Description

Technical Field

[0001] The invention relates to the technical field of oral irrigators, and in particular to a combined multi-nozzle oral irrigator. Background Art

[0002] The water flosser is an oral cleaning device based on high-pressure water flow technology, designed to efficiently clean the residues between teeth and near the gum line, making up for the shortcomings of traditional toothbrushes and dental floss. Its core technologies include efficient water pumps, pulse water flow regulation and intelligent sensing, combined with waterproof materials and ergonomic design to ensure comfortable and durable use. With the improvement of global oral health awareness, the water flosser has gradually developed from an auxiliary tool recommended by dentists to a daily care device that is essential for families, especially for users with sensitive gums, orthodontics or dental implants. Its portability and intelligence trends have also further expanded market demand, providing users with a more comprehensive oral care experience.

[0003] During use, the water in the water tank is stored in the shell, and the water in the water tank is pumped out and pressurized by a water pump to form a high-pressure water flow for cleaning teeth and gum gaps. In addition, during the use of the water tank, the operator also uses a cleaning liquid to rinse the teeth. However, most water tanks are usually only equipped with one water tank. Therefore, when using different liquids, the water tank needs to be taken out and replaced with other liquids, making the teeth washing process cumbersome. Therefore, it does not meet the existing needs. We propose a combined multi-nozzle water tank. Summary of the invention

[0015] The present invention has the following beneficial effects: 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; 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.

[0016] 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 of the inside of the butt pipe, 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.

[0017] 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 DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1: This embodiment is intended to promote the solution of the problem that during the use of the water flosser, clean water is stored in the shell, and the water in the water tank is pumped out and pressurized by a water pump to form a high-pressure water flow for cleaning teeth and gum gaps. In addition, during the use of the water flosser, the operator also uses a cleaning liquid to rinse the teeth, but most water flossers are usually equipped with only one water tank. Therefore, when using different liquids, the water tank needs to be taken out and replaced with other liquids, making the teeth washing process cumbersome. Please refer to Figure 1 - Fig. 9 A combined multi-nozzle water flosser includes a water flosser housing 110 and an electronic component 111 installed inside the water flosser housing 110. A liquid storage box 120 is rotatably installed inside the water flosser housing 110. The liquid storage box 120 includes a first liquid storage chamber 121 and a second liquid storage chamber 122. The first liquid storage chamber 121 is used to place liquid. It should be noted that the liquid placed in the first liquid storage chamber 121 is clean water, and the second liquid storage chamber 122 is used to place cleaning liquid. It should be noted that the liquid placed in the second liquid storage chamber 122 can be antibacterial mouthwash or other oral care liquid.

[0030] A nozzle 123 and a docking tube 124 are installed on the water flosser housing 110, and liquid supply tubes 125 are installed inside the first liquid storage chamber 121 and the second liquid storage chamber 122 respectively. The nozzle 123, the docking tube 124 and the liquid supply tube 125 are communicated with each other, and two flow limiting plates 130 are rotatably installed inside the docking tube 124. The two flow limiting plates 130 are used to adjust the flow rate of the liquid, and a control box 140 for adjusting the rotation range of the flow limiting plates 130 is installed on the side of the docking tube 124, and a control rod 112 for driving the control box 140 to operate is installed on the liquid storage box 120.

[0031] It should be noted that the electronic component 111 includes 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 water through the cooperation of the control unit and the water pump. Its specific model, working principle and usage are well known to technical personnel in this field and will not be elaborated here.

[0032] A placement groove 150 is provided inside the water flosser housing 110, and the liquid storage box 120 can be detachably placed inside the placement groove 150. A first sealing ring 151 is installed on the upper side of the liquid storage box 120, and the first sealing ring 151 is connected to the liquid supply tube 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 ball 152 is made of steel, and a liquid inlet 153 is provided on the surface of the liquid supply ball 152. The liquid supply ball 152 is communicated with the liquid supply tube 125, and the liquid supply tube 125 is set as a hose. A second sealing ring 154 is installed on the bottom side of the docking tube 124, and the second sealing ring 154 fits with the first sealing ring 151 to improve the sealing performance between the liquid supply ball 152 and the liquid supply tube 125.

[0033] See Figure 1 , Figure 2 and Figure 3 In a specific implementation, a locking groove 160 is provided on the bottom side of the liquid storage box 120, and a locking column 161 is rotatably installed on the bottom side of the water flosser housing 110, and the end of the locking column 161 is locked in the locking groove 160. A driving groove 162 is provided on the inner wall of the water flosser housing 110, and a gear column 163 is installed on the locking column 161, and the gear column 163 is located in the driving groove 162. When the operator switches the cleaning liquid or clean water, the locking column 161 is rotated. Since the locking column 161 is engaged with the locking 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 chamber 121 and the second liquid storage chamber 122 are swapped, and at the same time, the docking tube 124 and the liquid supply tube 125 are re-connected, thereby switching different liquids; not only that, through the cooperation of the liquid supply tube 125, the docking tube 124 and the electronic component 111, water can be discharged from the water flosser housing 110.

[0034] See Figure 1 , Figure 2 , Figure 3 and Figure 4 A 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 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 163 It is stationary so that the end of the elastic strip 165 is no longer squeezed. At this time, 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 down the engaging column 161. At this time, the engaging column 161 loses engagement with the engaging groove 160, and at the same time causes the loss of engagement with the liquid storage box 120, thereby facilitating the operator to take out the liquid storage box 120 from the inside of the oral irrigator housing 110.

[0035] It should be noted that the liquid storage box 120 is provided with a water inlet for replenishing liquid.

[0036] 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 disassemble and install the liquid storage box 120, and the position of the liquid storage chamber can be switched by simply rotating the engaging column 161, thereby realizing the use of different liquids. 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.

[0037] 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 flow rate of liquid is used, excessive waste of cleaning liquid may occur. Moreover, many cleaning liquids need to have a certain contact time with the teeth. When the flow rate of cleaning liquid 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 Figure 1 - Fig. 9 A 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.

[0038] 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.

[0039] 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. 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 the 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 flow limiting plates 130 that were originally close to each other move away from each other and open, so that the liquid inside the connecting pipe 124 is blocked and the water output is reduced. 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.

[0040] 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, in the process of rotating the liquid storage box 120, the control rod 112 contacts the support rod 142, so that the support rod 142 drives the sliding block 141 to move upward, and in the process of moving upward, the first rotating rod 170 and the second rotating rod 171 are rotated by the cooperation of the connecting groove 182 and the sliding column 173, so that the two originally close flow limiting plates 130 are moved away from each other, thereby achieving the blockage inside the butt pipe 124, so that the two flow limiting plates 130 block the liquid, so that the water output of the cleaning liquid is reduced; through the rotation of the two flow limiting plates 130, excessive cleaning liquid is prevented from entering the oral cavity, and the reduction of the 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 cavity surface, delaying the time for the cleaning liquid to overflow the oral cavity, and also reducing the waste of the cleaning liquid, thereby improving the use efficiency.

[0041] Embodiment 3: This embodiment is intended to solve the problem that the liquid remaining in the pump body may flow back and affect the water quality during the switching process of different liquids. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1 - Fig. 9A connecting pipe 190 is installed on the side of the butt-joint pipe 124, the connecting pipe 190 is communicated with the butt-joint 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, a connecting rod 194 is installed on the end of the piston block 191, and a pushing ball 195 is installed on the end of the connecting rod 194, 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, and the first one-way valve 211 is used to intake air into the connecting pipe 190, and a second one-way valve 212 is installed at the connection between the connecting pipe 190 and the butt-joint pipe 124, and the second one-way valve 212 is used to blow air into the butt-joint pipe 124 and prevent liquid from flowing into the connecting pipe 190; During specific implementation, as the liquid storage box 120 rotates, the push rod 210 rotates along with the liquid storage box 120. During the rotation, the push rod 210 is used to resist the push ball 195, so that the push ball 195 drives the connecting rod 194 to move toward the inside of the connecting tube 190. During the movement, the piston plate is driven, 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, thereby blowing air into the docking tube 124 and blowing out the residual liquid inside the pump body through the nozzle 123.

[0042] 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 inside the docking pipe 124. The third one-way valve 240 is used to prevent liquid reflux.

[0043] 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.

[0044] 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.

[0045] 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.
