Without the protection of the nasal cavity, bacteria and viruses directly enter the lower respiratory tract and lungs. In this context, nasal care has received more and more attention from the public. Proper nasal cleaning can effectively improve the function of the nasal mucosa, enhance the motility of nasal cilia, and improve its bacteria and toxin removal effects.

[0004] Taking the above technology as an example, most nasal irrigators are composed of a liquid storage structure and an atomization structure. However, during the use of the nasal irrigator, the user needs to tilt the nasal irrigator to various angles for easy operation. As the liquid inside the liquid storage structure decreases, the user may accidentally cause the liquid inside the liquid storage structure to tilt, resulting in insufficient liquid at the end of the extraction tube in the atomization structure, resulting in insufficient water supply to the atomization structure, affecting the stability of the nasal irrigation work. Summary of the invention

Sliding blocks are provided inside the three vertical sliding grooves, and the sealing plate is pressed to increase the friction between the sealing plate and the mask mounting cavity. Then, the water supply pump is rotated to rotate the installed water supply pipe to make the sliding block return to the inside of the vertical sliding groove, so that the sealing plate is pushed by the supporting spring to slide up and down on the outside of the water supply pipe, and the bottom ends of the three sliding blocks extend to the inside of the sealing plate and are fixedly connected to the sealing plate.

[0010] Preferably, an elastic telescopic tube is sleeved on the outer side of the three support springs, and the elastic telescopic tube is fixedly connected between the sealing plate and the ultrasonic atomizer. The elastic telescopic tube can be retracted to seal and protect the support spring, and the outer side of the elastic telescopic tube remains smooth after elastic deformation, so the outer side of the elastic telescopic tube can be quickly cleaned, and the bottom end of the elastic telescopic tube extends to the outside of the outer shell.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present application, the sealing plate is pushed to move by the rebounding support spring. Under the action of the sealing plate, the physiological saline is always collected at the bottom of the inner cavity of the liquid storage tank, which plays a role in collecting the physiological saline to the bottom of the water supply pipe, ensuring that the water supply pipe can stably extract the physiological saline, avoiding the insufficient water source at the bottom of the water supply pipe due to the tilt of the liquid storage tank and the reduction of the physiological saline inside the liquid storage tank during the use of the electric nasal atomizer, and the unstable water supply of the water supply pump to the ultrasonic atomizer, ensuring the stability of the mist sprayed by the atomization structure, improving the working stability of the electric nasal atomizer, and ensuring the efficiency of the use of the physiological saline stored in the liquid storage tank, reducing the waste caused by replacing a large amount of physiological saline in the liquid storage tank with new physiological saline before it is used up.

[0017] 2. In the present application, the displacement sensor works to detect the distance between the sealing plates for its own use, and the sealing plates push the saline solution to the bottom of the inner cavity of the liquid storage tank, so the movement distance of the sealing plates represents the amount of saline solution inside the liquid storage tank. The displacement sensor detects a value that is fed back to the electrically connected controller. When the value detected by the displacement sensor reaches a preset value inside the controller, the speaker on the controller works to sound an alarm to remind the staff that the amount of saline solution inside the liquid storage tank is small, and to remind the staff to replenish the saline solution inside the liquid storage tank in time to avoid the situation where the water supply pump and the ultrasonic nebulizer work ineffectively due to the lack of saline solution, thereby reducing the probability of damage to the water supply pump and the ultrasonic nebulizer.

[0018] 3. The electric nasal atomizer irrigator provided in the present application, when the sealing plate is not needed, push the sealing plate into the limiting ring, at this time the sealing plate and the battery are tightly attached and their up and down movement is limited, and the sliding block fixedly connected inside the sealing plate moves to one side of the arc-shaped limiting groove, and then the water supply pipe is rotated to make the sliding block enter the arc-shaped limiting groove, at this time the up and down movement of the sliding block is limited, and the up and down movement of the sealing plate is limited, and under the interference fit between the sliding block and the water supply pipe and the downward thrust applied by multiple support springs, the sealing plate is limited to the outside of the water supply pipe and cannot move up and down, at this time the sealing plate is installed inside the limiting ring, the state of the sealing plate can be controlled as needed, and the sealing plate can be used flexibly.

[0019] 4. In the present application, the electric push rod pushes the sealing circular plate and the limit rod fixedly connected to the bottom end of the sealing circular plate to move downward, so that the limit rod moves downward and is inserted into the limit circular groove. Therefore, when the atomization structure is working, the three limit rods are in the three limit circular grooves opened in the liquid storage tank. At this time, the liquid storage tank cannot rotate inside the outer shell, and the liquid storage tank can be separated from the outer shell only when it rotates. Therefore, when the atomization structure is working, the liquid storage tank will not be separated from the outer shell due to the rotation caused by the accidental operation of the staff, thereby ensuring the stable and efficient operation of the electric nasal atomization irrigator composed of the atomization structure and the liquid storage structure, and reducing the waste of physiological saline inside the liquid storage tank caused by accidents.

DETAILED DESCRIPTION

[0035] 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.

[0036] Example: Figure 1-Figure 14As shown, the present invention provides a technical solution of an electric nasal atomizing irrigator, including a liquid storage structure 2 and an atomizing structure 1, the atomizing structure 1 including a shell 11 and an ultrasonic atomizer 12, the inner cavity of the shell 11 is fixedly connected to a limiting ring 119, three electric push rods 121 are installed on the limiting ring 119, and a limiting plug rod 123 is arranged at the piston end of the electric push rod 121, a sealing plate 18 is arranged at the bottom of the shell 11, three sliding vertical grooves 17 are opened on the outer side of the water supply pipe 16, the three sliding vertical grooves 17 correspond to the three arc-shaped limiting grooves 110 one by one and are connected to each other, sliding blocks 19 are arranged inside the three sliding vertical grooves 17, the bottom ends of the three sliding blocks 19 extend to the inside of the sealing plate 18 and are fixedly connected to the sealing plate 18, the sealing plate 18 and the water supply pipe 16 are slidably installed together, the outer side of the water supply pipe 16 is opened to three arc-shaped limiting grooves 110, three support springs 112 are fixedly connected to the top of the sealing plate 18, and a displacement sensor 113 is inserted into one of the support springs 112;

[0037] The limiting ring 119 is provided with three circular mounting grooves 120 , and electric push rods 121 are arranged inside the three circular mounting grooves 120 . The electric push rods 121 are fixedly connected to the limiting ring 119 , and a sealing circular plate 122 is fixedly connected to the piston end of the electric push rod 121 , and the bottom end of the sealing circular plate 122 is fixedly connected to the limiting plug rod 123 .

[0038] Specifically, when using the electric nasal atomizing irrigator composed of the atomizing structure 1 and the liquid storage structure 2, the liquid storage tank 21 in the liquid storage structure 2 is operated separately. After a proper amount of physiological saline is poured into the liquid storage tank 21, the shell 11 in the atomizing structure 1 and the liquid storage tank 21 are vertically arranged, and an ultrasonic atomizer 12 is fixedly installed inside the shell 11. A water supply pump 15 is installed at the water inlet end of the ultrasonic atomizer 12 to provide sufficient water source for the ultrasonic atomizer 12 to produce mist. A water supply pipe 16 is rotatably installed at the water inlet end of the water supply pump 15, and one end of the water supply pipe 16 extends to the bottom of the shell 11, so the user first inserts the bottom end of the water supply pipe 16 installed on the shell 11 into the liquid storage tank 21;

[0039] And the three sliding vertical grooves 17 opened on the outside of the water supply pipe 16 are all provided with sliding blocks 19, and the bottom ends of the three sliding blocks 19 extend into the sealing plate 18 and are fixedly connected to the sealing plate 18, such as Figure 7As shown, the sealing plate 18 can slide up and down on the outside of the water supply pipe 16 under the limit of the three sliding blocks 19. When the water supply pipe 16 is inserted into the liquid storage tank 21, the sealing plate 18 will enter the liquid storage tank 21. After the sealing plate 18 supported by the three supporting springs 112 moves down and contacts the surface of the physiological saline solution inside the liquid storage tank 21, since the outer wall of the sealing plate 18 is tightly attached to the inner wall of the liquid storage tank 21, the force applied to the sealing plate 18 by the three supporting springs 112 is limited. Therefore, under the action of the physiological saline solution inside the liquid storage tank 21, the sealing plate 18 stops moving down, the water supply pipe 16 continues to move down, and the sealing plate 18 moves toward the inside of the housing 11.

[0040] When the bottom of the outer shell 11 is tightly attached to the top of the liquid storage tank 21, the liquid storage tank 21 is rotated. Since a threaded structure 22 is formed on the top of the outer side of the liquid storage tank 21 and a threaded structure 124 is formed on the bottom of the inner cavity of the outer shell 11, the top of the rotating liquid storage tank 21 is inserted into the outer shell 11, and the liquid storage tank 21 and the outer shell 11 are threadedly connected together through the threaded structure 22 and the threaded structure 124, thereby completing the assembly of the outer shell 11 and the liquid storage tank 21.

[0041] A limiting circular ring 119 is fixedly connected inside the shell 11. When the top of the liquid storage tank 21 contacts the limiting circular ring 119, the rotation of the liquid storage tank 21 is limited, and the installation between the liquid storage tank 21 and the shell 11 is completed. At this time, the three limiting circular grooves 23 opened at the top of the liquid storage tank 21 are respectively aligned with the three circular installation grooves 120 opened at the bottom of the sliding block 19. When the button 126 set on one side of the shell 11 is pressed, the controller 117 electrically connected to the button 126 works, and the atomization structure 1 enters the working state. The water supply pump 15, the ultrasonic atomizer 12 displacement sensor 113 and the three electric push rods 121 set inside the three circular installation grooves 120 in the atomization structure 1 work, and the piston end of the electric push rod 121 fixedly connected to the outer wall and the limiting circular ring 119 is fixedly connected to the sealing circular plate 122, as shown in FIG. Fig.10 As shown, the working electric push rod 121 pushes the sealing circular plate 122 and the limiting plug 123 fixedly connected to the bottom end of the sealing circular plate 122 to move downward, so that the limiting plug 123 moves downward and is inserted into the limiting circular groove 23. Therefore, when the atomization structure 1 is working, the three limiting plugs 123 are inside the three limiting circular grooves 23 opened in the liquid storage tank 21. At this time, the liquid storage tank 21 cannot rotate inside the outer shell 11, and the liquid storage tank 21 can only be separated from the outer shell 11 by rotating. Therefore, when the atomization structure 1 is working, the liquid storage tank 21 will not be separated from the outer shell 11 due to the rotation caused by the operator's accidental operation, thereby ensuring that the electric nasal atomization irrigator composed of the atomization structure 1 and the liquid storage structure 2 works stably and efficiently, and reducing the waste of physiological saline in the liquid storage tank 21 caused by accidents.

[0042] The working water supply pump 15 extracts the physiological saline in the liquid storage tank 21 through the water supply pipe 16, and the water supply pump 15 transports the physiological saline to the ultrasonic atomizer 12. The ultrasonic atomizer 12 atomizes the physiological saline and discharges it through the mist output pipe 13 installed at the air outlet end, and the patient's nasal cavity is rinsed by the water mist. The rinsing process has little irritation, and the spray is uniform, soft and comfortable, and has a wide range of applications. As the working time of the atomization structure 1 increases, the physiological saline in the liquid storage tank 21 decreases, and the sealing plate 18 supported by the contracted support spring 112 is pushed by the rebounded support spring 112 to move, and the physiological saline is always collected in the liquid storage tank 21 under the action of the sealing plate 18. The bottom of the cavity serves to collect the saline solution to the bottom of the water supply pipe 16, ensuring that the water supply pipe 16 can stably extract the saline solution, avoiding the insufficient water source at the bottom of the water supply pipe 16 due to the tilt of the liquid storage tank 21 and the reduction of the saline solution inside the liquid storage tank 21 during the use of the electric nasal atomizer irrigator, and the unstable water supply from the water supply pump 15 to the ultrasonic atomizer 12, ensuring the stability of the mist sprayed by the atomization structure 1, improving the working stability of the electric nasal atomizer, and ensuring the efficiency of the use of the saline solution stored in the liquid storage tank 21, reducing the waste caused by replacing the large amount of saline solution in the liquid storage tank 21 with new saline solution before it is used up.

[0043] In addition, an elastic telescopic tube 111 is sleeved on the outside of the three support springs 112. The elastic telescopic tube 111 is fixedly connected between the sealing plate 18 and the ultrasonic atomizer 12. The elastic telescopic tube 111 can be retracted to seal and protect the support spring 112. After the elastic deformation of the elastic telescopic tube 111, the outside remains smooth, and the outside of the elastic telescopic tube 111 can be quickly cleaned; and a displacement sensor 113 is inserted into one of the support springs 112. The displacement sensor 113 is fixedly installed with the outer wall of the ultrasonic atomizer 12. The relative position between the displacement sensor 113 and the ultrasonic atomizer 12 remains unchanged. When the atomization structure 1 is working, the displacement sensor 113 works synchronously, and the working detection of the displacement sensor 113 The distance between the sealing plates 18 is used for its own purpose, and the sealing plates 18 push the saline solution to the bottom of the inner cavity of the liquid storage tank 21, so the movement distance of the sealing plates 18 represents the amount of saline solution inside the liquid storage tank 21, and the displacement sensor 113 detects a value and feeds it back to the electrically connected controller 117. When the value detected by the displacement sensor 113 reaches a preset value inside the controller 117, the speaker on the controller 117 works to sound an alarm, reminding the staff that the amount of saline solution inside the liquid storage tank 21 is small, and reminding the staff to replenish the saline solution inside the liquid storage tank 21 in time, so as to avoid the situation where the water supply pump 15 and the ultrasonic nebulizer 12 work ineffectively due to the lack of saline solution, thereby reducing the probability of damage to the water supply pump 15 and the ultrasonic nebulizer 12.

[0044] In addition, the axis of the mist output tube 13 is at an angle of 45° to the axis of the shell 11. The user can hold the liquid storage tank 21 and move the mist output tube 13 from the side of the patient's head to the patient's nasal cavity, which is convenient for flushing the nasal cavity of female patients. A mask mounting cavity 14 is provided on the shell 11, and the mask mounting cavity 14 is used to install a corresponding mask.

[0045] A battery 114 is arranged on the outside of the water supply pump 15. The battery 114 is fixedly installed inside the shell 11 to provide power for the ultrasonic atomizer 12, the water supply pump 15 and other structures. The outside of the shell 11 is fixedly connected to a charging port 127, and the battery 114 is charged through the charging port 127; two indicator lights 125 are fixedly connected to one side of the shell 11. When the battery 114 has sufficient power, a controller 117 electrically connected to the battery 114 controls one of the indicator lights 125 to light up green. When the power inside the battery 114 is lower than 95%, the controller 117 electrically connected to the battery 114 controls the other indicator light 125 to light up red, reminding the staff to charge the battery 114.

[0046] Three arc-shaped limit grooves 110 are provided on the outside of the water supply pipe 16, and the three vertical sliding grooves 17 correspond to the three arc-shaped limit grooves 110 one by one and are interconnected. Figure 8 As shown, when the sealing plate 18 is not needed, the sealing plate 18 is pushed into the limiting ring 119. At this time, the sealing plate 18 and the battery 114 are tightly attached to each other and their up and down movement is limited. The sliding block 19 fixedly connected to the sealing plate 18 moves to one side of the arc-shaped limiting groove 110. Then, the water supply pipe 16 is rotated to allow the sliding block 19 to enter the arc-shaped limiting groove 110. At this time, the sliding block 19 is limited in its up and down movement, and the sealing plate 18 is limited in its up and down movement. Under the interference fit between the sliding block 19 and the water supply pipe 16 and the downward thrust applied by the plurality of support springs 112, the sealing plate 18 is locked. Under the action of the pressure relief valve 114, the sealing plate 18 is limited on the outside of the water supply pipe 16 and cannot move up and down. At this time, the sealing plate 18 is installed inside the limiting ring 119; when the sealing plate 18 needs to be used, the sealing plate 18 is pressed to increase the friction between the sealing plate 18 and the mask mounting cavity 14, and then the water supply pump 15 is rotated to rotate the installed water supply pipe 16, so that the sliding block 19 returns to the inside of the sliding vertical groove 17, and the sealing plate 18 is pushed by the support spring 112 to slide up and down on the outside of the water supply pipe 16. The state of the sealing plate 18 can be controlled as needed, and the sealing plate 18 can be used flexibly.

[0047] A heat dissipation filter 118 is fixedly connected to the outside of the housing 11 , and the heat dissipation filter 118 is arranged on one side of the mounting groove 116 . The heat dissipated by the controller 117 during operation is dissipated through the mounting groove 116 and the heat dissipation filter 118 , and the heat dissipation filter 118 prevents dust from entering the mounting groove 116 .

[0048] There are sealing circular plates 122 inside the three circular installation grooves 120 . The outer wall of the sealing circular plates 122 contacts the limiting ring 119 to seal the circular installation grooves 120 and prevent impurities from accumulating inside the circular installation grooves 120 .

[0049] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
