Therefore, when the airflow flows through the tapered section, the airflow flows from a position with a larger flow passage to a position with a smaller flow passage in the flow direction, so that the airflow is accelerated, and the airflow flowing from the air inlet end 3211 is low-speed air, while the airflow flowing from the air outlet end 3212 is high-speed air, thereby achieving the purpose of accelerating the airflow and further improving the cleaning effect of the airflow cleaning structure 32.

Further, referring to fig. 3, the air flow passage 321 includes: the lens comprises a first section 3213, a second section 3214 and a third section 3215, wherein the second section 3214 is connected between the first section 3213 and the third section 3215, the first section 3213 is connected to the gas inlet 3211, the third section 3215 is connected to the gas outlet 3212, and the gas outlet 3212 is adapted to spray cleaning gas to the first lens 311. Specifically, the external low-speed gas flows into the first section 3213, the second section 3214 and the third section 3215 from the gas inlet 3211, and finally flows out from the gas outlet 3211 to form high-speed gas, and is sprayed toward the first lens 311, so as to clean the first lens 311.

The air inlet end 3211 is formed on an outer sidewall of the dust-proof structure 31 so as to communicate with an external air transmission pipeline, and the air outlet end 3212 is disposed near the first lens 311 so as to spray high-speed air to the first lens 311.

As shown in fig. 3, the first segment 3213 has a greater flow cross-section than the second segment 3214. Because the first segment 3213 is closer to the inlet end 3211, the low-speed gas flows from the inlet end 3211, then flows through the first segment 3213 and then flows through the second segment 3214, and because the flow cross-section of the first segment 3213 is greater than that of the second segment 3214, the gas flow is accelerated after flowing from the first segment 3213 into the second segment 3214, so as to accelerate the gas flow of the gas flow cleaning structure 32.

With reference to the embodiments shown in fig. 1 to 3, the dust-proof structure 31 includes: base 312 and first lens 311, first lens 311 sets up on base 312, and camera lens 11 sets up in base 312 to keep apart with the external world in order to avoid being infected with the foreign matter on the second lens 111, wherein, first section 3213 and second section 3214 form in base 312, in order to increase the length of airflow channel 321, make low-speed gas have longer route and accelerate, in order to realize better acceleration effect.

further, referring to fig. 5, in combination with fig. 1 to 3, the dust-proof cleaning apparatus 3 further includes: the flow guide block 322, the flow guide block 322 is disposed on the dust-proof structure 31, and the flow guide block 322 is suitable for pressing and fixing the first lens 311 on the base 312, so as to ensure the stability of the first lens 311. Wherein the third segment 3215 is formed on the deflector block 322. Since the flow guide block 322 is closer to the first lens 311, the third segment 3215 and the gas outlet end 3212 are disposed on the flow guide block 322.

As shown in fig. 1 to 4, an annular sealing film 4 is sandwiched between the flow guide block 322 and the first lens 311, and the sealing film 4 can perform a good sealing function, so as to prevent the gas ejected from the gas outlet end 3212 from flowing out of the camera module 100 from a gap between the flow guide block 322 and the first lens 311, thereby ensuring a cleaning effect.

That is, the inclined segment 32152 has a smaller space than the straight segment 32151, so that the cleaning gas is compressed to cooperate with the gas guide opening 41 to accelerate the cleaning gas for the second time, thereby improving the acceleration effect.

With reference to the embodiment shown in fig. 2, 3 and 6, the first lens 311 has a lens through hole 3111 corresponding to the second segment 3214, and the second segment 3214 is adapted to communicate with the third segment 3215 through the lens through hole 3111. Because the first lens 311 is disposed between the flow guiding block 322 and the base 312, the second segment 3214 can be communicated with the third segment 3215 by disposing the lens through hole 3111 on the first lens 311, so as to ensure that the airflow channel 321 is smooth.

In a preferred embodiment, the width of the air guide opening 41 increases from the outer end to the inner end (not shown). That is, the air guide opening 41 is formed as a flared opening with a narrow inner end and a wide open end to form an air guide structure, so that the cleaning air entering into the air guide opening 41 from the air outlet end 3212 can be blown over the first lens 311 by the guiding action of the air guide opening 41 to achieve a thorough cleaning effect.

Referring to fig. 5, in combination with fig. 1-3, the diversion block 322 has a peripheral wall 3221 and a stopping wall 3222 extending radially inward from one end of the peripheral wall 3221, the peripheral wall 3221 is adapted to fit over a boss formed at the front end of the base 312 to stably fix the diversion block 322 on the base 312, and the stopping wall 3222 is adapted to press the first lens 311 to stably fix the first lens 311 on the base 312.
