Description

Technical Field

[0001] This invention relates to the field of physiotherapy device technology, and in particular to a multi-directional jet self-cleaning gum massage device. Background Technology

[0002] Gingival massage is an important means of preventing and adjuvant treatment of periodontal disease. Its core mechanism is to increase local blood circulation in the gingival tissue, promote epithelial keratinization, and reduce inflammation through appropriate physical stimulation. Currently, commonly used gingival massage methods in clinical practice and at home mainly include fingertip massage, toothbrush massage, and water flosser rinsing. Existing gingival massage devices mostly use a single-hole direct-jet structure, where water can only be ejected in a single direction. Because the gums in the oral cavity are arranged in an arc, with the buccal, lingual, and interdental papilla areas located on different planes, a single-hole direct-jet water flow can only cover a point area per operation, making it impossible to apply massage pressure to multiple areas of the gums simultaneously. The operator needs to repeatedly rotate the device angle, which is cumbersome and easily creates blind spots, resulting in uneven massage effects. Existing water flosser nozzles usually use a circumferential opening design, where the water flow is scattered in all directions during spraying, but half of the water flow is directed towards the non-working side (such as the center of the mouth or the opposite gum), which not only wastes fluid but may also impact areas that do not need massage, causing patient discomfort. Meanwhile, the micropore layout of existing nozzles lacks a zoned design tailored to the anatomical morphology of the gums, resulting in limited effectiveness in fine cleaning and massaging periodontal pockets or gingival sulci.

[0003] During use, when the device stops spraying, oral fluids (including saliva, blood, plaque, etc.) are easily drawn back into the internal tubing of the handle due to pressure changes, causing cross-contamination. In addition, the micropores are in a humid environment for a long time, and biofilms easily form on the inner walls. The existing structure lacks an effective self-cleaning mechanism, and conventional cleaning is insufficient to remove the deposits on the inner walls of the micropores, affecting hygiene and safety and service life. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-directional jet self-cleaning gum massage device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] This invention provides a multi-directional jet self-cleaning gum massage device, comprising:

[0007] The handle has a fluid channel inside, which includes a main flow channel and a bypass flow channel;

[0008] The connector has one end connected to the main flow channel and the bypass flow channel respectively, and the other end is provided with a first outlet and a second outlet. The first outlet is used for the fluid to flow out of the main flow channel, and the second outlet is used for the fluid to flow out of the bypass flow channel.

[0009] The massage head has one end connected to the connector and the other end closed. The sidewall is provided with a micropore array, which forms multiple micropores around the massage head. Each micropore faces a different angle and is used to spray out from the micropores on the sidewall after the fluid enters the internal cavity of the massage head to form a multi-directional scattering jet, so as to simultaneously apply fluid pressure to massage the buccal side, lingual side and interdental papilla area of ​​the gums.

[0010] The micropore array is only disposed in one half of the circumferential region of the massage head to form the working side, and the other half of the circumferential region of the massage head is a smooth surface; the micropore array is distributed along the axial direction of the massage head as at least two jet arcs, and the micropores on each jet arc are oriented at different angles.

[0011] During massage, the fluid or water source from the main channel enters the internal cavity of the massage head through the first outlet of the connector. It is then sprayed out from the micro-holes on the working side, targeting the buccal or lingual side of the gums, simultaneously massaging multiple areas. During operation, the working side is positioned towards the gums to be massaged, maintaining a distance of 1-3 mm, and moved slowly. Traditional single-hole direct spraying can only provide point coverage, requiring repeated rotation; full-circumference micro-holes waste half the water flow and may cause injury. This technical solution concentrates the micro-holes in half the circumference, with axial arcs and different orientations, achieving simultaneous coverage of the buccal, lingual, and interdental papillae in a single operation. Different spray arcs target different gingival anatomical regions. This multi-area coverage reduces operation time, resulting in high massage efficiency and strong targeting.

[0012] As a further improvement of the present invention, the micropore array includes:

[0013] The first jet arc, with its micro-holes oriented at an angle of 80° to 85° to the axis of the massage head, is used to massage the gingival margin area.

[0014] The second jet arc, with its micro-holes oriented at an angle of 85° to 95° to the axis of the massage head, is used to massage the middle section of the gums.

[0015] The third jet arc has a micro-hole diameter smaller than that of the first and second jet arcs, and the micro-hole orientation is at 95°~105° with the axis of the massage head, used to guide the fluid jet into the superficial gingival sulcus.

[0016] The gingival margin, gingival center, and gingival sulcus require water flow in different directions. The gingival margin needs to be massaged at an angle, while the gingival sulcus needs a thin stream directed towards the root. This improved plan allows for precise zonal massage, avoiding damage to the gingival sulcus or insufficient stimulation of the gingival margin caused by a single direction.

[0017] As a further improvement of the present invention, the massage head includes:

[0018] The main channel is arranged along the axial direction of the massage head, with one end connected to the first water outlet and the other end extending into the interior of the massage head;

[0019] A bypass channel is located on one side of the main channel and is independent of the main channel, with one end of it connected to the second outlet.

[0020] The inner cavity of the cone has a relatively large cross-section at the bottom, which connects the main channel and the bypass channel. The micropore array is disposed on the cavity wall of the inner cavity of the cone, so that the fluid in the inner cavity of the cone is ejected outward through the micropore array.

[0021] A plugging head is disposed on the top side of the relatively small cross-section of the inner cavity of the truncated cone, sealing the end of the inner cavity of the truncated cone. One end of the plugging head extends toward the bottom side of the inner cavity of the truncated cone and abuts against the end of the main channel. The outer circumferential surface of the plugging head is provided with a plurality of straight grooves along the axial direction. The straight grooves are distributed in an array along the circumferential direction of the plugging head. One end of each straight groove is connected to the main channel, and the other end is connected to the inner cavity of the truncated cone, so that fluid from the main channel enters the inner cavity of the truncated cone through the straight groove.

[0022] This improved design redirects the axial water flow to a radial flow into the frustum-shaped cavity, ensuring uniform distribution. The straight groove array both redirects and homogenizes the flow, while the sealing head simultaneously closes the top of the cavity, preventing water from directly entering from the ends. The uniform water flow redirection, consistent pressure distribution within the cavity, and similar flow rates at each micropore result in a compact structure that eliminates the need for additional flow-diverting components.

[0023] As a further improvement of the present invention: the cavity wall of the truncated cone is inclined, and the micropore array is formed on the inclined surface; when water is supplied through the bypass channel, the fluid is sprayed onto the inclined cavity wall of the truncated cone after passing through the bypass channel, thus impacting and cleaning the micropore array. During operation, the switching valve of the handle switches the water source to the bypass channel, and the water is sprayed towards the inclined surface of the truncated cone cavity through the bypass channel and its outlet. The high-speed water flow impacts the micropore area, generating a pressure difference and scouring inside and outside the micropores, causing the attached substances to detach, and the mixture is discharged from the micropores.

[0024] As a further improvement of the present invention: the bottom side of the inner cavity of the cone is provided with an annular groove, part of the groove opening is aligned with the micropore array, and the outlet of the bypass channel extends axially to connect with the annular groove.

[0025] In this improved design, an annular groove is provided at the bottom plane of the inner cavity of the cone. The groove opening is aligned with the micropore array in the axial direction. The outlet of the bypass channel extends axially and connects to the annular groove. During self-cleaning, water enters the annular groove from the bypass channel and then sprays out from the groove opening (towards the inclined surface) to form a water curtain or uniformly impact the micropore array.

[0026] As a further improvement of the present invention: the number of straight grooves opened on the outer periphery of the sealing head is 4-8, and each straight groove is distributed at an equal angle along the circumference. The bottom side of the straight groove is located within the inner diameter of the main channel, so that a circumferential array of water channels is formed between the main channel and the sealing head.

[0027] In this improved design, the bottom of the straight groove is located within the inner diameter of the main channel, meaning the outer diameter of the plug head is larger than the inner diameter of the main channel, while the distance between the bottom of the groove and the axis of the plug head is smaller than the inner radius of the main channel. This allows the end of the straight groove to still connect to the main channel after the main channel and the end of the plug head are in contact, forming a circumferential array of water channels, which evenly distributes the flow and reduces eddies.

[0028] As a further improvement of the present invention: the end port of the main channel is provided with a first chamfered bevel, and the end of the sealing head facing the main channel is provided with a second chamfered bevel that matches the first chamfered bevel; the sealing head is inserted from the head of the massage head, so that the second chamfered bevel abuts and is positioned against the first chamfered bevel. The beveled contact provides a self-centering function, ensuring that the sealing head is coaxial with the main channel, with high assembly accuracy, ensuring smooth water flow, and facilitating rapid assembly during mass production.

[0029] As a further improvement of the present invention, a one-way valve is provided at the end port of the main channel, allowing the fluid in the main channel to flow unidirectionally towards the inner cavity of the cone. This prevents the bypass high-pressure water from flowing back into the main channel during self-cleaning, ensuring water path isolation and avoiding cross-contamination.

[0030] As a further improvement of the present invention: the head of the massage head is also provided with a locking ring, which is sleeved on the outside of the sealing head and fixedly connected to the massage head, thereby locking the sealing head to the end of the main channel.

[0031] The locking ring in this improved design is a ring-shaped part that fits onto the head of the massage head and is fixed to the massage head body by threads, snaps, or ultrasonic welding. The inner edge of the locking ring presses against the sealing head to prevent the sealing head from moving axially backward, ensuring reliable fixation and preventing loosening.

[0032] As a further improvement of the present invention: a switching valve is provided on the handle, the switching valve having a first working position and a second working position. In the first working position, the main flow channel is connected to the water source, and in the second working position, the bypass flow channel is connected to the clean water source. The switching valve is a manual lever type, rotary type, or push-button type valve structure. The switching valve is located on the handle, controlling the water source to connect to the main flow channel or the bypass flow channel, without both channels flowing simultaneously. The operation is intuitive and the modes are clearly distinguishable. Attached Figure Description

[0042] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0043] Reference Figures 1 to 4 The following are several embodiments of a multi-directional jet self-cleaning gum massage device of the present invention.

[0044] In some embodiments, such as Figures 1 to 3 As shown, the present invention provides a multi-directional jet self-cleaning gum massage device, comprising:

[0045] The handle 100 has a fluid channel inside, which includes a main flow channel and a bypass flow channel;

[0046] The connector 200 has one end connected to the main flow channel and the bypass flow channel respectively, and the other end is provided with a first outlet 210 and a second outlet 220. The first outlet 210 is used for the fluid to flow out of the main flow channel, and the second outlet 220 is used for the fluid to flow out of the bypass flow channel.

[0047] The massage head 300 has one end connected to the connector 200 and the other end closed. The side wall is provided with a micropore array 310. The micropore array 310 forms multiple micropores around the massage head 300, and each micropore faces a different angle. After the fluid enters the internal cavity of the massage head 300, it is sprayed out from the micropores on the side wall to form a multi-directional scattering jet, so as to simultaneously apply fluid pressure to massage the buccal side, lingual side and interdental papilla area of ​​the gums.

[0048] The micropore array 310 is only disposed in one half of the circumferential region of the massage head to form the working side, and the other half of the circumferential region of the massage head 300 is a smooth surface; the micropore array 310 is distributed along the axial direction of the massage head 300 as at least two jet arcs, and the micropores on each jet arc face different angles.

[0049] In this embodiment, the handle has two independent flow channels: a main flow channel for massage water and a bypass flow channel for self-cleaning water. A connector leads the two flow channels to the first and second water outlets respectively. This embodiment does not impose any restrictions on the specific configuration of the two flow channels within the handle and connector; conventional piping design is sufficient. Furthermore, a mating gap 230 is provided between the massage head 300 and the connector 200. A partition 340 is provided between the inlet of the main channel 320 and the inlet of the bypass channel 330 of the massage head 300. The top of the partition 340 abuts against the end face of the connector 200 and separates the first water outlet 210 and the second water outlet 220. The first water outlet 210 and the main channel 320 form an independent massage water path, and the second water outlet 220 and the bypass channel 330 form an independent self-cleaning water path. The massage head is sealed to prevent direct water jet damage to the gums, while the sidewalls have micropores. The micropore array is arranged only in half of the circumference (approximately 180°), with the other half smooth to prevent water waste and accidental spraying. The micropore array has at least two spray arcs along the axis (such as the proximal arc and the distal arc), with the micropores on each spray arc facing different directions to cover different areas such as the gingival margin, gingival midline, and gingival sulcus.

[0050] In this embodiment, during massage, the main fluid or water source enters the internal cavity of the massage head through the first outlet of the connector and is sprayed out from the micro-holes on the working side, targeting the buccal or lingual side of the gums, simultaneously massaging multiple areas. During operation, the working side should be oriented towards the gums to be massaged, maintaining a distance of 1-3 mm, and moved slowly. Traditional single-hole direct spray can only provide point coverage and requires repeated rotation; full-circumference micro-holes waste half the water flow and may cause accidental injury. This embodiment concentrates the micro-holes in half the circumference, with axial arcs and different orientations, achieving simultaneous coverage of the buccal, lingual, and interdental papillae in a single operation. Different spray arcs target different gingival anatomical regions. This multi-area coverage reduces operation time, resulting in high massage efficiency and strong targeting.

[0051] In some embodiments, the micropore array includes:

[0052] The first jet arc, with its micro-holes oriented at an angle of 80° to 85° to the axis of the massage head, is used to massage the gingival margin area.

[0053] The second jet arc, with its micro-holes oriented at an angle of 85° to 95° to the axis of the massage head, is used to massage the middle section of the gums.

[0054] The third jet arc has a micro-hole diameter smaller than that of the first and second jet arcs, and the micro-hole orientation is at 95°~105° with the axis of the massage head, used to guide the fluid jet into the superficial gingival sulcus.

[0055] In this embodiment, three jet arcs are arranged axially, each with micro-orifices facing at a different angle (relative to the axis of the massage head). The first jet arc is biased upwards, impacting the gingival margin; the second jet arc is nearly vertical and lateral, impacting the mid-gingival region; and the third jet arc is biased downwards and backwards (or slightly towards the root), with a smaller aperture, used to guide a fine stream into the gingival sulcus. The gingival margin, mid-gingival region, and gingival sulcus require water flow in different directions. The gingival margin requires oblique massage, while the gingival sulcus requires a fine stream directed towards the root. This embodiment provides precise, zoned massage, avoiding damage to the gingival sulcus or insufficient stimulation of the gingival margin caused by a single direction.

[0056] In some embodiments, such as Figures 3 to 4 As shown, the massage head 300 includes:

[0057] The main channel 320 is arranged along the axial direction of the massage head 300, with one end connected to the first water outlet 210 and the other end extending into the interior of the massage head 300.

[0058] The bypass channel 330 is located on one side of the main channel 320 and is independent of the main channel 320. One end of the bypass channel 330 is connected to the second outlet 220.

[0059] The inner cavity 350 of the cone has a relatively large bottom side that connects the main channel 320 and the bypass channel 330. The micropore array 310 is disposed on the cavity wall of the inner cavity 350 of the cone, so that the fluid in the inner cavity 350 of the cone is sprayed outward through the micropore array 310.

[0060] A sealing head 360 is disposed on the top side of the relatively small cross-section of the truncated cone cavity 350, sealing the end of the truncated cone cavity 350. One end of the sealing head 360 extends toward the bottom side of the truncated cone cavity 350 and abuts against the end of the main channel 320. The outer circumferential surface of the sealing head 360 is provided with a plurality of straight grooves 361 along the axial direction. The straight grooves 361 are arranged in a circumferential array along the sealing head 360. One end of each straight groove 361 is connected to the main channel 320, and the other end is connected to the truncated cone cavity 350, so that fluid from the main channel 320 enters the truncated cone cavity 350 through the straight grooves 361.

[0061] In this embodiment, the massage head has an axial main channel (connecting to the first water outlet) and a bypass channel (connecting to the second water outlet). The larger bottom (the side with the larger cross-section) of the truncated cone cavity faces the connector, and the smaller top (the side with the smaller cross-section) faces the massage head. Microholes are provided on the side wall of the truncated cone. The sealing head is located on the smaller top side, sealing the end. Its lower end (larger end) extends and abuts against the end of the main channel. A straight groove is opened on the outer periphery, and the water flow in the main channel turns through the straight groove to enter the inner cavity of the truncated cone.

[0062] This embodiment converts axial water flow into radial flow into the frustum-shaped inner cavity, ensuring uniform distribution. The straight groove array both redirects and homogenizes the flow rate, while the sealing head simultaneously seals the top of the inner cavity, preventing water from directly entering from the end. The water flow is uniformly redirected, the pressure distribution within the cavity is consistent, the flow rates at each micropore are similar, the structure is compact, and no additional flow-diverting components are required.

[0063] In some embodiments, such as Figure 3 As shown, the cavity wall of the frustum 350 is inclined, and the micropore array 310 is formed on the inclined surface; when the bypass channel supplies water, the fluid is sprayed onto the inclined surface of the frustum 350 after passing through the bypass channel 330, and the micropore array 310 is cleaned by impact.

[0064] In this embodiment, the inner wall of the truncated cone is an inclined surface (with a conical angle relative to the axis). The bypass channel outlet faces this inclined surface, and the water flow directly impacts the micropore array on the inclined surface, using the impact force to wash away the deposits adhering to the inner wall of the micropores. During operation, the switching valve on the handle switches the water source to the bypass channel. Water is sprayed towards the inclined surface of the truncated cone's inner cavity through the bypass channel and its outlet. The high-speed water flow impacts the micropore area, creating a pressure difference and scouring effect inside and outside the micropores, causing the deposits to detach, and the mixture to be discharged from the micropores. By directly impacting the inclined surface where the micropores are located with the bypass water flow, cleaning is achieved using fluid kinetic energy, eliminating the need for additional components.

[0065] In some embodiments, such as Figure 3 As shown, the bottom side of the inner cavity 350 of the cone is provided with an annular groove 351, and part of the groove opening of the annular groove 351 is aligned with the micropore array 310. The outlet of the bypass channel 330 extends axially to connect with the annular groove 351.

[0066] In this embodiment, an annular groove is provided at the bottom plane of the inner cavity of the cone. The groove opening is aligned with the micropore array in the axial direction. The outlet of the bypass channel extends axially and connects to the annular groove. During self-cleaning, water enters the annular groove from the bypass channel and then sprays out from the groove opening (towards the inclined surface) to form a water curtain or uniformly impact the micropore array.

[0067] In some embodiments, such as Figure 4 As shown, the number of straight grooves 361 opened on the outer periphery of the sealing head 360 is 4-8. Each straight groove 361 is distributed at equal angles along the circumference. The bottom side of the straight groove 361 is located within the inner diameter of the main channel 320, so that a circumferential array of water channels is formed between the main channel 320 and the sealing head 360.

[0068] In this embodiment, the bottom of the straight groove is located within the inner diameter of the main channel, that is, the outer diameter of the plug head is larger than the inner diameter of the main channel, and the distance between the bottom of the groove and the axis of the plug head is smaller than the inner radius of the main channel. This allows the end of the straight groove to still connect with the main channel after the main channel and the end of the plug head are in contact, forming a circumferential array of water channels, which evenly distributes the flow and reduces eddies.

[0069] In some embodiments, such as Figure 3 and Figure 4 As shown, the end port of the main channel 320 is provided with a first chamfered bevel, and the end of the sealing head 360 facing the main channel 320 is provided with a second chamfered bevel 362 that matches the first chamfered bevel. The sealing head 360 is inserted from the head of the massage head 300, so that the second chamfered bevel 362 abuts against and is positioned with the first chamfered bevel. The chamfer on the inner edge of the end port of the main channel and the chamfer on the outer edge of the end of the sealing head 360 are angle-matched. During assembly, the sealing head is inserted from the head of the massage head until the two bevels contact, achieving axial and radial positioning. The bevel contact provides a self-centering function, ensuring that the sealing head is coaxial with the main channel, resulting in high assembly accuracy, ensuring unobstructed water flow, and facilitating rapid assembly during mass production.

[0070] In some embodiments, the end port of the main channel is provided with a one-way valve (not shown in the figure) for the fluid in the main channel to flow unidirectionally toward the inner cavity of the cone.

[0071] This embodiment features a one-way valve at the end of the main channel (near the inner cavity of the cone), allowing massage water to flow from the main channel to the inner cavity and preventing fluid in the inner cavity from flowing back into the main channel. Various miniature one-way valves are known in the art, such as spring-loaded, duckbill, and ball valves, which will not be described in detail in this embodiment. Massage and self-cleaning share the same inner cavity. During self-cleaning, the bypass pressure may be higher than the main channel pressure. Without a one-way valve, wastewater may flow back into the main channel and even the handle, causing contamination. This embodiment prevents the bypass high-pressure water from flowing back into the main channel during self-cleaning, ensuring water path isolation and avoiding cross-contamination.

[0072] In some embodiments, such as Figures 1 to 3 As shown, the head of the massage head 300 is also provided with a locking ring 370. The locking ring 370 is sleeved on the outside of the sealing head 360 and fixedly connected to the massage head 300, locking the sealing head 360 to the end of the main channel 320.

[0073] In this embodiment, the locking ring is a ring-shaped part that fits over the head of the massage head and is fixed to the massage head body by threads, snaps, or ultrasonic welding. The inner edge of the locking ring presses against the sealing head to prevent the sealing head from moving axially backward, ensuring reliable fixation and preventing loosening.

[0074] In some embodiments, the handle is provided with a switching valve, which has a first working position and a second working position. In the first working position, the main flow channel is connected to the water source, and in the second working position, the bypass flow channel is connected to the clean water source. The switching valve is a manual lever type, rotary type, or push-button type valve structure.

[0075] In this embodiment, the switching valve is located on the handle, which controls the water source to connect to the main channel or the bypass channel. The two channels do not flow water at the same time (or can be designed to flow at the same time, but usually one is selected). The operation is intuitive and the modes are clear.

[0076] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
