DETAILED DESCRIPTION

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings, which are intended to explain the present invention rather than to limit it.

[0028] See also Figure 1-7 , an atomizer air inlet adjustment structure, comprising an atomization cover 1, an adjustment cover 2, a first structure and a second structure;

[0029] The atomizing cover 1 is provided with an air inlet 3, and the adjusting cover 2 is provided with an airflow adjusting hole 9. The adjusting cover 2 is sleeved on the atomizing cover 1, and the air inlet 3 and the airflow adjusting hole 9 can be communicated. The first structure and the second structure are arranged between the atomizing cover 1 and the adjusting cover 2 of the atomizer, and abut against each other through friction resistance, so as to position the adjusting cover 2 in the rotation direction.

[0030] The first structure and the second structure are respectively arranged on the atomizing cover 1 and the adjusting cover 2. When the air intake of the atomizer is adjusted, the second structure rotates synchronously when the adjusting cover is rotated. When the adjusting cover stops rotating, the first structure and the second structure remain in position under the action of friction resistance.

[0031] In another embodiment, the arrangement positions of the first structure and the second structure may be interchanged, that is, the second structure is fixed on the atomizing cover 1 , and the first structure is arranged on the adjusting cover 2 .

[0032] The first structure is a boss structure, and the second structure is a groove structure matching the boss structure. The boss structure is located in the groove structure to achieve circumferential positioning of the atomizing cover 1 and the adjusting cover 2.

[0033] The boss structure is arranged on the self-adjusting cover 2, and the groove structure is arranged on the atomizing cover 1. The multiple groove structures are arranged at circumferential intervals. The boss structure is located in any groove structure. When the adjusting cover is rotated, the boss structure moves to the adjacent groove structure. The adjusting cover rotates the airflow adjusting hole and the air inlet to be circumferentially misaligned, thereby adjusting the opening of the air inlet to achieve control of the air intake volume. The airflow adjusting hole and the air inlet have the same size structure. When the airflow adjusting hole and the air inlet coincide with each other, the air intake volume reaches a maximum. When the airflow adjusting hole and the air inlet are completely misaligned, the adjusting cover covers the air inlet.

[0034] The first structure and the second structure are respectively arranged on the side walls of the atomizing cover 1 and the adjusting cover 2. The first structure is a plurality of lock grooves 6 arranged on the outer wall of the atomizing cover, and the plurality of lock grooves are arranged along the circumference of the outer wall of the atomizing cover 1. The second structure is a positioning bead 10 arranged on the inner wall of the adjusting cover. The positioning bead 10 is located in the lock groove. The positioning bead 10 cooperates with different lock grooves to control the opening of the air inlet.

[0035] The positioning bead is a hemisphere formed on the inner wall of the regulating cover, and the locking groove is a spherical groove matched with the hemisphere, and the depth of the spherical groove is less than the height of the hemisphere.

[0036] A circumferentially arranged platform 7 is provided on the outer wall of the atomizing cover, and a plurality of locking grooves are circumferentially spaced on the platform. Positioning surfaces are provided at both ends of the platform, and a central angle formed by the two positioning surfaces is greater than the central angle of the air inlet. A fixing seat 11 is formed on the inner wall of the adjusting cover, and a positioning bead is provided on the fixing seat, and the fixing seat is located on the positioning surface. When the adjusting cover is rotated, the fixing seat rotates along the platform, and at the same time, the positioning surfaces at both ends of the platform can position the fixing seat, that is, the rotation angle of the adjusting cover is positioned.

[0037] In yet another embodiment, the boss structure is a positioning tooth, and the groove structure is a continuous tooth groove.

[0038] The atomizing cover is also provided with an axial positioning structure for axially positioning the regulating cover.

[0039] The axial positioning structure includes a clamping block 5 and a limiting boss 8, which are arranged on the atomizing cover and located at the upper and lower ends of the adjusting cover. The clamping block 5 and the limiting boss 8 limit the axial direction of the adjusting cover to prevent its axial movement.

[0040] The clamping block is a plurality of bosses arranged on the atomizing cover, and the plurality of bosses are arranged on the upper part of the atomizing cover. The limiting boss is an annular boss arranged on the lower part of the atomizing cover. The lower end surface of the adjusting cover is supported on the annular boss. A certain gap of 0.3-0.5mm is retained between the lower end surface of the boss and the upper end surface of the adjusting cover to facilitate the rotation of the adjusting cover.

[0041] The upper end surface of the boss is an inclined surface, and the inclination direction is the same as the installation direction of the atomizing cover. Figure 2 and 3 The adjusting cover is installed downward from the upper end of the atomizing cover, that is, the inclined surface of the boss is inclined from top to bottom. It should be noted that the width of the boss (along the radial direction of the atomizing cover) is slightly larger than the radial gap between the adjusting cover and the atomizing cover. Assuming that the installation gap between the adjusting cover and the atomizing cover is 0.3mm, the width of the boss is 0.8mm. The adjusting cover is in a trumpet shape. The adjusting cover is installed from top to bottom. The material of the adjusting cover is plastic. Since the plastic has very good shaping properties, the upper end of the adjusting cover passes through the boss by means of forced installation deformation. At the same time, since the upper end surface of the boss is an inclined surface, the adjusting cover can be quickly installed.

[0042] Example 1

[0043] A nebulizer includes a medicine liquid cup 4 and a nebulizer air inlet adjustment structure, an atomizer cover 1 is detachably mounted on the mouth of the atomizer cup, an air flow tube 12 is arranged in the medicine liquid cup, the lower end of the air flow tube 12 is connected to the outside of the medicine liquid cup, the upper end of the air flow tube 12 extends upward, an atomizer disperser 14 is arranged on the air flow tube 12, and a baffle 13 is arranged at the upper end of the atomizer disperser 14.

[0044] The nebulizer main unit is connected to the lower end of the air flow tube 12 through a pipeline, and the medicine cup 4 is filled with medicine liquid. The compressed air flows out through the atomizing disperser and forms a negative pressure effect. Under the action of the negative pressure, the medicine liquid and the compressed air are mixed. After mixing, they are sprayed onto the baffle driven by the compressed air. Through the collision effect, the medicine liquid impacts the baffle and then becomes micro-particle droplets and forms mist particles in parallel. The mist particles and the external gas entering from the air inlet generate aerosol and are input through the mist delivery pipe at the upper end of the atomizing cover.

[0045] Rotate the adjustment cover according to the patient's condition to control the overlap between the air inlet and the airflow adjustment hole, and then adjust the size of the external airflow. When the air inlet and the airflow adjustment hole are completely overlapped, the airflow is adjusted to the maximum, and the external air and the mist droplets form an aerosol, which enters the mask through the mist delivery tube at the upper end of the atomization cover and is inhaled by the patient.

[0046] Example 2
