[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0023] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0024] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature.

[0025] Referring to the drawings of the specification, a tooth cleaner with pulsed water includes a chamber 10 that can be connected to a water source. The water source can be water flowing directly from a faucet. The tooth cleaner also includes a housing and other components. It is similar to the prior art and will not be elaborated on in detail. A rotating shaft 11 and a pulling rod 20 are provided in the chamber. An eccentric wheel 12 is provided on the rotating shaft. The rotating shaft and the eccentric wheel are eccentrically arranged. A movable groove 21 is provided on the pulling rod. The eccentric wheel can abut and cooperate with the peripheral side wall of the movable groove to make the pulling rod The movable rod can intermittently move up and down within the chamber. In other words, the rotation of the rotating shaft can drive the pull rod to perform piston-like movement, achieving up and down movement. The chamber also includes a water outlet 13. The pull rod is equipped with a sealing plug 22 that can cooperate with the water outlet. The sealing plug can achieve intermittent opening and closing of the water outlet. When the pull rod is at the uppermost position, the sealing plug blocks the water outlet, and the nozzle does not discharge water. When the pull rod moves downward, the sealing plug separates from the water outlet, and the nozzle can discharge water. To facilitate the rapid reset of the pull rod, a return spring 23 is also provided between the pull rod and the chamber.

[0026] Preferably, it further comprises an upper body 31 and a lower body 32 that are connected in a matching manner. The interior between the upper body and the lower body forms the chamber. In fact, the upper body and the lower body are put together, and then the chamber is formed inside; the chamber is a sealed space. The water outlet is arranged above the upper body. A nozzle 40 is also connected to the upper body. The water inlet end of the nozzle can be connected to the water outlet. A fixing seat 41 is also provided above the upper body. The nozzle can be fixedly connected to the upper body via the fixing seat. The fixing seat can be fixedly connected to the upper body. Then the bottom of the nozzle (water inlet end) is sleeved in the fixing seat. At the same time, a sealing ring 42 is provided between the upper body, the fixing seat and the nozzle.

[0027] Furthermore, the lower body includes a water inlet 33 and a water outlet 34, and the direction of water flow in the water outlet is not parallel to the lifting direction of the pull rod. The lower body is provided with a baffle 35 at the end of the water inlet, and the water flow of the water inlet flows out of the water outlet through the baffle. The water outlet is arranged horizontally in the lower body so that the water flow out of the water outlet does not directly impact the pull rod. In other words, the water in the water inlet is taken in from the bottom to the top, and when it reaches the baffle, the water is discharged horizontally from the water outlet on the side of the lower body. Multiple water outlets can be provided, distributed in a ring around the outer periphery of the water inlet. A water inlet pipe 43 is provided on the outer periphery of the water inlet, and the other end of the water inlet pipe is directly connected to the faucet.

[0028] Furthermore, the rotating shaft is disposed transversely within the chamber, with one end of the rotating shaft extending out of the chamber to communicate with the motor 50. A seal 14 is sleeved around the outer periphery of the rotating shaft to engage with the sidewall of the chamber. The motor is connected to the rotating shaft via a reduction gear 51, which may include a bevel gear connected to the motor, a gear plate connected to the rotating shaft, and a battery 52 that can be connected to the motor.

[0029] In a preferred embodiment, the diameter of the water outlet is no greater than 10 mm.

[0030] More specifically, the present invention utilizes a motor that, through a reduction gear, drives an eccentric wheel to rotate within a movable groove of a pull rod, thereby driving the pull rod to slide back and forth up and down within a chamber. A sealing plug is connected to one end of the pull rod, which drives the sealing plug and the water outlet to form a water-stopping and water-releasing function. The upper end of the upper body includes a water outlet with a size of less than 10 mm. A return spring within the chamber is used to quickly reset the pull rod. After the motor is decelerated and the torque is increased by the reduction device, the eccentric wheel is driven to perform a circular motion through the rotating shaft. The eccentric wheel is in the middle movable groove of the pull rod, thereby driving the pull rod to slide back and forth up and down. The pull rod is provided with a sealing plug at one end and a reset spring at the other end. The sealing plug and the water outlet form a cut-off and conduction effect. After water enters from the lower body, the water flows out from the side due to the action of the baffle, reducing the impact of the water flow on the pull rod, making the pull rod easy to slide, and the water flows out from the water outlet after flowing out of the water hole. The continuous tap water flow stops or flows out at the sealing plug and the water outlet, forming a pulse effect, and then flows out from the nozzle; and the smaller the sealing diameter at the water outlet, the better, generally less than 10mm, to reduce the water pressure during sealing, making the pull rod easier to slide.

[0031] The foregoing description shows and describes preferred embodiments of the present invention. As previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge of the relevant art. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
