[0049] Please refer to Figure 1 , Figure 2 and Figure 3 , the embodiment provides a dental treatment chair with equipment disinfection function, which comprises a disinfection cylinder 10, a storage cylinder 20, a containing plate 30, a spraying assembly 40, a first driving assembly 50 and a second driving assembly 60. The disinfection cylinder 10 is installed on the side or bottom of the dental treatment chair. The storage cylinder 20 is rotatably arranged in the disinfection cylinder 10. The containing plate 30 is provided with two groups, and the two groups of containing plates 30 are arranged on the inner side of the storage cylinder 20 and are distributed oppositely. The spraying assembly 40 is arranged on the inner side of the storage cylinder 20, and is used for spraying disinfectant to the containing plate 30 located below. The first driving assembly 50 is arranged in the disinfection cylinder 10, and is used for driving the two groups of containing plates 30 to move away from each other and move close to each other. When the two groups of containing plates 30 move close to each other, the treatment equipment can be clamped. The second driving assembly 60 is installed at the end of the disinfection cylinder 10. After the two groups of containing plates 30 move close to each other to clamp the treatment equipment, the second driving assembly 60 is used to drive the storage cylinder 20 and the two groups of containing plates 30 to rotate 180°.
[0050] At the beginning, the two groups of holding plates 30 are spaced apart in the storage barrel 20. When the dental treatment equipment needs to be disinfected, the equipment is placed on the upper part of the lower group of holding plates 30, and then the spraying assembly 40 sprays disinfectant liquid to the lower group of holding plates 30. The disinfectant liquid acts on the upper surface of the treatment equipment, and the upper surface of the treatment equipment is disinfected. After a certain time of disinfection, the first driving assembly 50 drives the two groups of holding plates 30 to move close to each other. When the two groups of holding plates 30 move close to each other, the treatment equipment is clamped. Then, the second driving assembly 60 drives the storage barrel 20 and the two groups of holding plates 30 to rotate 180°. The treatment equipment clamped between the two groups of holding plates 30 is turned over 180°. At this time, the holding plate 30 originally located below is rotated to the upper position, and the holding plate 30 originally located above is rotated to the lower position. Then, the first driving assembly 50 drives the two groups of holding plates 30 to move away from each other. The treatment equipment turned over 180° falls onto the upper part of the lower group of holding plates 30 and moves downward with the lower group of holding plates 30. The original lower surface of the treatment equipment is adjusted to the upper surface. The spraying assembly 40 continues to spray disinfectant liquid to the lower group of holding plates 30. The disinfectant liquid acts on the lower surface of the treatment equipment, and the lower surface of the treatment equipment is disinfected. In this way, the treatment equipment can be fully and automatically disinfected, avoiding disinfection dead angles and improving the disinfection effect of the treatment equipment. Since the disinfection barrel 10 is installed on the side or bottom of the dental treatment chair, the treatment equipment can be disinfected in time after the patient is treated, and the disinfected treatment equipment can be used in time, thereby improving the convenience of disinfection and use of the treatment equipment.
[0051] Please refer to Figure 1 , Figure 2 and Figure 3 In one embodiment, the disinfection barrel 10 is provided with a liquid discharge pipe 102 at the bottom. The storage barrel 20 includes an end plate 201 and a side plate 202. The side plate 202 is provided in two groups, and the two groups of side plates 202 are fixedly arranged on one side of the end plate 201 and are oppositely distributed. The two groups of holding plates 30 are the same in structure and each include a holding plate 301. The two groups of holding plates 301 are arranged between the two groups of side plates 202 and are oppositely distributed. A plurality of uniformly distributed through holes 3011 are formed in the two groups of holding plates 301.
[0052] When the dental treatment equipment needs to be disinfected, the equipment is placed on the upper part of the lower set of holding plates 301, and then the spraying assembly 40 sprays disinfectant downward to the lower holding plates 301, which acts on the upper surface of the treatment equipment to disinfect the upper surface of the treatment equipment. When the upper surface of the treatment equipment is disinfected for a certain period of time, the first drive assembly 50 drives the two sets of holding plates 301 to move closer to each other to clamp the treatment equipment, and then the second drive assembly 60 drives the end plate 201, the two sets of side plates 202, the two sets of holding plates 301, and the treatment equipment clamped by the two sets of holding plates 301 to rotate 180°, and then the first drive assembly 50 drives the two sets of holding plates 301 to move away from each other, and the lower surface of the treatment equipment after being turned over 180° is adjusted to face upward, so as to be disinfected by the subsequent sprayed disinfectant. After the spraying assembly 40 sprays disinfectant to act on the treatment equipment, the disinfectant can pass through the plurality of through holes 3011 on the holding plate 301 and act on the inner bottom of the disinfection cylinder 10, and then be discharged by the drain pipe 102.
[0053] Please refer to Figure 2 、 Figure 3 and Figure 4 In one embodiment, the first drive assembly 50 includes a rope body 501 and a winding drum 502, the winding drum 502 is rotatably installed on the side wall of the end plate 201, the rope body 501 is provided in two sets, one end of the two sets of rope bodies 501 is connected with the winding drum 502, and the other end is respectively connected with one set of holding plates 301, the side wall of the end plate 201 is fixedly provided with a fixed plate 203, the fixed plate 203 is provided in two sets, the two sets of fixed plates 203 are respectively arranged on the opposite sides of the winding drum 502, the second drive assembly 60 includes a transmission gear 601, a support pipe 602, an incomplete gear 603 and a motor 604, the motor 604 is fixedly arranged on the outer wall of the disinfection cylinder 10, the incomplete gear 603 is installed on the output end of the motor 604, one end of the support pipe 602 extends to the outside of the disinfection cylinder 10, the other end penetrates the side wall of the disinfection cylinder 10 and the end plate 201 and is connected with the winding drum 502, and the transmission gear 601 is fixedly arranged outside the support pipe 602 and can be engaged with the incomplete gear 603.
[0054] After the surface of the treatment device is sterilized for a certain period of time, the motor 604 drives the incomplete gear 603 to rotate. When the incomplete gear 603 rotates, it meshes with the transmission gear 601, thereby driving the support pipe 602 to rotate. When the support pipe 602 rotates, it drives the winding drum 502 to rotate. When the winding drum 502 rotates, it first winds the two groups of ropes 501, so that the two groups of ropes 501 pull the two groups of holding plates 301 to approach each other. When the two groups of holding plates 301 clamp the treatment device, since the two groups of holding plates 301 no longer approach each other, the incomplete gear 603 continues to mesh with the transmission gear 601, thereby driving the support pipe 602 and the winding drum 502 to continue to rotate. When the winding drum 502 continues to rotate, it drives the end plate 201, the two groups of side plates 202, the two groups of holding plates 301, and the treatment device clamped by the two groups of holding plates 301 to rotate as a whole. When the two groups of holding plates 301 and the treatment device rotate 180°, the incomplete gear 603 disengages from the transmission gear 601.
[0055] Please refer to Figure 2 and Figure 7 In one embodiment, the two groups of fixing plates 203 and the two groups of holding plates 301 are connected by the first elastic members 205. The two groups of first elastic members 205 are used to provide elastic support to the two groups of holding plates 301, respectively. The ring plate 104 is fixedly arranged on the outer wall of the sterilization cylinder 10 and surrounds the outside of the support pipe 602. The ring plate 104 and the support pipe 602 are connected by the elastic return member 105.
[0056] When the incomplete gear 603 meshes with the transmission gear 601 and drives the support pipe 602 and the winding drum 502 to rotate, the elastic return member 105 is tightened and stores energy. When the winding drum 502 rotates and winds the two groups of ropes 501 to pull the two groups of holding plates 301 to approach each other, the two groups of first elastic members 205 are compressed under stress. When the incomplete gear 603 disengages from the transmission gear 601, the elastic return member 105 drives the support pipe 602 to rotate in the opposite direction, thereby driving the winding drum 502 to rotate in the opposite direction. When the winding drum 502 rotates in the opposite direction, it unwinds the two groups of ropes 501. In combination with the elastic support of the two groups of first elastic members 205 to the two groups of holding plates 301, the two groups of holding plates 301 move away from each other. At this time, the treatment device is turned over by 180°, so that the originally downward lower surface of the treatment device is rotated to the upward position, thereby being sterilized by the subsequent sterilizing liquid.
[0057] Please refer to Figure 2 and Figure 4In one embodiment, two groups of guide rails 204 are fixedly arranged on the side walls of the end plate 201, and two groups of the containing plates 301 are respectively slidably matched with the two groups of guide rails 204, so that the two groups of containing plates 301 can stably approach under the pulling of the two groups of rope bodies 501 and can stably move away under the pushing of the two groups of first elastic members 205.
[0058] Please refer to Figure 3 , and Figure 4 In one embodiment, the spraying assembly 40 comprises a U-shaped spraying pipe 401, a spray head 402, and a liquid conveying pipe 403. The U-shaped spraying pipe 401 is fixedly installed on the inner walls of the two groups of side plates 202. One end of the liquid conveying pipe 403 is rotatably connected with the winding drum 503 and communicates with the inner cavity of the winding drum 503, and the other end is fixedly connected with the U-shaped spraying pipe 401 and communicates with the inner cavity of the U-shaped spraying pipe 401. The spray head 402 is provided in several groups, and the several spray heads 402 are installed on the side walls of the U-shaped spraying pipe 401 and are distributed along the length direction of the U-shaped spraying pipe 401.
[0059] After the treatment device is placed on the upper part of the containing plate 301 located below, the disinfectant is pumped from the supporting pipe 602 to the inside of the winding drum 503 by an external pumping mechanism (not shown in the figure), and then sequentially enters the U-shaped spraying pipe 401 through the winding drum 503 and the liquid conveying pipe 403, and finally is sprayed out by the several spray heads 402, so as to act on the upper surface of the treatment device to disinfect the upper surface of the treatment device. Similarly, after the treatment device is turned over by 180°, the disinfectant sprayed out by the several spray heads 402 can act on the lower surface of the treatment device which has not been disinfected, so as to realize the comprehensive disinfection of the treatment device.
[0060] Please refer to Figure 2 , Figure 4 and Figure 6 In one embodiment, a group of containing main pipes 302 is fixedly arranged at the position of the opposite side edges of the two groups of containing plates 301. The side walls of the containing main pipes 302 are fixedly and continuously provided with several containing branch pipes 304 which are spaced apart along the length direction. The several containing branch pipes 304 are horizontally arranged on the containing surface of the containing plate 301 for supporting the treatment device. Each group of containing branch pipes 304 is covered with an annular air bag 303. Each group of containing branch pipes 304 is provided with several air holes 305 on the side walls. Two groups of air supply assemblies are arranged on the two groups of fixed plates 203. When the two groups of containing plates 301 approach each other, the two groups of air supply assemblies are used to respectively supply air into the interiors of the two groups of containing main pipes 302.
[0061] By placing the treatment equipment to be disinfected on the upper part of the plurality of annular air bags 303 located below, the upper surface of the treatment equipment to be treated is disinfected for a certain period of time. After that, the motor 604 drives the incomplete gear 603 to rotate, and in turn drives the support pipe 602 and the winding drum 502 to rotate. The winding drum 502 winds the two groups of rope bodies 501, and the two groups of rope bodies 501 pull the two groups of containing plates 301 close to each other. When the two groups of containing plates 301 are close to each other, the two groups of air supply assemblies supply air into the interiors of the two groups of containing main pipes 302. The air enters the interiors of the containing main pipes 302, and then enters the interiors of the plurality of containing branch pipes 304 and is delivered to the interiors of the plurality of annular air bags 303 through the air holes 305. In turn, the annular air bags 303 are inflated, and the annular air bags 303 are flexible clamped for treatment equipment of different volumes and thicknesses. Thus, the clamping effect of the treatment equipment is improved, and the treatment equipment is prevented from shaking and moving during the subsequent overturning process, thereby preventing the treatment equipment from being worn and improving the protection of the treatment equipment during the disinfection process.
[0062] Please refer to Figure 4 In one embodiment, the two groups of air supply assemblies are identical in structure and each include a pressing rod 206, a second elastic member 207, a piston cylinder 208, and a flexible pipe 209. The piston cylinder 208 is fixedly arranged on the side wall of the fixed plate 203. One end of the pressing rod 206 extends into the interior of the piston cylinder 208 and is telescopically connected with the piston cylinder 208, and the other end extends to the exterior of the piston cylinder 208. An annular stopper is fixedly arranged on the rod body of the pressing rod 206 outside the piston cylinder 208. One end of the second elastic member 207 is connected with the annular stopper, and the other end is connected with the piston cylinder 208, for providing elastic support for the pressing rod 206. One end of the flexible pipe 209 is in communication with the piston cylinder 208, and the other end is in communication with the containing main pipe 302.
[0063] When the two groups of containing plates 301 move close to each other, the two groups of containing plates 301 press the corresponding pressure rods 206 of the two groups of air supply assemblies, and then drive the pressure rods 206 to move to the inside of the corresponding piston pipes 208, so as to press the air in the piston pipes 208 to the inside of the corresponding containing main pipes 302 through the corresponding flexible pipes 209, and then into the inside of the containing branch pipes 304 through the containing main pipes 302, and finally into the inside of the annular air bags 303 through the air holes 305, so that the annular air bags 303 expand, and then flexibly clamp the treatment equipment; when the two groups of containing plates 301 and the clamped treatment equipment are turned over by 180°, with the two groups of first elastic members 205 pushing the two groups of containing plates 301 away from each other, the second elastic members 207 push the corresponding annular blocks and then drive the corresponding pressure rods 206 to move to the outside of the corresponding piston pipes 208, so as to extract the air in the annular air bags 303 to the inside of the containing branch pipes 304 through the air holes 305, and then to the inside of the piston pipes 208 through the containing branch pipes 304, the containing main pipes 302 and the flexible pipes 209, so that the annular air bags 303 deflate and reset, and the deflated and reset annular air bags 303 are attached to the outside of the containing branch pipes 304, so that there is a certain gap between the two adjacent annular air bags 303, so that the disinfectant can flow into the upper part of the containing plate 301 between the two adjacent annular air bags 303 after disinfecting the treatment equipment, and then flow into the inside bottom of the disinfection cylinder 10 through the through hole 3011, and finally be discharged from the liquid discharge pipe 102.

[0070] When disinfection is needed, the sealing door can be opened to place the treatment equipment to be disinfected on the upper part of the holding plate 301 located below from the taking and placing opening 101, and then the sealing door is closed. After disinfection is completed, the sealing door is opened again, and then the disinfected treatment equipment is taken out from the taking and placing opening 101.
[0071] In the embodiment of the application, initially, the two groups of holding plate members 30 are spaced apart and distributed in the storage cylinder 20. When the dental treatment equipment needs to be disinfected, the related equipment is placed on the upper part of the holding plate member 30 located below, and then the spraying assembly 40 sprays the disinfectant to the direction of the holding plate member 30 located below. The disinfectant acts on the upper surface of the treatment equipment, and then the upper surface of the treatment equipment is disinfected. After the upper surface of the treatment equipment is disinfected for a certain period of time, the first driving assembly 50 drives the two groups of holding plate members 30 to approach each other. When the two groups of holding plate members 30 approach each other, the treatment equipment is clamped. Then, the second driving assembly 60 drives the storage cylinder 20 and the two groups of holding plate members 30 to rotate 180°. The treatment equipment clamped between the two groups of holding plate members 30 is turned over by 180°. At this time, the holding plate member 30 originally located below is rotated to the upper position, and the holding plate member 30 originally located above is rotated to the lower position. Then, the first driving assembly 50 drives the two groups of holding plate members 30 to move away from each other. The treatment equipment turned over by 180° falls onto the upper part of the holding plate member 30 located below and moves downward with the holding plate member 30 located below. The original lower surface of the treatment equipment is adjusted to the upper surface. The spraying assembly 40 continues to spray the disinfectant to the direction of the holding plate member 30 located below. The disinfectant acts on the lower surface of the treatment equipment, and then the lower surface of the treatment equipment is disinfected. In this way, the treatment equipment can be fully and automatically disinfected, the disinfection dead angle can be avoided, and the disinfection effect of the treatment equipment can be improved. Since the disinfection cylinder 10 is installed on the side or the bottom of the dental treatment chair, after the dental treatment of the patient is completed, the related treatment equipment can be disinfected in time, and the disinfected treatment equipment can be used in time, thereby improving the convenience of disinfection and use of the treatment equipment. Compared with the prior art, when the dental treatment equipment is disinfected, the disinfection dead angle can be effectively avoided, the treatment equipment can be fully and automatically disinfected, and the disinfection effect is good and the disinfection efficiency is high.
