Description

Technical Field

[0001] The utility model relates to the technical field of aromatherapy, in particular to a heating aromatherapy cup. Background Art

[0002] At present, most of the household aromatherapy products used in the market, especially the car-mounted aromatherapy cups, use artificially synthesized fragrance bottles of various fragrances, which are generally in liquid or paste state, relying on natural volatilization or wind power to spread the fragrance. Many of these artificial fragrances extracted and synthesized contain complex chemical additives, some of which are easy to cause adverse reactions to the human body. This is also the main factor for many user groups to have allergies and other adverse reactions when using such artificial fragrances. Because everyone's physique is different, some people have special physiques. If they come into contact with artificial fragrances, they may have allergic reactions. Long-term smelling of artificial fragrances may cause redness, itching, and rashes on the skin, and may even increase the probability of respiratory diseases, such as tracheitis and bronchitis, so long-term excessive inhalation of fragrances should be avoided.

[0003] If natural spices, such as tea leaves, dried flowers, cinnamon, dried orange peel, etc., are used, it is impossible to achieve an efficient fragrance release effect by utilizing the natural volatilization of spices in most existing aromatherapy cup structures. Utility Model Content

[0004] The utility model provides a heating aromatherapy cup, which is conducive to solving the problem that the common aromatherapy cup structure on the market cannot be adapted to natural fragrances for efficient fragrance release.

[0005] The utility model is achieved in this way:

[0006] A heated aromatherapy cup comprises a cup body, wherein an open end is arranged on the top of the cup body, an inner bracket of an annular structure is arranged on the inner wall of the cup body, a circuit board is arranged on the inner bracket, a button extending to the outside of the cup body and an interface for connecting a power cord are connected to the circuit board, and the circuit board is also connected to a heating element located inside the cup body, wherein the heating element is an annular structure, a built-in cup is attached to the inner side of the heating element, a cavity for accommodating natural fragrances is arranged inside the built-in cup, and the heating element can perform intermittent heating on the natural fragrances in the cavity, and the built-in cup has an opening structure on one side close to the open end of the cup body, a detachable cover body is arranged at the opening structure, and an air vent is arranged on the cover body, and the air vent enables the cavity inside the built-in cup to communicate with the space outside the cup body.

[0007] On the basis of the above technical solution, the cup body comprises a main body, the open end is located at the top of the main body, and a base is provided at the bottom of the main body.

[0008] Based on the above technical solution, the outer side wall of the main body is provided with a concave-convex texture.

[0009] Based on the above technical solution, a wrapping piece is arranged on the outer side wall of the main body near the open end area.

[0010] Based on the above technical solution, the inner bracket is close to the outer wall of the cup body, a sink is provided on the top of the inner bracket, and a flange matching the sink is provided on the top of the built-in cup. When the built-in cup is installed, the flange and the sink abut against each other to form a longitudinal limiting structure.

[0011] Based on the above technical solution, a U-shaped mounting frame is provided at the bottom of the built-in cup, and a card slot is provided on the mounting frame; a card column adapted to the card slot is provided on the base, and the card column and the card slot can form a longitudinal limiting card structure through relative rotation.

[0012] On the basis of the above technical solution, the clamping column is located at the top of the base, and a bottom plate is fixedly provided at the bottom of the outer end of the base.

[0013] On the basis of the above technical solution, an elastic member is provided on the inner wall of the clamping slot, and the elastic member can form an anti-loosening structure for the clamping column after clamping by utilizing elastic deformation.

[0015] On the basis of the above technical solution, the elastic member is a "D"-shaped structure, and its arc structure is the deformation part.

[0016] Compared with the prior art, the utility model has at least the following advantages:

[0017] 1. The utility model can safely and stably accelerate the volatilization of the fragrance by arranging a heating element in the cup body, which heats the natural fragrance in the built-in cup at intervals. This heating method allows the fragrance molecules to diffuse into the air more quickly, improving the fragrance release efficiency. This structure can also solve the problem that the existing common aromatherapy cups can only release fragrance passively and cannot adapt to natural fragrances for efficient fragrance release.

[0018] 2. The utility model uses the design of the built-in cup to effectively isolate the spices in the cavity, avoiding direct contact between the spices and the heating element, thereby reducing the possibility of the spices being burned or damaged. At the same time, a detachable cover is provided at the opening of the built-in cup, which can further protect the spices from external contamination and prevent the internal spices from leaking out during use.

[0019] 3. The utility model uses natural fragrances as the source of aromatherapy, which is more environmentally friendly and healthy than chemically synthesized aromatherapy products. At the same time, since the design of the heated aroma cup can efficiently release the aroma of natural fragrances, users can reduce the intake of chemical substances while enjoying the aroma.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to an element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0036] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Example 1: See Figures 1 to 7 This embodiment discloses a heating aroma cup, comprising a cup body 1, a cover body 2, an inner bracket 3, a circuit board 4, a heating element 5, a built-in cup 6, a mounting frame 7, a wrapping element 8 and a bottom film 9. The built-in cup 6 is used to contain natural fragrances, and the heating element 5 can perform interval heating on the fragrances inside the built-in cup 6, so that when the fragrances are heated to a suitable temperature, the volatilization of the fragrance molecules is accelerated, thereby realizing active heating aromatherapy of the natural fragrances.

[0038] The cup body 1 includes a main body 11 of a cylindrical structure, and an open end 13 is provided on the top of the main body 11, so that its internal space can be connected to the external space, providing basic conditions for the subsequent installation and disassembly of components in its internal space. A base 12 is provided at the bottom of the main body 11. In this embodiment, the open end 13, the main body 11 and the base 12 are fixedly connected structures. Specifically, the main body 11 and the open end 13 are an integrated structure, and the base 12 is fixedly connected to the bottom end of the main body 11 (in this embodiment, the main body 11 is made of aluminum alloy, and the base 12 is made of hard plastic. The base 12 is fixedly connected to the bottom end of the main body 11 by hot-melt bonding. In other implementations, the connection method between the two is different according to different materials. The connection method can be used according to actual conditions but is not limited to gluing, welding, threaded connection, fastener locking, and snap-on connection).

[0039] Furthermore, the outer wall of the main body 11 is provided with a concave-convex texture, specifically a knocking pattern, which uses the concave-convex structure to increase the friction during gripping, thereby improving the convenience and safety of gripping. In addition, it can also increase the appearance of the product.

[0040] A wrapping piece 8 is disposed on the outer wall of the main body 11 near the open end 13. Figure 1 and Figure 2 The wrapping piece 8 is specifically a "C"-shaped ring piece made of hard plastic, which is fixed to the outer wall of the main body 11 by gluing. Its function is to enrich the outer structure of the main body 11 and further improve the comfort and safety of gripping. In addition, it also provides a carrier for display. Its color can be designed to enhance the beauty of the product. Patterns and texts can also be designed on its surface to achieve the effect of information display.

[0041] An inner bracket 3 of an annular structure is arranged on the inner side wall of the cup body 1, and a circuit board 4 is arranged on the inner bracket 3. The function of the current board is to control the heating system. The circuit board 4 is connected to a button 41 extending to the outside of the cup body 1 and an interface 42 for connecting a power cord. Another function of the above-mentioned wrapping member 8 is to cover the assembly gap between the button 41 and the cup body 1, forming a dust-proof and anti-falling protection structure for the button 41.

[0042] Specifically, refer to Figure 3As shown, the inner bracket 3 is tightly attached to the outer wall of the cup body 1, a sink 31 is provided on the top of the inner bracket 3, and a flange 61 matched with the sink 31 is provided on the top of the built-in cup 6. When the built-in cup 6 is installed, the flange 61 and the sink 31 abut against each other to form a longitudinal limiting structure. It should be noted that, in this embodiment, the base 12 and the main body 11 are fixedly connected, and the built-in cup 6 is an independent and detachable structure. The longitudinal limiting structure formed by the flange 61 and the sink 31 abutting against each other can provide assistance when installing the built-in cup 6, and the fixing of the built-in cup 6 is achieved by the snap connection between the mounting frame 7 at its bottom and the base 12.

[0043] Furthermore, the circuit board 4 is also connected to a heating element 5 located on the inner side of the cup body 1. The heating element 5 is an annular structure, and a built-in cup 6 is attached to the inner side of the heating element 5 (after the built-in cup 6 is installed, the outer wall of the built-in cup 6 is in a fitting relationship with the inner wall of the heating element 5, and heat conduction can be performed between the two). A cavity for accommodating natural spices is provided inside the built-in cup 6, and the heating element 5 can perform intermittent heating on the natural spices in the cavity. In this embodiment, the heating element 5 specifically adopts a heating plate, which is a prior art. Its specific structure and working principle will not be described here. Those skilled in the art can select and implement it from the prior art according to the actual working conditions. It should be noted that the outside of the heating plate is wrapped with high temperature resistant rubber. The function of the high temperature resistant rubber is to prevent the heating plate from directly contacting the built-in cup 6 and to evenly disperse and conduct the heat generated by the heating plate.

[0044] The side of the built-in cup 6 close to the open end 13 of the cup body 1 is an open structure, and a detachable cover body 2 is provided at the opening structure. Figure 4 The outer contour of the cover body 2 is a structure that is wide at the top and narrow at the bottom. It can be pressed and inserted into the opening at the top of the built-in cup 6, which plays a relatively sealing role on the inner cavity and prevents the internal fragrance from leaking out from the opening. The cover body 2 is provided with an air hole 21. The air hole 21 makes the cavity inside the built-in cup 6 communicate with the outer space of the cup body 1. It should be noted that in this embodiment, the cover body 2 is divided into a closed area and an open area. There are several air holes 21 with fan-shaped through-hole structures evenly distributed in the area of ​​the open area. During use, the aromatic molecules volatilized by the fragrance in the inner cavity can be evenly diffused to the external space through the air holes 21. This partition structure can effectively control the airflow interaction efficiency between the inner cavity and the external space, control the fragrance release direction in an orderly manner, and also control the temperature maintenance in the inner cavity in an orderly manner.

[0045] For further reference, Figure 6The bottom of the built-in cup 6 is provided with a U-shaped mounting frame 7, and the mounting frame 7 has upwardly bent side panels 71 on both sides. The side panels 71 are welded and fixed to the two sides of the bottom of the built-in cup 6. The mounting frame 7 can move synchronously with the built-in cup 6. The mounting frame 7 is provided with two centrally symmetrically arranged card slots 72, and the card slots 72 form an opening structure at the edges of both sides of the mounting frame 7; the base 12 is provided with a card column 14 adapted to the card slot 72, and the longitudinal section profile of the card column 14 is a "T"-shaped structure. The card column 14 and the card slot 72 can form a longitudinal limit card connection structure through relative rotation. Figures 5 to 7 As shown, when clamped, the mounting frame 7 follows the insertion movement of the built-in cup 6 and approaches the clamping column 14. From a top-down perspective, the built-in cup 6 is rotated counterclockwise to drive the mounting frame 7 to rotate, and the horizontal plane of the clamping groove 72 changes position, which also causes relative movement of the clamping column 14. The clamping column 14 will enter the clamping groove 72 to form a longitudinal limit clamping structure, so that the built-in cup 6 is constrained and controlled and cannot move out from the inside of the cup body 1. The constraint can be released by reverse rotation.

[0046] Furthermore, the clamping column 14 is located at the top of the base 12, and a bottom film 9 is fixedly provided at the bottom of the outer end of the base 12. The bottom film 9 is an elastic gasket, so that the bottom of the cup body 1 can improve the anti-slip effect when it is placed. In other embodiments, an adhesive layer can also be provided at the bottom of the bottom film 9, so that it can fix the cup body 1 in a specific position.

[0047] In the specific implementation process, the cover body 2 is opened and closed to add or pour natural fragrance into the built-in cup 6. When performing aromatherapy, the heating element 5 performs intermittent heating on the internal fragrance, so that the natural fragrance evaporates faster after being heated. The volatilized aromatic molecules diffuse to the external space through the air holes 21, achieving the effect of efficient fragrance release.

[0048] Embodiment 2: Based on Embodiment 1, the main difference of this embodiment is that the base 12 and the main body 11 are non-fixed connection structures, while the built-in cup 6 is fixedly connected to the cup body 1 through the turning edge 61 and the sink 31, so that the built-in cup 6 and the cup body 1 are fixedly connected. In this embodiment, the card slot 72 and the card column 14 on the mounting frame 7 can also be used for convenient disassembly and assembly. The difference is that after disassembly and assembly, the cup body 1 and the built-in cup 6 are synchronous movable parts, and are synchronously separated from the base 12. The advantage of this structure is that the connection between the built-in cup 6 and the heating element 5 is relatively stable and reliable, which can greatly reduce the failure rate of the connection relationship between the internal components.

[0049] Embodiment 3: Based on Embodiment 1, Figure 8As shown, in order to further improve the stability of the structural connection, an elastic member 73 made of elastic plastic is provided on the inner wall of the slot 72. The elastic member 73 can form an anti-loosening structure for the clamping column 14 by elastic deformation. Specifically, the elastic member 73 is a "D"-shaped structure, and its arc structure is a deformation part. When the clamping column 14 enters the slot 72, the deformation part of the elastic member 73 is squeezed. After squeezing, the clamping column 14 continues to move inward. Then, the deformation part of the elastic member 73 is reset to form a barrier structure to prevent the clamping column 14 from moving outward relative to the slot 72. The clamping column 14 can be rotated out of the slot 72 by manual force operation to release the clamping constraint between the slot 72 and the clamping column 14.

[0050] Embodiment 4: This embodiment discloses the circuit diagram details of the circuit board in Embodiment 1.

[0051] refer to Fig. 9 , which is the power supply part. By adding the VDR1 varistor, the voltage is clamped to a relatively fixed voltage value, thereby realizing the protection of the subsequent circuit. F1 is a PTC self-recovery fuse, which can resume the system after the overcurrent is released. U2 and U3 output 12V and 5V voltages respectively, which provide power for the MOS tube of the subsequent power and the microcontroller of the control unit.

[0052] refer to Fig.10 , which is the PWM drive and power output part. The PWM drive adopts totem pole drive, and the diode D1 is connected in parallel to the input MOS tube M1 resistor R3, which can speed up the discharge speed and effectively and quickly turn off or turn on the MOS tube to avoid the poor damping effect of the MOS tube switch and generate a lot of heat.

[0053] refer to Fig.11 , which includes input voltage judgment and temperature sampling circuits. The system can judge whether the system is connected to a 12V or 24V system based on different VCHK voltages, thereby outputting different PWM signals to drive the power output circuit to achieve consistent power output under different voltage systems of 12V or 24V; Fig.11 The middle left part is the temperature sampling circuit. Capacitor C6 is close to the MCU for effective filtering and absorbs some spike glitch signals.

[0054] This temperature constant temperature system is a closed-loop control system that stably collects the current temperature and uses temperature parameters as the controlled variable. Specifically, it uses the PID control method to set the appropriate integral coefficient, differential coefficient and proportional coefficient, and negative feedback controls the set temperature. The PWM working time that needs to be adjusted is calculated through the last temperature deviation and the accumulated value of historical errors, and then the heating output is controlled to achieve the constant temperature state set by the system.

[0055] Among them, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it; although the utility model is described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some of the technical features therein with equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the utility model.
