Problems solved by technology

[0003] The air pump usually includes a one-way valve, which ensures the stability of the airflow direction of the air pump. However, in the related art, when the one-way valve of the airflow control component airflow control component is opened and closed, the installation plate will be flapped, resulting in the working noise of the air pump. Larger, and will affect the service life of the check valve, thereby reducing the service life of the air pump

Embodiment 1

[0055] In order to solve the problems in the prior art that the air pump is noisy and the service life of the one-way valve in the air pump is short, as Figure 1-Figure 3 As shown, this embodiment discloses an airflow control assembly 1, wherein the airflow control assembly 1 can be used in an air pump, or in other pneumatic systems, as a gas flow direction limiting device in the pneumatic system. Specifically, the airflow control assembly 1 includes: an end cover 10 , a connecting plate 20 and a one-way valve 30 .

[0056] Wherein, a first air port 110 is opened on the end cover 10 . Specifically, combined with figure 1 and Figure 4 As shown, in a feasible implementation, the first air port 110 and the end cover 10 are formed in such a way that the end cover 10 extends toward the side away from the one-way valve 30 to form an extension end 120 , and at the extension end The first air port 110 is formed on the part 120, so that when the one-way valve 30 is opened, the air...

Embodiment 2

[0093] refer to Figure 4-Figure 6 As shown, this embodiment provides an air pump 2 , including: an air pump body 21 and an airflow control assembly 1 . The airflow control assembly 1 is arranged on the air pump body 21 , and an air chamber 27 is formed on the air pump body 21 .

[0094] Wherein, the airflow control assembly 1 in this embodiment has the same structure as the airflow control assembly 1 provided in the first embodiment, and can bring about the same or similar technical effects, and will not be described here one by one. For details, please refer to the first embodiment description of.

[0095]In this embodiment, when the ventilation end 310 of the one-way valve 30 is opened, the air cavity 27 of the air pump body 21 communicates with the second air port 210 and the first air port 110 to form an air flow channel. Since in this embodiment, the one-way valve 30 is installed on the second air port 210 of the connecting plate 20, and the open end 320 communicates w...

Abstract

The invention provides an airflow control assembly and an air pump. The airflow control assembly comprises an end cover, a connecting plate and a one-way valve, wherein the end cover is provided with a first air opening, the connecting plate is provided with a second air opening, and the one-way valve is provided with a ventilation end capable of being opened in one direction under the action of airflow. During use, the ventilation end can be opened or closed under the action of airflow, and when ventilation is needed, the ventilation end is opened, so that the first air opening and the second air opening communicate with an air cavity of the air pump. Due to the fact that the one-way valve is an elastic one-way valve, in the opening and closing process of the ventilation end, the elastic one-way valve has a good vibration absorption effect, meanwhile, the ventilation end is not in contact with the end cover and the connecting plate, so that the phenomenon that the ventilation end beats the end cover or the connecting plate in the opening and closing process can be avoided, therefore, noise generated when the air pump works is effectively reduced, in addition, the one-way valve is protected to a certain degree, and therefore, the service lives of the one-way valve and the airflow control assembly are prolonged.

Description

technical field [0001] The invention relates to the technical field of air pumps, in particular to an air flow control assembly and an air pump. Background technique [0002] An air pump refers to a device that removes air from a closed space or adds air from a closed space. [0003] The air pump usually includes a one-way valve, which ensures the stability of the airflow direction of the air pump. However, in the related art, when the one-way valve of the airflow control component airflow control component is opened and closed, the installation plate will be flapped, resulting in the working noise of the air pump. Larger, and will affect the service life of the check valve, thereby reducing the service life of the air pump. Contents of the invention [0004] The embodiment of the present application discloses an airflow control assembly and an air pump, which can reduce the noise of the air pump during operation and increase the service life of the one-way valve. [000...
