DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Existing mobile toilets need to be transported as a whole using transportation tools such as cranes and forklifts. Since the entire mobile toilet is large in size and heavy in weight, it is very inconvenient to transport and the transportation cost is very high.

[0022] In view of this, the present invention provides a mobile public toilet, which realizes that by starting a servo motor, the worm is driven to rotate, and the worm wheel is driven to rotate at the same time, so that the traveling wheel is finally rotated to just below the base, so that the traveling wheel can be rotated to the bottom of the base, so that the mobile public toilet is easy to carry, and only two to three workers can carry it, which solves the problem that the existing mobile toilets need to be transported as a whole by means of transportation such as cranes and forklifts. Since the entire mobile public toilet is large in size and heavy in weight, it is very inconvenient to carry and the transportation cost is very high.

[0023] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and appropriate controllers and encoders should be selected according to actual conditions to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principles and processes, and no longer explains the electrical control.

[0024] Embodiment 1: Figure 1-4It can be seen that a mobile public toilet includes a base 1, a toilet body 2 is installed on the top of the base 1, a toilet 3 is arranged inside the toilet body 2, a cabinet door 4 is installed on the front of the outer wall of the toilet body 2, and the user can open the cabinet door 4 to use the toilet 3. A moving mechanism is arranged at the bottom of the base 1, and the moving mechanism includes a servo motor 5, a worm 6, a worm gear 7, a support seat 8, a connecting rod 9, a support frame 10 and a traveling wheel 11. The support seat 8 is fixedly connected to the bottom of the base 1, and the bottom of the support seat 8 is rotatably connected to the connecting rod 9 through a pin shaft. The back of the connecting rod 9 is fixedly connected to the worm gear 7, and the top of the worm gear 7 is meshingly connected to the worm 6. One end of the worm 6 is fixedly connected to the servo motor 5, and the model of the servo motor 5 is not limited. The end of the connecting rod 9 away from the servo motor 5 is movably connected to the support frame 10, and the inner side of the support frame 10 is fixedly connected to the traveling wheel 11. The purpose of such design is to start the servo motor 5, drive the worm 6 to rotate, and also drive the worm gear 7 to rotate, so that the connecting rod 9 can rotate downward;

[0025] In the specific implementation process, it is worth pointing out that starting the servo motor 5 drives the worm 6 to rotate, and also drives the worm wheel 7 to rotate, so that the connecting rod 9 fixedly connected to the worm wheel 7 can rotate downward, so that the support frame 10 and the traveling wheel 11 rotate downward, so that the staff can use the traveling wheel 11 to move, which is convenient for transportation;

[0026] Furthermore, ventilation windows 12 are installed on both sides of the outer wall of the toilet body 2;

[0027] In the specific implementation process, it is worth pointing out that the ventilation window enables the dirty air in the toilet body 2 to be quickly discharged to the outside, thereby maintaining the air quality in the space of the toilet body 2;

[0028] Furthermore, a fixing frame 13 is installed at each of the four corners of the top of the base 1, a screw 14 is threadedly connected to the top of the fixing frame 13, and the outer wall of the screw 14 is threadedly connected to the inner wall of the base 1, and a support block 15 is fixedly connected to the bottom of the screw 14, and an anti-skid layer 20 is provided at the bottom of the support block 15, and the outer wall thread of the screw 14 matches the top inner wall thread of the fixing frame 13 and the inner wall thread of the base 1, respectively, so that the screw 14 can be adjusted in height under the base 1, and the material of the anti-skid layer 20 can be selected from rubber material, so that the support block 15 is not easy to slip, so that the stability of the entire public toilet is improved;

[0029] In the specific implementation process, it is worth pointing out that by adjusting the screws 14 at the four corners of the top of the base 1, the height of the base 1 can be raised or lowered, and it can also keep balance on the sloped ground;

[0030] Furthermore, a partition 16 is fixedly connected to the lower part of the inner wall of the toilet body 2, and a connecting pipe 17 is connected to the bottom of the toilet 3. The connecting pipe 17 passes through the outer wall of the partition 16 and extends downward. One end of the connecting pipe 17 located below the partition 16 passes through the inner wall of the toilet body 2 and extends to the outside thereof. One end of the connecting pipe 17 located outside the toilet body 2 is connected to a collection tank 18, and the collection tank 18 is located behind the toilet body 1;

[0031] In the specific implementation process, it is worth pointing out that the purpose of such a design is that the partition 16 can be stepped on by the user. During the use of sewage discharge, the sewage goes down from the toilet 3 through the connecting pipe 17 into the collection tank 18, thereby maintaining a good effect of the toilet environment, and at the same time, it is convenient for the staff to replace the collection tank 18, and it is also convenient to handle the sewage in the collection tank 18;

[0032] Furthermore, a non-slip strip 19 is provided on the top of the partition 16, and a step block 21 is provided on the front of the toilet body 2;

[0033] In the specific implementation process, it is worth pointing out that the material of the anti-slip strip 19 can be selected from strips that increase friction, such as HDPE polyethylene anti-slip plastic road substrate, which plays a role in increasing friction, preventing the partition 16 from slipping due to water, and preventing users from falling. The step block 21 is also convenient for users to climb onto the base 1 to use the public toilet;

[0034] Specifically, when the mobile public toilet needs to be moved, the servo motor 5 is started to drive the worm 6 to rotate, and the worm wheel 7 is also driven to rotate, so that the connecting rod 9 fixedly connected to the worm wheel 7 can be rotated downward, so that the support frame 10 and the traveling wheel 11 are rotated downward, so that the staff can use the traveling wheel 11 to move, and at the same time adjust the screws 14 at the four corners of the top of the base 1 so that the screws 14 drive the support block 15 to rise. In this way, only 2 to 3 staff members are needed to move the public toilet.

[0035] Embodiment 2: By Figure 1-3 It can be seen that a fixed block 22 is fixedly connected to one side of the inner wall of the connecting rod 9, and a telescopic rod 23 is fixedly connected to the side of the fixed block 22 close to the traveling wheel 11. A shock-absorbing damper 24 is sleeved on the outer wall of the telescopic rod 23, and one end of the shock-absorbing damper 24 is fixedly connected to the fixed block 22, and the other end is attached to the inner wall of the connecting rod 9. The telescopic rod 23 penetrates the inner wall of the connecting rod 9 and extends to the outside thereof. One end of the telescopic rod 23 located outside the connecting rod 9 is fixedly connected to the outer side of the support frame 10;

[0036] In the specific implementation process, it is worth pointing out that the purpose of such design is that when the traveling wheel 11 moves, the support frame 10 is vibrated, and the telescopic rod 23 transmits the vibration to the shock absorbing damper 24, so that most of the vibration is consumed and absorbed by the shock absorbing damper 24, so that the stability of the mobile public toilet is greatly improved when it is moved;

[0037] Specifically, based on the above-mentioned embodiment 1, when the mobile public toilet is used, when the staff moves, the travel wheel 11 will be subjected to pressure, and the support frame 10 will be vibrated. At the same time, the telescopic rod 23 transfers the vibration to the shock absorbing damper 24. Since the shock absorbing damper 24 generates damping to buffer the impact and absorb the vibration, the stability of the mobile public toilet is improved on bumpy roads.
