Description

Technical Field

[0001] This invention relates to the field of atomization technology, and in particular to a nano-silver sustained-release particle, its preparation method, and a self-cleaning mask atomizer. Background Technology

[0002] Air pollution and seasonal changes often lead to hospitals being packed with patients suffering from respiratory illnesses. Traditional treatment methods involving medication and injections are insufficient to meet the diverse needs of patients with complex conditions.

[0003] A nebulizer, also known as a nebulizer machine or expectorant machine, is a device used to assist in the treatment of upper respiratory tract diseases. It primarily uses nebulized inhalation; the compressed air generated by the nebulizer atomizes the medication solution into tiny particles, which are then inhaled into the respiratory tract and lungs, where they deposit. This allows the medication to quickly and directly reach the affected area and come into direct contact with the diseased tissue, resulting in rapid onset of action. This achieves a rapid and effective therapeutic effect. It eliminates the time required for oral or injectable blood routes, and the small dose is sufficient to achieve the desired effect, avoiding and reducing systemic medication and the side effects of the drug itself. This is especially important for infants, children, and the elderly.

[0004] Currently, in hospitals, clinics, and homes, the nebulizer cups, nebulizer devices, masks, and connectors used with nebulizers are either disposable or sterilized by boiling. The former, disposable use, has a significant impact on raw material requirements and the environment. The latter, boiling, is also very inconvenient and unlikely to effectively kill germs, potentially even damaging the nebulizer cup's nebulization function. Summary of the Invention

[0005] The purpose of this invention is to provide nano-silver sustained-release particles, a preparation method, and a self-cleaning mask atomizer, aiming to solve the problem that existing atomizers cannot effectively kill bacteria through disinfection methods.

[0006] In a first aspect, embodiments of the present invention provide a nano-silver sustained-release particle, the nano-silver sustained-release particle being composed of 0.1%-5% silver powder, 20%-50% sodium hexametaphosphate, 30%-50% calcium acetate, 1%-10% zinc oxide and 10%-20% sodium polyacrylate.

[0007] In a second aspect, embodiments of the present invention provide a method for preparing nano-silver sustained-release particles as described in the first aspect, comprising:

[0008] Sodium hexametaphosphate and sodium polyacrylate were dissolved in water and stirred until well mixed to obtain the first solution;

[0009] Zinc oxide and silver powder are added to the first solution and mixed and dispersed to obtain the second solution;

[0010] Add calcium acetate to the second solution and stir at 60-90℃ for 20-24 hours to obtain semi-finished nano-silver sustained-release particles;

[0011] The semi-finished nano-silver sustained-release particles were rinsed and purified with deionized water, and then dried at 120-150℃ for more than 4 hours to obtain the final nano-silver sustained-release particles.

[0012] Thirdly, embodiments of the present invention provide a self-cleaning mask atomizer, comprising:

[0013] The device comprises a neckband, a connector, and a mask. The neckband is equipped with an atomizing cup, a slow-release component, and an atomizing device. One end of the slow-release component is connected to the atomizing cup, and the other end of the slow-release component is connected to one end of the atomizing device. The other end of the atomizing device is connected to the mask via the connector. The atomizing cup, the slow-release component, the atomizing device, the connector, and the mask are sequentially connected. The slow-release component contains nano-silver slow-release particles as described in the first aspect. When the liquid in the atomizing cup flows through the nano-silver slow-release particles, the nano-silver slow-release particles release sterilizing substances, thereby cleaning and antibacterially treating the atomizing cup, the slow-release component, the atomizing device, and the connector.

[0014] This invention discloses a nano-silver sustained-release particle, its preparation method, and a self-cleaning mask atomizer. The nano-silver sustained-release particle is composed of 0.1%-5% silver powder, 20%-50% sodium hexametaphosphate, 30%-50% calcium acetate, 1%-10% zinc oxide, and 10%-20% sodium polyacrylate. The nano-silver sustained-release particle of this invention has advantages such as safety, long-lasting antibacterial properties, broad-spectrum antibacterial activity, and good sterilization effect. Its preparation method does not require advanced equipment or complex processes, has low production costs, and is simple to operate with high preparation efficiency. The liquid in the mask atomizer using the nano-silver sustained-release particle can generate an antibacterial water body with ppb-level silver ions. This antibacterial water body can efficiently clean and antibacterially treat the atomizing cup, mask, atomizing device, and connectors. Simultaneously, the antibacterial water body will not damage the atomizing function of the atomizing device. The silver ions remaining on the surface after rinsing the mask atomizer with clean water can also keep the atomizing device clean for a long time, further enhancing its practicality.

[0033] This preparation method does not require advanced equipment or complex processes, has low production costs, simple operation, and high preparation efficiency.

[0034] It should be noted that the size of the nano-silver sustained-release particles can be controlled by the stirring reaction time and subsequent grinding process, with particle sizes ranging from rice grain type (1-2mm) to tablet type (4-6mm). Among them, the rice grain type nano-silver sustained-release particles can be fixed in the sustained-release component in the mask atomizer and slowly release low concentrations of silver ions during use. Furthermore, the rice grain type nano-silver sustained-release particles in the sustained-release component can be replaced periodically to ensure the concentration of silver ions and the antibacterial effect.

The results are shown in Table 1. In the table, the average number of recovered colonies of the test samples refers to the average number of recovered colonies of the samples prepared in each group of embodiments.

[0099] Table 1

[0100]

[0101] This demonstrates that water treated with nano-silver slow-release particles has a good antibacterial effect; at the same time, the silver ion content in the water is less than 0.03 mg / L, which meets drinking water standards and is safe for human consumption.

[0102] Please see Figure 2-4 The present invention also provides a self-cleaning mask atomizer, comprising: a neck hanger 1, a connector 2, and a mask 3. The neck hanger 1 is provided with an atomizing cup 4, a slow-release component 5, and an atomizing device 6. One end of the slow-release component 5 is connected to the atomizing cup 4, and the other end of the slow-release component 5 is connected to one end of the atomizing device 6. The other end of the atomizing device 6 is connected to the mask 3 through the connector 2. The atomizing cup 4, the slow-release component 5, the atomizing device 6, the connector 2, and the mask 3 are connected in sequence. The slow-release component 5 is provided with nano-silver slow-release particles 7 as described in the above embodiment. When the liquid in the atomizing cup 4 flows through the nano-silver slow-release particles 7, the nano-silver slow-release particles 7 release sterilizing substances, thereby cleaning and antibacterially treating the atomizing cup 4, the slow-release component 5, the atomizing device 6, and the connector 2.

[0103] This embodiment adds a slow-release component 5 between the atomizing cup 4 and the atomizing device 6, and fills the slow-release component 5 with nano-silver slow-release particles 7. This allows the liquid in the atomizing cup 4 to react with the nano-silver slow-release particles 7 to generate an antibacterial water body with ppb-level silver ions. This antibacterial water body can efficiently clean and antibacterially treat the atomizing cup 4, the mask 3, the atomizing device 6, and the connector 2. The neckband 1 design can meet the requirements of power supply and circuit settings, as well as the setting of the small atomizing device 6. Moreover, the neckband 1 design allows most of the weight of the atomizer to be applied to the user's torso, reducing the force of the mask 3 on the user's ears and improving the user experience. At the same time, compared with traditional desktop atomizers, the connector 2 of the atomizer in this embodiment is shorter. The shorter connector 2 ensures efficient gas delivery over short distances, reducing waste such as sticking to the wall. In addition, the shorter connector 2 is easy to clean and less prone to bacterial growth.

[0104] Its working principle is as follows: When the atomizing cup 4 is filled with liquid medicine, since the atomizing cup 4 is connected to the slow-release component 5, the liquid medicine will flow into the slow-release component 5 and submerge the nano-silver slow-release particles 7. At this time, the nano-silver slow-release particles 7 will slowly release ppb-level silver ions into the liquid medicine. When the user needs to atomize, the atomizing device 6 uses the vibration generated by piezoelectricity to make the liquid medicine with ppb-level silver ions pass through the mesh and form tiny droplets. These tiny droplets are further dispersed into fine atomized particles by the action of turbulence or airflow, flow through the connector 2 and through the mask 3 into the human body. While the liquid medicine is flowing, it can clean, descale and inhibit bacteria of the atomizing cup 4, slow-release component 5, atomizing device 6, connector 2 and mask 3.

[0105] In order to reduce drug residue in the nebulizer, the sustained-release component 5 in this embodiment is located below the nebulizer cup 4. When the human body wears the neck strap 1 around the neck, the nebulizer cup 4 tilts downward, so that the drug liquid is close to the sustained-release component 5 and the nebulizer device 6 below, thereby effectively reducing the drug residue in the cup.

[0106] Furthermore, in this embodiment, the atomizing cup 4 is detachably mounted on the neck hanger 1. The detachable structure of the atomizing cup 4 means that when the atomizing cup 4 is damaged, it can be disassembled and replaced with a new atomizing cup 4, thereby reducing maintenance costs. At the same time, the detachable structure allows the atomizing cup 4 to be customized according to the user's individual needs.

[0107] The detachable connection between the atomizing cup 4 and the neck hanger 1 can be achieved by screws and threaded holes, by snap-fit, or by setting a magnet on both the atomizing cup 4 and the neck hanger 1, and achieving a detachable connection between the atomizing cup 4 and the neck hanger 1 by the attraction of the two magnets.

[0108] In this embodiment, a battery assembly (not shown in the figure) is also provided on the neck strap 1. The battery assembly is electrically connected to the atomizing device 6. The battery assembly is mainly used to power the electronic equipment in the atomizer. At the same time, it makes it easier for users to carry the atomizer and use it anytime and anywhere.

[0109] Furthermore, to balance the weight at both ends of the atomizer and prevent one side from being too heavy, causing severe stress on one side when the user wears it, thus resulting in a poor wearing experience, the battery assembly in this embodiment is located at one end of the neckband 1, and the atomizing cup 4, the slow-release assembly 5, and the atomizing device 6 are located at the other end of the neckband 1. Through the above structural arrangement, this embodiment ensures that the weight difference between the two ends of the atomizer is always within a predetermined range, thereby improving the user's wearing experience.

[0110] Furthermore, this embodiment also includes a charging port 8 (e.g., Figure 2 As shown, the charging port 8 is used to charge the battery assembly. It can be a USB interface, a Type C interface, or a Lightning interface.

[0111] In this embodiment, the neck strap 1 is provided with an interface 9 (such as...). Figure 2 As shown, the atomizing device 6 is connected to the connector 2 via the interface 9. The atomizing device 6, the interface 9, and the connector 2 are connected in sequence. The interface 9 allows for a better connection between the neckband 1 and the connector 2. However, during long-term use, the connection between the connector 2 and the neckband 1 may become loose. In this case, the problem of loose connection can be solved by replacing the connector 2 or the corresponding interface 9.

[0112] In this embodiment, the neckband 1 is equipped with a control circuit, which is electrically connected to the atomizing device 6 and the battery assembly. The control circuit is mainly used to control the operating parameters of the atomizing device 6, such as atomization time and atomization intensity. The control circuit can interact with the user through buttons, knobs, or other control interfaces. Please refer to [link to relevant documentation]. Figure 2 This embodiment also includes an atomization time control component 10 and an atomization intensity control component 11, both of which are electrically connected to the control circuit. Users can adjust the atomization time and atomization intensity according to their own needs through the atomization time control component 10 and the atomization intensity control component 11 respectively.

[0113] The following is a detailed explanation of mask 3:

[0114] Please see Figure 4 To improve the airtightness of the mask 3, a silicone coating 12 is provided at the edge of the mask 3 in this embodiment. Since the silicone coating 12 has high elasticity and sealing performance, it can ensure that the mask 3 fits the human face completely, preventing gas from entering the inside of the mask 3, thereby ensuring that the medicine can effectively enter the human body and further ensuring the effect of the medicine on the human body. Moreover, since the silicone coating 12 has good resilience, it can reduce wear on the edge of the mask 3, thereby extending its service life. Secondly, the silicone coating 12 can also provide a softer touch; the softness of this material can make the person wearing the mask 3 feel more comfortable.

[0115] Existing handheld portable nebulizers require users to hold the mask 3 for extended periods, which can cause muscle soreness in the user's hands and result in a poor user experience. To improve the user experience, the mask 3 in this embodiment is provided with an ear loop structure 13 on its edge. Users can wear the mask 3 on their face through the ear loop structure 13 without holding the mask 3, effectively freeing their hands, improving convenience, and reducing the impact of routine treatment on daily life.

[0116] The mask 3 in this embodiment is also provided with a mask interface 14 that is connected to the connector 2. The function and effect of the mask interface 14 are similar to those of the interface 9, and will not be described in detail here.

[0117] The mask 3 in this embodiment is also provided with a ventilation hole 15. The ventilation hole 15 allows outside air to enter at the same time as the human body inhales the atomized medicine, so as to deliver the atomized medicine to a deeper part of the human mouth and further increase the treatment effect.

[0118] It should be noted that the atomizing cup 4, the slow-release component 5, the atomizing device 6, the interface 9, the connector 2, and the mask 3 in the above embodiments can all be replaced individually, reducing replacement costs and improving replacement efficiency. In daily use, water can be directly injected into the atomizer with all components connected, fully immersing the slow-release component. Turning on the atomizing device normally and generating atomized droplets can effectively deliver droplets containing ppb-level silver ions to the mask, completing the overall antibacterial cleaning.

[0119] The nebulizer in this embodiment can also be used for patients with allergic rhinitis. Patients with allergic rhinitis also need to undergo routine nebulization, but they do not necessarily need to use special drugs. Instead, they can use saline or purified water to form a nebulizer to help the mucosa recover. These patients can better protect their mucosa by using the nebulizer. At the same time, the nano-silver sustained-release particles 7 and the sustained-release component 5 can effectively generate antibacterial water with ppb-level silver ions. After being nebulized and inhaled into the nasal cavity, it can more effectively protect the damaged mucosa.

[0120] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims.

[0121] It should also be noted that, in this specification, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusivity.

[0122] The term "comprises" implies that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprises a..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
