[0047] The present application provides an essential oil bottle.

[0048] Please refer to Figures 1 to 4 In an embodiment of the present application, the essential oil bottle comprises a bottle body 10, a liquid level sensor 20 and a sensing float 30. The liquid level sensor 20 is detachably connected to the bottle body 10. The sensing float 30 is placed in the bottle body 10 and is signal connected with the liquid level sensor 20. The sensing float 30 is used to rise and fall accordingly with the change of the liquid level of the bottle body 10, so that the liquid level sensor 20 detects the position change of the sensing float 30.

[0049] The bottle body 10 is the main part of the essential oil bottle and is used to contain essential oil. Its shape can be designed as a cylinder, an ellipse or other irregular shapes according to actual needs to meet the use habits and aesthetic needs of different users. The material of the bottle body 10 can be selected from glass, plastic or metal, etc. The glass material has good transparency, which is convenient for users to intuitively observe the liquid level of the essential oil. The plastic material has the characteristics of lightness and anti-falling. The metal material has more texture and durability.

[0050] In some special application scenarios, such as the need to prevent the influence of light on essential oils, the bottle body 10 can be made of opaque materials, such as frosted glass, dark plastic or metal, etc. In addition, the capacity of the bottle body 10 can be adjusted according to the usage of essential oils to meet the needs of different user groups.

[0051] The liquid level sensor 20 is a key component for detecting the liquid level of essential oils, which can be detachably connected to the bottle body 10. This detachable design facilitates users to clean, replace or maintain the liquid level sensor 20, prolonging its service life. The liquid level sensor 20 usually contains sensor elements inside, such as capacitive, inductive or optical sensors, etc. When the position of the sensing float 30 changes, the liquid level sensor 20 can detect the change of the signal through the sensor elements, thereby accurately determining the liquid level height of essential oils.

[0052] For different essential oil components and use environments, the type of liquid level sensor 20 can be selected. For example, in the case of containing conductive essential oils, a capacitive liquid level sensor 20 can be used; in the case of high precision requirements, an optical liquid level sensor 20 can be used. In addition, the liquid level sensor 20 can also be connected with external display devices (such as mobile phone APP, display screen, etc.), and through wireless communication modules (such as Bluetooth, Wi-Fi, etc.), the liquid level information can be transmitted to the user in real time, so that the user can check the use of essential oils at any time.

[0053] The sensing float 30 is placed in the bottle body 10, and its material is usually light and has buoyancy, such as plastic, foam, etc. The shape of the sensing float 30 can be designed as a circle, a square or other irregular shapes to adapt to the internal space of the bottle body 10. The sensing float 30 is connected with the liquid level sensor 20 through a signal, and when the liquid level of essential oils changes, the sensing float 30 will move accordingly with the rise and fall of the liquid level, thereby triggering the liquid level sensor 20 to detect the signal of position change.

[0054] The material of the sensing float 30 can be adjusted according to the density and viscosity of essential oils. For example, for essential oils with high density, a float material with low density can be used to ensure that the float can normally float on the liquid surface. In addition, the sensing float 30 can also be designed with magnetic or conductive materials to facilitate more effective signal transmission with the liquid level sensor 20. For example, using a magnetic float with a magnetic induction type liquid level sensor 20 can improve the sensitivity and accuracy of detection.

[0055] When the essential oil bottle is in normal use, the liquid level of the essential oil will gradually decrease as the essential oil is used. At this time, the inductive float 30 will move downward accordingly as the liquid level decreases. The change in the position of the inductive float 30 will be transmitted to the liquid level sensor 20 through the signal connection. After the sensor element inside the liquid level sensor 20 receives the signal, it will analyze and process it, and feed back the liquid level information to the user or the external device connected thereto.

[0056] When the user uses the machine, as the essential oil is atomized and blown out, the essential oil in the bottle decreases, and the inductive float 30 also decreases. After the liquid level sensor 20 detects the change in the position of the inductive float 30, it will display the current liquid level of the essential oil in real time through the built-in display module (such as a liquid crystal display screen). If the liquid level sensor 20 is connected to an external device (such as a mobile phone APP), it will also send the liquid level information to the user's mobile phone through the wireless communication module, reminding the user of the remaining amount of essential oil and facilitating the user to replenish the essential oil in time.

[0057] The essential oil bottle can be easily detached from the pump body host through the detachable design of the liquid level sensor 20 and the cooperative work of the inductive float 30 and the liquid level sensor 20. This design not only facilitates the user to quickly replace the essential oil bottle, but also effectively reduces the maintenance difficulty and cost of the fragrance diffuser. Specifically, the detachable liquid level sensor 20 enables the user to replace the essential oil bottle without complex disassembly operation of the fragrance diffuser, thereby reducing the risk of equipment damage caused by frequent disassembly and assembly. At the same time, the precise liquid level monitoring function of the inductive float 30 can avoid the idle running of the fragrance diffuser due to insufficient essential oil, further prolonging the service life of the equipment. This design not only improves the user experience of the fragrance diffuser, but also enhances the competitiveness of the fragrance diffuser in the market by reducing the maintenance cost and improving the reliability of the equipment.

[0058] In an embodiment, please refer to Figures 1 to 4 , the essential oil bottle further comprises a liquid level sensing bracket 40, the liquid level sensing bracket 40 comprises a bracket body 41 and a bracket cover 42, the bracket body 41 is fixed to the bottle body 10; a plurality of first magnetic attraction blocks are arranged on the side of the bracket body 41 away from the bottle body 10, and the plurality of first magnetic attraction blocks are arranged at intervals; the bracket body 41 is also provided with an inner cavity 31a, and the plurality of first magnetic attraction blocks are arranged at intervals with the inner cavity 31a, and the liquid level sensor 20 is installed in the inner cavity 31a; the bracket cover 42 is provided with a plurality of second magnetic attraction blocks 42a, and the plurality of second magnetic attraction blocks 42a are arranged at intervals; each second magnetic attraction block 42a is connected with a first magnetic attraction block by adsorption, so that the bracket cover 42 and the bracket body 41 are detachably connected.

[0059] The bracket body 41 is the basic component of the liquid level sensing bracket 40, which is fixed on the bottle body 10 and serves to support and install the liquid level sensor 20. The shape of the bracket body 41 can be designed according to the structure of the bottle body 10, and is usually cylindrical, square or other shapes that fit the bottle body 10 to ensure close fit and stable fixation with the bottle body 10. The material of the bracket body 41 can be plastic, metal or composite material, among which plastic material has the characteristics of light weight and low cost, and metal material has high strength and durability.

[0060] In some application scenarios, the bracket body 41 can be designed to be adjustable, such as being connected to the bottle body 10 through threads or buckles, to adapt to bottle bodies 10 of different diameters or shapes. In addition, the surface of the bracket body 41 can be treated to prevent slipping, such as adding rubber pads or anti-slip textures, to improve its fixation effect with the bottle body 10.

[0061] The bracket cover 42 is used to cover the bracket body 41, serving to protect the liquid level sensor 20 and aesthetics, and is also a battery cover with internal protection. The shape of the bracket cover 42 is adapted to the bracket body 41, and is usually designed as cylindrical, square, etc. to ensure that it can closely fit the bracket body 41. The material of the bracket cover 42 can also be plastic, metal or composite material, and the specific selection can be adjusted according to the appearance design and cost requirements of the product. In addition, the surface of the bracket cover 42 can be treated specially, such as painting or electroplating, to improve the appearance quality of the product.

[0062] The first magnetic block is arranged on the side of the bracket body 41 away from the bottle body 10, used to cooperate with the second magnetic block 42a on the bracket cover 42 to realize the detachable connection of the bracket cover 42 and the bracket body 41. Multiple first magnetic blocks are arranged at intervals, which can ensure the stability and uniformity of the connection. The material of the first magnetic block is usually a permanent magnet, such as a neodymium iron boron magnet, which has strong magnetism and can ensure the firm connection of the bracket cover 42 and the bracket body 41.

[0063] The shape of the first magnetic block can be designed as circular, square or other shapes to adapt to the structure of the bracket body 41. In addition, the number and interval of the first magnetic block can be adjusted according to actual needs, such as arranging more magnetic blocks on a larger bracket body 41 to enhance the connection strength.

[0064] The second magnetic block 42a is arranged on the bracket cover 42 and corresponds to and is attracted to the first magnetic block. Multiple second magnetic blocks 42a are also arranged at intervals and form stable magnetic attraction with the first magnetic blocks. The material of the second magnetic block 42a is also a permanent magnet, and its magnetism matches that of the first magnetic block to ensure firm attraction.

[0065] The shape and number of the second magnetic attraction blocks 42a can be adjusted according to the structure of the bracket outer cover 42 to ensure optimal cooperation with the first magnetic attraction blocks. In addition, the second magnetic attraction blocks 42a can be designed as a detachable structure, such as being fixed on the bracket outer cover 42 by screws or buckles, so as to be replaced when needed.

[0066] The shape and size of the inner cavity 31a are designed according to the structure of the liquid level sensor 20 to ensure that the liquid level sensor 20 can be stably installed in the inner cavity 31a. The design of the inner cavity 31a can also include some fixing structures, such as a clamping groove or a thread, for further fixing the liquid level sensor 20.

[0067] In actual use, the liquid level sensor 20 is installed in the inner cavity 31a of the bracket body 41, and the bracket outer cover 42 is connected to the bracket body 41 by the second magnetic attraction blocks 42a and the first magnetic attraction blocks on the bracket body 41, thereby fixing the bracket outer cover 42 on the bracket body 41. When it is necessary to disassemble the bracket outer cover 42, the user only needs to exert a certain force to overcome the magnetic attraction force, and then the bracket outer cover 42 can be disassembled from the bracket body 41. This detachable design makes it convenient for the user to maintain, replace, or clean the liquid level sensor 20, and also facilitates the cleaning and inspection of the inside of the bracket.

[0068] The liquid level sensing bracket 40 in this embodiment realizes the detachable connection of the bracket outer cover 42 and the bracket body 41 through the magnetic attraction connection of the first magnetic attraction blocks and the second magnetic attraction blocks 42a. This design not only facilitates the user to quickly disassemble and install the bracket outer cover 42, thereby facilitating the maintenance and replacement of the liquid level sensor 20, but also improves the overall maintainability and service life of the product. At the same time, the inner cavity 31a of the bracket body 41 provides a stable installation environment for the liquid level sensor 20, ensuring its normal operation. In addition, by selecting different materials and structural designs, this liquid level sensing bracket 40 can adapt to different application scenarios and use requirements, and has high universality and flexibility.

[0069] In an embodiment, referring to Figures 1 to 4 , the bracket outer cover 42 includes an outer cover body 421 and a liquid level sensing cover 422, the outer cover body 421 is provided with at least one opening 421a and a plug-in sliding strip 421b extending along both sides of the opening 421a; the liquid level sensing cover 422 is provided with a sliding groove 422a corresponding to each plug-in sliding strip 421b, and each plug-in sliding strip 421b slides into a sliding groove 422a, so that the liquid level sensing cover 422 is plugged into the outer cover body 421 and covers the opening 421a.

[0070] The outer cover body 421 is the base part of the bracket outer cover 42, and its main function is to provide a mounting base for the liquid level sensing cover 422 and to achieve the fixation and protection of the liquid level sensing cover 422 through its structural design. The outer cover body 421 is provided with at least one opening 421a for accommodating the liquid level sensor 20 or other related components for operation or observation when needed. The plug-in sliding strips 421b arranged on both sides of the opening 421a are the key structural features of the outer cover body 421, which are used to cooperate with the sliding grooves 422a on the liquid level sensing cover 422 to achieve the plug-in fixation of the liquid level sensing cover 422. In addition, the number and layout of the plug-in sliding strips 421b can also be optimized according to the size and shape of the opening 421a, such as increasing or reducing the number of sliding strips, or changing their arrangement, to improve the stability and reliability of the plug-in.

[0071] The liquid level sensing cover 422 is an important component of the bracket outer cover 42, and its main function is to cover the opening 421a of the outer cover body 421 and protect the liquid level sensor 20 from external interference and damage. The liquid level sensing cover 422 is provided with a sliding groove 422a corresponding to each plug-in sliding strip 421b, and these sliding grooves 422a cooperate with the plug-in sliding strips 421b to enable the liquid level sensing cover 422 to be plugged onto the outer cover body 421 and cover the opening 421a. The material of the liquid level sensing cover 422 is usually transparent or translucent, so that the user can directly observe the working state of the liquid level sensor 20.

[0072] In actual use, the liquid level sensing cover 422 is plugged and fixed through the cooperation of the sliding grooves 422a on it and the plug-in sliding strips 421b on the outer cover body 421. Align the liquid level sensing cover 422 with the opening 421a of the outer cover body 421, so that the sliding grooves 422a on the liquid level sensing cover 422 are aligned with the plug-in sliding strips 421b on the outer cover body 421. Apply a certain force to slide the liquid level sensing cover 422 along the direction of the plug-in sliding strips 421b, so that the plug-in sliding strips 421b are completely inserted into the sliding grooves 422a. When the liquid level sensing cover 422 is slid into place, it will completely cover the opening 421a of the outer cover body 421, thereby achieving the covering and protection of the opening 421a. When it is necessary to disassemble the liquid level sensing cover 422, it is only necessary to reverse the operation and slide the liquid level sensing cover 422 out along the direction of the plug-in sliding strips 421b. This plug-in design makes the installation and disassembly process of the liquid level sensing cover 422 simple and fast, and facilitates the user to maintain, replace or check the liquid level sensor 20.

[0073] The structure of the support outer cover 42 in this embodiment realizes the quick insertion and disassembly of the liquid level sensing cover 422 through the cooperation of the insertion sliding strip 421b on the outer cover body 421 and the sliding groove 422a on the liquid level sensing cover 422. This design not only simplifies the installation and disassembly process of the liquid level sensing cover 422, improves the user's convenience, but also effectively protects the liquid level sensor 20 from external interference and damage through the shielding opening 421a, improving the reliability and service life of the product.

[0074] In an embodiment, referring to Figures 1 to 4 , the liquid level sensor 20 includes an induction PCB board 21, a Bluetooth module, and a battery 22. The induction PCB board 21 is installed on the outer cover body 421 and is arranged opposite to the induction float 30. The induction PCB board 21 is used to detect the position change of the induction float 30 and record the liquid level information. The Bluetooth module is built-in on the induction PCB board 21 and is electrically connected with the induction PCB board 21. The Bluetooth module is used to wirelessly transmit the liquid level data of the induction PCB board 21. The battery 22 is fixed on the outer cover body 421 and is electrically connected with the induction PCB board 21 and the Bluetooth module. The battery 22 is used to provide power supply for the induction PCB board 21 and the Bluetooth module. The battery 22 is arranged opposite to the opening 421a.

[0075] The induction PCB board 21 is the core component of the liquid level sensor 20, which is installed on the outer cover body 421 and arranged opposite to the induction float 30. Its main function is to detect the position change of the induction float 30 and convert these changes into liquid level information for recording. The induction PCB board 21 integrates various electronic components such as sensors, processors, etc. for realizing liquid level detection and data processing functions. The shape of the induction PCB board 21 is usually rectangular, and the size is designed according to the internal space of the outer cover body 421 to ensure its stable installation.

[0076] The shape and size of the induction PCB board 21 can be adjusted according to actual needs, such as designed as a circle or other irregular shapes to adapt to different installation spaces. In addition, the material of the induction PCB board 21 can be selected as high-performance insulating materials such as polyimide (PI) or glass fiber reinforced epoxy resin to improve its durability and reliability.

[0077] The Bluetooth module is built into the sensing PCB board 21 and is electrically connected with the sensing PCB board 21. Its main function is to transmit the liquid level data detected by the sensing PCB board 21 to external devices (such as smartphones, tablets, etc.) through wireless communication, making it convenient for users to view the liquid level information in real time. The Bluetooth module usually adopts low-power Bluetooth technology (BLE) to reduce the consumption of battery 22 power. In addition to the Bluetooth module, other wireless communication modules such as Wi-Fi modules or NFC modules can also be used to meet different communication needs. For example, in scenarios that need to be integrated with smart home systems, Wi-Fi modules may be more suitable; while in close-range transmission scenarios, NFC modules can provide faster connections.

[0078] The battery 22 is fixed to the outer cover body 421 and is electrically connected with the sensing PCB board 21 and the Bluetooth module, providing power for the entire liquid level sensor 20. The installation position of the battery 22 is opposite to the opening 421a, so as to facilitate users to replace the battery 22.

[0082] The induction PCB board 21 is the core component of the liquid level sensing system, which is used for detecting the position change of the induction float 30 and recording the liquid level information. The induction PCB board 21 is provided with a plurality of Hall elements 21a, which are arranged at intervals along the height direction of the bottle body 10.
