[0031] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand this utility model and implement it. However, the embodiments are not intended to limit this utility model. In this embodiment, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this utility model.

[0032] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to and integrated with the other element, or there may be an intervening element present. The terms "mounted," "one end," "the other end," and similar expressions used in this invention are for illustrative purposes only.

[0033] This embodiment provides a spray gun controller, such as Figures 1-8 As shown, it includes an air outlet 1, a throttle motor 2, an air inlet pipe 3, and an air outlet pipe 4. The air inlet pipe 3 is connected to the input end of the air outlet 1, and the output end of the throttle motor 2 is connected to the air outlet pipe 4. The throttle motor 2 is a throttle motor 2 equipped with a throttle valve.

[0034] The air outlet 1 is provided with an air passage 11 and a mounting cavity 12. The air passage 11 is connected to the mounting cavity 12. The throttle motor 2 is embedded in the mounting cavity 12 and the input end of the throttle motor 2 extends into the air passage 1. The distance L2 between the axis of the air passage 11 and the valve core 21 of the throttle motor is less than the width of the air passage 11.

[0035] By embedding the throttling motor 2 in the mounting cavity 12, the throttling motor 2 is housed within the air outlet 1, reducing the space occupied by the throttling motor 2 in the spray gun controller. This reduces the overall size of the spray gun controller. At the same time, the input end of the throttling motor 2 extends into the air passage 1, and the length between the axis of the air passage 11 and the throttling motor valve core 21 is set, shortening the distance between the air passage 11 and the throttling motor valve core 21, reducing the impact on the output efficiency and air pressure of the airflow.

[0036] A first vent hole 13 is provided on the wall of the mounting cavity 12; the input end of the throttle motor 1 is a second vent hole 22 on the wall of the throttle motor 2, and the air passage 11, the first vent hole 13, and the second vent hole 22 are connected. The first vent hole 13 and the second vent hole 22 are provided to allow airflow in the air passage 11 to enter the throttle motor 2.

[0037] The second vent hole 22 is located outside the throttling motor valve core 21, and the first vent hole 13 is arranged opposite to the second vent hole 22. Meanwhile, the second vent hole 22 is arranged outside the throttling motor valve core 21, so that the air flow flowing into the throttling motor 2 can quickly flow into the throttling motor valve core 21, shortening the flow distance of the air in the throttling motor 2. Meanwhile, the first vent hole 13 is arranged opposite to the second vent hole 22, improving the efficiency of the air flow into the throttling motor 2.

[0038] Referring to Figure 5 , Figure 8 As shown in the figure, the second vent hole 22 is arranged through the throttling motor 2. By arranging the second vent hole 22 through the throttling motor 2, the air flow entering the mounting cavity 12 can enter the throttling motor 2 from different positions, improving the efficiency of the air flow into the throttling motor 2.

[0039] In a preferred embodiment, the throttling motor 2 is shape-matched with the mounting cavity 12. In this way, the fitting degree between the throttling motor 2 and the mounting cavity 12 is high, further reducing the occupied space of the throttling motor 2 and the air exhaust 1.

[0040] In a preferred embodiment, the opening size of the first vent hole 13 is larger than the opening size of the second vent hole 22. In this way, the efficiency of the air flow into the throttling motor 2 is improved.

[0041] In a preferred embodiment, the mounting cavity 12 is provided with a plurality of mounting cavities 12, and the plurality of mounting cavities 12 are arranged at intervals along the height direction of the air exhaust 1. Each mounting cavity 12 is embedded with a throttling motor 2.

[0042] The torch controller further comprises an electromagnetic valve 5, an air outlet elbow 6 and an air inlet elbow 7. The air inlet pipe 3 is connected to the input end of the air exhaust 1 through the electromagnetic valve 5. The electromagnetic valve 5 is arranged to control the air flow into the air exhaust 1. The output end of the electromagnetic valve 5 is connected to the air outlet elbow 6, and the input end of the air exhaust 1 is connected to the air inlet elbow 7. The air outlet elbow 6 is arranged opposite to the air inlet elbow 7. In a preferred embodiment, the air outlet elbow 6 and the air inlet elbow 7 are arranged opposite to each other in a plane, so as to shorten the distance between the air outlet elbow 6 and the air inlet elbow 7, and shorten the flow distance of the air flow from the electromagnetic valve 5 into the air exhaust 1.

[0043] In an embodiment, the torch controller is installed in a housing 8 for use. The housing 8 is provided with a control chip 9. The electromagnetic valve 5 and the throttling motor 2 are signal-connected to the control chip 9. In use, the control chip 9 controls the on-off of the electromagnetic valve 5, thereby controlling the air flow into the air exhaust 1. The control chip 9 controls the opening degree of the valve core of the throttling motor 2, thereby controlling the air outlet amount of the throttling motor 2. The control chip 9 controls the electromagnetic valve 5 and the throttling motor 2, which is a prior art and will not be described here.
