In this embodiment, the apertures of the three nozzles are preset apertures, respectively, the aperture of the first nozzle 15 is 1mm, the aperture of the second nozzle 16 is 1.5mm, and the aperture of the third nozzle 18 is 2 mm. Car washing personnel can select proper steam pressure according to the spray heads with different calibers.
The spray gun further comprises a positioning mechanism, the positioning mechanism is provided with a first clamping groove 8, a second clamping groove 9 and a third clamping groove 10, and the distance between the three clamping grooves is matched with the distance between the three spray heads with different calibers. In this embodiment, the clamping grooves are arc-shaped, three clamping grooves are arranged at equal intervals and are installed on the spray gun, and the clamping grooves and the cavity 20 have a preset distance. When the other end of the switching handle 11 is clamped in one of the clamping grooves, two ends of the nozzle body move under the elastic action of the elastic piece 19, and one nozzle in the nozzle body is respectively communicated with the jet hole 17 and the pipeline 1.
The elastic members 19 in the adjusting mechanism are divided into two groups, wherein the same end of one group of elastic members 19 is positioned in the cavity 20, and the same other end is connected with one end of the spray head body; wherein the same end of the other group of elastic elements 19 is connected with the other end of the spray head body, and the same other end is connected with one end of the switching handle 11; switching handle 11 can move the head body in the direction of arrangement of the plurality of heads by pulling another one of the elastic members 19 so that one of the heads is butted against ejection hole 17. In this embodiment, considering that the upper and lower layers of the elastic member 19 include springs, in order to make the device uniformly stressed when switching the nozzles, the two groups of springs of the elastic member 19 adopt the same specification and adopt the same pre-tightening force when installing.
One end of a switching handle 11 in the adjusting mechanism is connected with the other end of the other group of elastic pieces 19, and the other end of the switching handle is matched with the positioning structure and is used for being clamped into the first clamping groove 8, the second clamping groove 9 and the third clamping groove 10. In this embodiment, the preset distance between the positioning structure and the cavity 20 enables the nozzle switching handle 11 to be clamped into the positioning structure and not to be affected during switching, and when the nozzle switching handle 11 is clamped into the positioning structure, the nozzle can be just switched to one of the nozzle bodies, and the nozzle is communicated with the injection hole 17 and the pipeline 1.
The pipe 1 is installed in the spray gun body 2, and the pipe 1 is connected to an external steam car washer. The spray gun body 2 is also provided with a spray hole 17, and the spray hole 17 is coaxial with the pipeline 1. In this embodiment, the pipe 1 can be supplied with either water or steam, which reaches the spray holes 17 through the pipe 1 and exits through the spray head body switched by the car washer.

In the present embodiment, the control switch 7 is used to control the on/off of water or steam in the pipeline 1. When a carwash person forcibly holds down the control switch 7 to switch on the pipeline 1 and releases the control switch 7 by hand, the control switch 7 can automatically return to block the pipeline 1 under the action of the spring 21. Meanwhile, in order to relieve the fatigue of a car washer holding the control switch 7 for a long time, after holding the control switch 7, the connecting rope is hung on the hook 5, and then the control switch 7 is released by hands, so that the pipeline 1 is always in an on-state. When the pipeline 1 needs to be closed, the connecting rope 6 is only required to be taken off from the hook 5, then the control switch 7 automatically restores to the original position under the action of the elastic force of the spring 21, and the pipeline 1 is cut off.
Because of the high steam pressure output by the steam car washer, it is difficult to operate the nozzle switch handle 11 in the presence of steam pressure. For the convenience of operation, the connection cord 6 should be first loosened to turn off the control switch 7 before the nozzle switch lever 11 is operated, and the nozzle switch lever 11 should be operated after the pressure in the pipe 1 is reduced.

Because the movable rod 24 is rotatably connected with the control switch 7, a carwash worker presses the control switch 7 to drive the movable rod 24 and the partition plate 23 to move upwards and compress the spring 21, the pipeline 1 is connected, then the connecting rope 6 is hung on the hook 5, the gripping force of the hand of the operator is replaced by the tightening force of the connecting rope 6, the pipeline 1 is always in a connected state, and the carwash worker does not need to press the control switch 7 all the time, so that the working intensity of the carwash worker is greatly reduced.
Referring to fig. 2, when a car washer pulls the nozzle switching handle 11 downward to be clamped into the third clamping groove 10, the nozzle is the third nozzle 16, the diameter of the nozzle is 1.5mm, and when the pipeline 1, the jet hole 17 and the third nozzle 18 are communicated, water or steam can be jetted from the third nozzle 16. Because the movable rod 24 is rotatably connected with the control switch 7, a carwash person presses the control switch 7 to drive the movable rod 24 and the partition 23 to move upwards and compress the spring 21, the pipeline 1 is connected, then the connecting rope 6 is hung on the hook 5, and the tightening force of the connecting rope 6 replaces the holding force of the hand of an operator to keep the pipeline 1 in a connected state.
Referring to fig. 3, when the diameter of the nozzle is adjusted to 1mm, a car washer pulls the nozzle switching handle 11 to move the nozzle to the slot 8 and then clamp the nozzle, and the nozzle 15 is communicated with the pipeline 1 and the injection hole 17. The carwash personnel hold down the control switch 7 with the hand, drive push rod 24 and baffle 23 and move upwards and compress spring 21, pipeline 1 switches on, then hang the interlinking rope 6 on couple 5, replace the grip of operating personnel hand by the power of tightening of interlinking rope 6, make pipeline 1 in the on-state always.
Referring to fig. 4, when the car needs to be paused or the car is washed, the connecting rope 6 is loosened from the hook 5, for example, when the caliber is adjusted to 1mm, and the connecting rope 6 is in a natural sagging state. The diaphragm 23 and the push rod 24 are pushed to move downward by the elastic restoring force of the spring 21 until the diaphragm 23 blocks the pipe 1 to break the pipe 1. When the aperture is adjusted to 1.5mm and 2mm, the structure is the same.
The driving mechanism is used for driving the switching handle 11 to move in the arrangement direction. The drive mechanism may comprise an electric telescopic device which can move the switching handle 11 relative to the gun body 2 by telescoping the free end thereof. The electric telescopic device can be directly installed on the spray gun body 2, and also can be installed on the spray gun body 2 through other structures. The electric telescopic device can be an electric push-pull rod, a linear motor and other telescopic electric devices. Actuating mechanism can also include the protective housing, and the protective housing can protect electronic flexible device, prevents that the outside from producing the destruction to electronic flexible device.
The controller is used for firstly inputting the aperture value required to be sprayed, then detecting the flow rate of the cavity 20 in a unit time, then inquiring the real-time spraying aperture corresponding to the flow rate in a preset flow rate-spraying aperture comparison table, and finally comparing whether the aperture value is equal to the real-time spraying aperture or not. Since different injection calibers generate different injection quantities, the injection calibers can be determined by the relationship between the injection quantities and the injection calibers. And when the caliber value is equal to the real-time injection caliber, the controller judges that the real-time injection caliber reaches the caliber value. When the caliber value is not equal to the real-time injection caliber, the controller firstly inquires a target position corresponding to the caliber value and a real-time position corresponding to the real-time injection caliber in a preset nozzle distribution model, compares a position difference value between the target position and the real-time position, inquires a displacement corresponding to the position difference value in a preset difference value-displacement comparison relation table, and finally drives the switching handle 11 to move the displacement through the driving mechanism so as to enable the nozzle corresponding to the caliber value to be in butt joint with the injection hole 17. Therefore, a user only needs to input the caliber value, the controller processes the data and then drives the switching handle 11 to control, and the actually required spray head is in butt joint with the spray hole 17, so that the function of automatically adjusting the caliber of the spray gun is realized.
The power supply is mounted on the gun body 2 and is used to supply power to the drive mechanism and the controller. The power supply can be devices such as a common battery, can also be a rechargeable battery such as a lithium battery, and can also be other rechargeable modules.

The power supply can be installed in the spray gun body 2 through protective casings such as a battery box, and voltage can be modulated through related voltage regulating elements, so that the spray gun can be continuously used.
In summary, the invention provides an aperture-adjustable high-temperature high-pressure steam car-washing spray gun, which comprises a spray head body consisting of three spray heads with different apertures, so that the spray head of the spray gun has a spray head which can be selected by car-washing personnel. The clamping groove and the spray head switching handle 11 enable the spray gun to adjust the caliber more easily; the carwash personnel can press the control switch 7, and after the pipeline 1 is connected, the connecting rope 6 can be hung on the hook 5 to replace manpower, so that the manpower consumption is saved. The multilayer sound insulation net and the heat insulation layer of the embodiment have a protection effect on car washing personnel: the sound insulation net has the noise reduction function, so that car washing personnel can not damage eardrum after long-time use; the heat insulation layer is formed by sandwiching heat insulation cotton between two layers of stainless steel materials, and protects car washing personnel from being scalded when in use.
The controller of the high-temperature high-pressure steam car-washing spray gun with the adjustable caliber can be used for inputting a required caliber value from the outside, detecting the flux of the inner cavity 20, inquiring the real-time spraying caliber according to a preset relation, finally comparing the real-time spraying caliber with the caliber value, and judging whether the spray head with the corresponding radius is aligned with the spray hole according to the comparison result. When the caliber of the spray head is not the required caliber of the spray gun, the controller inquires a target position in a preset spray nozzle distribution model, also inquires a real-time position, compares a position difference value, then inquires a displacement in a difference value-displacement comparison relation table, and finally drives the switching handle 11 to enable the spray head corresponding to the caliber value to be in butt joint with the spray hole 17, so that the function of automatically adjusting the caliber is realized. Therefore, when the user needs to adjust the corresponding aperture value, the user only needs to input corresponding data to realize the adjustment through the controller, so that the adjustment process is full-automatic, the adjustment precision is high, and the adjustment is very convenient and efficient.
