[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figures 1-4 As shown, the intelligent constant pressure blower includes a housing 1, on which a fan 2, a drive mechanism 3, a pressure detector 4, and a controller 5 are mounted. The housing 1 has a flow guide cavity 101 and an air outlet 102. The flow guide cavity 101 is connected to the outside through the air outlet 102. The pressure detector 4 is located on one side of the air outlet 102 for detecting pressure. The fan 2 is housed in the flow guide cavity 101 and driven by the drive mechanism 3. When the real-time pressure detected by the pressure detector 4 deviates from the preset pressure, the drive mechanism 3 is controlled to increase or decrease the speed of the fan 2. The pressure detector 4 can be, but is not limited to, a pressure sensor, and the controller 5 is an existing circuit board.

[0024] When using this intelligent constant pressure blower to inflate inflatable amusement facilities, the steps are as follows: First, based on the required surface hardness of the inflatable amusement facility, a preset pressure is set (this preset pressure is the target air pressure required by the inflatable amusement facility). Then, the intelligent constant pressure blower blows air, and at the same time, the pressure detector 4 detects the pressure on one side of the air outlet 102 in real time (this pressure is defined as the real-time pressure). When the real-time pressure detected by the pressure detector 4 is higher than the preset pressure, the drive mechanism 3 is controlled to reduce the speed of the impeller 2 to make the real-time pressure consistent with the preset pressure. When the real-time pressure detected by the pressure detector 4 is lower than the preset pressure, the drive mechanism 3 is controlled to increase the speed of the impeller 2 to make the real-time pressure consistent with the preset pressure.

[0025] It should be noted that the intelligent constant pressure blower is connected to the inflatable amusement facility through the air outlet 102 for inflation, and the pressure at the air outlet 102 is the internal air pressure of the inflatable amusement facility.

[0026] In summary, this embodiment provides an intelligent constant pressure blower to solve the problem that existing blowers continuously blow air but lack a structure for detecting the air pressure inside inflatable amusement facilities, resulting in excessively high or low air pressure inside the inflatable amusement facilities. This is mainly achieved by configuring a pressure detector 4 on one side of the air outlet 102 and configuring the drive mechanism 3 to control the speed of the impeller 2 to increase or decrease when the real-time pressure detected by the pressure detector 4 deviates from the preset pressure, so that the real-time pressure on the side of the air outlet 102 is consistent with the preset pressure, thus avoiding excessively high or low air pressure inside the inflatable amusement facility.
