Description

Technical Field

[0001] The invention relates to the technical field of water treatment, in particular to a dental pipe water sterilizer which is easy to maintain. Background Art

[0002] Dental pipe water disinfection refers to the disinfection of the water system used in dental treatment to ensure that the water provided to patients is clean and sterile. In dental clinics, the water system includes water pipes in the dental chair unit, high-speed mobile phones (dental drills), low-speed mobile phones, three-purpose spray guns and other equipment. These devices will come into contact with the patient's mouth during use, so it is very important to keep the water system clean to prevent the spread of bacteria, viruses and other microorganisms.

[0003] During the water circulation disinfection process, a professional disinfector is usually used to add sodium chlorate disinfectant to clean the biofilm and other adhesion layers on the pipes and the inner wall of the pipes. However, many commonly used water disinfectors are only equipped with simple filter plates, which are prone to clogging when faced with a large amount of attachments. This will not only interfere with the normal circulation disinfection process, but may also cause impurities to flow back during static disinfection, further affecting the disinfection effect. In addition, when the filter plate is clogged, maintenance work becomes complicated and time-consuming, and it is difficult to quickly solve the problem.

[0004] Based on the above situation, the present invention provides a dental pipe water sterilizer which is easy to maintain. Summary of the invention

[0005] In order to overcome the shortcoming that impurities are not easy to be cleaned from a pipeline sterilizer, the present invention provides a dental pipeline water sterilizer which is easy to maintain.

[0006] A dental pipeline water sterilizer that is easy to maintain, comprising a water channel sterilizer shell, a shell cover fixedly connected to the water channel sterilizer shell, a circulating pump fixedly connected to the interior of the water channel sterilizer shell, a water tank symmetrically distributed along the water channel sterilizer shell fixedly connected to the interior of the water channel sterilizer shell, a plug inserted into the upper side of the water channel sterilizer shell, the plug is used to block the water tank on one side, the plug is opened, and disinfectant water is put into the water tank on the side, one side of the water channel sterilizer shell is penetrated and fixedly connected with water pipes symmetrically distributed along the water channel sterilizer shell, the water pipes correspond to the water tanks one by one, and the water pipes are connected to the corresponding water tanks, and the inner and outer sides of one side of the water channel sterilizer shell are connected to the inner and outer sides of the water channel sterilizer shell. A one-way valve tube is fixedly connected through the filter frame, which is connected to the water tank on the other side. A filter frame is fixedly connected to the water tank on the side close to the one-way valve tube, and a gap for water to flow through is left between the bottom of the filter frame and the inner bottom of the adjacent water tank. A rotating frame is rotatably connected to the water tank on the side close to the plug, and the rotating frame is located directly below the plug. A push frame is slidably connected to the filter frame, and the push frame passes through one side of the adjacent water tank. A reciprocating threaded groove is opened inside the rotating frame, and the rotating frame is threadedly connected to the push frame via the reciprocating threaded groove. A through hole is opened on the side of the push frame close to the filter frame, and a rotating plate is rotatably connected to the side of the push frame close to the through hole, and the rotating plate blocks the through hole.

[0007] Furthermore, a side of the filter frame close to the water pipe is configured as an inclined surface, and a middle portion of the filter frame is configured as a U-shaped portion.

[0008] Furthermore, the one-way valve pipe is composed of a drain pipe, a cross, an annular frame, a compression spring and a valve plate. The drain pipe is connected to the adjacent water tank. The cross and the annular frame are both fixed in the drain pipe. The compression spring is fixed to the cross. The valve plate is fixed to one end of the compression spring. The annular frame has annularly distributed fan-shaped holes, and the valve plate is used to block all the fan-shaped holes.

[0009] Furthermore, it also includes a rotating rod, which is rotatably connected to the annular frame of the one-way valve tube, and a cylindrical hole is opened inside the push frame, and the hole is plugged into the rotating rod. The rotating rod has a spline groove, and the rotating rod is slidably connected to a rotating fan through the spline groove. The rotating rod is slidably connected to a stirring frame through the spline groove, and the push frame moves to contact the stirring frame, and a spring is fixed between the rotating fan and the stirring frame.

[0010] Furthermore, the hole and the rotating rod are located on the same horizontal line, and the diameter of the hole is not less than the diameter of the rotating rod.

[0011] Furthermore, it also includes elastic cards symmetrically distributed along the valve plate, the elastic cards are fixedly connected to the valve plate, the rotating fan is rotatably connected to a slide cylinder, the rotating rod passes through the inside of the slide cylinder, and the slide cylinder is squeezed and matched with the elastic cards.

[0012] Furthermore, a side of the annular frame of the one-way valve tube close to the slide cylinder is arranged as a locking surface, and the elastic card passes through the fan-shaped hole of the annular frame and is locked on the locking surface.

[0013] Furthermore, it also includes a magnet, which is fixed to the bottom of the filter frame on one side close to the push frame, and a notch is opened on the side of the push frame close to the magnet. A magnetic stopper is slidably connected to the side of the push frame close to the notch, and the magnetic stopper blocks the notch. The magnetic stopper cooperates with the magnet through repulsive magnetic forces.

[0014] Furthermore, a U-shaped bracket is also included, which is slidably connected to the side of the push frame close to the magnetic stop block, the push frame is fixed to the magnetic stop block, and an arc groove is opened on the side of the U-shaped bracket close to the rotating plate, and the arc groove is used to limit the rotating plate so that the rotating plate cannot be rotated open.

[0015] Furthermore, it also includes an adjusting plate for adjusting water pressure, which is slidably connected to the water tank near the one-way valve pipe. The adjusting plate is close to the water pipe, and a screw is threadedly connected to the water tank near the one-way valve pipe. The screw is rotatably connected to the adjusting plate.

[0016] The beneficial effects are as follows: the present invention automatically rotates the rotating frame through water flow impact, thereby fully mixing water with sodium chlorate disinfectant water, achieving the cleaning of the dental water system, filtering impurities through the filter frame, and at the same time, the rotating frame drives the push frame to push to the right along the filter frame, achieving the effect of automatic filtering and discharging impurities, and reducing blockage.

[0017] In the process of the push frame pushing the impurities to the right, the rotating fan rotates to rotate the stirring frame, so that the stirring frame stirs and mixes the impurities and water, making it easier for the impurities to flow out in the form of a solution.

[0018] The present invention locks the valve plate in the one-way valve tube by buckling the elastic card on the locking surface, and the valve plate will be unlocked only when the push frame moves to contact the stirring frame, so as to prevent the valve plate in the one-way valve tube from opening due to the lateral pressure of water in the right water tank, thereby preventing the circulating water from leaking.

[0019] The present invention cooperates with the magnetic force of the magnetic stopper and the magnet to repel each other, so that when the push frame moves to the left and is close to the leftmost side, the gap at the bottom of the push frame is opened, and the impurities on the left side of the push frame flow to the right side along the gap, avoiding that some impurities are blocked on the left side when the push frame returns.

[0020] When the push rack moves to the left and is close to the leftmost side, the present invention closes the through hole at the rotating plate and opens the gap so that only one outlet is open. Compared with opening two outlets, the closed area of ​​the push rack is larger, so that the impurity solution between the push rack and the left side of the inner wall of the filter rack is subjected to a greater squeezing force, thereby making it easier to flow out to the right side of the push rack.

[0021] The present invention drives the adjusting plate to move up and down by rotating the screw rod, and can adjust the passage diameter between the right water pipe and the right water tank, so as to adapt to the actual use requirements of different water pressures of the dental water system.

DETAILED DESCRIPTION

[0035] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.

[0036] Embodiment 1: A dental pipe water sterilizer that is easy to maintain, such as Figure 1-Figure 5As shown in the figure, it includes a waterway disinfector housing 1. The top of the waterway disinfector housing 1 is fixedly connected with a housing cover 2 by means of bolts. A circulation pump 3 is fixedly connected to the rear side inside the waterway disinfector housing 1. Water tanks 4 symmetrically distributed along the left and right of the waterway disinfector housing 1 are fixedly connected to the front side inside the waterway disinfector housing 1. A plug 5 is inserted into the front part of the upper side of the waterway disinfector housing 1. The plug 5 is used to block the left water tank 4. Open the plug 5 and pour the disinfectant water into the left water tank 4. Water pipes 6 symmetrically distributed along the left and right of the waterway disinfector housing 1 are fixedly connected through the front side inside and outside of the waterway disinfector housing 1. The water pipes 6 correspond to the water tanks 4 one by one, and the water pipes 6 are communicated with the corresponding water tanks 4. A one-way valve pipe 7 is fixedly connected through the right side inside and outside of the waterway disinfector housing 1. The one-way valve pipe 7 is communicated with the right water tank 4. The one-way valve pipe 7 is composed of a drain pipe, a cross, an annular frame, a compression spring and a valve plate. The drain pipe is communicated with the adjacent water tank 4. The cross and the annular frame are both fixedly connected inside the drain pipe. The compression spring is fixedly connected to the cross. The valve plate is fixedly connected to one end of the compression spring. Four fan-shaped holes are distributed in an annular shape on the annular frame. The valve plate is used to block all the fan-shaped holes. A filter rack 8 is fixedly connected inside the right water tank 4. The front side of the filter rack 8 is set as an inclined surface to guide the separated water to the lower part and the separated impurities to the middle of the filter rack 8. The middle part of the filter rack 8 is set as a U shape. A gap for water flow is left between the bottom of the filter rack 8 and the inner bottom of the adjacent water tank 4. A rotating rack 9 is rotatably connected inside the left water tank 4. The rotating rack 9 is located directly below the plug 5. A pushing rack 10 is slidably connected in the filter rack 8 along the left and right directions. The pushing rack 10 penetrates the left side of the right water tank 4. A reciprocating thread groove 11 is opened inside the rotating rack 9. The rotating rack 9 is threadedly connected with the pushing rack 10 through the reciprocating thread groove 11. A through hole is opened in the upper right part of the pushing rack 10. A rotating plate 12 is rotatably connected to one side of the pushing rack 10 close to the through hole. The rotating plate 12 blocks the through hole.

[0037] First, open the plug 5 and pour the sodium chlorate disinfectant water into the left water tank 4. Then cover the plug 5 and start the circulation pump 3, so that the sewage in the dental waterway system pipeline is pumped into the right water tank 4 through the right water pipe 6. The solid impurities in the sewage are filtered and left in the filter rack 8. The filtered water flows into the circulation pump 3 and then flows out of the circulation pump 3 into the left water tank 4. Under the impact of the water flow, the rotating rack 9 automatically rotates, so as to fully mix the water and the sodium chlorate disinfectant water to clean the pipeline of the dental waterway system and the adhesion layers such as biofilms on the inner wall of the pipeline. The water flow of the mixed disinfectant water is then discharged through the left water pipe 6. In this way, the cycle is carried out to realize the cleaning of the dental waterway system.

[0038] During the above-mentioned circulation process, the reciprocating thread groove 11 rotates synchronously with the rotating frame 9, thereby driving the pushing frame 10 to move back and forth left and right. When the pushing frame 10 moves to the right, the pushing frame 10 and the rotating plate 12 gradually push the impurities deposited in the filter frame 8 to the right into the one-way valve tube 7. Since the filter frame 8 contains a small amount of water in addition to impurities, the impurities flow out through the one-way valve tube 7 along with the small amount of water. The pushing frame 10 and the rotating plate 12 move to the right until they contact the right inner wall of the water tank 4 on the right side, and then move to the left. During the process of moving to the left, the rotating plate 12 will be rotated to the right in one direction under the action of water pressure and open. The water flows through the through hole into the space between the pushing frame 10 and the right inner wall of the water tank 4 on the right side, avoiding the closed space causing the pushing frame 10 to be unable to move to the left and reset.

[0039] In summary, the present invention automatically rotates the rotating frame 9 through the impact of water flow, so that the water and the sodium chlorate disinfectant are fully mixed, the dental water system is cleaned, and impurities are filtered through the filter frame 8. At the same time, the rotating frame 9 drives the push frame 10 to push to the right along the filter frame 8, so as to achieve the effect of automatic filtering and discharge of impurities and reduce blockage.

[0040] Embodiment 2: Based on embodiment 1, Figure 6 and Figure 7 As shown, it also includes a rotating rod 13, which is rotatably connected to the annular frame of the one-way valve tube 7. A cylindrical hole 131 is opened inside the push frame 10, and the hole 131 and the rotating rod 13 are located on the same horizontal line, and the diameter of the hole 131 is equal to the diameter of the rotating rod 13. The hole 131 and the rotating rod 13 are plugged together, and the rotating rod 13 has a spline groove. The rotating rod 13 is slidably connected to the rotating fan 14 in the left and right directions through the spline groove. The rotating rod 13 is slidably connected to the stirring frame 15 in the left and right directions through the spline groove. The stirring frame 15 is located on the left side of the rotating fan 14. The push frame 10 moves to the right and contacts the stirring frame 15. A spring 16 is fixed between the rotating fan 14 and the stirring frame 15.

[0041] When the push frame 10 pushes the impurities to the right, the rotating rod 13 will penetrate into the push frame 10 through the hole 131. When the push frame 10 pushes the impurities to the right, it will drive a small amount of water in the filter frame 8 to flow to the right. Under the impact of the water flow, the rotating fan 14 rotates, thereby driving the rotating rod 13 to rotate, and then driving the stirring frame 15 to rotate, so that the stirring frame 15 stirs and mixes the impurities and water, making it easier for the impurities to flow out in the form of a solution. At the same time, the push frame 10 will contact the stirring frame 15 during the movement to the right, and after the contact, it will push the stirring frame 15 to slide to the right synchronously, and the spring 16 will be compressed. When the push frame 10 is reset to the left, the rotating rod 13 is gradually pulled out of the hole 131, and the spring 16 is gradually reset to drive the stirring frame 15 to slide to the left.

[0042] like Figure 8 and Fig. 9As shown, it also includes elastic cards 17 symmetrically distributed along the upper and lower parts of the valve plate, the elastic cards 17 are fixedly connected to the valve plate, the right side of the rotating fan 14 is rotatably connected to the slide cylinder 18, the rotating rod 13 passes through the inside of the slide cylinder 18, the right end of the slide cylinder 18 is squeezed and fitted with the left end of the elastic card 17, and the side of the annular frame of the one-way valve tube 7 close to the slide cylinder 18 is set as a locking surface 19, and the elastic card 17 passes through the fan-shaped hole of the annular frame and is locked on the locking surface 19.

[0043] In addition to being pushed to the right by the push frame 10 pushing the impurities and water to the right, the valve plate in the one-way valve tube 7 may also be opened by the lateral pressure of the water in the right water tank 4, resulting in leakage of circulating water. To avoid this situation, the elastic card 17 is first buckled on the locking surface 19 to lock the valve plate in the one-way valve tube 7, so that it will be unlocked only in the following circumstances: when the push frame 10 moves to contact with the stirring frame 15, the stirring frame 15 is pushed by the push frame 10, and the rotating fan 14 is pushed to the right to the rightmost end of the spline groove through the spring 16, thereby driving the slide cylinder 18 to move to the right, and the slide cylinder 18 opens the elastic card 17, so that the elastic card 17 no longer locks the valve plate in the one-way valve tube 7, and the impurity solution can be discharged.

[0044] When the push frame 10 moves in the opposite direction to disengage from the stirring frame 15, the spring 16 resets and drives the rotating fan 14 and the stirring frame 15 to slide to the left along the rotating rod 13 to reset, and the rotating fan 14 drives the slide cylinder 18 to move to the left, and the valve plate in the one-way valve tube 7 pushes the elastic card 17 to be re-locked on the locking surface 19.

[0045] Embodiment 3: Based on embodiment 2, Fig.10 As shown, it also includes a magnet 20, which is fixed to the left side of the bottom of the filter frame 8. A notch is opened on the side of the push frame 10 close to the magnet 20. A magnetic stopper 21 is slidably connected to the side of the push frame 10 close to the notch along the up and down directions. The magnetic stopper 21 blocks the notch, and the magnetic stopper 21 cooperates with the magnet 20 through repulsive magnetic forces.

[0046] When the push rack 10 moves to the right, the push rack 10 drives the magnetic stopper 21 to move to the right away from the magnet 20. At this time, under the action of gravity, the magnetic stopper 21 moves downward to block the gap at the bottom of the push rack 10, so that the push rack 10, the rotating plate 12 and the magnetic stopper 21 jointly push the impurity solution on the right side of the push rack 10 to the right along the filter rack 8. When the push rack 10 moves to the left, the push rack 10 drives the magnetic stopper 21 to move to the left close to the magnet 20. When the magnetic stopper 21 is located directly above the magnet 20, it is affected by the repulsive magnetic force and slides upward along the push rack 10, so that the gap at the bottom of the push rack 10 is opened, and the impurities on the left side of the push rack 10 flow to the right along the gap, avoiding that some impurities are blocked on the left side when the push rack 10 returns.

[0047] like Fig.11As shown, a U-shaped bracket 22 is also included. The U-shaped bracket 22 is slidably connected to one side of the push frame 10 close to the magnetic stopper 21 along the up and down directions. The push frame 10 is fixedly connected to the magnetic stopper 21. An arc groove 221 is opened on the top of the U-shaped bracket 22. The arc groove 221 is used to limit the rotating plate 12 so that the rotating plate 12 cannot be rotated and opened.

[0048] When the magnetic stopper 21 moves downward, it drives the U-shaped bracket 22 to move downward, so that the arc groove 221 is disengaged from the rotating plate 12. When the magnetic stopper 21 moves upward, it drives the U-shaped bracket 22 to move upward, so that the arc groove 221 contacts the rotating plate 12 to limit the rotating plate 12. In this way, the push frame 10 can be rotated and opened when driving the rotating plate 12 to return from the far right to the left. When the push frame 10 drives the rotating plate 12 to move to the far left, the impurities on the left side of the push frame 10 can only flow to the right side along the gap and cannot flow out from the through hole. By closing the through hole at the rotating plate 12 and opening the gap, only one outlet is opened. Compared with opening two outlets, the closed area of ​​the push frame 10 is larger, so that the impurity solution between the push frame 10 and the left side of the inner wall of the filter frame 8 is subjected to a greater squeezing force, thereby making it easier to flow out to the right side of the push frame 10.

[0049] Embodiment 4: Based on embodiment 3, Fig.12 As shown, it also includes an adjusting plate 23 for adjusting the water pressure. The adjusting plate 23 is slidably connected to the water tank 4 on the right side along the up and down directions. The adjusting plate 23 is close to the water pipe 6. A screw 24 is threadedly connected to the water tank 4 on the right side, and the screw 24 is rotatably connected to the adjusting plate 23.

[0050] When the sewage in the dental water system pipeline is pumped into the water tank 4 on the right through the water pipe 6 on the right, the adjusting plate 23 is driven up and down by rotating the screw 24, so as to adjust the passage diameter between the right water pipe 6 and the right water tank 4. When the passage diameter is adjusted to a smaller size, the water pressure can be increased, and when the passage diameter is adjusted to a larger size, the water pressure can be adjusted to a smaller size. In this way, it can meet the actual use requirements of different water pressures of the dental water system.

[0051] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
