Description

Technical Field

[0001] The utility model relates to an air pump device, in particular to a noise reduction structure of the air pump device. Background Art

[0002] In the prior art, air pump devices generate noise during operation. The root cause of the noise generated by air pumps involves multiple factors, including the moving parts inside the air pump, such as the piston, rotor or diaphragm, which may cause vibration and vibration during operation; or the pressure waves and gas vibrations generated by the air pump when compressing or moving the gas are transmitted through the gas and converted into sound. For small air pump devices, which are generally used in indoor environments, the noise caused by the operation of the air pump is more disturbing and affecting the user, such as household atomizers.

[0003] Nebulizer is an application of air pump device. Nebulizer is mainly used to treat various upper and lower respiratory system diseases, such as cold, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis and other diseases occurring in trachea, bronchi, alveoli and chest cavity. Nebulizer inhalation therapy is an important and effective treatment method for respiratory diseases. Nebulizer inhaler is used to atomize the liquid medicine into tiny particles. The medicine enters the respiratory tract and lungs through breathing and inhalation, thus achieving the purpose of painless, rapid and effective treatment.

[0004] During the use of the existing atomizer, the internal air pump generates a large noise when it is started, and the noise may affect the user's rest;

[0005] In addition, the air pump will generate heat during operation, and if this heat cannot be effectively discharged to the outside, it may cause damage to the internal electrical components. Utility Model Content

[0006] Based on the defects of existing atomizers, this article introduces a noise reduction structure for an air pump device, which aims to solve the problems that during the use of existing atomizers, the internal air pump will generate loud noise when starting, which may affect the user's rest, and the air pump will generate heat during operation, which may cause damage to the internal electrical components if it cannot be effectively discharged to the outside.

[0007] The technical solution adopted by the utility model is: a noise reduction structure of an air pump device, comprising an atomizer shell, the top of the atomizer shell is rotatably connected with the atomizer shell flip cover, a partition is arranged inside the atomizer shell, the partition divides the internal space of the atomizer shell into an upper accommodating space and a lower accommodating space, ventilation holes are opened on the surface of the partition, and the atomizer shell is provided with air inlets on the outer walls on both sides of the upper accommodating space; an air pump device is installed in the lower accommodating space, and a fan is arranged at the bottom of the air pump device.

[0008] Furthermore, a storage box is arranged in the upper accommodating space, and the storage box is mounted in the upper accommodating space, and the bottom and side of the storage box respectively form gaps with the partition and the inner side of the upper accommodating space of the atomizer shell for heat dissipation airflow to flow.

[0009] Furthermore, a limiting groove is provided at the bottom of the storage box so that the storage box can be mounted in the upper accommodating space.

[0010] Furthermore, a limiting block is arranged inside the upper accommodating space, and the storage box is mounted on the limiting block.

[0011] Compared with the prior art, this application has the following beneficial effects:

[0012] 1. The partition is used to separate the interior of the atomizer shell into two spaces, the upper and the lower space, which is equivalent to sealing the air pump device in the lower space to a certain extent. Only the ventilation holes of the partition can transmit the sound of the air pump. However, a storage box is set on the partition so that the ventilation holes will not be directly exposed to the outside, thereby blocking the sound transmitted from the ventilation holes to a certain extent, reducing the noise generated by the air pump to a certain extent.

[0013] 2. An air inlet is opened in the upper space through the atomizer shell, and a fan is provided at the bottom of the air pump device in the lower space. When the fan is running, airflow will flow in from the air inlet in the upper space, flow through the gap in the side wall, and then flow to the gap below the storage box, and then flow into the lower space through the ventilation hole, and then be discharged from the exhaust port, thereby achieving heat dissipation of the heat generated by the air pump in the air pump device.

[0014] In summary, the component design improvements in the above technical solutions can effectively solve the problems that during the use of the existing atomizer, the internal air pump will generate loud noise when it is started, and this noise may affect the user's rest, and the air pump will generate heat during operation, and if this heat cannot be effectively discharged to the outside, it may cause damage to the internal electrical components. The partition is used to separate the interior of the atomizer shell into two upper and lower spaces, which is equivalent to sealing the air pump in the air pump device in the lower space to a certain extent. Only the ventilation holes of the partition can transmit the sound of the air pump, but a storage box is set on the partition so that the ventilation holes will not be directly exposed to the outside, thereby reducing the noise generated by the air pump to a certain extent.

[0027] This application proposes a noise reduction structure for an air pump device, see the attached Figures 1 to 5 As shown, a noise reduction structure of an air pump device includes an atomizer shell 1, the top of the atomizer shell 1 is rotatably connected to the atomizer shell flip cover 2, a partition 5 is arranged inside the atomizer shell 1, the partition divides the internal space of the atomizer shell 1 into an upper accommodating space and a lower accommodating space, a ventilation hole 6 is opened on the surface of the partition 5, and the atomizer shell 1 is provided with air inlets 4 on the outer walls on both sides of the upper accommodating space.

[0028] A housing base 8 is also provided at the bottom of the atomizer housing 1, and an air pump device 9 is installed in the lower accommodating space. The air pump device 9 is arranged on the housing base 8, a fan 11 is provided at the bottom of the air pump device 9, and an exhaust port 12 is provided on one side of the fan 11.

[0029] A storage box 3 is further provided in the upper accommodation space. The storage box 3 is detachably mounted in the upper accommodation space, and the bottom and side of the storage box 3 respectively form gaps with the partition 5 and the inner side of the accommodation space on the atomizer housing 1 for heat dissipation airflow to flow.

[0030] A limiting block 7 is disposed inside the upper accommodating space, and a limiting groove 14 is disposed at the bottom of the storage box 3 . The storage box 3 is mounted in the upper accommodating space through the limiting groove 14 and the limiting block 7 .

[0031] It should be noted that the air pump device 9 is an important component of the nebulizer, and a household nebulizer includes an air pump, which is a very mature technology. The specific components are clearly recorded in a medical nebulizer with publication number CN218420595U, and are also clearly recorded in other existing related disclosed patents. Examples are not given one by one here. At the same time, the principle of the nebulizer and the component structure of the air pump device 9 can also be searched in relevant search engines, so no further details are given here; the power supply wiring of the air pump device 9 can be connected to the power supply unit 10 through the controller, and the charging interface 13 can charge the power supply unit 10 by connecting to the corresponding connector.

[0032] It should be noted that the partition 5 divides the interior of the atomizer housing 1 into two spaces, upper and lower, which is equivalent to sealing the air pump in the air pump device 9 in the lower space to a certain extent, and only the ventilation hole 6 of the partition 5 can transmit the sound of the air pump. However, a storage box 3 is arranged on the partition 5 so that the ventilation hole 6 is not directly exposed to the outside, thereby blocking the sound transmitted from the ventilation hole 6 to a certain extent, thereby reducing the noise emitted by the air pump to a certain extent;

[0033] It is worth noting that an air inlet 4 is opened in the upper space through the atomizer shell 1, and a fan 11 is provided at the bottom of the air pump device 9 in the lower space.

Only the ventilation holes 6 of the partition 5 can transmit the sound of the air pump, but a storage box 3 is arranged on the partition 5 so that the ventilation holes 6 will not be directly exposed to the outside, thereby blocking the sound transmitted from the ventilation holes 6 to a certain extent, and reducing the noise generated by the air pump to a certain extent; 2. An air inlet 4 is opened in the upper space through the atomizer housing 1, and a fan 11 is arranged at the bottom of the air pump device 9 in the lower space. When the fan 11 is running, the air flow will flow in from the air inlet 4 in the upper space, flow through the gap of the side wall, and then flow to the gap below the storage box 3, and then flow into the lower space through the ventilation holes 6, and then be discharged from the exhaust port 12, thereby realizing the heat dissipation of the heat generated by the air pump in the air pump device 9.
