, and air flow holes are provided in the air flow channel to control the opening and closing of the channel, thereby controlling the aroma delivery. The control of the air flow channel of the existing aromatherapy machine is mainly controlled by the power source of the air flow. For example, the air flow is controlled by the fan power, and it is mainly applicable to the control of a single air flow channel, and cannot adapt to the opening and closing control of the double air flow channels and the adjustment of the fragrance concentration. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a double-bottle aromatherapy machine, which can at least solve the problem that the existing aromatherapy machine cannot adapt to the on-off control and concentration adjustment of the aroma in the double air flow channels, and has the advantages of simple and ingenious structure and convenient use.

[0006] (2) Technical Solutions

[0007] To achieve the above purpose, the present invention provides the following technical solutions:

[0008] A double-bottle aromatherapy machine includes a housing and an air flow control mechanism arranged in the housing; two independent air flow channels are formed in the housing, and a first air flow hole, an aroma chamber, and a second air flow hole are sequentially arranged in each air flow channel. The aroma chamber is connected to an essential oil bottle, and a fan for guiding the air flow is also arranged in the housing. The air flow control mechanism is used to simultaneously control the opening and closing of the two air flow channels.

[0009] Further setting: The housing includes a front cover, a rear cover and an air duct cover. The front cover and the rear cover are covered with each other. The front cover includes two mounting openings for placing perfume bottles. Inside the front cover, two aroma chambers and two blower chambers for mounting the blowers are sequentially formed by rib plates. The first air holes are arranged between the blower chamber and the aroma chamber on the same side. The aroma chamber and the mounting opening on the same side are communicated with each other. The second air holes are arranged at one end of the aroma chamber away from the first air holes. The front cover is further provided with an air outlet chamber communicated with the second air holes. The air outlet chamber is provided with air outlet holes. The air duct cover is hermetically covered on the upper ends of the rib plates of the front cover and forms the air flow channel with the blower chamber, the aroma chamber and the air outlet chamber.

[0010] With such a setting, the front cover of the outer shell forms a blower chamber, an aroma chamber and an air outlet chamber through rib plates, and forms a complete air duct through the covering of the air duct cover. The air flow enters the aroma chamber from the blower chamber through the first air holes. The aroma of the perfume bottle enters the aroma chamber from the mounting opening and enters the air outlet chamber with the air flow through the second air holes, and finally is discharged outwards through the air outlet holes of the air outlet chamber, achieving the effect of aromatherapy.

[0011] Further setting: The air flow control mechanism includes a motor, a lead screw connected to the output shaft of the motor, a nut slider threadedly connected to the lead screw, a slide rail for restricting the sliding direction of the nut slider, a cross bar connected to the nut slider, a pressing rod arranged at one end of the cross bar, and a pull rod arranged at the other end of the cross bar. Sealing members for controlling the opening and closing of the first air holes and the second air holes are arranged on the pull rod and the pressing rod. The nut slider drives the cross bar to drive the pressing rod and the pull rod to move in the opening and closing directions of the air holes of the sealing members. The pressing rod and the pull rod are connected with a spring, and the spring drives the pressing rod and the pull rod to move in the closing direction of the air holes of the sealing members.

[0012] With such a setting, when the air flow control mechanism works, the motor drives the lead screw to rotate. The rotation of the lead screw drives the nut slider to move along the lead screw direction. The cross bar moves synchronously with the nut slider, driving the pressing rod and the pull rod to move in the opening and closing directions of the air holes by the sealing members, realizing the opening and closing control of the air holes.

[0013] Further setting: The spring is sleeved outside the pressing rod and the pull rod. Limiting parts for restricting the movement of the spring are further arranged on the pressing rod and the pull rod. A pressing plate is arranged at one end of the cross bar close to the pressing rod. The pressing rod is arranged opposite to the pressing plate. A sliding hole is arranged at one end of the cross bar close to the pull rod. The pull rod is slidably arranged in the sliding hole and is provided with a large head part on the side away from the sealing member to prevent the pull rod from sliding out of the sliding hole.

[0014] With such a setting, the pressing action of the cross bar on the pressing rod and the pulling action on the pull rod will not interfere with each other, and the control effect of opening and closing of the two air flow channels can be achieved.

[0015] Further setting: The pull rod and the pressure rod are symmetrically arranged on both sides of the nut slider.

[0016] With such setting, the overall structure is symmetric and the force is more reasonable.

[0017] Further setting: The lead screw is connected to the auxiliary lead screw through a gear transmission. The auxiliary lead screw is arranged parallel to the lead screw and rotates in the opposite direction. The nut slider includes a first nut slider connected to the lead screw and a second nut slider connected to the auxiliary lead screw. The second nut slider extends towards the first nut slider to form a clamping block. A clamping groove cooperating with the clamping block is provided on the first nut slider. A control button for controlling the movement of the clamping block towards the clamping groove is further provided on the second nut slider. The screw hole of the second nut slider includes a mating section and a disengaging section provided at the upper end of the mating section. The mating section is provided with a thread adapted to the auxiliary lead screw. The disengaging section is slidably engaged with the auxiliary lead screw. When the clamping block is engaged with the clamping groove, the auxiliary lead screw is arranged in the disengaging section, and the first nut slider and the second nut slider move synchronously along the direction of the lead screw. When the clamping block is disengaged from the clamping groove, the auxiliary lead screw is threadedly engaged with the mating section of the screw hole, and the first nut slider and the second nut slider move in opposite directions.

[0018] With such setting, when it is necessary to control the two air flow channels to transport fragrance simultaneously, the clamping block of the second nut slider is pulled out from the clamping groove of the first nut slider through the control button, and the auxiliary lead screw is threadedly connected to the mating section of the screw hole of the second nut slider. When the motor drives the lead screw to drive the first nut slider to move, the auxiliary lead screw drives the second nut slider to move in the opposite direction, so as to press and pull the pressure rod and the pull rod respectively through the cross bar, and at the same time control the seals in the two air flow channels to open the air holes, so that the two air flow channels transport fragrance outwards simultaneously.

[0019] Further setting: The clamping groove and the clamping block are respectively arranged at the tops of the first nut slider and the second nut slider.

[0020] With such setting, it is convenient to control the action of the clamping block through the control button.

[0021] Further setting: A rubber strip is provided between the disengaging section and the mating section of the screw hole of the second nut slider, and the distance between the rubber strips is smaller than the outer diameter of the auxiliary lead screw.

[0022] With such setting, the rubber strip separates the mating section and the disengaging section and forms two working spaces, avoiding the up and down shaking of the nut slider and affecting the normal mating work.

[0023] (III) Beneficial effects

[0024] By adopting the above technical solutions, compared with the prior art, the present invention has the following advantages:

[0025] The overall structure of the double-bottle aromatherapy machine provided by the present invention is simple and ingenious. It controls the switches of two air flow channels by a single motor, and can achieve three modes: one open and one closed, both closed, and both open for the two air flow channels, adapting to the selection and adjustment of different perfume odors and aroma concentrations, with strong applicability and well meeting people's daily use requirements for aromatherapy machines.
