Description

Technical Field

[0001] The present invention relates to the technical field of oral irrigators, and particularly to a combined multi-nozzle oral irrigator. Background Technique

[0002] An oral irrigator is an oral cleaning device based on high-pressure water flow technology, aiming to efficiently clean the residues near the tooth gaps and gum lines, making up for the deficiencies of traditional toothbrushes and dental floss. Its core technologies include an efficient water pump, pulsed water flow adjustment, and intelligent induction. Combined with waterproof materials and ergonomic design, it ensures comfortable use and durability. With the increasing global awareness of oral health, oral irrigators have gradually developed from auxiliary tools recommended by dentists to essential daily care devices for families, especially suitable for users with sensitive gums, undergoing orthodontic treatment, or having dental implants. Its trend of being portable and intelligent has further expanded the market demand, providing users with a more comprehensive oral care experience.

[0003] During the use of an oral irrigator, clean water is stored in the housing. Then, the water in the water tank is pumped out and pressurized by a water pump to form a high-pressure water flow for cleaning the teeth and gum gaps. Moreover, during the use of the oral irrigator, the operator will also use a cleaning solution to rinse the teeth. However, most oral irrigators usually only have one water tank. Therefore, during the use of different liquids, the water tank needs to be taken out and replaced with other liquids, making the teeth cleaning process cumbersome. Therefore, it does not meet the existing requirements, and for this reason, we propose a combined multi-nozzle oral irrigator. Summary of the Invention

[0017] As an optional solution of a combined multi-nozzle water flosser described in the present invention, wherein: a groove is opened inside the placement slot, a limiting block is movably installed inside the groove, a connecting spring is installed between the limiting block and the groove, a limiting groove is opened on the bottom side of the placement slot, and the limiting block is engaged with the limiting groove.

[0018] The present invention has the following beneficial effects:

[0019] 1. The combined multi-nozzle water flosser, through the cooperation of the clamping column and the clamping groove, the operator rotates the clamping column in the process of switching different liquids. Since the clamping column and the clamping groove make the liquid storage box rotate at the same time, the positions of the first liquid storage chamber and the second liquid storage chamber are swapped, and the switching between clean water and cleaning liquid is realized; when the operator changes the liquid, there is no need to disassemble and install the liquid storage box, and the operator only needs to rotate the clamping column to switch the position of the liquid storage chamber and realize the use of different liquids;

[0020] Moreover, through the cooperation of the gear column and the elastic strip, after the liquid storage box is rotated, the end of the elastic strip will engage with the elastic strip, thereby locking the position of the liquid storage box, avoiding as much as possible the possibility of the liquid storage box shaking causing the liquid supply tube and the docking tube to fail to dock, thereby improving the liquid supply effect.

[0021] 2. The combined multi-nozzle water flosser cooperates with the support rod, the control box, the sliding block, the sliding column and the connecting groove. During the rotation of the liquid storage box, the control rod contacts the support rod, so that the support rod drives the sliding block to move upward. During the upward movement, the first rotating rod and the second rotating rod are rotated by utilizing the cooperation of the connecting groove and the sliding column, so that the two originally close flow limiting plates move away from each other, thereby achieving the blockage inside the butt tube, so that the two flow limiting plates block the liquid, and thus the water output of the cleaning liquid is reduced; through the rotation of the two flow limiting plates, excessive cleaning liquid is prevented from entering the oral cavity. At the same time, the reduction in water output allows the cleaning liquid to stay in the oral cavity for a longer time, thereby increasing the contact time of the cleaning liquid with the teeth and the oral surface, delaying the time for the cleaning liquid to overflow from the oral cavity, and also reducing the waste of the cleaning liquid, thereby improving the use efficiency.

[0022] 3. The combined multi-nozzle water flosser cooperates with the push rod, piston plate, push ball and connecting tube. During the rotation of the liquid storage box, the push rod contacts the push ball, causing the piston block to slide inside the connecting tube. Therefore, the piston block squeezes the gas inside the connecting tube during the movement. The squeezed gas reaches the inside of the connecting tube, blowing the inside of the connecting tube and spraying the residual liquid in the pump body through the nozzle, avoiding the water from flowing back into the liquid storage box as much as possible. Moreover, the discharge of the residual liquid can reduce the corrosion and deposition of the liquid inside the pump body and extend the service life of the equipment.

Detailed implementation manners

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below 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.

[0034] Embodiment 1. This embodiment aims to facilitate the solution of the problem that when using a dental irrigator, clear water will be stored in the housing. The water in the water tank is pumped out by a water pump and pressurized to form a high-pressure water flow for cleaning teeth and gum gaps. Moreover, during the use of the dental irrigator, the operator will also use a cleaning solution to rinse the teeth. However, most dental irrigators usually only have one water tank. Therefore, when using different liquids, the water tank needs to be taken out and replaced with other liquids, making the teeth cleaning process cumbersome. Please refer to Figures 1-9 , a combined multi-nozzle dental irrigator, including a dental irrigator housing 110 and electronic components 111 installed inside the dental irrigator housing 110. A liquid storage box 120 is rotatably installed inside the dental irrigator housing 110. The liquid storage box 120 internally includes a first liquid storage chamber 121 and a second liquid storage chamber 122. The first liquid storage chamber 121 is used for placing liquid. It should be noted that the liquid placed in the first liquid storage chamber 121 is clear water, and the second liquid storage chamber 122 is used for placing a cleaning solution. It should be noted that the liquid placed in the second liquid storage chamber 122 can be an antibacterial mouthwash or other oral care liquids, etc.

[0035] A spray pipe 123 and a docking pipe 124 are installed on the dental irrigator housing 110. Liquid supply pipes 125 are respectively installed inside the first liquid storage chamber 121 and the second liquid storage chamber 122. The spray pipe 123, the docking pipe 124, and the liquid supply pipes 125 are communicated. Two flow limiting plates 130 are rotatably installed inside the docking pipe 124. The two flow limiting plates 130 are used to adjust the liquid flow rate. A control box 140 for adjusting the rotation amplitude of the flow limiting plates 130 is installed on the side of the docking pipe 124. A control rod 112 for driving the control box 140 to operate is installed on the liquid storage box 120.

[0036] It should be noted that the electronic components 111 include a power management module, a motor driver, a sensor, a water pump, a control unit, and a user interface component, etc. It can pump out the water flow through the cooperation of the control unit and the water pump. Its specific model, working principle, and usage method are well known to those skilled in the art and will not be elaborated here.

[0037] Inside the dental irrigator housing 110, a placement groove 150 is provided. The liquid storage box 120 is detachably placed inside the placement groove 150. A first sealing ring 151 is installed on the upper side of the liquid storage box 120. The first sealing ring 151 is connected to the liquid supply pipe 125. Liquid supply balls 152 are respectively installed inside the first liquid storage cavity 121 and the second liquid storage cavity 122. The liquid supply balls 152 are made of steel. Liquid inlet openings 153 are provided on the surfaces of the liquid supply balls 152. The liquid supply balls 152 communicate with the liquid supply pipe 125. The liquid supply pipe 125 is a flexible pipe. A second sealing ring 154 is installed on the bottom side of the docking pipe 124. By fitting the second sealing ring 154 with the first sealing ring 151, the sealing performance between the liquid supply ball 152 and the liquid supply pipe 125 is improved.

[0038] See Figure 1 , Figure 2 and Figure 3 , specifically in implementation, a clamping groove 160 is provided on the bottom side of the liquid storage box 120. A clamping post 161 is rotatably installed on the bottom side of the dental irrigator housing 110. The end of the clamping post 161 is clamped inside the clamping groove 160. A driving groove 162 is provided on the inner wall of the dental irrigator housing 110. A gear post 163 is installed on the clamping post 161. The gear post 163 is located inside the driving groove 162. When the operator switches the cleaning liquid or clean water, the clamping post 161 is rotated. Since the clamping post 161 is clamped with the clamping groove 160 on the bottom side of the liquid storage box 120, the liquid storage box 120 is driven to rotate during the rotation process, so that the positions of the first liquid storage cavity 121 and the second liquid storage cavity 122 are swapped, and the docking pipe 124 is docked with the liquid supply pipe 125 again, realizing the switching of different liquids; moreover, through the cooperation of the liquid supply pipe 125, the docking pipe 124 and the electronic component 111, water is discharged from the dental irrigator housing 110.

[0039] See Figure 1 , Figure 2 , Figure 3 and Figure 4A push spring 164 is installed between the gear column 163 and the driving groove 162, and an elastic strip 165 is installed inside the driving groove 162, and the end of the elastic strip 165 is engaged with the gear column 163; in the process of rotating the engaging column 161, the gear column 163 is driven to rotate, so the teeth of the gear column 163 resist the elastic strip 165, and the elastic strip 165 is retracted under the force, so the elastic strip 165 and the gear column 163 are disengaged, so that the engaging column 161 smoothly drives the liquid storage box 120 to rotate; after the position of the liquid storage box 120 is adjusted, the gear column 16 3 is stationary, so that the end of the elastic strip 165 is no longer squeezed, so the elastic strip 165 is engaged with the gear column 163, thereby reducing the rotation of the engaging column 161, and also reducing the rotation of the liquid storage box 120, so that the liquid supply tube 125 and the docking tube 124 can be docked as much as possible. Moreover, when taking out the liquid storage box 120, the operator pulls the engaging column 161 downward, so that the engaging column 161 loses engagement with the engaging groove 160, thereby losing engagement with the liquid storage box 120, so that it is convenient for the operator to take out the liquid storage box 120 from the inside of the oral irrigator housing 110.

[0040] It should be noted that the liquid storage box 120 is provided with a water inlet for replenishing liquid.

[0041] In this embodiment: through the cooperation of the engaging column 161 and the engaging groove 160, the operator rotates the engaging column 161 during the process of switching different liquids. Due to the engagement of the engaging column 161 and the engaging groove 160, the liquid storage box 120 rotates at the same time, so that the positions of the first liquid storage chamber 121 and the second liquid storage chamber 122 are swapped, thereby realizing the switching between clean water and cleaning liquid. In this solution, when the operator changes the liquid, there is no need to perform the cumbersome actions of disassembling and installing the liquid storage box 120. Only the engaging column 161 needs to be rotated to switch the position of the liquid storage chamber and realize the use of different liquids.

[0042] Moreover, through the cooperation between the gear column 163 and the elastic strip 165, after the liquid storage box 120 is rotated, the end of the elastic strip 165 will engage with the elastic strip 165, thereby achieving the locking of the position of the liquid storage box 120, and avoiding as much as possible the possibility that the liquid storage box 120 shakes and causes the liquid supply tube 125 to not dock with the docking tube 124, thereby improving the liquid supply effect.

[0043] Embodiment 2: This embodiment is intended to promote the solution of the problem that the cost of cleaning liquid is higher than that of clean water. When the same liquid flow rate is used, it may lead to excessive waste of cleaning liquid. Moreover, many cleaning liquids need to have a certain contact time with the teeth. When the cleaning liquid flow rate is too much, the cost of waste is also too much. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figures 1-9A first rotating rod 170 and a second rotating rod 171 are rotatably installed inside the butt joint 124, and the second rotating rod 171 is rotatably fitted inside the first rotating rod 170. The two limiting plates 130 are respectively installed on the sides of the first rotating rod 170 and the second rotating rod 171. A driving block 172 is installed at the ends of the first rotating rod 170 and the second rotating rod 171, and a sliding column 173 is installed on the side of the driving block 172.

[0044] The control box 140 includes a sliding block 141 slidably installed inside the control box 140, a support rod 142 installed at the end of the sliding block 141, and a pulling spring 143 installed between the sliding block 141 and the control box 140. The support rod 142 is slidably plugged into the control box 140, and a sliding block 144 is symmetrically installed on the side of the sliding block 141. The inner wall of the control box 140 is symmetrically opened with a sliding groove 145, and the sliding block 144 is slidably matched with the sliding groove 145.

[0045] A horizontal plate 180 is installed in the middle of the sliding block 141, and a horizontal groove 181 is opened on the horizontal plate 180. Connecting grooves 182 are symmetrically opened on both sides of the horizontal groove 181. Two driving blocks 172 are movably matched on both sides of the horizontal plate 180, and the second rotating rod 171 is slidably matched with the horizontal groove 181. Two sliding posts 173 are movably matched with the two connecting grooves 182 respectively.

[0046] In specific implementation, when the liquid storage box 120 rotates, the control rod 112 rotates accordingly, so that the control rod 112 is located at the bottom side of the support rod 142, and the support rod 142 is resisted to move up. At this time, the support rod 142 drives the sliding block 141 to move up. In the process of sliding block 141 moving up, the movement of the connecting groove 182 is used to push and pull the two sliding columns 173. In the process of pushing and pulling, the two sliding columns 173 drive the first rotating rod 170 and the second rotating rod 171 to rotate, and in the process of rotation, the two originally close flow limiting plates 130 are moved away from each other, so that the liquid inside the connecting pipe 124 is blocked and the water output is reduced. Therefore, the water output of the cleaning liquid is reduced, thereby reducing the water output of the cleaning liquid. Due to the reduction in the water output of the cleaning liquid, the cleaning liquid can be in the oral cavity for a long time, reducing the time for the cleaning liquid to overflow from the oral cavity, so that the cleaning liquid has a certain contact time with the teeth.

[0047] In this embodiment: Through the cooperation of the support rod 142, the control box 140, the sliding block 141, the sliding column 173 and the connecting groove 182, during the process of rotating the liquid storage box 120, the control rod 112 abuts against the support rod 142. Therefore, the support rod 142 drives the sliding block 141 to move upward. During the upward movement, by using the cooperation of the connecting groove 182 and the sliding column 173, the first rotating rod 170 and the second rotating rod 171 rotate, so that the two originally adjacent current-limiting plates 130 move away from each other, thereby realizing the blockage inside the docking pipe 124, and the two current-limiting plates 130 block the liquid. Therefore, the water output of the cleaning liquid decreases; through the rotation of the two current-limiting plates 130, excessive cleaning liquid is prevented from entering the oral cavity. At the same time, the reduction in water output allows the cleaning liquid to stay in the oral cavity for a longer time, increasing the contact time between the cleaning liquid and the teeth and the oral surface, delaying the time when the cleaning liquid overflows from the oral cavity, reducing the waste of the cleaning liquid, and improving the use efficiency.

[0048] Embodiment 3. The purpose of this embodiment is to facilitate the solution of the problem that during the process of switching different liquids, the liquid remaining inside the pump body may flow back, affecting the water quality. This embodiment is an improvement made on the basis of Embodiment 2. Specifically, please refer to Figures 1-9 , a connecting pipe 190 is installed on the side of the docking pipe 124. The connecting pipe 190 communicates with the docking pipe 124, and a piston block 191 is installed inside the connecting pipe 190; an annular block 192 is installed on the inner wall of the connecting pipe 190. A return spring 193 is installed between the piston block 191 and the annular block 192. One end of the piston block 191 is installed with a connecting rod 194, and the end of the connecting rod 194 is installed with a pushing ball 195. A pushing rod 210 is installed on the liquid storage box 120, and a first one-way valve 211 is installed on the piston block 191. The first one-way valve 211 is used to introduce air into the connecting pipe 190. A second one-way valve 212 is installed at the connection between the connecting pipe 190 and the docking pipe 124. The second one-way valve 212 is used to blow air into the docking pipe 124 and prevent the liquid from flowing into the connecting pipe 190;

[0049] During specific implementation, during the rotation of the liquid storage box 120, the pushing rod 210 rotates with the liquid storage box 120. During the rotation, the pushing rod 210 abuts against the pushing ball 195, so that the pushing ball 195 drives the connecting rod 194 to move into the connecting pipe 190. During the movement, the piston plate is driven, so that the piston block 191 slides inside the connecting pipe 190. Therefore, during the movement of the piston block 191, the gas inside the connecting pipe 190 is compressed. Therefore, the compressed gas reaches the inside of the docking pipe 124, realizing blowing air into the docking pipe 124 and blowing out the liquid remaining inside the pump body through the spray pipe 123.

[0050] During specific implementation, an elastic sheet 220 is installed at the mouth of the liquid supply pipe 125. The elastic sheet 220 is used to prevent liquid from flowing out of the liquid storage box 120 as much as possible. The elastic sheet 220 is arranged in a fan shape. There are four elastic sheets 220. The four elastic sheets 220 are installed in a circular array at the mouth of the liquid supply pipe 125. When water flows through the elastic sheet 220, pressure is generated due to the water flow, and the elastic sheet 220 is squeezed, so that the end of the elastic sheet 220 is tilted. Therefore, a through hole is formed between the four elastic sheets 220, allowing the liquid to flow out. A third one-way valve 240 is installed at the butt joint pipe 124. The third one-way valve 240 is used to prevent liquid reflux.

[0051] A groove 230 is opened inside the placement groove 150, and a limit block 231 is movably installed inside the groove 230. A connecting spring 232 is installed between the limit block 231 and the groove 230. A limit groove 233 is opened on the bottom side of the placement groove 150, and the limit block 231 is engaged with the limit groove 233. The limit block 231 is set to an arc surface.

[0052] In specific implementation, during the rotation of the liquid storage box 120, the limit block 231 is squeezed by the shell of the liquid storage box 120 and retracts into the inside of the groove 230. When the liquid storage box 120 is rotated to the switching position, the limit groove 233 is aligned with the groove 230. At the same time, the limit block 231 loses its restriction and reaches the inside of the limit groove 233 by the push of the connecting spring 232, so that the operator can guide the position of the liquid storage box 120 when rotating it.

[0053] In this embodiment: through the cooperation of the push rod 210, the piston plate, the push ball 195 and the connecting tube 190, during the rotation of the liquid storage box 120, the push rod 210 resists the push ball 195, so that the piston block 191 slides inside the connecting tube 190. Therefore, the piston block 191 squeezes the gas inside the connecting tube 190 during the movement, so that the squeezed gas reaches the inside of the docking tube 124, realizes blowing inside the docking tube 124, and sprays the residual liquid in the pump body through the nozzle 123, so as to avoid the water flow back to the liquid storage box 120 as much as possible. Moreover, the discharge of the residual liquid can reduce the corrosion and deposition of the liquid inside the pump body, thereby extending the service life of the equipment.

[0054] It should be noted that in this text, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
