Description

Technical Field

[0001] This utility model relates to the field of atomizer technology, and in particular to a handheld piezoelectric atomizer. Background Technology

[0002] Handheld piezoelectric nebulizers are portable devices widely used in medical care, home care, and personal health management. Their main function is to convert liquid medications into tiny particles, which are then inhaled and applied directly to the respiratory tract or lungs to treat or relieve symptoms. As people's demand for health management increases, the portability, safety, and ease of use of nebulizers have become key concerns for users. Traditional nebulizers often focus on atomization effects in their design, but have certain shortcomings in terms of sealing and ease of maintenance. In particular, the sealing of the liquid tank and the disassembly and cleaning of the mask can easily lead to liquid leakage or cleaning difficulties. Therefore, developing a nebulizer that combines efficient sealing and easy maintenance has become an important direction for current technological improvement.

[0003] In the present technology, handheld atomizers typically use simple threaded connections or snap-fit ​​structures to seal the liquid tank and the atomizer body. For example, the liquid tank's filling port is sealed with a threaded cap or rubber stopper, while the mask and the atomizer body are connected by a fixed snap or knob.

[0004] A significant problem with existing technologies is that when the nebulizer is tilted or accidentally dropped, the liquid in the reservoir is prone to leaking from the filling port. This is mainly because traditional sealing structures such as threaded caps or rubber stoppers cannot effectively maintain a seal when subjected to external impact or tilting, resulting in liquid overflow. Such leakage not only wastes medication but also pollutes the equipment or the surrounding environment, and even affects the user experience and safety. To address this issue, a handheld piezoelectric nebulizer is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a handheld piezoelectric atomizer, which aims to improve the problem of liquid overflow in the canister caused by the atomizer tilting or falling in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a handheld piezoelectric atomizer, including a handle, a start button provided on the outer wall of the handle, a liquid storage tank fixedly connected to the top of the handle, a fixing block fixedly connected to the top of the liquid storage tank, a flip cover rotatably connected to the outside of the fixing block, a sealing frame fixedly connected to the top of the flip cover, and a sealing component provided inside the sealing frame;

[0007] The sealing assembly includes a rubber gasket, the top of which is fixedly connected to the inside of the sealing frame. A locking block is fixedly connected to the outer wall of the flip-top cover. A fixing frame is fixedly connected to the outer wall of the liquid storage tank. A rotating column is fixedly connected inside the fixing frame. A locking plate is rotatably connected to the outer wall of the rotating column. The locking plate engages with the locking block. A spring is provided inside the locking plate. One end of the spring is fixedly connected to the inner wall of the locking plate, and the other end of the spring is fixedly connected to the outer wall of the liquid storage tank. A fixing column is fixedly connected to the outer wall of the liquid storage tank. A quick-release assembly is provided inside the fixing column.

[0008] As a further description of the above technical solution: the quick-release assembly includes a sliding post and a pin, the sliding post being slidably connected inside the fixed post, and the bottom of the pin being fixedly connected to the top of the sliding post.

[0009] As a further description of the above technical solution: a ring is fixedly connected to the outer wall of the sliding column, the ring is slidably connected inside the fixed column, and the pin is slidably connected inside the fixed column.

[0010] As a further description of the above technical solution: a first spring is sleeved on the outer wall of the sliding column, one end of the first spring is fixedly connected to the inside of the fixed column, and the other end of the first spring is fixedly connected to the bottom of the ring.

[0011] As a further description of the above technical solution: a trapezoidal column is slidably connected inside the fixed column, and a connecting column is fixedly connected to one end of the trapezoidal column.

[0012] As a further description of the above technical solution: a trapezoidal column 2 is slidably connected to the outer wall of the connecting column, and a face mask is fixedly connected to one end of the connecting column.

[0014] As a further description of the above technical solution: the trapezoidal column one and the trapezoidal column two are engaged, and the trapezoidal column two is slidably connected to the outer wall of the pin.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the flip cover rotates on the fixed block, so that the flip cover fits into the liquid storage tank. Then, the sealing frame and rubber gasket squeeze and seal the liquid inlet of the atomizer. Subsequently, the card plate and the card block engage, thereby achieving the effect of sealing the liquid inlet of the liquid storage tank of the atomizer. This solves the problem of liquid overflow caused by the atomizer tilting or falling, and improves the safety of the atomizer.

[0017] 2. In this utility model, by sliding the sliding column and the pin, and by contracting and releasing the elastic force of the first spring, and by sliding and squeezing the pin through the first trapezoidal column and the second trapezoidal column, the atomizer mask can be quickly installed and removed. This solves the problem that the traditional connection method between the atomizer and the mask makes it difficult to remove it for cleaning, and improves the convenience of atomizer maintenance.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 - Figure 3This utility model provides an embodiment of a handheld piezoelectric nebulizer, including a handle 1. A start button 2 is provided on the outer wall of the handle 1 to control the start and stop of the nebulizer for easy user operation. A liquid storage tank 3 is fixedly connected to the top of the handle 1. The liquid storage tank 3 is used to store liquid medicine and is one of the core components of the nebulizer. A fixing block 13 is fixedly connected to the top of the liquid storage tank 3. The fixing block 13 is used to support and fix the flip cover 4 to ensure its stable rotation. The flip cover 4 is rotatably connected to the outside of the fixing block 13. The flip cover 4 is used to seal the liquid inlet of the liquid storage tank 3 to prevent liquid medicine leakage. A sealing frame 7 is fixedly connected to the top of the flip cover 4. The sealing frame 7 is used to accommodate the sealing component to ensure the sealing effect. A sealing component is provided inside the sealing frame 7 to enhance the sealing of the liquid inlet.

[0026] The sealing assembly includes a rubber gasket 8, the top of which is fixedly connected inside the sealing frame 7. The rubber gasket 8 deforms to fit tightly against the filling port of the storage tank 3, preventing liquid leakage. A locking block 12 is fixedly connected to the outer wall of the flip cover 4, which cooperates with the locking plate 10 to fix the flip cover 4. A fixing frame 9 is fixedly connected to the outer wall of the storage tank 3, supporting the rotating column 11 to ensure its stable rotation. The rotating column 11 is fixedly connected inside the fixing frame 9, supporting the locking plate 10 so that it can rotate freely. The locking plate 10 is rotatably connected to the outer wall of the rotating column 11. The locking plate 10 engages with the locking block 12 to fix the position of the flip cover 4. The locking plate 10 engages with the locking block 12. A spring is provided inside the locking plate 10. One end of the spring is fixedly connected to the inner wall of the locking plate 10, and the other end of the spring is fixedly connected to the outer wall of the liquid storage tank 3. The spring is used to provide elastic force so that the locking plate 10 can automatically reset and engage with the locking block 12 to ensure the stability of the seal. A fixing post 5 is fixedly connected to the outer wall of the liquid storage tank 3. The fixing post 5 is used to support the quick-release assembly to realize the quick installation and removal of the mask 6. The fixing post 5 is provided with a quick-release assembly. The quick-release assembly is used to simplify the removal process of the mask 6 and facilitate cleaning and maintenance.

[0027] Specifically, when using the nebulizer, the liquid storage tank 3, as the storage container for the liquid, is crucial for its airtightness. To prevent leakage, the design employs a method where the flip-top 4 fits tightly against the top of the liquid storage tank 3. When the flip-top 4 is rotated to fully fit against the top of the liquid storage tank 3, the sealing frame 7 applies downward pressure, squeezing the rubber pad 8 and causing it to deform elastically, thus tightly fitting against the liquid inlet of the liquid storage tank 3 to form an effective seal. This process not only ensures that the liquid will not leak from the liquid inlet but also guarantees the hygiene and safety of the nebulizer during use. To further enhance the stability of the seal, a mechanism involving the locking plate 10 and the locking block 12 is used. After the flip-top 4 fits against the top of the liquid storage tank 3, the user can rotate the locking plate 10, causing it to rotate on the rotating column 11. At this time, the spring inside the locking plate 10 releases its stored elasticity, pushing the locking plate 10 to quickly return to its original position and precisely engage with the locking block 12.

[0028] Reference Figure 4The quick-release assembly includes a sliding post 18 and a pin 16. The sliding post 18 is slidably connected inside the fixed post 5 and is used to drive the pin 16 to move up and down, enabling the quick removal of the face mask 6. The bottom of the pin 16 is fixedly connected to the top of the sliding post 18. The pin 16 is used to cooperate with the trapezoidal post 15 during sliding to control the fixing and releasing of the face mask 6. A ring 20 is fixedly connected to the outer wall of the sliding post 18. The ring 20 is slidably connected inside the fixed post 5. The ring 20 is used to limit the range of movement of the sliding post 18 and ensure its stability. The pin 16 is slidably connected inside the fixed post 5. The pin 16 cooperates with the trapezoidal post 15. To achieve locking and unlocking of the face mask 6, a first spring 17 is sleeved on the outer wall of the sliding post 18. One end of the first spring 17 is fixedly connected to the inside of the fixed post 5, and the other end of the first spring 17 is fixedly connected to the bottom of the ring 20. The first spring 17 is used to provide elastic force so that the sliding post 18 can automatically reset, ensuring the ease of operation of the quick-release assembly. Trapezoidal post 14 is slidably connected inside the fixed post 5. Trapezoidal post 14 is used to cooperate with trapezoidal post 25 to achieve fixing and disassembly of the face mask 6. A connecting post 19 is fixedly connected to one end of trapezoidal post 14. The connecting post 19 is used to connect trapezoidal post 14 and trapezoidal post 25 to ensure synchronous movement of the two. A trapezoidal column 2 15 is slidably connected to the outer wall of the connecting column 19. The trapezoidal column 2 15 is used to cooperate with the pin 16 to control the fixed state of the mask 6. The mask 6 is fixedly connected to one end of the connecting column 19. The mask 6 is used to deliver the atomized medicine to the user's mouth and nose and is an important part of the nebulizer. One side of the mask 6 is slidably connected to the inside of the fixing column 5. The mask 6 is connected and separated from the fixing column 5 by sliding. The trapezoidal column 2 15 is slidably connected to the inside of the fixing column 5. The trapezoidal column 2 15 is locked and unlocked to the mask 6 by cooperating with the pin 16. The trapezoidal column 1 14 and the trapezoidal column 2 15 are engaged. The engagement of the trapezoidal column 1 14 and the trapezoidal column 2 15 is used to ensure the stability of the mask 6 in the fixed state. The trapezoidal column 2 15 is slidably connected to the outer wall of the pin 16. The trapezoidal column 2 15 is slidably engaged with the pin 16 to achieve quick disassembly and installation of the mask 6.

[0029] Specifically, after prolonged use of the atomizer, regular cleaning of the mask 6 is essential to ensure hygiene and proper equipment operation. The process of disassembling the mask 6 is designed to be both simple and efficient. First, the user simply pushes the mask 6 gently, allowing it to move smoothly into the fixing post 5. This action causes the trapezoidal post 15 to slide synchronously into the fixing post 5. During the sliding process, the trapezoidal post 15 gradually presses against the pin 16, causing it to retract into the fixing post 5, thus creating space for the disassembly of the mask 6. Once the trapezoidal post 15 has completely slid past the pin 16, the user simply pulls the mask 6 outwards, and the trapezoidal post 15 continues to slide, eventually disengaging from the pin 16. This process is not only smooth and natural but also fully considers the user's operating experience, avoiding the tediousness or effort required for disassembly. Through this design, the mask 6 can be easily separated from the fixing post 5, facilitating thorough cleaning and disinfection by the user.

[0030] Working principle: When the nebulizer is in use, and the liquid reservoir 3 contains medication, to prevent leakage, the flip-top cover 4 is rotated to seal the top of the reservoir 3. When the flip-top cover 4 is in contact with the top of the reservoir 3, the sealing frame 7 presses down on the rubber pad 8, causing the rubber pad 8 to deform and seal against the liquid inlet of the reservoir 3. At this time, the locking plate 10 rotates on the rotating column 11, and then the spring inside the locking plate 10 releases its elasticity, causing the locking plate 10 to reset and engage with the locking block 12. This achieves the purpose of preventing leakage of the liquid medicine inside the atomizer. When the atomizer needs to be removed and cleaned after long-term use, the mask 6 is pushed into the fixed post 5. The mask 6 causes the trapezoidal post 15 to slide into the fixed post 5. At the same time, the trapezoidal post 15 squeezes the pin 16 and retracts into the fixed post 5. After the trapezoidal post 15 slides past the pin 16, the mask 6 is pulled outward to make the trapezoidal post 15 slide past the pin 16, thus achieving the purpose of removing and cleaning the mask 6.
