[0004] Therefore, it is urgent to provide a car washing water gun system and a car washing machine to solve the problems in the prior art to a certain extent. Utility Model Content
[0005] The purpose of the utility model is to provide a car washing water gun system and a car washing machine, so as to solve the problem of optimizing the structure of the car washing water gun system, improving the service life of the car washing water gun system, and reducing the problem of bursting of the water supply pump during use.
[0006] The utility model provides a car washing water gun system, comprising a water supply mechanism, a pump body, a pressure relief mechanism and a water spray gun; the water supply mechanism is connected to the water inlet end of the pump body, and the first water outlet end of the pump body is connected to the water spray gun; the pressure relief mechanism comprises a pressure relief component, a blocking component and a balancing pipe, the second water outlet end of the pump body is connected to the water inlet of the pressure relief component, the blocking component is arranged in the pressure relief component and can block or open the water inlet of the pressure relief component; the water outlet of the pressure relief component is connected to one end of the balancing pipe, and the other end is connected to the pressure relief end of the pump body.
[0007] The water supply mechanism includes a water tank, a water supply pipe and a control valve. The water tank is connected to the pump body through the water supply pipe. The control valve is arranged on the water supply pipe and can control the on and off of the water supply pipe.
[0008] Specifically, the car washing water gun system provided by the present invention further includes a control component, which is connected to the pump body and can control the start and stop of the pump body.
[0009] Furthermore, the water supply mechanism further includes a liquid level detection component, which is disposed at the bottom of the water tank, and the liquid level detection component is communicatively connected to the control component, and the control component is communicatively connected to the control valve.
[0010] Furthermore, the car washing water gun system provided by the present invention also includes a flow rate detection component, which is arranged on the water supply pipe and is communicatively connected to the control component for detecting the water flow rate passing through the water supply pipe.
[0011] Among them, the pressure relief component includes a main body, a movable part and an elastic part, one end of the main body is the water inlet, and the water inlet is connected to the second water outlet end of the pump body; the elastic part is arranged in the main body, the movable part is connected to the elastic part, and the movable part can block or open the water inlet.
[0012] Specifically, the car washing water gun system provided by the present invention also includes a normally closed micro switch, which is communicatively connected to the control component; a contact part is connected to the movable part, and the contact part can move with the movable part to contact or move away from the normally closed micro switch.
[0013] Furthermore, the control valve is a normally closed solenoid valve, and the control component is communicatively connected to the control valve.
[0014] Furthermore, the pump body is a high-pressure plunger pump, and the control component is communicatively connected to the high-pressure plunger pump.
[0015] Compared with the existing technology, the car washing water gun system provided by the utility model has the following advantages:
[0016] The car washing water gun system provided by the utility model includes a water supply mechanism, a pump body, a pressure relief mechanism and a water spray gun; the water supply mechanism is connected with the water inlet end of the pump body, and the first water outlet end of the pump body is connected with the water spray gun; the pressure relief mechanism includes a pressure relief component, a blocking component and a balancing pipe, the second water outlet end of the pump body is connected with the water inlet of the pressure relief component, the blocking component is arranged in the pressure relief component and can block or open the water inlet of the pressure relief component; the water outlet of the pressure relief component is connected with one end of the balancing pipe, and the other end is connected with the pressure relief end of the pump body.
[0017] From this analysis, it can be seen that the water supply mechanism can provide water to the pump body, thereby connecting the first water outlet of the pump body to the water spray gun, thereby achieving the purpose of supplying water to the water spray gun. Because the second water outlet of the pump body in this application is connected to the water inlet of the pressure relief component, and the blocking member is disposed within the pressure relief component and can block or open the water inlet of the pressure relief component, when the water spray gun is turned on and high-pressure water is sprayed from the water spray gun, the pressure in the pump body is insufficient to push open the blocking member, thereby achieving the function of the water spray gun.
[0018] When the water gun is closed, the pressure in the pump body increases and cannot be sprayed out by the water gun, so that the accumulated pressure can push open the blocking component. Since one end of the balancing pipe in the present application is connected to the water outlet of the pressure relief component and the other end is connected to the pressure relief end of the pump body, the water entering the pressure relief component can be discharged by the balancing pipe, thereby realizing the pressure dumping of the pump body, thereby avoiding to a certain extent the problem of pump body rupture and damage caused by excessive pressure in the pump body due to the closure of the water gun.
[0019] In addition, the utility model also provides a car washing machine, which includes the above-mentioned car washing water gun system.
[0020] In the car wash water gun system provided in this application, when the water gun stops, the pressure in the pump body can be released, thereby ensuring the stable operation of the pump body, avoiding the problem of rupture and damage to the pump body, and improving the service life of the car wash water gun system, thereby improving the service life of the entire car washing machine.

[0033] like Figure 1 As shown, the utility model provides a car washing water gun system, including a water supply mechanism, a pump body 5, a pressure relief mechanism and a water spray gun 6; the water supply mechanism is connected to the water inlet end of the pump body 5, and the first water outlet end of the pump body 5 is connected to the water spray gun 6; the pressure relief mechanism includes a pressure relief component 7, a blocking component and a balancing pipe 9, the second water outlet end of the pump body 5 is connected to the water inlet of the pressure relief component 7, the blocking component is arranged in the pressure relief component 7, and can block or open the water inlet of the pressure relief component 7; the water outlet of the pressure relief component 7 is connected to one end of the balancing pipe 9, and the other end is connected to the pressure relief end of the pump body 5.
[0034] Compared with the existing technology, the car washing water gun system provided by the utility model has the following advantages:
[0035] The car wash water gun system provided by the present invention can provide a water source for the pump body 5 through a water supply mechanism, thereby connecting the first water outlet of the pump body 5 to the water gun 6, thereby achieving the purpose of supplying water to the water gun 6. Since the second water outlet of the pump body 5 is connected to the water inlet of the pressure relief component 7 in the present application, and the blocking component is disposed within the pressure relief component 7 and can block or open the water inlet of the pressure relief component 7, when the water gun 6 is turned on and high-pressure water is sprayed from the water gun 6, the pressure in the pump body 5 is insufficient to push open the blocking component, thereby achieving the function of the water gun 6.
[0036] When the water gun 6 is closed, the pressure in the pump body 5 increases and cannot be sprayed out by the water gun 6, so that the accumulated pressure can push open the blocking component. Since one end of the balancing pipe 9 in the present application is connected to the water outlet of the pressure relief component 7, and the other end is connected to the pressure relief end of the pump body 5, the water entering the pressure relief component 7 can be discharged by the balancing pipe 9, thereby realizing the pressure dumping of the pump body 5, thereby avoiding to a certain extent the problem of rupture and damage of the pump body 5 caused by excessive pressure in the pump body 5 due to the closure of the water gun 6.
[0037] Alternatively, as Figure 1 As shown, the water supply mechanism in this application includes a water tank 1, a water supply pipe 3 and a control valve 2. The water tank 1 is connected to the pump body 5 through the water supply pipe 3. The control valve 2 is arranged on the water supply pipe 3 and can control the on and off of the water supply pipe 3.
[0038] The control valve 2 in the present application can be a manual valve. When it is needed, the valve is manually opened to connect the water tank 1 with the pump body 5 and complete the water supply. When the car washing operation is completed, the control valve 2 can be manually closed to isolate the water in the water tank 1 from the pump body 5.
[0039] Alternatively, as Figure 1 As shown, the car washing water gun system provided by the present invention further includes a control component 10 , which is connected to the pump body 5 and can control the start and stop of the pump body 5 .
[0040] The control component 10 in the present application is a commonly used PCB or other integrated control board, which can control the start and stop of the pump body 5 through lines or signals. Correspondingly, the above-mentioned control valve 2 in the present application can also adopt a solenoid valve, and the solenoid valve is opened or closed through the control component 10, thereby realizing the passage or stop of the water source and improving the operating efficiency of the overall structure.
[0041] It can be understood that the control valve 2 in the present application is a normally closed solenoid valve, so that the water source in the water tank 1 can be always blocked.
[0042] Alternatively, as Figure 1 As shown, the water supply mechanism provided in this application also includes a liquid level detection component 101, which is arranged at the bottom of the water tank 1, and the liquid level detection component 101 is communicatively connected to the control component 10, and the control component 10 is communicatively connected to the control valve 2.
[0043] Since the water level in the water tank 1 continues to decrease during use, when the water flows out, if the pump body 5 continues to operate, the pump body 5 is actually in a dry-running state, which is prone to damage or malfunction. Therefore, the present application adds a liquid level detection component 101 at the bottom of the water tank 1. When the liquid in the water tank 1 is lower than the liquid level detection component 101, the liquid level detection component 101 will send a water shortage signal to the control component 10, so that the pump body 5 can be closed through the control component 10 to prevent the pump body 5 from running dry and causing malfunction or damage.
[0044] Furthermore, if Figure 1 As shown, the car washing water gun system provided by the present invention also includes a flow rate detection component 4, which is arranged on the water supply pipe 3, and the flow rate detection component 4 is communicatively connected with the control component 10 for detecting the water flow rate passing through the water supply pipe 3.
[0045] It should be noted that the flow velocity detection component 4 described above in this application can, based on the passage of water, drive the turbine mechanism inside the flow velocity detection component 4 to start operating, converting the work done by the water flow into a measurable pulse electrical signal, and transmitting this signal to the control component 10, thereby detecting the water flow velocity. When the control component 10 receives the pulse signal, it indicates that there is normal water flow in the pipeline and the device is operating normally.
[0046] When no pulse signal is detected in the control component 10, it means that there is no water flowing through the pipeline, the water tank 1 is short of water, and the water supply of the equipment is abnormal. At this time, the control component 10 will determine that the equipment is abnormal based on the pulse signal of water shortage, and automatically shut down the equipment and prohibit it from being opened, so as to avoid the problem of damage to the pump device due to dry operation due to lack of water.
[0047] In some cases, when the liquid level detection component 101 fails and cannot detect the water level status, the present application can detect the water flow status by further setting a flow rate detection component 4 on the water supply pipe 3. When the water in the water tank 1 dries up, the flow rate detection component 4 can sense that there is no water flow passing through. Since the flow rate detection component 4 in the present application is communicatively connected to the control component 10, it can also transmit the signal to the control component 10, and the pump body 5 can be closed through the control component 10 to ensure the service life of the pump body 5.
[0048] Preferably, the pressure relief member 7 in the present application includes a main body, a movable part and an elastic part. One end of the main body is a water inlet, and the water inlet is connected to the second water outlet end of the pump body 5; the elastic part is arranged in the main body, the movable part is connected to the elastic part, and the movable part can block or open the water inlet.
[0049] The elastic member in the present application is a spring, and the movable part is connected to one end of the spring to form a piston-type structure in the main body. Since one end of the main body is the above-mentioned water inlet, when the water spray gun 6 is closed, the water output by the pump body 5 cannot be discharged through the water spray gun 6, and will flow to the pressure relief component 7. Then, when the water pressure is greater than the thrust of the spring on the movable part, the spring is compressed, and the movable part opens the water inlet, allowing water to enter the main body.
[0050] Since the balancing pipe 9 in the present application is connected to the pressure relief component 7, when the movable part opens the water inlet, water enters the main body and can enter the balancing pipe 9. Since the other end of the balancing pipe 9 is connected to the pressure relief end of the pump body 5, the water entering the balancing pipe 9 can eventually be discharged from the pressure relief end of the pump body 5, thereby achieving pressure relief for the pump body 5.
[0051] Preferably, if Figure 1As shown, the car washing water gun system provided by the present invention also includes a normally closed micro switch 8, which is communicatively connected to the control component 10; a contact part is connected to the movable part, and the contact part can move with the movable part to contact or move away from the normally closed micro switch 8.
[0052] The car wash water gun system provided in the present application forms an overall control system by adding a normally closed microswitch 8. It can be understood that, in the above scheme, although the pressure release can be achieved through the balance pipe 9 and the pressure relief component 7, when the water gun 6 is closed, the pump body 5 is still in operation. Therefore, even if the balance pipe 9 can dump the pressure, the pressure relief end of the pump body 5 is always in a drainage state, which will cause a waste of resources. Therefore, the present application further forms a contact part on the movable part and adds a normally closed microswitch 8 in the system. When the contact part contacts the normally closed microswitch 8, it proves that water has entered the main body and the elastic part is compressed. At the same time, it proves that the water gun 6 is closed and the pump body 5 is in a high-pressure state. At this time, when the water is discharged through the balance pipe 9, the normally closed microswitch 8 will send a signal to the control component 10, thereby realizing the closure of the pump body 5 through the control component 10.
[0053] When the water gun 6 is turned on, the pressure at the water inlet of the pressure relief component 7 decreases, and the spring returns to its initial state, thereby driving the movable part to block the water inlet, and water flows through the pump body 5 to the water gun 6 to realize the water spray cleaning function.
[0054] Preferably, the pump body 5 in the present application is a high-pressure plunger pump, and the control component 10 is communicatively connected to the high-pressure plunger pump.
[0055] In addition, the utility model also provides a car washing machine, which includes the above-mentioned car washing water gun system.
[0056] Since in the car washing water gun system provided by the present application, when the water spray gun 6 stops, the pressure in the pump body 5 can be released, thereby ensuring the stable operation of the pump body 5, avoiding the problem of rupture and damage of the pump body 5, and improving the service life of the car washing water gun system, thereby improving the service life of the entire car washing machine.
[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
