Description
Technical field
The utility model relates to a kind of electric pump, particularly a kind of vehicle air horn electric pump.
Background technique
Air horn gives great volume owing to having, easy to use, be widely used on the surface carrier such as boats and ships, vehicle as a kind of sound signal generating apparatus.Existing air horn generally comprises speaker body and air horn electric pump, the structure of speaker body generally includes trumpet projector, the diaphragm fixed tray be fixed on trumpet projector end, diaphragm is provided with in fixed tray inner chamber, described diaphragm edge is fixed, middle part can quiveringly in fixed tray inner chamber, and fixed tray inner chamber is isolated a pronunciation chamber, trumpet projector end and described pronunciation chamber UNICOM, described speaker body be also provided with one with the intake duct of described pronunciation chamber UNICOM.Air horn electric pump is connected with described speaker body intake duct, by passing into forced draft in intake duct, makes diaphragm vibration occur thus sound.Therefore, the air pressure size of air horn electric pump and working efficiency most important.
Summary of the invention
The purpose of this utility model is the vehicle air horn electric pump that a kind of pressure is large, efficiency is high in order to provide.
To achieve these goals, the utility model discloses a kind of vehicle air horn electric pump, comprise shell, micromachine and impeller, it is characterized in that: described shell comprises inner barrel and outer cylinder body, described inner barrel is arranged in outer cylinder body, interlayer is formed between outer cylinder body and inner barrel, described impeller is arranged in the airtight inner chamber of described inner barrel prejudicially, described micromachine drives impeller is rotatably connected, described impeller comprises a solid of rotation and some blades, described solid of rotation cylinder is provided with axial slot, spring or elastic spring is provided with in described slot, one side of described blade is slidably matched and is plugged in slot and is against on spring or elastic spring, described spring or elastic spring make another side of described blade and inner barrel inwall elasticity be affixed, described outer cylinder body barrel is provided with UNICOM's through hole that is extraneous and interlayer and forms inlet hole, and described inner barrel barrel is provided with the linked hole of UNICOM's inner barrel inner chamber and interlayer, described shell is also provided with UNICOM's inner barrel inner chamber and extraneous passage are formed air outlet hole.
The utility model makes another side of blade and inner barrel inwall elasticity be affixed due to described spring or elastic spring, is now not easy the phenomenon that leaks air when rotated, and therefore in air-breathing and exhaust process, efficiency is higher, and output gas flow pressure is larger, and loudspeaker are louder.
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model specific embodiment surface structure schematic diagram;
Accompanying drawing 2 is one of the utility model specific embodiment internal structure sectional view;
Accompanying drawing 3 is the utility model specific embodiment internal structure sectional view two;
Accompanying drawing 4 is the utility model specific embodiment internal structure sectional view three.
Embodiment
As Figure 1-4, vehicle air horn electric pump comprises shell 1, micromachine 2 and impeller 3, described shell 1 comprises inner barrel 101 and outer cylinder body 102, described inner barrel 101 and outer cylinder body 102 are preferably cylindrical shape, described inner barrel 101 is arranged in outer cylinder body 102, interlayer 103 is formed between outer cylinder body 102 and inner barrel 101, described impeller 3 is arranged in the airtight inner chamber of described inner barrel 101 prejudicially, and described outer cylinder body 102 is provided with end cap 4 makes the inner chamber of interlayer 103 and inner barrel 101 form airtight space.As shown in Figure 3, described impeller 3 is preferably affixed with described inner barrel 101 barrel, makes circumferencial direction that the space of described interlayer 103 rotates along impeller 3 from small to large, more from big to small.As shown in Figure 3-4, described impeller 3 comprises a solid of rotation 301 and some blades 302, solid of rotation 301 is cylindrical, described solid of rotation 301 cylinder is provided with axial slot 303, spring 5 or elastic spring is provided with in described slot 303, one side of described blade 302 is slidably matched and is plugged in slot 303 and is against on spring 5 or elastic spring, when adopting spring 5, can arrange one or more springs 5 in each slot 303, select elastic spring, described elastic spring can be made up of the elongated metal reed of width and slot 303 Spielpassung, be placed in bottom slot 303, described elastic spring makes another side of described blade 302 and inner barrel 101 inwall elasticity be affixed, described interlayer 103 is divided into some spaces, impeller 3 described in this specific embodiment is provided with four blades 302, four blades 302 distribute along solid of rotation 301 even circumferential, described interlayer 103 is divided into four spaces, described micromachine 2 is arranged on one end of inner barrel 101, the rotating shaft of micromachine 2 is connected with solid of rotation 301, drives impeller 3 is rotatably connected, described outer cylinder body 102 barrel is provided with UNICOM's through hole that is extraneous and interlayer 103 and forms inlet hole 104, described inner barrel 101 barrel is provided with the linked hole 105 of UNICOM's inner barrel 101 inner chamber and interlayer 103, described shell 1 is also provided with UNICOM's inner barrel 101 inner chamber and extraneous passage are formed air outlet hole 106, described inlet hole 104 and air outlet hole 106 are preferably arranged on the both sides that impeller 3 and inner barrel 101 barrel are affixed place,
The working principle of this vehicle air horn electric pump is as follows: after energising, solid of rotation 301 is with moving vane 302 to rotate in inner barrel 101 under the driving of micromachine 2, because the side of blade 302 and inner barrel 101 inwall elasticity are affixed, space between two adjacent blades 302 is confined space, and the circumferencial direction that the space of interlayer 103 rotates along impeller 3 from small to large, again from big to small, space when impeller 3 rotates between two blades 302 before this from small to large, produce negative pressure, outside air is sucked from inlet hole 104, after turning over several angle, space between two blades 302 from big to small, air is pumped from air outlet hole 106, go round and begin again.
