Description

Technical Field

[0001] The utility model relates to the field of air pumps, in particular to an air pump shock absorbing structure. Background Art

[0002] An air pump is an "air pump", a device that removes air from a closed space or adds air to a closed space. The basic principle of an air pump is to use mechanical or other energy to transport gas from a low-pressure area to a high-pressure area, thereby compressing or moving the gas.

[0003] Atomizer is an application of air pump device. The air pump device in general atomizer does not have a shock absorption function, which causes vibration and noise in the operation of the air pump. When the motor speed is high, it may cause the atomizer as a whole to move on the desktop. Therefore, it is necessary to solve the impact caused by the vibration of the air pump device during operation. Utility Model Content

[0004] Since existing air pumps generally do not have a shock-absorbing function, the air pump in this case is mainly used for atomizers, but the structure should be widely applicable to other devices that require an air pump.

[0005] The technical solution adopted by the utility model is: an air pump shock-absorbing structure, comprising a bottom shell and a base, an air pump device is arranged on the base, and multiple groups of shock-absorbing mechanisms are arranged between the base and the bottom shell.

[0006] Furthermore, the shock absorbing mechanism comprises a through hole, a spring shaft, a clamping block, a limiting cap, a spring bar and a clamping slot. The surface of the base is provided with a through hole, and the spring shaft passes through the interior of the through hole.

[0007] Furthermore, an air cabin is installed on the upper surface of the base, a cam connecting rod is installed on the side surface of the air cabin, a motor is installed between the cam connecting rod and the base, an air inlet pipe is installed on the side surface of the air cabin, and an air outlet pipe is installed on the side surface of the air cabin.

[0008] Furthermore, three groups of through holes and spring shafts are provided, and the spring shafts are slidably connected to the base through the through holes.

[0009] Furthermore, a clamping block is connected to the bottom of the spring shaft, the spring shaft and the clamping block are an integrated structure, and a clamping groove is connected to the upper surface of the bottom shell close to the clamping block.

[0010] Furthermore, the positions of the card block and the card slot correspond one to one, and a card engagement structure is formed between the card block and the card slot.

[0011] Furthermore, a limiting cap is sleeved on the surface of the spring shaft, a spring bar is sleeved on the surface of the spring shaft, and the spring bar is located on the bottom side of the limiting cap.

[0012] Furthermore, the limiting cap and the spring shaft are slidably connected.

[0013] Furthermore, an elastic telescopic structure is formed between the limiting cap and the spring bar.

[0014] Compared with the prior art, the present application has the following beneficial effects: when the motor speed is high, the atomizer as a whole will be displaced on the desktop. At the same time, due to vibration, when the motor is running and rotating, the base can be driven to vibrate. When the base vibrates, the through hole can be driven to slide longitudinally on the surface of the spring shaft. At the same time, when the base moves longitudinally, the limiting cap can be driven to move longitudinally. The limiting cap can slide longitudinally on the surface of the spring shaft and squeeze the spring bar when it moves longitudinally. The spring bar can be compressed when it is squeezed. When the spring bar is compressed, it can be buffered by its own elastic force. In this way, the vibration amplitude of the limiting cap can be reduced, thereby reducing the vibration amplitude of the base, and thus reducing the abnormal sound and noise caused by the vibration of the base.

[0015] In summary, the component design improvements in the above technical solutions can effectively solve the problem of abnormal sound and noise caused by motor vibration. Through the design of through holes, spring shafts, clamps, limit caps, spring bars and slots, the vibration amplitude of the base driven by the motor operation can be reduced, thereby reducing noise, thereby improving the service life and performance of the air pump and bringing a better experience to users.

[0028] This application proposes an air pump shock absorbing structure, see the attached Figures 1 to 5 As shown, the air pump shock absorbing structure in the present application scheme includes a bottom shell 1, an upper shell 2 and a base 3, the upper shell 2 is installed on the top of the bottom shell 1, the upper surface of the bottom shell 1 is provided with a base 3, the upper surface of the base 3 is provided with an air chamber 4, the side surface of the air chamber 4 is provided with a cam connecting rod 5, a motor 6 is installed between the cam connecting rod 5 and the base 3, the side surface of the air chamber 4 is provided with an air inlet pipe 7, the side surface of the air chamber 4 is provided with an air outlet pipe 8, a shock absorbing mechanism is provided between the base 3 and the bottom shell 1, when the motor 6 is running and rotating, it can drive the base 3 to vibrate, when the base 3 vibrates, it can drive the through hole 9 to slide longitudinally on the surface of the spring shaft 10, at this time, the shock absorbing mechanism can reduce the longitudinal vibration amplitude of the base 3, thereby effectively reducing the abnormal sound and noise caused by the vibration of the base 3.

[0029] In addition, the shock absorbing mechanism includes a through hole 9, a spring shaft 10, a block 11, a limiting cap 12, a spring bar 13 and a slot 14. The surface of the base 3 is provided with a through hole 9, and the interior of the through hole 9 is penetrated by a spring shaft 10. The through hole 9 and the spring shaft 10 are provided in three groups. The spring shaft 10 is slidably connected to the base 3 through the through hole 9. When the base 3 vibrates, the through hole 9 can be driven to slide longitudinally on the surface of the spring shaft 10, so that the movement direction of the base 3 during vibration can be limited, thereby effectively ensuring that the spring bar 13 can be compressed when the base 3 vibrates.

[0030] Preferably, a clamping block 11 is connected to the bottom of the spring shaft 10, and the spring shaft 10 and the clamping block 11 are an integrated structure. A clamping slot 14 is connected to the upper surface of the bottom shell 1 near the clamping block 11. The positions of the clamping block 11 and the clamping slot 14 correspond one to one. A clamping structure is formed between the clamping block 11 and the clamping slot 14. The position of the spring shaft 10 can be fixed by the clamping between the clamping block 11 and the clamping slot 14, so that the base 3 can be installed on the upper surface of the bottom shell 1.

[0031] Furthermore, a limiting cap 12 is sleeved on the surface of the spring shaft 10, and a spring bar 13 is sleeved on the surface of the spring shaft 10. The spring bar 13 is located on the bottom side of the limiting cap 12. The limiting cap 12 and the spring shaft 10 are slidably connected, and an elastic telescopic structure is formed between the limiting cap 12 and the spring bar 13. The limiting cap 12 can move longitudinally on the surface of the spring shaft 10 and squeeze the spring bar 13. The spring bar 13 can be compressed when squeezed, and the spring bar 13 can be buffered by its own elastic force when compressed, so that the vibration amplitude of the limiting cap 12 can be reduced, thereby reducing the vibration amplitude of the base 3.

[0032] Through the specific implementation methods described above, the air pump shock absorbing structure in the present application can achieve the following effects: when the motor 6 rotates at a high speed, it will drive the atomizer as a whole to move on the desktop. At the same time, due to vibration, when the motor 6 is running and rotating, it can drive the base 3 to vibrate. When the base 3 vibrates, it can drive the through hole 9 to slide longitudinally on the surface of the spring shaft 10. At the same time, when the base 3 moves longitudinally, it can drive the limiting cap 12 to move longitudinally. The limiting cap 12 can slide longitudinally on the surface of the spring shaft 10 and squeeze the spring bar 13 when it moves longitudinally. The spring bar 13 can be compressed when it is squeezed. When the spring bar 13 is compressed, it can be buffered by its own elastic force. In this way, the vibration amplitude of the limiting cap 12 can be reduced, thereby reducing the vibration amplitude of the base 3, and thus reducing the abnormal sound and noise generated by the vibration of the base 3.
