Description

Technical Field

[0001] This utility model relates to the field of rinsing technology, and in particular to a rinsing device and a rinsing apparatus including the rinsing device. Background Technology

[0002] Irrigation devices have a wide range of applications in many fields, including personal care, bathroom cleaning, medical and health care, and item cleaning.

[0003] However, existing flushers generally suffer from complex structural designs, difficulty in balancing flushing power, flushing distance, and flushing area, low fault tolerance, and short service life. For example, existing direct-flow flushers often suffer from concentrated flushing water flow, excessive flushing power, and limited flushing area; while existing nozzle-type flushers can expand the flushing area, they struggle to balance flushing power and flushing distance, and increasing the flushing distance significantly reduces flushing power, thus affecting the flushing effect. Utility Model Content

The flusher includes a main structure having a main channel to allow fluid medium to pass through, and a flow guiding structure located within the main channel and having a flow guiding hole communicating with the main channel; wherein, the flow guiding structure is adapted to vibrate when the fluid medium flows through the flow guiding hole, so that the fluid medium leaves the flusher in the form of a scattered flow. This invention, by setting a flow guiding structure that can vibrate when the fluid medium passes through the main channel of the flusher, and then using the vibration of the flow guiding structure to make the fluid medium spray out in the form of a scattered flow, not only has a simple structural design, but also takes into account flushing force, flushing distance, and flushing area, while also improving the fault tolerance and service life of the flusher.

[0005] Therefore, the present invention provides the following technical solution:

[0006] One aspect of this invention is to provide a flushing device. The flushing device includes a main body structure and a flow guiding structure; the main body structure has a main channel to allow fluid medium to pass through; the flow guiding structure is located within the main channel and has a flow guiding hole communicating with the main channel; the flow guiding structure is adapted to vibrate when the fluid medium flows through the flow guiding hole, causing the fluid medium to leave the flushing device in the form of a scattered flow.

[0007] Optionally, the flow guiding structure further includes a vibrating part having the flow guiding hole; the vibrating part is adapted to vibrate when the fluid medium flows through the flow guiding hole.

[0008] Optionally, the vibrating part further includes slits spaced around the periphery of the guide hole; the slits are adapted to open to expand the guide hole when the vibrating part is impacted by a fluid medium, and to close to contract the guide hole when the impact disappears.

[0009] Optionally, the vibrating part is adapted to drive the guide hole to vibrate reciprocally, so that the periphery of the guide hole presents a petal-like structure that changes reciprocally.

[0010] Optionally, the flusher further includes a diffusion channel located within the main channel; the diffusion channel communicates with the guide hole to receive and allow the scattered flow to exit the flusher; the peripheral edge of the guide hole is also adapted to move toward the diffusion channel and be at least partially located within the diffusion channel.

[0011] Optionally, the flusher further includes a diffusion channel located within the main channel; the diffusion channel communicates with the guide hole to receive and allow the scattered flow to exit the flusher; a gap exists between the diffusion channel and the vibrating part to provide vibration space for the vibrating part.

[0012] Optionally, the flow guiding structure further includes a wall extending from the vibrating part; the wall is adapted to bend in the direction of the diffusion channel and together with the vibrating part and the diffusion channel define the gap.

[0013] Optionally, the flushing device further includes a diffusion structure located within the main channel and adapted to define the diffusion channel; the diffusion structure has a boss extending toward the vibrating part; the curved portion of the wall is adapted to be embedded between the boss and the main channel, thereby sealing the diffusion structure and the main channel.

[0014] Optionally, the flow guiding structure further includes a wall extending from the vibrating part; the wall is adapted to bend in the direction of fluid medium departure; the main channel has a groove corresponding to the wall; the wall is fitted into the groove to seal the flow guiding structure and the main channel.

[0015] Optionally, the wall is adapted to vibrate under the influence of the vibrating part.

[0016] Another aspect of this invention is to provide a rinsing device. This rinsing device includes the rinsing device provided by this invention.

[0017] Compared with the prior art, the technical solution provided by this utility model has at least the following beneficial effects.

[0018] For example, this utility model sets up a flow guide structure in the main channel of the flusher that can vibrate when the fluid medium passes through, and the fluid medium is sprayed out in the form of a scattering flow through the vibration of the flow guide structure. Not only is the structural design simple, but it can also take into account the flushing force, flushing distance and flushing area, and at the same time improve the fault tolerance and service life of the flusher.

[0019] For example, during the continuous impact of the fluid medium on the vibrating part, the periphery of the guide hole of this utility model will exhibit a petal-like structure to better scatter the fluid medium.

[0020] For example, the vibrating part of the flushing device of this invention may also include gaps spaced around the periphery of the guide hole. These gaps open when the vibrating part is impacted by the fluid medium, thereby expanding the guide hole and enhancing the scattering effect and scattering area of ​​the fluid medium.

[0021] For example, the gaps also make the petal-like structure around the periphery of the flow guide hole more prominent, which can enhance the "blooming" of the petal-like structure and thus better scatter the fluid medium.

[0022] For example, compared to a direct-flow flushing device, the flushing device provided by this invention sprays fluid in the form of a diffused flow, which can effectively increase the flushing area.

[0023] For example, compared to nozzle-type flushers, the flusher provided by this utility model can not only increase the flushing distance while taking into account the flushing force, but also avoid the problems of low fault tolerance and short service life caused by the presence of nozzles.

[0024] The low fault tolerance of nozzle-type flushers refers to their high requirements for the purity of the fluid medium. Because the nozzle has a certain length in the direction of fluid medium movement, even small impurities in the fluid medium can cause significant friction and damage to the nozzle. However, the flusher provided by this invention has a shorter guide structure in the direction of fluid medium movement, preventing damage to the guide structure due to small impurities in the fluid medium.

[0025] For example, compared to nozzle-type flushers, the flusher provided by this utility model can concentrate the flushing area, thereby increasing the flushing force per unit area. At the same time, it is less affected by air resistance, and can also achieve a more efficient and painless flushing effect over a longer distance. In addition, it can also reduce the power and energy consumption of the fluid medium delivery unit.

[0026] For example, the rinsing device provided by this utility model has broad application prospects. For instance, this rinsing device is suitable for rinsing teeth, and when rinsing teeth, it not only reduces the impact force to protect the gums through the scattering flow, but also increases the rinsing area to improve rinsing efficiency through the scattering flow. For another example, this rinsing device is also suitable for body cleaning, and can achieve strong rinsing power and effect without needing to be close to the body parts. Of course, this rinsing device can also be applied to many other fields such as personal care, bathroom cleaning, medical hygiene, and item cleaning; this utility model does not limit its applications.

[0040] To make the objectives, features, and beneficial effects of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It is to be understood that the specific embodiments described below are merely for explaining this utility model and are not intended to limit it. Furthermore, descriptions of identical or similar components in different embodiments, as well as descriptions of components, features, effects, etc., belonging to the prior art, may be omitted.

[0041] Furthermore, for ease of description, the accompanying drawings may show only the parts relevant to this invention, rather than the entire structure. Also, the same or similar reference numerals may be used in the drawings to refer to the same or similar components in different embodiments.

[0042] Reference Figures 1 to 8 This utility model embodiment provides a flushing device 10.

[0043] Specifically, the flushing device 10 includes a main structure 110 and a flow guiding structure 120. The main structure 110 has a main channel 111 to allow fluid medium to pass through; the flow guiding structure 120 is located within the main channel 111 and has a flow guiding hole 121 communicating with the main channel 111.

[0044] In a specific implementation, the flow guiding structure 120 is adapted to vibrate when the fluid medium flows through the flow guiding hole 121, so that the fluid medium leaves the flusher 10 in the form of a scattered flow.

[0045] By adopting the above technical solution, by providing a flow guide structure 120 that can vibrate when the fluid medium passes through the main channel 111 of the flusher 10, the flusher 10 can be adapted to spray the fluid medium in the form of a scattering flow.

[0046] In some embodiments, the fluid medium may include a liquid medium, such as water, cleaning fluid, etc.

[0047] In a specific implementation, the main channel 111 of the flusher 10 extends along the direction in which the fluid medium passes, and has an inlet and an outlet located at both ends of the main channel 111 to receive the fluid medium and allow the fluid medium to leave the flusher 10.

[0048] In some embodiments, the flusher 10 is adapted to be connected to a fluid medium delivery unit and to receive fluid medium through the fluid medium delivery unit.

[0049] In a specific implementation, the fluid medium delivery unit is adapted to be connected to the inlet of the main channel 111 of the flusher 10 so as to deliver the fluid medium to the main channel 111 of the flusher 10 through the inlet.

[0050] In some embodiments, the fluid medium delivery unit may include a fluid medium pump. The fluid medium pump is adapted to be connected to a fluid medium source to pump fluid medium from the fluid medium source to the main channel 111 of the flusher 10.

[0051] For example, the fluid medium delivery unit may be a water pump connected to a water source to pump water from the water source to the main channel 111 of the flusher 10.

[0052] It is understood that the fluid medium transport unit may also take any other form known in the prior art, and no limitation is made here.

[0053] In other embodiments, the flusher 10 may also include a fluid medium delivery unit, through which fluid medium is delivered to the main channel 111.

[0054] In some embodiments, the flushing device 10 may further include a handle structure 140 connected to the main body structure 110 for easy gripping of the flushing device 10. In a specific implementation, a fluid medium delivery unit may be disposed within the handle structure 140.

[0055] In some embodiments, the handle structure 140 also has a fluid channel communicating with the main channel 111 to receive fluid medium from the outside, thereby allowing the fluid medium to be transported into the main channel 111 under the action of the fluid medium transport unit.

[0056] In a specific implementation, the flow guiding structure 120 is disposed in the main channel 111 and has a flow guiding hole 121, so that the fluid medium is suitable to leave through the flow guiding hole 121 after entering the main channel 111.

[0057] In specific implementations, the guide hole 121 can be a regular or irregular shape such as a circle, triangle, polygon, or straight line, and no limitation is made here.

[0058] In a specific implementation, the flow guiding structure 120 further includes a vibrating part 122 having a flow guiding hole 121. The vibrating part 122 is at a certain angle to the flow direction of the fluid medium so that the fluid medium is suitable for passing through the flow guiding hole 121. The vibrating part 122 is also adapted to vibrate when the fluid medium flows through the flow guiding hole 121, thereby forming a scattered flow of the fluid medium.

[0059] In some embodiments, the vibrating part 122 is adapted to be made of an elastic material, such as an elastic film.

[0060] In a specific implementation, the vibrating part 122 is adapted to drive the guide hole 121 to vibrate under the external excitation, i.e., the impact of the fluid medium. This causes the resistance encountered by the fluid medium when passing through the guide hole 121 to be uneven, resulting in different flow velocity distributions of the fluid medium in the central and edge regions of the guide hole 121. That is, the flow velocity in the central region of the guide hole 121 is lower, and the flow velocity in the edge region of the guide hole 121 is higher. This difference in flow velocity distribution will cause the fluid medium to have different flow directions when leaving the guide hole 121, thus achieving the scattering effect of the fluid medium.

[0061] Furthermore, since the force of the fluid medium impacting the vibrating part 122 is not completely uniform, the impact force on the peripheral edge 123 of the guide hole 121 is not the same during the continuous impact of the fluid medium on the vibrating part 122. In this case, the peripheral edge 123 of the guide hole 121 will exhibit a petal-like structure 124. In this way, the fluid medium can be better scattered.

[0062] It is understandable that the peripheral edge 123 of the guide hole 121 is included in the vibrating part 122.

[0063] In specific implementations, the vibrating part 122 is also adapted to reciprocate under external excitation, i.e., the impact of the fluid medium, causing the guide hole 121 to reciprocate as well, and simultaneously causing the effective area of ​​the guide hole 121 to reciprocate accordingly. This causes the petal-like structure 124 of the peripheral edge 123 of the guide hole 121 to reciprocate, meaning the "degree of blooming" of the petal-like structure 124 also reciprocates. Furthermore, it is understood that when the fluid medium stops impacting the vibrating part 122, the guide hole 121 also stops vibrating, causing its peripheral edge 123 to close and restore the initial shape of the guide hole 121.

[0064] In some embodiments, the fluid medium is adapted to enter the main channel 111 of the flusher 10 in a straight flow. The vibrating part 122 is adapted to vibrate as the straight flow passes through the guide hole 121, thereby converting the straight flow into a scattered flow.

[0065] In other embodiments, the fluid medium may also enter the main channel 111 of the flusher 10 in other forms and is adapted to cause the vibrating part 122 to vibrate as it passes through the guide hole 121 and form a scattered flow under the action of the vibration.

[0066] It is understood that the fluid medium can also enter the main channel 111 of the flusher 10 in the form of a scattered flow, and is adapted to cause the vibrating part 122 to vibrate when passing through the guide hole 121 and enhance the scattering effect under the action of the vibration.

[0067] In some embodiments, the vibration direction of the vibrating part 122 is parallel to the direction of the fluid medium passing through the guide hole 121, which can enhance the scattering effect of the fluid medium.

[0068] In some embodiments, when the fluid medium flows through the guide hole 121, the flow velocity will increase due to the reduction in the radial dimension of the flow channel, thereby increasing the impact force of the fluid medium.

[0069] In some embodiments, the vibrating part 122 may further include slits 125 spaced apart around the peripheral edge 123 of the flow guide hole 121. The slits 125 are adapted to open when the vibrating part 122 is impacted by a fluid medium to expand the flow guide hole 121, and to close when the impact disappears to contract the flow guide hole 121. For example, Figure 6 and Figure 7 As shown.

[0070] As mentioned above, since the guide hole 121 vibrates back and forth under the drive of the vibrating part 122, the petal-like structure 124 of the peripheral edge 123 of the guide hole 121 also changes back and forth. When the vibrating part 122 has gaps 125 spaced around the peripheral edge 123 of the guide hole 121, the gaps 125 will make the petal-like structure 124 more prominent, that is, it can improve the "blooming degree" of the petal-like structure 124, thereby better scattering the fluid medium.

[0071] In some embodiments, the slits 125 extend radially along the guide hole 121 and are arranged in a plurality of uniformly arranged around the periphery of the guide hole 121. This can better enhance the scattering effect of the fluid medium.

[0072] In some embodiments, the flusher 10 further includes a diffusion channel 131 located within the main channel 111. The diffusion channel 131 communicates with the guide hole 121 to receive and allow the scattered flow to exit the flusher 10.

[0073] In some embodiments, the radial dimension of the diffusion channel 131 gradually increases in the direction of fluid medium exit to better receive and allow the scattered flow to exit the flusher 10.

[0074] In some embodiments, the peripheral edge 123 of the guide hole 121 is also adapted to move toward the diffusion channel 131 during reciprocating changes and to be at least partially located within the diffusion channel 131. In this way, space can be utilized effectively.

[0075] In some embodiments, the at least partially included peripheral edge 123 of the flow guide 121 presents a petal-like structure 124.

[0076] In some embodiments, a gap 112 is further provided between the diffusion channel 131 and the vibration part 122 to provide vibration space for the vibration part 122.

[0077] In some embodiments, the flow guiding structure 120 further includes a wall 126 extending from the vibrating part 122. The wall 126 is adapted to bend toward the direction of the diffusion channel 131 and together with the vibrating part 122 and the diffusion channel 131 define a gap 112.

[0078] In some embodiments, the flushing device 10 further includes a diffusion structure 130 located within the main channel 111 and adapted to define a diffusion channel 131. The wall 126 is also adapted to define a gap 112 together with the vibrating part 122 and the diffusion structure 130.

[0079] In some embodiments, the side of the vibrating part 122 away from the gap 112 is not fixedly attached to the inner wall of the main channel 111 or is directly exposed in the main channel 111, so that the vibrating part 122 can be provided with a vibration space away from the gap 112.

[0080] In some embodiments, the diffusion structure 130 further has a boss 132 extending toward the vibrating portion 122. The curved portion of the wall 126 is adapted to be tightly embedded between the outer peripheral sidewall of the boss 132 and the inner peripheral sidewall of the main channel 111, thereby sealing the connection between the diffusion structure 130 and the main channel 111.

[0081] In some embodiments, the main channel 111 further has a groove 113 corresponding to the wall 126. The outer side of the wall 126 is also adapted to fit into the groove 113 so that the flow guide structure 120 and the main channel 111 are sealed together.

[0082] In some embodiments, the wall 126 is adapted to vibrate under the action of the vibrating part 122, thereby enhancing the scattering effect of the fluid medium.

[0083] By employing the technical solution provided in this embodiment of the present invention, a flow guiding structure 120 capable of vibrating when a fluid medium passes through is provided within the main channel 111 of the flusher 10. This not only makes the flusher 10 suitable for spraying the fluid medium in the form of a diffused flow, but also simplifies the structural design and ensures good sealing between the components. Furthermore, compared to a direct-flow flusher, the flusher 10 of this invention, by spraying fluid in the form of a diffused flow, can effectively increase the flushing area and reduce the flushing force.

[0084] Patent document CN113116573A discloses an oral cleaning structure and device that utilizes fluid-structure interaction vibration to change the spray direction. The oral cleaning structure can be viewed as a nozzle-type irrigator, and it can also scatter the fluid medium, thereby increasing the irrigating area and reducing the irrigating force. However, this oral cleaning structure cannot simultaneously balance irrigating force and irrigating distance; that is, while increasing the irrigating distance, it significantly reduces the irrigating force, thus affecting the irrigating effect.

[0085] The following tests were conducted on the irrigator 10 provided in the embodiments of this utility model and the oral cleaning structure disclosed in CN113116573A under the same conditions, measuring the scattering angle, water output time, water output volume, and impact on the unit area of ​​the force-bearing surface. Furthermore, the test methods employed all conventional techniques in the art, which will not be elaborated upon here.

[0086] To facilitate comparison of test results, the irrigator 10 provided in this embodiment of the present invention and the oral cleaning structure disclosed in CN113116573A are designed with basically the same structure and size. The difference is that CN113116573A uses a nozzle to scatter the fluid medium, while the irrigator 10 provided in this embodiment of the present invention eliminates the nozzle and adds a flow guiding structure 120 compared to the structure disclosed in CN113116573A. At the same time, the shape and inner diameter of the flow guiding hole 121 of the irrigator 10 provided in this embodiment of the present invention are approximately the same as the shape and inner diameter of the nozzle input end disclosed in CN113116573A.

[0087] Table 1 shows the scattering angles of the sprayed streams from the irrigator 10 provided in this embodiment and the oral cleaning structure disclosed in CN113116573A at their respective water outlet terminals (i.e., the positions where the fluid medium finally leaves the irrigator 10 or the oral cleaning structure). The length and curvature of the diffusion channels of the irrigator 10 provided in this embodiment and the oral cleaning structure disclosed in CN113116573A are the same, and water was used as the fluid medium in the tests.

[0088] Table 1 Scattering Angle

[0089] The flusher 10 of this utility model embodiment The curvature of the diffusion channel is -10° to 20°. The oral cleaning structure disclosed in CN113116573A The curvature of the diffusion channel is +20° to 30°.

[0090] As can be seen from Table 1, the rinsing device 10 provided in this embodiment of the present invention has a smaller scattering angle for the fluid medium compared to the oral cleaning structure disclosed in CN113116573A, which makes the resulting scattered flow relatively concentrated, thereby effectively improving the rinsing force per unit area. At the same time, due to the relatively reduced influence of air resistance, it can also achieve a more efficient and painless rinsing effect over a longer distance.

[0091] Table 2 compares the test results of the water outlet time and water volume of the irrigator 10 provided in this embodiment and the oral cleaning structure disclosed in CN113116573A at their respective water outlet terminals (i.e., the positions where the fluid medium finally leaves the irrigator 10 or the oral cleaning structure). To ensure the reliability of the test results, each test was conducted three times.

[0092] Table 2 Water Output - Water Output Time

[0093]

[0094] As can be seen from Table 2, the rinsing device 10 provided in this embodiment of the present invention and the oral cleaning structure disclosed in CN113116573A have similar water outlet time and water volume at their respective water outlet terminals. Therefore, it can be concluded that the rinsing force of the two devices at their respective water outlet terminals is also basically the same.

[0095] Table 3 shows the test results of the impact per unit area on the force-bearing surface at a certain distance (i.e., the rinsing distance) from the water outlet terminal (i.e., the position where the fluid medium finally leaves the rinsing device 10 or the oral cleaning structure disclosed in CN113116573A) of the rinsing device 10 provided in this utility model embodiment and the oral cleaning structure within a certain period of time. The force-bearing surfaces are all circular with a diameter of 10 mm. The impact per unit area is the mass of fluid medium consumed by the force-bearing surface per unit area when rinsed by the scattered flow, which can be calculated by the increase in mass per unit area of ​​the force-bearing surface.

[0096] Table 3 Impact per unit area

[0097]

[0098] As can be seen from Table 3, with the increase of rinsing distance, the impact of the oral cleaning structure disclosed in CN113116573A on the force-bearing surface per unit area is significantly reduced, while the impact of the rinsing device 10 provided in this utility model embodiment on the force-bearing surface per unit area is not significantly reduced. Therefore, it can be seen that the rinsing device 10 provided in this utility model embodiment can maintain effective rinsing force while increasing the rinsing distance, that is, it can take into account both rinsing distance and rinsing force.

[0099] Furthermore, since the flushing device 10 provided in this embodiment of the present invention can maintain effective flushing force while increasing the flushing distance, under the same flushing distance and flushing force, the flushing device 10 provided in this embodiment of the present invention can also reduce the power and energy consumption of the fluid medium conveying unit.

[0100] Since the nozzle is eliminated, the flusher 10 provided in this embodiment of the utility model can also avoid the problems of low fault tolerance and short service life caused by the presence of the nozzle.

[0101] The low fault tolerance of nozzle-type flushers refers to their high requirements for the purity of the fluid medium. Because the nozzle has a certain length in the direction of fluid medium movement, even small impurities in the fluid medium can cause significant friction and damage to the nozzle. However, the flusher 10 provided by this invention has a shorter guide structure 120 in the direction of fluid medium movement, preventing damage to the guide structure 120 due to small impurities in the fluid medium, thus improving the fault tolerance.

[0102] The tests also revealed that, under the same testing conditions, the nozzle of the oral cleaning structure disclosed in CN113116573A would break or deteriorate due to fatigue after a period of continuous use, such as 48 hours. However, the irrigator 10 provided in this embodiment of the present invention maintained its flow guiding structure 120, including the vibrating part 122, intact after the same period of continuous use. Therefore, the irrigator 10 provided in this embodiment of the present invention can effectively extend its service life.

[0103] Reference Figure 9 This utility model embodiment also provides a rinsing device 1.

[0104] Specifically, the rinsing device 1 includes a base 20 and a rinsing device 20 mounted on the base 20.

[0105] In practice, the rinsing device 1 can be applied to multiple fields such as personal care, bathroom cleaning, medical and health care, and item cleaning, and this utility model does not limit it.

[0106] It is understood that the size of the flusher 10 described in this embodiment of the present invention can be flexibly adjusted and its structure can be predictably modified to meet the needs of different application fields and products.

[0108] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
