Description

Technical Field

[0001] This application relates to the field of tap water treatment technology, and more specifically, to a tap water disinfectant dispensing device. Background Technology

[0002] In the prior art, for example, the rapid dispensing device for tap water disinfectant disclosed in CN220684729U includes a cylinder, a cover plate, a dosing pipe, and a rotating shaft. The cylinder is provided with a tangential water inlet and a water outlet. The top of the cylinder is provided with a cover plate, and a rotating shaft is connected to the cover plate. The rotating shaft is a hollow shaft with fins on the upper part. The height of the fins is the same as that of the water inlet. A stirring pipe is provided on the rotating shaft below the fins, and the stirring pipe is connected to the inner hole of the rotating shaft. The dosing pipe is connected to the upper end of the rotating shaft.

[0003] This solution connects the entire device to a tap water pipe. The dosing pipe is connected to a disinfectant delivery pump. Tap water enters the cylinder tangentially from the inlet, impacting the fins. The fins drive the rotating shaft to rotate, and each stirring tube rotates with the shaft. The disinfectant enters the inner hole of the rotating shaft through the dosing pipe and is ejected from the stirring tube. At the same time, the rotating shaft drives the stirring tube to rotate, allowing the disinfectant to mix quickly and thoroughly with the water. This device is directly connected to the tap water pipe, allowing for multi-point disinfectant dosing and automatic mixing.

[0004] However, in this design, the fins drive the rotating shaft to rotate, which in turn drives the stirring tube to rotate synchronously in the same direction. This causes vortices to form in the water inside the cylinder. Once the vortex becomes quite violent, a blank area will form in the water near the fins (the upper part of the shaft), reducing the mixing space of the water. At the same time, it wastes some resources for the stirring tube and disinfectant outlet located in the blank area (the stirring tube in this area cannot stir the water, and although the disinfectant outlet in this area can throw out the disinfectant using centrifugal force, it takes a certain amount of time for the disinfectant to come into contact with the water after being thrown out). In addition, at the bottom of the center of the vortex, "debris" (undissolved particulate drugs) in the water will be gathered, reducing the degree of mixing between the drug and the water. Utility Model Content

[0005] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a tap water disinfectant dispensing device, which aims to improve upon the problem that an existing rapid tap water disinfectant dispensing device forms an internal vortex, resulting in resource waste and affecting the mixing degree of the disinfectant and water to some extent.

[0006] This application discloses a tap water disinfectant dispensing device, comprising a treatment tank, wherein a purified water tank is coaxially arranged around the treatment tank, an inlet pipe is tangentially connected to the side wall of the treatment tank, a dosing hollow shaft is coaxially rotatably connected to the treatment tank, a purified water outlet pipe is connected to the top of the side wall of the purified water tank, and multiple fins and multiple stirring tubes are respectively connected from the top to the bottom of the portion of the dosing hollow shaft inserted into the treatment tank, and multiple flow-damping elements are evenly arranged on the inner wall of the treatment tank, the flow-damping elements being arranged crosswise.

[0007] According to an embodiment of this application, a tap water disinfectant dispensing device has the following advantages: the power generated by tap water entering the treatment tank drives the fins to rotate the dispensing hollow shaft, which in turn drives the stirring tube to agitate the water. During the agitation, the water is obstructed by multiple flow-suppressing elements to prevent the water in the treatment tank from forming a vortex. The dispensing hollow shaft adds disinfectant to the water. By agitating and suppressing the agitation of the water in the treatment tank, the disinfectant disinfects the water. The purified water enters the clean water tank from the bottom of the treatment tank and is then discharged.

[0008] In addition, a tap water disinfectant dispensing device according to an embodiment of this application also has the following additional technical features:

[0009] In some specific embodiments of this application, the bottom end of the treatment tank is connected to the purified water tank, and a plurality of support strips are evenly arranged circumferentially on the inner bottom end of the purified water tank, and the treatment tank is pressed against the support strips.

[0010] In some specific embodiments of this application, the height of the water inlet pipe and the height of the purified water outlet pipe are the same.

[0011] In some specific embodiments of this application, a plurality of drug outlet holes are uniformly arranged on the hollow drug delivery shaft, and the plurality of drug outlet holes and the plurality of stirring tubes are spaced apart axially.

[0012] In some specific embodiments of this application, multiple fins are inclined at the same angle, and multiple fins are spirally arranged along the axial direction of the drug delivery hollow shaft.

[0013] In some specific embodiments of this application, the flow-suppressing elements are uniformly arranged axially on the inner wall of the treatment tank, and a plurality of the flow-suppressing elements are uniformly arranged circumferentially on the inner wall of the treatment tank.

[0014] In some specific embodiments of this application, the flow-suppressing component includes a first flow-suppressing plate and a second flow-suppressing plate fixedly connected together, with the first flow-suppressing plate and the second flow-suppressing plate being arranged crosswise.

[0015] In some specific embodiments of this application, the first flow deflector and the second flow deflector are symmetrically inclined, and both the first flow deflector and the second flow deflector are arranged with an outer higher and inner lower profile. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] like Figures 1-4As shown, a tap water disinfectant dispensing device according to an embodiment of this application includes a treatment tank 1, wherein a purified water tank 11 is coaxially arranged around the treatment tank 1, the bottom end of the treatment tank 1 is connected to the purified water tank 11, and a plurality of support strips 111 are evenly arranged around the inner bottom end of the purified water tank 11. The treatment tank 1 is pressed against the support strips 111, so that the bottom of the treatment tank 1 and the purified water tank 11 are connected, and the presence of the plurality of support strips 111 also suppresses the possibility of water forming vortices to a certain extent.

[0024] like Figures 1-3 As shown, a water inlet pipe 12 is tangentially connected to the side wall of the treatment tank 1, and a purified water outlet pipe 14 is connected to the top of the side wall of the purified water tank 11. The height of the water inlet pipe 12 and the height of the purified water outlet pipe 14 are the same. It should be noted that, in the specific embodiment of this application, the water inlet pipe 12 and the purified water outlet pipe 14 are respectively connected to the tap water pipe, so that the unsterilized tap water enters the interior of the treatment tank 1 through the water inlet pipe 12, and the sterilized tap water is transported to the tap water pipe behind through the purified water outlet pipe 14.

[0025] like Figures 1-3 As shown, a hollow drug delivery shaft 13 is coaxially rotatably connected to the treatment tank 1. The part of the hollow drug delivery shaft 13 inserted into the treatment tank 1 is connected to multiple fins 2 and multiple stirring tubes 132 from the top to the bottom. Multiple flow-suppressing elements 3 are evenly arranged on the inner wall of the treatment tank 1, and the flow-suppressing elements 3 are arranged in a cross pattern.

[0026] The hollow shaft 13 for drug delivery is uniformly provided with multiple drug outlet holes 131. The multiple drug outlet holes 131 and multiple stirring tubes 132 are spaced apart in the axial direction. The drug outlet holes 131 can be used to release disinfectant fed from the direction of the hollow shaft 13 into the water. The drug outlet holes 131 and stirring tubes 132 are spaced apart in the axial direction to facilitate better mixing between the water and the disinfectant.

[0027] like Figure 2 and Figure 4 As shown, multiple fins 2 are inclined at the same angle and spirally arranged along the axial direction of the drug delivery hollow shaft 13. It should be noted that the spiral direction of the fins 2 is consistent with the spiral falling direction of the water entering through the water inlet pipe 12. This will allow the water to have a better impact on the multiple fins 2, so that the drug delivery hollow shaft 13 can drive the multiple stirring tubes 132 to rotate better.

[0028] like Figure 2 and Figure 3As shown, the flow-suppressing components 3 are uniformly arranged axially on the inner wall of the treatment tank 1, and multiple flow-suppressing components 3 are uniformly arranged circumferentially on the inner wall of the treatment tank 1. The flow-suppressing components 3 include a first flow-suppressing plate 31 and a second flow-suppressing plate 32 fixed together. The first flow-suppressing plate 31 and the second flow-suppressing plate 32 are arranged crosswise. It can be seen that when the water is agitated in the same direction, a vortex will be formed. During the rotation of the water, it is intercepted by the crosswise first flow-suppressing plate 31 and the second flow-suppressing plate 32, causing the water to form turbulent flow during the rotation, reducing the force of vortex formation. The multiple first flow-suppressing plates 31 and the second flow-suppressing plate 32, which are uniformly arranged axially and circumferentially, will reduce the possibility of vortex formation as much as possible.

[0029] Furthermore, the first baffle plate 31 and the second baffle plate 32 are symmetrically inclined, and both the first baffle plate 31 and the second baffle plate 32 are arranged with the outer side higher than the inner side. It can be understood that after the water body forms a vortex, part of the water body will rise from the bottom to the top of the vortex while rotating. The first baffle plate 31 and the second baffle plate 32, which are inclined inward, will suppress and obstruct this displacement, thus further suppressing the formation of the vortex. At the same time, after the water body is suppressed, it will form turbulence, which will be more conducive to the mixing between the water body and the disinfectant.

[0030] Furthermore, it can be understood that during the process of the water entering the purification tank 11 from the treatment tank 1, it will be obstructed by multiple support bars 111, causing the water to be segmented before entering the purification tank 11, further enhancing the mixing degree of the water and disinfectant, while further weakening the formation of vortex.

[0031] It should be noted that the specific model and specifications of the treatment tank 1 and the purified water tank 11 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0032] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
