Description

Technical Field

[0001] This disclosure relates to the technical field of cleaning appliances, and particularly to an oral care device, oral care equipment, and grip housing. Background Technology

[0002] To facilitate the cleaning of residual limescale, bacteria, or impurities inside the water tank of a water flosser, a removable bottom cover is usually inserted at the bottom of the water flosser, allowing users to easily open the bottom cover for thorough cleaning.

[0003] Meanwhile, to ensure a tight seal between the bottom cover and the inner wall of the water tank and prevent leakage, a sealing ring is usually installed between the bottom cover and the inner wall of the water tank, and the interference fit between the sealing ring and the inner wall of the water tank is appropriately increased. However, while this design effectively improves the sealing effect, it also requires users to apply considerable force when installing or removing the bottom cover, affecting the convenience and comfort of use. Utility Model Content

[0004] The purpose of this disclosure is to provide an oral care device, oral care equipment, and grip housing that can facilitate the removal and installation of the sealing cap while ensuring a good seal, thereby improving the user experience.

[0005] According to one aspect of this disclosure, an oral care device is provided, the oral care device comprising a gripping housing and a pump assembly, wherein the gripping housing comprises: a main housing having a receiving cavity for accommodating the pump assembly and a reservoir cavity communicating with a liquid inlet end of the pump assembly, the reservoir cavity having an opening, and the main housing having a first sealing surface surrounding the periphery of the opening; a sealing cap having a base portion and an insertion portion disposed on the base portion, the base portion having a second sealing surface opposite to the first sealing surface, and the second sealing surface surrounding the insertion portion, the insertion portion being at least partially inserted into the reservoir cavity through the opening, and a sealing element being held between the first sealing surface and the second sealing surface, and the sealing element surrounding the insertion portion.

[0006] The solution provided in this disclosure involves a first sealing surface surrounding the opening of the main housing, and a second sealing surface opposite to the first sealing surface on the base portion, with the sealing element sandwiched between the first and second sealing surfaces. Thus, when the sealing cap is connected to the main housing, the sealing element is pressed between the first and second sealing surfaces without needing to be inserted into the liquid storage cavity. This avoids the need for a large force due to the large interference fit between the sealing element and the liquid storage cavity when inserting the sealing cap, facilitating installation and improving the user experience. Furthermore, it eliminates the need to reduce the interference fit of the sealing element due to installation difficulties, ensuring a reliable seal.

[0007] Furthermore, when the sealing cap is removed from the main housing, there is no force between the sealing element and the inner wall of the main housing, and the restoring force of the sealing element returning to its initial state can also squeeze at least part of the sealing cap out of the liquid storage cavity, assisting in disassembly, facilitating disassembly operations, and improving the user experience.

[0008] According to another aspect of this disclosure, an oral care device is also provided, the oral care device comprising an oral care element and the oral care apparatus described above, the oral care element having a cavity and an outlet communicating with the cavity, and the outlet end of the pump assembly communicating with the cavity.

[0009] According to another aspect of this disclosure, a grip housing is also provided, the grip housing comprising:

[0010] The main housing has a receiving cavity for accommodating the pump assembly and a liquid storage cavity communicating with the liquid inlet end of the pump assembly, the liquid storage cavity having an opening and a first sealing surface surrounding the periphery of the opening;

[0011] A sealing cap has a base portion and an insertion portion disposed on the base portion. The base portion has a second sealing surface facing the main housing and the second sealing surface is disposed around the insertion portion. The insertion portion is at least partially inserted into the liquid storage cavity through the opening. A sealing element is held between the first sealing surface and the second sealing surface and the sealing element is disposed around the insertion portion. Attached Figure Description

[0031] A water flosser uses a pump to deliver a high-pressure jet of water, which is then used to clean teeth and between teeth. Water flossers can have an integrated water tank for easy portability. They can also be used with a cleaning station, where the station's internal water tank provides the rinsing water flow. In water flossers with an integrated water tank, scale, bacteria, or impurities can easily accumulate in the tank after prolonged use (especially with tap water). To facilitate cleaning, a removable bottom cover is usually designed at the bottom of the water flosser, allowing users to easily open the cover for thorough cleaning of the tank's inner surface.

[0032] Considering that liquid inside the water tank may leak out through the gap between the bottom cover and the inner wall of the tank, a sealing ring is usually installed between the bottom cover and the inner wall of the tank, and the interference fit between the sealing ring and the inner wall of the tank is appropriately increased to ensure the seal between the bottom cover and the inner wall of the tank and prevent water leakage. However, while this design effectively improves the sealing effect, it also requires users to apply considerable force when removing and installing the bottom cover, affecting the convenience and comfort of use. Therefore, this disclosure attempted to reduce the interference fit between the sealing ring and the inner wall of the tank to facilitate the removal and installation of the bottom cover. However, this method leads to a decrease in the sealing effect, resulting in water leakage.

[0033] Based on this, this disclosure redesigns the sealing method between the bottom cover and the water tank opening. Specifically, a sealing surface facing the water tank structure is reserved on the bottom cover, and a sealing element is set on the sealing surface, surrounding the water tank opening. In this way, when the bottom cover is connected to the water tank structure, the sealing element is not inserted into the water tank, but is pressed against it by the sealing surface. This avoids the need for a large force due to a large interference fit between the sealing element and the inner wall of the water tank when the bottom cover is inserted, facilitating installation and improving the user experience. Simultaneously, it eliminates the need to reduce the interference fit of the sealing element due to installation difficulties, ensuring a good seal. When disassembling the bottom cover from the water tank structure, there is no force between the sealing element and the inner wall of the water tank, and the restoring force of the sealing element returning to its initial state can also push the bottom cover out of the water tank structure, assisting in disassembly and improving the user experience.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this disclosure, but not all embodiments.

[0035] like Figure 1As shown, this disclosure provides an oral care device. The oral care device may include an oral care apparatus 1000 and an oral care element 2000. The oral care apparatus 1000 may be configured in a shape suitable for holding, so that a user can operate the oral care device to perform cleaning operations by holding the oral care apparatus 1000. The oral care apparatus 1000 may provide at least a flow of water to the oral care element 2000 to perform water jet impact through the oral care element 2000, thereby rinsing and cleaning the oral cavity.

[0036] Regarding the specific structure of the oral care device 1000, as follows: Figures 1 to 5 As shown, in some embodiments, the oral care device 1000 may include a grip housing 100 and a pump assembly 200. The grip housing 100 may include a main housing 110, which serves as the primary support structure for the oral care device 1000. It not only supports and protects other components of the oral care device 1000 but can also be configured to a shape suitable for gripping, facilitating handling. Specifically, the main housing 110 may have a receiving cavity 112 and a liquid storage cavity 113. The receiving cavity 112 and the liquid storage cavity 113 are isolated from each other, forming a dry-wet separation design to prevent liquid in the liquid storage cavity 113 from seeping into the receiving cavity 112 and damaging the electronic components within the receiving cavity 112. The pump assembly 200 may be disposed within the receiving cavity 112, and the inlet end of the pump assembly 200 is connected to the liquid storage cavity 113 to draw liquid from the liquid storage cavity 113. The liquid storage cavity 113 has an opening 1131, through which the interior of the liquid storage cavity 113 can be cleaned or liquid can be introduced into the liquid storage cavity 113. For example, the opening 1131 may be located as follows: Figure 2 The bottom surface of the main housing 110 is shown from a certain perspective; of course, the opening 1131 can also be located on the side or top surface of the main housing 110. Considering that the bottom surface of the main housing 110 can be provided with a large opening area, and the inner wall surface of the liquid storage cavity 113 can be cleaned in a straight direction, it is preferable that the opening 1131 is located on the bottom surface of the main housing 110.

[0037] The gripping housing 100 may also include a sealing cap 120, which is used to seal the opening 1131 to prevent liquid in the liquid storage chamber 113 from leaking out through the opening 1131. Specifically, the sealing cap 120 has an insertion portion 121 and a base portion 122, with the insertion portion 121 disposed on the base portion 122. The main housing 110 is provided with a first sealing surface 1132 surrounding the opening 1131, and the base portion 122 has a second sealing surface 1221 opposite to the first sealing surface 1132, and the second sealing surface 1221 is disposed around the insertion portion 121, with the second sealing surface 1221 located between the outer wall surface of the insertion portion 121 and the outer wall surface of the base portion 122. The insertion part 121 is at least partially inserted into the liquid storage cavity 113 through the opening 1131. The sealing element 130 is held between the first sealing surface 1132 and the second sealing surface 1221, and the sealing element 130 is arranged around the insertion part 121, thereby reducing the assembly gap between the sealing cover 120 and the main housing 110.

[0038] For example, the direction in which the insertion part 121 is inserted into the liquid storage cavity 113 is defined as the insertion direction, and the first sealing surface 1132 and the second sealing surface 1221 may be approximately perpendicular to the insertion direction. During the process of the sealing cap 120 being at least partially inserted into the liquid storage cavity 113 through the insertion part 121 and the opening 1131, the insertion part 121 may not contact the inner wall surface of the liquid storage cavity 113, that is, the interference between the insertion part 121 and the inner wall surface of the liquid storage cavity 113 is 0; of course, the insertion part 121 may also contact the inner wall surface of the liquid storage cavity 113.

[0039] It is worth mentioning that this disclosure features a first sealing surface 1132 surrounding the opening 1131 on the main housing 110, and a second sealing surface 1221 opposite to the first sealing surface 1132 on the base portion 122. The sealing element 130 is held between the first sealing surface 1132 and the second sealing surface 1221. In this way, when the sealing cover 120 is connected to the main housing 110, the sealing element 130 is pressed between the first sealing surface 1132 and the second sealing surface 1221 without needing to be inserted into the liquid storage cavity 113. This avoids the need for a large force when the sealing element 130 is inserted into the liquid storage cavity 113 due to the large interference fit between the sealing element 130 and the liquid storage cavity 113. This facilitates installation and improves the user experience. At the same time, it eliminates the need to reduce the interference fit of the sealing element 130 due to inconvenient installation, ensuring a good sealing effect.

[0040] Furthermore, when the sealing cap 120 is removed from the main housing 110, there is no force between the sealing element 130 and the inner wall of the main housing 110, and the restoring force of the sealing element 130 returning to its initial state can also squeeze at least a portion of the sealing cap 120 out of the liquid storage cavity 113, assisting in disassembly, facilitating disassembly operations, and improving the user experience.

[0041] In some embodiments, such as Figure 4 As shown, the sealing cap 120 can be generally constructed as a barrel-shaped structure. The sealing cap 120 surrounds a liquid storage tank that communicates with the liquid storage cavity 113, thereby increasing the liquid storage capacity of the oral care device 1000 and extending the cleaning time of the oral care device. The cross-section of the insertion part 121 narrows from the base part 122 toward the main housing 110, thereby reducing the head size of the insertion part 121 and making it easier to insert the insertion part 121 into the opening 1131.

[0042] In some embodiments, the sealing element 130 may be disposed on the first sealing surface 1132, or the sealing element 130 may be disposed on the main housing 110.

[0043] In some other embodiments, the sealing element 130 may be disposed on the second sealing surface 1221, or the sealing element 130 may be disposed on the sealing cover 120 and installed together with the sealing cover 120 on the main housing 110.

[0044] In this embodiment, the sealing element 130 can also be sleeved on the outer wall surface of the insertion portion 121, thereby radially limiting the sealing element 130 by the insertion portion 121, preventing the sealing element 130 from radially moving and ensuring the sealing effect. For example, the sealing element 130 may have a certain degree of elasticity. When the sealing element 130 is not under force, the inner ring size of the sealing element 130 may be slightly smaller than the size of the insertion portion 121, so that the sealing element 130 can generate a certain elastic force to be sleeved and fixed on the outer wall surface of the insertion portion 121, further preventing the sealing element 130 from radially moving.

[0045] In some embodiments, the sealing element 130 may be a sealing ring or a lip seal, etc.

[0046] In some other embodiments, such as Figures 4 to 6 As shown, the sealing element 130 may include a mounting portion 131 and a sealing portion 132. The mounting portion 131 is sleeved on the insertion portion 121 and supported on the second sealing surface 1221. The sealing portion 132 extends from the mounting portion 131 toward the first sealing surface 1132, thereby forming a seal by the sealing portion 132 pressing against the first sealing surface 1132.

[0047] For example, the mounting portion 131 can be constructed as an annular ring structure with a cross-sectional width slightly greater than its thickness to increase the contact area between the mounting portion 131 and the second sealing surface 1221, thereby ensuring installation stability. The mounting portion 131 and the sealing portion 132 can be an integral structure, and the mounting portion 131 and the sealing portion 132 can be made of materials with certain elastic properties, such as rubber or silicone.

[0048] Furthermore, the sealing portion 132 can be connected to one end of the mounting portion 131 adjacent to the insertion portion 121, and the sealing portion 132 extends towards the first sealing surface 1132 while also extending towards the end of the mounting portion 131 away from the insertion portion 121. In other words, in Figure 2 From the shown perspective, the sealing portion 132 is inclined outward and upward from the mounting portion 131; alternatively, the sealing portion 132 is connected to the end of the mounting portion 131 away from the insertion portion 121, and the sealing portion 132 extends towards the first sealing surface 1132 while also extending towards the end of the mounting portion 131 adjacent to the insertion portion 121. Furthermore, a predetermined angle α exists between the sealing portion 132 and the mounting portion 131. In this way, the free end of the sealing portion 132 has a relatively long length. When the sealing portion 132 is clamped between the first sealing surface 1132 and the second sealing surface 1221, the sealing portion 132 can undergo elastic deformation due to its longer length, increasing the contact area between the sealing portion 132 and the first sealing surface 1132, thereby improving the sealing effect.

[0049] Furthermore, the preset included angle α is in the range of [15°, 65°], so that the sealing part 132 has sufficient pressure on the first sealing surface 1132, and at the same time, it can produce a certain deformation to increase the contact area, thereby improving the sealing effect. Preferably, the preset included angle α is in the range of [40°, 45°].

[0050] When the sealing cover 120 is installed on the main housing 110, the sealing element 130 is not exposed on the outer surface of the whole formed by the sealing cover 120 and the main housing 110, or in other words, the sealing element 130 can be hidden inside the outer surface of the whole formed by the sealing cover 120 and the main housing 110.

[0051] Specifically, such as Figures 1 to 3 As shown, in some embodiments, the main housing 110 is further surrounded by a mating surface 1133 around the opening 1131, and a first sealing surface 1132 is located between the opening 1131 and the mating surface 1133. The mating surface 1133 is disposed adjacent to the second sealing surface 1221 relative to the first sealing surface 1132. In other words, in Figure 2 From the shown perspective, the mating surface 1133 is located below the first sealing surface 1132. Thus, when the sealing cap 120 is connected to the main housing 110, the mating surface 1133 abuts against the second sealing surface 1221, causing the outer walls of the main housing 110 and the sealing cap 120 to substantially contact each other, forming a complete surface. The sealing element 130 is sandwiched between the first sealing surface 1132 and the second sealing surface 1221 without leakage, thereby ensuring the integrity of the overall outer surface formed by the sealing cap 120 and the main housing 110, reducing the step difference on the outer surface of the oral care device 1000, and improving the overall aesthetics. For example, the first sealing surface 1132 and the mating surface 1133 are substantially parallel and stepped.

[0052] In this embodiment, as Figure 2 As shown, the second sealing surface 1221 can be in contact with the outer wall surface of the insertion part 121 and the outer wall surface of the base part 122.

[0053] Of course, when the main housing 110 is surrounded by a mating surface 1133 around the opening 1131, and the first sealing surface 1132 is located between the opening 1131 and the mating surface 1133, the second sealing surface 1221 can also be in contact with the outer wall surface of the base portion 122 through the second mating surface. The second sealing surface 1221 and the second mating surface are not coplanar. When the sealing cover 120 is connected to the main housing 110, the mating surface 1133 abuts against the second mating surface, so that the outer wall surface of the main housing 110 and the sealing cover 120 are approximately in contact to form a complete surface.

[0054] When the sealing cap 120 is installed on the main housing 110, the sealing element 130 can be exposed on the outer surface of the whole formed by the sealing cap 120 and the main housing 110, or in other words, the sealing element 130 forms part of the outer surface of the grip housing 100.

[0055] Specifically, such as Figures 7 to 9 As shown, the first sealing surface 1132 is in contact with the inner and outer wall surfaces of the main housing 110. Thus, when the sealing cover 120 is connected to the main housing 110, the first sealing surface 1132 and the second sealing surface 1221 clamp the sealing element 130, and the first sealing surface 1132 and the second sealing surface 1221 do not contact each other, thereby exposing the sealing element 130.

[0056] In this embodiment, the second sealing surface 1221 can be in contact with the outer wall surface of the insertion part 121 and the outer wall surface of the base part 122.

[0057] In practical applications, the sealing cap 120 can be installed on the main housing 110 by utilizing the friction between the insertion part 121 and the inner wall surface of the liquid storage cavity 113.

[0058] To prevent the sealing cap 120 from accidentally falling off, the sealing cap 120 can also be secured to the main housing 110 using a snap-fit ​​structure. Specifically, as shown... Figure 10 As shown, the inner wall of the liquid storage cavity 113 is provided with a fastening groove 114, and the sealing cover 120 is provided with a fastening part 123 that cooperates with the fastening groove 114. The sealing cover 120 is connected to the main housing 110 through the fastening part 123 cooperating with the fastening groove 114, and the fastening force of the fastening part 123 and the fastening groove 114 is used to clamp the sealing element 130 between the first sealing surface 1132 and the second sealing surface 1221, ensuring the stability of the sealing of the gap between the first sealing surface 1132 and the second sealing surface 1221 by the sealing element 130, and improving the clamping force on the sealing element 130, ensuring the fit between the sealing element 130 and the first sealing surface 1132 and the second sealing surface 1221, and improving the sealing effect.

[0059] For example, the engaging portion 123 may be located on the insertion portion 121 and at least partially protrude from the outer wall surface of the insertion portion 121. The engaging portion 123 may be located at the end of the sealing element 130 away from the base portion 122. The engaging portion 123 may be a fixed structure, whereby the engaging portion 123 enters the engaging groove 114 and engages with it through the elastic deformation of the base portion 122, the main housing 110, or the engaging portion 123. The engaging portion 123 may also be configured as an adjustable structure, whereby an elastic button is provided. Pressing the elastic button causes the engaging portion 123 to retract from the engaging groove 114, and when not pressed, the engaging portion 123 resets under the action of elastic force.

[0060] Of course, the fastening part 123 can also be located on the inner wall surface of the liquid storage cavity 113, and correspondingly, the fastening groove 114 is located on the sealing cover 120.

[0061] The inlet end of the pump assembly 200 can be directly connected to the liquid storage chamber 113.

[0062] The inlet end of the aforementioned pump assembly 200 can also be connected to the liquid storage chamber 113 via the extraction pipe 300. Specifically, as shown... Figure 1 As shown, in some embodiments, the oral care device 1000 may further include a pull-out tube 300, one end of which is located within the liquid storage chamber 113 and connected to a connector 310, and the other end of which is connected to the liquid inlet of the pump assembly 200. Thus, after removing the sealing cap 120, it can be directly connected to an external water source or a base station with a water tank via the connector 310, enabling flexible switching between integrated and external water source modes to meet different usage needs.

[0063] For example, in Figure 1 From the perspective shown, one end of the extraction tube 300 can extend as far as possible to the bottom of the liquid storage cavity 113, thereby allowing liquid to be extracted from the bottom of the liquid storage cavity 113 through the extraction tube 300. It should be noted that a certain gap should be maintained between the extraction tube 300 and the inner bottom surface of the liquid storage cavity 113 so that liquid in the liquid storage cavity 113 can enter the extraction tube 300 through this gap.

[0064] In some embodiments, such as Figure 1 As shown, the oral care device described above can be configured as a water flosser to clean teeth and interdental spaces using the impact force of a high-speed water jet. Accordingly, the oral care element 2000 can be constructed as a nozzle having a cavity and an outlet connected to the cavity. The outlet end of the pump assembly 200 is connected to the cavity, thereby drawing liquid from the pump assembly 200 and delivering the liquid to the cavity, which then flows out from the outlet to perform water jet impact.

[0065] In some other embodiments, such as Figure 11 As shown, the oral care device described above can also be configured as a combined water rinsing and brushing unit, which integrates the high-frequency vibration of an electric toothbrush with the pulsed water flow of a water flosser. Correspondingly, the oral care element 2000 can be constructed as a brush head, having bristles, a cavity, and an outlet communicating with the cavity, the outlet opening towards the bristles. The oral care device 1000 may also include a drive assembly 400 with an output shaft, the output shaft being connected to and driving the oral care element 2000 to perform displacement movement, and the outlet end of the pump assembly 200 communicating with the cavity through the flow channel of the output shaft, the pump assembly 200 outputting a water flow impact through the outlet.

[0066] It should be noted that the drive assembly 400 can be a motor, the output shaft is the motor shaft, the output shaft extends to the opposite ends of the drive assembly 400 along the axial direction, and the flow path of the output shaft passes through the opposite ends of the output shaft along the axial direction.

[0067] According to another aspect of this disclosure, a grip housing 100 is also provided. The grip housing 100 includes:

[0068] The main housing 110 has a accommodating cavity 112 for accommodating the pump assembly 200 and a liquid storage cavity 113 communicating with the liquid inlet end of the pump assembly 200. The liquid storage cavity 113 has an opening 1131 and a first sealing surface 1132 is provided around the periphery of the opening 1131.

[0069] The sealing cap 120 has a base portion 122 and an insertion portion 121 provided on the base portion 122. The base portion 122 has a second sealing surface 1221 facing the main housing 110 and the second sealing surface 1221 is disposed around the insertion portion 121. The insertion portion 121 is at least partially inserted into the liquid storage cavity 113 through the opening 1131. A sealing element 130 is held between the first sealing surface 1132 and the second sealing surface 1221 and the sealing element 130 is disposed around the insertion portion 121.

[0070] It should be noted that the specific structure of the gripping housing 100 can be found in the detailed description in the above embodiments, and will not be repeated here.

[0071] The terms "upper" and "lower" used in this disclosure are used to describe the relative positional relationship of the various structures in the accompanying drawings. They are only for the purpose of clarity of description and are not intended to limit the scope of implementation of this disclosure. Changes or adjustments to the relative relationships without substantially altering the technical content should also be considered as part of the scope of implementation of this disclosure.

[0072] It should be noted that, in this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium.
