DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 8 The present invention provides a technical solution: a nasal cleaning device for patients, comprising an outer shell and an olive plug 12 thereon for injecting cleaning liquid into the nasal cavity of the patient, wherein the outer shell is provided with a variable structure for changing the outflow amount of the cleaning liquid in the olive plug 12;

[0030] The variable structure includes a base 1 fixedly connected to the outer shell, a horizontal sliding seat 2 is provided on the base 1 for horizontal reciprocating motion, a groove body 1 for horizontal sliding seat 2 to slide horizontally is provided on the base 1, a middle horizontal axis 3 is provided on the horizontal sliding seat 2 for synchronous horizontal reciprocating motion and free rotation, and a liquid supply component for injecting cleaning liquid into the olive plug 12 is provided on the middle horizontal axis 3;

[0031] One side of the base 1 is provided with an air compressor component for increasing the pressure in the patient's oral cavity when the cleaning solution is injected, and the side of the base 1 away from the olive plug 12 is provided with a distance adjustment component for changing the horizontal lateral movement distance of the sliding seat 2.

[0032] like Figure 1 - Figure 3As shown, when cleaning the patient's nasal cavity, the olive plug 12 is inserted deep into one side of the patient's nasal cavity, and the cleaning liquid enters the patient's nasal cavity through the olive plug 12 through the liquid supply component, thereby cleaning the nasal cavity on that side. At the same time, the process of the cleaning liquid entering the nasal cavity is not continuous, but intermittent, so as to more effectively remove the thick nasal mucus and bacterial toxins in the nasal cavity, reduce nasal infection and inflammation, and at the same time, avoid continuous flushing of the cleaning liquid, reducing the damage to the nasal mucosa.

[0033] At the same time, the horizontal stroke length of the horizontal sliding seat 2 and the central horizontal axis 3 arranged thereon is changed by the distance adjustment component, thereby changing the amount of cleaning liquid entering at a single time, thereby preventing the phenomenon of excessive pressure in the nasal cavity caused by a large amount of cleaning liquid being injected at a single time, thereby preventing the cleaning liquid from entering the Eustachian tube or the middle ear, and then causing otitis media.

[0034] When the cleaning liquid is poured into the patient's nasal cavity through the olive plug 12, natural air from the outside is input into the patient's cavity through the air compressor component, thereby increasing the pressure in the patient's mouth, making it easier for the cleaning liquid to flow out of the nasal cavity instead of entering the mouth, thereby avoiding choking or swallowing of the patient.

[0035] In one of the more preferred embodiments, the liquid supply component includes a lever 22 that swings back and forth in the horizontal direction, a connecting rod 21 is provided on the lever 22, the connecting rod 21 rotates on a fixed axis on the lever 22, and one end of the connecting rod 21 away from the lever 22 rotates on a fixed axis on the transverse sliding seat 2, a No. 1 rack 6 is provided on the transverse sliding seat 2, and two grooves for the horizontal longitudinal movement of the No. 1 rack 6 are provided on the transverse sliding seat 2, the transverse sliding seat 2 is fixedly connected to the side support block 4, the middle transverse axis 3 rotates on the side support block 4, a longitudinal gear 5 is fixedly sleeved on the middle transverse axis 3, the longitudinal gear 5 meshes with the No. 1 rack 6, and the No. 1 rack 6 is provided with a guide component for limiting its movement trajectory.

[0036] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, by the lever 22 swinging back and forth in the horizontal direction, the connecting rod 21 is driven to deflect back and forth in the horizontal direction, and the transverse sliding seat 2 can be driven to reciprocate along the laying direction of the base 1. The transverse sliding seat 2 is provided with a central transverse axis 3, which drives the central transverse axis 3 and the transverse sliding seat 2 to move horizontally synchronously. At the same time, a longitudinal gear 5 is provided on the central transverse axis 3, and the longitudinal gear 5 is engaged with the No. 1 rack 6. While the No. 1 rack 6 follows the synchronous horizontal lateral movement of the transverse sliding seat 2, under the restriction of the guide assembly, the No. 1 rack 6 can be synchronously displaced in the horizontal longitudinal direction, and then the central transverse axis 3 is driven to rotate in the vertical direction through the longitudinal gear 5.

[0037] Furthermore, the side of the base 1 away from the connecting rod 21 is fixedly connected to the water cylinder 7, and a push plate 8 is provided on the water cylinder 7, and the push plate 8 is fixedly connected to the central transverse axis 3. The push plate 8 is in sliding contact with the inner wall of the water cylinder 7, and the central transverse axis 3 includes an integrally formed spline portion 301. A hollow tube 9 is provided on the water cylinder 7, and a circular groove for the hollow tube 9 to pass through and rotate is provided on the water cylinder 7. The hollow tube 9 includes an integrally formed guide portion 901, and a spline groove for the spline portion 301 to slide laterally is provided on the guide portion 901. The water cylinder 7 is fixedly connected to the plug nose plate 14, and the hollow tube 9 slides through the plug nose plate 14 and is fixedly penetrated by the olive plug 12, and the olive plug 12 is provided with a plurality of groups of equidistantly arranged lateral water outlet holes 13.

[0038] like Figure 1 - Figure 4 As shown, when the middle horizontal axis 3 reciprocates horizontally and rotates synchronously, the horizontal movement of the middle horizontal axis 3 drives the push plate 8 to move horizontally in the water cylinder 7, thereby forcing the cleaning liquid in the water cylinder 7 out, so that the cleaning liquid in the water cylinder 7 can flow into the olive plug 12 and flow into the patient's nasal cavity through the multiple groups of lateral water outlet holes 13 opened on the olive plug 12.

[0039] At the same time, when the central horizontal axis 3 rotates in the vertical direction, it can drive the integrally formed spline portion 301 to rotate synchronously, and the spline portion 301 drives the hollow tube 9 to rotate vertically synchronously through the guide portion 901, and the olive plug 12 is arranged at the end of the hollow tube 9. Therefore, when the cleaning liquid flows into the patient's nasal cavity through the olive plug 12, the rotation of the olive plug 12 can increase the coverage of the cleaning liquid, so that the cleaning liquid can contact all angles of the nasal cavity, thereby reducing the dead angle of cleaning, thereby removing more secretions and foreign matter, and at the same time, it can increase the impact force of the cleaning liquid, so that the cleaning liquid can more effectively flush the surface of the nasal cavity, thereby removing more bacteria and viruses.

[0040] It should be noted that in order to ensure that the flow direction of the cleaning liquid is fixed, the hollow tube 9 is provided with a plurality of groups of runoff holes 11 penetrating the internal space of the water cylinder 7. The hollow tube 9 is fixedly connected to the side through-tube 10 at the position corresponding to the runoff holes 11. The water cylinder 7 is provided with a water inlet pipe, and the outer shell is fixedly connected to the water tank. The two ends of the water inlet pipe are respectively fixed to pass through the water tank and the water cylinder 7.

[0041] like Figure 3 and Figure 4As shown, when the middle horizontal axis 3 drives the push plate 8 to move forward in the water cylinder 7, the cleaning liquid in the water cylinder 7 is squeezed, and the cleaning liquid enters the hollow tube 9 through the side passage 10 and the runoff hole 11, and flows into the nasal cavity from the lateral water outlet 13 on the olive plug 12 as the push plate 8 continues to move. At the same time, when the middle horizontal axis 3 drives the push plate 8 to move reversely in the water cylinder 7, the cleaning liquid in the water tank enters the water cylinder 7 through the water inlet pipe. It should be noted that a one-way valve is fixedly connected to the water inlet pipe and the side passage 10. By setting two sets of one-way valves, the flow direction of the cleaning liquid is restricted, so that the cleaning liquid can only enter the water cylinder 7 from the water tank and flow into the nasal cavity through the olive plug 12.

[0042] Based on the liquid supply component embodiment, the guide component includes a swing circle 32 arranged on one side of the base 1, the swing circle 32 rotates on a fixed axis on the protective shell, the side circumference of the swing circle 32 is fixedly connected to the guide column 16, the guide column 16 is slidably sleeved with a guide seat 15, and the end of the No. 1 rack 6 rotates on a fixed axis on the guide seat 15.

[0043] like Figure 1 and Figure 2 As shown, when the transverse sliding seat 2 moves horizontally, it can drive the No. 1 rack 6 slidably connected thereto to move synchronously horizontally. At the same time, the end of the No. 1 rack 6 rotates on the guide seat 15, and the guide seat 15 can only move along the direction of the guide column 16. Therefore, the No. 1 rack 6 can undergo a certain displacement in the horizontal longitudinal direction when it moves horizontally, and its displacement in the horizontal longitudinal direction is related to the angle between the guide column 16 and the transverse sliding seat 2.

[0044] By displacing the No. 1 rack 6 in the horizontal and longitudinal directions, the longitudinal gear 5 meshing therewith is driven to rotate in the vertical direction, thereby driving the middle horizontal axis 3, the hollow tube 9 and the olive plug 12 to rotate synchronously, so that when the cleaning liquid enters the nasal cavity through the olive plug 12, the rotation of the olive plug 12 can increase the impact force of the cleaning liquid, so that the cleaning liquid can more effectively flush the surface of the nasal cavity, thereby removing more bacteria and viruses.

[0045] Based on the guide assembly embodiment, the air compressor assembly includes a support plate 19, which is arranged on the side of the horizontal sliding seat 2 away from the guide column 16. The base 1 is provided with a groove body 3 for the support plate 19 to slide horizontally. The support plate 19 is fixedly connected to the air cylinder 18, and the inner wall of the air cylinder 18 slides in contact with the piston plate 17. The end of the No. 1 rack 6 away from the guide seat 15 is fixedly connected to the piston plate 17. The air cylinder 18 is provided with an air outlet pipe 20 and an air inlet pipe, and the air outlet pipe 20 and the air inlet pipe are fixedly passed through the air cylinder 18.

[0046] like Figure 1 , Figure 2 and Figure 5As shown, when the No. 1 rack 6 moves in the horizontal longitudinal direction, it can drive the piston plate 17 fixedly connected at its end to move in the air cylinder 18, and the gas in the air cylinder 18 is pressed into the air outlet pipe 20 through the horizontal and longitudinal movement of the piston plate 17. When the nasal cleaning device is actually used, the air outlet end of the air outlet pipe 20 is fixed on the outer shell, and the air outlet end of the air outlet pipe 20 is placed below the olive plug 12. In actual use, the air outlet end of the air outlet pipe 20 is directed toward the patient's oral cavity. The main function of the outer shell is to retain the internal components and provide support for the internal components, so it is not shown in the figure.

[0047] Therefore, when the cleaning liquid is poured into the patient's nasal cavity, natural air can be simultaneously input into the patient's oral cavity, thereby increasing the pressure in the patient's oral cavity and making it easier for the cleaning liquid to flow out of the nasal cavity instead of entering the oral cavity, thereby avoiding the patient from choking or swallowing. It should be noted that a one-way valve is fixed on both the outlet pipe 20 and the inlet pipe, and the one-way valve is used to limit the direction of gas flow to prevent the gas from entering the air cylinder 18 from the inlet pipe, thereby preventing the cleaning liquid from entering the oral cavity under the action of the pressure difference due to the low air pressure in the oral cavity.

[0048] On the basis of the air compressor assembly embodiment, the outer shell is provided with an eccentric circle 25 that is driven by a motor to rotate freely, the eccentric circle 25 is provided with a positioning column 26, the eccentric circle 25 is provided with a circular groove 251 for the positioning column 26 to slide, the positioning column 26 is fixedly connected to the end of the lever 22 away from the connecting rod 21, the side of the base 1 away from the water cylinder 7 is fixedly connected to the horizontal slide frame 31, the horizontal slide frame 31 is provided with a support 24, the lever 22 is provided with a makeshift groove 23 for the support 24 to slide, the end of the lever 22 away from the connecting rod 21 is fixedly rotated on the positioning rod 27, the end of the positioning rod 27 away from the lever 22 is fixedly rotated on the vertical support plate 33, and the vertical support plate 33 is fixedly connected to the horizontal slide frame 31.

[0049] The pitch adjustment assembly includes a No. 2 rack 30 arranged on a transverse slide 31, and a rectangular groove is opened on the transverse slide 31 for the No. 2 rack 30 to slide horizontally. A transverse gear 29 driven by a motor is provided on one side of the No. 2 rack 30, and the transverse gear 29 meshes with the No. 2 rack 30. The transverse gear 29 is coaxially fixed to the swing circle 32, and the upper surface of the No. 2 rack 30 is fixedly connected to the L-shaped rod 28, and the support 24 rotates on the L-shaped rod 28.

[0050] like Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8As shown, the eccentric circle 25 is driven to rotate freely in the horizontal direction by a group of motors. A positioning column 26 is provided on the eccentric circle 25, and the positioning column 26 is slidably connected to the eccentric circle 25 through a circular groove 251, and then the lever 22 is driven to swing back and forth in the horizontal direction through the positioning column 26. When the lever 22 swings, the connecting rod 21 at one end away from the positioning column 26 can swing back and forth in the horizontal direction driven by the lever 22, thereby driving the horizontal slide seat 2 to reciprocate in the horizontal lateral direction. At the same time, a positioning rod 27 is provided on the lever 22. Since one end of the positioning rod 27 is fixedly rotated on the horizontal slide frame 31, the stability of the lever 22 during swinging can be ensured through the setting of the positioning rod 27.

[0051] It should be noted that the swing fulcrum of the lever 22 is the rotation point of the support 24 on the L-shaped rod 28. Therefore, by changing the relative position of the support 24 and the lever 22, the swing amplitude of the end of the lever 22 where the positioning column 26 is located can be changed under the premise that the swing amplitude of the front end of the lever 22 where the positioning column 26 is located remains unchanged.

[0052] At the same time, another motor drives the transverse gear 29 to rotate freely in the horizontal direction, thereby driving the No. 2 rack 30 meshing with it to move in the horizontal longitudinal direction. The No. 2 rack 30 is fixedly connected with an L-shaped rod 28. By changing the horizontal longitudinal position of the L-shaped rod 28, the relative position of the support 24 and the lever 22 is changed, thereby changing the swing amplitude of the end of the lever 22 where the connecting rod 21 is located, thereby changing the horizontal lateral movement stroke spacing of the transverse sliding seat 2.

[0053] Moreover, when the horizontal movement stroke interval of the transverse sliding seat 2 becomes smaller, the single injection volume of the cleaning liquid can be changed. At the same time, the transverse gear 29 coaxially fixes the swing circle 32, and the transverse gear 29 drives the swing circle 32 to deflect, thereby changing the direction of the guide column 16. When the transverse sliding seat 2 moves horizontally, the horizontal and longitudinal movement distance of the No. 1 rack 6 is related to the angle between the guide column 16 and the transverse sliding seat 2. Therefore, by changing the direction of the guide column 16, the horizontal and longitudinal movement distance of the No. 1 rack 6 and the piston plate 17 is changed, thereby changing the single amount of gas delivered to the patient's mouth, thereby avoiding too little gas delivery to prevent the cleaning liquid from entering the mouth, and avoiding too much gas delivery to cause discomfort in the patient's throat.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
