Detailed Implementation

[0025] The following is for reference. Figures 1-4 The main unit of a handheld oral irrigator 100 according to a first aspect embodiment of the present invention is described.

[0026] like Figures 1-4 As shown, the main unit of the handheld oral irrigator 100 according to the first aspect embodiment of the present invention includes: a housing 10, a water pump assembly 20, and a circuit board assembly 30.

[0027] Specifically, the housing 10 has a receiving cavity, in which a water pump assembly 20 is disposed, and the water pump assembly 20 is adapted to be connected to the water tank 60 via a water inlet pipe. A circuit board assembly 30 is disposed in the receiving cavity and is electrically connected to the water pump assembly 20.

[0028] For example, in Figures 1-3 In the example, the nozzle 70 and the water tank 60 are respectively located in the height direction of the main unit (e.g., Figure 1 On both sides (up and down direction) of the main unit, the inlet end of the nozzle 70 is connected to the outlet of the water pump assembly 20, and the inlet of the water pump assembly 20 is connected to the water tank 60 through a water inlet pipe. The water pump assembly 20 and the circuit board assembly 30 can be connected along the thickness direction of the main unit (e.g., along the thickness direction). Figure 1 The front and back directions are arranged in the receiving cavity of the housing 10. When the handheld oral irrigator 100 is working, the water pump assembly 20 pumps water from the water tank 60 to the nozzle 70 through the water inlet pipe, and sprays the water out through the outlet end of the nozzle 70 to rinse the teeth, thus completing the cleaning work.

[0029] The circuit board assembly 30 features a DIY mode with at least five pressure settings, each with a different water pressure. In other words, the handheld water flosser 100 has at least five pressure settings in DIY mode, each with a different water pressure. This allows individuals with sensitive mouths or teeth to use a lower water pressure setting, those requiring deep cleaning to use a higher water pressure setting, and those without special needs to use a moderate water pressure setting.

[0030] This setting increases the range of water pressure values ​​for the handheld water flosser 100, enabling it to meet the needs of special groups, improving its applicability, and providing users with a better user experience.

[0031] The main unit of the handheld water flosser 100 according to an embodiment of the present invention features a DIY mode on its circuit board assembly 30, with at least five different water pressure settings for each setting. Therefore, compared to traditional handheld water flossers, the handheld water flosser 100 of this application has a wider range of water pressure values, meeting the needs of specific user groups, improving its applicability, and providing a better user experience.

[0032] According to some embodiments of this utility model, the water pressure value of the circuit board assembly 30 in DIY mode is P, where P satisfies: 10PSI≤P≤100PSI. When P<10PSI, the water pressure value of the handheld water flosser 100 is relatively small, that is, the impact force of the water jet from the nozzle 70 is relatively small, resulting in the handheld water flosser 100 being unable to effectively clean the user's teeth; when P>100PSI, the water pressure value of the handheld water flosser 100 is relatively large, that is, the impact force of the water jet from the nozzle 70 is relatively large, which may cause damage to teeth and gums, affecting the user's experience. Therefore, by setting the water pressure value between 10PSI and 100PSI, the handheld water flosser 100 has a wide range of water pressure values, ensuring that teeth are thoroughly cleaned while meeting the needs of different users.

[0033] Furthermore, the DIY mode includes a first sub-mode, a second sub-mode, a third sub-mode, and a fourth sub-mode. The water pressure value of the first sub-mode is P1, the water pressure value of the second sub-mode is P2, the water pressure value of the third sub-mode is P3, and the water pressure value of the fourth sub-mode is P4. Among them, P1, P2, P3, and P4 satisfy the following conditions: 10PSI≤P1≤30PSI, 30PSI<P2≤50PSI, 50PSI<P3≤80PSI, and 80PSI<P4≤100PSI.

[0034] Thus, the first sub-mode has a lower water pressure, which is suitable for people with sensitive mouths or teeth to rinse their teeth in the first sub-mode; the second sub-mode has a moderate water pressure, and the water jet from nozzle 70 has a relatively gentle impact, allowing the handheld oral irrigator 100 to gently rinse the teeth; the third sub-mode has a relatively higher water pressure, and the water jet from nozzle 70 has a relatively stronger impact, which is suitable for people without special needs to rinse their teeth in the third sub-mode; the fourth sub-mode has a higher water pressure, and the water jet from nozzle 70 has a stronger impact, which is suitable for people who need deep cleaning or orthodontic treatment to rinse their teeth thoroughly.

[0035] According to some specific embodiments of this utility model, the first sub-mode includes a first gear, a second gear, and a third gear. The water pressure value of the first gear is p1, the water pressure value of the second gear is p2, and the water pressure value of the third gear is p3. p1, p2, and p3 respectively satisfy: 10PSI≤p1≤15PSI, 15PSI<p2≤25PSI, and 25PSI<p2≤35PSI. Specifically, the water pressure value of the first gear can be 10PSI, the water pressure value of the second gear can be 20PSI, and the water pressure value of the third gear can be 30PSI. This allows the first sub-mode to have a wide range of water pressure values, making the handheld oral irrigator 100 suitable for people with varying degrees of oral or dental sensitivity, further improving the applicability of the handheld oral irrigator 100.

[0036] According to some specific embodiments of this utility model, the second sub-mode includes a fourth pressure setting and a fifth pressure setting. The water pressure value of the fourth pressure setting is p4, and the water pressure value of the fifth pressure setting is p5. p4 and p5 respectively satisfy: 35PSI < p4 ≤ 45PSI and 45PSI < p5 ≤ 55PSI. Specifically, the water pressure value of the fourth pressure setting can be 40PSI, and the water pressure value of the fifth pressure setting can be 50PSI. Therefore, the second sub-mode has two different water pressure settings, allowing the handheld oral irrigator 100 to have two gentle water flow modes, thus meeting the usage needs of different users.

[0037] According to some specific embodiments of this utility model, the third sub-mode includes a sixth, a seventh, and an eighth pressure setting. The water pressure value of the sixth pressure setting is p6, the water pressure value of the seventh pressure setting is p7, and the water pressure value of the eighth pressure setting is p8. Specifically, p6, p7, and p8 satisfy the following conditions: 55PSI < p6 ≤ 65PSI, 65PSI < p7 ≤ 75PSI, and 75PSI < p7 ≤ 85PSI, respectively. The water pressure value of the sixth pressure setting can be 60PSI, the water pressure value of the seventh pressure setting can be 70PSI, and the water pressure value of the eighth pressure setting can be 80PSI. Therefore, the third sub-mode has a wide range of water pressure values, allowing the handheld oral irrigator 100 to meet the usage needs of most people.

[0038] According to some specific embodiments of this utility model, the fourth sub-mode includes a ninth level and a tenth level. The water pressure value of the ninth level is p9, and the water pressure value of the tenth level is p10. p9 and p10 respectively satisfy: 85PSI < p9 ≤ 95PSI, 95PSI < p10 ≤ 100PSI. Specifically, the water pressure value of the ninth level can be 90PSI, and the water pressure value of the tenth level can be 100PSI. This configuration allows the handheld oral irrigator 100 to have a large water flow impact force, enabling deep cleaning for users or meeting the needs of orthodontic patients.

[0039] According to some embodiments of this utility model, the circuit board assembly 30 further includes a gentle mode, a clean mode, and a massage mode. The water pressure value of the gentle mode is consistent with the water pressure value of the second sub-mode, and / or the water pressure value of the clean mode is consistent with the water pressure value of the third sub-mode. For example, the water pressure value of the gentle mode may be consistent with the water pressure value of one of the two settings of the second sub-mode, and the water pressure value of the clean mode may be consistent with the water pressure value of one of the three settings of the third sub-mode.

[0040] Therefore, when the control logic of the gentle mode and / or clean mode in the circuit board assembly 30 is damaged, the water pressure value of the gentle mode and / or clean mode can be realized through the gear in the DIY mode, which can improve the service life of the handheld oral irrigator 100 and reduce maintenance costs.

[0041] In some optional embodiments, when the circuit board assembly 30 is in massage mode, the water output frequency of the main unit is f, where f satisfies: 1400 times / min ≤ f ≤ 1800 times / min. That is, in massage mode, the handheld water flosser 100 generates pulsed water flow, and the handheld water flosser 100 outputs water intermittently. With this setting, in massage mode, by controlling the water output frequency of the handheld water flosser 100 between 1400 times / min and 1800 times / min, the water pump assembly 20 can generate high-pressure pulsed water flow, and the impact force of the water flow is appropriate. The high-pressure pulsed water flow can effectively clean food debris and plaque from the tooth surface and between teeth.

[0042] Furthermore, the main unit of the handheld oral irrigator 100 also includes a first button 40 and a second button 50. The first button 40 is located on the housing 10, and one end of the first button 40 is adapted to contact the first touch control 301 of the circuit board assembly 30, for controlling the circuit board assembly 30 to switch to DIY mode. The second button 50 is located on the housing 10 and below the first button 40, and one end of the second button 50 is adapted to contact the second touch control 302 of the circuit board assembly 30, for controlling the circuit board assembly 30 to switch to gentle mode, cleaning mode, or massage mode.

[0043] Reference Figures 1-3 The main unit also includes a power switch 51. The power switch 51, the first button 40, and the second button 50 are all located on the same side of the main unit's thickness direction, and are arranged along the height direction of the main unit. The first button 40 is located between the power switch 51 and the second button 50. Users can press the first button 40 to electrically connect the first touch control 301 to the circuit board of the circuit board assembly 30, allowing them to select any of the 10 settings in the DIY mode for teeth rinsing. Alternatively, users can press the second button 50 to electrically connect the second touch control 302 to the circuit board, allowing them to select a gentle mode, a clean mode, or a massage mode for teeth rinsing.

[0044] In this configuration, at least a portion of the surface of the first button 40 on the side away from the housing 10 is recessed toward the housing 10, and / or the surface of the first button 40 on the side away from the housing 10 is provided with a protrusion 41, the protrusion 41 extending circumferentially along the first button 40. For example... Figures 1-3 As shown, the surface of the first button 40 away from the housing 10 is a concave surface. The concave surface increases the contact area between the first button 40 and the user's finger, making it easier for the user to press the first button 40 and making the force on the first button 40 more even. The concave surface is provided with a plurality of protrusions 41, which are spaced apart along the direction from the center of the first button 40 to its edge. The protrusions 41 can increase the tactile sensitivity between the first button 40 and the user's finger, making it easier for the user to press the first button 40 accurately during use.

[0045] Optionally, each protrusion 41 can be a complete annular protrusion (not shown in the figure); or, each protrusion 41 can also be composed of multiple protrusion segments, which are spaced apart circumferentially along the first button 40 (e.g., Figure 1 (As shown).

[0046] Specifically, refer to Figure 3 and Figure 4 A mounting hole 101 is formed on one side wall of the housing 10 in the thickness direction. A support member 90 is provided in the mounting hole 101. Three clearance grooves 91 are formed on the side of the support member 90 away from the housing 10. The three clearance grooves 91 are respectively opposite to the switch button 51, the first button 40 and the second button 50. A pressing part 92 is provided in each clearance groove 91. One end of the pressing part 92 contacts the corresponding button, and the other end of the pressing part 92 contacts the corresponding touch control, so that the user can control the working state of the handheld oral irrigator 100 by pressing different buttons.

[0047] like Figures 1-3 As shown, the handheld oral irrigator 100 according to the second aspect embodiment of the present invention includes the main unit of the handheld oral irrigator 100 according to the first aspect embodiment of the present invention.

[0048] According to the present utility model embodiment, the handheld water flosser 100, by adopting the above-mentioned host, can improve the applicability of the handheld water flosser 100, thereby improving the market competitiveness of the handheld water flosser 100.

[0049] According to some embodiments of the present invention, the handheld water flosser 100 also includes a display screen 80, which is disposed between the main unit and the water tank 60 and electrically connected to the circuit board of the circuit board assembly 30. The display screen 80 displays the operating mode and battery level of the handheld water flosser 100 to the user, so that the user can intuitively understand the status of the handheld water flosser 100.
