Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an atomizing muffler and an atomizing structure comprising the muffler. Background Art

[0002] With the continuous development of medical technology, the use of nebulizers to treat patients with respiratory diseases has become a common treatment method. Compared with the traditional method of taking medicine to treat respiratory diseases, medical nebulizers can atomize the liquid medicine into tiny particles, and the medicine enters the respiratory tract and lungs through inhalation, thereby achieving painless, rapid and effective treatment.

[0003] Medical nebulizers belong to Class II medical devices. Currently, there are two commonly used medical nebulizers: ultrasonic nebulizers and air compression nebulizers. Among them, compression nebulizers are widely used. However, compressed air nebulizers will generate noise during operation. Through research, it is found that the noise mainly comes from the vibration of the compressor and the noise of the airflow. Excessive noise will affect the patient's treatment mood. At present, the nebulizer is optimized by two methods: shock absorption and silencer, that is, by setting a fixed structure or a limit structure on the compressor to reduce its vibration and thus reduce the noise or by filtering silencer cotton to silence it. However, when the compression nebulizer is optimized by shock absorption, it can be found that the compression nebulizer still has a certain noise; when the silencer is silenced by filtering silencer cotton, due to the characteristics of the filter silencer cotton material, dust particles are easy to clog the pores during use, affecting the flow and atomization effect, causing pollution, and the silencer effect gradually weakens with the use time. Therefore, the silent design of the compressed air nebulizer is still an important focus in product design.

[0004] The utility model provides an atomizing silencer and an atomizing structure comprising the silencer, so as to solve the problem in the prior art that the atomizer has a large noise and affects the treatment mood of the patient. Utility Model Content

[0005] The utility model aims to provide an atomizing silencer and an atomizing structure including the silencer, so as to solve the problem in the prior art that the atomizer has a large noise and affects the treatment mood of the patient.

[0006] The technical solution of the utility model is: an atomizing silencer, including a shell formed by snapping, wherein a first cavity and a second cavity with relatively independent spaces are arranged in the shell; the first cavity corresponds to a first air inlet end and a first air outlet end connected to each other, and the second cavity corresponds to a second air inlet end and a second air outlet end connected to each other; wherein the first cavity and the second cavity are separated by a non-planar barrier portion.

[0007] Preferably, the blocking portion is in a stepped shape, and part of the inner walls of the first cavity and the second cavity are configured in a stepped shape.

[0011] Preferably, the gas filter is arranged at the first air inlet end; preferably, the housing comprises a first housing and a second housing which are buckled with each other;

Therefore, they cannot be understood as limitations on the present invention.

[0033] An atomizing silencer comprises a shell 1 formed by snapping together; Figure 1 , Figure 2 As shown, the housing 1 includes a first housing 11 and a second housing 12 that are interlocked; a first air inlet end 2 and a second air outlet end 3 are distributed on the first housing 11; and the first air inlet end 2 and the second air outlet end 3 are sunken into the first housing 11 to form a cylindrical cavity 22; a gas filter 21 is provided on the first air inlet end 2, and the gas filter 21 is embedded in the cylindrical cavity 22; Figure 3 , Figure 4 , Figure 5 As shown, the end face of the second shell 12 relative to the first air inlet end 2 and the second air outlet end 3 is planar, and the first air inlet end 2 and the second air outlet end 3 are partially convexly arranged, and the first air outlet end 5 and the second air inlet end 4 are arranged on the side wall of the convex structure; and the first air outlet end 5 and the second air inlet end 4 are arranged on the side of the convex structure that is biased toward the planar end face of the second shell 12.

[0034] In other embodiments, the first air outlet port 5 and the second air inlet port 4 are disposed on the second shell 12 , and their ports may face other directions under the condition that installation requirements are met.

[0035] like Figure 6As shown, a first cavity 7 and a second cavity 8 with relatively independent spaces are provided in the shell 1; the first cavity 7 is correspondingly connected to the first air inlet end 2 and the first air outlet end 5, and the second cavity 8 is correspondingly connected to the second air inlet end 4 and the second air outlet end 3; wherein, the first cavity 7 and the second cavity 8 are separated by a non-planar barrier 9. The barrier 9 is in a stepped shape, and part of the inner walls of the first cavity 7 and the second cavity 8 are configured in a stepped shape. A plurality of baffles 6 are provided inside the second cavity 8 to slow down the gas flow rate and reduce the energy of the sound wave. In addition, the side wall 71 of the first cavity 7 close to the first air inlet end 2 and the side wall 81 of the second cavity 8 close to the second air outlet end 3 are both arc-shaped structures, and the bottom wall 72 of the first cavity 7 close to the second air outlet end 3 is a streamlined structure.

[0036] In other embodiments, the baffle 6 may be disposed in the first cavity 7 ; or the baffle 6 may be disposed in both the first cavity 7 and the second cavity 8 .

[0037] like Figure 7 , Figure 8 As shown, the gas flows into the first cavity 7 from the first air inlet end 2, flows through the first air outlet end 5 and enters the connecting device. The gas output by the connecting device enters the second cavity 8 from the second air inlet end 4 and flows out from the second air outlet end 3. The first box body 11 and the second box body 12 are assembled into a closed structure by buckling 1 to form an atomizing silencer.

[0041] After being filtered by the gas filter 21, the air enters the first cavity 7 of the atomizing silencer from the first air inlet end 2. After passing through the first cavity 7, the filtered air enters the atomizing structure through the first air outlet end 5, the interface connecting pipe and the air inlet of the atomizing structure; the gas processed by the atomizing structure enters the second cavity 8 through the air outlet of the atomizing structure, the interface connecting pipe and the second air inlet end 4 of the atomizing silencer; after passing through the airway circulation path formed by multiple baffles and the side wall 81 of the arc structure in the second cavity 8, the gas with constant pressure and flow is output through the second air outlet end 3.
