DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0018] Example: See Figure 1 As shown:

[0019] A portable teeth washer comprises a nozzle 1, an adapter 2 and a water bottle 7.

[0020] See also Figure 1 As shown, the nozzle 1 is detachably connected to the front end of the adapter 2, and the specific detachable connection method is preferably: a circle of card slots 11 are provided on the rear end of the nozzle 1, and a retaining spring is provided in the socket corresponding to the rear end of the nozzle 1 on the adapter 2 corresponding to the card slot 11, and the rear end of the nozzle 1 is inserted into the socket of the adapter 2 corresponding to the rear end of the nozzle 1, and the retaining spring and the card slot 11 are engaged and matched, thereby forming a very convenient plug-in and pull-out structure, and the nozzle can be used as soon as it is inserted. In addition, for sealing, a sealing ring is provided on the rear side of the retaining spring in the socket corresponding to the rear end of the nozzle 1 of the adapter 2, and the sealing ring is pressed against the outer periphery of the rear end of the nozzle 1 to form a sealed connection.

[0021] See also Figure 1 As shown, the rear end of the adapter 2 is an interface 21 for docking with an external water bottle. The interface 21 is preferably a universal internal thread interface so that it can be docked with most of the mineral water bottles on the market.

[0022] See also Figure 1 As shown, the core of this embodiment is: a columnar body 22 is extended rearward from the middle of the interface 21 of the adapter 2, and the columnar body 22 is for being extended and placed in an external water bottle. In terms of design, the outer diameter of the columnar body 22 needs to be smaller than the diameter of the bottle mouth of the mineral water bottle, and the specific diameter is equal to or less than 24.5 mm.

[0023] See also Figure 1 As shown, a sealed cavity 221 is provided in the columnar body 22 along its axial direction, and the sealed cavity 221 is sealed to the outside. A battery 3, a motor 4, a transmission mechanism 5 and a piston cylinder 6 are arranged in sequence from back to front in the sealed cavity 221 along the axial direction of the columnar body 22.

[0024] See also Figure 1 As shown, the piston cylinder 6 includes a cylinder body 61 and a piston 62. The front end of the cylinder body 61 extends into the adapter 2, and a water outlet 611 is provided thereon to communicate with the nozzle 1. The front end of the cylinder body 61 is also provided with a water suction port 612 to connect to the inner cavity of an external water bottle through a water suction pipe 8. The first one-way valve 6111 is provided at the water outlet 611, and the conducting direction of the first one-way valve 6111 is from the cylinder body 61 to the nozzle 1. The second one-way valve 6121 is provided at the water suction port 612, and the conducting direction of the second one-way valve 6121 is from the water suction pipe 8 to the cylinder body 61.

[0025] See also Figure 1 As shown, the rear end of the piston 62 is connected to the motor 4 via the transmission mechanism 5, and the battery 3 supplies power to the motor 4.

[0026] See also Figure 1As shown, the preferred solution of the transmission mechanism 5 is: the transmission mechanism 5 includes a connecting rod 51, an eccentric shaft 52 and a gear 53. The eccentric shaft 52 includes an eccentric shaft body 521 and a circumferential tooth portion 522 arranged on the outer periphery of the eccentric shaft body 521. The eccentric shaft 52 is rotatably arranged relative to the shell column 22. The rotation center of the eccentric shaft 52 is perpendicular to the axis direction of the drive shaft of the motor 4. The axis of the outer edge of the eccentric shaft body 521 deviates from its rotation center. Specifically, the front end of the connecting rod 51 is hinged on the piston 62, and the rear end thereof is provided with a sleeve circular hole 512, which is sleeved on the eccentric shaft body 521 of the eccentric shaft 52, and the gear 53 is connected to the drive shaft of the motor 4, and the gear 53 is meshed with the circumferential tooth portion 522 of the eccentric shaft 52. Thus, when the motor 23 rotates, the piston 62 is driven to reciprocate in the cylinder 61 in the forward and backward directions through the gear 53, the eccentric shaft 52, and the connecting rod 51, so as to achieve water absorption and water spraying. The above transmission mechanism 5 is a specific example, and can be replaced by other transmission mechanisms in practice, as long as it can convert the rotational motion of the motor into a linear short-stroke reciprocating motion.

[0027] See also Figure 1 As shown, the water suction pipe 8 can also be arranged in the columnar body 22 and located beside the sealed cavity 221. Specifically, the water suction pipe 8 can be a channel opened in the columnar body 22, or a separate independent pipe body embedded therein. The upper end of the water suction pipe 8 is connected to the water suction port 612 through a pipeline, and the lower end of the water suction pipe is connected to the bottom of the columnar body 22 to communicate with the bottom of the inner cavity of the water bottle 7 for water suction.

[0028] See also Figure 1 As shown, the battery 3 is preferably a storage battery, and the adapter 2 is provided with a magnetic waterproof charging interface 23, which is electrically connected to the storage battery, so that it is both waterproof and convenient to charge.

[0029] See also Figure 1 As shown, the tooth washer of this embodiment can be equipped with a protective cover, which is cylindrical, with one end closed and the other end provided with a connection port. The protective cover is connected to the interface 21 via the connection port to cover the columnar body 22 for protection, so as to protect the portion below the tooth washer adapter interface 21 from dust when not in use. When in use, the protective cover can be directly removed and replaced with a readily available mineral water bottle, beverage bottle, etc., and the product can be used directly.

[0030] See also Figure 1 As shown, the tooth washer of this embodiment can also be equipped with a water bottle 7 according to user needs. The water bottle 7 is provided with a connecting port, and the connecting port is connected to the port 21. The columnar body 22 extends into the water bottle 7. When in use, the user can directly fill the water in the water bottle 7 and use it directly.

[0031] The battery in this embodiment can last for 10 days, is magnetically charged, and is waterproof and portable.

[0032] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
