Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a disinfection cabinet for oral instruments. Background Art

[0002] Oral instruments play an important role in dental treatment. These instruments include probes, curettes, extraction forceps, dental forceps, dental hammers and chisels, root canal files, dental spatulas, etc. Since oral instruments directly contact the oral tissues of patients, strict disinfection procedures must be carried out to kill possible pathogenic microorganisms to ensure the safety and health of patients.

[0003] Oral instrument disinfection cabinets are mainly divided into ultraviolet disinfection cabinets, ozone disinfection cabinets, and high-temperature steam disinfection cabinets according to different disinfection principles. Among them, high-temperature steam disinfection cabinets use the bactericidal effect of high-temperature steam to disinfect oral instruments at high temperature and high pressure, and have the advantages of reliable disinfection effect and wide application range. However, attention needs to be paid to the temperature and pressure of the steam, as well as the high-temperature resistance performance of the instruments.

[0004] When disinfecting oral instruments, it is necessary to first clean the oral instruments to be disinfected, remove the stains and residues on the surface, then place them in the disinfection cabinet according to the specified placement positions, and then select a suitable disinfection procedure according to the type of the disinfection cabinet and the material of the oral instruments. For example, for an ultraviolet disinfection cabinet, an appropriate irradiation time and intensity can be selected; for an ozone disinfection cabinet, an appropriate ozone concentration and disinfection time can be selected; for a high-temperature steam disinfection cabinet, an appropriate temperature and pressure can be selected. Then, turn on the power supply, press the power-on button to start the disinfection procedure. Finally, after the disinfection is completed, it is necessary to wait for the disinfection cabinet to cool down before taking out the instruments. When taking out the instruments, personal protection needs to be paid attention to, and protective supplies such as gloves should be worn to avoid direct contact with high temperature or harmful gases.

[0005] Currently, when disinfecting oral instruments in the prior art, it is usually necessary to first soak the oral instruments in a cleaning agent to clean the surface dirt, then rinse with running water, and finally perform pressure steam sterilization. However, soaking, rinsing, and sterilization need to be operated by personnel in different devices respectively, and it is necessary to manually transfer the oral instruments multiple times, which is time-consuming and laborious, thus easily affecting the disinfection efficiency of oral instruments. Therefore, it does not meet the existing requirements, and for this reason, we propose a disinfection cabinet for oral instruments. Summary of the Invention

Detailed implementation manners

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] Embodiment 1. The purpose of this embodiment is to facilitate the solution of the problem that when disinfecting oral instruments in the prior art, it is usually necessary to first soak the oral instruments in a cleaning agent to clean the surface dirt, then rinse with flowing water, and finally perform pressure steam sterilization. However, soaking, rinsing, and sterilization need to be operated by personnel in different devices respectively, and it is necessary to manually transfer the oral instruments multiple times, which is time-consuming and laborious, thus easily affecting the disinfection efficiency of oral instruments. Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 9 、 Figure 11 、 Figure 12 and Figure 13 A disinfection cabinet for oral instruments, comprising a cabinet body 100, a water inlet pipe 110, a water outlet pipe 120, and a steam pipe 130 connected to the side of the cabinet body 100. A cabinet door 101 is rotatably arranged outside the cabinet body 100. The number of the cabinet doors 101 is set to two, and both cabinet doors 101 are arranged in the upper half of the cabinet body 100, facilitating the opening and closing of the upper part of the cabinet body 100. The lower half of the cabinet body 100 is set to be enclosed, facilitating the soaking of oral instruments at the bottom of the cabinet body 100. The water inlet pipe 110 is connected to clean water.

[0042] See Figure 2 and Figure 9 Inside the cabinet body 100, a basket 140 for placing oral instruments is slidably arranged. The basket 140 is set as a grid basket body, facilitating soaking and water leakage. Four sliders 141 are fixedly installed on the outside of the basket 140, respectively located around the basket 140. A chute 142 for cooperating with the slider 141 is opened on the inner wall of the cabinet body 100. The slider 141 is slidably inserted into the chute 142, and the slider 141 can slide out of the chute 142 through the transverse groove at the top of the chute 142, thus facilitating the removal of the basket 140 from the cabinet body 100.

[0043] See Figure 1 and Figure 13, a hook 143 is slidably arranged on the inner wall of the cabinet body 100. The hook 143 is arranged in a "U"-shaped rod shape. A clamping groove 144 is formed on the side of one of the sliders 141, and the hook 143 is inserted into the clamping groove 144. A traction rope 145 is fixedly connected to the upper end of the hook 143. A winch 146 is fixedly installed on the top of the cabinet body 100. The middle part of the traction rope 145 penetrates through the top of the cabinet body 100, so that the end of the traction rope 145 is connected to the winding end of the winch 146. The winch 146 is a technical means well-known to those skilled in the art and will not be elaborated here.

[0044] See Figure 1 , Figure 3 , Figure 4 and Figure 7 , a valve housing 150 is fixedly installed at the end of the water inlet pipe 110. A regulating valve 151 is rotatably arranged inside the valve housing 150. A communication hole 152 is formed on the side of the regulating valve 151. The communication hole 152 is arranged in an "L" shape, and one end of the communication hole 152 is located at the midpoint of the regulating valve 151, and the other end of the communication hole 152 is located on the side of the regulating valve 151. The end of the water inlet pipe 110 located inside the valve housing 150 is rotatably inserted into the midpoint of the regulating valve 151 and is communicated with one end of the communication hole 152. An immersion pipe 160 and a flushing pipe 170 are inserted into the side of the valve housing 150. The immersion pipe 160 and the flushing pipe 170 are both press-fitted into the side wall of the cabinet body 100, and the other end of the communication hole 152 is alternately communicated with the immersion pipe 160 and the flushing pipe 170.

[0045] See Figure 11 and Figure 12 , the immersion pipe 160 is communicated with the inner cavity of the cabinet body 100. A spray pipe 180 is slidably arranged inside the cabinet body 100. The flushing pipe 170 is communicated with the spray pipe 180. The number of the spray pipes 180 is set to two, and nozzles 181 are evenly arranged on the sides of the two spray pipes 180. A first lead screw 182 is rotatably arranged on the inner wall of the cabinet body 100 through a bearing. A first lead screw nut 183 is threadedly connected to the outside of the first lead screw 182. The number of the first lead screw nuts 183 is set to two. The first lead screw 182 is a bidirectional lead screw, and the two first lead screw nuts 183 are respectively arranged on the reverse threads of the first lead screw 182. One end of each of the two spray pipes 180 is fixedly connected to one of the two first lead screw nuts 183. A corrugated pipe 184 is arranged on the inner wall of the cabinet body 100. The corrugated pipe 184 can be extended or shortened. The two ends of the corrugated pipe 184 are respectively communicated with the other ends of the two spray pipes 180. The middle part of the corrugated pipe 184 is communicated with the flushing pipe 170.

[0046] A first gear 185 is rotatably provided on the inner wall of the cabinet 100, and a first rack 186 is fixedly installed on the outer side of the basket 140. The first rack 186 is loosely meshed with the first gear 185. Pulleys 187 are fixedly provided in the middle of the first screw rod 182 and on the side of the first gear 185, respectively. The pulley 187 located on the side of the first gear 185 is coaxially arranged with the first gear 185, and a belt 188 is commonly sleeved between the two pulleys 187.

[0047] In this embodiment, the oral instruments are placed in the basket 140, and the winch 146 unwinds the traction rope 145 to drive the basket 140 to rise and fall. The basket 140 carrying the oral instruments descends under the action of gravity. During this process, the basket 140 first descends to the lower end of the spray pipe 180 through the gap between the two spray pipes 180. Subsequently, the first rack 186 engages with the first gear 185, so that the first gear 185 drives the pulley 187 on its side to rotate. Then, the two pulleys 187 cooperate with the belt 188 to rotate the first screw rod 182. The first screw rod 182 cooperates with the first wire sleeve 183 to make the two first wire sleeves 183 approach each other, thereby driving the two spray pipes 180 to approach each other and be located above the basket 140, and the basket 140 descends to the bottom of the cabinet 100.

[0048] The regulating valve 151 is turned to connect the water inlet pipe 110 with the soaking pipe 160 through the connecting hole 152, so that the cleaning liquid enters the bottom of the cabinet 100 and soaks and cleans the oral instruments in the basket 140. After soaking, the cleaning liquid is discharged through the outlet pipe 120. The regulating valve 151 is turned again to connect the water inlet pipe 110 with the spray pipe 180 through the connecting hole 152, so that clean water is sprayed on the oral instruments through the nozzle 181 on the spray pipe 180 to rinse the residual cleaning liquid thereon. Finally, the basket 140 carries the oral instruments up to the upper end of the cabinet 100 and is discharged through the steam pipe 130. Oral instruments are sterilized by spraying high-temperature and high-pressure steam. In summary, the soaking, rinsing and steam sterilization of oral instruments are centralized and integrated, and the manual operation and transfer process are reduced, thereby improving the efficiency of oral instrument disinfection, and solving as much as possible the problem that when the existing technology is used to disinfect oral instruments, the oral instruments usually need to be soaked in a cleaning agent to clean the surface dirt, then rinsed with running water, and finally sterilized with pressure steam. However, the soaking, rinsing and sterilization require personnel to operate in different equipment respectively, and the oral instruments need to be manually transferred multiple times, which is time-consuming and labor-intensive, and thus easily affects the efficiency of oral instrument disinfection.

[0049] Embodiment 2. This embodiment aims to further facilitate the injection of cleaning liquid or clear water into the cabinet body 100 in a timely manner, which is not convenient for quickly soaking and rinsing oral instruments, thus easily affecting the disinfection efficiency of oral instruments.

Limiting blocks 213 are fixedly installed on the inclined surfaces on both sides of the first wedge block 211. Limiting grooves 214 for cooperating with the limiting blocks 213 are formed on the inclined surfaces of the two second wedge blocks 212. The two limiting blocks 213 are respectively slidably inserted into the two limiting grooves 214.

[0052] A threaded rod 215 is rotatably inserted into the side of the first wedge block 211. A rotating cylinder 216 is rotatably inserted into the outside of the housing 210. The middle part of the threaded rod 215 is commonly inserted into the sides of the housing 210 and the rotating cylinder 216, and the end of the threaded rod 215 is threadedly connected to the inside of the rotating cylinder 216. Clamping pieces 217 are installed on the outside of both second wedge blocks 212. Both clamping pieces 217 are arranged as arc-shaped pieces. The two clamping pieces 217 are closed to form a ring. Both clamping pieces 217 intermittently abut against the shaft rod 193, and the two clamping pieces 217 are respectively located on both sides of the shaft rod 193. In the initial state, a gap is left between both clamping pieces 217 and the shaft rod 193.

One end of the plug shaft 221 located outside the valve housing 150 is fixedly installed with a third gear 222. The third gear 222 meshes with the second gear 220.

[0054] In this embodiment: the water flow in the cavity tube 190 drives the impeller 191 to rotate. Through the meshing of the first bevel gear 192 and the second bevel gear 194, the shaft rod 193 and the third bevel gear 195 are driven to rotate. Through the meshing of the third bevel gear 195 and the fourth bevel gear 199, the rotating shaft 197 drives the feeding screw to rotate in the packing tube 196, so as to slowly and evenly put the enzyme filled therein into the soaking tube 160, and mix it with the clear water flowing through the soaking tube 160 to prepare a multi-enzyme cleaning solution and inject it into the cabinet 100. Moreover, the faster the water flow rate, the faster the feeding screw 198 rotates, so that the amount of added enzyme increases with the increase of the water flow rate, so that the enzyme and the clear water are prepared into a cleaning solution with a suitable concentration according to a certain ratio;

[0055] After the soaking is completed, the cleaning liquid is discharged from the water outlet pipe 120. Hold the rotating cylinder 216 and rotate it. Through the meshing of the second gear 220 and the third gear 222, the third gear 222 drives the regulating valve 151 to rotate through the insertion shaft 221, so that the end of the communication hole 152 is communicated with the flushing pipe 170, and the soaking pipe 160 is closed. At the same time, through the cooperation of the rotating cylinder 216 and the threaded rod 215, the threaded rod 215 pulls the first wedge block 211 to move backward. Through the cooperation of the first wedge block 211 and the two second wedge blocks 212, the two second wedge blocks 212 drive the two clamping pieces 217 to approach each other to clamp and fix the shaft rod 193, avoiding the rotation of the shaft rod 193 and making the feeding screw 198 stationary. Thus, clean water is injected into the spray pipe 180 through the flushing pipe 170, and the oral instruments are sprayed and rinsed through the nozzles 181. In summary, it is convenient to inject the cleaning liquid or clean water into the cabinet 100 in a timely manner, which is convenient for quickly soaking and rinsing the oral instruments, thereby further improving the disinfection efficiency of the oral instruments.

[0056] Embodiment 3. The purpose of this embodiment is to promote the solution of the problem that the high-temperature and high-pressure steam ejected from the steam pipe 130 is diffused in the inner cavity of the entire cabinet 100, which is likely to cause insufficient steam temperature and pressure, thus easily affecting the disinfection effect of oral instruments. This embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figure 1 , Figure 2 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 , a second screw rod 230 is also rotatably arranged on the inner wall of the cabinet 100. The second screw rod 230 is the same as the first screw rod 182. Similarly, two second screw sleeves 231 are respectively threadedly connected to the outside of the second screw rod 230. Support rods 232 are fixedly installed on the outside of the two second screw sleeves 231. The ends of the support rods 232 are slidably inserted into the inner wall of the cabinet 100. Partition plates 233 are arranged between the inner wall of the cabinet 100 and the adjacent support rods 232. The partition plates 233 are all set as accordion-style folding and telescopic plates, that is, similar to the accordion plate of a folding fan. A flat thin plate is repeatedly folded to form it, and it can be stretched and compressed. The accordion plate is a multifunctional plate with multiple properties such as sound insulation, sealing, fire prevention, and expansion and contraction. The accordion plate is a commonly used existing technology product and will not be elaborated here. One end of the partition plate 233 is fixedly connected to the inner wall of the cabinet 100, and the other end of the partition plate 233 is fixedly connected to the support rod 232.

[0057] See Figure 9 and Figure 10When the basket 140 is located above the baffle plate 233, the two support rods 232 approach each other and collide with each other, expanding the baffle plate 233 so that the baffle plate 233 divides the space inside the cabinet 100 into two independent spaces, the steam inlet end of the steam pipe 130 is connected to the upper part of the cabinet 100; when the basket 140 is located below the baffle plate 233 and the spray pipe 180, the two support rods 232 move away from each other and retract into the inner wall of the cabinet 100, compressing the baffle plate 233 and releasing the separation effect of the baffle plate 233. The end of the flushing pipe 170 is connected to the lower part of the cabinet 100, and the water outlet pipe 120 is connected to the bottom of the cabinet 100.

[0058] See Figure 13 A fourth gear 234 is fixedly installed at the end of the second screw rod 230, and a second rack 235 is fixedly installed on the outside of the hook 143. The second rack 235 is intermittently meshed with the fourth gear 234. A slide 236 is fixedly installed on the outside of the first wire sleeve 183 and the second wire sleeve 231. A groove body for use with the slide 236 is opened on the inside of the cabinet 100, and the slide 236 is slidably inserted into the groove body on the inside of the cabinet 100.

[0059] In this embodiment, when the hook 143 descends along with the basket 140 and the slider 141, the hook 143 drives the second rack 235 to descend close to the fourth gear 234. Subsequently, the second rack 235 and the fourth gear 234 begin to mesh. At the same time, a sufficient distance is maintained between the bottom of the basket 140 and the blocking plate 233. The meshing of the second rack 235 and the fourth gear 234 drives the second screw rod 230 to rotate. The cooperation between the second screw rod 230 and the second screw sleeve 231 causes the second screw sleeve 231 to drive the support rods 232 away from each other, thereby causing the blocking plate 233 to retract into the side wall of the cabinet 100, thereby avoiding obstruction to the descent of the basket 140.

[0060] When the basket 140 rises from the bottom of the cabinet 100, similarly to the above, the second rack 235 and the fourth gear 234 are meshed again, and the second screw rod 230 and the second screw sleeve 231 are used in conjunction with each other, so that the blocking plate 233 is deployed. When the basket 140 is located in the upper part of the cabinet 100, the blocking plate 233 separates the cabinet 100 into two independent spaces, upper and lower. The high-temperature and high-pressure steam ejected from the steam pipe 130 is concentrated in the upper inner cavity of the cabinet 100, so that the steam maintains sufficient temperature and pressure, thereby improving the disinfection effect of the oral instruments in the basket 140.
