Description

Technical Field

[0001] This invention belongs to the field of medical instruments, and in particular relates to a rapid olfactory material switching device for use in home olfactory devices. Background Technology

[0002] Odors are initially detected by odor receptors (ORs) expressed in the cilia of olfactory sensory neurons (OSNs) within the olfactory epithelium (OE). The olfactory epithelium (OE) is a specialized neuroepithelium located primarily above the superior turbinate, at the deepest part of the nose. Damage to the OE caused by viral and bacterial infections, toxic exposure, and other factors is a major basis for changes in human olfactory function. This study explores the basic organization of the olfactory epithelium (OE), the molecular mechanisms involved in initial odor transduction, and factors influencing the regenerative response of OSNs to neuronal damage. [1] The earliest symptoms of AD include impaired olfactory recognition and odor recognition memory. [2，3] Therefore, olfactory dysfunction is an important and early-stage factor related to AD pathology. [4，5] Improving olfactory function is an important goal in alleviating cognitive neuropathological changes in AD patients.

[0003] While there are existing devices that improve the sense of smell, such as "a ceiling fan with an easily replaceable aromatherapy diffuser,"... [6] The device includes: a boom, the end of which is fixedly connected to a first housing, and a second housing detachably connected to the first housing; a motor, located within the first housing, with its output shaft rotatably connected to a turntable; fan blades, located on the turntable; and an aromatherapy oil holder, detachably installed within the second housing, which contains an aromatherapy heater for heating the essential oils on the holder. The second housing can move upwards along the boom to expose the aromatherapy oil holder. By detachably connecting the first and second housings, the aromatherapy oil holder is detachably located within the first housing. When changing the aromatherapy oil, the second housing is moved to expose the holder, allowing for replacement. After replacement, the second housing is returned to its original position. This is exemplified by "an aromatherapy machine that facilitates the replacement of essential oil containers." [7] The diffuser includes an air outlet connector, an atomizing assembly, a lower atomizing assembly, a connector, an air inlet pipe, an essential oil container, a connector return seat, and a return spring, all housed within the diffuser housing. The air outlet connector is embedded in the atomizing assembly. An air inlet on the atomizing assembly passes through the lower part of the atomizing assembly and connects to the connector. One end of the air inlet pipe connects to the connector, and the other end extends into the essential oil container. A connector return seat and a return spring for driving the connector return seat are located at the bottom of the essential oil container. During use, the connector, connector return seat, and return spring hold the essential oil container in place. The diffuser also includes a rotating door mechanism for easy replacement of the essential oil container; similar to "a ceramic aromatherapy lamp for easy replacement of aromatherapy items." [8]The device includes an upper cylinder with a cover plate on its upper surface. The cover plate has several evenly spaced ventilation holes on its upper surface. A connecting rod is fixedly connected to the lower surface of the upper cylinder, and a fixing block is fixedly connected to the end of the connecting rod away from the upper cylinder. A lower cylinder is located on the lower surface of the upper cylinder, with a connecting groove on its upper surface and a fixing groove inside the connecting groove on the lower cylinder. By using the connecting rod and connecting groove, when replacing the aromatherapy block, the upper cylinder can be rotated around the connecting rod as an axis. The aromatherapy block is then inserted into the fixing post. After replacement, the first and second magnetic adsorption rings can quickly position the upper and lower cylinders, thus achieving rapid replacement of the aromatherapy block and greatly improving practicality. However, none of the above existing technical solutions can achieve the performance and functions required for a home olfactory device.

[0004] In the field of medical devices, existing technologies mainly rely on the complete disassembly and replacement of the odorant material to change the fragrance bottle (odorant bottle). This approach has the following drawbacks: 1. Existing technologies are too complex for the elderly; without the presence of their children or someone familiar with the device, it is difficult for them to change the fragrance bottle independently; 2. Existing technologies have a slow switching speed; 3. Existing technologies involve numerous switching steps.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] It should be noted that if directional terms or sequential terms such as "up", "down", "front", "back", "left", "right" are mentioned in the following embodiments, they are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the present invention.

[0037] The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of this specification. The singular forms “a,” “the,” and “the” used in one or more embodiments of this specification and in the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0038] This invention provides a quick-change device for olfactory materials in an olfactory device, comprising a fragrance bottle, a conduit, a spring, a small drawer (supporting device), and a cantilevered buckle. After pressing the cantilevered buckle, the spring pops out, and the drawer pops out as well. The user can then remove the fragrance bottle from the drawer with their fingers to change the fragrance bottle. This device is convenient and easily adaptable for elderly users to change fragrance bottles, and is readily applicable. The structure of this invention is described in detail below.

[0039] The present invention provides a rapid olfactory material switching device for use in home olfactory devices, which mainly consists of the following parts:

[0040] Fragrance bottle 2, as described above, is used to store fragrances.

[0041] Gas conduit 1, one end of which is connected to fragrance bottle 2, and the other end of which is connected to a component (such as a solenoid valve) in the olfactory instrument that regulates the flow of gas. Gas conduit 1 is used to guide the flow of gas to deliver gas to the olfactory instrument.

[0042] Supporting device 3 is used to support and fix the fragrance bottle 2, so that the fragrance bottle 2 remains stable.

[0043] The baffle 4 is directly connected to the external metal structure of the olfactory instrument, located on the outside of the support device 3 and on the same side as the spring 5. The baffle 4 can limit the pressing position of the support device 3 and prevent the support device 3 from being pressed in excessively and damaging the internal instruments of the olfactory instrument.

[0044] Spring 5 is used to connect the support device 3 and the internal device of the olfactory instrument, so that the support device 3 can move horizontally quickly within the elastic deformation range of the spring 5, so as to quickly replace the olfactory material.

[0045] The cantilever buckle 6 is fixed to the lower part of the support device 3. When in use, the cantilever buckle 6 only needs to be pushed outward, and the support device 3 will be pushed out by the elastic force of the spring 5. When it is necessary to fix the support device 3, the support device 3 only needs to be pushed inward to a suitable position, and the cantilever buckle 6 will be locked and fixed to the edge of the olfactory device, and the support device 3 connected to the cantilever buckle 6 will also be fixed in a suitable position.

[0046] In some embodiments of the present invention, please refer to Figures 1-3 The cross-sectional shape of the supporting device 3 is U-shaped.

[0047] In some embodiments of the present invention, please refer to Figures 1-3 The upper surface of the supporting device 3 is recessed with a supporting groove, the inner diameter of which is larger than the outer diameter of the fragrance bottle 2, so that the fragrance bottle 2 can be placed in the supporting groove.

[0048] In some embodiments of the present invention, the two ends of the spring 5 are respectively fixed to the bracket inside the olfactory instrument and the center of the support device 3.

[0049] In some embodiments of the present invention, there are two baffles 4, which are located on the same plane and are symmetrically arranged with respect to the center of the spring 5.

[0050] In some embodiments of the present invention, the cantilever buckle 6 is located on the opposite side of the support device 3 opposite to the spring 5.

[0051] The technical solution of this invention adopts the design of the cantilever buckle 6 and the baffle 4, which can select and quickly switch different fragrance bottles according to needs. The design structure is simple, occupies little space, and is suitable for small devices such as olfactory instruments.

[0052] Compared with replacing the entire olfactory material device, the olfactory material quick switching device using the cantilever buckle 6-spring 5-support device 3 provided in the foregoing embodiments of the present invention can reduce the switching steps, speed up the switching speed, and is easy for the elderly to operate.

[0053] In the olfactory material quick-change device for an olfactory instrument, consisting of the fragrance bottle 2, the gas conduit 1, the spring 5, the support device 3, and the cantilever buckle 6, the two ends of the spring 5 are fixed between the bracket inside the olfactory instrument and the support device 3. Both baffles 4 are directly connected to the external metal structure of the olfactory instrument, and the two baffles 4 and the spring 5 are located on the same side. Pressing the cantilever buckle 6 causes the spring 5 to pop out, and the support device 3 also pops out. The user can then use their fingers to pull open the support device 3 containing the fragrance bottle to replace the fragrance bottle 2. This device makes it easy for the elderly to change the fragrance bottle, and is convenient and widely applicable.

[0054] The olfactory material rapid switching device for home olfactory devices provided in the foregoing embodiments of the present invention has the following advantages:

[0055] 1. User-friendly switching mechanism: The primary target audience for home olfactory devices is the elderly. Therefore, every aspect of the device must be user-friendly to lower the barrier to entry. With socio-economic development and increasing material demands, modern industrial design increasingly focuses on essential human needs; thus, "human-centered" industrial design is receiving more and more attention in human society. Human-centered product design is an expression of humanistic spirit by industrial designers using aesthetic and ergonomic theories. However, many existing products do not consider the needs of the elderly, which is a core issue this technical solution addresses. Only by overcoming the challenge of user-friendliness for the elderly can the product truly become widespread among them, bringing the device to every household that needs it. The olfactory material quick-switching device in this application is simple to operate, convenient to switch between, and very easy for the elderly to use.

[0056] 2. Fast Switching Speed: For any product invention, the user experience determines its ability to attract more users. Therefore, this technical solution enables home olfactory devices to switch within seconds, significantly improving user experience and satisfaction. This differs from many current medical instruments, where most medical olfactory materials use integrated switching devices. These devices are complex to operate and difficult to restore to their original structure, making them unsuitable for home olfactory devices. Home olfactory devices need to be compact, convenient, simple, and user-friendly. The rapid olfactory material switching device provided in this application has a compact structure, small size, and fewer switching steps, solving these problems for home olfactory devices.

[0057] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0058] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
