[0029] The present application provides an electric air pump movement, including a cylinder and a motor. The cylinder includes a cylinder body, a first air outlet and a second air outlet. An air outlet hole is arranged at the end of the cylinder body. One end of the first air outlet is used to connect to an air outlet pipe, and the other end is communicated with the air outlet hole of the cylinder body. The second air outlet is communicated with the side of the first air outlet. A conical one-way valve is arranged inside the first air outlet. An elastic part is arranged at the end of the one-way valve away from the cylinder body to make the one-way valve press against the air outlet hole. A piston that can move toward the air outlet is arranged inside the cylinder body. The piston is connected to the motor through a transmission structure, and the motor can drive the piston to reciprocate in the cylinder body.
[0030] Implementation example Figures 1 to 5As shown, an electric air pump movement includes a cylinder 1, a motor 2 is arranged at the lower end of the cylinder 1, and a cylinder bracket 1.4 extends from the lower end of the cylinder 1 toward the motor 2. The motor 2 is fixedly connected to a connector 3 at one end close to the cylinder 1, and is fixedly connected to the cylinder bracket 1.4 of the cylinder 1 through the connector 3, thereby realizing the fixed connection between the cylinder 1 and the motor 2. The cylinder 1 also includes a cylinder body 1.3, a first air outlet 1.1 and a second air outlet 1.2. The first air outlet 1.1 is arranged at the upper end of the cylinder body 1.3, and an air outlet hole 1.5 connected to the first air outlet 1.1 is arranged at the end of the cylinder body 1.3, and the other end of the first air outlet 1.1 is used to connect to the air outlet pipe. The second air outlet 1.2 is connected to the side of the first air outlet 1.1, and a pressure sensor 4 is fixedly arranged at the second air outlet 1.2. The pressure sensor 4 is tightly matched with the second air outlet 1.2 and is electrically connected to the control circuit board to realize the monitoring of the air pressure during inflation and prevent overcharging.
[0031] Furthermore, a piston 5.4 is provided inside the cylinder 1.3 and can move toward the air outlet 1.5. The piston 5.4 is connected to the motor 2 through a transmission structure, and the motor 2 can drive the piston 5.4 to reciprocate in the cylinder 1.3. The transmission structure includes a first transmission gear 5.1, a second transmission gear 5.2 and a connecting rod 5.3. An output end is extended from each of the upper and lower ends of the motor 2. The first transmission gear 5.1 is connected to the output end of the upper end of the motor 2 near the cylinder 1 and rotates synchronously. The second transmission gear 5.2 is rotatably arranged on the cylinder bracket 1.4. The rotating shaft of the first transmission gear 5.1 is arranged perpendicular to the rotating shaft of the second transmission gear 5.2, and the first transmission gear 5.1 and the second transmission gear 5.2 are meshed with each other. One end of the connecting rod 5.3 is connected to the piston 5.4, and the other end is rotatable and eccentrically arranged on the second transmission gear 5.2. A limiting gasket 5.5 is sleeved on the rotating shaft of the end of the connecting rod 5.3 that is matched with the second transmission gear 5.2. The limiting gasket 5.5 is arranged on the side of the rotating shaft away from the second transmission gear 5.2. In actual use, the limiting gasket 5.5 can effectively prevent the connecting rod 5.3 from falling off. When the motor 2 is started, its output end drives the first transmission gear 5.1 to rotate, and the first transmission gear 5.1 drives the second transmission gear 5.2 meshing with it to rotate. When the second transmission gear 5.2 rotates, the connecting rod 5.3 eccentrically connected thereto will drive the piston 5.4 to reciprocate inside the cylinder body 1.3 to achieve the inflation operation.
[0032] Specifically, a rotating bearing 5.6 coaxially arranged with the second transmission gear 5.2 is positioned on the cylinder bracket 1.4. The rotating bearing 5.6 is sleeved on the rotating shaft of the second transmission gear 5.2 and cooperates with the cylinder bracket 1.4 to make the second transmission gear 5.2 rotate more smoothly.
[0033] Furthermore, a conical one-way valve 1.6 is provided inside the first gas outlet 1.1, and an elastic member 1.7 (in this embodiment, the elastic member 1.7 is a spring) is provided at one end of the one-way valve 1.6 away from the cylinder body 1.3 to make the one-way valve 1.6 press against the gas outlet 1.5, and a conical groove is provided at the gas outlet 1.5 to match the conical end of the one-way valve 1.6. When the piston 5.4 moves toward the gas outlet 1.5, the gas in the cylinder body 1.3 pushes open the one-way valve 1.6, and the gas flows into the first gas outlet 1.1 through the gas outlet 1.5, and then under the action of the elastic member 1.7, the one-way valve 1.6 is reset and presses against the gas outlet 1.5 again, thereby effectively preventing the gas from flowing back.
[0034] Furthermore, the connecting member 3 is extended in a direction perpendicular to the cylinder body 1.3, and a connecting end 1.8 matching the shape of the connecting member 3 is formed at the end of the cylinder bracket 1.4. Positioning grooves 3.1 that are matched with the connecting end 1.8 are extended from both ends of the connecting member 3, and the connecting end 1.8 is positioned in the positioning groove 3.1. A shockproof ring 6 is sleeved at the matching position between the positioning groove 3.1 and the connecting end 1.8 to position the connecting end 1.8 in the positioning groove 3.1.
[0035] Furthermore, extension parts 1.9 extending in a direction perpendicular to the cylinder body 1.3 are arranged on both sides of the first air outlet 1.1, and shockproof rings 6 are also sleeved on the extension parts 1.9.
[0036] Specifically, the reason why the connecting piece 3 and the extension part 1.9 are perpendicular to and extend from the cylinder body 1.3 is that when the movement is installed in the air pump housing, the extended connecting piece 3 and the extension part 1.9 are positioned in the housing. The anti-vibration ring 6 sleeved on the extension part 1.9 and the connecting piece 3 is to reduce the vibration of the movement and the abnormal sound caused by the vibration when the connecting piece 3 and the extension part 1.9 are matched with the housing.
[0037] Furthermore, the output end at the lower end of the motor 2 is connected to a ventilation fan 2.1 which rotates synchronously therewith.
[0038] Furthermore, the shockproof ring 6 can be made of any flexible material that can undergo elastic deformation and absorb vibration potential energy, such as a rubber ring, a silicone ring, etc.
[0039] Those skilled in the art should understand that the technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0040] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
