Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a dental flosser. Background Technology

[0002] A water flosser typically consists of a main body, a cleaning solution tank, and a nozzle. The main body is retractably mounted on the cleaning solution tank. When in use, the main body moves outside the cleaning solution tank, which holds the cleaning solution. When it needs to be stored, the cleaning solution in the tank is emptied, and then most of the main body is moved back into the tank for storage.

[0003] Water pump components are typically installed inside the main body. In existing technologies, water pump components are usually directly installed inside the main body. Although this installation is convenient, errors may occur during the assembly process, or the water pump components may generate significant vibrations during operation after prolonged use, affecting the user experience.

[0030] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] refer to Figure 1-9 , Figure 1 and 2 A water flosser 100 is disclosed, comprising an outer shell 1 defining a receiving cavity, a cleaning fluid tank 2 for containing cleaning fluid, and a nozzle 3. The water flosser 100 generally includes a usage state (see reference). Figure 1 ) and storage status (refer to) Figure 2 When the oral irrigator 100 is in use, most of the outer casing 1 is located outside the cleaning solution tank 2, which is used to hold the cleaning solution. When the oral irrigator 100 is in the stored state, the outer casing 1 is stored inside the cleaning solution tank 2. The oral irrigator 100 includes a water pump assembly 4 and a mounting bracket 41 for mounting the water pump assembly 4. The water pump assembly 4 is used to pump the cleaning solution in the cleaning solution tank 2 to the area around the teeth through the nozzle 3. The water pump assembly 4 includes a support frame 14 and a driver 15, a transmission mechanism 16, and a fluid distribution mechanism 17 disposed on the support frame 14. The driver 15 drives the transmission mechanism to pump the fluid in the cleaning solution tank 2 to the nozzle 3. The working principle of the oral irrigator 100 is well known to those skilled in the art and will not be described in detail here. This application mainly discloses a structure that distinguishes it from other oral irrigators 100.

[0032] refer to Figure 3-9 This section details the mounting bracket 41 and its installation method. The mounting bracket 41 is installed within the receiving cavity. The mounting bracket 41 includes a first bracket 42 and a second bracket 43, which cooperate to fix the water pump assembly 4 to the mounting bracket 41. (Reference) Figure 6-9The first bracket 42 is positioned above the second bracket 43, and the two are fixedly connected. A first installation space 27 is defined between the first bracket 42 and the second bracket 43 for installing the water pump assembly 4, which can be fixed into the bracket. After the water pump assembly 4 is fixed to the mounting bracket 41, the mounting bracket 41 is then assembled into the outer casing 1. This pre-installation method allows the water pump assembly 4 to be fixed first, and then the mounting bracket 41 to be fixed into the outer casing 1, which can effectively ensure the consistency of the water pump assembly 4 during installation and avoid large vibrations during operation. The various mounting structures can be connected by threads, snap-fit ​​connections, or a combination of both. Other forms of connection are also possible, such as ultrasonic welding. The first bracket 42 is provided with a through hole, through which the nozzle 3 can communicate fluidly with the fluid distribution mechanism 17 of the water pump assembly 4.

[0033] refer to Figure 3 and 5 The accommodating cavity includes a first cavity 11 and a second cavity 12. In order to improve the waterproof performance, a sealing structure 13 is provided on the first bracket 42. The sealing structure 13 is used to achieve a seal between the first cavity 11 and the second cavity 12.

[0034] refer to Figure 3-9 The outer casing 1 includes a first casing 31 and a second casing 32, which cooperate to fix the mounting bracket 41 to the receiving cavity. A mounting plate (not shown in the figure) may also be provided between the first casing 31 and the second casing 32. The mounting plate 33 can be used to fix the mounting bracket 41 to the second casing 32, and then the first casing 31 is fixed to the second casing 32. The connection method can be any of the connection methods mentioned above, which will not be detailed here.

[0035] To facilitate the addition of cleaning solution to the cleaning solution tank 2, the outer casing 1 also includes a fluid channel 18 that connects to the cleaning solution tank 2. The cleaning solution can enter the cleaning solution tank 2 through the fluid channel 18. Alternatively, the bottom of the cleaning solution tank 2 can also have a separate opening for injecting or pouring cleaning solution out of the container.

[0036] The structure of nozzle 3 is a common structure in the prior art, used by major manufacturers, and will not be described in detail here. Nozzle 3 is detachably mounted to housing 1. A locking mechanism 20 is provided between housing 1 and the first bracket 42. The locking mechanism 20 is configured to allow nozzle 3 to be in an unlocked or locked state relative to housing 1. (Reference) Figure 8 and 9The locking mechanism 20 includes a mounting member 22 and a locking member 21. The mounting member 22 is mounted on the first bracket 42, and the locking member 21 is mounted on the mounting member 22. The locking member 21 can move relative to the mounting member 22 to achieve locking / unlocking. Specifically, the mounting member 22 is mounted at the through hole of the first bracket 42, and the locking member 21 is movably mounted on the mounting member 22. A spring 23 is provided on the locking mechanism 20, and the locking member 21 is locked by the elastic force of the spring 23. When the locking member 21 is subjected to force, the locking member 21 overcomes the elastic force and moves to the unlocked position, and the nozzle 3 can be removed from the outer casing 1.

[0037] The water flosser 100 also includes a battery pack 19 for powering the water pump assembly 4, the battery pack 19 being mounted on a mounting bracket 41. The mounting bracket 41 secures the water pump assembly 4 and also secures the battery pack 19 to the mounting bracket 41. Specifically, a second bracket 43 defines a second mounting space 28 within which the battery pack 19 can be securely mounted.

[0038] The water flosser 100 also includes a charging structure 25 for charging the battery pack 19, which is mounted on the first bracket 42. The charging structure 25 may include a plurality of charging pins and may also include a magnetic structure that can cooperate with a magnetic structure on the charging cable to achieve a magnetic connection.

[0039] A germicidal lamp 26 is also installed inside the receiving cavity, located directly above the cleaning solution tank 2. (Reference) Figure 7 In the embodiment shown in the figure, the germicidal lamp 26 is installed at the bottom of the mounting bracket 41. The light generated by the sterilization device can pass through the light-transmitting material on the outer casing 1 and directly illuminate the interior of the cleaning liquid tank 2. The germicidal lamp 26 can be an ultraviolet lamp. Of course, the germicidal lamp 26 can also be other forms of devices that can achieve the sterilization function.
