Technical Field

[0001] The invention belongs to the technical field of nasal cavity care, and particularly relates to a heatable atomizer. Background Art

[0002] Micromesh nebulizers, as a tool for aerosol therapy, have become increasingly well-known. Current nebulizers are designed to atomize medications directly into the respiratory tract. Large amounts of room-temperature mist, when inhaled into the respiratory tract, can cause extreme discomfort, even leading to negative physiological reactions such as coughing and accelerated breathing. This significantly impacts the user experience and reduces the effectiveness of treatment, potentially leading to other complications and rendering the nebulizer ineffective.

[0023] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0024] like Figures 1 to 5 As shown, a heatable atomizer includes a main unit 1, a liquid medicine cup 3 arranged on the main unit 1 and a mist outlet nozzle 2 arranged on the liquid medicine cup 3.

[0025] The host 1 is provided with a host electrode 8, and the medicine cup 3 is provided with a liquid outlet and a medicine cup electrode 7 located on one side of the liquid outlet. An atomizer 4 is provided at the liquid outlet of the medicine cup 3, and the mist outlet nozzle 2 is provided on the medicine cup 3 and fixes the atomizer 4 therebetween. The atomizer 4 atomizes the medicine liquid from the liquid outlet, and the atomizer enters the user's respiratory tract through the mist outlet nozzle 2. When the atomizer 4 is installed, its electrode is electrically connected to the medicine cup electrode 7 on the medicine cup 3. A receiving groove is also provided at the rear of the mist outlet nozzle 2, and an annular heating device 5 is provided in the receiving groove. The annular heating device 5 is provided in front of the atomizer 4. The annular heating device 5 has a heating channel 6, so that the medicine mist is heated to a suitable temperature in the process of passing through the heating channel 6. The annular heating device 5 is powered by the host 1.

[0026] In one embodiment, the annular heating device 5 includes an insulating sleeve 501 and an electric heating coil 502. The electric heating coil 502 is disposed within the insulating sleeve 501. The ends of the electric heating coil 502 are not connected to each other, and heating electrodes 508 are provided at both ends. After the annular heating device 5 is installed, the heating electrodes 508 are also electrically connected to the medicine cup electrodes 7 on the medicine cup 3. When energized, the electric heating coil 502 generates heat, thereby heating the medicine mist.

[0027] like Figure 5 As shown, in one embodiment, the electric heating coil 502 includes several heating straight plates 509 distributed along a circumferential direction. The leading edges of two adjacent heating straight plates 509 are connected by a front connecting curved plate 511, and the trailing edges are connected by a rear connecting curved plate 510. The coil formed by the heating straight plates 509 and the connecting curved plates has a larger contact area than traditional electric heating coils, thereby improving heating efficiency. It should be noted that because the electric heating coil 502 requires electricity, the rear portions of two adjacent heating straight plates 509 are disconnected and each is connected to a heating electrode 508. These two disconnected heating straight plates 509 constitute the front and rear ends of the entire electric heating coil 502. It should be noted that the thickness of the heating straight plates 509 and the connecting curved plates are both relatively small, and the electric heating coil 502 can be formed by an "S"-shaped plate of a certain width arranged in a circle along a circumference.

[0028] For ease of manufacturing, in one embodiment, the surfaces of the heating plates 509 are parallel to the central axis of the heating channel 6. Furthermore, the heating plates 509 are evenly distributed along the circumference, and the heating electrodes 508 are located at the front and rear ends of the heating plates 509 near the outer edges.

[0029] In order to increase the contact area with the medicine mist, the electric heating coil 502 should have a larger size not only in the axial direction but also in the radial direction. Figure 5 As shown, in one embodiment, the radial dimension W of the heating straight plate 509 is 0.5 to 1 times the radius R of the heating channel 6, and the preferred value is 1 times.

[0030] Because the electric heating coil 502 has a certain radial dimension, the connecting bent plate will block the movement of the medicine mist, thereby affecting the mist output effect. In one embodiment, the front and rear connecting bent plates 511 and 510 are each provided with a plurality of through holes 507 distributed radially. Through these through holes 507, the medicine mist can be directly transported forward through the through holes 507, improving the mist output effect.

[0031] To quickly secure the heating coil 502 within the thermal sleeve 501 when replacing it, in one embodiment, the inner wall of the thermal sleeve 501 is provided with a plurality of front limiting posts 503 and rear limiting posts 504. The front limiting posts 503 are located behind the corresponding front connecting bent plates 511, while the rear limiting posts 504 are located in front of the corresponding rear connecting bent plates 510. Once the heating coil 502 is installed, its rearward movement is restrained by the front limiting posts 503, while its forward movement is restrained by the rear limiting posts 504.

[0032] In order to prevent the heating electrode 508 from short-circuiting when it encounters water, Figure 4 As shown, in one embodiment, the heat-insulating sleeve 501 is provided with an electrode holder 505, which is provided with a fixing hole 506 for the heating electrode 508 to pass through. After the electric heating coil 502 is installed, the base of the heating electrode 508 is completely set in the fixing hole 506, and the head of the heating electrode 508 extends out of the fixing hole 506 to connect with the medicine cup electrode 7.

[0033] To achieve temperature feedback, in one embodiment, a temperature sensor for detecting the heating temperature is further included. The temperature sensor feeds back a temperature signal to the host for adjusting the temperature of the annular heating device 5. It should be noted that the temperature sensor can be located within the heating channel 6 or on the inner wall of the mist outlet nozzle 2. It is connected to the internal control circuit of the host 1 to achieve temperature feedback. The control process is conventional and will not be described in detail.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
