[0002] With increasing awareness of oral health, the market demand for water flossers, as a highly efficient and portable oral care device, continues to rise. In the production and assembly process of water flossers, the connection and fixation of the top cover, bottom cover, nozzle retainer, and body shell is a crucial step, directly affecting the product's sealing performance, structural stability, and user experience. Currently, the industry commonly uses welding technology to assemble these components to the body shell. High-temperature melting of the contact surface material creates a strong bond between the components, ensuring that the water flosser will not experience loosening or leakage during daily use.

[0003] However, the welding process in existing oral irrigator production is highly dependent on manual operation. Specifically, operators need to hold welding tools and rely on experience to align the parts for welding. This not only requires a high level of skill from the operators but also results in low overall assembly efficiency, which cannot meet the needs of large-scale mass production and seriously restricts the capacity expansion and market competitiveness of oral irrigator manufacturers.

[0026] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0027] See Figure 1-3As shown, this embodiment discloses a dental floss welding device, which includes: a welding device 1 and a clamping device 2; the clamping device 2 is used to clamp a substrate, and the welding device 1 is used to weld the workpiece to be welded onto the substrate; the welding device 1 includes: a base 11 and a welding head 12; the welding head 12 is movably connected above the base 11; the clamping device 2 is disposed between the base 11 and the welding head 12.

[0028] It is understood that in this embodiment, the base is the outer shell of the water flosser, and the workpiece to be welded is the upper cover, bottom cover, or nozzle retainer that needs to be welded to the outer shell. In other embodiments, other workpieces or components can be used to replace the outer shell, upper cover, bottom cover, and nozzle retainer, depending on actual needs. In specific implementation, the workpiece to be welded is placed at the welding point of the base beforehand, and the base is clamped by the clamping device 2. Then, the welding device 1 is started, so that the welding head 12 approaches the welding point and welds the workpiece to be welded to the outer shell.

[0029] The water flosser welding equipment of this embodiment uses the clamping device 2 to stably clamp the base body and the welding head 12 to accurately complete the welding of the workpiece to be welded to the base body, replacing the traditional manual welding operation, improving the welding efficiency of water flosser production and assembly, while ensuring the accuracy of the welding position and the consistency of the welding strength, reducing the cost of quality inspection and rework, and helping enterprises meet the needs of large-scale mass production.

[0030] In this embodiment, the welding device 1 is an ultrasonic welding machine. During operation, the clamping device 2 continuously applies a stable clamping force to the substrate to prevent it from shaking during welding. The welding head 12 moves precisely to the welding position according to a preset program on the ultrasonic welding machine, completing the welding with fixed pressure and welding parameters. The entire process requires no manual intervention, forming an automated welding cycle. More specifically, after the ultrasonic welding machine starts, the welding head 12 contacts the workpiece under high-frequency vibration. The vibration energy is converted into frictional heat, melting the contact surface between the workpiece and the substrate. Under the pressure of the welding head 12, the two fuse to form a weld joint. Then, the vibration stops, and the welding head 12 maintains pressure until the weld joint cools and solidifies. Using ultrasonic welding technology, no additional solder is needed during the welding process. The heating is concentrated and the heat-affected zone is small, avoiding problems such as deformation and aging of the plastic parts of the dental flosser due to high temperatures. Simultaneously, the welding speed is fast and the joint strength is high, further improving welding efficiency and product reliability.

[0031] In a further embodiment, the welding device 1 further includes a drive mechanism 13; the drive mechanism 13 is connected to the base 11, and the welding head 12 is connected to the drive mechanism 13; the drive mechanism 13 is used to drive the welding head 12 to perform lifting and lowering actions. Preferably, the drive mechanism 13 includes a lead screw and a motor connected to the lead screw. After receiving a control signal, the drive mechanism 13 drives the lead screw through the motor to move the welding head 12 in the vertical direction. During welding, the welding head 12 is driven to descend to contact the workpiece to be welded and apply a preset pressure. After welding is completed, the welding head 12 is driven to rise to the initial position, waiting for the next welding command. The drive mechanism 13 realizes the automation and precise control of the lifting and lowering action of the welding head 12, ensuring that the descent distance and pressure of the welding head 12 are consistent each time welding, reducing human operation errors and improving the stability of welding parameters.

[0032] In a further embodiment, the clamping device 2 includes a mounting plate 21, which is disposed on the upper surface of the base 11. The mounting plate 21 is fixed to or placed on the upper surface of the base 11 by bolts or other connecting parts, providing a mounting platform for other components of the clamping device 2. During the welding process, the mounting plate 21 transmits the clamping force and welding reaction force of the clamping device 2 to the base 11, maintaining the stability of the overall structure.

[0033] In a further embodiment, the clamping device 2 further includes: a fixed clamping block 22 and a movable clamping block 23; the fixed clamping block 22 is fixedly connected to the mounting plate 21, and the movable clamping block 23 is slidably connected to the mounting plate 21; the movable clamping block 23 and the fixed clamping block 22 are symmetrically arranged, and clamping grooves are provided on the sides of the fixed clamping block 22 and the movable clamping block 23 that are close to each other. The movable clamping block 23 slides along the mounting plate 21 toward the fixed clamping block 22. When the substrate is placed between the two, the symmetrically arranged clamping grooves conform to the shape of the substrate and form a wrapping clamp on the substrate from both sides, so that the substrate cannot move or rotate in the horizontal direction during the welding process.

[0034] In a further embodiment, the clamping device 2 further includes an opening / closing drive 24; the opening / closing drive 24 is used to drive the movable clamping block 23 closer to or further away from the fixed clamping block 22. After receiving a control command, the opening / closing drive 24 outputs a driving force to push the movable clamping block 23 to slide along the mounting plate 21. When it is necessary to clamp the substrate, the movable clamping block 23 is driven closer to the fixed clamping block 22 until the substrate is clamped; after welding is completed, the movable clamping block 23 is driven away from the fixed clamping block 22 to release the substrate for removal. The opening / closing drive 24 realizes the automated opening and closing of the movable clamping block 23, replacing manual operation of the clamping block, reducing manual intervention time, improving the response speed of the clamping action, and ensuring consistent clamping force each time, avoiding substrate positioning deviation caused by uneven manual clamping force.

[0035] In a further embodiment, the clamping device 2 further includes: a mounting base 25; the mounting base 25 is fixedly connected to the mounting plate 21 and is located on the side of the movable clamping block 23 away from the fixed clamping block 22, and the opening and closing drive member 24 is mounted on the mounting base 25. The mounting base 25 is fixed to the mounting plate 21 by welding or bolts, providing rigid support for the opening and closing drive member 24. When the opening and closing drive member 24 outputs driving force, the mounting base 25 bears the reaction force and transmits it to the mounting plate 21, ensuring that the position of the drive member does not shift during operation.

[0036] In a preferred embodiment, the opening / closing drive component 24 is a telescopic cylinder. The telescopic cylinder is mounted on the side of the mounting base 25 away from the movable clamping block 23, and the mounting base 25 has a through hole (not shown in the figure). The piston rod of the telescopic cylinder passes through the through hole and is fixedly connected to the movable clamping block 23. When the telescopic cylinder is vented, the piston rod extends to push the movable clamping block 23 towards the fixed clamping block 22, thereby clamping it. When the telescopic cylinder is vented, the piston rod retracts to drive the movable clamping block 23 to move in the opposite direction, thereby releasing it. Using a telescopic cylinder as the drive component provides fast response speed, stable output force, and the through hole structure ensures accurate piston rod movement trajectory, preventing the movable clamping block 23 from deviating.

[0037] In a further embodiment, the mounting plate 21 is provided with a guide rail 211, and the movable clamping block 23 is slidably connected to the guide rail 211. The bottom of the movable clamping block 23 cooperates with the guide rail 211 and slides along the length direction of the guide rail 211 under the drive of the opening and closing drive member 24. The guide rail 211 restricts the movement direction of the movable clamping block 23, so that it can only move along a straight trajectory close to or away from the fixed clamping block 22, avoiding jamming or deviation during the sliding process. The guide rail 211 provides precise guidance for the movable clamping block 23, reduces sliding friction resistance, and makes the opening and closing action of the clamping block more stable and smooth; at the same time, it ensures that the relative position of the movable clamping block 23 and the fixed clamping block 22 is always accurate, improves the consistency of clamping and positioning, and further ensures welding accuracy.

[0038] In a further embodiment, the flosser welding equipment also includes two sensors 3. The two sensors 3 are symmetrically arranged and form a light curtain barrier located outside the clamping device 2. These sensors sense the on / off signal of the light curtain barrier to control the start and stop of the welding device 1. When an operator's hand or other object enters the light curtain area outside the clamping device 2, the light is blocked, and the sensor 3 immediately sends a signal to the control system of the flosser welding equipment. The control system then stops the operation of the welding device 1. When the object leaves and the light curtain is restored to its original state, the welding device 1 can be restarted. The light curtain barrier forms a real-time safety monitoring area, which can promptly trigger a shutdown when personnel or objects approach the welding station, preventing accidental operation of the welding head 12 that could cause personal injury or equipment damage. This provides reliable safety protection for equipment operation and reduces the risk of production accidents.

[0039] In a preferred embodiment, sensor 3 is a grating sensor, with one grating sensor acting as a transmitter and the other as a receiver. The light emitted by the transmitter is received by the receiver to form a light curtain barrier. The presence or absence of an object or human hand interrupting the light curtain barrier is determined by monitoring the signal received by the receiver. If so, the welding device 1 stops operating; otherwise, the work area is safe, and the welding device 1 can operate. The multi-beam design of the grating sensor improves sensing sensitivity and coverage, reduces blind spots in safety monitoring, and ensures accurate detection even when small objects or limbs are close. Automated safety control is achieved through signal on / off switching, with a fast response time, effectively protecting the personal safety of operators.

[0040] In a further embodiment, the welding equipment for the punch further includes a control valve 4; the control valve 4 is used to start and stop the opening and closing drive component 24. The control valve 4 is connected to the telescopic cylinder via a pipe (not shown), which is used to transmit compressed air. After the clamping device 2 clamps the substrate and is ready, the operator manually operates the control valve 4 to control the on / off state and flow direction of the compressed air. When clamping is required, the control valve 4 is operated to open the air intake pipe, and the compressed air enters the telescopic cylinder through the pipe to push the piston rod to extend; when releasing is required, the control valve 4 is operated to switch the pipe, and the telescopic cylinder exhausts air to retract the piston rod. The control valve 4 achieves precise control of the opening and closing drive component 24, controls the air path on / off via an electrical signal, has a fast response speed and high control accuracy, and ensures that the clamping action is precisely synchronized with the welding process.

[0041] In a further embodiment, the control valve 4 is located on the side of the light curtain barrier away from the clamping device 2. When operators adjust or operate the control valve 4 outside the light curtain barrier, their bodies or tools will not enter the light curtain area, avoiding accidental interruption of the light curtain and affecting the normal operation of the equipment. During equipment operation, the control valve 4 works independently in a safe area, unaffected by the movements of the clamping device 2 and the welding device 1. The position of the control valve 4 facilitates operation and maintenance by operators in a safe area, avoids triggering the safety light curtain due to proximity to the welding area, ensuring the continuity of equipment operation; at the same time, it reduces interference from external factors on the control valve 4, improving the stability of equipment operation.

[0042] This embodiment provides a welding device for water flossers. It uses a clamping device to stably hold the base and uses a welding head to accurately complete the welding of the workpiece to be welded to the base. This replaces the traditional manual welding operation, improves the welding efficiency of water flosser production and assembly, ensures the accuracy of the welding position and the consistency of the welding strength, reduces the cost of quality inspection and rework, and helps enterprises meet the needs of large-scale mass production.
