Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1 —4. A water volume control structure of a water gun of a car washing machine, comprising a car washing water gun, wherein the car washing water gun comprises a gripping portion 100, a water spraying portion 200 and a battery portion 300, wherein the gripping portion 100 is used for holding by an operator, and a battery portion 300 is provided at the bottom of the gripping portion 100, and the battery portion 300 provides electric energy for the water gun, and a water spraying portion 200 for spraying water is provided at the upper portion of the gripping portion 100, and in addition, a water pump is also provided in the gripping portion 100, and a water delivery channel 201 is provided in the water spraying portion 200, and a water outlet 207 of the water pump is connected to the water delivery channel 201 through a connecting waterway 202, so that external water can be pumped into the water delivery channel through the water pump;

[0020] In addition, a sealing platform 203 is fixedly connected to the rear of the connecting water channel 202 in the water delivery channel 201, and a control column 204 is slidably connected to the sealing platform 203. An electrical chamber 205 is arranged behind the sealing platform 203 in the water spraying part 200, and a driving mechanism is arranged in the electrical chamber 205. The moving part of the driving mechanism is fixedly connected to the control column 204, so that the control column 204 can be driven to move forward and backward through the driving mechanism. Furthermore, a ring platform 206 is fixedly connected to the front of the connecting water channel 202 in the water delivery channel, and the ring platform 206 is slidably connected to the sealing platform 203. The platform 206 is provided with a water outlet 207, and the end of the control column 204 is fixedly connected with a conical water blocking platform 208. When the control column 204 moves forward and backward, it can drive the conical water blocking platform 208 to move forward and backward. The amount of water output is adjusted by the blocking size of the water outlet 207 by the conical water blocking platform 208. When the water output is small, the injection intensity is large, and when the water output is large, the injection intensity is small. Therefore, when washing a car, it can be adjusted according to actual needs, saving water resources and improving the use effect of the car washing water gun.

[0021] Furthermore, the driving mechanism includes a motor 209, a fixed sleeve 210, a moving sleeve 211 and a lead screw 212. The fixed sleeve 210 is fixedly connected in the electrical cavity 205. A moving groove 213 is provided on the inner wall of the fixed sleeve 210. A moving bar 214 is fixedly connected to the matching moving groove 213 on the moving sleeve 211. The moving bar 214 is slidably connected in the moving groove 213, so that the moving sleeve 211 can slide linearly in the fixed sleeve 210. A chamber 215 is also provided inside the moving sleeve 211. The tail end of the moving sleeve 211 is threadedly connected to the lead screw 212. The lead screw 212 is located at In the chamber 215, one end of the lead screw 212 is also fixedly connected to the connecting shaft 216, and the electric chamber 205 is fixedly connected to the motor 209, the motor 209 is connected to the connecting shaft 216, and one end of the moving sleeve 211 is fixedly connected to the control column 204, so that the motor 209 can drive the lead screw 212 to rotate. When the lead screw 212 rotates, the moving sleeve 211 can move linearly in the fixed sleeve 210, so that the moving sleeve 211 drives the control column 204 and the conical water blocking platform 208 thereon to move, so as to realize the control of the blocking size of the water outlet 207 by the conical water blocking platform 208;

[0022] In addition, a ring hole is provided on the sealing platform 203, and the control column 204 passes through the ring hole. A plurality of sealing rings are fixedly connected to the inner wall of the ring hole. The sealing rings are used to achieve a sealing effect between the control column 204 and the sealing platform 203, thereby preventing water from intruding into the electrical cavity 205, affecting the normal operation of the internal motor 209, and reducing the water spraying force. In addition, a drain port 217 is provided at the bottom of the water spraying part 200 and connected to the electrical cavity 205. When the sealing effect is lost, water can enter the electrical cavity 205 and be discharged through the drain port 217, thereby preventing the electrical cavity 205 from being damaged. Water accumulates inside, causing electrical damage, and can also warn users that the water gun is damaged. At the same time, a control module 218 based on a single-chip microcomputer is fixedly connected in the electrical cavity 205, and a control button 219 is fixedly connected to the water spray part 200. The control button 219 and the motor 209 are both electrically connected to the control module 218. In this way, a signal can be sent to the control module 218 through the control button 219, and then the control module 218 controls the motor 209 to work according to the signal to adjust the water spray volume. The control module 218 here can use a combination module of an Arduino Uno microcontroller combined with a DRV8825 motor 209 controller, and the motor 209 uses a stepper motor 209.
