Referring to fig. 1 to 5, according to an embodiment of the present utility model, there is provided an inflator comprising a housing 10, a cylinder 20, and a heat radiation fan 30, the housing 10 being provided with an extraction opening 11; a heat dissipation air duct 12 is formed inside the housing 10; the cylinder 20 is arranged in the shell 10, and the air suction port 21 of the cylinder 20 is communicated with the air suction port 11; the heat radiation fan 30 is arranged in the heat radiation air duct 12; the air intake end 12a of the heat dissipation air duct 12 communicates with the air extraction opening 11.

Referring to fig. 1 to 5, the inflator further includes a solenoid valve 40, the solenoid valve 40 is installed at the position of the air inlet end 12a of the heat dissipation air duct 12, and the solenoid valve 40 is used for controlling the communication and blocking of the air inlet end 12a of the heat dissipation air duct 12 and the air extraction opening 11. The electromagnetic valve 40 controls the communication and the separation of the heat dissipation air duct 12 and the air extraction opening 11, so as to firstly control whether the air flow in the heat dissipation air duct enters to achieve the heat dissipation effect, and also control the air suction pressure of the air extraction opening 11, namely, whether the air cylinder is used for air suction or whether the air cylinder and the heat dissipation fan are used for air suction together.

Preferably, a transition cavity 13 is formed inside the casing 10, and the transition cavity 13 is communicated with the air extraction opening 11; the transition chamber 13 communicates with the intake end 12a of the cooling air duct 12 through the vent hole 14, the solenoid valve 40 is provided at the vent hole 14, and the solenoid valve 40 controls the communication and blocking of the intake end 12a of the cooling air duct 12 with the extraction opening 11 by opening or closing the vent hole 14. The transition cavity 13 firstly works together with the electromagnetic valve 40 to control the communication and the separation of the air inlet end 12a of the heat dissipation air duct 12 and the air extraction opening 11; the transition cavity 13 is used for buffering the air, so that the air is prevented from being unevenly distributed due to the fact that negative pressure on one side is large after the air enters. The transition chamber 13 enables one-thing multi-use with unexpected technical effects.

Preferably, in order to ensure that the suction pressure of the cylinder 20 is not affected, a suction chamber 15 is formed inside the casing 10, the suction chamber 15 being in communication with the transition chamber 13; the suction port 21 of the cylinder 20 is located in the suction chamber 15, see fig. 3 and 4.

To further ensure the airtightness of the suction chamber, in this embodiment, as shown in connection with fig. 2 and 3, the inflator further includes a cylinder seal 50, the cylinder seal 50 being disposed inside the housing 10, and the suction chamber 15 being formed between the cylinder seal 50 and the shell plate of the housing 10. Referring to fig. 2 and 5, the structural shape of the cylinder seal 50 is adapted to the cylinder 20, while the structural shape of the cylinder seal 50 is matched to the shell plate of the housing to achieve a sealing effect.

The electromagnetic valve 40 has a first state of controlling the air inlet end 12a of the cooling air duct 12 to communicate with the air extraction opening 11, and the electromagnetic valve 40 has a second state of controlling the air inlet end 12a of the cooling air duct 12 to be blocked from the air extraction opening 11; the inflator further includes a controller electrically connected to the solenoid valve 40 for receiving the command information and controlling the solenoid valve 40 to switch between the first state and the second state.

This scheme has 2 inhalation modes: a normal inhalation mode, a high pressure inhalation mode; after receiving instruction information of a user, the controller selects any one of the two modes to control. When the normal inhalation mode is selected, the solenoid valve 40 switches to the first state and activates the inflator with a majority of the flow as shown in FIG. 2 (flow direction see arrow) and a minority of the flow as shown in FIG. 3 (flow direction see arrow). At this time, the main source of suction is the rotation of the heat dissipation fan. The conventional inhalation mode is generally used in the case where the total amount of inhalation is large and the inhalation pressure is small. When the high pressure suction mode is selected, the solenoid valve 40 switches to the second state, activating the inflator and the flow direction is shown in FIG. 3. At this time, the main source of suction is the self-suction of the cylinder, the maximum suction pressure can reach 10MPa, and the pressure of the vacuum pump is far above the pressure of the vacuum pump on the market. The high pressure suction mode is generally used when the total amount of suction is small and the suction pressure is large.

To enhance the heat dissipation effect, in the present embodiment, at least a part of the structure of the cylinder 20 is located in the heat dissipation duct 12. The air outlet end 12b of the heat dissipation air duct 12 is disposed on the housing 10, and the heat dissipation fan 30 drives the air flow to flow from the air inlet end 12a to the air outlet end 12b of the heat dissipation air duct 12.

According to an embodiment of the present utility model, there is provided a control method of an inflator, referring to fig. 6, the inflator is an inflator of the above embodiment, and the control method includes:

step S10: receiving instruction information;

step S20: and controlling the electromagnetic valve according to the instruction information.

The electromagnetic valve can control the suction pressure of the suction opening 11 by controlling the communication and the separation of the heat dissipation air duct and the suction opening of the air pump, and selects whether the air cylinder is used for suction or the air cylinder and the heat dissipation fan are used for suction together. The control method can change the air suction pressure of the inflator pump according to the selection of a user or the actual requirement, and intelligent air suction is realized.

Preferably, the instruction information may be a pumping mode preset in advance, where the pumping mode includes pumping time, pressure parameter, interval time, and the like of the inflator pump. In the present embodiment, the step of controlling the solenoid valve (step S20) includes:

if the instruction information is in the first air extraction mode, controlling the electromagnetic valve to switch to a first state;

and if the instruction information is in the second air extraction mode, controlling the electromagnetic valve to switch to a second state.

The first pumping mode is a conventional pumping mode, the total pumping amount is larger, but the pumping pressure is smaller, and the specific setting can be selected according to the power of the inflator pump. The second air suction mode is a high-pressure air suction mode, the total air suction amount is smaller, the air suction pressure is larger, and the specific setting can be selected according to the power of the inflator pump.

The instruction information can also be a pressure value, for example, a pressure input option is provided on a display screen or a key of the inflator pump, and if the pressure value is directly input by a user, the control method can also judge according to the pressure value and select the optimal air pumping mode. Preferably, the instruction information includes a pressure value; the step of controlling the solenoid valve (step S20) according to the instruction information includes the steps of:

judging whether the pressure value in the instruction information is larger than a preset value or not;

if yes, the electromagnetic valve is controlled to be switched to a second state;

if not, the solenoid valve is controlled to switch to the first state.

When the pumping pressure value required by the user is large (namely, larger than a preset value), the inflator pump is controlled to be switched to the second state. When the pumping pressure value required by the user is smaller (namely smaller than a preset value), the inflator pump is controlled to be switched to the first state. The control method of the embodiment can select the optimal air extraction mode according to the pressure value, and is more intelligent.
