[0015] Furthermore, the device boasts a compact structure and strong functionality. The housing is fixed to the blow molding equipment, and the internal components, such as the fan and heating elements, are rationally arranged. The fan creates negative pressure to promote gas flow, ensuring continuous and stable operation of the purification and drying process. The overall device has a high degree of integration, occupies little space, and is highly adaptable, effectively improving the working efficiency and reliability of blow molding equipment, demonstrating significant practical value and economic benefits.

[0029] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0030] Example 1: Please refer to Figures 1 to 6 :

[0031] This utility model proposes an air purification and drying device for bottle blowing, comprising: a housing 1; the housing 1 is fixed on the bottle blowing equipment, an exhaust pipe 101 is welded to the right side of the housing 1, the exhaust pipe 101 is connected to the pipe of the bottle blowing air supply pump, a filter screen holder 2 is inserted into the housing 1, a filter screen 201 is fixed on the filter screen holder 2, and a filter box 3 is inserted into and fixed on the housing 1. During use, the gas enters from the left filter screen 201, then passes through the filter box 3, and finally exits from the exhaust pipe 101. The dual filtration of the filter screen 201 and the filter box 3 can improve the purification effect of the gas.

[0032] The top surface of the inner wall of the housing 1 is fixed with a base block 5. Two spring rods 501 are fixed on the right end of the base block 5. The extended ends of the two spring rods 501 are fixed on the cleaning brush 502. The cleaning brush 502 contacts the filter screen 201. When cleaning the filter screen 201, the filter screen seat 2 is pulled upward. At this time, the debris on the filter screen 201 will be swept off by the action of the cleaning brush 502. The swept debris falls into the housing 1, which is convenient for subsequent cleaning. Moreover, due to the setting of the spring rods 501, the cleaning brush 502 can be automatically fed even if it is worn.

[0033] Inside the housing 1, a fan 6 is fixed. The fan 6 is aligned with the exhaust pipe 101. The fan 6 is electrically connected to an external power supply and the power switch of the external device. During use, when the fan 6 is powered, a negative pressure is formed inside the housing 1. Under the action of the negative pressure, the gas enters from the left side of the housing 1 and is discharged through the exhaust pipe 101.

[0034] The housing 1 contains a base 4, which has a U-shaped structure. A heating tube 401 is fixed inside the base 4. The heating tube 401 is electrically connected to an external power supply and an external power switch. During use, when the power supply to the heating tube 401 is turned on, the heat emitted from the heating tube 401 can dry the air.

[0035] The filter box 3 is a rectangular box structure filled with filter cotton. The filter box 3 is a secondary drying structure for gas. During use, when gas passes through the filter box 3, it can achieve better filtration and purification.

[0036] Example 2, based on Example 1, such as Figures 1 to 6 As shown, activated carbon is added to the filter cotton inside filter box 3. During use, the activated carbon can better purify the air.

[0037] The working principle of this embodiment is as follows: When the fan 6 is powered, a negative pressure is formed inside the housing 1. Under the action of the negative pressure, the gas enters from the left side of the housing 1 and is discharged through the exhaust pipe 101. At the same time, the power supply of the heating tube 401 is turned on. When the gas passes through the filter screen 201, the gas can be filtered through the filter screen 201. When the gas passes through the filter box 3, it can be filtered and purified again through the filter cotton and activated carbon. When cleaning the filter screen 201, pull the filter screen seat 2 upward. At this time, the debris on the filter screen 201 will be swept off by the cleaning brush 502. The swept debris falls into the housing 1. Then, the debris and dust can be manually removed from the bottom surface of the inner wall of the housing 1.
