[0003] However, since the motor and impeller convert electrical energy or mechanical energy into gas pressure energy during operation, a large amount of heat is inevitably generated, causing circumferential heating of the air pump, which affects the hand-holding comfort. At the same time, high temperature will accelerate the thermal aging of various parts and increase the internal loss of the motor, reducing the working efficiency of the motor, that is, shortening the service life of the air pump as a whole.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] like Figure 1-Figure 7As shown, the utility model discloses an air pump with heat dissipation function, including a shell 1 and an impeller 2, a motor 3, a mounting seat 4, a switch 5 and a cover body 6 arranged in the shell 1, the impeller 2 is located below the mounting seat 4, the motor 3 is located above the mounting seat 4 and is linked with the impeller 2, the switch 5 is used to start and close the motor 3 and is located above the motor 3 (the connection relationship is the prior art and is not specifically described here), the cover body 6 is provided with an air suction port 61, the bottom of the shell 1 is provided with an air outlet 11, and the motor 3 is started by starting the switch 5. After the operation, the output shaft of the motor 3 can drive the impeller 2 to rotate. When the impeller 2 rotates in the shell 1, a low-pressure area will be formed near the center of the impeller 2. Since the external atmospheric pressure is greater than the pressure in the low-pressure area in the shell 1, the gas will be sucked into the center of the impeller 2 from the suction port to achieve suction. As the impeller 2 rotates, the gas is accelerated outward along the direction of the impeller 2 under the action of centrifugal force, and further increases speed and reduces pressure along the channel in the shell 1 and is finally discharged to the outside of the pump through the exhaust port, thereby achieving the purpose of extracting and conveying gas (this is the prior art, and the gas is not used in this invention). The housing 6 is provided with a liquid injection bin 62 and a plurality of conduits 63 extending in the up-down direction. The housing 1 is provided with a mounting groove 12 corresponding to each conduit 63. Each conduit 63 is interconnected with the liquid injection bin 62 and is located in the corresponding mounting groove 12. One end of each conduit 63 is fixedly connected to the housing 1 by bonding, magnets, etc. Since each conduit 63 is interconnected with the liquid injection bin 62 and each conduit 63 is located in the corresponding mounting groove 12, therefore: 1. After the air pump is assembled, at this time, since each conduit 63 is divided 1. The coolant is placed in the corresponding installation groove 12, so each conduit 63 can be located in the circumference of the outer shell 1, thereby indirectly improving the assembly stability of the outer shell 1 and the wind shield; 2. The coolant can reach each conduit 63 after being placed from the liquid filling tank 62, so one end of the conduit 63 located in the corresponding installation groove 12 is fixed to the outer shell 1, so as to absorb the heat generated by the internal heat source of the air pump and transfer the heat to achieve heat dissipation and cooling; 3. Since the length direction of each conduit 63 extends up and down, the contact area with the outer shell 1 can be increased, thereby improving the heat dissipation efficiency.

[0032] Among them, it also includes an upper connecting tube 7 located between adjacent conduits 63, each of the upper connecting tubes 7 is arranged in an arc shape with its opening facing downward, and the housing 1 is provided with a protruding positioning plug 13 between adjacent mounting grooves 12. 1. Since each of the upper connecting tubes 7 is arranged in an arc shape with its opening facing downward, the axial length of each of the upper connecting tubes 7 is increased compared with the shape in which the length extends left and right, thereby increasing the axial contact area between each of the upper connecting tubes 7 and the housing 1; 2. Since each of the upper connecting tubes 7 is located between adjacent conduits 63, the arrangement of each of the upper connecting tubes 7 increases the flow path of the coolant, that is, increases the contact area with the housing 1; 3. When the coolant is transferred from When the liquid is injected into the filling tank 62 and flows into each conduit 63, the existence of each upper connecting tube 7 makes it possible for the coolant to flow to other conduits 63 through the upper connecting tube 7 located between adjacent conduits 63 if the coolant does not flow evenly to each conduit 63, so that the coolant can reach each conduit 63 more efficiently and smoothly; 4. Due to the existence of each positioning plug 13, when each conduit 63 is placed in the corresponding installation groove 12, since the material of the tube is usually soft, that is, it is easy to deform under force, the setting of each positioning plug 13 makes it possible for the adjacent conduits 63 to not move and collide at will when each conduit 63 is installed, and to separate from the corresponding installation groove 12 during use, thereby providing convenience for assembly.

[0033] Preferably, it also includes a lower connecting tube 8 located between adjacent conduits 63, each of which is located on the cover body 6 and is interconnected with the liquid filling tank 62. Therefore, the coolant flowing from the liquid filling tank 62 to each conduit 63 can not only flow to the outside of each conduit 63 through the connecting position between the liquid filling tank 62 and each conduit 63, but also flow to each conduit 63 and the upper connecting tube 7 through each lower connecting tube 8, thereby allowing the coolant in the liquid filling tank 62 to reach each conduit 63 more efficiently and smoothly.

[0034] Each of the conduits 63 is provided with a first magnet 631, and each of the mounting grooves 12 of the housing 1 is provided with a second magnet 14. After the air pump is assembled, at this time: 1. After each conduit 63 is placed in the corresponding mounting groove 12, each first magnet 631 is attracted to the corresponding second magnet 14 in the housing 1, so that each conduit 63 can be stably located on the housing 1 during use to achieve heat dissipation of the housing 1; 2. At the same time, the cooperation between each first magnet 631 and the second magnet 14 can be attracted when each conduit 63 is installed in the mounting groove 12, thereby achieving the position determination of each conduit 63 in the corresponding mounting groove 12; 3. Since the magnet connection is a detachable connection method, when the air pump needs to be repaired, the air pump can be disassembled by separating the first magnet 631 of each conduit 63 from the corresponding second magnet 14, and during use, the conduit 63 stably located in the corresponding mounting groove 12 allows the housing 1 and the cover body 6 of the air pump to be stably assembled together under the action of each conduit 63.

[0035] In addition, the liquid filling bin 62 also includes a cover body 621, and the liquid filling bin 62 includes a liquid filling port 622 that is interconnected with each lower connecting tube 8, and the circumference of the cover body 621 is against the inner wall of the liquid filling bin 62, and the cover body 621 and the liquid filling bin 62 are detachably connected by means of threads, snaps, etc. 1. Since the cover body 621 and the liquid filling bin 62 are detachably connected, the coolant can be poured into the liquid filling bin 62 by separating the liquid filling bin 62 from the cover body 621, and flows to each lower connecting tube 8, the conduit 63 and the upper connecting tube 7 through each liquid filling port 622; 2. Since the circumference of the cover body 621 is against the inner wall of the liquid filling bin 62, after the coolant is poured into each liquid filling port 622, the cover body 621 and the inner wall of the liquid filling bin 62 are against each other, so that the coolant cannot accumulate in the liquid filling bin 62, thereby making it difficult for the coolant to accumulate in the liquid filling bin 62 during carrying and use, thereby reducing the possibility of coolant leakage.

[0036] Preferably, the cover body 621 is circumferentially provided with external threads 6211. 1. Since the cover body 621 is circumferentially provided with external threads 6211, the cover body 621 can be separated from the liquid filling tank 62 by rotating the cover body 621, so that the coolant can be injected into each liquid filling port 622 and flow into each lower connecting tube 8 and conduit 63, and upper connecting tube 7; 2. At the same time, in addition to the advantage of detachability, the threaded fitting can ensure the stability of the connection and prevent loosening due to vibration, impact and the like.

[0037] Among them, the mounting seat 4 includes an extension portion 41 at the top and a limiting plate 42 located below the extension portion 41, the cover body 6 includes a mating portion 64 extending upward, and the limiting plate 42 is provided with a mating groove 421 for the mating portion 64 to be installed, and the circumference of the extension portion 41 is abutted against the inner wall of the outer shell 1. During the assembly process of the air pump, since the extension portion 41 at the bottom of the mounting seat 4 will be inserted into the outer shell 1, the mating portion 64 at the bottom of the cover body 6 will abut against the limiting plate 42 of the mounting seat 4, thereby realizing the radial position determination of the cover body 6, the mounting seat 4 and the outer shell 1, and providing convenience for assembly.

[0038] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
