Specific embodiment
It please refers to shown in Fig. 1 to Fig. 6, it to be a kind of that show the specific structures of the preferred embodiment of the utility model
Electric inflating pump with exhaust mechanism, including shell 10, inflator pump 20 and pressure relief mechanism 30.
Wherein: the shell 10 has air inlet 11 and inflating port 12, and the inflator pump 20 is accommodated in the inside of shell 10；
In the present embodiment, the shell 10 is made of first shell 101 and second shell 102, and the air inlet 11 is threaded through first
On shell 101, the inflating port 12 and pressure relief opening 31 are threaded through in second shell 102.The inside of the second shell 102 is equipped with
One fixed bit 1021, the inflator pump 20 are mounted on fixed bit 1021.
The shell 10 is equipped with a pressure relief mechanism 30, which includes pressure relief opening 31 and be set on pressure relief opening 31
Relief valve 32, when 10 air pressure inside value of shell is greater than certain atmospheric pressure value, 10 air pressure inside of shell is outside by relief valve 32
Ejection opens pressure relief opening 31 and discharges internal gas outward from pressure relief opening 31.It, on the one hand can be with using the pressure relief mechanism 30 of setting
Guarantee between inflator pump and inflated article will not because pressure is excessive and to be inflated article fill it is quick-fried, on the other hand can benefit
The function of heat dissipation is provided for inflator pump with the pressure relief mechanism of setting, prevents the motor of inflator pump from overheating to damage.
Specifically, the atmospheric pressure value inside the shell 10 is set according to actual needs, the limit value of general air pump
When between 0-3PSI.For example, the atmospheric pressure value limit value of (referring to Fig. 5) inside the shell 10 of the present embodiment is in 3PSI, when not having
When reaching 3PSI, relief valve 32 will not be opened, and gas is then charged in inflated article to inflating port side at this time；(referring to Fig. 6)
When atmospheric pressure value inside shell 10 reaches 3PSI or values above, the air pressure inside of shell 10 can then be ejected gas bleeder valve to incite somebody to action
Air pressure inside shell 10 is discharged into pressure relief opening 31, is no longer inflated to inflated article.
In the present embodiment, the relief valve 32 is made of valve block 321 and valve rod 322, and valve block 321 is arranged in pressure relief opening 31
Outside, the end of valve rod 322 extends to the inside of shell 10.The middle part of the pressure relief opening 31 is equipped with a limit hole 311, institute
Valve rod 322 is stated to extend to inside shell 10 through the limit hole 311.
The end of the valve rod 322 is equipped with one and stops jacking block 323, is being arranged with one on the valve rod 322 being located inside shell 10
Spring 324, the head and the tail both ends of spring 324 are butted on the medial surface of only jacking block 323 and pressure relief opening 31 respectively.By the way that spring 324 is arranged
Rebound dynamics, be adapted the screen resilience of spring 324 with atmospheric pressure value；It is let out using the dynamics and air pressure of the spring 324 with realizing
Pressure mouth 31 is turned on or off, and structure is very simple.It is filled compared to needing to control the electronic of pressure release using control module in the past
Air pump will not lack water-proof function because of air pump, make water capacity control module easy to damage, to the feelings of decompression function failure occur
Condition；Therefore, in use, 30 use of pressure relief mechanism of the present embodiment is more reliable.
It further says, the valve block 321 and valve rod 322 are integrated formed structures.On the lateral surface of the pressure relief opening 31
Equipped with a sealing ring 312, the sealing ring 312 of setting is in order to which there are gap, such setting sides between valve block 321 and pressure relief opening 31
Formula is common technological means, is not repeated herein.
The design focal point of the utility model is: by the way that easy pressure relief mechanism 30 is arranged, when the air pressure inside of shell 10
Greater than setting value when, the air pressure inside of shell 10 then can by relief valve 32 outward eject, thus realize internal gas is outside
Discharge；Compared to the structure for needing to carry out pressure release in the past using control module, can effectively prevent to enter air pump because of water
In so that the case where decompression function fails, ensure that the reliability service of decompression function.
The above descriptions are merely preferred embodiments of the present invention, not makees to the technical scope of the utility model
Any restrictions, therefore any trickle amendment made by the above technical examples according to the technical essence of the present invention, equivalent change
Change and modify, is still within the scope of the technical solutions of the present invention.
