Description

Technical Field

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

[0002] Medical nebulizers are primarily used to treat various upper and lower respiratory system diseases, such as colds, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis, and other diseases occurring in the trachea, bronchi, alveoli, and pleural cavity. Nebulized inhalation therapy is an important and effective treatment method for respiratory diseases. A nebulizer atomizes medication into tiny particles, which are then inhaled and deposited in the respiratory tract and lungs, achieving a painless, rapid, and effective treatment.

[0003] Chinese patent document CN118178802A discloses an improved nebulizer, which mainly includes a nebulizer body and a nebulizing cup that cooperates with the nebulizer body. The nebulizer body and the nebulizing cup are connected by a flexible tube. The defects and shortcomings of this improved nebulizer are: (1) The overall volume of this improved nebulizer is large and bulky, making it inconvenient for patients to move when using it; (2) The nebulizer body and the nebulizing cup of this improved nebulizer are designed separately and connected by a flexible tube. However, there is a pressure loss when the compressed air generated by the nebulizer body is delivered in the flexible tube, resulting in a large diameter of the nebulized drug particles and poor therapeutic effect.

[0004] Therefore, there is an urgent need to provide a handheld nebulizer with smaller and more uniform mist particle diameter and better therapeutic effect. Utility Model Content

In this document, directional terms such as "front," "rear," "left," "right," "up," and "down" are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.

[0039] Example 1:

[0040] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This embodiment provides a handheld atomizing device, including an atomizing host 1 and an atomizing cup 2.

[0041] The top of the atomizing host 1 is provided with a first plug-in structure and a first air passage structure that connects the high-pressure gas generated by the atomizing host 1 to the atomizing cup 2;

[0043] Specifically, in this embodiment, the atomizing host 1 includes a cylindrical housing 102, a top cover 103, a base 101, and a compressor pump 104; the cylindrical housing 102 has openings on both the upper and lower sides, and the top cover 103 and the base 101 are respectively installed in the openings; the compressor pump 104 is installed inside the cylindrical housing 102, and the compressor pump 104 has an air inlet end and an air outlet end, and the air outlet end is connected to the first air passage structure; the first plug-in structure is provided on the top cover 103.

[0044] Furthermore, the first insertion structure is an annular groove 109 opened on the top surface of the upper cover 103, and the first air passage structure is a socket 110 opened on the upper cover 103 and connected to the air outlet.

[0045] In this embodiment, the atomizing cup 2 includes a cup body 201 and a cup lid 202 optionally disposed on the cup body 201. The inside of the cup body 201 has a liquid storage chamber 206. An air inlet pipe 204 extending vertically is provided on the bottom wall of the cup body 201. The air inlet pipe 204 has an integrally formed upper pipe section 209 and a lower pipe section 210. The upper pipe section 209 extends vertically upward into the liquid storage chamber 206, and the lower pipe section 210 extends vertically downward into the socket hole 110. The bottom of the cup body 201 is integrally formed with a second insertion structure.

[0046] Furthermore, the second insertion structure is a connecting tube wall 208 formed on the bottom surface of the cup body 201.

[0047] Preferably, the first insertion structure is an annular groove 109, and the second insertion structure is a connecting tube wall 208 formed by extending downward from the bottom edge of the cup body 201. The connecting tube wall 208 is inserted into the annular groove 109 and is detachably connected to the top cover 103.

[0048] In this embodiment, the handheld nebulizer is designed as a single unit, which reduces its overall size and makes it easier for patients to hold and use. In addition, it eliminates the intermediate air supply pipeline, and the nebulizer 1 directly delivers compressed air to the medicine chamber 206 inside the nebulizer 2. There is no pressure loss, so the nebulized medicine droplets are smaller and more uniform, resulting in better treatment effect.

[0049] Please see Figure 2 and Figure 4 The lower part of the connecting tube wall 208 is provided with multiple clips 203, and the annular groove 109 is provided with a corresponding slot for each clip 203. The clips 203 are inserted into the slots one by one and engage with the slots.

[0054] The working process of the handheld nebulizer in this embodiment is as follows: The nebulizer host 1 delivers high-pressure gas into the nebulizer cup 2 through the compressor pump 104. The high-pressure gas enters the medicine chamber 206 inside the nebulizer cup 2 and atomizes the medicine in the medicine chamber 206. Then, it enters the mask through the mist outlet tube 207 and is finally inhaled into the mouth and nose by the patient.
