[0021] The following is a clear and complete description of the present invention in conjunction with the accompanying drawings and embodiments:

[0022] like Figures 1 to 5 As shown, a tap water purification and dosing device described in the utility model comprises a box body 1, a delivery pipe 2 is arranged at the bottom end of the box body 1, and the delivery pipe 2 is used to be connected to a pumping mechanism so as to pump the medicine liquid in the box body 1 outward into a tap water storage tank; a sewage pipe 3 is arranged on one side of the delivery pipe 2, which is used to discharge the cleaning water inside the box body 1 in time, and a valve is arranged on the sewage pipe 3 to control the opening and closing of the sewage pipe 3; a dosing port 4 is arranged at the top of one side of the box body 1, a sealing cover 5 is threadedly arranged at the dosing port 4, and a filter screen 6 is arranged in the dosing port 4, which is used to filter the water added to the box body 1 for mixing the medicine liquid; a transparent observation port 7 is arranged on the outside of the box body 1 to observe the amount of medicine liquid inside; in addition, the bottom end of the box body 1 is preferably arranged as a concave structure to facilitate the collection of medicine liquid or cleaning liquid and realize its smooth discharge.

[0023] A frame 8 is provided in the box body 1, and bristles 9 in contact with the inner wall of the box body 1 are provided on the side walls of the frame 8; a hollow accommodating sleeve 10 is provided through the middle of the frame 8, and the accommodating sleeve 10 is rotatably connected to the box body 1; a stirring shaft 11 is movably provided in the accommodating sleeve 10, and the stirring shaft 11 is driven by a motor 17 provided at the upper end of the box body 1; the stirring shaft 11 and the accommodating sleeve 10 are connected through a clutch, and as the rotation direction of the motor 17 is switched, the accommodating sleeve 10 is rotated or stopped under the action of the clutch, so that when only the liquid in the box body 1 needs to be mixed, the accommodating sleeve 10 does not rotate with the rotation of the stirring shaft 11, thereby reducing the large resistance caused by the accommodating sleeve 10 driving the bristles 9 to move along the inner wall of the box body 1, thereby reducing energy consumption; the part of the stirring shaft 11 located in the box body 1 is provided with stirring blades.

[0024] Further, the clutch in this embodiment includes a driving toothed disc 12 arranged on the inner wall of the accommodating sleeve 10, the inner wall of the driving toothed disc 12 is provided with teeth 13, and a driving block 14 is elastically arranged on the stirring shaft 11; when the motor 17 drives the stirring shaft 11 to rotate and stir, the driving block 14 elastically moves along the end surface outside the driving tooth and does not mesh with the teeth 13; when it is necessary to clean the inner wall of the box body 1, the motor 17 reverses and rotates, at which time the driving block 14 abuts against the side surface of the end of the teeth 13, thereby driving the rotation operation of the accommodating sleeve 10. Specifically, a driving disc 15 is coaxially arranged on the stirring shaft 11, and a receiving groove 16 is arranged on the driving disc 15, and the driving block 14 is elastically arranged in the receiving groove 16; during operation, as the rotation direction of the motor 17 is switched, the driving block 14 is tightly meshed or disengaged with the teeth 13 on the driving toothed disc 12, thereby realizing the rotation or stop of the accommodating sleeve 10. Preferably, there is a gap between the drive disk 15 and the stirring shaft 11, and an L-shaped pull rod 18 is provided at one end of the drive block 14 away from the drive gear disk 12, and a positioning rod 19 is elastically provided at the top of the pull rod 18. A positioning groove 20 is provided on the stirring shaft 11, and a positioning hole matching the positioning rod 19 is provided on the top wall of the positioning groove 20. By controlling the positioning rod 19 to enter the positioning hole, the drive block 14 can be ensured to be kept in a stored state at all times, avoiding the contact between the drive block 14 and the teeth 13 in the drive gear disk 12 when the stirring shaft 11 is used alone, further ensuring the smoothness of the rotation of the stirring shaft 11, reducing the wear between the drive block 14 and the teeth 13, reducing energy consumption, and improving economy. At this time, the motor 17 is arranged at the top of the box body 1 through a bracket, and the pull rod 18 is located below the bracket, so as to leave space between the box body 1 and the bracket, and provide convenience for the positioning operation of the pull rod 18.

[0025] Preferably, an adjustment groove 21 is opened on the outside of the pull rod 18, and an adjustment block 23 is elastically arranged in the adjustment groove 21 through a spring 22. A guide rod 24 is arranged at the bottom end of the adjustment block 23, and a guide hole for sliding adjustment of the guide rod 24 is arranged at the bottom end of the adjustment groove 21. The spring 22 is arranged on the outside of the guide rod 24. The positioning rod 19 is movably arranged from the top of the pull rod 18 to the accommodating groove 16 and is connected to the adjustment block 23. When in use, the adjustment block 23 is pulled to drive the positioning rod 19 to move up and down, thereby realizing the positioning or release operation of the pull rod 18.

[0026] Furthermore, the frame 8 is an inverted U-shaped structure, and bristles 9 are provided on both side walls. Preferably, the bristles 9 on both sides of the frame 8 have different densities, that is, one side is dense and the other side is sparse. When the frame 8 rotates, the sparse side is in front and the dense side is in the back. The bristles 9 on the sparse side can be used to first perform a preliminary cleaning of the dirt, and then the bristles 9 on the dense side can be used to perform a comprehensive cleaning of the inner wall of the box body 1. This can not only ensure the cleaning effect, but also avoid the greater resistance caused by the dense arrangement on both sides, thereby reducing energy consumption.

[0027] Furthermore, the box body 1 is a cylindrical structure, wherein two sides of the box body 1 are symmetrically extended outward to form a receiving cavity 25, the longitudinal section of the receiving cavity 25 is rectangular, and the bristles 9 are located in the receiving cavities 25 on both sides in the initial state; the extended arrangement of the receiving cavity 25 can not only enhance the structural strength of the box body 1 and prevent it from deformation, but also provide a receiving space for the bristles 9, thereby enhancing the practicality of the utility model. Previously, the two sides of the receiving cavity 25 were connected to the inner wall of the box body 1 in an arc transition, so that the bristles 9 can pass smoothly through the receiving cavity 25 during the cleaning process.

[0028] When the utility model is in use, when the medicine liquid needs to be stirred and mixed after the addition is completed, the motor 17 is started to drive the stirring shaft 11 to rotate. At this time, the positioning rod 19 on the pull rod 18 is located in the positioning hole, and the driving block 14 is located in the accommodating groove 16, so as to avoid friction contact with the teeth 13 in the driving gear plate 12 to cause loss; when the inner wall of the box body 1 needs to be cleaned, the positioning rod 19 is controlled to move out of the positioning hole, and the driving block 14 is reset and popped out of the accommodating groove 16 under the elastic restoring force, and the motor 17 is reversed. At this time, the driving block 14 will push the teeth 13 to drive the accommodating sleeve 10 to rotate, so as to realize the cleaning operation of the bristles 9 on the inner wall of the box body 1; the entire motor 17 and the subsequent medicine pumping mechanism are connected to the PLC controller to improve the automation and convenience of operation.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
