The driving component is used to drive the control component to move up and down along the length direction of the sleeve. The sleeve is used to drive the moving path of the control component. The connecting seat is connected to the mounting frame. The control component controls the air suction port to suck air when moving up. When the control component moves down, the air inflation port conveys gas outwards for inflation. The air suction valve plate is used to seal the air suction port during inflation. The matching component is used to seal the air inflation port during suction, which can meet the inflation and suction requirements.

[0007] Preferably, the driving component includes a motor arranged on the mounting frame, a first gear arranged at the output end of the motor, and a second gear arranged on the mounting frame and meshing with the first gear.

[0030] The following will further describe the present application in detail with reference to the attached Figures 1-5 drawings.

[0031] An embodiment of the present application discloses a combined suction and inflation pump head. Referring to Figure 1 , Figure 2 and Figure 3 , it includes a mounting bracket 1, a sleeve 4 mounted on the mounting bracket 1, a connecting seat 5 mounted on the mounting bracket 1 and located below the sleeve 4, a control assembly 3 disposed in the sleeve 4, and a driving assembly 2 disposed on the mounting bracket 1 and used to drive the control assembly 3 to move up and down in the sleeve 4. An air suction port 6 communicating with the sleeve 4 is formed on the connecting seat 5, an air inflation port 8 communicating with the sleeve 4 is formed on the connecting seat 5, an air suction valve plate 7 is mounted on the connecting seat 5 at the air outlet end of the air suction port 6, a mounting hole 15 communicating with the air inflation port 8 is formed on the connecting seat 5, and a matching assembly 9 for controlling the opening and closing of the air inlet end of the air inflation port 8 is provided in the mounting hole 15. When the driving assembly 2 drives the control assembly 3 to move upward, the control assembly 3 drives the air suction valve plate 7 to move upward for sucking air through the air suction port 6; in the embodiment of the present application, an air suction pipe 24 is installed at the air suction port 6, and an air suction nozzle 25 is installed at one end of the air suction pipe 24 away from the air suction port 6, facilitating the air suction operation. When the driving assembly 2 drives the control assembly 3 to move downward, the control assembly 3 moves downward to press down the gas in the sleeve 4 and the matching assembly 9 moves downward, facilitating the discharge of the gas from the air inflation port 8 for inflating the air inflation port 8.

[0032] Referring to Figure 2 and Figure 3 , in order to improve the sealing performance between the connecting seat 5 and the mounting bracket 1, an embedding ring 19 is fixed along the circumferential direction of the sleeve 4 on the side of the mounting bracket 1 facing the connecting seat 5, and an embedding groove 20 for the embedding ring 19 to be embedded is formed on the connecting seat 5. A fixing member 18 is installed on the connecting seat 5 and the mounting bracket 1. In the present application, the fixing member 18 uses a bolt, and the bolt fixes the connecting seat 5 and the mounting bracket 1 together, improving the connection stability between the connecting bracket and the fixing seat and the embedding tightness of the embedding ring 19 in the embedding groove 20.

[0033] Referring to Figure 2 and Figure 3, the driving component 2 includes a motor 21 fixedly installed on the mounting frame 1, a first gear 22 fixedly installed at the output end of the motor 21, and a second gear 23 installed on the mounting frame 1 and meshing with the first gear 22. To reduce the friction between the mounting frame 1 and the second gear 23, a bearing 10 located at the connection between the mounting frame 1 and the second gear 23 is fixedly installed on the mounting frame 1. To extend the service life of the motor 21, a cooling fan 17 for cooling the motor 21 is installed on the motor 21. The control component 3 includes a connecting rod 31, a piston seat 32 fixedly installed at the end of the connecting rod 31 and located inside the sleeve 4, and a piston ring 33 sleeved on the piston seat 32. One end of the connecting rod 31 away from the piston seat 32 is installed with a rotating shaft 11 connected to the second gear 23, which facilitates the rotation of the second gear 23 to drive the connecting rod 31 to move up and down. The rotation of the motor 21 drives the rotation of the first gear 22, the rotation of the first gear 22 drives the rotation of the second gear 23, and the rotation of the second gear 23 drives the end of the connecting rod 31 to rotate and move up or down. The rotating shaft 11 facilitates the rotational connection between the end of the connecting rod 31 and the second gear 23, and facilitates the connecting rod 31 to drive the piston seat 32 to move up or down.

[0034] Referring to Figure 3 , since the lower end of the connecting rod 31 of the present application is fixedly connected to the piston seat 32, the connecting rod 31 will tilt as the second gear 23 rotates. At this time, the piston seat 32 will tilt synchronously. The piston ring 33 is made of an elastic material, and the piston ring 33 will seal the gap between the piston seat 32 and the sleeve 4. Ensure the sealing performance when the piston seat 32 moves. To improve the stability of the piston ring 33 on the piston seat 32, the piston seat 32 is provided with a groove in the circumferential direction for the piston ring 33 to be embedded. To improve the sealing performance between the piston seat 32 in an inclined state and the sleeve 4 by the piston ring 33, the piston ring 33 is trapezoidal, and a deformation extrusion groove is circumferentially opened along the length direction of the bottom surface of the piston ring 33 to improve the extrusion sealing effect of the piston ring 33. The connecting rod 31 of the present application is rigidly connected to the end of the piston seat 32, mainly to improve the movement stability and structural stability of the control component 3 and improve the service life of the structure.

[0035] Referring to Figure 4 and Figure 5 , to improve the stability of the intake valve sheet 7 on the connection seat 5, a positioning hole 12 is opened at one end of the intake valve sheet 7 away from the intake port 6. A positioning block 13 inserted into the positioning hole 12 is fixedly installed on the connection seat 5, and a positioning piece 14 for positioning the intake valve sheet 7 is sleeved on the positioning block 13 to further improve the stability of the intake valve sheet 7 on the connection seat 5. When the connecting rod 31 drives the piston seat 32 to move up, the upward movement drives the unfixed end of the intake valve sheet 7 to move up, and the intake valve sheet 7 moves up to expose the outlet end of the intake port 6, facilitating the intake operation.

[0036] Referring to Figure 3 and Figure 5, the cooperating component 9 is used to control the inflation port 8 to perform an inflation operation. The cooperating component 9 includes a fixed plug 91 located at the air outlet end of the mounting hole 15, an exhaust spring 92 fixed within the fixed plug 91 and located within the mounting hole 15, and an exhaust gasket 93 fixedly mounted on the exhaust spring 92 and used to seal the air inlet end of the mounting hole 15. When the piston seat 32 moves downward, the piston seat 32 presses down the gas within the sleeve 4. The exhaust gasket 93 is pressed downward under pressure to squeeze the exhaust spring 92. After the exhaust gasket 93 moves downward, the air inlet of the inflation port 8 is exposed, facilitating the inflation operation of the inflation port 8. To improve the sealing effect of the fixed plug 91, a sealing ring 16 is sleeved on the fixed plug 91 at the connection between the fixed plug 91 and the connecting seat 5, and the sealing ring 16 further improves the sealing effect of the fixed plug 91.

[0037] The implementation principle of an integrated inflating and sucking pump head according to an embodiment of the present application is as follows: When the motor 21 starts, it drives the connecting rod 31 to move up and down. When the connecting rod 31 moves upward, it sucks air, and when it moves downward, it inflates, playing the role of integrating air suction and inflation, effectively reducing the installation space of the pump head and improving the practicality of the pump head.

[0038] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
