DETAILED DESCRIPTION

[0024] This application is based on the inventor's discovery and understanding of the following facts and problems:

[0025] The nasal cleaning device in the related art requires different flow rates when flushing the inside of the nasal cavity due to different personal feelings and needs. If the water flow rate is too small, it may easily lead to incomplete cleaning and poor cleaning effect. If the water flow rate is too large, it will rush deep into the nasal cavity and cause the user to feel uncomfortable.

[0026] Specifically, the nasal cleaning device in the related art cannot reliably control the flow rate, resulting in the inability to meet the different needs of different users.

[0027] In addition, the nasal cleaning device in the related art has a fixed size of the drug delivery head that extends into the nasal cavity and cannot be adjusted according to the size of the nostrils of different patients. If the drug delivery head is too small, it cannot effectively clean the foreign matter in the nasal cavity. If the drug delivery head is too large, the friction inside the patient's nasal cavity will increase, reducing the patient's comfort and even causing a certain degree of damage to the patient's nasal mucosa.

[0031] The following describes a nasal cleaning device 1 according to an embodiment of the present invention with reference to the accompanying drawings.

[0032] like Figure 1-Figure 5 As shown, the nasal cavity cleaning device 1 according to an embodiment of the present invention includes a storage tank 10 , an adapter block 20 , a water suction pipe 30 , a flushing pipe 40 , a liquid driving device 50 and a flow regulating device 60 .

[0033] The adapter block 20 is mounted on the storage tank 10 and has a flow passage 21 defined therein. A suction pipe 30 is mounted on the adapter block 20 and extends into the storage tank 10, communicating with the flow passage 21. A flushing pipe 40 is mounted on the adapter block 20 and extends out of the storage tank 10, communicating with the flow passage 21. A liquid drive device 50 is mounted on the storage tank 10 and is adapted to drive the flow of liquid within the flow passage 21. A flow control device 60 is mounted on the storage tank 10 and is adapted to regulate the flow rate of liquid in the flow passage 21.

[0034] Specifically, the adapter block 20 is provided on the upper surface of the storage tank 10 (up and down directions are indicated by arrows in the figure), the suction pipe 30 extends downward from the adapter block 20, and the flushing pipe 40 extends upward from the adapter block 20. The liquid driving device 50 may be a water pump.

[0035] The reservoir 10 contains physiological saline or other nasal cleaning fluid. The irrigation tube 40 is inserted into the nasal cavity. The liquid drive device 50 drives the suction tube 30 to draw the liquid from the reservoir 10. The liquid passes through the flow channel 21 and is then ejected from the irrigation tube 40 to irrigate the user's nasal cavity. Simultaneously, the flow rate control device 60 adjusts the flow rate of the liquid in the flow channel 21, thereby regulating the flow rate of the liquid ejected from the irrigation tube 40.

[0036] According to the nasal cleaning device 1 of the embodiment of the present invention, by providing a flow regulating device 60, compared with the nasal cleaning device in the related art, the flow regulating device 60 can be used to adjust the flow of the medicinal liquid during flushing to meet the different needs of different users. It can not only avoid incomplete flushing and poor flushing effect caused by too small a flow, but also avoid excessive flow causing the medicinal liquid to rush into the deep nasal cavity and cause discomfort to the user, thereby improving the comfort of the user during use and improving the applicability of the nasal cleaning device 1.

[0037] In addition, by setting up an adapter block 20, setting a flow channel hole 21 in the adapter block 20, connecting the water suction pipe 30 and the flushing pipe 40 to the flow channel hole 21, and the liquid driving device 50 and the flow regulating device 60 both act on the flow channel hole 21, the adapter block 20 can be used to realize the connection of the water suction pipe 30, the flushing pipe 40, the liquid driving device 50 and the flow regulating device 60, thereby improving the integration of the nasal cleaning device 1.

[0038] Therefore, the nasal cleaning device 1 according to the embodiment of the present invention has the advantages of good cleaning effect, good comfort, strong applicability, and high integration.

[0039] The following describes a nasal cleaning device 1 according to a specific embodiment of the present invention with reference to the accompanying drawings.

[0040] In some specific embodiments of the present invention, Figure 1-Figure 5As shown, the nasal cavity cleaning device 1 according to an embodiment of the present invention includes a storage tank 10 , an adapter block 20 , a water suction pipe 30 , a flushing pipe 40 , a liquid driving device 50 and a flow regulating device 60 .

[0041] Specifically, if Figure 2-Figure 4 As shown, the flow regulating device includes an adjusting plate 61 and a driving device. The adjusting plate 61 is provided with an adjusting hole 611, the diameter of which is smaller than the diameter of the flow channel hole 21. The adapter block 20 is provided with a slot 22. The adjusting plate 61 is movably arranged in the slot 22 between an adjusting position and a circumventing position. When the adjusting plate 61 is in the adjusting position, the adjusting hole 611 is radially located inward of the flow channel hole 21. When the adjusting plate 61 is in the circumventing position, the adjusting plate 61 avoids the flow channel hole 21. The driving device is provided on the storage tank 10 and is suitable for driving the adjusting plate 61 to move between the circumventing position and the adjusting position. Specifically, the adjusting plate 61 is sealed with the slot 22 to prevent the liquid medicine from leaking from the slot 22. When the flow rate needs to be reduced, the drive device drives the adjustment plate 61 to the adjustment position, allowing the liquid medicine to pass through the adjustment hole 611. Since the diameter of the adjustment hole 611 is smaller than the flow channel hole 21, the flow rate of the liquid medicine passing through can be reduced. When the flow rate needs to be increased, the drive device drives the adjustment plate 61 to the avoidance position, allowing the adjustment plate 61 to avoid the flow channel hole 21, allowing the liquid medicine to pass through the flow channel hole 21, thereby maintaining a large flow rate. In this way, different liquid medicine flow rates can be switched by moving the adjustment plate 61, thereby achieving the adjustment of the liquid medicine flow rate.

[0042] More specifically, if Figure 3 As shown, the driving device includes a positioning block 62, a magnetic member 63, and an electromagnet 64. A positioning slot 621 is provided in the positioning block 62. The magnetic member 63 is connected to the adjustment plate 61 and is slidably disposed in the positioning slot 621. The electromagnet 64 is disposed in the positioning slot 621. When the electromagnet 64 is energized, the polarity of the electromagnet 64 and the magnetic member 63 are opposite, so as to drive the adjustment plate 61 to move toward the adjustment position. Specifically, the electromagnet 64 is disposed on the side of the positioning slot 621 away from the opening, and the magnetic member 63 is closer to the opening of the positioning slot 621 relative to the electromagnet 64. When the electromagnet 64 is energized, it pushes the magnetic member 63 toward the opening of the positioning slot 621, and the magnetic member 63 pushes the adjustment plate 61 to move toward the adjustment position. In this way, the adjustment plate 61 can be driven to move by electromagnetic means, which facilitates the miniaturization of the driving device and facilitates the realization of liquid-electric separation.

[0043] Furthermore, if Figure 3As shown, the driving device also includes an elastic member 65, which is suitable for driving the adjustment plate 61 to move toward the avoidance position. Specifically, after the electromagnet 64 is energized, the repulsive force between the electromagnet 64 and the magnetic member 63 is greater than the elastic force of the elastic member 65, and the adjustment plate 61 moves toward the adjustment position under the action of the repulsive force. After the electromagnet 64 is de-energized, the magnetic member 63 and the electromagnet 64 lose their repulsive force, and the adjustment plate 61 returns to the avoidance position under the elastic force of the elastic member 65. In this way, the elastic member 65 can be used to drive the adjustment plate 61 to move, and the elastic force of the elastic member 65 and the magnetic force of the electromagnet 64 can be used to cooperate to drive the adjustment plate 61 in different directions, thereby facilitating the driving of the adjustment plate 61 by turning the electromagnet 64 on and off, and realizing the switching of the position of the adjustment plate 61.

[0044] Furthermore, if Figure 2 As shown, a telescopic guide rod 66 is connected between the magnetic member 63 and the adapter block 20. The elastic member 65 is a tension spring and is mounted on the telescopic guide rod 66. Specifically, the elastic member 65 is connected to the magnetic member 63 and the adapter block 20 respectively. This allows the telescopic guide rod 66 to position and guide the elastic member 65 and the adjustment plate 61, improving the stability and reliability of the movement of the adjustment plate 61.

[0045] Specifically, the adjustment plate 61 and the magnetic member 63 are connected via an adapter plate 67. A plurality of telescopic guide rods 66 and elastic members 65 are provided above and below the adapter plate 67. This facilitates the connection between the adjustment plate 61 and the magnetic member 63.

[0046] Advantageously, as Figure 2 and Figure 3 As shown, the flow regulating devices 60 are multiple and stacked along the axial direction of the flow channel hole 21, and the diameters of the multiple regulating holes 611 are different. In this way, when different flow rates are required, the regulating plates 61 with regulating holes 611 of different diameters can be moved to the desired adjustment position, and the regulating holes 611 of different sizes can be used to limit the flow of the liquid medicine, thereby achieving adjustment of multiple flow levels. This further improves the flow regulation capability of the nasal cleaning device 1, facilitates meeting the different needs of different users, and improves the applicability of the nasal cleaning device 1.

[0047] More advantageously, if Figure 3 As shown, a semicircular avoidance groove 612 is provided on the edge of the regulating plate 61. When the regulating plate 61 is in the avoidance position, the avoidance groove 612 is flush with the flow channel hole 21. This allows the regulating plate 61 to avoid the flow channel hole 21 when in the avoidance position, thereby reducing the required stroke of the regulating plate 61 and facilitating the miniaturization of the flow regulating device 60. Furthermore, when the regulating plate 61 is in the avoidance position, the avoidance groove 612 is flush with the flow channel hole 21, thereby maintaining the original flow rate of the flow channel hole 21.

[0048] Figure 1-Figure 5Figure 1 shows some examples of nasal cleaning devices 1 according to the present invention. Figure 1 、 Figure 2 and Figure 5 As shown, the upper end of the flushing tube 40 is provided with a drug delivery head 70, and the drug delivery head 70 is provided with an air bag layer 71 on the outer cover. The air bag layer 71 is connected to a gas drive device 73 through an air supply pipe 72, and the gas drive device 73 is provided on the storage tank 10. Specifically, the gas drive device 73 can be provided on the flow regulating device 60. The gas drive device 73 can be an air pump. In this way, the air bag layer 71 can be inflated or deflated by the gas drive device 73 to expand or contract the air bag layer 71. The diameter of the outer peripheral surface of the air bag layer 71 can be adjusted according to the size of the user's nostrils. Compared with the nasal cleaning device in the related art, it can prevent the drug delivery head from being too small to achieve effective cleaning, and prevent the drug delivery head from being too large to make the user feel uncomfortable or even damage the nasal mucosa. In this way, the applicability of the nasal cleaning device 1 can be further improved.

[0049] Advantageously, as Figure 2 As shown, a partition 11 is provided in the storage tank 10, and the partition 11 divides the space in the storage tank 10 into a liquid storage chamber 12 and a waste liquid chamber 13. The storage tank 10 is provided with a liquid inlet 14 connected to the liquid storage chamber 12 and a liquid discharge port 15 connected to the waste liquid chamber 13. The liquid inlet 14 and the liquid discharge port 15 are both provided with an openable and closable sealing member 16. The suction pipe 30 extends into the liquid storage chamber 12, and a collecting tray 80 is provided below the dosing head 70. The upper surface of the collecting tray 80 is provided with a collecting ring groove 81. The outer diameter of the collecting ring groove 81 is larger than the outer diameter of the airbag layer 71. The collecting ring groove 81 is connected to the waste liquid chamber 13 through a collecting pipe 82. In this way, before washing, the sealing member 16 of the liquid inlet 14 can be opened to replenish the liquid into the liquid storage chamber 12 through the liquid inlet 14. During the washing process, the waste liquid after washing the nasal cavity flows through the outer surface of the air bag layer 71 to the collection ring groove 81 of the collection tray 80, and then flows into the waste liquid chamber 13 through the collection tube 82. The waste liquid after washing is collected and stored in the waste liquid chamber 13. After use, the waste liquid can be discharged by opening the sealing member 16 of the liquid discharge port 15.

[0050] More advantageously, if Figure 2 and Figure 5 As shown, an outer sleeve 41 is provided outside the irrigation tube 40, and the outer circumference of the irrigation tube 40 is spaced apart from the inner circumference of the outer sleeve 41 to form a tracheal cavity 42, through which the air supply tube 72 passes. In this way, the air supply tube 72 can be built into the outer sleeve 41, which is convenient for protecting the air supply tube 72.

[0051] Specifically, the airbag layer 71 is removably covered with a flexible cleaning layer, such as a cotton pad. The flexible material prevents damage to the nasal cavity. During cleaning, the outer cannula 41 can be rotated to rotate the dosing head 70 and the airbag layer 71 within the nasal cavity, allowing the flexible cleaning layer covering the airbag layer 71 to remove foreign matter from the nasal cavity.
