Detailed Description of the Preferred Embodiments In order to make the object, technical solutions and advantages of the present invention clearer, the present invention is further described in detail in conjunction with embodiments. It should be appreciated that the specific embodiments described herein only serve to illustrate the present invention, and should not be construed as limitation thereto.
The application principle of the present invention is described in detail below in combination with the drawings.
As shown in Figs. 1 to 4, a direct-swirl mixed jet nozzle for a ground cleaning trolley comprises a nozzle body 1, an impeller 2 and an expansion section 3. A left end of the nozzle body 1 is provided with an internal thread la, a right end of the internal thread 1a is connected with a step section I 1b and a step section II 1c, a right end of the step section II 1c is connected with a mixing chamber 1d, a right end of the mixing chamber 1d is connected with a front nozzle le, and a right end of the nozzle body 1 is provided with an external thread 1f connected with the expansion section 3.
A circumferential surface of the impeller 2 is evenly provided with a number of spiral impeller grooves 2a with two opposite sides parallel to each other. The spiral impeller grooves 2a run through both ends of the impeller 2 and are open to the outside. Two parallel planes of the spiral impeller grooves 2a are at a certain angle with an axis of the impeller 2. A center at the end surfaces of the impeller 2 is provided with a direct jet orifice 2b running through the both end surfaces of the impeller 2. The impeller 2 is arranged in the step section II 1c.
A left end of the expansion section is provided with the internal thread 3a, and a right end 350 1329 thereof is connected with a conical hole 3c whose diameter increases from left to right. A conical orifice 3b has the same diameter as and is closely connected with an orifice of the front nozzle le of the nozzle body 1.
As shown in Fig. 5, an automatic cleaning trolley for ground cleaning comprises an automatic walking controller, a trolley body 4, a cleaning device 5 and a ground mopping device 6. The body 4 of the ground cleaning trolley 1s controlled to walk by the controller. The cleaning device 5 and the ground mopping device 6 are arranged at a bottom of the ground cleaning trolley body and face the ground. The cleaning device 5 1s located at a front of the automatic cleaning trolley in a horizontal direction, and comprises sequentially arranged nozzle holders 501, a hose 502, a water tank 503, a water pump 504 immersed in the water tank, and three nozzle holders 501 are arranged at intervals at the bottom of the trolley body. The three nozzle holders 501 are arranged facing the ground and perpendicular to a body direction of the ground cleaning trolley, and a distance from the nozzle holders to the ground can be adjusted manually. The water tank 503 is arranged inside the automatic cleaning trolley body 1, and both ends of the hose 502 are connected to the nozzle holders and the water tank respectively. The ground mopping device 6 is located at a rear of the automatic cleaning trolley in the horizontal direction, and comprises a mophead 602 driven by the motor 601, and the motor 601 drives the mophead 602 to move around an axis on a horizontal plane. The controller controls operation of the water pump 504 and the motor 601. The direct-swirl mixed jet nozzle is detachably connected to the nozzle holders 501 in the cleaning device 5.
To sum up, the working principle of the present invention is as follows: Firstly, the ground cleaning trolley automatically walks on the stained ground under the control of the controller, and the controller controls the operation of the water pump 504. The water pump 504 transports cleaning water to the step section I 1b in the direct-swirl mixed jet nozzle body 1 by means of the hose 502. The cleaning water generates direct-swirl mixed jet in the mixing chamber 1d under the joint action of the spiral impeller grooves 2a and the direct jet orifice 2b. Therefore, the jet ejected from the expansion section 3 has stronger cleaning force and wider cleaning coverage. Then, the motor 601 in the mopping device 6 drives the mophead 602 to rotate to further clean the ground. Thus, the cleaning effect is good, and no manual treatment is needed.
The above descriptions are only the best embodiments of the present invention and are nof 501329 intended to limit thereto.
Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention. 5
