Description
Technical Field
[0001] The utility model belongs to the technical field of inflatable equipment and relates to an air pump, in particular to a low-power consumption controlled air pump. Background Art
[0002] An air pump is a device that removes air from a closed space or adds air to a closed space. Air pumps are mainly divided into electric air pumps and manual air pumps, foot-operated air pumps, electric air pumps, and electric-powered air pumps. They use electricity to continuously compress air and generate air pressure.
[0003] For example, the air pump with publication number CN217462621U includes a first housing, an impeller assembly assembled inside the first housing, a motor connected to the impeller assembly, and a control assembly for controlling the operation of the motor. The control assembly is used to control the motor to drive the impeller assembly to extract external gas, and includes a fixed bracket, a main control board assembled on the fixed bracket, and a sliding member. A slideway for the sliding member to slide is formed between the fixed bracket and the main control board, and a limit block is provided on the side of the fixed bracket facing the main control board, and the limit block allows the sliding member to be operably located in the first position and the second position.
[0004] The air pump will generate heat when used for a long time, but the above-mentioned air pump only dissipates heat through heat conduction through the metal shell, which is inefficient. The heat generated when the motor in the air pump runs at high load accumulates in the pump body and cannot be effectively conducted away, resulting in a decrease in the working performance of the air pump and a shortened working life.

[0007] A further preferred technical solution of the utility model is: a mounting plate is slidably connected in the heat dissipation cavity, the magnetic block is fixedly connected to the mounting plate, and the connecting rod is fixedly connected between the mounting plate and the control board.
[0008] A further preferred technical solution of the utility model is that both the mounting plate and the shell have holes.
[0009] A further preferred technical solution of the utility model is: a plurality of limit blocks are fixedly connected to the inner wall of the shell, and when the magnetic block is separated from the motor, the limit blocks are in abutment with the mounting plate.
[0010] A further preferred technical solution of the utility model is: the fan comprises a rotating shaft and a plurality of fan blades fixedly connected to the rotating shaft, one end of the rotating shaft passes through a lower end cover, a motor is fixedly connected to the lower end cover, and an output end of the motor is fixedly connected to the rotating shaft.
[0011] A further preferred technical solution of the utility model is: an annular groove is provided on the rotating shaft, and sensing elements are fixedly connected in the annular groove and on the control plate. When the two sensing elements are in contact, the motor drives the rotating shaft and the fan blades to rotate.
[0012] A further preferred technical solution of the utility model is: a plurality of clamping blocks are fixedly connected to a side wall of the lower end cover close to the installation cavity, and when the magnetic block is separated from the motor, the control board abuts against the clamping blocks.

[0016] Compared with the prior art, the utility model includes an outer shell and a motor. The outer shell includes a shell body and an upper end cover and a lower end cover. A cavity is formed between the lower end cover and the motor. A fan is fixedly connected in the cavity to divide the cavity into a heat dissipation cavity and an installation cavity. A magnetic block is slidably connected in the heat dissipation cavity. A control board is slidably connected in the installation cavity. The control board and the magnetic block are connected by a connecting rod. A plurality of springs are fixedly connected between the control board and the lower end cover. Therefore, when the temperature of the motor rises, the magnetism of the magnetic block weakens. At this time, the pulling force of the deformed spring is greater than the magnetic force, thereby pulling the magnetic block to separate from the motor. At this time, the fan starts to cool the high-temperature motor. When the temperature drops, the magnetic block is reattached to the motor to turn off the fan. This design enables the motor in the air pump to be cooled in time when it is high temperature, thereby improving the heat dissipation effect and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.
[0025] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.
[0026] Figure 1-Figure 5As shown, a low-power control air pump includes a shell and a motor 16 fixedly connected in the shell, the shell includes a shell 1 and an upper end cover 2 and a lower end cover 3 fixedly connected at both ends of the shell 1, a cavity is formed between the lower end cover 3 and the motor 16, a fan is fixedly connected in the cavity to divide the cavity into a heat dissipation cavity 19 and an installation cavity 20, the heat dissipation cavity 19 is close to the motor 16, a magnetic block 13 that can be attracted to the motor 16 is slidably connected in the heat dissipation cavity 19, a control board 10 is slidably connected in the installation cavity 20, the control board 10 and the magnetic block 13 are connected by a connecting rod 11, and a plurality of springs 9 are fixedly connected between the control board 10 and the lower end cover 3.
[0027] Figure 2-Figure 5 As shown, after using the air pump for a long time, the temperature of the motor 16 increases. At this time, the magnetic block 13 adsorbed on the motor 16 absorbs heat and its magnetism decreases until the magnetism of the magnetic block 13 is less than the pulling force of the deformed spring 9. The deformed spring 9 pulls the control board 10, the connecting rod 11 and the magnetic block 13 to slide toward the side close to the installation cavity 20. At this time, the magnetic block 13 is separated from the motor 16 and the control board 10 turns on the fan, so that the fan can dissipate the heat of the motor 16 with excessive temperature in time. This design makes the interior of the air pump also have a heat dissipation structure, thereby avoiding heat accumulation in the air pump and improving the heat dissipation effect and heat dissipation efficiency of the air pump.
[0028] Figure 2-Figure 5 As shown, two connecting rods 11 are provided, so that when the spring 9 pulls the control board 10 to slide, the connecting rod 11 drives the magnet 13 to slide and can make the magnet 13 evenly stressed, thereby preventing the magnet 13 from tilting during the sliding process. Similarly, two springs 9 are also provided, so that the control board 10 can be evenly stressed when sliding.
[0029] Figure 2-Figure 5 As shown, a mounting plate 12 is slidably connected in the heat dissipation cavity 19, a groove 17 is provided on the mounting plate 12, a magnetic block 13 is located in the groove 17, and a connecting rod 11 is fixedly connected between the mounting plate 12 and the control board 10. This design can facilitate the connection between the connecting rod 11 and the magnetic block 13, and when the magnetic block 13 is attracted to the motor 16, the mounting plate 12 is fitted with the motor 16, thereby increasing the contact area.
[0030] Figure 2-Figure 5 As shown, both the mounting plate 12 and the housing 1 have holes 14, so that when the fan is started, air can circulate alternately through the holes 14, thereby facilitating heat dissipation.
[0031] Figure 2-Figure 5As shown, a plurality of limit blocks 15 are fixedly connected to the inner wall of the shell 1. When the magnetic block 13 is separated from the motor 16, the limit blocks 15 abut against the mounting plate 12. This design can limit the sliding range of the mounting plate 12 and the magnetic block 13, and prevent the mounting plate 12 from abutting against the fan and thus escaping from the magnetic attraction range of the magnetic block 13 when the spring 9 pulls the mounting plate 12 to slide. When the magnetic block 13 separates from the mounting plate 12 and abuts against the limit blocks 15, the magnetic block 13 is still within the magnetic attraction range, thereby facilitating the re-adsorption of the motor 16 and the magnetic block 13 after cooling down.
[0032] Figure 2-Figure 5 As shown, the fan includes a rotating shaft 5 and a plurality of fan blades 7 fixedly connected to the rotating shaft 5. One end of the rotating shaft 5 passes through the lower end cover 3, and a motor 4 is fixedly connected to the lower end cover 3. The output end of the motor 4 is fixedly connected to the rotating shaft 5. When the fan is started, the output end of the motor 4 drives the rotating shaft 5 and the fan blades 7 to rotate, thereby accelerating the air flow and accelerating the heat dissipation effect.
[0033] Figure 2-Figure 5 As shown, an annular groove 18 is provided on the rotating shaft 5, and a sensing member 6 is fixedly connected in the annular groove 18 and on the control board 10. When the two sensing members 6 are in contact, the motor 4 drives the rotating shaft 5 and the fan blades 7 to rotate. When the spring 9 pulls the control board 10 to slide toward the side close to the motor 4, the sensing member 6 is in contact to start the motor 4. At this time, the motor 4 is turned on to drive the fan blades 7 to rotate. When the magnetic block 13 and the motor 16 are attracted, the two sensing members 6 are separated, the motor 4 is turned off, and the fan blades 7 stop rotating. This design serves to control the switch of the motor 4.
[0034] Figure 2-Figure 5 As shown, a plurality of blocks 8 are fixedly connected to a side wall of the lower end cover 3 close to the installation cavity 20. When the magnetic block 13 is separated from the motor 16, the control board 10 abuts against the block 8. At this time, the two sensing parts 6 are in contact. This design serves to limit the sliding range of the control board 10 and ensures that the two sensing parts 6 can accurately contact after the spring 9 pulls the control board 10 to slide.

This article uses specific examples to illustrate the principle and implementation of the utility model. The description of the above embodiments is only used to help understand the utility model and its core ideas.
