Description

Technical Field

[0001] This utility model belongs to the field of oral care and cleaning, and specifically relates to a tabletop water flosser that is easy to store. Background Technology

[0002] A water flosser is an auxiliary tool for cleaning the oral cavity. It uses pulsating water jets to clean teeth and between teeth. There are mainly handheld and countertop types. The biggest advantage of countertop water flossers is that their water tanks are much larger than portable ones, making them suitable for multiple family members to use together. Countertop water flossers are typically placed on the bathroom sink. However, placing a countertop water flosser on a sink, which is already limited in space, requires minimizing its space occupation. Compared to larger countertop water flossers on the market, they cannot be compressed when not in use, still occupying a significant amount of countertop space. Furthermore, the exposed nozzle is prone to dust and moisture accumulation, fostering bacterial growth and severely impacting the user experience. Therefore, there is an urgent need for a countertop water flosser solution that can achieve compact storage, corner fit, and moisture protection. Utility Model Content

[0003] (1) Technical problems to be solved This invention provides a conveniently stored countertop water flosser, aiming to solve the problem of large storage space.

[0004] (2) Technical solution This utility model provides a conveniently stored countertop water flosser, including a main unit and a water tank. The main unit includes a housing and a water flossing device disposed within the housing. The water tank is detachably connected to the housing. The water tank has a water storage tank and a positioning groove with opposite opening orientations and corresponding vertical positions. The inner walls of the water storage tank and the positioning groove are matched with the outer wall of the housing. The depth of the water storage tank is greater than the depth of the positioning groove. The bottom of the water storage tank is provided with a drain hole, and the top of the main unit is provided with a water inlet hole corresponding to the drain hole. The water inlet hole is connected to the flushing device. When in use, the water tank's water storage tank opening faces upwards, and the positioning groove is fitted and snapped onto the top of the housing, so that the drain hole and the inlet hole are aligned and connected. When stored, the positioning groove of the water tank faces upward, and the water storage tank is fitted and wraps around the perimeter of the shell to reduce the storage space of the water flosser.

[0005] Both the host and the water tank have right-angled triangle cross-sections, each including two right-angled surfaces and one inclined surface, with rounded transitions between the two right-angled surfaces and between the two right-angled surfaces and the inclined surface.

[0006] Furthermore, the housing includes a first boss and a first step extending outward from the bottom edge of the first boss. In the retracted state, the first abutting surface S1 of the first boss abuts against the second abutting surface S2 of the water storage tank.

[0007] Furthermore, the depth of the positioning groove is C, the water storage depth of the water storage tank is E, and the height of the first boss of the shell is F, and C <E<=F。

[0008] Furthermore, the ratio of the water storage depth E of the water storage tank to the tank depth C of the positioning tank is greater than or equal to 4, that is, E / C≥4.

[0009] Furthermore, the vertical cross-sectional groove shape of the water storage tank, the positioning groove, and the first boss are all trapezoidal. In the stored state, the groove shape of the first boss and the water storage tank are both regular trapezoidal, while the groove shape of the positioning groove is an inverted trapezoidal.

[0010] Furthermore, the outer walls of the water storage tank and the positioning tank are smoothly transitioned and both extend in the same straight line.

[0011] Furthermore, when the shell is connected to the water storage tank or the positioning groove, a storage space is provided between the outer peripheral wall of the shell and the inner peripheral wall of the water storage tank or the positioning groove, and the width of the storage space is G, where G = 1 mm.

[0012] Furthermore, the water tank is also provided with a tank cover, which is sleeved and connected to the opening of the water storage tank or the positioning groove.

[0013] Furthermore, the housing has a receiving cavity, and the inclined surface of the housing has a receiving groove. The oral irrigator includes a pump assembly disposed in the receiving cavity and an oral irrigator body installed in the receiving groove.

[0014] Furthermore, the pump assembly is connected to a water outlet pipe, the storage groove is provided with a cable placement groove, the cable placement groove wall is provided with a water outlet, the main body of the water flosser is connected to a flexible hose with a retractable telescopic section, the flexible hose passes through the water outlet and is connected to the water outlet pipe, in the storage state, the telescopic section is stored in the cable placement groove, in the use state, the telescopic section is at least partially stretched out of the cable placement groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The right-angled triangle shape of the main unit and water tank allows them to be placed close to a corner, reducing floor space. When the water tank is inverted for storage, it is highly compressed, further reducing its storage volume. The inverted water tank forms a fully enclosed enclosure, preventing moisture and dust from corroding the main unit's circuitry and the water flosser itself. The corner-oriented drainage design, combined with the drainage channel, prevents liquid stagnation and bacterial growth. The power interface is located in a right-angle bend recess, compatible with any corner socket location, and the recessed space naturally hides the power cord, eliminating clutter on the countertop. The angled integrated control area (water flosser body / indicator light) shortens the access path. Attached Figure Description

Detailed Implementation

[0055] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0056] See Figure 1-38 .

[0057] like Figure 1-2 As shown, this utility model provides a countertop water flosser, including a separable water tank 100 and a main unit 200. The water tank 100 is made of transparent material to facilitate observation of the water level. The water tank 100 has a water storage tank 101 and a positioning groove 102 with opposite openings and corresponding vertical positions. The bottom of the water storage tank 101 has a drain hole 103 communicating with the positioning groove 102. The top of the main unit 200 has a water inlet hole 11 corresponding to and communicating with the drain hole 103, to transport water from the water tank 100 to the main unit 200. The depth of the positioning groove 102 is significantly less than the depth of the water storage tank 101. The inner wall contours of both the water storage tank 101 and the positioning groove 102 are designed to fit snugly against the outer wall of the upper part of the main unit 200.

[0058] In use, the water tank 100 is positioned on the host 200 with the opening of the water storage tank 101 facing upwards and the opening of the positioning groove 102 facing downwards. The positioning groove 102 is fitted and engaged with the host 200, forming a structure in which the host 200 supports the water tank 100. In addition, when the positioning groove 102 is fitted onto the outer peripheral wall of the host 200, it can also limit and fix the water tank 100, preventing the water tank 100 from shifting and avoiding the risk of the water tank 100 falling, thereby enhancing the stability of the connection between the water tank 100 and the host 200.

[0059] When stored (not used for a long period, or when moving, or when packaged and shipped by the merchant), such as Figure 3 As shown, the water tank 100 is inverted so that the opening of the positioning groove 102 faces upward and the opening of the water storage tank 101 faces downward. Then, the water storage tank 101 is placed downwards on top of the main unit 200. Thanks to the depth design of the water storage tank 101, it can completely cover the main unit 200 after inversion, forming a storage state that encloses the main unit 200. This not only provides moisture and dust protection for the main unit 200, preventing damage from a humid environment and bacterial growth, but also significantly reduces the overall weight of the water flosser when stored. The height significantly saves storage space. The water tank 100 is also equipped with a cover 104, which is sleeved and connected to the opening of the water storage tank 101 or the positioning groove 102. In use, the cover 104 covers the water storage tank 101 to prevent impurities and dust from falling into the water storage tank 101 and ensuring water quality. In storage, the cover 104 covers the positioning groove 102 to prevent impurities and dust from falling into the positioning groove 102 and contaminating the drain hole 103.

[0060] Specifically, such as Figure 4 As shown, the main unit 200 includes a housing 1, a water flosser body 2, a pump assembly 3, and a bottom cover 4. The bottom cover 4 is detachably connected to the housing 1, and the connection method can be screwed, snap-fit, or glued. In this embodiment, the connection method is preferably screwed, which facilitates easy disassembly and assembly and ensures the stability of the connection between the bottom cover 4 and the housing 1. The housing 1 and the bottom cover 4 form a receiving cavity 14. The pump assembly 3 is disposed in the receiving cavity 14 and is used to pressurize the water flowing into the main unit 200, so that the pressurized water is sprayed out in a pulse to rinse the teeth. The pump assembly 3 has an inlet pipe 31 and an outlet pipe 32 that are interconnected. The inlet pipe 31 is connected to the inlet hole 11, and the outlet pipe 32 is connected to the water flosser body 2.

[0061] Furthermore, the receiving cavity 14 is provided with a storage component 5. The side wall of the storage component 5 is provided with a storage groove 51 that is adapted to the water flosser body 2. The water flosser body 2 is placed horizontally in the storage groove 51. The inclined surface 122 of the housing 1 is provided with a storage opening 1222 that corresponds to and communicates with the storage groove 51, making it convenient for the user to take out the water flosser body 2 from the storage groove 51 at any time through the storage opening 1222, making it more convenient to use. During installation, the housing 1 is flipped so that the opening of the receiving cavity 14 faces upward. The storage component 5 enters from the top downward from the opening of the receiving cavity 14, so that the end faces of the storage groove 51 and the storage opening 1222 are tightly abutted against each other to seal the storage opening 1222, ensuring the airtightness of the inside of the main unit 200.

[0062] It should be noted that when the main body 2 of the oral irrigator is stored in the storage slot 51, and the water tank 100 is inverted and fitted onto the main unit 200, the water storage tank 101 can simultaneously cover the housing 1 and the main body 2 of the oral irrigator, so as to simultaneously store and protect the main unit 200 and the main body 2 of the oral irrigator. This avoids the traditional situation where the main body 2 of the oral irrigator is exposed to the air, which makes it easy for dust to fall and bacteria to grow, as well as the damage to the main body 2 of the oral irrigator caused by bumps or drops.

[0063] Preferably, such as Figure 5-7 As shown, the housing 1 includes a first protrusion 12 and a first step 13 extending outward from the bottom edge of the first protrusion 12. In the retracted state, the first abutting surface S1 of the first protrusion 12 is in limiting contact with the second abutting surface S2 of the water tank 101, and the water tank 101 of the water tank 100 completely houses and covers the first protrusion 12. The first step 13 has a surrounding edge 131 extending towards the bottom edge. The surrounding edge 131 is integrally formed with the housing 1. The bottom cover 4 is located inside the surrounding edge 131 and abuts against the bottom end of the first step 13. This structural design makes the bottom cover 4 hidden inside the housing 1 from the overall appearance, making the housing 1 more concise, beautiful and layered in appearance.

[0064] Since most countertop water flossers on the market are placed on the washbasin countertop, and countertop space is limited, overly large water flossers not only take up space and affect the user experience, but are also difficult to store after long-term inactivity or use. Furthermore, exposure to a humid environment can easily lead to moisture damage to the internal components and bacterial growth. Therefore, this utility model has a specific design to reduce the space required for water flosser placement. Specifically, in one embodiment of this utility model, the cross-sections of the main unit 200 and the water tank 100 are both right-angled triangles, each including two right-angled surfaces 121 and an inclined surface 122. The space between the two right-angled surfaces 121 and between the two right-angled surfaces 121 and the inclined surface 122 is... With rounded corners, both the storage slot 51 and the storage opening 1222 are located on the inclined surface 122 of the main unit 200. Compared to the two right-angled surfaces 121, the inclined surface 122 has a larger area and a longer extension. In use, its right-angled triangular shape allows it to be placed close to a corner of the wall. The two right-angled surfaces 121 are respectively attached to two right-angled walls, which can make full use of the corner space, reduce the area occupied on the countertop, and avoid affecting the use of other items on the countertop. The inclined surface 122 faces the user's position, and the storage slot 51 and the storage opening 1222 are set here, which significantly improves the convenience for the user to pick up, put down and operate the main body 2 of the oral irrigator.

[0065] Furthermore, the two right-angled sides of the first step 13 abut against the two adjacent right-angled walls respectively. This fitting method naturally forms a recessed space between the two right-angled surfaces 121 of the housing 1 and the corresponding walls. An avoidance groove 17 is provided at the right-angled bend where the two right-angled surfaces 121 of the housing 1 intersect. A power inlet hole 171 is provided in the avoidance groove 17. The power inlet hole 171 and the inclined surface 122 where the water flosser body 2 is located are on different sides, which can prevent water droplets from splashing onto the power inlet hole 171 and causing leakage when using the water flosser body 2. The recessed space formed by the first step 13 abutting against the wall provides a natural routing channel for the connected power cord. This integrated design achieves two goals at once: it ensures that the main unit 200 can be placed close to the corner of the wall to maximize the saving of countertop space, and it cleverly uses the space formed by the structure to solve the practical problems of power access and wiring, reflecting a high degree of space utilization efficiency and practicality.

[0066] Specifically, since the depth and inner wall contour of the positioning groove 102 and the water storage tank 101 are designed to fit and sleeve with the outer wall of the main unit 200, in one embodiment of this utility model, the groove depth of the positioning groove 102 is C, C=14mm. While ensuring that the water tank 100 can be sleeved and secured to the top of the housing 1, the groove depth C of the positioning groove 102 is minimized as much as possible. The smaller the groove depth C, the smaller the storage height after the water tank 100 is inverted to cover the main unit 200, thus reducing storage space. The water storage depth of the water storage tank 101 is E, E=82mm. The larger the water storage depth E, the larger the water storage capacity of the water storage tank 101, but at the same time, the larger the storage height. In this embodiment, the... The ratio of the water storage depth E of the water tank 101 to the groove depth C of the positioning groove 102 is greater than or equal to 4, i.e., E / C≥4; the height of the first boss 12 of the housing 1 is F, F=83mm. The larger the height F, the larger the volume of the receiving cavity 14, and the larger the height of the main unit 200 will be. It can be seen that the water storage depth E=82mm of the water tank 101 is less than and close to the height F=83mm of the first boss 12. The groove depth E is less than the height F to ensure that the height after storage is not too high. The water storage depth E is close to the height F, which can maximize the water storage capacity of the water tank 101, and also ensure that the water tank 101 can cover the main unit 200. A balance is achieved among these three factors, i.e., C. <E<=F。

[0067] Furthermore, in one embodiment of this utility model, the vertical cross-sectional groove shapes of the water storage tank 101, the positioning groove 102, and the first boss 12 are all trapezoidal. In the stored state, the groove shapes of the water storage tank 101 and the first boss 12 are regular trapezoids, while the groove shape of the positioning groove 102 is an inverted trapezoid. This design ensures that the first boss 12 precisely matches the trapezoidal inner cavity of the water storage tank 101 (stored state) or the positioning groove 102 (used state). Simultaneously, from... Figure 6 As can be seen, although the water storage tank 101 and the positioning groove 102 of the water tank 100 are trapezoids of opposite directions, their outer walls are smoothly transitioned and extend on the same straight line, ensuring the simplicity and beauty of the appearance. In addition, the straight line is also inclined and, combined with the horizontal dotted line in the figure, is trapezoidal. This design makes it easier to demold the mold used to produce the water tank 100 and improves production efficiency.

[0068] Preferably, such as Figure 7-8 As shown, when the housing 1 is connected to the water storage tank 101 or the positioning groove 102, a storage space is provided between the outer peripheral wall of the housing 1 and the inner peripheral wall of the water storage tank 101 or the positioning groove 102. The width of the storage space is G, and the width G=1mm. This effectively avoids scratch damage to the surface of the components during the fitting process, reduces friction, and prevents scratching of the housing 1.

[0069] Furthermore, such as Figure 9-10 As shown, the housing 1 also includes several mounting posts 15 and sleeves 16. The storage assembly 5 is located between the mounting posts 15 and the inclined surface 122 of the housing 1. The sleeves 16 are fitted onto the mounting posts 15 to fill the gap between the storage assembly 5 and the mounting posts 15. The mounting posts 15 are fixedly connected to or integrally formed with the interior of the housing 1. The position of each mounting post 15 corresponds to the outer wall of the storage assembly 5 after installation, forming the installation position of the storage assembly 5. After component 5 is installed, a certain gap remains between it and each of the mounting posts 15. This gap facilitates easy installation of the storage component 5 into the receiving cavity 14. Next, a sleeve 16 adapted to the mounting post 15 is inserted, with the sleeve 16 abutting between the mounting post 15 and the storage component 5. This ensures that the storage component 5 remains in close contact with the inner wall of the inclined surface 122 of the housing 1, preventing water from seeping into the housing 1 from the storage opening 1222 and ensuring the airtightness of the housing 1. In this embodiment, four mounting posts 15 are provided, evenly distributed along the length of the storage component 5 to ensure balanced force distribution and a tight seal.

[0070] Preferably, the sleeve 16 is a rigid body, so that when the sleeve 16 is squeezed, the sleeve 16 can maintain its shape stability under pressure, avoiding deviation of the position of the storage component 5 due to deformation.

[0071] Specifically, such as Figure 10 As shown, the mounting post 15 is a cylindrical tube, and two mutually perpendicular reinforcing ribs 151 are provided on the mounting post 15 to enhance the structural strength, stability and durability of the mounting post 15 and prevent the mounting post 15 from being bent laterally under the strong compression of the sleeve 16; wherein, one of the reinforcing ribs 151 is arranged parallel to the inclined surface 122, and the other reinforcing rib 151 is arranged on the side away from the inclined surface 122 and is perpendicular to the inclined surface 122, so as to avoid affecting the installation of the storage component 5. Correspondingly, the sleeve 16 is provided with a right-angle slot 161 to avoid the two reinforcing ribs 151. To prevent the sleeve 16 from sliding out of the mounting post 15 through the right-angle slot 161 after long-term use, the top of the sleeve 16 is also provided with a collar 162. The height of the two reinforcing ribs 151 is slightly lower than the height of the mounting post 15, so that after installation, the collar 162 of the sleeve 16 can be fitted onto the mounting post 15 to ensure the stability of the position of the sleeve 16.

[0072] Preferably, the outer wall of the sleeve 16 is further provided with a compression rib 163. The compression rib 163 is arranged perpendicularly to the inclined surface 122 and frictionally abuts against the storage component 5. This can further strengthen the abutment force against the storage component 5, improve the sealing performance, and reduce the wear on the sleeve 16, thereby increasing its service life. The bottom end of the compression rib 163 is provided with a guide bevel. When the sleeve 16 is squeezed into the gap between the mounting post 15 and the storage component 5, the guide bevel can accurately guide the insertion direction of the sleeve 16, reduce adjustment time, and improve installation efficiency.

[0073] Preferably, such as Figure 4 As shown, the end face of the storage component 5 that abuts against the housing 1 is also provided with a rectangular groove with rounded corners. The rectangular groove encloses the storage groove 51. A first sealing ring 54 is provided in the rectangular groove so that after installation, the first sealing ring 54 abuts against the inner wall of the housing 1 to further ensure the sealing between the housing 1 and the storage component 5.

[0074] Furthermore, such as Figure 11-12As shown, during use, the drain hole 103 of the water tank 100 is connected to the water inlet hole 11 of the main unit 200. To improve the sealing of the connection between the drain hole 103 and the water inlet hole 11, a first drain column 105 extends from the drain hole 103 of the water tank 100 into the positioning groove 102. The height of the first drain column 105 does not exceed the groove depth C of the positioning groove 102. The diameter of the hole in the inner wall of the first drain column 105 is larger than the diameter of the drain hole 103, forming a second step 1051 inside the first drain column 105. A one-way valve 106 and an elastic element 107 are installed inside the first drain column 105. The one-way valve 106 is generally in the shape of an "I". The elastic element 107 is sleeved on the one-way valve 106, and its two ends are respectively pressed against the second step. On the lower end face of 1051 and the one-way valve 106, and the upper end of the one-way valve 106 is also fitted with a second sealing ring 1061. The diameter of the outer ring of the second sealing ring 1061 is larger than the diameter of the drain hole 103. Since the one-way valve 106 has a downward force due to gravity in its natural state, and under the tension of the elastic element 107, the one-way valve 106 and the second sealing ring 1061 can always keep the drain hole 103 closed. When not in use or in storage, the water tank 100 can be directly removed from the main unit 200. At this time, the water inside the water tank 100 will seal the drain hole 103 under the action of the one-way valve 106, so the water inside the water tank 100 will not leak out from the drain hole 103, making it more convenient to use.

[0075] Furthermore, the housing 1 is also provided with a platform support 18, the pump assembly 3 is fixedly connected to the platform support 18, the upper end face of the platform support 18 is provided with a mounting groove 181, the mounting groove 181 corresponds to the position of the drain hole 103, and a second drain column 182 is opened at the bottom of the mounting groove 181. The water inlet pipe 31 of the pump assembly 3 is connected to the second drain column 182, and the storage assembly 5 is provided with a water outlet 52. The water outlet pipe 32 of the pump assembly 3 is connected to the water flosser body 2 through the water outlet 52. The mounting groove 181 is equipped with a filter screen 183 for filtering impurities and ensuring water quality. The filter screen 183 has a second protrusion 184 at its center. In use, the first water jet 105 passes through the water inlet hole 11 and fits into the mounting groove 181, abutting against the filter screen 183. The bottom end of the one-way valve 106 abuts against the second protrusion 184 and is blocked by the second protrusion 184, resulting in an upward reaction force that causes the one-way valve 106 to move upward as a whole. At this time, a water outlet gap 108 is formed between the water outlet hole 103 and the one-way valve 106. Water in the water tank 100 can flow into the main unit 200 through the water outlet gap 108, thereby realizing the connection between the water outlet hole 103, the water inlet hole 11, and the water inlet pipe 31. The connection structure is simple and the operation is more convenient.

[0076] Preferably, the bottom of the water tank 100 is inclined around the drain hole 103, which can guide the water in the water tank 100 to flow out of the drain hole 103, increasing the flow rate, and also ensure that all the water in the water tank 100 is naturally drained out, making it easy to clean.

[0077] Furthermore, such as Figure 4 , Figure 9 and Figure 18 As shown, the storage assembly 5 is provided with a water outlet 52, which connects the storage groove 51 and the interior of the housing 1. A flexible hose 8 is connected to the tail end of the water flosser body 2. The water outlet pipe 32 of the pump assembly 3 is connected to the flexible hose 8 of the water flosser body through the water outlet 52, thereby connecting the water flosser body 2 and the pump assembly 3. To ensure the sealing of the water outlet 52, a first sealing element 53 is provided at the water outlet 52. The first sealing element 53 is screwed and fixed to the storage assembly 5, and is used to seal the gap between the water outlet 52 and the connection between the flexible hose 8 and the water outlet pipe 32.

[0078] Furthermore, such as Figure 13-14As shown, a power inlet sealing assembly 7 is also provided at the power inlet hole 171. The sealing assembly 7 is used to close the gap between the power inlet hole 171 and the inside of the housing 1. The sealing assembly 7 includes a plug 71, a power terminal 72, and a second sealing member 73. The plug 71 is provided with a mounting cavity 711 that communicates with the power inlet hole 171. The other side of the mounting cavity 711 communicates with the inside of the housing 1. The power terminal 72 is located inside the mounting cavity 711 to close the side of the mounting cavity 711 that communicates with the inside of the housing 1. The second sealing member 73 is tightly abutted between the power inlet hole 171 and the power terminal 72 to seal the gap between the power inlet hole 171 and the mounting cavity 711. The power terminal 72 is provided with a connection port 721 corresponding to the power inlet hole 171, and the second sealing member 73 is provided with a through hole 731 corresponding to the power inlet hole 171, so that the wire can enter the connection port 721 through the power inlet hole 171 and the through hole 731 and connect with the power terminal 72 to realize electrical connection.

[0079] Specifically, the housing 1 is further provided with a slot 142, which is adapted to the shape of the insert 71. The upper end face of the insert 71 is provided with a positioning platform 713 and a positioning hole 712. The housing 1 is provided with a positioning block 143 corresponding to the positioning hole 712. The end face of the positioning platform 713 is perpendicular to the insertion direction of the insert 71. When assembling the sealing assembly 7, the second sealing member 73 first abuts against the power terminal 72. Then, the power terminal 72 and the second sealing member 73 are inserted into the mounting cavity 711 from the side of the mounting cavity 711 that communicates with the power inlet hole 171 to realize the assembly of the internal structure of the sealing assembly 7. Then, the insert 71 is inserted into the opening of the housing 1 and inserted in a direction perpendicular to the host 200. Within the slot 142, the positioning hole 712 engages and is fixed with the positioning block 143. The positioning platform 713 abuts against the inner wall edge of the housing 1. The insertion block 71 is blocked by the positioning platform 713, which can limit and fix the insertion block 71 in the vertical direction. The slot 142 can limit and fix the insertion block 71 in the horizontal direction, ensuring the stability of the connection structure between the insertion block 71 and the housing 1. The positioning block 143 can prevent the insertion block 71 from shifting due to its own structure, and exerts a pulling force on the insertion block 71 towards the positioning platform 713, ensuring that the insertion block 71 is subjected to balanced force. After assembly, the outer wall of the second sealing member 73 abuts tightly against the inner wall of the housing 1, thereby achieving the effect of sealing the power inlet hole 171.

[0080] Preferably, such as Figure 15As shown, in order to improve the user experience of using the water flosser, the main unit 200 is also provided with an indicator light assembly 6. The indicator light assembly 6 is located in the housing 1 on the side near the inclined surface 122. The inclined surface 122 is provided with a light-transmitting hole 1221 corresponding to the indicator light assembly 6, so that the user can easily observe the status of the indicator light assembly 6 when using it.

[0081] Specifically, the indicator light assembly 6 includes, from the inside out, a lamp circuit board 61, a light-shielding sealing member 62, and a light guide plate 63. The lamp circuit board 61 is provided with a plurality of lamp beads 611. The light-shielding sealing member 62 and the light guide plate 63 are respectively provided with light leakage holes 621 and light guide pillars 631 corresponding to the lamp beads 611. During assembly, the light guide pillars 631 are located inside the light-transmitting holes 1221. The light emitted by the lamp beads 611 shines on the light guide pillars 631 through the light leakage holes 621. The setting of the light leakage holes 621 can concentrate the light emitted by the lamp beads 611 into the light leakage holes 621, ensuring efficient light transmission and balanced light emission of the light guide pillars 631.

[0082] Furthermore, the inner wall of the housing 1 is also provided with an inlay groove 19, the light-transmitting hole 1221 is located at the bottom of the inlay groove 19 and penetrates the bottom of the groove, an inlay post 191 is provided in the inlay groove 19, and the light guide plate 63 is provided with an inlay hole 632 corresponding to the inlay post 191. During assembly, the light guide post 631 is inserted into the light-transmitting hole 1221, and the inlay post 191 is fitted into the inlay hole 632. The connection between the light guide plate 63 and the housing 1 is achieved by the snap-fit ​​between the inlay post 191 and the inlay hole 632. The light-shielding sealing member 62 is located between the lamp assembly circuit board 61 and the light guide plate 63. The light-shielding sealing member 62 is tightly abutted between the lamp assembly circuit board 61 and the light guide plate 63 by the screw connection between the lamp assembly circuit board 61 and the housing 1.

[0083] Preferably, the light-shielding seal 62 is made of soft rubber, which has stronger friction and can ensure that it is not easily displaced. At the same time, the setting of the light-shielding seal 62 also realizes the sealed connection between the light-transmitting hole 1221 and the host 200, thereby enhancing the waterproofness of the host 200.

[0084] Furthermore, such as Figure 4As shown, the housing 1 also has a main circuit board 141, which is mounted on the storage component 5 and electrically connected to the water flosser body 2 and the pump component 3. The main circuit board 141 is signal connected to the lamp circuit board 61. After the main circuit board 141 generates a drive signal, the lamp circuit board 61 can convert the electrical signal into a light signal after receiving the drive signal, so as to realize the on / off of different lamp beads 611, making it convenient for users to observe the usage status and mode of the water flosser.

[0085] Preferably, such as Figure 16-17 As shown, in one embodiment of this utility model, the bottom cover 4 has an upwardly protruding triangular convex surface 41 in the middle, and the pump assembly 3 is installed on the convex surface 41. Correspondingly, the bottom cover 4 forms a concave surface opposite to the bottom of the housing 1, which corresponds to the convex surface 41. This structure raises the height of the pump assembly 3 in the main unit 200 from the platform, forming a physical isolation, effectively preventing water on the platform from seeping into the main unit 200, avoiding short circuits or damage, and allowing the pump assembly 3 to remain dry.

[0086] Furthermore, the bottom cover 4 has a raised edge at its edge, and a drainage ditch 42 is provided between the raised edge and the raised surface 41. The drainage ditch 42 is triangular and is connected in a circle around the perimeter. The drainage ditch 42 is provided with drainage holes 421. The drainage holes 421 are only provided in the sections of the drainage ditch 42 corresponding to the two right-angled sides. Two sets of drainage holes 421 are symmetrically provided in each right-angled side section. Each set of drainage holes 421 consists of 3 holes. When using the water flosser, the splashed water or condensed water is quickly collected in the drainage ditch 42, and the water is efficiently discharged through the symmetrically distributed drainage holes 421, effectively preventing water from accumulating on the inner surface of the bottom cover 4.

[0087] Preferably, in one embodiment of this utility model, the bottom cover 4 is provided with four symmetrically distributed screw holes 43, and each screw hole 43 is embedded with an anti-slip pad 431. The anti-slip pad 431 has a preset height, which on the one hand provides stable anti-slip to ensure that the equipment is placed firmly on the table, and on the other hand, its preset height further increases the overall clearance between the bottom cover 4 and the table. In combination with the convex surface 41 structure, it more effectively isolates the table surface moisture and enhances the dry environment at the bottom of the host 200. The bottom cover 4 is also provided with five symmetrically arranged screw holes 44, and each screw hole 44 is provided with a decorative round sticker 441 to cover the screw hole 44 and improve the visual aesthetics and integrity of the bottom of the bottom cover 4.

[0088] Furthermore, such as Figure 18-19As shown, the main body 2 of the water flosser of this utility model includes a handle 21, a connecting rod 22, and a nozzle 23. One end of the connecting rod 22 is detachably or fixedly connected to the nozzle 23, and the other end is detachably or fixedly connected to the handle 21. Correspondingly, the shape of the storage slot 51 of the storage component 5 corresponds to the shape of the handle 21, the connecting rod 22, and the nozzle 23, respectively. The vertical width of the storage slot 51 corresponding to the position of the handle 21 is greater than the vertical width of the handle 21. Since the user holds the handle 21 to operate the water flosser main body 2, the width of the storage slot 51 at this position is set to be wider. This allows the user to insert their fingers into the storage slot 51 to grasp the upper and lower ends of the handle 21 and take it out when using the water flosser main body 2. Therefore, this width design is more practical.

[0089] Specifically, the connecting rod 22 is provided with a water pipe 221, and the handheld part 21 is provided with a water inlet channel 21211. One end of the water inlet channel 21211 is connected to the water pipe 221, and the other end is connected to the hose 8. The water in the water tank 100 passes sequentially through the drain hole 103, the inlet hole 11, and the inlet pipe 31, and under the pressure of the pump assembly 3, passes sequentially through the outlet pipe 32, the hose 8, the inlet channel 21211, the water pipe 221, and the nozzle 23, and is finally pulsed out at the nozzle 23 to rinse the teeth. By designing the water pipe 221 to be completely wrapped and protected by the sturdy connecting rod 22 wall material, it is almost impossible for the water pipe 221 to be flattened or deformed by external forces, ensuring that the water flow channel remains unobstructed under any usage conditions.

[0090] like Figure 20 As shown, it should be noted that in this embodiment, the connecting rod 22 and the mounting plate 231 are integrally formed, which can completely eliminate the interface gap between the connecting rod 22 and the mounting plate 231, eliminating the possibility of water leakage in this part from the root, ensuring that the water flow is transmitted completely according to the design path, and improving the reliability and safety of the product.

[0091] Furthermore, the connecting rod 22 is also provided with a protective shell 223. The protective shell 223 is snapped together with the connecting rod 22 and forms a wire passage between them. The connecting rod 22 is provided with a second circuit board 222. The second circuit board 222 is set in the wire passage, which facilitates the installation of the second circuit board 222 or the power cord, and realizes the water and electricity separation structure in the connecting rod 22, forming protection for the second circuit board 222 or the power cord, and ensuring safety in use.

[0092] Preferably, the nozzle 23 in this embodiment can clean molars, incisors and canines.

[0093] Specifically, such as Figure 21 As shown, the nozzle 23 includes a mounting plate 231 and connecting parts 233 and water spraying parts 232 respectively disposed on both sides of the mounting plate 231. The water spraying part 232 includes a first water spray shell 2321 and a second water spray shell 2322. The first water spray shell 2321 is provided with a rotating column 2323. The mounting plate 231 is provided with a mounting hole 2313 corresponding to the rotating column 2323. The rotating column 2323 is inserted into the mounting hole 2313 so that the first water spray shell 2321 is rotatably connected to the mounting plate 231. Furthermore, such as Figure 22-23 As shown, the first water spray shell 2321 is embedded in the second water spray shell 2322 to form a water spray cavity 234. The mounting plate 231 includes a sliding groove 2311. The sliding groove 2311 is provided with a water outlet 23111 that communicates with the water pipe 221, so that water flows into the nozzle 23. The rotating column 2323 is provided with a water inlet 23231 that communicates with the sliding groove 2311 and the water spray cavity 234. The second water spray shell 2322 is provided with a water spray hole 2324 that communicates with the water spray cavity 234.

[0094] In use, water enters from the end of the handheld part 21 through the water inlet channel 21211, and is transmitted to the water outlet 23111 of the mounting plate 231 via the connecting rod 22. Then, the water flows through the water outlet 23111 into the space formed by the sliding groove 2311 of the mounting plate 231 and the water spray component 232, and flows into the water spray chamber 234 through the water inlet 23231 on the rotating column 2323. Finally, the water in the water spray chamber 234 is sprayed out in a pulsed water jet through the water spray hole 2324 on the second water spray shell 2322 under pressure, achieving effective rinsing of the user's teeth. Compared to traditional single-shell or simple docking cavity forms, this embedded design can create a larger internal space, namely the water spray chamber 234, which can instantly store more water. The larger instantaneous water storage capacity helps to generate a stronger and more stable water flow impact force during pulse jet, improving the cleaning effect. At the same time, the design requires fewer parts, has a relatively simple structure, and the fewer parts and clear connection relationship greatly simplifies the assembly process and reduces production costs. The detachable connection facilitates the replacement of damaged parts or cleaning and maintenance, and the rotatability of the water spray component 232 may also provide a certain degree of angle adjustment flexibility.

[0095] Specifically, a camera unit 235 is embedded on the side of the connector 233 away from the mounting plate 231, and the connector 233 is rotatably connected to the mounting plate 231 to drive the camera unit 235 to rotate.

[0096] Specifically, such as Figure 22-25As shown, the mounting plate 231 also includes a second sliding groove 2312. The connector 233 is provided with a stop block 2331 that is adapted to the second sliding groove 2312. The stop block 2331 is inserted into and slidably connected to the second sliding groove 2312. The camera unit 235, which is fixedly connected to the connector 233, is rotatably connected to the mounting plate 231 along with the connector 233 through the cooperation of the stop block 2331 and the second sliding groove 2312.

[0097] Furthermore, the sliding groove 2312 is C-shaped, and the two ends of the C-shaped groove are closed. When the stop block 2331 slides in the C-shaped groove, its range of motion is strictly limited to the arc length of the C-shaped groove. This design limits the rotation angle of the connector 233 and the camera part 235 on it relative to the mounting plate 231 to within 180 degrees.

[0098] Specifically, the mounting hole 2313 is coaxially arranged with the rotating column 2323. The rotating column 2323 includes a connecting platform 23232. The connector 233 also includes a cantilever mounting platform 2332. The mounting platform 2332 is provided with a connecting groove 23321 that corresponds to the position of the connecting platform 23232 and is adapted in shape, and a connecting hole 23322 that is coaxially arranged with the mounting hole 2313. The rotating column 2323 passes through the mounting hole 2313 on the mounting plate 231 and is inserted into the connecting groove 23321 to achieve a rotational connection between the three. The connector 233, the mounting plate 231 and the rotating column 2323 are screwed together and fixed. The connector 233 and the rotating column 2323, which are screwed together, rotate together around the central axis of the mounting hole 2313, that is, the axis of the rotating column 2323. This rotation is restricted by the stop block 2331 within the C-shaped arc length range of the sliding groove 2312. In use, the rotation of connector 233 directly drives the rotating column 2323 to rotate synchronously, thereby changing the spray direction of the water spray hole 2324; at the same time, the rotation of connector 233 also drives the camera unit 235 on it to rotate synchronously, changing the viewing angle of camera 2352.

[0099] In this embodiment, the connecting platform 23232 is set as a cuboid, but it can also be set as a prism, star-shaped prism, etc. The connecting groove 23321 is set to be adapted to the shape of the connecting platform 23232. At this time, the connecting platform 23232 rotates with the rotation of the connecting member 233, and the water spraying member 232 rotates synchronously with the connecting member 233. That is, the camera unit 235 rotates synchronously with the water spraying member 232. The rotation angle and direction of the water spraying member 232 and the connecting member 233 / camera unit 235 are completely synchronized and limited to 180 degrees.

[0100] Preferably, the connecting platform 23232 can also be set as a cylinder to achieve 360-degree rotation of the connecting platform 23232 relative to the connecting groove 23321. That is, the water spray component 232 can rotate 360 ​​degrees relative to the mounting plate 231 and the connector 233. The water flow direction of the water spray component 232 and the observation angle of the connector 233 / camera unit 235 can be independently and precisely adjusted without interference. At this time, the rotation angle of the connector 233 / camera unit 235 is still strictly limited to within 180 degrees by the C-shaped sliding groove 2312, and the rotation operation is independent of the water spray component 232.

[0101] like Figure 25 As shown, in order to prevent water from the water spray component 232 from overflowing into the sliding groove 2312, a second protrusion 23131 is integrally formed on the mounting hole 2313. The second protrusion 23131 and the inner wall of the mounting hole 2313 form a sealing groove 23132. A sixth sealing ring 23133 is provided in the mounting hole 2313. The sixth sealing ring 23133 is set on the sealing groove 23132 and abuts against the inner wall of the mounting hole 2313. This structure directly blocks the path of water from seeping into the sliding groove 2312 through the gap in the inner wall of the mounting hole 2313, thereby fundamentally preventing water from eroding and damaging the second circuit board 222. Especially when the rotating column 2323 drives the water spray component 232 to move, the seal here needs to be able to adapt to the relative movement.

[0102] Furthermore, the rotating column 2323 also includes a third boss 23233, and a protrusion 23112 is provided on the sliding groove 2311. The protrusion 23112, the third boss 23233, and the outer wall of the rotating column 2323 form a sealing groove 23113. A fifth sealing ring 23114 is provided in the sealing groove 23113. The fifth sealing ring 23114 is disposed between the third boss 23233 and the protrusion 23112 and abuts against the inner wall of the mounting plate 231. By setting the... The third boss 23233 and the protrusion 23112 are provided with a fifth sealing ring 23114 between them to prevent water flowing into the sliding groove 2311 through the water outlet 23111 from leaking outward along the inner wall of the sliding groove 2311. Even when the rotating column 2323 is performing rotation or pitch adjustment, the fifth sealing ring 23114 can still maintain effective sealing contact pressure in the stable cavity formed by the third boss 23233 and the protrusion 23112, adapting to the small gap changes caused by the movement. The boss limiting + protrusion support + sealing cavity structure of this design provides an extremely stable installation environment and working surface for the fifth sealing ring 23114, effectively preventing it from shifting, twisting or excessively wearing under dynamic working conditions.

[0103] Specifically, such as Figure 23 , Figure 26As shown, the camera unit 235 has an extension hole 2351, and a camera 2352 is mounted on the extension hole 2351. The connecting rod 22 also houses a second circuit board 222 electrically connected to the main circuit board 141 inside the host 200. The mounting plate 231 has a wiring groove 23121 independent of the sliding groove 2312. The connector 233 has a movable groove 2333, which corresponds to the wiring groove 23121, for the second circuit board 222 or a power cord to pass through and electrically connect to the camera 2352. A wireless communication module (not shown) is connected to the second circuit board 222 and / or the main circuit board 141. The wireless communication module is connected to a wireless display device (such as a common smartphone APP). When in use, the camera 2352 captures images inside the oral cavity. The signal is processed by the second circuit board 222 and transmitted to the external wireless display device via the wireless communication module. When rinsing the upper teeth, the user can observe the lower teeth and oral environment in real time through the display device. When rinsing the lower teeth, the user can observe the upper teeth and oral environment in real time through the display device, realizing the function of rinsing teeth and imaging inside the oral cavity at the same time. When rinsing is completed, the wireless communication module and the wireless display device (such as a common smartphone APP) can generate an oral and dental health assessment report based on the camera observation.

[0104] Specifically, such as Figure 27-28 As shown, the second water spray shell 2322 is trapezoidal and adapts to the shape of the first water spray shell 2321. The surface of the second water spray shell 2322 is smoothly transitioned, which avoids scratching the oral mucosa and completely eliminates the turbulence and pressure loss caused by the traditional right-angle shell. The water flow is accelerated more smoothly and the spray pressure is significantly improved.

[0105] Preferably, the first water spray shell 2321 and the second water spray shell 2322 can be ultrasonically welded.

[0106] Specifically, such as Figure 28 As shown, the second water spray shell 2322 includes a first side arm 23221 and a second side arm 23222 with water outlets in an inward V-shape. The first side arm 23221 and the second side arm 23222 are symmetrically arranged along the central axis L1 of the water spray component 232. The water spray hole 2324 includes a side spray nozzle 23241. The first side arm 23221 and the second side arm 23222 are both provided with the side spray nozzle 23241. In this embodiment, there are two side spray nozzles 23241 on the first side arm 23221. The number of water spray holes 2324 can be adjusted according to actual needs. The side spray nozzles 23241 on the first side arm 23221 and the second side arm 23222 are symmetrically arranged along the central axis L1. The water lines sprayed from the two side spray nozzles 23241 on the same side are parallel. The design of the side arms 1 (23221) and 2 (23222) with their "inward-pointing" water outlets, along with the side spray nozzles 23241, guides the water flow inward. This symmetrical water flow design allows for the convergence and superposition of water in the central area, forming a more concentrated and powerful core water flow, suitable for cleaning or spraying tasks requiring strong impact. At the same time, it can form a more uniform and wider spray fan around the core water flow, covering a larger area and simultaneously addressing the issues of central impact and edge coverage.

[0107] Furthermore, such as Figures 29-30 As shown, the second water spray shell 2322 also includes a connecting arm 23223, and the water spray hole 2324 also includes a front spray nozzle 23242 disposed on the connecting arm 23223. There are two front spray nozzles 23242, and the two front spray nozzles 23242 are far apart from each other and close to the side edge of the connecting arm 23223. The water line sprays out in an "outward V" shape, which is suitable for rinsing the molar surface deep in the oral cavity. When the side edge of the connecting arm 23223 is close to the deepest molar, the corresponding front spray nozzle 23242 can rinse the deepest molar surface without having to push the side edge of the connecting arm 23223 further into the oral cavity, thus making it more convenient to achieve comprehensive cleaning of the teeth.

[0108] Preferably, such as Figure 26 , Figure 31 As shown, there are two cameras 2352. The camera unit 235 also includes a fixed-focus block 2353 for stabilizing the focal length and reducing interference from water flow and fog. The fixed-focus block 2353 is located between the two cameras 2352. In this embodiment, the camera unit 235 is T-shaped, with the horizontal part accommodating the two cameras 2352 and the vertical part being the fixed-focus block 2353, forming a stable triangular structure that resists water flow impact and shaking. At the same time, the design of the dual cameras 2352 solves the problem of blind spots and frequent angle adjustments required when shooting from the side by a single camera 2352 in traditional designs. The fixed-focus block 2353 located in the middle physically blocks water fog interference between the two cameras 2352 and serves as a focal length reference to improve image consistency.

[0109] Furthermore, the extension direction of the protruding hole 2351 forms an angle A with the central axis L2 of the fixed focus block 2353, that is, the camera 2352 is arranged obliquely, and a single shot can cover the tooth surface and adjacent seams, solving the problem that the traditional vertical viewing angle needs to be adjusted multiple times.

[0110] Preferably, the included angle A is an acute angle, which makes the camera 2352 take better pictures when cleaning teeth, making it easier to observe the dirt on both sides of the teeth and significantly improving the visibility of lateral dental plaque.

[0111] The protrusion hole 2351 is provided with a corresponding mounting block 2354. The camera 2352 is mounted on the mounting block 2354. The mounting block 2354 is provided with a second LED bead 23541. The second LED bead 23541 is arranged around the circumference of the camera 2352. By setting the second LED bead 23541, a uniform light source is provided for the depth of the oral cavity, and clear imaging can be achieved even in dark environments.

[0112] Preferably, such as Figure 20 As shown, due to the convergence of the two cameras 2352, the end of the second circuit board 222 that is electrically connected to the cameras 2352 is V-shaped. The convergence of the cameras 2352 results in the concentration of electrical contacts. The V-shaped end of the circuit board fits the angled layout of the two cameras 2352, reducing redundant space occupation and making the camera part 235 more slender overall, thus avoiding the expansion of the nozzle 23 which affects the flexibility of oral operation.

[0113] Furthermore, such as Figure 19 , Figure 32 and Figure 33 As shown, the handheld part 21 of the main body 2 of the water flosser of this utility model includes a shell 211 and a fixing frame 212 disposed inside the shell 211. The water inlet channel 21211 is disposed inside the fixing frame 212 and integrally formed with the fixing frame 212, so as to enhance the waterproofness, sealing and rigidity of the water flow channel in the handheld part 21. The two ends of the fixing frame 212 are adapted to and abut against the inner wall of the shell 211, so that after assembly, the outer wall of the fixing frame 212 and the inner wall of the shell 211 form a sealed cavity 213. The sealed cavity 213 is provided with a first circuit board 214. The first circuit board 214 is electrically connected to the second circuit board 222 and the main circuit board 141, thereby realizing the water and electricity separation structure in the handheld part 21, and providing a guarantee for the stability and safety of the first circuit board 214.

[0114] Specifically, such as Figure 33As shown, to facilitate the installation of the fixing frame 212 and the outer shell 211, in this embodiment, the fixing frame 212 includes a main support 2121 and a sealing support 2122. One end of the sealing support 2122 is sealed to the main support 2121, and the other end is engaged with the connecting rod 22. The water inlet end of the main support 2121 is provided with a base plate 21212 that is adapted to the inside of the outer shell 211. During assembly, after the water outlet end of the main support 2121 is inserted from one end of the outer shell 211, the base plate 21212 forms a tight abutment with the inner wall of the end of the outer shell 211. This seals one end of the outer casing 211 near the hose 8, and then inserts the sealing bracket 2122 from the other end of the outer casing 211, so that the sealing bracket 2122 and the inner wall of the other end of the outer casing 211 form a tight abutment, thereby sealing the end of the outer casing 211 near the nozzle 23. This allows the sealing bracket 2122, the main bracket 2121, and the outer casing 211 to form the sealing cavity 213, preventing water from seeping into the gaps connecting the water inlet channel 21211 with the outer casing 211 and causing damage to the first circuit board 214.

[0115] Preferably, to ensure the airtight connection between the fixing frame 212 and the outer shell 211, a third sealing ring 2124 and a fourth sealing ring 2125 are respectively fitted at both ends of the fixing frame 212. The third sealing ring 2124 and the fourth sealing ring 2125 are respectively in close contact with the inner wall of the outer shell 211. In this embodiment, the third sealing ring 2124 is fitted at the connection between the sealing bracket 2122 and the outer shell 211, and the fourth sealing ring 2125 is fitted on the base plate 21212 of the main bracket 2121.

[0116] Furthermore, the sealing bracket 2122 is provided with a connecting pipe 2123 extending toward the water inlet channel 21211. The connecting pipe 2123 is located inside the water inlet channel 21211 and is in close contact with the inner wall of the water inlet channel 21211. One end of the water passage pipe 221 inside the connecting rod 22 is connected to the nozzle 23, and the other end is inserted into the connecting pipe 2123 and forms a tight contact with the inner wall of the connecting pipe 2123, thereby realizing the connection between the water passage pipe 221 and the water inlet channel 21211. After assembly, to enhance the tightness of the connection between the connecting pipe 2123 and the water inlet channel 21211 and prevent water leakage, several sealing rings are also fitted on the connecting pipe 2123. The sealing rings are tightly abutted against the inner wall of the water inlet channel 21211 to form a multi-layer leak-proof structure. After the sealing bracket 2122 is connected to the main bracket 2121, the sealing bracket 2122 and the main bracket 2121 can be screwed together and fixed with screws to make the connection between the two more stable.

[0117] Preferably, the outer shell 211 has an elongated slot 2111 along the axial direction, and the main support 2121 has a plate 21213 adapted to the slot 2111. The plate 21213 is integrally formed with the main support 2121. During installation, the plate 21213 is located in the slot 2111 and is slidably connected to the slot 2111, so that the main support 2121 is limited and fixed in the outer shell 211, preventing the main support 2121 from rotating in the outer shell 211 and improving the stability of the connection between the main support 2121 and the outer shell 211. At the same time, by providing integrally formed plates 21213 on both sides of the main support 2121, the rigidity of the structure of the main support 2121 and the outer shell 211 can also be enhanced, avoiding deformation of the internal structure when subjected to external impact.

[0118] Furthermore, since the first circuit board 214 is disposed within the sealed cavity 213, in order to achieve electrical connection between the first circuit board 214 and the camera unit 235 and the main circuit board 141, both the sealed bracket 2122 and the main bracket 2121 are provided with wire passage holes 215. A wire passage sealing element 2151 is provided within the wire passage hole 215 to seal the gap between the wire and the wire passage hole 215, thereby improving the sealing performance of the sealed cavity 213. The wire passage hole 215 on the sealed bracket 2122 is positioned vertically higher than the water outlet end face of the connecting pipe 2123. Even if a small amount of water leaks out, it will not seep into the sealed cavity 213 through the wire passage hole 215, further enhancing the waterproof performance of the handheld part 21.

[0119] Furthermore, such as Figure 34 As shown, the main support 2121 is also provided with a plurality of fixing members 21214. The fixing members 21214 are used to install the first circuit board 214. In this embodiment, the fixing members 21214 are disposed on the plate 21213, and the fixing members 21214 can be positioning posts or screw holes. The first circuit board 214 is provided with fixing holes (not shown in the figure) that are adapted to the fixing members 21214. The connection and fixation of the first circuit board 214 and the main support 2121 are realized through the connection of the fixing holes and the fixing members 21214.

[0120] Specifically, the outer casing 211 is provided with a plurality of buttons 2112. In this embodiment, the buttons 2112 include an on / off switch for starting and stopping the water flosser body 2, and an up / down adjustment switch for adjusting the water flow speed. The buttons 2112 are electrically connected to the first circuit board 214. A circuit board seal 2113 is also provided between the buttons 2112 and the first circuit board 214 to seal the connection gap between the buttons 2112 and the outer casing 211. The circuit board seal 2113 is made of elastic material. When the buttons 2112 are pressed, the buttons 2112 can automatically reset under the action of the circuit board seal 2113, thereby sealing the gap between the buttons 2112 and the outer casing 211 when pressed, ensuring the airtightness of the outer casing 211.

[0121] Furthermore, such as Figures 35-36 As shown, the water inlet end of the water inlet channel 21211 is provided with a docking cavity 21215 facing the inner side of the hose 8. A docking plug 26 is installed in the docking cavity 21215. The other end of the docking plug 26 is connected to the hose 8. A seventh sealing ring 261 is fitted on the end of the docking plug 26 that is connected to the docking cavity 21215 to prevent liquid leakage.

[0122] Furthermore, at the connection between the hose 8 and the main support 2121, a detachable support member 1 216 and a support member 217, each set in half, are fitted. The support member 1 216 and the support member 217 together enclose the connection between the docking plug 26 and the hose 8, enhancing the stability of the connection and preventing the hose 8 from separating from the docking plug 26 during use. Each support member 1 216 and support member 217 has an inner support member 2161 and an outer support member 2162. The two inner support members 2161 form a "C" shape to jointly enclose the connection between the docking plug 26 and the hose 8. The outer support member 2162 has a screw hole for connection to the main support 2121. The main support 2121 has a screw post corresponding to the screw hole. The connection between the support member 1 216, the support member 217, and the main support 2121 is achieved through the screwing of the screw hole and the screw post.

[0123] Preferably, the inner support member 2161 has a wire-passing opening 21611, which allows the wires inside the host 200 to pass through the wire-passing opening 21611, through the wire-passing hole 215, and into the outer casing 211 to achieve electrical connection with the first circuit board 214. In this embodiment, there are four wires: two for connecting the button 2112 and the other two for connecting the camera unit 235.

[0124] Preferably, such as Figure 18 As shown, to improve the convenience of using the water flosser body 2, the hose 8 has a retractable telescopic section 81. In use, the telescopic section 81 is at least partially stretched out of the cable groove 511. By stretching, the user can straighten the telescopic section 81 to extend the length of the hose 8, thereby increasing the usable range of the water flosser body 2 and improving ease of use. When the hose 8 is not under tension, the telescopic section 81 of the hose 8 can naturally retract to improve the neatness of storage, reduce storage space, and, more importantly, prevent the hose 8 from bending and wearing down, thus reducing its service life. Correspondingly, the storage groove 51 is provided with an inwardly extending circular cable placement groove 511, which is adapted to the telescopic section 81 of the hose 8, so that the hose 8 can be rolled up and stored in the cable placement groove 511; and the water outlet 52 of the storage component 5 is located in the cable placement groove 511, which facilitates shortening the distance between the water outlet pipe 32 of the pump component 3 in the main unit 200 and the telescopic section 81 of the hose 8, and optimizes the layout of the internal structure.

[0125] Preferably, such as Figure 19 As shown, the handheld part 21 is further provided with a top cover 24 and a tail cover 25 at both ends. The top cover 24 encloses both the connecting rod 22 and the sealing bracket 2122 and is snapped and fixed to the connecting rod 22. The tail cover 25 encloses both the first support member 216 and the second support member 217 and is snapped and fixed to them. This makes the overall appearance of the water flosser body 2 more aesthetically pleasing and improves the user experience. The snap-fit ​​structure here is a conventional operation in the prior art, so it will not be described in detail here.

[0126] Furthermore, such as Figures 37-38As shown, the handheld part 21 of the main body 2 of the water flosser of this utility model is also provided with a drainage structure. The drainage structure includes a first magnet 27 and a second magnet 28 disposed in the outer shell 211. Two second magnets 28 are symmetrically arranged. The main bracket 2121 is provided with a first fixing position 21216 for installing the first magnet 27. The first fixing position 21216 is located on the opposite side of the first circuit board 214 to avoid conflict with the first circuit board 214. The position of the first fixing position 21216 is also in line with the user's use of the water flosser. The gripping posture when using the main body 2 is the same as when storing the main body 2, improving the convenience of use; and the first fixing position 21216 is located in the middle position of the main body 2 along the axial direction, while the tail cap 25 is provided with a second fixing position 251 for installing the two second magnets 28. By setting the second fixing position 251 on the tail cap 25, the first magnet 27 and the two second magnets 28 form a triangular magnetic attraction structure, which ensures the overall balance of the main body 2 when suspended, and makes it more stable when magnetically fixed and less likely to fall off; The first magnet 27 is much larger than the second magnet 28, which gives the center of the water flosser body 2 a stronger attraction, preventing the water flosser body 2 from easily falling off and being damaged by collision, ensuring its suspension stability and extending its service life.

[0127] Preferably, such as Figure 9 As shown, the storage component 5 is provided with magnetic suction members 9 corresponding to the first magnet 27 and the two second magnets 28 respectively. When the water flosser is not in use, the water flosser body 2 can be horizontally magnetically suspended and stored in the storage groove 51, which facilitates the draining of water from the water flosser body 2 and improves the service life of the water flosser body 2.

[0128] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.

[0129] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
