Description

Technical Field

[0001] This utility model belongs to the technical field of smoke aromatherapy devices, and in particular relates to a smoke aromatherapy device that is easy to replace the fragrance cartridges. Background Technology

[0002] In the prior art, there exists a type of aromatherapy device that retains its aesthetic appeal. Its airflow deflector is located inside the outermost transparent casing, while the aroma cartridge assembly (or atomizing device) is housed inside the deflector. This design facilitates airflow communication between the aroma cartridge assembly and the internal fan of the deflector (see, for example, patent applications CN202322177452.4 and CN202421750679.1).

[0003] However, when the fragrance oil in the scent cartridge is depleted and a different scent needs to be changed, the entire scent cartridge assembly usually needs to be replaced to avoid fragrance crosstalk. Because the scent cartridge assembly is located inside the diffuser, which in turn is inside the transparent housing, this nested structure results in its deep placement. Therefore, replacing the scent cartridge assembly is extremely inconvenient for users, presenting a significant drawback. Utility Model Content

[0004] To address the shortcomings of existing technologies, a smoke aromatherapy device is provided that allows for easy replacement of the aroma cartridge components.

[0005] This utility model is achieved by the following technical solution: a smoke diffuser device that facilitates the replacement of fragrance cartridges, comprising:

[0006] Base;

[0007] A visual enclosure, which is mounted on the base;

[0008] A flow guide is provided on a base and located inside a visible housing. The flow guide has an upwardly raised part at the center and an upwardly opening receiving groove at the raised part. A fan is located inside the flow guide, and the air outlet of the fan is connected to the receiving groove.

[0009] The fragrance cartridge assembly is detachably installed in the receiving slot;

[0010] The top cover is located on top of the visibility housing. The top cover is annular and surrounds the circumferential side of the raised portion. There is an annular gap between the outer wall of the raised portion and the top cover to allow smoke to flow downwards to the lower end of the guide hood.

[0011] A cover plate is located at the center of the top cover and covers the opening of the receiving groove. The cover plate is magnetically fixed to the top cover. The lower end of the cover plate is provided with a guide cavity for guiding smoke to the annular gap.

[0012] When it's time to replace the scent cartridge, simply remove the cover from the top cover. The scent cartridge will be exposed on the outside, allowing you to easily remove and replace it. After replacing the scent cartridge, place the cover in the center of the top cover. The cover will then magnetically attach to the top cover, covering the scent cartridge again.

[0013] The incense stick assembly can be any existing incense stick assembly that can generate smoke through electric heating.

[0014] This solution optimizes the position of the fragrance cartridge component, so that when the cover is not closed, the upper part of the fragrance cartridge component is exposed for easy access by the user. At the same time, the cover and the top cover are magnetically fixed, making it very convenient to remove the cover.

[0015] Preferably, the top cover is provided with a plurality of vertically extending first contact pins, the cover plate is provided with a button, the lower end of the button is exposed at the bottom of the cover plate and is used to abut against the first contact pins, and a circumferential positioning structure is provided between the cover plate and the top cover, the positioning structure including a vertically extending positioning hole and a positioning protrusion extending into the positioning hole.

[0016] When the positioning protrusion engages with the positioning hole, it achieves circumferential positioning of the cover plate and the top cover, so that the button is located exactly above the first contact pin and abuts against the first contact pin.

[0017] The positioning structure described above allows users to easily position the cover plate circumferentially when placing it, thus ensuring that the button can contact the first contact pin.

[0018] Preferably, the top cover is provided with a plurality of lamp heads that correspond one-to-one with the buttons. The lamp heads are exposed on the upper surface of the top cover and also constitute the positioning protrusions.

[0019] The button includes a pressing part located at the top of the cover plate, and the positioning hole extends upward to directly below the pressing part, so that the lamp head illuminates the pressing part after being inserted into the positioning hole;

[0020] The button includes an electronic component for contacting the first stylus. The electronic component includes a vertically extending vertical segment and a sheet-like portion located at the top of the vertical segment. The sheet-like portion is installed within the pressing part.

[0021] The lamp head not only illuminates the pressing part but also positions the top cover and the cover plate. Illuminating the pressing part makes it easier for the user to press it. When the electronic components are pressed, they transmit information to the first contact pin, thereby changing the mode of the entire smoke and aromatherapy device.

[0022] Preferably, the cover plate includes an upper cover plate and a lower cover plate. The lower cover plate covers the opening of the receiving groove and directly covers the fragrance ball assembly. There is a hollow flow guide cavity between the upper cover plate and the lower cover plate. The circumferential edge region of the flow guide cavity communicates with the annular gap. The center of the lower cover plate is provided with a mating hole that communicates with the outlet of the fragrance ball assembly. The mating hole communicates with the flow guide cavity.

[0023] The flow channel can better guide the flow of aromatherapy smoke, making it easier for the smoke to flow into the annular gap.

[0024] Preferably, the upper cover plate and the lower cover plate are coaxially arranged, and the flow guiding cavity is located at the center of the upper cover plate and the lower cover plate. The end faces of the circumferential edge regions of the upper cover plate and the lower cover plate are in contact with each other and sealed together.

[0025] Smoke leakage can be prevented by sealing the circumferential areas of the upper and lower cover plates. The sealing method can be glue bonding or fixing the two cover plates with screws, etc.

[0026] Preferably, a smoke leakage prevention structure is provided between the top cover and the cover plate;

[0027] The smoke leakage prevention structure includes an annular groove extending in the axial direction and an annular protrusion inserted into the annular groove; or

[0028] The smoke leak prevention structure includes a sealing ring placed between the two.

[0029] The above design prevents smoke from overflowing from the cover plate, wherein the annular groove and the annular protrusion are respectively provided on one of the top cover and the cover plate.

[0030] Preferably, the top of the visualization cover is provided with a clearance groove to avoid the top cover, and a connection structure for fixing the top cover is provided between the top cover and the groove wall. There is a non-contact area between the inner wall of the clearance groove and the outer wall of the top cover to form a mist exhaust gap, which is used to exhaust internal smoke to the outside; or

[0031] The top of the visual enclosure is provided with a clearance groove to avoid the top cover. The inner circumferential wall of the top cover and the raised part are provided with a connection structure to fix the top cover in the clearance groove. The outer circumferential wall of the top cover does not contact the groove wall of the clearance groove to form a mist exhaust gap. The mist exhaust gap is used to exhaust the internal smoke to the outside.

[0032] Both of the above-described solutions can secure the top cover, and a mist-expelling gap exists between the top cover and the wall of the clearance groove, facilitating smoke exhaust and improving the viewing experience. Even when a connecting structure is provided between the top cover and the raised section, the annular gap still exists, with only a small obstruction, but this has virtually no impact on smoke flow.

[0033] Preferably, the upper end of the top cover is a plate made of magnetic material, the plate is recessed with an upward-opening mating groove, the cover plate is adapted to fit into the mating groove, and a number of circumferentially evenly spaced magnets are embedded in the lower end of the cover plate.

[0034] The above settings enable magnetic fixation between the top cover and the cover plate.

[0035] Preferably, the air outlet channel includes a first air outlet channel and a second air outlet channel, the first air outlet channel being connected to the receiving groove; and the lower end wall of the air guide shroud is provided with an air outlet that is connected to the second air outlet channel.

[0036] The above configuration enables a single fan to exhaust air from two parts. The first air outlet allows the smoke generated by the incense stick assembly to flow from the upper guide cavity and annular gap to the lower end of the guide hood. Then, the smoke at the lower end of the guide hood is discharged outward through the second air outlet.

[0037] Preferably, the second air outlet channel is provided with a rotating plate for controlling the airflow, and the rotating plate is controlled by a driver to control the rotation angle.

[0038] The above settings allow control over the airflow of the second air outlet, resulting in visually different views of the internal aromatherapy smoke flow. This also allows the second air outlet to have different airflow rates at the same fan speed, eliminating the need for voltage adjustments to control the fan's tiered airflow.

[0039] Compared with the prior art, the beneficial effects of this utility model are as follows: This solution optimizes the position of the incense cartridge component so that the upper end of the incense cartridge component is exposed when the cover is not closed, making it easy for the user to take it out. At the same time, the cover and the top cover are magnetically fixed, so it is very convenient to remove the cover. The airflow can be controlled by rotating the rotating plate, so that the fan can produce different smoke patterns at the same speed. Attached Figure Description

Furthermore, positioning hole 34 extends upward to directly below pressing portion 312, allowing lamp head 341 to illuminate pressing portion 312.

[0061] After the cover plate 3 covers the fragrance cartridge assembly 5, it can guide the aromatherapy smoke into the annular gap 71. A smoke leakage prevention structure is provided between the top cover 4 and the cover plate 3. This structure includes an annular groove 43 extending axially, with an L-shaped longitudinal section located on the inner wall of the top cover 4. An annular protrusion 36 for insertion into the annular groove 43 is provided at the lower end of the lower cover plate 33. An upwardly extending flange 511 is provided at the fragrance cartridge outlet 51 of the fragrance cartridge assembly 5, and the lower cover plate 33 has a fitting hole 38 that fits onto the flange 511. The upper cover plate 32 and the lower cover plate 33 are coaxially arranged, and a flow guide cavity 6 is provided at their center. The circumferential edge region of the flow guide cavity 6 communicates with the annular gap 71; the fitting hole 38 communicates with the flow guide cavity 6, ensuring that the smoke flows into the flow guide cavity 6, the annular gap 71, and the smoke viewing chamber 10. The circumferential edge regions of the upper cover plate 32 and the lower cover plate 33 are in contact with each other and fixed with adhesive to achieve a sealed fit. In some other embodiments, the smoke leakage prevention structure can also be sealed with sealing rings or adhesive to prevent leakage.

[0062] Among them, the lower cover plate 33 has four connecting ribs 37 at the periphery of the flow guide cavity 6 to connect the lower cover plate 33 itself, which has little impact on the flow of smoke.

[0063] like Figure 11 and Figure 12As shown, a fan 9 is also provided inside the air guide shroud 7. The air outlet of the fan 9 is connected to a first air outlet channel 81 and a second air outlet channel 82. The first air outlet channel 81 is connected to the receiving groove 73, and the fragrance cartridge assembly 5 has an axially extending through hole. The through hole is coaxially arranged with the receiving groove 73 and connected to the first air outlet channel 81, thereby realizing demisting. The end of the second air outlet channel 82 is connected to the lower wall of the air guide shroud 7. An air outlet block 75 is provided on the lower wall of the air guide shroud 7, and the air outlet block 75 has an air outlet. A rotating plate 83 for controlling the airflow is provided in the second air outlet channel 82. The rotation angle of the rotating plate 83 is controlled by a driver 84. The rotating plate 83 is a plate. When the rotating plate 83 is in a vertical state, it can block the entire second air outlet channel 82. When the rotating plate 83 is in a horizontal state, the airflow of the second air outlet channel 82 reaches its maximum. The driver 84 can be any existing motor that can control the rotation angle.

[0064] In some other embodiments, the top cover 4 can also be fixed to the visualization housing 2, and a fixed connection structure can be provided between the top cover 4 and the visualization housing 2, such as a similar structure to the above-mentioned card block 44 and card slot 721, to ensure that the defogging gap 21 still exists.

[0065] When the smoke aromatherapy device is in use, when aromatherapy atomization is needed, the rotating plate 83 remains vertical, thereby blocking the second air outlet channel 82 and allowing all the airflow to flow into the first air outlet channel 81. This causes the smoke to be sequentially carried along the airflow direction into the guide cavity 6, the annular gap 71, and the lower end of the guide hood 7 (smoke viewing cavity 10). When it is necessary to expel the smoke, the rotating plate 83 controls its rotation angle, causing the second air outlet channel 82 to open, allowing the smoke to be blown from bottom to top and discharged through the mist exhaust gap 21.

[0066] When it's time to replace the scent cartridge component 5, the user simply removes the cover plate 3, exposing the scent cartridge component 5, and then removes it directly. After placing the new scent cartridge component 5, simply replace the cover plate 3 on the top cover 4; it's very convenient.
