According to one embodiment of the present invention, referring to fig. 1 to 6, a high heat dissipation type inflator comprises a housing, a motor, and an impeller 4000. Wherein, the casing has air exhaust portion 1100, aerifys portion 3000 and station 2100, and the casing is inside to be equipped with the cavity, and motor and impeller 4000 are installed respectively in station 2100 and cavity. The impeller 4000 may comprise a substrate 4100 drivingly connected to the motor, and a first blade 4200 and a second blade 4300 disposed on opposite ends of the substrate 4100, with the first blade 4200 disposed toward the pumping section 1100 and the second blade 4300 disposed toward the station 2100.

When the motor drives the impeller 4000 to rotate, the first blade 4200 pumps external gas to the inflating part 3000 through the pumping part 1100, the second blade 4300 pumps external gas to the inflating part 3000 through the station 2100, and two gas flows are converged at the inflating part 3000 and are synchronously discharged from the inflating part 3000.

In this embodiment, by disposing the first blade 4200 and the second blade 4300 on the opposite end surfaces of the substrate 4100, respectively, and disposing the first blade 4200 facing the pumping section 1100 and the second blade 4300 facing the station 2100, when the high heat dissipation type pressurization inflator is operated, external gas can be simultaneously pumped to the pumping section 3000 through the pumping section 1100 and the station 2100. Compared with the prior art that the external gas can be extracted to the inflation portion 3000 through only one position, in the embodiment, the first blade 4200 and the second blade 4300 are respectively arranged on the two opposite end faces of the substrate 4100, so that during the rotation of the motor driving the impeller 4000, the first blade 4200 and the second blade 4300 can synchronously extract the external gas to the inflation portion 3000 through the gas extraction portion 1100 and the station 2100, and two gas flows are converged at the inflation portion 3000 and synchronously discharged from the inflation portion 3000 to inflate the device to be inflated, so that the pressure of the gas discharged through the inflation portion 3000 can be greatly increased, and the inflation efficiency is improved. In addition, when the second blade 4300 extracts outside gas to the inflation portion 3000 through the station 2100, with the help of the flow of the gas, the heat generated by the motor in the operation process can be taken away, the heat dissipation effect is improved, the motor can be ensured to operate at a proper temperature, and the service life and the service performance of the inflator pump are improved.

Preferably, referring to fig. 1 and 5, the suction portion 1100 and the station 2100 are disposed on the upper and lower end surfaces of the housing, respectively, and the inflation portion 3000 is disposed on the side edge of the housing. Since the first blade 4200 and the second blade 4300 are disposed on opposite end surfaces of the substrate 4100 and respectively face the pumping section 1100 and the station 2100, the pumping section 1100 and the station 2100 are disposed on upper and lower end surfaces of the casing and can face the impeller 4000, so that the first blade 4200 and the second blade 4300 can simultaneously pump external gas when the impeller 4000 rotates, thereby improving the charging efficiency. Meanwhile, when the impeller 4000 is driven by the motor to rotate, the first blade 4200 and the second blade 4300 of the impeller drive the extracted external gas to rotate, and the inflatable portion 3000 is arranged at the side edge of the casing, which is more beneficial for the gas to be discharged from the inflatable portion 3000 during the rotation process.

In one embodiment, referring to fig. 4 and 5, a substrate 4100 separates the cavity into a first chamber 1300 and a second chamber 2300. At this time, the first chamber 1300 is communicated with the evacuation section 1100, the second chamber 2300 is communicated with the station 2100, and a gap is reserved between the side edge of the substrate 4100 and the inner sidewall of the housing, which allows the first chamber 1300 and the second chamber 2300 to be communicated with each other.

In this embodiment, a gap is reserved between the side edge of the substrate 4100 and the inner sidewall of the housing, so that the impeller 4000 can rotate more smoothly in the cavity, and does not collide with the inner sidewall, thereby prolonging the service life of the impeller. Moreover, the first chamber 1300 and the second chamber 2300 are communicated, so that the efficiency of extracting external air when the impeller 4000 rotates can be improved, and the flow rate of the air is increased; on the other hand, the circulation of air in the station 2100 communicated with the second chamber 2300 can be enhanced, and the heat dissipation effect on the motor is improved.

It should be noted that, in the embodiment, the substrate 4100 isolates the first blade 4200 from the second blade 4300, that is, the first blade 4200 and the second blade 4300 extract gas in opposite directions, so that the first blade 4200 is effectively prevented from synchronously extracting the gas entering the interior of the inflator through the station 2100 in the process of extracting the gas toward the pumping section 1100; likewise, the second blade 4300 does not simultaneously extract gas entering the interior of the inflator through the extraction section 1100 during the extraction of gas toward the station 2100. That is, the first blade 4200 and the second blade 4300 operate independently of each other and do not interfere with each other during rotation, so that the two air flows do not interfere with each other and interfere with the normal flow rate, so that the air flows can synchronously enter the interior of the inflator through the pumping section 1100 and the station 2100 and synchronously exit the inflator 3000.

As a preferred embodiment, the first blades 4200 and the second blades 4300 are equal in number and are each spaced around the peripheral side of the substrate 4100. In this embodiment, the number of the first blades 4200 and the second blades 4300 may be nine, and the first blades and the second blades 4300 are arranged in a one-to-one correspondence. However, in actual production, the number of the active carbon particles is not limited to the above number, and the active carbon particles can be flexibly arranged according to actual situations, and are all within the protection scope of the patent.

Further preferably, referring to fig. 3 and 5, the first blade 4200 and the second blade 4300 conform in profile. The first blade 4200 and the second blade 4300 are separated from one end of the substrate 4100, and a first drainage slope 4210 and a second drainage slope 4310 are respectively disposed on one side of the substrate 4100 facing the edge.

Specifically, during rotation of the impeller 4000, the first flow ramp 4210 may direct gas within the first chamber 1300 to the edge of the first chamber 1300 and to the plenum 3000. Correspondingly, the second slope guiding surface 4310 can guide the gas in the second chamber 2300 to the edge of the second chamber 2300 and deliver the gas to the plenum 3000, and the two gas flows converge at the plenum 3000 and are simultaneously discharged from the plenum 3000.

The arrangement of the first slope 4210 and the second slope 4310 helps to guide the gas in the first chamber 1300 near the pumping section 1100 and the gas in the second chamber 2300 near the station 2100 to the edge region, so that more gas can flow to the inflation section 3000 disposed at the side edge of the housing, thereby increasing the pressure of the gas discharged from the inflation section 3000 and improving the inflation efficiency.

In actual production, the drainage slope surface can also be set to be a cambered surface, the specific structural shape of the drainage slope surface is not limited herein, and the drainage slope surface can be set according to actual requirements and is within the protection scope of the utility model.

On this basis, referring to fig. 3 and 5, the end wall of the first chamber 1300 in correspondence with the area of the plurality of first flow directing ramps 4210 forms a first mating annular rim 1400 parallel to the first flow directing ramps 4210. Correspondingly, the end wall of the second chamber 2300 forms a second mating annular edge 2400 parallel to the second drainage ramp 4310 in correspondence with the area of the plurality of second drainage ramps 4310.

At this moment, the first drainage slope 4210 and the first matching annular edge 1400 parallel thereto form a channel for gas circulation, thereby improving the drainage effect of the first drainage slope 4210. Correspondingly, the second drainage slope 4310 and the second matching annular edge 2400 parallel to the second drainage slope 4310 further improve the drainage effect of the second drainage slope 4310, so that the utilization rate of gas in the cavity is improved, and the inflation efficiency is improved.

In one embodiment, referring to fig. 1 and 5, the housing can be a disk configuration with the extraction section 1100 opening at the center of the upper end face of the housing and correspondingly, the station 2100 opening at the center of the lower end face of the housing. At this time, the inflator 3000 extends in a tangential direction of the case side edge.

In this embodiment, the casing is set to a disc structure, which is more favorable for the impeller 4000 to drive the gas in the cavity to rotate, and in addition, the air exhaust part 1100 is arranged at the center of the upper end surface of the casing, and the station 2100 is arranged at the center of the lower end surface of the casing, so that the impeller 4000 can drive all the gas in the cavity to rotate as much as possible, and the efficiency of extracting the external gas is improved. Because the impeller 4000 drives the gas in the cavity to do approximate circular motion, the gas charging part 3000 extends along the tangential direction of the side edge of the shell to facilitate the discharge of the gas, and the gas charging efficiency is improved.

In actual production, the efficiency of the impeller 4000 for extracting the external air can be improved by only arranging the air extracting part 1100 and the station 2100 in the region corresponding to the center of the impeller 4000, and at this time, the impeller 4000 can be arranged in the center region of the casing or eccentrically.

In one embodiment, referring to fig. 1, 2 and 5, in order to facilitate quick assembly, the housing may preferably be a split design, which may specifically include a first housing 1000 and a second housing 2000 that are engaged with each other. Wherein, the air extracting portion 1100 is opened in the first casing 1000, and preferably integrally formed with the first casing 1000; and station 2100 is open to second housing 2000 and is preferably integrally formed with second housing 2000. Further, the inflator 3000 may be preferably provided to a side edge which is formed by the first case 1000 and the second case 2000 together. And the side edges of the first casing 1000 and the second casing 2000 are respectively provided with a plurality of corresponding first mounting parts 1200 and second mounting parts 2200, and each corresponding first mounting part 1200 and second mounting part 2200 are oppositely matched and fixed by a locking part.

The casing adopts the components of a whole that can function independently to set up and is more favorable to the dismouting and the maintenance of this high heat dissipation type pressurization pump, if when needing to change impeller 4000, demolish the retaining member and can carry out impeller 4000's change. And the gas filling part 3000 is disposed at the side edge formed by the first casing 1000 and the second casing 2000 together, which is beneficial for the gas in the first chamber 1300 and the second chamber 2300 to be discharged from the gas filling part 3000 at the same time, and preferably, the gas filling part 3000 is symmetrically distributed along the embedded plane of the first casing 1000 and the second casing 2000.

In actual production, the locking member may be a bolt, a screw, etc., and will not be described herein.

In one embodiment, referring to fig. 5 and 6, station 2100 may be a hollow sleeve configuration, which may preferably be cylindrical, but is not so limited. Inside the station 2100, and at the connection with the housing, i.e., the second housing 2000, there is provided a motor mounting portion 2110, and the motor is mounted to the motor mounting portion 2110. In addition, a diversion hole 2113 communicated with the cavity and the station 2100 is arranged on the motor mounting part 2110. Through this water conservancy diversion hole 2113 can make outside gas circulate to the cavity through station 2100 to be extracted to inflatable portion 3000, when increasing inflatable portion 3000 exhaust gas pressure, can also dispel the heat to the motor, make the motor normal operating. It should be noted that, in this embodiment, an annular gap is formed between the side wall of the motor and the inner wall of the station 2100, and the gas enters the cavity through the annular gap and the flow guide holes 2113 during the flowing process. Therefore, the gas can always adhere to the side wall of the motor to flow so as to achieve the effect of fully radiating the motor.

Specifically, the motor mounting portion 2110 may include a ring 2111 and a plurality of support arms 2112 spaced apart along a circumference of the ring 2111, the support arms 2112 may fix the ring 2111 to the lower end surface of the housing, and a diversion hole 2113 is formed between every two adjacent support arms 2112.

Wherein, the motor is fixed on the ring plate 2111, and the driving shaft of the motor extends to the inside of the cavity through the ring plate 2111 for butting the substrate 4100 of the impeller 4000.

It should be noted that, in actual production, the opening of the ring plate 2111 may be set slightly larger, which is helpful to increase the air flow rate and improve the inflation efficiency, and the heat dissipation effect is better.

It should be noted that the above embodiments can be freely combined as necessary. The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
