Problems solved by technology

However, during the assembly and pressing process of this valve plate, each blade 1' is easily deformed due to extrusion, and the deformed blades 1' will appear arched, which causes the blades 1' to be in the reset state. The corresponding air outlet cannot be effectively blocked, resulting in poor airtightness of the air pump, and the quality cannot be guaranteed

Embodiment 1

[0025] See figure 2 As shown, a valve plate with improved airtightness of the present invention, the valve plate 1 has three elastically swingable blades 11, three ribs 12 arranged in the radial direction, and a valve plate located at the top of the middle part of the valve plate 1. The mounting column 13 on the surface; the three blades 11 of the valve plate 1 are distributed along the circumferential direction, and are generally similar to a circular structure, and every two adjacent blades 11 are separated by ribs 12; the roots of each blade 11 are respectively connected to the installation The columns 13 are integrally connected. Each blade 11 is provided with a buffer structure at the outer end for connecting with the rib 12 . Here, the buffer structure is a relief gap 14 for providing a deformation buffer space for the assembly and extrusion of each blade 11 .

[0026] The mounting column 13 of the above-mentioned valve plate 1 is in a similar triangular structure, and...

Embodiment 2

[0035] See Figure 5 As shown, a valve plate with improved airtightness of the present invention differs from Embodiment 1 in that: the buffer structure of the valve plate 1 is a film 15, and the film 15 is connected to the circumferential direction of each vane 11 of the valve plate 1. Between the two ends of and the corresponding ribs 12.

[0036] A valve plate with improved airtightness of the present invention adopts the film 15 as a buffer structure. In addition to the above-mentioned advantages, that is, providing a buffer space for the blades 11 to assemble and squeeze deformation, it also has another advantage: it can strengthen each blade. 11 strength, improve the performance of the air pump.

[0037] The valve plate described in the second embodiment can also be applied to an air pump.

Abstract

The invention discloses a valve block with improved air tightness and an air pump, wherein the valve block is provided with at least two elastically swinging blades, the blades are separated by radially arranged ribs, and a buffering structure is arranged at the end part, used for connecting the rib, of each blade to provide a deformation buffering space for the assembly and extrusion of each blade. The air pump is provided with the valve block with improved air tightness, and each blade of the valve block, as a one-way air outlet valve block of the air pump, is matched in the air pump. The structure of the valve block is improved to effectively prevent each blade in the valve block from deforming or bulging during the assembly, so that the air tightness of the air pump is greatly improved.

Description

technical field [0001] The invention relates to the field of air pumps, in particular to a valve plate with improved air tightness and an air pump. Background technique [0002] At present, the air pump of the prior art usually adopts such as attached figure 1 The valve plate shown is used as an air outlet one-way valve plate. The valve plate has a circular structure as a whole. It has three elastically swingable blades 1', and the three blades 1' are composed of three radially arranged ribs 2'. Separated, the two ends of each blade 1' along the circumferential direction are integrally connected with the ribs 2' respectively. In the air pump, this kind of valve slice uses the elastic swing up and down of each vane 1' to open or block the corresponding air outlet hole to form a one-way air outlet flow distribution. However, during the assembly and pressing process of this valve plate, each blade 1' is easily deformed due to extrusion, and the deformed blades 1' will appear ...
