Pressure storage type spray pump and pressure storage type spray device

A pressure storage type spray pump (P1, P2, P3), comprising a main column (4) and a cylinder body (3), wherein a fluid channel (41) extending in an axial direction is formed inside the main column (4), and the cylinder body (3) accommodates a working liquid and is inserted with the main column (4);

• the spray pump further comprises a one-way valve mechanism, a storage chamber (M), and an upper elastic mechanism which are axially arranged between the main column (4) and the cylinder body (3);
• the storage chamber (M) is formed between the one-way valve mechanism and the upper elastic mechanism;
• the one-way valve mechanism is configured to be opened only when the main column (4) is pressed and only allow the working liquid to flow from the cylinder body (3) into the storage chamber (M);
• the upper elastic mechanism is configured to be capable of displacing, relative to the main column (4), between an initial position and a maximum compression position;
• the upper elastic mechanism displaces towards the maximum compression position when the main column (4) is pressed, so that the storage chamber (M) is in fluid communication with the fluid channel (41);
• and the upper elastic mechanism displaces towards the initial position when the main column (4) is released.
