[0064] The present invention provides an air pump module 100.

[0065] Referring to Figures 1 to 7 , in an embodiment of the present invention, the air pump module 100 includes a housing 1, a bracket assembly 2, an air pump 3, and a cooling fan 4. An installation cavity is formed inside the housing 1, and the housing 1 is provided with an air inlet 111 and an air outlet 121 communicating with the installation cavity; the bracket assembly 2 is detachably disposed in the installation cavity, and the bracket assembly 2 is detachably connected to the housing 1; an elastic foot 33 is provided at the bottom of the air pump 3, and the air pump 3 is carried on the bracket assembly 2 through the elastic foot 33; the cooling fan 4 is disposed in the housing 1 and is opposite to the air outlet 121, and is used to drive air to flow into the installation cavity from the air inlet 111 and then flow out from the air outlet 121.

[0066] The air pump module 100 proposed in this application is used to generate air pressure to achieve two functions of suction and blowing, and can be used as a component of a blowing assembly in laser processing equipment such as laser engraving machines, laser marking machines, and laser cutting machines, or in machining equipment that uses machining tools for processing; it can be used to blow away dust and other impurities in the processing area to avoid the accumulation of dust and other impurities in the processing area and affecting the processing; in laser processing equipment, it can also prevent dust and other impurities from adhering to the optical path components of the laser head, thereby avoiding affecting the laser emission and laser processing.

[0067] Specifically, the air pump module 100 includes a housing 1 as an installation base. An installation cavity is formed in the housing 1. The housing 1 is generally in a cuboid structure, and can also be in a cylindrical structure or other polygonal structures, which is not limited here. An air inlet 111 and an air outlet 121 communicating with the installation cavity are provided on the housing 1. External air flow can enter the installation cavity from the air inlet 111, and the gas in the installation cavity can be discharged outwards from the air outlet 121. Among them, the air outlet 121 is provided on one of the walls of the housing 1, and can be provided on one of the top wall, bottom wall, and side wall of the housing 1; the air outlet 121 can be set as a single open port, or can be set as multiple air outlets 121 or air outlet grilles and other structures; the air inlet 111 can be provided on one of the walls of the housing 1, or the air inlet 111 can be provided on two or more walls of the housing 1. For example, the air inlet 111 is opened on different side walls, or the air inlet 111 can be provided on at least two of the side wall, bottom wall, and top wall; the air inlet 111 can be set as a single open port, or can be set as multiple air inlets 111 or air inlet grilles and other structures; the air inlet 111 and the air outlet 121 are usually located on different walls.

[0068] The bracket assembly 2, as a component in the air pump module 100 for supporting and installing the air pump 3, is detachably connected to the housing 1, and the bracket assembly 2 can be removed from the installation cavity. The bracket assembly 2 can include only a bottom bracket 21 for carrying the air pump 3, or can also be provided with a bottom bracket 21 and a top bracket 22 at the same time. The shape of the bracket assembly 2 can be adapted to the shape of the air pump 3, or can be different from the shape of the air pump 3.

[0069] The air pump 3, as the main component in the air pump module 100 that generates air pressure and realizes air intake and blowing, is generally an electric air pump 3. The piston in the piston chamber 311 is driven by a motor to reciprocate to realize air intake and blowing. The motor can be a brushless motor or a brushed motor. The air pump 3 is detachably connected to the bracket assembly 2 and can be fixed in the installation cavity of the housing 1 through the bracket assembly 2; it can be combined with the bracket assembly 2 into a whole to be jointly installed in the installation cavity or removed from the installation cavity. After the air pump 3 is installed in the installation cavity of the housing 1 together with the bracket assembly 2, the intake pipe 35 and the outlet pipe 36 of the air pump 3 can both extend to the outside of the housing 1 to prevent the housing 1 from affecting the air intake of the air pump 3; in addition, the intake pipe 35 of the air pump 3 can also be located in the installation cavity. Since the external air flow can enter the installation cavity from the air inlet 111, it will not affect the air intake of the air pump 3 either. In some embodiments, an air vent 112 for supplying air to the air pump 3 can also be provided on the housing 1, which not only eliminates the need to extend the intake pipe 35 of the air pump 3 outward, but also avoids the interference between the air intake flow of the air pump 3 and the cooling air flow driven by the cooling fan 4, thereby preventing the air flow in the installation cavity from being disordered and affecting the air intake and cooling of the air pump 3.

[0070] At least two elastic feet 33 are provided at the bottom of the air pump 3. The number of elastic feet 33 can be two, three, four or more than four, and each elastic foot 33 is evenly distributed to stably support the air pump 3. The elastic feet 33 are provided on the bracket assembly 2. When the air pump 3 vibrates during operation, the elastic feet 33 can generate elastic deformation to absorb the vibration of the air pump 3 and reduce the transmission of vibration energy to the housing 1, so that the external vibration influence of the air pump module 100 can be weakened, playing a good shock-absorbing role. Among them, the elastic feet 33 can be made of materials such as silica gel, rubber or silicone rubber.

[0071] The cooling fan 4, as the air flow driving component in the air pump module 100, can be an axial flow fan or a vortex fan; the cooling fan 4 can be arranged in the installation cavity with the air flow outlet of the cooling fan 4 facing the air outlet 121; or the cooling fan 4 can be arranged outside the installation cavity with the air flow inlet of the cooling fan 4 facing the air outlet 121. With these setting methods, the cooling fan 4 can drive the air flow in the installation cavity to flow out through the air outlet 121 to take away the heat of the air pump 3, and the relatively cooler external air flow flows into the installation cavity through the air inlet 111 for replenishment and exchanges heat with the air pump 3, thereby improving the heat dissipation efficiency of the air pump module 100 and preventing problems such as overheating of the air pump 3 or other components caused by the accumulation of heat in the installation cavity due to untimely heat dissipation of the air pump 3, and thus avoiding the problem of unstable performance of the air pump module 100 due to overheating.

[0072] Therefore, it can be understood that in the technical solution of the present utility model, the air pump 3 is fixed in the installation cavity of the outer shell 1 through the support assembly 2. The support assembly 2 is detachably connected to the outer shell 1. The air pump 3 and the support assembly 2 can be connected and then the whole can be installed in the installation cavity. An elastic support foot 33 is arranged at the bottom of the air pump 3 and abuts against the support assembly 2. The elastic support foot 33 can absorb the vibration of the air pump 3 by its elastic deformation, so that most of the vibration of the air pump 3 is absorbed, thereby reducing the vibration of the air pump module 100 to the outside when the air pump 3 is running.

[0073] An air inlet 111 and an air outlet 121 are arranged on the outer shell 1, and a cooling fan 4 is arranged inside the outer shell 1. Thus, the air flow in the installation cavity can be discharged outwards through the air outlet 121 by the cooling fan 4, and the external air flow flows into the installation cavity through the air inlet 111. The continuously flowing air flow can take away the heat of the air pump 3 and improve the heat dissipation efficiency of the air pump 3. That is to say, in the technical solution of the present utility model, by arranging the elastic support foot 33 and the cooling fan 4 to reduce the vibration of the air pump 3 and improve the heat dissipation efficiency of the air pump 3, when using an air pump 3 with a higher air flow rate, it is also possible to avoid large vibrations of the air pump module 100 and avoid performance degradation due to insufficient heat dissipation.

[0074] Please refer to Figures 5 to 10 , in an embodiment, the support assembly 2 includes a bottom support 21 and a top support 22. The bottom support 21 is detachably connected to the outer shell 1. The bottom support 21 is provided with a support member 23, and the elastic support foot 33 is carried on the support member 23. The top support 22 is arranged above the bottom support 21 and is oppositely arranged with the bottom support 21 to enclose an installation space 25, and the air pump 3 is located in the installation space 25.

[0075] In this embodiment, the support assembly 2 includes a bottom support 21 and a top support 22 that are oppositely arranged and connected to each other along the height direction of the air pump module 100. The bottom support 21 is detachably connected to the outer shell 1. For example, it can be connected by bolts, or can be connected to the outer shell 1 by means of buckles, etc. The bottom support 21 is provided with at least one support member 23. The support member 23 can be integrally formed with the bottom support 21, or can be installed on the bottom support 21. For example, the support member 23 is connected to the bottom support 21 by at least one of bolt connection, buckle connection, plug connection, magnetic attraction connection, etc. The elastic support foot 33 of the air pump 3 is supported on the support member 23. The elastic support foot 33 can be directly placed on the support member 23, or the elastic support foot 33 can be connected to the support member 23, both of which can make the air pump 3 carried on the bottom support 21.

[0076] The top bracket 22 is disposed above the bottom bracket 21 and is detachably connected to the bottom bracket 21. An installation space 25 is formed between the top bracket 22 and the bottom bracket 21, which can provide good protection for the air pump 3 and reduce the risk of the air pump 3 directly colliding with the housing 1 or other components. In some embodiments, the top bracket 22 can also be used to install other devices in the air pump module 100; for example, the electronic control module 7 in the following embodiment.

[0077] Referring to Figure 7 and Figure 12 , in one embodiment, the elastic feet 33 are detachably connected to the support member 23. Among them, the elastic feet 33 can be detachably connected to the support member 23 by means of plugging, clamping or screw connection; this setting method can prevent the elastic feet 33 from falling off or being misaligned from the support member 23, thereby improving the connection strength and relative position stability between the air pump 3 and the bracket assembly 2.

[0078] Referring to Figure 7 , Figure 11 and Figure 12 , in one embodiment, the support member 23 is provided with a support plate 231 disposed opposite to the air pump 3, and the support plate 231 is provided with a communicating clamping hole 232, and a part of the elastic feet 33 are inserted into the clamping hole 232.

[0079] In this embodiment, the elastic feet 33 at the bottom of the air pump 3 are inserted into the clamping holes 232 formed in the support member 23, so that the elastic feet 33 are detachably connected to the support member 23; the clamping holes 232 can also limit the elastic feet 33, thereby preventing the elastic feet 33 from being misaligned or falling off on the support member 23, improving the connection stability and relative position stability of the elastic feet 33 and the feet of the support member 23, and ensuring that the elastic feet 33 can stably play a shock-absorbing role.

[0080] Referring to Figures 11 to 13 , in one embodiment, the side wall of the elastic foot 33 is provided with a clamping groove 331, and the edge of the clamping hole 232 is located in the clamping groove 331.

[0081] In this embodiment, a clamping groove 331 is provided on the side wall of the elastic support leg 33. The cross-sectional dimension of the elastic support leg 33 at the clamping groove 331 is the same as or approximately the same as the opening dimension of the clamping hole 232, and the cross-sectional dimension of the elastic support leg 33 at the position without the clamping groove 331 is greater than the opening dimension of the clamping hole 232. When the elastic support leg 33 is connected to the support member 23, the elastic support leg 33 is inserted into the clamping hole 232 until the clamping groove 331 is located at the position of the clamping hole 232. At this time, the part of the structure of the elastic support leg 33 below the clamping groove 331 is located below the support plate 231 of the support member 23, and the part of the structure of the elastic support leg 33 above the clamping groove 331 is located above the support plate 231. A part of the support plate 231 on the peripheral side of the edge of the clamping hole 232 is clamped in the clamping groove 331. With such a setting, the elastic support leg 33 cannot move easily in the height direction, making the connection strength between the elastic support leg 33 and the support member 23 higher and improving the overall structural stability.

[0082] In this embodiment, since the elastic support leg 33 has elasticity, the elastic support leg 33 can be directly inserted into the clamping hole 232 in the axial direction of the clamping hole 232; alternatively, a limiting groove 233 can be provided on the support plate 231 for the elastic support leg 33 to enter and exit the clamping hole 232 as in the following embodiment, which is not limited herein.

[0083] Refer to in combination Figures 11 to 13 In an embodiment, the support plate 231 is further provided with a limiting groove 233 communicating with the clamping hole 232. One end of the limiting groove 233 away from the clamping hole 232 penetrates through to the edge of the support plate 231. Along the width direction of the limiting groove 233, the groove width of the limiting groove 233 is smaller than the aperture of the clamping hole 232, and the elastic support leg 33 can enter and exit the clamping hole 232 along the limiting groove 233.

[0084] In this embodiment, a clamping hole 232 and a limiting groove 233 communicating with each other are provided on the support plate 231 of the support member 23. The limiting groove 233 penetrates from the clamping hole 232 to the edge of the support plate 231. The limiting groove 233 can be used as a channel for the elastic support leg 33 to enter and exit the clamping hole 232.
