[0030] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.

[0031] The drawings will be described below in connection with the drawings in the embodiments of the utility model Figures 1-5 The application will be further described in detail,

[0032] The embodiment of the application discloses a variable single-double air duct device of a sterilization machine, which comprises a connecting support 1, a fixed gasket 4 and a wind wheel 7. The connecting support 1 is a hollow structure and is connected with a wind drum A 2 and a wind drum B 3 at two ends respectively. The fixed gasket 4 is located on one side of the wind drum A 2 and is used for mounting and fixing the motor 5. The wind wheel 7 is provided with two wind wheels and is located in the wind drum A 2 and the wind drum B 3 respectively. The double-end output shaft on the motor 5 is fixedly connected with the gear 6 fixed in the center of the two wind wheels 7 after penetrating through the connecting support 1 and the fixed gasket 4.

[0033] The wind drum A 2 and the wind drum B 3 are connected through the connecting support 1. The motor 5 is fixed on the connecting support 1 on one side of the wind drum A 2. The connecting support 1 is a hollow structure and is connected with the wind drum A 2 and the wind drum B 3 at two ends respectively, which provides a physical basis for the switching of the single-double air duct. The double-end output shaft on the motor 5 is fixedly connected with the gear 6 in the two wind wheels 7 after penetrating through the connecting support 1 and the fixed gasket 4, which means that the motor 5 can drive the two wind wheels 7 to work at the same time. When the wind wheel 7 works, the airflow driven by the rotation of the wind wheel 7 can directly heat the motor 5 through the hollow structure of the connecting support.

[0034] In the case that the single air duct structure is unchanged, the switching of the single-motor single air duct to the single-motor double air duct is realized by increasing the connecting support and the wind drum.

[0035] The connecting support 1 comprises a fixed ring 102 provided with a hollow hole 101 and a plurality of quadrilateral connecting rods B 103 arranged equidistantly around the circumferential direction of the fixed ring 102 and located on both sides of the fixed ring 102.

[0036] The connecting support 1 is designed as a hollow support. When the motor 5 drives the two wind wheels 7 to rotate, the airflow is simultaneously driven to heat the motor 5. The airflow provides heat dissipation for the motor 5. In this way, the heat dissipation efficiency of the motor 5 is improved, the service life of the motor 5 is prolonged, and the demand for external heat dissipation facilities is reduced.

[0037] The hollow support and the equidistant arrangement of the quadrilateral connecting rods make the installation of the wind drum A2 and the wind drum B3 more convenient and fast, improve the concentricity, reduce the installation error, and ensure the stability and operation efficiency of the whole device.

[0038] The wind drum A2 and the wind drum B3 are both formed by the butt joint of the inner air duct 201 and the outer air duct 202. The outer side of the butt joint of the inner air duct 201 and the outer air duct 202 is provided with a hole mounting column 203. The inner air duct 201 and the outer air duct 202 are fixed together by the bolts penetrating the hole mounting column 203 on the inner air duct 201 and the outer air duct 202.

[0039] The quadrilateral connecting rod 103 is provided with a mounting hole 104 for the through fixed ring 102. The wind drum A2, the wind drum B3 and the fixed ring 102 are screwed together by the bolts penetrating the inner air duct 201 of the wind drum A2 and the wind drum B3 and the mounting hole 104.

[0040] The wind drum A2 and the wind drum B3 are fixed together with the connecting support 1 to form an air duct assembly for the sterilization machine. The assembly and assembly are convenient. The wind drum A2 and the wind drum B3 are assembled into an integrated structure with the connecting support 1, which reduces the complexity of assembly.

[0041] The wind drum A2 and the wind drum B3 are butt jointed by the inner air duct 201 and the outer air duct 202, and are screwed together by the connecting support 1 and the fixed ring 102, forming an integrated air duct assembly. This not only simplifies the assembly process of the assembly, but also improves the structural strength and airflow performance of the whole device.

[0042] The fixed gasket 4 is provided with a quadrilateral connecting rod A8 at four corners. The fixed gasket 4 is fixed on the inner air duct 201 of the wind drum A2 by the bolts penetrating the fixed gasket 4 and the quadrilateral connecting rod A8. The fixed gasket 4 is installed on the wind drum A2 and located on one side of the motor 5 and used for fixing the motor 5. The fixed gasket 4 is provided with a quadrilateral connecting rod A8 at four corners. This design not only facilitates the installation of the fixed gasket 4, but also reduces material consumption while not affecting the fixing performance of the motor 5, thereby reducing the cost.

[0043] The wind drum A2 and the wind drum B3 are both provided with a horn type air outlet 204. The horn type air outlet 204 can increase the air flow and improve the stability of the air outlet. This design helps to provide uniform airflow distribution during the sterilization process, ensuring the consistency and reliability of the sterilization effect

[0044] As Figure 5As shown, both the wind drum A2 and the wind drum B3 are provided with eight mounting feet 205. This helps to simplify the installation process of the wind drum. The mounting feet 205 can provide stable support, making the wind drum more stable during installation and operation, reducing vibration and noise, and improving the overall user experience. The arrangement of eight mounting feet 205 is suitable for different installation needs and has good installation flexibility.

[0045] The wind blades 701 on the wind wheel 7 are arranged in left and right intervals around the circumferential direction of the wind wheel 7. This helps to better drive the airflow. The interval arrangement of the wind blades 701 can reduce the mutual interference between the wind blades 701, providing more stable and orderly airflow, thereby improving the efficiency and stability of the airflow.

[0046] The sterilization machine can change the single or double air duct device. Through the design of the variable single or double air duct, the user can choose the single or double air duct working structure according to the actual sterilization needs. The single air duct structure may be suitable for specific sterilization occasions, while the double air duct structure can provide higher efficiency when more air flow is needed. The double air duct design can provide more air flow, which may speed up the sterilization process and improve the sterilization effect. At the same time, the double air duct can also provide better temperature distribution and circulation to ensure uniform sterilization.

[0047] The hollow connection bracket 1 design can reduce the overall volume of the equipment, save space, and is especially suitable for sterilization environments with limited space. The fixing gasket 4 is located on one side of the wind drum A, which facilitates the installation and maintenance of the motor 5. At the same time, the wind wheel 7 is located inside the wind drum, which also facilitates the inspection and cleaning of the wind wheel 7.

[0048] The hollow structure of the connection bracket 1 and the installation method of the fixing gasket 4 can provide stable support to ensure the stable operation of the motor 5 and the wind wheel 7, reducing vibration and noise. The double-end output shaft design on the motor 5 can be fixedly connected with the central gear 6 inside the wind wheel 7, improving the concentricity.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features. Any modification, equivalent substitution, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
