Description

Technical Field

[0001] This utility model relates to the field of atomizer equipment technology, and in particular to an atomizer air pump. Background Technology

[0002] Existing nebulizer air pumps generally use shaded-pole motors as the drive source. However, shaded-pole motors have relatively low efficiency, resulting in high energy consumption and operating costs during long-term operation. Furthermore, shaded-pole motors generate significant noise during operation, which can affect patient rest and treatment experience, especially in medical environments. The air pressure provided by shaded-pole motors fluctuates considerably, making it difficult to meet the precise air pressure requirements of medical nebulizers, thus affecting drug nebulization and absorption. In industrial nebulization equipment, unstable air pressure also reduces nebulization efficiency, affecting spraying or humidification quality. Finally, existing nebulizer air pumps are mostly integrated structures, making assembly and disassembly inconvenient. Utility Model Content

[0023] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0024] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.

[0025] like Figure 1-6As shown, an atomizer air pump includes a bracket 1. A DC brushless motor 2 with a rotating shaft passing through the bracket 1 and extending to the upper side of the bracket 1 is provided on the lower side of the bracket 1. An air pump seat 3 is provided on the upper side of the bracket 1. An air pump chamber 31 is provided on the front side of the air pump seat 3. An air pump assembly 4 is provided on the rear side of the air pump seat 3, located behind the air pump chamber 31. An air pump connecting rod 5 with one end extending out of the air pump chamber 31 is provided inside the air pump chamber 31. An eccentric wheel 6 is connected to the rotating shaft end of the DC brushless motor 2. The extended end of the air pump connecting rod 5 is connected to the eccentric wheel 6. A piston 7 is provided at one end of the air pump connecting rod 5 inside the air pump chamber 31, which can move inside the air pump chamber 31 and reciprocate with the air pump connecting rod 5 to realize air intake and air compression. In actual use, the DC brushless motor 2 drives the eccentric wheel 6 to rotate, which in turn drives the air pump connecting rod 5 to reciprocate along the air pump chamber 31 on the air pump base 3. This achieves the air pump assembly 4's intake and compressed air output actions, resulting in a simple structure that is easy to assemble and disassemble. Furthermore, this design uses the DC brushless motor 2 as the drive source for the atomizer air pump. The DC brushless motor offers advantages such as high efficiency, low noise, and long lifespan, significantly reducing energy consumption, noise, and extending the equipment's lifespan. It also provides a more stable air pressure output, ensuring minimal air pressure fluctuations within a set range through precise speed control, meeting the needs of various application scenarios. The DC brushless motor's adjustable speed allows for precise control of flow parameters, improving atomization efficiency and effect.

[0026] like Figure 1-4 As shown, the piston 7 includes a connecting cover 71 connected to the inner end of the air pump connecting rod 5, and a leather cup 72 connected to the connecting cover 71. The connecting cover 71 and the leather cup 72 are driven by the air pump connecting rod 5 to reciprocate within the air pump cavity 31, thereby realizing the air pump assembly 4's intake and compressed air output actions.

[0027] like Figure 1-6As shown, the air pump assembly 4 includes an air pump cover plate 41 located at the rear side of the air pump chamber 31. The air pump cover plate 41 is provided with an air intake chamber 42, an air outlet chamber 43, an air intake pipe 44 communicating with the air intake chamber 42, and an air outlet pipe 45 communicating with the air outlet chamber 43. The rear side of the air pump seat 3 is provided with an air pump seat intake hole 46 and an air pump seat outlet hole 47 communicating with the air pump chamber 31, respectively. The air pump seat intake hole 46 and the air pump seat outlet hole 47 are respectively provided corresponding to the air intake chamber 42 and the air outlet chamber 43. There is a space between the air pump seat 3 and the air pump cover plate 41 to block the air pump seat outlet hole 47 when the piston 7 moves outward to draw in air and to block the air outlet hole 47 when the piston 7 moves inward to discharge air. A silicone sheet 48 is provided on the air pump seat suction hole 46. The silicone sheet 48 is provided with a silicone sheet suction hole 481 and a silicone sheet exhaust hole 482 respectively corresponding to the air pump seat suction hole 46 and the air pump seat exhaust hole 47. An air suction chamber boss 49 is provided in the air suction chamber 42 at the position corresponding to the silicone sheet suction hole 481. An air suction channel 410 communicating with the air suction pipe 44 is provided on the upper side of the air suction chamber boss 49. An air suction channel baffle 483 is provided in the silicone sheet suction hole 481 to block the air suction channel 410 when the piston 7 moves inward to exhaust air. An exhaust channel baffle 484 is provided in the silicone sheet exhaust hole 482 to block the air pump seat exhaust hole 47 when the piston 7 moves outward to intake air. In actual use, when the piston 7 moves outward to draw in air, the baffle 484 of the silicone sheet 48 blocks and closes the air outlet hole 47 of the air pump seat. At this time, air enters the air pump cavity 31 through the air intake pipe 44, air intake channel 410, air intake cavity 42, and air pump seat air intake hole 46. When the piston 7 moves inward to compress air and discharges air, the baffle 483 of the silicone sheet 48 blocks and closes the air intake channel 410. At this time, air is discharged through the air outlet hole 47 of the air pump seat, air outlet cavity 43, and air outlet pipe 45, thus realizing the actions of air pump intake and compressed air discharge.

[0028] like Figure 2 As shown, a limiting protrusion 411 is provided in the air outlet cavity 43 below the air outlet channel baffle 484 to limit the deviation position of the air outlet channel baffle 484, so that the air outlet channel baffle 484 can quickly block and close the air outlet hole 47 of the air pump seat when inhaling.

[0029] like Figure 1-4 As shown, the DC brushless motor 2 is fixed to the bracket 1 by screws 8, which enables the DC brushless motor 2 to be installed quickly; the bracket 1 is provided with shock-absorbing pads 9, which are located at the corners of the bracket 1 to reduce the vibration of the air pump during operation and reduce noise generation.

[0030] In this case, a DC brushless motor with a rated power of 100W and a rated voltage of 24V can be selected, with a speed range of 1000-5000rpm, which can meet the air pressure and flow rate adjustment under different atomization requirements. Meanwhile, the air pump base 3 and air pump assembly 4 can be made of aluminum alloy, which has good heat dissipation performance and structural strength. A cooling fan blade that rotates with the shaft is located on the upper side of the bracket 1 between the DC brushless motor 2 shaft and the eccentric wheel 6, and is connected to the impeller of the air pump via a coupling, ensuring the stability and efficiency of power transmission. The DC brushless motor driver achieves precise control of the motor speed, thereby adjusting the air pressure and flow rate of the air pump. For example, in a medical nebulizer, with the air pressure set to 80-130Kpa, the gas flow rate ≥8L per minute, the 1-5um content greater than 60%, and the atomization volume ≥0.2ml / min, the brushless motor driver automatically adjusts the motor speed according to the feedback signal to maintain a stable output of air pressure and flow rate.

[0031] In this case, a DC brushless motor with a rated power of 200W and a rated voltage of 36V can be selected, suitable for high-power industrial atomization equipment. Simultaneously, an air filter can be installed at the air inlet end of the suction pipe 44 to prevent dust and impurities from entering the air pump, extending the equipment's service life. The air pump housing is also optimized with added heat sinks to improve heat dissipation efficiency. Furthermore, the DC brushless motor driver can be integrated with an industrial automation control system to achieve remote monitoring and adjustment of air pressure and flow rate. For example, in spraying equipment, the air pressure and flow rate can be automatically adjusted based on the spraying area and paint viscosity to achieve the best spraying effect.

Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
