[0018] The following will be combined with the drawings in the embodiments of the present disclosure / the present application to clearly and completely describe the technical solutions in the embodiments of the present disclosure / the present application. Obviously, the described embodiments are only part of the embodiments of the present disclosure / the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure / the present application and its application or use. Embodiment 1

[0019] The present embodiment provides a multifunctional blowing head for a precision filter element of an air compressor, so as to solve the problem in the prior art that the precision filter element 8 is not cleaned thoroughly enough, resulting in poor regeneration and reusability of the precision filter element 8 .

[0020] refer to Figure 1 and Figure 2 The multifunctional blowing head of the air compressor precision filter provided in this embodiment includes a ventilation handle 1, which can be optionally made into a long cylindrical shape that is easy to grasp, and an air inlet channel 1.1 is provided in the ventilation handle 1. The air inlet 7 of the air inlet channel 1.1 is used to communicate with the air source device, for example, the air inlet 7 can be connected to the air pipe. At the other end opposite to the air inlet 7, the air inlet channel 1.1 also includes a first outlet 1.2 and a second outlet 1.3, the first outlet 1.2 and the second outlet 1.3 are arranged in parallel, the first outlet 1.2 is connected to the diffuser guide pipe 2, the diffuser guide pipe 2 has a plurality of diffuser holes 10, the shape of the diffuser guide pipe 2 matches the inner diameter of the precision filter element 8, and the second outlet 1.3 is connected to the nozzle 3. For example, when the interior of the precision filter element 8 is cylindrical, the diffuser guide tube 2 can also be cylindrical, and the outer diameter of the diffuser guide tube 2 is smaller than the inner diameter of the precision filter element 8; or when the internal cross-section of the precision filter element 8 is a special shape, the cross-section of the diffuser guide tube 2 can also be set to a matching shape for easy insertion into the interior of the precision filter element 8, and the diffuser guide tube 2 can also be set to a cylindrical shape that is smaller than the minimum internal diameter of the precision filter element 8, so as to facilitate rotation and cleaning inside the precision filter element 8. Considering that the interior of the precision filter element 8 is more delicate than the external structure, the interior of the precision filter element 8 generally uses non-metallic materials that are more easily damaged. The internal structure of the precision filter element 8 can be better improved through diffuser cleaning.

[0021] Optionally, in other non-limiting embodiments of the present application, considering that the diffuser guide pipe 2 needs to be cleaned inside the precision filter element 8, in order to prevent conflict with the nozzle 3, the nozzle 3 can be configured to be detachably connected to the second outlet 1.3, or the nozzle 3 is close to the outer wall of the diffuser guide pipe 2 and the radius of the nozzle 3 is reduced, or when the air flow velocity loss is within an acceptable range, Figure 1 and Figure 2 Contrary to the illustration, the nozzle 3 and the precision filter element 8 are arranged in different directions, but in a bifurcated arrangement, so that their positions will not interfere with each other during use.

[0022] The ventilation handle 1 is provided with an airflow distribution device for controlling the opening and closing of the first outlet 1.2 and the second outlet 1.3. For the cleaning of the inside and outside of the precision filter 8, the first outlet 1.2 or the second outlet 1.3 is selectively opened. Optionally, the airflow distribution device can adopt a common diverter plate, diverter tube or diverter on the market. For example, a diverter plate: a simple airflow diverter device, which allows the airflow to be dispersed into multiple small parts through these small holes by opening a plurality of small holes on it. The design of the diverter plate can be adjusted according to specific needs, such as adjusting the size and number of small holes to control the distribution of the airflow; a diverter tube: a pipeline-type airflow diverter device, which allows the airflow to be divided into multiple small parts after entering the main pipeline by setting a plurality of branch pipes inside it, and enters each branch pipe respectively. The design of the diverter tube can be adjusted according to specific needs, such as changing the number and length of branch pipes to control the distribution of the airflow; a diverter: a more complex airflow diverter device, usually composed of multiple components, including an air inlet, a diverter body and multiple air outlets. An airflow guide device is provided inside the diverter, and the direction and intensity of the airflow can be adjusted as needed to achieve more precise control. Flow splitters are often used in applications where highly precise control of airflow is required.

[0023] When in use, connect the air inlet 7 to the air pipe of the air source equipment, hold the ventilation handle 1, and refer to Figure 1 or Figure 2 , open the second outlet 1.3 and close the first outlet 1.2, use the nozzle 3 to clean the outer surface of the precision filter element 8; close the second outlet 1.3 and open the first outlet 1.2, insert the diffuser guide tube 2 into the interior of the precision filter element 8, and gently clean the precision filter element 8 from the inside to improve the regeneration reusability of the precision filter element 8. The diffuser guide tube 2 can also be rotated and moved up, down, left and right for sufficient spray cleaning.

[0024] Compared with traditional cleaning tools, the multifunctional spray head for the air compressor precision filter element provided in this embodiment can clean the inside and outside of the precision filter element 8 more comprehensively, gently and protectively, improve the regeneration and reusability of the precision filter element 8, and reduce the use cost of the precision filter element 8.

This design enables the airflow to better contact the target object and improves the spraying effect. In some application scenarios, the beveled nozzle can also help achieve a more uniform spray distribution, thereby improving work efficiency; compared with the traditional straight nozzle, the beveled nozzle can better control the diffusion and loss of the airflow. By adjusting the inclination angle and size of the nozzle, the resistance of the airflow during the spraying process can be reduced, thereby reducing the loss of the airflow. This can not only improve the spraying efficiency, but also reduce energy consumption. Reference Figure 1 When in use, the inclined surface of the beveled nozzle 9 is nearly parallel to the outer surface of the precision filter element 8.

[0027] In order to reduce the influence of the position of the nozzle 3 on the diffuser guide pipe 2, optionally, in a further preferred but non-limiting embodiment of the present application, refer to Figure 1 and Figure 2 The nozzle 3 is inserted into the diffusion guide pipe 2, and one end of the nozzle 3 with a beveled nozzle 9 passes through the end of the diffusion guide pipe 2, and the diffusion holes 10 are evenly distributed on the outer wall of the diffusion guide pipe 2 at all angles.

Optionally, in a further preferred but non-limiting embodiment of the present application, the inner diameter from the air inlet 7 to the first outlet 1.2 and the second outlet 1.3 gradually decreases; for example, in this embodiment, the inner diameter decreases from the air inlet 7 to the inside of the air inlet channel 1.1, and from the inside of the air inlet channel 1.1 to the location of the first ball valve 4 and the second ball valve 5, thereby increasing the outlet velocity of the airflow and improving the purging efficiency.
